The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done to detailed introduction: as shown in accompanying drawing 1,3,5, the utility model comprises latch 1, square rod axle 2, axle sleeve 3, described square rod axle 2 is placed in axle sleeve 3, axle sleeve 3 is nested with square rod shaft gear 8, square rod shaft gear 8 is connected with one end of the first extension spring 9, and the other end of the first extension spring 9 is fixed in lock housing 7; In described square rod axle 2, offer pin hole 21, offer axle sleeve pin hole 31 in axle sleeve 3, when this pin hole 21 and 31 contraposition of axle sleeve pin hole, latch 1 inserts in this pin hole 21 and axle sleeve pin hole 31; One end of described latch 1 contacts with damper push rod 4, and this damper push rod 4 is connected with lever spring 6, and this lever spring 6 contacts with the elastic force mouth 51 of opening key 5; Described damper push rod 4 is connected with one end of the second extension spring 10, and the other end of this second extension spring 10 is fixed in lock housing 7.
As shown in accompanying drawing 4,6,7,8, in described square rod axle 2, be inserted with a rectangular bar 11 or be inserted with an indoor square rod 13 and an outdoor square rod 12; Described outdoor square rod 12 is directly inserted in square rod axle 2, and described indoor square rod 13 is provided with two forks 131, by these two forks 131, indoor square rod 13 is inserted on the axle sleeve double flute 32 of axle sleeve 3.
Clutch operating principle of the present utility model is:
When opening key 5, up move after stressed, elastic force mouth 51 has promoted 6 rotations of lever spring, and damper push rod 4 is moved on stressed, and when pin hole 21 is during with 31 contraposition of axle sleeve pin hole, latch 1 moves under the thrust of damper push rod 4, has eaten square rod axle 2 and axle sleeve 3 makes it synchronous.When rotating square rod axle 2, axle sleeve 3, square rod shaft gear 8 are also rotated thereupon.As shown in Figure 1.When rotating the power disappearance of square rod axle 2, the first extension spring 9 pulls original position by square rod axle 2, axle sleeve 3, square rod shaft gear 8; When opening key 5 when no longer stressed, the second extension spring 10 retracts original position by damper push rod 4.
When pin hole 21 is during with the 31 not contraposition of axle sleeve pin hole, to open key 5 and up move after stressed, elastic force mouth 51 has promoted 6 rotations of lever spring, because pin hole 21 and the 31 not contrapositions of axle sleeve pin hole, latch 1 cannot enter position.Lever spring 6 is keeping a kind of torsion to damper push rod 4 all the time, as Fig. 2.But when rotation square rod axle 2, while making pin hole 21 with 31 contraposition of axle sleeve pin hole, damper push rod 4, under the twisting force of lever spring 6, pushes square rod axle 2 and axle sleeve 3 by latch 1, completes clutch state.
Clutch advantage of the present utility model is:
While 1, unblanking, when square rod axle 2 is synchronizeed with axle sleeve 3 positions, the elasticity by damper push rod 4 is advanced to optimum position by latch 1 all the time, thereby has ensured the application life of door lock.
2, door lock is in use due to after time length, the various factors such as stay of handle causes dead bolt to eject end while putting in place, while making square rod axle 2 asynchronous with axle sleeve 3, by the elastic reaction of damper push rod 4, do not make the rigid top of latch 1 hinder, now, as long as outside door handle promotes damper push rod 4 latch 1 is inserted to square rod axle 2 by carrying or be depressed into after certain angle elastic force by lever spring 6 on square rod, now still can as usual unblank.
3, this clutch forms square rod axle and axle sleeve have two kinds of functions: 1, adopting a rectangular bar 11 to become indoor and outdoor all needs to open the lock with the key.2, adopt inside and outside two kinds of square rods: outdoor square rod 12 is directly inserted in square rod axle 2, idle running at ordinary times, must will be opened after key 5 pushes up above and just can be unblanked by lock core jacking block with key.3, indoor square rod 13 131 is inserted on the axle sleeve double flute 32 of axle sleeve 3 with two forks, thereby can press at any time handle and open the door indoor.
The utility model is not limited to above-mentioned embodiment; no matter do any variation in its shape or material formation; every employing structure design provided by the utility model, is all a kind of distortion of the present utility model, all should think within the utility model protection domain.
