Abstract
The utility model relates to an anti-theft device arranged on a bicycle, comprising a spring lock head arranged in the shoulder pipe of a bicycle front fork, a drive bolt arranged in the vertical pipe of the bicycle front fork, a drive nut, and a movable cylindrical pin. The utility model is characterized in that all components are hidden in the shoulder pipe of the bicycle front fork and the pipe cavity of the vertical pipe of the bicycle front fork, which can effectively protect the bicycle lock members from being prized and sawn.
Description
The utility model relates to a kind of anti-theft device that is contained on the bicycle.
Stolen for preventing bicycle, bicycle lock must be installed.Common bicycle lock all is installed in external surface, because of its member exposes, is prized, is sawed easily.
Prized for solving lock, by the saw problem, best bet is that the lock member is stashed.A kind of pipe shoulder formula bicycle lock that Jinyun bicycle Lock Factory produces, its tapered end is contained in the bicycle front fork shoulder pipe, and certain disguise is arranged, but it is as main member---the lock pin of locking, and still passes front cross-shoulder tube and part exposes, and existing may by sawed-off.Simultaneously it also needs to install one and is with the member of pin-and-hole cooperate with lock pin bicycle front tube outside, and the original outward appearance of bicycle is had certain influence.
The purpose of this utility model is that a kind of improved built-in bicycle theft-prevention locking device will be provided, it can prevent effectively the bicycle lock member prized, by the saw problem.
The purpose of this utility model is achieved in that the side shoulder pipe pore along bicycle front fork, the vertical tube of front fork that intersects is with it bored a through hole, one end of one drive screw is connected with the lock core of cylinder lock head in being contained in front cross-shoulder tube, and the other end passes through hole and the transmission nut that is contained in the vertical tube of front fork cooperates.Movable pin and spring are equipped with in the upper end of transmission nut, are drilled with pin-and-hole at the standpipe wall place of aiming at pin.Key, can nut be moved, thereby make pin pass the otch that pin-and-hole heads into the steel bowl that is fixed on bicycle front tube, bicycle front fork is stuck in a certain angle, thus make bicycle front-wheel and vehicle body at an angle and in stays.
The utility model all is installed in the front cross-shoulder tube, standpipe of bicycle because of its member, thus can prevent effectively the lock member prized, by according to problem, and do not influence the original outward appearance of bicycle.
The concrete structure of utility model is provided by following embodiment and accompanying drawing:
Accompanying drawing is the cross-sectional schematic according to the built-in bicycle theft-prevention locking device that the utility model proposes.
This device comprises that being contained in the bicycle front fork shoulder manages the cylinder lock head (2) in (1) and be contained in vertical tube of front fork (9) interior drive screw (4), transmission nut (5), there are a movable pin (6) and spring (7) in the transmission nut upper end, one end of drive screw cooperates with transmission nut, and the other end passes through hole and connects (also can be connected as a single entity with lock core (3)) with the lock core (3) of cylinder lock.Lock is unlocked among the figure.
When with key rotation lock core (3), drive screw is along with rotation, and pin (6) is then along with transmission nut moves along the direction of arrow, so that head into the otch of steel bowl (11), bicycle front fork promptly is stuck and can't rotates, thereby the bicycle front-wheel is stuck in a certain angle.Steel bowl (11) is fixed in the bicycle front tube (10); Spring (7) plays trace adjusting displacement effect automatically; The effect of nut bracket (8) is to prevent the transmission nut swing.
Claims (3)
1, is contained in anti-theft lock device on the bicycle, this device has a cylinder lock head (2) that is contained in the bicycle front fork shoulder pipe (1), it is characterized in that in the tube chamber of bicycle front fork standpipe (9) drive screw (4) and transmission nut (5) being arranged, a movable pin (6) and spring (7) are arranged on the transmission nut (5).
2, device according to claim 1 is characterized in that drive screw (4) connects mutually with the lock core (3) of cylinder lock head (2) or one each other.
