Description

Technical Field

[0001] The present application relates to the technical field of cables, and in particular to a cable assembly that is convenient for adjusting relative length. Background Art

[0002] The cable is an important component in the car, which enables the operating mechanism to remotely control the actuator. The car cables include shift cables, clutch cables, throttle cables, door cables, brake cables, etc.

[0003] In the related art, the cable assembly generally includes a cable body, a sheath, and a fixing member for fixing. The cable body is made of steel wire rope or other high-strength materials. The sheath is wrapped around the outside of the cable body to protect the cable from damage from the external environment. For the convenience of installation, a portion of each end of the cable body is generally exposed outside the sheath. The length of the cable body exposed outside the sheath is the relative length.

[0004] With regard to the above-mentioned related technologies, when the relative length is short, the sheath will affect the overall bending radius and flexibility of the cable. When the relative length is large, the cable exposed outside is easily affected by the external environment. It is urgent to invent a sheath that can adjust the relative length of the rope. Summary of the invention

[0005] In order to facilitate the adjustment of the relative length of the cable body, the present application provides a cable assembly that is convenient for adjusting the relative length.

[0006] The present application provides a cable assembly that is convenient for adjusting relative length, which adopts the following technical solution:

[0007] A cable assembly that is easy to adjust the relative length includes a rope body, two sections of sleeves are provided on the rope body, an adjuster is provided between the two sections of the sleeves, the adjuster includes an adjusting bolt and an adjusting nut, the adjusting bolt and the adjusting nut are respectively fixedly connected to the two sections of the sleeves, a clamping sleeve is also sleeved on the outside of the adjusting nut, the clamping sleeve and the adjusting nut are slidingly matched along their own axial direction, a first fixing component and a second fixing component are provided in the clamping sleeve, and the first fixing component or the second fixing component makes the adjusting nut and the adjusting bolt relatively fixed.

[0008] By adopting the above technical solution, after the cable assembly is produced, the first fixing component fixes the adjusting bolt and the adjusting nut to ensure the relative length of the rope body exposed outside the sleeve, which is convenient for the staff to install the cable. At the same time, it reduces the displacement of the adjusting bolt and the adjusting nut during transportation, which causes wear of the parts inside the cable assembly. After the installation is completed, the staff turns the adjusting bolt and the adjusting nut according to the actual situation, thereby changing the relative position of the two sleeves on the rope body, which helps to reduce the wear of the rope body caused by the external environment during the actual use of the cable. The staff then moves the ferrule, and the second fixing component fixes the adjusting bolt and the adjusting nut, which helps to reduce the position change of the adjusting bolt and the adjusting nut during the actual work of the cable due to the external environment, and helps to improve the stability and safety of the cable assembly during use.

[0009] Preferably, the adjusting bolt includes a head and a threaded portion, a first protrusion is provided on the outer side surface of the head, a plurality of the first protrusions are arranged along the circumference of the axis of the adjusting bolt, a V-shaped groove is formed between any two adjacent first protrusions, and the V-shaped groove passes through the head along the axis direction of the adjusting bolt, and the adjusting nut includes a nut body, one end of the nut body along the axis direction extends outward to form a clamping plate, a clamping block is formed on the clamping plate, the clamping block is embedded in the V-shaped groove and has an interference fit with the V-shaped groove, and two clamping plates are symmetrically provided along the axis of the adjusting nut.

[0010] By adopting the above technical solution, the clamping block and the V-groove are interference fit, and the staff can only change the relative position of the adjusting bolt on the adjusting nut by applying a large external force and turning the adjusting bolt. In this way, it helps to reduce the situation where the relative position of the adjusting bolt or the adjusting nut is changed due to external factors during the transportation or use of the cable assembly, thereby facilitating the transportation of the cable assembly and improving the stability and safety of the cable assembly during use.

[0011] Preferably, the sides of the two clamping plates facing away from each other gradually tilt outward along the side close to the nut body toward the side facing away from the body, and an avoidance groove is provided on the clamping sleeve, and the avoidance groove penetrates the clamping sleeve along the radial direction of the clamping sleeve, and the avoidance groove is open along the side of the clamping sleeve close to the clamping block.

