[0002] A hyperbaric oxygen chamber is a dedicated medical device for hyperbaric oxygen therapy. According to different pressurizing media, it is divided into two types: an air pressurized chamber and a pure oxygen pressurized chamber. The amount of oxygen dissolved in the blood of a normal person is related to the environmental pressure. After multiple experiments, it is concluded that the oxygen dissolved in the blood of a person in a hyperbaric oxygen chamber increases as the pressure of the oxygen chamber increases. After inhaling pure oxygen in an oxygen chamber at 2 atmospheres, the oxygen dissolved in the blood increases by 14 times, and at 3 atmospheres, it increases by 21 times. The hyperbaric oxygen chamber forms a high-pressure environment to increase the dissolved oxygen in the organism for related experiments or treatments.

After the door is closed, it is stuck by the triangular block and the connecting block. Since it is finally fixed by the screw swivel, when someone unscrews the threaded swivel, the threaded swivel and the slide plate are separated. Due to the existence of air pressure, after loosening, the air pressure will push the circular plate, so that the connecting block and the triangular block form a radial force, and the connecting block is stuck by the triangular block. The greater the air pressure, the tighter it is stuck. If an unexpected situation occurs inside the high-pressure hydrogen and oxygen cabin and the door needs to be opened, a hammer or other metal object can be used to knock on the bottom of the slide plate to move the triangular plate upward, so that the second cylinder and the connecting block are not in contact, and the door is opened.

[0007] Preferably, the closing mechanism comprises a circular plate, the outer surface of which is fixedly connected with a handle component, the two ends of the circular plate are rotatably connected with a U-shaped plate, the outer surface of the U-shaped plate is fixedly connected with a wide plate, and a conical hole is opened in the middle of the U-shaped plate, so that the high-pressure hydrogen and oxygen cabin can be closed, and the circular plate is pushed to rotate on the inner wall of the U-shaped plate, so that the rubber ring on the circular plate fits with the wide plate, and the conical barrel fits with the inner wall of the conical hole, the rubber ring is squeezed and deformed, so that the rubber ring fits with the inner wall of the ring groove, and the outer surface of the rubber ring fits with the inner wall of the conical hole to form a closed space, and the locking mechanism is cooperated to form a closed space for the high-pressure hydrogen and oxygen cabin.

[0009] Preferably, the handle member includes a conical column, both ends of the conical column are fixedly connected with half plates, a rubber block is slidably connected to the outer surface of the conical column, a long groove is formed in the outer surface of the rubber block, a wide groove is formed in the outer surface of the rubber block, semi-circular grooves are uniformly formed in the outer surface of the rubber block, and a cleaning member is rotatably connected to the outer surface of the conical column, which facilitates pulling the circular plate easily and avoids slipping during pulling. The diameter of the conical column is thicker at the bottom and thinner at the top, and the rubber block is elastic. The rubber block can be expanded by sliding on the conical column and the elasticity of the rubber block. The diameter of the rubber block becomes larger. The diameter of the rubber block can be adjusted according to the comfort of the user's grip. The fingers are placed through the semi-circular grooves, the palm is placed through the wide groove, and the root of the palm is abutted against the long groove, avoiding slipping caused by sweating on the hand and the like, and being able to pull the circular plate better. Moreover, the rubber material solves the difficulty of difficult grip in cold winter.

[0010] Preferably, the cleaning member includes a ring, a connecting rod is fixedly connected to the outer surface of the ring, a fixing plate is fixedly connected to the end of the connecting rod away from the ring, sponge columns are uniformly arranged at one end of the fixing plate close to the rubber block, and the outer surface of the sponge columns is fixedly connected to one end of the fixing plate close to the rubber plate. A grinding block is fixedly connected to the bottom of the rubber block. Since the high-pressure hydrogen oxygen chamber will be used outdoors and there will be dew adhering in the morning, affecting the operation. By rotating the fixing plate, the semi-circular groove for placing the palm is blocked by the fixing plate to avoid dew adhering to the gripping position. And when the rubber block gets dirty, the fixing plate can be rotated to make the sponge columns contact and rub against the rubber plate to remove the dirt. Moreover, since the conical column will rust after long-term use, making the rubber block slide smoothly, the rusty part can be polished off by the friction between the grinding block and the conical column to ensure the smooth sliding of the rubber block.

Missing grooves are uniformly arranged on the outer surface of the rubber plate, and the middle of the rubber plate is an arc protrusion, which can better seal the high-pressure hydrogen oxygen chamber. After the high-pressure hydrogen oxygen is sealed, pressurization is carried out. The pressure causes the pressing block to be pushed and squeeze the rubber plate.

