In the utility model, by arranging the locking assembly inside, when the box cover and the box body are closed, the box cover is directly installed on the box body vertically, and the locking rod will enter the locking hole vertically. When the positions of the magnetic blocks are aligned, since the magnetic poles of the locking magnetic column are different from the magnetic poles of the inner magnetic block, the inner magnetic block will generate a certain gravitational force on the locking magnetic column, so that the locking magnetic column is displaced into the slot hole of the locking rod, which can be Complete the locking of the closed box cover and the box body without additional operations. After the combination, the two have a high degree of tightness and good stability. At the same time, after the box cover and the box body are closed, the outer contact and the inner contact are in contact with each other. , so that the circuit can be connected to start the contactor, and when the two are separated, the contactor can be disconnected, so as to realize the safe start and stop of the control loop, and the use effect is good.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

1-4, the present utility model provides a technical solution: a safety start-stop control circuit with position locking, comprising a box cover 2 and a box body 3, a box cover 2 is installed above the box body 3, and the box cover The bottom of 2 is fixedly installed with locking rod 5 and outer contact 7, the top of box body 3 is fixedly installed with limiting column 4, and the top surface of box 3 is respectively located directly below outer contact 7 and locking rod 5 with inner holes provided. 9 and the lock hole 10, the inner contact 8 is fixedly installed inside the inner hole 9.
