Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in figures 1-4, the utility model describes a kind of direct plugging-in door lock with anti-lock core reverse function, comprises motor base 1, change gear box 2, oblique top gear 3, tooth bar 4 and lock core mechanism 5; Concrete, change gear box 2 is fixed on motor base 1, and oblique top gear 3 is installed on the sidewall of change gear box 2 simultaneously, be that one end is meshed with oblique top gear 3, and the other end is connected with lock core mechanism 5, to form transmission mechanism as tooth bar 4;
Preferably, above-mentioned change gear box 2 is connected with the axle center of oblique top gear 3 by axis of rotation (not marking in the drawings), drives oblique top gear 3 to rotate with this.
Wherein, oblique top gear 3 is fixed with the gear inclined arm of force 31 away from the side of change gear box 2, and the side of tooth bar 4 is fixed with the oblique block 41 of tooth bar, the oblique block 41 of this tooth bar is concave structure and comprises positive stop 411 and backstop 412;
Preferably, in order to better and the oblique block 41 of tooth bar are fitted, so the local of one end of the close oblique block 41 of tooth bar is ramp structure 311 on the gear inclined arm of force 31, and its slope is all identical with the slope of positive stop 411 and backstop 412.
Meanwhile, one end of the gear inclined arm of force 31 is fixed on oblique top gear 3, and the other end is inserted in the concave structure of the oblique block 41 of tooth bar, namely between positive stop 411 and backstop 412; Preferably, the top of above-mentioned positive stop 411 is provided with limited block 4111, and this limited block 4111 can the movement of limiting gear oblique force arm 31 further, avoids it to skid off positive stop 411.
In addition, lock core mechanism 5 is provided with several lock cores 51; Preferably, the quantity of this lock core 51 is 2, and lays respectively at two ends of lock core mechanism 5, and the structure of this kind of symmetrical expression can increase the stability of lock core mechanism 5.
Preferably, simplifying most to reach structural, tooth bar 4 being arranged at the below of oblique top gear 3, oblique for tooth bar block 41 is arranged at immediately below the gear inclined arm of force 31 simultaneously.
In the utility model, the operating principle of direct plugging-in door lock is: first drive oblique top gear 3 to rotate by change gear box 2, carry-over bar 4 is with to do rectilinear motion by oblique top gear 3 again, and then by tooth bar 4 pushing lock cylinder mechanism 5, lock core 51 is stretched out, until the gear inclined arm of force 31 and positive stop 411 are removed completely, so far complete operation of locking a door;
Now, if any external force by lock core 51 forced back, then oblique top gear 3 is driven to do return motion by tooth bar 4, when the gear inclined arm of force 31 contacts with backstop 412, due to the barrier effect of backstop 412, oblique top gear 3 cannot be reversed further, so just can prevent the retraction movement of lock core 51, reach the effect preventing lock core 51 from reversing.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
