[0022] AsFigure 1 , 2 As shown in Figures 3, 4, 5, and 6, a waterproof, dustproof, corrosion-proof, and fireproof door includes a door frame 1 and a door panel 6 hinged within the door frame 1. The door panel 6 includes a support skeleton 61 for increasing the strength of the door panel 6 and preventing severe deformation of the door panel 6. Fireproof boards 63 with a thickness of 10 mm are bonded to both sides of the support skeleton 61 to meet the requirement that the single-point temperature rise of the fire resistance and heat insulation of the door panel 6 does not exceed 180°C, and the average temperature rise of 5 points does not exceed 140°C. The single-point temperature rise of the fire resistance and heat insulation of the door frame 1 does not exceed 360°C. A galvanized alloy plate 64 with a thickness of 1.5 mm is welded to the outside of the fireproof board 63 to further improve the fire resistance and high-temperature resistance ability. A fireproof and heat-insulating filling layer 62 with a thickness of 48 mm is filled within the support skeleton 61. The fireproof and heat-insulating filling layer 62 is made of 60-70% pearl rock wool and 30-40% high-aluminum cement, which not only improves the strength and weight of the door panel 6 but also improves the fireproof and moisture-proof properties, ensuring that the fire resistance integrity and fire resistance and heat insulation of the fireproof door reach the 2-hour standard, facilitating use in harsh outdoor environments, and meeting the waterproof, dustproof, and fireproof protection requirements for equipment within the cabinet. A fireproof lock 4 is fixed to one side of the door panel 6 away from the hinge end. Two groups of locking mechanisms 5 are symmetrically fixed at both ends of the door frame 1. The locking mechanisms 5 can be installed horizontally or vertically. By using the locking mechanisms 5, the door frame 1 can be firmly fixed to the wall, improving the fixing strength. Three layers of anti-corrosion plastic layers are sprayed on the outside of the galvanized alloy plate 64, and the anti-corrosion grade reaches C5H level, meeting the requirements for use in humid environments such as by the sea.

[0023] The door frame 1 and the door panel 6 are fixed by a number of fireproof hinges 7, facilitating the opening and closing of the door panel 6. A fireproof smoke strip 2 is fixed to one side of the inner wall of the door frame 1, and the fireproof smoke strip 2 contacts the door panel 6 in the closed state. A sealing strip 3 is fixed to the other side of the inner wall of the door frame 1, and the sealing strip 3 contacts the door panel 6 in the closed state. By using the fireproof smoke strip 2 and the sealing strip 3, two sealing systems can be formed to block smoke and water vapor, for outdoor waterproofing, fireproofing, and dustproofing, and reaching the IP55 level.

[0024] The locking mechanism 5 is fixed to the upper and lower ends of both sides of the door frame 1. The locking mechanism 5 includes a bottom plate 501 and an upper box body 505. A protective cover 512 is fixed on the bottom plate 501. A battery 511 is fixed in the protective cover 512 for providing power. A middle partition 502 is fixed above the protective cover 512. Four connecting columns 504 are fixed at the four corners of the edge of the middle partition 502. The upper box body 505 is fixed at the upper end of the connecting column 504. The upper end of the upper box body 505 is open. A push plate 514 is slidably installed in the upper box body 505. At least one limit pin 515 is fixed on the upper surface of the push plate 514. An electric telescopic rod is fixed on the upper surface of the middle partition 502. 507, by controlling the electric telescopic rod 507, the limit pin shaft 515 can be controlled to move in the upper box body 505, so as to push the limit pin shaft 515 into or out of the wall, and realize the rapid installation and removal of the fire door. The push plate 514 is connected to the telescopic shaft of the electric telescopic rod 507 by transmission. The upper surface of the middle partition plate 502 is fixed with a wireless controller 509 electrically connected to the electric telescopic rod 507 and the battery 511. The wireless controller 509 adopts a combination of an STC89C51 single-chip microcomputer and a Bluetooth adapter. The Bluetooth adapter can realize the control of the electric telescopic rod 507 by a mobile phone or a mobile terminal. The door frame 1 is inlaid with The charging socket 517 electrically connected to the battery 511 is embedded therein to facilitate charging. The height of the battery 511 is lower than the height of the protective cover 512 to prevent the battery 511 from being subjected to stress. A waterproof rubber sleeve 503 is fixed to the outside of the protective cover 512 to prevent water vapor from contacting the battery 511. The total height of the limit pin 515 and the push plate 514 is lower than the inner cavity depth of the upper box body 505. A through hole is formed in the center of the lower end surface of the upper box body 505. A push rod 513 with one end fixed to the push plate 514 is slidably installed in the through hole. The other end of the push rod 513 is connected to the extension of the electric telescopic rod 507 through the bearing seat 508. The retractable shafts are fixed together, and the distance between the upper end surface of the bearing seat 508 and the bottom of the upper box body 505 does not exceed the height of the limit pin shaft 515. A contact sensor 516 electrically connected to the wireless controller 509 and the battery 511 is fixed on the upper and lower surfaces of the bottom of the upper box body 505. The model of the contact sensor 516 is CSM5PB. The contact sensor 516 is located on the displacement path of the bearing seat 508. The two contact sensors 516 are used to detect the positions of the bearing seat 508 and the push plate 514. When the corresponding parts are detected to be close, a signal is sent to the wireless controller 509, thereby controlling the telescopic length of the electric telescopic rod 507.

[0025] Two groups of elastic splints 510 are symmetrically fixed on both sides of the middle partition 502. The elastic splints 510 are made of spring steel and are arch bridge shaped. One side of the elastic splint 510 extends 1-3 mm beyond the edge of the middle partition 502. When the locking mechanism 5 is installed, the elastic splint 510 can be against the inner wall of the door frame 1, and the elastic force is used to increase the friction force to prevent the locking mechanism 5 from falling into the door frame 1.

[0026] A number of groups of foldable hook plates 506 are symmetrically formed at the upper edge of the upper box body 505. When installing the locking mechanism 5, the foldable hook plates 506 can be folded so that they are bent 90° and clamped at the end of the door frame, preventing the locking mechanism 5 from continuing to enter the door frame 1 and playing a limiting role.

[0027] The installation method of this product is as follows: As Figure 1 , 2 , shown in Figures 3, 4, 5, and 6, first, a notch is opened at the position on the wall corresponding to the locking mechanism 5, and a hole matching the diameter and depth of the limit pin 515 is opened at the position corresponding to the limit pin 515. Then, the door frame 1 is installed in the corresponding door opening. The electric telescopic rod 507 is controlled to extend through the mobile terminal connecting to the wireless controller 509 to push the limit pin 515 into the corresponding hole to complete the installation of the door frame 1. Then, the door leaf panel 6 is fixed inside the door frame 1 by using the fireproof hinge 7. When the door body needs to be disassembled, only need to connect to the wireless controller 509 again by Bluetooth to control the electric telescopic rod 507 to contract, then the separation of the door frame 1 from the wall can be realized, and then the whole door body can be removed, so that the disassembled door body can be used again.

[0028] By providing a waterproof, dustproof, anticorrosive and fireproof door with good fixing effect, strong fireproof ability, high waterproof and dustproof performance and strong stability, the present invention has a broad market prospect.
