Description

Technical Field

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

[0002] Medical oxygen storage tanks are a type of equipment specifically used to store and supply medical oxygen. They are widely used in hospitals, clinics, home care and other places. With the advancement of medical technology and the increase in 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 of the existing medical oxygen storage tanks are transported by shoveling, and the medical oxygen storage tanks are transported and used by using the shovel-type bottom plate at the bottom in conjunction with rollers and the principle of rollers and levers. The bottom of the medical oxygen storage tanks mostly adopts a structure of a metal layer and a paint layer. The paint layer at the bottom of the medical oxygen storage tank is easily damaged due to 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 the rollers at the bottom, it is difficult for the medical oxygen storage tank to maintain a stable vertical position, and the medical oxygen storage tank is prone to shaking and tilting, affecting the stable output of internal oxygen. Therefore, a medical oxygen storage tank is introduced. Summary of the invention

[0006] The object 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: A medical oxygen storage tank comprises a gas storage tank, wherein a positioning mechanism is clamped on the outer wall of the gas storage tank, an adjusting mechanism is arranged on one side of the positioning mechanism, a lifting mechanism is installed on the bottom of the adjusting mechanism, and a transport frame is connected to one side of the adjusting mechanism; A valve is provided on the top of the gas storage tank, a level gauge is provided between the valve and the gas storage tank, and a pressure gauge is installed on one side of the level gauge; The positioning mechanism includes a roller, a deflection motor is installed on the side of the roller, side plates are arranged at both ends of the roller, springs are arranged inside the side plates, the side plates are connected to the roller through the springs, and the outer wall of the roller is in contact with the outer wall of the gas tank.

[0008] The side plate is provided with a strip slide groove inside, and the side plate is connected to the spring through the strip slide groove. One end of the roller is clamped with the side plate through the strip slide groove, and one end of the roller is in conflict with the spring. The roller is provided with two groups, and the two groups of rollers are symmetrically arranged on both sides of the gas tank. There are four rollers in total in the two groups. Before loading the gas tank, the position of the roller is adjusted, and the deflection motor is controlled to drive the roller to deflect synchronously, so that the outer wall of the roller is parallel to the outer wall of the gas tank, and then the roller is pushed to move toward the direction of the gas tank, so that the outer wall of the roller is in conflict with the outer wall of the gas tank. When the roller is in conflict with the gas tank, one end of the roller squeezes the spring, and the spring contracts along the strip slide groove on the side plate. After the gas tank moves between the two groups of rollers, the spring rebounds and pushes the roller to clamp the gas tank, so that the four rollers clamp and position the gas tank.

[0009] The adjustment mechanism includes a rotating rod, the top of which is connected to the positioning mechanism, a rotating shaft is provided at the center of the rotating rod, the rotating rod is connected to the transport frame through the rotating shaft, and the rotating rod and the transport frame form a deflectable structure through the rotating shaft. In the adjustment mechanism, the rotating rod is deflected by the angle through the rotating shaft according to the position of the entire transport frame support device, and the positioning mechanism provided on the top of the rotating rod is driven to move in an arc, and the horizontal height of the positioning mechanism is adjusted, so as to facilitate the use and operation of gas storage tanks of various heights.

[0010] The lifting mechanism includes an electric slide rail, which is vertically arranged at the bottom end of the rotating rod. A slider is arranged on one side of the electric slide rail, and a tripod is installed on the side of the slider away from the electric slide rail, and the surface of the tripod supports the bottom of the gas tank. An electric screw is arranged inside the electric slide rail, and the electric slide rail is connected to the slider through the electric screw. After the lifting mechanism carries the gas tank, the electric screw inside the electric slide rail is rotated 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 tripod on one side to move, and the tripod pushes the gas tank to move up and down synchronously, so as to quickly adjust the height of the gas tank to meet the oxygen supply needs of patients and improve the applicability of the device.

[0011] The tripod is connected to one side of the slider through a rotating bearing, and one end of the rotating shaft is connected to a driving motor, and the rotating rod is driven by the driving motor to rotate the rotating shaft for angle deflection. The driving motor on one side of the rotating rod is started to drive the rotating rod to perform automatic deflection. When clamping the gas tank, the rotating rod is deflected by controlling the driving motor, and the positioning mechanism at the top of the rotating rod is deflected toward the gas tank. The angle of the roller in the positioning mechanism is adjusted synchronously by the deflection motor, so that the roller can quickly clamp the gas tank. Then the driving motor is controlled to rotate the rotating rod in the opposite direction, and the gas tank is hoisted by the arc deflection movement of the positioning mechanism. At the same time, the deflection motor is controlled to adjust the vertical downward angle of the roller. After the rotating rod is deflected to the vertical direction, the electric slide rail is controlled to lift the height of the tripod, and the bottom of the gas tank is supported by the tripod to ensure the stability of the gas tank.

