DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Example 1

[0030] See also Figure 1-Figure 7 A portable packaging box comprises a box body 1 and a box cover 2 located at the upper part of the opening of the box body 1. A connecting ring 3 is fixedly connected to the side of the box cover 2. A connecting step 4 adapted to the connecting ring 3 is provided on the upper side of the box body 1. Several movable rods 5 are passed through the side of the connecting ring 3. A movable plate 6 is fixedly connected to the side of the movable rod 5. A movable groove 7 adapted to the movable plate 6 is provided on the inner side wall of the connecting ring 3. The end of the movable rod 5 close to the box body 1 is fixedly connected to a tightening plate 8. The end of the tightening plate 8 away from the movable rod 5 is fixedly connected to a limiting column 9. The inner wall of the connecting step 4 is provided with several limiting holes 10 that are adapted to the ends of the limiting columns 9. An elastic member 12 that is sleeved on the side of the movable rod 5 and has elasticity is fixedly connected between one side of the movable plate 6 and the inner wall of the movable groove 7. A releasing limit unit 11 that extends to the outside and is used for several limiting columns 9 to simultaneously disengage from the limiting holes 10 is provided in the tightening plate 8. A handle 22 for carrying is provided on the upper part of the box body 1, and a placement groove 21 that is adapted to the handle 22 is provided on the upper part of the box body 1. The handle 22 is rotatably connected to the placement groove 21.

[0031] Specific implementation method of this embodiment: When packaging a gift, place the gift in the box body 1, and sleeve the connecting ring 3 at the lower part of the box body 1 on the side of the connecting step 4. When sleeved, pay attention to aligning the position of the limiting column 9 with the limiting hole 10, press the box body 1 downward, and the limiting column 9 is squeezed by the position of the connecting step 4, and it shrinks in the movable groove 7. At this time, the elastic member 12 with elasticity is compressed, and the movable plate 6, the clamping plate 8 and the movable rod 5 all move in the movable groove 7. The elastic member 12 includes but is not limited to a spring. When the position of the limiting column 9 moves to adapt to the position of the limiting hole 10, the tension of the elastic member 12 with elasticity is released, and the elastic member 12 pushes the movable plate 6 to move in the movable groove 7. , the movable plate 6 drives the movable rod 5 to push the tightening plate 8 to move, and then pushes one end of the limiting column 9 into the limiting hole 10 to complete the connection between the box body 1 and the box cover 2. When the box cover 2 needs to be opened, the limiting unit 11 is released to disengage several limiting columns 9 from the limiting holes 10, and the box cover 2 can be removed, thereby improving the convenience of installation or disassembly between the box body 1 and the box cover 2. At the same time, through the above-mentioned arrangement, the box body 1 and the box cover 2 can be circular or polygonal, which improves the applicability of the overall packaging box. When the connected box body 1 and the box cover 2 need to be carried, the handle 22 located in the placement slot 21 is turned out, and the overall packaging box is convenient to carry through the handle 22.

[0032] Example 2

[0033] See also Figure 2 、 Figure 3 and Figure 4 This embodiment includes the above embodiment, which further includes: the limit release unit 11 includes a plurality of connecting rods 13 vertically penetrating the upper part of the box body 1 and extending from the lower end to the movable groove 7, and one end of the connecting rod 13 located in the movable groove 7 is fixedly connected to a wedge-shaped wedge-shaped extrusion block 15, and a through groove 14 is opened on the upper part of the connecting ring 3, which is connected to the movable groove 7 and adapted to the connecting rod 13, and extrusion grooves 16 adapted to the wedge-shaped extrusion block 15 are opened on the upper and lower sides of the movable rod 5, and a pulling ring 17 is fixedly connected between the upper ends of the plurality of connecting rods 13.

[0034] Specific implementation method in this embodiment: When the box body 1 and the box cover 2 need to be separated, the pulling ring 17 is pulled away from the box body 1, and the pulling ring 17 drives several through grooves 14 to move upward in the connecting rod 13. The inclined surface of the wedge-shaped extrusion block 15 squeezes the extrusion groove 16, thereby pushing the movable rod 5 to slide in the movable groove 7. The movable rod 5 drives the limiting column 9 to disengage the limiting hole 10 through the tightening plate 8, and the box cover 2 can be removed, making it easy to remove the box cover 2.

[0035] Example 3

[0036] See also Figure 4 and Figure 6This embodiment includes all the above embodiments, and further includes: an annular groove 18 adapted to the pulling ring 17 is opened on the upper part of the box body 1, and a stacking ring 23 adapted to the annular groove 18 is fixedly connected to the bottom of the box body 1.

[0037] The specific implementation method of this embodiment is: the pulling ring 17 is located in the annular groove 18, and the pulling ring 17 is lower than the upper part of the annular groove 18. When multiple packaging boxes need to be stacked and transported, the stacking ring 23 at the lower part of the box body 1 is clamped in the annular groove 18 to limit the upper and lower packaging boxes, thereby improving the stability of the packaging boxes after stacking.

[0038] Example 4

[0039] See also Figure 3 and Figure 5 This embodiment includes all the above embodiments, which further includes: arc-shaped arc grooves 19 are provided on the facing sides of the connecting ring 3 and the connecting step 4, and an elastic ring 20 with elasticity is embedded in the arc groove 19. A guide bevel 24 for guiding is provided on the side of the connecting ring 3 close to the box body 1, and the end of the limiting column 9 away from the clamping plate 8 is in an arc shape.

[0040] Specific implementation method in this embodiment: before installing the box cover 2, the elastic ring 20 with elasticity is clamped in the arc groove 19. When the box cover 2 is pressed down, the connecting ring 3 squeezes the elastic ring 20 to improve the sealing after the box cover 2 is connected to the box body 1. At the same time, the elastic ring 20 has an upward thrust on the connecting ring 3, so that the limiting column 9 is stably clamped in the limiting hole 10, improving the stability after the box cover 2 and the box body 1 are connected. The guide bevel 24 cooperates with one end of the limiting column 9 to be in an arc shape, which plays a role in guiding the connecting ring 3 and the limiting column 9, making it convenient to put the connecting ring 3 on the side of the connecting step 4.

[0041] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
