Description

Technical Field

[0001] The invention relates to a slide rail, in particular to a slide rail with damping. Background Art

[0002] As a device that can provide motion resistance, the damper has the function of absorbing energy and reducing shock. Therefore, in order to reduce the excessive noise caused by the impact when closing drawers, doors and windows, the damper structure is often used on the slide rails of drawers, doors and windows. Conventional dampers need to be equipped with springs and cylinder structures of the same length. During the contraction of the spring, the cylinder can be slowly compressed to slowly close the drawers, doors and windows. However, since the length of the cylinder must match the spring, the cylinder length is too long, which will occupy a larger slide rail space and result in a larger slide rail size. Summary of the invention

[0003] The invention provides a slide rail with damping to reduce the size of the slide rail.

[0004] The present invention provides a damping slide rail, comprising a rail, wherein at least one end of the rail is provided with a damper, wherein the damper comprises a tension member, a damping member, and a slider, wherein the slider is slidably installed on the rail, wherein the slider has a first position and a second position on the rail, and the tension member can pull the slider to move from the first position to the second position, wherein the damping member comprises a limit rail and a telescopic cylinder, wherein the telescopic cylinder is slidably installed on the limit rail, wherein the telescopic cylinder has a first limit position and a second limit position on the limit rail, wherein the limit rail has at least one side wall having an angle with the direction of the rail, and wherein the side wall having an angle with the direction of the rail is inclined toward the telescopic cylinder from the first limit position to the second limit position, and wherein during the sliding process of the slider from the first position to the second position, the slider drives the telescopic cylinder to move from the first limit position to the second limit position, and during the movement, one end of the telescopic cylinder abuts against the side wall having an angle with the direction of the rail.

[0005] Furthermore, the sliding block is fixedly connected to the telescopic cylinder.

[0006] Furthermore, a limiting member is provided on the sliding block, a sliding groove is provided on the sliding rail, and one end of the limiting member is inserted into the sliding groove.

[0007] Furthermore, an arc-shaped hole is provided on the slider, and the limit member is slidably installed on the arc-shaped hole. The slide groove includes a straight groove portion and a bent portion. One end of the straight groove portion is connected to one end of the bent portion. When the slider is in the first position, the bent portion overlaps with the arc-shaped hole, and the limit member can slide along the arc-shaped hole, and one end of the limit member is inserted into the bent portion during the sliding process.

[0008] Furthermore, a sliding member is also provided on the track, and the sliding member is slidably connected to the track. A guide member is provided at one end of the sliding member facing the slider, and a guide groove that can be engaged with a limiting member is provided on the guide member. During the movement of the guide member toward the slider, the limiting member slides toward one end of the bending part close to the straight groove part under the action of the guide groove.

[0009] Furthermore, the telescopic cylinder is an air cylinder, and two ends of the air cylinder directly abut against two side walls of the limit rail.

[0010] Furthermore, the limit rail is a tapered rail, and the width of the limit rail gradually decreases from the first limit position to the second limit position. When the telescopic cylinder moves from the first limit position to the second limit position, both ends of the telescopic cylinder respectively abut against two side walls of the limit rail.

[0011] Furthermore, at least one end of the telescopic cylinder is provided with a contact piece, and the telescopic cylinder abuts against the limit rail through the contact piece.

[0012] Furthermore, the contact member is provided with a ball, and the telescopic cylinder abuts against the limit rail through the ball.

[0013] Furthermore, the damping member also includes a fixer, the fixer is slidably mounted on the limit rail, and the telescopic cylinder is inserted into the fixer.

[0014] Furthermore, there are two tension members, and the two tension members are respectively connected to two sides of the slider close to the track.

[0015] Compared with the prior art, the present invention utilizes the side wall of the limit rail to abut against the telescopic cylinder, so that the force of the telescopic cylinder is converted into resistance during the movement of the telescopic cylinder from the first limit position to the second limit position, thereby applying resistance to the sliding block in the process of sliding from the first position to the second position, playing a damping role, and at the same time avoiding the use of long-sized cylinders, reducing the space required for the damping member, so that the damping slide rail can be further reduced in size, thereby achieving the effect of saving space.

