Description

Technical Field

[0001] This application relates to the technical field of automotive cables, and particularly to a cable joint that can be quickly adjusted. Background Art

[0002] Cables are important components in automobiles. Users operate the control mechanism inside the vehicle to move, and the control mechanism remotely controls the actuator through the cable. Automotive cables generally include shift cables, clutch cables, throttle cables, door cables, brake cables, etc.

[0003] In related technologies, the cable includes a steel wire rope. One end of the steel wire rope is relatively fixed to the shift lever, and the other end is relatively fixed to the swing arm of the gearbox. The joint at the end of the cable near the gearbox includes a ball head sleeve. One end of the steel wire rope is relatively fixed to the ball head sleeve. A bolt is inserted into the ball head sleeve, and the bolt is inserted through the swing arm of the gearbox. A nut is threadedly connected to the bolt. By tightening the bolt and nut, the ball head sleeve is relatively fixed to the swing arm of the gearbox. When the steel wire rope is pulled, the steel wire rope drives the swing arm of the gearbox to move.

[0004] In view of the above related technologies, during the installation of the cable, in order to facilitate the installation by the staff, a certain installation position needs to be reserved between the steel wire rope and the ball head sleeve. After the installation is completed, it is necessary to ensure that the steel wire rope and the ball head sleeve are relatively fixed. Summary of the Invention

[0005] In order to facilitate the installation of the cable and improve the installation efficiency, this application provides a cable joint that can be quickly adjusted.

[0006] The cable joint that can be quickly adjusted provided by this application adopts the following technical solutions:

[0007] A quickly adjustable cable joint comprises a wire rope and a ball sleeve, and further comprises: a fixed block, the fixed block is fixedly connected to the ball sleeve, a stopper is fixed on the side of the fixed block facing away from the wire rope; a positioning rod, one end of the wire rope is fixed in the positioning rod, the positioning rod slides with the fixed block along its own axial direction; a clamping block is used to limit the positioning rod from sliding in the fixed block; a sliding block, the sliding block is located on the side of the fixed block close to the wire rope, the sliding block slides with the fixed block along the radial direction of the wire rope, the positioning rod passes through the sliding block along its own axial direction to form a sliding A groove, wherein one side of the sliding groove is open along the sliding direction of the sliding block and the fixed block, and the positioning rod slides in the sliding groove along its own axial direction and the depth direction of the sliding groove respectively, and the sliding block is also provided with a limit block on one side along the depth direction of the sliding groove for limiting the sliding of the sliding block in the fixed block; an abutment block, wherein the abutment block is arranged between the stop block and the sliding block, and the abutment block is slidably matched with the fixed block along the axial direction of the wire rope, and the fixed block is provided with a driving member for pushing the abutment block to slide, and in the installed state and the working state, different side surfaces on the abutment block are pressed against the sliding block.

[0008] By adopting the above technical solution, the adjustment of the cable joint becomes easier through the mutual cooperation of the fixed block, the positioning rod, the clamping block, the sliding block, the abutment block and the limit block. The sliding design between the sliding block and the fixed block ensures that the positioning rod can slide along the axial direction during adjustment and can also be freely adjusted in the sliding groove. When the staff is installing, they change the relative positions of the sliding block and the abutment block on the fixed block according to different needs. After the staff lets go, the driving member pushes the abutment block to press against the sliding block, thereby preventing the sliding block from moving and fixing the positioning rod and the fixed block relatively. In this way, the staff can quickly adjust the relative position between the ball head cover and the wire rope, which is convenient for installation and helps to improve installation efficiency.

[0009] Preferably, the positioning rod is provided with a plurality of groups of teeth, and the bottom wall of the sliding groove is correspondingly provided with a plurality of groups of teeth, and the two groups of teeth are plugged in along the depth direction of the sliding groove.

[0010] By adopting the above technical solution, the multiple groups of teeth respectively arranged on the positioning rod and the bottom wall of the sliding groove achieve a double fixing effect through the insertion of the teeth, which not only increases the strength of the connection, but also helps to prevent the positioning rod from sliding, ensuring that the positioning rod and the fixing block are relatively fixed.

