Description
Technical field
The utility model relates to a kind of lockset, and more particularly, it relates to a kind of high and low voltage switch cabinet link lock.
Background technology
The cabinet door lock of domestic the most frequently used switchboard such as KYN28A high voltage switchgear equipment is as shown in Figure 2; Be provided with lock core 41, lock tube 44, jump ring 42,43, the key rotation lock core through special use screws in the bolt on the cabinet, and its shortcoming is that jump ring 42,43 in use ruptures easily and comes off because of stressed; Minimum on each cabinet 3 door locks to be installed; Need open each door lock respectively during locking cabinet door, consuming time longer, can be like emergency episode because of the time of the overlong time delay processing accident of opening the cabinet door.If the planeness of ground, job site matrix manufacturing is bad, cause the out-of-flatness of switchgear assembly unit, the situation of the riveting nut on the door lock misalignment cabinet can appear.
Summary of the invention
To the deficiency that prior art exists, the purpose of the utility model be to provide a kind of can with door of switch cabinet good fit, not fragile, high and low voltage switch cabinet link lock that the cabinet door opening time is short.
For realizing above-mentioned purpose; The utility model provides following technical scheme: a kind of high and low voltage switch cabinet link lock, include support, pivot pin, guide peg, door lock, hook, and described stent length and cabinet door are suitable; Its cross section becomes " U "; Both sides are provided with several strip holes, be equipped with on the guide peg with support on the identical and pivot pin that can in the strip hole, move up and down of strip hole quantity, the strip hole of pivot pin and support both sides is suitable and pass the strip hole of support both sides; Door lock is provided with the pull bar that is connected with guide peg, and pivot pin drives the guide peg completion through pull bar and moves up and down; Hook is suitable with pivot pin.
Through adopting technique scheme; Make cabinet door multiple spot fix, firmly do not receive the effects of ground and cabinet splicing, when switchgear is short-circuited accident; Powerful arc light and air-flow can not be washed the cabinet door open; Be difficult for being damaged, and can with the door of switch cabinet good fit, simultaneously the cabinet door opening time is short.
The utility model further is set to: described guide peg is the thin plate banded structure, and its length and support are suitable.
Through adopting technique scheme, further make rational in infrastructure, the no-float between parts.
