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.
[0019] The purpose of this invention is to provide an oxygen cylinder holder for wheelchairs, which solves the problems existing in the prior art, facilitates the fixing of oxygen cylinders, and ensures the safety of patients, their families and medical staff.
[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0021] Example 1 This embodiment provides an oxygen cylinder mounting bracket for wheelchairs, such as... Figures 1-7 As shown, it includes a base support device 10 and an upper fixing device 20 (such as...). Figure 7 (The diagram shows the installation positions of the base support device 10 and the upper fixing device 20 on the wheelchair). The base support device 10 includes a fixed tray 13, a rotating base plate 12, and at least one first quick-release member 11.

The upper surface of the fixed tray 13 is used for placing an oxygen cylinder. Each first quick-release member 11 is fixedly disposed on the side of the rotating base plate 12 away from the fixed tray 13, and each first quick-release member 11 is used for detachably fixing to the rear of the wheelchair. On the horizontal bar 30 on one side of the bottom of the wheelchair; the upper fixing device 20 is used to be installed at the rear of the wheelchair, the upper fixing device 20 is on the same side as the base support device 10, and the upper fixing device 20 is located above the base support device 10; the upper fixing device 20 includes an upper fixing assembly and an upper binding assembly; the upper fixing assembly includes a connecting rod 25 and a second quick release member 21; the second quick release member 21 is provided at one end of the connecting rod 25, and the second quick release member 21 is used to detachably fix the upper rod 31 installed above the rear of the wheelchair; the upper binding assembly is provided at the end of the connecting rod 25 away from the second quick release member 21, and the upper binding assembly is used to bind to the oxygen cylinder.
[0022] The base support device 10 can be quickly and detachably fixed to the horizontal bar 30 at the bottom rear of the wheelchair via the first quick-release piece 11 on the rotating base plate 12. Its fixing tray 13 provides bottom support for the oxygen cylinder, and the structure where the lower end of the rotating base plate 12 is lower than the lower end of the fixing tray 13 enhances support stability.

The upper fixing device 20 is on the same side as and above the base support device 10. It is quickly and detachably fixed to the vertical bar 31 at the top rear of the wheelchair via the second quick-release piece 21 of the upper fixing assembly. The upper strapping assembly... The oxygen cylinder is secured from the top, achieving double-layer stability. This design eliminates the need for additional personnel to carry or place the cylinder, completely saving manpower costs and resolving operational inconveniences during transport. Simultaneously, the double-layer fixation structure, combined with the stable support design of the base device 10, effectively prevents the oxygen cylinder from tipping or shifting during transport, eliminating the safety hazard of high-pressure cylinder collisions, saving manpower, and ensuring the safety of patients, their families, and medical staff. Furthermore, the design of the first quick-release component 11 and the second quick-release component 21 (the connection structure between the second quick-release component 21 and the tubing is the same as the connection structure between the first quick-release component 11 and the tubing) allows for flexible assembly and disassembly of the fixing frame, adapting to different wheelchair models and enhancing the equipment's versatility and ease of use.
[0023] The following are the relevant settings for the base support device 10: Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 , Figure 2 and Figure 4 As shown, the fixed tray 13 has upward-facing flanges fixed around its perimeter.
[0024] Specifically, the fixed tray 13 has a semi-circular structure, and its specific size can be reasonably set according to the applicable oxygen cylinder size; the use of a semi-circular structure can make the bottom structure occupy less space and has no too many sharp corners, reducing the occurrence of bumps and knocks to the user.
[0025] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 4As shown, the first quick-release component 11 includes a first semi-circular clip 111 and a second semi-circular clip 112; the first semi-circular clip 111 is fixedly connected to the rotating base plate 12 (the rotating base plate 12 has two mounting holes, and two connecting posts are fixedly provided on the outer side wall of the first semi-circular clip 111, the connecting posts are inserted through the mounting holes one by one, and the part that passes through the mounting holes is fixedly connected by a nut; the mounting holes are located on both sides of the fixed tray 13 and do not affect the flipping of the fixed tray 13); one end of the first semi-circular clip 111 is connected to the second semi-circular clip 112.

