Abstract

The invention discloses a cabinet lock. The cabinet lock comprises a lock body, a heaven and earth rod, a locking plate, a handle and a shifting lever. The handle is arranged on the outer end face of the lock body in an embedded mode. The upper end of the handle is hinged to the shifting lever through a plug pin. A lock cylinder is installed on the inner surface of the lower end of the handle. A bolt rotating along with the lock cylinder is correspondingly arranged at the inner end of the lock cylinder. A first magnetic induction component, a second magnetic induction component and a circuit board are arranged in the lock body. The first magnetic induction component comprises a first coil, a first framework and a first iron core. After the first iron core stretches out, abutting limiting is formed between the first iron core and one radial end of the bolt so that the lower end of the handle cannot be lifted upwards by being hinged. An induction part is arranged at the other radial end of the bolt. A Hall component is correspondingly arranged on the circuit board and is opposite to the front face of the induction part and induction matching is formed between the induction part and the Hall component. By the adoption of the structure, the cabinet lock is good in antitheft performance.

Description

Machinery cabinet lock

Technical field

The present invention relates to field of lockset, be specifically related to a kind of machinery cabinet lock.

Background technology

At present, the common existence of existing machinery cabinet lock be more easily unlocked, the defect of theftproof performance difference.

Summary of the invention

For the deficiencies in the prior art, the invention provides the good machinery cabinet lock of a kind of theftproof performance.

For achieving the above object, the invention provides a kind of machinery cabinet lock, include lock body, universe rod, locking plate, handle and driving lever, described driving lever is arranged on lock body, the inner of driving lever and locking plate and universe rod link, the outer end radial direction of driving lever wears and is fixed with latch, described handle is flush-mounted on the outer face of lock body, upper end and the described latch of described handle are hinged fixing, and by hinged rotation, the lower end of handle upwards can be lifted and is separated with lock body, the lower end inner surface of described handle is equiped with lock core, on the lower end external surface of described handle, correspondence is provided with the through hole be connected with lock core, on the inner end of described lock core, correspondence is provided with the dead bolt playing rotation with one, the first magnetic strength assembly is provided with in described lock body, the first described magnetic strength assembly includes the first coil, first skeleton and the first iron core, the first described skeleton is installed on lock body, the first described coil is set around on the first skeleton, the first described iron core is located in the first skeleton, the wiring board for controlling the first iron core expanding-contracting action is also provided with in described lock body, and described first iron core formed with radial one end of described dead bolt after stretching out force the lower end of handle cannot by hinged upwards lift abut spacing, the radial other end of described dead bolt is provided with induction pieces, on described wiring board, correspondence is provided with described induction pieces vis-a-vis and forms at it Hall subassembly responded to and coordinate each other, also be provided with when described induction pieces is with the second magnetic strength assembly being controlled by wiring board when lock core rotation is rear and described Hall subassembly loses induction to trigger in described lock body, the second described magnetic strength assembly includes the second coil, second skeleton and the second iron core, the second described skeleton is installed on lock body, the second described coil is set around on the second skeleton, the second described iron core is located in the second skeleton, on described handle, corresponding being provided with to form grafting and joins to be incorporated in and to force the lower end of handle cannot by the hinged jack upwards lifted after grafting coordinates after the second iron core stretches out with the second iron core.

The invention has the beneficial effects as follows: adopt said structure, under normal power-up state, wiring board controls the first iron core and stretches out, and with radial one end of described dead bolt formed force the lower end of handle cannot by hinged upwards lift abut spacing, now machinery cabinet lock is in normal locking state, people want to open machinery cabinet lock, triggering line plate can only be carried out by the external electronic device set in advance, make wiring board control the first iron core to retract, after this people just upwards lift the lower end of handle by hinged rotation, the lower end gripping handle again drives driving lever to rotate, locking plate and universe rod also will follow rotation, machinery cabinet lock is normally opened.And under above-mentioned normal power-up state, people cannot realize unblanking by the lock core on illegal swing handle, its principle is: although lock core rotates, the dead bolt be connected with lock core also can and then rotate, thus dead bolt is lost to match with the first iron core to force the lower end of handle cannot by hinged upwards lift abut spacing, while but lock core rotates, induction pieces also can be driven to rotate, and described induction pieces will lose the induction effect with Hall subassembly after rotating, now wiring board is by the action of triggering second magnetic strength assembly, even if the second iron core stretches out and is inserted in the jack of handle, after this lower end of handle still upwards cannot be lifted by hinged rotation, handle cannot rotate, i.e. described driving lever, locking plate and universe rod also cannot and then rotate, therefore cannot realize unblanking.And only under the emergency ratings such as power-off, wiring board cannot work, the lock core that people just can be come on swing handle by key realizes unblanking, because wiring board cannot work, therefore the second magnetic strength assembly action would not also be triggered, second iron core also would not stretch out and be inserted in the jack of handle, as long as thus dead bolt loses after rotating with lock core to match with the first iron core and forces the lower end of handle cannot be spacing by abutting of upwards lifting of hinged rotation, people just upwards can lift the lower end of handle by hinged rotation, the lower end gripping handle again drives driving lever to rotate, locking plate and universe rod also will follow rotation, machinery cabinet lock will be unlocked.

In sum, due under above-mentioned normal power-up state, people can only be carried out triggering line plate and realize unblanking by the external electronic device set in advance, and cannot realize unblanking by the lock core on illegal swing handle, and therefore theftproof performance significantly promotes.

On the outer face that the present invention can be set to described handle further, also hinged being fixed with can form to the through hole that it is connected with lock core the tapered end cover hidden.By arranging tapered end cover, described tapered end cover can be made when not unblanking to cover in the through hole that handle is connected with lock core, thus not only effectively avoid external dust etc. to enter in lock core by this through hole, and after hiding, the monnolithic case of machinery cabinet lock also becomes more elegant in appearance.

The present invention also can be set to the second described skeleton further and also be covered with outer casing outward, and is also provided with the silica gel for sealing between described outer casing and the second skeleton and between described wiring board and lock body.Adopt said structure, set up outer casing, after can effectively avoiding the lower end of handle upwards to be lifted by hinged rotation, the second skeleton is outside exposed, and the silica gel all arranged between described outer casing and the second skeleton and between described wiring board and lock body for sealing, then greatly can promote overall sealing performance and the water resistance of machinery cabinet lock.
