Description

Technical Field

[0001] This utility model relates to the field of structural design technology of medical devices and physical therapy equipment, and in particular to an oxygen cylinder transport vehicle. Background Technology

[0002] Oxygen cylinders, as clinical oxygen supply devices, are widely used in ward care, emergency transport, and rehabilitation therapy. The safety, convenience, and versatility of their transport process directly affect the efficiency of medical services and patient safety. Although oxygen cylinder transport vehicles currently on the market have achieved basic transport functions, they still have many shortcomings in practical applications and cannot meet diverse needs.

[0003] First, existing oxygen cylinder transport carts suffer from poor adaptability. Oxygen cylinders come in various sizes, typically ranging from 150mm to 300mm in diameter (corresponding to 10L to 50L capacity) and 800mm to 1500mm in height. Traditional transport carts often have fixed-size clamping mechanisms, only compatible with a single cylinder size. This necessitates medical institutions purchasing multiple carts of different sizes to accommodate various cylinders, increasing procurement costs and consuming significant storage space. Second, existing oxygen cylinder transport carts lack sufficient clamping stability. Traditional carts often use single-sided stop blocks or simple straps for fixation, making the cylinders prone to swaying during transport due to road bumps and turning inertia, even posing a risk of tilting. This swaying can lead to loose valve connections and oxygen leaks, causing safety incidents. Furthermore, the clamping components are often made of hard metal, directly contacting the cylinder surface; collisions during transport can easily scratch the cylinder, potentially affecting its structural strength over time. Finally, existing oxygen cylinder transport carts have poor maneuverability. In scenarios such as hospital corridor thresholds, ward door steps, and uneven surfaces in emergency access routes, blockages can easily occur, requiring multiple people to work together to lift the object and reducing transport efficiency.

[0004] As can be seen from the above, the existing oxygen cylinder transport vehicles have obvious defects in terms of specification adaptability, clamping stability, and mobility, making it difficult to meet the needs of modern medical scenarios for efficient, safe, and universal transport equipment.

[0021] The following description, in conjunction with the accompanying drawings and embodiments of the present invention, provides a more detailed account of an oxygen cylinder transport vehicle of the present invention.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0024] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0025] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features.

[0026] according to Figures 1-13As shown, the oxygen cylinder transfer cart includes: a support body 1, a lifting assembly 2, a clamping assembly 3, and sliding wheels 4. The lifting assembly 2, clamping assembly 3, and sliding wheels 4 are mounted on the support body 1. The sliding wheels 4 are positioned on the lower side of the support body 1, pushing the support body 1 to move. The clamping assembly 3 is fixedly connected to the lifting assembly 2. To secure the oxygen cylinder 01 to the support body 1, the clamping assembly 3 clamps the oxygen cylinder 01. To allow the fixed end of the oxygen cylinder 01 and the clamping assembly 3 to rise and fall to accommodate oxygen cylinders 01 of different sizes, the lifting assembly 2 drives the clamping assembly 3 to move. The clamping assembly 3 holds the oxygen cylinder 01, securing it to the support body 1. Simultaneously, the clamping assembly 3 can adjust the length of the clamping arm 33 to clamp oxygen cylinders 01 of different diameters, enabling stable clamping of oxygen cylinders 01 of different diameters. Because the lifting assembly 2 is fixedly connected to the clamping assembly 3, the lifting assembly 2 can drive the clamping assembly 3 to rise and fall to accommodate oxygen cylinders 01 of different heights.

[0027] To enable the lifting assembly 2 to perform its lifting function, the lifting assembly 2 includes: a lifting rod 21, a rotating shaft 22, a transmission component 23, and a fixed housing 24. The lifting rod 21, rotating shaft 22, and transmission component 23 are housed within the fixed housing 24. One end of the lifting rod 21 is fixedly connected to the support body 1. The fixing of one end of the lifting rod 21 to the support body 1 is preferably welded to ensure that the lifting rod 21 does not rotate with the transmission component 23. In this specific embodiment, the transmission component 23 is drive-connected to the lifting rod 21, ensuring that the transmission component 23 can move on the lifting rod 21 when it rotates. The rotating shaft 22 is drive-connected to the transmission component 23. Rotating the rotating shaft 22 drives the transmission component 23 to rotate, thereby causing the transmission component 23 to move on the lifting rod 21. Since the fixed housing 24 connects the transmission component 23 and the rotating shaft 22 inside, and the lifting rod 21 passes through the fixed housing 24 and is connected to the transmission component 23, when the transmission component 23 moves on the lifting rod 21, the rotating shaft 22 and the fixed housing 24 move together with the transmission component 23, achieving simultaneous lifting and lowering. Furthermore, according to... Figure 12 As shown, one end of the lifting rod 21 is fixed to the support body 1. The transmission component 23 is connected to the lifting rod 21. The transmission component 23 is also connected to the rotating shaft 22. The transmission component 23 and the rotating shaft 22 are connected together in the fixed shell 24. The lifting rod 21 passes through the fixed shell 24 and is connected to the transmission component 23.

