DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] See also Figures 1 to 4 The utility model provides a technical solution: a dustproof PLC control cabinet, comprising a cabinet body 1, openings 101 opened on both sides of the cabinet body 1, and a dustproof net 3 inserted in the opening 101, the front side wall of the dustproof net 3 is fixedly connected with two symmetrically distributed protrusions 4, and the two protrusions 4 are both provided with arc-shaped card slots 401 on the side close to each other, and the side wall of the cabinet body 1 is fixedly installed with two symmetrically distributed locking mechanisms 5;

[0024] The dustproof net 3 is used to dissipate heat and prevent dust from entering the cabinet 1. The heat generated by the components is discharged from the cabinet 1 through the dustproof net 3, thereby ensuring the normal operation of the components. The dustproof net 3 is installed on the side wall of the cabinet 1 through the cooperation of the locking mechanism 5 and the protrusion 4.

[0025] Specifically, the locking mechanism 5 includes a positioning plate 51 fixed to the side wall of the cabinet 1, and a plurality of elastic telescopic rods 52 fixedly installed on the side wall of the positioning plate 51. The other ends of the plurality of elastic telescopic rods 52 are commonly fixedly connected to a base block 53. A damping shaft 54 ​​is rotatably inserted at the other end of the base block 53. The damping shaft 54 ​​is fixedly connected to a turning bar 55 at both upper and lower ends. A locking pin 56 is fixedly connected between the other ends of the two turning bars 55.

A spring 522 is fixedly connected between the end of the insertion rod 523 and the inner wall of the fixed sleeve 521, and the other end of the insertion rod 523 is fixedly connected to the base block 53.

[0027] When the dust screen 3 needs to be removed, the latch 56 is first pulled to move the latch 56 out of the arc-shaped slot 401, and then the latch 56 is rotated to move the latch 56 away from the protrusion 4; thus, the dust screen 3 can be removed from the opening 101, and the purpose of removing the dust screen 3 can be achieved quickly.

[0028] When installing the dustproof net 3, first place the dustproof net 3 in the opening 101, then pull the pin 56 in the direction of the protrusion 4, and rotate the pin 56 so that the position of the pin 56 corresponds to the arc-shaped slot 401. Then, release the spring 522 and pull the rod 523 to move in the direction of the fixing sleeve 521, so that the rod 523 pulls the base block 53 to move toward the positioning plate 51, and finally the pin 56 is engaged in the arc-shaped slot 401, thereby achieving the purpose of limiting and tightening the dustproof net 3.

[0029] Furthermore, the latch pin 56 is a cylindrical pin, and the latch pin 56 matches the arc-shaped latch slot 401 structure.
