Therefore, they are widely used in various occasions.

[0003] Traditional environmentally friendly cartons are in a folded state in the initial state. When people are packaging environmentally friendly cartons, they usually use transparent tape to stick the lid at the bottom of the box to the side wall of the box, put the items into the box and then perform the sealing operation. When people need to take out the items in the box for use, they need to manually tear off the tape on the carton. Since the tape has adhesive, when people remove the tape at the sealing point, the paper fibers at the bonding point of the box will be torn off together, thereby causing damage to the box and making the carton unable to be used multiple times. Therefore, it is necessary to propose a new structure to solve the problem that the environmentally friendly carton will be damaged and cannot be used multiple times when the packaging is removed.

DETAILED DESCRIPTION

[0019] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] This reusable environmentally friendly carton, such as Figure 1 and Figure 2 As shown, it includes a box body 1, which is set as a rectangular parallelepiped. The openings of the box body 1 along the length direction are rotatably connected with a box cover 1 2 and a box cover 2 3. The end of the box cover 1 2 away from the box body 1 is bonded with a clamping part. The clamping part and the gusset plate 4 are both made of plastic material, which has the characteristics of light weight and good bonding effect with paper articles, to prevent the clamping part from applying too much pressure to the box body 1 after the box body 1 is packaged, causing it to deform and affecting the service life of the box body 1. The top surface of the clamping part is rotatably connected with a gusset plate 4, which is used to fix the box cover 2 3, and the gusset plate 4 is close to the clamping part. A clamping cavity 5 is formed at one end near the box body 1, and the clamping cavity 5 is used to accommodate the buckle plate 4. When people package the box body 1, they first rotate the box cover 2 to a state parallel to the ground, and then rotate the box cover 2 3 into the clamping cavity 5, and apply a thrust to the buckle plate 4 in the direction close to the clamping plate 7 to make its side wall abut against the clamping part. The buckle plate 4 applies a force in the direction close to the clamping part to the box cover 2 3 at one end close to the box body 1, and the box cover 2 3 is fixed in the clamping cavity 5 by clamping between the buckle plate 4 and the clamping part, thereby achieving the purpose of packaging the box body 1.

[0021] like Figure 1 and Figure 2As shown, the clamping part includes a bottom plate 6 and a clamping plate 7 bonded to the top surface of the bottom plate 6, a receiving cavity 8 is formed between the clamping plate 7 and the bottom plate 6, the box cover 2 is bonded in the receiving cavity 8, the buckle plate 4 is rotatably connected to the end of the clamping plate 7 away from the bottom plate 6, and a clamping cavity 5 is formed between the buckle plate 4 and the bottom plate 6. The length of the bottom plate 6 along the width direction is one quarter of the length of the box body 1 along the width direction. The bottom plate 6 can share the force applied by the objects in the box to the sealing part of the box body 1, so that the supporting force of the bottom plate 6 and the buckle plate 4 on the box cover 2 and the box cover 3 is greater than the gravity of the objects in the box, so that the sealing will not be easily When the box cover 1 is opened, the gusset plate 4 is rotated and connected to the end of the splint 7 away from the bottom plate 6. The thickness of the gusset plate 4 is less than that of the splint 7. When the gusset plate 4 is rotated until its side wall is against the splint 7, a clamping cavity 5 for accommodating the box cover 2 3 is formed between the gusset plate 4 and the bottom plate 6. The height of the clamping cavity 5 is less than the thickness of the box cover 2 3. The box cover 2 3 is clamped more firmly in the clamping cavity 5 and will not fall out easily after pressure is applied by the items in the box. The top surface of the splint 7 is on the same horizontal plane as the top surface of the gusset plate 4, which can ensure that the packaged box body 1 is more stable when placed on the bottom surface.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, two connecting blocks are bonded to the end of the splint 7 away from the bottom plate 6, and the connecting blocks are bonded to the two ends along the width direction of the box body 1, and a rotating shaft 9 is bonded to the end of the connecting block away from the splint 7, and a hollow tube 10 is bonded to the end of the buckle plate 4 away from the bottom plate 6. The rotating shaft 9 is rotatably connected in the hollow tube 10, and the length of the hollow tube 10 is less than the distance between the two connecting blocks, so as to avoid the hollow tube 10 being stuck by the connecting blocks during rotation, and ensure the normal rotation of the rotating shaft 9 in the hollow tube 10. When people rotate the box cover 2 3 into the clamping cavity 5, the hollow tube 10 is rotated around the rotating shaft 9 by applying a thrust to the buckle plate 4 in the direction close to the bottom plate 6. When the side wall of the buckle plate 4 abuts against the side wall of the splint 7, the top surface of the splint 7 and the top surface of the buckle plate 4 are in the same horizontal plane, and the end of the buckle plate 4 close to the bottom plate 6 abuts against the box cover 2 3, and the box cover 2 3 is fixed in the clamping cavity 5, thereby achieving the packaging effect.

