Description

The bicycle and tricycle steering lock

The utility model belongs to the stolen equipment of bicycle and tricycle that prevents, particularly a kind of steering lock that is used for locking bicycle three-wheel vehicle foresteerage gear.

At present, bicycle, three-wheel vehicle adopt the ring lock that is installed in the trailing wheel place with the locking trailing wheel mostly, and the transmission of control flywheel can't be ridden.But can mention trailing wheel, utilize front-wheel to roll and carry out, realize stealing or use without permission.Therefore, bicycle, the three-wheel vehicle thing of being stolen often takes place.

The purpose of this utility model is, designs and produces a kind of bicycle and tricycle steering lock, with the horizontal locking of handlebar, reaches and is difficult to carry out the purpose that can't steal.

The technical solution of the utility model is following realization, 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, 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 slide block at the lock core afterbody, be fastened on the lock core with screw, simultaneously parallel pushing down located the locating piece that is positioned between lock core sleeve end and the slide block; Dead bolt is cylindrical, be provided with the dead bolt locating bush, the dead bolt tail end is provided with table top and stage clip, and the dead bolt front end stretches out in the locking rectangle macropore of the locking circular hole of the locking through hole that inserts seat tube simultaneously, vertical tube of front fork and stem, is connected with the pushing pin that dead bolt moves at the dead bolt middle part; The dead bolt middle part is provided with the pin and the dog chart of pick-proof deadlock, and dead bolt locating bush front end is provided with the pick-proof deadlock pin-and-hole perpendicular to the dead bolt axle center; Offer the locking through hole at the corresponding latch bolt position of seat tube, corresponding latch bolt position offers the locking circular hole on the vertical tube of front fork under the horizontal state of front-wheel, and corresponding latch bolt position offers locking rectangle macropore on stem.

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 slide block of dead bolt is stirred dead bolt, makes the locking rectangle macropore of its take advantage of a situation the locking circular hole that withdraws from vertical tube of front fork and stem and unblanks.After unblanking, lock core just rotates a week, extracts key, and pellet shot from a slingshot resets, and has fixed lock core, has controlled lock core and has moved forward, and at this moment handlebar can freely rotate, and this moment, bicycle just can be ridden.

Lock car process is, makes front-wheel deflection certain position earlier, and key inserts lock core, and the anticlockwise direction rotation, and the tongue switching piece contacts with the dead bolt pushing pin, stirs the locking rectangle macropore of the locking circular hole of dead bolt insertion vertical tube of front fork and stem and locks.After the locking, lock core just rotates a week, and tongue switching piece and dead bolt pushing pin are inconsistent, extract key, and pellet shot from a slingshot resets, and has fixed lock core, has controlled moving forward and backward of dead bolt and locks.

Pick-proof deadlock process is because lock body and seat tube are one, to be difficult to during stealing pry open.Might destroy lock core, be fastened on lock core on because of the tongue switching piece this moment, and locating piece is pushed down by the tongue switching piece and be fixed on the lock core sleeve end, so the tongue switching piece is in a single day destroyed, loosening, perhaps dead bolt destroyed, wreck and lose the positioning action of locating piece, the stage clip of dead bolt all will discharge, dead bolt is further moved forward, and the pin of the pick-proof deadlock of this moment is under the promotion of dog chart, just head in the pick-proof deadlock pin-and-hole of dead bolt locating bush front end, dead bolt can not be moved, promptly lock can not be opened, be deadlock state, picking lock is invalid.

The utility model has the advantages that steering lock makes the horizontal locking of front-wheel, can't pretend go-cart and move ahead that even picking lock exists because of the deadlock device is arranged, the thief also can't go smoothly.Simple in structure, be easy to make, easy to operate, assurance bicycle, three-wheel vehicle can not lost.Be applicable to the horizontal steering lock of front-wheel of bicycle, three-wheel vehicle.
