The buckle mounting plate 7 is fixed to the bottom of the front end of the buckle connecting rod 6, and the slider buckle 8 is installed on the top of the buckle mounting plate 7. The bottom of the slider buckle 8 is a rectangular structure. The toggle button 5 is used to operate the buckle connecting rod 6, and the buckle connecting rod 6 can drive the slider buckle 8 to move, so that the slider buckle 8 can lock the lower box body plate 14.

[0027] As a preferred embodiment of the present utility model, the snap-in link 6 has a rectangular structure, and the four corners of the snap-in link 6 have an arc-shaped structure. A limiting sliding opening 9 is provided on the surface of the snap-in link 6. The limiting sliding opening 9 has a long strip structure, and the left and right ends of the limiting sliding opening 9 have an arc-shaped structure. The limiting sliding opening 9 is installed with a positioning rivet 10. When the snap-in link 6 moves laterally, the snap-in link 6 will be limited by the positioning rivet 10 and the limiting sliding opening 9, so that the snap-in link 6 can only move laterally.

[0028] As a preferred embodiment of the present utility model, the toggle button 5 is in a rectangular structure, and the four corners of the toggle button 5 are arc-shaped structures. A welding connecting plate 11 is provided at the bottom of the toggle button 5. The welding connecting plate 11 and the toggle button 5 are a smooth transition and an integrally processed structure. The welding connecting plate 11 is in a T-shaped structure. The welding connecting plate 11 is connected to the snap connecting rod 6 by welding. The welding connecting plate 11 at the bottom of the toggle button 5 is used to weld and fix the snap connecting rod 6, and the T-structured welding connecting plate 11 has high fixing stability and can also reduce material costs.

[0029] As a preferred embodiment of the utility model, an upper box body 3 is provided with an upper box body inner plate 12 inside, and the upper box body inner plate 12 is a rectangular structure. Sliding grooves 13 are provided on the left and right sides of the bottom of the upper box body inner plate 12. The sliding grooves 13 are inclined structures, and the two ends of the sliding grooves 13 are arc-shaped structures. The sliding grooves 13 opened on the upper box body inner plate 12 will facilitate the bottom guiding and sliding of the slider buckle 8, and help the slider buckle 8 to be stuck in the locking groove 15 of the lower box body inner plate 14.

[0030] As a preferred embodiment of the utility model, a lower box inner plate 14 is provided inside the lower insulation box body 2, and locking grooves 15 are provided on the left and right sides of the top of the lower box inner plate 14. The locking grooves 15 on the lower box inner plate 14 are for facilitating the embedding of the slider buckle 8 in the locking mechanism 4, thereby further achieving the locking and fixing of the lower box inner plate 14.

[0031] As a preferred embodiment of the utility model, an upper insulation material 16 is filled between the upper insulation box body 3 and the upper box inner plate 12. The upper insulation material 16 is foam. The upper insulation material 16 can ensure the insulation effect of the upper insulation box body 3. The upper insulation material 16 made of foam has low cost, light weight, good insulation effect, and can also reduce material costs.

[0032] As a preferred embodiment of the utility model, a lower insulation material 17 is filled between the lower insulation box body 2 and the lower box inner plate 14. The lower insulation material 17 is foam. The lower insulation material 17 can ensure the insulation effect of the lower insulation box body 2. The lower insulation material 17 made of foam has low cost, light weight, good insulation effect, and can also reduce material costs.

[0033] Working principle: during operation, the toggle button 5 moves laterally on the sliding track. At the same time, because the toggle button 5 and the buckle connecting rod 6 are connected by an I-shaped structure, locking can drive the buckle connecting rod 6 to move in the same plane. When the buckle connecting rod 6 moves laterally, the buckle connecting rod 6 will be limited by the positioning rivet 10 and the limiting sliding opening 9, so that the buckle connecting rod 6 can only move laterally. When the buckle connecting rod 6 moves, the buckle connecting rod 6 drives the slider buckle 8 to move. The structure of the slider buckle 8 cooperates with the upper box body plate 12, and the slider buckle 8 moves in the sliding groove 13 with an inclined structure on the upper box body plate 12. At this time, the relative position of the slider buckle 8 also changes. When the slider buckle 8 moves to the specified position, the slider buckle 8 can be snapped into the locking groove 15 on the lower box body plate 14, thereby realizing the locking function of the lower box body plate 14 and achieving the locking of the constant temperature box.