[0011] Preferably, the limiting block is arranged on one side in the width direction of the sliding groove. A first sliding surface is arranged on the side of the limiting block close to the steel wire rope. The first sliding surface inclines inwards from the side close to the baffle to the side away from the baffle along the axial direction of the steel wire. The abutting block further includes an abutting plate, which is located on the side close to the stop block in the radial direction of the steel wire rope. A third sliding surface is arranged on the side of the abutting plate away from the steel wire rope. The first sliding surface is parallel to the third sliding surface. In the working state, the first sliding surface abuts tightly against the third sliding surface; in the installation state, the side surface of the abutting plate close to the steel wire rope abuts tightly against the side surface of the limiting block away from the steel wire rope.

[0012] By adopting the above technical solution, after the installation is completed, the staff pushes the abutting block towards the side close to the ball head sleeve, and then pushes the sliding block inwards, so that the bottom wall of the sliding groove abuts tightly against the positioning rod. The staff releases the abutting block, and the elastic member pushes the abutting block to move towards the side close to the sliding block. The first sliding surface abuts against the third sliding surface, and the two inclined abutting surfaces are in close contact, providing greater friction to ensure that the cable does not loosen during use. At the same time, during the installation operation, the side surface of the abutting plate close to the steel wire rope abuts tightly against the side surface of the limiting block away from the steel wire rope, thereby ensuring the stability of the sliding block on the fixed block.

[0013] Preferably, a guiding groove is further arranged on the abutting block. The guiding groove penetrates through the abutting block along the sliding direction between the fixed block and the abutting block. The two sides of the guiding groove along the sliding direction between the sliding block and the fixed block are open, and the sliding block is in sliding fit with the abutting block.

[0014] By adopting the above technical solution, the guiding groove helps to ensure the stability between the abutting block and the sliding block when they slide relative to each other on the fixed block.

[0015] Preferably, a second sliding surface is further arranged on the sliding block. The second sliding surface is parallel to the first sliding surface. In the working state, one side edge of the inner side wall of the guiding groove abuts tightly against the second sliding surface.

[0016] By adopting the above technical solution, during the movement of the sliding block, one side edge of the inner side wall of the guiding groove abuts against the second sliding surface and slides along the inclined direction of the second sliding surface, which helps to ensure the stability when the abutting block and the sliding block slide relative to each other.

[0017] Preferably, an embedding groove is arranged on the fixed block. The embedding groove penetrates through the fixed block along the radial direction of the steel wire rope. The sliding block is embedded in the embedding groove. A clamping groove is further arranged on the side of the fixed block close to the abutting plate. The side of the clamping groove away from the steel wire rope is open, and the limiting block is clamped with the clamping groove along the depth direction of the sliding groove.

[0018] By adopting the above technical solution, the limiting block is clamped with the clamping groove, which helps to reduce the movement of the sliding block to the side away from the steel wire rope, thereby preventing the sliding block from disengaging from the fixing block.

[0019] Preferably, a special-shaped groove is provided on the fixing block. The special-shaped groove penetrates into the fixing block from one end close to the steel wire rope along the axis direction of the steel wire rope. The clamping block is a special-shaped clamp. The special-shaped clamp is sleeved on the positioning rod. The special-shaped clamp is slidably matched in the special-shaped groove along the axis direction of the steel wire rope. The special-shaped clamp is located between the abutting block and the sliding block.