The limit rail 31 is provided with at least one side wall 311 having an angle with the direction of the track 1, and the side wall 311 having an angle with the direction of the track 1 is inclined toward the telescopic cylinder 32 from the first limit position to the second limit position. During the sliding process of the slider 4 from the first position to the second position, the slider 4 drives the telescopic cylinder 32 to move from the first limit position to the second limit position, and during the movement, one end of the telescopic cylinder 32 abuts against the side wall 311 having an angle with the direction of the track 1.

[0025] Optional, such as Figure 1-3 As shown, the slide block 4 is fixedly connected to the telescopic cylinder 32 .

[0026] Among them, Figure 1-3 As shown, the telescopic cylinder 32 is installed at one end of the slider 4 close to the limiting rail 31, and the slider 4 pushes the telescopic cylinder 32 to move toward the second limiting position during the movement toward the second position.

[0027] The embodiment of the present invention utilizes the side wall of the limit rail to abut against the telescopic cylinder, so that the force of the telescopic cylinder is converted into resistance during the movement of the telescopic cylinder from the first limit position to the second limit position, thereby applying resistance to the slider in the process of sliding from the first position to the second position, playing a damping role, and at the same time avoiding the use of a long cylinder, reducing the space required for the damping member, so that the damping slide rail can be further reduced in size, thereby achieving the effect of saving space.

[0028] Optional, such as Figure 4 As shown, a limiting member 41 is provided on the slide block 4 , a sliding groove 11 is provided on the slide rail 1 , and one end of the limiting member 41 is inserted into the sliding groove 11 .

[0029] In particular, such as Figure 4 As shown, the slider 4 is provided with an arc hole 42, and the limit member 41 is slidably installed on the arc hole 42. The slide groove 11 includes a straight groove portion 111 and a bent portion 112. One end of the straight groove portion 111 is connected to one end of the bent portion 112. When the slider 4 is in the first position, the bent portion 112 overlaps with the arc hole 42, and the limit member 41 can slide along the arc hole 42, and one end of the limit member 41 is inserted into the bent portion 112 during the sliding process.

[0030] The slide slot 11 is located on a limit rail 31 , and the limit rail 31 is fixed to one end of the track 1 .

[0031] In particular, such as Figure 4 As shown, the track 1 is also provided with a sliding member 12, and the sliding member 12 is slidably connected to the track 1. The sliding member 12 is provided with a guide member 121 at one end facing the slider 4, and the guide member 121 is provided with a guide groove 1211 that can be engaged with the limit member 41. During the movement of the guide member 121 toward the slider 4, the limit member 41 slides toward the end of the bending portion 112 close to the straight groove portion 111 under the action of the guide groove 1211.

[0032] Among them, Figure 4 As shown, the track 1 is a telescopic track structure, and the sliding member 12 is the inner track of the telescopic track structure.

[0033] Optional, such as Figure 5 As shown, the telescopic cylinder 32 is an air cylinder, and both ends of the air cylinder directly abut against the two side walls of the limiting rail 31 .

[0034] Optional, such as Figure 5 As shown, the limit rail 31 is a tapered rail, and the width of the limit rail 31 gradually decreases from the first limit position to the second limit position. When the telescopic cylinder 32 moves from the first limit position to the second limit position, the two ends of the telescopic cylinder 32 respectively abut against the two side walls 311 of the limit rail 31.

[0035] Among them, Figure 5 As shown, when the telescopic cylinder 32 moves from the first limit position to the second limit position, the telescopic cylinder 32 is compressed due to the reduction in the width of the limit rail, and the telescopic cylinder 32 applies pressure to the side wall 311 of the limit rail 31, and the pressure is converted into a resistance opposite to the pulling force, thereby playing a damping role.

[0036] Optional, such as Figure 6 As shown, at least one end of the telescopic cylinder 32 is provided with a contact piece 321 , and the telescopic cylinder 32 abuts against the limiting rail 31 through the contact piece 321 .

[0037] Among them, Figure 6 As shown, the contact member 321 is a sleeve-type structure, which is sleeved on both ends of the telescopic cylinder 32. The contact member 321 can be selected as a plastic member, which can increase the contact area between the telescopic cylinder 32 and the limit rail 31, improve the durability of the telescopic cylinder 32 (cylinder), and avoid piston damage.

[0038] In particular, such as Figure 6 As shown, the contact member 321 is provided with a ball, and the telescopic cylinder 321 abuts against the limiting rail 31 through the ball.
