Description

Technical Field

[0001] This utility model relates to the field of sliding door sealing technology, specifically a sealing structure for doors. Background Technology

[0002] Currently, door sealing structures generally use rubber strips. However, after prolonged use, the rubber strips are prone to reduced sealing effectiveness due to pressure or friction. Therefore, there is an urgent need to develop a sealing structure for doors to solve the problems in existing technologies. Utility Model Content

[0003] The purpose of this utility model is to provide a sealing structure for doors that can improve the sealing effect, has a more reasonable sealing method, and is simple in structure and easy to use, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A sealing structure for a door includes a sealing plate and a sliding door. A sealing assembly is provided on the outer wall of the sliding door near the sealing plate. The sealing assembly includes a sealing seat and a sealing ring. A gap for airflow is provided between the sealing ring and the sealing seat. The sealing assembly is rectangular in shape and connected end to end. The sealing seat does not contact the sealing plate. It also includes a pneumatic assembly, which includes an air pipe and an air guide block disposed on the bottom outer wall of the sliding door. The bottom outer wall of the air guide block is provided with an exhaust throttle valve, and the air pipe is connected to the exhaust throttle valve and the gap respectively through the air guide block. A drive assembly is disposed on one outer wall of the sealing plate.

[0005] By adopting the above technical solution, the sealing ring is made of soft material, and the sealing seat is set on the sliding door. Therefore, when it is necessary to seal the gap between the sliding door and the sealing plate, the gap between the sealing ring and the sealing seat is inflated by the pneumatic component. After inflation, the sealing ring gradually bulges up until it slowly contacts the sealing plate. At this time, continuing to inflate will increase the contact area between the sealing ring and the sealing plate, and the sealing ring will stick tightly to the surface of the sealing plate, thereby achieving a sealing effect. When sealing is not needed or the sliding door needs to be moved, the air can be released by controlling the exhaust throttle valve. Compared with the traditional rubber strip seal, this solution can reduce the contact between the sealing ring and the sealing plate, effectively prevent damage caused by hard impacts such as friction and compression, and has a better sealing effect.

[0006] As a further embodiment of this utility model: the gap between the sealing ring and the sealing seat is shaped like a "3" when not inflated, and the gap between the sealing ring and the sealing seat is shaped like a "C" when inflated.

[0007] By adopting the above technical solution, the sealing ring does not contact the sealing plate before sealing. Inflation is only carried out after the sliding door reaches the designated position. At this time, the sealing ring bulges towards the sealing plate, and no lateral friction is generated. At the same time, as the gas gradually fills the gap between the sealing ring and the sealing seat, it will cause soft contact between the sealing ring and the sealing plate. As inflation proceeds, the contact area between the sealing ring and the sealing plate will gradually increase, thus the sealing effect is better.

[0008] As a further embodiment of this utility model: a cable chain is provided on one outer wall of the sealing plate, and the air pipe is disposed in the cable chain.

[0009] As a further embodiment of this utility model: the air pipe has a two-section structure, one section of the air pipe is located in the cable chain and one end of the air pipe is connected to the input end of the exhaust throttle valve, and one end of the other section of the air pipe is connected to the output end of the exhaust throttle valve, and the other end of the other section of the air pipe communicates with the gap of the sealing ring.

[0010] As a further aspect of this utility model: the interior of the air guide block is a hollow structure, and the air guide block is used to guide the airflow from the exhaust throttle valve through the air pipe into the gap of the sealing ring.

[0011] By adopting the above technical solution, cable chains can be used to protect air pipes from damage.

[0012] As a further embodiment of this utility model: the driving assembly includes a mounting plate disposed on the top of one side of the outer wall of the sealing plate and a mounting plate on the top of the top of the sealing plate. A linear slide rail is disposed on the outer wall of the mounting plate near the sealing plate. A driving cylinder is disposed on the top of one side of the outer wall of the sealing plate. The output end of the driving cylinder is connected to the top of the sliding door.

