Description

Technical Field

[0001] This invention relates to the field of sealing door structure technology, and in particular to a movable sealing door assembly and its door panel and sealing mechanism. Background Technology

[0002] my country possesses the world's largest plateau region, covering approximately one-quarter of its land area. This plateau region is crucial for the economic and social development of my country's diverse ethnic groups in its western border regions, and also boasts the widest distribution of my country's national defense border. Due to the harsh geographical and climatic environment of high altitudes—characterized by year-round low temperatures, thin air, low atmospheric pressure, and low oxygen levels—people from plains areas who travel to these regions for economic and social development often experience severe altitude sickness, including rapid heart rate, dizziness, decreased physical strength, and dehydration. This causes significant damage to physiological functions and severely reduces work efficiency and quality of life.

[0003] To mitigate these adverse effects, the building or cabin can be pressurized to adjust the internal air pressure to be comparable to that of plains areas, thus addressing altitude sickness. Most existing pressurized buildings or cabins use inward-opening swing doors for personnel access, typically sealed by a sealant between the door panel and frame. Sealing requires manual application of initial pressure to ensure a tight seal between the sealant and the door frame, followed by further sealing through increasing pressurization pressure. However, repeated pressurization and depressurization can degrade the sealant, leading to air leakage and malfunction. Furthermore, the inward-opening swing door's direction hinders evacuation in emergencies and occupies valuable interior space during opening and closing. Sliding doors, due to their high throughput, aesthetic appeal, and ease of automatic control, are widely used in demanding applications. However, because the door panel and frame can slide without pre-compression, gaps are difficult to fill, resulting in poor sealing. Summary of the Invention

[0004] The main objective of this invention is to provide a movable sealing door assembly, its door panel, and sealing mechanism, which aims to facilitate the movable connection between the door body and the door frame while ensuring the sealing performance of the movable door.

[0005] To achieve the above objectives, the present invention provides a sealing mechanism for a movable sealing door assembly, comprising a movable sealing frame, a pressing mechanism, a sealing element, and a transmission mechanism, wherein...

[0006] The sealing element is fixed on the side of the movable sealing frame near the door panel, and the transmission mechanism is connected to the movable sealing frame to adjust the distance between it and the door panel.

[0007] The transmission mechanism includes an elastic rod located on the side of the movable sealing frame to contact the closed door panel, and a rotating rod located on the outside of the movable sealing frame. A pressing mechanism and a rotating cylinder are fixed on the rotating rod. An arc-shaped groove is provided on the rotating cylinder. The elastic rod extends into a sliding rod. The end of the sliding rod is inserted into the arc-shaped groove and slides to drive the rotating rod to rotate. After the pressing mechanism follows the rotation of the rotating rod, it contacts the movable sealing frame to drive it to move closer to the door panel or away from it, thereby driving the sealing element to press or move away from the door panel.

[0008] Preferably, the clamping mechanism is a cam fixed to the outside of the rotating rod, and the inner and outer end faces of the door panel are respectively provided with movable sealing frames.

[0009] Preferably, the elastic rod includes a push rod and a fixed cylinder sleeved on and elastically connected to the end of the push rod, the fixed cylinder being fixed to the door frame, and the push rod being fixedly connected to the sliding rod.

[0010] Preferably, each of the movable sealing frames located at both ends of the door panel is provided with an elastic rod and a rotating rod, and the elastic rod further includes a connecting plate that connects the push rods of the two movable sealing frames.

[0011] Preferably, the sealing mechanism of the movable sealing door assembly further includes a connecting strip located between the door frame and the movable sealing frame to seal the gap between them.

[0012] Preferably, the movable sealing frame is fixed with a positioning rod on the side near the door frame, and a positioning cylinder is fixed on the door frame. The positioning cylinder is sleeved outside the positioning rod, and the positioning rod is movable relative to the positioning cylinder.

[0013] The present invention further proposes a door panel for use with the sealing mechanism of the above-mentioned movable sealing door assembly. The end face of the door panel near the movable sealing frame is provided with a sealing groove adapted to its sealing element, and the side of the door panel is provided with a circular groove for the drive rod of the drive mechanism to be inserted.

[0014] Preferably, a sliding sleeve for the guide rod to pass through is fixed on the top of the door panel.

[0015] Preferably, a guide groove adapted to the guide plate on the door frame is provided on the bottom surface of the door panel.

[0016] The present invention further proposes a movable sealing door assembly, including the door panel described above, a door frame adapted to the door panel, and a drive mechanism connecting the door frame and the door panel. The base of the drive mechanism is fixed on the door frame, and the output rod of the drive mechanism extends into the circular groove of the door panel and connects thereto.

[0017] Preferably, the movable sealing door assembly further includes a guide rod fixed to the door frame, the guide rod passing through the sliding sleeve of the door panel.

[0018] Preferably, the movable sealing door assembly further includes a guide plate fixed to the bottom surface of the door frame, the guide plate being inserted into the guide groove of the door panel.

[0019] Preferably, a rubber ring is installed on the edge of the door frame.

