[0037] Combine the following Figure 1-Figure 6 The rail holding device 10 and the mother rail installation tool 100 having the same according to an embodiment of the present utility model are described in detail.

[0038] Reference Figure 1-Figure 3 As shown, according to the rail holding device 10 of the embodiment of the utility model, it includes: a mounting assembly 1, a driving assembly 2 and a clamping assembly 3, the mounting assembly 1 includes a mounting seat 11 and a first pin shaft 12 and a second pin shaft 13 mounted on the mounting seat 11, the clamping assembly 3 includes a first clamping jaw 31 and a second clamping jaw 32 that are arranged opposite to each other and spaced apart, the first clamping jaw 31 has a first guide hole 3121, the second clamping jaw 32 has a second guide hole 3221, the spacing between the first guide hole 3121 and the second guide hole 3221 gradually increases from bottom to top, and the first guide hole 3121 is arranged at a distance from the first guide hole 3121 to the second guide hole 3221. The guide hole 3121 is movably sleeved on the first pin shaft 12, and the second guide hole 3221 is movably sleeved on the second pin shaft 13. The driving assembly 2 includes a connected driving member 21 and a transmission member 22. The first clamping jaw 31 and the second clamping jaw 32 are both rotatably connected to the transmission member 22. The driving member 21 is used to drive the transmission member 22 to move up and down. When the driving member 21 drives the transmission member 22 to move up and down, the transmission member 22 can drive one end of the first clamping jaw 31 and one end of the second clamping jaw 32 to move away from or close to each other, so that the clamping assembly 3 is opened or clamped. Among them, the driving member 21 can be a cylinder, and the driving member 21 can include a cylinder body and a push rod movably connected to the cylinder body. The cylinder body can be fixedly connected to the mounting seat 11, and the push rod is suitable for connecting with the transmission member 22. The push rod can drive the transmission member 22 to move up and down by moving up and down.

[0039] It can be understood that the first guide hole 3121 can be movably mounted on the first pin shaft 12 to achieve guiding cooperation between the first guide hole 3121 and the first pin shaft 12, and the second guide hole 3221 can be movably mounted on the second pin shaft 13 to achieve guiding cooperation between the second guide hole 3221 and the second pin shaft 13.

[0040] When the driving member 21 drives the transmission member 22 to move upward, the transmission member 22 can drive the first clamping jaw 31 and the second clamping jaw 32 to move upward. Since the distance between the first guide hole 3121 and the second guide hole 3221 gradually increases from bottom to top, under the guidance cooperation between the first guide hole 3121 and the first pin shaft 12, and under the guidance cooperation between the second guide hole 3221 and the second pin shaft 13, the first clamping jaw 31 moves counterclockwise ( Figure 1 The second clamping jaw 32 rotates clockwise relative to the transmission member 22 ( Figure 1 The first clamping jaw 31 and the second clamping jaw 32 rotate in the direction b), and the ends away from the transmission member 22 of the first clamping jaw 31 and the second clamping jaw 32 move away from each other, so that the clamping assembly 3 is opened.

[0041] When the driving member 21 drives the transmission member 22 to move downward, the transmission member 22 can drive the first clamping jaw 31 and the second clamping jaw 32 to move downward. Since the distance between the first guide hole 3121 and the second guide hole 3221 gradually decreases from top to bottom, under the guidance cooperation between the first guide hole 3121 and the first pin shaft 12, and under the guidance cooperation between the second guide hole 3221 and the second pin shaft 13, the first clamping jaw 31 moves clockwise ( Figure 1 c direction), the second clamping jaw 32 rotates counterclockwise ( Figure 1 The first clamping jaw 31 and the second clamping jaw 32 rotate in the direction (in the middle d direction), and the ends away from the transmission member 22 of the first clamping jaw 31 and the second clamping jaw 32 approach each other to clamp the clamping assembly 3.

[0042] The guiding cooperation between the first guide hole 3121 and the first pin shaft 12, and the guiding cooperation between the second guide hole 3221 and the second pin shaft 13, can help improve the stability of the movement of the first clamping jaw 31 and the second clamping jaw 32, and can effectively reduce the risk of jamming when the first clamping jaw 31 and the second clamping jaw 32 move, thereby helping to improve the smoothness of opening or clamping the clamping assembly 3.

