Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the present invention is further described.Hereinafter implement
Example is only used for clearly illustrating technical scheme, and can not limit the protection model of the present invention with this
Enclose.
As shown in figures 1-4, this invention describes a kind of direct plugging-in door lock with anti-lock core reverse function, including
Motor base 1, change gear box 2, oblique top gear 3, tooth bar 4 and lock core mechanism 5；Concrete, speed 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, extremely
It is then that one end is meshed with oblique top gear 3 in tooth bar 4, and the other end is connected with lock core mechanism 5, in order to formed
Drive mechanism；
Preferably, above-mentioned change gear box 2 is by rotary shaft (marking the most in the drawings) and oblique top gear 3
Axle center is connected, and drives oblique top gear 3 to rotate with this.
Wherein, on oblique top gear 3, the side away from change gear box 2 is fixed with the gear inclined arm of force 31, and
The side of tooth bar 4 is fixed with the oblique block of tooth bar 41, and the oblique block of this tooth bar 41 is for concave structure and includes positive stop
411 and backstop 412；
Preferably, in order to preferably block 41 oblique with tooth bar is fitted, thus close on the gear inclined arm of force 31
The local of one end of the oblique block of tooth bar 41 is ramp structure 311, and its slope and positive stop 411 and backstop
The slope of block 412 is the most identical.
Meanwhile, one end of the gear inclined arm of force 31 is fixed on oblique top gear 3, and the other end to be inserted into tooth bar oblique
In the concave structure of block 41, i.e. between positive stop 411 and backstop 412；Preferably, before above-mentioned
The top of block 411 is provided with limited block 4111, and this limited block 4111 can limiting gear oblique force arm further
The movement of 31, it is to avoid it skids off positive stop 411.
Additionally, lock core mechanism 5 is provided with several lock cores 51；Preferably, the quantity of this lock core 51 is 2,
And laying respectively at two ends of lock core mechanism 5, the structure of this kind of symmetrical expression can increase the steady of lock core mechanism 5
Qualitative.
Preferably, in order to reach the simplification in structure, tooth bar 4 is arranged at the lower section of oblique top gear 3, with
Time oblique for tooth bar block 41 is arranged at the underface of the gear inclined arm of force 31.
In the present invention, the operation principle of direct plugging-in door lock is: first driven oblique top gear 3 to do by change gear box 2
Rotary motion, then moved along a straight line by oblique top gear 3 band carry-over bar 4, and then by tooth bar 4 pushing lock cylinder mechanism
5 so that lock core 51 stretches out, until the gear inclined arm of force 31 releases completely with positive stop 411, so far complete lock
Door operation；
Now, if any external force by lock core 51 forced back, then oblique top gear 3 is driven to do reversion fortune by tooth bar 4
Dynamic, when the gear inclined arm of force 31 contacts with backstop 412, make due to the barrier effect of backstop 412
Oblique top gear 3 cannot invert further, the most just can prevent the retraction movement of lock core 51, reaches to prevent lock core
The effect of 51 reversions.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all in the present invention
Spirit and principle within, any modification, equivalent substitution and improvement etc. made, should be included in the present invention's
Within protection domain.
