[0023] Among them, the sliding block 10 is slidably connected to the lock seat 7, the locking switch 11 is arranged in the lock seat 7, and the lock buckle 9 is arranged on the surface of the locking switch 11. When using the locking member 8, the lock buckle 9 is flipped so that its top end is located in the buckle lock groove 6, the locking switch 11 is pried, the sliding block 10 is squeezed, and the lower end of the lock buckle 9 is pulled. The locking switch 11 stops being pried after rotating 90°. At this time, the sliding block 10 cooperates with the lock seat 7 to hold the locking switch 11 fixed, and the lock buckle 9 is tightly buckled with the buckle lock groove 6 on the box cover 3 under the action of the locking switch 11, thereby fixing and locking the box cover 3 and the lunch box 1.

[0024] Secondly, the sliding shaft 12 is fixedly connected to the sliding block 10 and is slidably connected to the lock seat 7. The two ends of the return spring 13 are respectively fixedly connected to the sliding block 10 and the lock seat 7, and are sleeved on the surface of the sliding shaft 12. When the sliding block 10 is squeezed by the locking switch 11, it slides and descends in the lock seat 7, driving the sliding shaft 12 to descend and squeeze the return spring 13 with the lock seat 7. Under the action of the return spring 13, the sliding block 10 is always in a state of close contact with the locking switch 11. After the locking switch 11 is rotated, under the action of the return spring 13, the sliding block 10 cooperates with the lock seat 7 to hold the locking switch 11 against and fixed.

Since the two side surfaces of the locking block 16 are perpendicular to each other and the connecting surface is a curved surface, similar to a cam, when the locking block 16 rotates, it will press down the sliding block 10, causing the sliding block 10 to slide smoothly downward within the lock base 7 under the action of the two auxiliary rods 15, driving the sliding shaft 12 to slide downward and compressing the return spring 13. Since the contact surface between the locking block 16 and the sliding block 10 is a curved surface, after rotating 90°, the sliding block 10 is pushed upward by the return spring 13 and cooperates with the lock base 7 to hold and fix the locking block 16. While the locking block 16 rotates, the mounting frame 17 rotates accordingly and pulls the lower end of the lock catch 9 to swing. When the rotation of the locking block 16 is completed, the mounting frame 17 tightly pulls the lower end of the lock catch 9, causing the top end of the lock catch 9 to tightly fasten the locking groove 6 on the lid 3, so as to fixedly lock the lid 3 and the lunch box 1 in cooperation with the other fixing assembly 5.

[0027] When sealing, buckle the box cover 3 above the lunch box 1 and press it, so that a plurality of the sealing gaskets 4 are squeezed between the lunch box 1 and the partition 2, sealing the interior of the lunch box 1. Then turn the two latches 9 so that their tops are located in the locking grooves 6, and through the cooperation of the locking member 8 and the lock seat 7, pull down the latch 9 so that the top of the latch 9 tightly buckles the locking groove 6. With the cooperation of the two fixing components 5, the box cover 3 is firmly fixed above the lunch box 1; when the locking switch 11 is toggled, the switch plate 18 is toggled, and the locking block 16 rotates. Since the two side surfaces of the locking block 16 are perpendicular to each other and the connecting surface is a curved surface, similar to a cam, when the locking block 16 rotates, it will press down the sliding block 10, so that the sliding block 10 slides smoothly downward in the lock seat 7 under the action of the two auxiliary rods 15, driving the sliding shaft 12 to slide downward and squeezing the return spring 13. Since the contact surface between the locking block 16 and the sliding block 10 is a curved surface, after rotating 90°, the sliding block 10 is pushed upward under the action of the return spring 13, and cooperates with the lock seat 7 to hold and fix the locking block 16. While the locking block 16 rotates, the mounting frame 17 rotates accordingly and pulls the lower end of the latch 9 to swing. When the rotation of the locking block 16 is completed, the mounting frame 17 tightly pulls the lower end of the latch 9, so that the top of the latch 9 tightly buckles the locking groove 6 on the box cover 3, so that with the cooperation of the other fixing component 5, the box cover 3 and the lunch box 1 are fixedly locked; when the sliding block 10 slides in the lock seat 7, the two auxiliary rods 15 can make the sliding of the sliding block 10 more stable, and the protective plate 14 slides in the lock seat 7 along with the sliding block 10, covering the gap below the sliding block 10 to prevent foreign objects from entering the lock seat 7 and damaging the return spring 13, avoiding the problem that the existing lunch box does not clearly express the sealing structure and it is inconvenient to find a suitable sealing object during use, which may cause food spillage, and achieving the effect of fixing and sealing the lunch box 1 through a double-latching structure.