The rubber plate will contact the wide plate. Under the push of the pressure, the rubber plate fits with the circular plate. The greater the pressure, the tighter the fit, and there is an automatic sealing effect. When the pressing block moves, the side plate moves down, and the bottom plate contacts the missing grooves of the rubber plate and gets stuck with each other. When the circular plate is opened before the air pressure is completely exhausted, the rubber plate will contact the inner wall of the conical hole and generate friction, gradually slowing down the thrust of the air pressure and playing a protective role.

[0014] The beneficial effects of the present invention are as follows: 1. The present invention provides a pre-tightening mechanism so that when the door is opened by mistake, no harm will be caused to the person who opened the door by mistake, and the door can be opened in time when an emergency occurs in the high-pressure hydrogen-oxygen cabin, so that the user of the high-pressure hydrogen-oxygen cabin has an additional safety guarantee. After the door is closed, it is stuck by the triangular block and the connecting block. Since it is finally fixed by the screw cylinder, when someone unscrews the threaded cylinder, the threaded cylinder and the slide plate are separated. Due to the existence of air pressure, after loosening, the air pressure will push the circular plate, so that the connecting block and the triangular block form a radial force, and the connecting block is stuck by the triangular block. The greater the air pressure, the tighter it is stuck. If an unexpected situation occurs inside the high-pressure hydrogen-oxygen cabin and the door needs to be opened, a hammer or other metal object can be used to knock the bottom of the slide plate to move the triangular plate upward, so that the second cylinder and the connecting block are not in contact, and the door is opened.

[0015] 2. The present invention provides a handle component to facilitate the easy opening of the circular plate and avoid slipping when pulling. The diameter of the conical column is thicker at the bottom and thinner at the top, and the rubber block is elastic. The rubber block slides on the conical column. Due to the elasticity of the rubber block, the rubber block can be stretched and the diameter of the rubber block becomes larger. The diameter of the rubber block can be adjusted according to the user's comfort of holding. The fingers are placed in the semicircular groove, the palm is placed in the wide groove, and the base of the palm is pressed against the column by the long groove, so as to avoid slipping caused by sweat on the hands. The circular plate can be better opened, and the rubber material solves the difficulty of palms being difficult to hold in cold winter.

[0016] 3. The present invention provides a cleaning component. Since the high-pressure hydrogen-oxygen chamber will be used outdoors, there will be dew in the morning, which will affect the operation. By rotating the fixing plate, the semicircular groove where the palm is placed is covered by the fixing plate to prevent dew from sticking to the holding position. If the rubber block is dirty, the fixing plate can be rotated to make the sponge column and the rubber plate contact and rub to remove the dirt. Since the conical column will rust after long-term use, making the rubber block slide unsmoothly, the rusty area can be polished off by rubbing the grinding block and the conical column to ensure smooth sliding of the rubber block.

[0017] 4. By setting up a pressing device, the present invention can better seal the high-pressure hydrogen-oxygen chamber. After the high-pressure hydrogen-oxygen is sealed, pressurization is carried out. The pressure causes the pressing block to be pushed and squeeze the rubber plate. The rubber plate is squeezed and deformed, expanding towards the periphery, and its diameter gradually becomes larger than the diameter of the end of the conical barrel far from the circular plate. The rubber plate will contact the wide plate. Under the push of the pressure, the rubber plate fits with the circular plate. The greater the pressure, the tighter the fit, achieving an automatic sealing effect. As the pressing block moves, the side plate moves downwards, and the bottom plate contacts the notch of the rubber plate and they are stuck to each other. When the circular plate is opened before the air pressure is completely exhausted, the rubber plate will contact the inner wall of the conical hole, generating friction, gradually slowing down the thrust of the air pressure and playing a protective role.

