Description

Technical Field

[0001] This invention relates to the field of hyperbaric oxygen chamber technology, specifically a vehicle-mounted mobile hyperbaric oxygen chamber. Background Technology

[0002] A hyperbaric oxygen chamber is a medical device used to treat diseases by inhaling high concentrations of oxygen at an environment above one atmosphere of pressure. It is widely used in hospitals and emergency facilities. In the event of sudden disasters, major accidents, or in remote areas, there is a need for mobile hyperbaric oxygen chambers that can quickly reach the scene and immediately provide hyperbaric oxygen therapy. Existing mobile hyperbaric oxygen chambers typically have the finished chamber body directly fixed inside the cargo box of a vehicle or rigidly welded to the chassis with bolts.

[0003] However, most existing vehicle-mounted hyperbaric oxygen chambers are rigidly fixed to the vehicle body and cannot be quickly disassembled. When internal components need major repairs or replacements, the entire vehicle must be sent for repair, which is inconvenient and costly. Secondly, traditional vehicle-mounted oxygen chambers can usually only be accessed from the outside of the vehicle, making it inconvenient for accompanying medical staff to directly enter from the driver's seat to care for patients, and it is also inconvenient to enter and exit when the external environment is harsh. At the same time, most traditional oxygen chamber doors use independent sealing rings, which lose elasticity under different high-pressure environments, thus affecting the sealing performance. Furthermore, the sealing rings also lose elasticity after prolonged use, further reducing the sealing performance. Summary of the Invention

[0004] To address the problems in the prior art, the present invention provides a vehicle-mounted mobile hyperbaric oxygen chamber.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a vehicle-mounted mobile hyperbaric oxygen chamber, including a vehicle body and a hyperbaric oxygen chamber installed on the vehicle body, wherein the vehicle body is equipped with an installation mechanism for detachable installation of the hyperbaric oxygen chamber, and the installation mechanism is equipped with a communication mechanism for facilitating entry and exit of the hyperbaric oxygen chamber.

[0006] Specifically, the installation mechanism includes a fixed box, which is detachably connected to the vehicle body via fasteners. The fixed box has an installation groove inside, the top of which extends to the outside of the top of the fixed box, and the hyperbaric oxygen chamber is slidably connected to the inside of the installation groove.

[0007] Specifically, the fixed box is located between the front of the vehicle and the carriage on the vehicle body. The top of the hyperbaric oxygen chamber is flush with the top of the fixed box. Guide grooves are provided at the center lines of both ends of the hyperbaric oxygen chamber. Reinforcing ribs are welded at the center lines of both ends of the mounting groove. The guide grooves are slidably connected to the outer side of the reinforcing ribs.

[0008] Specifically, the communication mechanism includes a first inlet and outlet, and the fixed box is provided with a first inlet and outlet at the center of one side and one end, respectively. The first inlet and outlet on the side of the fixed box is connected to the driver's cab, and the hyperbaric oxygen chamber is provided with a second inlet and outlet at the center of one side and one end, respectively, corresponding to the first inlet and outlet.

[0009] Specifically, the area of ​​the first inlet / outlet on one side of the fixed box is larger than the area of ​​the first inlet / outlet at one end of the fixed box. The two first inlets / outlets are respectively connected to hatches by hinges. The hatches are located on the outside of the fixed box. The hatches on one side of the fixed box extend into the driver's cab. The two hatches are each equipped with a handle on both sides.

[0010] Specifically, sealing gaskets are installed at the edges of the two second inlet and outlet ports respectively. The outer side of the sealing gasket is slidably connected to the inner wall of the mounting groove. The edge of the hatch and the inner wall of the first inlet and outlet port are both stepped structures.

[0011] Specifically, each of the two hatches is equipped with a locking mechanism for controlling the opening and closing of the fixed box. The locking mechanism includes a lock groove, with a lock groove located at the center of one side of each of the two first inlet / outlet ports. A locking pin is installed at the center line of one end of each of the two hatches. The locking pin is slidably connected to the inside of the hatch via a return spring. One end of the locking pin extends to the outside of the hatch and engages with the inside of the lock groove. The other end of the locking pin has a hemispherical structure. A drive disc is rotatably connected to the inside of each of the two hatches via a rotating shaft. Both ends of the two rotating shafts extend to the outside of the hatch and are connected to two handles. The handles are rotatably connected to the outside of the hatch via the rotating shaft. The drive disc has symmetrically distributed drive grooves on its outer side. The other end of the locking pin abuts against the outer side of the drive disc.

