[0002] The main function of the wheel rim is to make the wheel set have balanced action in the process of entering and braking. The old wheel rim is made of steel, is heavy, and is easy to rust. Now it has been basically eliminated. The current mainstream sports bicycle wheel rim is mainly made of aluminum alloy or carbon fiber. A small number of them are made of scandium alloy or other materials. According to the style, there are mainly straight edge, hook edge and soft edge wheel rims. At present, the straight edge and hook edge wheel rims are more common.

[0003] For the above technical conditions, there are still defects: the existing bicycle wheel rim directly abuts against the inner tire on the inner recess when in use. The inner tire will deform under pressure, thereby transmitting the force to the wheel rim. At this time, the inner tire may slide along the radial direction of the wheel rim, thereby reducing the use effect of the tire.

[0004] Based on this, the utility model discloses a bicycle wheel rim and tire's close contact structure to solve the above problems. UTILITY MODEL CONTENTS

[0005] The utility model discloses a bicycle wheel rim and tire's close contact structure to solve the above technical problems.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical scheme: a bicycle wheel rim and tire's close contact structure, including wheel rim body, tire body and inner tire, the wheel rim body, tire body and inner tire are all annular, the inner recess is arranged on the wheel rim body, the convex part is arranged on the inner recess, and the convex part is used for abutting against the inner tire.

[0007] By adopting the above technical scheme, the convex part can abut against the inner tire. When the inner tire is deformed under pressure, the convex part can better abut against the inner tire, thereby reducing the deformation of the position of the inner tire away from the convex part and improving the use effect of the tire.

[0008] Preferably, the two side edges of the wheel rim body are provided with abutting parts, one side of the abutting part is provided with a contact surface, and a curved part is arranged on the tire body and can be attached to the contact surface.

[0009] By adopting the above technical scheme, after the tire is installed, the close contact degree of the tire and the wheel rim can be improved.

[0010] Preferably, the bottom of the abutting part has a sealing block, a groove matched with the sealing block is formed on one side of the curved part of the tire body, and the groove and the sealing block can be tightly attached.

[0011] By adopting the technical scheme, the close contact effect of the tire and the rim is further improved.

[0012] Preferably, the sealing block and the groove are both semicircular in shape.

[0013] By adopting the technical scheme, the clamping installation is facilitated.

[0014] Preferably, the bottom edge portion of the tire body is further provided with a fitting portion, which can abut against the edge portion of the inner recess.

[0015] By adopting the technical scheme, the connection effect is increased.

[0016] To sum up, the present application has the following beneficial technical effects: by closely fitting the curved portion on the tire body and the contact surface on the rim body, the tire can be well clamped on the rim, and by clamping between the sealing block and the groove, a good sealing effect is formed between the rim and the tire, thereby improving the subsequent use effect of the tire.
