[0018] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Reference Figure 1 An embodiment of the present application discloses a geometric modular protection structure, which includes a buffer module 11 and a plurality of triangular protection modules 12. The buffer module 11 is used to buffer the external impact force in the stacking direction of the plurality of triangular protection modules 12, and the buffer module 11 is installed at the bottom of the external packaging box.

[0020] Reference Figure 2 , Figure 3 and Figure 4 , the triangle protection module 12 includes: There are three side panels 2 and they are formed by folding a page of cardboard in sequence. In the specific setting, the three side panels 2 can be equal in length, or only two side panels 2 can be equal in length. For the special-shaped disc-like object 7, the three side panels 2 can also be different, which can be selected according to actual needs. In the present embodiment, the three side panels 2 are set to be equal in length; a fixing opening 21 for the edge of the disc-like object 7 to be embedded is opened through the surface of the side panel 2, and the fixing opening 21 can be an arc-shaped groove adapted to the edge of the disc-like object 7; a plurality of slots 22 are opened on one side of the side panel 2, and a plurality of slits 23 are opened on the other opposite side, and the slots 22 are plugged and adapted to the slits 23.

[0021] The tongue seat 31 is integrally formed at the end of the side plate 2 at the side, and a slot 32 is formed through the bend between the tongue seat 31 and the side plate 2. The inserting tongue 33 is integrally formed at the end of the other side plate 2 located at the side, and the inserting tongue 33 is inserted and fitted into the slot 32 .

[0022] When the tongue 33 is inserted and connected with the slot 32 , the three side panels 2 form a triangle; and when two adjacent triangular protection modules 12 are stacked, the tip of one triangular protection module 12 corresponds to the side panel 2 of the other triangular protection module 12 .

[0023] Among them, refer to Figure 4 and Figure 5 The slot 22 is a V-shaped groove to facilitate mutual insertion into the slot 22; there is a gap between the closed ends of the slot 22 and the slit 23 and the adjacent parts of the fixing port 21, so that after multiple triangular protection modules 12 are stacked, the disc-like object 7 inserted in the fixing port 21 will not directly contact with other triangular protection modules 12, so as to prevent external impact force from being transmitted to the protected disc-like object 7 through other triangular protection modules 12.

[0024] The width of the connection between the tongue 33 and the side plate 2 is no greater than the length of the slot 32, and the maximum width of the tongue 33 is greater than the length of the slot 32. Specifically, both sides of the tongue 33 have tongue wings 331. When the tongue 33 is inserted into the slot 32, the two tongue wings 331 are folded inward first, so that the tongue 33 as a whole can freely pass through the slot 32; when the tongue 33 completely passes through the slot 32, the two tongue wings 331 are unfolded, and at this time, the tongue 33 forms a stable connection with the tongue seat 31, which can ensure the structural stability of the triangular protection module 12.

[0025] Therefore, when the tray-type object 7 is packaged by the present application, reference is made to Figure 4 and Figure 5 First, the disk 7 is inserted into the three fixing openings 21 on the three side plates 2 for positioning, and then the tongue 33 is inserted into the slot 32 and adjusted to shape so that the disk 7 is stably embedded in the triangular protection module 12; then refer to Figure 6 When stacking a plurality of triangular protection modules 12 with disc-shaped objects 7 embedded therein, the upper and lower adjacent triangular protection modules 12 are mutually plugged through the plurality of slots 22 and the plurality of slits 23, which can not only improve the stability of the stacked triangular protection modules 12, but also effectively limit the lateral displacement between two adjacent triangular protection modules 12. After the stacking of the plurality of triangular protection modules 12 is completed, the plurality of triangular protection modules 12 are then placed together on the buffer module 11 in the external packaging box.

[0026] When the outer packaging box is subjected to horizontal impact during transportation, on the one hand, the triangular protection module 12 has a unique structural stability of the triangular structure, and has extremely strong anti-deformation and anti-impact effects compared to conventional polygonal protection structures; secondly, the triangular protection module 12 made of corrugated cardboard can also respond to the impact through appropriate deformation when it is subjected to impact, so as to reduce the direct impact on the disc-shaped object 7 inside the triangular protection module 12 and improve the protection effect.