[0023] The blocking mechanism 2 includes a long block 21, a slide groove 22 is provided on the outer surface of the long block 21, a slider 23 is slidably connected to the inner wall of the slide groove 22, a threaded screw 24 is threadedly connected to the inner wall of the slider 23, a slide groove 25 is provided on the outer surface of the long block 21, a pre-tightening component 27 is slidably connected to the inner wall of the slide groove 25, and a conical groove 26 is provided at the bottom of the inner wall of the slide groove 25. The circular plate 11 is rotated, and the circular plate 11 and the wide plate 14 are fitted together, and the pre-tightening component 27 and the L-bevel groove 113 opened in the connecting block 112 of the closing mechanism 1 are fitted together. The slide plate 274 can be pulled to slide in the narrow groove 273 by rotating the rotary column, and the triangular plate moves in the L-bevel groove 113 of the connecting block 112. Since the L-bevel groove 113 is a triangle, the closer it moves to one end of the long block 21, the tighter the fit is, squeezing the connecting block 112, driving the circular plate 11 to fit the wide plate 14, and the high-pressure hydrogen and oxygen cabin forms a closed space. The positioning column 272 is conical in shape and fits the conical groove 26, so that the pre-tightening component 27 is fixed in the second slide groove 25 without displacement.

[0024] The pre-tightening component 27 includes a slider 271, a positioning column 272 is fixedly connected to the bottom of the slider 271, a narrow groove 273 is provided on the outer surface of the slider 271, a slider 274 is slidably connected to the inner wall of the narrow groove 273, a fixing ring 275 is evenly arranged on the outer surface of the slider 274, and the outer surface of the slider 274 is fixedly connected to both ends of the fixing ring 275, a steel wire rope 276 is fixedly connected to the outer surface of the fixing ring 275, a cylinder 277 is fixedly connected to the bottom of the slider 274, a triangular block 278 is fixedly connected to the bottom of the cylinder 277, and the outer surface of the triangular block 278 is evenly fixed to the second fixing ring 279.

After closing the hatch, it is stuck by the triangular block 278 and the connecting block 112. Pull the sliding plate 274 to move within the narrow slot 273. The triangular block 278 slides on the inner wall of the L-shaped slot 113 of the connecting slot. The edge of the triangular block 278 will be stuck within the triangular slot 114. Pull the sliding plate 274 through the screw stud, so that the triangular plate and the L-shaped slot 113 are closely attached. Push the sliding plate 274, and the sliding plate 274 cannot slide within the narrow slot 273. When someone unscrews the threaded stud 24, separating the threaded stud 24 from the sliding plate 274. Due to the existence of air pressure, after loosening, the air pressure will push the circular plate 11, causing a radial force to be formed between the connecting block 112 and the triangular block 278. The connecting block 112 is stuck by the triangular block 278. The greater the air pressure, the tighter the clamping. Moreover, the edge of the triangular block 278 is stuck within the triangular slot 114, making it difficult to push the sliding plate 274, providing double insurance.

[0025] The closing mechanism 1 includes a circular plate 11. A handle component 12 is fixedly connected to the outer surface of the circular plate 11. U-shaped plates 13 are rotatably connected to both ends of the circular plate 11. A wide plate 14 is fixedly connected to the outer surface of the U-shaped plate 13. A tapered hole 15 is provided in the middle of the U-shaped plate 13.

[0026] One end of the circular plate 11 away from the handle component 12 is fixedly connected with a rubber gasket 16. One end of the circular plate 11 away from the handle component 12 is fixedly connected with a tapered barrel 17. A pressing component 18 is slidably connected near the central axis of the tapered barrel 17. An annular groove 19 is provided on the outer surface of the tapered barrel 17. A rubber ring 110 is provided on the inner wall of the annular groove 19, and the bottom of the inner wall of the annular groove 19 is in contact with the inner wall of the rubber ring 110. Positioning rods 111 are evenly arranged on the inner wall of the annular groove 19, and both ends of the positioning rods 111 are fixedly connected to the inner wall of the annular groove 19. A connecting block 112 is fixedly connected to the outer surface of the circular plate 11. An L-shaped slot 113 is provided on the outer surface of the connecting block 112. A triangular slot 114 is provided at one end of the L-shaped slot 113 close to the tapered barrel 17.

[0027] The wide plate 14 will be fixed on the high-pressure hydrogen and oxygen cabin. When the high-pressure hydrogen and oxygen cabin is closed, holding the handle component 12 can push the circular plate 11 and pull the circular plate 11 open, push the circular plate 11, so that the rubber ring 110 on the circular plate 11 fits with the wide plate 14, and the cone barrel 17 fits with the inner wall of the cone hole 15. The rubber ring 110 is squeezed and deformed, so that the rubber ring 110 fits with the inner wall of the ring groove 19, and the outer surface of the rubber ring 110 fits with the inner wall of the cone hole 15. The outer surface of the positioning rod 111 is slidably connected to the inner wall of the rubber ring 110, which limits the rubber ring 110 and prevents the rubber ring 110 from running away in the ring groove 19. When the rubber ring 110 and the inner wall of the cone hole 15 fit. The rubber ring 110 will be squeezed. Since the width of the rubber ring 110 is smaller than the width of the annular groove 19, when the rubber ring 110 is squeezed, it will expand to both sides, so that the rubber ring 110 can be fully expanded and will not be squeezed and damaged by the edge of the annular groove 19. The connecting block 112 is locked by the locking mechanism, and the high-pressure hydrogen and oxygen cabin is pressurized. The pressure drives the clamping component 18 to work, and the cone barrel 17 and the cone hole 15 are further closed to form a closed space, so that the high-pressure hydrogen and oxygen cabin is formed into a closed space.

