Abstract

The utility model relates to an electric control lock for an optical cable cross connecting cabinet, which requires no special unlocking tool and is simple to operate and high in safety. The electric control lock is characterized in that a movable fixture block and an electromagnet are arranged in a door lock main body; a locking lever is hinged on the door lock main body; a lock tongue is arranged at one end of the locking lever and forms a first lock catch together with a lock catch groove of the door lock; a restore lug boss provided with a groove at the side face is arranged at the other end of the locking lever and forms a second lock catch together with a second lock tongue of the movable fixture block; and a positioning leaf spring is arranged on the movable fixture block. When the lock is locked, a movable iron core of the electromagnet is inserted into a stop groove at the side face of the movable fixture block to position the movable fixture block. When to unlock the lock, the electromagnet is electrified to release the movable fixture block and then a rod-shaped object is inserted into an unlocking through hole at the side face of the door lock main body to push the movable fixture block to retract; after that, the second lock catch is opened and the locking lever can rotate, and the rotation of the locking lever enables the first lock tongue at one end of the locking lever to leave the lock catch groove, and then the first lock catch can be opened. In this way the lock can be unlocked.

Description

The fiber cable cross connection box electric control lock

Technical field

The utility model relates to a kind of electric control lock, particularly a kind of fiber cable cross connection box electric control lock that is used for communication or radio, TV and film industries.

Background technology

Along with the development of communication and broadcasting and TV cause, communications optical cable uses in a large number, thereby the quantity of fiber cable cross connection box is increased sharply, and the safety of fiber cable cross connection box and problem of management be day apparent giving prominence to also.The door lock of present existing fiber cable cross connection box all is that manufacturer carries, structure has nothing in common with each other, unlocking tool is multifarious, someone is provided with Cipher mechanism or adopts special-purpose key on the structure of lock, in the inspection process, often to be with multiple unlocking tool, operation also is not quite similar, and opens the door to the staff and brings very burden.Therefore, how to guarantee under the safe situation, unified unlocking tool, simplifying the operation course is the problem that communication and the expectation of broadcasting and TV enterprise solve.

Summary of the invention

Problem to be solved in the utility model provides a kind of special tool that need not and unblanks, and simple to operate, safe fiber cable cross connection box electric control lock.

The technical scheme that addresses the above problem is: the fiber cable cross connection box electric control lock that is provided comprises door lock body and the lock catch of door lock groove that is installed in respectively on door leaf and the doorframe, and special feature of the present utility model is:

In the door lock body, be provided with the active fastening block and the electromagnet of spring reset, be hinged with latched lever on the door lock body, an end of this latched lever is provided with first dead bolt, and it and lock catch of door lock groove constitute first snap close, the other end of latched lever is provided with the projection that resets, and this protruding side that resets is fluted;

Said active fastening block side is provided with locking groove, and the moving core of aforementioned electric magnet inserts in the locking groove of active fastening block side during blocking;

Said active fastening block is provided with the retainer spring sheet, and the projection that resets of latched lever is pointed to this retainer spring sheet, and the head of this retainer spring sheet withstood on the inwall of door lock body after active fastening block bounced back during unlocking condition, made the active fastening block location; This retainer spring sheet of protruding jack-up that resets of latched lever during blocking makes in the latch groove on this retainer spring sheet insertion door lock inner body wall;

Said active fastening block also is provided with second dead bolt, and second dead bolt constitutes second snap close with the groove of the protruding side that resets of aforementioned latched lever;

A side at the door lock body also is provided with the through hole of unblanking, and this through hole of unblanking points to active fastening block.

This electric control lock is when closure state, latched lever and door lock body close up together, this moment, second dead bolt and the reset groove of protruding side of latched lever on the active fastening block snapped together mutually, and first dead bolt and lock catch of door lock groove on the latched lever snap together mutually.In the time of need unblanking, administrative unit is according to the electromagnet coil power of request to electric control lock, and the moving core retraction of electromagnet is removed the constraint to active fastening block, makes door lock be in released state.The field personnel uses a club to insert in the through hole of unblanking of door lock body side then, promotes the active fastening block retraction, and second snap close between active fastening block and latched lever is untied, and removes the constraint to latched lever.First dead bolt that latched lever is rotated on its termination, back rotates thereupon, and throws off with the lock catch of door lock groove, and promptly first snap close is untied, and unblanks to finish.

The first above-mentioned dead bolt can be fan-shaped dead bolt, can utilize a hypotenuse of fan-shaped dead bolt to block the lock catch of door lock groove like this, with door closure.Further the measure of fastening is that a clamping leaf spring is set in the lock catch of door lock groove, and the first fan-shaped during blocking dead bolt is pressed on the clamping leaf spring, makes to close tightlyer.

Compare with existing electric control lock, the utility model is suitable for the various fiber cable cross connection boxes of communication, telecommunications industry.Because the utility model is provided with two snap closes that are mutually related, wherein second snap close is positioned at the body of lock, so shockproof, pick-proof good, safety is higher.Need not special tool when the utility model is unblanked, only need to use bar-shaped object to get final product, simple to operate, bring great convenience for the Maintenance and Repair personnel.The utility model can close the door of cross-connecting box very tight in addition, avoids dust and rainwater to enter.
