Description

Technical Field

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

[0002] A damper, a device that provides resistance to movement, absorbs energy and reduces shock. Therefore, to reduce the excessive noise generated by the impact of drawers, doors, and windows during closing, dampers are often used on the slide rails of these systems. Conventional dampers require a spring and a cylinder of the same length. As the spring contracts, the cylinder slowly compresses, causing the drawer, door, or window to close slowly. However, since the cylinder length must match the spring, an excessively long cylinder would occupy more space on the slide rail, resulting in larger rail dimensions. Summary of the Invention

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

[0004] The present invention provides a linear push 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, a slider, and an abutment member, wherein the slider is slidably mounted 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 from the first position to the second position, wherein a limit rail is provided on the slider, wherein the limit rail has at least one side wall having an angle with the direction of the rail; wherein the damping member comprises a telescopic cylinder, wherein the telescopic cylinder is mounted on the rail; wherein the rail is provided with an abutment groove, The abutment is slidably installed in the abutment groove, and the telescopic cylinder abuts against the angled side wall of the limit rail through the abutment. The abutment groove and the angled side wall of the limit rail and the rail all have an inclination angle. The abutment is provided with a first abutment position and a second abutment position in the abutment groove. During the sliding process of the slider from the first position to the second position, the slider drives the abutment to slide from the first abutment position to the second abutment position, and the abutment compresses the telescopic cylinder during the sliding process; the projected length of the abutment groove in the rail direction is less than the length of the limit rail.

[0005] 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.

[0006] 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.

[0007] Furthermore, a sliding member is 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 is provided on the guide member that can engage with the limiting member. During the movement of the guide member toward the slider, the limiting member slides toward the end of the bending portion close to the straight groove portion under the action of the guide groove.

[0008] Furthermore, the telescopic cylinder is provided with a contact piece, the contact piece is provided with a contact surface, the contact piece abuts against the abutting piece via the contact surface, and the contact surface forms an angle with the track direction.

[0009] Furthermore, the limiting rail is a conical rail, and the two side walls of the limiting rail both have an angle with the track direction. There are two abutment members, and the two abutment members respectively abut the two side walls of the limiting rail. The contact member is provided with two symmetrical contact surfaces, and the two contact surfaces respectively abut the two abutment members.

[0010] Furthermore, the contact member is a conical member, and the two contact surfaces are two sides of the conical member.

[0011] Furthermore, the abutment member is cylindrical.

[0012] Furthermore, a conical clamping piece is provided on one side of the contact piece, and a conical clamping groove is provided on the slider. When the slider is located at the second position, the conical clamping piece is engaged with the conical clamping groove.

[0013] Furthermore, there are two tension members, and the two tension members are respectively connected to the two sides of the slider close to the track.

[0014] Compared with the prior art, the present invention utilizes abutments to abut against the side walls of the limit rail and the telescopic cylinder respectively. When the slider moves, the abutments move relative to the slider in the direction of the track, compressing the telescopic cylinder, so that the force of the telescopic cylinder is converted into resistance during the movement of the slider from the first position to the second position, thereby playing a damping role. At the same time, the use of long cylinders is avoided, and the space required for the damping member is reduced, so that the linear push damping slide rail can be further reduced in size, thereby achieving the effect of saving space.

[0022] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0023] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0024] The embodiment of the present invention discloses a linear push damping slide rail, such as Figure 1-7 As shown, it includes a track 1, and a damper is provided at at least one end of the track 1. The damper includes a tension member 21, a damping member 22, a slider 23, and an abutment member 24. The slider 23 is slidably installed on the track 1. The slider 23 has a first position and a second position on the track 1. The tension member 21 can pull the slider 23 from the first position to the second position. A limiting rail 231 is provided on the slider 23, and the limiting rail 231 has at least one side wall 2311 with an angle to the direction of the track 1; the damping member 22 includes a telescopic cylinder 221, and the telescopic cylinder 221 is installed on the track 1; the track 1 is provided with an abutment groove 11, and the abutment member 24 slides It is dynamically installed in the abutment groove 11, and the telescopic cylinder 221 abuts against the angled side wall 2311 of the limit rail 231 through the abutment member 24. The abutment groove 11, the angled side wall 2311 of the limit rail 231, and the track 1 all have an inclination angle. The abutment member 24 is provided with a first abutment position and a second abutment position in the abutment groove 11. During the sliding process of the slider 23 from the first position to the second position, the slider 23 drives the abutment member 24 to slide from the first abutment position to the second abutment position, and the abutment member 24 compresses the telescopic cylinder 221 during the sliding process; the projected length of the abutment groove 11 in the direction of the track 1 is less than the length of the limit rail 231.

[0025] The telescopic direction of the telescopic cylinder 221 is the same as that of the track 1 .

[0026] When the slider is in the first position, Figure 2 、 Figure 3 As shown, the abutment member 24 is located at the first abutment position of the abutment groove 11 and abuts against one end of the telescopic cylinder 221. When the tension member 21 drives the slider 23 to slide toward the second position, the limit rail 231 presses against the abutment member 24, causing the abutment member 24 to slide along the abutment groove 11 toward the second abutment position. The abutment member 24 compresses the telescopic cylinder 221. The compressed length of the telescopic cylinder 221 is related to the projection of the abutment groove 11 in the direction of telescopic cylinder 221 extension and contraction. Since the projection length of the abutment groove 11 in the direction of track 1 is less than the length of the limit rail 231 (the length of the limit rail 231 in the direction of track 1), the compressed length of the telescopic cylinder 221 is less than the length of the limit rail 231.

