Abstract
The utility model discloses a quick and safety theftproof door lock which can finish the whole process of a safety theftproof lock door without a key. The utility model which belongs to the technical field of the production of locks is composed of a lock body 1, a lock head 4, a driving sheet 3, a hook shifting hole 10 and a key 5. The utility model is characterized in that an intermittent rotary mechanism of a gear and a ratchet wheel surpassing type unidirectional mechanism are installed between the lock head 4 and the lock body 1, and the ratchet wheel surpassing type unidirectional mechanism is composed of a ratchet wheel 7 and a pawl 8; the ratchet wheel 7 is connected to a wheel shaft of a driven wheel 9 in parallel, and a driving gear 2 is engage with the driven gear 9. The safety theftproof door lock of the utility model can quickly finish the whole process of locking a door and shorten the required time for locking the door.
Description
The utility model discloses a kind of quick safety anti-theft door lock, need not just can finish the antitheft overall process of locking a door of insurance, belong to the lock technology production field with key.
At present, existing safety anti-theft door lock will make antitheft Square lock bolt stretch out, just need use key, and usually will be with two weeks of key turns, preceding some time of the working that makes many people just be of great value originally becomes ground and gets more nervous, thereby cause many people because of there isn't enough time, do not lock Square lock bolt.Do not want to take the trouble when having many people to come off duty and do not lock Square lock bolt, thereby reduced its antitheft usefulness.
The purpose of this utility model is that a kind of improved quick safety anti-theft door lock will be provided, and just can promptly antitheft Square lock bolt be stretched out without key, finishes the time of locking a door thereby reduce safe-guard door lock.
Task of the present utility model is by to comprising by lock body 1, tapered end 4, driver blade 3, dialling the improvement that dog hole 10, key 5 constitute door lock and finish, it is characterized in that: a gear intermittently rotating mechanism and the unidirectional mechanism of ratchet override type are installed between tapered end 4 and the lock body 1, and the unidirectional mechanism of ratchet override type links to each other with outdoors swing handle 6.Said gear intermittently rotating mechanism is made of driving gear 2 and driven gear 9 engagements, one arc gap is arranged on the driving gear 2, the unidirectional mechanism of ratchet override type is made up of ratchet 7 and ratchet 8, and a ratchet 7 in parallel on the wheel shaft of driven opinion 9 is connected as a single entity by ratchet 8 and swing handle 6.
The good effect that the utility model is created is:
1. make the safety anti-theft door lock can promptly finish the overall process of locking a door.Reduce the trouble of locking a door, shortened the needed time of locking a door.
2. mechanism is simple, and is effectively reliable.
Describe content of the present utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is a schematic diagram of mechanism of the present utility model
Fig. 2 is the intermittently schematic diagram of rotating mechanism of gear of the present utility model.
See Fig. 1, the utility model rapid safety safe-guard door lock. Lock body 1, tapered end 4, transmission Sheet 3, dial dog hole 10, key 5, by driving gear 2 and driven gear 9 consist of not exclusively Intermittent rotating mechanism is by ratchet 7, ratchet override type one-way mechanism that ratchet 8 consists of and revolve Handle 6 connects. See Fig. 2, driving gear 2 and driven gear 9, key shown in the figure 5 withdraws from shape Attitude, the circular arc cutaway on the driving gear faces driven gear 9 at this moment, and driven gear 9 is not Limited by driving gear 2 can Free.
Exemplify most preferred embodiment below in conjunction with accompanying drawing.
Fig. 1 is most preferred embodiment figure of the present utility model, and a driving gear 2 and driven gear 9 are installed between tapered end 4 and lock body 1, ratchet 7 in parallel and ratchet 8 on the wheel shaft of driven gear 9, and swing handle 6 is installed on the ratchet 8.Swing handle 6 is outdoors, and ratchet 7 and ratchet 8 have guaranteed that swing handle 6 can only lock a door and can not open the door.Its transmission process is: key 5 drives transmission 3, and driver blade 3 drives driving gear 2 again, and key 5 revolutions move a week, and driving gear 2 just drives driven gear 9 and rotates a week.Thereby can finish the everything that opens the door and lock a door that existing safety anti-theft door is locked with key 5.When key 5 is in exit status, driving gear 2 and driven gear 9 are in key 5 and withdraw from the position, swing handle 6 outdoors can only rotate driven gear 9 towards the direction of locking a door by ratchet 7 and ratchet 8, thereby Square lock bolt 11 is stretched out, and finishes the overall process of locking a door of quick safety anti-theft door lock.If in rotating swing handle 6 just suitable prior aries outdoors, lock a door with key.
