[0020] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0021] Reference Figure 1 , Figure 2 and Figure 3 As shown, the utility model provides a technical solution: a traction structure of a road tow truck, comprising a road tow truck body 1, a shelf 2 is installed on the top of the road tow truck body 1, both ends of the shelf 2 are fixedly connected with round rods 3, the surface of the round rod 3 is slidably connected with a connecting plate 4, one side of the connecting plate 4 is fixedly connected with a fixing rod 5, the surface of the fixing rod 5 is slidably connected with a hollow rod 6, the inner wall of the hollow rod 6 is fixedly connected with a traction frame 7, one side of the traction frame 7 is fixedly connected with a connector 8, a card slot 9 is provided at one end of the connecting plate 4, two square slots 10 are provided on the top of the shelf 2, a baffle 11 is installed inside the square slot 10, a first through-slot 12 is provided on the top of the baffle 11, a second through-slot 13 is provided at one end of the inner cavity of the square slot 10, a card block 14 is slidably connected inside the second through-slot 13, and one end of the card block 14 is fixedly connected A first arc block 15 is connected, one end of the first arc block 15 is fixedly connected to an ejection spring 16, one end of the ejection spring 16 is fixedly connected to the inner wall of the square slot 10, a connecting rod 17 is slidably connected to the inside of the first through-slot 12, a second arc block 18 is fixedly connected to the bottom of the connecting rod 17, and a handle 19 is fixedly connected to the top of the connecting rod 17. The staff rotates the connecting plate 4 to make the connecting plate 4 drive the traction frame 7 to rotate downward, so that the traction frame 7 rotates to the bottom of the shelf 2, and then drives the second arc block 18 at the bottom by pushing the connecting rod 17 downward, so that the second arc block 18 abuts against the first arc block 15, so that the first arc block 15 drives the card block 14 to be inserted into the card slot 9 to fix and store the traction frame 7, thereby avoiding collision or scratching with other objects during driving, reducing vehicle damage and accident risks.
[0022] Reference Figure 3As shown, in this embodiment: the top of the second arc block 18 is fixedly connected with a thrust spring 20, and the top of the thrust spring 20 is fixedly connected to the bottom of the baffle 11. By setting the thrust spring 20, when the staff pushes the second arc block 18 downward, the thrust spring 20 will generate a downward force, so that the second arc block 18 is more stable when abutting against the first arc block 15, and will not shake due to external force, resulting in unstable fixation.
[0023] Reference Figure 3 As shown, in this embodiment: both ends of the inner cavity of the square groove 10 are provided with sliding grooves 21, and both ends of the second arc block 18 are fixedly connected with sliders 22. Through the coordinated use of the sliding grooves 21 and the sliders 22, the trajectory of the second arc block 18 when moving downward is more stable, and there will be no swinging, which will cause the second arc block 18 to be unable to push the first arc block 15.
[0024] Reference Figure 1 and Figure 4 As shown, in the present embodiment: a telescopic groove 23 is provided at one end of the fixed rod 5, a telescopic rod 24 is fixedly connected inside the telescopic groove 23, a pressing block 25 is fixedly connected at one end of the telescopic rod 24, and a plurality of notches 26 are provided at one end of the hollow rod 6. The staff moves the pressing block 25 so that the pressing block 25 drives the telescopic rod 24 to retract into the telescopic groove 23, and then moves the fixed rod 5 so that the fixed rod 5 slides inside the hollow rod 6, so that the length of the traction frame 7 can be extended, and it can be adjusted to the most suitable traction position and angle according to the size and position of different faulty vehicles, which enables the road tow truck body 1 to cope with more types of faulty vehicles and improves adaptability and flexibility.
[0025] Reference Figure 4 As shown, in the present embodiment: one end of the push block 25 is fixedly connected to a return spring 27, and one end of the return spring 27 is fixedly connected to the inside of the telescopic slot 23. When the staff presses the push block 25, the return spring 27 will start to accumulate force. When the staff releases the push block 25, the return spring 27 will drive the push block 25 to rebound into the slot 26 through its own elastic force, so that the staff can fix it more quickly.
[0026] Reference Figure 5 As shown, in this implementation scheme: the top and bottom of the inner cavity of the hollow rod 6 are provided with limiting grooves 28, and the top and bottom of the fixed rod 5 are fixedly connected to the limiting blocks 29. By setting the limiting grooves 28 and the limiting blocks 29, when the staff moves the fixed rod 5 to slide on the hollow rod 6, the limiting blocks 29 will abut against the limiting grooves 28 to prevent the fixed rod 5 from being pulled out too much and falling off.
[0027] Working principle: the staff rotates the connecting plate 4 so that the connecting plate 4 drives the traction frame 7 to rotate downward, thereby causing the traction frame 7 to rotate to the bottom of the shelf 2, and then drives the second arc block 18 at the bottom by pushing the connecting rod 17 downward, so that the second arc block 18 abuts against the first arc block 15, so that the first arc block 15 drives the card block 14 to be inserted into the card slot 9 to fix and store the traction frame 7, thereby avoiding collision or scratching with other objects during driving, reducing vehicle damage and accident risks, and by setting a thrust spring 20, when the staff pushes the second arc block 18 downward, the thrust spring 20 will generate a downward force, so that the second arc block 18 is more stable when abutting against the first arc block 15, and will not shake due to external force, resulting in unstable fixation. Through the coordinated use of the slide groove 21 and the slider 22, the trajectory of the second arc block 18 when moving downward is more stable, and there will be no swinging, which will cause the second arc block 18 to be unable to push In the case of the first arc block 15, the staff moves the push block 25 so that the push block 25 drives the telescopic rod 24 to retract into the telescopic groove 23, and then moves the fixed rod 5 so that the fixed rod 5 slides inside the hollow rod 6, so that the length of the traction frame 7 can be extended, and it can be adjusted to the most suitable traction position and angle according to the size and position of different faulty vehicles, which enables the road tow truck body 1 to cope with more types of faulty vehicles and improves adaptability and flexibility. When the staff presses the push block 25, the return spring 27 will start to accumulate force. When the staff releases the push block 25, the return spring 27 will drive the push block 25 to rebound into the slot 26 through its own elastic force, so that the staff can fix it more quickly. By setting the limit groove 28 and the limit block 29, when the staff moves the fixed rod 5 to slide on the hollow rod 6, the limit block 29 will abut against the limit groove 28 to prevent the fixed rod 5 from being pulled out too much and falling off.
