Description

Technical Field

[0001] The utility model relates to the technical field of hyperbaric oxygen chambers, in particular to a door sealing mechanism of a hyperbaric oxygen chamber. Background Art

[0002] A hyperbaric oxygen chamber is a specialized medical device used for treatment. It provides oxygen concentrations above atmospheric pressure in a pressurized environment to promote oxygen absorption by the patient's tissues. It is used to treat various hypoxic diseases, wound healing, and burn recovery. The safety and effectiveness of a hyperbaric oxygen chamber depends heavily on its sealing performance, especially under high pressure, where maintaining a good seal is crucial.

[0003] Traditional hyperbaric oxygen chamber door sealing technology primarily relies on sealing strips made of rubber or other elastic materials to achieve sealing. However, in low-temperature environments, these sealing materials tend to harden, resulting in a reduction in their elasticity, which in turn affects sealing performance. Furthermore, due to the high pressure inside the hyperbaric oxygen chamber, if the sealing strips lose their elasticity in low-temperature conditions, it can lead to a poor seal, which in turn can cause oxygen leakage, affecting treatment effectiveness and even endangering patient safety. Existing hyperbaric oxygen chamber door sealing mechanisms often make it difficult to quickly remove and replace the sealing strips, which is not only time-consuming but can also damage the equipment during disassembly and assembly, increasing maintenance costs and downtime. Therefore, a hyperbaric oxygen chamber door sealing mechanism is needed to address these issues. Utility Model Content

[0004] The purpose of the utility model is to provide a hatch sealing mechanism for a hyperbaric oxygen chamber, which has the advantages of good sealing effect at low temperatures and is easy to disassemble and repair. It solves the problem that traditional sealing strips are easily hardened in low temperature environments, resulting in a decrease in sealing performance, affecting the airtightness and safety of the hyperbaric oxygen chamber, and the traditional sealing mechanism is more complicated when repairing and replacing the sealing strips, which increases the difficulty and cost of maintenance.

[0008] As a preferred hatch sealing mechanism of a hyperbaric oxygen chamber of the present invention, the outer end of the guide rod is sleeved with a compression spring, the side of the guide rod is provided with a limiting flange, and the guide rod is elastically connected to the knob through the compression spring.

[0009] As a preferred embodiment of the hatch sealing mechanism of a hyperbaric oxygen chamber of the present invention, the back side of the fixing frame is provided with anti-slip serrations.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. The utility model sets a heating mechanism between the door body and the sealing strip. The heating mechanism can work in a low-temperature environment. By heating the sealing strip, the sealing strip is prevented from hardening due to the low temperature, thereby avoiding the sealing failure caused by the loss of elasticity of the sealing strip. Due to the presence of the heating mechanism, the sealing strip can maintain its proper physical properties even in extremely cold climate conditions, ensuring the airtightness of the hyperbaric oxygen chamber, thereby ensuring the stability of the cabin environment and the treatment effect. Good sealing is the basis for the safe operation of the hyperbaric oxygen chamber. The utility model effectively prevents safety hazards such as pressure loss or oxygen concentration drop caused by poor sealing.

[0014] 2. The fixing bracket of the utility model adopts a sliding connection design, and the position can be adjusted by rotating the knob, which makes the inspection and maintenance of the heating wire and the replacement of the sealing strip more convenient and quick. At the same time, the compression spring on the guide rod can automatically pop out after the knob is rotated to a certain position, further simplifying the disassembly and assembly process. The external thread at the end of the guide rod is used in conjunction with the screw hole on the knob to firmly press the sealing strip onto the cabin door body, preventing poor sealing problems caused by loose sealing strips.

[0022] See also Figures 1-6 A door sealing mechanism for a hyperbaric oxygen chamber comprises a door body 1 and a sealing strip 2, wherein a heating mechanism 3 is provided between the door body 1 and the sealing strip 2;

[0023] The heating mechanism 3 includes a fixing frame 301, a heating wire 302 and a heat conducting plate 305. The fixing frame 301 is detachably mounted on the front end face of the hatch body 1. The heat conducting plate 305 is mounted on the front end face of the fixing frame 301. A reinforcing rib 306 is provided between the heat conducting plate 305 and the fixing frame 301. The heating wire 302 is coiled between the fixing frame 301 and the heat conducting plate 305. A card slot 201 cooperating with the fixing frame 301 is provided on the back of the sealing strip 2. The sealing strip 2 is sleeved on the fixing frame 301 through the card slot 201 and is clamped to it.

