Abstract
The utility model provides an anti-theft lock of the bicycle used for locking the front fork 10 of the bicycle and arranged in a beam, in particular arranged in a lower inclined beam 1. A lock core 4 is exposed from the side surface of the lower inclined beam 1. A transmission round plate 3 is provided with a spiral slot and a center hole with a small convex table. The lock core 4 is provided with a small slot and the right end surface of a lock tongue 7 is provided with a pin hole and a slot. A pin 5 connects the lock tongue 7 with the transmission round plate 3. The lock tongue 7 is sheathed with a spring 6. The lock tongue 7, the transmission round plate 3, the pin 5, the spring 6 and the lock core 4 are arranged in a lock body 2 and also the left end of the spring 6 is sealed by a thin plate 8. To the bicycle provided with the anti-theft lock of the bicycle head, the only way of destroying the lock is destroying the bicycle and the lock together.
Description
Technical field:
The utility model relates to a kind of anti-theft lock for bicycle that is installed in the beam, particularly is installed in the lower inclined beam with bicycle front fork sleeve bonded assembly triangle thick stick, is used to lock the anti-theft column lock of bicycle front fork.
Background technology:
The social at present anti-theft lock for bicycle of going up use all is the outside that lock is installed in bicycle, is used to lock the wheel of bicycle.Lock is exposed to the outside of bicycle, and the thief uses tool used in crime such as clipper to be easy to lock destruction is stolen bicycle.The theftproof performance of common lock is poor thus, and common lock gets rusty easily, and is not durable inconvenient operation.The domestic in recent years people of having has designed the lock that is installed in the car body voluntarily, as " hidden-in-handlebar antithief lock for bike " (application number 89211663.3) etc., because complex structure manufacturing and installation difficulty not only, and can not regulate the height of handlebar.
Summary of the invention:
In order to overcome the shortcoming that present bicycle lock exists, the utility model provides a kind of bicycle headstock anti-theft column lock, and this is locked, and not only theftproof performance is good, and durable, attractive in appearance, simple to operate.
The utility model is by the following technical solutions: the bicycle headstock anti-theft column lock is installed in the beam of bicycle, particularly is installed in the lower inclined beam of bicycle, be used to lock the front fork of bicycle.Bore a hole in the left side of lower inclined beam, lock core is exposed.A lock core hole is arranged, a dead bolt hole and an elongated slot on the lock body.The right side processing aperture of lock body is used to install the pellet shot from a slingshot and the little spring of lock.The right-hand member of dead bolt has a pin hole and a sulculus.A plug helix and the centre hole that small boss is arranged are arranged on the transmission disk.A sulculus is arranged on the lock core, and sulculus cooperates with the small boss of transmission disk.Pin links up dead bolt and transmission disk, and spring is set on the dead bolt, with dead bolt, and the transmission disk, spring, lock core is put into lock body, and has the thin slice of centre hole to seal spring with one.Under the natural left bevelled state of bicycle headstock, clockwise rotate lock core, transmission disk and lock core rotate together, and in the time of the dead bolt compression spring, the left end of dead bolt reaches in the hole of front fork, and front fork can not be rotated, and just reaches the purpose of lock car.
Description of drawings:
Fig. 1 is structural representation of the present utility model a---front view.
Fig. 2 is structural representation of the present utility model a---birds-eye view.
The specific embodiment:
Below in conjunction with drawings and Examples the utility model is further specified.
Among the figure: 1-lower inclined beam, 2-lock body, 3-transmission disk, 4-lock core, 5-pin, 6-spring, 7-dead bolt, 8-thin slice, 9-front fork sleeve, 10-front fork.
Respectively bore the hole of and lower inclined beam 1 concentric on bicycle front fork 10 in the drawings and the front fork sleeve 9, bore a hole, lock core 4 is exposed from the hole in the left side of lower inclined beam 1.Lock body 2 is a radius and the much the same cylinder of lower inclined beam 1 internal diameter.On lock body 2, bore a lock core hole with the lock body intersect vertical axis, one of lock body 2 left ends processing and lock body 2 concentrics and vertical with lock core hole with the lock core 4 vertical dead bolt holes that communicate with one and with the crossing elongated slot in lock body 2 left sides.The right side processing aperture of lock body 2 is used to install the pellet shot from a slingshot and the little spring of lock.Dead bolt 7 is small cylinders, and at the pin hole of right-hand member processing and a short groove vertical with pin hole of dead bolt 7, transmission disk 3 is installed in the groove of lock body 2.Sulculus vertical of processing on lock core 4 with key.Plug helix and the centre hole that small boss is arranged that a 360 deg is arranged on the transmission disk 3.Pin 5 snaps in the plug helix of the pin hole of dead bolt 7 and transmission disk 3, dead bolt 7 and transmission disk 3 are linked up, dead bolt 7 and transmission disk 3 are put into lock body 2, when the groove on the lock core 4 cooperates with the small boss of transmission disk 3, lock core 4 is put into lock core hole.Spring 6 is set on the dead bolt, and seals the left end of spring with a thin slice 8 that centre hole arranged, and in the right side of lock body the pellet shot from a slingshot and the little spring of locking is installed.Under the oblique left naturally state of bicycle headstock, with key rotation lock core 4, transmission disk 3 and lock core 4 rotate together, thereby pin 5 is along plug helix the moving of drive dead bolt 7 of moving.Under the natural left bevelled state of bicycle headstock, when locking, clockwise rotate, in the time of dead bolt 7 compression springs, the left end of dead bolt 7 reaches in the hole of front fork 10, and front fork 10 can not be rotated, and just reaches the purpose of lock car.When unblanking, rotate counterclockwise lock core 4 with key, dead bolt 7 withdrawals, front fork 10 is free to rotate.
