[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 The utility model provides an implementation scheme: In the application process of modern power distribution cabinets, the power distribution cabinet with 3 distribution drawers has the following problems in the application process: when the drawers on the upper layer of the power distribution cabinet are pulled out, it is difficult for operators to operate due to their high height, and it is easy to cause the drawers to be deformed by force and the power distribution cabinet to fall down during the pulling process.

[0024] In view of the above problems, the present application discloses a drawer structure of a power distribution cabinet, which adopts a rectangular shell power distribution cabinet body 1 made of rolled steel plate, the interior of the power distribution cabinet body 1 is a cavity, and a plurality of pairs of tracks 2 are arranged from top to bottom on both sides of the power distribution cabinet body 1, and the number of pairs of tracks 2 is the same as the number of power distribution drawers 3, and the specific number is set according to the customer's use requirements or the number of electrical appliances, and a plurality of power distribution drawers 3 are assembled on the plurality of pairs of tracks 2, and the power distribution drawers 3 are the container bodies for electrical installation in the power distribution cabinet;

[0025] Specifically, a pair of sliding seats 4 are symmetrically arranged on both sides of the bottom surface of the power distribution drawer 3, and a pair of sliding grooves 5 matching the sliding seats 4 are opened on the pair of rails 2 on the same horizontal plane. The sliding grooves 5 and the pair of sliding seats 4 play a limiting role and support the power distribution drawer 3, thereby reducing the friction during the sliding process of the drawer;

[0026] Furthermore, in order to ensure smoother sliding of the upper drawer when it is pulled out and avoid bending the cabinet body by manual force, a pair of rotating grooves 6 are provided on at least one pair of tracks 2 on the uppermost layer among the plurality of them, and the rotating rod 7 is installed and limited by the rotating grooves 6. A driving gear 8 is sleeved on the rotating rod 7, and a portion of the driving gear 8 protrudes from the side of the track 2. The driving gear 8 can be driven to rotate by the rotating rod 7. Correspondingly, a rack 12 is provided on the bottom surface of the upper power distribution drawer 3 to mesh with the driving gear 8, so that the driving gear 8 acts on the rack 12, so that the rack 12 pushes the power distribution drawer 3 to move, thereby realizing the pulling and drawing action of the drawer;

[0027] In order to provide power to the rotating rod 7, a rotating shaft 9 is provided on one side of the track 2, and a driving motor 10 is connected to the end of the rotating shaft 9. A gear set 11 is provided at the end of the rotating shaft 9 to be linked with the rotating rod 7. By controlling the driving motor 10 to rotate, the driving motor 10 drives the rotating shaft 9 to rotate, so that the rotating shaft 9 drives the gear set 11 to mesh and drive the rotating rod 7 to rotate, so that the rotating rod 7 drives the driving gear 8 to rotate, so that the driving gear 8 meshes with the rack 12;

[0028] Different from the power distribution drawers and rails on the upper layer, the rails and power distribution drawers on the lower layer are only equipped with sliding seats. However, space for installing the gear set, drive gear and drive motor must be reserved on the rails, and holes must be reserved on the bottom of the drawer for installing the rack, which can enhance the versatility of the equipment.

[0029] As a preferred solution, further, a through groove of a cylindrical structure is opened at the end of the track 2, and the rotating shaft 9 passes through the through groove. A limiting bearing sleeve is embedded in the through groove and arranged outside the rotating shaft 9. The limiting bearing is used to limit the rotating shaft 9 and reduce the rotation resistance.

[0030] As a preferred solution, further, a motor fixing bracket is provided outside the driving motor 10 and is installed on the power distribution cabinet body 1. The motor fixing bracket is connected to the power distribution cabinet body 1 by screws, and the motor fixing bracket plays a role of limiting the installation of the driving motor 10.

[0031] As a preferred solution, further, the sliding seat 4 is a rectangular structured plate, and at least one pair of rollers 13 are provided on the sliding seat 4 to contact the sliding groove 5, and the width of the sliding groove 5 matches that of the sliding seat 4. The sliding seat 4 is limited by the sliding groove 5, and the rollers 13 on the sliding seat 4 play a drag reduction role.

[0032] As a preferred solution, further, the rack 12 is arranged at the bottom of the side wall of the power distribution drawer 3, and at least a portion of the driving gear 8 passes through the side wall of the track 2 and engages with the rack 12.

[0033] As a preferred solution, further, the control switch 14 of the drive motor 10 is arranged on the outer wall of the distribution drawer 3. Different from other distribution drawers 3 on the distribution cabinet, the control switch 14 is set on the upper drawer. The rotation and direction of the drive motor 10 are controlled by the control switch 14, thereby achieving the purpose of pulling and pulling the drawer of the distribution cabinet.

[0034] From the above, it can be generally known that the drawer structure of the distribution cabinet adopts the form of setting tracks 2 on both sides of the drawer to limit and guide the distribution drawer 3. The rack 12 on the drawer cooperates with the gear structure installed on the track 2 to realize the automatic withdrawal and push-back of the drawer. The upper drawer can be pulled and pulled without human operation, avoiding the problem of inconvenient pulling and applying force. The track 2 structure of the upper drawer is similar to that of the lower drawer, except that the gear structure can be disassembled and assembled separately, and can be disassembled and assembled according to the situation, thereby improving the versatility of the equipment.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
