Technical Field

[0001] This utility model relates to the field of hyperbaric oxygen chamber technology, specifically a hyperbaric oxygen chamber door sealing structure based on pressure adaptive compensation. Background Technology

[0002] A hyperbaric oxygen chamber is a specialized medical device for hyperbaric oxygen therapy. Based on the different pressurizing media, it is divided into air-pressurized chambers and pure oxygen-pressurized chambers. Hyperbaric oxygen chambers have a wide range of applications, primarily used clinically for the treatment of anaerobic infections, carbon monoxide poisoning, air embolism, decompression sickness, hypoxic-ischemic encephalopathy, traumatic brain injury, and cerebrovascular diseases. A hyperbaric oxygen chamber typically consists of a chamber body, an air supply (oxygen) system, an air conditioning system, and a control system. The pressurizing medium is air or medical oxygen, and the pressure can automatically adapt and compensate according to usage.

[0003] To improve sealing, commercially available hyperbaric oxygen chambers typically use inward-opening doors. When the door is closed, it is sealed by the internal pressure of the chamber and the sealing strip. However, during pressurization inside the hyperbaric oxygen chamber, to achieve a seal as quickly as possible, the user usually needs to hold the door in place for a while until the internal pressure exceeds the external pressure. This causes inconvenience to the user, and the inward-opening door occupies a large space in the chamber, increasing space costs. Therefore, a pressure-adaptive compensation-based hyperbaric oxygen chamber door sealing structure is proposed to solve the problems mentioned above. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pressure adaptive compensation-based high-pressure oxygen chamber door sealing structure, which has the advantages of automatically sealing the door without manual intervention and saving chamber space costs. It solves the problems of inconvenience to users when sealing existing high-pressure oxygen chamber doors and the high space occupation and cost of inward-opening doors.

The chamber body has a first movable groove inside, and the door is slidably installed inside the first movable groove. The upper and lower sides of the door are provided with symmetrically distributed fixing mechanisms. A sealing strip is fixedly installed around the front of the door. Several electric telescopic rods with output ends extending into the first movable groove are fixedly installed on the rear side of the chamber body. These electric telescopic rods are evenly distributed around the door frame of the chamber body, and push plates are fixedly installed at the output ends of each electric telescopic rod. The lower fixing mechanism includes a movable plate, which is slidably installed on the bottom wall inside the first movable groove. A second movable groove is opened at the top of the movable plate, and the bottom end of the door is movably installed within the second movable groove. A spring is fixedly installed between the front side of the door and the front wall inside the second movable groove.

[0006] Furthermore, a rubber block is provided on the front side of the push plate.

[0007] Furthermore, each side of the fixing mechanism contains three springs, and the three spring arrays on each side are distributed on the front side of the hatch.

[0008] Furthermore, the inner upper and lower walls of the first movable groove are provided with sliding grooves, and the opposite sides of the upper and lower movable plates are provided with two sets of rollers extending into the sliding grooves.

[0009] Furthermore, door handles are fixedly installed on both the front and rear sides of the hatch, and the door handles on both sides extend to the front and rear sides of the hatch respectively.

[0010] Furthermore, a limit hook is rotatably installed on the left rear end of the cabin, and a protrusion located at the bottom of the limit hook is fixedly installed on the rear side of the cabin.

[0011] Furthermore, a contact sensor is fixedly installed on the inner left wall of the first movable groove, and the contact sensor is located at the middle of the inner left wall of the first movable groove.

[0012] Compared with the prior art, this utility model provides a high-pressure oxygen chamber door sealing structure based on pressure adaptive compensation, which has the following beneficial effects:

[0013] 1. The pressure adaptive compensation-based high-pressure oxygen chamber door sealing structure has the door slidably installed inside the chamber via the first movable groove. The use of a push-pull door can save space costs.

[0014] 2. This pressure-adaptive compensation-based hyperbaric oxygen chamber door sealing structure allows the door to close by pulling it to the left. The left side of the door then contacts a contact sensor, which transmits a control signal to the system. The system then controls the extension of multiple electric telescopic rods, and multiple push plates push the door forward until the sealing strip on the front of the door contacts the inside of the chamber, completing the seal. The entire process is simple and convenient for users, solving the problems of inconvenience caused by sealing existing hyperbaric oxygen chamber doors and the high space and cost associated with inward-opening doors.

