Because the shortcoming of above-mentioned bicycle lockset commonly used, therefore this creator satisfies plentiful and substantial experiences such as the long-pending research of being engaged in this series products for many years, design, manufacturing, actively drop into a large amount of painstaking effort and energy and ground wound, and via after the detection on probation repeatedly, finally success develop a kind of Lock for bicycle of the utility model, make the shortcoming of the above-mentioned lockset commonly used of forgoing.

Main purpose of the present utility model is to provide the Lock for bicycle on a kind of front fork tube that is installed in bicycle, but the mat control handle is the state of deflection or on-deflectable, makes the purpose that reaches the locking bicycle, the various shortcomings of the existing Lock for bicycle commonly used of forgoing.

For reaching above-mentioned purpose, a kind of Lock for bicycle of the utility model is characterized in that: hole outside the front fork tube of bicycle is provided with, in the pipe the solid extension bar of organizing and be provided with endoporus corresponding to outer hole; The place, outer hole of this front fork tube is fixed with a spacer, and spacer is provided with a sleeve corresponding to place, outer hole, and sleeve is interior and be fixed with a lockset; By the locking of above-mentioned lockset, can make the control handle can't deflection and make the bicycle locking.

Be provided with a tapered end in the housing of lockset, the tapered end rear is provided with the block of interlock with it, and block is forced in outer hole of beam tube and the extension bar endoporus, and extension bar is subjected to clip can't rotate and the bicycle that locks control handle.

This connecting element is for a broken end type screw, in case the fastening bit slice is by improper removal.

This lockset is directly to make block start outside housing be forced into hole and extension bar endoporus outside the beam tube in the mode of rotating, directly pushing, push the rotation tapered end, to reach the purpose of the bicycle that locks fast, really.

This shows, the utility model is owing to be that lockset is fixedly set in bicycle inside, but the mat control handle is the state of deflection or on-deflectable, make the purpose that reaches the locking bicycle, conveniently various bicycles are installed, and locking or unlocking operation are fast, really, conveniently, do not influence the profile aesthetic feeling of vehicle body, do not have the problem that produces noise, the various shortcomings of the existing Lock for bicycle of clearly having forgone are so have more progressive.