[0027] The embodiment of the present invention utilizes abutment members to abut against the side walls of the limit rail and the telescopic cylinder respectively. When the slider moves, the abutment members move relative to the slider in the direction of the track, compressing the telescopic cylinder, so that the force of the telescopic cylinder is converted into resistance during the movement of the slider from the first position to the second position, thereby playing a damping role. At the same time, it avoids the use of long cylinders, reduces the space required for the damping member, and enables the linear push damping slide rail to be further reduced in size, thereby achieving a space-saving effect.

[0028] Optional, such as Figure 3 、 Figure 4 As shown, a limiting member 232 is provided on the slider 23 , a sliding groove 12 is provided on the track 1 , and one end of the limiting member 232 is inserted into the sliding groove 12 .

[0029] In particular, such as Figure 4 As shown, the slider 23 is provided with an arc-shaped hole 233, and the limiting member 232 is slidably installed on the arc-shaped hole 233. The slide groove 12 includes a straight groove portion 121 and a bent portion 122. One end of the straight groove portion 121 is connected to one end of the bent portion 122. When the slider 23 is in the first position, the bent portion 122 overlaps with the arc-shaped hole 233, and the limiting member 232 can slide along the arc-shaped hole 233, and one end of the limiting member 232 is inserted into the bent portion 122 during the sliding process.

[0030] Among them, such as Figure 1-7 As shown, a fixing member 13 is provided on the track 1 , the abutting groove 11 and the sliding groove 12 are located on the fixing member 13 , and the damping member 22 is fixedly installed on the fixing member 13 .

[0031] In particular, such as Figure 1-7As shown, the track 1 is further provided with a sliding member 3, and the sliding member 3 is slidably connected to the track 1. The sliding member 3 is provided with a guide member 31 at one end facing the slider 23, and the guide member 31 is provided with a guide groove 311 that can engage with the limit member 232. During the movement of the guide member 31 toward the slider 23, the limit member 232 slides toward the end of the bending portion 122 close to the straight groove portion 121 under the action of the guide groove 311.

[0032] The track 1 is a telescopic track structure, and the sliding member 3 is the inner track of the telescopic track structure.

[0033] Optional, such as Figure 1-7 As shown, the telescopic cylinder 221 is provided with a contact member 222 , and the contact member 222 is provided with a contact surface 2221 . The contact member 222 abuts against the abutting member 24 via the contact surface 2221 , and the contact surface 2221 forms an angle with the direction of the track 1 .

[0034] In particular, such as Figure 1-7 As shown, the limiting rail 231 is a conical rail, and the two side walls 2311 of the limiting rail 231 both have an angle with the direction of the track 1. There are two abutment members 24, and the two abutment members 24 respectively abut against the two side walls 2311 of the limiting rail 231. The contact member 222 is provided with two symmetrical contact surfaces 2221, and the two contact surfaces 2221 respectively abut against the two abutment members 24.

[0035] Among them, such as Figure 5 As shown, the abutment member 24 slides along the abutment groove 11 under the action of the limiting rail 231, and the abutment member 24 presses against the contact surface 2221 of the contact member 222. Since there is an angle between the abutment groove 11 and the contact surface 2221, when the contact member 222 slides along the direction of the track 1, the abutment member 24 and the contact surface 2221 also slide relative to each other.

[0036] In particular, such as Figure 1-7 As shown, the contact member 222 is a conical member, and the two contact surfaces 2221 are two sides of the conical member.

[0037] When the slider is in the first position, Figure 2 、 Figure 3 As shown, the abutment member 24 is located at the first abutment position of the abutment groove 11 and abuts against the wider end of the contact member 222. When the tension member 21 drives the slider 23 to slide to the second position, the limit rail 231 presses the abutment member 24, causing the abutment member 24 to slide along the abutment groove 11. The abutment member 24 applies pressure to the contact member 222, causing the abutment member 24 and the contact surface 2221 to slide relative to each other, as shown in FIG. Figure 5-7As shown, when the slider 23 is located at the second position, the abutting member 24 is located at the second abutting position. At this time, the abutting member 24 abuts against the narrower end (ie, the tapered tip) of the contact member 222 .

[0038] The embodiment of the present invention utilizes abutment members to abut against the side walls and contact members of the limit rail respectively. When the slider moves, the abutment members move relative to the slider in the direction of the track, compressing the contact members, so that the force of the contact members is converted into resistance during the movement of the slider from the first position to the second position, thereby playing a damping role. At the same time, it avoids the use of long cylinders, reduces the space required for the damping member, and enables the linear push damping slide rail to be further reduced in size, thereby achieving a space-saving effect.

[0039] In particular, such as Figure 1-7 As shown, the abutment member 24 is cylindrical.

[0040] One end of the abutting member 24 is slidably connected to the abutting groove 11 .

[0041] In particular, such as Figure 7 As shown, a conical clamping piece 2222 is provided on one side of the contact member 222 , and a conical clamping groove 2333 is provided on the slider 23 . When the slider 23 is located at the second position, the conical clamping piece 2222 is engaged with the conical clamping groove 2333 .

[0042] Among them, such as Figure 7 As shown, a conical slot 2333 is provided on one side of the slider 23. When the slider 23 slides to the second position, the conical clamping member 2222 slides relative to the conical slot 2333 and engages with each other to ensure that the slider 23 does not slide excessively.

[0043] Optional, such as Figure 2 As shown, there are two tension members 21 , and the two tension members 21 are respectively connected to the two sides of the slider 23 close to the track 1 .

[0044] The tension member 21 is a spring.

[0045] The embodiment of the present invention uses two tension members to balance the tension on the slider, ensuring that the slider can slide smoothly.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that after reading the specification of this application, technicians can still modify or replace the specific implementation methods of the present invention with equivalents, but these modifications or changes do not depart from the scope of protection of the pending claims of the present application.
