[0002] A hyperbaric oxygen chamber is a special medical device for hyperbaric oxygen therapy, with a wide range of applications. Clinically, it is mainly used for the treatment of anaerobic infections, CO poisoning, air embolism, decompression sickness, ischemic hypoxic encephalopathy, brain trauma, cerebrovascular diseases, etc.
[0003] At present, hyperbaric oxygen chambers are not only used in hospitals, but also can be used at home or by firefighters. At present, the switch handle of the hyperbaric oxygen chamber door is installed on the door body, and there are the following defects: (1) The rigidity of the door body is insufficient, and the sealing structure is limited by space. After repeated opening / closing operations, air leakage is likely to occur at the handle rotation shaft; (2) The handle on the inner side of the door body not only affects the entry and exit of personnel from the chamber, but also, after closing, the handle on the inner side corresponds to the widest part of the upper body of the user, occupying a certain space inside the oxygen chamber and affecting comfort; (3) When opening a hole in the door body, due to space limitations, it is difficult to strengthen the structure. The opening not only reduces the strength due to local stress, but also is prone to deformation, posing a certain safety hazard in a high-pressure use environment; in addition, when using a hyperbaric oxygen chamber, how to quickly and safely lock the oxygen chamber door is also a technical problem to be overcome.
[0004] In view of this, it is necessary to develop a door for a hyperbaric oxygen chamber. Summary of the Invention
[0005] In order to solve the above technical problems, the purpose of the utility model is to disclose a door of a hyperbaric oxygen chamber.
[0006] To achieve the above invention purpose, the utility model provides a door of a hyperbaric oxygen chamber, including a chamber body and a door body hinged to the chamber body; a door frame matching the door body is arranged on the chamber body;
[0007] A number of intermittently arranged lock blocks are arranged along the inner edge of the door body, and a gap is provided between the lock blocks and the door body;
[0008] A locking ring and a locking switch assembly are arranged on the door frame. A number of intermittently arranged locking teeth are arranged along the edge of the locking ring, and a wedge-shaped surface is arranged at one end of the locking teeth;
[0009] The locking switch assembly drives the locking ring to rotate and drives the locking teeth and the lock blocks to engage;
[0010] The locking switch assembly is arranged on the side of the locking ring. The locking switch assembly includes a first locking handle, a connecting rod and a locking pin. A long strip waist-shaped hole is arranged on the connecting rod.

[0011] Preferably, the lock block is in the shape of a cuboid.
[0012] Preferably, a first gap is provided between adjacent lock blocks, and a second gap is provided between adjacent lock teeth.
[0013] Preferably, when the door body is in an unlocked state, the first gap is aligned with the lock teeth, and the second gap is aligned with the lock block;
[0014] When the door body is in a locked state, the first gap is aligned with the second gap.
[0015] Preferably, a first limit pin is provided on the upper side of the connecting rod, and a second limit pin is provided on the lower side of the connecting rod.
[0016] Preferably, during the process of rotating the first locking handle, the wedge surface first enters the gap and gradually causes the lock teeth and the lock block to engage.
[0017] Preferably, a second locking handle is provided inside the cabin, and the second locking handle rotates around the same rotating shaft as the first locking handle.
[0018] Preferably, a first protrusion and a second protrusion are provided on the side of the locking ring;

[0023] Compared with the prior art, the technical effects of the present utility model are as follows:
[0024] The locking switch assembly of the present utility model is arranged on the side of the door frame. By rotating the first locking handle, the connecting rod is driven to swing, and the long strip waist-shaped hole of the connecting rod drives the locking pin to swing, thereby driving the locking ring to rotate. During the rotation of the locking ring, the wedge-shaped surface first enters the gap and gradually makes the locking teeth and the locking block engage. By rotating the first locking handle, the door body can be quickly locked. After locking, the locking teeth and the locking block are firmly engaged, safe and reliable. The first locking handle of the present utility model is arranged on the cabin body. The structural strength of the cabin body is much greater than that of the door body.

