DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.
[0024] Please refer to Figures 1-4 , the present utility model provides a technical solution: a new type of flame-retardant fire door, which includes a door main body 2 and a door frame main body 3. The door frame main body 3 is fixed to the wall 1. The door main body 2 is movably installed on the side of the door frame main body 3 through a hinge 4. The door main body 2 includes a support frame 21. The side of the support frame 21 is fixed to the hinge 4. Connecting blocks 22 are provided at the corners of the support frame 21. A flame-retardant cavity 24 is provided inside the support frame 21. A cover plate 26 is provided on the front side of the support frame 21. The cover plate 26 is connected to the connecting block 22 through bolts 261. A flame-retardant board 25 is installed inside the flame-retardant cavity 24. The flame-retardant board 25 can be replaced by opening the cover plate 26;
[0025] During use, the door frame main body 3 is the support structure of the entire door. The door frame main body 3 is not only firmly fixed to the wall 1, but also connected to the door main body 2 through the hinge 4, ensuring the stability of the door. The hinge 4 is a movable component connecting the door frame main body 3 and the door main body 2, allowing the door main body 2 to rotate horizontally to open and close. The support frame 21 is the main skeleton of the door main body 2. The support frame 21 not only bears the weight of the door body, but also provides space for the creation of the flame-retardant cavity 24 through its structural design. The connecting block 22 fixes the support frame 21 and enhances its structural strength. The connecting block 22 enables the door body to remain stable and not easily deformed when facing high-temperature environments such as fires; The cover plate 26 is connected to the connecting block 22 through bolts 261, forming a closed space for the flame-retardant cavity 24. The detachable design of the cover plate 26 allows users to easily open and access the flame-retardant board 25 without damaging the structure of the door main body 2, thereby realizing the replacement of the flame-retardant material.
[0026] A limit block 31 is fixed inside the door frame main body 3. The limit block 31 inside the door frame main body 3 is used to limit the closing position of the door main body 2, prevent the door from rotating excessively when closing, ensure that the door stops at the correct position, and thus avoid damaging the door frame or the hinge 4.
[0027] An airtight ring 27 is provided on the front side of the support frame 21. The position of the airtight ring 27 corresponds to the position of the limit block 31. The function of the airtight ring 27 is to provide a sealing and buffering effect. When the door is closed to the limit block 31, the airtight ring 27 can effectively prevent the leakage of air or smoke, and at the same time reduce the impact force generated by the closing of the door, prevent the wear of the door body and the door frame, and improve the sealing performance and service life of the door.
[0028] The airtight ring 27 is made of rubber. The rubber material can closely fit the limit block 31 when the door is closed, ensuring airtightness and effectively preventing the leakage of air or smoke.
[0029] A decorative surface layer 23 is provided on the rear side of the support frame 21. A door handle 5 is fixed on the rear side of the decorative surface layer 23. The decorative surface layer 23 provided on the rear side of the support frame 21 not only improves the aesthetics of the door, but also plays a protective role. The door handle 5 fixed on the rear side of the decorative surface layer 23 is located on the non-pushing / pulling surface of the door, which is convenient for users to use when they need to open the door.
[0030] Both the support frame 21 and the connecting block 22 are made of metal. Using metal materials for both the support frame 21 and the connecting block 22 ensures their durability and stability in high-temperature environments.
[0031] As an embodiment of the present utility model: When replacing the flame-retardant board 25 or performing maintenance on the new flame-retardant fire door, first remove the cover plate 26 by removing the bolts 261, exposing the flame-retardant cavity 24 inside the support frame 21; then, the aged or damaged flame-retardant board 25 can be easily taken out, and a new flame-retardant board 25 can be replaced as needed; after the replacement is completed, fix the cover plate 26 back to the support frame 21, and firmly connect it to the connecting block 22 through the bolts 261 to ensure the airtightness of the flame-retardant cavity 24 and the integrity of the overall structure; the entire process does not require major disassembly of the door body 2, which is simple and efficient, ensuring that the flame-retardant function of the fire door can be maintained and upgraded in a timely manner.
[0032] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "including", "comprising" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
[0033] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