The threaded rod 113 can be located in the U-shaped groove 115, and the end of the threaded rod 113 extends out of the U-shaped groove 115 and is threadedly connected to the tightening member 114. The tightening member 114 has an internal threaded hole that is threadedly connected to the threaded rod 113. The outer diameter of the end of the tightening member 114 connected to the threaded rod 113 is larger than the width of the U-shaped groove 115.
[0026] Specifically, the first quick-release component 11 is formed by adopting the structure of the first semi-circular clip 111 and the second semi-circular clip 112, so that it can be fixed on the corresponding rods of wheelchairs of different thicknesses; its installation and removal are simpler, more convenient and quick, and can be achieved without tools.
[0027] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 , Figure 2 and Figure 4 As shown, the base support device 10 also includes a lower binding assembly; the lower binding assembly is fixedly mounted on the rotating base plate 12; the lower binding assembly is used to bind to the lower end of the oxygen cylinder.
[0028] Specifically, a rotating shaft is fixed at each end of the fixed tray 13, and a fixing block is fixed at the corresponding position of the rotating base plate 12. The rotating shafts are respectively rotatably set in the corresponding fixing blocks. Regarding the fixed tray 13 being able to maintain its flipped state, its setting is the same as the existing conventional setting. For example, the rotating shaft and the fixing block have a certain rotational resistance so that the fixed tray 13 can be flipped to a horizontal or vertical state for use under human force. Alternatively, other existing structures that can support the fixed tray 13 to maintain its storage state when not in use can be used. These will not be elaborated on further here.
[0029] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 , Figure 2 and Figure 4 As shown, the lower binding assembly includes a first buckle 14 and a first binding strap 15; the first buckle 14 is fixedly disposed at one end of the first binding strap 15, and the first binding strap 15 is fixedly disposed on the side of the rotating base plate 12 near the fixed tray 13 by at least one fastener 16.
[0030] Specifically, the first buckle 14 and the first strap 15 form the structure of an existing buckle strap. Its structure and fastening adjustment principle are the same as those of an existing buckle strap, and will not be described in detail here. It can be understood that the lower binding component is an existing buckle strap with holes punched in it, and is fixed to the rotating base plate 12 by fasteners 16.
[0031] The following are the relevant settings for the upper fixing device 20: Specifically, the connecting rod 25 can be adjusted in position and supported by the second quick-release piece 21 according to the oxygen cylinder fixing requirements.
[0032] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the upper binding assembly includes a second buckle 27, a second binding strap 28, and a third binding strap 29; the second buckle 27 is fixedly disposed at one end of the second binding strap 28, and the other end of the second binding strap 28 is fixed to the side wall of the connecting rod 25; the third binding strap 29 is disposed opposite to the second binding strap 28, and one end of the third binding strap 29 is fixedly connected to the side wall of the connecting rod 25.
[0033] Specifically, the upper binding assembly also uses the existing buckle binding strap structure; it can be understood that the upper binding assembly is formed by cutting an existing complete buckle binding strap into two parts. The end of one part of the strap (the part with the buckle) is fixed to the side wall of the connecting rod 25, and one end of the other part of the strap is also fixed to the side wall of the connecting rod 25 and its opposite side wall. A bracket or other structure for fixing the end of the strap can be fixed on the corresponding side wall of the connecting rod 25 so that the strap can be fixed more conveniently.

The rotating block 23 is rotatably installed in the U-shaped rotating groove 221 around the second axis, which is located on a horizontal plane; when the connecting rod 25 is perpendicular to the vertical bar 31 on the wheelchair, the lower end of the limiting plate 24 can abut against the side wall of the rotating seat 22 away from the wheelchair vertical bar 31; and the connecting rod 25 can rotate around the second axis to a vertical state parallel to the wheelchair vertical bar 31.
[0035] Specifically, the connecting rod 25, the limiting plate 24, and the rotating block 23 can simultaneously rotate around the second axis relative to the rotating seat 22 until the axis of the connecting rod 25 is horizontal, or until the axis of the connecting rod 25 is vertical. When the axis of the connecting rod 25 is horizontal, the lower end of the limiting plate 24 on the side near the rotating seat 22 can abut against the side wall of the rotating seat 22 away from the wheelchair upright 31 to keep the axis of the connecting rod 25 horizontal.
[0036] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 5 and Figure 6 As shown, the rotating block 23 is provided with a limiting insertion hole, and the rotating seat 22 is provided with a through hole communicating with the U-shaped rotating groove 221. A limiting pin 222 is slidably arranged in the through hole (the limiting pin 222, the limiting insertion hole and the through hole are coaxially arranged, and their axis is parallel to the second axis). One end of the limiting pin 222 can be inserted into the limiting insertion hole so that the connecting rod 25 is kept in a vertical state parallel to the axis of the wheelchair upright rod 31.
