Abstract

The utility model relates to a foldable handle-adjustable bicycle, which belongs to a vehicle field. The utility model mainly comprises a bicycle frame, a bicycle seat, pedals, a front wheel, a back wheel, a left handle and a right handle, wherein, one gear shifting regulator which is connected with a conducting steel rope is arranged on one handle. The end of the conducting steel rope is connected with a positioning pin component. Disconnected structures are arranged on the middle parts of the left handle and the right handle. A left and a right disconnected points are respectively fixed to a left and a right semi-circle gears which are mutually engaged. Positioning holes are arranged in different angular positions around a middle shaft on two gear surfaces. The shaft center of the gear is regarded as a rotating shaft for the left handle and the right handle which can be rotated and fixed alternately in an angle of 90 DEG between a horizontal position and a vertical position. The left handle and the right handle of the bicycle can be freely adjusted and fixed. The utility model has the advantages of smoothness, success and flexibility for bicycle parking and taking in the condition of a narrow gap, and time saving. In addition, a body posture can be adjusted in the process of traveling and fatigue which is caused by the single posture of traveling is reduced.

Description

The bicycle of collapsible adjusting handlebar

Technical field

The utility model belongs to field of vehicles, specially refers to a kind of bicycle of folding handle bar.

Background technology

China is the kingdom of a bicycle, still be remote rural area no matter in numerous noisy city, bicycle all is that people are the most general, the practical vehicle, people are for easy to carry, developed and made folding structure of some vehicle bodies and vehicle frame, the separable structure of wheel, this all is for walking along the street or carries convenience is provided, but in populous place, will be narrow, during crowded parking lot access bicycle, the capital is because as the handlebar of wide peripheral edge portion and mixing of adjacent vehicle, hang to be difficult to put into smoothly or to take out and to have to delay many times and remove to move adjacent vehicle, extrude a slit and put into bicycle to be deposited, inspired the structure of going to develop a kind of reduced width that handlebar can be occupied in person thus, with handlebar to invagination, not only be convenient to access in slit, and in motion, want to allow and ride soon and the body of preceding volt when directly waist lies fallow a moment, also wish with the corresponding raising of the handlebar that separates some, thereby developed the mechanism that regulates the handlebar position while riding at any time, develop more flexible than prior art, the bicycle of collapsible easily adjusting handlebar.

Summary of the invention

The utility model technical issues that need to address, be to deposit at existing bicycle structure, in narrow slit, pass through difficulty when taking from driving, and malleable weak point such as posture by bike not in travelling, and redesign a kind of bicycle of collapsible adjusting handlebar, the purpose of this utility model, rely on following technical scheme to realize, a kind of bicycle of collapsible adjusting handlebar, mainly comprise vehicle frame, vehicle seat, pedal, front and back wheel, left and right sides handlebar, it is characterized in that, a gear shift that is connected with the conduction steel cable is installed on a handlebar regulates bolt device, conduction steel cable end is connected with pin assembly, at the middle part of left and right sides handlebar is open circuited structure, about two cut-off points be separately fixed on the left and right sides semi-circle gear of two mutual interlocks, on two face of gears around axis different angles position, the identical knock hole that has, left and right sides handlebar can be a turning cylinder with the gear axis respectively, rotate in 90 ° between horizontal and vertical position and at interval property fix.Described interval property is fixed, be meant that being subjected to locating dowel pin inserts the aperture on the face of gear and decide, and makes gear in different angles stop, this several position that fixedly is only limited to out aperture, it has certain angle aperture position at interval between 0 to 90 °, will cause handlebar interval, left and right sides property to be fixed.Described conduction steel cable end bonded assembly pin assembly comprises two locating dowel pins that are horse-hof shape, and one section spring is equipped with in its junction, and the spring other end is connected with the conduction steel cable again, and its point of connection is fixedly supported on the similar horse-hof shape mounting.The location aperture that the diverse location place opens on described two face of gears can be selected 30 °, 45 °, 60 °, 85 ° different angles at the middle part of tooth radius, offers the location aperture.

The beneficial effects of the utility model are, this bicycle left and right sides handlebar can free adjustment fixing this bicycle, not only make bicycle parking under the narrow gap condition, pick up the car that it is unobstructed, smoothly and alerting ability to bring, saved the time, and can make the figure be able to adjust between the spare time in the driving process, reduced the volt car fatigue that this single attitude brings of travelling.

Further specify embodiment below in conjunction with accompanying drawing

Fig. 1 is the bicycle structure figure of collapsible adjusting handlebar

Fig. 2 is the Foldable handlebar structural representation

Fig. 3 is the position relation between two halves garden gear and the locating dowel pin.

The specific embodiment

With reference to Fig. 1, represent a whole self-propelled bassinet structure 1, it comprises the open circuited left and right sides, a pair of middle part handlebar 2, be equipped with gear shift control apparatus 3 on the right handlebar, be equipped with in the middle of the handlebar and block board 4, block bridge queen's face two half garden gears 5 of interlock mutually are installed, the diverse location place has aperture 6 on the face of gear, aperture is distributed in the middle part of tooth radius respectively at 30 °, 45 °, 60 ° and 85 ° of different angles places, handle is fixed on level to these intervals between the upright position about can making, fixedly the locating dowel pin of usefulness is 7, it is the shape of a hoof, is a similar shape of a hoof mounting 8 in the periphery of set pin, and Qi Dingchu has fixed orifice 9, by its middle part spring 10 is installed, the spring one end shape of a hoof set pin of ining succession, the conduction steel cable that the other end is ined succession and come out by gear shift control apparatus 3 is used for regulating latch and enters or withdraw from location aperture 6, half gear is being fixed by bolt 11 in termination, middle part at left and right sides handlebar 3, and serves as the axle rotation with bolt position 11 finally.
