Abstract

The utility model relates to a novel anti-theft bicycle device comprising a rear wheel disc, a rear gear and a lock body, wherein a disc is fastened on the rear wheel disc through a screw fastener; a lock hole is arranged in the disc; a lock body is configured on the outer part of the rear wheel disc, one side of the lock body is provided with a lock cylinder; the lock hole is composed of eight grooves which are arranged in a polar array; the shape of the lock cylinder is matched with the shape of any groove in the lock hole. The novel anti-theft bicycle device has the beneficial effects that the anti-theft function is taken as a basic function of a bicycle, so that the shortcomings that the traditional anti-theft lock of the bicycle can be easily prized up and damaged are overcome fundamentally. As the lock is completely installed in the bicycle, the lock cannot be prized up unless a rear rack of the rear wheel disc of the bicycle is damaged. The disc end face and the lock body form a smaller gap and are installed in the rack, when the lock cylinder is inserted to the rear rack, the lock cannot bed sawed. The novel anti-theft bicycle device has a good anti-theft function, strong practical applicability and lower production cost.

Description

A kind of novel anti-theft bicycle device

Technical field

The utility model relates to the bicycle theft-prevention technology, relates in particular to a kind of novel anti-theft bicycle device.

Background technology

Bicycle is claimed bicycle or bicycle again, and normally the two small-sized land-going machines of taking turns after the people rides car, are power with the foot pedal, are the vehicle of environmental protection.Show that according to investigations the amount of having things stolen in the bicycle year of China is more than 2,000,000 amounts, bicycle theft has also hindered the development of China's bicycle trade when causing very great society loss.In order to prevent bicycle theft, the lockset industry has been done to make great efforts for many years, but is that the high-grade capable lock of U or the spade lever lock of low retaining all do not broken away from the shortcoming that is prone to sled, destructible; The basic reason of bicycle theft is because bicycle itself does not carry out the design of anti-theft feature, and all anti-theft featuries also add nothing but the user; Thereby, for strengthening the intensity that the bicycle theft-prevention function also only is confined to increase lockset, but because the restriction of the volume of lockset, weight, material, cost, the increase of this intensity is limited.Simultaneously, because its function of bicycle lock in the market just protects bicycle not to be removed, rather than the functions of use of protection bicycle, after just making bicycle stolen, this does not influence its normal use, and make car thief be " always enjoying it " to stealing garage.Therefore, to above aspect, need reasonably improve prior art.

The utility model content

To above defective; The utility model provides a kind of novel anti-theft bicycle device; Consider in the lump as an important structure and other functional structure through guarding against theft; So that integral body is provided with on manufacturing, technology, outward appearance and cost, has also damaged the value of service of bicycle in the ruined while of bicycle theft-prevention function simultaneously, thereby made bicycle have best anti-theft feature.

For realizing above-mentioned purpose, the utility model adopts following technical scheme:

A kind of novel anti-theft bicycle device comprises rear trochal disc, backgear, lock body, and is through threaded fasteners that a disk is fastening on the said rear trochal disc, is positioned at disk set inside lockhole; Said rear trochal disc exterior arrangement has a lock body, and this a lock body wherein side is provided with lock core.

For lock body, its characteristic comprises: said lockhole is distributed by eight groove circular array formulas and forms, and the shape size of lock core matches with any groove shapes in the lockhole, has the key mouth on the lock core; Said lock body is fixed on behind the bicycle on the vehicle frame through threaded fasteners.

The beneficial effect of the described novel anti-theft bicycle device of the utility model is: through transplanting the principle of general lockset and combining with bicycle structure is ingenious; Apply in the design of bicycle theft-prevention, promptly the main position of this structure is the gear on after poppet, rear axle and the rear axle of bicycle; Be embodied in:

(1) when bicycle structure is made, the basic function of anti-theft feature as bicycle taken in, fundamentally solved the shortcoming that the standard bicycle anti-theft column lock is prone to sled, destructible;

(2) because this lock is inner at bicycle fully,, otherwise can not be prized only if the rear trochal disc after poppet partial destruction of bicycle;

(3) since the disk end face with the lock body part gap is less and inboard at support, when lock core insertion after poppet, can't be sawed especially;

(4) adopt gear coordinated type bicycle theft-prevention lock construction to possess good anti-theft feature, have very strong practicality, have lower productive costs.

Description of drawings

According to accompanying drawing the utility model is done further explain below.

Fig. 1 is the decomposition texture scheme drawing of the said novel anti-theft bicycle device of the utility model embodiment;

Fig. 2 is the integral structure scheme drawing of the said novel anti-theft bicycle device of the utility model embodiment.

Among the figure:

1, rear trochal disc; 2, backgear; 3, disk; 4, lockhole; 5, lock body; 6, lock core; 7, key mouth.

The specific embodiment

Shown in Fig. 1-2; The described novel anti-theft bicycle device of the utility model embodiment; Comprise rear trochal disc 1, backgear 2, lock body 5; Rear trochal disc 1 is arranged at bicycle rear circle center position and is structure as a whole with rim, thereby as long as the locking rear trochal disc has promptly locked rear rim and trailing wheel then can't rotate; A disk 3 is fastening on the said rear trochal disc 1 through threaded fasteners, simultaneously, be positioned at disk 3 set inside lockholes 4 so that the lock car is convenient, this lockhole 4 is distributed by eight groove circular array formulas and forms; Said rear trochal disc 1 exterior arrangement has a lock body 5; This lock body 5 a wherein side is provided with the lock core 6 of key mouth 7 and any groove shapes in this lock core 6 shapes and the lockhole 4 matches; So no matter which groove this lock core 6 inserts in, all can lock be lived; Simultaneously, on the vehicle frame, for strengthening anti-theft effect, right back support adopts solid steel as material this lock body 5 can be fixed in bicycle with threaded fasteners when producing after.

The described novel anti-theft bicycle device of above the utility model embodiment; This bicycle is the same with ordinary bicycle when cruising, and when stretcher drove the chain rotation, chain drove backgear 2 and rotates; Backgear 2 drives rear trochal disc 1 again and rotates; And rear trochal disc 1 is connected as a single entity with the bicycle rear circle, has so just driven the rear rim rotation, has realized riding of bicycle; Can drive when backgear clockwise rotates that rear rim rotates and can not drive rear rim when rotating counterclockwise and rotate.Its principle comprises:

1. when the lock car, step on stretcher, the lockhole 4 on lock core 6 alignment disk 3, only needing then to insert key is lockable, has so just locked trailing wheel through the lock on the rear trochal disc 1; Under lock-out state; The bicycle rear circle, can not be ridden away so can't push away away owing to fixed by after poppet through lock simultaneously; In sum, this bicycle theft-prevention is locked in and has realized under the lock-out state being pushed away away the good theftproof performance that can not be ridden away again;

2. when unblanking, only need to open lock and get final product with key, because of considering the maintenance problem of anti-theft column lock part,, keep in repair under then can directly dismantling lock body 5 parts as if locking damage because lock body 5 is to be connected through vehicle frame behind threaded fasteners and the bicycle.

Above embodiment is the more preferably specific embodiment a kind of of the utility model, and common variation that those skilled in the art carry out in present technique scheme scope and replacement should be included in the protection domain of the utility model.