[0012] By adopting the above technical solution, through the interference fit of the clamping block and the V-groove and the outward tilt of the clamping plate, the clamping sleeve needs to overcome greater resistance when sliding. The staff will overcome the greater resistance when pushing the clamping sleeve and push the clamping sleeve to slide on the adjusting nut. However, when transporting or using the cable assembly, vibration or gravity cannot overcome this resistance. This method helps to ensure the fixing effect of the clamping sleeve on the adjusting bolt and the adjusting nut, helps to reduce the possibility of changes in the relative length of the rope body due to external factors, and helps to further improve the stability and safety of the entire cable assembly.

[0013] Preferably, the first fixing component includes a first protrusion, which is formed on a side of the ferrule close to the adjusting bolt. When the side of the first protrusion facing away from the adjusting bolt is pressed against the end face of the nut body, the ferrule, adjusting bolt and adjusting nut are relatively fixed.

[0014] By adopting the above technical solution, the provision of the first protrusion helps to reduce the possibility of the sleeve moving along its own axial direction to the side away from the adjusting bolt, thereby helping to ensure that the adjusting nut and the adjusting bolt are relatively fixed.

[0015] Preferably, the second fixing assembly includes a second protrusion, which is formed on a side of the sleeve close to the adjusting bolt. When the side of the second protrusion close to the adjusting bolt is pressed against the end face of the clamping plate, the sleeve, adjusting bolt and adjusting nut are relatively fixed.

[0016] By adopting the above technical solution, the provision of the second protrusion helps to reduce the possibility of the ferrule moving along its own axis to the side away from the adjusting bolt, thereby helping to ensure that the ferrule, the adjusting nut and the adjusting bolt are relatively fixed.

[0017] Preferably, the adjusting nut body includes a rotating block and a positioning block, the positioning block is located between the rotating block and the clamping plate, the diameter of the rotating block is smaller than the diameter of the positioning block, the second fixing component includes a third protrusion, the third protrusion is located at the end of the ferrule along its own axial direction away from the second protrusion, when the side surface of the third protrusion close to the adjusting bolt is pressed against the end surface of the positioning block close to the rotating block, the ferrule, adjusting bolt and adjusting nut are relatively fixed.

[0018] By adopting the above technical solution, the third protrusion and the positioning block help reduce the possibility of the sleeve moving along its own axial direction toward the side close to the adjusting bolt, thereby helping to ensure that the adjusting nut and the adjusting bolt are relatively fixed.

[0019] Preferably, a first sliding surface is formed inside the ferrule, and a second sliding surface is formed outside the adjusting nut, the first sliding surface and the second sliding surface are parallel, and the first sliding surface and the second sliding surface are slidingly matched along the axial direction of the adjusting nut.

[0020] By adopting the above technical solution, the first sliding surface and the second sliding surface are parallel and slidingly matched, which helps to reduce the possibility of the sleeve rotating around its own axis on the outside of the adjusting nut, thereby helping to ensure that the sleeve fixes the adjusting nut.

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

[0022] 1. The stability of the cable assembly during transportation, installation and use is ensured by adjusting bolts, adjusting nuts, ferrules and their built-in fixing components. It is ensured that when the relative length of the rope body is different, the adjusting bolts and adjusting nuts are in a relatively fixed position, which reduces the change of the position of the casing caused by the influence of the external environment, thereby improving the overall safety and reliability;

[0023] 2. The protrusion and V-groove design on the adjusting bolt and the clamping block of the adjusting nut have an interference fit, so that the adjustment process requires a certain amount of external force, which prevents unintentional loosening due to external factors during transportation and use;

[0024] 3. The steps on the outer sides of each protrusion and the adjusting nut are snapped together to fix the adjusting bolt and the adjusting nut relatively at different positions. This helps to ensure the stability of the adjusting bolt and the adjusting nut and reduces the risk of friction loss and position change. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-6 This application is described in further detail.

[0033] An embodiment of the present application discloses a cable assembly that is easy to adjust the relative length.

