Description

Technical Field

[0001] This utility model relates to the field of control cabinet technology, specifically a control cabinet that is easy to operate and maintain. Background Technology

[0002] A control cabinet is a device that assembles switching equipment, measuring instruments, protective electrical appliances, and auxiliary equipment in a closed or semi-closed metal cabinet or panel according to electrical wiring requirements. Its layout should meet the requirements for normal operation of the power system. Control cabinets are all hollow rectangular boxes, with various components installed directly inside. Due to the depth of the installation location, the installation space is relatively cramped, resulting in a limited field of vision for maintenance, which is very unfavorable for the installation of related components and subsequent maintenance.

[0003] Chinese Patent CN217508054U discloses a high- and low-voltage control cabinet that is easy to operate and maintain, relating to the field of high- and low-voltage control cabinet technology. The cabinet includes a control cabinet body structure, which comprises a cabinet body. An installation structure is provided inside the cabinet body, including an equipment mounting bracket. A mounting side frame is fixedly connected to one side of the mounting bracket, and connecting shafts are fixedly connected to both the upper and lower ends of the mounting side frame. A connecting side frame is provided on one side inside the control cabinet body, and sliding slots are provided at both the upper and lower ends of the connecting side frame. This invention, through the installation side frame and connecting side frame, allows for easy maintenance during operation. After opening the door, the equipment mounting bracket can be pulled out, allowing it to move out of the control cabinet body for easy maintenance of the equipment on the mounting bracket. This method is not only convenient for maintenance but also relatively simple, making this invention highly practical.

[0004] However, the above technical solution has the following drawbacks: the high and low voltage control cabinets that are easy to operate and maintain require manual disassembly of the mounting bracket for maintenance and repair. The disassembly and installation of the mounting bracket 21 are inconvenient and may easily damage the equipment on the mounting bracket. Utility Model Content

[0011] The fixed frame is connected to the inner wall of the cabinet, the double threaded rod is rotatably connected to the fixed frame, the drive assembly is connected to the fixed frame, and the drive assembly is connected to the double threaded rod for transmission.

[0012] The mounting block has two slidingly connected fixing frames. The two mounting blocks are threadedly connected to the double threaded rod and symmetrically distributed on it.

[0013] The push plate is equipped with multiple telescopic rods, the other end of which is connected to the surface of the fixed frame. The fixed block is connected to the surface of the push plate. There are two support rods, which are rotatably connected to two mounting blocks respectively. The other end of each support rod is rotatably connected to a fixed block.

[0014] Preferably, it also includes a spring;

[0015] Multiple springs are provided, each corresponding to a fixed rod. The spring is sleeved on the outside of the corresponding fixed rod. The end of the fixed rod near the door panel has an end cap. The surface of the mounting bracket near the door panel and the surface of the end cap press the two ends of the spring together, so that the spring is in a compressed state.

[0016] Preferably, bolts are also included;

[0019] Preferably, the outer surface of the door panel is provided with a handle.

[0020] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0021] 1. In this utility model, when maintenance is required, the corresponding push-out mechanism of the door panel is opened to push the corresponding mounting bracket out of the cabinet. The mounting bracket is close to the opening of the cabinet for easy maintenance.

[0022] 2. In this utility model, when the cooling fan is started, the low-temperature air from the outside enters the cabinet, and the heat inside the cabinet is discharged through the air outlet, preventing the internal temperature of the cabinet from being too high and affecting the performance of the internal equipment.

[0023] 3. In this utility model, during maintenance, the push-out mechanism pushes the mounting bracket closer to the cabinet opening for easy maintenance. After maintenance is completed, the push-out mechanism retracts, and the spring drives the mounting bracket to reset, making it convenient to use. Attached Figure Description
