Description

Technical Field

[0001] This application belongs to the field of micro-pressure oxygen chamber technology, and in particular relates to a door hinge for a micro-pressure oxygen chamber. Background Technology

[0002] A microbaric oxygen chamber uses breathable gases such as air, oxygen, or a mixture of gases as the pressure medium, creating a chamber pressure 0-30 kPa higher than the outside atmospheric pressure. It offers benefits such as relieving fatigue, assisting in disease treatment, promoting microcirculation, aiding recovery, and regulating immunity. The amount of dissolved oxygen in human blood is related to environmental pressure. Living in an environment with one atmosphere of pressure, where oxygen is only about 1 / 5 of that in the air, results in relatively low levels of both bound and dissolved oxygen in the blood. In a microbaric oxygen chamber with a pressure of 1.3 atmospheres, both bound and dissolved oxygen levels in the human body are increased, especially dissolved oxygen, which increases by 110%. This effectively improves the oxygen demand of human tissues and organs, enhances the body's immune system, allows cells to fully utilize nutrients, activates cells, regulates the autonomic nervous and endocrine systems, enhances the body's self-regulation ability, effectively accelerates the metabolism of fatigue-causing substances, reduces muscle and tendon tension, relieves nervous tension, improves athletic performance, increases the body's oxygen reserves, increases oxygen concentration in brain cells, enhances memory, improves mental state, alleviates sleep disorders, and improves sleep quality. Therefore, the micro-pressure oxygen chamber came into being. The micro-pressure oxygen chamber greatly increases the dissolved oxygen content in the blood of the user inside the chamber by pressurizing and oxygenating.

[0003] Because the cabin needs to be sealed and pressurized, there are higher requirements for the cabin door. The cabin door of a micro-pressure oxygen chamber is generally made of transparent acrylic material, but it is thicker than ordinary acrylic material. In addition, in order to eliminate or reduce pressure, the cabin door is generally rounded. The cabin door is opened and closed using hinges, but traditional hinges are generally limited in installation methods, have insufficient load-bearing capacity, are simple and unsightly in appearance, and are difficult to rotate under certain gravity conditions. Some hinges are installed with multiple hinges to distribute the load, but long-term opening and closing may cause wear and tear on the hinges.

[0004] For example, patent CN223089206U discloses a fully transparent oxygen chamber door structure. The main body of the door is connected to the chamber body by a hinge. It can be seen that the contact area between the hinge structure and the door is small, and the rotation position is only achieved by the hinge structure at both ends of the hinge pin. Long-term opening and closing will cause the door and the hinge to be not firmly connected, and the hinge and the hinge pin to be misaligned. Ultimately, the door will move severely and cannot be opened and closed smoothly, affecting the sealing effect of the micro-pressure oxygen chamber. Summary of the Invention

[0005] This application provides a door hinge for a micro-pressure oxygen chamber, which solves the problem of insufficient hinge load-bearing capacity and difficulty in rotation under certain gravity conditions.

[0006] This application provides a door hinge for a micro-pressure oxygen chamber, including a fixed component and a rotating component, which are rotatably connected. The rotating component is provided with a bearing assembly, which drives the fixed component to rotate.

[0007] In one embodiment, The bearing assembly includes an upper bearing assembly and a lower bearing assembly; The upper bearing assembly, from top to bottom, includes a snap ring, a first bearing, a first spacer, and a second bearing. The lower bearing assembly, from top to bottom, includes a third bearing, a second spacer, a fourth bearing, and a nut.

[0008] In one embodiment, The rotating assembly includes a fixed base plate, with mounting plates on both sides of the fixed base plate.

[0009] In one embodiment, A pin is mounted through the mounting plate, and a rotating shaft is fitted around the outer circumference of the pin.

[0010] In one embodiment, The snap ring, the first bearing, the first spacer, the second bearing, the third bearing, the second spacer, and the fourth bearing are all fitted onto the pin.

