Description

Technical Field

[0001] The invention relates to a brake handle structure. Background Art

[0002] As a green means of transportation, bicycles can be seen everywhere in daily life. The brake devices of bicycles, especially the brake cables, have become commonly worn parts.

[0003] The balance of the bicycle itself and the characteristics of the bicycle's body and bracket determine that the bicycle is prone to falling when it is placed. The brake handle is the most common part that falls, which makes the brake cable a vulnerable part.

[0004] Many brake cables are now routed internally, and many handlebars use straight tubing, with some also featuring a bend at the end. This layout makes replacing the brake cable more labor-intensive, making quick cable replacement essential. Summary of the Invention

[0005] The purpose of the present invention is to provide a mobile phone clamp base to address the above-mentioned defects.

[0006] The technical solution adopted by the present invention to solve its technical problem is:

[0007] A brake handle structure includes a locking structure tightly connected to the handlebar, a handle for pulling the brake line, and a connecting piece connecting the locking structure and the handle; the locking structure includes an outer diameter expansion component for locking the locking structure when connected to the handlebar; the outer diameter expansion component includes a hollow bolt, a first locking piece, and a second locking piece, the first locking piece includes a columnar body and a hollow pipe passing through the columnar body; the second locking piece includes a tube body; the connecting piece includes a receiving groove for connecting to the tail end of the handle; a channel connected to the second locking piece is provided in the receiving groove; the handle is connected to the side wall of the receiving groove; the hollow bolt passes through the tube body of the second locking piece and is connected to the hollow pipe of the first locking piece.

[0008] An accommodating cavity is provided on one side or both sides of the first locking member, and a component to be placed is provided in the accommodating cavity;

[0009] When the shape of the accommodating cavity is cylindrical, the component to be placed in the accommodating cavity is a combination of a base and an upper cover, the top of the upper cover has a curved surface with corrugations, and the base is a cylinder with a curved surface on the bottom surface of the cylinder.

[0010] When the shape of the accommodating cavity is a rectangular parallelepiped, the component to be placed in the accommodating cavity is a combination of a base and an upper cover, the top of the upper cover has a curved surface with corrugations, and the base is a rectangular parallelepiped column with a curved surface on the bottom surface.

[0011] When the accommodating cavity is a cylindrical accommodating cavity, the inner wall of the cylindrical accommodating cavity has an inclined surface, the component to be inserted arranged in the accommodating cavity is a steel ball, the diameter of the upper opening of the cylindrical accommodating cavity is larger than the diameter of the steel ball, and the diameter of the lower opening of the cylindrical accommodating cavity is smaller than the diameter of the steel ball.

[0012] When the hollow bolt is screwed into the pipe of the first locking member, the first locking member expands outwards to force the first locking member to be tightly coupled with the inner wall of the handlebar.

[0013] The hollow bolt comprises a bolt body, a bolt head, and a hollow pipe penetrating the bolt body and the bolt head.

[0014] A truncated cone-shaped tail end is provided at the end of the bolt body.

[0015] The second locking member is fixed to one side of the channel of the connecting member.

[0016] One side end of the first locking member is provided with an inclined surface, and one side end of the second locking member is provided with an inclined surface.

[0017] It is worth noting that the arc surface mentioned in the application document is determined according to the required requirements; the outer diameter of the bolt head of the hollow bolt is larger than the inner diameter of the channel in the receiving groove.

[0018] Working principle 1: After the outer diameter expansion component is placed in the tail end tube body of the handlebar, the outer diameter expansion component is connected to the inner wall of the handlebar tube body, and the magnitude of the friction force between the outer diameter expansion component and the inner wall of the handlebar tube body is determined by the magnitude of the expansion force.

[0019] Working Principle 2: As the hollow bolt is screwed into the tube of the first locking member, the first locking member expands outward, forcing it to engage tightly with the handlebar's inner wall. As the hollow bolt is screwed in, the end of the bolt contacts the bottom of the component to be inserted, connecting the top of the component to the inner wall of the handlebar's tail tube.

[0020] Working Principle 3: As the hollow bolt is screwed into the tube of the first locking member, the first locking member expands outward, forcing it to tightly engage the handlebar's inner wall. This tightening of the hollow bolt closes the distance between the first and second locking members, causing their inclined surfaces to contact and shift, causing the first locking member to shift diagonally to one side and connect with the inner wall of the handlebar's tail tube.

[0021] Installation process 1: Pass the hollow bolt through the channel in the accommodating groove and the second locking member, and then screw in the hollow bolt to connect with the first locking member.

[0022] Installation process 2: The brake line is led out from the inner wall of the handlebar, passes through the hollow channel of the hollow bolt, and is connected to the end of the handle.

[0023] Beneficial effects: The provision of the outer diameter expansion component solves the problem of troublesome assembly and disassembly; the trend towards diversified functions of the first locking member increases the flexibility of consumer choice. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] An accommodating cavity 7 is provided on one side or both sides of the first locking member, and a component to be placed is provided in the accommodating cavity;

[0034] When the shape of the accommodating cavity is cylindrical, the component to be placed in the accommodating cavity is a combination 8 having a base and an upper cover, the top of the upper cover has an arc surface with corrugations, and the base is a cylinder 9 with an arc surface on the bottom surface of the cylinder.

[0035] When the shape of the accommodating cavity is a rectangular parallelepiped, the component to be placed in the accommodating cavity is a combination 8 having a base and an upper cover, the top of the upper cover has a curved surface with corrugations, and the base is a rectangular parallelepiped column 10 with a curved surface on the bottom surface.

[0036] When the accommodating cavity is a cylindrical accommodating cavity, the inner wall of the cylindrical accommodating cavity has an inclined surface, and the component to be inserted arranged in the accommodating cavity is a steel ball 11. The diameter of the upper opening of the cylindrical accommodating cavity is larger than the diameter of the steel ball, and the diameter of the lower opening of the cylindrical accommodating cavity is smaller than the diameter of the steel ball.

[0037] When the hollow bolt is screwed into the pipe of the first locking member, the first locking member expands outwards to force the first locking member to be tightly coupled with the inner wall of the handlebar.

[0038] The hollow bolt includes a bolt body 12, a bolt head 13, and a hollow pipe 14 passing through the bolt body and the bolt head.

[0039] A truncated cone-shaped tail end is provided at the end of the bolt body.

[0040] The second locking member is fixed to one side of the channel of the connecting member

[0041] One side end of the first locking member is provided with an inclined surface, and one side end of the second locking member is provided with an inclined surface.

[0042] It is worth noting that the arc surface mentioned in the application document is determined according to the required requirements; the outer diameter of the bolt head of the hollow bolt is larger than the inner diameter of the channel in the receiving groove.

[0043] Working principle 1: After the outer diameter expansion component is placed in the tail end tube body of the handlebar, the outer diameter expansion component is connected to the inner wall of the handlebar tube body, and the magnitude of the friction force between the outer diameter expansion component and the inner wall of the handlebar tube body is determined by the magnitude of the expansion force.
