DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] It should be noted that the driving cylinder 1 is fixedly mounted on the tow truck and can be controlled and powered by it, and these are all existing public technologies, so no further details will be given.

[0030] In this embodiment, the tire holding assembly 300 is a structure for holding a vehicle tire conveniently and stably.

[0031] like Figure 1 、 Figure 2 and Figure 3As shown, each tire holding assembly 300 includes a sleeve steel cylinder 301 slidably connected to one end of the connecting rod 202, two limit fork plates 302 fixed on the sleeve steel cylinder 301 and spaced apart along the length direction of the connecting rod 202, and an inclined block 303 fixed between the opposite sides of the two limit fork plates 302. Each limit fork plate 302 is provided with a plurality of limit holes 305 spaced apart along the length direction of the limit fork plate 302. Each tire holding assembly 300 also includes a limit rod 306, which is detachably plugged into the two limit fork plates 30 2, a limiting rod 306 is arranged parallel to and spaced from the inclined surface block 303. A first rope threading hole 307 is provided at each end of the limiting rod 306. Each limiting fork plate 302 is provided with a plurality of second rope threading holes 308 spaced along its length. The second rope threading holes 308 are closer to the sleeve 301 than the first rope threading holes 307. The lashing rope 4 can pass through the two first rope threading holes 307 and at least one second rope threading hole 308 on each limiting fork plate 302 and be fastened to the tire of the towed vehicle. The spacing between the two sleeves 301 can be adjusted by sliding the sleeve 301 to accommodate different wheelbases. After the two limiting fork plates 302 are positioned on either side of the tire by driving the oil cylinder 1 and the tire rests on the inclined surface block 303, the limiting rod 306 is installed, causing the tire to be clamped between the inclined surface block 303, the limiting rod 306, and the two limiting fork plates 302. At the same time, by selectively inserting the limiting rod 306 into the corresponding two different limiting holes 305, the limiting rod 306 is positioned differently between the two limiting fork plates 302, that is, the distance between the limiting rod 306 and the inclined block 303 is different, thereby accommodating tires of different specifications. Finally, the tie rope 4 is passed through the first rope threading hole 307 and the second rope threading hole 308 to secure the limiting rod 306, thereby securing the tire to the tire by the tire holding assembly 300.

[0032] It should be noted that the opposite sides of the two steel cylinders 301 are both open, so that the steel cylinders 301 can slide normally on the outer periphery of the connecting rod 202. The connecting piece 201 is U-shaped, and the side away from the driving cylinder 1 is open, so that the connecting rod 202 can be normally hinged on the inner side of the connecting piece 201. The strap rope 4 is passed between the inner sides of several first rope threading holes 307 and second rope threading holes 308 on the same steel cylinder 301, and is bound to the outer side of the wheel axle to facilitate the stable connection between the tire and the tire holding assembly 300.

[0033] In addition, the contact surface between the ramp block 303 and the tire of the vehicle being towed is an inclined surface, which is tilted downward away from the steel sleeve 301, thereby improving the stability of the tire fixation. Furthermore, the contact surface between the ramp block 303 and the tire of the vehicle being towed is provided with irregular tread grooves, which increases friction and further improves the stability of the tire fixation.

[0034] Preferably, a weight-reducing hole is opened on the inclined plane block 303 to reduce the weight of the tire holding assembly 300 .

[0035] In this embodiment, a reduction groove 304 is formed on the limit fork plate 302, and the limit hole 305 is formed on the wall or bottom of the reduction groove 304. The reduction groove 304 can appropriately reduce the weight of the limit fork plate 302 and improve the appearance.

[0036] Each tire-holding assembly 300 further includes an adjustment pin 310. A pin hole 309 is defined in the steel sleeve 301. Specifically, two opposing pin holes 309 are defined on opposite walls of the steel sleeve 301. The adjustment pin 310 passes through the pin holes 309 and optionally through one of the adjustment holes 203. After the steel sleeve 301 is placed on the connecting rod 202, the steel sleeve 301 is moved so that the two opposing pin holes 309 on the steel sleeve 301 align with one of the adjustment holes 203, depending on the tire specifications. The adjustment pin 310 is then inserted, fixing the relative position of the steel sleeve 301 and the connecting rod 202.

