Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Example: Refer to Figures 1 to 4A tilting corner mechanism for a self-unloading container includes a container crossbeam 1 and two corner pieces 2. The container crossbeam 1 is fixedly installed at the bottom of the container. The two corner pieces 2 are located at the left and right ends of the container crossbeam 1, and both corner pieces 2 are hinged to the container crossbeam 1. Both sides of the corner pieces 2 are provided with pin holes 3. Both sides of the container crossbeam 1 are provided with two pin holes 3. The pin holes 3 on the side wall of the container crossbeam 1 correspond to the pin holes 3 on the side wall of the corner pieces 2. The bottom surface of both corner pieces 2 is provided with locking holes 4.

[0026] Two pin auxiliary mechanisms are provided, each including a pin assembly and a limiting assembly. The pin assembly includes a support bracket 5 fixedly connected to the side wall of the container beam 1. A guide rod 6 is fixedly connected between the side wall of the container beam 1 and the inner wall of the support bracket 5. A movable block 7 is slidably sleeved on the guide rod 6. A pin 8 is rotatably connected to the side wall of the movable block 7. A spring 9 is fixedly connected between the side wall of the movable block 7 and the inner wall of the support bracket 5. The limiting assembly includes a through groove 10 on the side wall of the support bracket 5. A limiting block 11 is slidably connected within the through groove 10. The side wall of the limiting block 11 is fixedly connected to the side wall of the movable block 7. A fixed spring 9 is also fixedly connected to the side wall of the support bracket 5. The fixed plate 12 and the support bracket 5 are provided with a limiting rod 13 on the side. The limiting rod 13 is slidably connected to the bottom surface of the fixed plate 12. The top of the limiting rod 13 is fixedly connected to the limiting plate 14. The bottom surface of the limiting plate 14 and the upper surface of the fixed plate 12 are fixedly connected with a second spring 15. Two pin auxiliary mechanisms correspond to two corner pieces 2 respectively. Two pins 8 also correspond to two corner pieces 2 respectively. The upper surface and bottom surface of the limiting block 11 are respectively attached to the inner top surface and inner bottom surface of the through groove 10, so that the moving block 7 and the limiting block 11 are sufficiently stable when moving. The first spring 9 is sleeved on the guide rod 6, and the second spring 15 is sleeved on the limiting rod 13.

[0027] The working principle of this utility model is as follows: When it is necessary to tilt the container, the locking device of the semi-trailer truck in that direction is released according to the tilting direction, and the locking state between the corner piece 2 and the locking hole 4 is released. At the same time, the insertion state between the corner piece 2 and the container beam 1 at the tilting hinge is also released. After completion, it can be rotated around the hinge of the corner piece 2 when the insertion state is released, thereby realizing the tilting. Moreover, this structure can simultaneously meet the function of tilting in both directions and has high practicality.

[0028] When disengaging the corner piece 2 from the container beam 1, the limiting rod 13 is pulled upward by the limiting plate 14 until it moves above the limiting block 11 without obstructing its movement. Then, the moving block 7 is controlled by the limiting block 11 to pull the pin 8 out of the pin hole 3, thus disengaging the connection. When reconnection is required, the principle is similar. The pin 8 is inserted into the pin hole 3 by the limiting block 11 and the moving block 7. Then, the limiting plate 14 is released, and the limiting rod 13 moves downward under the action of the second spring 15 to block the limiting block 11, thereby restricting the movement of the limiting block 11 and the moving block 7. This stabilizes the connection and improves the stability of the pin connection and the overall stability of the mechanism.

[0029] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
