Description

Technical Field

[0001] The present application relates to the technical field of bicycle accessories, and in particular to a bicycle tube axle quick-release lever. Background Art

[0002] In order to change the wheels quickly and labor-savingly, a quick release device is usually provided at the wheel axle of a general bicycle. The common bicycle wheel quick release device on the market in the early days mainly includes a barrel axle quick release rod, which is inserted into the middle axis of the wheel hub and makes the threaded sections at both ends protrude out of the outside of the front fork or rear fork of the bicycle, and a nut is screwed on the threaded section at one end of the barrel axle quick release rod, and then a clamp is sleeved on the threaded section at the other end of the barrel axle quick release rod, and the threaded section is protruded out of the outside of the clamp, and then a lever is used to screw on the threaded section. In this way, tightening the lever can make the nut and the clamp tighten to the outside of the front fork or rear fork, thereby achieving the purpose of combining and fixing the wheel hub to the front fork or rear fork. Conversely, when the lever is loosened, the wheel hub can be easily and quickly removed from the front fork or rear fork, thereby achieving the purpose of quickly removing the wheel. Among them, a gasket for supporting the end face of the frame is provided on the barrel axle quick release rod, and the gasket and the barrel axle quick release rod are integrated, but this design has a high manufacturing cost.

[0003] Therefore, it is necessary to improve the existing bicycle tube axle quick release rod. Utility Model Content

[0004] The present application provides a bicycle tube axle quick-release lever with low manufacturing cost.

[0005] Specifically, the present application is implemented through the following technical solution: a tube shaft quick-release rod, including a shaft rod and a gasket, the shaft rod is provided with a first end and a second end, the first end is provided with an external threaded section, the gasket is located at the second end, the gasket is separately molded from the shaft rod and riveted fixed to the second end of the shaft rod.

[0006] According to an embodiment of the utility model, the second end is provided with a circle of outwardly protruding steps, and the gasket is riveted outside the steps.

[0007] According to an embodiment of the utility model, the gasket is provided with a step hole matching with the step.

[0008] According to an embodiment of the utility model, the step is provided with an interference rib, and the interference rib is in interference fit with the inner wall of the step hole.

[0009] According to an embodiment of the present invention, the outer diameter of the shaft rod except the step is 16 mm.

[0010] According to an embodiment of the present invention, the overall thickness of the gasket is 5 mm.

[0011] According to an embodiment of the present invention, the outer diameter of the gasket is 20 mm.

[0012] The gasket of the bicycle tube axle quick-release lever of the present application is separately formed from the shaft rod and then fixed by riveting, which can save the material of the shaft rod and reduce the manufacturing cost.

[0013] It should be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a plan view of a bicycle through-axle quick-release lever according to one embodiment of the present application;

[0015] Figure 2 for Figure 1 Enlarged view of the circle.

[0016] Description of reference numerals:

[0017] Axle rod 1 , first end 11 , second end 12 , external thread section 13 , internal hexagon hole 14 , step 15 , main body 16 , interference rib 17 , gasket 2 , step hole 21 . DETAILED DESCRIPTION

[0018] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices, systems, equipment and methods consistent with some aspects of the present application.

[0019] Figure 2 The figure shows the bicycle through-axle quick-release lever of the present application, which includes a shaft rod 1 and a gasket 2. The gasket 2 is manufactured separately from the shaft rod 1 and then riveted and fixed to one end of the shaft rod 1, which can reduce the manufacturing cost of the through-axle quick-release lever.

[0020] The shaft 1 is inserted into the wheel hub of the bicycle wheel, and both ends are embedded in the front fork or rear fork of the bicycle. The shaft 1 is provided with a first end 11 and a second end 12, wherein the first end 11 is provided with an external thread section 13, and the end surface of the second end 12 is provided with an internal hexagonal hole 14, and the gasket 2 is fixed outside the second end 12. The shaft 1 is a solid structure, and as a simple replacement, it can also be a hollow structure.

[0021] The second end 12 of the shaft 1 is provided with a circle of protruding steps 15 at the end surface, and the rest of the shaft 1 is defined as a main body 16. In this embodiment, the outer diameter of the step 15 is about 18 mm, and the outer diameter of the main body 16 is 16 mm. The gasket 2 is riveted from the first end 11 to the step 15 of the second end 12 to be fixed outside the step 15. The gasket 2 can be reliably fixed and will not fall off.

[0022] The gasket 2 forms a step hole 21 corresponding to the step 15, the maximum inner diameter of the step hole 21 is slightly larger than the outer diameter of the step 15, and the minimum inner diameter is slightly larger than the outer diameter of the body 16. The outer end surface of the gasket 2 is flush with the outer end surface of the second end 12. The outer surface of the step 15 is provided with an interference rib 17, and the interference rib 17 interferes with the inner wall of the step hole 21 to reliably fix the gasket 2. The overall thickness of the gasket 2 is about 5 mm, and the outer diameter of the gasket 2 is about 20 mm.

[0023] The gasket 2 of the bicycle tube axle quick release lever of the present application is installed to the shaft rod 1 by riveting and fixing after split molding, which saves the material of the shaft rod 1 compared with the integrated quick release lever, can reduce the manufacturing cost, and also increases the working area of ​​the end face and the bicycle frame. When rotating, the end face of the shaft rod 1 will not directly twist with the end face of the frame, so as to protect the frame.

[0024] The above is only a preferred implementation mode of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the scope of protection of the present application.
