Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 4 As shown, this utility model provides a ventilated wooden fire door, comprising:

[0026] Fire door 1;

[0027] Door lock mechanism 2 is located on the left side of the front of the fire door 1;

[0028] The shielding mechanism 3 includes a rotating disk 31, a take-up reel 32 fixedly connected to the back of the rotating disk 31, a pull rope 33 fixedly connected to the surface of the take-up reel 32, a fixing block 34 fixedly connected to the top of the pull rope 33, a lifting plate 35 fixedly connected to the side of the fixing block 34 away from the pull rope 33, a return spring 36 provided at the bottom of the lifting plate 35, and a sealing plate 37 movably connected to the side of the lifting plate 35 away from the fixing block 34.

[0029] refer to Figure 3 The fire door 1 includes a door panel 101. Ventilation windows 102 are provided at the top and bottom of the front of the door panel 101. A sealing plate 37 extends away from the lifting plate 35 and into the interior of the ventilation window 102. The surface of the sealing plate 37 is movably connected to the interior of the ventilation window 102. Hinges 103 are fixedly connected to the top and bottom of the right side of the door panel 101. Sealing strips 104 are fixedly connected to both sides of the inner wall of the ventilation window 102. The inner side of the sealing strip 104 contacts the sealing plate 37. A decorative panel 105 is fixedly connected to the front of the door panel 101. A rotating disc 31 is disposed on the back of the decorative panel 105. The front of the winding disc 32 penetrates the door panel 101 and extends into the interior of the door panel 101. The two sides of the inner wall of the door panel 101 are slidably connected to the lifting plate 35. The sealing plate 37 is located at the top and bottom of the inner cavity of the door panel 101.

[0030] As a technical optimization of this utility model, by setting a fire door 1, fire can be isolated when a fire starts indoors. The user can rotate the door panel 101 through the hinge 103 to close the door panel 101. The door panel 101 and the sealing plate 37 then block the fire indoors and prevent the fire from spreading to the front of the outside.

[0031] refer to Figure 3 The door lock mechanism 2 includes a door lock connecting shell 21, which is located on the left side of the front of the decorative panel 105. The back of the door lock connecting shell 21 penetrates the decorative panel 105 and extends into the interior of the door panel 101. A door latch 22 is movably connected to the left side of the door lock connecting shell 21. A door handle 23 is movably installed on the front of the door lock connecting shell 21. The surface of the door handle 23 is provided with anti-slip texture.

[0032] As a technical optimization of this utility model, by setting a door lock mechanism 2, the door panel 101 can be fixed. When the user closes the door panel 101, he or she turns the door handle 23. The door handle 23 drives the door buckle 22 to be inserted into the door frame through the mechanism inside the door lock connecting shell 21, thereby fixing the door panel 101.

[0033] refer to Figure 2Both ends of the inner side of the sealing plate 37 are fixedly connected with threaded rods 4. The threaded rods 4 pass through the lifting plate 35 and extend to the inner side of the lifting plate 35 on the side near the lifting plate 35. A threaded sleeve 5 is fitted on the surface of the threaded rods 4. A pad 6 is movably connected to the side of the threaded sleeve 5 near the lifting plate 35. The side of the pad 6 near the lifting plate 35 is fixedly connected to the lifting plate 35. The side of the pad 6 near the return spring 36 is fixedly connected to the return spring 36.

[0034] As a technical optimization of this utility model, by setting the threaded rod 4 and the threaded sleeve 5, the sealing plate 37 can be connected to the lifting plate 35 to prevent the sealing plate 37 from shaking on the top of the lifting plate 35.

[0035] refer to Figure 2 The side of the return spring 36 away from the pad 6 is fixedly connected to the fixing plate 7, and the surface of the fixing plate 7 is fixedly connected to the inside of the door panel 101.

[0036] As a technical optimization of this utility model, by setting the fixing plate 7, the bottom of the reset spring 36 can be positioned to prevent the reset spring 36 from moving.

[0037] refer to Figure 2 Both sides of the lifting plate 35 are fixedly connected with sliders 8, and the top and bottom of both sides of the inner wall of the door panel 101 are provided with sliding grooves 9, and the sliders 8 are slidably connected with the sliding grooves 9.

[0038] As a technical optimization of this utility model, by setting the slider 8 and the slide groove 9, the lifting plate 35 can be guided to prevent the lifting plate 35 from deviating when moving.

[0039] refer to Figure 3 A positioning bolt 10 is provided on the right side of the front of the rotating disk 31. The back of the positioning bolt 10 passes through the rotating disk 31 and extends into the interior of the decorative panel 105.

[0040] As a technical optimization of this utility model, by setting the positioning bolt 10, the rotating disk 31 can be fixed to prevent the rotating disk 31 from rotating when it is not needed.

[0041] The working principle and usage process of this utility model are as follows: When in use, the child user closes the door panel 101, then turns the door handle 23. The door handle 23 drives the door latch 22 to be inserted into the door frame through the mechanism inside the door lock connecting shell 21, thus fixing the door panel 101. Then, the rotating disk 31 is turned, which drives the winding disk 32 to rotate. The winding disk 32 winds up the pull rope 33, which drives the fixing blocks 34 to move closer together. The fixing blocks 34 drive the lifting plate 35 to move inward. The lifting plate 35 drives the sealing plate 37 to move closer together, while compressing the return spring 36. The sealing plate 37 moves closer together and separates from the interior of the ventilation window 102, allowing the indoor air to ventilate with the outdoor air through the ventilation window 102.

[0042] In summary, this well-ventilated wooden fire door, by setting up a shielding mechanism 3, allows ventilation windows 102 to be opened at the central axis of the fire door 1. Indoor air is ventilated with outdoor air through ventilation windows 102. Child users do not need to ask their parents to operate the wooden fire door for ventilation, making it convenient for children to operate. It is suitable for users of all ages and ensures normal use by children.
