[0015] A driving member is drivingly connected to the other end of the ejector pin and is used to drive the ejector pin to slide along its own axial direction. When the ejector pin slides along its own axial direction, the ejector pin drives the turntable to rotate through the second connecting rod.

[0016] As a further improvement and optimization of this solution, the driving member is a hydraulic cylinder installed on the feed door.

[0017] As a further improvement and optimization of this solution, the first connecting rod and the second connecting rod are distributed in sequence along the circumference of the turntable.

[0018] As a further improvement and optimization of the present solution, the axial direction of the turntable is perpendicular to each of the locking pins / the ejector pins.

[0019] As a further improvement and optimization of this solution, the outer parts of the ejector pin and the three locking pins are sleeved with a pin tube, the pin tube is arranged on the feed door, and the ejector pin / the locking pin can slide axially compared to the pin tube.

[0020] Compared with the prior art, the above technical solution has the following positive effects:

[0021] (1) In the present invention, three sets of locking components are provided to respectively lock the three sides of the feed door, thereby improving the reliability of the locking and ensuring that the seal is tight and reliable when the container is closed.

[0022] (2) In the utility model, the three locking pins are driven to slide axially at the same time by the rotation of the turntable, so that the three locking pins are respectively extended into or disengaged from the pin holes on the corresponding pin seats, thereby realizing the locking or unlocking operation of the feed door, reducing the number of operating mechanisms, and reducing the weight and production cost of the locking mechanism.

The driving member is in transmission connection with the other end of the top pin 7 and is used to drive the top pin 7 to slide along its own axis. When the top pin 7 slides along its own axis, the top pin 7 drives the turntable 4 to rotate through the second connecting rod 6.

[0035] Further, as a preferred embodiment, the driving member is a hydraulic cylinder mounted on the feed door 3. Through the cooperative movement of an oil cylinder and the turntable 4, three-point locking of the feed door 3 of the container 1 can be achieved, improving the sealing requirements and reducing the cost at the same time.

[0036] In another embodiment, the driving member can also be a cylinder, an electric cylinder, etc.

[0037] Further, as a preferred embodiment, the three first link rods 51 and the second link rod 6 are sequentially distributed along the circumferential direction of the turntable 4.
