DETAILED DESCRIPTION

[0020] The following is combined with Figures 1 to 5 The utility model is described in detail.

[0021] A carton with a buckle according to the present utility model includes a box body 1 and a buckle assembly 2. On both sides of the box body 1 in the first direction, there are first side plates 11. On both sides of the box body 1 in the second direction, there are second side plates 12. The two sides of the first side plate 11 are respectively connected to the second side plates 12. At the top of the second side plates 12, there is a cover plate 13. At a position near the top of the first side plate 11, there is a positioning port 14. The buckle assembly 2 is provided with a fixing buckle 3 installed in the positioning port 14. Inside the fixing buckle 3, there is a cavity 31. Inside the cavity 31, there is a fixing rod 32. At the corner of the cover plate 13, there is a step portion 15. The buckle assembly 2 is provided with a positioning housing 4. The positioning housing 4 is snap-fitted with the step portion 15. On one side of the positioning housing 4, there is a swingable buckle plate 41. At the end of the buckle plate 41, there is a limit block 42 that can be inserted into the cavity 31. On the limit block 42, there is a card slot 43 that can be engaged with the fixing rod 32. The size of the limit block 42 corresponds to that of the cavity 31. After the limit block 42 is inserted into the cavity 31, it can be fixed in the cavity 31, which can prevent the buckle plate 41 from shaking after the buckle assembly 2 is buckled. In the solution of the present utility model, after the cover plate 13 covers the top of the first side plate 11, the positioning housing 4 and the fixing buckle 3 are in corresponding upper and lower positions. At this time, the limit block 42 of the buckle plate 41 is inserted into the cavity 31 of the fixing buckle 3, and the card slot 43 is engaged with the fixing rod 32 to buckle the buckle assembly 2. The cover plate 13 can be fixed without using tools such as tapes and straps. The opening and closing methods of the carton box body 1 are convenient and fast, and will not damage the surface of the box body 1 or destroy the structure of the box body 1, improving the service life of the box body 1 and maintaining the aesthetic property of the box body 1.

[0022] Both ends of the fixing buckle 3 are provided with limit portions 33. The limit portion 33 at one end of the fixing buckle 3 abuts against one side surface of the second side plate 12, and the limit portion 33 at the other end of the fixing buckle 3 abuts against the other side surface of the second side plate 12, so that the fixing buckle 3 is fixed on the positioning port 14, which can prevent the fixing buckle 3 from falling off.

[0023] Inside the positioning housing 4, there are first anti-slip convex lines 44. The step portion 15 is a concave step structure, so that the thickness of the step portion 15 is less than the thickness of other parts of the cover plate 13. The overall thickness of the positioning housing 4 is equal to or slightly greater than the thickness of the cover plate 13. After the positioning housing 4 is snap-fitted on the step portion 15, it will not bulge too much and affect the appearance property of the carton too much. The first anti-slip convex lines 44 can provide a large frictional resistance, making the connection between the positioning housing 4 and the step portion 15 more stable.

[0024] On one side of the positioning housing 4, there are two extension blocks 45. Between the two extension blocks 45, there is a rotating shaft 451. The buckle plate 41 is fixedly connected to the rotating shaft 451. The rotating shaft 451 is movably connected to the extension blocks 45, so that the buckle plate 41 moves in a swinging manner.

[0025] The second anti-slip protrusions 46 are provided on the buckle plate 41. The second anti-slip protrusions 46 are arranged on one side surface of the buckle plate 41. When the locking component 2 is buckled, the user can press the buckle plate 41 with fingers and insert the limiting block 42 into the cavity 31. The second anti-slip protrusions 46 provide frictional resistance to prevent the fingers from slipping.

[0026] The end of the buckle plate 41 extends outward to form a rocker 47. When the locking component 2 is opened, the rocker 47 can be toggled with fingers to pull out the limiting block 42 from the cavity 31, which is convenient to use.

[0027] The locking component 2 is made of plastic. The plastic locking component 2 has a low cost and is not easily damaged. After the box body 1 is damaged, the locking component 2 can still be removed and installed on other cartons for use, and can be reused.

[0028] Both the inner and outer surfaces of the box body 1 are coated with a waterproof coating. Since the carton of the present utility model is provided with the locking component 2 and the cost is slightly higher than that of the traditional packaging carton, the carton of the present utility model is more suitable for long-term use. Coating the waterproof coating can improve the waterproof and moisture-proof performance of the box body 1 and extend the service life of the box body 1.

[0029] The above content is only the preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manners and application scopes. The content of this specification should not be construed as a limitation to the present utility model.
