Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The present invention provides a drawer slide rail, a cabinet door assembly and a disinfection cabinet. A plurality of embodiments are given below to describe in detail the drawer slide rail, the cabinet door assembly and the disinfection cabinet provided by the present invention.

[0037] Example 1

[0038] The drawer slide provided in this embodiment is as follows: Figures 1 to 9 As shown, it includes a front roller 1, a static slide rail 2 and a movable slide rail assembly 3; the front roller 1 and the static slide rail 2 are used to be arranged at intervals on the mounting surface; the movable slide rail assembly 3 includes a movable slide rail 31, and the movable slide rail 31 is used to connect with the drawer door 4; the movable slide rail 31 has a first surface and a second surface that are arranged oppositely; a first slide groove 21 is provided on the static slide rail 2, and the first surface is rollingly connected to the first slide groove 21 through a rolling member 7; the second surface is arranged on the front roller 1.

[0039] The front roller 1 and the static slide rail 2 cooperate to support the movable slide rail 31. When the movable slide rail 31 is pulled and drawn, the front roller 1 can rotate around its own axis to enable the movable slide rail 31 to achieve a pulling and drawing action. In the pulling and drawing process of the movable slide rail 31, the first slide groove 21 guides the movable slide rail 31 to make the movable slide rail 31 slide along the extension direction of the first slide groove 21, thereby reducing the swing amplitude of the movable slide rail 31 when pulling and drawing, and the load-bearing force deformation is small, which reduces the probability of unsmooth pulling and drawing, blockage of the movable slide rail 31, and jamming. In addition, the rolling element 7 and the front roller 1 are set to roll in different tracks, and do not have a common track space to reduce the width of the track. This can improve the strength of the track component, is easy to manufacture, and can also improve the flexibility and reliability of the drawer slide.

[0040] Among them, the front roller 1 and the static slide rail 2 are arranged at intervals on the mounting surface, the static slide rail 2 needs to be fixed on the mounting surface, the static slide rail 2 can be installed on the mounting surface by fasteners, and can also be welded or bonded to the mounting surface; the front roller 1 needs to be rotatably connected to the mounting surface so that the front roller 1 can rotate around the axis of the front roller 1, and the front roller 1 can be installed on the mounting surface by fasteners.

[0041] In this embodiment, the fasteners pass through the front roller 1, the inner tank side wall and the wall panel 9 in sequence, so that the front roller 1 is installed on the inner tank side wall; the fasteners pass through the static slide rail 2, the inner tank side wall and the wall panel 9 in sequence, so that the static slide rail 2 is installed on the inner tank side wall.

[0042] It should be noted that the mounting surface may be the side wall of the inner tank of a disinfection cabinet, or the side wall of the inner tank of a freezer, or any other suitable mounting surface.

[0043] The front roller 1 and the static slide rail 2 can be connected to the mounting surface separately, or the front roller 1 and the static slide rail 2 can be installed on a mounting member, and then the mounting member is connected to the mounting surface.

[0044] The first surface of the movable slide rail 31 is rollingly connected to the first slide groove 21 through the rolling element 7, and the rolling element 7 can reduce the friction between the first surface and the first slide groove 21, making the pulling smoother. Among them, the rolling element 7 can be set on the movable slide rail 31, and can also be set in the first slide groove 21.

[0045] As an optional implementation, the rolling member 7 is rotatably connected to the movable slide rail 31 , and the rolling member 7 is located at an end of the movable slide rail 31 away from the drawer door 4 ; the rolling member 7 protrudes from the first surface, and the rolling member 7 extends into the first slide groove 21 .

[0046] Specifically, a groove is provided on the first surface, and the rolling member 7 is arranged in the groove and is rotatably connected to the groove. The part of the rolling member 7 protruding from the first surface extends into the first slide groove 21, so that the movable slide rail 31 can slide along the extension direction of the first slide groove 21. The first surface is spaced apart from the static slide rail 2 to avoid surface contact causing poor pulling and pulling action.

[0047] The rolling member 7 is located at one end of the movable slide rail 31 away from the drawer door 4 , so that the rolling member 7 can always slide along the first slide groove 21 during the process of drawing the drawer door 4 .

[0048] Furthermore, the drawer slide rail further comprises a stopper 6 ; the stopper 6 is fixedly connected to one end of the static slide rail 2 facing the drawer door 4 , and the stopper 6 can prevent the rolling member 7 from sliding out of the first slide groove 21 .

When the movable slide rail 31 is pulled out, the front roller 1 slides along the extension direction of the second slide groove 311, which can further limit the movable slide rail 31 to reduce the swing of the movable slide rail 31, thereby improving the flexibility and reliability of the drawer slide rail. In addition, the front roller 1 is arranged in the second slide groove 311, which can prevent the front roller 1 from being separated from the movable slide rail 31, thereby improving the reliability of use.

[0060] Furthermore, the movable slide rail assembly 3 further includes a cross member 32 ; both ends of the cross member 32 are respectively fixedly connected to one end of the movable slide rail 31 away from the drawer door 4 .

[0061] Specifically, the slide rail assembly includes a cross member 32 and two movable slide rails 31. The two ends of the cross member 32 are respectively connected to the two movable slide rails 31 in a one-to-one correspondence. The movable slide rail assembly 3 formed by the cross member 32 and the movable slide rails 31 is used to fix the drawer door 4 and can also be used for placing shelves.

[0062] When the cross member 32 is assembled with the movable slide rail 31 , in order to allow the front roller 1 to be inserted into the second slide groove 311 , the assembly position of the cross member 32 and the movable slide rail 31 can avoid the opening of the second slide rail.