[0043] The rail holding device 10 can fix the mother rail in the slide rail assembly before installing the seat adjustment handle to prevent the mother rail from moving, so as to facilitate sliding at least a portion of the male rail in the slide rail assembly to the front end of the mother rail, which is beneficial to the assembly of the seat adjustment handle. Specifically, the mounting seat 11 is suitable for supporting the mother rail. Before the seat adjustment handle is assembled, the driving member 21 drives the transmission member 22 to move upward so that the first clamping jaw 31 and the second clamping jaw 32 are away from one end of the transmission member 22 and move away from each other. When the mother rail is placed on the mounting seat 11, the risk of interference between the mother rail and the first clamping jaw 31 and the second clamping jaw 32 respectively can be reduced, which is beneficial to placing the mother rail in a preset position. After the mother rail is placed in the preset position, the driving member 21 drives the transmission member 22 to move downward so that the first clamping jaw 31 and the second clamping jaw 32 are away from one end of the transmission member 22 and move close to each other and clamp the mother rail together, so that the position of the mother rail remains fixed, which is beneficial to the assembly of the seat adjustment handle.

[0044] According to the rail holding device 10 of the utility model embodiment, the first guide hole 3121 of the first clamping jaw 31 can be movably mounted on the first pin shaft 12, and the second guide hole 3221 of the second clamping jaw 32 can be movably mounted on the second pin shaft 13. The spacing between the first guide hole 3121 and the second guide hole 3221 gradually increases from bottom to top. The first clamping jaw 31 and the second clamping jaw 32 are both rotatably connected to the transmission member 22. The driving member 21 can drive the first clamping jaw 31 and the second clamping jaw 32 to rotate while moving up and down through the transmission member 22 to realize the opening and clamping of the clamping assembly 3. The structure of the rail holding device 10 is simple and reliable, and the opening and clamping movements of the clamping assembly 3 are smooth and stable.

[0045] In some embodiments of the present invention, referring to Figure 2 and Figure 3 As shown, the first clamping jaw 31 includes: a first clamping portion 311, a first guide portion 312 and a first connecting portion 313, the first guide portion 312 is connected between the first clamping portion 311 and the first connecting portion 313, the first guide portion 312 has a first guide hole 3121, and the first connecting portion 313 is rotatably connected to the transmission member 22, so that the first clamping jaw 31 and the transmission member 22 can be rotatably connected, and the second clamping jaw 32 includes: a second clamping portion 321, a second guide portion 322 and a second connecting portion 323, the second guide portion 322 is connected between the second clamping portion 321 and the second connecting portion 323, the second guide portion 322 has a second guide hole 3221, and the second connecting portion 323 is rotatably connected to the transmission member 22, so that the second clamping jaw 32 and the transmission member 22 can be rotatably connected.

[0046] It can be understood that the first guide portion 312 is connected between the first clamping portion 311 and the first connecting portion 313, and the first clamping portion 311 can be located at the upper portion of the first clamping jaw 31, and the second guide portion 322 is connected between the second clamping portion 321 and the second connecting portion 323, and the second clamping portion 321 can be located at the upper portion of the second clamping jaw 32. The mother rail is clamped by the upper portion of the first clamping jaw 31 and the upper portion of the second clamping jaw 32, and the operating space is larger, which is convenient for clamping the mother rail.

[0047] Reference Figure 1 As shown, the transmission member 22 may include a connecting block 221 and a third pin shaft 222 and a fourth pin shaft 223 installed on the connecting block 221. The first connecting portion 313 of the first clamping jaw 31 is sleeved on the third pin shaft 222 and is rotatably connected to the third pin shaft 222, so that the first clamping jaw 31 can be rotatably connected to the transmission member 22. The second connecting portion 323 of the second clamping jaw 32 is sleeved on the fourth pin shaft 223 and is rotatably connected to the fourth pin shaft 223, so that the second clamping jaw 32 can be rotatably connected to the transmission member 22. The driving member 21 is connected to the connecting block 221, wherein the first pin shaft 12, the second pin shaft 13, the third pin shaft 222 and the fourth pin shaft 223 can all be hinge pins, and the axis of the first pin shaft 12, the axis of the second pin shaft 13, the axis of the third pin shaft 222 and the axis of the fourth pin shaft 223 are parallel to each other.

