[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0021] Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the utility model, rather than implying that each embodiment of the utility model must have the described feature. In addition, it should be noted that this specification describes many features. Although some features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0022] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments:

[0023] refer to Figure 1-4 A highly flame-retardant wooden heat-insulating fireproof door comprises a door frame 1, the right side of the door frame 1 is fixedly connected to two hinges 2, one side of the two hinges 2 is commonly fixedly connected to a wooden fireproof door 3, the right side of the door frame 1 is fixedly connected to a fixed block 4, the lower end face of the fixed block 4 is rotatably connected to a first rotating rod 5, one end of the first rotating rod 5 is rotatably connected to a second rotating rod 6, one end of the second rotating rod 6 is fixedly connected to a third rotating rod, one end of the third rotating rod passes through the upper end face of a placement box 7 and extends into the placement box 7, a gear 14 is fixedly connected to the surface of the third rotating rod, and a rack 13 is meshingly connected to the surface of the gear 14.

[0024] The wooden fire door 3 is fixedly installed by setting a hinge 2;

[0025] Furthermore, the rack 13 is slidably connected in the placement box 7 , and one end of the rack 13 is fixedly connected to a moving block 16 .

[0026] By providing the rack 13, the spring 15 can be squeezed;

[0027] Furthermore, the other end of the rack 13 is fixedly connected to a partition, the right side of the partition is fixedly connected to a spring 15 , and one end of the spring 15 is fixedly connected to the inner wall of the placement box 7 .

[0028] By setting the spring 15, the rack 13 can be pushed to reset, and then the wooden fire door 3 can be rotated and closed;

[0029] Furthermore, a door leaf frame 11 is provided inside the wooden fire door 3 , and perlite 12 is fixedly connected inside the door leaf frame 11 .

[0030] By setting the perlite 12, heat insulation and fire prevention can be performed;

[0031] Furthermore, the surface of the wooden fire door 3 is provided with fireproof paint, an installation opening is opened in the wooden fire door 3, a fireproof glass window 8 is fixedly connected in the installation opening, handles 9 are fixedly connected on both sides of the wooden fire door 3, and a protective cover is fixedly connected to the surface of the handle 9.

[0032] By setting the fireproof glass window 8, the inside of the door can be observed, which has certain practicality;

[0033] Furthermore, an abutment block 10 is fixedly connected inside the door frame 1 , and a sealing layer is fixedly connected to the right side surface of the abutment block 10 .

[0034] By setting a sealing layer, the door body can be well sealed to prevent smoke and dust from entering and exiting.

[0035] The working principle of the utility model is as follows: the door frame 1 is installed in a specific area. When a fire occurs, the escapee pulls the handle 9 to drive the wooden fire door 3 to flip over and escape outward through the door frame 1. When the wooden fire door 3 flips over, it drives the second rotating rod 6 and the first rotating rod 5 to rotate. The rotation of the second rotating rod 6 drives the gear 14 to rotate, thereby driving the rack 13 to move in the direction of the spring 15. The partition squeezes the spring 15, and the spring 15 contracts. When the escapee releases the handle 9, the spring 15 pushes the partition, driving the rack 13 to move in the direction of the moving block 16, thereby rotating the gear 14. Under the action of the first rotating rod 5 and the second rotating rod 6, the wooden fire door 3 fits the abutment block 10.

[0036] Compared with the prior art, the door will not cause the fire door to be unable to be opened due to motor damage, resulting in people having no escape route and being unable to evacuate the scene quickly.

[0037] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