[0027] Moreover, as the number of stacked layers of the triangular protection modules 12 increases, the three tips of the triangular protection modules 12 are continuously superimposed in multiple directions, which greatly enhances the stability of the overall structure of the multiple triangular protection modules 12, and greatly improves the multi-directional and impact resistance performance of horizontal impact. That is, the more the number of protected parts, the stronger the horizontal impact protection effect of the present application. Compared with the current situation in the prior art that "the more the number of protected parts, the worse the protection effect of the packaging structure", the present application goes the other way, uses less packaging materials, and has more obvious advantages.

[0028] In addition, to make it possible to use protective packaging for discs of different sizes, refer to Figure 7 The two slots 22 and the two slits 23 on the side plate 2 form a group for stacking and inserting the adjacent two side plates 2 of other triangular protection modules 12. The side plate 2 is provided with multiple groups of slots 22 and multiple groups of slits 23 for stacking and inserting triangular protection modules 12 of different sizes. In this way, disc-shaped objects 7 of different sizes can be packaged in the same packaging box at the same time.

[0029] Moreover, in the specific configuration, the two slits 23 and two slots 22 in the same group can be located on both sides of the midline of the side panel 2 in the length direction, or on the same side of the midline of the side panel 2 in the length direction; and in the multiple triangular protection modules 12 stacked in sequence, the positions of the slots 22 and slits 23 on the side panels 2 can be arranged opposite each other or staggered, so that the tips of the multiple triangular protection modules 12 are all in different positions, which can further improve the multi-directional resistance to horizontal impact on the horizontal plane of the protection structure of the present application.

[0030] In addition, refer to Figure 8 and Fig. 9 , the above-mentioned buffer module 11 comprises: A rectangular top plate 41 and two trapezoidal top plates 51, the two trapezoidal top plates 51 are arranged at both ends of the rectangular top plate 41 and the three are sequentially connected, and the rectangular top plate 41 and the two trapezoidal top plates 51 form a triangle with a hollow area in the middle; The first oblique support plate 42 is connected to the lower end surface of the rectangular top plate 41 away from the hollow area and extends in an inclined shape toward the hollow area; The second oblique support plate 52 is connected to the lower end surface of the trapezoidal top plate 51 away from the hollow area and extends in an inclined shape toward the hollow area; A first bottom plate 43 is connected to a side of the first oblique support plate 42 away from the rectangular top plate 41 and is arranged parallel to the rectangular top plate 41; and The second bottom plate 53 is connected to a side of the second oblique supporting plate 52 away from the trapezoidal top plate 51 , and is disposed parallel to the trapezoidal top plate 51 .

[0031] A first vertical plate 61 perpendicular to the two trapezoidal top plates 51 is connected between the two trapezoidal top plates 51, and a second vertical plate 62 perpendicular to the trapezoidal top plate 51 and the rectangular top plate 41 is connected between the two trapezoidal top plates 51. The lower end surfaces of the first vertical plate 61 and the second vertical plate 62 are in contact with the corresponding upper end surfaces of the first bottom plate 43 and the second bottom plate 53. Specifically, the lower end surface of the first vertical plate 61 is in contact with the two second bottom plates 53, and the lower end surface of the second vertical plate 62 is in contact with the first bottom plate 43 and the second bottom plate 53.

[0032] The first bottom plate 43 and the extension lines of the side lines of the two second bottom plates 53 away from the hollow area together enclose a closed load-bearing rectangle. Specifically, the projection of the buffer module 11 on the horizontal plane forms the load-bearing rectangle, so that the buffer module 11 can be accurately embedded in the packaging box, and the projection surface of the triangular protection module 12 on the buffer module 11 does not exceed the load-bearing rectangle. The first vertical plate 61 and the second vertical plate 62 are used to fit or bond with the inner side wall of the packaging box, and the first bottom plate 43 and the second bottom plate 53 are used to bond with the inner bottom wall of the packaging box.

