Description
Technical field
This utility model relates to antitheft door technical field, specifically, relates to a kind of antitheft door and unblanks handle.
Background technology
nullExisting machinery formula safe-guard door lock mostly is rotary spring lock，Some marble holes on its lock core and lock body are the most corresponding，When lock is in locking or opening，Marble hole on lock core and lock body is connected with each other，These interconnective marble holes are built with inside and outside pellet and the marble spring being pressed on outer pellet top，When the key inserted does not matches with lock，One end of the outer pellet of part or interior pellet is positioned at the marble hole of lock core，The other end is positioned at the marble hole of lock body，Lock core is blocked，It is allowed to rotate，When inserting matched key，In outer, the connecting part of pellet is just at lock core and the joint of lock body，In i.e., pellet is positioned at the marble hole of lock core，Outer pellet is positioned at the marble hole of lock body，Rotary locking cylinder，Lock core is stirred dead bolt by toggle mechanism and is moved，Lock is opened，The defect of this lock is to need to use key rotation lock core，Suffered by key, torque is bigger，It is prone to fracture in lock core，Additionally，Owing to lock core and the shell of this lock are splits，Lock core end face is exposed at outdoors，It is prone to be destroyed by external force，Bigger fit tolerance it is also required between lock core internals，It is prone to illegally be opened.
During how avoiding key unlocking, spinning force is excessive, fractures in lockset, is the direction of following lockset development.
Utility model content
The technical problem to be solved in the present invention is a kind of simple in construction of design, reasonable in design, rotarily opens lockset by handle, it is to avoid key rotates and fractures in lock core.
For solving the problems referred to above, this utility model be the technical scheme is that a kind of antitheft door is unblanked handle, including doorframe, is provided with door in described doorframe, it is characterized in that: described door is provided with lock core, being socketed with snap close on lock core, described snap fit is provided with groove, and described groove is located on torsion bar, it is additionally provided with cam on described torsion bar, described cam one end is socketed with ring, and torsion bar is provided with handle near one end of ring, and described ring is hinged with connecting rod.
A kind of improvement as technique scheme: described torsion bar is provided with guide rod away from one end of handle, and described guide rod is socketed with baffle plate, and guide rod is provided with stud near one end of baffle plate.
