[0023] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The same parts are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0024] Reference Figure 1-6 As shown, a universal protective packaging box includes a box body 1 and a cover body 2 for sealing the opening of the box body 1, a box body filler 3 for protecting articles is arranged in the box body 1, a cover body filler 4 is arranged in the cover body 2, the box body filler 3 and the cover body filler 4 are both made of slow rebound material, when the cover body 2 is covered on the box body 1, the box body filler 3 and the cover body filler 4 can abut against the articles placed in the packaging box and wrap the articles for protection.

[0025] The elastic wrapping of the items in the packaging box by the box body filler 3 and the cover body filler 4 can fully protect the items, and the use of slow-rebound materials can fully fit and wrap the surfaces of objects of various shapes when placing the items. After taking out the items, the box body filler 3 and the cover body filler 4 can return to a flat state, so there is no need to limit the shape of the protective plate in advance, so that the protective plate composed of the box body filler 3 and the cover body filler 4 can be recycled.

[0026] The box body portion 1 includes a box body frame 11 arranged in a frame structure, and the box body side panels 12 and the box body bottom panel 13 are detachably connected to the box body frame 11, and the box body side panels 12 and the box body bottom panel 13 together form a box body accommodating cavity for accommodating the box body filling piece 3. The cover body portion 2 includes a cover body frame 21 arranged in a frame structure, and the cover body side panels 22 and the cover body top panel 23 are detachably connected to the cover body frame 21, and the cover body side panels 22 and the cover body top panel 23 together form a cover body accommodating cavity for accommodating the cover body filling piece 4. The box body side panels 12, the box body bottom panel 13, the cover body side panels 22, and the cover body top panel 23 are all formed by splicing building blocks 5, and splicing patterns are provided on the outer surfaces of the box body side panels 12, the box body bottom panel 13, the cover body side panels 22, and the cover body top panel 23.

[0027] The box body side panels 12, the box body bottom panel 13, the cover body side panels 22, and the cover body top panel 23 can all be disassembled into the splicing blocks 5 that can be combined, which increases the function of the packaging box as a toy, can reduce the probability of consumers directly discarding the packaging box after purchase, and realize the secondary use of the packaging box. The splicing pattern formed by the splicing blocks 5 can be designed and printed by the merchant, meeting the merchant's personalized needs for the design of the packaging box appearance pattern. In addition, in order to make the box body side panels 12, the box body bottom panel 13, the cover body side panels 22, and the cover body top panel 23 formed by the splicing blocks 5 more flat and beautiful, the splicing blocks 5 are preferably square blocks that can be combined into a square structure when spliced.

[0028] After purchase, consumers first take out the items in the packaging box. If the splicing building blocks 5 are not needed, the merchant can recycle the entire packaging box. Since the box body filler 3 and the cover body filler 4 do not limit the protection of shapes, they can be used as protective plates for other items of different shapes. When consumers need to use the splicing building blocks 5, they only need to remove the splicing building blocks 5 from the packaging box, and the merchant can also recycle the remaining parts and then reinstall the splicing building blocks 5 on the box body frame 11 and the cover body frame 21. This not only meets the development of other additional functions of the packaging box, but also can fully recycle and reuse the packaging box, which can reduce the waste of resources and be more environmentally friendly.

[0029] A rigid clamping assembly 14 for fixing objects of different shapes is also provided in the box body 1. The rigid clamping assembly 14 includes a support column 141 vertically slidably connected to the box body frame 11, and a clamping plate 142 arranged on the support column 141 for clamping objects. The support columns 141 are arranged in pairs and the two support columns 141 slide relative to each other. A sliding locking assembly is arranged between the support column 141 and the box body frame 11. A movable hole 31 for the support column 141 to emerge is provided on the box body filling piece 3. A matching hole 41 is provided on the cover body filling piece 4, which can cooperate with the movable hole 31 to form a cavity for accommodating the rigid clamping assembly 14 when the cover body 2 and the box body 1 are covered.

[0030] The rigid clamping component 14 is provided to rigidly clamp the items in the packaging box. The box body filler 3 and the cover body filler 4 cooperate to protect the items. Although a protective shock-absorbing effect can be produced by the flexible squeezing of the items, it cannot prevent the items from moving between the box body filler 3 and the cover body filler 4 when impacted. In this way, the protective function of the box body filler 3 and the cover body filler 4 cannot be effectively exerted. Therefore, the items are first clamped by the clamping plate 142, and then the position of the support column 141 is fixed by the sliding locking component, so as to ensure that the items are stably placed in the packaging box. In this way, the box body filler 3 and the cover body filler 4 can be cooperated to further enhance the protective effect of the items.