[0012] Specifically, the drive disk has symmetrical positioning grooves on its outer side, and the angle between the two positioning grooves and the two drive grooves is 90 degrees. The inner diameter of the positioning grooves is much smaller than the inner diameter of the drive grooves.

[0013] Specifically, each of the two hatches is equipped with a sealing mechanism for maintaining a seal with the fixed box. The sealing mechanism includes a sealing ring. The sealing ring is engaged with the outer steps of each of the two hatches. The sealing ring has a frame structure and abuts against the inner steps of the first inlet / outlet wall. Control components for controlling the expansion of the sealing ring are installed inside each of the two hatches.

[0014] Specifically, the control assembly includes a connecting pipe, an airbag, a pressure block, a drive rod, and a compression spring. Airbags are installed inside each of the two hatches, and a connecting pipe connects the airbag to the sealing ring. Drive rods are installed inside each of the two hatches, and the drive rods are slidably connected to the inside of the hatches via compression springs. One end of the drive rod has a hemispherical structure and abuts against a positioning groove on the outside of the drive disc. A pressure block is installed at the other end of the drive rod, and the pressure block abuts against one end of the airbag.

[0015] Specifically, the top of the hyperbaric oxygen chamber is equipped with a suspension mechanism at both ends for easy connection to an external crane. The suspension mechanism includes a connecting block. The connecting block is installed inside both ends of the hyperbaric oxygen chamber. The top of the hyperbaric oxygen chamber is provided with two through slots. The tops of the two connecting blocks extend into the through slots. The tops of the two connecting blocks are rotatably connected to pull rings.

[0016] Specifically, each of the two channels is slidably connected to a sliding plate at its top. The sliding plate has an "L" shape, and one end of the bottom of the sliding plate is slidably connected to the inside of the hyperbaric oxygen chamber. The length of the bottom of the sliding plate is greater than the length of the channel. A telescopic spring is connected between the bottom of the connecting block and the hyperbaric oxygen chamber. The connecting block is slidably connected to the inner top of the hyperbaric oxygen chamber through the telescopic spring.

[0017] Specifically, the inner sides of both ends of the top of the hyperbaric oxygen chamber are respectively equipped with limiting mechanisms for limiting the position between the hyperbaric oxygen chamber and the fixed box. The limiting mechanism includes limiting rods. Symmetrical limiting rods are respectively installed on the inner sides of both ends of the top of the hyperbaric oxygen chamber. The limiting rods are slidably connected to the inside of the hyperbaric oxygen chamber through abutment springs. The bottom outer side of the connecting block is provided with a groove. The two reinforcing ribs are respectively provided with limiting grooves corresponding to the limiting rods on opposite sides. One end of the limiting rod extends to the outside of the hyperbaric oxygen chamber and engages with the limiting groove. The other end of the limiting rod is a hemispherical structure and abuts against the outside of the connecting block. The groove is located at the bottom of the limiting rod.

[0018] The beneficial effects of this invention are: (1) The vehicle-mounted mobile hyperbaric oxygen chamber described in this invention facilitates the stable installation of the hyperbaric oxygen chamber on the vehicle body through the installation mechanism, and at the same time, with the suspension mechanism, it is convenient for the crane to lift the hyperbaric oxygen chamber, realize the disassembly and assembly of the hyperbaric oxygen chamber and the fixed box, and facilitate subsequent maintenance.

[0019] (2) The vehicle-mounted mobile hyperbaric oxygen chamber described in this invention uses a limiting mechanism to limit the hyperbaric oxygen chamber and the fixed box, making the hyperbaric oxygen chamber securely installed.

