Description

Technical Field

[0001] This utility model belongs to the field of airtight door technology, and in particular relates to an intelligent airtight door sealing structure. Background Technology

[0002] In today's society, with the continuous advancement of technology and people's increasing demands for living and working environments, airtight doors have been widely used in many fields. Whether in medical operating rooms and laboratories where environmental cleanliness and sealing requirements are extremely high, or in industrial plants and chemical workshops where gas leakage needs to be prevented to ensure safety, or in commercial places and high-end residences where sound insulation and heat insulation effects are emphasized, the performance of airtight doors is directly related to the functionality of the place and the user experience.

[0003] Traditional airtight door sealing structures have many shortcomings. Some traditional airtight doors rely solely on a simple set of rubber strips for sealing. Over long-term use, the sealing performance of this method gradually declines due to the rubber strips being susceptible to wear, aging, and changes in ambient temperature and humidity. This makes it impossible to meet the long-term stable airtight requirements. Moreover, a single set of rubber strip sealing structures cannot provide reliable sealing effects in some complex environmental conditions, such as high pressure, high humidity, or environments with corrosive gases.

[0004] In addition, during the closing and opening of the door, it is easy for the seal to be incomplete. Specifically, the fit between the door leaf and the door frame is not precise enough, leaving large gaps that allow gas to leak easily. In some special places with extremely high airtightness requirements, such as biosafety laboratories and electronic chip manufacturing workshops, even a small gas leak can lead to the spread of harmful microorganisms, threatening the health of laboratory personnel and the safety of the surrounding environment. In electronic chip manufacturing workshops, if dust and impurities in the air enter the workshop through gaps in the airtight door, it may affect the production quality of the chips and cause huge economic losses.

[0005] In conclusion, existing airtight door sealing structures can no longer meet the demands of modern society for high-quality, high-performance airtight doors. Therefore, developing a new type of intelligent airtight door sealing structure to solve the above problems and improve the overall performance and reliability of airtight doors is of great practical significance and market demand. Utility Model Content

[0006] The purpose of this utility model is to provide an intelligent airtight door sealing structure to solve the problems caused by insufficient precision in the fit between the door leaf and the door frame of traditional airtight doors, which leads to poor sealing, and the difficulty in meeting the high-quality and high-performance airtight requirements in complex environments and special places, which may cause safety and quality issues.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: an intelligent airtight door sealing structure, including a door frame and a door leaf that cooperate with each other. The door leaf is rotatably connected to the door frame by a hinge. The door frame includes a door frame body. The inner wall of the door frame body cavity is provided with several sets of grooves. The inner wall of the door frame body is also provided with a storage groove. An inflatable sealing ring is provided in the storage groove. A micro air pump is provided on the front surface of the door frame body. The micro air pump is connected to the inflatable sealing ring through an air pipe. The door leaf includes a door leaf body. The outer wall of the door leaf body is provided with several sets of protrusions that cooperate with the grooves. A rubber sealing ring is provided at each set of protrusions.

[0008] Furthermore, at least two sets of the recesses are provided, and the size of the recesses increases sequentially from the storage slot inwards.

[0009] Furthermore, the storage slot is arranged around the inner wall of the door frame body, and the width and depth of the storage slot are uniform.

[0010] Furthermore, the outer diameter of the inflatable sealing ring is larger than the inner diameter of the storage groove.

[0011] Furthermore, the micro air pump is a DC micro air pump, and the air tube is a flexible rubber tube, one end of which is tightly connected to the air outlet of the micro air pump, and the other end of which is connected to the air inlet of the inflatable sealing ring.

[0012] Furthermore, the shape of the boss perfectly matches the shape of the groove, and the spacing between two adjacent sets of bosses is equal.

[0013] Furthermore, the hinges are made of stainless steel, and at least two sets of hinges are provided, symmetrically distributed at the connection between the door leaf and the door frame. Each hinge is fixed to the door leaf body and the door frame body by four bolts.

[0014] Beneficial effects: This utility model has a reasonable design, simple and stable structure, and strong practicality, and has the following beneficial effects:

[0015] 1. Multiple sealing design to improve airtightness: This airtight door adopts a multiple sealing structure that combines rubber sealing rings and inflatable sealing rings. The protrusions on the main body of the door leaf match the grooves of the main body of the door frame. The rubber sealing rings at the protrusions can initially block gas leakage. At the same time, the inflatable sealing rings set in the storage grooves surrounding the inner wall of the door frame can further fill the gaps under the action of a micro air pump, effectively improving the overall sealing performance of the airtight door and meeting the airtightness requirements in different environments.

