Description

Technical Field

[0001] The utility model relates to a frame structure, in particular to a switch cabinet frame structure which is convenient for maintenance. Background Art

[0002] The main function of the switchgear is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and energy conversion in the power system. The components in the switchgear mainly include circuit breakers, disconnectors, load switches, operating mechanisms, transformers and various protective devices.

[0003] The traditional maintenance method is to open the panel, label the equipment in the shell, record and take photos to check the electrical and mechanical equipment in the cabinet to see if there are any problems such as damage, aging, loose grounding wires, etc. If the above problems occur, the maintenance personnel need to repair the problematic equipment or dismantle and replace it. However, the operating space in the shell is small and the visibility is low. It is not convenient for maintenance personnel to perform detailed maintenance on the problematic equipment, which is prone to misrepair. It is more troublesome to directly dismantle it for maintenance.

[0004] Therefore, it is necessary to design a switch cabinet frame structure that is easy to maintain. Utility Model Content

[0005] In order to overcome the shortcomings of inconvenient maintenance in the shell, easy to make wrong maintenance, and troublesome to directly dismantle for maintenance, the technical problem of the utility model is to provide a switch cabinet frame structure that is easy to maintain.

[0006] The technical solution is: a switch cabinet frame structure that is easy to maintain, including a tripod, a shell, a cabinet door, a first guide rod, a mounting plate, a handle, a winding rack and a wire outlet plate. The four corners of the bottom of the shell are fixedly connected to the tripod, the front of the shell is rotatably connected to the cabinet door, the four corners of the inner rear side of the shell are installed with a first guide rod, the mounting plate is slidably connected between the four first guide rods, a handle is fixedly connected to the upper side of the front of the mounting plate, a winding rack is installed on the front of the mounting plate, and two upper and lower wire outlet plates are symmetrically fixed to the left and right sides of the mounting plate.

[0007] Furthermore, the outlet plate slides on the housing.

[0008] Furthermore, it also includes a first spring, a buffer plate and a second spring. Multiple first springs are connected between the shell and the mounting plate, each first spring is surrounded by the first guide rod, a second spring is installed on the rear side of the shell, and a buffer plate is fixed to the other side of the second spring.

[0009] Furthermore, it also includes a second guide rod, an oblique block, a third spring and a push rod. Two upper and lower second guide rods are fixedly connected on the left and right sides of the shell. An oblique block is slidably connected between two adjacent second guide rods. Multiple third springs are fixedly connected on the left and right sides of the shell. Each third spring surrounds the second guide rod. Push rods are fixedly connected on the sides of the oblique blocks that are away from each other, and the push rods slide in the shell.

[0010] Furthermore, it also includes a third guide rod, a fourth spring, a push plate and a slider. The third guide rod is fixedly connected to the left and right sides of the outer side of the shell, and the other side of the third guide rod is slidably connected to the push plate. The fourth spring is wound between the third guide rod and the push plate, and the slider is fixedly connected to the left and right sides of the inner side of the push plate.

[0011] Furthermore, the slider slides on the shell.

[0012] The beneficial effects of the utility model are as follows: 1. The utility model uses the first guide rod and the handle to pull out the mounting plate and the electrical equipment for maintenance, so that the maintenance personnel are not restricted by the narrow space and can see more clearly whether the equipment has problems such as damage, aging, loose grounding wire, etc., which makes maintenance more convenient and reduces the possibility of erroneous maintenance.

[0013] 2. The utility model uses the first spring, the buffer plate and the second spring to enable the mounting plate to reset itself after being pulled out, and the buffer plate and the second spring can prevent the electrical equipment from violently colliding during the resetting process, causing the equipment to shift. The mounting plate is then positioned by the cooperation of the second guide rod, the oblique block, the third spring and the push rod, so that the maintenance personnel do not need to hold the mounting plate all the time to prevent sudden resetting during the maintenance process.

[0014] 3. The utility model uses the third guide rod, the fourth spring, the push plate and the slider, and can push the push plate to push out the oblique block, making it more convenient to reset the mounting plate. BRIEF DESCRIPTION OF THE DRAWINGS
