[0024] Refer to Figure 1 - Figure 2 , an embodiment provided by the present invention: a locking mechanism for a container spreader, including a working box 1 and a clamping plate 11.

A fixing component is arranged on the upper surface of the working box 1, and the fixing component is used to facilitate being lifted by a crane; the fixing component includes a hanging bracket 2, the lower surface of the hanging bracket 2 is fixedly connected to the upper surface of the working box 1, and a suspension ring 3 is fixedly connected to the upper surface of the hanging bracket 2;
[0025] Specifically, the hydraulic cylinder 13 drives the fixed plate 14 to move leftward, drives the rotating plate 15 to move leftward. At the same time, under the limitation of the outer wall of the moving plate 16, it drives the moving plate 16 to rotate rightward. At the same time, the pushing plate 17 is driven to rotate rightward through the fixed plate 14. The first fixing rod 18 fixed to the inner wall of the pushing plate 17 drives the connecting plate 19 to move forward. Under the action of the second fixing rod 20, the connecting plate 19 rotates forward, drives the moving plate 16 to move forward, and has an effect of releasing the container. The hanging bracket 2 and the suspension ring 3 have an effect of facilitating the lifting of the entire spreader.
[0026] Refer to Figure 3, a motor 4 is fixedly connected to the upper surface of the working box 1, and the output end of the motor 4 is fixedly connected to a gear 5; a rack 6 is meshed with the outer wall of the gear 5, and a protective plate 7 is fixedly connected to the outer wall of the rack 6; a sliding plate 8 is fixedly connected to the lower surface of the protective plate 7, and the upper surface of the protective plate 7 is slidably connected to the inner wall of the working box 1; the outer wall of the sliding plate 8 is slidably connected to the inner wall of the working box 1, and the lower surface of the sliding plate 8 is fixedly connected to the upper surface of the clamping plate 11;
[0027] Specifically, the motor 4 drives the gear 5 to rotate to the right, drives the rack 6 and the protective plate 7 to move to the right, drives the sliding plate 8 to move to the right through the protective plate 7, and drives the clamping plate 11 to move to the right through the sliding plate 8, achieving the effect of adjusting the distance. The inner wall of the working box 1 restricts the range of the rightward movement of the sliding plate 8.
[0028] Refer to Figure 3 , a sliding seat 9 is fixedly connected to the lower surface of the sliding plate 8, and the lower surface of the sliding seat 9 is slidably connected to the inner wall of the working box 1; a slide rail 10 is slidably connected to the inner wall of the sliding seat 9, and the lower surface of the slide rail 10 is fixedly connected to the inner wall of the working box 1;
[0029] Specifically, the inner wall of the sliding seat 9 is driven by the protective plate 7 to slide to the right on the outer wall of the slide rail 10, and the slide rail 10 restricts the rightward sliding of the sliding seat 9.
[0030] Working principle: When using this spreader, the hydraulic cylinder 13 drives the fixed plate 14 to move rightward, driving the rotating plate 15 to move rightward. Under the limit of the outer wall of the moving plate 16, the moving plate 16 is driven to rotate leftward. At the same time, due to the rightward movement of the fixed plate 14, the push plate 17 is driven to rotate leftward. The first fixed rod 18 fixed to the inner wall of the push plate 17 drives the connecting plate 19 to move backward. Under the action of the fixed block 21 and the second fixed rod 20, the connecting plate 19 rotates backward. The right inner wall of the connecting plate 19 rotates on the outer wall of the moving plate 16, driving the moving plate 16 to move backward, achieving the locking effect on the container, reducing the manual operation steps and time, improving the operation efficiency and the safety of workers. The hydraulic cylinder 13 can expand the movement range through the rotating shaft 12, enabling the hydraulic cylinder 13 to rotate. The motor 4 fixed on the upper surface of the working box 1 drives the gear 5 to rotate leftward, driving the toothed rod 6 and the protective plate 7 to move leftward. The protective plate 7 drives the sliding seat 9 to slide leftward on the outer wall of the slide rail 10. The slide rail 10 has an effect of restricting the leftward sliding of the sliding seat 9 from deviating. The sliding plate 8 drives the clamping plate 11 to move leftward. Under the action of the gear 5, while further fixing the container, it achieves the effect of adapting to containers of different sizes. The protective plate 7 plays a role in protecting the toothed rod 6. During the use of this spreader, not only does it achieve the locking of the container, ensure the stability of the container during transportation, and improve its safety, but also it can adjust the spacing, enabling the spreader to effectively fix containers of different sizes and shapes, thereby improving the flexibility and applicability of the spreader.
[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