[0039] Embodiment 1
[0040] Refer Figures 1 to 10 As shown, this embodiment discloses a specific implementation of a hyperbaric oxygen chamber door
[0041] Hyperbaric oxygen chamber door, see Figures 1 to 10, including a cabin body 1 and a door body 2 hinged to the cabin body 1; a door frame 3 matching the door body 2 is arranged on the cabin body 1; a number of intermittently arranged lock blocks 21 are arranged along the inner edge of the door body 2, and a gap 211 is arranged between the lock block 21 and the door body 2; a locking ring 31 and a locking switch assembly 32 are arranged on the door frame 3, and a number of intermittently arranged lock teeth 311 are arranged along the edge of the locking ring 31, and a wedge surface 3111 is arranged at one end of the lock tooth 311; the locking switch assembly 32 drives the locking ring 31 to rotate and drives the lock teeth 311 and the lock blocks 21 to engage; the locking switch assembly 32 is arranged on the side of the locking ring 31, and the locking switch assembly 32 includes a first locking handle 321, a connecting rod 322 and a locking pin 323. The first locking handle 321 is arranged on the cabin body 1. A long strip waist-shaped hole 3221 is arranged on the connecting rod 322. One end of the locking pin 323 is installed on the side of the locking ring 31, and the other end of the locking pin 323 moves along the long strip waist-shaped hole 3221.
[0042] Specifically, a hyperbaric oxygen chamber is a special medical device for hyperbaric oxygen therapy, which can be used in hospitals, families and fire brigades. After the door body 2 is closed, the hyperbaric oxygen chamber is filled with high-pressure oxygen, and the inflation stops when the pressure reaches 1.1-1.6 times the external air pressure. To achieve the efficient and safe locking of the door body 2, the lock block 21 is in the shape of a cuboid, a first gap 212 is arranged between adjacent lock blocks 21, and a second gap 312 is arranged between adjacent lock teeth 311; when the door body 2 is in an unlocked state, the first gap 212 is aligned with the lock teeth 311, and the second gap 312 is aligned with the lock block 21, that is, the lock teeth 311 and the lock block 21 are in a staggered state to facilitate the approach of the door body 2 and the door frame 3; when the door body 2 is in a locked state, the first gap 212 is aligned with the second gap 312, and the lock teeth 311 are inserted into the gap 211.
[0043] The working principle of the locking switch assembly 32 is as follows: a first limit pin 33 is arranged on the upper side of the connecting rod 322, and a second limit pin 34 is arranged on the lower side of the connecting rod 322; a first protrusion 313 and a second protrusion 314 are arranged on the side of the locking ring 31; the locking pin 323 is installed on the first protrusion 313; see Figure 5 and Figure 6 , Figure 6 When the first locking handle 321 in Figure 7 and Figure 8, rotate the first locking handle 321 clockwise. During the rotation of the first locking handle 321, the wedge surface 3111 first enters the gap 211 and gradually engages the locking tooth 311 with the locking block 21 through the wedge surface 3111. When the connecting rod 322 is restricted by the second limit pin 34, the locking is completed. A second locking handle 324 is provided in the cabin 1. The second locking handle 324 rotates around the same rotating shaft 325 as the first locking handle 321. After the user completes oxygen inhalation in the cabin 1 and the air pressure in the cabin 1 is reduced to an appropriate range, the user can rotate the second locking handle 324 inside to open the door body 2.
[0044] See Figure 3 , Figure 4 and Figure 10 , when the user is inside the cabin 1, to prevent accidental opening of the door body 2 caused by accidental touching of the handle, a lock hole 3141 is provided on the second protrusion 314; an automatic locking mechanism 4 is provided in the cabin 1. When the door body 2 is in the locked state, the automatic locking mechanism 4 locks the lock hole 3141. Specifically, see Figure 10 , the automatic locking mechanism 4 includes a fixing member 41 and a spring pin 42 disposed inside the fixing member 41. A sealing ring 43 is provided between the spring pin 42 and the fixing member 41. When the door body 2 is in the locked state, oxygen is injected into the cabin 1, so that the air pressure in the cabin 1 gradually becomes greater than the external air pressure. The spring pin 42 extends into the lock hole 3141 under the drive of the air pressure difference and completes the locking of the second protrusion 314. In this case, neither the second locking handle 324 nor the first locking handle 321 can swing; when the user finishes oxygen inhalation and releases the air pressure in the cabin 1, when the air pressure in the cabin 1 is close to the external air pressure, under the action of the spring, the spring pin 42 retracts, unlocking the second protrusion 314. Then the user can open the door body 2 by rotating the second locking handle 324 or the first locking handle 321. Without the automatic locking mechanism 4, the user may open the door body 2 when the pressure is not fully relieved, and under the action of the internal and external pressure difference, the door body 2 may have the risk of being thrown out uncontrollably.
