[0042] The arrangement of the connecting clearance gap 1 5, the connecting clearance gap 2 6, the docking clearance gap 1 7, and the docking clearance gap 2 8 can make way for the overlapping and interfering parts.

[0043] As a specific technical solution of this embodiment, refer to Figure 7In the up and down direction and the left and right direction of the multi-size module 1, a connecting platform 13 and a connecting balcony 14, a connecting balcony 2 16 and a connecting platform 2 15 are respectively arranged. Through the overlap of the yin and yang concave platforms, and then through the corresponding connecting holes 4 and waist-shaped holes 11 of the yin and yang concave platforms, they are fixed with bolts or pins. Through the combination of the multi-size module 1 and the waist-shaped holes with stepless size adjustment, a double-layer buffer guard plate is formed. Please refer to Figure 1 , or with the size adjustment module 2, almost all commonly used length and width sizes can be obtained by using fewer module combinations; the waist-shaped hole 11, the waist-shaped hole 28, and the adjustment slide 29 can all be used to adjust the size, which greatly increases the application scenarios of the product.

[0044] As a specific technical solution of the present embodiment, the setting of buffer bulge 17 and buffer bulge 27 is used to increase the buffering performance. Because the bulge is far away from the main body, during the blow molding process, the wall formed at a long distance is thin. In this way, the top of the bulge can form a soft buffer body, and the main body can form a strong support body, thereby achieving an ideal state in which the main body is strong and the buffer part that contacts the product is soft.

[0045] As a specific technical solution of this embodiment, the multi-size module 1 and the size adjustment module 2 are both formed of environmentally friendly tough flame-retardant materials.

The connecting hole 4 between the inner and outer walls can strengthen the wall surface. The strength can be adjusted by adjusting the wall thickness according to the situation of the protected product. Through the above measures, the material can be greatly reduced, the packaging volume can be reduced, and the packaging cost can be saved.

[0047] As a specific technical solution of this embodiment, due to its good strength support and convenient combination mode for changing size, the multi-size module 1 and the size adjustment module 2 can also replace cartons and the like as packaging materials directly, rather than auxiliary packaging materials.

[0048] As a specific technical solution of the present embodiment, the connecting platform 1 13, the connecting platform 2 15, the docking platform 1 23 and the interior of the docking platform are all provided with a plurality of connecting holes 4, and the multi-size module 1, the adjustment plate 1 21 and the adjustment plate 2 22 are all double-wall structures with cavities inside. After the multi-size module 1 and the size adjustment module 2 with double-wall structures are combined into a double-layer buffer guard plate, they can directly replace cartons and the like as packaging materials, and the double-layer buffer guard plate can also be used as a floating bridge on the water surface or a floating board for a water playground because of its cavity inside. Combined with its size-changeable combination mode, the application prospects of the product are greatly increased.

[0049] As a specific technical solution of this embodiment, the number of the multi-size modules 1 and the size adjustment modules 2 are both several, and several of the multi-size modules 1 and the size adjustment modules 2 are combined into a double-layer buffer guard plate. The multi-size modules 1 and the size adjustment modules 2 can be used independently according to the size of the protected product, or they can be combined with each other for use, which can be selected as needed, and the application scenarios are greatly increased.

[0050] As a specific technical solution of this embodiment, the two adjacent transversely combined multi-size modules 1 are connected by connecting the second platform 15 and the second balcony 16, and the connecting hole 4 inside the connecting platform 15 is opposite to the waist-shaped hole 11 inside the connecting balcony 16 and is locked by bolts. At this time, the connecting clearance gap 5 can make way for the common area of ​​the connecting platform 15 and the connecting platform 13. The setting of the waist-shaped hole 11, in conjunction with the connecting hole 4, allows the distance between two transversely adjacent size adjustment modules 2 to be fine-tuned.

[0051] As a specific technical solution of this embodiment, the two adjacent longitudinally combined multi-size modules 1 are connected by snapping together a connecting platform 13 and a connecting balcony 14, and the connecting hole 4 inside the connecting platform 13 is opposite to the waist-shaped hole 11 inside the connecting balcony 14 and is locked by bolts. At this time, the connecting clearance gap 6 can make way for the common area of ​​the connecting platform 13 and the connecting platform 15. The setting of the waist-shaped hole 11, in conjunction with the connecting hole 4, allows the distance between the two longitudinally adjacent size adjustment modules 2 to be fine-tuned.