[0034] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0035] See also Figure 1 The cable assembly for adjusting the relative length includes a cable body 1, which is made of a steel wire rope or other high-strength materials. Joints 11 are fixed to both ends of the cable body 1 in the length direction. When assembling the car, the staff fixes one end of the joint 11 to the actuator and the other end of the joint 11 to the actuator, and transmits the operating force and displacement to the actuator by human control or electric drive, thereby realizing remote control of the actuator.

[0036] Two sections of sleeves 2 are coaxially sleeved on the rope body 1, and sleeve covers 21 are respectively fixed to the ends of the two sections of sleeves 2 that are away from each other. An adjuster is arranged on the side of the two sections of sleeves 2 that are close to each other, and the adjuster includes an adjusting nut 3 and an adjusting bolt 4, which are respectively arranged on the two sections of sleeves 2. A fixed cover 22 is also arranged between the sleeve 2 on one side and the adjusting nut 3, and the fixed cover 22 is fixedly connected to the end of the sleeve 2 close to the adjusting nut 3, and the fixed cover 22 is connected to the adjusting nut 3 in rotation around the axis direction of the adjusting nut 3.

[0037] See also Figure 1-Figure 6The adjusting nut 3 is coaxially arranged with the wire rope. The adjusting nut 3 includes a nut body 31 and a clamping plate 32. The nut body 31 also includes an integrally formed rotating block 312 and a positioning block 313. The diameter of the rotating block 312 is smaller than the diameter of the positioning block 313. The fixed cover 22 is embedded in the rotating block 312. The positioning block 313 is located on the side of the rotating block 312 away from the fixed cover 22. The clamping plate 32 is located at one end of the positioning block 313 away from the rotating block 312. Two clamping plates 32 are symmetrically arranged along the axis direction of the adjusting nut 3.

[0038] The adjusting bolt 4 includes a head 41 and a threaded portion 42, and the threaded portion 42 of the adjusting bolt 4 is threadedly connected with the threaded portion 42 of the adjusting bolt 4. The head 41 is located on the side of the threaded portion 42 away from the fixed cover 22, and the sleeve 2 on the side away from the fixed cover 22 is embedded in the head 41. A first protrusion is also formed on the outer surface of the head 41, and there are multiple first protrusions in a uniform circumferential array around the axis direction of the adjusting bolt 4, and a V-shaped groove 441 is formed between any two adjacent first protrusions. A clamping block 321 is formed on the side surface of the two clamping plates 32 close to each other, and the clamping block 321 is embedded in the V-shaped groove 441 and has an interference fit with the side wall of the V-shaped groove 441. The staff rotates the adjusting nut 3 to change the relative distance between the adjusting nut 3 and the adjusting bolt 4, thereby controlling the relative distance between the two sections of the sleeve 2 and changing the relative length of the rope body 1 exposed outside the sleeve 2. The interference fit between the clamping block 321 and the V-groove 441 will cause the adjusting nut 3 or the adjusting bolt 4 to encounter a certain resistance when rotating. The staff needs to overcome this resistance during operation. In this way, it helps to reduce the situation where the adjusting bolt 4 or the adjusting nut 3 is affected by external factors and the position changes during the transportation or use of the cable assembly.

[0039] See also Figure 6 A second sliding surface 51 is integrally formed on the nut body 31, and two second sliding surfaces 51 are symmetrically arranged along the axis direction of the nut body 31. The second sliding surface 51 is a plane. A ferrule 5 is also sleeved on the outside of the adjusting nut 3, and a first sliding surface 311 is formed on the inside of the ferrule 5. The first sliding surface 311 is parallel to the second sliding surface 51, and two first sliding surfaces 311 are symmetrically arranged on the ferrule 5 along the axis direction of the adjusting nut 3. The two second sliding surfaces 51 are respectively pressed against the two first sliding surfaces 311. The ferrule 5 and the adjusting nut 3 slide together along their own axis direction.

[0040] The sides of the two clamping plates 32 that are away from each other gradually tilt outward along the side close to the positioning block 313 toward the side away from the positioning block 313. When the clamping sleeve 5 moves to the outside of the clamping plates 32, it will press the two clamping plates 32 inward, thereby increasing the pressure exerted by the clamping block 321 on the side wall of the V-shaped groove 441, resulting in an increase in the friction between the clamping block 321 and the side wall of the V-shaped groove 441, further preventing the relative rotation between the adjusting nut 3 and the adjusting bolt 4.

