Description
Technical field
The utility model relates to the bicycle field, and particularly a kind of preceding postscript of bicycle with incabloc function adopts the bicycle of this automatic shock-proof front fork.
Background technology
For the cyclist who makes bicycle can comparatively cosily go at broken terrain, a lot of bicycles have all adopted the front fork with incabloc function.The shock-proof front-fork assembly of available technology adopting generally has two kinds of schemes: a kind of is to utilize bilateral elastic body shock-absorbing; Be so-called pair of shock-absorbing; This kind mode is gained in weight greatly, volume is big, cost is high, and profile is not attractive in appearance yet, is not suitable for modern light and handy steamboat footpath car and urban leisure bicycle and uses; Another kind is on the front fork sleeve pipe on front fork shock absorbing apparatus to be set, though its weight is lighter, it adopts circular axle center, cooperates with the front fork cover through two C type clasps, makes C type clasp be inconvenient to locate inconvenient installation, complex structure.
The utility model content
The purpose of the utility model provide a kind of simple in structure, volume is little, lightweight automatic shock-proof front fork.
In order to achieve the above object; The utility model provides a kind of automatic shock-proof front fork; Comprise standpipe of front fork 1, fork blade 2, it is characterized in that said standpipe of front fork 1 lower end is provided with protruded tube 3; Be rotating shaft connecting structure between said protruded tube 3 and the fork blade 2, be provided with shock-proof spring 4 between standpipe of front fork 1 lower end and the fork blade 2.
Further, said rotating shaft connecting structure is: said protruded tube 3 front ends are provided with male joint 5, and said fork blade 2 upper ends are provided with female joint 6, between said male joint 5 and the female joint 6 for being rotationally connected.
Further; Said protruded tube is located at the front of standpipe of front fork 1 lower end; The back of standpipe of front fork 1 lower end is provided with block 7, is provided with bracing frame 8 with cooresponding position, standpipe of front fork 1 lower end on the said fork blade 2, and said shock-proof spring 4 is installed between block 7 and the bracing frame 8.
Further; Said protruded tube is located at the back of standpipe of front fork 1 lower end; The front of standpipe of front fork 1 lower end is provided with block 7, is provided with bracing frame 8 with cooresponding position, standpipe of front fork 1 lower end on the said fork blade 2, and said shock-proof spring 4 is installed between block 7 and the bracing frame 8.
Further, the bottom is provided with briquetting 9 in the said standpipe of front fork 1, is provided with bracing frame 8 with cooresponding position, standpipe of front fork 1 lower end on the said fork blade 2, and said shock-proof spring 4 is installed between briquetting 9 and the bracing frame 8.
Preferably, said block 7 is a tubular structure with support frame as described above 8.
The utility model has also proposed a kind of bicycle, and said bicycle adopts the described automatic shock-proof front fork of above-mentioned each claim.
The automatic shock-proof front fork that the utility model provides, owing to be provided with shock-proof spring at the fork blade midway location, stressed more even, and simple in structure, cost is low.Simultaneously,, when receiving external impact force, reduced stress, thereby prevented the damage of fork blade to a certain extent, prolonged the service life of front fork fork blade because protruded tube cooperates damping with rotating shaft connecting structure between the fork blade with shock-proof spring.

The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As an embodiment of the utility model, as depicted in figs. 1 and 2, a kind of automatic shock-proof front fork; Comprise standpipe of front fork 1, fork blade 2; It is characterized in that the front of said standpipe of front fork 1 lower end is provided with protruded tube 3, is rotating shaft connecting structure between said protruded tube 3 and the fork blade 2; The back of standpipe of front fork 1 lower end is provided with block 7; Be provided with bracing frame 8 with cooresponding position, standpipe of front fork 1 lower end on the fork blade 2, shock-proof spring 4 is installed between block 7 and the bracing frame 8, like this can be better fixing shock-proof spring 4.Rotating shaft connecting structure is: protruded tube 3 front ends are provided with male joint 5, and fork blade 2 upper ends are provided with female joint 6, are rotationally connected between male joint 5 and the female joint 6 with matching.Protruded tube is located at a side of standpipe of front fork 1 lower end, and the shock-proof front-fork assembly of this structure of opposite side of standpipe of front fork 1 lower end has characteristics such as volume is little, in light weight, simple in structure, cost is low.