[0026] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0027] like Figure 1 , Figure 2 , Figure 5 and Figure 11 As shown, a vehicle-mounted mobile hyperbaric oxygen chamber of the present invention includes a vehicle body 1 and a hyperbaric oxygen chamber 2 installed on the vehicle body 1. The vehicle body 1 is equipped with an installation mechanism 3 for detachable installation of the hyperbaric oxygen chamber 2. The installation mechanism 3 is equipped with a communication mechanism 4 for facilitating entry and exit of the hyperbaric oxygen chamber 2. The hyperbaric oxygen chamber 2 integrates a pressure regulation system, an oxygen supply system, an environmental monitoring and control system, and safety protection devices. The pressure regulation system consists of an air compressor, an air tank, and a pressure reducing valve, enabling pressurization, stabilization, and depressurization control within the chamber. The oxygen supply system includes an oxygen generator, an oxygen booster pump, oxygen supply pipelines, and an in-chamber oxygen supply terminal, providing patients with high-concentration oxygen. The environmental monitoring system uses pressure and oxygen concentration sensors to monitor chamber parameters in real time, and a PLC controller, in conjunction with a touchscreen, enables automatic adjustment and display.

[0028] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 11As shown, the installation mechanism 3 includes a fixed box 301, which is detachably connected to the vehicle body 1 by fasteners. The fixed box 301 has an installation groove 302 inside, and the top of the installation groove 302 extends to the outer side of the top of the fixed box 301. The hyperbaric oxygen chamber 2 is slidably connected to the inside of the installation groove 302. The detachable installation of the fixed box 301 and the vehicle body 1 facilitates subsequent disassembly and maintenance. The installation groove 302 facilitates the sliding connection between the hyperbaric oxygen chamber 2 and the inside of the fixed box 301, which is convenient for subsequent disassembly and maintenance.

[0029] Specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, the fixed box 301 is located between the front and the cargo compartment of the vehicle body 1. The top of the hyperbaric oxygen chamber 2 is flush with the top of the fixed box 301. Guide grooves 304 are provided at the center lines of both ends of the hyperbaric oxygen chamber 2. Reinforcing ribs 303 are welded at the center lines of both ends of the mounting groove 302. The guide grooves 304 and the outer side of the reinforcing ribs 303 are slidably connected. The hyperbaric oxygen chamber 2 is installed between the front and the cargo compartment of the vehicle body 1 to protect the hyperbaric oxygen chamber 2. At the same time, it is convenient for drivers to enter the interior of the hyperbaric oxygen chamber 2 through the cab. The installation of the reinforcing ribs 303 helps to reinforce both ends of the fixed box 301. The opening of the guide grooves 304, with the cooperation of the reinforcing ribs 303, plays a guiding role when the hyperbaric oxygen chamber 2 is disassembled and assembled.

[0030] Specifically, such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the connecting mechanism 4 includes a first inlet / outlet 403. The first inlet / outlet 403 is provided at the center of one side and one end of the fixed box 301, and the first inlet / outlet 403 on the side of the fixed box 301 is connected to the driver's cab. The second inlet / outlet 404 corresponding to the first inlet / outlet 403 is provided at the center of one side and one end of the hyperbaric oxygen chamber 2. The opening of the two second inlet / outlet 404 facilitates the provision of an inlet / outlet for the hyperbaric oxygen chamber 2, making it convenient for personnel to enter and exit. The opening of the two first inlet / outlet 403 facilitates the connection between the first inlet / outlet 403 and the second inlet / outlet 404 after the hyperbaric oxygen chamber 2 is installed with the fixed box 301, allowing personnel to enter and exit the hyperbaric oxygen chamber 2 through the driver's cab or outside the vehicle, making entry and exit more convenient.

[0031] Specifically, such as Figure 1As shown, the area of ​​the first inlet / outlet 403 on one side of the fixed box 301 is larger than the area of ​​the first inlet / outlet 403 at one end of the fixed box 301. The two first inlets / outlets 403 are respectively connected to hatches 401 by hinges. The hatches 401 are located on the outside of the fixed box 301. The hatches 401 on one side of the fixed box 301 extend to the inside of the driver's cab. Handles 402 are installed on both sides of the two hatches 401. The opening of the two first inlets / outlets 403 with different areas facilitates personnel to enter through the driver's cab and outside the vehicle. The installation of the hatches 401 facilitates the opening and closing of the two first inlets / outlets 403, facilitating personnel entry and safety protection. At the same time, the installation of the handles 402 facilitates the control of the opening and closing of the hatches 401.