[0020] By adopting the above technical solution, the special-shaped groove cooperates with the special-shaped clamp on the positioning rod to ensure that the positioning rod slides in the fixing block along the axis direction of the steel wire rope. The special-shaped clamp is arranged between the abutting block and the sliding block, preventing the positioning rod from disengaging from the fixing block, improving the reliability of the overall installation, and ensuring the stability of the positioning rod during the adjustment process, which helps to facilitate the installation and disassembly.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. Through the sliding and cooperation of components such as the sliding block, the abutting block, and the positioning rod, the user can quickly adjust the relative position between the steel wire rope and the ball head sleeve. The adjustment process is simple and does not require additional tools, greatly improving the installation efficiency;

[0023] 2. Through the insertion design of multiple groups of teeth and the close cooperation between the limiting block and the sliding surface, it is ensured that the cable joint can maintain a firm fixed state after adjustment, preventing sliding or loosening during use, and increasing the reliability of the connection;

[0024] 3. By adopting the embedded groove and special-shaped clamp design, it effectively prevents the positioning rod and the sliding block from disengaging from the fixing block during adjustment or use, ensuring the safety of the entire device during use. At the same time, the guiding groove ensures the smoothness of the sliding process, making the operation more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following is combined with Figures 1-4 This application is described in further detail.

[0031] The embodiment of the present application discloses a quickly adjustable cable joint.

[0032] See also Figure 1 , Figure 2 The quickly adjustable cable joint includes a fixed block 2 and a positioning rod 5. A ball head cover 1 is embedded on one side of the fixed block 2 in the length direction. A special-shaped groove 25 is formed on the fixed block 2. The special-shaped groove 25 penetrates the fixed block 2 from the side away from the ball head cover 1 along the length direction of the fixed block 2. The positioning rod 5 penetrates the special-shaped groove 25 and slides with the special-shaped groove 25 along the length direction of the fixed block 2. A steel wire rope 9 is fixed on the side of the positioning rod 5 away from the fixed block 2, and one end of the steel wire rope 9 is embedded in the positioning rod 5.

[0033] The fixed block 2 is also provided with an embedding groove 23, which penetrates the fixed block 2 along the thickness direction of the fixed block 2. A sliding block 4 is slidably provided in the embedding groove 23, and the length direction of the sliding block 4 is parallel to the thickness direction of the fixed block 2. The sliding block 4 and the fixed block 2 slide together along their own length direction. A sliding groove 41 is formed on the sliding block 4, and the sliding groove 41 penetrates the sliding block 4 inward from the length direction of the sliding block 4, and the sliding groove 41 penetrates the sliding block 4 along the length direction of the fixed block 2. The positioning rod 5 slides and cooperates with the sliding block 4 along the length direction of the sliding block 4 and the length direction of the fixed block 2 respectively.

[0034] See also Figure 3 , Figure 4 The positioning rod 5 is also sleeved with a special-shaped clamp 7, and the special-shaped clamp 7 and the special-shaped groove 25 slide along the length direction of the fixed block 2. The positioning rod 5 is inserted into the sliding groove 41, and the special-shaped clamp 7 is located on the side of the sliding block 4 close to the ball head cover 1. The special-shaped clamp 7 helps to prevent the positioning rod 5 from escaping from the fixed block 2.

[0035] See also Figures 1-4, multiple groups of teeth 6 are formed on the outer surface of the positioning rod 5, and any teeth 6 is annular on the positioning rod 5. Multiple groups of teeth 6 are correspondingly arranged on the bottom wall of the sliding groove 41. The teeth 6 on the positioning rod 5 and the teeth 6 on the bottom wall of the sliding groove 41 are plugged in along the length direction of the sliding block 4. When the teeth 6 on the positioning rod 5 and the teeth 6 on the bottom wall of the sliding groove 41 are plugged in, it helps to prevent the positioning rod 5 from sliding due to the tension of the wire rope 9, thereby ensuring that the positioning rod 5 is relatively fixed to the fixed block 2.

[0036] An abutment block 3 is provided on the side of the sliding block 4 facing away from the steel wire rope 9. A guide groove 33 is provided on the abutment block 3, and the guide groove 33 penetrates the abutment block 3 along the length direction of the fixed block 2. The guide groove 33 is open on both sides along the thickness direction of the fixed block 2. An abutment plate 34 is also formed on the lower side of the abutment block 3, and the thickness direction of the abutment plate 34 is parallel to the width direction of the fixed block 2. A third inclined surface is formed on the side of the abutment plate 34 facing away from the abutment block 3, and the third inclined surface is inclined from the outside to the inside along the length direction of the fixed block 2 from the side close to the ball head cover 1 to the side close to the steel wire rope 9. Two abutment plates 34 are symmetrically provided along the width direction of the fixed block 2.

