The utility model discloses a sharing type bicycle front fork, including left side fork and right side fork, the bottom of left side fork and right side fork partly do not is equipped with one and is used for colluding the claw with the flower -drum is connected, collude the claw include the circular arc section and with the straight section of circular arc section intercommunication, the radian of circular arc section is between 270 - 290, straight section is kept away from the one end of circular arc section is open architecture. The utility model discloses can be applicable to ordinary bicycle, utilize quick detach fixed mounting flower -drum, also can be applicable to the climbing bicycle, utilize section of thick bamboo axle fixed mounting flower -drum, therefore enlarged its application range.
Description
Technical field
The utility model relates to bicycle art, particularly a kind of common type bicycle front fork.
Background technology
Front fork is the critical component for connecting wheel hub and vehicle frame, it comprises left fork and right fork, the bottom of left fork and the bottom of right fork are respectively equipped with hook pawl, and hook between pawl and connect flower-drum, the junction hooking pawl and flower-drum is typically designed to semienclosed hatch frame and enclosed cylindrical structure.
Shown in Fig. 1-3, hook the bottom that pawl 2 is located at front fork 1, the junction hooking pawl and flower-drum is designed to hatch frame 11, and hatch frame 11 comprises semicircle segmental arc and the flat segments tangent with semicircle segmental arc.The axle head of flower-drum 3 is entered in semicircle segmental arc by flat segments, and fixes through quick detach (nut 4 and spanner 5).Hatch frame 11 is commonly used to connect common flower-drum, is common on common bicycle.
Shown in Fig. 4-5, hook the bottom that pawl 2 is located at front fork 1, the junction hooking pawl and flower-drum is designed to the cylindrical structure 12 closed, cylindrical structure 12 is commonly used to connecting cylinder axle 6, the axle head of cylinder axle 6 realizes it in cylindrical structure 12 fix by being inserted in, cylinder axle 6 fixes flower-drum, and it is common on mountain bike.
Thus, aforesaid band open type hooks the front fork of pawl or is with the front fork of drum type brake hook pawl all can only be applicable to a kind of bicycle.If user has purchased the front fork that band open type hooks pawl, and the bicycle of user belongs to mountain bike, and so this kind of front fork just cannot match with mountain bike; If user has purchased the front fork that band drum type brake hooks pawl, and the bicycle of user belongs to ordinary bicycle, and so this kind of front fork also cannot mate with ordinary bicycle.
In sum, both front forks aforesaid have some limitations on range of use.
Utility model content
In order to solve the problems of the technologies described above, the purpose of this utility model is to provide a kind of common type bicycle front fork, and it can not only be applicable to common bicycle, also can be adapted to mountain bike, have commonality, expands its range of use.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of common type bicycle front fork, comprise left fork and right fork, the bottom of described left fork and right fork is respectively equipped with a hook pawl for being connected with flower-drum, the flat segments that described hook pawl comprises arc section and is communicated with described arc section, the radian of described arc section is between 270 °-290 °, and described flat segments is open architecture away from one end of described arc section.
Preferably, the radian of described arc section is 280 °.
Preferably, the inwall of described arc section is provided with helicitic texture.
By above technical scheme, the common type bicycle front fork that the utility model provides, it goes for ordinary bicycle, utilizes quick detach to fixedly mount flower-drum, also goes for mountain bike, utilizes cylinder axle to fixedly mount flower-drum.Thus the utility model expands its range of use, and in addition, common type bicycle front fork only needs out the function that can realize two kinds of different bicycle front forks once secondary mould, has thus saved manufacturing cost.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the present embodiment, carry out specifically, clearly and completely describing to the technical scheme in embodiment.
Shown in Fig. 6-8, the utility model embodiment provides a kind of common type bicycle front fork, front fork 1 comprises left fork and right fork, the bottom of left fork and right fork is provided with the hook pawl 2 for being connected with flower-drum, hook pawl 2 flat segments 112 that comprises arc section 111 and be communicated with arc section 111, the radian of arc section 111 between 270 °-290 °, that is, the radian of arc section 111 should be greater than semicircle and be less than full circle, and flat segments 112 is open architecture away from one end of arc section 111.
Shown in Fig. 6-7, when common type bicycle front fork is used for ordinary bicycle, the axle head of flower-drum 3 is entered in semicircle segmental arc 111 by flat segments 112, and fixes through quick detach (nut (for illustrating) and spanner 5), wherein, the size of the size of flat segments 112 and the axle head of flower-drum 3 matches.
When common type bicycle front fork is used for mountain bike, the axle head of cylinder axle is directly inserted in arc section 111, and the size of arc section 111 and the axle head size of cylinder axle match, and the two ends of cylinder axle are fixed by screw, for fixing flower-drum on cylinder axle.Preferably, the radian of arc section 111 is 280 °.Preferably, the inwall of arc section 111 also can be provided with helicitic texture, and accordingly, the axle head of cylinder axle arranges corresponding helicitic texture, and the axle head of cylinder axle is directly screwed into arc section 111, so then without the need to screw stationary magazine creel axle.
The common type bicycle front fork that the utility model provides, it goes for ordinary bicycle, utilizes quick detach to fixedly mount flower-drum, also goes for mountain bike, utilizes cylinder axle to fixedly mount flower-drum.Thus the utility model expands its range of use, and in addition, common type bicycle front fork only needs out the function that can realize two kinds of different bicycle front forks once secondary mould, has thus saved manufacturing cost.
Above-mentioned detailed description of the invention; be only and technical conceive of the present utility model and architectural feature are described; object is to allow the stakeholder being familiar with technique implement according to this; but above said content does not limit protection domain of the present utility model; every any equivalence done according to Spirit Essence of the present utility model changes or modifies, and all should fall within protection domain of the present utility model.
