DETAILED DESCRIPTION
[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0024] Example:
[0025] See also Figure 1-Figure 5 , the utility model provides a technical solution:
[0026] A multi-angle traction device for transporting large items, comprising a front fixing seat 1, a traction hook 2 is installed on the left side of the front fixing seat 1, a frame 3 is installed outside the traction hook 2, a support rod 4 is installed on the side of the frame 3 away from the traction hook 2, a trailer fixing seat 5 is installed on the side of the support rod 4 away from the frame 3, and a locking assembly 6 is installed on the top of the frame 3;
[0027] The locking assembly 6 is used for quickly connecting the towing hook 2 and the frame 3 .
[0028] For further information, see Figure 1 , Figure 3 and Figure 4In this embodiment, the locking assembly 6 includes an outer frame 601, a locking rod 602, a bifurcated rod 603, a swing rod 604, a connecting shaft 605 and a handle 606. The outer frame 601 is installed on the top of the frame 3, the locking rod 602 is installed inside the outer frame 601, the bifurcated rod 603 is installed on the top of the outer side of the locking rod 602, the swing rod 604 is installed on the bottom of the outer side of the locking rod 602, the connecting shaft 605 is installed inside the bifurcated rod 603, and the handle 606 is installed on the side of the connecting shaft 605 away from the bifurcated rod 603. When large items need to be transported, the large items are placed on the trailer, the trailer fixing seat 5 is installed to one end of the trailer, and the front fixing seat 1 is installed to one end of the front of the vehicle. The operator controls the front of the vehicle to approach the frame 3, so that the towing hook 2 is inserted into the interior of the frame 3, so that the towing hook 2 squeezes the swing rod 604, so that the swing rod 604 releases the locking rod 602, and the locking rod 602 slides down and falls into the interior of the towing hook 2, thereby realizing the connection between the front of the vehicle and the trailer.
[0029] Among them, see Figure 1 , Figure 3 and Figure 4 In this embodiment, a fixing column 607 is installed at the top of the locking rod 602 at a position corresponding to the forked rod 603, a groove is opened at the bottom end of the locking rod 602, and a clamping column 608 is installed at a position corresponding to the groove on the outside of the swing rod 604. When the transportation is completed and the connection between the vehicle head and the trailer needs to be released, the handle 606 is turned to rotate the forked rod 603, and then the fixing column 607 is lifted by the forked rod 603, so that the locking rod 602 is raised, and at the same time the swing rod 604 is reset to the initial position, and the clamping column 608 is stuck in the inside of the groove to prevent the locking rod 602 from sliding down. Through this operation, it is easier and more labor-saving to release the connection between the vehicle head and the trailer.
[0030] Second, see Figure 1 and Figure 3 In this embodiment, the outer frame 601 and the interior of the frame 3 are interconnected, the swing rod 604 extends to the interior of the frame 3, and a square groove 301 is provided at the bottom end of the inner side of the frame 3. The square groove 301 realizes a hollow state between the frame 3 and the outer frame 601, which facilitates the locking rod 602 to descend and connect with the towing hook 2.
[0031] Furthermore, please see Figure 2 In this embodiment, a connecting seat 7 is installed at one end of the support rod 4 close to the frame 3, and a connecting rod 701 is installed inside the connecting seat 7. The frame 3 is connected to the support rod 4 through the connecting rod 701. When the front of the vehicle turns, the connecting rod 701 is driven to rotate inside the connecting seat 7 at the same time, so that the front fixing seat 1 can turn, which is convenient for angle adjustment during transportation.
[0032] For further information, see Figure 1 and Figure 2 In this embodiment, a rotating seat is installed on one side of the trailer fixing seat 5 close to the support rod 4, and the support rod 4 is connected to the trailer fixing seat 5 through the rotating seat. Fixing parts 8 are installed on the top of the trailer fixing seat 5 and the support rod 4, and a spring 9 is installed between the two fixing parts 8. When transportation is not needed, the support rod 4 can be folded upward inside the rotating seat through the expansion and contraction energy storage of the spring 9, thereby reducing the floor space and greatly enhancing the practicality.
[0033] For further information, see Figure 5 In this embodiment, a lock buckle 201 is installed inside the towing hook 2, a rotating column 101 is installed at the connection between the front fixing seat 1 and the towing hook 2, and bolts are installed on the side of the front fixing seat 1 away from the trailer fixing seat 5. The rotating column 101 is used to adjust the angle of the towing hook 2 inside the frame 3. Through the design of the lock buckle 201 and the towing hook 2, it is tightly wrapped with the locking rod 602.
[0034] In this embodiment, the implementation scenario is specifically as follows: when large items need to be transported, the large items are placed on the trailer, the trailer fixing seat 5 is installed to one end of the trailer, and the front fixing seat 1 is installed to one end of the front of the vehicle. The operator controls the front of the vehicle to approach the frame 3, so that the towing hook 2 is stuck in the inside of the frame 3, so that the towing hook 2 squeezes the swing rod 604, so that the swing rod 604 releases the fixing of the locking rod 602, and the locking rod 602 slides down and falls into the inside of the towing hook 2 to achieve the connection between the front of the vehicle and the trailer. When the transportation is completed, the connection between the front of the vehicle and the trailer needs to be released, the handle 606 is turned to rotate the fork rod 603, and then the fixing column 607 is lifted by the fork rod 603, so that the locking rod 602 rises, and the swing rod 604 is reset to the initial position, and the clamping column 608 is stuck in the inside of the groove to prevent the locking rod 602 from sliding down. Through this operation, it is easier and more labor-saving to release the connection between the front of the vehicle and the trailer.
