Description

Technical Field

[0001] The utility model relates to the technical field of disassembly and assembly of medical oxygen cylinder valves, and specifically refers to an automatic loading and unloading device for medical oxygen cylinder valves. Background Technique

[0002] Medical oxygen cylinders are used to treat respiratory problems, provide life support for patients undergoing artificial respiration, help stabilize the heartbeats of acute patients, and serve as the basis for modern anesthesia techniques. They restore tissues by improving the oxygen supply to oxygen-starved tissues and are applicable to situations such as poisoning, cardiac or respiratory arrest, shock, and severe trauma. The oxygen cylinder valve is installed at the top of the medical oxygen cylinder, mainly to facilitate the control of the oxygen flow, ensure the safe use of the oxygen cylinder, and regulate the output oxygen pressure.

[0003] Most of the existing oxygen cylinder valves are installed or disassembled through threaded cooperation with the oxygen cylinder. When mass-producing oxygen cylinders, people usually need to use a wrench to ensure the stability of the threaded cooperation between the oxygen cylinder valve and the oxygen cylinder. The disassembly and assembly process is repetitive and laborious, with low efficiency. In addition, if the residual pressure in the oxygen cylinder exceeds the specified value, it is easy to explode during the disassembly of the oxygen cylinder valve, leading to safety risks.

[0025] Combined with the attached Figure 1 and Figure 2 , a medical oxygen cylinder valve automatic loading and unloading device includes a valve body, a base 1, and a bracket connected to the base 1.

[0026] Combined with the attached Figure 4 and Figure 5 , a clamping member capable of clamping and limiting the valve body is connected to the installation seat 5. The clamping member includes a driving rod 25 slidably penetrating through the installation seat 5. A pressing plate 26 is connected to the top end of the driving rod 25. A cone 27 is connected to the bottom end of the driving rod 25 in a driving cavity. An L-shaped rod 28 is circumferentially and slidably connected to the bottom end of the installation seat 5 in the driving cavity. The top end of the L-shaped rod 28 abuts against the side wall of the cone 27. A spring 29 is connected between the L-shaped rod 28 and the side wall of the driving cavity. The bottom end of the L-shaped rod 28 extends out of the installation seat 5 and is connected with a clamping plate 30 that cooperates with the valve body at the end.

[0027] Through the setting of the above structure, it is convenient to press the pressing plate 26. The pressing plate 26 drives the cone 27 downward through the driving rod 25.

[0031] By starting the first motor 6, the first motor 6 drives the screw rod 7. The screw rod 7 drives the mounting bracket 3 to move up and down along the guide rod 31 through the threaded cooperation with the mounting bracket 3, facilitating driving the bottle valve downward through the mounting seat 5 to cooperate with the oxygen cylinder for installation.

[0032] Combined with the attached Figure 2 and Figure 3, a driving component for driving the rotary installation of the mounting base 5 is connected to the mounting frame 3. The driving component includes a second motor 8 connected to the mounting frame 3. The power output end of the second motor 8 rotatably penetrates through the mounting frame 3 and is connected with a first gear 9 at the end. A driving wheel 10 is rotatably connected to the middle of the mounting frame 3. The driving wheel 10 penetrates through the screw rod 7.

The driving wheel 10 is connected with a driven wheel 12 through a synchronous belt. The driven wheel 12 is rotatably connected to the mounting frame 3. A third gear 13 is coaxially connected to the driven wheel 12. A fourth gear 14 meshing with the third gear 13 is connected to the mounting base 5.

[0033] By starting the second motor 8, the second motor 8 drives the first gear 9. The first gear 9 drives the driving wheel 10 through meshing with the second gear 11. The driving wheel 10 drives the driven wheel 12 through the synchronous belt to drive the third gear to rotate. The third gear drives the mounting base 5 to drive the bottle valve to rotate through meshing with the fourth gear, so as to threadedly cooperate with the oxygen cylinder along with the synchronous driving of the lifting component.

[0034] The specific usage method is as follows:

[0035] First, place the oxygen cylinder between the limiting plates 21, and then drive the lifting plate 16 through the telescopic cylinder 15 to drive the first hinge rod 17 to rotate around the hinge shaft 19. The first hinge rod 17 drives the second hinge rod 20 to drive the limiting plates 21 to approach each other, so as to facilitate clamping and limiting on both sides of the oxygen cylinder;

[0036] Then, press the pressing plate 26 to drive the rod 25 to drive the cone 27 downward. The cone 27 drives the L-shaped rod 28 to slide outward and then drives the clamping plate 30 to expand. At this time, the spring 29 is compressed and stores energy. Then, place the bottle valve in the middle of the clamping plate 30 and release the pressing plate 26. Under the reset action of the spring 29, the L-shaped rod 28 drives the clamping plate 30 to contract to clamp and limit the bottle valve. At this time, the bottle valve and the oxygen cylinder are coaxial, which is convenient for subsequent threaded cooperation;

[0037] Next, start the first motor 6. The first motor 6 drives the screw rod 7. The screw rod 7 drives the mounting frame 3 to move up and down along the guide rod 31 through threaded cooperation with the mounting frame 3, so as to drive the bottle valve downward through the mounting base 5 to cooperate with the oxygen cylinder for installation. At the same time, start the second motor 8 to drive the first gear 9. The first gear 9 drives the driving wheel 10 through meshing with the second gear 11. The driving wheel 10 drives the driven wheel 12 through the synchronous belt to drive the third gear to rotate. The third gear drives the mounting base 5 to drive the bottle valve to rotate through meshing with the fourth gear, so as to threadedly cooperate with the oxygen cylinder along with the synchronous driving of the lifting component;

[0038] When disassembly is required, the oxygen cylinder can be positioned first through the positioning component, and then the lifting component is used to drive the mounting bracket 3 to descend to the valve of the oxygen cylinder, and the clamping member is driven to open to facilitate the limiting of the valve; then the driving component is used to drive the mounting seat 5 to drive the valve to rotate counterclockwise, and at the same time the lifting component drives the mounting bracket 3 to rise in the reverse direction so as to disassemble the thread between the oxygen cylinder and the valve.