[0023] like Figure 2 , Figure 3 and Figure 5As shown, a clamping groove 11 is provided on the side wall of the clamping plate 7, and a clamping block 12 for fixing the clamping plate 4 is bonded on the side wall of the pinch plate 4. The cross-sectional area of ​​the clamping block 12 along the width direction is equal to the cross-sectional area of ​​the clamping groove 11 along the width direction, so that the clamping block 12 and the clamping groove 11 cooperate with each other to complete the clamping. A sliding groove 13 connected to the outside world is provided on the side wall of the clamping plate 7 near one end of the clamping groove 11. The two ends of the sliding groove 13 along the length direction are connected to the outside world through through holes. The diameter of the sliding groove 13 along the width direction is The sliding bar 14 is larger than the diameter of the through hole, and is slidably connected in the through hole. A slider is bonded to the outer wall of the sliding bar 14, and the slider is slidably connected in the sliding groove 13. The length of the slider is equal to the width of the sliding groove 13, which can make the slider slide more stably in the sliding groove 13. When the sliding bar 14 is subjected to a force applied by the outside world, the slider will resist the side wall of the sliding groove 13 along the length direction to prevent the sliding bar 14 from passing through the through hole. The length of the sliding bar 14 is greater than the length of the sliding groove 13, which is convenient for applying a force to the sliding bar 14 from the outside world.

[0024] like Figure 3 and Figure 5 As shown, in the initial state, the slide bar 14 passes through the through hole near one end of the clamping block 12, and the slider abuts against the side wall of the sliding groove 13 near one end of the clamping block 12. When the clamping block 12 abuts against the side wall of the clamping groove 11, the side wall of the clamping block 12 applies a thrust to the end of the slide bar 14 passing through the direction away from the clamping block 12, so that the slide bar slides along the sliding groove 13 until the slider abuts against the side wall of the sliding groove 13 away from the end of the clamping block 12, and the end of the slide bar 14 close to the clamping block 12 shrinks into the through hole, and the other end of the slide bar 14 passes through the through hole away from the end of the clamping block 12. When the package needs to be removed, a thrust is applied to the end of the slide bar 14 away from the clamping block 12, so that the end of the slide bar 14 close to the clamping block 12 passes through the through hole and applies a thrust to the side wall of the clamping block 12, so that the clamping block 12 is removed from the clamping groove 11.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, an inclined block 15 is provided at one end of the slide bar 14 close to the clamping groove 11, and the slide bar 14 and the inclined block 15 are integrally formed by bonding, and the distance between the end of the inclined block 15 close to the inner wall of the clamping groove 11 and the clamping block 12 is smaller than the distance between the end of the inclined block 15 away from the inner wall of the clamping groove 11 and the clamping block 12, and the side wall of the clamping block 12 is arranged in an inclined shape, so as to cooperate with the inclined block 15 to slide out of the clamping groove 11, and the distance between the end of the clamping block 12 close to the gusset plate 4 and the slide bar 14 is smaller than the distance between the end of the clamping block 12 and the clamping groove 11. The distance between the end of the block 12 away from the pinch plate 4 and the slide bar 14 is such that when the slide bar 14 passes through the through hole and slides toward the direction close to the clamping block 12, the inclined surface of the inclined block 15 will generate a component force in the direction perpendicular to the inclined surface. The side wall of the clamping block 12 is subjected to the thrust applied by the inclined block 15, so that the gap between the clamping block 12 and the inner wall of the clamping groove 11 increases, the clamping block 12 is disengaged from the clamping groove 11, the pinch plate 4 can rotate freely, the box cover 2 3 is no longer fixed, and the package is released.

[0026] Working principle: When people pack the carton, they rotate the box cover 2 3 to make it enter the clamping cavity 5, and apply a thrust to the gusset plate 4 close to the box body 1 to make the gusset plate 4 rotate. When the side wall of the gusset plate 4 abuts against the clamping plate 7, the clamping block 12 is embedded in the clamping groove 11. The end of the slide bar 14 close to the clamping block 12 is pushed by the side wall of the clamping block 12 in the direction of the sliding groove 13, so that the side of the slide bar away from the clamping block 12 abuts against the inner wall of the sliding groove 13 away from the clamping block 12, and the box cover 2 3 is fixed in the clamping cavity 5, that is, the packaging is completed. When the packaging needs to be removed, a thrust is applied to the end of the slide bar 14 that passes through the direction close to the clamping block 12, and the slider moves along the sliding groove 13 toward the direction close to the clamping block 12. The other end of the slide bar 14 passes through the through hole close to one end of the clamping block 12, and the tilting block 15 applies a thrust to the clamping block 12 away from the inner wall of the clamping groove 11, and the clamping block 12 is disengaged from the clamping groove 11, the buckle plate 4 can rotate freely, the box cover 2 3 is no longer fixed, and the packaging is released.