[0024] By arranging a heating mechanism 3 between the hatch body 1 and the sealing strip 2, the heating mechanism 3 heats the sealing strip 2 in a low-temperature environment to prevent the sealing strip 2 from hardening in a low-temperature environment, affecting the fit between the sealing strip 2 and the oxygen chamber and the hatch, affecting the sealing, and causing insufficient pressure in the oxygen chamber or insufficient oxygen concentration.

[0025] Furthermore, a guide rod 303 is provided on the back of the fixing frame 301 , and a sliding hole 101 cooperating with the guide rod 303 is provided on the door body 1 , and the guide rod 303 is inserted into the sliding hole 101 and is slidably connected with the door body 1 .

[0026] The sliding connection of the fixing frame 301 structure allows it to be disassembled to inspect the internal heating wire 302, which is convenient for replacing the sealing strip 2 and improves the convenience of equipment inspection.

[0027] Furthermore, the end of the guide rod 303 is provided with an external thread, and a sleeve 102 is provided on the back of the hatch body 1. A knob 103 for rotation connection is provided on the sleeve 102, and a screw hole 1031 that cooperates with the guide rod 303 is provided on the front end face of the knob 103.

[0028] By rotating the knob 103 , the fixing frame 301 is fixed, so that the fixing frame 301 gradually presses the sealing strip 2 , thereby completing the fixation of the sealing strip 2 and the fixing frame 301 , avoiding a gap between the sealing strip 2 and the fixing frame 301 and affecting the sealing effect.

[0029] Furthermore, a compression spring 104 is sleeved on the outer end of the guide rod 303 , a limiting flange 304 is provided on the side of the guide rod 303 , and the guide rod 303 is elastically connected to the knob 103 through the compression spring 104 .

[0030] When the knob 103 is rotated until the guide rod 303 is separated from the knob 103, the knob 103 pops out under the action of the compression spring 104, so that the fixing frame 301 slides forward quickly, providing a certain installation space for the installation and removal of the sealing strip 2, thereby improving the convenience of operation.

[0031] Furthermore, anti-slip serrations 307 are provided on the back of the fixing frame 301 .

[0032] The anti-slip serrations 307 enhance the frictional resistance between the fixing frame 301 and the sealing strip 2 bracket, thereby preventing the sealing strip 2 from loosening and falling off, and improving the stability of the sealing strip 2 .

[0033] Furthermore, a cavity 202 is provided in the sealing strip 2 .

[0034] The cavity 202 enhances the elasticity of the sealing strip 2 and improves the fit between the sealing body and the oxygen chamber.

[0035] Furthermore, the heat conducting plate 305 is supported by aluminum alloy, the heating wire 302 is attached to the back surface of the heat conducting plate 305 , and the front end surface of the heat conducting plate 305 is in contact with and connected to the sealing strip 2 .

[0036] The heat generated by the heating wire 302 is evenly conducted to the sealing strip 2 through the heat conducting plate 305, so that the heating wire 302 evenly heats the sealing strip 2, thereby keeping the sealing strip 2 soft in a low temperature environment and preventing the sealing strip 2 from hardening and affecting the sealing effect.

[0037] When using this sealing strip 2, before using it in a low temperature environment, turn on the heating mechanism 3 to ensure that the heating wire 302 is working normally, and transfer the heat to the sealing strip 2 evenly through the heat conducting plate 305 to maintain the softness and elasticity of the sealing strip 2. When the sealing strip 2 is aged and needs to be replaced, turn the knob 103 to slide the guide rod 303 outward until the knob 103 is completely separated from the guide rod 303. When the knob 103 is separated from the guide rod 303, the compression spring 104 will push the fixing frame 301 to slide forward, providing space for disassembling the sealing strip 2. Remove the old sealing strip 2 and replace it with a new sealing strip 2 on the fixing frame 301. Press the sealing strip 2 so that the guide rod 303 squeezes the spring to reach the knob 103, and then tighten each knob 103 in turn until the fixing frame 301 presses the sealing strip 2 to complete the fixation.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
