(1) Locks
1, characteristics
Nowadays, there are many kinds of locks on the market. In terms of door locks, portal locks, bedroom locks, passage locks, bathroom locks, etc. are used according to the purpose; ball-type locks, handle locks, mortise locks, and locks are arranged according to the shape. The ball lock and handle lock have three functions: lock, handle and ball touch. To install a door handle, it is necessary to install a door handle.
1 household door lock: It plays the role of insurance safety, so it is also called insurance lock or anti-theft lock.
2-channel lock: the function of the handle and the bead of the door, no insurance function, suitable for the door lock of the kitchen, the hall, the living room, the dining room and the children.
3 bathroom lock: features can be locked inside, can be opened with a key outside the door, suitable for the bathroom or bathroom.
4 bedroom lock: Secured inside, must be opened with a key, suitable for bedroom and balcony doors.
The materials used for the locks are mainly copper, stainless steel, zinc alloy, steel, aluminum or aluminum alloy.
1Copper: It is one of the most widely used lock materials. It has good mechanical properties, good corrosion resistance and processing properties, and its color is beautiful. Especially for copper forged handles and other locks, the surface is flat, the density is good, and there is no air hole. , sand holes.
2 stainless steel: durable, the more you use the brighter. It has good strength, strong corrosion resistance and constant color.
3 zinc alloy material: its strength and anti-rust ability is poor, the advantage is easy to make complex patterns of parts, especially pressure casting. Most of the locks on the more complex patterns seen in the market are zinc alloys.
4 steel: better strength, lower cost, generally coated, but easy to rust.
5 Aluminum or aluminum alloy: Ordinary aluminum alloy (except for aerospace) is soft and light, and the material strength is lower, but it is easy to process.
2, choose
Consumers should choose the copper core, but it should be noted that some of the cores are plastic, only a layer of copper "copper core" is wrapped in the core. The copper-plated nickel and iron-plated nickel have almost the same appearance, but the price varies greatly. Generally, the copper is silent, the iron is not muted, and the copper is fine and the work is rough. When the ball type is installed, if the eccentric core is not installed, it is easy to cause problems during use. Now there is a kind of backhand, the handle is gently lifted, it can be trivial, very convenient, but it is easy to put the key in the house.
Now, the fastest selling is the lock, the ball lock is out of date, and generally not used. Relatively speaking, when turning the trivial, the smaller the sound, the better, the handle turns a little, the trivial should follow up a little. In terms of the shape of the key, the "pit" key is more secure than the "tooth" key, but the "pit" key must be lost to the original factory. The more the square tongues are, the better the safety. Pay attention to the following points when consumers choose trivial.
1 should choose products with high reputation, stable quality and good after-sales service.
2 First check whether the packaging of the purchased product is complete (including the product's implementation standards, grades, manufacturing company name, address, production date), whether the packaging is firm, the contents of the manual are consistent with the product, and the caution is exaggerated and does not match the facts. phenomenon.
3 Observe the appearance quality of the product, including whether the lock head, the lock body, the lock tongue, the handle and the cover plate parts and related accessories are complete, whether the surface color of the plated parts and the painted parts is bright and uniform, and whether there are signs of rust or oxidation. damaged.
4 Check whether the product use function is reliable and flexible. Two or more products should be selected for comparison check. Especially when purchasing the two-way lock product, all the keys must be used to test the inner and outer locks separately. You should also check the insurance organization of the product. It is recommended to try each lock at least three times.
5 Select the equipment according to the use environment, such as dry humidity, door structure, thickness, left or right door, inner door or outer door.
6 The mutual opening rate is the ratio of the lock to the key. The less the lock is opened by a key, the stronger the safety and reliability of the lock. Consumers should try to pick a lock with a large number of key teeth when purchasing, because the more the number of teeth of the key, the greater the difference, the lower the mutual opening rate of the lock.
(2) Handle 1. Features
The handle is divided into a single metal, alloy, plastic, ceramic, glass, etc. from the material; the shape is divided into a tube shape, a strip shape, a sphere and various geometric shapes; from the style, there is a single strip, double head, Exposed, closed, etc.; from the style to the point is more avant-garde or casual, there are ropes or hanging beads of the nostalgic hand.
