Abstract
The folding bicycle handlebar has one shaft sleeve inside the front support, one rotation axis inside the sleeve of the front support and with one end inside the shaft sleeve and the other end fixed to the rotating handle of the handlebar, one set of mandrels with spring in a holding cavity and with head matched to two limiting holes and tail fixed to screw on the handlebar pipe, and the handlebar pipe with front end slip connected to the handlebar rotating handle. The present invention has simple structure, convenient developing, accurate folding and no influence on braking function.
Description
Technical field
The present invention relates to a kind of tap of bicycle, especially a kind of Foldable bicycle tap.
Background technology
Chinese patent CN200420020195.8 discloses " a kind of handle-bar folding device " its left side, right handgrip respectively with a left side, right sleeve is affixed, a left side, right sleeve all is inserted in the vehicle frame pipe, in the vehicle frame pipe locating piece is set, the locating piece middle part is provided with guide rod and positioning tube, be with spring on the guide rod in the positioning tube, sliding part, retainer, be nested with button on the retainer, sliding part links to each other with engagement device, the vehicle frame pipe, left sleeve, right sleeve, all have notch on the positioning tube, the notch that engagement device passes on the positioning tube can snap in the vehicle frame pipe by the retainer effect, left sleeve, in the notch of right sleeve, with left sleeve, right sleeve and vehicle frame pipe are fixed together.Although this patent is by being provided with technical characterictics such as notch is set on retracing spring, sliding part, retainer and button thereof, the positioning tube, can allow left and right handles folding and be fixed together with the vehicle frame pipe, but this utility model complex structure, inconvenience during use, and influence the brake function of bicycle.
Technical scheme
The purpose of this invention is to provide a kind of folding handle-bar stem of bicycle that is applicable to ordinary bicycle and Folding Bicycle.
Technical scheme of the present invention is achieved in that
A kind of folding handle-bar stem of bicycle is provided, rotating shaft by faucet that is provided with on front frame, the front frame and faucet constitutes, and it is characterized in that: an axle sleeve is arranged in the front frame, and one is placed in the interior rotating shaft of sleeve of front frame, rotating shaft one end places in the axle sleeve, and the rotating shaft other end and leading handler are affixed; Rotating shaft is center rotation around the shaft under leading handler effect, and it is folding to be convenient to tap; In the outward flange of tap handler or the cavity volume that the bonded assembly bolt of rear end plate is constituted bottom outward flange, the push rod of spring that has been equipped with a socket, the push rod head can be with first spacing hole of along continuous straight runs setting on the sleeve of front frame, match along second spacing hole of vertical downward direction setting, the push rod tail end is affixed with the screw rod that is arranged on the faucet, the outer flange surface sliding block joint of faucet front inner wall and leading handler.
Said structure can be used for bicycle about on the tap, about the symmetrical configuration setting of tap.
During folding handle-bar stem, for example use the tap in left side, referring to structure shown in accompanying drawing 1 or the accompanying drawing 2, the pulling faucet, then by faucet, screw rod on the faucet, the common movably assembly of forming of push rod, under external force, outer flange surface along leading handler outwards stretches, and compression places the outward flange of leading handler, the perhaps retracing spring in the cavity volume that is constituted by outward flange bottom bonded assembly bolt of rear end plate, make the push rod apical head break away from first spacing hole gradually, when the stroke that draws faucet made the push rod apical head reach rotatable minimum radius, rotary faucet pipe and assembly thereof drove connected leading handler immediately, the rotation an angle of 90 degrees, unclamp faucet, the push rod top enters second spacing hole, at this moment, faucet and front frame are superimposed, and reach the purpose of folding bicycle tap; When needs launched tap, contrary above-mentioned action can be finished.
Aforesaid folding handle-bar stem of bicycle is characterized in that: described push rod is provided with projection and cooperates with retracing spring.
Aforesaid folding handle-bar stem of bicycle is characterized in that: be connected with faucet handles on the described faucet.
Aforesaid folding handle-bar stem of bicycle is characterized in that: described rotating shaft embeds in the leading handler, and perhaps rotating shaft and leading handler are connected as a single entity.
Of the present invention simple in structure, convenient and swift when cycling need launch tap, safe and reliable, when bicycle did not use, the folding handle-bar stem location was accurate, and it is little to take up room, and does not influence the brake function of bicycle.
Description of drawings
Fig. 1 is that push rod head of the present invention cooperates the part-structure scheme drawing after putting in place with first spacing hole.
Fig. 2 is that the folding 90 degree backs of Fig. 1 are parallel with support and cooperate part-structure scheme drawing after putting in place with second spacing hole.
Fig. 3 is the cross-sectional view of faucet shown in Figure 1 and leading handler connecting bridge.
