[0020] 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.

[0021] Reference Figure 1-5 The top of the box body 1 is fixed with a limiting ring 3, and the outer side of the box body 1 is movably sleeved with a fixing ring 4, and the outer side of the box cover 2 is sleeved with a connecting frame 5. The connecting frame 5 has an L-shaped cross section and conflicts with the edge of the box cover 2. A clamping mechanism 6 is provided between the connecting frame 5 and the fixing ring 4, and a lifting mechanism 7 is fixed on the top of the connecting frame 5. The foam packaging box can conveniently fix the box body 1 and the box cover 2 by the fixing ring 4 and the connecting frame 5 in combination with the clamping mechanism 6. It is convenient and quick to package without tape, and the fixing ring 4 and the connecting frame 5 can be quickly disassembled when not in use, and can be used with different packaging boxes. The lifting mechanism 7 on the top makes it convenient to lift the packaging box for movement.

[0022] In this embodiment, the clamping mechanism 6 includes a protrusion 61 and a clamping block 62. The protrusion 61 is fixed on the four sides of the connecting frame 5, and the clamping block 62 is fixed on the four sides of the fixing ring 4. A hook 63 is fixed to the bottom of the protrusion 61. The hook 63 has a certain elasticity and can be deformed when pressed until the hook 63 automatically resets to complete the clamping. A clamping groove 64 is provided on the surface of the clamping block 62, and the hook 63 is clamped with the clamping groove 64. The hook 63 can connect the fixing ring 4 and the connecting frame 5, and can fix the box cover 2 to the top of the box body 1. A plurality of hooks 63 and the clamping block 62 are arranged correspondingly. The clamping groove 64 is an L-shaped groove, and its two ends pass through the two vertical surfaces of the clamping block 62.

[0023] Furthermore, the lifting mechanism 7 includes several fixed seats 71 and lifting straps 72. Several of the fixed seats 71 are fixed on both sides of the top of the connecting frame 5. Both ends of the lifting straps 72 are fixed with connecting heads 73. A connecting component 8 is provided between the connecting head 73 and the fixed seat 71. The lifting straps 72 can facilitate the staff to lift the packaging box and facilitate carrying and moving.

[0024] Furthermore, the connecting component 8 includes an empty slot 81 and at least two limiting holes 82, at least two of the limiting holes 82 are opened on the inner side of the fixed seat 71, and the empty slot 81 is opened on both sides of the connecting head 73. The interior of the empty slot 81 is slidably connected with a movable plate 83, and the outer side of the movable plate 83 is fixed with a clamping column 84, and the clamping column 84 passes through the empty slot 81 and is movably connected with the limiting holes 82. A spring 85 is provided between the movable plate 83 and the empty slot 81. The clamping column 84 cooperates with the spring 85 to facilitate the removal of the connecting head 73 from the fixed seat 71, and the lifting strap 72 can be easily removed.

[0025] In addition, the top of the limiting ring 3 conflicts with the connecting frame 5, and the bottom of the limiting ring 3 conflicts with the fixing ring 4. The limiting ring 3 and the fixing ring 4 can limit the box cover 2, and the outer side of the limiting ring 3 is flush with the connecting frame 5 and the fixing ring 4.

[0026] It should be noted that a number of reinforcing ribs 9 are fixed to the outer surface of the box body 1, and a groove 10 is provided on the inner side of the fixing ring 4, which fits the reinforcing ribs 9 and is slidably connected to the reinforcing ribs 9. The reinforcing ribs 9 can not only increase the strength of the box body 1, but also guide and limit the fixing ring 4.

[0027] Working method: When sealing the packaging box, the staff places the box cover 2 on the inner side of the connecting frame 5 and presses it tightly, then puts the fixing ring 4 from the bottom of the box body 1 upward onto the surface of the box body 1, and then continues to squeeze upward until it contacts the limit ring 3, and then clamps the hook 63 at the bottom of the connecting frame 5 into the clamping groove 64 of the clamping block 62. After clamping in sequence, the sealing of the box cover 2 is completed. When moving, you only need to use your hand to pass through the lifting belt 72 and pull it upward to move it. When removing the lifting belt 72, you only need to push the moving plate 83 outward. The moving plate 83 squeezes the spring 85 and drives the clamping column 84 to disengage from the limiting hole 82, and then the lifting belt 72 can be removed.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