[0033] In this way, before packaging the disc-type object 7, the buffer module 11 is placed on the inner bottom wall of the packaging box, the first bottom plate 43 and the two second bottom plates 53 on the buffer module 11 are bonded to the inner bottom wall of the packaging box, and the first vertical plate 61 and the two second vertical plates 62 are fitted with the inner side wall of the packaging box. At this time, due to the arrangement of the first oblique support plate 42 and the two second oblique support plates 52, when a vertical impact occurs, the rectangular top plate 41 and the two trapezoidal top plates 51 of the buffer module 11 serve as the main load-bearing surfaces, which will directly disperse the vertical force to the entire structure of the buffer module 11. Specifically, the first oblique support plate 42 and the two second oblique support plates 52 play a role of oblique support, which converts the impact force in the vertical direction into oblique stress along their own inclined posture, and transmits it to the first bottom plate 43 and the two second bottom plates 53. The first bottom plate 43 and the two second bottom plates 53 serve as bottom supports. On the one hand, they transfer the vertical component of the oblique stress to the ground or other supporting surfaces. On the other hand, they transfer the horizontal component to the surface of the bottom plate of the express box by bonding with the bottom plate of the packaging box. Moreover, the vertically arranged first vertical plate 61 and the two second vertical plates 62 further enhance the stability of the buffer module 11 in the vertical direction. Therefore, when the stacked multiple triangular protection modules 12 are placed on the buffer module 11, the buffer module 11 can not only play a good bearing performance, but also buffer the impact force in the vertical direction, further improving the protection effect on the disc-like object 7, so that the protective structure of the present application can effectively disperse and absorb energy when responding to impacts in different directions, thereby protecting the internal disc-like object 7 from damage.

[0034] Furthermore, the above-mentioned triangular protection module 12 and buffer module 11 are both cut in one piece from E-type or B-type three-layer corrugated cardboard with a gram weight of not less than 250g / m².

[0035] The implementation principle of a geometric modular protection structure in the embodiment of the present application is: When the disc-like object 7 is packaged through the present application, the disc-like object 7 is first embedded in the three fixing openings 21 on the three three side panels 2 for positioning, and then the tongue 33 is inserted into the slot 32 and adjusted to shape, so that the disc-like object 7 is stably embedded in the triangular protection module 12; then, when stacking a plurality of triangular protection modules 12 embedded with the disc-like object 7, the upper and lower adjacent triangular protection modules 12 are mutually plugged through a plurality of slots 22 and a plurality of slits 23, which can not only improve the stability of the plurality of triangular protection modules 12 after stacking, but also effectively limit the lateral displacement between two adjacent triangular protection modules 12. When multiple triangular protection modules 12 are stacked, the multiple triangular protection modules 12 are placed together on the buffer module 11 in the external packaging box. The first oblique support plate 42 and the two second oblique support plates 52 in the buffer module 11 play a role of oblique support, and convert the impact force in the vertical direction into oblique stress along its own inclined posture, and transmit it to the first bottom plate 43 and the two second bottom plates 53, which can effectively disperse and absorb energy, so that the buffer module 11 can not only have good load-bearing performance, but also buffer the impact force in the vertical direction.

[0036] When the outer packaging box is subjected to horizontal impact during transportation, on the one hand, the triangular protection module 12 has a unique structural stability of the triangular structure, and has extremely strong anti-deformation and anti-impact effects compared to conventional polygonal protection structures; secondly, the triangular protection module 12 made of corrugated cardboard can also respond to the impact through appropriate deformation when it is subjected to impact, so as to reduce the direct impact on the disc-shaped object 7 inside the triangular protection module 12 and improve the protection effect.

[0037] Moreover, as the number of stacked layers of the triangular protection modules 12 increases, the three tips of the triangular protection modules 12 are continuously superimposed in multiple directions, which greatly enhances the stability of the overall structure of the multiple triangular protection modules 12, and greatly improves the multi-directional and impact resistance performance of horizontal impact. That is, the more the number of protected parts, the stronger the horizontal impact protection effect of the present application. Compared with the current situation in the prior art that "the more the number of protected parts, the worse the protection effect of the packaging structure", the present application goes the other way, uses less packaging materials, and has more obvious advantages.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
