Description

Technical field:

[0002] The utility model relates to a foldable traction rod structure with an adjustable angle for towing a vehicle body. Background technology:

[0004] At present, a two-wheel vehicle body is provided with a towing rod at its front end for towing the vehicle body. The towing rod is a straight rigid rod. When the towing hook of the towing vehicle is too high or too low, the trailer and the towing vehicle are easily mismatched, which can easily cause the trailer platform to tilt, thereby affecting the normal operation of the equipment on the trailer or the falling of the goods on the trailer and other emergencies.

[0005] For example, the Chinese patent "Drum-type LED Lighting Vehicle", publication number CN214647877U, includes a support frame, a pair of rotatable moving wheels are arranged at the lower part of the support frame, a generator cover capable of housing a generator is fixed on the upper part of the moving wheels, a support rod is provided on the side of the generator cover, an LED lighting lamp is fixed on the top of the support frame, the LED lighting lamp includes an outer cylinder and an inner cylinder located in the outer cylinder, an LED light board is fixed on the surface of the outer cylinder, the LED light board is evenly arranged on the outer surface of the outer cylinder along the vertical direction, and the bottom of the outer cylinder is provided with a plurality of LED light boards, wherein the LED light boards are arranged on the outer surface of the outer cylinder uniformly along the vertical direction. An annular bottom plate is fixed between the bottom of the inner cylinder and the inner cylinder, and a power source is fixed in the inner cylinder. The power source is connected to the LED light board through a wire that penetrates the inner cylinder and the outer cylinder. Although the patent has a compact structure and can be easily moved and arranged to meet the lighting requirements of the outdoor space in a circumferential direction and can adapt to various working environments; however, the towing rod is fixed. When the towing hook height of the towing vehicle is too high or too low, the trailer and the towing vehicle are prone to mismatch, which can easily cause the trailer platform to tilt, thereby affecting the normal operation of the equipment on the trailer or the falling of the goods on the trailer and other emergencies. Summary of the invention:

[0007] In view of the above-mentioned problems, the purpose of the utility model is to provide a folding traction rod structure with an adjustable angle. The folding traction rod structure with an adjustable angle is reasonably designed and is conducive to improving the flexibility and adaptability of use.

[0008] The utility model discloses a foldable traction rod structure with adjustable angle, which is characterized by comprising a pulling rod for connecting a vehicle body, wherein the pulling rod comprises a fixed section fixedly connected to the vehicle body and a movable section rotatably connected to the end of the fixed section, wherein mutually meshing saw teeth are arranged on contact surfaces where the fixed section and the movable section are rotatably hinged to each other, and bolts for fixing the movable section and the fixed section are arranged at the rotatably hinged position.

[0009] Preferably, a first step platform is provided at the end of the fixed section, a circular platform is provided on the side of the first step platform, a threaded hole is provided in the center of the circular platform, and a second step platform is provided at the end of the movable section, a circular groove is provided on the side of the second step platform for the circular platform to be inserted, and a through hole is provided at the bottom of the circular groove for the bolt to pass through, and the bolt is threadedly connected to the threaded hole after passing through the through hole.

[0010] Preferably, a rotating handle is fixedly provided on the outer end of the bolt, the bolt has a step section, and a gasket is sleeved on the bolt to abut the end surface of the step section and the end surface of the movable section.

[0011] The method for using the folding traction rod structure with adjustable angle of the utility model is as follows: in normal times, the bolts are locked to relatively fix the movable section and the fixed section so that the two form a relatively rigid rod body, and the rod body is either straight or bent; when the relative rotation angle of the movable section and the fixed section needs to be adjusted, the bolts are loosened, the movable section and the fixed section are rotated, and after the relative rotation angle is determined, the bolts are locked, so that the saw teeth on the contact surface of the fixed section and the movable section that are mutually rotatably hinged are clamped, and the bending angle of the fixed section and the movable section is adjusted.

[0012] The advantages of the angle-adjustable folding traction rod structure of the utility model are as follows:

[0013] It has multi-angle positioning capabilities and can achieve precise angle adjustment to adapt to different types of tractors; this design saves space, facilitates transportation, and improves logistics efficiency and convenience; the tooth meshing structure is stable, not easy to deform, and has high-strength load-bearing performance.
