By arranging the draw-out box inside the wooden box and placing a desiccant inside the draw-out box, the interior of the wooden box can be dried to prevent the items inside the wooden box from mildewing, which solves the problem of existing fireproof wooden boxes in actual use. When encountering the rainy season, the air humidity is high and the wood There is no drying facility inside the box, which can easily cause the items stored inside the wooden box to mold, affecting people's storage and bringing inconvenience to people's use; the wood used to make some wooden boxes is soaked in flame retardants to improve its fire retardant properties, but the fire resistance of single-layer wooden boxes is still limited, so some wooden boxes adopt a double-layer structure design, and the outside is equipped with materials with better fire resistance to prepare wooden boxes, but the weight of double-layer wooden boxes is heavy, which increases the workload of handling and transportation. It is difficult to optimize the fire protection and overall packaging weight of some existing wooden boxes. The design structure of the wooden boxes is single. In addition, the internal space of some existing wooden boxes cannot be reasonably utilized, and irregular items are not convenient to stack.

[0004] In view of the above problems, it is urgent to carry out innovative design based on the original wooden box. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1: Please refer to Figure 1-Figure 7 The utility model provides the following technical solutions: a fire-retardant safety wooden box, comprising a metal frame 1 which effectively isolates the spread of fire, an outer flame-retardant plate 2 is fixed around and at the bottom of the metal frame 1, an inner flame-retardant plate 3 is fixed inside the outer flame-retardant plate 2, and both the outer flame-retardant plate 2 and the inner flame-retardant plate 3 are soaked in flame retardant; a limiting strip 4 is fixed in the center of the outer edges of the metal frame 1, and a box cover 5 is installed on the outside of the metal frame 1 through the limiting strip 4; a fire-proof mechanism is arranged on the outside of the metal frame 1 to improve the heat resistance of the wooden box.

[0028] A combination frame 6 is embedded and installed in the metal frame 1, and the combination frame 6 is fixed on the inner flame retardant plate 3 at the bottom.

[0029] The fireproof mechanism comprises a fireproof outer box 7 which is snap-fitted and sleeved outside the metal frame 1 . A side groove 8 is formed on the upper end surface of the fireproof outer box 7 . The fireproof outer box 7 is combined and connected with the limit strip 4 through the side groove 8 .

[0030] An elastic limiting block 9 is fixedly installed in the side groove 8, and the elastic limiting block 9 is elastically engaged with the corner position of the limiting strip 4; the upper and lower sides of the elastic limiting block 9 close to the limiting strip 4 are inclined.

[0031] An outer flame retardant panel 2 and an inner flame retardant panel 3 are installed in combination on the metal frame 1. The double-layer flame retardant panel can effectively isolate the fire. In the event of an external fire, it can prolong the time for the fire to spread to the inside of the box, thereby improving the protection effect of the internal packaged items and improving the safety of wooden box packaging and transportation. The flame retardant effect of the outer flame retardant panel 2 and the inner flame retardant panel 3 is mainly to slow down the flame propagation speed, reduce the combustion temperature, reduce smoke generation and delay the spread of fire. The flame retardant forms a protective layer on the surface of the outer flame retardant panel 2 and the inner flame retardant panel 3 to prevent the flame from directly contacting the wood and cut off the oxygen supply, thereby inhibiting combustion.

[0032] According to the performance of the products transported by wooden boxes, single-layer or double-layer packaging products can be selectively performed. The metal frame 1, the outer flame retardant board 2 and the inner flame retardant board 3 are combined and installed to form the inner layer of the wooden box. When packaging and transporting ordinary products, the products are directly packaged through this part to reduce the weight of transportation. When packaging and transporting flammable and explosive products, the fireproof outer box 7 is installed on the outside of the metal frame 1. The elastic limit block 9 on the fireproof outer box 7 is elastically clamped above the limit bar 4 by the squeezing force of the limit bar 4, thereby quickly limiting the fireproof outer box 7 to be installed on the outside of the metal frame 1. At this time, the wooden box has an inner and outer double-layer structure with strong fire retardant performance, and the safety of the overall packaging and transportation of the wooden box is improved.

[0033] Embodiment 2: Based on Embodiment 1, a layered mechanism is further disclosed, and its specific structure is as follows: a layered mechanism for optimizing the space for placing flammable items is arranged inside the metal frame 1. Four corners of the upper end surface of the combination frame 6 are connected with guide columns 10, and a reinforcing layer plate 11 is slidably sleeved on the guide column 10, and a positioning block 12 is fixedly installed on the lower end surface of the reinforcing layer plate 11; the outer side of the reinforcing layer plate 11 is pressed and fitted with the inner side surfaces of the metal frame 1, the outer flame retardant plate 2 and the inner flame retardant plate 3.

[0034] The positioning block 12 is slidably sleeved on the outside of the guide column 10, and a cylindrical rod 13 is fixedly connected in the positioning block 12. A clamping column 14 is slidably sleeved on the outside of the cylindrical rod 13, and a limiting spring 15 is elastically connected between the clamping column 14 and the cylindrical rod 13; a plurality of clamping grooves 16 are evenly spaced on the outside of the guide column 10, and the clamping column 14 is clamped and connected with the clamping grooves 16.

[0035] According to the number of products packaged and transported in the wooden box, the reinforcing layer 11 can be installed on the outside of the guide column 10, thereby dividing the wooden box into two layers of space and optimizing the internal storage space. When the reinforcing layer 11 is installed on the outside of the guide column 10, its outer side is squeezed and fitted against the inner wall of the metal frame 1 and the inner flame retardant plate 3, further reinforcing the assembly of the inner flame retardant plate 3 and the metal frame 1.

[0036] At the same time, the positioning block 12 under the reinforcement layer 11 can display the position where it is installed outside the guide column 10, and push the reinforcement layer 11 and the positioning block 12 to move to a suitable position outside the guide column 10. The clamping column 14 in the positioning block 12 moves toward the direction close to the guide column 10 under the elastic thrust of the limit spring 15, and the clamping column 14 moves and engages in the clamping groove 16 opened on the outside of the guide column 10. Through the clamping connection between the clamping column 14 and the clamping groove 16, the reinforcement layer 11 can be limited to be installed at a suitable position in the metal frame 1, and the installation operation is very convenient.
