Description

Technical Field

[0001] The utility model relates to the technical field of hyperbaric oxygen chambers, in particular to an automatic lifting threshold of a hyperbaric oxygen chamber. Background Technique

[0002] A hyperbaric oxygen chamber is a special 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 application range of the hyperbaric oxygen chamber is very wide, and it is mainly used clinically for the treatment of anaerobic infections, CO poisoning, air embolism, decompression sickness, ischemic hypoxic encephalopathy, brain trauma, cerebrovascular diseases, etc.

[0003] To ensure the sealing performance during use, most of the cabin doors of the hyperbaric oxygen chamber are set to be inwardly flip - type. When closed, the cabin door will flip and sink into the groove to ensure that the high pressure inside the oxygen chamber is tightly attached to the door frame. At the threshold position of the groove, when people enter the oxygen chamber, it is easy to have the phenomenon of stepping into the air, which has certain potential safety hazards. Content of the Utility Model

[0004] The purpose of the utility model is to provide an automatic lifting threshold for a hyperbaric oxygen chamber to solve the problems raised in the above - mentioned background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An automatic lifting threshold of a hyperbaric oxygen chamber, including the base of the hyperbaric oxygen chamber. At the top edge of the base of the hyperbaric oxygen chamber, there is a door frame wall. One side of the door frame wall is hinged with a cabin door. At the position near the bottom of the cabin door on the top of the base of the hyperbaric oxygen chamber, there is an installation groove, and a lifting plate is arranged at the position of the installation groove.

[0006] Preferably, at the four corner positions at the bottom end of the lifting plate, there are four damping rods. The bottom ends of the four damping rods are jointly connected with a bottom plate. A sliding groove is opened at the top end of the bottom plate. Two adjusting plates are arranged at the bottom end of the lifting plate. The bottom plate is fixedly installed inside the base of the hyperbaric oxygen chamber. The damping rods support the four corners of the lifting plate to ensure that the lifting plate does not tilt when moving linearly up and down.

[0007] Preferably, the lifting plate is adapted to the installation groove, and the lifting plate can move linearly up and down inside the installation groove. When the lifting plate descends, the cabin door can sink into the installation groove and fit with the sealing strip at the corresponding position of the door frame wall. When the cabin door is opened and rises, the lifting plate rises, and the top end of the lifting plate is flush with the top end of the base of the hyperbaric oxygen chamber, covering the installation groove, which is convenient for people to enter the hyperbaric oxygen chamber without stepping into the air.

[0008] Preferably, one side of each of the two adjusting plates is provided with an inclined groove. Rollers are installed inside the two inclined grooves. The inclined direction of the inclined groove is upwardly inclined at the rear end, and horizontal buffer grooves are provided at both ends of the inclined groove. When the rollers linearly move from the front end to the rear end in the inclined groove, the adjusting plate is driven to linearly move downward through the inclined groove. When the rollers linearly move from the rear end to the front end in the inclined groove, the adjusting plate is driven to linearly move upward through the inclined groove.

[0009] Preferably, alloy columns are provided on one side of each of the two rollers. The ends of the two alloy columns are jointly connected to an adjusting base. An electric push rod is provided at the rear end of the adjusting base. An installation bracket is provided at the rear end of the electric push rod. The bottom end of the installation bracket is installed on the top end of the bottom plate. The alloy columns have high hardness and good load-bearing effect. The electric push rod drives the adjusting base to perform linear forward and backward movement. When the adjusting base performs linear movement, the alloy columns drive the rollers to perform linear movement in the inclined groove.

[0010] Preferably, four limiters are provided at the top ends of the bases at both ends of each of the two adjusting plates. Two limiters form a group. The two limiters in each group clamp the front end and the rear end of the bottom of the adjusting plate, so that the adjusting plate will not tilt during the up and down linear movement.

[0011] Compared with the prior art, the beneficial effects of the present utility model are:

[0012] For the automatic lifting threshold of this hyperbaric oxygen chamber, when the electric push rod pushes the adjusting base to linearly move forward, when the adjusting base performs linear movement, the alloy columns drive the rollers to linearly move forward in the inclined groove. When the rollers linearly move from the front end to the rear end in the inclined groove, the adjusting plate is driven to linearly move downward through the inclined groove. When the output end of the electric push rod stops running, the rollers are in the buffer groove of the parallel device provided at the front end of the inclined groove, and the lifting plate is driven to rise. The top end of the lifting plate is flush with the top end of the base of the hyperbaric oxygen chamber, covering the installation groove, facilitating personnel to enter the hyperbaric oxygen chamber, preventing the personnel using the hyperbaric oxygen chamber from tripping over the installation groove when entering the oxygen chamber, improving safety, and at the same time preventing the dust on the soles of the feet from falling onto the sealing strip.