[0013] As a further embodiment of this utility model: sliders are provided at the four corners of one outer wall of the sliding door, and the sliding door forms a sliding fit with the linear slide rail through the sliders.

[0014] By adopting the above technical solution, when the sliding door needs to be moved, the drive cylinder is started to move the sliding door left and right on the linear slide rail. Before moving, the air must be released through the exhaust throttle valve to keep the sealing ring away from the sealing plate. The air is then inflated after the sliding door reaches the designated position.

[0015] As a further embodiment of this utility model: two through holes of the same size and shape are provided on one outer wall of the sealing plate, the coverage area of ​​the sliding door is larger than the area of ​​the through holes, and the area enclosed by the sealing ring is larger than the area of ​​the through holes.

[0016] By adopting the above technical solution, the rectangular area enclosed by the sealing ring must be larger than the through hole on the sealing plate in order to ensure its sealing effect.

[0017] In summary, this application includes at least one of the following beneficial technical effects: 1. Excellent sealing effect. Unlike traditional sealing strips, the sealing method in this solution involves inflating the door after it reaches the designated position. After inflation, the sealing ring bulges and gradually contacts the sealing plate. With further inflation, the contact area between the sealing ring and the sealing plate increases, resulting in a better sealing effect through flexible contact between the sealing ring and the sealing plate.

[0018] 2. The sealing method is more reasonable. The sliding door is inflated only after it reaches the designated position. Before inflation, the sealing ring does not come into contact with the sealing plate, thus avoiding friction and compression of the sealing ring and preventing damage to it. Inflation is performed only after the sliding door reaches the designated position, and the sealing ring and the sealing plate make flexible contact. The door is then deflated before moving. Throughout the entire movement process, the sealing ring will not come into contact with the sealing plate, increasing its service life and making the sealing method more reasonable.

[0019] Other features and advantages of this utility model will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment, a sealing structure for a door includes a sealing plate 1 and a sliding door 2. A sealing assembly is provided on the outer wall of the sliding door 2 near the sealing plate 1. The sealing assembly includes a sealing rubber seat 12 and a sealing rubber ring 5. A gap for airflow is provided between the sealing rubber ring 5 and the sealing rubber seat 12. The sealing assembly is rectangular in shape and connected end to end. The sealing rubber seat 12 does not contact the sealing plate 1. It also includes a pneumatic assembly, which includes an air pipe 11 and an air guide block 10 disposed on the bottom outer wall of the sliding door 2. An exhaust throttle valve 9 is disposed on the bottom outer wall of the air guide block 10. The air pipe 11 is connected to the exhaust throttle valve 9 and the gap through the air guide block 10 respectively. A drive component is disposed on one outer wall of the cover plate 1.

[0024] When not inflated, there is a certain distance between the sealing ring 5 and the sealing plate 1. When it is necessary to seal the sliding door 2 and the sealing plate 1, the exhaust throttle valve 9 is adjusted to input gas through the air pipe 11. The gas will fill the gap between the sealing seat 12 and the sealing ring 5, thereby causing the sealing ring 5 to bulge. After bulging, the sealing ring 5 abuts against the outer wall of the sealing plate 1, thereby achieving a sealing effect.

[0025] Specifically, one outer wall of the sliding door 2 is provided with a mounting groove, and the inner wall of the mounting groove is provided with a window 3.

[0026] It should be noted that during installation, the distance between the sealing ring 5 and the sealing plate 1 can be adjusted according to the specific situation. However, it is necessary to ensure that the sealing ring 5 does not come into contact with the sealing plate 1 when it is not inflated, but is in contact with the sealing plate 1 after inflation. The specific sealing condition of the sealing ring 5 depends on the actual situation. For example, the sealing ring 5 can be controlled to start contacting the sealing plate 1 when the inflation level reaches 80%. Further inflation will further increase the contact area between the sealing ring 5 and the sealing plate 1, thereby increasing its sealing effect. Therefore, it is not ideal for the sealing ring 5 to just touch the sealing plate 1 after full inflation.

[0027] Reference Figure 5In this embodiment, the gap between the sealing ring 5 and the sealing seat 12 is shaped like a "3" when it is not inflated, and shaped like a "C" when it is inflated.

