Material and working principle of slide rail
Material of slide rail: iron (zinc and lacquer), copper and other alloys.
The working principle is to achieve the expansion by rolling the ball or roller between the track and the track.
The structure and use of slide rail
A slide rail structure consists of a sliding rail seat, a ball sliding seat, a sliding plate and a homing component. The slide seat is slipped on both sides of the sliding rail seat, and the sliding plate is embedded in the slide seat and can slip by using the two ball sliding seats. The rear end group of the slide plate is provided with a zigzag guide slot. The base is composed of a base, a slider, and a spring, which is fixed on the back end of the slide rail seat and has a guide slot. The front end of the guide groove is bent to form a certain position, and the slider is slid in the guide groove and is pulled by a spring to bring back the resilience back to the rear end of the base, and the base is slow on the base. Flush elastic block sliding plate and ball sliding seat;
It is characterized in that the spring is a single set method, the front end is connected to the slider, the back ends round the rear section of the base, and then twists and zigzag the positioning hook arranged on the side of the circular convex tube, which is constructed by the first buffer sheet and the two buffer sheet, and the first buffer is relative to the base. The position of the middle part of the middle section is a plate body bending to bend into an inverted U shape, and the back end of the ball sliding seat is placed in elastic stop when the back end of the ball sliding seat is returned. The second buffer sheet is located between the guide slot and the circular convex tube above the base.
Main points of selecting and buying slideways
1. features of the bottom bracket: the track is hidden at the bottom of the drawer, durable, sliding without friction, no noise, and can be self closing.
2. steel ball type features: smooth sliding, convenient installation, very durable. The special structure of the rail and the precision steel ball ensure stability. It can be directly mounted on a side board or in a slot installed or loaded into a drawer side board, and their specifications are (mm) 250300350400450500550600. In addition, there are many special tracks, such as frame rails, mesa ball tracks, etc.
3. selection factors: there are several points to be paid attention to when choosing the slide rail, one is the proportion, the two is the surface treatment, the three is the structure and the material, and the four is the applicability.
4. weight: usually refers to the same length or volume unit weight, which refers to the same type (such as two track) weight of the slide.
5. surface treatment: this can be seen from the naked eye. You don’t need to listen to too many sales words.
6. structure and material: look at the thickness of the cross section of the metal material of the slideway, and its structure. The quality of the slide rail, which usually uses a lot of plastic parts, is not as good as the whole metal slide.
7. applicability: stretching the slideway can feel the weight, strength and so on.
Selection of slide rail
1. test steel.
How much can the drawer bear? It mainly depends on whether the rail steel is good or not. The thickness of the drawers of different specifications is different, and the bearing capacity is different. When you choose to buy, you can pull out the drawer and press it slightly with your hands to see if it will loose, sway or flip.
2. look at the material.
The material of the pulley determines the comfort of the drawer when sliding. Plastic pulley, steel ball and wear-resistant nylon are the three most common materials for pulley, wear-resistant nylon is the top quality, while sliding is quiet and silent. To see whether the pulley is good or bad, you can push and pull the drawer with one finger. It should be free from astringency and no noise.
3. pressure device.
In the hardware fittings of cabinets, apart from the slide rails and closely related drawers and hinges, there are also many hardware such as pneumatic and hydraulic devices. These accessories are adaptable to the constantly changing cabinet design. They are mainly used for flip door and vertical lift doors. Some devices have three points, or even more point of the brake position, installation of the pressure device cabinet, saving power and quiet, it is suitable for the elderly to use the key points to see the pressure device is good or not to use, try more! See if labor, braking is convenient. But it should be noted that the pressure device is good, but the price is more expensive.