[0020] The sealing mechanism of the movable sealing door assembly proposed in this invention uses a movable sealing frame and sealing elements in conjunction with a movable door panel. When the door panel is closed, the movable sealing frame moves closer to the door panel to seal it tightly. When the door panel is opened, the movable sealing frame moves outward without interfering with the opening of the door panel, thus achieving a seal on the movable door panel. In addition, the movable sealing frames on both sides exert lateral clamping pressure on the door body, which can improve the stability of the door panel. This is suitable for pressurized buildings where the internal and external air pressures differ, ensuring structural stability and sealing performance at all times. Attached Figure Description

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] This invention proposes a sealing mechanism for a movable sealing door assembly.

[0036] Reference Figures 1 to 10 In this preferred embodiment, a sealing mechanism for a movable sealing door assembly includes a movable sealing frame 7, a pressing mechanism, a sealing element 8 (which may be a sealing ring), and a transmission mechanism.

[0037] The sealing element 8 is fixed on the side of the movable sealing frame 7 near the door panel 2, and the transmission mechanism is connected to the movable sealing frame 7 to adjust the distance between it and the door panel 2.

[0038] The transmission mechanism includes an elastic rod located on the side of the movable sealing frame 7 to contact the closed door panel 2, and a rotating rod 13 located on the outside of the movable sealing frame 7 (the rotating rod 13 is supported on the door frame 1 by a bearing, thereby realizing rotation relative to the door frame 1). A pressing mechanism and a rotating cylinder 15 are fixed on the rotating rod 13. An arc-shaped sliding groove 1501 is provided on the rotating cylinder 15. The elastic rod extends into a sliding rod 1701. The end of the sliding rod 1701 is inserted into the arc-shaped sliding groove 1501 and slides to drive the rotating rod 13 to rotate. After the pressing mechanism rotates, it contacts the movable sealing frame 7 to drive it to move closer to or away from the door panel 2, thereby driving the sealing element 8 to press or move away from the door panel 2.

[0039] Specifically, in this embodiment, the clamping mechanism uses a cam 14. Furthermore, in this embodiment, at least two cams 14 are provided on each rotating rod 13, thereby stably pushing the movable sealing frame 7 to perform fine-tuning of the distance.

[0040] Furthermore, referring to Figure 4 The inner and outer ends of the door panel 2 are each provided with a movable sealing frame 7, which seals the inner and outer sides of the door body, thereby improving the sealing performance of this sealing mechanism.

[0041] In this embodiment, refer to Figure 5 The elastic rod includes a push rod 17 and a fixed cylinder 16 sleeved on and elastically connected to the end of the push rod 17. The fixed cylinder 16 is fixed to the door frame 1, and the push rod 17 is fixedly connected to the sliding rod 1701. Specifically, the end of the push rod 17 is elastically connected to the fixed cylinder 16 by a spring.

[0042] The push rod 17 is elastically connected to the fixed cylinder 16, which ensures that when the sliding door panel 2 is opened, the spring's rebound force can drive the cam 14 to rotate, releasing the movable sealing frame 7 and the sealing element 8, thus allowing the door panel 2 to slide freely.

[0043] In this embodiment, refer to Figure 4 The movable sealing frames 7 located at both ends of the door panel 2 are respectively equipped with elastic rods and rotating rods 13. Furthermore, an elastic rod and a rotating rod 13 are provided at the top and bottom of the movable sealing frame 7. In this way, when the door panel 2 is closed, the cam 14 rotates and the movable sealing frame 7 can press the door panel 2 tightly in all directions, thereby pressing the sealing element 8, thus improving the overall sealing effect.

[0044] Furthermore, referring to Figure 6 The elastic rod also includes a connecting plate 18 that connects the push rods 17 of the two movable sealing frames 7. Therefore, the door panel 2 directly contacts the connecting plate 18, thereby simultaneously pushing the two push rods 17 to move.

[0045] Furthermore, referring to Figure 7 and Figure 8 The sealing mechanism of this movable sealing door assembly also includes a connecting strip 6 located between the door frame 1 and the movable sealing frame 7 to seal the gap between them. The connecting strip 6 can be made of a flexible material. One end of the connecting strip 6 is connected to the rubber ring 10 on the door frame 1, and the other end is fixedly connected to the movable sealing frame 7 to ensure sealing performance. Because the connecting strip 6 is flexible, it can deform, ensuring a stable connection between the movable sealing frame 7 and the connecting strip 6 during movement.

[0046] In this embodiment, the sealing grooves 202 on both sides of the door panel 2 and the connecting strip 6 facilitate the sealing between the sealing strip and the door frame 1. The sealing strip entering the sealing groove 202 can improve the sealing performance between the door frame 1 and the door panel 2.

[0047] In this embodiment, refer to Figure 4 A positioning rod 11 is fixed on the side of the movable sealing frame 7 near the door frame 1, and a positioning cylinder 12 is fixed on the door frame 1. The positioning cylinder 12 is sleeved on the outside of the positioning rod 11, and the positioning rod 11 is movable relative to the positioning cylinder 12.

[0048] The positioning rod 11 and the positioning cylinder 12 form a positioning mechanism, and each set of movable sealing frame 7 is equipped with at least three positioning mechanisms. By setting the positioning mechanism, the movable sealing frame 7 is connected to the door frame 1, and the distance between the two can be adjusted by sliding the positioning rod 11.

