[0002] Traditional wooden crates are widely used for packaging and transporting a wide variety of goods due to their lightness, ease of processing, and environmental friendliness. However, wood's inherent strength is limited, making it difficult to guarantee the safety of items that must withstand high pressure or pose a potential explosion risk. While all-steel crates offer superior strength, they are expensive and heavy, making them difficult to transport and store. Therefore, there is a need to address these technical issues. Summary of the Invention
[0003] The purpose of the embodiments of the present application is to provide an explosion-proof steel-wood composite packaging box to solve the technical problem of poor explosion-proof performance of wooden boxes in the prior art.
[0004] To achieve the above objectives, the technical solution adopted in this application is to provide an explosion-proof steel-wood composite packaging box, comprising:
[0005] A wooden box body having a plurality of side panels for enclosing a receiving cavity, wherein adjacent side panels are arranged at an angle;
[0006] Angle steels are provided in the accommodating cavity in a number corresponding to the angle formed by adjacent side panels, the angle steels having a first extending side and a second extending side arranged at an angle, the angle between the first extending side and the second extending side being adapted to the angle between adjacent side panels so that the first extending side and the second extending side are respectively flatly attached to adjacent side panels of the wooden box;
[0007] The support plates, on two opposite sides, respectively abut against the inner corner vertices of the adjacent angle steels and form an arched shape facing away from the side plates. The number of the support plates corresponds to the number of the side plates and is evenly distributed according to the surrounding direction of the side plates.
[0008] Optionally, a plurality of first fins and a plurality of second fins are formed on the support plate, and the first fins and the second fins are arranged at an angle and intersect to form a plurality of grids;
[0009] All of the first fins and all of the second fins are located in the spacing space between the support plate and the side plate.
[0010] Optionally, one end of the first fin and the second fin away from the support plate are both connected to the side plate.
[0011] Optionally, the first fin and the second fin are both arranged at an angle to the side plate.
[0012] Optionally, the explosion-proof steel-wood composite packaging box further comprises a flame retardant having flame retardant properties;
[0013] The flame retardant is filled in a grid formed by the first fins and the second fins.
[0014] Optionally, adjacent support plates abut against each other.
[0015] Optionally, all of the angle steels are connected to form an integral structure.
[0016] The explosion-proof steel-wood composite packaging box provided by the present application has the following beneficial effects: Compared with the prior art, in the explosion-proof steel-wood composite packaging box provided by the present application, because the angle steel forms a first extended edge and a second extended edge flatly attached to the adjacent side panels of the wooden box body, and because the opposing sides of the support plate each abut the inner corner apex of the adjacent angle steel, forming a shape that arches away from the side panels, the support plate disposed within the wooden box body can absorb most of the explosion energy during the explosion shock wave through the support of the angle steel and its own arched shape, effectively preventing deformation of the wooden box body. This effectively prevents the spread of explosion energy and significantly improves the explosion-proof performance of the steel-wood composite packaging box provided by the present application, far surpassing the prior art.

[0024] See also Figure 1 The explosion-proof steel-wood composite packaging box provided in the embodiment of the present application is now described. The explosion-proof steel-wood composite packaging box includes a wooden box body 100, an angle steel 200 and a support plate 300. Among them:
[0025] The wooden box 100 has several side panels 102 for enclosing a accommodating cavity 101, and the adjacent side panels 102 are set at an angle; a number of angle steels 200 are set in the accommodating cavity 101 and the number corresponds to the angle formed by the adjacent side panels 102, and the angle steel 200 has a first extended edge 201 and a second extended edge 202 set at an angle, and the angle between the first extended edge 201 and the second extended edge 202 is adapted to the angle between the adjacent side panels 102 so that the first extended edge 201 and the second extended edge 202 are respectively flat on the adjacent side panels 102 of the wooden box 100; the support plates 300 are respectively in contact with the top corners of the inner corners of the adjacent angle steels 200 on both sides and form a shape that is arched back to the side panels 102, and the number of support plates 300 corresponds to the number of side panels 102 and is evenly distributed according to the enclosing direction of the side panels 102.
