Abstract

The utility model relates to a gear buckling lock. An edentulous gear is concentrically sheathed on a lock core. A toothed lock bolt pulled by a spring and arranged in a lock pipe can be engaged with the gear. Thus, when the lock is unlocked, the toothed lock bolt and the gear are not engaged, when the lock is locked, the toothed lock bolt and the gear are engaged. One side of the gear is also provided with a plurality of friction slots, and elastic contact heads are pressed on the friction slots. When the lock is locked, the friction slots play a back stopping function to the lock bolt and a positioning function to the lock bolt after the lock is unlocked. The gear and the toothed lock bolt of the utility model can be separated and closed, and the problem that a key rotates with the gear in the prior art is solved. The lock can be unlocked and locked by using the key rotating operation of one hand to be convenient for use.

Description

Hasp lock with gear

The utility model belongs to lock field, particularly padlock.

Padlock in the prior art, as the sprocket wheel of bicycle lock: a kind of have a Wrench-type, must lock by spanner, extract key again, the wrench seam has reduced the mechanical performance and the pick-proof of whole lock construction, another kind is a gear type, bicycle lock described in z188201371, by lock core, pinion, lock housing and band tooth locking bolt are formed, at pinion, a spring is installed between the lock housing, is made key only rotate 90 degree and just can open or close lock by spring force, but, the back of the hand phenomenon appears hitting in the also and then rotation of other annexes on this key and the key ring, uses inconvenient, also has the gear lock of selling on a kind of market, also need to unblank by next button except that opening the lock with the key, other annexes also can and then rotate on key and the key ring, use very inconvenient.

The purpose of this utility model is to design a kind of Hasp lock with gear easy to use, that use key gauge tap lock.

The utility model comprises lock core, gear, lock pipe and band tooth locking bolt, gear is enclosed within on the lock core with one heart, be contained in the lock pipe band tooth locking bolt can and gear mesh, have in the gear one section anodontia, make that band tooth locking bolt is with gear is not meshing, be with tooth locking bolt and gear mesh when shutting when unblanking; Have spring to fixedly connected with band tooth locking bolt in the lock pipe, the elastic force of spring makes the quick indentation lock housing of band tooth locking bolt; One side of gear also is provided with a plurality of frictional grooves, and flexible contact is pressed on the frictional groove, and frictional groove plays the role of positioning to lock core after band tooth locking bolt is played non-return and unblanks when shutting.

The utility model switch lock is convenient, and when shutting, to the feel resistance when maximum, expression shuts action and finishes, and key can be taken out (when not putting in place, key is got to be come out) with the big half-turn of key rotary locking cylinder; When unblanking, key is inserted in the lock core, also with low-angle of above-mentioned same direction of rotation rotation, be have in the gear one section anodontia partial rotation to the meshing zone of band tooth locking bolt, band tooth locking bolt and gear are not meshing, band tooth locking bolt quick indentation lock housing under the elastic force effect of spring, key this moment motionless (because gear is motionless), key can not be pulled out yet, so when using, need only screw key always, just can unblank, shut, unblank, shut ... go on, one-handed performance, the convenient use.

Below in conjunction with accompanying drawing most preferred embodiment is described in detail:

Fig. 2: I portion partial enlarged drawing

Fig. 3: frictional groove A-A sectional drawing

Fig. 4: frictional groove B-B sectional drawing

Fig. 5: C-C direction structure schematic diagram among Fig. 1 (replenishing spring contact, tapered end etc.)

Fig. 6: unblank Shi Suoguan and band tooth locking bolt location diagram

Fig. 7: unlocking condition figure

As shown in Figure 1: gear 1 is enclosed within on the lock core 2 with one heart, and the band tooth locking bolts 4 that are contained in the lock pipe 5 can be meshing with gear 1, have in the gear 1 one section anodontia, the number of teeth of institute's hypodontia is decided according to the shape and the gear diameter of practical application locking bolt; Band tooth locking bolt 4 is meshing with gear 1 when shutting; Have spring 6 to fixedly connected with band tooth locking bolt 4 in the lock pipe 5, the elastic force of spring 6 makes in the band tooth locking bolt 4 quick indentation lock pipes 5; One side of gear 1 also is provided with a plurality of frictional grooves 3.

As Fig. 2, shown in Figure 3: two inclined-planes intersect forms frictional grooves 8 (cross section resembles V-arrangement), because the position of frictional groove 8 is more special, promptly be when shutting on the gear 1 last tooth 7 right frictional groove, so the angle a of frictional groove 8 is less than angle b, shut when putting in place feel more obviously to increase frictional force, just to make; Frictional groove also can be other shape, as semicircle, arc, polygon etc.When shutting, each frictional groove plays the non-return effect to band tooth locking bolt 4, even band tooth locking bolt 4 is to a direction

As Fig. 2, shown in Figure 4: other any one frictional groove 3 is also intersected by two inclined-planes to be formed, and just its angle b1 equates with angle b2, rotates to make things convenient for gear 1.

As shown in Figure 5: the spring contact 9 that produces elastic force by spring 11 is pressed on the frictional groove 3, tapered end 10 wraps on the lock core 2, one side of gear 1 is provided with a plurality of frictional grooves 3, on the position of lock pipe 5 below gear 1 inwardly recessed one section, to form stop bit 12, can when unlocking condition, stop the 4 excessively withdrawals of band tooth locking bolt.Stop bit can adopt other form, as sets up only bolt, stops, ends groove ... Deng, the utility model adopts the more convenient processing of this structure.Stop bit 12 is closed in the lock housing 13, and camouflage is good.

As shown in Figure 6: in the band tooth locking bolt 4 toothed portion and no toothed portion being arranged is Different Diameter, and lock pipe 5 recessed herein a section forms stop bit 12, can stop band tooth locking bolt 4 excessively to be withdrawn when unlocking condition.

As shown in Figure 7: have in the gear 1 one section anodontia, band tooth locking bolt 4 and gear 1 meshing (see figure 1) when shutting, band tooth locking bolt 4 is not meshing with gear 1 when unblanking, just when unblanking, band tooth locking bolt 4 is withdrawn to lock to manage under the effect of spring 6 and was with tooth locking bolt 4 and gear 1 not meshing at 5 o'clock, lock core 2 can tooth locking bolt 4 going along with move and rotate, 14 pairs of lock cores 2 of frictional groove play positioning action, key and appurtenance thereof can not rotate yet.

Can be found out that by Fig. 1 and Fig. 7 as long as with the turn clockwise angle of lock core 2 about 2～3 teeth of key, just very little angle just can be opened lock, one-handed performance makes things convenient for.Continuing when shutting has the feel (each frictional groove 3 works) of one-level one-level with the key lock core 2 that turns clockwise during rotation,, shut action and finish when maximum to the feel resistance, can take off key.The utility model also can be made the lock that is rotated counterclockwise, as long as with relevant parts reversing of position.
