Description

Technical Field

[0001] The utility model relates to the technical field of hinge structures, in particular to a mechanical structure of a hinge assembly for an oxygen cabin. Background Art

[0002] The oxygen chamber is a special medical device for hyperbaric oxygen therapy. According to the different pressurized media, it is divided into two types: air pressurized chamber and pure oxygen pressurized chamber. The hinge assembly mechanical structure is also called the hinge structure. It is a very common auxiliary component in the opening and closing process of the oxygen chamber door. It is usually used to connect the cabin body and the door panel so that the door panel can rotate around the axis to realize the opening and closing function of the oxygen chamber. It is a mechanical connection method widely used in various fields. Its working principle is based on the principle of force balance and material mechanics.

[0003] During the use of the oxygen chamber, when the hinge mechanism is needed for assistance, the hinge plate is first fixed to the oxygen chamber door, and then the hinge gasket is fixed to the oxygen chamber body. Then, when the oxygen chamber door is opened and closed, the hinge plate rotates along the hinge gasket, and then assists the staff to open the oxygen chamber door and allow people to enter the oxygen chamber for recuperation; but during the use of the micro-pressure oxygen chamber, when the cabin body changes from normal air pressure to pressurized air, the cabin door needs to be manually pulled hard by someone outside the cabin, or manually pushed hard inside the cabin to ensure the sealing of the cabin door so that pressure can be applied. Moreover, during the repeated use of most oxygen chambers on the market, the hinge shaft is usually in an immovable state, which may cause the hinge assembly to have a slight deformation, and then cause the original oxygen chamber door position to shift, losing the original sealing effect with the cabin body, resulting in the oxygen chamber door being unable to seal normally. Utility Model Content

[0004] The purpose of the utility model is to provide a hinge assembly mechanical structure for an oxygen chamber to solve the problems raised by the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mechanical structure of a hinge assembly for an oxygen chamber, comprising a hinge plate, a hinge shaft and a hinge pad, wherein the hinge plate is connected to the hinge shaft through an insertion hole, and hinge washers are sleeved on both sides of the outer wall of the hinge shaft, and the hinge shaft is connected to the hinge pad through a long through hole.

[0006] Preferably, the outer wall of the hinge pad is connected to the aerobic chamber body, and the outer wall of the hinge plate is connected to the aerobic chamber body.

[0007] Preferably, a through hole is formed on the outer wall of the hinge pad, and a mounting cavity corresponding to the hinge pad is formed on one side of the outer wall of the hinge plate.

[0008] Preferably, the hinge plate and the hinge pad are both chrome-plated, and the hinge pad is connected to the oxygen chamber body by bolts.

[0009] Preferably, an auxiliary mechanism is provided inside the hinge plate, and the auxiliary mechanism includes a storage cavity, a lubricating sponge and an introduction hole, and storage cavities are opened on both sides inside the hinge plate.

[0010] Preferably, a lubricating sponge is connected to the interior of the storage cavity, and an introduction hole is opened on one side of the hinge plate close to the lubricating sponge.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: when the mechanical structure of the hinge assembly for the oxygen chamber is in use, the deformation of the hinge assembly is reduced as much as possible by allowing the hinge shaft to move slightly along the long through hole, thereby greatly extending the service life of the hinge assembly, and during the oxygen chamber pressure and decompression process, the sealing state of the oxygen chamber door and the oxygen chamber body is ensured to be stable at all times, thereby facilitating the prevention of deformation of the hinge assembly and stabilizing the seal, and the auxiliary mechanism can be used to lubricate the hinge shaft when the oxygen chamber door is opened and closed daily to prevent the hinge assembly from getting stuck and affecting the opening and closing of the oxygen chamber door, thereby facilitating lubrication and preventing sticking when the mechanical structure of the hinge assembly for the oxygen chamber is in use.

[0012] 1. When the oxygen chamber is in use and the hinge mechanism is needed for assistance, when the oxygen chamber door is opened and closed, the hinge plate rotates along the hinge axis. At this time, the hinge axis moves slightly along the long through hole, so that the hinge axis is movable in the vertical direction of the oxygen chamber door. Then, through the mobility of the hinge axis, the deformation of the hinge assembly is reduced or eliminated as much as possible, which greatly prolongs the service life of the hinge assembly. In addition, during the oxygen chamber pressure and decompression process, the sealing state of the oxygen chamber door and the oxygen chamber body is ensured to be stable. Therefore, when the mechanical structure of the hinge assembly for the oxygen chamber is used, it is convenient to prevent the deformation of the hinge assembly and stabilize the seal;

[0013] 2. When the oxygen cabin is in use and the hinge mechanism is needed for assistance, the lubricating oil is first introduced into the lubricating sponge in the storage chamber through the introduction hole. Then, when the oxygen cabin door is opened and closed daily, the hinge shaft will squeeze the lubricating sponge, causing the lubricating oil to flow out to lubricate the hinge shaft, thereby preventing the hinge assembly from getting stuck and affecting the opening and closing of the oxygen cabin door. Then, when the oxygen cabin door is opened and closed daily, the lubrication of the hinge shaft can be completed, saving time and energy, thereby facilitating lubrication and preventing sticking when the mechanical structure of the hinge assembly is used in the oxygen cabin.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-Figure 8 The utility model provides a technical solution: a mechanical structure of a hinge assembly for an oxygen cabin, comprising a hinge plate 1, a hinge shaft 2 and a hinge pad 4, wherein the hinge plate 1 is connected with the hinge shaft 2 through an insertion hole, and hinge washers 3 are sleeved on both sides of the outer wall of the hinge shaft 2, and the hinge shaft 2 is connected with the hinge pad 4 through a long through hole 5; the outer wall of the hinge pad 4 is connected with the oxygen cabin body 6, and the outer wall of the hinge plate 1 is connected with the oxygen cabin body 6; a through hole is provided on the outer wall of the hinge pad 4, and a mounting cavity corresponding to the hinge pad 4 is provided on one side of the outer wall of the hinge plate 1; the hinge plate 1 and the hinge pad 4 are both chrome-plated, and the hinge pad 4 is connected to the oxygen cabin body 6 by bolts; a long through hole 5 corresponding to the hinge shaft 2 is provided inside the hinge pad 4, the hinge pad 4 is slidably connected to the hinge shaft 2, the hinge shaft 2 and the hinge washer 3 are through-connected, and the hinge plate 1 is fixedly connected to the oxygen cabin door 7 by screws.