[0049] The working process of this sealing mechanism is as follows.

[0050] When the drive mechanism 3 closes the door panel 2, the right side of the door panel 2 pushes the connecting plate 18 to move to the right, thereby causing the two push rods 17 connected to it to move to the right. Since the push rods 17 are inserted into the fixed cylinder 16, the springs set in the fixed cylinder 16 are compressed. At the same time, the sliding rod 1701 at the bottom of the push rod 17 moves to the right. Since the sliding rod 1701 is inserted into the arc-shaped groove 1501 on the rotating cylinder 15, the rotating cylinder 15 is pushed to rotate. When the rotating cylinder 15 rotates, it drives the rotating rod 13 to rotate, causing the cam 14 on the rotating rod 13 to rotate. The rotation of the cam 14 can push the movable sealing frame 7 to move closer to the door panel 2. When it moves into place, the movable sealing frame 7 presses the sealing element 8 tightly into the sealing groove 202 on the door panel 2, so that the door panel 2 and the door frame 1 are sealed.

[0051] The sealing mechanism of the movable sealing door assembly proposed in this embodiment uses a movable sealing frame 7 and a sealing element 8 in conjunction with the movable door panel 2. When the door panel 2 is closed, the movable sealing frame 7 moves closer to the door panel 2 to seal it tightly. When the door panel 2 is opened, the movable sealing frame 7 moves outward without interfering with the opening of the door panel 2, thus achieving a seal on the movable door panel 2. In addition, the movable sealing frames 7 on both sides exert a clamping pressure on the door body, which can improve the stability of the door panel 2. It is suitable for maintaining structural stability and sealing performance when there are different air pressures inside and outside pressurized buildings.

[0052] The present invention further proposes a door panel for a movable sealing door assembly.

[0053] Reference Figure 10In this preferred embodiment, a door panel 2 is used in conjunction with the sealing mechanism of the movable sealing door assembly as described above. The end face of the door panel 2 near the movable sealing frame 7 has a sealing groove 202 adapted to its sealing element 8. A circular groove 201 is provided on the side of the door panel 2 for the insertion of the drive rod of the drive mechanism 3. Two circular grooves 201 are provided.

[0054] Furthermore, a sliding sleeve 5 for the guide rod 4 to pass through is fixed to the top of the door panel 2. At least two sliding sleeves 5 are provided.

[0055] Furthermore, a guide groove 203 adapted to the guide plate 9 on the upper part of the door frame 1 is provided on the bottom surface of the door panel 2.

[0056] In this embodiment, the sliding sleeve 5 and the guide groove 203 cooperate with the guide rod 4 and guide plate 9 of the door frame to limit and guide the top and bottom of the door panel 2 respectively, so as to facilitate the sliding of the door panel 2 and improve the stability of the door panel 2 during the sliding process.

[0057] The door panel 2 proposed in this embodiment realizes the sliding structure of the door panel 2, and at the same time, it is tightly and reliably sealed with the door frame 1.

[0058] The present invention further proposes a movable sealing door assembly.

[0059] In this preferred embodiment, refer to Figures 1 to 4 A movable sealing door assembly includes the aforementioned door panel 2, a door frame 1 adapted to the door panel 2, and a drive mechanism 3 connecting the door frame 1 and the door panel 2. The base of the drive mechanism 3 is fixed to the door frame 1, and the output rod of the drive mechanism 3 extends into the circular groove 201 of the door panel 2 and connects thereto.

[0060] Specifically, in this embodiment, the drive mechanism 3 uses a small servo electric cylinder. Two small servo electric cylinders may be provided.

[0061] Furthermore, referring to Figure 7 and Figure 8 A rubber ring 10 is installed on the edge of the door frame 1. The edge of the door frame 1 refers to the quadrilateral edge that is opened inside it, and the rubber ring 10 has a square structure.

[0062] Furthermore, referring to Figure 2 and Figure 3 The movable sealing door assembly also includes a guide rod 4 fixed to the door frame 1, which passes through the sliding sleeve 5 of the door panel 2.

[0063] Furthermore, referring to Figure 7 and Figure 8 The movable sealing door assembly also includes a guide plate 9 fixed to the bottom surface of the door frame 1, and the guide plate 9 is inserted into the guide groove 203 of the door panel 2.

[0064] In this embodiment, by setting guide rod 4 and guide plate 9, the top and bottom of door panel 2 are respectively limited and guided, which facilitates the sliding of door panel 2 and improves the stability of door panel 2 during the sliding process.

[0065] The movable sealing door assembly proposed in this embodiment can realize the sliding closing and opening of the door panel 2. After closing, it pushes the sealing strip tightly against both sides of the door panel 2, thereby keeping the wall panel and the door panel 2 sealed. At the same time, the pressure on both sides clamps the sides of the door panel 2, thereby improving the stability of the door panel 2. It is suitable for maintaining a stable seal when the air pressure inside and outside the pressurized building is different.

[0066] The above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural transformations made based on the description and drawings of the present invention, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