[0020] As Figures 1 to 4 shown, the automatic lifting threshold of the hyperbaric oxygen chamber in this embodiment includes a base 1 of the hyperbaric oxygen chamber. A doorframe wall 4 is provided at the top edge of the base 1 of the hyperbaric oxygen chamber. A cabin door 3 is hingedly installed on one side of the doorframe wall 4. In order to improve the sealing performance of the hyperbaric oxygen chamber, the cabin door 3 is opened towards the inside of the hyperbaric oxygen chamber. When the hyperbaric oxygen chamber is in use, the cabin door 3 is closed, and the inside of the hyperbaric oxygen chamber is pressurized, so that a pressure difference is formed on both sides of the cabin door 3, and the cabin door 3 is pressed tightly against the sealing strip on the doorframe wall 4 to form a seal. An installation groove 2 is provided at the top of the bottom plate 7 near the bottom of the cabin door 3. When the cabin door 3 is closed, the cabin door 3 will drop into the installation groove 2, so that the cabin door 3 fits the sealing strip on the lower side wall of the doorframe wall 4. A lifting plate 5 is provided at the position of the installation groove 2. When the cabin door 3 is closed, the lifting plate 5 drops to ensure that the cabin door 3 can sink into the installation groove 2. When the cabin door 3 is opened, the lifting plate 5 rises to cover the installation groove 2, facilitating personnel to enter the hyperbaric oxygen chamber.

[0021] Specifically, four damping rods 6 are provided at the four corner positions at the bottom end of the lifting plate 5. The bottom ends of the four damping rods 6 are jointly connected to a bottom plate 7. A chute 11 is opened at the top end of the bottom plate 7. Two adjusting plates 8 are provided at the bottom end of the lifting plate 5. The bottom plate 7 is fixedly installed inside the hyperbaric oxygen chamber base 1. The damping rods 6 support the four corners of the lifting plate 5 to ensure that the lifting plate 5 does not tilt when performing up and down linear motion.

[0022] Furthermore, the lifting plate 5 is adapted to the installation groove 2. The lifting plate 5 can perform up and down linear motion inside the installation groove 2. When the lifting plate 5 descends, the cabin door 3 can sink into the installation groove 2 and fit with the sealing strip at the corresponding position of the door frame wall 4. When the cabin door 3 is opened by rising, the lifting plate 5 rises, and the top end of the lifting plate 5 is flush with the top end of the hyperbaric oxygen chamber base 1 to cover the installation groove 2, facilitating personnel to enter the hyperbaric oxygen chamber without stepping into the void.

[0023] Furthermore, inclined slots 10 are formed through one side of the two adjusting plates 8. Two rollers 12 are installed inside the two inclined slots 10. The inclined direction of the inclined slots 10 is upwardly inclined at the rear end, and buffer slots in a horizontal state are provided at both ends of the inclined slots 10. When the rollers 12 perform linear motion from the front end to the rear end in the inclined slots 10, the adjusting plates 8 are driven to perform downward linear motion through the inclined slots 10. When the rollers 12 perform linear motion from the rear end to the front end in the inclined slots 10, the adjusting plates 8 are driven to perform upward linear motion through the inclined slots 10.

[0024] Furthermore, alloy columns 13 are provided on one side of each of the two rollers 12. The ends of the two alloy columns 13 are jointly connected to an adjusting base 16. An electric push rod 14 is provided at the rear end of the adjusting base 16. An installation bracket 15 is provided at the rear end of the electric push rod 14. The bottom end of the installation bracket 15 is installed at the top end of the bottom plate 7. The alloy columns 13 have high hardness and good load-bearing effect. The electric push rod 14 drives the adjusting base 16 to perform forward and backward linear motion. When the adjusting base 16 performs linear motion, the alloy columns 13 drive the rollers 12 to perform linear motion in the inclined slots 10.

[0025] Even further, four limiters 9 are provided at the top end of the bottom plate 7 at both ends of the two adjusting plates 8. Two limiters 9 are in a group. Each group of two limiters 9 clamp the front end and the rear end of the bottom of the adjusting plate 8 to ensure that the adjusting plate 8 does not tilt when performing up and down linear motion.

[0026] The usage method of this embodiment is as follows: When the hatch door 3 is opened, the hatch door 3 first rises and then flips towards the interior of the hyperbaric oxygen chamber. At this time, the electric push rod 14 pushes the adjustment base 16 to move linearly forward. When the adjustment base 16 moves linearly, the alloy column 13 drives the roller 12 to move linearly forward in the inclined groove 10. When the roller 12 moves linearly from the front end to the rear end in the inclined groove 10, the adjustment plate 8 is driven to move linearly downward through the inclined groove 10. When the output end of the electric push rod 14 stops running, the roller 12 is in the buffer groove of the parallel device provided at the front end of the inclined groove 10, and the lifting plate 5 is driven to rise. The top of the lifting plate 5 is flush with the top of the hyperbaric oxygen chamber base 1, covering the installation groove 2, facilitating personnel to enter the hyperbaric oxygen chamber without stepping into the void. Before closing the hatch door 3, the electric push rod 14 will pull the adjustment base 16 to move linearly backward. The roller 12 moves linearly from the front end to the rear end in the inclined groove 10, and the adjustment plate 8 is driven to move linearly downward through the inclined groove 10, causing the lifting plate 5 to descend. When closing the hatch door 3, the hatch door 3 will descend into the installation groove 2, making the hatch door 3 fit the sealing strip on the lower side wall of the door frame wall 4.
