Description

Technical Field

[0001] This utility model belongs to the field of medical auxiliary device technology, and in particular relates to a medical oxygen supply tank transfer device. Background Technology

[0002] Oxygen cylinders are characterized by high oxygen content, small size, portability, and ease of use, and are commonly used in the medical field. When in use, oxygen cylinders need to be transferred and moved between patient rooms. Due to their large size and heavy weight, specialized transport equipment is required.

[0003] Existing oxygen supply cylinder transfer devices have the following drawbacks: they are difficult to adapt to oxygen supply cylinders of different sizes, have poor adaptability, result in poor placement stability of the oxygen supply cylinders, are prone to free shaking, are unsafe during transfer, and affect normal use when laid flat.

[0004] Existing patent document (publication number: CN218870730U) discloses "an oxygen cylinder transfer and fixing device", which also has the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and to provide a medical oxygen supply tank transfer device with a novel structure, which can be applied to oxygen supply tanks of different sizes and specifications, has strong applicability, high stability of oxygen supply tank placement, and is safe and convenient.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A medical oxygen supply cylinder transport device includes: a supporting base plate, support rods, and a roller assembly. The support rods are disposed on the supporting base plate, and the roller assembly is disposed between two support rods. The device is characterized by: an elastic band and a backing plate between the two support rods, with the elastic band and backing plate located on the front and rear sides of the support rods respectively. The elastic band is used to secure the oxygen supply cylinder to prevent it from tipping forward, and the backing plate is used to prevent it from tipping backward. The supporting base plate has a circular groove and elastic support components, which are distributed circumferentially around the circular groove to prevent the oxygen supply cylinder from swaying freely. This transport device has a novel structure, is suitable for oxygen supply cylinders of different sizes, has strong applicability, provides high stability when placing the oxygen supply cylinder, and is safe and convenient.

[0008] Furthermore, the backrest is equipped with an elastic pad that is in close contact with the oxygen supply tank, which improves the stability of the oxygen supply tank and prevents the oxygen supply tank from swaying backward due to gaps between the backrest and the oxygen supply tank.

[0009] Furthermore, the elastic pad has trapezoidal protrusions and trapezoidal grooves, with the grooves corresponding to the protrusions. The backing plate has trapezoidal mounting slots corresponding to the protrusions. The elastic pad and the backing plate are detachable, allowing for easy installation and replacement with elastic pads of different thicknesses. Multiple elastic pads can also be installed to accommodate the gap between the backing plate and the oxygen supply tank, ensuring contact between the elastic pad and the oxygen supply tank, thus providing strong adaptability.

[0010] Furthermore, the elastic support assembly includes a U-shaped base, a torsion spring, and a limiting block. The torsion spring connects the U-shaped base and the limiting block, and the U-shaped base is mounted on the support base plate. Rotating the limiting block outwards creates space, causing the limiting block to cause the torsion spring to twist and deform. Once the oxygen supply tank is placed in the circular groove, the limiting block is then released. The torsion spring resets, causing the limiting block to rotate back, so that the top of the limiting block abuts against the surface of the oxygen supply tank. This simultaneous action from multiple directions achieves clamping, effectively limiting the free swaying of the oxygen supply tank. The elastic support assembly has a simple structure, is easy to operate, and is highly practical.

[0011] Furthermore, the top of the limiting block is evenly distributed with semi-circular protrusions, which on the one hand increases the roughness of the top of the limiting block, thereby increasing the friction when it contacts the surface of the oxygen supply tank, and on the other hand increases the contact area between the top of the limiting block and the surface of the oxygen supply tank.

[0012] Furthermore, a support rod is rotatably connected to the back of the support plate, and a traveling wheel is rotatably connected to the bottom of the support rod. A limiting component is provided between the support rod and the support plate to restrict the free rotation of the support rod relative to the support plate. The traveling wheel moves together with the roller assembly, with a large contact area with the ground, improving the overall flexibility and stability of movement, making transportation labor-saving and convenient.