[0032] Specifically, such as Figure 2 , Figure 4 and Figure 5 As shown, sealing gaskets 405 are installed at the edges of the two second inlets and outlets 404 respectively. The outer side of the sealing gasket 405 is slidably connected to the inner wall of the mounting groove 302. The edge of the hatch 401 and the inner wall of the first inlet and outlet 403 are both stepped structures. The installation of the sealing gasket 405 facilitates the sliding installation of the hyperbaric oxygen chamber 2 and the fixed box 301, ensuring that the gap between the first inlet and outlet 403 and the second inlet and outlet 404 can be kept sealed. Conversely, the hyperbaric oxygen chamber 2 will leak out. The stepped structure design of the edge of the hatch 401 and the inner wall of the first inlet and outlet 403 makes the hatch 401 and the first inlet and outlet 403 close tightly and also plays a positioning role.

[0033] Specifically, such as Figure 2 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, each of the two hatches 401 is equipped with a locking mechanism 5 for controlling the opening and closing of the fixed box 301. The locking mechanism 5 includes a lock groove 501. Lock grooves 501 are respectively provided at the center of one side of each of the two first inlets / outlets 403. Locking pins 502 are respectively installed at the center line of the interior of one end of each of the two hatches 401. The locking pins 502 are slidably connected to the interior of the hatches 401 via a return spring 507. One end of the locking pin 502 extends to the outside of the hatches 401 and engages with the interior of the lock groove 501. The other end of the locking pin 502 has a hemispherical structure. Drive discs 503 are rotatably connected to the interior of each of the two hatches 401 via rotating shafts 504. Both ends of the two rotating shafts 504 extend to the outside of the hatches 401 and are connected to two handles 402. The handles 402 are rotatably connected to the outside of the hatches 401 via rotating shafts 504. Symmetrically distributed drive grooves 505 are provided on the outside of the drive discs 503. The other end of the locking pin 502 abuts against the outside of the drive discs 503. The installation of 03 facilitates the contact of the other end of the locking pin 502. The locking pin 502 overcomes the elastic force of the return spring 507 and slides out, inserting into the locking groove 501, thereby locking the hatch 401 and the fixed box 301. By turning the handle 402, the handle 402 drives the rotating shaft 504 to rotate the drive disc 503 by 90 degrees. At this time, the drive groove 505 on the drive disc 503 is located at the end of the locking pin 502. Under the contact of the return spring 507, the locking pin 502 returns to its original position and slides back to its original position. The end of the locking pin 502 slides into the drive groove 505, separating the locking pin 502 from the lock groove 501, making it easy to open the hatch 401 by pulling the handle 402. When the hatch 401 is closed, by rotating the drive disc 503 90 degrees in the opposite direction, since the other end of the locking pin 502 is a hemispherical structure, the drive groove 505 can smoothly slide out against the locking pin 502, so that the locking pin 502 can overcome the elastic force of the return spring 507 and insert into the lock groove 501 to achieve locking.

[0034] Specifically, such as Figure 9 As shown, the drive disc 503 has symmetrical positioning grooves 506 on its outer side. The angle between the two positioning grooves 506 and the two drive grooves 505 is 90 degrees. The inner diameter of the positioning groove 506 is much smaller than the inner diameter of the drive groove 505. By opening the positioning groove 506, when the locking pin 502 is in the locked state, the other end of the locking pin 502 is located inside the positioning groove 506, which plays a role in positioning the drive disc 503 and preventing the drive disc 503 from rotating at will, thus affecting the opening and closing of the hatch 401.

