[0024] Combined with appendix Figures 1 to 9 As shown, this embodiment discloses a linkage-type container locking device. This linkage-type container locking device is installed inside the corner posts 8 of the container. Each of the four corner posts 8 of the container has one linkage-type container locking device, including an upper screw 1, a fixing plate 4, a middle sleeve post 2, a rotating lock head 3, a guide plate 5, a large spring 6, and a small spring 7. The fixing plate 4 is located above the middle sleeve post 2 and has a through hole. The upper screw 1 passes through the through hole and is threaded to the upper part of the middle sleeve post 2. The thread of the upper screw 1 is a relatively coarse thread. The guide plate 5 and the rotating lock head 3 are located below the middle sleeve post 2. The lower end of the middle sleeve post 2 is connected to the guide plate 5 via the large spring 6. The guide plate 5 has a hole, and the hole wall has a second oblique guide groove with sparse texture and a large inclination angle. The rotating lock head 3 has a corresponding first oblique guide groove 34 with sparse texture and a large inclination angle. The first oblique guide groove 34 and the second oblique guide groove cooperate with each other. When the intermediate sleeve column 2 presses down to rotate the locking head 3, the locking head 3 will rotate under the guidance of the first oblique guide groove 34 and the second oblique guide groove.

[0025] The length of the intermediate sleeve post 2 is about half the length of the container corner post, the length of the upper screw 1 is about one-third the length of the container corner post, the length of the rotating lock head 3 is about one-quarter the length of the container corner post, and most of the upper screw 1 is screwed into the screw hole of the intermediate sleeve post 2.

[0026] The upper screw 1 includes a screw head 11 and a screw rod 12. The upper end of the screw rod 12 is fixedly connected to the screw head 11. The screw rod 12 is screwed into the screw hole 21 with continuous threads on the upper part of the intermediate sleeve column 2. The screw head 11 is provided with a groove 13, which cooperates with the protrusion of the turnlock below the container spreader.

[0027] The fixing plate 4 is fixed to the inner wall of the corner post 8 to prevent the upper screw 1 from moving downward. The guide plate 5 is set inside the corner post 8 and can move up and down inside the corner post 8.

[0028] The intermediate sleeve column 2 is a rectangular column and is located inside the corner column 8, where it can move up and down. The upper part of the intermediate sleeve column 2 is provided with a screw hole 21 with continuous threads, and the lower part is a solid structure 22, which is fixedly connected to the upper end of the large spring 6.

[0029] The rotating lock head 3 includes a pressure block 31, a rotating rod 32, and a lock head 33. The upper end of the rotating rod 32 is fixedly connected to the pressure block 31, and the lower end of the rotating rod 32 is fixedly connected to the lock head 33. The rotating rod 32 is provided with a first oblique guide pattern that matches the second oblique guide pattern. The lock head 33 is elliptical in shape, and elliptical through holes 81 are provided at both ends of the corner post 8. The shape of the lock head 33 is the same as that of the turnlock below the container spreader, and the initial direction of the lock head 33 is consistent with the direction of the elliptical through holes 81 of the corner post 8.

[0030] A small spring 7 is connected between the upper surface of the guide plate 5 and the lower end of the pressure block 31. The small spring 7 is sleeved on the upper part of the rotating rod 32. The small spring 7 is used to keep the guide plate 5 at a certain distance from the rotating lock head 3 below, and also serves to restore the rotating lock head 3 to its original position after the container is unlocked.

[0031] When lifting a container, the elliptical turnlock of the container spreader first extends into the elliptical through hole 81 at the upper end of the corner post 8, and then rotates 90 degrees so that the turnlock of the spreader is in a 90-degree vertical locking state with the elliptical through hole 81 above the corner post of the container. At the same time, the protrusion on the turnlock is engaged with the groove 13 of the upper screw 1. Then the container is lifted and placed on top of another container.

[0032] The locking process of the two containers is as follows: The container spreader rotates 90 degrees clockwise. At this time, the elliptical lock of the spreader is parallel to the elliptical through hole 81 at the upper end of the corner post, realizing the release of the spreader and the upper corner post of the container. At the same time, since the lower lock of the spreader is connected to the screw head of the upper screw 1 of this locking device, the spreader drives the upper screw 1 to rotate 90 degrees clockwise. Since the fixing plate 4 is below the screw head 11 of the upper screw 1, the upper screw 1 cannot move downward and can only rotate 90 degrees in place. Since the outer part of the intermediate sleeve column 2 is a cuboid and cannot be rotated, when the upper screw 1 rotates, the relative positions of the two will be moved. The position of the upper screw 1 remains unchanged, and the intermediate sleeve column 2 moves downward a certain distance under the action of the thread. The intermediate sleeve column 2 is connected to the guide plate 5 through the large spring 7. The guide plate 5 and the rotating lock head 3 are connected through the first oblique guide groove and the second oblique guide groove. The downward movement of the intermediate sleeve column 2 drives the guide plate 5 and the rotating lock head 3 to move downward. The rotating lock head 33 passes downwards through the lower hole of the corner post of this container and the upper hole of the corner post of the lower container, entering the upper corner post of the lower container until the guide plate 5 touches the bottom of the corner post. At this point, the guide plate 5 and the rotating lock head 3 can no longer move downwards, while the intermediate sleeve post 2 continues to move downwards, causing the solid structure at the bottom of the intermediate sleeve post 2 to contact the pressure block 31 of the rotating lock head 3. The intermediate sleeve post 2 continues to move downwards, applying a certain pressure to the rotating lock head 3. The guide plate 5 and the rotating lock head 3 are connected by the first oblique guide groove 34 and the second oblique guide groove. Under the guidance of the first oblique guide groove 34 and the second oblique guide groove, the rotating lock head 3 is pressed and rotates, thereby locking with the lower container. Because the intermediate sleeve post 2 is relatively heavy, the small spring 7 cannot drive the lower rotating lock head 3 to bounce upwards, preventing the small spring 7 from being compressed and causing the rotating lock head 3 to rotate and unlock itself.

[0033] The unlocking process between the two containers is as follows: The container spreader extends into the elliptical through-hole 8 above the corner post and rotates 90 degrees counterclockwise. The upper screw 1 rotates 90 degrees counterclockwise, causing the middle sleeve post 2, the large spring 6, and the guide plate 5 to move upward. When the guide plate 5 moves upward, under the guidance of the first oblique guide groove 34 and the second oblique guide groove, the rotating lock head 3 will rotate 90 degrees in the opposite direction, realizing the rotational unlocking. During the upward movement of the middle sleeve post 2, the pressure on the small spring 7 gradually decreases, causing the rotating lock head 3 below to spring upward after unlocking. At this time, the spreader's rotary lock is in a 90-degree vertical locking state with the elliptical through-hole 81 above the container corner post, and the spreader can lift the container.

[0034] This utility model can lock and fix containers using a container spreader to prevent them from moving or tipping over. Locking and unlocking of containers can be done manually, reducing labor costs, minimizing the risks of manual operation, and improving work efficiency. The locked containers are also highly stable and effective.

[0035] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