[0028] The handle component 12 includes a conical column 121, and half plates 122 are fixedly connected at both ends of the conical column 121. A rubber block 123 is slidably connected to the outer surface of the conical column 121. A long groove 124 is provided on the outer surface of the rubber block 123, and a wide groove 125 is provided on the outer surface of the rubber block 123. Semicircular grooves 126 are evenly provided on the outer surface of the rubber block 123. A cleaning component 127 is rotatably connected to the outer surface of the conical column 121 to facilitate the round plate 11 to be easily pulled apart and avoid slipping when pulling. The diameter of the conical column 121 is thick at the bottom and thin at the top, and the rubber block 123 is elastic. Sliding on the conical column 121, the rubber block 123 can be stretched due to its elasticity, and the diameter of the rubber block 123 becomes larger. The diameter of the rubber block 123 can be adjusted according to the user's comfort of holding. The fingers are placed through the semicircular groove 126, the palm is placed through the wide groove 125, and the base of the palm is pressed against the column by the long groove 124, so as to avoid slipping caused by sweat on the hands, etc., and the circular plate 11 can be pulled open better. The rubber material solves the difficulty of palm gripping in cold winter. If rust appears on the conical column 121 and the rubber block 123 is dirty, it can be cleaned using the cleaning component 127.

[0029] The cleaning component 127 includes a circular ring 1271, a connecting rod 1272 is fixedly connected to the outer surface of the circular ring 1271, a fixing plate 1274 is fixedly connected to one end of the connecting rod 1272 away from the circular ring 1271, sponge columns 1273 are evenly arranged on one end of the fixing plate 1274 close to the rubber block 123, and one end of the fixing plate 1274 close to the rubber plate 185 is fixedly connected to the outer surface of the sponge column 1273, and a grinding block 1275 is fixedly connected to the bottom of the rubber block 123. Since the high-pressure hydrogen-oxygen chamber will be used outdoors and there will be dew adhering in the morning, which affects the operation. By rotating the fixing plate 1274, the semi-circular groove 126 for placing the palm is blocked by the fixing plate 1274 to prevent dew from adhering to the holding position. And when the rubber block 123 gets dirty, the fixing plate 1274 can be rotated so that the sponge column 1273 contacts and rubs against the rubber plate 185 to remove the dirt. Also, since the conical column 121 will rust after long-term use, making the rubber block 123 slide not smoothly, the rusty part can be polished off by rubbing the grinding block 1275 against the conical column 121 to ensure the smooth sliding of the rubber block 123.

[0030] The pressing component 18 includes a sliding rod 181. One end of the sliding rod 181 away from the conical barrel 17 is fixedly connected with a pressing block 182. The outer surface of the pressing block 182 is fixedly connected with side plates 183. One end of the side plates 183 close to the sliding rod 181 is fixedly connected with a bottom plate 184. One end of the pressing block 182 close to the sliding rod 181 is provided with a rubber plate 185, and one end of the pressing block 182 close to the sliding rod 181 is in contact with the end of the rubber plate 185 away from the sliding rod 181. The outer surface of the rubber plate 185 is evenly provided with notches 186. It can better seal the high-pressure hydrogen-oxygen chamber. After the high-pressure hydrogen-oxygen is sealed, pressurization is carried out. The pressure causes the pressing block 182 to be pushed and squeeze the rubber plate 185. The rubber plate 185 is squeezed and deformed, expanding towards the periphery, and its diameter gradually becomes larger than the diameter of the end of the conical barrel 17 away from the circular plate 11. The rubber plate 185 will contact the wide plate 14. Under the push of the pressure, the rubber plate 185 fits with the circular plate 11. The greater the pressure, the tighter the fit, having an automatic sealing effect. When the pressing block 182 moves, the side plates 183 move downwards, and the bottom plate 184 contacts the notches 186 of the rubber plate 185 and gets stuck with each other. When the circular plate 11 is opened before the air pressure is completely exhausted, the rubber plate 185 will contact the inner wall of the conical hole 15, generating friction, so that the thrust of the air pressure is gradually reduced, playing a protective role. Due to its multiple seals, the requirement for the locking structure will be reduced, and there is no need to apply a large force. Its structure can compensate for the gap by itself. Even if the locking structure wears out after long-term use, it can still have a good sealing effect.