[0035] Specifically, such as Figure 6 , Figure 7 and Figure 8As shown, each of the two hatches 401 is equipped with a sealing mechanism 6 for maintaining a seal with the fixed box 301. The sealing mechanism 6 includes a sealing ring 601. The sealing ring 601 is engaged with the outer steps of each of the two hatches 401. The sealing ring 601 has a frame structure and abuts against the inner wall of the first inlet / outlet 403. The two hatches 401 are equipped with control components for controlling the expansion of the sealing ring 601. The installation of the sealing ring 601 facilitates the sealing ring 601 to abut against the inner wall of the first inlet / outlet 403 after the hatches 401 and the first inlet / outlet 403 are closed, thus achieving a sealing effect and ensuring that the gas inside the hyperbaric oxygen chamber 2 will not leak out. With the cooperation of the control components, the expansion of the sealing ring 601 when the hatches 401 are locked increases the sealing effect.

[0036] Specifically, such as Figure 7 , Figure 8 and Figure 9 As shown, the control assembly includes a connecting pipe 602, an airbag 603, a pressure block 604, a drive rod 605, and a compression spring 606. An airbag 603 is installed inside each of the two hatches 401, and the connecting pipe 602 connects the airbag 603 to the sealing ring 601. A drive rod 605 is installed inside each of the two hatches 401, and the drive rod 605 is slidably connected to the interior of the hatch 401 via the compression spring 606. One end of the drive rod 605 has a hemispherical structure and abuts against the positioning groove 506 on the outer side of the drive disc 503. The other end of the drive rod 605 is equipped with a pressure block 604, which abuts against one end of the airbag 603. The installation of the airbag 603, in conjunction with the connecting pipe 602, facilitates the operation of the sealing ring. Excess gas is stored in 601, which simultaneously connects the airbag 603 and the sealing ring 601. When the drive disc 503 locks the locking pin 502, the drive disc 503 abuts against the drive rod 605. The drive rod 605 slides away from the elastic force of the compression spring 606 and drives the pressure block 604 to compress the airbag 603, causing the gas inside the airbag 603 to enter the sealing ring 601 and expand, increasing the sealing performance of the hatch 401. When the drive disc 503 rotates 90 degrees to release the locking pin 502, the drive rod 605 slides into the drive groove 505 under the resistance of the compression spring 606. At this time, the pressure block 604 contracts without external resistance, the airbag 603 resets, and the sealing ring 601 contracts, making it easier to open the hatch 401.

[0037] Specifically, such as Figure 4 , Figure 5 and Figure 10As shown, the top of the hyperbaric oxygen chamber 2 is equipped with suspension mechanisms 7 at both ends for easy connection to an external crane. The suspension mechanism 7 includes connecting blocks 704. Connecting blocks 704 are installed inside both ends of the hyperbaric oxygen chamber 2. The top of the hyperbaric oxygen chamber 2 is provided with two through slots 702. The tops of the two connecting blocks 704 extend into the through slots 702. Pull rings 703 are rotatably connected to the tops of the two connecting blocks 704. The installation of the connecting blocks 704 facilitates the connection of the pull rings 703. The opening of the through slots 702 facilitates the extension of the connecting blocks 704 into the through slots 702, making the pull rings 703 exposed. At the same time, it is convenient to store the pull rings 703 when not in use. The installation of the two pull rings 703 facilitates the suspension with the external crane rope, making it easy to lift the hyperbaric oxygen chamber 2 with the crane and realize the assembly and disassembly of the hyperbaric oxygen chamber 2.

[0038] Specifically, such as Figure 1 , Figure 2 , Figure 5 and Figure 10 As shown, two sliding plates 701 are slidably connected to the top of the two through slots 702 respectively. The sliding plates 701 have an "L" shape structure. One end of the bottom of the sliding plate 701 is slidably connected to the inside of the hyperbaric oxygen chamber 2. The length of the bottom of the sliding plate 701 is greater than the length of the through slot 702. A telescopic spring 705 is connected between the bottom of the connecting block 704 and the hyperbaric oxygen chamber 2. The connecting block 704 is slidably connected to the inner side of the top of the hyperbaric oxygen chamber 2 through the telescopic spring 705. The installation of the sliding plate 701 helps to cover the through slot 702 and hide the pull ring 703. By sliding the sliding plate 701, the pull ring 703 is exposed for use. The installation of the telescopic spring 705 helps to pull the connecting block 704, causing the connecting block 704 to slide down, thus hiding the pull ring 703 inside the through slot 702. By pulling the pull ring 703, the connecting block 704 is freed from the elastic force of the telescopic spring 705 and slides out, making it easy for the pull ring 703 to be exposed and connected to the external pull rope.

