Description

Technical Field

[0001] The present invention relates to the technical field of medical oxygen storage tanks, and in particular to a medical oxygen storage tank. Background Technology

[0002] Medical oxygen storage tanks are a type of equipment specifically used to store and supply medical oxygen, and are widely used in hospitals, clinics, and home care. With the advancement of medical technology and the increasing demand for oxygen applications, oxygen storage tanks are becoming increasingly important in providing respiratory support, first aid, and various types of treatments. Modern medical oxygen storage tanks are usually made of high-strength alloy materials, have excellent pressure resistance and corrosion resistance, and can safely store high-pressure oxygen.

[0003] In the medical field, oxygen is one of the key drugs to support life and treat a variety of diseases. Oxygen storage tanks must not only be able to hold enough oxygen, but also have excellent sealing and safety to prevent safety hazards such as oxygen leakage or explosion.

[0004] In addition, with the popularity of home care for patients, the demand for mobile medical oxygen storage tanks is increasing. This portable device enables patients to get the necessary oxygen support at any time without affecting their quality of life.

[0005] However, most existing medical oxygen storage tanks are transported by shoveling, using the shovel-type bottom plate and rollers at the bottom, and the roller and lever principle to transport the medical oxygen storage tank. The bottom of the medical oxygen storage tank is mostly made of a metal layer plus a paint layer. The paint layer at the bottom of the medical oxygen storage tank is easily damaged by long-term transportation and wear, causing corrosion of the medical oxygen storage tank, affecting the long-term storage and use of the medical oxygen storage tank. While transmitting oxygen through the medical oxygen storage tank, due to the position of the shovel-type bottom plate and rollers at the bottom, it is difficult for the medical oxygen storage tank to maintain a stable vertical position, making it easy for the medical oxygen storage tank to shake and tilt, affecting the stable output of internal oxygen. Therefore, a medical oxygen storage tank is introduced. SUMMARY OF THE INVENTION

[0006] The purpose of the present invention is to provide a medical oxygen storage tank to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] A medical oxygen storage tank comprises a gas storage tank, the outer wall of the gas storage tank is clamped with a positioning mechanism, one side of the positioning mechanism is provided with an adjustment mechanism, the bottom of the adjustment mechanism is installed with a lifting mechanism, and one side of the adjustment mechanism is connected to a transport frame;

[0009] A valve is provided on the top of the gas storage tank, a level is provided between the valve and the gas storage tank, and a pressure gauge is installed on one side of the level;

[0010] The positioning mechanism includes a roller. A deflection motor is installed on the side of the roller. Side plates are provided at both ends of the roller. Springs are provided inside the side plates. The side plates are connected to the roller through the springs. The outer wall of the roller is in contact with the outer wall of the gas storage tank.

[0011] A strip-shaped chute is provided inside the side plate. The side plate is connected to the spring through the strip-shaped chute. One end of the roller is clamped to the side plate through the strip-shaped chute. One end of the roller abuts against the spring. There are two groups of rollers, and the two groups of rollers are symmetrically arranged on both sides of the gas storage tank. A total of four rollers are provided in the two groups. Before loading the gas storage tank, adjust the position of the roller, control the deflection motor to drive the roller to deflect synchronously, so that the outer wall of the roller is parallel to the outer wall of the gas storage tank. Then push the roller in the direction of the gas storage tank, so that the outer wall of the roller abuts against the outer wall of the gas storage tank. When the roller abuts against the gas storage tank, one end of the roller presses the spring, and the spring contracts along the strip-shaped chute on the side plate. After the gas storage tank moves between the two groups of rollers, the spring rebounds to push the roller to clamp the gas storage tank, so that the four rollers clamp and position the gas storage tank.

[0012] The adjusting mechanism includes a rotating rod. The top of the rotating rod is connected to the positioning mechanism. A rotating shaft rod is provided at the center point of the rotating rod. The rotating rod is connected to the transfer frame through the rotating shaft rod. The rotating rod and the transfer frame form a deflectable structure through the rotating shaft rod. In the adjusting mechanism, the position of the whole device is supported by the transfer frame, and then the angle of the rotating rod is deflected through the rotating shaft rod, and at the same time, the positioning mechanism provided at the top of the rotating rod is driven to perform an arc motion, so as to adjust the horizontal height of the positioning mechanism, which is convenient for the use and operation of gas storage tanks of various heights.

