Description

Technical Field

[0001] This utility model relates to a slide rail device, and more particularly to a slide rail device with a support member. Background Technology

[0002] The existing support structure involves fixing the support assembly to the groove of the first slide rail, using the support assembly to ensure that the second slide rail remains on the track of the first slide rail. The disadvantage of this approach is that the fixed installation method is difficult to implement, and it cannot completely fit the second slide rail, preventing the second slide rail from sliding stably within the track of the first slide rail. Therefore, there is room for improvement. Summary of the Invention

[0003] The purpose of this invention is to provide a slide rail device that can solve at least one of the above-mentioned problems.

[0004] The slide rail device of this utility model includes a first rail, comprising a first bottom wall and two first side walls extending laterally from the side edge of the first bottom wall, the first bottom wall and the first side walls defining a first channel, each of the first side walls having a mounting groove; a second rail, movably disposed in the first channel, and comprising a second bottom wall and two second side walls extending laterally from the side edge of the second bottom wall; and two support members, respectively movably disposed in the mounting groove and abutting against the second side walls, wherein when the second rail moves relative to the first rail, the support members move along the mounting groove to abut against the second side walls more tightly.

[0005] In some embodiments, two ball bearings are movably disposed on the first sidewall and abutting against the second sidewall. Each ball bearing has a ball bearing ramp, and each support has a first support ramp. When the second rail moves relative to the first rail, the ball bearing ramps of the ball bearings abut against the first support ramps of the support, thereby pushing the support along the mounting groove and making the support more tightly against the second sidewall.

[0006] In some embodiments, each support member also has a second support ramp that abuts against the corresponding first sidewall and extends obliquely toward the second rail. When the support member is pushed along the mounting groove, the support member will displace toward the second rail to abut more closely against the second sidewall.

[0007] In some embodiments, each of the support members includes a body extending along the length of the first rail and abutting against the corresponding first sidewall and the corresponding second sidewall, and a locking block protruding from the body toward the first sidewall and extending into the mounting groove. The end of the body facing the ball strip forms the first support slope, and the second support slope extends obliquely toward the second rail from the connection between the locking block and the body and away from the first support slope.

[0008] The beneficial effects of this utility model are as follows: by having the support members movably disposed in the mounting groove and abutting against the second side wall, the support members can be more easily installed in the mounting groove and the support members can be completely and tightly attached to the second side wall, so that the second rail can move stably in the first channel.

[0019] See Figures 1 to 3 An embodiment of the slide rail device 100 of this utility model includes a first rail 1, a second rail 2, two support members 3 and two ball bearings 4.

[0020] The first track 1 includes a first bottom wall 11 and two first side walls 12 extending laterally from the side edges 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 side walls 12 has a mounting groove 121 adjacent to one end of the first side wall 12. The second track 2 is movably disposed in the first channel 13 and includes a second bottom wall 21 and two second side walls 22 extending laterally from the side edges of the second bottom wall 21.

[0021] See Figures 4 to 6 Each support member 3 is movably disposed in the mounting groove 121 and abuts against the second sidewall 22. When the second rail 2 moves relative to the first rail 1, the support member 3 moves along the mounting groove 121 to abut more tightly against the second sidewall 22. Each support member 3 includes a body 31 extending along the length direction of the first rail 1 and abutting against the corresponding first sidewall 12 and the corresponding second sidewall 22, and a locking block 32 protruding from the body 31 toward the corresponding first sidewall 12 and extending into the mounting groove 121. The end of the body 31 of each support member 3 facing the corresponding ball bearing 4 forms a first supporting slope 311, and has a second supporting slope 312 extending obliquely toward the second rail 2 and away from the first supporting slope 311 from the connection between the locking block 32 and the body 31. The first supporting slope 311 extends obliquely from the first sidewall 12 toward the second sidewall 22. The ball bearings 4 are movably disposed on the first sidewall 12 and abut against the second sidewall 22. Each ball bearing 4 has a ball bearing inclined surface 41, which cooperates with the corresponding first support inclined surface 311 and extends obliquely from the second sidewall 22 toward the first sidewall 12.

[0022] See Figure 1 , Figure 2 The slide rail device 100 of this utility model can switch between a retracted state and an extended state. In the retracted state, the second rail 2 is located within the first channel 13 and approximately overlaps with the first rail 1. The support members 3 are respectively located at one end of the mounting groove 121, and the ball bearings 4 are spaced apart from the support members 3. Figure 1 , Figure 6 and Figure 7 As shown. See also the accompanying references. Figure 8 and Figure 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 bearing 4 moves with the second rail 2 and abuts against the support member 3 respectively, and then pushes the support member 3 to the other end of the mounting groove 121. First, through the cooperation of the first support inclined surface 311 and the ball bearing inclined surface 41, the support member 3 will also move slightly towards the second side wall 22 during the process of being pushed. Then, through the cooperation of the second support inclined surface 312 and the first side wall 12, when the second support inclined surface 312 abuts against the first side wall 12, the support member 3 will also move slightly towards the second side wall 22. In this way, the support member 3 can completely fit against the second side wall 22 and the first side wall 12, which can suppress the shaking and rotation caused when the second rail 2 extends relative to the first rail 1, so that the second rail 2 can move stably in the first channel 13. When the slide rail device 100 changes from the retracted state to the extended state, it can be more stable and less susceptible to external interference.

[0023] In summary, the slide rail device 100 of this utility model, by means of the support members 3 being movably disposed in the mounting groove 121 and abutting against the second side wall 22, makes it easier to install the support members 3 in the mounting groove 121. Furthermore, by means of the cooperation between the first support inclined surface 311 and the ball inclined surface 41, and the cooperation between the second support inclined surface 312 and the first side wall 12, when the second rail 2 moves to the extended state relative to the first rail 1, the support member 3 can move towards the second side wall 22, so that the support member 3 is completely pressed against the second side wall 22, and the second rail 2 can move stably in the first channel 13, thus effectively achieving the purpose of this utility model.

[0024] The above description is merely an embodiment of this utility model and should not be construed as limiting the scope of this utility model. Any simple equivalent changes and modifications made in accordance with the claims and description of this utility model shall still fall within the scope of this utility model.