[0039] Specifically, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 10As shown, limiting mechanisms 8 for limiting the movement between the hyperbaric oxygen chamber 2 and the fixed box 301 are respectively installed on the inner sides of both ends of the top of the hyperbaric oxygen chamber 2. The limiting mechanism 8 includes a limiting rod 801. Symmetrical limiting rods 801 are respectively installed on the inner sides of both ends of the top of the hyperbaric oxygen chamber 2. The limiting rods 801 are slidably connected to the inside of the hyperbaric oxygen chamber 2 through a contact spring 803. The bottom outer side of the connecting block 704 is provided with a groove 804. The two reinforcing ribs 303 are respectively provided with limiting grooves 802 corresponding to the limiting rods 801 on opposite sides. One end of the limiting rod 801 extends to the outside of the hyperbaric oxygen chamber 2 and engages with the limiting groove 802. The other end of the limiting rod 801 is a hemispherical structure. The other end of the limiting rod 801 abuts against the outside of the connecting block 704. The groove 804 is located at the bottom of the limiting rod 801. When the connecting block 704 is pulled down by the telescopic spring 705, the outer side of the connecting block 704 abuts against the limiting rod 801. The limiting rod 801 then slides out of the contact spring 803 and inserts into the limiting groove 802, thus limiting the hyperbaric oxygen chamber 2 and the fixed box 301 and stabilizing the installation of the hyperbaric oxygen chamber 2. When it is necessary to lift and disassemble the hyperbaric oxygen chamber 2, the connecting block 704 is pulled by the pull ring 703. The connecting block 704 slides upward a certain position, freeing itself from the telescopic spring 705. The groove 804 on the outer side of the connecting block 704 aligns with the limiting rod 801. At this time, the limiting rod 801 slides under the elastic force of the contact spring 803 and slides into the groove 804, separating from the limiting groove 802. This facilitates the release of the limiting between the hyperbaric oxygen chamber 2 and the fixed box 301, making disassembly and assembly easier.

