[0062] The use method and advantages of the present invention: The use method of the double-sided movable opening and closing low-voltage electrical cabinet which is convenient for maintenance, the working process is as follows:

[0063] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 , Fig.14 As shown: when the electrical components 9 inside the electrical cabinet frame 1 are inspected, the front cover door 3 is opened, and the insertion rod 62 is pulled by the restoring force of the compression spring 63 to slide forward in the circular groove 61, thereby driving the deflection plate 81 to pull the outer sleeve of the spring telescopic plate 82 out of the fixed sleeve 83, thereby releasing the restriction of the spring telescopic plate 82 on the rear cover door 2, making it convenient for the user to open the rear cover door 2;

[0064] When the insertion rod 62 slides forward in the circular groove 61, the auxiliary push plate 65 is pulled to deflect by the push plate 64, and the extrusion deflection plate 67 is pulled to deflect under the action of the power connecting rod 66, thereby pushing the L-shaped extrusion plate 69 to slide in the transverse groove 68 and then reset;

[0065] Then the user pulls the handle at the front end of the pulling frame 51 and depresses the handle 517, so that the T-shaped extrusion plate 516 on the handle 517 slides in the T-shaped through slot 515 and separates from the top of the pressing cylindrical block 513. At this time, the pressing cylindrical block 513 moves upward under the action of the restoring force of the second spring telescopic rod 514 and separates from the bottom of the inner wall of the guide slot 519. Then the user pulls the pulling frame 51 forward, and the notched outer sleeve 512 slides in the guide slot 519 during the forward movement of the pulling frame 51.

[0066] When the notched outer sleeve 512 slides to the front end of the guide groove 519, the second placement rack 52 near the edge of the inverted T-shaped mounting plate 4 slides toward the middle part of the inverted T-shaped mounting plate 4 through the notched outer sleeve 512 at its lower end, and then drives the six placement racks 52 to expand in a straight line at equal distances under the action of the diamond-shaped connecting frame 59, and the two push rods 57 abutting against each other after the distance between the six placement racks 52 becomes larger are separated from each other. At this time, the push rod 57 pulls the rectangular extrusion plate 56 to slide in the U-shaped through groove 55 under the action of the return spring 58, so that the limiting plug plate 54 is pulled out of the limiting groove of the electrical component 9, which is convenient for the user to remove the electrical component 9 from the placement rack 52 for maintenance. At this time, the T-shaped extrusion plate 516 moves backward and resets to squeeze the top of the pressing cylindrical block 513, so that the lower end of the pressing cylindrical block 513 abuts against the guide groove 519, positioning the pulled-out pulling frame 51;

[0067] When the user has finished inspecting the electrical component 9, the user pulls the handle 517 again to separate the T-shaped extrusion plate 516 from the upper end of the pressing cylindrical block 513, and then the user pushes the pulling frame 51 to move back to reset. During the backward movement of the pulling frame 51, the notched outer sleeve 512 slides in the guide groove 519 and drives the diamond-shaped connecting frame 59 to shrink, driving the six placement frames 52 to approach each other, thereby making the rectangular extrusion plate 56 at one end of the push rod 57 move toward the inside of the U-shaped through groove 55, and then pushing the limiting plug plate 54 to be inserted into the limiting groove on the electrical component 9, so as to limit and fix the installed electrical component 9;

[0068] When the pulling frame 51 moves backward to the rear side of the top surface of the inverted T-shaped mounting plate 4, the user closes the front cover door 3, and the extrusion rod 62 moves backward, and drives the pushing plate 64 to squeeze the auxiliary pushing plate 65, so that the power connecting rod 66 pushes the extrusion deflection plate 67 to deflect, so that the end with the inclined surface of the L-shaped extrusion plate 69 squeezes the cross-section of the lower end of the pressing cylindrical block 513, so that the pressing cylindrical block 513 moves upward and separates from the bottom surface of the inner wall of the guide groove 519, and then the pushing plate 64 squeezes the pulling frame 51 backward, ensuring that the pulling frame 51 can stably slide to the rear end of the guide groove 519, ensuring that the electrical components 9 on the pulling frame 51 are stably reset, and avoiding the occurrence of incomplete reset of the electrical components 9;

[0069] After the front cover door 3 is closed, the deflection plate 81 is driven to deflect by the insertion rod 62, so that the deflection plate 81 pushes the outer sleeve of the spring expansion plate 82 to be inserted into the fixing sleeve 83, and the rear cover door 2 is locked, completing the user's maintenance of the electrical components 9 inside the electrical cabinet frame 1.
