Description

Technical Field

[0001] This utility model relates to a shared locking device for the pull rod and door of a hyperbaric oxygen chamber, belonging to the technical field of locking devices. Background Technology

[0002] Hyperbaric oxygen chambers play an important role in treatment and are increasingly widely used. During use, the internal oxygen pressure of a hyperbaric oxygen chamber is extremely high. When a gap appears in the movable door (2), oxygen leakage occurs inside the chamber, reducing the therapeutic effect.

[0003] Chinese Patent Publication No. CN 216725063 U discloses a shared locking device for the drawbars and door of a hyperbaric oxygen chamber, relating to the field of medical devices. The device includes a chamber body and a front end cover and a rear end cover installed at both ends of the chamber body. A door is installed on the outer end face of the front end cover. Several drawbars are evenly arranged inside the chamber body, with threaded ends. The ends of the drawbars are fixedly connected to the rear end cover via nuts. A through hole is provided on the front end cover for the front ends of the drawbars to pass through. A shared locking nut is threaded to the front ends of the drawbars, and a circular groove is provided on the outer end face of the front end cover to mate with the shared locking nut. Several door fixing holes are provided on the door opposite the drawbars. The door is fixedly installed on the shared locking nut via a locking handwheel. This invention uses a shared locking nut as a shared locking device to simultaneously fix the front end cover and the door, eliminating the need to re-machine the threaded fixing holes on the front end cover, making it more convenient.

[0004] However, with existing locking devices, the movable door is usually directly attached to the chamber by bolts or magnets. Gaps can easily appear at the connection between the movable door and the chamber, causing oxygen inside the chamber to leak out during use and prolonging the treatment cycle.

[0005] Therefore, a shared locking device for the hyperbaric oxygen chamber's tie rod and door closure is proposed. Utility Model Content

[0006] In view of this, the present invention provides a shared locking device for the hyperbaric oxygen chamber lever and the chamber door, in order to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial alternative.

[0029] like Figure 1-2As shown, this utility model embodiment provides a shared locking device for the hyperbaric oxygen chamber pull rod and the chamber door, including a housing 1. The front side of the housing 1 is movably connected to a movable door 2 via a pivot. A locking mechanism 3 is provided on the front side of the housing 1. The locking mechanism 3 includes a rotating rod 301, a handle 302, and a fixing block 303. The rear side of the rotating rod 301 is movably connected to the front side of the movable door 2 via a pivot. The rear side of the fixing block 303 is fixedly connected to the front side of the housing 1. The rear side of the handle 302 is fixedly connected to the front side of the rotating rod 301. The bottom of the rotating rod 301 is movably connected to the inside of the fixing block 303. An observation window 4 is provided on the front side of the movable door 2. The observation window 4 is made of transparent acrylic sheet. A curved groove 5 is provided on the front side of the movable door 2. A sliding rod 6 is fixedly connected to the rear side of the rotating rod 301. The rear side of the sliding rod 6 is movably connected to the inside of the curved groove 5. A placement plate 7 is fixedly connected inside the housing 1. A groove 8 is provided on the surface of the placement plate 7.

[0030] When the movable door 2 is closed by the closing mechanism 3, the rotating rod 301 is rotated so that the rotating rod 301 is placed inside the fixing block 303 to fix the movable door 2, preventing it from loosening during use, which could cause gaps at the connection and reduce the oxygen concentration inside the box 1.

[0031] Example 2

[0032] like Figure 3-5 As shown, in one embodiment, a cavity 9 is formed inside the fixing block 303, and a positioning mechanism 10 is provided inside the cavity 9. The positioning mechanism 10 includes a moving rod 1001, a fixing post 1002, a bent rod 1003, a positioning rod 1004, and a compression spring 1005. The right side of the moving rod 1001 extends through the cavity 9 to the right side of the fixing block 303, and the left side of the moving rod 1001 extends through the cavity 9. The bottom of the fixing post 1002 is fixedly connected to the top of the moving rod 1001, and the top of the fixing post 1002 extends through to the top of the bent rod 1003. The bent rod 1003 is connected to a rotating shaft. The curved rod 1003 is movably connected to the inside of the cavity 9. The surface of the curved rod 1003 contacts the surface of the positioning rod 1004. The rear side of the compression spring is fixedly connected to the front side of the positioning rod 1004. The front side of the compression spring is fixedly connected to the inside of the cavity 9. The rear side of the positioning rod 1004 extends into the inside of the rotating rod 301. A fixing groove 11 is provided on the surface of the rotating rod 301. The rear side of the positioning rod 1004 is movably connected to the inside of the fixing groove 11. A limiting rod 12 is fixedly connected to the left side of the positioning rod 1004. A limiting groove 13 is provided inside the cavity 9. The bottom of the limiting rod 12 is movably connected to the inside of the limiting groove 13.

[0033] When the rotating rod 301 is closed by the positioning mechanism 10, the positioning rod 1004 is accurately inserted into the interior of the rotating rod 301, which increases the stability of the rotating rod 301 and makes the rotating rod 301 stable and fixed. By setting the limiting rod 12 and the limiting groove 13, the positioning rod 1004 moves according to the movement trajectory provided by the limiting groove 13, ensuring the normal use of the overall structure.

[0034] When this utility model is in operation: pulling the moving rod 1001 to the right causes the fixed column 1002 to move to the right. The fixed column 1002 causes the bent rod 1003 to rotate around the pivot. During rotation, the surface of the bent rod 1003 presses against the surface of the positioning rod 1004, causing the positioning rod 1004 to move forward. As the positioning rod 1004 moves forward along the movement trajectory provided by the limiting groove 13, it compresses the compression spring 1005, causing the positioning rod 1004 to move into the cavity 9. At this time, the rotating rod 301 can be rotated. The rotating rod 301 rotates along the movement trajectory provided by the curved groove 5. At this time, the movable door 2 can be opened for use. After use, the rotating rod 301 is rotated again, the moving rod 1001 is released, and the positioning rod 1004 is inserted into the fixed groove 11 by the rebound force of the compression spring 1005, thus stably fixing the movable door 2 and the rotating rod 301.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