[0011] In one embodiment, The mounting plate has mounting holes.

[0012] In one embodiment, One end of the pin is equipped with a bolt, and the other end is equipped with a protrusion. The bolt and nut are fitted together.

[0013] In one embodiment, The length of the rotating shaft is less than the length of the pin.

[0014] In one embodiment, The fixed assembly includes a hatch connecting plate, with side plates on both sides of the hatch connecting plate. The side plates have assembly holes with the diameter of the assembly holes matching the diameter of the pin.

[0015] In one embodiment, A reinforcing plate is provided between the side panels, and the reinforcing plate is fixedly connected to the hatch connecting plate.

[0016] This application provides a door hinge for a micro-pressure oxygen chamber. Multiple bearings are installed at the top and bottom of the pin and rotating shaft, supporting the rotation of the shaft and reducing the coefficient of friction during its movement. Additionally, the circlip, in conjunction with the bearings, ensures the rotational accuracy of the shaft, allowing the micro-pressure oxygen chamber door to open and close easily. The multiple bearings distribute the force, extending the hinge's service life. The addition of a reinforcing plate increases the hinge's load-bearing capacity, preventing wear and deformation even after prolonged use. This prevents the door from shifting, ensuring a better seal and improving user comfort. The hinge is simple to install, reliably fixed, has a high load-bearing capacity, and boasts an aesthetically pleasing appearance. Attached Figure Description

[0020] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, this application will be further described in detail. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.

[0021] In one embodiment, a micro-pressure oxygen chamber door hinge includes a fixed component and a rotating component, which are rotatably connected. The rotating component is provided with a bearing assembly, which drives the fixed component to rotate.

[0022] Specifically, the fixing component is used to fix the hinge to the micro-pressure oxygen chamber door, and the rotating component realizes the hinge, making the micro-pressure oxygen chamber door easy to open and close.

[0023] In one embodiment, such as Figure 1 As shown, the rotating assembly includes a fixed base plate 1, with a mounting plate 2 on one side of the fixed base plate 1. The number of mounting plates 2 is at least one; in this embodiment, there are two. The two mounting plates 2 are respectively mounted on the same side ends of the fixed base plate 1. The two mounting plates 2 have mounting holes, namely a protrusion mounting hole 31 and a nut mounting hole 32. The rotating assembly also includes a pin 5, as shown... Figure 2 As shown, the pin 5 is cylindrical. One end of the pin 5 is provided with a bolt 52 that mates with the nut mounting hole 32, and the other end is provided with a protrusion 51 that mates with the protrusion mounting hole 31. A rotating shaft 4 is sleeved on the outer periphery of the pin 5, and the length of the rotating shaft 4 is less than the length of the pin 5.

[0024] Specifically, the fixed base plate 1 has multiple fixing holes 10, which are used to fix the fixed base plate 1 to the micro-pressure oxygen chamber; the protrusion mounting hole 31 and the nut mounting hole 32 are different in size, the diameter of the protrusion 51 is larger than the diameter of the protrusion mounting hole 31, and the diameter of the bolt 52 is smaller than the diameter of the protrusion mounting hole 31 and the nut mounting hole 32. The protrusion 51 and the bolt 52 fix the pin 5 between the two side plates 2; the length of the pin 5 is greater than the distance between the two mounting plates 2. The pin 5 is used to connect the fixed component and the rotating component. The pin 5 is also used to install the bearing assembly. The rotating shaft 4 is used to fix the component to rotate around the pin 5.

[0025] In one embodiment, the bearing assembly includes an upper bearing assembly A disposed at the upper end of the rotating shaft 4 and a lower bearing assembly B disposed at the lower end of the rotating shaft 4, such as... Figure 3 As shown, the upper bearing assembly A, from top to bottom, includes a retaining ring 11, a first bearing 121, a first spacer 131, and a second bearing 122, as follows: Figure 4 As shown, the lower bearing assembly B, from top to bottom, includes the third bearing 123, the second spacer 132, the fourth bearing 14, and the nut 15; the snap ring 11, the first bearing 121, the first spacer 131, the second bearing 122, the third bearing 123, the second spacer 132, and the fourth bearing 14 are all engaged with the pin 5, and the nut 15 is engaged with the bolt 52.

