The door bolt lever structure is adopted, and the door bolt is directly controlled by the lock core; the utility model relates to a large door locking device which has the advantages simple structure, easy locking, anti-identifying and anti-prizing performance, and high safety, and can be widely used for workshops, storehouses and yards.

Description

The large-scale Locking means of door of lever

The utility model relates to Locking means of door, and definite saying so discloses the large-scale Locking means of door of a kind of lever, belongs to the mechanical door lock technical field.

Existing large-scale door (as gates such as warehouse, workshop, gardens) locking device is that door is pinned with keeper, again with the common lockset bolt of locking the door; Or with chain door chain is lived, again on the chain lock; Said method troublesome poeration effort, and keeper, chain be exposed to outdoors, and lockset or chain are easy to be destroyed, and illegally open gate, poor stability.

Task of the present utility model provides the large-scale Locking means of door of a kind of lever, and purpose is that the lockset that overcomes the tight device of existing door is subject to destruction, shortcomings such as poor stability.

The solution of finishing the utility model task is as follows: this device comprises that lock body, lock core, tapered end, keeper constitute, wherein, lock core is located on the lock body, have positioning groove on the tapered end, keeper is that leverage one end is hinged on the lock body, and be connected with back-moving spring, and the other end is that the positioning groove on crotch body and the tapered end is connected, the middle part of keeper is provided with the dead bolt formation engagement of castellated plates and lock core and pays;

During use keeper is pressed, its top is buckled in the positioning groove of tapered end, turn lock core the castellated plates of dead bolt and keeper is meshed, restriction keeper reset movement, lock body and tapered end can not relatively move, reach the gate locking function, when opening lock, turn lock core and make the castellated plates of dead bolt and keeper break away from engagement, keeper moves up under the effect of back-moving spring, hook body and positioning groove break away from, and lock body and tapered end can relatively move.

Good effect of the present utility model is: adopt the keeper leverage, directly control keeper by lock core, keeper and lockset are one, it is convenient to open, and can be installed in the inboard of door, has effectively avoided keeper, door lock destroyed, simple in structure, anti-other pick-proof, safe and reliable, can be widely used in the large-scale door locking device of workshop, warehouse, garden.

Fig. 1 is the utility model structure principle chart.

Further specify the utility model below in conjunction with accompanying drawing: in Fig. 1, utilize lever principle keeper 7 to be hinged on the lock body 3 by pin 4, its tail end is connected with the fixed mount 1 of lock body 3 through back-moving spring 2, the middle part of keeper 7 is provided with dead bolt 10 engagements of castellated plates 9 and lock core 5, front end is a hook body 11, can be connected with the positioning groove 12 of tapered end 8, lock core 5 is located on the lock body 3 corresponding with castellated plates 9 positions of keeper 7, has positioning groove 12 on the tapered end 8.
