Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example

[0035] Example 1: Figures 1 to 7 As shown, the present invention provides a fresh-keeping box cover with a buckle that can be rotatably removed, comprising: a fresh-keeping cover 1 and a sealing cover 5, a fixed shaft 9 is arranged on the side of the fresh-keeping cover 1, a buckle structure 2 is arranged on the fixed shaft 9, a clamping block 8 is arranged below the buckle structure 2, a rotating buckle 7 is fixedly arranged on the side of the buckle structure 2 away from the fresh-keeping cover 1, and a vent hole 4 is arranged above the fresh-keeping cover 1; two groups of sealing plugs 6 are fixedly arranged below the sealing cover 5.

[0036] In this embodiment, the fresh-keeping cover 1 and the buckle structure 2 constitute the snap-fastened rotatable and detachable fresh-keeping box cover device involved in the present application, realizing a snap-fastened rotatable and detachable fresh-keeping box cover.

[0037] In this embodiment, the rotating buckle 7 is fixedly arranged on the side of the buckle structure 2 away from the fresh-keeping cover 1, which enhances the firmness of the connection between the fresh-keeping box cover and the box body.

[0038] In this embodiment, after the buckle structure 2 is rotated to a suitable position, the card block 8 can cooperate with the corresponding card groove or protrusion structure on the fresh-keeping box body to clamp and fix the buckle structure 2 to prevent it from accidentally rotating, thereby ensuring the stability of the connection between the fresh-keeping box cover and the box body.

[0039] It should be noted that the buckle structure 2 can rotate around the fixed axis 9 to achieve the opening and closing operation of the fresh-keeping box cover.

[0040] Specifically, the buckle structure 2 and the fixed shaft 9 are provided in several groups, and grooves are provided at the upper and lower ends and the left and right sides of the fresh-keeping cover 1. The fixed shaft 9 is fixedly connected to the inner walls of the two ends of the groove. The fixed shaft 9 penetrates and rotates to connect the buckle structure 2, and the buckle structure 2 is rotatably connected to the fresh-keeping cover 1.

[0041] In this embodiment, the grooves arranged at the upper and lower ends and the left and right sides of the fresh-keeping cover 1 provide a precise installation position for the fixing shaft 9 .

[0042] Specifically, the rotating buckle 7 is in a hook shape, and a clamping groove 11 is provided at the bottom of the rotating buckle 7. When the clamping groove 11 on the clamping structure 2 is aligned with the fixed shaft 9 and force is applied, the clamping groove 11 is clamped with the fixed shaft 9, and the fixed shaft 9 clamps the rotating buckle 7.

[0043] As a preferred embodiment, the buckle structure 2 and the fixed shaft 9 are provided in several groups, and the sealing performance between the fresh-keeping box cover and the fresh-keeping box is improved by increasing the buckling points.

[0044] Embodiment 2:

[0045] On the basis of Example 1, in order to further improve the air tightness of the vent hole 4, a sealing cover is arranged on the vent hole 4 to further seal the vent hole 4;

[0046] Specifically, the buckle structure 2 is rotatably connected to the clamping block 8, and when in use, it is ensured that the clamping block 8 is buckled on both sides of the fresh-keeping box.

[0047] It should be noted that the clamping block 8 is rotatably connected to the buckle structure 2, and has a stable connection effect after being fastened. When the fresh-keeping box is subjected to external force, the clamping block 8 can fine-tune its own position by rotating to better disperse the external force and avoid loosening of the buckle due to large force.

[0048] Specifically, a slot 3 is fixedly provided above the fresh-keeping cover 1 , and two groups of vent holes 4 are fixedly provided on the slot 3 , and the vent holes 4 are parallel to each other.

[0049] As a preferred embodiment, two groups of vent holes 4 are fixedly arranged on the card slot 3 and are parallel to each other, so as to adjust the gas environment inside the fresh-keeping box.

[0050] Specifically, the sealing cover 5 is consistent in size with the card slot 3. When the sealing cover 5 is aligned with the card slot 3 and force is applied, the sealing plug 6 is snapped into the bottom of the buckle structure 2. The bottom of the sealing plug 6 is spherical, ensuring that the sealing cover 5 fits tightly with the buckle structure 2 and the sealing of the fresh-keeping box.

[0051] It should be noted that when the sealing cover 5 is installed on the card slot 3, the sealing plug 6 at the spherical bottom can adaptively fill the tiny gap that may exist at the bottom of the buckle structure 2. The sealing cover 5 fits tightly against the buckle structure 2, effectively preventing the entry and exit of air, moisture and odor, thereby ensuring the closedness of the fresh-keeping box.

[0052] Specifically, a buckle slot 10 is provided on one side of the card slot 3 , and the buckle slot 10 is fixedly arranged above the fresh-keeping cover 1 for removing the sealing cover 5 .

[0053] In this embodiment, when the sealing cover 5 needs to be separated from the card slot 3, the user can insert a finger or a tool into the buckle slot 10 and apply force to easily pry up or pull up the sealing cover 5, thereby improving the efficiency and comfort of using the fresh-keeping box.

[0054] When in use, when installing the buckle structure 2, align the buckle groove 11 on the buckle structure 2 with the fixed shaft 9 and apply force, at this time, the rotating buckle 7 will be elastically deformed, so that the fixed shaft 9 passes through the buckle groove 11 and is buckled in the rotating buckle 7, and then the buckle structure 2 is installed on the fresh-keeping cover 1. It is convenient for the installation of the safety buckle. When in use, the buckle structure 2 rotates around the clamping block 8, so that the clamping block 8 can be buckled on both sides of the fresh-keeping box, and then the cover can be buckled on the fresh-keeping box; then the sealing plug 6 on the sealing cover 5 is passed through the vent hole 4, so that the sealing cover 5 is buckled in the clamping groove 3, and the fresh-keeping box is closed. When it is necessary to remove the sealing cover 5, the hand buckles upward from the buckle groove 10 to remove the sealing cover 5.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