[0013] The lifting mechanism includes an electric slide rail. The electric slide rail is vertically arranged at the bottom end of the rotating rod. A slider is provided on one side of the electric slide rail. A footrest is installed on the side of the slider away from the electric slide rail. The surface of the footrest supports the bottom of the gas storage tank. An electric screw rod is provided inside the electric slide rail. The electric slide rail is connected to the slider through the electric screw rod. After the lifting mechanism bears the gas storage tank, rotate the electric screw rod inside the electric slide rail to drive the slider to move up and down along one side of the electric slide rail. At the same time, the slider drives the footrest on one side to move, and the footrest pushes the gas storage tank to move up and down synchronously, quickly adjusting the height of the gas storage tank to meet the oxygen supply use of patient medical treatment and improving the applicability of the device.

[0014] The tripod is connected to one side of the slider through a rotating bearing. One end of the rotating shaft rod is connected with a driving motor, and the rotating rod drives the rotating shaft rod to rotate through the driving motor for angular deflection. Start the driving motor on one side of the rotating rod to drive the rotating rod to deflect automatically. When clamping the gas storage tank, control the driving motor to deflect the rotating rod, deflect the positioning mechanism at the top of the rotating rod towards the gas storage tank, and synchronously adjust the angle of the roller in the positioning mechanism through the deflection motor, so that the roller quickly clamps the gas storage tank. Then control the driving motor to rotate the rotating rod in the reverse direction, and use the arc-shaped deflection movement of the positioning mechanism to hoist the gas storage tank. At the same time, control the deflection motor to adjust the roller angle vertically downward. After the rotating rod deflects to the vertical direction, control the electric slide rail to lift the height of the tripod, and support the bottom of the gas storage tank through the tripod to ensure the stability of the gas storage tank.

[0015] The positioning mechanism, the adjusting mechanism and the lifting mechanism constitute a clamping module. There are two clamping modules, and the two clamping modules are symmetrically arranged on both sides of the gas storage tank. The clamping module cooperates with the spirit level to adjust the level of the gas storage tank. When the gas storage tank is connected to the clamping module, judge the overall level of the gas storage tank through the spirit level. When the gas storage tank is horizontally inclined, adjust the lifting mechanism, lift and move the tripod on the lower side. The top of the gas storage tank is stabilized by the positioning mechanism. When the gas storage tank is longitudinally inclined, adjust the adjusting mechanism, and control the rotating rod to deflect around the rotating shaft rod to ensure the horizontal stability of the gas storage tank during use, and at the same time ensure the stable output of oxygen inside the gas storage tank.

[0016] Rollers are arranged at the bottom of the transfer frame body. There are four rollers, and the four rollers are symmetrically arranged in a rectangle at the bottom of the transfer frame body. The gas storage tank is transported through the rollers at the bottom of the transfer frame body. The top of the roller is connected to the transfer frame body through a universal joint. Through the arrangement of the four rollers, the stability of the gas storage tank handling is improved.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0018] The present invention quickly clamps and transports the gas storage tank through the arranged positioning mechanism, adjusting mechanism and lifting mechanism, reduces the wear of the gas storage tank during the transportation process, improves the durability of the gas storage tank, cooperates with the spirit level at the top of the gas storage tank, reduces the shaking of the gas storage tank during the transportation process, ensures the stability of the oxygen inside the gas storage tank, and at the same time ensures the stability of the oxygen output process in the gas storage tank, avoids the influence of the tank body inclination on the stable transmission of oxygen, and at the same time avoids the problem of liquid oxygen deposition at the bottom of the gas storage tank, resulting in poor oxygen release, improves the safety of the device. Support the overall position of the device through the transfer frame body, then deflect the rotating rod through the rotating shaft rod, and at the same time drive the positioning mechanism arranged at the top of the rotating rod to perform an arc-shaped movement, adjust the horizontal height of the positioning mechanism, and facilitate the use and operation of gas storage tanks of various heights.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0036] The positioning mechanism 2 includes a roller 21, a deflection motor 22 is installed on the side of the roller 21, side plates 23 are arranged at both ends of the roller 21, a spring 24 is arranged inside the side plates 23, and the side plates 23 are connected to the roller 21 through the spring 24, and the outer wall of the roller 21 is attached to the outer wall of the air storage tank 1.

