Description
Technical Field
[0001] This utility model belongs to the field of bicycle accessory technology, specifically relating to a brake cable jacket. Background Technology
[0002] Electric bicycles, as a convenient and low-carbon means of short-distance travel, have become deeply integrated into daily commutes and life. Their safety performance is directly related to the rider's travel safety. Among the core safety components of electric bicycles, the braking system is a crucial link, and the brake cable, as the "transmission link" of braking force, is a core component that determines the braking response sensitivity and reliability. To ensure that the brake cable is protected from rain and dust corrosion during long-term use, and to reduce sliding friction to ensure smooth operation, the outer surface of the brake cable is wrapped with a special protective structure—the brake cable jacket. This jacket serves as both a "protective barrier" for the brake cable and an important supporting component for maintaining the stable operation of the braking system.
[0003] While existing brake cable sleeves have a certain sealing structure between their ends and the brake cable, a single sealing structure cannot balance "protection" and "smoothness": if the seal is too tight, it will increase the sliding resistance of the brake cable, causing brake jamming, a heavy feel, and affecting handling response; if the seal is too loose, the gaps at both ends will become channels for rainwater and dust to enter, causing the brake cable to rust and wear, shortening its service life, and in severe cases even leading to brake failure. It cannot simultaneously ensure safety and practicality. Therefore, a new brake cable sleeve needs to be designed to solve this problem. Utility Model Content
[0004] The purpose of this invention is to provide a brake cable sleeve that solves the problem mentioned in the background art of the difficulty in simultaneously achieving both sealing and smoothness between the two ends of the existing brake cable and sleeve.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a brake cable sleeve, comprising a sleeve body fitted over the outside of the brake cable, including...
[0006] The sealing assembly includes connectors fixed at both ends of the sleeve, a detachable connecting sleeve connected to the outer end of the connector, a rubber sealing ring fixed to the outer end of the connecting sleeve, a fixing head fixed to the outer end of the connector and extending into the inner cavity of the connecting sleeve, and a brush fixed to the inner side of the outer end of the fixing head.
[0007] Preferably, the sealing assembly further includes a chamfered edge, which is formed at the outer edge of the connecting sleeve.
[0008] Preferably, the sealing assembly further includes an adsorption inner sleeve, which is fixed to the inner wall of the connecting sleeve and surrounds the outer side of the fixing head.
[0009] Preferably, the outer surface of the fixing head gradually tapers towards the outer port, and there is a receiving cavity between the fixing head and the adsorption inner sleeve.
[0010] Preferably, the sealing assembly further includes a threaded connecting sleeve, which is fixed at the end of the connecting sleeve away from the rubber sealing ring and is threadedly connected to the outer surface of the connector.
[0011] Preferably, the sealing assembly further includes anti-slip texture, which is formed on the outer surface of the threaded connection sleeve.
[0012] Preferably, the sleeve includes an innermost drag-reducing lubrication layer, a structural support layer sleeved outside the drag-reducing lubrication layer, and an environmental protection layer sleeved outside the structural support layer.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] By setting a sealing component at the end of the sleeve, and through the rubber sealing ring and brush inside the sealing component, it can play the roles of waterproofing and dustproofing respectively. This double-layer protective structure design effectively avoids the problems of a single sealing structure being too tight and stuck or too loose and failing. On the other hand, it can improve the sealing performance between the two ends of the sealing component and the brake cable, which is conducive to the normal use of the brake cable.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example
[0023] Please see Figures 1 to 5 This embodiment of the present invention provides a technical solution: a brake cable sleeve, including a sleeve 100 that is fitted over the brake cable 300, comprising...
[0024] The sealing assembly 200 includes connectors 201 fixed at both ends of the sleeve 100, a connecting sleeve 202 detachably connected to the outer end of the connectors 201, a rubber sealing ring 203 fixed to the outer end of the connecting sleeve 202, a fixing head 204 fixed to the outer end of the connectors 201 and extending into the inner cavity of the connecting sleeve 202, and a brush 205 fixed to the inner side of the outer end of the fixing head 204. When the brake cable 300 slides inside the sleeve 100, the rubber sealing ring 203 can remove water from the surface of the brake cable 300, while the brush 205 can remove dust from the surface of the brake cable 300. Through the double-layer protective structure, the waterproof and dustproof effect between the sleeve 100 and the brake cable 300 is improved.
[0025] In this embodiment, preferably, the sealing assembly 200 further includes a chamfered edge 206, which is formed on the outer edge of the connecting sleeve 202 to facilitate the removal of water from the surface of the brake line 300.
[0026] In this embodiment, preferably, the sealing component 200 further includes an adsorption inner sleeve 207, which is fixed to the inner wall of the connecting sleeve 202 and surrounds the outer side of the fixing head 204. The adsorption inner sleeve 207 is made of microfiber flocked cloth material, which can adsorb the dust cleaned by the brush 205 and prevent it from sticking to the brake line 300 again.
[0027] In this embodiment, preferably, the outer surface of the fixing head 204 gradually tapers towards the outer port, and there is a receiving cavity between the fixing head 204 and the adsorption inner sleeve 207, which facilitates the adsorption inner sleeve 207 to adsorb dust.
[0028] In this embodiment, preferably, the sealing assembly 200 further includes a threaded connecting sleeve 208. The threaded connecting sleeve 208 is fixed to the end of the connecting sleeve 202 away from the rubber sealing ring 203 and is threadedly connected to the outer surface of the connector 201. By rotating the threaded connecting sleeve 208, the connector 201 and the connecting sleeve 202 can be removed, thereby flushing and cleaning the internal dust.
[0029] In this embodiment, preferably, the sealing component 200 further includes anti-slip texture, which is formed on the outer surface of the threaded connecting sleeve 208 to increase friction and facilitate rotation of the connecting sleeve 202.
[0030] In this embodiment, preferably, the sleeve 100 includes an innermost drag-reducing lubrication layer 101, a structural support layer 102 sleeved on the outside of the drag-reducing lubrication layer 101, and an environmental protection layer 103 sleeved on the outside of the structural support layer 102. The drag-reducing lubrication layer 101 is made of modified polytetrafluoroethylene with a solid lubricant coating material, the structural support layer 102 is made of tin-plated high-carbon steel wire and polyester fiber mixed layer material, and the environmental protection layer 103 is made of modified TPU with anti-UV additives and a hydrophobic coating.