[0031] In summary, the present invention clamps objects of different shapes through a rigid clamping assembly 14, and protects the clamped objects through a box body filler 3 and a cover body filler 4, and both are made of slow-rebound material, so there is no need to pre-restrict the shape of the protective plate, so that the protective plate composed of the box body filler 3 and the cover body filler 4 can be recycled. The box body side panels 12, the box body bottom panel 13, the box cover side panels, and the box cover top panel are formed by splicing blocks 5, which can be disassembled and used as toys, developing functions other than storage for the packaging box, making it interesting while increasing the additional attribute of the packaging box being able to be used twice, and the remaining part of the packaging box after the splicing blocks 5 are removed can still be recycled, and the packaging box can continue to be used as storage by supplementing the splicing blocks 5 on the box body frame 11 and the cover body frame 21.

[0032] A box body side slot 112 for inserting the box body side panel 12 is arranged on the open end surface of the box body frame 11 facing the cover body frame 21, a bottom plate slot 113 for inserting the box body bottom plate 13 is arranged on the bottom surface of the box body frame 11, a box body hollow structure 115 for displaying the splicing pattern of the box body side panel 12 and a bottom surface hollow structure 116 for displaying the splicing pattern of the box body bottom plate 13 are arranged on the box body frame 11, a cover body side slot for inserting the cover body side panel 22 is arranged on the open end surface of the box body frame 11, a top plate slot for inserting the cover body top plate 23 is arranged on the top surface of the cover body frame 21, and a cover body hollow structure for displaying the splicing pattern of the cover body side panel 22 and a top surface hollow structure for displaying the splicing pattern of the cover body top plate 23 are arranged on the cover body frame 21.

[0033] The detachable connection between the splicing building blocks 5 and the box frame 11 and the cover frame 21 is achieved through the box body side slots 112, the bottom plate slots 113, the cover body side slots and the top plate slots. At the same time, the box body hollow structure 115 and the bottom surface hollow structure 116 on the box body frame 11 can directly touch the box body side panels 12 and the box body bottom plate 13, which is convenient for taking out and storing the box body side panels 12 and the box body bottom plate 13 on the box body frame 11. Similarly, the cover body hollow structure and the top surface hollow structure on the cover body frame 21 also provide convenience for taking out and storing the cover body side panels 22 and the cover body top plate 23.

[0034] In addition, the width dimension of the box body side slot 112 is matched with the thickness dimension of the box body side plate 12, the width dimension of the bottom plate slot 113 is matched with the thickness dimension of the box body bottom plate 13, the width dimension of the cover body side slot is matched with the thickness dimension of the cover body side plate 22, and the width dimension of the top plate slot is matched with the thickness dimension of the top surface of the cover body. Matching means that the thickness dimension of each plate is equal to the width dimension of the corresponding slot, so that the connection of each plate in each slot is tighter, ensuring that the box body side plate 12 and the box body bottom plate 13 are more stably connected to the box body frame 11, and the cover body side plate 22 and the cover body top plate 23 are more stably connected to the cover body frame 21.

[0035] Bottom plate inserts 114 for supporting the bottom plate 13 of the box body are equidistantly arranged on the bottom surface of the box body frame 11, and slot structures for inserting the bottom plate 13 of the box body are formed between the bottom plate inserts 114, and the width of the bottom plate inserts 114 is adapted to the height of the box body side plates 12. Top plate inserts for supporting the top plate 23 of the cover body are equidistantly arranged on the top surface of the cover body frame 21, and slot structures for inserting the top plate 23 of the cover body are formed between the top plate inserts, and the width of the top plate inserts is adapted to the height of the cover body side plates 22.

[0036] The bottom plate insert 114 increases the firmness of the connection between the box body bottom plate 13 and the box body frame 11, and the top plate insert increases the firmness of the connection between the cover body top plate 23 and the cover body frame 21. Figure 3 As shown, when there are four bottom plate inserts 114, corresponding to the number of the box body side panels 12, since the width of the bottom plate inserts 114 matches the width of the box body side panels 12, the splicing pattern of the box body side panels 12 can be matched one by one with the splicing pattern on the bottom plate inserts 114, so after the box body bottom plate 13 and the box body side panels 12 are disassembled, they can be spliced ​​into a complete splicing pattern, which can greatly increase the design sense of the packaging box and the fun of splicing building blocks 5. The same design can also be made on the cover 2.

[0037] An elastic sealing strip 6 for sealing the side panel 12 of the box body is embedded at the opening of the side slot 112 of the box body, and the sum of the height dimension of the elastic sealing strip 6 for sealing the side panel 12 of the box body is greater than the depth dimension of the side slot 112 of the box body. An elastic sealing strip for sealing the side panel 22 of the cover body is embedded at the opening of the side slot of the cover body, and the sum of the height dimension of the elastic sealing strip for sealing the side panel 22 of the cover body is greater than the depth dimension of the side slot of the cover body.

[0038] The design of the elastic sealing strip 6 on the side of the box body and the elastic sealing strip on the side of the cover body allows a buffer strip to be formed in the middle when the cover body 2 is covered on the box body 1. This can reduce the noise when the cover body 2 is covered on the box body 1, and enhance the sealing effect of the packaging box. At the same time, the elastic sealing strip 6 on the side of the box body blocks the outlet of the box body side plate 12, and the elastic sealing strip on the side of the cover body blocks the outlet of the cover body side plate 22. In this way, when the cover body 2 is covered on the box body 1, the box body side plate 12 and the cover body side plate 22 will not be separated, thus ensuring the stability of the box body side plate 12 connected to the box body frame 11, and the stability of the cover body side plate 22 connected to the cover body frame 21.