[0028] To allow the lifting rod 21, transmission component 23, and rotating shaft 22 to be connected within the fixed housing 24, the fixed housing 24 includes: a lifting part 241, a transmission part 242, a base plate 243, a protective cover 244, and a fixing cover 245. The lifting part 241, transmission part 242, and base plate 243 are integrally formed to ensure connection strength. The lifting part 241 and transmission part 242 are internally connected, allowing the transmission component 23 within the lifting part 241 to rotate. The rotating shaft 22 is located within the transmission part 242, and the lifting part 241 and transmission part 242 are internally connected to allow the rotating shaft 22 to rotate and drive the transmission component 23. The protective cover 244 is located on the upper side of the lifting part 241 and is fixedly connected to the lifting part 241. The fixed connection between the protective cover 244 and the base plate 243 allows the fixed housing 24 to be connected to the lifting rod 21 along with the transmission component 23 and move with the transmission component 23. Two fixed covers 245 are respectively provided at both ends of the transmission part 242, and the fixed covers 245 are fixedly connected to the base plate part 243.

[0029] In this specific embodiment, the lifting rod 21 is a screw, and the transmission component 23 and the rotating shaft 22 are a worm gear structure, with the transmission component 23 being a worm gear and the rotating shaft 22 being a worm. Specifically, the transmission component 23 is disposed within the lifting part 241, and a threaded hole 231 is provided in the middle of the transmission component 23. The lifting rod 21 passes through the threaded hole 231 and is threadedly connected to the transmission component 23. The rotating shaft 22 is disposed within the transmission part 242, and the rotation of the rotating shaft 22 drives the transmission component 23 to rotate.

[0030] In this specific embodiment, because the transmission component 23 and the rotating shaft 22 are coupled by a worm gear, a gear ring is provided on the outer side of the transmission component 23, and a thread is provided on the outer side of the threaded portion 222 of the rotating shaft 22. The transmission component 23 and the rotating shaft 22 achieve the rotation of the rotating shaft 22 by engaging the thread and the gear ring. The rotating shaft 22 includes: a shaft body 221, a threaded portion 222, a limiting ring 223, and a connecting portion 224. To enable the rotating shaft 22 to be connected to the transmission component 23, the threaded portion 222 and the connecting portion 224 are integrally formed on both sides of the shaft body 221. To ensure that the rotating shaft 22 is disposed within the transmission part 242, a limiting ring 223 is integrally formed on the shaft body 221. To prevent the rotating shaft 22 from moving within the transmission part 23 and to prevent the rotating shaft 22 from separating from the transmission component 23, the diameter of the limiting ring 223 on the rotating shaft 22 is larger than that of the threaded portion 222, the connecting portion 224, and the shaft body 221. The limiting ring 223 is located on the side near the fixed cover 245.

[0031] The shaft 221 is fixedly connected to the clamping assembly 3. A threaded portion 222 is located within the transmission portion 242 and is connected to the transmission component 23. A limiting ring 223 is fixedly connected to the transmission portion 242 via a fixing cover 245. Specifically, the fixing cover 245 has a central opening with the same diameter as the connecting portion 224. The connecting portion 224 passes through the opening in the fixing cover 245, thus constraining the limiting ring 223. To facilitate rotation of the shaft 22, knobs 5 are fixedly connected to both sides of the shaft 22. The connecting portion 224 is fixedly connected to the knobs 5 for easy manual rotation.

[0032] To enable the clamping assembly 3 to perform its clamping function, the clamping assembly 3 includes: a support plate 31 for supporting the oxygen cylinder 01, a fixing member 32, and clamping arms 33 hinged to both sides of the support plate 31, which clamp the oxygen cylinder 01. In this way, the oxygen cylinder 01 can be fixedly surrounded by the clamping arms 33 and the support plate 31, and the large bearing area of ​​the support plate 31 further improves the stability of the oxygen cylinder 01 in the clamped state. To enable the clamping assembly 3 to rise and fall together with the lifting assembly 2, the fixing member 32 is fixedly connected to one side of the support plate 31, and the clamping arm 33 is rotatably connected to the other side. The fixing member 32 is fixedly connected to the shaft 221, connecting the support plate 31 to the shaft 221, so that when the lifting assembly 2 rises and falls, the support plate 31 is driven to rise and fall.

[0033] To enable the clamping arm 33 to hold oxygen cylinders 01 of different sizes, the clamping arm 33 includes: a first telescopic arm 331, a second telescopic arm 332, a hinged arm 333, and a limiting assembly 334. The two hinged arms 333 are rotatably connected to both sides of the support plate 31, and one side of the first telescopic arm 331 and the second telescopic arm 332 are respectively connected to the hinged arm 333.