[0013] Furthermore, the limiting component includes a fixing block and a hook. The hook is rotatably connected to the backing plate, and the fixing block is located on the support rod. The fixing block has a hanging hole corresponding to the hook. When the hook is hooked into the hanging hole, the free rotation of the hook is restricted, so that the hook pulls on the support rod, restricting the free rotation of the support rod. The limiting component has a simple structure, is easy to operate, and is highly practical.

[0014] Furthermore, the handrails are equipped with anti-slip sleeves, which improves anti-slip performance, makes it less likely for hands to slip, and enhances safety.

[0015] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0016] 1. Rotate the limiting block outward to create space, causing the limiting block to drive the torsion spring to twist and deform. Once the oxygen supply tank is placed in the circular groove, release the limiting block. The torsion spring will reset and drive the limiting block to rotate, causing the top of the limiting block to abut against the surface of the oxygen supply tank. This simultaneous action from multiple directions achieves clamping, effectively limiting the free movement of the lower half of the oxygen supply tank. The elastic band covers the front side of the oxygen supply tank, preventing it from tilting forward. The rear side of the oxygen supply tank rests against the backing plate, preventing it from tilting backward. This provides front and rear limiting for the upper half of the oxygen supply tank, restricting its vertical movement and preventing it from shaking freely, resulting in high stability.

[0017] 2. The elastic pad and the backing plate are detachable, allowing for easy installation and use. It is convenient to replace elastic pads of different thicknesses, and multiple elastic pads can also be installed to adapt to the gap between the backing plate and the oxygen supply tank, so that the elastic pad and the oxygen supply tank come into contact, making it highly adaptable.

[0018] 3. Rotate the support rod backward, then hook the hook into the hanging hole to restrict the free rotation of the hook. This will cause the hook to pull the support rod, restricting its free rotation and thus restricting its free rotation relative to the backing plate. The support rod will be in an inclined state. Then, using the roller as a fulcrum, rotate the whole unit backward so that the traveling wheel touches the ground. The traveling wheel and the roller move together, resulting in a large contact area with the ground, which improves the flexibility and stability of the overall movement, making transportation labor-saving and convenient.

Detailed Implementation

[0028] like Figures 1 to 7 As shown, this utility model discloses a medical oxygen supply cylinder transfer device, comprising: a supporting base plate 1, a support rod 2, and a roller assembly. The support rod 2 is symmetrically distributed on the supporting base plate 1. The roller assembly includes a mounting shaft 3 and rollers 4. The rollers 4 are rotatably connected to both ends of the mounting shaft 3. The support rod 2 is provided with an extension 5, and the mounting shaft 3 is fixed between the extensions 5. The lowest point of the rollers 4 is on the same horizontal plane as the bottom surface of the supporting base plate 1. The rollers 4, together with the supporting base plate 1, play a supporting role, which improves the stability of the transfer device when it is laid flat. It can be used normally without removing the oxygen supply cylinder.

[0029] An elastic band 6 and a backing plate 7 are provided between the two handrails 2. The elastic band 6 is distributed longitudinally and is located on the front side of the handrail 2. The backing plate 7 is located on the rear side of the handrail 2. A circular groove 8 and an elastic support assembly 9 are provided on the support base plate 1. The elastic support assembly 9 is distributed circumferentially around the circular groove 8. The elastic support assembly 9 includes a U-shaped base 10, a torsion spring 11 and a limiting block 12. The torsion spring 11 connects the U-shaped base 10 and the limiting block 12. The U-shaped base 10 is fixed on the support base plate 1. The elastic support assembly 9 has a simple structure, is easy to operate, and is highly practical.

