Abstract
The utility model relates to a bicycle lock. The theft-proof lock for bicycles is characterized in that lock bodies and a lock core mechanism are symmetrically arranged on a fork frame which is parallel to a bicycle wheel; a lock rod and a restoring spring of the lock rod are respectively arranged on the two lock bodies; the symmetrical lock rods are respectively perpendicular to the bicycle wheel; when the bicycle is locked, the front ends of the symmetrical lock rods are in a cross connection position; the rear end of each of the lock rod is provided with a shoulder stage which isadhered to the lock bodies; the front end of the corresponding lock rod is also provided with an abdication retainer ring. When the utility model with the structural feature characteristics is reliably installed, anti-prizing performance and anti-smash performance can be ensured to achieve an anti-theft purpose.
Description
The utility model is about a kind of bicycle lock.
Lockset that existing relevant bicycle is supporting and anti-theft column lock are seen in a lot of of report, can be divided into two classes by mounting means on the structure, and a class is movable lockset, hang onboard locking temporarily; Another kind of lockset is fixed on the vehicle body, this kind version adopts the lock ring structure mostly, with the utility model more approaching be a kind of two tapered ends that have, but have only a lock core and the locking bar that passes the bicycle spoke, the maximum deficiency of this kind version tapered end is that locking bar shrinks inconvenience, in addition unidirectional bang damages tapered end lock core mechanism and damaging property is unblanked, the antitheft purpose of out of reach easily.
The purpose of this utility model be to overcome the deficiency that above-mentioned prior art exists and provide a kind of compact conformation rationally, device rationally, anti-theft lock for bicycle that theftproof performance is good.
These anti-theft lock for bicycle characteristics are to be arranged with lock body and lock core mechanism thereof on the crotch parallel with cycle wheel, be equipped with locking bar and retracing spring thereof on two lock bodies, the locking bar of symmetry is all vertical with bicycle quick, when sealed, the locking bar front end of symmetry is in the intersection engage position, the locking bar rear end is provided with the shoulder rank and lock body is fitted, and corresponding locking bar front end also is provided with the back-up ring of giving up the throne.
The further setting of the utility model is that the bicycle quick crotch cross-sectional plane of fixed installation lock body is square.
The utility model of said structure characteristics is prevented pounding as long as installation reliably then can guarantee pick-proof, reach antitheft purpose, in addition the enthusiasm that can give full play to cycle manufacturer merchant, lock manufacturer and user three parts is set further, special square crotch also provides a good opportunity that dominates the market for bicycle manufacturer.
Further illustrate the utility model below in conjunction with description of drawings, provide embodiment simultaneously.
Fig. 1 is the utility model embodiment lock body part cutaway view.
Fig. 2 is the utility model embodiment integral installation structural representation.
Fig. 3 is the local amplification view of Fig. 2.