[0025] In specific implementation, when the oxygen chamber is in use and the hinge mechanism is required to assist, in order to solve the problem that the sealed door and the chamber body are not tightly sealed and difficult to seal when the oxygen chamber is pressurized, the hinge shaft 2 is first passed through the hinge gasket 3, the hinge pad 4 and the hinge plate 1 in sequence, and then the hinge pad 4 is fixed to the oxygen chamber body 6. After that, when the oxygen chamber door 7 is opened and closed, the hinge plate 1 rotates along the hinge shaft 2. Since a long through hole 5 corresponding to the hinge shaft 2 is opened inside the hinge pad 4, the hinge shaft 2 moves slightly along the long through hole 5 at this time, so that the hinge shaft 2 is very flexible when rotating and has mobility in the direction perpendicular to the oxygen chamber door 7;

[0026] The movability of the hinge shaft 2 greatly reduces or even eliminates the hard connection of the hinge assembly and the deformation of the oxygen chamber during pressure increase and decompression, and ensures that the sealing state of the oxygen chamber door 7 and the oxygen chamber body 6 is always stable during the pressure increase and decompression of the oxygen chamber and the entire working process. Therefore, when the oxygen chamber is pressurized and decompressed, the sealing of the door and the chamber body is faster and more labor-saving, and during the repeated use of the oxygen chamber, the deformation of the hinge assembly is reduced or eliminated as much as possible, which greatly prolongs the service life of the hinge assembly. When the mechanical structure of the hinge assembly is used in the oxygen chamber, it is convenient to prevent the deformation of the hinge assembly and stabilize the seal.

[0027] See also Figure 1-Figure 3 , Figure 4 and Figure 5 It can be seen that an auxiliary mechanism 8 is provided inside the hinge plate 1, and the auxiliary mechanism 8 includes a storage cavity 801, a lubricating sponge 802 and an introduction hole 803. Storage cavities 801 are opened on both sides inside the hinge plate 1; the storage cavity 801 is connected to the lubricating sponge 802, and an introduction hole 803 is opened on one side of the hinge plate 1 close to the lubricating sponge 802; the storage cavity 801 is located close to the hinge gasket 3, and the storage cavity 801 is connected to the introduction hole 803.

[0028] In specific implementation, when the hinge mechanism is needed to assist during the use of the oxygen chamber, as the use time increases, in order to ensure the flexibility of the hinge plate 1 when rotating and prevent it from getting stuck and affecting the daily opening and closing of the oxygen chamber door 7, when the hinge shaft 2 needs to be lubricated, since an introduction hole 803 is provided on one side of the hinge plate 1 close to the storage chamber 801, the lubricating oil is first introduced into the storage chamber 801 through the introduction hole 803, so that the lubricating sponge 802 in the storage chamber 801 is soaked with the lubricating oil;

[0029] Furthermore, when the oxygen cabin door 7 is opened and closed daily, the hinge shaft 2 will move, and then squeeze the lubricating sponge 802, so that the lubricating oil in the lubricating sponge 802 flows out to lubricate the hinge shaft 2, thereby preventing the hinge assembly from getting stuck and affecting the opening and closing of the oxygen cabin door 7. Furthermore, there is no need to disassemble the hinge assembly. The lubrication of the hinge shaft 2 can be completed when the oxygen cabin door 7 is opened and closed daily, saving time and energy. When the mechanical structure of the hinge assembly for the oxygen cabin is used, it plays a role in facilitating lubrication and preventing jamming.

[0030] In summary, when the mechanical structure of the hinge assembly for the oxygen chamber is used, the hinge plate 1 is first fixed to the oxygen chamber door 7, and then the hinge pad 4 is fixed to the oxygen chamber body 6. Then, when the oxygen chamber door 7 is opened and closed, the hinge plate 1 rotates along the hinge gasket 3, and then the auxiliary staff opens the oxygen chamber door 7 to allow people to enter the oxygen chamber for recuperation. This is a prior art and will not be elaborated on here. By allowing the hinge shaft 2 to move slightly along the long through hole 5, the deformation of the hinge assembly is reduced as much as possible, the service life of the hinge assembly is greatly extended, and in the oxygen chamber During the process of pressure increase and decompression, the sealing state of the oxygen chamber door 7 and the oxygen chamber body 6 is ensured to be stable at all times. The hinge shaft 2 can be lubricated by the auxiliary mechanism 8 when the oxygen chamber door 7 is opened and closed daily to prevent the hinge assembly from getting stuck and affecting the opening and closing of the oxygen chamber door 7. In addition, the hinge assembly has a compact structure, is easy to use, has a low cost, is highly safe, has multiple functions, a wide range of applications, and a long service life. It greatly facilitates operators and provides more guarantees for the safety of users.