[0026] According to the above structure provided in this embodiment, in the explosion-proof steel-wood composite packaging box of this embodiment, because the angle steel 200 forms the first extended edge 201 and the second extended edge 202 flatly attached to the adjacent side panels 102 of the wooden box body 100, and because the two opposing sides of the support plate 300 each abut the inner corner apex of the adjacent angle steel 200 and form a shape that arches away from the side panels 102, the support plate 300 disposed within the wooden box body 100 can absorb most of the explosion energy during the explosion shock wave through the support of the angle steel 200 and its own arched shape, effectively preventing the wooden box body 100 from deforming. This effectively prevents the spread of explosion energy and significantly improves the explosion-proof performance of the steel-wood composite packaging box of this embodiment, far surpassing the existing technology.
[0027] It should be noted that the support plate 300 in this embodiment can be made of wood. In situations where weight is not a concern, it can also be made of metal materials such as steel or iron. In other embodiments of the present application, the support plate 300 can also be made of a polymer material that is even lighter in weight but has higher structural strength, which can further improve the explosion-proof performance of the steel-wood composite packaging box in this embodiment.
[0028] In another embodiment of the present application, see Figure 1 The support plate 300 is formed with a plurality of parallel first fins 301 and a plurality of parallel second fins 302. The first fins 301 and the second fins 302 are arranged at an angle and intersect to form a plurality of grids. All first fins 301 and all second fins 302 are located within the space between the support plate 300 and the side panel 102. According to the above structure provided in this embodiment, the grid structure formed by the first fins 301 and the second fins 302 can not only serve as a support structure for the support plate 300 and improve the structural strength of the support plate 300, but also can be used to absorb a portion of the explosion impact energy, thereby further improving the explosion-proof performance of the steel-wood composite packaging box in this embodiment.
[0029] In another embodiment of the present application, see Figure 1 The ends of the first fin 301 and the second fin 302 away from the support plate 300 are both connected to the side plate 102. According to the above structure provided in this embodiment, the first fin 301 and the second fin 302 connected to the side plate 102 and the support plate 300 on both sides can not only more effectively improve the structural strength of the support plate 300, but also more fully utilize the buffer space between the side plate 102 and the support plate 300 to absorb more explosion energy, which is conducive to further improving the explosion-proof performance of the steel-wood composite packaging box in this embodiment.
[0030] In another embodiment of the present application, see Figure 1The first fin 301 and the second fin 302 are both arranged at an angle to the side panel 102. According to the above structure provided in this embodiment, the first fin 301 and the second fin 302 arranged at an angle to the side panel 102 can prevent the explosion impact energy from vertically impacting the side panel 102, which can effectively prevent the side panel 102 from deforming and is conducive to further improving the explosion-proof performance of the steel-wood composite packaging box in this embodiment.
[0031] In another embodiment of the present application, see Figure 1 The explosion-proof steel-wood composite packaging box also includes a flame retardant 400, which is filled in the grid formed by the first fins 301 and the second fins 302. According to the structure provided in this embodiment, the flame retardant 400 can effectively prevent the spread of fire in the event of a fire or explosion, further improving the explosion-proof performance of the steel-wood composite packaging box in this embodiment.
[0032] In another embodiment of the present application, see Figure 1 Adjacent support plates 300 abut against each other. According to the above structure provided in this embodiment, adjacent support plates 300 can support each other by abutting against each other, which can further improve the structural strength of the support plates 300 and help further improve the explosion-proof performance of the steel-wood composite packaging box in this embodiment.
[0033] In another embodiment of the present application, see Figure 1 All angle steels 200 are connected to form an integrated structure. According to the above structure provided in this embodiment, the angle steels 200 connected into one body can not only provide a more stable support for the support plate 300, but also cooperate with each other to form a greater combined force, which is conducive to further improving the explosion-proof performance of the steel-wood composite packaging box in this embodiment.
[0034] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