[0041] See also Figure 2-Figure 4 , the ferrule 5 is also provided with a first fixing component and a second fixing component. The first fixing component includes a first protrusion 52, which is integrally formed at one end of the ferrule 5 in the axial direction. The first protrusion 52 can be arranged in a circular array around the axial direction of the ferrule 5. In this embodiment, two first protrusions 52 are arranged symmetrically along the axial direction of the ferrule 5. The second fixing component includes a second protrusion 53 and a third protrusion 54. The second protrusion 53 and the first protrusion 52 are at the same end of the ferrule 5, and the second protrusion 53 and the clamping plate 32 are arranged correspondingly. The second protrusion 53 can be arranged in a circular array around the axial direction of the ferrule 5. In this embodiment, two second protrusions 53 are arranged symmetrically along the axial direction of the ferrule 5. The third protrusion 54 is located at one end of the ferrule 5 away from the second protrusion 53. The third protrusion 54 can be arranged in a circular array around the axial direction of the ferrule 5. In this embodiment, four third protrusions 54 are arranged evenly spaced. The first protrusion 52 is located on the side close to the adjusting bolt 4, and the third protrusion 54 is located on the side close to the nut body 31.

[0042] See also Figure 2-Figure 3 Before transportation and installation, the staff pushes the ferrule 5 so that the side of the first protrusion 52 close to the positioning block 313 is pressed against the end face of the positioning block 313 away from the rotating block 312, thereby preventing the ferrule 5 from sliding in the direction close to the rotating block 312. The two clamping plates 32 expand outwardly, which is larger than the distance between the inner side walls of the ferrule 5, thereby preventing the ferrule 5 from sliding in the direction away from the rotating block 312. In this way, the ferrule 5, the adjusting nut 3 and the adjusting bolt 4 are relatively fixed, which helps to reduce the change in the relative position between the adjusting bolt 4 and the adjusting nut 3 during transportation or installation.

[0043] See also Figure 4-Figure 5After the installation is completed, the staff pushes the ferrule 5 to make it slide to the side away from the fixed cover 22, so that the side of the second protrusion 53 close to the positioning block 313 is pressed against the side surface of the clamping plate 32 away from the bolt body. The inner side wall of the ferrule 5 presses the two clamping plates 32 inward, thereby increasing the pressure applied by the clamping block 321 on the side wall of the V-shaped groove 441. At the same time, the side of the third protrusion 54 close to the adjusting bolt 4 is pressed against the end face of the positioning block 313 close to the rotating block 312. In this way, the ferrule 5 is prevented from sliding on the outside of the adjusting bolt 4, so that the ferrule 5, the adjusting bolt 4 and the adjusting nut 3 are relatively fixed, which helps to ensure that the relative length of the rope body 1 exposed to the outside of the sleeve 2 is fixed during the use of the car.

[0044] The implementation principle of a cable assembly that is convenient for adjusting the relative length of the embodiment of the present application is as follows: before transportation and installation, the staff tightens the adjusting nut 3 and the adjusting bolt 4 to maximize the relative length of the rope body 1 exposed outside the sleeve 2. The staff pushes the ferrule 5 so that the side of the ferrule 5 close to the adjusting bolt 4 is pressed against the side surface of the two clamping plates 32 tilted outward, and the side of the first boss close to the positioning block 313 is pressed against the end surface of the nut body 31, so that the ferrule 5, the adjusting nut 3 and the adjusting bolt 4 are relatively fixed. When the installation is completed, the staff loosens the adjusting nut 3 and the adjusting bolt 4, and changes the relative position of the adjusting nut 3 and the adjusting bolt 4 according to the actual situation, so as to change the relative length of the rope body 1 exposed outside the sleeve 2. After the adjustment is completed, the staff pushes the ferrule 5 so that the side of the second boss close to the positioning block 313 is pressed against the end surface of the clamping plate 32, and the side of the third boss close to the adjusting bolt 4 is pressed against the end surface of the positioning block 313 close to the rotating block 312. Thus, the ferrule 5, the adjusting nut 3 and the adjusting bolt 4 are relatively fixed.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
