[0002] The connection between the drawer and the cabinet requires the use of a slide rail, which can reduce the resistance and noise of pulling out the drawer. When the drawer is slid into the cabinet with the currently commonly used slide rail, when the drawer is slid into the cabinet with a large force, it is easy to cause the drawer to hit the cabinet at a fast speed. The direct impact will not only produce a large noise, but also may cause structural damage to the drawer and the cabinet. As a result, long-term unbuffered closing may cause wear and tear on the connection between the slide rail and the drawer, thereby shortening the service life of the drawer and the slide rail.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] The utility model provides Figure 1-3 A steel ball slide rail is shown, comprising:

[0019] A first slide rail 1 is slidably connected to a second slide rail 2 and a plurality of steel balls 9 are rollingly connected on both sides of the second slide rail 2. The rolling of the steel balls 9 in the second slide rail 2 can significantly reduce the friction with the third slide rail 3, making the movement of the third slide rail 3 smoother and more stable, while also reducing the noise and wear caused by friction, thereby extending the service life of the slide rail.

[0020] The third slide rail 3 is slidably connected to the second slide rail 2 and one end of the third slide rail 3 is clamped with the buffer component. The buffer component is arranged in the first slide rail 1 and is used to buffer the sliding of the third slide rail 3. The slider 4 of the buffer component is clamped with the third slide rail 3, so that the third slide rail 3 can be buffered through the damping rod 5 connected to the slider 4 when sliding.

[0021] The buffer assembly includes a fixed block 6 and a spring 7. The fixed block 6 is arranged in the first slide rail 1 and a slide rod 8 is arranged at one end of the fixed block 6. The slider 4 is slidably connected to the surface of the slide rod 8. The spring 7 is provided in two groups and the two groups of springs 7 are respectively arranged on both sides of the fixed block 6.

[0022] One end of the spring 7 is connected to the fixed block 6 , and the other end of the spring 7 is movably passed through the fixed block 6 and then connected to the slider 4 .

[0023] The damping rod 5 is disposed in the fixing block 6 and the piston rod of the damping rod 5 is connected to the sliding block 4 .

[0024] The surface of the third slide rail 3 is provided with a block 10, the surface of the block 10 is provided with a slot 11, the surface of the slider 4 is provided with a column 12, the column 12 and the slot 11 are engaged with each other, and the slot 11 on the surface of the block 10 is engaged with the column 12 on the surface of the slider 4 in the first slide rail 1 when the third slide rail 3 continues to move, so that the third slide rail 3 and the slider 4 are engaged and fixed.

[0025] The surface of the third slide rail 3 is rotatably connected to the limiting block 13 located on one side of the card block 10, and one end of the second slide rail 2 is provided with two groups of short blocks 14 and a slot 15 is provided between the two groups of short blocks 14. When the third slide rail 3 is slidably connected with the second slide rail 2, the limiting block 13 on the surface of the third slide rail 3 can pass through the slot 15 between the two groups of short blocks 14 on the surface of the second slide rail 2, so that the limiting block 13 can be limited by the two groups of short blocks 14 to prevent the third slide rail 3 from being pulled off from the second slide rail 2. Since the limiting block 13 is designed to be inclined, the limiting block 13 can limit the short block 14 at one end of the second slide rail 2. When the third slide rail 3 needs to be removed from the second slide rail 2, it is only necessary to toggle the handle on one side of the limiting block 13 to drive the limiting block 13 to rotate, so that the limiting block 13 is in a horizontally parallel state, and the limiting block 13 can pass through the slot 15 to complete the removal of the third slide rail 3 and the second slide rail 2.

[0026] The steel ball slide rail is connected with the two sides of the drawer by using two third slide rails 3, and the two first slide rails 1 are connected with the two sides of the cabinet body, and the third slide rails 3 on the two sides of the drawer are slidably connected with the second slide rails 2, and when the third slide rail 3 slides into the second slide rail 2, the limit block 13 on the surface of the third slide rail 3 can pass through the slot 15 between the two groups of short blocks 14 on the surface of the second slide rail 2, so that the limit block 13 can be limited by the two groups of short blocks 14 to prevent the third slide rail 3 from being pulled off from the second slide rail 2, and the groove 11 on the surface of the block 10 is engaged with the clamping column 12 on the surface of the slider 4 in the first slide rail 1 under the continuous movement of the third slide rail 3, so that the third slide rail 3 is clamped and fixed with the slider 4, and when the third slide rail 3 moves into the first slide rail 1 and is clamped and fixed with the slider 4, After the installation is completed, when the drawer is pulled outward, the third slide rails 3 on both sides of the drawer slide in the second slide rails 2 and the sliding of the third slide rails 3 will pull the piston rod of the damping rod 5 to move, thereby extending the piston rod and pulling the damping rod 5 while stretching the springs 7 on both sides, thereby completing the opening of the drawer. When the drawer is pushed into the cabinet, the third slide rail 3 slides in the second slide rail 2 and pushes the slider 4 to move and the piston rod will retract into the damping rod 5 while the slider 4 moves, and drive the stretched spring 7 to reset. The damping rod 5 cooperates with the spring 7 to gradually slow down the closing speed of the drawer to achieve the purpose of buffering, so that the synergistic effect of the damping rod 5 and the spring 7 can effectively reduce the damage caused by impact and friction between the slide rails, thereby greatly extending the service life of the drawer and the slide rails.
