Description

Technical Field

[0001] This invention relates to the field of airtight escape doors, and in particular to an airtight escape door for medical operating rooms. Background Technology

[0002] As the core component that isolates the operating room from the external environment, the importance of the operating room door is self-evident. It not only needs to have excellent sealing performance to effectively block the intrusion of various external pollutants, but also to ensure that the clean environment inside the operating room is not disturbed by the outside world.

[0003] However, the airtight doors commonly used in hospitals today have certain limitations. Most airtight door designs lack an independent swing door structure. This single door design has revealed many drawbacks in actual use. For example, in the event of a power outage, airtight doors that rely on electric power may be unable to open properly. In the event of sudden disasters such as fires or earthquakes, the automatic opening device of the airtight door often fails to function properly due to factors such as power supply interruption and building structural deformation, which is not conducive to quickly opening the door for personnel evacuation. In addition, if the power source of the sliding door is damaged due to a malfunction and cannot achieve the automatic opening function, it will greatly reduce the success rate of personnel escape, and may even lead to personnel being unable to escape from the danger zone in a timely and safe manner, thus causing serious safety accidents and posing a huge threat to the lives and property of hospital personnel. Summary of the Invention

[0004] The technical problem to be solved by this invention is:

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an airtight escape door for a medical operating room, comprising...

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] Reference Figures 1-7This embodiment provides an airtight escape door for a medical operating room, including a power beam 1 and a hanger wheel assembly 5. A cover plate 2 is detachably connected to one side of the power beam 1. A hanger 17 is horizontally fixedly connected to the lower part of the power beam 1, and a switch is installed on the hanger 17. An airtight sliding door body 8 is provided at the bottom of the hanger 17, and the airtight sliding door body 8 is suspended from the power beam 1 with a guide rail via the hanger 17. The guide rail has a guide rail groove. The airtight sliding door body 8 and the hanger 17 are connected by two hanger wheel assemblies 5. A power motor 3 is fixedly installed on the inner wall of one side of the power beam 1. A toothed belt 14 is installed on the power motor 3. A driven belt tensioner 6 is installed on the inner side of the toothed belt 14 away from the power motor 3. A controller 4 is fixedly installed on the inner wall of the other side of the power beam 1. The power motor 3 serves as the power source and transmits power to the door body through the toothed belt 14. This transmission method has high efficiency and reliability. The toothed belt 14 can accurately transmit the rotational motion of the power motor 3 and convert it into the linear translational motion of the door body. It can also provide sufficient power to drive the heavy airtight sliding door body 8. The driven belt tensioner 6 can adjust the toothed belt 14. The tension of belt 4 is important because during long-term use of the door, the belt may loosen due to wear or temperature changes, affecting the efficiency of power transmission. The driven belt tensioner 6 can adjust the belt tension in a timely manner to ensure good contact between the belt and the power motor 3 and other transmission components, ensuring stable power transmission, preventing belt slippage, extending the belt's service life, and maintaining the stability of the door's movement. A belt connector 13 is fixedly connected to the bottom of the toothed belt 14 near the driven belt tensioner 6 and between the two hanger wheel assemblies 5. The bottom of the belt connector 13... The belt connector 13 is fixedly connected to the top center of the airtight sliding door body 8. It plays a key role in connecting the toothed belt 14 and the airtight sliding door body 8. It can effectively transmit the power of the toothed belt 14 to the door body, ensuring that the door body can move in the expected direction and speed under the drive of the power motor 3. By setting the belt connector 13 between the two hanger wheel assemblies 5 and at the top center of the door body, the traction force on the door body can be distributed more evenly, avoiding the door body from tilting or twisting due to uneven force during movement, and further improving the stability of the door body's movement.The airtight sliding door 8 is hinged to a swing door 9 on one side. A transparent observation window 16 is fixedly connected to the upper part of one side of the swing door 9, and a swing door handle 15 is fixedly connected to the lower part of the transparent observation window 16. A sliding door handle 12 is fixedly connected to one side of the swing door 9 and the airtight sliding door 8. In special circumstances, such as when a larger opening space is needed or for emergency evacuation, the swing door 9 can be used. The operator holds the swing door handle 15 and manually pushes the swing door 9 to rotate around the hinge point with the airtight sliding door 8, thereby opening the swing door 9. The situation outside the door can be observed in advance through the transparent observation window 16 for safer and more efficient operation. To close the swing door 9, simply push the door in the opposite direction to the closed position. Three [unclear text - possibly referring to a specific type of door] are fixedly connected to both sides of the door opening at the bottom of the power beam 1. The square column assembly 7, and the contact side of the three-sided column assembly 7 with the airtight sliding door body 8 are equipped with sealing rubber. The bottom of the three-sided column assembly 7 is fixedly connected to the anti-sway device 10. The sealing rubber on the contact side of the three-sided column assembly 7 on both sides of the bottom of the power beam 1 and the airtight sliding door body 8 is tightly fitted to ensure the airtightness of the door. The anti-sway device 10 at the bottom of the three-sided column assembly 7 prevents the door from swinging during the closing process and ensures the stable closing state of the door. The guide rail groove on the power beam 1 is rotatably connected to the hanger wheels 55 on the two hanger wheel assemblies 5. The connecting slide 56 is slidably connected to the guide rail on the power beam 1. The bottom of the first connecting piece 51 is fixedly connected to the top of the airtight sliding door body 8. A stop device 11 is fixedly connected inside the power beam 1 near the power motor 3. The power motor 3, the stop device 11 and the switch are all electrically connected to the controller 4.

[0028] Example 2

[0029] Reference Figure 5This embodiment is based on the previous embodiment, but differs in that: the hanger wheel assembly 5 includes a first connector 51, a connecting ring 52, a second connector 53, a connecting pipe 54, a hanger wheel 55, and a connecting slide 56. The first connector 51 has a connecting ring 52 fixedly connected to the upper part of one side. The second connector 53 has a connecting pipe 54 fixedly connected to one side, corresponding to the connecting ring 52, and the connecting pipe 54 is located inside the connecting ring 52. The other side of the connecting pipe 54 passes through one side of the second connector 53 and is fixedly connected to the hanger wheel 55. The side of the hanger wheel 55 away from the connecting pipe 54 has a connecting slide 56 fixedly connected. When the airtight sliding door... When the door 8 needs to move, the power is transmitted to the belt connector 13 via the power motor 3. The belt connector 13 then transmits the force to the hanger wheel assembly 5, which is fixedly connected to the top center of the airtight sliding door 8. In the hanger wheel assembly 5, the force is transmitted from the first connector 51 through the connecting ring 52 and the connecting pipe 54 to the hanger wheel 55. The hanger wheel 55 rotates in the guide groove of the power beam 1, thereby converting the vertical force into the horizontal rolling friction force, enabling the door to move along the guide rail. At the same time, the sliding connection between the connecting slide 56 and the guide rail provides auxiliary support and guidance, ensuring that the door maintains a stable linear motion trajectory during the sliding process.