[0026] Specifically, the snap ring 11, the first bearing 121, the first spacer 131, the second bearing 122, the third bearing 123, the second spacer 132, and the fourth bearing 14 all have round holes with the same diameter as the pin 5, so that the snap ring 11, the first bearing 121, the first spacer 131, the second bearing 122, the third bearing 123, the second spacer 132, and the fourth bearing 14 can be fitted onto the pin 5; the diameter of the nut 15 is larger than the diameter of the nut mounting hole 32; the snap ring 11 is used to fasten the first bearing 121 and the second bearing 122; the first bearing 121, the second bearing 122, the third bearing 123, and the fourth bearing 14 are all used to support the rotation of the rotating shaft 4; and the first spacer 131 and the second spacer 132 are used to mate with the bearings.

[0027] In one embodiment, the fixing component includes a hatch connecting plate 6, with side plates 9 on both sides of the hatch connecting plate 6. The side plates 9 have assembly holes 8, the diameter of which matches the diameter of the pin 5. A reinforcing plate 7 is provided between the side plates 9, and the reinforcing plate 7 is fixedly connected to the hatch connecting plate 6.

[0028] Specifically, the door connecting plate 6 is also provided with multiple fixing holes 10. The fixing holes 10 are used to fix the door connecting plate 6 to the micro-pressure oxygen chamber door. In this embodiment, the micro-pressure oxygen chamber door is made of transparent acrylic material, which is lighter than the metal door, which can reduce the load on the hinge and extend the service life of the hinge. The pressure range inside the micro-pressure oxygen chamber is generally 10-30 kPa, or even higher. The acrylic door and hinge provided in this application have undergone multiple pressure resistance tests and can fully meet the pressure of 10-150 kPa. There are no abnormal noises in the micro-pressure oxygen chamber, and there is no visible deformation of the door and hinge. The rotating shaft 4 is hollow inside, and the diameter of the hollow part is the same as the diameter of the assembly hole 8. The side plate 9, the door connecting plate 6 and the reinforcing plate 7 are connected to the rotating shaft 4 by welding. The pin 5 passes through the assembly hole 8, the rotating shaft 4, the protrusion mounting hole 31 and the nut mounting hole 32 to hinge the side plate 9 to the mounting plate 2.

[0029] like Figure 5 As shown, this is the assembled door hinge. Figure 6 As shown, the door connecting plate 6 is fixed to the micro-pressure oxygen chamber door with screws, and the fixing base plate is fixed to the micro-pressure oxygen chamber body, thus realizing the hinge connection between the chamber body and the door; the sealing and locking of the micro-pressure oxygen chamber are existing technologies and will not be described in detail here.

[0030] This application provides a door hinge for a micro-pressure oxygen chamber, including a fixed component and a rotating component, which are rotatably connected. The rotating component is equipped with a bearing assembly, which drives the fixed component to rotate. This application reduces the coefficient of friction during the rotation of the rotating shaft by setting multiple bearings at the top and bottom of the pin and the rotating shaft. Furthermore, the circlip, in cooperation with the bearings, ensures the rotational accuracy of the rotating shaft, thus ensuring easy opening and closing of the micro-pressure oxygen chamber door. The multiple bearings distribute the force, extending the hinge's service life. The addition of a reinforcing plate increases the hinge's load-bearing capacity, preventing wear and deformation even after prolonged use, preventing door movement and displacement, and improving the door's sealing effect and user comfort. The hinge is simple to install, has a reliable fixing method, high load-bearing capacity, and an aesthetically pleasing appearance.
