Description

Violence-preventing opening clutch device and lock with same

Technical Field

The utility model relates to a tool to lock technical field, in particular to clutch is opened to anti-riot power and has its tool to lock.

Background

The protective panel of the existing lock generally comprises a panel and a handle arranged on the panel, and the handle is screwed to further realize unlocking. When a lawbreaker opens a lock, a handle is usually twisted by violence, and a general electronic lock knob in the market at present needs to use a tool to twist violently because the lock is ensured to be destroyed violently, namely, under the condition that correct password authorization is not input, and in order to prevent the internal locking mechanism from being damaged to cause unlocking, a design of a rupture groove is used on the knob structure.

However, the above structure causes the knob to be permanently damaged when violently opened, and the lock function can be restored only by replacing the knob again, which causes inconvenience in use for users and increases maintenance cost; on the other hand, the anti-breaking process is not easy to be mastered in manufacturing, the breaking force of the knob breaking groove is influenced by the factors of materials, die-casting processing and the like, and the knob breaking groove breaks when not reaching the specified bearing force or exceeds the specified force and does not break to cause the damage and the unlocking of a locking mechanism in the lock, so that a certain risk exists when a user uses the anti-breaking lock.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a clutch is opened to anti-riot power has the security height, low cost, the strong effect of reliability. Another object of the utility model is to provide a tool to lock with clutch is opened to anti-riot power, have effect safe, convenient to use, good reliability.

The above technical purpose of the present invention can be achieved by the following technical solutions: an anti-violence opening clutch device comprises a lock cylinder assembly and a knob, wherein a clutch block is fixedly arranged on the lock cylinder assembly, and at least one group of symmetrically-arranged clutch grooves are formed in the clutch block along the circumferential direction;

at least one group of symmetrical clutch plug connectors are movably arranged in the knob through an elastic piece, and the clutch plug connectors are matched with the clutch grooves in a positioning mode;

be provided with guide structure between separation and reunion plug connector and the separation and reunion groove, when the knob rotated relatively the lock core subassembly, guide structure ordered about separation and reunion plug connector and taken off the separation and reunion groove.

By adopting the technical scheme, under the condition of normal use, unlocking can be realized by rotating the knob after unlocking; when adopting the violence to open under the abnormal conditions, illegal opener adopts instrument violence to rotate the knob, at this moment, under guide structure's guiding effect, make separation and reunion plug-in block receive revolving force effect extrusion elastic component and take off from the clutch groove, effect inefficacy along with the commentaries on classics between knob and the lock core subassembly, after separation and reunion plug-in components take off from the clutch groove, the knob can be relative lock core subassembly free rotation until the separation and reunion plug-in components correspond to another group's clutch groove once more, separation and reunion plug-in components insert in the clutch groove that corresponds under the elastic force of elastic component, again with lock core subassembly and knob locking. Therefore, the clutch grooves which are symmetrically arranged are matched with the clutch plug-in connectors in an inserting mode, so that the locking effect is more stable and reliable, an illegal opener cannot open the clutch plug-in connectors by violence, and the safety is higher; on the other hand, the device can also play a role in eliminating the will of illegal openers.
