Technical Field
[0001] This utility model belongs to the field of brake cable technology, specifically relating to a brake cable with a protective structure. Background Technology
[0002] The existing brake cable is an important component of a car's braking system. Its function is to transmit the force applied by the driver to the handbrake or foot brake to the braking device of the wheels, thereby achieving vehicle deceleration and stopping.
[0003] Existing brake cables, when installed and used, are prone to problems when the main brake cable moves inside the outer protective sleeve. Furthermore, the end of the outer protective sleeve is not easily sealed, allowing water and dust to easily enter. This water and dust ingress can cause corrosion of the main brake cable and obstruction of contact between the main brake cable and the inner surface of the outer protective sleeve. Consequently, the brake cable's pulling stroke is limited during braking, failing to achieve effective braking. This also affects the ease of sealing and lubrication between the brake cable and the main brake cable inside the outer protective sleeve when braking on an electric bicycle. Therefore, this invention proposes a brake cable with a protective structure. Utility Model Content
[0004] The purpose of this utility model is to provide a brake cable with a protective structure to solve the problem mentioned in the background art that when the brake cable is used after installation, the end of the outer protective sleeve is not easy to seal and protect, and water and dust can easily enter into the inside. When water and dust enter, the internal main brake cable is easily corroded and the contact between the dust and the inner surface of the outer protective sleeve is obstructed. Therefore, when braking, the brake cable has a small pulling stroke and cannot achieve an effective braking state.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a brake cable with a protective structure, including an outer protective sleeve, the brake main cable passing through the inside of the outer protective sleeve, connectors being pressed and fixed at both ends of the outer protective sleeve, a sealing and lubrication mechanism being provided at the connection between the inside of the outer protective sleeve and the inside of the connectors, and a wear-resistant protective mechanism being provided on the outer surface of the outer protective sleeve.
[0006] The sealing and lubrication mechanism includes a lubrication assembly that fills the space between the inside of the outer protective sleeve and the surface of the brake main line. The end of the connector is provided with a mounting assembly, and the mounting assembly is provided with a sealing assembly inside.
[0007] The wear-resistant protection mechanism includes wear-resistant protective components installed on the outer surface of the outer protective sleeve.
[0008] Preferably, one end of the brake main line is fixed with a locking pin one, and the other end of the brake main line is fixed with a threaded rod. A locking pin two is fitted onto the outer surface of the threaded rod, and an adjusting nut is threadedly connected to one side of the locking pin two on the outer surface of the threaded rod.
[0009] Preferably, a mounting plate is fixed to the connector surface at the bottom end of the outer protective sleeve, and a return spring is fitted at the connection between the end of the brake main line and the outer surface of the threaded rod.
[0010] Preferably, the lubrication assembly includes a ceramic lubricant applied to the outer surface of the brake mainline, and the ceramic lubricant extends into the interior of the outer protective sleeve and contacts the inner surface.
[0011] Preferably, the mounting component includes an internal threaded groove formed inside the connector, and the internal threaded groove and the interior of the connector are an integral structure.
[0012] Preferably, the sealing assembly includes an externally threaded cylinder that is threadedly connected to the inside of the connector via an internally threaded groove. A sealing post is engaged inside the externally threaded cylinder, and the end of the sealing post is level with the surface of the externally threaded cylinder and contacts the bottom end of the internally threaded groove.
[0013] Preferably, the wear-resistant protective component includes an integrally formed wear-resistant protrusion strip on the outer surface of the outer protective sleeve, and the wear-resistant protrusion strip has an arc-shaped structure.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] By designing a sealing and lubrication mechanism, the external threaded cylinder can be rotated and fixed inside the internal threaded groove until the end of the sealing column is squeezed into contact with the bottom of the internal threaded groove for sealing. At the same time, the brake main cable passes through the inside of the sealing column and makes tight contact. The end of the connector and the brake main cable are sealed by the sealing column, which prevents water and dust from entering the outer protective sleeve during braking. When braking, the brake main cable moves inside the outer protective sleeve and is lubricated by ceramic lubricant, which facilitates sealing and lubrication, reduces friction and prevents corrosion and obstruction of the brake main cable, extends service life, and allows for precise braking with a certain stroke. It also improves the convenience of sealing and lubricating the connector and the inside of the outer protective sleeve after the brake cable is installed and used. Attached Figure Description

Detailed Implementation
[0024] 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.
[0025] Please see Figures 1 to 7 This utility model provides a technical solution: a brake cable with a protective structure, including an outer protective sleeve 101, a brake main cable 102 passing through the inside of the outer protective sleeve 101, connectors 104 being pressed and fixed at both ends of the outer protective sleeve 101, a locking post 103 being fixed at one end of the brake main cable 102, a threaded rod 108 being fixed at the other end of the brake main cable 102, a locking post 106 being fitted onto the outer surface of the threaded rod 108, an adjusting nut 107 being threadedly connected to one side of the locking post 106 on the outer surface of the threaded rod 108, an mounting plate 105 being fixed onto the surface of the connector 104 at the bottom end of the outer protective sleeve 101, and a return spring 109 being fitted onto the connection between the end of the brake main cable 102 and the outer surface of the threaded rod 108.
