Description

Technical Field

[0001] The utility model relates to the field of bicycle upper tubes, in particular to an upper tube random adjustment device. Background Art

[0002] Bicycles are widely used as a means of transportation and are used for sports and entertainment purposes. There are currently several designs. The basic structure of a bicycle includes a rigid body, a pair of wheels connected to the body, a saddle, a pair of pedal mechanisms, and a steering device. In addition, some designs of bicycles also have a support system with a buffer shock absorber equipped with coil springs around it, which is generally located on the rear wheel or the front wheel, or on both the front and rear wheels; and is integrated with the body; existing bicycles are divided into men's and women's: men's bicycles have a top tube, which is convenient for carrying children and toddlers, and carrying them up and down stairs. But it is not convenient for women to get on and off the bicycle; the top tube of women's bicycles uses an inclined beam or a curved beam to reduce the crossing height from the front, which is convenient for getting on and off, but cannot carry children. The top tube of existing men's bicycles is too smooth, and there is a risk of slipping when carrying people.

[0003] According to the patent application number CN201720614149.8, a bicycle upper tube is provided, including a tube body, a groove is spirally provided on the outer wall of the tube body, and a rubber strip protruding from the groove is fixed in the groove. The utility model has the following advantages and effects: the bicycle upper tube uses a groove arranged on the outer wall of the tube body and arranged in a spiral shape, wherein a rubber strip protruding from the groove is fixed in the groove, and at the same time, a plurality of anti-slip stripes are provided on the outer wall of the rubber strip, when a person sits on the tube body, he can press on the rubber strip, and since the friction coefficient of the rubber material is relatively large, the friction force caused by contact with the human body is relatively large, and finally the possibility of a person slipping off the tube body can be reduced; wherein a plurality of reinforcing ribs are arranged on the inner wall of the tube body, and the reinforcing ribs can increase the strength of the tube body.

[0004] There are still some shortcomings in the patent application. The structural design of the patent is reasonable. However, although the upper tube of the patent increases the friction to prevent people from slipping, the surface is uneven, which makes the person being carried uncomfortable. The upper tube cannot be adjusted, which can easily affect the rider's line of sight and is not conducive to riding safety. Therefore, a top tube free adjustment device is needed to solve these problems. Utility Model Content