[0037] A strip-shaped chute is opened inside the side plate 23, the side plate 23 is connected to the spring 24 through the strip-shaped chute, one end of the roller 21 is clamped to the side plate 23 through the strip-shaped chute, one end of the roller 21 abuts against the spring 24, two groups of rollers 21 are provided, and the two groups of rollers 21 are symmetrically arranged on both sides of the air storage tank 1, and a total of four rollers 21 are provided. Before loading the air storage tank 1, adjust the position of the roller 21, control the deflection motor 22 to drive the roller 21 to deflect synchronously, so that the outer wall of the roller 21 is parallel to the outer wall of the air storage tank 1, and then push the roller 21 towards the air storage tank 1, so that the outer wall of the roller 21 abuts against the outer wall of the air storage tank 1. While the roller 21 abuts against the air storage tank 1, one end of the roller 21 squeezes the spring 24, and the spring 24 contracts along the strip-shaped chute on the side plate 23. After the air storage tank 1 moves between the two groups of rollers 21, the spring 24 rebounds to push the roller 21 to clamp the air storage tank 1, so that the four rollers 21 clamp and position the air storage tank 1.

[0038] The adjusting mechanism 3 includes a rotating rod 31, the top of the rotating rod 31 is connected to the positioning mechanism 2, a rotating shaft rod 32 is arranged at the center point of the rotating rod 31, the rotating rod 31 is connected to the transfer frame body 5 through the rotating shaft rod 32, and the rotating rod 31 and the transfer frame body 5 form a deflectable structure through the rotating shaft rod 32. In the adjusting mechanism 3, the position of the whole device is supported by the transfer frame body 5, and then the angle of the rotating rod 31 is deflected through the rotating shaft rod 32, and at the same time, the positioning mechanism 2 arranged at the top of the rotating rod 31 is driven to perform an arc-shaped movement, so as to adjust the horizontal height of the positioning mechanism 2, which is convenient for the use and operation of air storage tanks 1 of various heights.

[0039] The lifting mechanism 4 includes an electric slide rail 41 which is vertically arranged at the bottom end of the rotating rod 31. A slider 42 is arranged on one side of the electric slide rail 41. A tripod 43 is installed on the side of the slider 42 away from the electric slide rail 41. The surface of the tripod 43 supports the bottom of the gas storage tank 1. An electric lead screw is arranged inside the electric slide rail 41. The electric slide rail 41 is connected to the slider 42 through the electric lead screw. After the lifting mechanism 4 bears the gas storage tank 1, the electric lead screw inside the electric slide rail 41 is rotated to drive the slider 42 to move up and down along one side of the electric slide rail 41. At the same time, the slider 42 drives the tripod 43 on one side to move, and the tripod 43 pushes the gas storage tank 1 to move up and down synchronously, quickly adjusting the height of the gas storage tank 1 to meet the oxygen supply use for patient medical treatment and improving the applicability of the device.

[0040] The tripod 43 is connected to one side of the slider 42 through a rotating bearing. One end of the rotating shaft rod 32 is connected with a driving motor. The rotating rod 31 drives the rotating shaft rod 32 to rotate for angular deflection through the driving motor.

[0041] In one embodiment, the driving motor on one side of the rotating rod 31 is started to drive the rotating rod 31 to deflect automatically. When clamping the gas storage tank 1, the rotating rod 31 is deflected by controlling the driving motor, and the positioning mechanism 2 at the top of the rotating rod 31 is deflected towards the direction of the gas storage tank 1. Synchronously, the angle of the roller 21 inside the positioning mechanism 2 is adjusted by the deflection motor 22, so that the roller 21 quickly clamps the gas storage tank 1. Then, the driving motor is controlled to rotate the rotating rod 31 in the reverse direction, and the gas storage tank 1 is hoisted by the arc-shaped deflection movement of the positioning mechanism 2. At the same time, the deflection motor 22 is controlled to adjust the angle of the roller 21 vertically downward. After the rotating rod 31 is deflected to the vertical direction, the height of the tripod 43 is lifted by controlling the electric slide rail 41, and the bottom of the gas storage tank 1 is supported by the tripod 43 to ensure the stability of the gas storage tank 1.

[0042] The positioning mechanism 2, the adjusting mechanism 3 and the lifting mechanism 4 constitute a clamping module. There are two clamping modules which are symmetrically arranged on both sides of the gas storage tank 1. The clamping module cooperates with the spirit level 12 to adjust the level of the gas storage tank 1.

