DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 10 As shown, the utility model provides the following technical solutions: a fireproof and heat-insulating wooden door, comprising a door frame 2, a door opening for people to enter and exit is formed on the door frame 2, and a door panel 1 is rotatably connected to the door frame 2, a shielding member 4 is also installed on the door frame 2, the shielding member 4 is located on one side of the door panel 1, and the shielding member 4 includes a shell part and a winding part, the bottom of the shell part is open to form a accommodating cavity, the winding part is rotatably connected to the inside of the accommodating cavity, and a fireproof cloth 46 is wound on the winding part, the free end of the fireproof cloth 46 is fixedly connected to a counterweight plate 49, and a hot melt plate 44 is fixedly connected to the inside of the accommodating cavity.

[0027] Through the above technical scheme, when personnel need to install the device, the door frame member 2 is placed at the required fixed position for fixing. After the door frame member 2 is fixed, the door panel member 1 is supported by the door frame member 2. When personnel need to pass through the door frame member 2, the door panel member 1 is pulled to rotate the door panel member 1 relative to the door frame member 2, thereby exposing the door frame member 2, and the personnel can pass through the door frame member 2. When a fire occurs on one side of the device, as the temperature rises, the hot melt plate 44 will melt, so that the hot melt plate 44 cannot block the accommodating cavity, thereby exposing the fireproof cloth 46 and the counterweight plate 49, and the fireproof cloth 46 is pulled by the counterweight plate 49 falling down, so that the rolled part rotates inside the accommodating cavity, thereby unfolding the fireproof cloth 46, and the fireproof cloth 46 is used to block one side of the device, thereby increasing the fireproof performance of the device.

[0028] In addition, in the present invention, in order to facilitate the automatic closing of the door panel 1, Figure 1-Figure 4 As shown:

[0029] A door closer 3 is rotatably connected between the door frame member 2 and the door panel member 1 .

[0030] Through the above technical solution, when a person pulls the door panel 1 to rotate and open it relative to the door frame 2, the door closer 3 cooperates with the door closer 3 to pull the door panel 1, so that the door panel 1 automatically rotates around the door frame 2 back to its original position.

[0031] Specifically, in one embodiment, regarding the door frame member 2:

[0032] like Figure 1-Figure 6 As shown, the door frame member 2 includes two symmetrically arranged door frames 21 , and a partition plate 22 is fixedly connected between the two door frames 21 .

[0033] Through the above technical solution, when the door frame 2 needs to be fixed, the door frame 21 and the partition plate 22 are engaged with the wall hole, so that the door frame 21 and the partition plate 22 are fixed on the door hole.

[0034] Specifically, in one embodiment, regarding the door panel 1:

[0035] like Figure 1-Figure 5 and Fig. 9 As shown, the door panel 1 includes a door panel body 11, on which a through-type observation slot 13 is opened, inside of which a fireproof glass 14 is fixedly connected, and a handle lock 12 is installed on one side of the door panel body 11, and the handle lock 12 is located on one side of the observation slot 13.

[0036] In this embodiment, when a person needs to pull the door panel body 11, the door panel body 11 is supported by the partition 22. When a person needs to pass through the device, the door panel body 11 is pulled by the handle lock 12 to rotate the door panel body 11 back to its original position, and the observation groove 13 and the fireproof glass 14 cooperate to facilitate the person to observe the other side of the device.

[0037] In addition, in the present invention, regarding the above-mentioned door panel body 11, as Figure 1-Figure 5 and Fig. 9 As shown, the door panel body 11 includes an inner frame 111 , and fireproof perlite boards 112 are arranged on both symmetrical sides of the inner frame 111 , and wooden boards 113 are arranged on the opposite sides of the two fireproof perlite boards 112 .

[0038] In this embodiment, the fireproof and heat-insulating performance of the device is improved by the cooperation of the inner skeleton 111, the fireproof perlite board 112 and the wooden board 113.

[0039] In addition, how the shielding member 4 shields the fire source, such as Figure 4-Figure 9As shown, the shielding member 4 includes an outer shell 42, a hollow storage chamber 47 is formed inside the outer shell 42, and the bottom of the outer shell 42 is open to form a bottom hole 41, the bottom hole 41 is connected to the storage chamber 47, and a winding roller 48 is rotatably connected to the inside of the storage chamber 47, and the circumferential surface of the winding roller 48 is sunken to form a winding groove 45, and the fireproof cloth 46 is wound on the winding groove 45, and a hot melt plate 44 is fixedly connected to the inside of the bottom hole 41.

[0040] In this embodiment, the fireproof cloth 46 is rolled up by the winding groove 45 on the winding roller 48. When the hot melt plate 44 melts, it falls down through the counterweight plate 49, thereby pulling the fireproof cloth 46, causing the winding roller 48 to rotate, and allowing the fireproof cloth 46 to block the flame on one side of the device.

[0041] When the shielding member 4 is triggered, in order to facilitate the replacement of the shielding member 4, as Figure 2-Figure 8 As shown, both symmetrical sides of the housing 42 are recessed to form a card slot 43, and a card rod 23 matching the card slot 43 is fixedly connected to the inner wall of the partition 22, and the card rod 23 is detachably connected to the card slot 43.

[0042] In this embodiment, when personnel need to fix the shell 42, the shell 42 is connected to the card rod 23 through the card slot 43 to complete the connection of the device. When the device needs to be disassembled, the shell 42 can be removed by simply pulling the shell 42 to separate the shell 42 from the card rod 23.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
