Description

Technical Field:

[0001] The utility model belongs to the technical field of container installation, and particularly relates to a connection, fixing and locking device for a new type of split-foldable container. Background Art:

[0002] At present, there are large trade gaps among countries around the world. A large number of containers have too high empty container rates during sea and land transportation. Due to the limited space in the transportation vehicle cabins, it is difficult to find a cabin and the transportation cost is too high. In order to reduce the space occupied by containers, improve the utilization rate of cabin space and achieve the effect of energy conservation and emission reduction, manufacturers have designed and produced split-foldable containers to ensure that more than 2 - 4 containers can be stacked in one cabin.

[0003] For the existing split-foldable containers, the following problems exist in their box panel connection and locking devices: Due to the limited space in the split-foldable containers, the lock head can only be rotated to about 45 degrees; in this case, the contact surface between the lock head and the lock hole is too small, and it is very easy for the connection lock device to become unhooked during the vibration of the box body during transportation or when loading and unloading heavy objects after the container is opened and during transportation, resulting in the container falling apart and the goods collapsing and being damaged.

[0004] The information disclosed in this background art section is only intended to enhance the overall understanding of the present utility model and should not be regarded as an admission or any form of implication that this information constitutes prior art already known to those of ordinary skill in the art.

[0017] Such as Figure 1-2As shown in the figure, a connecting, fixing and locking device for a new type of split-foldable container includes a lock housing 1, a lock core 2, a support mechanism, a rotary mechanism, a reset mechanism, and a button mechanism. A support mechanism and a button mechanism are arranged inside the lock housing 1. The support mechanism includes a fixing plate 3 and a lock pin 4. The fixing plate 3 is arranged inside the lock housing 1, and the lock pin 4 is arranged on the fixing plate 3. The rotary mechanism is a gear 5, and the gear 5 is rotatably arranged on the lock pin 4. The lock core 2 is arranged on the gear 5, and the end of the lock core 2 extends to the outside of the lock housing 1 to form a lock head 6. The reset mechanism includes a spring 7, a stop screw 8, and a fixing seat 9. The fixing seat 9 is arranged inside the lock housing 1. One end of the spring 7 is fixed on the fixing seat 9, and the other end of the spring 7 is fixed on the lock core 2 through the stop screw 8. The stop screw 8 is perpendicularly arranged with respect to the fixing seat 9. The button mechanism includes a transmission shaft 10, a shaft seat 11, a shaft cylinder 12, and a rack 13. The shaft seat 11 is arranged on the shaft cylinder 12, and the transmission shaft 10 passes through the shaft seat 11 and the shaft cylinder 12. The transmission shaft 10 can vertically move in the shaft seat 11 and the shaft cylinder 12 when a force is applied. Grooves are formed on the surfaces of the shaft cylinder 12 and the shaft seat 11 facing the gear 5, and a rack 13 is arranged on the surface of the transmission shaft 10 facing the gear 5. The rack 13 is located in the groove and meshes with the gear 5.

[0018] At the connecting corner of the door and the side plate of the split-foldable container, the lock head 6 of the connecting, fixing and locking device passes through the lock hole to connect and fix the door and the side plate. When it is necessary to open the connection between the door and the side plate, place the end 14 of the transmission shaft 10 extending to the outside of the lock housing 1 on a special unlocking tool, apply a force of more than 50 kg to the transmission shaft 10 through the unlocking tool, press the transmission shaft 10 downward. The transmission shaft 10 drives the rack 13 to descend, and the rack 13 drives the gear 5 to rotate, converting the vertical movement into a rotary movement. The gear 5 drives the lock core 2 to rotate 90°. The spring 7 is torsionally stressed and stores the torsion force. The lock head 6 is removed from the lock hole, and the door and the side plate are disassembled. The transmission shaft 10 is removed from the unlocking tool, and the spring 7 releases the torsion force, driving the lock core 2 to rotate and reset, and the gear 4 drives the rack 13 to rise and reset. When it is necessary to reconnect and fix the door and the side plate, place the transmission shaft 10 on the unlocking tool again and repeat the above operation. First, press the transmission shaft 10 downward, place the lock head 6 into the lock hole, and then the spring 7 resets, driving the lock head 6 to rotate and fix in the lock hole, connecting and fixing the door and the side plate. The connecting, fixing and locking device can achieve a 90° rotation of the lock core even in a limited space, ensuring the contact area between the lock head and the lock hole. The connecting lock device will not become unhooked during loading, unloading and transportation, ensuring that the container will not fall apart and ensuring the safety of the goods.
