Description

Technical Field

[0001] The utility model belongs to a vehicle emergency tool, in particular to a trailer device. Background Art

[0002] The towing device is used to tow a vehicle that cannot continue to drive due to a malfunction to a maintenance site for repair. The front and rear vehicles are connected to each other through the towing device, and the front vehicle's drive is used to tow the faulty vehicle to the destination. At present, there are mainly the following types of towing tools: 1. Use a trailer flat belt to tow the faulty vehicle; 2. Use a wire rope to tow the faulty vehicle; 3. Use an "I"-shaped tow bar to tow the faulty vehicle; 4. Use a special rescue trailer to fix the two front wheels of the faulty vehicle to the trailer platform, and the rear wheels are on the ground or all towed above the flatbed to transport the faulty vehicle to the destination. The existing towing devices and technical means have the following disadvantages: When using a flat belt or wire rope to tow the faulty vehicle, if encountering uphill and downhill sections, it is difficult for the rear vehicle to control the speed, and the direction is difficult to control due to the loss of power assistance, which is prone to rear-end collisions and deviation from the road surface, which is not conducive to driving on long and difficult sections. Although hard towing with an "I"-shaped tow bar will not cause the rear vehicle to stall, the tow bar is likely to fold back, and the rear vehicle is likely to deviate from the road and rear-end collision is likely to occur after the tow bar is folded; at the same time, there is still the problem of difficult control of direction; moreover, when the trailer turns, the rear towed vehicle is likely to deviate when turning, and the stability of the towed vehicle in turning is difficult to grasp. Since the existing tow bar does not have a buffering function, the towed vehicle has a forward impact force due to inertia, resulting in a collision with the towing vehicle and damage to the tow bar. Summary of the invention

[0003] In order to overcome the above-mentioned defects of the existing trailer device for towing a faulty vehicle, the utility model proposes an adjustable angle shock-absorbing V-shaped anti-unhooking trailer traction rod, which is composed of a traction assembly, a shock-absorbing assembly and a towing assembly. The traction assembly includes a traction hanger, a traction hanging hole, a traction rod axle pin and a traction rod. The traction assembly is connected to the traction hook of the towing vehicle through the traction hanger; the shock-absorbing assembly includes a shock-absorbing rod, a telescopic slide, a limit pin and a shock-absorbing spring, which can reduce the impact force generated by the front and rear vehicles during the towing process; the towing assembly includes an adjusting threaded rod, an adjusting nut, a hook fixing seat and a U-shaped traction hook. The U-shaped traction hook cooperates with the arc-shaped end of the shock-absorbing rod to tighten and fix the trailer traction rod and the traction hook of the towed vehicle, so as to prevent the trailer traction rod from slipping or the towed vehicle from shifting sideways. The trailer traction rod can be selected to use a V-shaped traction rod composed of double traction rods or a "one" shaped traction rod of a single traction rod according to the layout and setting of the traction hook of the towed vehicle. The application of the trailer tow bar effectively improves the stability and safety of the towing operation of the faulty vehicle.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1As shown in Figures 3 and 4, an adjustable angle shock-absorbing V-shaped anti-unhooking trailer traction rod of the utility model includes a traction assembly, a shock-absorbing assembly and a towing assembly. The traction assembly consists of a concave traction hanger 1, a traction hanging hole 2, a traction rod axle pin 3 and a traction rod 6. The top of the concave traction hanger 1 is provided with a traction hanging hole 2 fixed thereto as a whole, and the traction assembly is connected to the traction hook of the traction vehicle by using the traction hanging hole 2. A traction rod axle hole 17 is provided at the tail end of the traction rod 6, and three axle pin insertion holes 7 that are equidistantly penetrated from top to bottom are correspondingly provided on the concave traction hanger 1. The traction rod 6 is inserted into the concave groove of the concave traction hanger 1, and the traction rod axle pin 3 is used to penetrate the axle pin insertion hole 7 and the traction rod axle hole 17 to connect the concave traction hanger 1 and the traction rod 6 as a whole, and then the fixing pin 5 is inserted into the pin hole 4 to fix the two. Here, the traction rod axle pin 3 not only plays the role of connecting the concave traction hanger 1 and the traction rod 6, but also has another role. When the axle pin socket 7 in the middle of the concave traction hanger 1 is used to fix the single traction rod for traction operation, the traction rod axle pins 3 on both sides can play the role of limit pins, controlling the middle trailer rod within a certain angle, avoiding the distance between the front and rear vehicles being out of control due to the excessive activity angle of the traction rod 6, and preventing the rear vehicle from stalling and colliding with the front vehicle. The V-type trailer traction rod utilizes the principle of point-fixed surface. According to the characteristics of the automatic self-alignment of the rear vehicle's four-wheel positioning, the rear vehicle can automatically turn and move synchronously with the front vehicle, thereby improving the stability of the traction operation.

[0024] like Figure 1 As shown in FIG. 2 , the shock absorbing assembly consists of a shock absorbing rod 8, a telescopic slide 9, a limit pin 10 and a shock absorbing spring 11. The shock absorbing rod 8 is mounted on the front end of the traction rod 6 and can slide freely thereon. The shock absorbing rod 8 is made of metal pipes. A shock absorbing spring 11 is installed at the front end of the shock absorbing rod 8. A telescopic slide 9 is opened on the tube wall of the shock absorbing rod 8. The limit pin 10 passes through the telescopic slide 9 and is fixed on the traction rod 6, which limits the stroke of the shock absorbing rod 8 relative to the traction rod 6 and keeps the relative sliding of the two unaffected. The front end of the shock absorbing rod 8 is processed into an arc-shaped end 16. The shock absorbing assembly can reduce the impact force generated by the front and rear vehicles during the towing process, avoiding damage to the vehicle body or components during the towing operation.

[0025] The towing assembly consists of an adjusting nut 13, a hook fixing seat 14 and a U-shaped towing hook 15. The hook fixing seats 14 are symmetrically fixed on both sides of the shock absorber rod 8, and a hook through hole 12 is opened on the hook fixing seat 14. The tail end of the U-shaped towing hook 15 is provided with an adjusting thread. The tail end of the U-shaped towing hook 15 passes through the hook through hole 12 of the hook fixing seat 14. The telescopic position of the U-shaped towing hook 15 is adjusted by using the adjusting nut 13. The clamp structure formed by the U-shaped towing hook and the arc-shaped end of the shock absorber rod can be adjusted to tightly clamp the towing hook of the towed vehicle, which can prevent the trailer towing rod from slipping or the towed vehicle from shifting sideways.

[0026] Since the number, size, distance and shape of the front towing hooks of various models are not uniform, and the actual road conditions are also different, there is an urgent need for towing tools that can be used for various models under various road conditions. The trailer towing rod can be selected to use a V-shaped towing rod composed of double towing rods, or a "one"-shaped towing rod with a single towing rod, according to the specific number, size, distance and shape of the towing hooks of the towed vehicle, or according to the specific road conditions. Among them: the opening and closing angle of the V-shaped towing rod can be adjusted arbitrarily within 180° according to needs; the telescopic position of the U-shaped towing hook 15 can also be adjusted arbitrarily according to the specific size and shape of the vehicle towing hook to meet the emergency needs of the faulty vehicle.

[0027] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent transformations made using the contents of the present invention's specification and drawings, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.
