Description
Technical field
The utility model is a kind of door lock assembly, particularly a kind ofly strengthens grounded continuous door lock assembly for power system.
Background technology
In power system, because electrical continuity problem may be charged for a long time, there is certain potential safety hazard when operating in the metal shell of electric fixtures.
Summary of the invention
The utility model mainly solves the deficiencies in the prior art, provides a kind of operation reliable, increase security performance strengthen grounded continuous door lock assembly for power system.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind ofly strengthen grounded continuous door lock assembly for power system, comprise plate of locking a door, positioning sleeve and grounding nut, the outer wall of described grounding nut is provided with at least one ground connection projection, the upper end of described positioning sleeve is provided with gear and connects end, described ground connection projection connects end with gear and crimps mutually, the middle-end of described positioning sleeve is provided with the sleeve with the clamping of grounding nut phase, the lower end of described positioning sleeve is provided with arc of rotation plate, rotation stud is provided with in described positioning sleeve, rotation hole is provided with in described plate of locking a door, described rotation stud extends downwards in rotation hole, described rotation stud is located with plate of locking a door mutually by end pin, described arc of rotation plate is matched with the outer wall of plate of locking a door, back-moving spring is provided with between described positioning sleeve and rotation stud.
As preferably, described gear connects end, sleeve, arc of rotation plate in integration distribution, and the outer wall of described grounding nut is provided with 4 equally distributed ground connection projections, and described ground connection projection is triangular shape.
As preferably, in described plate of locking a door, be provided with door-plate locating convex block.
Lock for door of switch cabinet, expose operating grip etc. and must keep ground connection electrical continuity.Ground connection projection is when fastening, and ground connection projection can puncture skin of paint, and embeds in cabinet door, and door lock and cabinet door keep good ground connection electrical continuity, the personal safety of protection operating personnel.Meanwhile, the design of ground connection projection also increases frictional force, reaches good anti-loosing effect.
Therefore, the utility model is provided for power system and strengthens grounded continuous door lock assembly, and operating characteristics is outstanding, improves safety.