[0021] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 5 The pressure-adaptive compensation-based hyperbaric oxygen chamber door sealing structure in this embodiment includes a chamber body 1 and a door 2. The chamber body 1 has a first movable groove 3 inside, and the door 2 is slidably installed inside the first movable groove 3. The push-pull door 2 saves space. The upper and lower sides of the door 2 are equipped with symmetrically distributed fixing mechanisms 4. Sealing strips 5 are fixedly installed around the front of the door 2. Several electric telescopic rods 6 with output ends extending into the first movable groove 3 are fixedly installed on the rear side of the chamber body 1. These electric telescopic rods 6 are evenly distributed around the door frame of the chamber body 1. Push plates 7 are fixedly installed at the output ends of the electric telescopic rods 6. Rubber blocks are provided on the front side of the push plates 7. When the push plates 7 move forward until they contact the rear side of the door 2, the rubber blocks on the front of the push plates 7 provide cushioning and prevent damage to the door 2. The lower fixing mechanism 4 includes a movable plate 401, which slides... The bottom of the hatch 2 is movably installed on the inner bottom wall of the first movable slot 3. The top of the movable plate 401 has a second movable slot 402. The bottom end of the hatch 2 is movably installed in the second movable slot 402. In order to prevent the sealing strip 5 from contacting the hatch 1 and causing friction when the hatch 2 is idle, a spring 403 is fixedly installed between the front side of the hatch 2 and the inner front wall of the second movable slot 402. There are three springs 403 in each side fixing mechanism 4, and the three springs 403 on each side are arranged in an array on the front side of the hatch 2. The multiple springs 403 can make the hatch 2 move backward and reset more stably. When in use, after the user enters the hatch 1, he pulls the hatch 2 to the left to close it. Then, by controlling the activation of multiple electric telescopic rods 6, the output ends extend, and multiple push plates 7 push the hatch 2 forward until the sealing strip 5 on the front side of the hatch 2 contacts the inner side of the hatch 1 to complete the seal. The whole operation process is simple and brings convenience to the user.

[0023] The inner upper and lower walls of the first movable groove 3 are provided with sliding grooves 8, and the opposite sides of the upper and lower movable plates 401 are provided with two sets of rollers 9 extending into the sliding grooves 8. The cooperation between the rollers 9 and the sliding grooves 8 can guide the movable plates 401 while reducing the friction of the movable plates 401, so that the hatch 2 can move better.

[0024] In this embodiment, door handles 10 are fixedly installed on both the front and rear sides of the hatch 2. The door handles 10 extend to the front and rear sides of the cabin 1 respectively, and the door handles 10 facilitate pushing the hatch 2 from the inside and outside. A limit hook 11 is rotatably installed on the left rear side of the cabin 1. A protrusion 12 is fixedly installed on the rear side of the cabin 1 at the bottom of the limit hook 11. When the user enters the cabin 1 and closes the hatch 2, the limit hook 11 can be rotated onto the door handle 10 inside to limit the hatch 2 and prevent the hatch 2 from rebounding due to inertia when it is closed, which would affect the subsequent sealing.

[0025] In this embodiment, a contact sensor 13 is fixedly installed on the inner left wall of the first movable groove 3. The contact sensor 13 is located in the middle of the inner left wall of the first movable groove 3. The contact sensor 13 can transmit signals to the system to control the activation of multiple electric telescopic rods 6, and can also determine whether the hatch 2 is completely closed.

[0026] The working principle of the above embodiments is as follows:

[0027] When in use, after the user enters the cabin 1, they pull the cabin door 2 to the left to close it. The left side of the cabin door 2 then contacts the contact sensor 13, which transmits a control signal to the system. The system then controls the extension of the output ends of multiple electric telescopic rods 6, and multiple push plates 7 push the cabin door 2 forward until the sealing strip 5 on the front side of the cabin door 2 contacts the inner side of the cabin 1 to complete the seal. After use, the output ends of the multiple electric telescopic rods 6 retract, and the cabin door 2, having lost its limit, moves backward and resets under the action of the spring 403, causing the sealing strip 5 to separate from the inner wall of the cabin 1. At this point, the cabin door 2 can be moved and pushed open. The entire operation is simple and convenient for the user.

[0028] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
