The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment 1, in conjunction with Fig. 1 to Fig. 7, a kind of knocker, comprise rotary block 1, jointed shaft 3 and fixed head 2, described rotary block 1 is L-type, and rotary block 1 one end is provided with breach 11, the top of described breach 11, the axis hole 13 that bottom is equipped with concentric, breach 11 is provided with locking seat 12, and described rotary block 1 other end is provided with roof door portion 14.
Described fixed head 2 comprises doorframe fixed part 21 and articulated section 24, and two end faces of described articulated section 24 are equipped with the chute corresponding with axis hole 13 25, and 24 bottoms, described articulated section are provided with the lock slots 26 corresponding with locking seat 12.Described breach 11 is inserted in described articulated section 24, and described jointed shaft 3 inserts axis hole 13 and chute 25, makes rotary block 1 and fixed head 2 hinged.
In described chute 25, be provided with spring 4, one end of described spring 4 is connected to the interior side near lock slots 26 of chute 25, and the other end of described spring is connected on jointed shaft 3.Described both ends of the spring be connected to respectively on jointed shaft 3 outer walls and chute 25 inwalls on, jointed shaft 3 is extrusion spring 4 together with chute 25 inwalls.
As the utility model technical scheme more specifically, described doorframe fixed part 22 is provided with fixing hole 22.As shown in Figure 5,24 tops, described articulated section are provided with spring mounting hole 15, and spring 4 is installed in chute 25 by this spring mounting hole.Described jointed shaft 3 one end are fixed in axis hole 13, and jointed shaft 3 other ends stretch in chute 25, and are connected on one end of spring.The dovetail groove 16 that described roof door portion 14 is provided with, is provided with shockproof glue based 5 on described dovetail groove.
Operating principle of the present utility model:
In conjunction with Fig. 1 to Fig. 7, described fixed head 2 is fixed on the doorframe relative with hinge 97 inner sides by doorframe fixed part 22, and rotary block 1 can be rotated around fixed head 2.
In the time that needs are strengthened theftproof performance (knocker is in open mode), by rotary block 1 around fixed head 2 towards near door direction rotation, when rotary block 1 rotation is when parallel with door 6, because spring needs to restore to the original state, the locking seat 12 that spring promotes rotary block moves towards lock slots 26 directions of fixed head, make the mutual snap close of lock slots 26 on locking seat 12 and the fixed head 2 on rotary block 1, shockproof glue based 5 dog backs of the roof door portion 14 on rotary block 1, therefore cannot open door in people outdoors.
In the time not needing to strengthen theftproof performance (knocker is in locking state), the inwardly horizontal rotary block 1 that draws, make the jointed shaft 3 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 12 of rotary block 1 and the lock slots 26 of fixed head 2 are departed from, then centered by fixed head 2, make again rotary block 1 to the direction rotation away from door, make this 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 2, 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 8.
Embodiment 2, in conjunction with Fig. 8 and Fig. 9, embodiment 2 is similar to the embodiment of embodiment 1, unique distinctive points is: described spring mounting hole 15 is located at the bottom of the articulated section 24 of fixed head 2, the utility model is by bottom, the articulated section mounting spring of fixed head, and easy for installation, efficiency is high.
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.