[0026] A sealing and lubrication mechanism is provided at the connection between the interior of the outer protective sleeve 101 and the interior of the connector 104. The sealing and lubrication mechanism includes a lubrication component that fills the space between the interior of the outer protective sleeve 101 and the surface of the brake main cable 102. An installation component is provided at the end of the connector 104. The installation component contains a sealing component. When the brake cable is installed and used, the sealing and lubrication mechanism can seal and protect the end of the connector 104 and lubricate the space between the interior of the outer protective sleeve 101 and the brake main cable 102, thus facilitating effective braking.
[0027] In order to facilitate the lubrication and movement of the brake main cable 102 inside the outer protective sleeve 101 through the lubrication component, in this embodiment, preferably, the lubrication component includes a ceramic lubricant 1044 applied to the outer surface of the brake main cable 102, and the ceramic lubricant 1044 extends into the interior of the outer protective sleeve 101 and contacts the inner surface. When the brake main cable 102 moves inside the outer protective sleeve 101, it is lubricated by the ceramic lubricant 1044, which is less likely to cause friction and obstruction, and allows for precise braking with less obstruction.
[0028] In order to facilitate the installation of the sealing column 1043 by rotating the externally threaded cylinder 1041 through the installation component, in this embodiment, preferably, the installation component includes an internal thread groove 1042 formed inside the connector 104. The internal thread groove 1042 and the interior of the connector 104 are an integral structure, and can be rotated and installed inside the internal thread groove 1042.
[0029] To facilitate the sealing installation of the brake main cable 102 and the end of the connector 104 using a sealing assembly, in this embodiment, preferably, the sealing assembly includes an externally threaded cylinder 1041 threadedly connected to the inside of the connector 104 via an internally threaded groove 1042. A sealing post 1043 is engaged inside the externally threaded cylinder 1041, and the end of the sealing post 1043 is at the same height as the surface of the externally threaded cylinder 1041 and contacts the bottom end of the internally threaded groove 1042. The sealing post 1043 can be engaged inside the externally threaded cylinder 1041, and after being rotated and installed inside the internally threaded groove 1042, it contacts the outer surface of the brake main cable 102 for sealing installation, thus facilitating sealing and protection.
[0030] The outer surface of the outer protective sleeve 101 is provided with a wear-resistant protection mechanism, which includes wear-resistant protection components disposed on the outer surface of the outer protective sleeve 101. When the brake cable is installed on an electric bicycle, the wear-resistant protection mechanism provides wear-resistant protection to the outer surface of the outer protective sleeve 101, thereby extending its service life.
[0031] In order to facilitate wear protection of the outer surface of the outer protective sleeve 101 and prevent friction damage through the wear-resistant protective component, in this embodiment, preferably, the wear-resistant protective component includes a wear-resistant protrusion 1011 integrally formed on the outer surface of the outer protective sleeve 101, and the wear-resistant protrusion 1011 has an arc-shaped structure, so that the outer surface of the outer protective sleeve 101 can be protected against wear by the wear-resistant protrusion 1011. When the car or the contact frame is worn, the wear-resistant protrusion 1011 protects against wear and extends the service life.
[0032] The working principle and usage process of this utility model are as follows: When using this type of brake cable with a protective structure, firstly, the bottom end of the outer protective sleeve 101 is fixedly installed on the electric bicycle by the mounting plate 105. The first clamp 103 clamps the top end of the main brake cable 102 onto the brake handle. The second clamp 106 is installed at the connection end with the brake component. The adjusting nut 107 on the surface of the threaded rod 108 is rotated to squeeze the second clamp 106, so that the main brake cable 102 is tightened and a certain braking degree is adjusted. Therefore, when using, squeezing the handle will drive the main brake cable 102 to pull the second clamp 106 and the brake component to brake.
[0033] Then, when the brake cable is installed and used, the outer surface of the outer protective sleeve 101 is in contact with the electric bicycle frame. Therefore, when braking and riding, the wear-resistant protrusions 1011 on the outer surface provide wear protection, making it less likely to cause surface friction damage to the outer protective sleeve 101. This provides continuous wear protection, extends the service life, and improves the convenience of wear protection for the outer surface of the outer protective sleeve 101 when the brake cable is installed and used.
[0034] Finally, during the pre-use installation of the brake cable, the sealing post 1043 is engaged inside the external threaded cylinder 1041, and the external threaded cylinder 1041 is rotated and fixed inside the internal threaded groove 1042 until the end of the sealing post 1043 is pressed against the bottom of the internal threaded groove 1042 for sealing. Simultaneously, the brake main cable 102 is passed through the sealing post 1043 and tightly connected. Therefore, during use after installation, the end of the connector 104 and the brake main cable 102 are sealed together by the sealing post 1043, and the brake cable is then properly secured. When the vehicle is in use, it is not easy for water and dust to enter the interior of the outer protective sleeve 101. At the same time, when the brake main cable 102 is pulled and displaced inside the connector 104 and the outer protective sleeve 101, the brake main cable 102 is lubricated inside the outer protective sleeve 101 by ceramic lubricant 1044, which facilitates sealing and lubrication, reduces friction and prevents the brake main cable 102 from rusting and obstructing, extends service life, and improves the convenience of sealing and lubricating the interior of the connector 104 and the outer protective sleeve 101 when the brake cable is installed and used.
[0035] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
