DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] As Figure 1 and Figure 2As shown in the figure, this embodiment provides a quick-foldable tail push device for a carrier vehicle. The push device is arranged between the rear end of the carrier vehicle and the vehicle to be pushed, and includes fixed ear plate I 4, fixed ear plate II 8, and fixed ear plate III 9. One ends of the fixed ear plate I 4, fixed ear plate II 8, and fixed ear plate III 9 are arranged in parallel and are connected to the bearing platform cross beam at the rear end by welding. At the same time, an outer housing 5 is provided between the fixed ear plate I 4 and the fixed ear plate II 8. The outer housing 5 is assembled and connected to the fixed ear plate I 4 and the fixed ear plate II 8 by pins. The cross section of the outer housing 5 is a "U" - shaped structure. One end of the outer housing 5 is provided with a square notch, and a fastening rivet 7 is arranged in the square notch.
[0020] The fixed ear plate I 4 and the fixed ear plate II 8 are provided with positioning holes on the same axis, and a limit pin 3 passes through the positioning holes. At the same time, a swivel pin 2 is arranged at one end of the limit pin 3.
[0021] A limit block 1 is arranged on the end face outside the fixed ear plate I 4. There is an extrusion interference between the limit block 1 and the swivel pin 2 in terms of position dimensions, so the swivel pin 2 is used to limit the rotation of the limit pin 3.
[0022] As shown in Figure 3 the figure, the outer housing 5 forms a structure that can rotate around the pin with the fixed ear plate I 4 and the fixed ear plate II 8 through pins, and can rotate freely when the push device is in the unlocked state.
[0023] One side of the outer housing 5 adopts a characteristic end face with an arc - line shape, and the other side has a characteristic end face with a 1 / 4 - arc shape. A semi - circular notch I 10 and a semi - circular notch II 11 are arranged on the 1 / 4 - arc near the fixed ear plate I 4. The notch design is used to cooperate with the limit pin 3 to realize the mutual conversion between the locked and unlocked states, thereby adjusting the position of the outer housing 5.
[0024] At the same time, an embedded top wood 6 is arranged in the groove of the outer housing 5, that is, the embedded top wood 6 is embedded and assembled with the outer housing 5 through the fastening rivet 7.
[0025] Both ends of the limit pin 3 are cylindrical feature bodies, and the middle shaft body of the limit pin 3 is a semi - cylindrical feature body. The semi - cylindrical feature body is complementary to the outer contour dimensions of the semi - circular notch I 10 and the semi - circular notch II 11.
[0026] Furthermore, Figures 4 - 6 describe the process of the push device realizing the conversion between the unlocked and locked states. Specifically, the working principle of the conversion between the open and locked states:
[0027] As shown in Figure 4As shown, the pushing device is in an initial locked state, at which time the semi-cylindrical feature in the middle of the limiting pin 3 is embedded in the semi-circular notch Ⅰ10, and the external shell 5 is in a vertical position and cannot rotate.
[0028] Push the transfer pin 2 through the opening of the limit pin 3 obliquely upward, and then rotate the transfer pin 2 counterclockwise to drive the limit pin 3 to rotate counterclockwise until Figure 5 In the position shown, the semi-cylindrical feature in the middle of the limiting pin 3 is offset from the semi-circular notch Ⅰ10, the outer shell 5 can rotate freely, and the pushing device is in an unlocked state.
[0029] The outer shell 5 is rotated from a vertical position to a horizontal position, the transfer pin 2 is pushed obliquely upward, and the transfer pin 2 is rotated counterclockwise to drive the limit pin 3 to rotate counterclockwise. Figure 6 In the position shown, the semi-cylindrical feature body in the middle of the limiting pin 3 is embedded in the semi-circular notch II11. At this time, the external shell 5 is in a horizontal position and the jacking device is in a locked working state.
[0030] When the carrier is in the transport state, the outer shell 5 of the pushing device is kept vertical; when the carrier is reversed and unloaded and needs to be pushed to adjust the position of the heavy objects, the outer shell 5 of the pushing device is adjusted to a horizontal position for pushing.
[0031] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