[0031] Embodiment 2, use Figures 1 - 6 A multi-layer locking structure for a high-pressure hydrogen-oxygen chamber door according to an embodiment of the present invention will be described as follows.

[0032] As Figures 1 - 6The present invention shows a multi-layer locking structure of a high-pressure hydrogen and oxygen cabin door. On the basis of the first embodiment, the blocking mechanism 2 includes a long block 21, the outer surface of the long block 21 is provided with a slide groove 22, the inner wall of the slide groove 22 is slidably connected with a slider 23, the inner wall of the slider 23 is threadedly connected with a threaded screw 24, the outer surface of the long block 21 is provided with a slide groove 25, and the inner wall of the slide groove 25 is slidably connected with a pre-tightening component 27, and the bottom of the inner wall of the slide groove 25 is provided with a cone groove 26. The circular plate 11 is rotated, and the circular plate 11 and the wide plate 14 are fitted together, and the pre-tightening component 27 and the L-bevel groove 113 opened in the connecting block 112 of the closing mechanism 1 are fitted together. The slide plate 274 can be pulled to slide in the narrow groove 273 by rotating the rotary column, and the triangular plate moves in the L-bevel groove 113 of the connecting block 112. Since the L-bevel groove 113 is a triangle, the closer it moves to one end of the long block 21, the tighter the fit is, squeezing the connecting block 112, driving the circular plate 11 to fit the wide plate 14, and the high-pressure hydrogen and oxygen cabin forms a closed space. The positioning column 272 is conical in shape and fits the conical groove 26, so that the pre-tightening component 27 is fixed in the second slide groove 25 without displacement.

[0033] The pre-tightening component 27 includes a slider 271, a positioning column 272 is fixedly connected to the bottom of the slider 271, a narrow groove 273 is provided on the outer surface of the slider 271, a slider 274 is slidably connected to the inner wall of the narrow groove 273, a fixing ring 275 is evenly arranged on the outer surface of the slider 274, and the outer surface of the slider 274 is fixedly connected to both ends of the fixing ring 275, a steel wire rope 276 is fixedly connected to the outer surface of the fixing ring 275, a cylinder 277 is fixedly connected to the bottom of the slider 274, a triangular block 278 is fixedly connected to the bottom of the cylinder 277, and the outer surface of the triangular block 278 is evenly fixed to the second fixing ring 279. The outer surface of the triangular block 278 is fixedly connected to the two ends of the fixing ring 279, the outer surface of the triangular block 278 is evenly provided with a limit ring 2710, and the outer surface of the triangular block 278 is fixedly connected to the two ends of the limit ring 2710, the bottom of the triangular block 278 is fixedly connected with a cylinder 2711, the inner wall of the cylinder 2711 is evenly provided with round balls 2712, and the inner wall of the cylinder 2711 is rotatably connected to the outer surface of the round balls 2712. After the hatch is closed, the triangular block 278 and the connecting block 112 are stuck, and the slide plate 274 is pulled to move in the narrow groove 273. The triangular block 278 slides on the inner wall of the L-shaped inclined groove 113 of the connecting groove. The edge of the triangular block 278 is stuck in the triangular groove 114, and the slide plate 274 is pulled by the screw rotating column, so that the triangular plate and the L-shaped inclined groove 113 fit tightly, and the slide plate 274 is pushed. The slide plate 274 cannot slide in the narrow groove 273. When someone unscrews the threaded rotating column 24, the threaded rotating column 24 is screwed. 24 and the slide plate 274 are separated. Due to the existence of air pressure, after loosening, the air pressure will push the circular plate 11, so that the connecting block 112 and the triangular block 278 form a radial force, and the connecting block 112 is stuck by the triangular block 278. The greater the air pressure, the tighter the block, and the edge of the triangular block 278 is stuck in the triangular groove 114, and it is difficult to push the slide plate 274, which plays a double insurance role. In case of emergency, such as fire, the hatch door needs to be opened in time, and a hammer or other metal object can be used to knock The bottom of the slide plate 274 is hit, so that the second slide block 271 slides upward in the second slide groove 25. Since the slide block 1 23 and the slide plate 274 are connected by the threaded screw 24, the second slide block 271 slides, and the first slide block 23 also slides in the first slide groove 22. When the triangle plate slides in the L-shaped inclined groove 113 until it is not in contact, the second slide column will slide in the L-shaped inclined groove 113, and the ball 2712 will help it to slide better. When the second column 2711 is not in contact with the connecting block 112, the circular plate 11 is not bound. , can be opened to provide timely assistance to the personnel in the high-pressure hydrogen and oxygen cabin. Since the cylinder 2711 is not fixed, after the circular plate 11 is closed and pressurized, the force on the connecting block 112 will act on the triangular block 278. In order to prevent the triangular block 278 from being severely deformed, the triangular plate is connected through the fixing ring 1 275 and the fixing ring 2 279 through the wire rope 276, and the triangular block 278 is pulled to ensure that it will not be deformed. The limit ring 2710 ensures that the wire rope 276 will not move at will.