[0037] Specifically, each tire holding assembly 300 also includes a bolt 312 and a nut 313. Two symmetrical plates 311 are provided on one side of the steel sleeve 301, spaced apart and facing each other. A latch hole 309 is located between the two symmetrical plates 311. Each symmetrical plate 311 has a first connection hole, and the adjustment pin 310 has a second connection hole. The bolt 312 passes through one first connection hole, the second connection hole, and another first connection hole, and then is threadedly connected to the nut 313. After passing through the latch holes 309 and the adjustment hole 203, one end of the adjustment pin 310 extends from one of the latch holes 309. At this point, the bolt 312 is inserted, passing through the two first and second connection holes, thereby securely connecting the adjustment pin 310 to the two symmetrical plates 311 and ensuring the stability of the connection between the steel sleeve 301 and the connecting rod 202. It should be noted that the axial cross-section of the adjusting pin 310 can be T-shaped or straight, that is, the adjusting pin 310 can be a T-shaped pin or a straight rod pin. When the adjusting pin 310 is a T-shaped pin, the end without the second connecting hole is a T-shaped head, and the T-shaped head abuts against one side of the sleeve steel cylinder 301 to prevent it from falling off from the first pin hole 309; when the adjusting pin 310 is a straight rod pin, second connecting holes are provided at both ends of the adjusting pin 310, and two symmetrical plates 311 are provided on each side wall of the outer walls on the opposite sides of the sleeve steel cylinder 301, and two bolts and nuts are also provided to fix both ends of the adjusting pin 310 to prevent the adjusting pin 310 from falling off.

[0038] The working principle of the above embodiment is:

[0039] When clearing obstacles for cars on the road, the positions of the two steel cylinders 301 are adjusted according to the wheelbase, so that the steel cylinder 301 moves on the connecting rod 202 along the length direction of the connecting rod 202. The movement of the steel cylinder 301 can be completed by inserting the adjusting pin 310 between the corresponding pin hole 309 and the adjusting hole 203, passing it through the bolt 312, and finally locking it with the nut 313. The tow truck is controlled to drive the oil cylinder 1 to start, so that the connecting piece 201 drives the connecting rod 202 to move, so that the corresponding two limit fork plates 302 are moved respectively. Move to the outside of the two front wheels, so that the outside of the front wheels of the car fit into the inclined surface of the inclined block 303. According to the actual tire diameter, the limiting rod 306 is passed between the corresponding two limiting holes 305 to complete the limiting work on the side of the tire away from the inclined block 303. At this time, the tire will be limited between the corresponding inclined block 303 and the opposite side of the limiting rod 306. The strap rope 4 is passed through the first rope threading hole 307 and the second rope threading hole 308 and tied to the outside of the wheel axle to complete the further positioning of the tire. The tow truck can be controlled to start and lift the front wheels of the car to facilitate the movement of the car.

[0040] Compared with the existing technology, the tire holding mechanism of the tow truck can more conveniently move the tire holding mechanism to the bottom of the tire to perform the tire holding task by driving the oil cylinder 1, the connecting piece 201, the connecting rod 202, the tire holding assembly 300 and the binding rope 4, so that the tire holding work can be carried out more easily and efficiently. It can not only be adjusted according to the wheelbase, but also be more appropriately adapted and adjusted according to the diameter of the tire, thereby further improving the adaptability to the tire and the car, and allowing the tire to be more stably held and limited, thereby effectively improving the practicality of the tire holding mechanism of the tow truck, and solving the problem that the existing tow truck wheel holding mechanism requires a lot of structural disassembly and assembly during actual use, which is not convenient for efficient tire holding work.
