The above-mentioned scheme solves the problem in the prior art that the manual operation and fixing by workers is inefficient and inconvenient to check whether the container is locked.

[0023] According to this specific embodiment, the partition 104 is arranged inside the box body 101 and fixedly connected to the box body 101, the partition 104 has a rectangular groove 105, the two groups of the clamping components are symmetrically arranged in the rectangular groove 105, the clamping plate 108 is arranged on the upper surface of the partition 104, one end of the movable plate 109 is fixedly connected to the clamping plate 108, the other end of the movable plate 109 passes through the rectangular groove 105, the guide member is arranged on one side of the clamping plate 108, the bidirectional threaded rod 103 respectively passes through the two movable plates 109, and is threadedly matched with the two movable plates 109, the two ends of the bidirectional threaded rod 103 are respectively rotatably connected to the box body 101, the motor 102 is fixedly connected to the outside of the box body 101, the output end of the motor 102 is fixedly connected to one end of the bidirectional threaded rod 103, and the two mounting plates 106 are respectively connected to The box body 101 is fixedly connected and located on the outside of the box body 101, the two ends of the warning light 107 are respectively fixedly connected to the two mounting plates 106, the sensing component is arranged inside the box body 101, and the fixing component is arranged above the box body 101. When it is used specifically, the box body 101 is fixed to the semi-trailer, the fixing component is fixed to the container, and then the container is hoisted onto the semi-trailer, and the fixing component is inserted into the box body 101. When the fixing component matches the box body 101, the sensing component controls the warning light 107 to light up, and then the motor 102 is started. The motor 102 drives the bidirectional threaded rod 103 to rotate, so that the two movable plates 109 move relative to each other, and the two movable plates 109 respectively drive the corresponding clamping plates 108 to move, thereby fixing the fixing component, so that the container and the semi-trailer are fixed.

[0024] Among them, one end of the guide rod 110 is fixedly connected to the clamping plate 108, and the other end of the guide rod 110 passes through the box body 101 and is fixedly connected to the limit block 111.

[0028] When the automatic locking mechanism for a container of a heavy truck semi-trailer of the present embodiment is used, the box body 101 is fixed to the semi-trailer, the connecting plate 112 is fixed to the container, and then the container is hoisted onto the semi-trailer, and the abutting plate 113 is inserted into the box body 101. When the connecting plate 112 drives the abutting plate 113 to be inserted into the box body 101, the connecting plate 112 abuts against the disc 116 to move downward, the spring 118 contracts, and the disc 116 drives the round rod 117 to move downward, so that the round rod 117 contacts with the controller 115, and the controller 115 controls the warning light 107 to light up, and then starts the motor 102, and the motor 102 drives the bidirectional threaded rod 103 to rotate, so that the two movable plates 109 move relative to each other, and the two movable plates 109 respectively drive the corresponding clamping plates 108 to move, thereby fixing the abutting plate 113, so that the container and the semi-trailer are fixed. This method can effectively solve the problem in the prior art that the worker manually operates and fixes, which is inefficient and inconvenient to check whether the container is locked.
