This type of door is often used in situations where emergency closure is required, to prevent the spread of substances, or to ensure the safety of a specific environment. In chemical, laboratory or industrial sites, where there is a possibility of toxic gas leakage, protective airtight doors can be used to quickly isolate the affected area. Protective airtight doors can be used to prevent the spread of liquid leaks, especially when corrosive or harmful chemicals are involved. However, with a lifting device, airtight doors can quickly and accurately seal off the affected area, allowing for rapid response to emergencies.

[0003] Current protective airtight doors are mainly used to seal toxic gases, accumulated water or corrosive liquids in emergency situations. However, in non-emergency situations, people want to keep the indoor and outdoor air flowing. To solve this problem, an innovative protective airtight door design is proposed, which uses a lifting airtight beam device. This design allows the door body to be partially opened by lifting the airtight beam to achieve free circulation of indoor and outdoor air without sealing harmful substances. Utility Model Content

[0021] 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.

[0022] Reference Figure 1-2 , the utility model provides an embodiment: a protective airtight door with a lifting type airtight beam device, including a protective door 1, a hand wheel 2 is rotatably connected inside the protective door 1, a worm 3 is fixedly connected to one end of the hand wheel 2, a fixed plate 4 is fixedly connected to the inner wall of the protective door 1, a transmission shaft 5 is rotatably connected inside the fixed plate 4, a worm gear 6 is fixedly connected to the outer wall of the transmission shaft 5, a transmission assembly is arranged at one end of the transmission shaft 5, the worm gear 6 is meshed with the worm 3, a threaded sleeve 8 is rotatably connected inside the fixed plate 4, an adjusting screw 10 is threadedly connected inside the threaded sleeve 8, a connecting plate 11 is fixedly connected to the lower surface of the adjusting screw 10, a limited position shaft 12 is fixedly connected inside the connecting plate 11, a closed plate 13 is arranged on the outer wall of the limited position shaft 12, and the closed plate 13 is rotatably connected to the bottom of one side of the outer wall of the protective door 1; the transmission assembly includes a bevel gear 7, the bevel gear 7 is fixedly connected to one end of the transmission shaft 5, a bevel gear 2 9 is fixedly connected to the upper surface of the threaded sleeve 8, and the bevel gear 7 is meshed with the bevel gear 2 9;

[0023] Specifically, when the closed plate 13 needs to be lifted, the operator will drive the meshing rotation of the worm 3 and the worm wheel 6 by turning the hand wheel 2. This rotation mechanism allows the transmission shaft 5 to stably rotate inside the fixed plate 4. As the transmission shaft 5 rotates, the bevel gear 1 7 and the bevel gear 2 9 begin to mesh, thereby driving the adjusting screw 10 inside the threaded sleeve 8 to lift. By adjusting the lifting and lowering of the screw 10, the connecting plate 11 can be smoothly raised. At the same time, the limit shaft 12 slides inside the limit block on the upper surface of the closed plate 13 to ensure the stable rotation of the closed plate 13. This design makes the operation more convenient and improves the work efficiency and accuracy of the operation. The coordinated work of this series of mechanical components provides a reliable and efficient solution for the lifting of the closed plate 13.

[0024] Reference Figure 2-3 The upper surface of the fixed plate 4 is fixedly connected with an air pump 14, the output end of the air pump 14 is fixedly connected with a connecting pipe 15, and the input end of the air pump 14 is fixedly connected with a connecting pipe 2 16; the connecting pipe 15 penetrates and extends to one side of the inside of the protective door 1, and the connecting pipe 2 16 penetrates and extends to the other side of the inside of the protective door 1; the outer wall of the connecting pipe 2 16 is fixedly connected with a control valve 17, and one end of the connecting pipe 2 16 is fixedly connected with a suction nozzle 18, and a filter screen is provided at the opening of the suction nozzle 18;

[0025] Specifically, when the protective door 1 is in a completely closed state for use, starting the air pump 14 is a key step. The air pump 14 sucks the toxic gas inside the chamber into the inside of the connecting pipe 2 16 through the suction nozzle 18. This process is very fast and efficient, ensuring that the toxic gas in the chamber can be completely discharged. The connecting pipe 2 16 plays the role of transmitting toxic gas, which connects the chamber and the air pump 14 so that the toxic gas can flow smoothly. Through the transmission of the connecting pipe 2 16, the toxic gas is finally guided to the connecting pipe 1 15 and then discharged into the environment outside the chamber. This process is automatic, without manual operation, and greatly improves work efficiency and safety. In general, when the protective door 1 is in a sealed state for use, the effect of starting the air pump 14 and sucking the toxic gas through the suction nozzle 18, then transmitting through the connecting pipe 2 16, and finally discharging it outside the chamber through the connecting pipe 1 15 is very significant. This system not only ensures the safety of the staff, but also improves work efficiency, and is an indispensable part of the modern workplace.

[0026] Reference Figure 2-3 A water pump 19 is fixedly connected to the bottom of the inner wall of the protective door 1, a transmission pipe 22 is fixedly connected to the output end of the water pump 19, and a transmission pipe 1 20 is fixedly connected to the input end of the water pump 19; a water suction pipe 21 is fixedly connected to one end of the transmission pipe 1 20, and the water suction pipe 21 passes through and extends to the inside of the protective door 1; the transmission pipe 2 22 passes through and extends to one side of the inside of the protective door 1;

[0027] Specifically, when there is accumulated water inside the chamber, the transmission pipe 22 is started so that the accumulated water near the bottom of the protective door 1 is transmitted to the inside of the transmission pipe 1 20 through the suction pipe 21. At this time, the accumulated water is transmitted to the inside of the transmission pipe 2 22 through the transmission pipe 1 20. Through the transmission of the transmission pipe 2 22, the accumulated water is discharged from the chamber, thereby achieving the effect of ensuring people's personal safety.

[0028] Working principle: when the sealed plate 13 needs to be lifted, the hand wheel 2 is turned so that the hand wheel 2 drives the worm 3 to mesh with the worm wheel 6 and rotates. At this time, the worm wheel 6 drives the transmission shaft 5 to rotate stably inside the fixed plate 4. At this time, the transmission shaft 5 drives the bevel gear 1 7 to mesh with the bevel gear 2 9 and rotates, so as to facilitate the lifting of the adjusting screw rod 10 inside the threaded sleeve 8. By adjusting the lifting and lowering of the screw rod 10, the connecting plate 11 is driven to rise. The limiting shaft 12 slides inside the limiting block on the upper surface of the sealed plate 13, so as to drive the sealed plate 13 to rotate. When the protective door 1 is in a sealed state, When it is used in the state, by starting the air pump 14, the toxic gas inside the secret room is sucked into the connecting pipe 16 through the suction nozzle 18, and then transmitted through the connecting pipe 16, so as to achieve the effect of discharging the toxic gas outside the secret room through the connecting pipe 15. When there is accumulated water inside the secret room, by starting the transmission pipe 22, the accumulated water near the bottom of the protective door 1 is transmitted to the transmission pipe 1 20 through the suction pipe 21. At this time, the accumulated water is transmitted to the transmission pipe 2 22 through the transmission pipe 1 20, and the accumulated water is discharged from the secret room through the transmission of the transmission pipe 22, thereby achieving the effect of ensuring people's personal safety.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
