Description

Single support spring protective sleeve for bicycle Technical Field The utility model relates to the technical field of bicycle supports, in particular to a bicycle single support spring protection sleeve. Background In the existing bicycle single support structure, the springs are usually directly exposed to the external environment and are corroded by pollutants such as dust, rainwater, silt and the like for a long time, rust, elastic attenuation and even fracture of the springs are easily caused, and therefore stability and service life of the support rods are affected. The existing bicycle single-support spring protection sleeve is of a split type structure and is usually composed of a protection sleeve body and an independent plug, the body and the plug are required to be sleeved on a single support rod and a spring respectively during installation, the steps are complicated, the requirement on installation precision is high, users are inconvenient to operate, accurate butt joint is difficult to achieve in a narrow space, friction is generated between the independent plug and a support lug in frequent use to cause loss, loosening or falling occurs, in addition, the body and the plug are required to be processed respectively in the production process of the split type structure, the complexity of a die is increased, the production procedure is long, errors are easy to generate in size matching of split components, and material waste and waste rate are increased. Therefore, there is a need for a protective cover with simple structure, excellent protection performance and improved spring stability, so as to solve the above technical drawbacks. Disclosure of utility model The utility model aims to solve the technical problem that a bicycle single support spring protective sleeve is provided for overcoming the defects in the prior art. In order to achieve the purpose, the utility model adopts the following technical scheme: A bicycle single support spring protective sleeve comprises a protective sleeve main body and a contact part integrally formed with the top of the protective sleeve main body, wherein a cone-shaped accommodating cavity is arranged in the protective sleeve main body, and a limit table is arranged at the top of the accommodating cavity; the insertion cavity inside the contact part is communicated with the accommodating cavity, and the top of the contact part is provided with a bump. Preferably, the protective sleeve main body is sleeved on a single support rod of the bicycle. Preferably, the single support rod is sleeved with a spring, one end of the spring is abutted to a limiting part in the middle of the single support rod, the protective sleeve main body is sleeved outside the spring, and one end of the spring, which is far away from the limiting part, is abutted to the limiting table. Preferably, the top of the single support rod is rotatably connected with a support lug of the bicycle, and the contact part is contacted with the support lug. The utility model has the beneficial effects that: (1) The utility model adopts an integral forming structure of the protective sleeve main body and the contact part, does not need to additionally assemble a body and a plug, can be directly sleeved outside the single support rod and the spring to finish the installation, omits the complex butt joint step of a split structure, obviously improves the installation efficiency and reduces the operation difficulty of users. (2) The method reduces waste materials, improves the utilization rate of materials, abandons the multi-component processing mode of the traditional split structure, completes the integral manufacture through a one-time injection molding or compression molding process, avoids the waste materials generated by the mismatching of the sizes of the split components, reduces the material loss while simplifying the production flow, and meets the requirements of green manufacture and cost control. (3) The integrated protective sleeve has high structural strength and excellent protective performance, and the integrated structure eliminates the weak link of connection of the split protective sleeve and avoids the problem of protective failure caused by loosening of parts. The protective sleeve body wraps the spring, the contact part is in direct contact with the supporting vehicle ear, the integral structure is reliably connected under working conditions such as moving and impacting, and dust prevention, water prevention and wear prevention protection are continuously provided for the spring. (4) The design of the limiting table and the contact part protruding blocks realizes the protection of the spring, and simultaneously takes the limiting effect on the spring and the stable contact with the support vehicle ear into consideration, compared with the mode that independent parts in a split structure respectively realize single functions, the utility model realizes the function integration throu
