The utility model content
The technical problem that the utility model will solve provides the interlock of a kind of switch cubicle door and earthed switch, and is simple in structure, low cost of manufacture, and the reliability of action is higher.
For achieving the above object; The technical scheme of the utility model is: the interlock of a kind of switch cubicle door and earthed switch, comprise hook plate, snap close, cam, connecting rod, guiding trestle, and snap close is fixed on the switch cubicle door; The middle part of hook plate is articulated on the fulcrum of switch cubicle side plate; The front end of hook plate can fasten or be separated with snap close, and cam is fixed on the operating axis of earthed switch, guiding trestle be fixed on the side plate of switch cubicle and be in cam below; Connecting rod passes that its top of guiding trestle contacts with cam, the rear end of lower end and hook plate is articulated, and is provided with spring between connecting rod and the guiding trestle and makes connecting rod near cam.
Preferably a kind of mounting means of spring does, wears a latch in the middle and upper part of connecting rod, and spring housing withstands on the guiding trestle at an end on the connecting rod, the other end withstands on the latch.
Preferred described guiding trestle is a L shaped plate, and an end is provided with installing hole, the other end is provided with the through hole that lets connecting rod pass.
Described snap close can be selected a kind of L shaped plate for use, and an end is provided with installing hole, and the other end is provided with the through hole that matches with hook plate.
Described snap close also can be selected the bolt that is fixed on the switch cubicle door for use, leaves the gap between bolt and the switch cubicle door.
The utility model is made up of hook plate, snap close, cam, connecting rod, guiding trestle and spring; Can realize that the relevant position of switch cubicle door and earthed switch carries out interlocking; Prevent artificial random unlatching switch cubicle door and touch the high-voltage charged body in the switch cubicle; Parts significantly reduce, and are simple in structure, and manufacturing cost is lower; On the other hand, through the rotation of cam, drivening rod moves up and down, and moving up and down of connecting rod also makes the hook plate front end move up and down, and front end and the snap close of hook plate are fastened or breaks away from, and moves simplyr, and reliability is higher.
