The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Described rotary block 1 is L-type, and described rotary block 1 middle part, one end is provided with projection 11, and described rotary block 1 other end is provided with roof door portion 12, and described rotary block 1 is provided with the locking seat 13 corresponding with lock slots 35.
Two end faces of described projection are equipped with the axis hole corresponding with chute 34 14, and described projection is inserted described breach 33, and described jointed shaft 2 inserts axis hole and chute 34, make rotary block 1 and fixed head 3 hinged.In described chute 34, be provided with spring 4, described jointed shaft 2 is located at the side in chute, described spring is located at the opposite side in chute 34, and one end of described spring 4 is connected to the interior side near lock slots 35 of chute 25, and the other end of described spring is connected on jointed shaft 2.Described both ends of the spring is connected to respectively on jointed shaft 2 and chute 34 inwalls, and jointed shaft 2 is extrusion spring together with chute 34 inwalls.
As the utility model technical scheme more specifically, described fixed part 31 is provided with fixing hole 37.Described articulated section 32 is provided with spring mounting hole 36, and spring 4 is installed in chute 34 by this spring mounting hole 36.Described jointed shaft one end is fixedly connected with axis hole, and the jointed shaft other end stretches in chute.The dovetail groove 15 that described roof door portion is provided with, is provided with shockproof glue based 16 on described dovetail groove.
Operating principle of the present utility model:
Fixed head 3 of the present utility model is fixed on the doorframe relative with hinge 6 inner sides by doorframe fixed part 31, and rotary block 1 can be rotated around fixed head 3.
In the time that strengthening theftproof performance, needs (improve knocker in open mode), by rotary block 1 around fixed head 3 towards near door direction rotation, when rotary block 1 rotation is when parallel with door 5, because spring needs to restore to the original state, the lock slots that spring promotes rotary block moves towards locking seat 13 directions of fixed head 3, make the mutual snap close of lock slots on locking seat 13 and the fixed head 3 on rotary block 1, shockproof glue based 16 dog backs of the roof door portion 12 on rotary block 1, therefore cannot open door in people outdoors.
In the time not needing to strengthen theftproof performance, (improve knocker in locking state), the inwardly horizontal rotary block 1 that draws, make the jointed shaft 2 that is fixed on rotary block 1 two ends push the spring in corresponding chute 25, spring is out of shape by compression, thereby the locking seat 13 of rotary block 1 and the lock slots of fixed head 3 are departed from, then centered by fixed head 3, make again rotary block 1 to the direction rotation away from door, make this improvement knocker in open mode.In the time opening the door and do not need to strengthen theftproof performance (open mode), rotary block 1 can rotate freely around fixed head 3, and this rotation can not affect the smooth unlatching of door.Therefore, when the utility model is during in open mode, not dog back of roof door portion, user can directly open door by handle 7.
The utility model only can be applicable to inward opening door, and can adapt to the antitheft of inner door of house and lock, and left and right opening door is all suitable, has met user's demand largelyr.