[0039] A bottom plate elastic sealing strip 7 for sealing the bottom plate 13 of the box body is embedded in the opening of the slot structure formed by the bottom plate insertion strip 114. The sum of the thickness of the bottom plate elastic sealing strip 7 and the length of the bottom plate 13 of the box body is adapted to the depth of the bottom slot structure of the box body frame 11. A top plate elastic sealing strip for sealing the top plate 23 of the cover body is embedded in the opening of the slot structure formed by the top plate insertion strip. The sum of the thickness of the top plate elastic sealing strip and the length of the top plate 23 of the cover body is adapted to the depth of the bottom slot structure of the cover body frame 21.

[0040] The adaptation here means that the sum of the thickness dimension of the bottom plate elastic sealing strip 7 and the length dimension of the box body bottom plate 13 is equal to the depth dimension of the bottom slot structure of the box body frame 11, and the sum of the thickness dimension of the top plate elastic sealing strip and the length dimension of the cover body top plate 23 is equal to the depth dimension of the bottom slot structure of the cover body frame 21. By setting the bottom plate elastic sealing strip 7, the box body bottom plate 13 can be prevented from falling off from the bottom plate insertion strip 114, and by setting the top plate elastic sealing strip, the cover body top plate 23 can be prevented from falling off from the top plate insertion strip.

[0041] Multiple groups of rigid clamping components 14 can also be provided. Providing multiple groups of rigid clamping components 14 can clamp different positions of the article, further enhancing the stability of the article placed in the packaging box.

[0042] The first embodiment of the sliding locking assembly is: it includes a sliding rail 111 located at the bottom of the box body 1 for sliding connection with the support column 141, and an adjusting member 15 connected to the bottom end of the support column 141 for clamping the sliding rail 111, the adjusting member 15 is arranged in an inverted "T" shape, including a horizontal plate 151 and a vertical rod 152, a sliding hole 1111 is arranged in the sliding rail 111 for the vertical rod 152 to pass through, the bottom end of the sliding hole 1111 is connected to a movable cavity for the horizontal plate 151 to slide, a through hole 1411 is arranged on the support column 141 for the vertical rod 152 to pass through, and the sliding locking assembly includes a fastening nut 16 arranged on the end of the vertical rod 152 that passes through the support column 141.

[0043] The second embodiment of the sliding locking assembly is: comprising a slide rail 111 located at the bottom of the box body 1 for sliding connection with the support column 141, and an adjusting member 15 connected to the bottom end of the support column 141 for clamping the slide rail 111, the sliding direction of the adjusting member 15 is the axial direction of the support column 141, the adjusting member 15 is arranged in an inverted "T" shape, and comprises a horizontal plate 151 and a vertical rod 152, and a sliding hole 1111 is arranged in the slide rail 111 for the vertical rod 152 to pass through, and the sliding hole 1111 The bottom end is connected to a movable cavity for the horizontal plate 151 to slide, and a through hole 1411 is provided in the support column 141 for the vertical rod 152 to slide, and the vertical rod 152 passes through the sliding hole 1111 and emerges from the top of the support column 141, and the sliding locking assembly includes a limit member 17 for driving the vertical rod 152 to slide upward and fixing the position of the vertical rod 152. In the process of the limit member 17 driving the vertical rod 152 to slide upward, the horizontal plate 151 can abut against the inner side wall of the slide groove and cooperate with the bottom end of the support column 141 to continuously clamp the slide rail 111, thereby fixing the support column 141 by clamping the slide rail 111.

[0044] The limiting member 17 is sleeved on one end of the vertical rod 152 protruding from the support column 141 and is rotatably connected to the vertical rod 152. A rotating rod 1521 for rotatably connecting the limiting member 17 is convexly provided on the corresponding two side walls of the vertical rod 152. The limiting member 17 is provided with a rotating hole 171 for the rotating rod 1521 to pass through and can drive the limiting member 17 to rotate axially along the rotating rod 1521. The limiting member 17 is arranged in a square structure, and the limiting member 17 is provided with a notch adapted to the outer side wall of the vertical rod 152. During the axial rotation of the limiting member 17 along the rotating rod 1521, it can be flush with the top surface of the support column 141 to limit the vertical rod 152 from sliding downward.

[0045] The limit member 17 uses the lever principle to lift the vertical rod 152, and then rotates to abut against the top surface of the support column 141 to lock the sliding of the vertical rod 152. At this time, the horizontal plate 151 and the bottom end of the support column 141 clamp the slide rail 111, thereby fixing the support column 141. Only when the external force flips the limit member 17 again, the vertical rod 152 can continue to slide.
