The second sub-side wall 123 is arranged opposite to the bottom wall 11. The bottom wall 11, the first sub-side wall 121, and the second sub-side wall 123 form a slide groove, which is used for the main body 301 to cooperate, so that the main body 301 can slide along the slide groove. At the same time, part of the structure of the main body 301 is located between the second sub-side wall 123 and the first sub-side wall 121. The second sub-side wall 123 and the first sub-side wall 121 can limit the main body 301, so that the main body 301 can better slide along the slide groove in the sliding cavity 100. In this embodiment, the slide groove is a part of the sliding cavity 100, which is used to limit the main body located in the sliding cavity 100, so that the main body 301 slides along the direction defined by the slide groove.

In other embodiments, the minimum distance between the second surface 3012 and the bottom wall 11 can be equal to the minimum distance between the reinforcing rib assembly and the bottom wall, and the structure between the male slide rail and the female slide rail 10 is compact.

[0044] Please combine Figure 6 , Figure 7 In some embodiments, the female slide rail 10 further includes a second limiting wall 17, which is installed between the first side wall 12 and the second side wall 13, and the second limiting wall 17 is connected to the bottom wall 11. The sliding cavity 100 is provided with a first opening 103 arranged opposite to the second limiting wall. The male slide rail 30 is installed to the sliding cavity 100 from the first opening 103 and can slide along the sliding cavity 100. When sliding to the second limiting wall 17, the second limiting wall 17 can prevent the male slide rail 30 from continuing to slide.

The diameter of the second opening 1103 gradually increases along the axial direction of the first opening 1101 and in a direction away from the first opening 1101.

[0047] The slide rail structure in the embodiment of the present application can be used for furniture, wherein the male slide rail can be used to fix the connection with the cabinet body, such as screw connection, riveting, etc.; the female slide rail can be used to fix the connection with the inner wall of the cabinet, such as screw connection, riveting, etc.; when the female slide rail is fixed to the inner wall of the cabinet with a bolt, generally one end of the screw rod of the bolt is passed through the opening on the bottom wall of the female slide rail and then fixed to the inner wall of the cabinet, at this time, the screw head part of the bolt will be located on the side of the bottom wall of the female slide rail facing the male slide rail. In order to prevent the screw head part of the bolt from hindering the movement of the male slide rail, please combine Figure 7 In some embodiments, a stepped hole 110 penetrating the bottom wall 11 is provided on the bottom wall 11, and a second opening 1103 is provided on the side of the bottom wall 11 facing the sliding cavity. The diameter of the second opening 1103 gradually increases along the axial direction of the first opening and in a direction away from the first opening 1101. In this way, one end of the screw rod of the bolt successively passes through the second opening 1103 and the first opening 1101 on the bottom wall of the female slide rail and is then fixed to the inner wall of the cabinet. The screw head portion of the bolt will be located in the second opening 1103, so that the screw head portion of the bolt can be flush with the surface of the bottom wall 11 facing the sliding cavity, or more concave relative to the surface of the bottom wall 11 facing the sliding cavity, thereby effectively avoiding the screw head portion of the bolt from protruding and interfering with the male slide rail 30, causing the problem of poor movement of the slide rail structure.

[0048] Furthermore, since the stepped hole 110 and the groove 303 are arranged relative to each other, combined with the above-mentioned scheme, the minimum distance between the main body 301 and the bottom wall 11 is configured to be less than or equal to the minimum distance between the reinforcing rib assembly and the bottom wall, and the minimum distance between the second surface 3012 and the bottom wall 11 is less than or equal to the minimum distance between the reinforcing rib assembly and the bottom wall, so that the reinforcing rib assembly in the groove 303 is not easy to interfere with the screw head part of the bolt, so that the slide rail moves more smoothly, bringing users a better use experience.
