[0052] Two torsion springs, the torsion springs are fixed between the wrench and the side wall, so that the wrench can return when the external force is removed;

[0053] Two rotating arms 21, the rotating arms are fixed on the wrench; one end of the rotating arm is bent and fixed on the wrench, and the extension of the wrench is bent and fixed on the rotating arm;

[0054] Two link arms 31, one end of the link arm is rotatably arranged on the rotating arm, such as connected by bolts and nuts;

[0055] Two moving parts, the moving parts are located in the through holes or slots 51 inclined from top to bottom and in...

Embodiment 2

[0071] The switchgear with self-sealing function of the embodiment of the present invention, such as figure 2 Shown, different from embodiment 1 is:

[0072] 1. The linkage arm is no longer set, and the following structure is adopted:

[0073] two pulleys 71, said pulleys being fixed on the opposite side walls 1;

[0074] Two connecting ropes 61, one end of the connecting rope is fixed on the rotating arm, and the other end goes around the pulley and is fixed on the moving part;

[0075] 2. The upper side of the first shutter 81 is rotatably arranged on the opposite side wall;

[0076] Both ends of the lower side of the second shielding member 82 are fixedly connected to the moving member, and the upper side is rotationally connected to the lower side of the first shielding member 81;

[0077] The through holes or grooves 91 are inclined outward from top to bottom.

[0078] In the working method of the above switch cabinet, when the handcart pushes the wrench to move inwa...

Abstract

The invention provides a switch cabinet with a self-enclosing function, and a work method thereof. The switch cabinet comprises opposite side walls; wrenches are rotationally arranged on rotating shafts, and the rotating shafts are fixed on the relative side walls; torsion springs are fixed between the wrenches and the side walls; rotation arms are fixed on the wrenches; moving pieces are disposed in inclined limiting through holes or grooves in the opposite side walls and are connected with the rotation arms; one sides of first shielding pieces are rotationally arranged on the relative side walls; the two ends of one side of each second shielding piece are fixedly connected with the moving pieces, and the other sides of the second shielding pieces are rotationally connected with the other sides of the first shielding pieces. The switch cabinet with the self-enclosing function has the advantages of good protection effect and the like.

Description

technical field [0001] The invention relates to a switch cabinet, in particular to a switch cabinet with a self-sealing function and a working method thereof. Background technique [0002] At present, the basic structure of the switch cabinet is: cabinet body, handcart, and the grounding of the handcart is through the fixed cabinet body. When the handcart enters and pulls out of the cabinet body, the grounding device of the cart cooperates with the grounding device of the handcart. , separation. When the handcart exits, the high-voltage equipment in the switch cabinet is exposed, and the operator is easy to accidentally touch it, which will cause personal injury. Contents of the invention [0003] In order to solve the above-mentioned shortcomings in the prior art solutions, the present invention provides a switchgear with good protection effect and self-sealing function. [0004] The purpose of the present invention is achieved through the following technical solutions:...
