Description

A kind of anti-rotation structure of handlebar handle riser

Technical field

The utility model is related to mechanical link, more particularly, to a kind of vertical standpipe for folding bicycle handlebar Anti-rotation structure.

Background technology

Folding bicycle obtains liking for consumers in general with its fast folding or the feature of expansion.When bicycle is folded Afterwards, volume diminishes, and greatly facilitates transport and stores；Can be used safely again after expansion, be easy to people's sport and body-building or ride instead of walk.It is logical Often, inserted with handlebar handle riser connected vertically in sleeve, the sleeve pipe is installed on the front fork lower standing tube of bicycle front end again In, the axial height of handlebar is adjusted by the sliding to axial of handle riser and sleeve pipe.The relative position of handle riser and sleeve pipe Put after adjusting, then be fixedly connected both by a locking device, so that both axially opposing can neither slide and not Can circumferentially opposed rotation.

As shown in figure 1, existing handle riser locks the structural representation of anti-rotation with sleeve pipe.The cylindrical wall edge of handle riser 1 It is axially arranged with great circle arc fluting 2, the Single port of sleeve pipe 7 is provided with beam ring folder 4, can by the set lever 3 of a front end eccentric setting It is adjusted with the internal diameter to beam ring folder 4, to cause handle riser 1 and sleeve pipe 7 to fix or unclamp.Further to limit handle riser 1 and the relative rotation of sleeve pipe 7, may also pass through the wall body of sleeve pipe 7 and one locating piece 5 with small arc surface is set and by a positioning spiral shell The small arc surface of the locating piece 5 is pushed against nail 6 the great circle arc fluting 2 of handle riser 1.When by the way that set lever 3 is by insertion tube 1 and covers Pipe 7 is locked so that the handle riser of handlebar turns into rigid one with the sleeve pipe 7 being fixed in front fork lower standing tube, so that Handlebar flexibly can be accurately rotated, so that the riding bicycle of safety.

Because part is more, and the accumulated error of processing is larger, so that the orthodrome groove surface of handle riser is small with locating piece Arc surface can not fit like a glove all the time so that always leave gap, i.e. handle riser and sleeve pipe always after handle riser and sleeve pipe locking Produce 10⁰~25⁰The relative rotation of left and right.Therefore, the rigidity of attachment means is reduced, standpipe and the loose sense of sleeve pipe is given Feel.It is long and long can also bring potential safety hazard to bicyclist.

By improvement for many years, the defect of a small amount of relative rotation is not all solved really industry always between handle riser and sleeve pipe Certainly, how really to overcome the defect of a small amount of relative rotation between handle riser and sleeve pipe, be industry problem demanding prompt solution.

The content of the invention

In order to solve the above technical problems, the utility model provides a kind of processing simple, safe and reliable to can be used to fold The anti-rotation structure of bicycle handlebar handle riser.

The utility model proposes handlebar handle riser anti-rotation structure, it includes：Upper port is axially arranged with along wall body The sleeve pipe of at least one guide groove, the handle riser inserted in the sleeve pipe, be placed on described sleeve pipe upper port it is cylindrical beam ring folder, be connected to The beam ring presss from both sides the Camlock handle of openend.It is axially disposed on the cylindrical wall of described handle riser to have planar structure；Institute The bushing that an axially open is additionally provided between handle riser and sleeve pipe is stated, the inwall of the bushing is provided with a spacing plane, this is spacing flat Face fits with the planar structure of the cylindrical wall of the handle riser.

Preferably, the transverse width of the spacing plane is 0.5 ~ 0.8 times of the bushing inner diameter.

Preferably, described spacing plane is on the relative internal face of the axially open of the bushing.

Preferably, the outer wall of the bushing is provided with a locating dowel, and the locating dowel passes described sleeve pipe and beam Ring presss from both sides concentric hole, and is connected with a holding screw and described bushing, sleeve pipe and beam ring folder are integrally fixed.

Preferably, described beam ring folder and handle riser are made by extrudate.

Preferably, described bushing is by being molded.

Handle riser of the present utility model is arranged to D-shaped vertical tube structure（Flat axle）, and be provided among handle riser with sleeve pipe The bushing of the spacing plane of one inner wall belt, the spacing plane fits with the planar structure of the handle riser, keeps spacing plane Transverse width limits the relative rotation of handle riser and sleeve pipe so as to can effectively ensure that more than 0.5 times of casing inner diameter.This practicality is new The part of type is few, and mismachining tolerance is small, it is ensured that faying face is fully mated, in addition production cost reduction.Holding screw can be by beam ring Folder, sleeve pipe and bushing link into an integrated entity.The utility model effectively overcomes prior art and connects insecure defect.

Brief description of the drawings

The utility model is described in detail with reference to embodiment and accompanying drawing, wherein：

Fig. 1 is the structural representation that existing handle riser locks anti-rotation with sleeve pipe；
