Description

Technical Field

[0001] This utility model relates to the field of automotive accessory technology, specifically to a cable distribution box for a roof rack. Background Technology

[0002] Existing roof racks on off-road vehicles typically have both loading and unloading functions, driven by cable transmission. To allow independent operation from the left and right sides for passengers, two input cables are usually installed, corresponding to the left and right handles respectively, without interference between them. Simultaneously, to ensure balanced force, both sides of the roof rack need to move simultaneously, thus requiring two output cables. This allows pulling one input cable to simultaneously activate both output cables, while the other input cable remains stationary.

[0003] The existing branching structure is relatively simple and often cannot achieve the functions of independent input and synchronous output, resulting in inconvenient control and uneven force distribution.

[0004] Based on this, this utility model designs a cable distribution box for a roof rack to solve the above problems. Summary of the Invention

[0005] The purpose of this utility model is to provide a cable distribution box for a roof rack to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cable distribution box for a roof rack, comprising: a base box; a central column is fixedly connected to the inner wall of the base box, and rollers are arranged around the central column inside the base box, with a return spring engaged between the rollers and the central column; The top of the roller is fixedly connected to two symmetrical fixed columns, and the two fixed columns are respectively fixedly connected to a first input steel rope and a second input steel rope. The bottom of the roller is provided with two symmetrical curved slide grooves, and each of the two curved slide grooves is slidably connected to a sliding column. The two sliding columns are respectively fixedly connected to a first output steel rope and a second output steel rope.

[0007] Preferably, a limiting block is fixedly provided at the bottom of the roller, and a curved limiting groove is provided at one end of the central column, with one end of the limiting block slidably disposed in the curved limiting groove.

[0008] Preferably, the roller has an inner concave groove at the connection end of the first output steel rope, the second output steel rope, the first input steel rope, and the second input steel rope.

[0009] Preferably, the top of the base box and the center column are fastened with a snap-fit ​​cover to restrict the rollers to rotate within the base box.

[0010] Preferably, a straight guide tube corresponding to the first output steel rope, the second output steel rope, the first input steel rope, and the second input steel rope is snapped between the bottom box and the cover, for controlling the stable tension of the steel rope.

[0011] Preferably, the ends of the first output steel rope, the second output steel rope, the first input steel rope, and the second input steel rope away from the bottom box are all fixedly connected to snap-fit ​​balls.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: through the cooperation of the roller and the slide column, the first output steel rope and the second output steel rope can drive the roller independently, thereby driving the first input steel rope and the second input steel rope to work synchronously. The stability of the movement is ensured by the limiting mechanism, the return coil spring and the guide structure, realizing the function of independent dual input and synchronous dual output.

[0016] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5 This utility model provides a technical solution: a cable distribution box for a roof rack, comprising: a base box 1; a central column 3 is fixedly connected to the inner wall of the base box 1, and a roller 4 is arranged around the central column 3 inside the base box 1, with a return spring 5 engaged between the roller 4 and the central column 3; The top of the roller 4 is fixedly connected to two symmetrical fixed columns 10, and the two fixed columns 10 are respectively fixedly connected to the first input steel rope 6 and the second input steel rope 7. The bottom of the roller 4 is provided with two symmetrical curved slide grooves 11, and each of the two curved slide grooves 11 is slidably connected to a slide column 12. The two slide columns 12 are respectively fixedly connected to the first output steel rope 8 and the second output steel rope 9. Through the structure of the base box 1, the central column 3, the roller 4, the return coil spring 5, the top fixing column 10 of the roller 4, the curved slide groove 11 at the bottom of the roller 4, and the slide column 12, when the first output steel rope 8 and the second output steel rope 9 are pulled, the roller 4 is driven to rotate. The curved slide groove 11 drives the slide column 12 to make the first input steel rope 6 and the second input steel rope 7 follow, forming a synchronous linkage with the output as the active and the input as the passive, ensuring the balance of force on both sides of the luggage rack and reliable loading and unloading.

[0018] In a further preferred embodiment, a limiting block 14 is fixedly provided at the bottom of the roller 4, and a curved limiting groove 13 is provided at one end of the central column 3, with one end of the limiting block 14 slidably disposed in the curved limiting groove 13; A limiting block 14 is set at the bottom of the roller 4, and a limiting groove is opened at the end of the central column 3. The limiting block 14 slides with the limiting groove to limit the rotation angle of the roller 4, avoid excessive stretching of the input steel rope, prevent the output steel rope from getting tangled, and ensure the safe and reliable operation of the cable distribution box.

[0019] More preferably, the roller 4 has concave grooves at the connection ends of the first output steel rope 8, the second output steel rope 9, the first input steel rope 6, and the second input steel rope 7. The outer wall of the roller 4 has a concave groove. The first input steel rope 6, the second input steel rope 7, the first output steel rope 8, and the second output steel rope 9 are respectively embedded in the groove to run, which prevents the steel rope from falling off or slipping, makes the steel rope evenly stressed, and improves the transmission stability and wear resistance.

[0020] In a further preferred embodiment, the top of the base box 1 and the central column 3 are fastened with a cover 2 by a snap fastener, which restricts the roller 4 to rotate within the base box 1; The bottom box 1 and the top of the central column 3 are snapped together with the cover 2. The cover 2 and the bottom box 1 are closed and fitted together, which reliably encapsulates the roller 4 inside the bottom box 1, preventing foreign objects from entering and affecting the rotation of the roller 4, and keeping the cable distribution box running smoothly. The overall structure is simple and easy to assemble and maintain.

[0021] More preferably, a straight guide tube 15 corresponding to the first output steel rope 8, the second output steel rope 9, the first input steel rope 6, and the second input steel rope 7 is snapped between the bottom box 1 and the cover 2, for controlling the stable tension of the steel ropes; A linear guide tube 15 is provided between the base box 1 and the cover 2. The linear guide tube 15 corresponds to the first input steel rope 6, the second input steel rope 7, the first output steel rope 8 and the second output steel rope 9 respectively, to ensure the linear guiding movement of the steel rope, avoid cross friction, and improve guiding accuracy and operational reliability.

[0022] In a further preferred embodiment, the ends of the first output steel rope 8, the second output steel rope 9, the first input steel rope 6, and the second input steel rope 7 that are away from the bottom box 1 are all fixedly connected with snap-fit ​​balls. The first input steel rope 6, the second input steel rope 7, the first output steel rope 8, and the second output steel rope 9 are all equipped with snap-fit ​​balls at the ends away from the bottom box 1. The snap-fit ​​balls can be quickly connected to external handles or locks to achieve stable fixation of the steel ropes and convenient disassembly and assembly, thereby improving usage efficiency.

[0023] One specific application of this embodiment is: after the ball at the end of the steel rope is inserted into the corresponding device, when it is assembled and used, the roller 4 is kept in a neutral position under the action of the return spring 5, and both the input steel rope and the output steel rope are in a slack state. The first output steel rope 8 on one side is pulled, and the slide column 12 pushes the roller 4 to rotate clockwise, thereby pulling the first input steel rope 6 and the second input steel rope 7 to move synchronously, driving the luggage rack to unfold or retract. On the other side, pulling the second output steel rope 9 drives another slide column 12, and the roller 4 rotates counterclockwise, which in turn pulls the two input steel ropes to complete the same function without affecting the first output steel rope 8. After being released, the return spring 5 resets the roller 4, and the first input steel rope 6 or the second input steel rope 7 returns to its original position, ensuring that the luggage rack is restored.