[0016] 2. Optimize the groove design to enhance sealing stability: The inner wall of the main cavity of the door frame is equipped with at least two sets of grooves, and the size increases from the storage groove inward. This design makes the fit between the boss and the groove tighter when the door is closed, which can better adapt to pressure in different directions, further enhance the sealing stability, and reduce the possibility of gas leakage.

[0017] 3. Inflatable sealing ring design to adapt to complex environments: The outer diameter of the inflatable sealing ring is larger than the inner diameter of the storage groove. After inflation, it can tightly fit the gap between the door frame and the door leaf, effectively compensating for the sealing problems caused by manufacturing errors or deformation during use. This allows the airtight door to maintain a good sealing effect even under complex environmental conditions such as high pressure, high humidity or corrosive gases.

[0018] 4. Precise fit design ensures sealing accuracy: The shape of the boss and the shape of the groove are perfectly matched, and the distance between two adjacent sets of bosses is equal. This precise design ensures the fit accuracy between the door leaf and the door frame, effectively reducing gaps and preventing gas leakage. At the same time, this design also makes the sealing performance of the airtight door more stable and reliable during long-term use.

[0019] 5. Intelligent control and convenient operation: It adopts a DC micro air pump and a flexible rubber tube connected to the inflatable sealing ring. The micro air pump can easily control the inflation and deflation of the inflatable sealing ring, realizing automated sealing adjustment. This intelligent design not only improves the sealing effect, but also provides users with a more convenient operating experience, meeting the needs of modern intelligence.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1:

[0026] Combination Figure 1-2The intelligent airtight door sealing structure shown includes a door frame 1 and a door leaf 2 that cooperate with each other. These two components work together to lay the foundation for achieving efficient airtightness. The door leaf 2 is rotatably connected to the door frame 1 via a hinge 3. The hinge 3, as a key component for the rotation of the door leaf 2, enables smooth and stable rotation of the door leaf 2 during opening and closing, while also possessing good load-bearing capacity to stably support the weight of the door leaf 2 over a long period. The door frame 1 includes a door frame body 101, which serves as the supporting frame for the entire airtight door. It is made of sturdy and durable high-quality metal materials, such as high-strength aluminum alloy or stainless steel, and undergoes refined processing to achieve good strength and stability. Qualitatively, several sets of grooves 102 are formed on the inner wall of the cavity of the door frame body 101. The position and size of these grooves 102 are precisely calculated and designed to ensure perfect fit with the corresponding parts on the door leaf 2. The inner wall of the grooves 102 is finely polished, and the surface is smooth and flat, which not only improves the fitting accuracy with other parts, but also effectively reduces the possibility of gas leakage. The inner wall of the door frame body 101 is also provided with a storage groove 103. An inflatable sealing ring 104 is provided in the storage groove 103. The inflatable sealing ring 104 is one of the core components to achieve high airtightness. When the inflatable sealing ring 104 is not inflated, it can fit tightly against the storage groove 103. Inside, there will be no loosening or displacement. When a stronger seal is needed, inflation can expand the sealant, tightly filling the gap between the door frame 1 and the door leaf 2, effectively preventing gas leakage. A miniature air pump 105 is installed on the front surface of the door frame body 101. The miniature air pump 105 is a key device for controlling the working state of the inflation sealing ring 104. It adopts an advanced miniaturized design, is small in size but powerful in function, and can work efficiently in a limited space. The miniature air pump 105 is connected to the inflation sealing ring 104 via an air pipe, ensuring smooth gas transmission while preventing gas leakage and ensuring the stable operation of the entire inflation system. The door leaf 2 includes... The door leaf body 201, as the main load-bearing structure of the door leaf 2, is also made of high-quality metal material matching the door frame body 101. It possesses sufficient strength and rigidity to withstand various external forces during daily use. On the outer wall of the door leaf body 201, several sets of protrusions 202 are provided to mate with the grooves 102. The shape, size, and position of these protrusions 202 precisely correspond to the grooves 102 on the door frame body 101, ensuring that when the door leaf 2 is closed, the protrusions 202 can accurately embed into the grooves 102, forming a tight fit. Each set of protrusions 202 is equipped with a rubber sealing ring 203. Made of highly elastic and aging-resistant rubber through a special processing technique, it possesses excellent sealing performance. It fits tightly against the surface of the boss 202. When the boss 202 is embedded in the groove 102, the rubber sealing ring 203 further fills the tiny gap between the boss 202 and the groove 102, forming the first line of defense for sealing.Effectively preventing initial gas leakage, and working together with the inflatable sealing ring 104, it achieves a double sealing effect, greatly improving the overall sealing performance of the airtight door.

