Abstract
The utility model relates to a movable door mechanism of a switch cabinet. The movable door mechanism comprises an upper movable door, a lower movable door, a synchronization mechanism and propelling mechanisms, wherein the propelling mechanisms are in linkage connection with the lower movable door, the upper movable door is linked with the lower movable door through the synchronization mechanism, each propelling mechanism comprises a side plate, a connecting rod, a push rod, a lockhole and a lock catch, one ends of the connecting rods, the lockholes and the lock catches are respectively hinged on the side plates, the connecting rods are connected with the lower movable door, the push rods are in linkage connection with the connecting rods, the push rods are connected with reset springs, the lockholes are in linkage connection with the push rods, openings of the lockholes are arranged outwards, a locking groove is formed at the lower end of each lock catch, the lock catches are arranged on the upper ends of the lockholes in a buckling mode, and the front end of each lock catch is an inclined surface inclining upwardly. The movable doors are locked when a handcart leaves through the cooperation of the lock catches and the lockholes in the propelling mechanism, the purpose of automatic locking is achieved, the lockholes are locked by the lock catches under the action of gravity, the integral structure is simple, and the locking effect is good.
Description
Technical field
The utility model relates to a kind of shutter mechanism of switch cabinet.
Background technology
Promote connecting rod when existing shutter mechanism of switch cabinet normally advances by handcart and open valve, handcart leaves valve and closes, but because the connecting rod of valve can't lock, leave and make also may promote link motion due to other objects in the external world at handcart, cause valve extremely to be opened, affect the electric property in valve.
Summary of the invention
The purpose of this utility model is to overcome the defect of prior art, and a kind of shutter mechanism of switch cabinet with auto-lock function is provided.
For achieving the above object, the utility model adopts a kind of shutter mechanism of switch cabinet, comprise valve, lower valve, lazy-tongs, propulsive mechanism, propulsive mechanism and lower valve are connected, upper valve is by lazy-tongs and the interlock of lower valve, described propulsive mechanism comprises side plate, connecting rod, push rod, lockhole, snap close, connecting rod, one end of lockhole and snap close all is hinged on side plate, connecting rod is connected with lower valve, push rod is connected with connection-rod linkage, be connected with back-moving spring on push rod, lockhole and push rod are connected, the outward opening setting of lockhole, the snap close lower end forms lock slots, snap close rides over the lockhole upper end, the snap close front end is acclivitous inclined-plane.
The utility model further is set to described lazy-tongs and comprises two sprocket wheels and be connected in the chain between sprocket wheel, and two sprocket wheels are separately positioned on the same side of the lower end of the upper end of valve and lower valve, and chain oppositely links sprocket wheel.
The beneficial effects of the utility model are by locking valve when being engaged in handcart and leaving of propulsive mechanism inner lock buckle and lockhole, and reach the purpose of automatic blocking, and snap close locks lockhole by gravity, and overall structure is simple, and locking effect is good.Lazy-tongs adopt the synchronous upper and lower valve of sprocket wheel, simple in structure.
