One end of the spring is fixedly connected to the moving plate, and the other end is fixedly connected to the inner wall of the guide groove. During the process of inserting the mounting plate into the cabinet body, the guide block will push the moving plate to move inward, simultaneously compressing the spring and the telescopic rod, and making the spring and the telescopic rod in a compressed state. After the mounting plate is completely inserted into the cabinet body, pull the pull block downward so that the sliding rod passes through the through hole on the mounting plate and then inserts into the slot, which can play a better fixing role for the mounting plate, and the ring main unit can be used normally. When pulling the pull blocks on both sides above the corresponding mounting plate upward to make the sliding rod disengage from the mounting plate, the moving plate will push the mounting plate out a certain distance under the action of the spring and the telescopic rod, which can make the disassembly of the mounting plate more convenient, thereby further improving the maintenance efficiency of the electrical equipment inside the ring main unit by the staff.

[0013] Preferably, a magnet block is fixedly connected to the upper end of the sliding rod, and an iron sheet attracted to the magnet block is fixedly connected to the top of the inner wall of the sliding cavity. Pull the pull block upward to make the sliding rod move upward. When the sliding rod moves to the top of the sliding cavity, the magnet block on the sliding rod is attracted to the iron sheet on the top of the inner wall of the sliding cavity, which can play a better fixing role for the sliding rod. The advantage of this setting is that it is not necessary to always manually pull the pull block upward when disassembling and assembling the mounting plate, which makes the disassembly and assembly of the mounting plate more convenient.

[0014] Preferably, a plurality of balls are fixedly connected to the bottom of the guide block, and the balls are linearly arrayed and equally spaced on the guide block. When disassembling and assembling the mounting plate, the guide block will slide inside the guide groove. Through the plurality of balls arranged at the bottom of the guide block, the friction between the guide block and the inner wall of the guide groove can be effectively reduced, making it more labor-saving for people to disassemble the mounting plate.

[0015] Preferably, arc-shaped grooves are formed on both sides of the pull block, and rubber pads are fixedly connected to the inner walls of the arc-shaped grooves. Through the arc-shaped grooves on both sides of the pull block, people can be better stressed when pulling the pull block. Through the rubber pads arranged on the inner walls of the arc-shaped grooves, the friction between the staff's hand and the pull block can be increased, effectively preventing the hand from slipping when people pull the pull block.

[0016] Preferably, the corners at the top of the through hole are chamfered. By chamfering the corners at the top of the through hole, it is more convenient for the sliding rod to insert into the through hole.

[0017] Preferably, a pull groove is formed on one side of the mounting plate, and the corners of the pull groove are rounded. Through the pull groove formed on one side of the mounting plate, after the staff inserts their hand into the pull groove, they can more easily pull the mounting plate out of the cabinet body. By rounding the corners of the pull groove, people's hands will be more comfortable when inserting their hands into the pull groove, and the skin of the hand will not be scratched by the corners of the pull groove.