[0048] When the driving member 21 drives the connecting block 221 to move upward, the connecting block 221 drives the first clamping jaw 31 and the second clamping jaw 32 to move upward. Since the spacing between the first guide hole 3121 and the second guide hole 3221 gradually increases from bottom to top, and under the guiding cooperation between the first guide hole 3121 and the first pin shaft 12, and the guiding cooperation between the second guide hole 3221 and the second pin shaft 13, the first connecting portion 313 of the first clamping jaw 31 rotates counterclockwise around the third pin shaft 222, and the second connecting portion 323 of the second clamping jaw 32 rotates clockwise around the fourth pin shaft 223. The first clamping portion 311 of the first clamping jaw 31 and the second clamping portion 321 of the second clamping jaw 32 move in a direction away from each other to open the clamping assembly 3. When the mother rail is placed on the mounting seat 11, the risk of interference between the mother rail and the first clamping jaw 31 and the second clamping jaw 32, respectively, can be reduced, so that the mother rail can be placed in a preset position.

[0049] When the driving member 21 drives the connecting block 221 to move downward, the connecting block 221 drives the first clamping jaw 31 and the second clamping jaw 32 to move downward. Since the distance between the first guide hole 3121 and the second guide hole 3221 gradually increases from bottom to top, and under the guiding cooperation between the first guide hole 3121 and the first pin shaft 12, and the guiding cooperation between the second guide hole 3221 and the second pin shaft 13, the first connecting portion 313 of the first clamping jaw 31 rotates clockwise around the third pin shaft 222, and the second connecting portion 323 of the second clamping jaw 32 rotates counterclockwise around the fourth axis, and the first clamping portion 311 of the first clamping jaw 31 and the second clamping portion 321 of the second clamping jaw 32 move in a direction approaching each other, so that the first clamping jaw 31 and the second clamping jaw 32 clamp the mother rail together.

[0050] In some embodiments of the utility model, the first clamping portion 311 has a first clamping side surface 31121 and a first clamping top surface 31122 located above the first clamping side surface 31121, and the second clamping portion 321 has a second clamping side surface 32121 and a second clamping top surface 32122 located above the second clamping side surface 32121. The first clamping side surface 31121 and the second clamping side surface 32121 are arranged opposite to each other, and the first clamping top surface 31122 and the second clamping top surface 32122 extend in a direction approaching each other, which is beneficial to increase the contact area between the first clamping portion 311 and the mother rail, and increase the contact area between the second clamping portion 321 and the mother rail, thereby facilitating improving the stability and reliability of the first clamping portion 311 and the second clamping portion 321 in clamping the mother rail.

[0051] It can be understood that when the clamping assembly 3 clamps the mother rail, the first clamping side surface 31121 and the second clamping side surface 32121 can respectively clamp the left and right sides of the mother rail to limit the mother rail in the left and right directions. At the same time, the first clamping top surface 31122 and the second clamping top surface 32122 can jointly press against the top surface of the mother rail to make the bottom surface of the mother rail fit with the mounting seat 11, thereby limiting the mother rail in the up and down directions. In addition, referring to Figure 1 As shown, a positioning pin 113 is provided on the top of the mounting seat 11, and the positioning pin 113 is suitable for positioning and cooperating with the positioning hole on the mother rail to limit the mother rail in the front-rear direction to avoid the mother rail from shaking, which is convenient for the assembly of the seat adjustment handle.

[0052] In some embodiments of the present invention, referring to Figure 1-Figure 5As shown, the first clamping part 311 includes: a first clamping body 3111 and a first cushion block 3112, the first clamping body 3111 is connected to the first guide part 312, the first cushion block 3112 is detachably connected to the first clamping body 3111, and the first cushion block 3112 has a first clamping side surface 31121 and a first clamping top surface 31122, and the second clamping part 321 includes: a second clamping body 3211 and a second cushion block 3212, the second clamping body 3211 is connected to the second guide part 322, the second cushion block 3212 is detachably connected to the second clamping body 3211, and the second cushion block 3212 has a There are a second clamping side surface 32121 and a second clamping top surface 32122. When the first cushion block 3112 and the second cushion block 3212 are damaged, the first cushion block 3112 can be removed from the first clamping body 3111, the second cushion block 3212 can be removed from the second clamping body 3211, and a new first cushion block 3112 can be installed to the first clamping body 3111, and a new second cushion block 3212 can be installed to the second clamping body 3211, so as to replace the first cushion block 3112 and the second cushion block 3212, thereby eliminating the need to replace the first clamping jaw 31 and the second clamping jaw 32 as a whole, which is conducive to saving the maintenance cost of the clamping assembly 3. Among them, the first cushion block 3112 and the first clamping body 3111 can be detachably connected by a first fastener, and the second cushion block 3212 and the second clamping body 3211 can be detachably connected by a second fastener, and the first cushion block 3112 and the second cushion block 3212 can both be L-shaped structural blocks.

