The embodiments of this disclosure may be implemented independently of each other, or may be implemented together in an interdependent relationship.

[0025] Reference Figures 1 to 3 This utility model discloses a flatbed trailer with an easily detachable tow frame, including a trailer body 1 and a tow frame 2. The trailer body 1 is a flatbed four-wheeled trailer, including a frame welded from square tubes and a support plate laid on the frame. The frame is equipped with four wheels. The tow frame 2 is a square frame welded from square tubes, with three auxiliary wheels under the frame. The end of the frame is hinged to a tow bracket. The above is the prior art and therefore will not be described in detail. The trailer body 1 is provided with a pin hole and a retractable pin 3 located in the pin hole. The tow frame 2 is provided with a insertion hole 4. One end of the pin 3 can be inserted into the insertion hole 4, while the other end of the pin 3 is still located in the pin hole. Therefore, the pin 3 connects the trailer body 1 and the tow frame 2 together. When towing the tow frame 2, the trailer body 1 can be driven through the connection of the pin 3. The insertion hole 4 can be a circular blind hole, so that after one end of the pin 3 is inserted into the insertion hole 4, it will not leak out of the insertion hole 4.

[0026] As shown in the figure, in the present embodiment, the trailer body 1 is provided with a pin barrel 5, in order to ensure the balance of force, the present application has multiple pin barrels 5 arranged on the trailer body 1, of course, the corresponding multiple plug-in holes 4 are also arranged, the pin hole can be the inner hole of the pin barrel 5, in order to save cost and facilitate manufacturing, the inner hole of the pin barrel 5 is relatively large, and the pin hole is located on the end plate 9 of the pin barrel 5, because the end plate 9 is thick enough, so the length of the pin hole and the contact length with the plug pin 3 can be ensured, the plug pin 3 and the pin barrel 5 are provided with a limiting structure for preventing the plug pin 3 from coming out of the pin barrel 5, the pin barrel 5 is a circular iron barrel, the pin hole is a circular hole, one end of the plug pin 3 can extend out of the opening and be inserted into the plug-in hole 4, in the present embodiment, the plug-in hole 4 can be a circular through hole, because of the limitation of the limiting structure, the plug pin 3 cannot be separated from the pin barrel 5, and only the predetermined length of the plug pin 3 can be extended, so that the plug-in hole 4 is a circular through hole, which will not cause the plug pin 3 to be separated. As a specific structure, the towing frame 2 is provided with a pin sleeve 6, and the plug-in hole 4 is the inner hole of the pin sleeve 6, so that the pin sleeve 6 can be directly cut from a iron pipe, and then welded on the side of the frame, which not only makes the material easy to find, but also simple to process.

[0027] As shown in the figure, the limiting structure includes a handle 7 arranged on the plug pin 3 and a guide hole 8 arranged on the barrel wall of the pin barrel 5, the guide hole 8 can be through with the pin hole, of course, in the present embodiment, it is through with the inner hole of the pin barrel 5, the handle 7 is located in the guide hole 8 and one end passes through the guide hole 8, the other end of the handle 7 is welded with the plug pin 3, the handle 7 can slide along the guide hole 8 to drive the plug pin 3 to move up and down in the pin barrel 5, the guide hole 8 can be a vertical long hole, the two ends of the long hole are closed, so that the handle 7 can only move up and down in the long hole along the long hole, and cannot be pulled out through the long hole. As a preferred structure, the top end of the guide hole 8 is provided with a clamping hole (not shown in the figure), the handle 7 can be clamped into the clamping hole, so that after the trailer body 1 and the towing frame 2 are separated, it can be ensured that the plug pin 3 will not automatically extend out of the pin hole, the clamping hole is partially overlapped with the guide hole 8, the clamping hole is located on one side of the guide hole 8 and slightly inclined downward, so that when the trailer body 1 and the towing frame 2 are separated, the handle 7 can be clamped into the clamping hole, one end of the plug pin 3 will not be in the extended state, avoiding the plug pin 3 from being damaged by colliding with the towing frame 2 when the towing frame 2 is connected with the trailer body 1.

[0028] As a further preferred structure, the guide hole 8 is spirally arranged on the barrel wall of the pin barrel 5, because sometimes the plug pin 3 and the plug-in hole 4 may be too tight due to rust and other reasons, it is difficult to pull out the plug pin 3 directly upward, but if it is rotated, it is easier to pull out the plug pin 3.

[0029] As shown in the figure, the two sides of the pin barrel 5 are oppositely provided with reinforcing rib plates 10, the reinforcing rib plates 10 are fixed with the trailer body 1, because the contact surface of the pin barrel 5 with the trailer body 1 is not large, the welding surface is small, and the pin barrel 5 needs to bear a large tensile force, thus the reinforcing rib plates 10 assist in supporting the pin barrel 5, the rigidity of the pin barrel 5 is improved, and the reliability of the vehicle connection is improved.

[0030] The above has carried on the detailed introduction to the flatbed trailer with the easily disassembled traction frame provided by the embodiment of the utility model, the principle and implementation mode of the utility model are described by applying specific examples in this paper, the above embodiment is only used for helping understanding the method and core idea of the utility model; simultaneously, for the general technical personnel in the field, according to the idea of the utility model, there will be changes in specific implementation mode and application range, and the above is not understood as the limitation of the utility model.
