Description

The electric switch cabinet door lock

Technical field

The utility model relates to a kind of electric switch cabinet device, refers to a kind of electric switch cabinet door lock especially.

Background technology

Existing domestic the most frequently used switchboard such as KYN28A high-tension switch cabinet armored withdraw type ac metal closing switch gear (hereinafter to be referred as switchgear) cabinet every lock have lock core 41 as shown in Figure 2, lock tube 44,

jump ring

42,43 form, in the bolt on the key rotation lock core screw-in cabinet of special use, its shortcoming is a

jump ring

42,43 in use rupture easily and come off because of stressed, minimum on each cabinet door 3 door locks to be installed, locking cabinet Men Shixu opens each door lock respectively, consuming time longer, can incur loss through delay time of processing accident in the time of if anything crops up because of the overlong time 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, and often run at the scene in reality.

Summary of the invention

At the shortcoming of prior art, the purpose of this utility model is to provide that a kind of energy finely cooperates with door of switch cabinet, not fragile, electric switch cabinet door lock that the cabinet door opening time is short.

The technical scheme that its technical problem that solves the utility model adopts is: include support, pivot pin, guide peg, door lock, hook, its medium-height trestle, pivot pin, guide peg, door lock are loaded on cabinet door one side; Hook is loaded on the doorframe, and stent length and cabinet door match, and its cross section becomes approximate ' U ' shape, and there are several strip holes both sides; Guide peg is the thin plate banded structure, its length and support match, be equipped with on this guide peg with support on the identical pivot pin of strip hole number, the strip hole of pivot pin and support both sides matches and passes the strip hole of support both sides, pivot pin can move up and down in the strip hole; Door lock is installed on the cabinet door, and pull bar is arranged on door lock, and pull bar is connected with guide peg, and pull bar drives guide peg moves up and down pivot pin; Hook matches with pivot pin, pivot pin can be hooked, and is used to lock pivot pin.

The beneficial effects of the utility model are: can be fine cooperate with door of switch cabinet, not fragile, the unlatching of cabinet door is convenient and simple, has reduced the time of opening and closing cabinet door, cabinet door multiple spot is fixed, and firmly and not is subjected to the deviation effects of ground and cabinet assembly unit.When switchgear was short-circuited accident, powerful arc light and air-flow can not be washed the cabinet door open, had played good protective action, had also guaranteed site operation personnel's personal safety simultaneously.

Description of drawings

The utility model will be further described below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model.