[0012] The positioning mechanism, the adjusting mechanism and the lifting mechanism constitute a clamping module, and two clamping modules are provided. The two clamping modules are symmetrically arranged on both sides of the gas tank, and the clamping module cooperates with the level meter to adjust the level of the gas tank. When the gas tank is connected to the clamping module, the level meter is used to judge the overall level of the gas tank. When the gas tank is tilted laterally, the lifting mechanism is adjusted to lift and move the tripod on the lower side. The top of the gas tank is stabilized by the positioning mechanism. When the gas tank is tilted longitudinally, the adjusting mechanism is adjusted to control the rotation rod to deflect around the rotating shaft rod to ensure the horizontal stability of the gas tank during use, and at the same time ensure the stable output of oxygen inside the gas tank.

[0013] The bottom of the transfer frame is provided with four rollers, which are symmetrically arranged about the bottom rectangle of the transfer frame. The gas tank is transferred by the rollers at the bottom of the transfer frame, and the top of the roller is connected to the transfer frame through a universal shaft. The arrangement of the four rollers improves the stability of the gas tank transportation.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are: The present invention provides a positioning mechanism, an adjusting mechanism and a lifting mechanism to quickly clamp and transport the gas tank, reduce the wear of the gas tank during transportation, improve the durability of the gas tank, cooperate with the level meter on the top of the gas tank to reduce the shaking of the gas tank during transportation, ensure the stability of the oxygen inside the gas tank, and ensure the stability of the oxygen output process in the gas tank, avoid the influence of the tank body tilt on the stable transmission of oxygen, and avoid the problem of liquid oxygen being deposited at the bottom of the gas tank, causing poor oxygen release, thereby improving the safety of the device, and supporting the overall position of the device through the transfer frame, and then rotating the shaft rod to deflect the angle of the rotating rod, while driving the positioning mechanism provided on the top of the rotating rod to perform arc movement, and adjusting the horizontal height of the positioning mechanism, so as to facilitate the use and operation of gas tanks of various heights.

When the roller 21 is in contact with the gas tank 1, one end of the roller 21 squeezes the spring 24, and the spring 24 contracts along the strip groove on the side plate 23.

[0023] In one embodiment, the driving motor on one side of the rotating rod 31 is started to drive the rotating rod 31 to automatically deflect. When clamping the gas tank 1, the rotating rod 31 is deflected by controlling the driving motor, and the positioning mechanism 2 on the top of the rotating rod 31 is deflected toward the gas tank 1. The angle of the roller 21 in the positioning mechanism 2 is adjusted by the deflection motor 22 at the same time, so that the roller 21 can quickly clamp the gas tank 1.

There are two clamping modules, which are symmetrically arranged on both sides of the gas storage tank 1 . The clamping modules cooperate with the spirit level 12 to adjust the level of the gas storage tank 1 .

[0025] In one embodiment, when the gas tank 1 is connected to the clamping module, the level meter 12 is used to judge the overall horizontality of the gas tank 1. When the gas tank 1 is laterally tilted, the lifting mechanism 4 is adjusted to lift and move the tripod 43 on the lower side. The top of the gas tank 1 is stabilized by the positioning mechanism 2.

When the roller 21 is in conflict with the gas tank 1, one end of the roller 21 squeezes the spring 24, and the spring 24 contracts along the strip groove on the side plate 23. After the gas tank 1 moves between the two groups of rollers 21, the spring 24 rebounds and pushes the roller 21 to clamp the gas tank 1, so that the four rollers 21 clamp and position the gas tank 1; In the adjustment mechanism 3, the position of the entire device is supported by the transport frame 5, and then the rotating rod 31 is deflected by the rotation shaft 32, and at the same time, the positioning mechanism 2 set on the top of the rotating rod 31 is driven to move in an arc, and the horizontal height of the positioning mechanism 2 is adjusted, which is convenient for the use and operation of gas storage tanks 1 with various heights; An electric screw is arranged inside the electric slide rail 41, and the electric slide rail 41 is connected to the slider 42 through the electric screw. After the lifting mechanism 4 carries the gas storage tank 1, the electric 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.

When clamping the gas storage tank 1, the rotating rod 31 is deflected by controlling the driving motor, and the positioning mechanism 2 on the top of the rotating rod 31 is deflected toward the gas storage tank 1. The angle of the roller 21 in the positioning mechanism 2 is adjusted by the deflection motor 22 at the same time, so that the roller 21 can quickly clamp the gas storage tank 1. Then, the driving motor is controlled to rotate the rotating rod 31 in the opposite 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 vertical downward angle of the roller 21. After the rotating rod 31 is deflected to the vertical direction, the electric slide rail 41 is controlled to lift the height of the tripod 43, 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; When the gas tank 1 is connected to the clamping module, the level of the gas tank 1 as a whole is judged by the level meter 12. When the gas tank 1 is tilted laterally, the lifting mechanism 4 is adjusted to lift and move the tripod 43 on the lower side. The top of the gas tank 1 is stabilized by the positioning mechanism 2. When the gas tank 1 is tilted longitudinally, the adjustment mechanism 3 is adjusted to control the rotating rod 31 to deflect around the rotating shaft 32 to ensure the horizontal stability of the gas tank 1 during use, and at the same time ensure the stable output of oxygen inside the gas tank 1.
