Description

Reset lock

Technical field

The utility model is related to cabinet door lock, is that a kind of reset is locked.

Background technology

Cabinet door lock is a kind of lockset applied to electric cabinet door, and cabinet door lock is less demanding to the security performance of lock, the behaviour of lock Make without too complicated, mainly prevent power supply unit exposed, occur emergency episode and unlock conveniently, it is general to use plane single-point lock, Key insertion can open cabinet door.Such cabinet door lock had both reached the purpose of safety, again with handling well, occurred urgent Situation is unlocked also more convenient.Existing such cabinet door lock, the application number 201220074178.7 as disclosed in Chinese patent literature, Authorized announcement date 2012.10.10, utility model title " the locking safety lock of locking type "；The locking gear ring of the locking safety lock leads to The external diameter that nut screws in pedestal is crossed, nut is provided with holding screw；Lock core screws in the internal diameter of pedestal, provided with close between lock core and pedestal Seal, the base end of lock core is provided with locking bolt or dead bolt；Its main points is that the key end external diameter of the lock core is provided with neck, elastic collar While being inserted in pedestal internal diameter, the claw of elastic collar and straight pawl end are engaged with the neck of lock core；Straight pawl is justified with claw interval Shape is arranged, and the claw of elastic collar is retracted from key end to base end step, and elastic collar and positioning seat pass through hole back-up ring It is fixed on the internal diameter of pedestal.But above-mentioned cabinet door lock is not directed to auto-reset function, the existing similar cabinet with auto-reset function Door latch structure design is complicated, and Assembling Production is more inconvenient, and it is more inconvenient that key forms a complete production network, and the structure such as anti-return needs further Improve and perfect.

The content of the invention

To overcome above-mentioned deficiency, the purpose of this utility model is to provide a kind of reset to this area to lock, and makes its solution existing The design that automatically reset in like product is not good enough, and production, assembling inconvenience, and coupling mechanism force are poor, the skill that anti-return security is not good enough Art problem.The purpose is to what is be achieved through the following technical solutions.

One kind resets lock, and the lock core of reset lock is inserted in the lock core hole of pedestal, and lock core is limited by the limiting stand of lock core one end In pedestal, the suit place of lock core and pedestal is provided with torsion spring, and the spiro rod section of the pedestal internal cylinder other end stretches out pedestal, the end Lock core is fixed by pin and is limited in pedestal, and pedestal, lock core, torsion spring are connected as a single entity, and the external part of lock core is provided with steel bolt, steel bolt Lock core is fixed in one end by locking nut, and the outer-diameter threads section of pedestal is sequentially provided with pad, lock washer and installs nut, base The lock core hole edge external diameter of seat is provided with spacing hole edge；Its structure design main points is the limiting stand inner diameter central of the lock core provided with convex Ring recess is provided between the interior switch block risen, the inner diameter wall of interior switch block and limiting stand；Fastened with a bolt or latch provided with lock core the limiting stand side on torsion spring top Hole, the door bolt being arranged in lock core bolt hole is limited in pedestal latch aperture by fastening the pedestal latch aperture of spring section stretching pedestal with a bolt or latch, and offseting The inwall at place；Key is inserted in the ring recess of lock core, and is engaged simultaneously with interior switch block, door bolt, and the pedestal latch aperture of door bolt and pedestal departs from, and rotates Key, drives steel bolt to rotate by lock core.As long as door bolt meets key insertion lock core, fasten with a bolt or latch to lock core contract, make door bolt and pedestal Disengaging；It uses following door bolt and the structure of lock core one, and door bolt is pushed using key, drives door bolt to contract；Or key Specified channel is engaged with door bolt concaveconvex structure, drives door bolt to contract.

The door bolt in the limiting stand and interior switch block of lock core side, when key is inserted in interior switch block, fastens spring with a bolt or latch simultaneously The ring recess is constituted between deformation, the inner diameter wall of interior switch block and limiting stand, the interior switch block of door bolt and lock core constitutes overall interior switch block.

The interior switch block of the lock core is truncated rectangular pyramids, when door bolt spring is deformed upon, and the interior switch block of door bolt and lock core constitutes truncated rectangular pyramids. Above-mentioned truncated rectangular pyramids are a kind of positive terrace with edge structure, facilitate the interior switch block stable engagement of key and lock core, reduce and key is added Work requirement.

The key is provided with spanner for the sleeve side of Key jaw type spanner, i.e. Key jaw type spanner, and Key jaw type spanner is in L-shaped.So as to It is easy to operation lock core to rotate, and drives steel bolt to rotate by lock core.

The other end of the steel bolt is to the lock core hole side lifting of pedestal, and the end both sides edge of steel bolt sticks up to opposite side Rise.Consequently facilitating the locking when rotating of steel bolt imports corresponding door-plate OR gate frame, and more stablize when locking.

The cork cot of the lock core is provided with skirt edge along external diameter, and the skirt of lock core is fitted along with the spacing hole of pedestal edge, lock core Skirt is along provided with display fenestra and arrow, and the spacing hole of the display fenestra correspondence pedestal on skirt edge is along provided with position instruction mark. So as to when key band movable lock core rotate when, be clearly apparent from the reset lock state in which, and Key operation side To instruction.

The limiting stand side of the lock core is provided with positioning hole, and positioning hole is located at below lock core bolt hole, is arranged in positioning hole Steel ball offseted by the inwall of steel ball spring and pedestal.Said structure makes lock core have damping to feel in rotation, and further steady Setting of the fixed lock core in pedestal.

The inwall of the pedestal is provided with steel ball hole, when lock core turns to open mode, and steel ball is pushed up under steel ball spring effect Enter the steel ball hole of pedestal.So as to which when the reset is locked in open mode, due to the positioning of steel ball, lock core is more difficult automatic by torsion spring Return.

The protruding side end of the lock core is provided with split pin.Split pin is used to further prevent steel bolt on lock core, locking Nut drops.

The utility model reasonable in design, production cost is low, using, it is easy to assembly, stability, security are good；It is fitted Cooperate to need the cabinet door lock of auto-reset function to use, and the structure of like product is improved.