[0037] A limit block 42 is correspondingly provided at one end of the sliding block 4 along the width direction of the fixed block 2, and the limit block 42 is located at the lower end of the sliding block 4. A first sliding surface 421 is formed on the upper side of the limit block 42, and the first sliding surface 421 is parallel to the third sliding surface 341. Two limit blocks 42 are symmetrically provided along the width direction of the fixed block 2. In the installed state, a side surface of the abutment plate 34 close to the abutment block 3 abuts on the lower side surface of the limit block 42. In the working state, the first sliding surface 421 abuts on the third sliding surface 341. The teeth 6 and the abutting abutment plate 34 and the sliding block 4 help prevent the sliding block 4 from sliding downward on the fixed block 2 along its own length direction.

[0038] The fixed block 2 is also provided with a clamping groove 24, which is located at the lower side of the fixed block 2 in the thickness direction, and the side of the clamping groove 24 facing away from the wire rope 9 is open, and two clamping grooves 24 are provided corresponding to the limit blocks 42. Any limit block 42 is clamped and matched with the corresponding clamping groove 24 along the thickness direction of the fixed block 2. In the working state, the limit block 42 is clamped in the clamping groove 24, which helps to prevent the sliding block 4 from sliding upward on the fixed block 2 along its own length direction.

[0039] The end of the sliding block 4 in the length direction away from the limit block 42 is formed with a second sliding surface 43, and the second sliding surface 43 is parallel to the third sliding surface 341. Two second sliding surfaces 43 are symmetrically arranged along the width direction of the fixed block 2. In the working state, the edge of the side surface of the inner side wall of the guide groove 33 close to the wire rope 9 abuts against the second sliding surface 43.

[0040] On one side of the fixing block 2 close to the ball head sleeve 1 in the length direction, a stop block 21 is also formed. The thickness direction of the stop block 21 is parallel to the length direction of the fixing block 2. On the side of the stop block 21 facing away from the ball head sleeve 1, a first boss 22 is formed. A baffle 31 is also formed on the abutting block 3. The thickness direction of the baffle 31 is parallel to the length direction of the fixing block 2. On the side of the baffle 31 facing away from the steel wire rope 9, a second boss 32 is provided. A driving member is arranged between the baffle 31 and the stop block 21, and the driving member is a spring 8. The two ends of the spring 8 in the axial direction are respectively sleeved on the first boss 22 and the second boss 32. The spring 8 pushes the baffle 31, thereby pushing the abutting block 3 to slide toward the side close to the sliding block 4.

[0041] The implementation principle of a cable joint that can be quickly adjusted in an embodiment of the present application is as follows: During transportation or installation operations, any one of the limiting blocks 42 is clamped in the corresponding clamping groove 24. The side surface of any one of the abutting plates 34 close to the steel wire rope 9 abuts tightly against the lower side surface of the corresponding limiting block 42. The baffle 31 and the stop block 21 compress the spring 8. At this time, the positioning rod 5 can slide along the length direction of the fixing block 2 in the special-shaped groove 25, so that it is convenient for the staff to pull the steel wire rope 9 without changing the position of the ball head sleeve 1. When the staff completes the installation, first push the abutting block 3 toward the side close to the ball head sleeve 1 to further compress the spring 8, and then push the sliding block 4 to slide downward until the first sliding surface 421 is located below the third sliding surface 341. The staff releases the abutting block 3, and the spring 8 elongates, thereby pushing the abutting block 3 to move away from the ball head sleeve 1. The first sliding surface 421 and the third sliding surface 341 abut, and the abutting block 3 pushes the sliding block 4 to continue to slide downward until the teeth 6 on the bottom wall of the sliding groove 41 are inserted into the teeth 6 on the positioning column, and the pushing block stops moving. In the above manner, the sliding block 4 and the positioning rod 5 are respectively fixed relative to the fixing block 2.

[0042] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
