Abstract

The utility model discloses a wooden heat-insulating fireproof door, including a wooden shell, a first fireproof cotton board, a second fireproof cotton board, and a hard board. The device is provided with an L-shaped plastic gasket, a limit block, a liquid nitrogen box, a T-shaped connecting pipe, a piston, a contact rod, a limit plate, and a nozzle. In a high-temperature environment, the L-shaped plastic gasket is deformed, the limit block on the top falls, and the low-temperature gas in the liquid nitrogen box rushes out to contact the piston to make the T-shaped connecting pipe unobstructed, and then enters the nozzle and is discharged to achieve cooling and fire extinguishing. The utility model can achieve fire prevention while extinguishing flames. At the same time, a reinforcement component is provided, including an installation box, a moving block, a T-shaped frame, a reinforcement rod, and a screw. When external rescue is carried out, the screw is rotated to make the moving block slide. The moving block slides through the external connecting rod to contact the T-shaped frame and moves horizontally, canceling the cooperation between the clamp and the reinforcement rod, thereby achieving a reduction in the overall strength of the device, and facilitating door-breaking rescue.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] A wooden heat-insulating fireproof door, such as Figure 1-Figure 8 As shown, it includes a wooden shell 1, a fireproof cotton board 1 4, a fireproof cotton board 2 5, and a hard board 6. The fireproof cotton board 1 4, the fireproof cotton board 2 5, and the hard board 6 are all bonded to the inner side wall of the wooden shell 1, the inner wall of the wooden shell 1 is bonded with an L-shaped plastic gasket 3, and a limiting block 7 is placed on the top of the L-shaped plastic gasket 3. The inner side wall of the wooden shell 1 is fixed with a nozzle 2 and a liquid nitrogen box 23 by bolts, and the outer side wall of the liquid nitrogen box 23 is welded with a T-shaped connecting pipe 8, the top of the T-shaped connecting pipe 8 is connected to the nozzle 2, and the outer end of the T-shaped connecting pipe 8 is in contact with the limiting block 7. The inner wall of the T-shaped connecting pipe 8 is slidably connected with a piston 9, and the outer side wall of the piston 9 is welded with a resistance rod 10, and the inner wall of the T-shaped connecting pipe 8 is welded with a limiting plate 11, the limiting plate 11 cooperates with the piston 9, and the other end of the resistance rod 10 is in conflict with the limiting block 7.

[0028] During use, when the outside of the device generates high temperature due to flame, the L-shaped plastic gasket 3 is deformed by the heat, causing the limit block 7 to fall, and then the low-temperature gas in the liquid nitrogen box 23 rushes out and contacts the piston 9, making the T-shaped connecting pipe 8 unobstructed, and then enters the nozzle 2 and is discharged, thereby achieving cooling and fire extinguishing.

[0029] A reinforcing component is provided inside the wooden shell 1, and a mounting groove 12 is provided on the outer side wall of the wooden shell 1. A convex plate 13 is clamped on the inner wall of the mounting groove 12, and a locking bolt 14 is connected between the convex plate 13 and the inner wall of the mounting groove 12 through a thread.

[0030] When the fire outside the wooden shell 1 is large and the wooden shell 1 is damaged, and the outside needs to break the door for rescue, the locking bolt 14 can be rotated to remove the convex plate 13, and the reinforcement component can be removed through the gap of the installation groove 12 to facilitate outside personnel to break the door for rescue.

[0031] Working principle: When in use, when the outside of the device generates high temperature due to the flame, the L-shaped plastic gasket 3 is deformed by the heat, causing the limit block 7 to fall, and then the low-temperature gas in the liquid nitrogen box 23 rushes out and hits the piston 9 to make the T-shaped connecting pipe 8 unobstructed, and then enters the nozzle 2 for discharge, thereby achieving cooling and fire extinguishing. When the fire is large, the wooden shell 1 is damaged. At the same time, when external rescue is required, the locking bolt 14 can be rotated to remove the convex plate 13, and the reinforcement component can be removed through the gap in the installation groove 12, so as to facilitate external personnel to break the door for rescue.

[0032] like Figure 2-Figure 3 As shown, the reinforcement assembly includes a mounting box 22, a moving block 15, a T-shaped frame 18, and a reinforcing rod 20. The T-shaped frame 18 is slidably connected to the inner side wall of the wooden shell 1, and the mounting box 22 is welded to the inner side wall of the hard board 6. The inner wall of the mounting box 22 is slidably connected to the moving block 15, and the inner wall of the mounting box 22 is rotatably connected to a lead screw 17, and a rotating head 16 is welded to the outer wall of the top of the lead screw 17. The lead screw 17 is connected to the moving block 15 through a nut, and the outer side wall of the moving block 15 is rotatably connected to a connecting rod 21, and the other end of the connecting rod 21 is rotatably connected to the T-shaped frame 18. A clamp 19 is welded to the outer side wall of the T-shaped frame 18, and the reinforcing rod 20 cooperates with the clamp 19;

[0033] Working principle: After removing the convex plate 13, the lead screw 17 can be rotated by rotating the head 16 to make the moving block 15 slide. The moving block 15 slides through the external connecting rod 21 to resist the T-frame 18 and move horizontally, eliminating the cooperation between the clamping head 19 and the reinforcing rod 20, thereby reducing the overall strength of the device and facilitating external personnel to break through the door for rescue.

[0034] The above description is only a preferred specific implementation manner 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 within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