[0030] Rotating the limiting block 12 outward creates space, causing the limiting block 12 to drive the torsion spring 11 to twist and deform, placing the bottom of the oxygen supply tank into the circular groove 8. The circular groove 8 restricts the range of motion of the bottom of the oxygen supply tank, preventing the bottom of the oxygen supply tank from sliding freely over a large area. Then, the limiting block 12 is released, and the torsion spring 11 resets, causing the limiting block 12 to rotate back, so that the top of the limiting block 12 abuts against the surface of the oxygen supply tank 13. Multiple directions act simultaneously to achieve clamping, which can effectively limit the free swaying of the lower half of the oxygen supply tank 13. The elastic band 6 covers the front side of the oxygen supply tank 13, preventing the oxygen supply tank 13 from tilting forward. The rear side of the oxygen supply tank 13 rests on the backing plate 7, preventing the oxygen supply tank 13 from tilting backward. The upper half of the oxygen supply tank 13 is limited in the front and back, and the oxygen supply tank 13 is restricted in its vertical movement, making it less prone to free swaying and ensuring high placement stability.

[0031] The top of the limiting block 12 is evenly distributed with semi-circular protrusions 14, which increases the roughness of the top of the limiting block 12, thereby increasing the friction when it contacts the surface of the oxygen supply tank 13, and also increases the contact area between the top of the limiting block 12 and the surface of the oxygen supply tank 13.

[0032] The backing plate 7 is provided with an elastic pad 15, which can be made of rubber or silicone and has good elasticity. The elastic pad 15 is in close contact with the oxygen supply tank 13, which improves the placement stability of the oxygen supply tank 13 and prevents the oxygen supply tank 13 from shaking backward due to the gap between the backing plate 7 and the oxygen supply tank 13.

[0033] The elastic pad 15 is provided with a trapezoidal protrusion 16 and a trapezoidal groove 17, the trapezoidal groove 17 corresponds to the trapezoidal protrusion 16, and the backing plate 7 is provided with a trapezoidal mounting groove 18 corresponding to the trapezoidal protrusion 16.

[0034] The elastic pad 15 is detachable from the backing plate 7, allowing for easy installation and use. This facilitates the replacement of elastic pads 15 of different thicknesses and allows for the installation of multiple elastic pads 15 to accommodate the gap between the backing plate 7 and the oxygen supply tank 13, ensuring contact between the elastic pad 15 and the oxygen supply tank 13, thus providing strong adaptability. During installation, the trapezoidal protrusion 16 is embedded into the trapezoidal mounting groove 18, positioning the elastic pad 15 on the backing plate 7. The trapezoidal protrusion 16 is in close contact with the inner wall of the trapezoidal mounting groove 18, resulting in high friction and preventing the elastic pad 15 from easily detaching, making installation simple and reliable. Alternatively, the trapezoidal protrusion 16 of one elastic pad 15 can be embedded into the trapezoidal groove 17 of another elastic pad 15, achieving positioning and docking between adjacent elastic pads 15. The trapezoidal protrusion 16 is in close contact with the inner wall of the trapezoidal groove 17, resulting in high friction and preventing easy detachment, making installation simple and reliable.

[0035] A support rod 19 is rotatably connected to the back of the backrest 7. A traveling wheel 20 is rotatably connected to the bottom end of the support rod 19. A limiting component is provided between the support rod 19 and the backrest 7. The limiting component includes a fixing block 21 and a hook 22. The tail end of the hook 22 is rotatably connected to the backrest 7. The fixing block 21 is located on the support rod 19. The fixing block 21 has a hanging hole corresponding to the hook 22. The limiting component has a simple structure, is easy to operate, and is highly practical.

[0036] Rotate the support rod 19 backward, then hook the hook 22 into the hanging hole, restricting the free rotation of the hook 22. This allows the hook 22 to pull the support rod 19, restricting its free rotation and thus restricting its free rotation relative to the backing plate 7. The support rod 19 is in an inclined state. Then, using the roller 4 as a fulcrum, rotate the whole unit backward, causing the traveling wheel 20 to touch the ground. The traveling wheel 20 moves together with the roller 4, resulting in a large contact area with the ground, which improves the flexibility and stability of the overall movement, making transportation labor-saving and convenient.

[0037] The top of the handrail 2 is equipped with an anti-slip sleeve 23. The anti-slip sleeve 23 is made of rubber, which improves the anti-slip performance, makes it less likely for the hand to slip, and improves safety.

[0038] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