[0043] In one embodiment, when the gas storage tank 1 is connected to the clamping module, the overall level of the gas storage tank 1 is judged by the spirit level 12. When the gas storage tank 1 is horizontally inclined, the lifting mechanism 4 is adjusted to lift and move the tripod 43 on the lower side. The top of the gas storage tank 1 is stabilized by the positioning mechanism 2. When the gas storage tank 1 is longitudinally inclined, the adjusting mechanism 3 is adjusted to control the rotating rod 31 to deflect around the rotating shaft rod 32 to ensure the horizontal stability of the gas storage tank 1 during use and at the same time ensure the stable output of oxygen inside the gas storage tank 1.

[0044] The bottom of the transfer frame body 5 is provided with rollers 51. There are four rollers 51, and the four rollers 51 are symmetrically arranged in a rectangle at the bottom of the transfer frame body 5. Through the rollers 51 at the bottom of the transfer frame body 5, the gas storage tank 1 is transferred. The top of the roller 51 is connected to the transfer frame body 5 through a universal shaft. Through the arrangement of the four rollers 51, the stability of the handling of the gas storage tank 1 is improved.

[0045] The working principle of the present invention:

[0046] Before loading the gas storage tank 1, adjust the position of the roller 21, control the deflection motor 22 to drive the roller 21 to deflect synchronously, so that the outer wall of the roller 21 is parallel to the outer wall of the gas storage tank 1. Then push the roller 21 in the direction of the gas storage tank 1, so that the outer wall of the roller 21 abuts against the outer wall of the gas storage tank 1. When the roller 21 abuts against the gas storage tank 1, one end of the roller 21 presses the spring 24, and the spring 24 contracts along the strip-shaped chute on the side plate 23. After the gas storage tank 1 moves between the two groups of rollers 21, the spring 24 rebounds to push the roller 21 to clamp the gas storage tank 1, so that the four rollers 21 clamp and position the gas storage tank 1;

[0047] In the adjusting mechanism 3, the position of the whole device is supported by the transfer frame body 5. Then, the angle of the rotating rod 31 is deflected through the rotating shaft rod 32, and at the same time, the positioning mechanism 2 arranged at the top of the rotating rod 31 is driven to perform an arc-shaped movement, and the horizontal height of the positioning mechanism 2 is adjusted, which is convenient for the use and operation of gas storage tanks 1 of various heights;

[0048] An electric screw rod is arranged inside the electric slide rail 41. The electric slide rail 41 is connected to the slider 42 through the electric screw rod. After the lifting mechanism 4 bears the gas storage tank 1, rotate the electric screw rod inside the electric slide rail 41 to drive the slider 42 to move up and down along one side of the electric slide rail 41. At the same time, the slider 42 drives the footrest 43 on one side to move, and the footrest 43 pushes the gas storage tank 1 to move up and down synchronously, quickly adjusting the height of the gas storage tank 1 to meet the oxygen supply use for patient medical treatment and improving the applicability of the device;

[0049] Start the drive motor on one side of the rotating rod 31 to drive the rotating rod 31 to deflect automatically. When clamping the gas storage tank 1, deflect the rotating rod 31 by controlling the drive motor, deflect the positioning mechanism 2 at the top of the rotating rod 31 in the direction of the gas storage tank 1, and synchronously adjust the angle of the roller 21 in the positioning mechanism 2 through the deflection motor 22, so that the roller 21 quickly clamps the gas storage tank 1. Then control the drive motor to rotate the rotating rod 31 in the reverse direction, use the arc-shaped deflection movement of the positioning mechanism 2 to hoist the gas storage tank 1, and at the same time control the deflection motor 22 to adjust the angle of the roller 21 vertically downward. After the rotating rod 31 deflects to the vertical direction, control the electric slide rail 41 to lift the height of the footrest 43, and support the bottom of the gas storage tank 1 through the footrest 43 to ensure the stability of the gas storage tank 1;

[0050] When the gas storage tank 1 is connected to the clamping module, the spirit level 12 is used to judge the overall level of the gas storage tank 1. When the gas storage tank 1 is horizontally inclined, the lifting mechanism 4 is adjusted to lift and move the lower side of the tripod 43. The top of the gas storage tank 1 is stabilized by the positioning mechanism 2. When the gas storage tank 1 is longitudinally inclined, the adjusting mechanism 3 is adjusted to control the angle deflection of the rotating rod 31 around the rotating shaft rod 32, ensuring the horizontal stability of the gas storage tank 1 during use and at the same time ensuring the stable output of oxygen inside the gas storage tank 1;