[0053] Specifically, the first fastener and the second fastener may both be screws, the first clamping body 3111 may have a first connecting hole, the first cushion block 3112 may have a second connecting hole, the second clamping body 3211 may have a third connecting hole, the second cushion block 3212 may have a fourth connecting hole, the first connecting hole and the third connecting hole may be threaded holes, the second connecting hole and the fourth connecting hole may be through holes, the first fastener may be inserted into the second connecting hole and threadedly matched with the first connecting hole, so that the first cushion block 3112 is installed on the first clamping body 3111 11. The first cushion block 3112 can be removed from the first clamping body 3111 by loosening the first fastener, and the second fastener can be inserted into the fourth connecting hole and threadedly engaged with the third connecting hole to install the second cushion block 3212 on the second clamping body 3211. The second cushion block 3212 can be removed from the second clamping body 3211 by loosening the second fastener. The installation and disassembly operations of the first cushion block 3112 and the second cushion block 3212 are relatively simple, which is conducive to improving the convenience of replacing the first cushion block 3112 and the second cushion block 3212.

[0054] In some embodiments of the utility model, the first pad 3112 and the second pad 3212 may have a variety of specifications. By replacing the first pad 3112 and the second pad 3212 of different specifications, the distance between the first clamping side surface 31121 and the second clamping side surface 32121 can be adjusted, and the distance between the first clamping top surface 31122 and the top surface of the mounting seat 11 and the distance between the second clamping top surface 32122 and the top surface of the mounting seat 11 can also be adjusted, thereby adjusting the clamping force applied by the first clamp 31 and the second clamp 32 to the mother rail. In addition, by replacing the first pad 3112 and the second pad 3212 of different specifications, the first clamp 31 and the second clamp 32 can also be adapted to mother rails of different models, which is conducive to improving the versatility of the rail holding device 10.

[0055] In some embodiments of the present invention, the first pad 3112 and the second pad 3212 are both made of nylon. The hardness of the first pad 3112 and the second pad 3212 made of nylon is relatively soft, so that when the first pad 3112 and the second pad 3212 clamp the mother rail, the wear of the mother rail is reduced, thereby helping to reduce the risk of damage to the mother rail. In addition, the price of the first pad 3112 and the second pad 3212 made of nylon is cheap. When the first pad 3112 or the second pad 3212 is damaged, the cost of maintaining the clamping assembly 3 by replacing the first pad 3112 or the second pad 3212 is low.

[0056] In some embodiments of the present invention, referring to Figure 2 and Figure 3 As shown, the first guide hole 3121 and the second guide hole 3221 are both constructed as oblong holes. When the first pin shaft 12 is located at the end of the first guide hole 3121 and the second pin shaft 13 is located at the end of the second guide hole 3221, it is beneficial to increase the contact area between the first pin shaft 12 and the first guide hole 3121, and to increase the contact area between the second pin shaft 13 and the second guide hole 3221, which is beneficial to improve the stability of the movement of the first clamp 31 and the second clamp 32.

The return spring 4 can always apply a pulling force to the first clamp 31 and the second clamp 32 that are away from the transmission member 22, that is, the return spring 4 is always stretched by the first clamp 31 and the second clamp 32, which is conducive to the first clamp 31 and the second clamp 32 clamping the mother rail, and reduces the risk of the first clamp 31 and the second clamp 32 getting stuck during movement. In addition, during the assembly process of the seat adjustment handle, when the drive member 21 fails, the elastic force of the spring can keep the first clamp 31 and the second clamp 32 clamping the mother rail, avoiding the positioning failure of the mother rail.