[0027] In this embodiment, at least two sets of grooves 102 are provided in the inner wall of the cavity of the door frame body 101. The size of these grooves 102 exhibits a unique variation pattern, that is, they gradually increase in size from the storage groove 103 inward. Specifically, the grooves 102 near the storage groove 103 are relatively small in size. As they extend into the door frame, the subsequent grooves 102 gradually increase in length, width, and depth. With this design, as the protrusion 202 continues to penetrate deeper into the grooves 102 during the closing of the door leaf 2, a progressive sealing structure is formed. This structure can better adapt to the leakage trend of gas under different pressure environments, effectively disperse gas pressure, and make the sealing effect more reliable. In addition, the fit of this design is like a mortise and tenon structure, making the connection between the door leaf 2 and the door frame 1 more compact when closed, and less prone to shaking or displacement, further improving the reliability and durability of the entire airtight door sealing structure.

[0028] In this embodiment, the placement groove 103 is ingeniously designed. It surrounds the inner wall of the door frame body 101, forming a complete and continuous structure. This surrounding layout design allows the inflatable sealing ring 104 to be evenly distributed throughout the entire contact area between the door frame 1 and the door leaf 2 after installation, thus providing an all-round, dead-angle-free sealing effect for the airtight door. The width and depth of the placement groove 103 are uniform. The uniform width design also ensures that the inflatable sealing ring 104 receives the same support force at all positions, avoiding deformation or sealing failure due to uneven local force. The uniform depth design is also crucial. The appropriate depth allows the top of the inflatable sealing ring 104 to maintain an appropriate positional relationship with the inner wall surface of the door frame 1 after installation. It is neither too shallow, which would prevent the inflatable sealing ring 104 from effectively filling the gaps and affecting the sealing effect, nor too deep, which would cause the inflatable sealing ring 104 to be subjected to unnecessary compression during inflation, reducing its service life.

[0029] In this embodiment, the outer diameter of the inflatable sealing ring 104 is intentionally designed to be larger than the inner diameter of the storage slot 103. When the inflatable sealing ring 104 is placed in the storage slot 103, because its outer diameter is larger than the inner diameter of the storage slot 103, the inflatable sealing ring 104 already fits tightly against the inner wall of the storage slot 103 in the uninflated state, forming a preliminary sealing barrier. This tight fit can effectively prevent dust, debris, etc. from entering the storage slot 103 during daily use and affecting the sealing effect. When it is necessary to enhance the sealing performance of the airtight door, air is injected into the inflatable sealing ring 104 through the micro air pump 105. As the gas is continuously injected, the inflatable sealing ring 104 gradually expands. Since its outer diameter is originally larger than the inner diameter of the storage slot 103, during the expansion process, the inflatable sealing ring 104 will further squeeze the inner wall of the storage slot 103 tightly, and at the same time expand into the gap between the door frame 1 and the door leaf 2 until it completely fills these gaps, forming a solid and continuous sealing barrier.

[0030] In this embodiment, the miniature air pump 105 is a DC miniature air pump. This type of air pump is small in size and compact in structure, and does not occupy too much space. Moreover, the DC miniature air pump has extremely low operating noise, which is undoubtedly an important advantage for places with strict requirements for environmental noise, such as hospitals and laboratories. It can ensure that there is no excessive noise interference during the operation of the airtight door. The air tube connecting the miniature air pump 105 and the inflation sealing ring 104 is a flexible rubber tube. This flexible rubber tube has good flexibility and elasticity and can adapt to different installation positions and angle requirements. One end is tightly connected to the air outlet of the miniature air pump 105, and the other end is connected to the air inlet of the inflation sealing ring 104. Similarly, through a precise connection method, the gas can smoothly enter the inflation sealing ring 104, providing a sufficient air source for its inflation and expansion.

[0031] In this embodiment, the shape of the boss 202 perfectly matches the shape of the groove 102, achieving seamless connection. This perfect match not only ensures that the boss 202 and the groove 102 can fit tightly when the door leaf 2 is closed, effectively reducing the channels for gas leakage, but also enhances the connection strength between the door leaf 2 and the door frame 1 to a certain extent, making the entire airtight door more stable when subjected to external forces. At the same time, the spacing between two adjacent sets of bosses 202 is equal, and the evenly distributed bosses 202 can form a uniform blocking force on the gas, avoiding the situation of excessive or insufficient local pressure, thereby further improving the reliability of the seal.

[0032] In this embodiment, the hinges 3 are made of stainless steel because stainless steel has excellent corrosion resistance, high strength and good toughness. At least two sets of hinges are set to avoid damage to the hinges 3 or deformation of the door leaf 2 due to excessive force on a single point. These hinges 3 are symmetrically distributed at the connection between the door leaf 2 and the door frame 1. Each hinge 3 is fixed to the door leaf body 201 and the door frame body 101 by four bolts. The use of four bolts for fixing can provide sufficient fastening force to ensure that the connection between the hinges 3 and the door leaf body 201 and the door frame body 101 is firm and reliable.
