Description

Folding device for parking bicycle

Technical field

The present invention relates to a kind of bicycle folding device, especially a kind of bicycle folding device when being used for the bicycle parking access.

Background technology

Increase at vehicle, under the situation that road and building site space crowd day by day, the access of parking of bicycle also bothers day by day.At present, the left and right sides handle of most bicycles and stretcher are laterally flat to be stretched, and it is big to take up an area of the space, and when parking with access and the bicycle parked of both sides easily collide with, very inconvenient.In addition, also has a kind of Foldable bicycle, as Chinese utility model patent 88215558.X, applying date 1988.10.24, a kind of folding cycle is disclosed, the girder bar of this folding cycle car body is provided with several collapsible fulcrums, and girder bar and handle, seat support pole, all be to link between the seat support auxiliary rod with moving fulcrum, handle partly adopts a special C shape pipe structure, pedal is through including a pedal, one flap, one pedal rocking arm, wherein pedal is to pass across flap with a spike bar, and the two is combined into one, and flap combines with pole on being fixed on the pedal rocking arm with a bearing.This folding cycle mainly is to be used for collection and carrying aspect, to dwindle collection space and to promote convenient in carrying.Owing to will reach the purpose of reduced volume, it is complicated that the texture ratio Regular Bicycle of this folding cycle is wanted, the cost height; When parking temporarily, all need to fold at every turn, very inconvenient; And the bicycle after folding is erect put stable poor.Therefore, existing this Folding Bicycle can not address the above problem fully.

Summary of the invention

The present invention be to solve bicycle park access the time take up an area of the problem that space bicycle big, that park with both sides easily collides with, a kind of simple in structure, easy to use, folding device for parking bicycle that cost is low is provided.

For realizing that the technical scheme that purpose of the present invention adopts is: a kind of folding device for parking bicycle, comprise bicycle handle, bicycle two limit stretchers, stretcher is by foot-operated pitman arm, rubber is ridden back veneer, rubber is ridden outside plate, the stretcher rotating shaft, the folding rotating shaft of stretcher is formed, the foot-operated back veneer of rubber is movably connected on the foot-operated pitman arm by the stretcher rotating shaft, the bottom of the foot-operated back veneer of rubber is provided with locating plate, two limits are provided with connecting bore, the foot-operated outside plate of rubber flexibly connects by folding rotating shaft of stretcher and the foot-operated back veneer of rubber, is rotary with the axial locking nut on the thread end of the folding rotating shaft of stretcher; Bicycle handle by T shape handle rack, have the brake telescopic tube, positioning and fixing gum cover, lock screw form, two ends of positioning and fixing gum cover are provided with the location lasso, two limits of T shape handle rack transverse tube are fixedly connected with the positioning and fixing gum cover, positioning and fixing gum cover and be connected to telescopic tube with positioning and fixing gum cover bonded assembly T shape handle rack transverse tube outside movable sleeve, the protruding circle that has a circle inward direction to extend in the telescopic tube opening is equipped with lock screw on the telescopic tube.

The width of the left and right sides handlebar of the bicycle that shortens and the width of two edge contraction stretchers all are less than or equal to the width of bicycle saddle cushion.

The width of the left and right sides handlebar of the bicycle that shortens, the width of two edge contraction stretchers, the width of bicycle saddle cushion all are less than or equal to 25 centimetres.

The foot-operated resupinate angle of outside plate of rubber is more than or equal to 90 degree.

The present invention is owing to install upwards folding device additional installing additional on the handlebar of the bicycle left and right sides on the casing bit that can stretch and the bicycle left and right sides stretcher, when bicycle parking, left and right sides handle is inwardly shunk, stretcher is upwards folding, be convenient to depositing and taking out of bicycle on the one hand, on the other hand can reduce space that bicycle parking is taken up an area of.And this apparatus structure is simple, and is easy to use, low cost of manufacture.

The specific embodiment

The invention will be further described below in conjunction with accompanying drawing and embodiment.

Folding device for parking bicycle comprises telescopic bicycle handle, bicycle two edge contraction stretchers.

As shown in Figure 1 to Figure 3, telescopic bicycle handle by T shape handle rack 3, have the brake telescopic tube 1, positioning and fixing gum cover 4, lock screw 2 form.Two ends of positioning and fixing gum cover 4 respectively have a location lasso 5 that raises up, two limits of T shape handle rack 3 straight transverse tubes are screwed and connect positioning and fixing gum cover 4, positioning and fixing gum cover 4 and be connected to telescopic tube 1 with positioning and fixing gum cover 4 bonded assembly T shape handle racks 3 transverse tubes outsides movable sleeve, the protruding circle 6 that has a circle inward direction to extend in telescopic tube 1 opening, the internal diameter of protruding circle 6 is slightly larger than the external diameter of straight T shape handle rack 3 transverse tubes, but less than the external diameter of the location lasso 5 on the positioning and fixing gum cover 4, lock screw 2 is equipped with in opening of telescopic tube 1 in word.

During contraction, lock screw 2 is unclamped, have brake telescopic tube 1 move inwardly into handlebar rubber cover and contact with positioning and fixing gum cover 4 at the end.

When stretching out, telescopic tube 1 is outwards moved to telescopic tube 1 open end run into the location lasso 5 of positioning and fixing gum cover 4 projectioies to convex circle 6, screw 2 then is locked.

To shown in Figure 6, the Folding pedal plate is made up of foot-operated pitman arm 7, the foot-operated back veneer 9 of rubber, the foot-operated outside plate 10 of rubber, stretcher rotating shaft 8, the folding rotating shaft 11 of stretcher as Fig. 4.The foot-operated back veneer 9 of rubber is movably connected on the foot-operated pitman arm 7 by stretcher rotating shaft 8, the bottom of the foot-operated back veneer 9 of rubber is provided with and prevents the foot-operated outside plate of the rubber locating plate 12 of upset downwards, have connecting bore 14 on the two side faces, the foot-operated outside plate 10 of rubber flexibly connects with the folding rotating shaft 11 of the foot-operated back veneer 9 usefulness stretchers of rubber, screw on axial locking nut 13 on the thread end of the folding rotating shaft 11 of stretcher, be used for the axial restraint of the folding rotating shaft 11 of stretcher.

When folding, the foot-operated outside plate 10 of rubber is rotated up along the folding rotating shaft 11 of stretcher, the foot-operated outside plate 10 resupinate angles of rubber can be more than or equal to 90 degree.

The foot-operated width of the width of the left and right sides handlebar of the bicycle that shortens and two edge contractions all is less than or equal to the width of bicycle saddle cushion.The width that the width of the left and right sides handlebar of the bicycle that shortens, two edge contractions are ridden, the width of bicycle saddle cushion all are less than or equal to 25 centimetres.

During bicycle parking that 1 shortening of left and right sides handlebar sleeve pipe and stretcher outside plate 10 is upwards folding, be convenient to inject the parking stall; More convenient the withdrawing from of energy when taking bicycle; Ride with preceding left and right sides handlebar sleeve pipe 1 is stretched to both sides, stretcher outside plate 10 original position of turning back.

This device is produced under the batch state increases by 10 to 15 yuan of costs approximately, can too much influence not arranged to existing customer.
