The purpose of this utility model is: design and produce a kind of bicycle and tricycle steering lock, with the horizontal locking of handlebar, reach and be difficult to carry out the purpose that can't steal.

The technical solution of the utility model is achieved like this, and a kind of bicycle and tricycle steering lock comprises lock body, lock core, dead bolt, and its lock body is arranged on the seat tube of bicycle and tricycle, constitutes one with seat tube; The lock core front is towards the side of seat tube, and lock core is provided with key hole, lock core sleeve, between lock core and lock core sleeve, be provided with the pellet shot from a slingshot hole of corresponding key, be provided with pellet shot from a slingshot, pellet shot from a slingshot spring, pellet shot from a slingshot lead sealing in the pellet shot from a slingshot hole, vertically place lock core dowel at the lock core afterbody, lock core is provided with the 9-1 double wedge; Dead bolt is cylindrical, is provided with the recessed tooth of dead bolt 4-1, and the dead bolt tail end is provided with the dead bolt locating dowel pin, and the dead bolt front end stretches out in the locking rectangular opening of the locking circular hole of the locking through hole that inserts seat tube simultaneously, vertical tube of front fork and stem.

Described dead bolt middle part is provided with the recessed tooth of dead bolt and is connected extended lock car of rotational lock core dead bolt or unlatching with lock core 9-1 double wedge.

The corresponding latch bolt position of described seat tube offers the locking through hole, and corresponding dead bolts are put and offered the locking circular hole on the vertical tube of front fork under the horizontal state of front-wheel, and corresponding latch bolt position offers rectangular opening on stem.

The utility model has the advantages that: steering lock uses the horizontal locking of front-wheel, and the thief can't pretend go-cart and move ahead, even prize a lock, because of lock body is that an integral body can't be gone smoothly.Be applicable to the front-wheel steering lock of bicycle, three-wheel vehicle.

Using method of the present utility model: the process of unblanking is, when key being inserted in the key hole of lock core clickwise, the double wedge of lock core 9 inserts the recessed tooth of dead bolt, continues rotation, stirring dead bolt moves backward, when treating that lock core rotates a circle, lock core 9-1 double wedge just vertically injects in the recessed tooth of dead bolt 4-1, meanwhile, the pellet shot from a slingshot contraposition, transfer to key, move after pellet shot from a slingshot 7 resets and behind the protruding 9-1 control of the lock core dead bolt, lock is opened.

Lock car process is to make front-wheel deflection certain position earlier, key insertion lock core hole, and the anticlockwise direction rotation, the lock core double wedge is stirred the dead bolt reach, when rotating a circle, lock core double wedge 9-1 stirs the dead bolt reach, meanwhile, dead bolt location lock 5 just is inserted in dead bolt 4-2 rear end platform valency, the reach of control dead bolt, pellet shot from a slingshot contraposition, transfer to key, pellet shot from a slingshot 7 reset and lock core double wedge 9-1 control dead bolt after move i.e. locking.

The utility model has the advantages that: steering lock makes the horizontal locking of front-wheel, can't pretend go-cart and move ahead.Simple in structure, be easy to make, easy to operate, assurance bicycle, three-wheel vehicle can not lost.Being applicable to that the front-wheel of bicycle, three-wheel vehicle is horizontal locks with steering lock.
