[0050] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0051] like Figure 1 - Figure 8 As shown, this application provides a wheelchair oxygen cylinder holder, which mainly includes:

[0052] Wheelchair 1, base 2 and oxygen cylinder 10, with base 2 fixedly connected to the back of wheelchair 1;

[0053] The connecting frame 3 includes a connecting plate 301 fixedly connected to the surface of the base 2, and the connecting plate 301 is used to limit the oxygen cylinder 10.

[0054] The lifting frame 4 includes a lifting frame 401, which is used to connect the auxiliary plate 301.

[0055] Multiple clamping elements 5, each clamping element 5 including a steel bar 502, the steel bar 502 having toughness, for clamping oxygen cylinder 10;

[0056] The reset assembly 6 includes a reset spring 603, which is used to reset the lifting frame 401.

[0057] The pull rope assembly 7 includes an elastic rope 703, which is used to assist the lifting frame 401 in resetting.

[0058] Support frame 8, which includes slide rail 802 for sliding the lifting frame 401;

[0059] Positioning element 9 includes a base 901 for placing oxygen cylinder 10.

[0060] like Figure 1 - Figure 3 As shown, the connecting frame 3 also includes a reinforcing strip 302 fixedly connected to one side of the connecting plate 301 and a rubber cap 303 sleeved on the end face of the connecting plate 301;

[0061] The rubber cap 303 prevents the patient's back from contacting the sharp corner of the top of the connecting plate 301, thus protecting the patient. In addition, the reinforcing strip 302 increases the toughness of the connecting plate 301, preventing it from breaking due to excessive force.

[0062] like Figure 1 - Figure 3 As shown, the lifting frame 4 also includes an electric telescopic rod fixedly connected inside the lifting frame 401, a lifting plate 402 fixedly connected to the output end of the electric telescopic rod, and a handle 403.

[0063] The surface of the lifting plate 402 is provided with a threaded groove, and the inner wall of the threaded groove is threaded with a handle 403;

[0064] The lifting plate 402 is raised inside the lifting frame 401 by an electric telescopic rod, which is convenient for accommodating oxygen cylinders 10 of different heights. In addition, a handle 403 is installed through a threaded groove, which makes it easy to push the wheelchair 1 for movement.

[0065] like Figure 1 - Figure 7 As shown, the clamping member 5 also includes a connecting post 501 fixedly connected to the surface of the steel bar 502, a rubber sheet 503 disposed on both sides of the connecting post 501, and a sponge sheet 504 disposed on the surface of the rubber sheet 503.

[0066] The steel bar 502 is tough and undergoes a predetermined deformation according to a predetermined force;

[0067] When the rubber sheet 503 and sponge sheet 504 on the surface of the steel bar 502 come into contact with the surface of the oxygen cylinder 10, the steel bar 502 deforms and covers the outer surface of the oxygen cylinder 10. At the same time, the oxygen cylinder 10 is clamped and fixed by two sets of clamping members 5 in opposite directions.

[0068] like Figure 1 - Figure 5 As shown, the reset assembly 6 also includes a fixing plate 602 fixedly connected to one side of the connecting plate 301, a shrink tube 601 fixedly connected to the inner wall of the predetermined opening of the fixing plate 602, a fixing plate 604 provided on one side of the lifting frame 401, and a plurality of bolts 605.

[0069] The surface of the lifting frame 401 is provided with multiple threaded holes. Bolt 605 passes through the connecting hole of the fixing plate 604 and is threadedly connected to the threaded hole. The reset spring 603 is installed inside the reset spring 603. The support frame 8 also includes a support plate 801 fixedly connected to the surface of the connecting plate 301, a slide groove 803 opened on the side surface of the support plate 801, multiple support bars 805 slidably connected to the inner wall of the slide groove 803, and a limiting plate 804 fixedly connected to one end of the surface of the support plate 801.

[0070] The lifting frame 401 is mounted on the surface of the slide rail 802, and the lifting frame 401 is slidably connected to the slide rail 802;

[0071] When the oxygen cylinder 10 is placed on the positioning component 9, the return spring 603 pulls the lifting frame 401 to move on the surface of the slide rail 802, thereby pulling the lifting frame 401 back.

[0072] like Figure 1 - Figure 4 As shown, the pull rope assembly 7 also includes a storage shell 701 fixedly connected to the outer surface of the connecting plate 301, a bent tube 702 fixedly connected to the inside of the storage shell 701, a connecting block 707 fixedly connected to one end of the elastic rope 703, a fixing plate 704, and multiple bolts 705 and 706.

[0073] Elastic rope 703 is installed inside storage shell 701. Bolt 3 706 passes through the reserved hole of fixing plate 3 704 and is threaded to the connecting block 707. Multiple threaded holes 2 are opened on the surface of lifting frame 401. Bolt 2 705 passes through fixing plate 3 704 and is threaded to the threaded holes 2.

[0074] By removing bolt 3 706, the connecting block 707 can be separated from the fixing plate 3 704, making it easier for the patient's family to use wheelchair 1. In addition, by removing bolt 2 705, the fixing plate 3 704 can be separated from the lifting frame 401.

[0075] like Figure 1 - Figure 8 As shown, the positioning component 9 also includes a rubber layer 902 fixedly connected to the inner wall of the base 901 and a sponge layer 903 fixedly connected to the inner wall of the rubber layer 902;

[0076] When the oxygen cylinder 10 is placed on the positioning part 9, the sponge layer 903 and the rubber layer 902 deform, causing the protrusion at the bottom of the oxygen cylinder 10 to enter the recess of the base 901, thereby protecting the bottom of the oxygen cylinder 10.

[0077] Working principle:

[0078] The patient's family or medical staff pull the lifting frame 401, causing it to move on the surface of the slide rail 802, and stretching the return spring 603 and the elastic rope 703. At the same time, the oxygen cylinder 10 is placed on the surface of the positioning part 9, so that the protruding compression sponge layer 903 and rubber layer 902 at the bottom of the oxygen cylinder 10 enter the recess of the base 901.

[0079] After the oxygen cylinder 10 is installed in place, the patient's family stops pulling the lifting frame 401. At this time, the lifting frame 401 is pulled on the surface of the slide rail 802 by the return spring 603 and the elastic rope 703, so that the lifting frame 401 is pulled back. When the rubber sheet 503 and the sponge sheet 504 on the surface of the steel bar 502 come into contact with the surface of the oxygen cylinder 10, the steel bar 502 deforms and covers the outer surface of the oxygen cylinder 10. At the same time, the oxygen cylinder 10 is clamped and fixed by two sets of clamping parts 5 in opposite directions.

[0080] After use, the patient's family members pull the lifting frame 401 again to move it on the surface of the slide rail 802, making it easier to remove the oxygen cylinder 10. After the oxygen cylinder 10 is removed, stop pulling the lifting frame 401, so that the reset spring 603 and the elastic rope 703 pull the lifting frame 401 to move on the surface of the slide rail 802, so as to achieve the purpose of resetting the lifting frame 401.

[0081] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
