Description
Technical field
The utility model relates to a kind of electric cabinet lock, especially a kind of column type electricity cabinet lock.
Background technology
In recent years the performance of each element in insulation, structure and the cabinet of high-tension electricity cabinet has been carried out continuous improvement, but can not avoid the arc short circuit accident fully, report has been arranged during personal injury incident that electric arc causes.
The common electric cabinet lock of high-tension electricity cabinet stretches in the horizontal direction through key or button drive locking bolt (dead bolt) usually and accomplishes cutting out and opening action electric cabinet door at present; Electric cabinet lock like this and the bonding strength of cabinet and little; When the inner generation of cabinet arc short circuit accident, the impact force that electric arc produces can be washed the cabinet door easily open, causes cabinet to damage; If the people is arranged just at operating equipment when having an accident, also can cause serious injury to the person.
Summary of the invention
The problem that the utility model will solve provides a kind of electric cabinet lock with sufficient intensity of guaranteeing to connect between cabinet door and the cabinet, and it can effectively prevent the impact force that failover electric arc produces, and washes the cabinet door open and injures the staff, especially is suitable for high-tension switch cabinet.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of electric cabinet lock; Comprise housing, be arranged on the lock core in this housing; Said housing is the cylinder of band shirt rim, top, and the upper end of inner walls is provided with the retainer plate of band through hole, is installed with the lock core that can move around on the retainer plate.Said lock core upper end is the spill circular groove, and the lock core lower end is a threaded rod; The external diameter of spill circular groove is greater than the external diameter of threaded rod; The center of spill circular groove is provided with cylindrical bump, and the outer rim symmetric position of spill circular groove is provided with bayonet socket respectively; The interior diameter of retainer plate is between the external diameter of the external diameter of spill circular groove and threaded rod, and threaded rod passes retainer plate and stretches out through housing bottom.
After electricity cabinet lock was placed on cabinet every plate, through key, the threaded rod precession that drives the lock core lower end was welded on the coupling nut on the doorframe.Because lock core is to adopt screw thread and the engaged mode that compresses of nut that electric cabinet door is closed, and has guaranteed that bonding strength, the connection reliability between cabinet door and the cabinet is strong.In addition; The lock core upper end is the spill circular groove of band cylindrical bump and bayonet socket; General tool is difficult to open electric cabinet lock, must use special matched key to form with electric cabinet lock with bayonet socket through cylindrical bump and be connected, and just can open, close electric cabinet lock; Avoid the unexpected unlatching of cabinet door, guaranteed the safety of electric cabinet.
Can be provided with on the said threaded rod and prevent that the hole that lock core comes off from using back-up ring, lock core can be movable back and forth between the hole is with back-up ring and retainer plate, and do not worry coming off because of lock core takes place misoperation.
Said housing outer wall can have annular groove, is with shaft block ring on the annular groove.When housing passes cabinet every plate,, can play the effect of location, slip-off preventing to electric cabinet lock through cooperating of shaft block ring and annular groove.
A kind of improvement as the utility model; Said electric cabinet lock can also comprise an external screw thread connector; The bottom of housing has the internal thread that is complementary with the external screw thread connector; When external screw thread connector and internal thread supporting fastening after, can prevent further that electric cabinet lock from coming off, and reinforce the bonding strength between cabinet door and the doorframe.
Said hole is during with the furthest of back-up ring and retainer plate, and when being fastenedly connected fully between promptly electric cabinet lock and doorframe, the end face of the spill circular groove of lock core can be lower than the end face of housing; When the hole was nearest with back-up ring and retainer plate, when the connection between promptly electric cabinet lock and the doorframe had been removed, the bottom of spill circular groove can exceed the end face of housing.After adopting such design; The operator can close or open electric cabinet door fully through judging the position of spill circular groove, and electric cabinet door is when tight; The design that the end face of spill circular groove is lower than the end face of housing is difficult for letting the lawless person prize, pry open lockset, has guaranteed the safety of electric cabinet.
The electric cabinet lock of the utility model can be selected galvanized steel material or chromium-plated steel material for use, and that the lockset that causes has is corrosion-resistant, long service life, advantage such as specious.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme; Has enough intensity between cabinet door and the cabinet; Avoid the unexpected unlatching of cabinet door; And when electric arc is broken down in cabinet inside, can prevent effectively that the impact force of inner generation from washing door open, have advantages such as simple in structure, that processing cost is low, connection is reliable, explosion-proof ability is strong.
