Detailed Implementation

[0046] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0047] A specific embodiment of this utility model, combined with Figure 1 , Figure 2 and Figure 3 As shown, a multifunctional oxygen cylinder holder is disclosed, including a mounting base 1, a locking mechanism 2, and guide posts 3. The lower end of the guide posts 3 is connected to the top of the mounting base 1. The locking mechanism 2 includes a crossbeam 21, a limiting component 22, and a locking component 23. The two ends of the crossbeam 21 are respectively connected to two guide posts 3. The locking component 23 is set close to the guide posts 3. The limiting component 22 is connected to the crossbeam 21. The locking component 23 is rotatably connected to the crossbeam 21. The limiting component 22 is used to limit the rotational freedom of the locking component 23. The locking component 23 is used to connect to a hospital bed or wheelchair frame.

[0048] Compared with the prior art, the multifunctional oxygen cylinder holder of this embodiment has a locking mechanism 2 including a crossbeam 21, a limiting component 22, and a locking component 23. The two ends of the crossbeam 21 are respectively connected to two guide posts 3, so that the locking mechanism 2 can adapt to beds (headboard or footboard) and wheelchair frames with different orientations. The limiting component 22 is connected to the crossbeam 21, and the locking component 23 is rotatably connected to the crossbeam 21. The limiting component 22 is used to limit the rotational freedom of the locking component 23. The locking component 23 is used to connect with the bed or wheelchair frame and can adapt to the horizontal or vertical connected parts (such as the bed or wheelchair frame). The locking component 23 can achieve a quick and stable connection with the bed or wheelchair frame, so that the multifunctional oxygen cylinder holder can be stably connected with the bed or wheelchair frame, which is convenient for using oxygen cylinders when moving the bed or wheelchair frame for outpatient examinations.

[0049] To facilitate the movement of the multi-functional oxygen cylinder holder, such as Figure 1 , Figure 2 and Figure 3 As shown, the multi-functional oxygen cylinder holder also includes casters 4, which are located at the bottom of the mounting base 1. Understandably, the casters 4 include fixed casters and movable casters. For example, two fixed casters are installed at the front end of the multi-functional oxygen cylinder holder in the forward direction, and two movable casters are installed at the rear end. Alternatively, movable casters (i.e., swivel wheels) can be installed at all four corners of the bottom of the mounting base 1, meaning four swivel wheels are provided at the four corners of the bottom of the mounting base 1.

[0050] Preferably, such as Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, there are two guide posts 3, which are arranged in parallel. The guide posts 3 are perpendicularly connected to the mounting base 1 and are located at the corners of the mounting base 1.

[0051] To install oxygen cylinders, such as Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, the top of the mounting base 1 has a first groove 11, which is a circular groove to accommodate the cylindrical shape of the oxygen cylinder. The multi-functional oxygen cylinder rack also includes an arc-shaped fixing plate 5, the lower end of which is connected to the top of the mounting base 1 and is positioned along the edge of the first groove 11. To fix the oxygen cylinder to the arc-shaped fixing plate 5, a first slot 51 is provided on the edge of the arc-shaped fixing plate 5, and a binding strap is used to connect to the first slot 51 to fix the oxygen cylinder to the arc-shaped fixing plate 5. To enhance the structural strength of the arc-shaped fixing plate 5, the multi-functional oxygen cylinder rack also includes a reinforcing column 6, one end of which is connected to the guide column 3, and the other end is connected to the outer side of the arc-shaped fixing plate 5.

[0052] Furthermore, to accommodate hospital beds and wheelchairs of different heights, both ends of the crossbeam 21 can slide up and down along the guide posts 3 at both ends. Considering that the crossbeam 21 needs to slide up and down along the guide posts 3, such as Figure 7 and Figure 8 As shown, the guide post 3 is provided with a guide groove 31, and the groove wall of the guide groove 31 is provided with a first limiting hole 311, which is evenly distributed along the length of the guide groove 31. The two ends of the crossbeam 21 are respectively connected to the guide grooves 31 on both sides. In order to cooperate with the first limiting holes 311 on the guide grooves 31 to achieve height adjustment of the crossbeam 21, as shown... Figure 9 As shown, the end of the crossbeam 21 is provided with a limiting protrusion 211, which cooperates with the first limiting hole 311. When the limiting protrusion 211 is located in the first limiting hole 311, it limits the up and down movement of the crossbeam 21.

