The utility model discloses only need to rotate the key and make lock core rack (23) intersect with spring bolt gear drive pole (22) after rotate handle (1) just can lock, vice versa, therefore have spring bolt insurance apart from long, the theftproof performance is good, the handle rotates, the key load is little, convenient to use, advantages such as extensive applicability.
Description
The utility model relates to a kind of door lock, especially a kind of rolling door mechanical anti-theft lock.
Existing Rolling door lock is opened and the pass is directly to be rotated by key, and the core driving wheel drives driven pulley and promotes the dead bolt tooth bar, and this lock has following deficiency: 1. long because of the dead bolt of rolling door own, frictional resistance is big, and the key load is heavy, locks perishable.2. the dead bolt safety plug is short and small, and the longest degree of depth is less than 30mm, locks not firm, untrustworthy.If 3. on existing basis, only extend, strengthen dead bolt, key more can promote difficulty.4. tapered end exposes near outdoors 10mm, is prized by the pipe wrench destructiveness easily.
The utility model aims to provide and a kind ofly can increase dead bolt length as required, allow it reach best pick-proof position and need not directly to use key, but the armrest handle promotes the long-lived rolling door mechanical anti-theft lock of dead bolt.
Below in conjunction with accompanying drawing the utility model is described in detail:

The utility model comprises lock box (20), core (13), handle (1), core gear (27), core gear-box (19), core tooth bar (23), dead bolt gear-driving rod (22), trivial hyoid tooth wheel (15), left dead bolt tooth bar (16) and right dead bolt tooth bar (9), its characteristics are:
1, dead bolt pinion stand (14) is welded on the lock box (20), at dead bolt pinion stand (14) dead bolt gear Add butter on the position and reduce dead bolt gear (15) to the friction of dead bolt pinion stand (14), dead bolt gear (15) dress After upper, also cap (17) and back-up ring (18) are installed, attention will guarantee that the certain interval of dead bolt gear (15) joins Close, dead bolt gear (15) is rotated flexibly at dead bolt pinion stand (14).
2, right dead bolt tooth bar (9) is z shape, its top and the engagement of dead bolt gear (15) upper end, the lower end engages of left dead bolt tooth bar (16) and dead bolt gear (15).When dead bolt tooth bar recess and the self-locking of dead bolt alignment pin, dead bolt gear-driving rod (22) must be vertical with dead bolt position-sensing switch pin, just unblanks.
3, two core gears (27), two groups of core tooth bars (23), dividing plate (25), steel ball (26) the core gear-box (19) of packing into simultaneously, with electric welding welding core gear-box (19) and case lid (24), more left tapered end (2) and right tapered end (10) are welded on core gear-box (19) both sides.
4, left tapered end (2), right tapered end (10) and core gear-box (19) fuse, and are contained on the lock box (20) by dead bolt pinion stand (14) hole.Again handle (1) is contained on the right tapered end (10).Be connected and fixed with screw (1).
5, in the middle of cover plate (4), load onto protective sleeve (3), cover plate (4) is connected on the lock box rest pad (21), again another lock handle (1) is contained on the left tapered end (2) with sunk screw (5).
6, at lock box (20) welded top dead bolt tooth bar position-sensing switch seat (6) and position-sensing switch clamping plate (8).Position-sensing switch (7) is contained on the dead bolt tooth bar switch base (6).
Its using method is:
The red point of tapered end upwards inserts right tapered end (10) with key by dustproof door (12), and dextrorotation is circled.Core gear (27) promotes core tooth bar (23), it and dead bolt gear-driving rod (22) are intersected, rely on dead bolt gear (15) to drive dead bolt tooth bar (9) and dead bolt tooth bar (16) by rotating counterclockwise handle this moment, and two dead bolts are successfully shifted best antitheft position onto toward both direction.By clockwise rotating handle, original position is got back in dead bolt tooth bar (9), (16), again key by being rotated counterclockwise a week, transfer to key, the core tooth bar (23) of core gear-box is got back to original position simultaneously, and core tooth bar (23) separates with dead bolt gear-driving rod (22), handle has become neutral state, rotate in any case and all be with motionless dead bolt gear (15), dead bolt tooth bar (9), (16) just more can not moved.Attention: when unblanking, key turns must be transferred to key after one week, and when anti-core tooth bar (23) intersected with dead bolt position-sensing switch (7), the pressurized influence made core tooth bar (23) self-return.
The utility model also can be changed the back slightly and be used as an one mutation with existing driven pulley (30) and the dead bolt tooth bar of locking (28), concrete structure is: 1. at cover plate (4) lower end position electric welding driven pulley splicing sleeve (32), dress steel ball (31) in splicing sleeve (32), follower shaft (30) is packed in the splicing sleeve (32), again dead bolt (28) is contained on the driven tire (29).
2. removing right dead bolt tooth bar (9) and left dead bolt tooth bar (16) replaces with dead bolt (28).With dead bolt gear (15) is that driving wheel drive driven pulley (30) promotes dead bolt (28), and other structure is constant.
Method for unlocking: the red point of tapered end upwards, insert core (13) with key by dustproof door (12), circle by dextrorotation, making core gear (27) promote core tooth bar (23) intersects with dead bolt gear-driving rod (22), this moment, turning handle relied on dead bolt gear (15) to promote the purpose that dead bolt (28) reaches the dead bolt open and close for driving wheel drives driven pulley (30).
The utility model and mutation thereof have following advantage:
1, this lock dead bolt frictional resistance can not influence key.
2, dead bolt insurance distance, theftproof performance is good.
3, handle rotates, and key is zero load, durable.
4, this lock also can be prevented the destructive picking lock of pipe wrench.
5, rolling door mostly outside, this lock is equipped with waterproof, and is dustproof, anti-thefting facility.
6, easy to use, applicability is wide.
