Description

Technical Field

[0001] This utility model relates to the technical field of cabin door clamping devices, and more specifically, to a high-pressure oxygen chamber cabin door clamping device. Background Technology

[0002] Hyperbaric oxygen chambers are specialized medical devices for hyperbaric oxygen therapy. They are divided into two types according to the pressurization medium: air hyperbaric chambers and pure oxygen hyperbaric chambers. Hyperbaric oxygen chambers have a wide range of applications and are mainly used clinically for the treatment of anaerobic bacterial infections, CO poisoning, air embolism, decompression sickness, hypoxic-ischemic encephalopathy, traumatic brain injury, and cerebrovascular diseases. With the development of science and medical technology, hyperbaric oxygen chambers have become increasingly popular.

[0003] However, the existing hyperbaric oxygen chamber door closing structure has obvious defects: First, most of them adopt a single closing method of "hinge and handle", and the seal relies on the pressure between the door and the chamber body. Under high pressure, uneven pressure distribution can easily cause local gaps, leading to media leakage. Second, there is a lack of an adjustable pressure compensation mechanism, which cannot dynamically adjust the sealing force according to changes in the chamber pressure or the wear of the seals. After long-term use, the risk of leakage will continue to increase. Therefore, a hyperbaric oxygen chamber door clamping device is provided. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a hyperbaric oxygen chamber door clamping device, which aims to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a hyperbaric oxygen chamber door clamping device, including a door installed on a hyperbaric oxygen chamber, and a pressurizing component is provided on the door; The pressurization assembly includes a cover plate disposed on the top of the hatch, a connecting ring disposed on the top of the cover plate, and an installation hole disposed in the middle of the connecting ring; A sealing cover is rotatably connected to the middle of the mounting hole. An extension tube is provided at the bottom end of the sealing cover. A sealing plate is provided at the bottom of the extension tube. Several elastic pressure blocks are distributed on the sealing plate.

[0006] Optionally, in a possible implementation, the vertical cross-sectional shape of the plurality of elastic pressure blocks is set to a triangle, and each elastic pressure block is distributed on the sealing plate along the axial circumference of the sealing plate, the sealing plate being located at the top of the inner cavity of the hatch and abutting against the top of the inner wall of the hatch. Optionally, in a possible implementation, a mounting platform is fixedly provided on the top of the hatch, the cover plate is located inside the mounting platform, a plurality of observation ports are provided on the outside of the hatch, and each of the observation ports is provided with tempered glass. Two hinge seats are fixedly provided on the hatch, and each of the hinge seats is rotatably connected to a rotating shaft. An extension lug is fixedly provided on the rotating shaft, and the extension lug extends to the cover plate and is fixedly connected to the cover plate. The technical effects and advantages of this utility model are as follows: The threaded engagement between the sealing cover and the connecting ring allows for precise control of axial pressure, causing the sealing plate to fit tightly against the chamber's sealing surface. The triangular elastic pressure block converts axial force into uniform radial pressure, covering the entire circumference of the sealing plate. This prevents gaps caused by weak local pressure, effectively preventing air or pure oxygen leakage and ensuring stable pressure inside the chamber. Furthermore, the tightening and unlocking actions can be completed simply by rotating the sealing cover, making it easy for medical staff to learn. At the same time, the threaded adjustment method supports dynamic compensation of the sealing force. When the seal wears slightly, the pressure can be supplemented by fine-tuning the sealing cover, eliminating the need for frequent component replacement, extending the service life of the device, and reducing maintenance costs.

Detailed Implementation

[0013] 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.

[0014] This embodiment relates to the technical field of door clamping devices, specifically a door clamping device for hyperbaric oxygen chambers. It is applicable to various hyperbaric oxygen therapy equipment such as air pressurization chambers and pure oxygen pressurization chambers, and can solve the problem of medium leakage caused by the non-tight closure of existing hyperbaric oxygen chamber doors.

[0015] The hyperbaric oxygen chamber door clamping device disclosed in this embodiment has the following overall structure: Figure 1 As shown, the core components include hatch 1 and a pressurization assembly mounted on hatch 1. The connection relationships and details of each component are as follows: The main structure of hatch 1 is circular to ensure structural strength under high-pressure environments. For example... Figure 2 As shown, several observation ports 10 are evenly arranged along the circumference on the outer side of the cabin door 1. Each observation port 10 is fixedly fitted with tempered glass 11. The connection between the tempered glass 11 and the observation port 10 is sealed with a silicone rubber sealing ring, which facilitates medical staff to observe the patient's condition inside the cabin and prevents the medium from leaking from the observation port 10.

