[0015] Example:

[0016] The following is in conjunction with the appendix Figures 1-2 The present invention will be described in further detail below.

[0017] A top connection device, such as Figure 1 As shown, the structure is composed of two different enclosures joined together. The inner lining 2 and inner beam 1 of each enclosure are adjustablely connected by a fixing mechanism 4. Each enclosure has an inner beam 1 and an inner lining 2, which are connected by self-tapping screws. The self-tapping screws pass through and fix the high-strength heat insulation layer 3 between the inner beam 1 and the inner lining 2. The top of the inner beam 1 has a sloping groove 5, and the bottom of the inner beam 1 has a rectangular groove 6. The sloping grooves 5 and rectangular grooves 6 between the two different enclosures are aligned and filled with sealing strips 7 to form a double-layer sealing structure, improving leak-proof performance.

[0018] like Figure 2As shown, the fixing mechanism 4 includes a horizontal U-shaped base 8, fastening bolts 9, fastening nuts, a fastening pressure plate 10, and anti-slip components 11. The length of the inner side of the U-shaped base 8 is greater than the total length of the two boxes after they are joined together. The U-shaped base 8 covers the bottom of the two different boxes after they are horizontally aligned. The inner side of one end of the U-shaped base 8 abuts against the inner lining 2 of one of the boxes, and the other end of the U-shaped base 8 is located outside the inner lining 2 of the other box, leaving a gap. The end of this side is threaded, and a movable fastening bolt 9 passes through it, and the two are threaded together. The nut of the fastening bolt 9 faces outward, and the end of the fastening bolt 9 is provided with an integral fastening pressure plate 10. The side of the fastening pressure plate 10 opposite to the inner lining 2 of the box is the contact surface. The contact surface of the fastening pressure plate 10 is provided with a fixed anti-slip component 11. The fastening pressure plate 10 is pressed tightly against the inner lining 2 of the other box through the anti-slip component 11. The anti-slip component 11 is made of EPDM material (ethylene propylene diene monomer rubber). A fastening nut 12 is provided between the U-shaped base 8 and the bolt cap of the fastening bolt 9. That is, the fastening nut 12 is located on the outside of the U-shaped base 8, and the fastening nut 12 is threadedly connected to the fastening bolt 9.

[0019] When docking, align the two boxes, with the inner side of one end of the U-shaped base 8 abutting against the inner lining 2 of one of the boxes, keeping the U-shaped base 8 horizontal. Start rotating the fastening bolt 9 on the other side until it presses against the inner lining 2 of the other box. Rotate the locking nut until it presses tightly against the outer side of the U-shaped base 8 to complete the docking and fixing.

[0020] It should be noted that this specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
