Description

The folding bicycle of being convenient to park

The utility model relates to a kind of bicycle, the bicycle of being convenient to park that especially a kind of energy is folding.

Because bicycle brings many convenience and benefit can for the people that go out, so, both be the current society that increases at traffic prosperity, automobile, bicycle is still the maximum walking-replacing tool of a kind of quantity of China, therefore, parking of bicycle is a very important problem.Concerning the extremely limited city of land used, more impossible building built large-area bicycle parking canopy especially, so there are many problems in existing parking of bicycle.Overstocked as stopping between the bicycle, pick up the car often to be hooked and to be difficult to and take out by handle grip for bicycle or stretcher, wound own sometimes or other people, sometimes other bicycle is knocked over, can not bring convenience to people, damage bicycle again easily.Moreover existing bicycle is divided in men's style and woman style two kinds, and this also brings inconvenience to the bicyclist, therefore, is badly in need of existing bicycle is improved.

The purpose of this utility model is to provide a kind of can make handle grip for bicycle and stretcher folding of bicycle, so that park or the access bicycle.

The bicycle that provides a kind of spider variable is provided another purpose of the present utility model, so that make it to be transformed into man style or lady's bicycle as required.

The technical solution of the utility model is: it comprises vehicle frame, wheel, handrail, stretcher, Transmission, it is characterized in that handrail is a folding arm rest, and stretcher is a Foldable pedal.Described folding arm rest is made of handle, handle frame, attaching parts, and Foldable pedal is made of step block and pin.Wherein the handle frame lower end is fixedly connected on the frame-front fork axle, so that left-right rotation thereupon, be connected with two handles by gear on the handle frame, and these two handles can rotate around pin, after making handle folding forward or backward, become a line with vehicle frame and, be convenient to bicycle parking no longer to the both sides elongation; Also can connect two handles on the handle frame in addition, handle be folded back, and become a line with vehicle frame by pin; Step block is connected with connecting rod on turning axle by pin, and does folding swing around pin, is close to after folding and turns on the axle, and parallel with vehicle frame, so that the parking of bicycle.

Another technical scheme of the present utility model is: it comprises vehicle body, wheel, handrail, stretcher, attaching parts, and the spider that it is characterized in that vehicle body is a bolt cam frame.Described bolt cam frame is by back stay that is connected with seat and the lower fulcrum bar that is connected with preceding fork shaft, and one end and preceding fork shaft flexibly connect, the upper rack posts that the other end can move on back stay constitutes, by moving of this upper rack posts, make spider constitute in men's style vehicle frame or woman style vehicle frame, so that as required as in men's style bicycle or lady's bicycle effect.

The utility model compared with prior art has following advantage and extremely long-pending effect: because bicycle handrail and stretcher are made as accordion structure, therefore can significantly reduce the bicycle width, both be convenient to park bicycle, can avoid mutual collision of bicycle and personnel to wound again, can greatly reduce floor area simultaneously.Because bicycle tripod is movable connection, therefore can bicycle be transformed in men's style bicycle or lady's bicycle use, thereby bring many convenience as required in addition to the user.

Fig. 1 is the armrest scheme drawing of the utility model;

Fig. 2, Fig. 3 are another armrest scheme drawing of the utility model;

Fig. 4, Fig. 5 are the stretcher structural representation of the utility model;

Fig. 6, Fig. 7 are the tripod structure scheme drawing of the utility model.

The embodiment that provides below in conjunction with accompanying drawing is described further the utility model, but content of the present utility model is not limited only to this.

Among Fig. 1,1 is handle frame, and its lower end is fixedly connected on the bicycle front fork axle, and can rotate with the left-right rotation of front fork, so that realize turning of bicycle, 2 is handle, be provided with two, be fixed on the handle frame 1, and rotate around connected nail 3 by connected nail 3, the end of handle 2 is provided with tooth bar 4, and matches with gear 5 on the handle frame 1, is used to adjust the angle of handle 2, the angular range of its adjustment is 180 degree, after rotating 90 degree forward or backward, make handrail parallel, realize the folding of handrail with vehicle body.

Among Fig. 2, Fig. 3, two handles are fixedly connected on the handle frame 1 by pin 6, and rotate around pin 6, and the scope of its rotation is 90 degree, and rotation 90 degree backs are parallel with vehicle body, realize the folding of handrail.

Among Fig. 4, Fig. 5,7 for bicycle turns axle, and 8 for being located at the connecting rod that turns axle 7 terminations, and 9 is pin, by this pin step block 10 is connected on the connecting rod 8, and step block 10 is rotated around pin 9, realizes the folding of stretcher.

Among Fig. 6, Fig. 7,11 is back stay, and its upper end is connected with seat, and the lower end is connected with lower fulcrum bar 12, the other end of lower fulcrum bar 12 is connected with preceding fork shaft 13, upper rack posts 14 1 ends are movably connected on the preceding fork shaft 13 by pin 15, and can rotate around pin 15, and the other end is connected with back stay 11 by pin 16, constitute in men's style spider, link to each other with back stay by pin 17, constitute woman style spider, therefore a car can many people use.