[0052] As a specific technical solution of this embodiment, the two adjacent longitudinally combined size adjustment modules 2 are connected by snapping together a docking platform 23 and a docking balcony 24, and the connecting hole 4 inside the docking platform 23 is opposite to the waist-shaped hole 28 inside the docking balcony 24 and is locked by bolts. At this time, the docking clearance gap 7 can make way for the common area of ​​the docking platform 23 and the docking balcony 25.

[0053] As a specific technical solution of this embodiment, the adjustment slot 29 is in the shape of a long strip, and the adjustment plate 1 21 and the adjustment plate 2 22 are locked by bolts, and the bolts are located inside the adjustment slot 29. Figure 1 and Figure 4 The long strip-shaped adjustment slot 29 ensures the adjustment range of the relative positions of the adjustment plate 1 21 and the adjustment plate 2 22, and can meet the requirements of double-layer buffer guard plates of different sizes.

[0054] As a specific technical solution of this embodiment, the front and back sides of the multi-size module 1 are provided with a plurality of buffer bulges 17, and the front and back sides of the adjustment plate 1 21 and the adjustment plate 2 22 are provided with a plurality of buffer bulges 27. The setting of the buffer bulge 17 and the buffer bulge 27 is used to increase the buffering performance. Because the bulge is far away from the main body, in the process of blow molding, the wall formed at a long distance is thin, so the top of the bulge can form a soft buffer body, and the main body can form a strong support body, so as to achieve an ideal state in which the main body is strong and the buffer part contacting the product is soft.

[0055] As a specific technical solution of this embodiment, a lifting mouth 12 is provided on the front of the multi-size module 1, and the lifting mouth 12 is one of a concave platform, a convex platform or a through hole. The setting of the lifting mouth 12 and the side wall surface of the lifting mouth 12 can support the inner and outer walls of the multi-size module 1, increase the structural strength of the multi-size module 1, and at the same time reduce the use of processing materials and reduce processing costs.

[0056] As a specific technical solution of this embodiment, the longitudinal edges of the connecting platform 1 13, the connecting platform 2 15, the docking platform 1 23 and the docking platform 2 25 are all provided with water-retaining ribs 3; the water-retaining ribs 3 are arranged so that when several multi-size modules 1 and the size adjustment modules 2 are combined with each other, the water-retaining ribs 3 are mutually clamped at the connection, and the connection is waterproofly sealed, so that water can only flow downward and not flow into the interior.

[0057] In summary, the combined double-layer buffer guard plate is provided with a connecting platform 13 and a connecting balcony 14 as well as a connecting balcony 2 16 and a connecting platform 2 15 in the up and down directions and the left and right directions of the multi-size module 1, respectively. By overlapping the yin and yang concave platforms and fixing them with bolts or pins through the connecting holes 4 and the waist-shaped holes 11 corresponding to the yin and yang concave platforms, a combination of several multi-size modules 1 can be completed, or by matching with the size adjustment module 2, almost all commonly used length and width sizes can be obtained by using a relatively small combination of modules.

[0058] The combined double-layer buffer guard plate, the buffer bulge 17 and the buffer bulge 27 are arranged to increase the buffering performance. Because the bulge is far away from the main body, during the blow molding process, the wall formed at a distant place is thin. In this way, the top of the bulge can form a soft buffer body, and the main body can form a strong supporting body, achieving an ideal state in which the main body is strong and the buffer part that contacts the product is soft.

[0059] The combined double-layer buffer guard plate, the multi-size module 1, the adjustment plate 1 21 and the adjustment plate 2 22 are all double-layer wall structures with a cavity inside. The connecting hole 4 between the inner and outer walls can strengthen the wall surface. The strength can be adjusted by adjusting the wall thickness according to the situation of the protected product. Through the above measures, the material can be greatly reduced, the packaging volume can be reduced, and the packaging cost can be saved.

[0060] The combined double-layer buffer guard plate has good strength support because the multi-size module 1 and the size adjustment module 2 have a combination mode that is convenient for changing the size. The multi-size module 1 and the size adjustment module 2 can also replace cartons and the like as packaging materials directly, rather than auxiliary packaging materials.
