Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage power distribution cabinets, in particular to a pull-out low-voltage power distribution cabinet. Background Art

[0002] Low-voltage distribution cabinets are generally used by power users such as power plants, substations, factories and mines. They use a distribution system with an AC frequency of 50Hz, a rated working voltage of 380V, and a rated working current of up to 3150A. They are used for power conversion, distribution and control of power, lighting and distribution equipment.

[0003] In the prior art, in a patent application with the authorization publication number CN218449045U and the authorization publication date 2023-02-03, entitled "A Pull-out Low-voltage Distribution Cabinet", when maintaining the electrical equipment on one of the mounting plates, the electrical equipment can be maintained by pulling out one of the mounting plates according to the above operation alone, and the electrical equipment on the other mounting plates does not need to be moved, and the working status of other electrical equipment in the cabinet is not affected;

[0004] During the actual use of the above-mentioned device, in order to solve the problem that the entire bracket needs to be pulled out and opened each time the bracket is pulled out, a separate pulling operation is implemented. However, this method requires multiple pulling operations, which increases the difficulty, time and risk of maintenance and inspection, and is inconvenient to adjust the storage space according to the size of the equipment.

[0005] Therefore, we propose a pull-out low-voltage distribution cabinet to solve the above-mentioned problems. Utility Model Content

[0006] 1. Technical problems to be solved by the utility model:

[0007] The purpose of the utility model is to provide a pull-out low-voltage power distribution cabinet to solve the problems in the current market raised by the above background technology.

[0008] 2. Technical solution:

[0009] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pull-out low-voltage power distribution cabinet, comprising a low-voltage power distribution cabinet body placed flat on the ground, a storage rack body is fitted inside the low-voltage power distribution cabinet body, and casters are installed on both sides of the front of the lower end of the storage rack body, and the storage rack body slides out of the interior of the low-voltage power distribution cabinet body through the casters;

[0010] Threaded rods and guide rods are fixed on both sides of the storage rack, and support seats are jointly sleeved on the outer sides of the threaded rods and the guide rods. A mounting frame is connected between the left and right support seats through a pull-out assembly, and the mounting frame slides out of the storage rack through the pull-out assembly.

[0011] Furthermore, the storage rack and the low-voltage power distribution cabinet form a front-to-back sliding structure, and the casters installed at the bottom of the storage rack are in contact with the ground.

[0012] Through the above technical solution, the storage rack can be directly pulled out from the inside of the low-voltage distribution cabinet, and the stability is improved by the casters.

[0013] Furthermore, a rotating cylinder is installed on the middle bearing of the support seat, and the rotating cylinder is threadedly sleeved on the outside of the threaded rod, and the inner wall of the support seat is in contact with the outer wall of the guide rod.

[0014] Through the above technical solution, after the rotating drum is rotated, the position of the support seat on the outer side of the threaded rod can be adjusted.

[0015] Furthermore, the pulling assembly includes rollers rotatably installed on both sides of the mounting frame and a movable plate fixedly installed on the rear side of the mounting frame, a fixed plate is correspondingly provided on the front side of the movable plate, and the fixed plate is fixedly installed on the side of the support seat, and the fixed plate and the movable plate are located on the same horizontal plane.

[0016] Through the above technical solution, the friction force during pulling can be reduced by the roller, and the pulling distance can be limited by the cooperation between the movable plate and the fixed plate.

[0017] Furthermore, the rollers are symmetrically distributed up and down about the center of the support seat, and the rollers are attached to the surface of the support seat, and the rollers are distributed at equal intervals.

[0018] Through the above technical solution, the roller can improve the stability of the pulled-out installation frame.

[0019] 3. Beneficial effects:

[0020] By adopting the technical solution provided by the utility model, compared with the prior art, the pull-out low-voltage power distribution cabinet of the utility model can be pulled out as a whole through the storage frame, and a mounting frame can be pulled out separately at the same time, which improves the flexibility for subsequent maintenance and overhaul work. The specific contents are as follows:

[0021] By sliding the storage rack forward and backward inside the low-voltage distribution cabinet, when the overall pulling and pulling operation is required, the storage rack can be pulled out from the inside of the low-voltage distribution cabinet. During the pulling and pulling process, the front end of the storage rack can improve the load-bearing capacity and enhance the anti-deformation performance under the support of the casters. When a single device needs to be repaired and overhauled, the installation rack can be pulled out from the storage rack. Under the action of rollers arranged at equal intervals, the friction can be reduced, the contact area can be expanded, the stability can be improved, and the pulling and pulling distance of the installation rack can be limited by the cooperation of the movable plate and the fixed plate.

[0022] By rotating the drum, during the rotation of the drum, the threaded connection between the drum and the threaded rod and the fit between the support seat and the guide rod are utilized to drive the support seat to slide up and down on the threaded rod, thereby driving the mounting frame to adjust the height up and down on the storage rack until it reaches a suitable position, so as to flexibly adjust the distance between the two mounting frames according to the size of the equipment.