[0034] A limiting component 334 is disposed within the hinge arm 333, limiting the connection between the first telescopic arm 331 and the second telescopic arm 332. The limiting component 334 allows the first telescopic arm 331 and the second telescopic arm 332 to extend and retract with their respective connected hinge arms 333, adjusting the clamping space. Correspondingly, since the hinge arm 333 is hinged to the support plate 31, the first telescopic arm 331 and the second telescopic arm 332 can rotate relative to the support plate 31, allowing the oxygen cylinder 01 to be quickly fixed and disassembled. A positioning post 04 is fixedly connected to the lower side of the first telescopic arm 331 and the second telescopic arm 332 near the bearing portion 11. The positioning post 04 connects to the mounting hole of the hospital bed, allowing the transport vehicle to move with the hospital bed. Of course, to ensure the other side of the two telescopic arms can be fixed, the other side of the first telescopic arm 331 and the second telescopic arm 332 can be detachably connected. In this specific embodiment, pins 7 pass through the ends of the first telescopic arm 331 and the second telescopic arm 332 respectively to fix them.

[0035] To enable the support plate 31 to hinge with the clamping arm 33, the support plate 31 includes a hinge portion 311, which is respectively disposed on both sides of the support plate 31. The hinge portions 311 on both sides are hinged with the hinge arm 333, ensuring that the hinge arm 333 will not interfere with rotation. The hinge portion 311 and the hinge arm 333 are hinged by a hinge member 6. The hinge member 6 passes through the hinge portion 311 and the hinge arm 333, enabling the hinge arm 333 to rotate. In this specific embodiment, the hinge member 6 is a screw, and the contact portion between the screw and the hinge portion 311 is threaded, while the contact portion with the hinge arm 333 is unthreaded, ensuring that the hinge arm 333 can rotate. To make the first telescopic arm 331 and the second telescopic arm 332 detachable, a protrusion 3311 is integrally formed on one side of the first telescopic arm 331, and a groove 3321 is formed on one side of the second telescopic arm 332, with the protrusion 3311 fitting into the groove 3321. The protrusion 3311 and the groove 3321 cooperate to ensure that when the first telescopic arm 331 is displaced or rotated, it will not interfere with the second telescopic arm 332.

[0036] The through protrusion 3311 has first connecting holes 02 at both ends, and the through groove 3321 has second connecting holes 03 on both sides. The first telescopic arm 331 and the second telescopic arm 332 are fixedly connected by pins 7 passing through the first connecting holes 02 and the second connecting holes 03 respectively, so as to realize the quick disassembly and fixation of the clamping arm 33, which facilitates the clamping and replacement of the oxygen cylinder 01.

[0037] To further secure the oxygen cylinder, the support sponge 8 is elastic. Since the oxygen cylinder 01 is cylindrical, to provide better support between the clamping arm 33 and the support plate 31 and to distribute the force more evenly, support sponges 8 are respectively provided on the support plate 31 and the clamping arm 33. The support sponges 8 are bonded to the support plate 31 and the clamping arm 33. The elasticity of the support sponge 8 fills the gaps between the oxygen cylinder 01, the clamping arm 33, and the support plate 31. Simultaneously, due to its elasticity, the support sponge 8 can extend and retract with the first telescopic arm 331 and the second telescopic arm 332, respectively, and the hinge arm 333. That is, it adapts to the clamping range of the telescopic arm through its own elasticity, thus acting on oxygen cylinders 01 of different sizes. In addition, the support sponge 8 provides cushioning for the oxygen cylinder 01 when the transport vehicle moves, preventing the oxygen cylinder 01 from shaking during movement and improving stability.

[0038] To allow all components to be connected to a single main body, the support body 1 includes: a load-bearing section 11, a protective column 12, a push handle 13, and a support column 14. The support column 14 ensures stable parking of the transfer vehicle on smooth surfaces or slightly inclined areas.

[0039] The supporting part 11 includes a supporting plate 111 and a connecting plate 112. The supporting plate 111 and the connecting plate 112 are integrally bent and formed. The supporting part 11 provides support for the bottom of the oxygen cylinder 01. The supporting plate 111 is fixedly connected to one side of the protective column 12, preferably by welding. The protective column provides support for the support plate 31 when the transport vehicle is moved, and also prevents the lifting rod 21 from contacting the support plate 31. A push handle 13 is fixedly connected to the other side of the protective column 12. The push handle 13 is fixedly connected to one side of the protective column 12 by a screw, and the push handle 13 facilitates pushing. The lifting rod 21 is located inside the protective column 12, and one end of the lifting rod 21 is fixedly connected to the supporting plate 111. The lower end face of the supporting plate 111 is fixedly connected to the support column 14. The connecting plate 112 has sliding wheels 4 on both sides. The connecting plate 112 is used to fix the rotating shaft of the sliding wheels 4. In this specific embodiment, the sliding wheels 4 are triangular wheels, which can quickly pass through stepped paths, facilitating the transportation of oxygen cylinders.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