[0053] In order to achieve the extension and retraction of the limiting protrusion 211, combined with Figure 9 and Figure 11 As shown, the end of the crossbeam 21 is provided with a second slot 212 and a stepped hole 213. One end of the stepped hole 213 communicates with the second slot 212, and the other end is used for the extension and retraction of the end of the limiting protrusion 211. The limiting protrusion 211 is a stepped column. One end of the limiting protrusion 211 abuts against the first spring 214, and the other end can extend out of the first limiting hole 311. The end of the limiting protrusion 211 extending out of the first limiting hole 311 has a hemispherical structure, and the first limiting hole 311 is a hemispherical hole, so that when force is applied to the crossbeam 21, the limiting protrusion 211 can cooperate with the first limiting hole 311 at different heights. Understandably, the other end of the first spring 214 is connected to the fixing plate 215. For example, the fixing plate 215 and the crossbeam 21 are fixed by hexagon socket screws, or they can be glued together.

[0054] Furthermore, in order to facilitate the retraction of the limiting protrusion 211, the first limiting hole 311 penetrates the side wall of the guide groove 31, and a hard rod such as an iron bar can be used to poke the end of the limiting protrusion 211 to make it retract.

[0055] In order to install the locking assembly 23, combined Figure 9 and Figure 10 As shown, the outer side of the crossbeam 21 is provided with a mounting hole 216 near the guide post 3, and a bearing 217 is provided in the mounting hole 216.

[0056] Combination Figure 2 , Figure 4 , Figure 9 and Figure 16As shown, the limiting component 22 includes a fixed base 221, a limiting pin 222, and a second spring 223. The fixed base 221 is connected to the crossbeam 21 and is located near the mounting hole 216. There are two fixed bases 221. The fixed base 221 has a first through hole 2211. The limiting pin 222 has a limiting ear 2221. The two ends of the limiting pin 222 are respectively located in the two first through holes 2211. The limiting ear 2221 is located between the two fixed bases 221. The second spring 223 is located between the two fixed bases 221 and is sleeved on the limiting pin 222. One end of the second spring 223 abuts against the limiting ear 2221, and the other end abuts against the fixed base 221 away from the mounting hole 216. Pulling the limiting ear 2221 compresses the second spring 223, allowing the limiting pin 222 to move backward and disengage from the locking assembly 23. When the limiting ear 2221 is released, the limiting pin 222 connects to the locking assembly 23 under the action of the second spring 223, restricting the rotation of the locking assembly 23.

[0057] Combination Figure 2 , Figure 4 and Figure 6 As shown, the locking assembly 23 includes a first clamp 231, a second clamp 232, and a connecting block 233. One end of the first clamp 231 is connected to the bearing 217 and can rotate synchronously with the bearing 217. The other end of the first clamp 231 is connected to the second clamp 232 and can be connected to the frame of a hospital bed or wheelchair. The two ends of the connecting block 233 are rotatably connected to the first clamp 231 and the second clamp 232, respectively.

[0058] Combination Figure 10 and Figure 12 As shown, the first clamp 231 includes a first connecting shaft 2311, a limiting platform 2312, and an arc-shaped locking part 2313 connected in sequence. The first connecting shaft 2311 is connected to the bearing 217. One end of the limiting platform 2312 is connected to the first connecting shaft 2311, and the other end is connected to one side of the arc-shaped locking part 2313. The limiting platform 2312 is uniformly provided with a plurality of second limiting holes 2314 around its circumference. Preferably, there are four second limiting holes 2314, and the included angle between the axes of adjacent second limiting holes 2314 is 90°. The second limiting holes 2314 are engaged with limiting pins 222. One end of the arc-shaped locking part 2313 is provided with a first connecting hole 2315, and the other end is provided with a second connecting hole 2316. The axis of the first connecting hole 2315 is perpendicular to the axis of the second connecting hole 2316, and the axis of the first connecting hole 2315 is parallel to the axis of the mounting hole 216.

