Being equipped with its lock core can be with the rotating gear of lock core, and lock tongue is to be engaged with gear and can be in that identical or opposite direction is same
Walk the positive stop strip of operation.
Such cabinet door lock is easy to process, simple in structure, however, after much time using, the connection of gear and lock core
Place easily occurs loosening, it is necessary to which operating personnel implement to fix to it often, and operating process is relatively complicated, and after maintenance repeatedly,
Clamping stagnation occurs in linkage between gear and positive stop strip.
The content of the invention
In view of the deficienciess of the prior art, the utility model provides the switchgear that a kind of linkage is good, simple in structure
Cabinet door lock.
To achieve the above object, the utility model provides following technical solution：A kind of switch cabinet door lock, includes peace
Panel, the lock core in installation panel and the lock tongue to link with lock core are filled, is equipped with the linkage of the lock core and lock tongue
The gear to rotate in a circumferential direction with lock core, the lock tongue are to be engaged with gear and can be in the spacing of identical or opposite direction synchronous operation
Bar, it is characterised in that：The lock core is equipped with is equipped with drive rod for geared sleeve, offers what is be adapted to drive rod in the middle part of gear
Mounting hole, drive rod is equipped with diameter and is more than pinion mounting holes relative to being connected with lock core limit base at the other end of one end, tooth
Wheel is equipped with connector sleeve towards one end of limit base, and the extension block of drive rod extension is symmetrically provided with the inner wall of connector sleeve,
Drive rod, which is located to be equipped with the connector sleeve, can rotate at extension block and promotes the drive block of extension block.
Using above-mentioned technical proposal, lock core is implemented to link by drive rod and gear, and passes through between gear and drive rod
Drive block on extension block and drive rod in connector sleeve implements linkage, is screwed on without screw thread, will not go out in use
The phenomenon now loosened, and linkage is stablized, it is simple in structure.
The utility model is further arranged to：Torsional spring is equipped between connector sleeve and drive rod.
Using above-mentioned technical proposal, the setting of torsional spring can persistently provide driving force to connector sleeve, when lock core is implemented to drive,
Positive stop strip can be promoted to release locking, after lock core stops driving, positive stop strip can return back to lock position again.
The utility model is further arranged to：Gear is equipped with inserting groove towards the end face of connector sleeve, is set on connector sleeve
There is the grafting bar being adapted to inserting groove on gear.
Using above-mentioned technical proposal, so set connection structure compact, and be screwed on without screw thread, prevent from loosening.
The utility model is further arranged to：Positive stop strip includes two sections of connection straps shifted to install, two connection straps it
Between be connected by arcuation linking strip.
Using above-mentioned technical proposal, so setting can prevent positive stop strip from occurring situation about deforming in use.
The utility model is further described below in conjunction with the accompanying drawings.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model embodiment；
Fig. 2 is the structure diagram of lock tongue in the utility model embodiment.
Embodiment