[0016] At the same time, such as Figure 2 , Figure 4 As shown, two hinge seats 12 are symmetrically fixed on the top of the outer side of the hatch 1. The hinge seats 12 are made of stainless steel and are fixed to the hatch 1 by welding. A rotating shaft 13 is rotatably connected inside each hinge seat 12. The axial direction of the rotating shaft 13 is consistent with the radial direction of the hatch 1. An extension ear 14 is integrally formed at the end of the rotating shaft 13 away from the hinge seat 12. The extension ear 14 is "L" shaped, and its free end is fixedly connected to the cover plate 2 by bolts, so as to realize the rotatable connection between the cover plate 2 and the hatch 1.

[0017] In addition, such as Figure 2 As shown, an annular mounting platform 9 is integrally formed on the inner side of the top of the hatch 1. The inner diameter of the mounting platform 9 is adapted to the outer diameter of the cover plate 2. The cover plate 2 can be embedded in the mounting platform 9. The mounting platform 9 is used to radially limit the cover plate 2 and prevent the cover plate 2 from shifting.

[0018] The pressurization assembly is the core component for achieving the clamping of hatch 1, such as... Figure 1 , Figure 3As shown, it includes a cover plate 2, a connecting ring 3, a sealing cover 5, an extension tube 6, a sealing plate 7, and an elastic pressure block 8, with the specific structure as follows: The cover plate 2 is circular, and its diameter is the same as the inner diameter of the mounting platform 9. The center of the cover plate 2 is welded and fixed to the connecting ring 3. The connecting ring 3 is an annular stainless steel part. The connecting ring 3 has an axial mounting hole 4 in the middle, and the inner wall of the mounting hole 4 is provided with internal threads.

[0019] The sealing cover 5 and the connecting ring 3 are threadedly matched in the mounting hole 4 to achieve a threaded rotational connection between the sealing cover 5 and the connecting ring 3; the bottom end of the lower connecting section of the sealing cover 5 is fixed to the extension tube 6 by welding.

[0020] The extension tube 6 is a hollow cylinder made of stainless steel, and its bottom end is fixedly connected to the sealing plate 7 by bolts. The sealing plate 7 is circular, with a diameter that matches the inner diameter of the hatch 1. It is made of high-pressure resistant plastic material, and the sealing plate 7 is located at the top of the inner cavity of the hatch 1, with its edge in close contact with the top of the inner wall of the hatch 1.

[0021] like Figure 3 As shown, several elastic pressure blocks 8 are evenly distributed along the circumference of the sealing plate 7. The vertical cross-section of each elastic pressure block 8 is triangular and the material is nitrile rubber. The elastic pressure blocks 8 are fixed to the side of the sealing plate 7 away from the extension cylinder 6 by a vulcanization process, and the tips of each elastic pressure block 8 face the same direction and are arranged clockwise or counterclockwise along the circumference of the sealing plate 7.

[0022] The specific working principle is as follows: First, the hatch 1 is connected to the hyperbaric oxygen chamber body by bolts or hinges. The conventional connection structure is not shown in the attached drawings. Then, the pressurization components are assembled in sequence: the cover plate 2 is embedded into the mounting platform 9 of the hatch 1 and fixed to the pivot 13 of the hinge seat 12 by the extension lug 14. Then, the sealing cover 5 is threadedly connected to the mounting hole 4 of the connecting ring 3 to complete the installation of the entire device.

[0023] When closing hatch 1, first rotate hatch 1 around the hatch hinge until it fits snugly against the hatch body. Then, rotate the sealing cover 5 using a tool or manually. The sealing cover 5 moves upward along the mounting hole 4 through the threaded engagement with the connecting ring 3, driving the extension tube 6 upward synchronously; The extension tube 6 pushes the sealing plate 7 towards the top of the cabin, increasing the contact force between the edge of the sealing plate 7 and the top of the inner wall of the cabin door 1, while each triangular elastic pressure block 8 contacts the sealing surface of the cabin. As the sealing cover 5 continues to rotate, the elastic pressure block 8 is squeezed and undergoes elastic deformation. Its triangular structure can convert axial pressure into radial pressure along the sealing surface, so as to achieve full and uniform contact between the sealing plate 7 and the sealing surface of the cabin, and finally complete the pressing of the hatch 1 to avoid media leakage.

[0024] After the treatment is completed, rotate the sealing cover 5 in the opposite direction. The sealing cover 5 moves downward along the mounting hole 4. The extension cylinder 6 drives the sealing plate 7 away from the sealing surface of the cabin. The elastic pressure block 8 returns to its deformation and the clamping force is released. Then the cabin door 1 can be opened around the cabin hinge.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
