[0002] At present, micro-hyperbaric oxygen chambers are gradually entering everyday households, and there are more and more application scenarios. The principle of the micro-hyperbaric oxygen chamber is to increase the body's oxygen intake by providing a high concentration of pure oxygen and a trace positive pressure environment to improve the effect of oxygen therapy. The interior of the micro-hyperbaric oxygen chamber is usually a sealed cabin, with a door as its entrance and exit. The door is subjected to the dual test of high strength and self-weight and high pressure in the cabin, which is far from being comparable to ordinary car doors and home doors. The gap between the door and the cabin will affect the cabin's sealing and the smoothness of opening and closing the door. The factors that affect the door gap are comprehensive, such as the hatch frame accuracy, cabin shaft seat accuracy, hinge shaft installation adjustment, door accuracy, etc., so the importance of adding an adjustment mechanism to the door is becoming more and more prominent. Utility Model Content

DETAILED DESCRIPTION
[0020] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0021] Example 1
[0022] See also Figures 1 to 3This embodiment provides an oxygen chamber with a cantilevered outward-opening door multi-directional adjustment mechanism, the oxygen chamber includes a chamber body, a hatch (not shown in the figure) is provided on the chamber body, a rotating shaft 1 is provided at the hatch, a cantilever 2 is installed on the rotating shaft 1, a door 3 matching the hatch is installed at one end of the cantilever 2 through a swivel 4, the door 3 is made of transparent material, and the door 3 is set to an outward-opening door structure. The cantilever 2 is provided with a door up and down adjustment mechanism, and the swivel 4 is provided with a door left and right push mechanism.
[0023] Specifically, the hatch door up and down adjustment mechanism is used to adjust the up and down position of the hatch door 3. Specifically, the hatch door up and down adjustment mechanism includes an adjustment block 21 and an adjustment bolt 22. The adjustment block 21 fits tightly with the adjustment bolt 22, and the adjustment block 21 is a wedge-shaped adjustment block. A rotating shaft bottom sleeve 12 is fixed on the rotating shaft 1. The rotating shaft bottom sleeve 12 is a wedge-shaped rotating shaft bottom sleeve that cooperates with the adjustment block 21. The adjustment block 21 and the adjustment bolt 22 are in contact with the rotating shaft bottom sleeve 12. The rotating shaft bottom sleeve 12 and the rotating shaft 1 remain stationary.
[0024] Here, a positioning ring 23 is sleeved on the top of the adjustment bolt 22, and the positioning ring 23 is installed on the surface of the cantilever 2 and locks the position of the adjustment bolt 22. A thread is arranged inside the adjustment block 21, and the adjustment bolt 22 rotates through the thread to displace the wedge-shaped adjustment block 21, so that the cantilever 2 in contact with the wedge-shaped adjustment block 21 is displaced up and down, thereby driving the hatch 3 to displace up and down relative to the hatch, that is, to achieve fine adjustment of the hatch up and down.
[0025] In addition, a rotating shaft top sleeve 11 is provided on the end of the rotating shaft 1 opposite to the rotating shaft bottom sleeve 12 , and the rotating shaft top sleeve 11 is tightly matched with the rotating shaft 1 .
[0026] The left and right push mechanism of the hatch provided in this embodiment comprises a long hole 43, a push column 41, and a push block 24. The swivel 4 drives the hatch 3 to move and adjust in the left and right directions in the long hole 43. The hatch 3 is provided with a push block 24, one end of the push column 41 is connected to the push block 24, and the other end of the push column 41 has a thread. Accordingly, a nut is fixed at one end of the swivel connected to the push column 41, and the push column 41 is connected to the swivel through the nut.
[0027] There are one or more long holes 43, and one or more swivel fixing bolts 42 are provided on the swivel 4. The number of the swivel fixing bolts 42 corresponds to the number of the long holes 43. The swivel fixing bolts 42 are installed in the long holes 43, and the swivel fixing bolts 42 fix the swivel 4 along the left and right directions of the long holes 43. That is, after the swivel 4 drives the hatch 3 to adjust the hatch 3 to align with the hatch center along the left and right directions of the long holes 43, the swivel fixing bolts 42 are tightened and fixed in the long holes 43, and the top column 41 is tightened at the same time, so that the push block 24 supports the swivel 4. At this time, the fixed swivel fixing bolts 42 and the push block 24 can limit the swivel 4 from driving the hatch 3 to move left and right along the long holes 43.
[0028] In other embodiments, the hatch door up and down adjustment mechanism can also be implemented by installing a gasket on the shaft 1 after removing the hatch door 3 to adjust the height of the hatch door 3, so as to adjust the up and down position of the hatch door 3 relative to the cantilever 2. The hatch door left and right push mechanism can also be implemented by installing a bolt stopper on the swivel fixing bolt 42 to achieve left and right adjustment of the hatch door. However, the present invention is not limited to this.
[0029] The working principle of the utility model is:
[0030] A top sleeve 11 is provided at one end of the rotating shaft 1 to closely match the rotating shaft 1, and a bottom sleeve 12 is provided at the other end to match the wedge-shaped adjustment block 21 in the cantilever 2, and the rotating shaft 2 and the bottom sleeve 12 are fixed. When adjusting the hatch up and down, the adjustment bolt 22 is rotated, and the wedge-shaped adjustment block 21 moves along the width direction of its wedge shape. According to the lever principle, the hatch 3 swings up and down in the opposite direction, thereby adjusting the hatch 3 up and down. The hatch up and down adjustment mechanism can realize the operation of adjusting the hatch 3 up and down without disassembling any parts.
[0031] The hatch 3 is fixed to the swivel 4 of the cantilever 2 and a hatch left and right push mechanism is set. When in use, the top column 41 is rotated, and the hatch 3 is adjusted to the center position of the hatch in the left and right direction through the swivel fixing bolt 42, that is, after the top column 41 pushes the push block 24, the top column 41 is rotated in the opposite direction to complete the left and right displacement of the swivel 4 relative to the cantilever 2, that is, the left and right stepless limit of the left and right movement of the hatch 3 is completed. This design can prevent the hatch 3 from moving through the swivel fixing bolt 42. After the adjustment is completed, the hatch 3 will not be displaced in the left and right direction under pressure.
[0032] Therefore, the hatch door 3 can be adjusted up and down steplessly through the hatch door up and down adjustment mechanism, and can be adjusted left and right steplessly through the swivel fixing bolt 42 and the hatch door left and right pushing mechanism, which can avoid problems such as sealing leakage caused by uneven hatch door gaps and abnormal switch noises. At the same time, it provides a safety threshold for the comprehensive tolerances of the cabin body, hatch door, and mounting axle seat, improves the pass rate of oxygen cabin doors, reduces costs, and increases profits.
[0033] In summary, the above-mentioned implementation modes are not limitative implementation modes of the present invention, and any modification or equivalent deformation made by technicians in this field on the basis of the essential content of the present invention is within the technical scope of the present invention.
