[0024] Beneficial effects:

[0025] This utility model's fire hydrant concealed door uses a hinge structure to connect the upper and lower ends of the door frame and the door leaf core, achieving a rotating connection. Compared to the common structure where the door leaf is hinged to the door frame on the side, installation is simpler, door gaps are easier to control, and aesthetics are improved. When open for use, part of the door leaf's weight is transferred to the door frame, preventing damage or deformation to the concealed door hinges and the door frame. The accessory box integrates fire hydrant accessories onto the door leaf, reducing the space occupied by items inside the concealed door, making it neater and simpler. Furthermore, when the concealed door is open and the fire hydrant is in use, one person can retrieve items inside the concealed door while another person retrieves accessories from the door leaf, allowing for simultaneous operation by multiple people, improving efficiency and convenience.

[0033] Please see Figure 1-2 This utility model provides a technical solution: a prefabricated fire hydrant concealed door assembly installation structure, comprising:

[0034] Door outer frame 1;

[0035] Door leaf 3, which is assembled on the outside of the inner cavity 2 of the outer frame 1;

[0036] Door core 4 is integrally formed on the inner side of the door 3;

[0037] The hinge structure is located on one side of the axis of the inner cavity 2 and on the upper and lower end faces of the door core 4. It includes a first base 5 positioned on the upper and lower end faces of the inner cavity 2 and a second base 7 positioned on the upper and lower end faces of the door core 4. A first rotating seat 6 is provided on the first base 5 and a second rotating seat 8 is provided on the second base 7. The end faces of the first rotating seat 6 and the second rotating seat 8 are in contact and rotate relative to each other.

[0038] The outer frame 1 of the door is made of aluminum alloy profile, and the hinge structure is made of stainless steel to improve the structural strength of both, ensure the structural stability of the base layer of the concealed door, and make the corners of the outer frame 1 straighter and more aesthetically pleasing.

[0039] The door leaf 3 includes an inner frame 9 and a decorative panel 10 embedded inside the inner frame 9. The inner frame 9 is made of 0.6mm galvanized steel sheet, and the decorative panel 10 is made of hard-pack board, resin board, ceramic tile, cement board, fireproof board, wood veneer, or rock slab. The decorative panel 10 is fixed to the inner frame 9 with marble adhesive and structural adhesive. This increases the stability of the door leaf, ensures the solidity of the finished door base, and makes it less prone to deformation.

[0040] The edge of the decorative panel 10 is provided with several through holes 11 to achieve impact buffering, stress release, and ventilation of the hidden door, so as to prevent the hidden door from being pushed out due to the pressure difference between the inside and outside of the hidden door, or the service life of the locking structure from being compressed for a long time.

[0041] The door core 4 has an aluminum honeycomb structure, which improves the strength of the door.

[0042] The outer frame 1 of the door is provided with an elastic sealing strip 12 on the inner side of the door leaf 3. The elastic sealing strip 12 is positioned inclined inward or outward around the outer frame 1, and the wedge-shaped surfaces at its ends fit together to achieve a sealing treatment at the joint between the two.

[0043] An accessory box 13 is provided on the inner side of the door leaf core 4. The accessory box 13 integrates fire hydrant accessories onto the door leaf 3, reducing the space occupied by items inside the concealed door, making it neater and simpler. Furthermore, when the concealed door is open and the fire hydrant is in use, one person can retrieve items inside the concealed door while another person retrieves accessories from the door leaf 3, allowing multiple people to operate simultaneously, improving efficiency and convenience. In addition, this design also improves the quality of the door leaf 3, preventing accidental opening.

[0044] The installation process of a prefabricated fire hydrant concealed door assembly structure in this embodiment includes: embedding the outer frame 9 into the wall and installing the elastic sealing strip 12; the second base 7 is bolted to the door core 4, the first rotating seat 6 is connected to the second rotating seat 8, the decorative panel 10 is positioned on the inner frame 9, the assembled structure is moved into the inner cavity 2 of the outer frame 1, and the first base 5 is bolted to the upper and lower end faces of the inner cavity 2 to complete the assembly. Then, the fire hydrant components are installed inside the concealed door and the accessory box 13.

[0045] Its working principle includes: prying open the inner side of the door frame 9 and pulling it outward, so that the door core 4 rotates along the axis of the second rotating seat 8, so that the door 3 opens, and then the fire hydrant and its accessories in the hidden door and accessory box 13 can be retrieved.

[0046] In summary, due to the adoption of the above technical solution, the prefabricated installation structure of the finished fire hydrant concealed door in this embodiment has the following advantages compared with the prior art:

[0047] This utility model's fire hydrant concealed door uses a hinge structure to connect the upper and lower ends of the door frame and the door leaf core, achieving a rotating connection. Compared to the common structure where the door leaf is hinged to the door frame on the side, installation is simpler, door gaps are easier to control, and aesthetics are improved. When open for use, part of the door leaf's weight is transferred to the door frame, preventing damage or deformation to the concealed door hinges and the door frame. The accessory box integrates fire hydrant accessories onto the door leaf, reducing the space occupied by items inside the concealed door, making it neater and simpler. Furthermore, when the concealed door is open and the fire hydrant is in use, one person can retrieve items inside the concealed door while another person retrieves accessories from the door leaf, allowing for simultaneous operation by multiple people, improving efficiency and convenience.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
