Description
Technical field
The present invention relates to a kind of lock for safe.
Background technology
Along with people's living standard constantly improves, enriching gradually of assets, the application making safety cabinet is also more and more extensive, and the pick-proof performance of safety cabinet is also become better and better, but the aspect such as to arrange of existing safety cabinet cabinet lock still exists the place that can improve.
In prior art, in prior art, Chinese patent literature CN2331747Y discloses a kind of safety cabinet.Comprise cabinet, doorframe, door leaf, handle, door lock.Handle is equipped with door leaf, lock, combination disk.Install in the recessed doorframe of door leaf.There is free bearing at the back side with door leaf, and doorframe has free bearing, and hinge coordinates with free bearing.The shift fork bolt of automatic locking apparatus and handle are connected, it there is the pin hinge on elongated slot and towing plate, move handle, rotating an angle can make shift fork stir towing plate horizontal movement, to lock a door dead bolt seat and horizontal dead bolt thereof retracts, and drive dihedral toggle to rotate around the axle be fixed on door leaf by pin, vertical dead bolt is retracted, to reach the object of enabling at vertical direction.Towing plate is in the process retracting dead bolt seat, and the pressure that spring is subject to constantly increases, and force stop to be stuck on the seam of towing plate, all lock door mechanisms are locking, and door can be opened.When again at closing time, with hand, door leaf need only be pushed doorframe.The last several millimeters of strokes of doorframe are entered at door leaf, the gap of door leaf and cabinet sidewall is constantly reduced, at this moment the push rod be contained on stop is under pressure, to arrow direction, stop is pushed, and lift dop and depart from seam, towing plate is under the elastic force effect of spring, drive dead bolt seat to move to the right, make front, side dead bolt to latched position.The safety cabinet of the prior art, the dead bolt in front is at least three, and is uniformly distributed, and the dead bolt of two sides is respectively one.
Above-described a kind of safety cabinet, there is following shortcoming: in the prior art, plunger on horizontal direction and vertical direction passes through towing plate, drive installation level put plunger seat upwards to drive level put to plunger lock out, meanwhile, the plunger on vertical direction is driven to lock out by the both sides of plunger seat by dihedral toggle.Due to towing plate driving is in the middle part of plunger seat, the both sides of plunger seat easily occur tilting, and in order to lock out laborsaving and save material, towing plate can not arrange too wide, therefore, drive pin headstock entirety in the middle part of plunger seat is had easily to cause plunger seat both sides to tilt, particularly for highly higher safety cabinet, it is very long that its plunger seat generally can be arranged, and multiple horizontal plunger can be set, make plunger seat both sides tilt so more obvious, easily cause plunger to run underaction, unblank or locking feel poor, even have influence on and lock out smoothly or retract.
Summary of the invention
The plunger seat that the object of the invention is to the lock for safe installation plunger overcoming prior art easily causes plunger seat both sides to tilt by midway drive, lock out jiggly problem, thus provide the simple letter of a kind of structure to gather, lock out stable lock for safe.
