[0002] The wiring harness is the overall service equipment for a certain load source group, such as relay lines, switching devices, control systems, etc.; according to different structures, it is divided into full utilization wiring harness, partial utilization wiring harness and link system; according to different service methods, it is divided into loss-controlled wiring harness and waiting-controlled wiring harness (see random service system); according to the number of load sources served, it is divided into unlimited load source wiring harness and limited load source wiring harness. In modern cars, electronic control systems are closely related to wiring harnesses. Someone once made a vivid metaphor: microcomputers are equivalent to human brains, sensors are equivalent to sensory organs, and actuators are equivalent to motor organs, so wiring harnesses are nerves and blood vessels.

[0023] In this example, the clamping mechanism also includes a slider 10, and the slider 10 is symmetrically arranged at symmetrical positions in the slide groove 9. The rack 16 and the rack 27 are fixedly connected to the slider 10 on one side near the end of the gear 14. A fixing block 11 is provided on the top of the slider 10, and the fixing block 11 is fixedly connected to the clamping block 2. A pull rod 12 is connected to the side of the slider 10 away from the gear 14, and one end of the pull rod 12 passes through a side wall of the base 1. Springs 13 are symmetrically arranged on the relative outer sides of the two sliders 10 in the slide groove 9, and one side spring 13 is sleeved on the outer side of the pull rod 12. In this example, when the clamping block 2 clamps the wiring harness of the minimum size adapted by the device, a spacing is left between the slider 10 and the inner wall of the slide groove 9 near the gear 4 side to ensure that it can adjust the clamping force. Through the clamping mechanism, the wiring harness can be clamped and fixed conveniently and quickly, and the clamping limit can be adaptively performed according to wiring harnesses of different sizes. It is easy to operate and more practical. In this example, the adjustment component also includes a rotating shaft 15, and the slider 10 is rotatably installed between the two support blocks 14, one end of the rotating shaft 15 passes through the support block 14 to connect the handle, the outer wall of the rotating shaft 15 is sleeved with a gear 2 16, a plurality of tooth grooves are opened on the top of the pull rod 12, and the tooth grooves are meshed with the gear 2 16, and a mounting block 17 is symmetrically provided above the rotating shaft 15 at one end of the base 1, and a rotating rod 18 is rotatably installed between the mounting blocks 17, a clamping block 19 is sleeved on the outer wall of the rotating rod 18, and one end of the clamping block 19 is meshed with the gear 2 16, and a torsion spring 20 is symmetrically provided on the outer side of the rotating rod 18, and the torsion spring 20 is located on both sides of the clamping block 19, and the two ends of the torsion spring 20 are respectively fixedly connected to the rotating rod 18 and the mounting block 17. Through the adjustment component, the force of the clamping block 2 on the clamping harness can be adjusted as needed, thereby changing the tightness of the clamping of the harness. In this example, rack 1 6 and rack 2 7 have the same structure, and rack 1 6 and rack 2 7 are arranged in a circumferentially equidistant array. The combination of rack 1 6, rack 2 7 and slider 10 is L-shaped, so as to synchronously drive rack 1 6 and rack 2 7 to move in a relatively outer or inner direction. In this example, the cross section of the slide 9 is a convex shape, the combined structure of the slider 10 and the fixed block 11 is adapted to the slide 9, the two ends of the spring 13 are respectively fixedly connected to the slider 10 and the inner wall of the slide 9, and the pull rod 12 is located at one end outside the base 1 and is connected to a handle to guide and limit the slider 10 and the fixed block 11. The use of the spring 13 can provide power for the clamping block 2 to move to the middle position of the base 1. In this example, the rotating shaft 15 and the rotating rod 18 are rotatably connected to the support block 14 and the mounting block 17 respectively through bearings. The clamping block 19 is an arc-shaped structure. One end of the rotating rod 18 passes through the support block 14 and is connected to a twist handle so as to support and limit the rotating shaft 15 and the rotating rod 18 without affecting their self-rotation. The twist handle facilitates twisting the rotating rod 18 to drive the clamping block 19 to rotate.The working principle of the utility model is as follows: when in use, the torsion handle is twisted to drive the rotating rod 18 to rotate, and the rotating rod 18 will drive the card block 19 to rotate, so that it is separated from the gear 2 16, and the rotating rod 18 will twist the torsion spring 20, and then the connected pull rod 12 is driven by pulling the handle to pull the connected slider 10 to slide in the slide groove 9, and the slider 10 will drive the connected rack 16 to slide in the track groove 8, and the rack 16 will drive the gear 14 meshing with it to rotate, and the gear 14 will drive the rack 27 meshing with it to move in the track groove 8, and the rack 27 will drive the slider 10 connected at one end to move synchronously, so that the two sliders 10 will move synchronously to the relative outer directions The slider 10 moves and squeezes the spring 13. At the same time, the slider 10 drives the connected clamping block 2 to move synchronously on the top of the base 1 through the fixing block 11. After the clamping block 2 moves to a suitable position, the wiring harness to be limited and fixed is placed between the clamping blocks 2 and corresponds to the arc groove 3. Then, the force applied to the handle is released, so that the slider 10 resets under the elastic force of the spring 13, thereby driving the clamping block 2 to reset and clamp the wiring harness, so that it can adaptively clamp and fix wiring harnesses of different sizes, and the operation is convenient. When it is necessary to adjust the force of the clamping block 2 to clamp the wiring harness, the handle can be twisted to drive the rotating shaft 15 to move away from the base 1. At the same time, the rotating shaft 15 can be rotated to move The shaft 15 will drive the gear 2 16 to rotate. When the gear 2 16 rotates, its teeth will squeeze and push one end of the meshing block 19, so that the block 19 drives the rotating rod 18 to rotate upward, thereby separating the block 19 from the gear 2 16. When the rotating rod 18 rotates, the torsion spring 20 will be twisted. When the teeth squeezing the block 19 on the gear 2 16 are misaligned with it, the rotating rod 18 will reset under the torsion of the torsion spring 20 and mesh with the gear 2 16 again, and so on. When the gear 2 16 rotates, it will cooperate with the tooth groove meshing with it to drive the pull rod 12 to move into the slide groove 9, so that the block 19 pushes the slider 10 to move, and cooperates with the rack 1 6, gear 1 4 and gear The transmission of bar 2 7 causes the two clamping blocks 2 to move toward the relative inner sides, thereby increasing the clamping force on the wiring harness. After adjusting to the appropriate position, the force applied to the handle is released. At this time, gear 2 16 stops rotating under the engagement of the clamping block 19, so that gear 2 16 limits and fixes the pull rod 12, thereby fixing the position of the clamping block 2. When reducing the clamping force, it is only necessary to twist the twist handle to separate the clamping block 19 from gear 2 16, and then pull the pull rod 12 outward to the appropriate position and then release the force on the twist handle to make the clamping block 19 engage with gear 2 16, thereby realizing the limit fixation of the position of the pull rod 12 and completing the reduction of the clamping force. It is easy to use and more practical.