[0034] The closing mechanism 1 comprises a circular plate 11 , a handle part 12 is fixedly connected to the outer surface of the circular plate 11 , U-shaped plates 13 are rotatably connected to both ends of the circular plate 11 , a wide plate 14 is fixedly connected to the outer surface of the U-shaped plate 13 , and a conical hole 15 is opened in the middle of the U-shaped plate 13 .

[0035] One end of the circular plate 11 away from the handle member 12 is fixedly connected with a rubber gasket 16. One end of the circular plate 11 away from the handle member 12 is fixedly connected with a conical barrel 17. A pressing member 18 is slidably connected near the central axis of the conical barrel 17. An annular groove 19 is formed on the outer surface of the conical barrel 17. A rubber ring 110 is arranged on the inner wall of the annular groove 19, and the bottom of the inner wall of the annular groove 19 is in contact with the inner wall of the rubber ring 110. Positioning rods 111 are uniformly arranged on the inner wall of the annular groove 19, and the two ends of the positioning rods 111 are fixedly connected with the inner wall of the annular groove 19. A connecting block 112 is fixedly connected to the outer surface of the circular plate 11. An L-shaped inclined groove 113 is formed on the outer surface of the connecting block 112. A triangular groove 114 is formed at one end of the L-shaped inclined groove 113 close to the conical barrel 17.

[0036] The wide plate 14 is fixed on the high-pressure hydrogen oxygen chamber. When closing the high-pressure hydrogen oxygen chamber, hold the handle member 12, and the circular plate 11 can be pushed and pulled away. Push the circular plate 11 to make the rubber ring 110 on the circular plate 11 fit with the wide plate 14, and the conical barrel 17 fits with the inner wall of the conical hole 15. The rubber ring 110 is squeezed and deformed, so that the rubber ring 110 fits with the inner wall of the annular groove 19, and the outer surface of the rubber ring 110 fits with the inner wall of the conical hole 15. The outer surface of the positioning rod 111 is slidably connected with the inner wall of the rubber ring 110, which plays a role in limiting the rubber ring 110 to prevent the rubber ring 110 from running off in the annular groove 19. When the rubber ring 110 fits with the inner wall of the conical hole 15. The rubber ring 110 will be squeezed. Since the width of the rubber ring 110 is smaller than the width of the annular groove 19, when the rubber ring 110 is squeezed, it will expand to both sides, so that the rubber ring 110 expands fully and will not be damaged by the edge of the annular groove 19. Lock the connecting block 112 through the locking mechanism, pressurize the high-pressure hydrogen oxygen chamber, and the pressure pushes the pressing member 18 to work, further closing the conical barrel 17 and the conical hole 15 to form a sealed space, and forming a sealed space for the high-pressure hydrogen oxygen chamber.

[0037] The specific working process is as follows: During work, when in use, hold the rubber block 123 by hand to push the circular plate 11 and the wide plate 14 to fit. The L-shaped inclined groove 113 of the connecting block 112 fits with the triangular block 278, pull the sliding plate 274, rotate the threaded screw 24 to fix the circular plate 11 by the pre-tightening member 27. After pressurizing in the chamber, the pressure will push the pressing block 182 to make the rubber plate 185 deformed and fit with the wide plate 14. After the work is completed, rotate the threaded screw 24, push the sliding plate 274 to make the triangular block 278 not fit with the L-shaped inclined groove 113, and pull the handle member 12 to make the circular plate 11 not fit with the wide plate 14.
