[0024] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The function of the drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it should not be construed as a limitation on the protection scope of the present utility model.

[0025] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , in an embodiment of a detachable steel-wood fire door of the present utility model, it includes two steel frames 1 both arranged in a "[" shape structure. The two steel frames 1 are parallel to each other and are tightly connected through the arranged connection components. A wood door panel 4 is embedded between the two steel frames 1. The wood door panel 4 is made of high-quality wood, ensuring the overall strength of the fire door. Positioning parts 6 are fixedly connected to both ends of the two steel frames 1. In order to achieve rapid and stable connection, each two adjacent positioning parts 6 are jointly inserted with a connector 2, and the two connectors 2 are detachably connected to the corresponding positioning parts 6 through four equally spaced and symmetrically arranged connection components;

[0026] The connecting component includes a connecting portion 7 fixedly connected to the side of the positioning portion 6, a connecting groove 8 formed inside the connecting member 2 and matingly inserted with the connecting portion 7, positioning grooves 9 formed inside the connecting portion 7 and the connecting member 2, a connecting plate 10, protruding portions 13 fixedly connected to both ends of the connecting plate 10, and a bolt 11 threadedly connected to the center of the connecting plate 10. There are four positioning grooves 9, which are symmetrically formed inside the connecting portion 7 and the connecting member 2 respectively. Every two adjacent positioning grooves 9 are matingly inserted with the corresponding protruding portions 13. One end of the bolt 11 close to the connecting portion 7 is threadedly connected to the connecting portion 7.

[0027] The two protruding portions 13 are accurately inserted into the corresponding positioning grooves 9, realizing a tight connection between the connecting plate 10, the connecting portion 7 and the connecting member 2. By tightening the bolt 11 at the center of the connecting plate 10, a tight fixed connection is formed between the connecting plate 10, the connecting portion 7 and the connecting member 2, thereby completing the fixed connection work of the connecting member 2 and the positioning portion 6. The connection work is simple, and the connecting member 2 is movably connected to the steel frame 1, which facilitates the disassembly of the connecting member 2 to realize the disassembly of the overall structure of the fire door, so as to facilitate the disassembly and replacement of the components that need to be replaced, reducing the maintenance cost and difficulty of the fire door, and having strong practicability.

[0028] Refer to Figure 5 In order to further improve the fire resistance performance of the fire door, two steel protection plates 3 are also embedded between the two steel frames 1. The wooden door panel 4 is clamped between the two protection plates 3, playing a role of clamping and protection. Fireproof materials are coated on the outer sides of the steel frame 1 and the protection plates 3. High-performance fireproof materials are coated on the outer sides of the steel frame 1 and the protection plates 3, which can effectively prevent the spread of fire and ensure the safety of the fire door in case of fire. The fireproof material can be thick-type steel structure fireproof coating, which can form a relatively thick fire-resistant and heat-insulating layer to provide fire protection.

[0029] Refer to Figure 4 In order to ensure the stability of the connection and simplify the manufacturing process, the positioning portion 6 and the steel frame 1 are integrally formed. The outer surface of the connecting member 2 is flush with the outer surface of the steel frame 1. The side of the connecting plate 10 away from the protruding portion 13 is flush with the surface of the connecting member 2. The surfaces of the connecting member 2, the steel frame 1 and the connecting plate 10 are flush, enhancing the integrity and aesthetics of the fire door. Moreover, a counterbore 12 is formed inside the connecting plate 10, and the head of the bolt 11 is located inside the counterbore 12, which not only hides the head of the bolt 11 but also avoids the inconvenience or harm caused to the user due to the protrusion of the head of the bolt 11.

[0030] Refer to Figure 5, on one side where the two protective plates 3 are separated from each other, there are sealing rings 5 in contact with the inner surface of the steel frame 1. The sealing rings 5 are made of high-temperature resistant materials, which can effectively prevent smoke, flames or hot air from penetrating through the gaps between the wooden door panel 4 and the steel frame 1, thereby improving the sealing performance and fire resistance of the fire door. The sealing rings 5 are made of high-temperature resistant materials and can be made of fluorine rubber, which has good high-temperature resistance.

[0031] Working principle: The two protruding parts 13 are accurately inserted into the corresponding positioning grooves 9, realizing the tight connection between the connecting plate 10, the connecting part 7 and the connecting piece 2. By tightening the bolt 11 at the center of the connecting plate 10, a tight fixed connection is formed between the connecting plate 10, the connecting part 7 and the connecting piece 2, so that the fixed connection work between the connecting piece 2 and the positioning part 6 can be completed. The connection work is simple, and the connecting piece 2 is movably connected to the steel frame 1, which facilitates the disassembly of the connecting piece 2 to realize the disassembly of the overall structure of the fire door, so as to facilitate the disassembly and replacement of the parts that need to be replaced, reducing the maintenance cost and difficulty of the fire door, and having strong practicability.

[0032] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art in the said technical field, various changes can be made without departing from the purpose of the present invention.
