Abstract

The utility model relates to a bicycle, which comprises a bicycle frame, a rear wheel (8), a front wheel (6), and a bicycle saddle (2). The utility model is characterized in that the bicycle frame comprises a front bicycle frame (11) and a rear bicycle frame (12), wherein, the front bicycle frame (11) is provided with an inner pipe (3) of a bicycle crossbeam, and the rear bicycle frame (12) is provided with an outer pipe (1) of the bicycle crossbeam; the inner pipe (3) of the bicycle crossbeam is inserted in the outer pipe (1) of the bicycle crossbeam, and a position locking device is arranged between the outer pipe (1) of the bicycle crossbeam and the inner pipe (3) of a bicycle crossbeam. Therefore, the length of the whole bicycle crossbeam can be adjusted, only the heights of handle-bars and the bicycle saddle are needed adjusting by users, and then, the utility model can be suitable for children in different ages to use.

Description

Bicycle

The utility model relates to a kind of bicycle.

In the prior art, child's bicycle comprises vehicle frame, be arranged at the trailing wheel at described vehicle frame rear portion, be arranged at described vehicle frame front portion front-wheel, be arranged at the vehicle seat on the described vehicle frame.The size of child's bicycle by the diameter of wheel be divided into 12 cun, 14 cun, 16 cun, 18 cun etc. several, with the children's that are applicable to all ages and classes needs, therefore children may need the bigger bicycle of purchase constantly with the growth of height.

The purpose of this utility model is to provide a kind of bicycle that can make the distance change of front-wheel and trailing wheel, uses with the children that are applicable to different age brackets.

The technical solution of the utility model is: a kind of bicycle, comprise vehicle frame, be arranged at the trailing wheel at described vehicle frame rear portion, be arranged at the front-wheel of described vehicle frame front portion, be arranged at the vehicle seat on the described vehicle frame, described vehicle frame comprises front vehicle frame and back vehicle frame, described front vehicle frame is provided with pipe in the car crossbeam that roughly extends in horizontal direction backward, described back vehicle frame is provided with a car crossbeam outer tube that roughly extends in horizontal direction forward, pipe is inserted in the described car crossbeam outer tube in the described car crossbeam, is provided with position local device between the pipe in described car crossbeam outer tube and the described car crossbeam.

The utility model compared with prior art has following advantage:

Because can be flexible relatively between the pipe in car crossbeam outer tube and the car crossbeam, after both being locked with position local device, can make that the length of whole car crossbeam is changed, the user only need regulate the height of handlebar and vehicle seat again, the children that can be adapted to all ages and classes section use, and can save the spending of home shopping.

The utility model will be further described below in conjunction with drawings and Examples:

Accompanying drawing 1 is a structural front view of the present utility model, and header portion wherein is broken away expression.

Accompanying drawing 2 is the A-A direction cutaway view Amplified image of accompanying drawing 1; Wherein:

[1], car crossbeam outer tube; [2], vehicle seat; [3], pipe in the car crossbeam; [4], jack; [5], handlebar; [6], front-wheel; [7], step; [8], trailing wheel; [9], inserted link; [10], oversheath; [11], front vehicle frame; [12], back vehicle frame;

Embodiment: referring to accompanying drawing 1, a kind of bicycle, comprise vehicle frame, be arranged at the trailing wheel [8] at described vehicle frame rear portion, be arranged at the front-wheel [6] of described vehicle frame front portion, be arranged at the vehicle seat [2] on the described vehicle frame, described vehicle frame comprises front vehicle frame [11] and back vehicle frame [12], described front vehicle frame [11] is provided with pipe [3] in the car crossbeam that roughly extends in horizontal direction backward, described back vehicle frame [12] is provided with a car crossbeam outer tube [1] that roughly extends in horizontal direction forward, pipe [3] is inserted in the described car crossbeam outer tube [1] in the described car crossbeam, is provided with position local device between the pipe [3] in described car crossbeam outer tube [1] and the described car crossbeam.

Referring to accompanying drawing 2, described position local device is that pipe [3] upper edge axial array has a plurality of jacks [4] radially in the described car crossbeam, also be provided with jack [4] radially on the described car crossbeam outer tube [1], inserted link [9] passes the jack [4] of managing in the described car crossbeam on [3] last jack [4] and the car crossbeam outer tube [1], and will manage [3] and car crossbeam outer tube [1] relative fixed in the car crossbeam.In the accompanying drawing 2, described inserted link [9] is a bolt, and the end of bolt is provided with nut.A plurality of jacks [4] radially of pipe [3] upper edge axial array with after jack [4] on the car crossbeam outer tube [1] matches, can make the length of crossbeam be stretched respectively in the car crossbeam, crossbeam is adjusted to optimal length uses for children.If have a plurality of jacks on the car crossbeam outer tube [1], and pipe has a jack on [3] and carries out different locking positions and also be fine in the car crossbeam, can think that the equivalence of said structure is replaced.

Also being fine if pipe [3] in the car crossbeam is inserted in car crossbeam outer tube [1], is that structure is replaced in a kind of equivalence of the present utility model.

Be with oversheath [10] on the car crossbeam outer tube [1] at described jack [4] place, avoid the end of inserted link [9] too to protrude and human body is damaged.
