[0027] An automatic locking tow hook device for a wrecker, as shown in Figure 1 and Figure 2 , comprising:
[0028] A main body 10, one end of the main body 10 is provided with a connecting end 11 for connection, the other end of the main body 10 is rotatably connected with a limiting end 12, the connecting end 11 comprises a cylindrical handle and a ring which is integrally formed with the end of the handle, the handle is rotatably connected with the end of the main body 10, the limiting end 12 forms a frame with a U-shaped cross section, a circular hole is formed in the side wall of the limiting end 12, a rotating shaft is arranged in the circular hole, and the rotating shaft is rotatably connected with the end of the main body 10;
[0029] In the present scheme, the connecting end 11 is connected with the cable on the wrecker winch, specifically, the cable passes through the ring of the connecting end 11 and forms a loop, and then the end head is fixed by cooperating with the special crimping pipe. The rotatable connecting end 11 and the limiting end 12 can guarantee that during towing the vehicle, even if the connected steel cable produces a rotating torque due to stress release, the connecting end 11 and the limiting end 12 will not interfere with each other, facilitating the stress release during the contraction of the steel cable, and making the towing of the vehicle safer.
[0030] As shown in Figure 2 , Figure 3 and Figure 4 , the self-locking structure is arranged on the side wall of the main body 10 for limiting the cable. The self-locking structure includes two hooks 20 that are reversely rotatable. The two hooks 20 are rotatably arranged on the two sides of the limiting end 12. The hooks 20 have hook bodies. The bending directions of the hook bodies of the two hooks 20 are reversely arranged. The two hooks 20 jointly form a lock catch for limiting the cable. The hook 20 includes a hook handle and a hook body. The hook body and the hook handle are integrally formed. The hook handle of one of the hooks 20 is rotatably arranged at a position close to the top on one side of the limiting end 12. The hook handle of the other hook 20 is rotatably arranged at a position close to the bottom on one side of the limiting end 12.
[0031] The limiting end 12 is used for the hook connection between the winch and the vehicle. Specifically, the two ends of the steel cable need to form a closed loop. One of the hooks 20 is flipped to an upward position, and the other hook 20 is flipped to a downward position. The loop of the steel cable is placed into the gap of the limiting end 12. The two hooks 20 are oppositely flipped. The hook bodies of the two hooks 20 pass through the loop of the end head of the steel cable. After the steel cable is tensioned, the hook bodies of the two hooks 20 jointly limit the steel cable to achieve self-locking. Even if the included angle between the steel cable and the ground changes during towing, the two flipable hooks 20 can automatically adapt to the angle adjustment of the steel cable to guarantee the self-locking effect of the two hooks 20 on the steel cable.
[0032] As shown in Figure 5 , the self-locking structure further includes a first anti-dropping column 21 and a second anti-dropping column 22. The first anti-dropping column 21 and the second anti-dropping column 22 are fixedly connected with the limiting end 12. The first anti-dropping column 21 and the second anti-dropping column 22 jointly form a partition for limiting the cable. The first anti-dropping column 21 and the second anti-dropping column 22 are columnar structures. The first anti-dropping column 21 is fixedly installed on the inner bottom surface of the limiting end 12. The second anti-dropping column 22 is fixedly installed on the inner top surface of the limiting end 12. The first anti-dropping column 21 and the second anti-dropping column 22 are parallelly distributed. A channel for cable installation is left between the first anti-dropping column 21 and the second anti-dropping column 22. The first anti-dropping column 21 and the second anti-dropping column 22 are of the same height. The height of the first anti-dropping column 21 is less than the inner height of the limiting end 12. The end portions of the first anti-dropping column 21 and the second anti-dropping column 22 are spaced apart from the inner wall of the limiting end 12.
[0033] As a supplement to the above scheme, in order to extend the use of the above scheme, when the two hooks 20 are not used to lock the loop of the steel cable, the loop of the steel cable can be passed through the passage between the first anti-drop column 21 and the second anti-drop column 22, and then the loop of the steel cable is sequentially passed through the interval formed by the top and bottom surfaces of the limiting end 12 and the end of the first anti-drop column 21 and the second anti-drop column 22. The loop of the steel cable is limited by the partition formed by the first anti-drop column 21 and the second anti-drop column 22, and the self-locking is realized, which has the characteristics of stable and convenient connection, and is more suitable for the demand of quick connection between the winch of the wrecker and the towed vehicle.
[0034] The working principle of the utility model is: the two ends of the steel cable need to form a closed loop, one of the hooks 20 is turned to the upward position, and the other hook 20 is turned to the downward position, the loop of the steel cable is put into the gap of the limiting end 12, and the two hooks 20 are turned to the opposite direction, the hook bodies of the two hooks 20 are all passed through the loop of the end of the steel cable, and the hook bodies of the two hooks 20 limit the steel cable to realize self-locking after the steel cable is tensioned, when the two hooks 20 are not used to lock the loop of the steel cable, the loop of the steel cable can be passed through the passage between the first anti-drop column 21 and the second anti-drop column 22, and then the loop of the steel cable is sequentially passed through the interval formed by the top and bottom surfaces of the limiting end 12 and the end of the first anti-drop column 21 and the second anti-drop column 22. The loop of the steel cable is limited by the partition formed by the first anti-drop column 21 and the second anti-drop column 22, and the limiting and locking of the end of the steel cable are realized.
