Obviously, the use of the corresponding directional words does not constitute a limitation on the protection scope of this scheme.

[0038] See also Figure 1 and Figure 2 , Figure 1 A schematic diagram of a single-button lunch box provided by the utility model, Figure 2 for Figure 1 Schematic diagram of the exploded structure of the single-buckle lunch box shown.

[0039] like Figure 1 , Figure 2 As shown, the utility model provides a single-buckle lunch box, comprising a box body 10 and a box cover 20 arranged at the open end of the box body 10. The box body 10 and the box cover 20 are connected by a single-buckle locking device, and the box cover 20 can be opened or closed.

[0040] In this embodiment, the box body 10 is a rectangular box body. Obviously, the box body 10 is not limited to the rectangular box body in this embodiment, and a circular box body may also be used.

[0041] The single-buckle locking device includes a hanging plate 31 , an inserting plate 32 , a buckle plate 33 and a hook 34 .

[0042] The hanging plate 31 is arranged on the side wall of the open end of the box body 10, and a plug hole 311 is arranged on the hanging plate 31. The upper end of the hanging plate 31 is arranged to be inclined outwardly toward the outside of the box body 10.

[0043] like Figure 3 As shown, the plug plate 32 is arranged on the outer side wall of the box cover 20 and is matched with the plug hole 311 on the hanging plate 31 . A hook 321 is provided at the end of the plug plate 32 .

[0044] The pinch plate 33 is disposed on the outer side wall of the box cover 20 , and is disposed opposite to the inserting plate 32 . The upper end of the pinch plate 33 is hinged to the side wall of the box cover 20 , and a claw 331 is disposed at the lower end of the pinch plate 33 .

[0045] The hook 34 is arranged on the outer wall of the box body 10, and is arranged opposite to the hanging plate 31. The hook 34 matches with the claw 331 at the lower end of the buckle plate 33 to achieve locking and unlocking between the box cover 20 and the box body 10. In this embodiment, the hook 34 is implemented by a step structure, which is simple in structure, high in strength, and not easy to be damaged.

[0046] In addition, in the present embodiment, the outer side walls of the box body 10 and the box cover 20 are respectively provided with a first groove 11 and a second groove 21 adapted to the buckle plate 33, and the main body of the buckle plate 33 is respectively embedded in the first groove 11 and the second groove 21 in the closed state, and the outer side surface of the main body of the buckle plate 33 is flush with the outer side surfaces of the box body 10 and the box cover 20, and there is no protrusion on the outer side surface, so it will not occupy too much external space.

[0047] The upper end of the buckle plate 33 is further provided with an extension plate 332, which is tilted upward toward the outside of the box body 10. By lifting the outer end of the extension plate 332 upward, the buckle plate 33 is rotated around the rotation axis thereon, and the claw 331 at the lower end of the buckle plate 33 is disengaged from the hook 34 on the box body 10, completing the unlocking operation, making the unlocking operation more convenient.

[0048] The ends of the hanging plate 31 and the extension plate 332 are arc-shaped, which enhances the comfort of use.

[0049] This embodiment is used as a lunch box. A food box 40 is provided in the inner cavity of the box body 10. The shape of the food box 40 is adapted to the inner cavity of the box body 10 and has a plurality of compartments 41 for placing different food items. In addition, a separate receiving cavity 42 is provided at the center of the food box 40. The receiving cavity 42 is used to place a soup bowl 43. The soup bowl 43 can be provided with a sealing cover to prevent the soup from overflowing from the soup bowl 43, soaking the food items and affecting the taste.

[0050] When the present embodiment is used as a lunch box, a tableware cover plate 50 can be placed on the food box 40, and a tableware buckle 51 is provided on the tableware cover plate 50 for clamping chopsticks, spoons and other tableware. In addition, a vent is also provided on the tableware cover plate 50, and a sealing plug 52 is provided on the vent.

[0051] When the box cover 20 is opened, the tableware cover plate 50 can be used instead of the box cover, and opening the sealing plug 52 can allow the food in the food box 40 to dissipate heat. This design can prevent dust and other debris from falling into the food box 40, thereby improving hygiene and safety.

[0052] The method of using the utility model is as follows:

[0053] The insert plate 32 on the box cover 20 is inserted into the insert hole 311 on the hanging plate 31, the box cover 20 is flipped down and buckled on the open end of the box body 10, and the buckle plate 33 is rotated so that the claws at the lower end of the buckle plate 33 are clamped on the hooks on the box body 10, and the box cover 20 is locked with the box body 10. A sealing ring can be provided between the box body 10 and the box cover 20 or the tableware cover plate 50 to improve the sealing performance. Such sealing structure is a conventional technology in the art and will not be described in detail here.

[0054] When the box cover 20 needs to be opened, the lower end of the buckle plate 33 is pulled outward by hand or the extension plate 331 at the upper end of the buckle plate 33 is pushed, the buckle plate 33 rotates, the claw 331 at the lower end of the buckle plate 33 is disengaged from the hook 34 on the box body 10, the claw 331 is unlocked from the hook 34, the box cover 20 is flipped upward, tilted at a certain angle, and then the plug plate 32 is pulled out from the insertion hole to remove the box cover 20. The operation of opening the box cover 20 can be completed with one hand, which is convenient to use.

[0055] Based on the description of the above specific embodiments, the single-button lunch box and the single-button locking device provided by the utility model have the following advantages compared with the prior art:

[0056] First, the lid can be opened with one hand, which is convenient to use.

[0057] Second, the outer side walls of the box body and the box cover are provided with a first groove and a second groove matched with the buckle plate. The buckle plate is embedded in the first groove and the second groove when closed, and there is no protrusion on the outer side surface, which will not occupy too much external space.

[0058] Third, an optional cutlery cover is available to facilitate carrying cutlery.

[0059] Fourth, the cutlery cover is also provided with a vent, and a sealing plug is provided on the vent. The cutlery cover can be used instead of the box cover. Opening the sealing plug allows the food in the box to dissipate heat, which can prevent dust and other debris from falling into the food box, thereby improving hygiene and safety.
