Abstract
The utility model relates to an anti-rotating structure of a single-gun shockproof front fork, in particular to a spacing anti-rotating device which utilizes an outer cannula to generate elastic buffer with the stand pipe on a stand pipe of a front fork of a bicycle. Connecting pieces are mainly arranged on the lower end of the outer cannula which is sheathed on the stand pipe and between the top ends of two fork feet, and the connecting pieces are pivoted on the bottom end of the outer cannula to be opposite to one lateral sides of stand pipe seats on the top ends of the two fork teeth through a two-connecting bar-shaped mobile pivoted block in an outer bending shape, and the stand pipe which is designed into a round pipe shape to be sleeved and the axle movement between the inner and the outer cannula surfaces of the outer cannula can be limited by the connecting pieces to reach the purpose of preventing rotation.
Description
Technical field
The utility model system is meant a kind of spacing anti-rotation device that utilizes an outer tube and its generation elastic buffer on the bicycle front fork vertical tube especially relevant for a kind of shock-proof front-fork assembly of bicycle.
Background technology
The front fork of Regular Bicycle is equipped with the shock-absorbing design of various different structures, wherein generally be divided into two kinds of kenels of bitubular type and vertical tube type, and the utility model mainly is at the single-gun-type shock-proof front-fork assembly structure of this vertical tube type improvement design in addition, the general system of its conventional construction is provided with the shock-absorbing purpose that anti-vibration component reaches elastic buffer by the vertical tube joining place of an outer tube and front fork, yet, this kind structure design is when implementing to use, if its outer tube inner edge surface can be easy to generate yaw displacement with the pipe of the fit mutually face that the vertical tube outer edge surface of front fork is made as the pipe shape, and have the dealer that its outer tube inner edge surface and the vertical tube outer edge surface of front fork are made as the polygonal pipe of fit mutually face, yet, because precision can be than the inner and outer pipes face register differences of pipe shape, so often the axial motion when the shock-absorbing effect produces is being deposited stability and the desirable not to the utmost problem of smoothness in the manufacturing of polygonal inner and outer pipes face fit.
Therefore, at the stability and the precision problem of the vertical tube outer edge surface of above-mentioned known bicycle single-gun-type shock-proof front-fork assembly outer tube inner edge surface and front fork, the anxious desire of industry solves and breaks through this difficult problem.
The utility model content
Main purpose of the present utility model is to provide the anti-rotation structure of the single-gun-type shock-proof front-fork assembly of the preferable stability of a kind of tool.
To achieve these goals, the anti-rotation structure of single-gun-type shock-proof front-fork assembly of the present utility model, mainly tie up to one and be sheathed between outer tube bottom on the vertical tube and two fork pin tops and be provided with a connecting piece, this connecting piece system is the outer curved outer tube bottom and two that is articulated in by the movable pivot piece of two link-types and pitches pin tops one side opposite position.
This connecting piece system is the outer curved fixing block set in outer tube bottom and two that is articulated in by the movable pivot piece of two link-types and pitches on the pivot ear at the integrally formed vertical tube seat back side that goes out, pin tops.
This two movable pivot piece generally is the H type and is connected in series mutually, and its two ends place respectively is respectively equipped with the pivot hole.
The one end system of one movable pivot piece is set as the polyphone end of narrower shape, and is inside and outside cover sympodium pivot with another movable pivot piece.
The vertical tube seat one side opposite position system on this outer tube bottom block set and two fork pin tops is formed with the pivot ear.
By above structure, the utility model makes this vertical tube that is made as pipe shape phase fit and the axial motion between outer tube inner and outer pipes face can be limited by this connecting piece and reaches the purpose of anti-rotation.
Description of drawings
For above-mentioned feature and advantage of the present utility model can be become apparent, below lift a preferred embodiment now, and cooperate graphic, figure number, constitution content of the present utility model and the effect reached thereof are described in detail as the back:
Fig. 1 is a block diagram of the present utility model.
Fig. 2 is a three-dimensional exploded view of the present utility model.
Fig. 3 is an action diagram of the present utility model.
Fig. 4 is the local enlarged diagram of Fig. 3.
The specific embodiment
At first, see also Fig. 1, it is the block diagram of anti-rotation structure one preferred embodiment of the utility model single-gun-type shock-proof front-fork assembly, especially refer to a kind of spacing anti-rotation device that on the vertical tube 11 of bicycle front fork 10, utilizes an outer tube 20 and its generation elastic buffer, mainly tying up to one is sheathed between outer tube 20 bottoms on the vertical tube 11 and two fork pin 12 tops and is provided with a connecting piece 30, this connecting piece 30 is the movable pivot piece 31 by two link-types, 32 are the outer curved vertical tube seat 13 1 side opposite positions that are articulated in outer tube 20 bottoms and two fork pin, 12 tops, by this, make axial motion between this vertical tube 11 that is made as pipe shape phase fit and outer tube 20 inner and outer pipes faces can be limited by this connecting piece 30 and reach the purpose of anti-rotation.
Below now with regard to structural attitude of the present utility model, application technology means and expect the effect of reaching, cooperate graphic, describe in detail as after, believe when can to the utility model more deep and concrete understanding being arranged therefrom, as described below:
Continuous please the cooperation shown in the three-dimensional exploded view of consulting Fig. 2, can find out that the utility model mainly ties up to one and is sheathed between outer tube 20 bottoms on the vertical tube 11 and two fork pin 12 tops and is provided with a connecting piece 30, this connecting piece 30 is the movable pivot piece 31 by two link-types, 32 are the outer curved pivot ear 210 that the fixing block set 21 in outer tube 20 bottoms and two is pitched integrally formed vertical tube seat 13 back sides that go out, pin 12 tops that is articulated in, on 130, this two movable pivot piece 31 wherein, 32 generally are the H type is connected in series mutually, its two ends place respectively is respectively equipped with pivot hole 310,310 ', 320,320 ', wherein an end of a movable pivot piece 32 is set as the polyphone end 321 of narrower shape again, system and the pivot hole 310 of running through contraposition mutually inside and outside another movable pivot piece 31 is behind the fit again via a stud shaft 33,320 and compose in series, two movable pivot pieces 31 in addition, external side end pivot hole 310 ' behind 32 polyphones, equally can be on 320 ' via a stud shaft 34,35 are articulated in the vertical tube seat 13 formed pivot ears 210 on outer tube 20 bottom block sets 21 and two fork pin, 12 tops, in 130.
