Description

Rolling-gate list hook pick-proof automatic locking

One, technical field

The utility model relates to a kind of rolling gate door lock, and especially a kind of rolling-gate list hook pick-proof automatic locking is suitable for any rolling-gate window and uses.

Two, background technology

Known rolling gate door lock by lock core, housing, gear, guide strip, lock hook axle, encircle institute and form, can open and close with key and lock, but have problems such as lock body length, complex structure, cost height, theftproof performance difference.

For addressing the above problem, Chinese patent notification number 2636241 discloses a kind of " single hook burglary-proofing lock for rolling door ", it is to be with gear at lock core simultaneously to establish an eccentric wheel and an auxiliary catch, can improve the pick-proof performance, but when it exists rolling-gate to close, must lock with key, so that operate problems such as cumbersome.

Develop for this reason a kind ofly can automatically lock, rolling-gate list hook pick-proof automatic locking easy and simple to handle just mentioned on the innovation schedule.

Three, summary of the invention

The purpose of this utility model provides a kind of rolling-gate list hook pick-proof automatic locking that solves the known technology deficiency, and it can automatically lock when leaving behind rolling-gate.

For achieving the above object, the scheme of the utility model design comprises: lock core, housing, guide strip, lock hook axle, latch hook, spring, encircle, it also comprises: hinge, locating shaft, left tooth bar, right tooth bar, eccentric gear, driven wheel, half gear, clockwork spring, half gear shaft, trigger, trigger member, safety plate; Described eccentric gear be establish in the eccentric ring outside one only block post, a gear is established in the inboard, eccentric gear, driven wheel is inserted in successively the lock core that is fixed in housing; Be engaged on the gear of eccentric gear inboard under described left tooth bar and right tooth bar one end, successively the stage casing of guide strip, the latch hook that is inserted in the eccentric gear eccentric ring, safety plate is positioned the housing bottom below with lock hook shaft, the same plane of driven wheel and safety plate, safety plate upper end bayonet socket or driven wheel left side breach fall into only blocking on the post of eccentric gear alternatively; Half gear of described superimposed clockwork spring is positioned the housing bottom both sides with half gear shaft, and the clockwork spring outer end connects half gear locating shaft, and left tooth bar, the right tooth bar other end are engaged in half gear down respectively; Described safety plate lower end connects the locating shaft of housing bottom below with spring; Be fixed under the tooth bar of a housing bottom left side with locating shaft in the middle of the described trigger, be inserted in the hinged trigger left end in trigger member upper end of housing bottom, trigger right-hand member breach can block puts left tooth bar convex shoulder.

The utility model automatically locks so can land because be provided with trigger member and half gear spring reset components; Simultaneously owing to being provided with eccentric gear, driven wheel and safety plate, so theftproof performance is better; Do not change single hook burglary-proofing lock for rolling door basic structure owing to lying in addition, so structure is still simple.