[0058] Reference Figure 1-Figure 3 As shown, the first clamping jaw 31 has a first mounting hole 314, and the second clamping jaw 32 has a second mounting hole 324. The first mounting hole 314 is suitable for installing the first fixed shaft, and the second mounting hole 324 is suitable for installing the second fixed shaft. One end of the reset spring 4 can be connected to the first fixed shaft, and the other end of the reset spring 4 can be connected to the second fixed shaft, so that the reset spring 4 is connected between the first clamping jaw 31 and the second clamping jaw 32.

[0059] In some embodiments of the utility model, the mounting base 11 has a first guide groove 111 and a second guide groove 112 arranged back to back, the first pin shaft 12 is passed through the two opposite side walls of the first guide groove 111, the first clamping jaw 31 is slidably matched with the two opposite side walls of the first guide groove 111, the second pin shaft 13 is passed through the two opposite side walls of the second guide groove 112, and the second clamping jaw 32 is slidably matched with the two opposite side walls of the second guide groove 112, which is beneficial to improving the stability of the movement of the first clamping jaw 31 and the second clamping jaw 32.

[0060] It can be understood that the first clamping jaw 31 slides with the two side walls opposite to the first guide groove 111, which can avoid the first clamping jaw 31 from tilting relative to the two side walls of the first guide groove 111 during movement, which is beneficial to improving the stability of the movement of the first clamping jaw 31, and the second clamping jaw 32 slides with the two side walls opposite to the second guide groove 112, which can avoid the second clamping jaw 32 from tilting relative to the two side walls of the second guide groove 112 during movement, which is beneficial to improving the stability of the movement of the second clamping jaw 32.

[0061] In some embodiments, the first pin shaft 12 and the second pin shaft 13 are rotatably connected to the mounting base 11. When the first clamping jaw 31 moves, the first pin shaft 12 can roll relative to the first clamping jaw 31, which is beneficial to reduce the friction between the first clamping jaw 31 and the first pin shaft 12, and is beneficial to reduce the wear of the first clamping jaw 31. When the second clamping jaw 32 moves, the second pin shaft 13 can roll relative to the second clamping jaw 32, which is beneficial to reduce the friction between the second clamping jaw 32 and the second pin shaft 13, and is beneficial to reduce the wear of the second clamping jaw 32, thereby facilitating the improvement of the service life of the clamping assembly 3.

[0062] In another embodiment, the first pin shaft 12 and the second pin shaft 13 are both fixedly connected to the mounting base 11, which is beneficial to improving the stability and reliability of the connection between the first pin shaft 12 and the second pin shaft 13 and the mounting base 11, and reducing the risk of vibration of the first pin shaft 12 and the second pin shaft 13, thereby helping to improve the stability of the movement of the first clamp 31 and the second clamp 32.

[0063] Reference Figure 1-Figure 6 As shown, a mother rail installation tool 100 according to another embodiment of the present utility model includes the above-mentioned rail holding device 10.

[0064] According to the mother rail installation tool 100 of the embodiment of the utility model, the first guide hole 3121 of the first clamping jaw 31 can be movably mounted on the first pin shaft 12, and the second guide hole 3221 of the second clamping jaw 32 can be movably mounted on the second pin shaft 13. The spacing between the first guide hole 3121 and the second guide hole 3221 gradually increases from bottom to top. The first clamping jaw 31 and the second clamping jaw 32 are both rotatably connected to the transmission member 22. The driving member 21 can drive the first clamping jaw 31 and the second clamping jaw 32 to rotate while moving up and down through the transmission member 22 to realize the opening and clamping of the clamping assembly 3. The structure of the rail holding device 10 is simple and reliable, and the opening and clamping movements of the clamping assembly 3 are smooth and stable.

[0065] In some embodiments of the present invention, referring to Figure 6 As shown, the mother rail installation tool 100 also includes a mounting frame 20 , and the mounting frame 20 has a base plate 201 . The rail holding device 10 is installed above the base plate 201 to facilitate the maintenance of the rail holding device 10 .

[0066] It can be understood that the space above the base plate 201 is relatively large. When components in the track holding device 10 need maintenance, the corresponding components can be maintained above the base plate 201 without removing the entire track holding device 10 from the base plate 201, which is conducive to improving the maintenance of the track holding device 10.

[0067] In some embodiments of the present invention, the mother rail installation tool 100 may include four rail holding devices 10, each two rail holding devices 10 are used to support and clamp a mother rail of the seat slide rail assembly, and the two rail holding devices 10 may be spaced apart in the length direction of the mother rail to reliably support the mother rail.
