Background technology
At present, common smart card door lock includes pair lock of opening with smart card and the main lock of opening with mechanical key on the market.The mode that people usually adopt smart card to open secondary lock is opened the door, and just adopts mechanical key to open main lock during special circumstances such as losing, forget Password at smart card.Main in the ordinary course of things lock does not need to use, and is if main lock directly is exposed at the surface of lock, easily by contamination by dust, simultaneously not attractive in appearance yet.Existing smart card door lock generally also has tapered end cover that main locking closure is lived, but often needs to tick tapered end cover by special tool, uses inconvenient.
Summary of the invention
The purpose of this utility model provides a kind of tapered end cover bayonet unit that is used for the main lock of intelligent door lock, and tapered end cover has covered keyhole and tapered end, and is both dustproof, attractive in appearance again, finger one is pressed gently, can take out tapered end cover, does not need by any instrument, simple in structure, easy to use, cost of production is low.
In order to achieve the above object, the technical solution of the utility model is as follows:
A kind of tapered end cover bayonet unit comprises tapered end cover 1, snap pin assembly 3, snap pin back-moving spring 4, control button 5, control button back-moving spring 6; The centre of locking face 2 has groove, 21 bottoms of locking face 2 are provided with a ring-type through hole 7, control button 5 lower end shapes match with hole 7, and can move freely, radially match with groove 22 in the outer ring of control button 5, control button 5 is provided with an aperture 8, and control button back-moving spring 6 places hole 8, and two ends offset with 21 bottoms of 8 bottoms, hole and locking face 2 respectively; Tapered end cover 1 places in the groove 23 of locking face 2, radially matches with groove 23 in the outer ring, and tapered end cover 1 center is provided with a through hole 9; The side of tapered end cover 1 is provided with symmetrical through hole 10, and snap pin assembly 3 places hole 10, and snap pin back-moving spring 4 is enclosed within on the snap pin assembly 3, and locking face 2 is provided with through hole 11 with respect to the direction in the hole 10 of tapered end cover 1.
Described snap pin assembly 3 comprises snap pin 31 and setscrew nut 32, and the two ends of snap pin back-moving spring 4 offset with the inboard of setscrew nut 32 and tapered end cover 1 respectively.
The side opening 10 of described tapered end cover 1 is a shoulder hole.
Described control button 5 upper ends are approximately convex shape, and hole 9 shapes of tapered end cover 1 match with it, and the upper end of control button 5 is provided with lead angle.
Owing to adopted said structure, utilize snap pin assembly 3 to insert and do not insert locking face 2, make to engage between locking face 2 and the tapered end cover 1 and separate, thereby realize the chucking of tapered end cover 1 and the operation that gets loose.
