Description

Technical Field

[0001] The utility model relates to the technical field of sealing rubber strips, in particular to an inflatable and expandable sealing rubber strip for the door of a micro-pressure oxygen chamber. Background Art

[0002] The door of a hard micro-high-pressure oxygen chamber needs to be pressurized and sealed. By setting a sealing rubber strip at the door opening and using a cylinder to push the door to tightly squeeze the rubber strip at the door opening to achieve preliminary sealing. Subsequently, oxygen is pressurized and filled. When the pressure in the chamber reaches the preset value, the cylinder stops working. At this time, the pressure in the chamber naturally pushes the door to closely fit with the rubber strip to ensure a good sealing effect of the door.

[0003] The sealing design of the door of a micro-high-pressure oxygen chamber has strict requirements for the shape of the door opening to ensure the sealing performance. In view of the fact that the rubber strip will gradually lose its elasticity due to frequent opening and closing during use, and the degree of elastic reduction in different parts may be uneven, which may cause different degrees of deformation, directly affecting the subsequent sealing effect. Therefore, it is particularly important to develop a sealing rubber strip that can quickly adjust the sealing performance and realize convenient replacement and disassembly to meet the scenarios with continuously high requirements for the sealing performance of the door. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an inflatable and expandable sealing rubber strip for the door of a micro-pressure oxygen chamber to solve the problems put forward in the above background art.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model

[0026] Embodiment

[0027] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8As shown in the figure, the utility model provides a technical solution: a micro-pressure oxygen chamber door inflatable expansion sealing strip, including an inflatable expansion sealing strip 1 and a solid sealing strip 2, characterized in that: the inflatable expansion sealing strip 1 and the solid sealing strip 2 are snap-connected. The inflatable expansion sealing strip 1 is composed of a hollow rubber strip part 11 and a quick-release strip 12. On the side of the quick-release strip 12 away from the hollow rubber strip part 11, there are multiple snap-fastening parts 13. On the side of the solid sealing strip 2 close to the quick-release strip 12, a quick-release groove 21 is opened. Inside the quick-release groove 21, close to the snap-fastening parts 13, multiple card slots 22 are correspondingly installed. Inside the hollow rubber strip part 11, there is a push switch 15. On the outside of the hollow rubber strip part 11, an air charging pipe 3 and an exhaust pipe 4 are connected. On the exhaust pipe 4, there is a solenoid valve 7. The solenoid valve 7 and the push switch 15 are electrically connected. One end of the air charging pipe 3 away from the hollow rubber strip part 11 is connected to the output end of an air pump 5. On the other input side of the air pump 5, there is an air inlet 6.

[0028] In this embodiment, the door sealing system adopts an innovative design of a sealing strip combining inflatable expansion and solid. Through the ingenious combination of the quick-release strip 12, the quick-release groove 21, the snap-fastening parts 13 and the card slots 22, the quick installation and replacement of the inflatable expansion sealing strip 1 on the solid sealing strip 2 are realized, greatly improving the convenience and modular level of the device. In addition, the air pump 5 and the air charging pipe 3 are used to quickly inflate the hollow rubber strip part 11. When the door is closed, the hollow rubber strip part 11 is naturally squeezed, thereby triggering the built-in push switch 15. Once the push switch 15 is activated, the solenoid valve 7 is started to release air smoothly, ensuring the tight closing of the door while maintaining the continuous and effective pressing of the inflatable expansion sealing strip 1 on the door, thus optimizing the sealing effect and the door operation efficiency, and quickly adjusting the sealing performance.

[0029] The snap-fastening parts 13 include a triangular snap-fastening part 131 and a hemispherical part 132. The side of the snap-fastening part 13 close to the quick-release strip 12 is set as an inverted triangular snap-fastening part 131, and the side of the snap-fastening part 13 away from the quick-release strip 12 is set as a hemispherical part 132.

[0030] In this embodiment, the snap-fastening parts 13 and the card slots 22 are set in a teardrop shape, which is beneficial to fixing the inflatable expansion sealing strip 1 on the solid sealing strip 2 without affecting its quick-release effect.

[0031] Inside the inner side of the hollow rubber strip part 11, there are multiple support layers 14. On the side of the solid sealing strip 2 away from the inflatable expansion sealing strip 1, a first installation groove 23 and a second installation groove 24 are opened. Inside the first installation groove 23, the air charging pipe 3 and the air pump 5 are arranged. Inside the second installation groove 24, the exhaust pipe 4 and the solenoid valve 7 are arranged.

[0032] In this embodiment, the support layer 14 plays a supporting role to prevent the hollow rubber strip part 2 from collapsing too much. The first installation groove 23 and the second installation groove 24 play a role in installing and placing the air charging pipe 3, the exhaust pipe 4, the air pump 5 and the solenoid valve 7.

[0033] A first protective plate 25 and a second protective plate 26 are respectively installed outside the first installation groove 23 and the second installation groove 24. An air charging pipe notch 27 and an exhaust pipe notch 28 are respectively formed in the inner walls of the first installation groove 23 and the second installation groove 24 close to one side of the inflatable expansion sealing strip 1.

[0034] In this embodiment, the first protective plate 25 and the second protective plate 26 serve to protect the devices installed in the first installation groove 23 and the second installation groove 24, and the air charging pipe notch 27 and the exhaust pipe notch 28 reserve installation spaces for the air charging pipe 3 and the exhaust pipe 4.

[0035] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
