[0023] In the following description, embodiments of the container safety lock of this utility model will be described with reference to the accompanying drawings.

[0024] Figures 1-5 This invention illustrates a container safety lock according to an embodiment of the present invention, comprising a fixed plate 2 fixedly connected to the front side of a container door 1; a fixed shell 4 fixedly connected to the front side of the fixed plate 2; a limiting plate 3 rotatably connected to the inner cavity of the fixed shell 4; a plurality of bolts 12 threadedly connected to the front side of the fixed plate 2; the rear ends of the bolts 12 extending through to the rear side of the fixed plate 2 and threadedly connected to the container door 1; the two limiting plates 3 are tightly fitted to opposite sides; a handwheel 9 is fixedly connected to the front side of the lower limiting plate 3; a limiting protrusion 10 is fixedly connected to the surface of the limiting plate 3; an arc-shaped groove 11 adapted to the limiting protrusion 10 is provided on the surface of the fixed shell 4; through the cooperation of the limiting protrusion 10 and the arc-shaped groove 11, the limiting plate 3 is limited and guided, thereby improving the stability of the limiting plate 3 during rotation; a semi-circular rotating cylinder 5 is fixedly connected to the front side of the limiting plate 3; a semi-circular fixed cylinder 6 is fixedly connected to the front side of the fixed shell 4; and the semi-circular rotating cylinder 5 is rotatably connected to the semi-circular fixed cylinder 6. The inner cavity of the circular fixed cylinder 6 has a fixed tube 7 fixedly connected to the surface of the right semi-circular fixed cylinder 6. A locking assembly 8 is provided inside the fixed tube 7. The locking assembly 8 includes a locking sleeve 81 fixedly connected to the inner cavity of the fixed tube 7. A lock cylinder 82 is rotatably connected to the inner cavity of the locking sleeve 81. A threaded post 83 is fixedly connected to the left end of the lock cylinder 82. A limit pin 84 is threadedly connected to the surface of the threaded post 83. The limit pin 84 is slidably connected to the inner cavity of the locking sleeve 81. The top and bottom of the limit pin 84... Each part is provided with an arc-shaped limiting groove that matches the lock sleeve 81. A semi-circular groove 85 is provided on the right side of the semi-circular rotating cylinder 5. The limiting pin 84 is inserted into the inner cavity of the two semi-circular grooves 85. Through the cooperation of the lock cylinder 82 and the threaded post 83, the limiting pin 84 is pushed forward by the thread. At the same time, under the cooperation of the limiting pin 84 and the semi-circular groove 85, the two semi-circular rotating cylinders 5 are limited and locked, thereby preventing the limiting plate 3 from rotating and the box door 1 is closed and fixed.

[0025] Working principle: When using this utility model, the user closes the container by rotating the door 1, causing the two fixing discs 2 to fit together. Then, the user rotates the handwheel 9, which drives the left-side limiting disc 3 to rotate. Under the squeezing action of the left-side limiting disc 3, both limiting discs 3 rotate simultaneously, causing both limiting discs 3 to rotate 90 degrees and block the front of the door 1, thus sealing the door 1. At this time, the semi-circular slot 85 reaches the right side. The key is inserted into the inner cavity of the lock cylinder 82, and the lock cylinder 82 is rotated. During the rotation of the lock cylinder 82, the threaded column 83 rotates. Due to the pushing action of the threaded column 83, the limiting pin 84 is pushed horizontally, so that the limiting pin 84 is inserted into the inner cavity of the semi-circular slot 85, limiting and locking the two semi-circular rotating cylinders 5. Thus, the two limiting discs 3 and the two semi-circular rotating cylinders 5 are fixed in one position.

[0026] In summary, this container safety lock, through the combined use of the fixing plate 2, the limiting plate 3, and the fixing shell 4, seals the container door 1. At the same time, through the combined use of the fixing tube 7 and the locking assembly 8, it locks and fixes the semi-circular rotating cylinder 5 and the limiting plate 3, thereby achieving the purpose of quick locking and security against theft.