[0028] Specifically, when the sealing ring 5 and the sealing seat 12 are not inflated, the middle part is concave inward because the material on both sides of the sealing ring 5 provides support, while the middle part can directly contact the sealing seat 12. Therefore, when inflated, the middle part bulges outward. During the bulging process, the sealing ring 5 slowly contacts the sealing plate 1, thereby achieving a sealing effect.

[0029] Reference Figure 3 and Figure 4 In this embodiment, a drag chain 8 is provided on one outer wall of the sealing plate 1, and the air tube 11 is disposed in the drag chain 8; the drag chain 8 can protect the air tube 11 and prevent the air tube 11 from being damaged by folding.

[0030] In this embodiment, the air pipe 11 has a two-section structure. One section of the air pipe 11 is located in the cable chain 8 and one end of the air pipe 11 is connected to the input end of the exhaust throttle valve 9. The other section of the air pipe 11 is connected to the output end of the exhaust throttle valve 9 and the other end of the other section of the air pipe 11 is connected to the gap of the sealing ring 5.

[0031] During inflation, gas is first introduced into the air pipe 11 inside the drag chain 8 through the outside. Then, the airflow is adjusted by the exhaust throttle valve 9 to allow the airflow to further enter the air pipe 11 in the air guide block 10, and then enter the gap between the sealing ring 5 and the sealing seat 12.

[0032] Reference Figure 4 and Figure 5 In this embodiment, the air guide block 10 has a hollow structure inside, and the air guide block 10 is used to guide the airflow from the exhaust throttle valve 9 through the air pipe 11 into the gap of the sealing ring 5.

[0033] In this embodiment, the driving assembly includes a mounting plate 4 disposed on the top of one outer wall of the sealing plate 1 and the top of the mounting plate 4. A linear slide rail 6 is disposed on the outer wall of the mounting plate 4 near the sealing plate 1. A driving cylinder 7 is disposed on the top of one outer wall of the sealing plate 1. The output end of the driving cylinder 7 is connected to the top of the sliding door 2. When the sliding door 2 needs to be moved, the driving cylinder 7 is activated to drive the sliding door 2 to move left and right on the linear slide rail 6. At the same time, the airflow or air pressure in the gap between the sealing ring 5 and the sealing seat 12 is adjusted by the exhaust throttle valve 9. When sealing is required, an inflation operation is performed, and when the sliding door 2 needs to be moved, an air release operation is performed. Slider blocks are disposed at the four corners of one outer wall of the sliding door 2. The sliding door 2 forms a sliding engagement with the linear slide rail 6 through the sliders.

[0034] Reference Figure 1 and Figure 2 In this embodiment, two through holes of the same size and shape are opened on one outer wall of the sealing plate 1. The coverage area of ​​the sliding door 2 is larger than the area of ​​the through holes, and the area enclosed by the sealing ring 5 is larger than the area of ​​the through holes. When performing the sealing operation according to the situation of the sliding door 2, the sealing ring 5 is placed between the sliding door 2 and the sealing plate 1, and the rectangular range enclosed by the sealing ring 5 must be larger than the through holes on the sealing plate 1 in order to ensure its sealing effect.

[0035] Working principle: When the sliding door 2 needs to be moved, the drive cylinder 7 is activated to move the sliding door 2 left and right on the linear slide rail 6. At the same time, the airflow or air pressure in the gap between the sealing ring 5 and the sealing seat 12 is adjusted by the exhaust throttle valve 9. When sealing is required, an inflation operation is performed, and when the sliding door 2 needs to be moved, an air release operation is performed. When sealing is required between the sliding door 2 and the sealing plate 1, the exhaust throttle valve 9 is adjusted to input gas through the air pipe 11. The gas will fill the gap between the sealing seat 12 and the sealing ring 5, thereby causing the sealing ring 5 to bulge. After bulging, the sealing ring 5 abuts against the outer wall of the sealing plate 1, thereby achieving a sealing effect.