[0059] like Figure 13As shown, the second clamp 232 is an arc-shaped plate that mates with the arc-shaped snap-fit ​​part 2313. One end of the second clamp 232 is provided with a third connecting hole 2321, and the other end is provided with a fourth connecting hole 2322. The third connecting hole 2321 is directly opposite to the first connecting hole 2315, and the axis of the fourth connecting hole 2322 is parallel to the axis of the second connecting hole 2316. Figure 12 , Figure 13 and Figure 14 As shown, to accommodate the connecting block 233, one end of the arc-shaped snap-fit ​​part 2313 is provided with a third slot 2317, and one end of the second clamp 232 is provided with a fourth slot 2323. Correspondingly, both ends of the connecting block 233 are provided with a second through hole 2331 and a third through hole 2332, respectively. The two ends of the connecting block 233 are respectively placed in the third slot 2317 and the fourth slot 2323, and then combined with... Figure 4 , Figure 6 , Figure 12 , Figure 13 and Figure 14 As shown, pin 234 passes through the second connecting hole 2316 and the second through hole 2331 to connect the connecting block 233 to the arc-shaped snap-fit ​​part 2313. Another pin 234 passes through the fourth connecting hole 2322 and the third through hole 2332 to connect the connecting block 233 to the second clamp 232. The connecting block 233 and pin 234 are rotatably connected.

[0060] Combination Figure 4 , Figure 6 and Figure 15 As shown, the locking assembly 23 also includes a T-shaped connecting rod 235, a handle 236, and a wing nut 237. One end of the T-shaped connecting rod 235 passes through the third connecting hole 2321 and the first connecting hole 2315 and connects to the wing nut 237. The other end is rotatably connected to the handle 236. The connection end between the handle 236 and the T-shaped connecting rod 235 has an eccentric structure. When the wing nut 237 is connected to the T-shaped connecting rod 235, rotating the handle 236 utilizes the eccentric structure to press or loosen the second clamp 232, thereby achieving the tightening or loosening of the hospital bed or wheelchair frame. It should be noted that when assembling the T-shaped connecting rod 235 and the handle 236, the horizontal bar of the T-shaped connecting rod 235 needs to be connected to the handle 236 first, and then the vertical bar of the T-shaped connecting rod 235 needs to be connected to the horizontal bar (e.g., by welding). The T-shaped connecting rod 235, handle 236 and wing nut 237 work together to enable quick connection or disassembly of the hospital bed or wheelchair frame without the need for tools, making it easy for users (such as nurses) to operate. The eccentric structure of the handle 236 can press the arc-shaped locking part 2313 and the second clamp 232 to achieve a stable connection between the locking component 23 and the hospital bed or wheelchair frame.

[0061] Considering that sometimes two or more oxygen cylinders are needed, in order to connect the multi-functional oxygen cylinder holder together, combined with... Figure 1 , Figure 2 and Figure 3 As shown, the multi-functional oxygen cylinder rack also includes support columns 7 and a snap-fit ​​mechanism 8. There are two support columns 7, parallel to the guide columns 3, located at the corners of the mounting base 1; that is, the two support columns 7 and the two guide columns 3 are respectively located at the top four corners of the mounting base 1. The snap-fit ​​mechanism 8 includes a docking component 81 and a clamping component 82. The docking component 81 is connected to the support columns 7 and guide columns 3, and the clamping component 82 is connected to another set of support columns 7 and guide columns 3. The docking component 81 can connect with the clamping component 82, allowing adjacent multi-functional oxygen cylinder racks to be connected together.

[0062] like Figure 1 , Figure 7 and Figure 8 As shown, the docking assembly 81 includes a connecting beam 811 and a docking block 812. The two ends of the connecting beam 811 are connected to the guide post 3 and the support post 7, respectively. The docking block 812 is located in the middle of the outer side of the connecting beam 811, that is, the docking block 812 faces the opposite direction of the oxygen cylinder. The rear end of the docking block 812 is connected to the connecting beam 811. The middle part of the docking block 812 has arc-shaped grooves 8121 on both sides. The front end of the arc-shaped grooves 8121 is a plane. The front end of the docking block 812 has a first inclined surface 8122.

The front end of the connecting block 812 passes through the gap between the upper pressure block 824 and the lower pressure block 825 and gets stuck in the space formed by the third groove 8243 and the fifth groove 8253. Under the action of the third spring 826, the connecting block 812 is pressed tightly. The lower end of the upper pressure block 824 and the upper end of the lower pressure block 825 press on the front end plane of the arc-shaped groove 8121.

[0067] To reduce the risk of oxygen cylinders tipping over and causing injury, combined with Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 and Figure 19As shown, the multifunctional oxygen cylinder holder also includes a stop bar 9.
