Slide rail device

Abstract

A sliding rail device comprises a first rail, a second rail and two supporting pieces. The first rail comprises a first bottom wall and two first side walls transversely extending from the side edge of the first bottom wall. The first bottom wall and the first side wall define a first channel, and the first bottom wall forms two mounting grooves which are spaced from each other up and down. The second rail is movably arranged in the first channel and comprises a second bottom wall and two second side walls transversely extending from the side edge of the second bottom wall. The supporting pieces are movably arranged in the mounting grooves respectively and abut against the first side wall and the second side wall, and when the second rail moves relative to the first rail, the supporting pieces move along the mounting grooves respectively so as to abut against the second side wall more tightly.

Description

Technical Field

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

[0002] The existing support structure is to fix the support assembly on the groove of the first slide rail, and ensure that the second slide rail can be kept on the track of the first slide rail through the support assembly. The disadvantage of this method is that it is not easy to install using a fixed installation method, and it is impossible to completely fit the second slide rail, so that the second slide rail cannot slide stably in the track of the first slide rail. Therefore, there is still room for improvement. Summary of the invention

[0003] An object of the present invention is to provide a slide rail device that can solve at least one of the above problems.

[0004] The slide rail device described in the present invention includes a first rail, including a first bottom wall and two first side walls extending laterally from the side edges of the first bottom wall, the first bottom wall and the first side walls define a first channel, and the first bottom wall forms two mounting grooves spaced apart from each other up and down; a second rail, movably arranged in the first channel, and including a second bottom wall and two second side walls extending laterally from the side edges of the second bottom wall; and two support members, respectively movably arranged in the mounting grooves and abutting against the first side wall and the second side wall, when the second rail moves relative to the first rail, the support members respectively move along the mounting grooves to more tightly abut against the second side wall.

[0005] In some embodiments, each of the mounting grooves has a mounting bevel, and each of the support members includes a main body extending along the length direction of the first rail and respectively abutting against the first side wall and the second side wall, and a block protruding from the main body toward the first bottom wall and extending into the mounting groove, and the block forms an engaging bevel toward one end of the mounting bevel. When the second rail moves relative to the first rail, the engaging bevel can abut against the mounting bevel, so that the support member will move toward the second rail to more tightly abut against the second side wall.

[0006] In some implementations, each of the mounting grooves is in the shape of a parallelogram.

[0007] In some implementations, the portion of each of the blocks extending into the mounting slot is in the shape of a parallelogram.

[0008] The beneficial effect of the present invention is that by the support members being movably arranged in the installation groove and abutting against the second side wall, the support members can be more easily installed in the installation groove and the support members can be completely close to the second side wall, so that the second rail can move stably in the first channel.

[0019] See also Figures 1 to 3 The embodiment of the slide rail device 100 of the present invention comprises a first rail 1, a second rail 2, two support members 3 and two ball bearing bars 4.

[0020] The first rail 1 includes a first bottom wall 11 and two first side walls 12 extending transversely from the side edge of the first bottom wall 11. The first bottom wall 11 and the first side walls 12 define a first channel 13, and each of the first bottom walls 11 forms two mounting grooves 111 spaced apart from each other up and down, and the mounting grooves 111 are adjacent to one end of the first bottom wall 11. The second rail 2 is movably disposed in the first channel 13, and includes a second bottom wall 21 and two second side walls 22 extending transversely from the side edge of the second bottom wall 21. Each of the mounting grooves 111 is parallelogram-shaped and has a mounting slope 112, which extends obliquely from the first side wall 12 toward the second side wall 22 and away from the ball bar 4.

[0021] See also Figures 4 to 6 The support members 3 are movably disposed in the mounting grooves 111 and abut against the first side wall 12 and the second side wall 22. When the second rail 2 moves relative to the first rail, the support members 3 move along the mounting grooves 111 to abut against the second side wall 22. Each of the support members 3 includes a body 31 extending along the length direction of the first rail 1 and abutting against the corresponding first side wall 12 and the corresponding second side wall 22, and a block 32 protruding from the body 31 toward the corresponding first side wall 12 and extending into the mounting groove 111. The portion of the block 32 of each support member 3 extending into the corresponding mounting groove 111 is in the shape of a parallelogram. An end of the block 32 facing the mounting inclined surface 112 forms a snap-fitting inclined surface 321, which can abut against the mounting inclined surface 112, so that the support member 3 will move toward the second rail 2 to abut against the second side wall 22. The ball bearing bars 4 are movably disposed on the first side walls 12 and abut against the second side walls 22 .

[0022] See also Figure 1 , Figure 2 The slide rail device 100 of the present invention can be transformed between a retracted state and an extended state. In the retracted state, the second rail 2 is located in the first channel 13 and substantially overlaps with the first rail 1, the support members 3 are respectively located at one end of the mounting groove 111, and the ball bar and the support member 3 are spaced apart from each other. Figure 1 , Figure 6 and Figure 7 Then refer to Figure 8 and Fig. 9When the second rail 2 moves along the first channel 13 and extends relative to the first rail 1 to finally reach the extended state, the ball bar 4 moves along with the second rail 2 and respectively abuts against the support member 3 and then pushes the support member 3 to the other end of the mounting groove 111. Through the cooperation of the engaging inclined surface 321 and the mounting inclined surface 112, the engaging inclined surface 321 abuts against the mounting inclined surface 112 to cause the support member 3 to move slightly toward the second side wall 22, so that the support member 3 can be completely close to the second side wall 22 and the first side wall 12, which can suppress the shaking and rotation of the second rail 2 when it is extended relative to the first rail 1, so that the second rail 2 can stably move in the first channel 13, and the slide rail device 100 can be more stable and not easily affected by external forces when it is converted from the retracted state to the extended state.

[0023] In summary, the slide rail device 100 of the present invention can more easily install the support member 3 in the installation groove 111 by virtue of the support member 3 being movably disposed in the installation groove 111 and abutting against the second side wall 22. Furthermore, by virtue of the cooperation between the engaging inclined surface 321 and the installation inclined surface 112, when the second rail 2 moves relative to the first rail 1 to the extended state, the support member 3 can move toward the second side wall 22, so that the support member 3 is completely close to the second side wall 22, and the second rail 2 can stably move in the first channel 13, thereby truly achieving the purpose of the present invention.

[0024] The above are merely embodiments of the present invention and should not be used to limit the scope of the present invention. That is, any simple equivalent changes and modifications made according to the claims and description of the present invention still fall within the scope of the present invention.