[0040] In use, this invention first uses fasteners to detachably install the fixed box 301 to the vehicle body 1. This detachment facilitates subsequent maintenance. The mounting groove 302 facilitates the sliding connection between the hyperbaric oxygen chamber 2 and the fixed box 301, further simplifying disassembly and maintenance. The hyperbaric oxygen chamber 2, mounted on the vehicle body 1 between the cab and the cargo box, protects the chamber while allowing drivers to access it from the cab. The reinforcing ribs 303 reinforce both ends of the fixed box 301. The guide groove 304, with the reinforcing ribs 303, guides the disassembly and assembly of the hyperbaric oxygen chamber 2. The connecting block 704 facilitates the connection of the pull ring 703. The through groove 702 facilitates... The connecting block 704 extends into the through groove 702, exposing the pull ring 703 and facilitating its storage when not in use. The installation of two pull rings 703 facilitates suspension with external crane ropes, allowing the hyperbaric oxygen chamber 2 to be lifted and disassembled. The installation of the sliding plate 701 conceals the through groove 702, hiding the pull ring 703. Sliding the sliding plate 701 exposes the pull ring 703 for use. The installation of the telescopic spring 705 allows the connecting block 704 to be pulled, causing it to slide down and conceal the pull ring 703 within the through groove 702. Pulling the pull ring 703 releases the tension of the telescopic spring 705, allowing the pull ring 703 to be exposed. When connected to an external pull rope, the connecting block 704 is pulled down by the telescopic spring 705. The outer side of the connecting block 704 abuts against the limiting rod 801, causing the limiting rod 801 to slide out from the abutting spring 803 and insert into the limiting groove 802. This limits the position between the hyperbaric oxygen chamber 2 and the fixed box 301, ensuring stable installation of the hyperbaric oxygen chamber 2. When it is necessary to lift and disassemble the hyperbaric oxygen chamber 2, the connecting block 704 is pulled by the pull ring 703. The connecting block 704 slides upward a certain position, freeing itself from the telescopic spring 705. The groove 804 on the outer side of the connecting block 704 aligns with the limiting rod 801. At this time, the limiting rod 801 slides under the elastic force of the abutting spring 803, sliding into the groove 804 and separating from the limiting groove 802, facilitating the lifting and disassembly of the hyperbaric oxygen chamber 2. The barrier between the hyperbaric oxygen chamber 2 and the fixed container 301 is removed for easy assembly and disassembly. The two second inlets / outlets 404 facilitate personnel access to the hyperbaric oxygen chamber 2. The two first inlets / outlets 403 connect the first and second inlets / outlets 403 and 404 after the hyperbaric oxygen chamber 2 is installed with the fixed container 301, allowing personnel to enter and exit the hyperbaric oxygen chamber 2 from the driver's cab or outside the vehicle, making access more convenient. The two first inlets / outlets 403 of different sizes facilitate personnel access from the driver's cab and outside the vehicle. The installation of the hatch 401 facilitates the opening and closing of the two first inlets / outlets 403, ensuring personnel access and safety. The installation of the handle 402 facilitates control of the opening and closing of the hatch 401. The installation of the sealing gasket 405...After the hyperbaric oxygen chamber 2 is slidably installed inside the fixed box 301, the gap between the first inlet / outlet 403 and the second inlet / outlet 404 is kept sealed. Conversely, the hyperbaric oxygen chamber 2 will leak out. The stepped structure design of the edge of the door 401 and the inner wall of the first inlet / outlet 403 ensures a tight seal between the door 401 and the first inlet / outlet 403, and also serves as a positioning function. The installation of the drive disc 503 facilitates the contact of the other end of the locking pin 502. The locking pin 502 overcomes the elastic force of the return spring 507 and slides out, inserting into the lock groove 501, thereby locking the door 401 and the fixed box 301. By turning the handle 402, the handle 402 drives the rotating shaft 504 to engage the drive disc 504. 03. Rotate 90 degrees. At this time, the drive groove 505 on the drive disc 503 is located at the end of the locking pin 502. Under the resistance of the return spring 507, the locking pin 502 returns to its original position and slides. The end of the locking pin 502 slides into the drive groove 505, separating the locking pin 502 from the locking groove 501. This facilitates opening the hatch 401 by pulling the handle 402. After the hatch 401 is closed, by rotating the drive disc 503 90 degrees in the opposite direction, since the other end of the locking pin 502 is a hemispherical structure, the drive groove 505 can smoothly resist and slide out of the locking pin 502. This allows the locking pin 502 to overcome the elastic force of the return spring 507 and insert into the locking groove 501, achieving locking. Through the opening of the positioning groove 506, the locking pin 502... When locked, the other end of the locking pin 502 is located inside the positioning groove 506, which positions the drive disc 503 and prevents it from rotating arbitrarily, thus affecting the opening and closing of the hatch 401. The installation of the sealing ring 601 ensures that after the hatch 401 is closed with the first inlet / outlet 403, the sealing ring 601 contacts the inner wall of the first inlet / outlet 403, providing a seal and preventing gas leakage from the hyperbaric oxygen chamber 2. Through the cooperation of the control components, the sealing ring 601 expands when the hatch 401 is locked, increasing the sealing effect. The installation of the airbag 603, in conjunction with the connecting pipe 602, facilitates the storage of excess gas in the sealing ring 601, while simultaneously allowing the airbag 603 to... The door 401 is connected to the sealing ring 601. When the drive disc 503 locks the locking pin 502, the drive disc 503 abuts against the drive rod 605. The drive rod 605 slides away from the elastic force of the compression spring 606, and the drive rod 605 drives the pressure block 604 to compress the airbag 603, causing the gas inside the airbag 603 to enter the sealing ring 601 and expand, increasing the sealing performance of the hatch 401. When the drive disc 503 rotates 90 degrees to release the locking pin 502, the drive rod 605 slides into the drive groove 505 under the resistance of the compression spring 606. At this time, the pressure block 604 contracts without external resistance, the airbag 603 resets, and the sealing ring 601 contracts, making it easier to open the hatch 401.
