The sliding plate 25 is slidably connected to the sliding opening 24, and the connecting plate 23 can be inserted into the connecting groove 22. The sliding plate 25 can drive the curved plate 26 to move, so that the curved plate 26 is inserted into the bayonet 27, and the connecting plate 23 and the box cover 11 can be fixed. At the same time, a single person can complete the fixation of the box cover 11, and the box body 1 can be packaged without tape. The elastic component includes a push plate 41 fixedly connected to both sides of the sliding plate 25, a push rod 42 fixedly connected to one side of the push plate 41, two second grooves 43 provided on the inner wall of one side of the connecting groove 22, and a second spring 44 sleeved on the outside of the push rod 42. The push rod 42 is slidably connected to the second groove 43, and the two push rods 42 are connected to the two second springs. The two grooves 43 correspond one to one, and the two ends of the second spring 44 are fixedly connected to the push plate 41 and the connecting groove 22 respectively. The push plate 41 can move synchronously with the sliding plate 25, so that the second spring 44 can be deformed by force. The push rod 42 can prevent the second spring 44 from being skewed and damaged. The reset of the second spring 44 can push the arc plate 26 to reset, so that the arc plate 26 is inserted into the bayonet 27 to automatically fix the box cover 11, which can improve the installation efficiency. Guide grooves 51 are respectively provided on both sides of the sliding port 24, and a guide block 52 is slidably connected in the guide groove 51. The guide block 52 is fixedly connected to the sliding plate 25, and the guide block 52 can move synchronously with the sliding plate 25 to ensure the sliding The movement stability of the plate 25 is prevented from being offset. The guide block 52 is in the shape of an I-shape and the guide groove 51 is in the shape of a T-shape, which can prevent the guide block 52 from disengaging from the guide groove 51 and improve the sliding stability of the guide block 52. A pull plate 251 is provided on one side of the sliding plate 25. The pull plate 251 is fixedly connected to the sliding plate 25, which can facilitate the movement of the sliding plate 25 and the curved plate 26, so that the curved plate 26 is disengaged from the bayonet 27, which is convenient for removing the box cover 11. A sliding portion 231 is provided on one side of the bottom of the connecting plate 23. The sliding portion 231 is in the shape of an arc and can contact the curved plate 26, so as to squeeze the curved plate 26 to make it move laterally, thereby facilitating the fixing of the box cover 11.

[0023] See also Figure 1 、 Figure 3 as well as Figure 4The ejection component includes first grooves 31 respectively opened on both sides of the bottom of the connecting groove 22, a pressure rod 32 provided in the first groove 31, a first spring 33 fixedly connected to one end of the pressure rod 32, and a pressure plate 34 fixedly connected to the other end of the pressure rod 32. The pressure rod 32 is slidably connected to the first groove 31. When the box cover 11 is fixed, the connecting plate 23 can push the pressure plate 34 downward, so that the first spring 33 is deformed under force.

[0024] Working principle: When working, after the box body 1 is filled with items, the box cover 11 is placed on the box body 1. At this time, the connecting plate 23 is inserted into the connecting groove 22. During the downward movement of the connecting plate 23, the sliding portion 231 contacts the curved plate 26 and squeezes the curved plate 26 to make it move laterally. The movement of the curved plate 26 drives the push plate 41 to move. The movement of the push plate 41 causes the second spring 44 to deform. As the connecting plate 23 moves downward, the connecting plate 23 contacts the pressure plate 34. The connecting plate 23 pushes the pressure plate 34 downward. The downward movement of the pressure plate 34 causes the first spring 33 to deform. When the curved plate 26 contacts the bayonet 27, the second spring 44 resets, pushing the curved plate 26 to reset, so that the curved plate 26 is inserted into the bayonet 27. , and then the connecting plate 23 and the box cover 11 can be fixed, and the box cover 11 can be automatically locked, which can improve efficiency and simplify operation. When the box cover 11 needs to be removed, the two pull plates 251 are pulled to both sides, and the pull plates 251 can drive the sliding plate 25 and the curved plate 26 to move, and the curved plate 26 moves out of the bayonet 27. At this time, the first spring 33 is reset, which can push the connecting plate 23 and the box cover 11 to move upward, so that the bayonet 27 moves to above the curved plate 26, release the pull plate 251, and then remove the box cover 11. The above is the working process of the entire device, and the contents not described in detail in this manual belong to the existing technology known to professional and technical personnel in this field.
