Description
Technical field
The utility model relates to a kind of bicycle lock, is a kind of shaft center lock for bicycle.
Background technology
At present, bicycle lock commonly used generally adopts ring lock, U-shape lock, chain lock, such lockset generally comparatively heaviness be not easy to carry, and material the lockset cost of manufacture is relatively high preferably; And the poor lockset of material tends to be opened by violence, there is certain potential safety hazard.For this reason, Granted publication CN201056240Y as the Chinese patent literature publication, May 7 2008 Granted publication day, the utility model name is called " anti-theft shaft lock of bicycle ", it mainly designs and is to consist of auxiliary frame axle sleeve and axostylus axostyle, and in axostylus axostyle, with lock core, the lock core front portion is with the lock core shift fork, the outside suit of axostylus axostyle lock tongue slot frame, have the open-work key in lock core keyhole.This Theft-proof axle-lock is connected on the vehicle crotch by nut.By said structure, make lock and cycle frame be linked as an integral body, make violence unblank to destroy vehicle frame, thus can play certain anti-theft function, but structure design is comparatively complicated, and comparatively inconvenience is installed, and, is further improved for this reason.
Summary of the invention
For overcoming above-mentioned deficiency, the purpose of this utility model is that a kind of shaft center lock for bicycle is provided to this area, makes it solve existing like product structure comparatively complicated, installs and uses the comparatively technical matters of inconvenience.Its objective is and be achieved through the following technical solutions.
A kind of shaft center lock for bicycle, this Shaft center lock is installed on the Chain stay of bicycle rack; Its structural feature is that described Shaft center lock comprises the mechanical code lock that is installed on described Chain stay, and being placed in the interior lock pin by the mechanical code lock linkage telescopic of Chain stay, the rear axle core that the Chain stay of described bicycle rack connects is provided with the lockhole coordinated with described lock pin.By this Shaft center lock being arranged in the Chain stay of bicycle rack, better disguised, and open the Chain stay that will damage bicycle rack by violence, therefore play to a certain extent the purpose that anti-violence is opened.
Two symmetrical Chain stays of described bicycle rack are equipped with described Shaft center lock.Increase the difficulty of unblanking with this, further improve theftproof performance.
Simultaneously, described mechanical code lock replaces with mechanical cylinder lock, also can reach identical purpose.Perhaps, described mechanical code lock or mechanical cylinder lock are connected with the annunciator of bicycle rack, and alert device inside is provided with Vibration alarm device.When violence is opened this Shaft center lock or is collided this bicycle, the alarm and reminding bicycle owner.
The utility model structure is comparatively simple, installs, uses more for convenience, and theftproof performance is good, and more difficult violence is opened, and be suitable as bicycle lock and use, or the structural development of like product.
The accompanying drawing explanation
Fig. 1 is installation site of the present utility model structural representation.
Fig. 2 is mounting structure schematic diagram of the present utility model.
Fig. 3 is the mounting structure schematic diagram after Fig. 2 improves.
Fig. 4 is the installation site structural representation that the utility model adopts mechanical cylinder lock.
In figure, the name of sequence number is called: 1, bicycle rack, 101, Chain stay, 2, mechanical code lock, 3, lock pin, 4, the rear axle core, 5, annunciator, 6, mechanical cylinder lock.
The specific embodiment
Now by reference to the accompanying drawings, the utility model is further described.
As shown in Figure 1 and Figure 2, this shaft center lock for bicycle is installed on the Chain stay 101 of bicycle rack 1, Shaft center lock consists of mechanical code lock 2, lock pin 3, rear axle core 4, annunciator 5, mechanical code lock, lock pin are placed in Chain stay, wherein mechanical code lock is fixed in Chain stay and is connected as a single entity with Chain stay, the mouth interlock of lock pin one end and mechanical code lock, the lockhole that the other end is provided with the rear axle core is pegged graft and is coordinated.Simultaneously, annunciator is connected with mechanical code lock by circuit, and annunciator inside is provided with Vibration alarm device.The concrete using method of this Shaft center lock is: under initial condition, the lockhole that lock pin one end stretches out Chain stay and rear axle core locks, and now the bicycle rear axle core is locked, and can't rotate.When opening mechanical code lock, remove locking by the mouth band pendulum lock pin of mechanical code lock and the lockhole of rear axle core, now the bicycle rear axle core is rotatable; When closing mechanical code lock, then, by the mouth band pendulum lock pin of mechanical code lock and the lockhole locking of rear axle core, realize the locking of bicycle rear axle core.
Except adopting above-mentioned mechanical code lock, this Shaft center lock also can adopt mechanical cylinder lock 6 as shown in Figure 4, and principle of design is similar to mechanical code lock.In order further to improve theftproof performance, as shown in Figure 3, also can above-mentioned shaft center lock for bicycle all be set at two symmetrical Chain stays of bicycle, to increase unlocking difficulty.
