Abstract

The utility model relates to a new theftproof bicycle, belonging to the vehicle field, which is characterized in that: a handlebar which is free and convenient in assembly and disassembly and carrying, and a corresponding positioning and locking mechanism are provided; the handlebar can be an integrative structure or a left and right half-handlebar structure, and is connected with a front fork connector (3) through a connecting tube (2); the connection of the front fork connector (3) and the front fork (14) is the same with the general bicycle. The utility model has the advantages that: no matter in temporary storage of outgoing general use or longtime disuse, more particularly the storage at night, the bicycle handlebar can be conveniently disassembled and carried; the bicycle without a handlebar can not be ridden, even difficult for pushing forward; when the bicycle without a handlebar is stolen, the thief has nothing to do because of the noticeable shape and difficult assembly. The utility model also has the advantages of simple structure, easy operating, no change of the basic structure and performance of the bicycle, extremely simple and convenient assembly and disassembly and carrying of the handlebar.

Description

The novel anti-theft bicycle

Technical field: the utility model belongs to the vehicle, relates to a kind of novel anti-theft bicycle.

Background technology: walking-replacing tool---bicycle, its antitheft prevailing method is to install outer lock additional, but its antitheft effect is limited, the one, lock is opened easily, destroyed, and the one, can not unblank easily and car load is smuggled; Other anti-theft measures have: go into storehouse or be placed in the special-purpose anti-joyride device, install second road lock additional, not only inconvenient, and majority do not satisfy the requirements, after while can only solve and go home, long period antitheft during, and the antitheft never measure preferably during temporarily depositing when normally using outside without car.

Summary of the invention:

The technical matters that solves: employing is the handle bar structure of conveniently assemble and disassemble at any time, solves the bicycle theft-prevention problem, and antitheft during temporarily depositing when promptly can be used for going out normally to use also is applicable to the long period without car, particularly night antitheft problem.

Technical scheme:

The novel anti-theft bicycle has the basic structure of ordinary bicycle, it is characterized in that: have at any time conveniently assemble and disassemble and the bicycle handle bar that carries and location and lockout mechanism accordingly.

Beneficial effect: no matter be temporarily depositing when going out normally to use, or the long period, particularly deposit night, can easily bicycle handle bar be unloaded down and take away the bicycle of no handlebar, can't ride away, all extremely difficult even shove along, do not stolen even if there is the bicycle of handlebar, not only target is extremely showy, and be difficult for being equipped with, cartheft is felt simply helpless in addition; Simple in structure, easy enforcement; Do not change the basic structure and the performance of bicycle, bicycle handle bar loads and unloads, carries extremely easy, convenient.

Description of drawings:

Accompanying drawing 1, integral type handlebar 1 and connection pipe 2 integral structure scheme drawings;

Accompanying drawing 2, integral type handlebar 1 and connection pipe 2 split-type structural scheme drawings;

Accompanying drawing 3, split type handle bar structure scheme drawing;

Accompanying drawing 4, brake hanging mechanisms are the coupling type scheme drawing;

Accompanying drawing 5, brake hanging mechanisms are the dial type scheme drawing;

The specific embodiment: further auspiciously in conjunction with the accompanying drawings add explanation.

As shown in Figure 1: bicycle handle bar is whole handlebar 1, and is integral structure with connection pipe 2, and links together by connection pipe 2 and preceding fork adapter 3; The detent mechanism of whole handlebar 1 is as follows: the top of preceding fork adapter 3 has plug 4, and the lower end of connection pipe 2 has supporting jack 5.

As shown in Figure 2: bicycle handle bar is whole handlebar 1, interconnects and be split-type structural with connection pipe 2, and links together by connection pipe 2 and preceding fork adapter 3; The detent mechanism of whole handlebar 1 is as follows: have polarized plug 6 on the whole handlebar 1, and interconnect by the fishplate bar 7 that has on the connection pipe 2 with supporting jack, and the top of preceding fork adapter 3 has plug 4, the lower end of connection pipe 2 has supporting jack 5.

As shown in Figure 3: bicycle handle bar is split type, have left half handlebar 8 and right half handlebar 9, the two can be discrete fully, and the hinge that also can be foldability together, interconnect and be split-type structural, and link together by connection pipe 2 and preceding fork adapter 3 with connection pipe 2; Its detent mechanism is as follows: left and right half handlebar 8 and 9 opposite ends have plug 10 and the jack 11 that complements one another respectively, also has plug 12 on it simultaneously, and interconnect by the fishplate bar 13 that has on the connection pipe 2 with supporting jack, and preceding fork is taken over 3 top, have plug 4, the lower end of connection pipe 2 has supporting jack 5.

Plug 4,6,10 and 12 is prismatic, and corresponding jack is supporting with it, in order to the location.

The plug 4 that the top of preceding fork adapter 3 has, has central through hole, the lower end of preceding fork adapter 3 and the roughly the same ordinary bicycle of captiveing joint of preceding fork 14, also be to realize by hanging egg 15, suspension rod 16 and locknut 17, the end face area of the top plug 4 of fork adapter 3 before locknut 17 then just is positioned at.

Also have corresponding lockout mechanism: can be built-in, also can be external locking-type;

When whole handlebar 1 was integral structure with connection pipe 2, whole handlebar 1 was taken over 3 lockings mutually by handlebar lock 18 and preceding fork;

When whole handlebar 1 was split-type structural with connection pipe 2, the two was by handlebar lock 18 locking mutually, and connection pipe 2 is taken over 3 lockings mutually by taking over lock 19 with preceding fork.

When bicycle handle bar was left and right half handlebar 8 and 9 structures, the two was by handlebar lock 18 locking mutually, and connection pipe 2 is taken over 3 lockings mutually by taking over lock 19 with preceding fork.

Shown in attached Figure 4 and 5, also have the bicycle brake hanging mechanisms, can be coupling type, have hinge hook 21 on the brake lever flap 20, supporting with the movable hook 23 on the brake cable; Also can be dial type, have on the brake lever flap 20 and stir hook 22, supporting with the movable hook 23 on the brake cable.

Using method and antitheft principle:

When whole handlebar 1 is integral structure with connection pipe 2, after the bicycle parking, take brake cable, open handlebar lock 18, can take off whole handlebar 1 together with connection pipe 2.

When whole handlebar 1 is split-type structural with connection pipe 2, or when bicycle handle bar is left and right half handlebar 8 and 9 structures, open handlebar lock 18, can take off bicycle handle bar, when depositing at long period or night, take over lock 19 as long as open, bicycle handle bar and connection pipe 2 can be taken off simultaneously.

The bicycle of no handlebar can't be ridden away, and the adapter 3 of preceding fork is shorter again, and cartheft also is difficult to car is pushed away away, and the bicycle target of this no handlebar is extremely showy, and is difficult for being equipped with, so theftproof performance is very strong.