2, choose
There are too many patterns for the handles, and the styles are constantly being refurbished. The choices for the handles are also good. From the material point of view, all copper, all stainless steel is better, alloy, electroplating is poor, plastic is on the verge of elimination.
The handle has two fixing methods, namely, screw and glue. Generally, it is firmly fixed by screws, and the glue is not practical. All stainless steel handles and stainless steel handles look similar and can be tried with magnets. The handle must pay attention to the style, function and place of the furniture when it is selected. Generally speaking, the relationship between the handle and the furniture has two principles, either eye-catching or concealed.
The entrance is one of the key decorative parts in the living room. The handle of the entrance cabinet can emphasize its decoration. In general, the symmetrical decorative door is fitted with two luxurious and beautiful handles, while the shoe cabinet should be selected with a single-handed handle with a color close to the board. These furniture-based furniture should have a recessed handle that does not interfere with the owner's use. The handle of the food decoration cabinet can be adapted to its own eye-catching style, and the double-headed handle with luster and contrast with the furniture color is purchased. The handle of the TV cabinet can be considered to be similar to the black color of the electric device or the TV counter surface, such as black, gray, dark green, and sub-gold. The reason is that the frequency of opening the doors of these places is low, and then it is to ensure that people do not get involved. The furniture in the study or studio can imitate the practice of the office building, and choose the handle of the simple and correct. There are not many cabinet doors in the bathroom. It is suitable for selecting ceramic or plexiglass handles with miniature single-head ball. The color or material should be similar to the cabinet.
(three) hinge
1, characteristics

Flat hinges are mostly used for room wooden doors, spring hinges are mostly used for cabinet doors, self-closing hinges are mostly used for toilets, and glass hinges are used for glass doors.
2, the choice of flat hinges generally have four bearings, the quality of the flat hinge depends mainly on the quality of the bearing, relatively speaking, the larger the diameter of the bearing, the better the thicker the wall, the better the hand, the hinge is one piece, let the other piece free It is better to slide down, even and slow. The spring (pipe) hinge has a full cover, a half cover, and no cover, and is used for three different connection modes of the door and the cabinet. The choice of spring hinges is mainly for the brand. The springs of the small brand hinges are mostly prone to aging and fatigue, causing the cabinet door to sag. Stainless steel and steel plate hinges are thinner, but have good toughness and are not easily broken. Although the cast iron hinge is thicker, it is easy to break. Some merchants deliberately deceive consumers, saying that the thicker and more expensive the siding, the different materials. When selecting the spring hinge, also pay attention to the lack of adjustment screws on the hinge, because this screw is not easy to match, not sold.
The thickness of the flat hinge wall is related to the weight of the door leaf. Generally, the door leaf of 40 kg or more, the thickness of the flat hinge wall is more than 3.2 mm. Most of the 10 yuan flat plate hinges do not have full bearings, generally two are really two fake. The price of spring hinges is quite different. The façades of well-known brands are thicker and workmanship is fine; the siding of small brands is thin and the workmanship is rough. The glass hinge has the intermediate shaft and the upper and lower shafts. The intermediate shaft needs to be punched and used less and less; the upper and lower shafts do not need to be punched, which is the choice of most consumers. The glass hinge is equipped with glass nails and glass holders. It is available in all stainless steel and stainless steel. All stainless steel is more expensive.

5 mosquito nails are all copper, small nail holes, mainly used for decorative panels.
6 special nails with thread, mainly used for nail baseboard, thread structure is not easy to loose.
2. Choose the largest amount of gas nails. The air nails are sold by the disc. When choosing, the main reason is whether the arrangement is neat and the length is the same. It should be noted that due to the large number of gas nails per cartridge, the actual number of gas nails is less than the nominal number.
(5) hanging wheel
1. Features The hanging wheel is used for sliding doors of balconies, kitchens and restaurants, with imported hanging wheels and domestic hanging wheels. Most imported hanging wheels are only imported bearings, and other parts are made in China.
2, the choice of imported hanging wheels because of the use of imported bearings, most of them are ultra-quiet, the service life is about 15-20 years, the price is about 80 yuan.
