DETAILED DESCRIPTION

[0024] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0025] like Figure 1-Figure 6 As shown, the fireproof and flame-retardant wooden door provided in this embodiment includes a door frame 1 and a wooden door body rotatably installed on the inner side of the door frame 1, the wooden door body includes a fireproof and flame-retardant panel 2 and a heat insulation panel 9 fixedly installed on the inner side of the fireproof and flame-retardant panel 2, a support frame 5 is fixedly installed on the inner side of the heat insulation panel 9, a protective plate 3 fixedly installed on the heat insulation panel 9 is provided on the inner side of the support frame 5, four mutually perpendicular sealing mechanisms 6 are rotatably installed on the inner wall of the support frame 5, a plurality of evenly distributed second grooves 12 are opened on the front side of the support frame 5, one end of the second groove 12 is connected to the sealing mechanism 6, and a trigger mechanism 10 penetrating the heat insulation panel 9 and the fireproof and flame-retardant panel 2 is connected to the sealing mechanism 6. Through the arrangement of the sealing mechanism 6, the rebound mechanism 11 and the trigger mechanism 10, when a fire occurs outside, the trigger mechanism 10 is heated and then the fixation of the sealing mechanism 6 is loosened. At this time, the rebound mechanism 11 will be tightened, thereby driving the sealing mechanism 6 to seal the joint between the support frame 5 and the door frame 1, thereby preventing external smoke from entering the room, thereby effectively ensuring the life safety of indoor personnel.

[0026] The protective plate 3 is rotatably provided with side plates 4 for shielding the sealing mechanism 6 by hinges. The side plates 4 can conveniently shield the sealing mechanism 6 in daily use to prevent the sealing mechanism 6 from being directly exposed to the outside, and the side plates 4 are not fixed, so when the sealing mechanism 6 pops out, the side plates 4 can be directly pushed open.

[0027] A locking mechanism 8 is provided between the protective plate 3 and the door frame 1. The locking mechanism 8 includes a first plug block 801 fixedly installed on the inner side of the door frame 1, a second plug block 802 fixedly installed on the front side of the protective plate 3, an insertion rod 803 movably installed between the first plug block 801 and the second plug block 802, and through holes are provided on the first plug block 801 and the second plug block 802 to cooperate with the insertion rod 803. Through the provision of the first plug block 801, the second plug block 802 and the insertion rod 803, the protective plate 3 and the door frame 1 can be connected and fixed.

[0028] The trigger mechanism 10 includes a heat conducting sheet 101 installed on the outside of the fireproof and flame retardant board 2, a heat conducting column 102 penetrating the fireproof and flame retardant board 2 and the heat insulation board 9 is connected to the heat conducting sheet 101, a connecting rope 103 is connected to the end of the heat conducting column 102 away from the heat conducting sheet 101, and a hook 104 is connected to the end of the connecting rope 103 away from the heat conducting column 102. When in use, the first mounting frame 601 and the second mounting frame 602 pulled into the support frame 5 can be fixed by the hook 104. When a fire occurs outside, the heat conducting sheet 101 and the heat conducting column 102 will be heated, and the connecting rope 103 will be melted during the temperature rise, thereby releasing the fixation of the first mounting frame 601 and the second mounting frame 602.

[0029] The sealing mechanism 6 comprises a first mounting frame 601 and a second mounting frame 602 which are symmetrically arranged. The first mounting frame 601 and the second mounting frame 602 are both rotatably mounted on the inner side of the support frame 5 through a mounting seat 603 which is rotatably connected thereto. The first mounting frame 601 and the second mounting frame 602 are connected together with a connecting rod 604 at one end away from the mounting seat 603. A sealing sleeve 605 made of a soft heat-resistant material is sleeved on the outer side of the connecting rod 604. The edges of the support frame 5 which are in contact with the door frame 1 are provided with a first groove 7 which cooperates with the sealing sleeve 605. By setting the arc-shaped first groove 7, the sealing sleeve 605 which is cylindrical in shape as a whole can be used, so that the overall sealing effect is better.

[0030] The rebound mechanism 11 includes a fixing seat 112 fixedly mounted on the inner side of the second groove 12, and a heat-resistant elastic rope 111 for connecting the sealing mechanism 6 is fixedly mounted on the fixing seat 112. When in use, multiple heat-resistant elastic ropes 111 are tied to the first mounting frame 601 and the second mounting frame 602 respectively, and then the first mounting frame 601 and the second mounting frame 602 are rotated to be stored inside the support frame 5, and then the first mounting frame 601 and the second mounting frame 602 are fixed by multiple hooks 104, thereby completing the preparation work before triggering.

[0031] In this embodiment, if Figure 1-Figure 6As shown, the working process of a fire-resistant and flame-retardant wooden door provided in this embodiment is as follows: when a fire occurs outside, the heat conductive plate 101 and the heat conductive column 102 will be heated, and the connecting rope 103 will melt during the temperature rise. At this time, the heat-resistant elastic rope 111 connected to the first mounting frame 601 and the second mounting frame 602 will be reset under its own elastic force, and the first mounting frame 601 and the second mounting frame 602 will be pulled to pull the connecting rod 604 and the sealing sleeve 605 out from the inner side of the supporting frame 5, so that the sealing sleeve 605 is blocked in the first groove 7 at the joint between the supporting frame 5 and the door frame 1, thereby preventing external smoke from entering the room.

[0032] The above description is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and concepts of the present invention within the scope disclosed by the present invention, which belong to the protection scope of the present invention.
