[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model provides a technical solution: a self-opening quick-locking device for a hyperbaric oxygen chamber door, including a hyperbaric oxygen chamber body 1, a door body 2 movably installed on one side of the hyperbaric oxygen chamber body 1, a PLC controller 3 fixedly installed on one side of the door body 2, and an automatic locking mechanism 4 provided on one side of the door body 2.

[0025] The automatic locking mechanism 4 includes a limiting sliding groove 401. A limiting sliding groove 401 is formed on one side of the hatch body 2. A drive motor 402 is fixedly installed on the inner wall of one side of the limiting sliding groove 401. The drive motor 402 is electrically connected to the PLC controller 3. A limiting protective block 403 is fixedly installed at the output end of the drive motor 402. An adjusting screw 404 is fixedly installed on the side of the limiting protective block 403 away from the drive motor 402. A movable connecting block 405 is fixedly installed on the inner wall of the limiting sliding groove 401 on the side away from the drive motor 402. The side of the adjusting screw 404 away from the limiting protective block 403 is rotatably connected to the side of the movable connecting block 405. The adjusting screw 404 is threadedly connected to a positioning sliding screw block 406 at its outer end. A support mounting block 407 is fixedly installed on one side of the positioning sliding screw block 406. A locking rod 408 is fixedly installed on one side of the support mounting block 407. An installation support block 409 is fixedly installed on one side of the hyperbaric oxygen chamber 1. A locking tube 410 is fixedly installed on the side of the installation support block 409 away from the hyperbaric oxygen chamber 1. The locking rod 408 is movably connected to the locking tube 410. When the drive motor 402 is started, the adjusting screw 404 is rotated, causing the positioning sliding screw block 406 to move linearly on the adjusting screw 404, thereby driving the locking rod 408 to be accurately inserted into the locking tube 410 for locking.

[0026] A movable hinge 5 is threadedly connected to one side of the hyperbaric oxygen chamber body 1 and the door body 2. An entrance / exit opening 6 is provided on one side of the hyperbaric oxygen chamber body 1. A limiting frame 7 is fixedly installed on the inner wall of the entrance / exit opening 6. A limiting sealing groove 8 is provided on the side of the limiting frame 7 near the door body 2. A sealing ring 9 is fixedly installed on the side of the door body 2 near the hyperbaric oxygen chamber body 1. The sealing ring 9 is movably connected to the limiting sealing groove 8. The sealing ring 9 is squeezed into the limiting sealing groove 8, and the sealing ring 9 and the limiting sealing groove 8 fit tightly together to form an effective sealing structure.

[0027] Working principle: When it is necessary to lock the hatch body 2, the hatch body 2 is first pushed closer to the hyperbaric oxygen chamber body 1 under the action of the movable connecting hinge 5 and finally closed. As the hatch body 2 moves, the sealing ring 9 gradually approaches the limiting sealing groove 8. As the hatch closes, the sealing ring 9 is squeezed into the limiting sealing groove 8, and the sealing ring 9 and the limiting sealing groove 8 fit tightly together to form an effective sealing structure. This tight-fitting sealing method can effectively prevent the high-pressure gas inside the hyperbaric oxygen chamber body 1 from leaking from the connection between the hatch and the chamber body, providing a reliable sealing guarantee for maintaining a specific high-pressure state inside the hyperbaric oxygen chamber, ensuring that the hyperbaric oxygen chamber can maintain its high-pressure state. The system operates safely and stably. Subsequently, the PLC controller 3 starts the drive motor 402 to rotate the adjusting screw 404. As the adjusting screw 404 rotates, the positioning sliding block 406, which is threaded to it, moves linearly along the axial direction of the adjusting screw 404 within the limiting sliding groove 401. The movement of the positioning sliding block 406 drives the support mounting block 407, which is fixedly connected to it, to move synchronously. This causes the locking rod 408 to be accurately inserted into the locking tube 410 on the mounting support block 409, completing the locking action between the hatch body 2 and the hyperbaric oxygen chamber body 1. This achieves the automatic locking operation of the hatch and facilitates the unlocking operation later.

[0028] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
