[0027] As Figures 1 - 3 shown, the embodiment of the present application provides a door opening and closing control structure, which includes a buckle body 100, a lock body 200, a first transmission rod 300, a second transmission rod 400, and a driving assembly 500. Among them, the buckle body 100 is installed on the electric control cabinet by bolts, and a buckle groove 110 is opened on the buckle body 100. The lock body 200 is installed on the door by bolts. An installation space 210 is opened in the lock body 200, and the first transmission rod 300, the second transmission rod 400, and the driving assembly 500 are all arranged in the installation space 210.

[0028] The first transmission rod 300 is rotatably installed in the lock body 200. Specifically, a rotating shaft 220 is fixed in the lock body 200, and the middle part of the first transmission rod 300 is rotatably installed in the lock body 200 through the rotating shaft 220. And a torsion spring is installed between the first transmission rod 300 and the lock body 200. One end of the first transmission rod 300 extends to the outside of the lock body 200, and a buckle plate 310 is fixed at this end. The buckle plate 310 is snap-connected with the buckle groove 110. Specifically, the buckle plate 310 is of a triangular structure, and the opening end of the buckle groove 110 has a baffle 120 adapted to the buckle plate 310. The buckle plate 310 can enter the buckle groove 110 and be buckled on the baffle 120, so as to realize the connection between the buckle body 100 and the lock body 200, and the door of the electric control cabinet can be closed. One end of the first transmission rod 300 away from the buckle plate 310 is fixed with a first transmission member 320, and the first transmission member 320 is used to cooperate with the second transmission rod 400.

[0029] The second transmission rod 400 is slidably installed in the lock body 200 along its own length direction. One end of the second transmission rod 400 is provided with a second transmission member 410, and the first transmission member 320 is located on the movement track of the second transmission member 410. When the second transmission member 410 contacts the first transmission member 320, it can force the first transmission rod 300 to rotate, so that the buckle plate 310 is separated from the buckle groove 110, so as to realize the separation between the buckle body 100 and the lock body 200, and the door of the electric control cabinet can be opened.

[0030] In order to make the cooperation between the first transmission member 320 and the second transmission member 410 smoother, both the first transmission member 320 and the second transmission member 410 in this embodiment are designed as hemispherical protrusions. By setting like this, when the second transmission member 410 contacts the first transmission member 320, it can drive the first transmission rod 300 to rotate relatively smoothly. In another embodiment, the first transmission member 320 and the second transmission member 410 can also be designed as triangular structures.

[0031] The driving assembly 500 is installed in the lock body 200 and is used to drive the second transmission rod 400 to move. When the staff needs to open the door of the electric control cabinet, only need to drive the second transmission rod 400 to move to the right through the driving assembly 500, so that the second transmission member 410 contacts the first transmission member 320, thereby driving the first transmission rod 300 to rotate, so that the buckle plate 310 is separated from the buckle groove 110, so as to realize the separation between the buckle body 100 and the lock body 200, and the door of the electric control cabinet can be opened; when the staff closes the door of the electric control cabinet, the buckle plate 310 of the first transmission rod 300 is connected with the buckle groove 110, and the connection between the buckle body 100 and the lock body 200 can be realized, and the operation is convenient.

[0032] In this embodiment, the driving assembly 500 includes an electromagnet 510, an armature 520, and a spring 530. Among them, the electromagnet 510 is fixed inside the lock body 200, the armature 520 is installed at one end of the second transmission rod 400 away from the second transmission member 410, and the spring 530 is installed between the electromagnet 510 and the armature 520. Specifically, a first installation groove 521 is provided on the armature 520, a second installation groove 511 is provided on the electromagnet 510, and both ends of the spring 530 are installed in the first installation groove 521 and the second installation groove 511 respectively. When the electromagnet 510 is energized, the armature 520 is subjected to the adsorption force of the electromagnet 510, driving the second transmission rod 400 to move towards the side close to the electromagnet 510; when the electromagnet 510 is de-energized, the armature 520 is subjected to the elastic force of the spring 530, driving the second transmission rod 400 to move towards the side away from the electromagnet 510.

[0033] In this embodiment, the door opening and closing control structure further includes a door handle 600, and the door handle 600 is fixed to the lock body 200 by bolts, facilitating the staff to open the door.

[0034] In this embodiment, the door opening and closing control structure further includes a switch member 700. The switch member 700 is electrically connected to the electromagnet 510 and is used to control the on and off of the electromagnet 510. The switch member 700 can be a push-button switch or a touch switch. It should be noted that when it is necessary to open the door of the electric control cabinet, the switch member 700 can be directly clicked to turn the electromagnet 510 on and off; after the electromagnet 510 is energized for 5 - 10 seconds, it can automatically cut off the power.

[0035] In addition, a power supply for powering the electromagnet 510 is detachably installed inside the lock body 200.

[0036] In another embodiment, the driving assembly 500 can also be an electric push rod. When it is necessary to open the door, the second transmission rod 400 is driven by the electric push rod to move to the right, so that the second transmission member 410 contacts the first transmission member 320, thereby driving the first transmission rod 300 to rotate, causing the buckle plate 310 to disengage from the buckle groove 110, thereby realizing the separation between the buckle body 100 and the lock body 200, and the door of the electric control cabinet can be opened. After opening the door, the electric push rod drives the second transmission rod 400 to move to the left again, so that the second transmission rod 400 is reset, facilitating subsequent door closing operations.
