Description

Technical Field

[0001] The utility model relates to the technical field of MR maintenance of nuclear magnetic resonance imaging, in particular to an MR maintenance machine used for magnetic resonance imaging. Background Art

[0002] Nuclear magnetic resonance imaging, also known as magnetic resonance imaging, uses the principle of nuclear magnetic resonance. The atomic nuclei commonly used by people are: 1H, 11B, 13C, 17O, 19F and 31P. It has been widely used in physics, chemistry, medicine, petrochemical industry and archaeology. During the long-term use of nuclear magnetic resonance imaging, the wheels of the nuclear magnetic resonance imaging device will be damaged and need to be replaced with new wheels. The size of the nuclear magnetic resonance imaging device is large. If the jack is placed manually, it can only support the corners, which will damage the shell of the instrument, affect the service life of the instrument, and the support effect is not good.

[0003] The patent with publication number CN209182484U discloses an MR maintenance machine for magnetic resonance imaging, comprising a base, four wheels fixedly mounted at the bottom end of the base, a screw rotatably mounted in the inner cavity of the base, a second handle fixedly connected to one end of the screw, a moving rod slidably sleeved at the other end, a jack slidably mounted at the right end of the moving rod, and a tool placement box fixedly mounted at the top end of the base. However, the operation of replacing the wheels of the maintenance machine is relatively cumbersome, the maintenance efficiency is low, and there is room for improvement. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes an MR repair machine for magnetic resonance imaging.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The invention relates to an MR maintenance machine for magnetic resonance imaging, comprising a bottom box, wherein wheels are fixedly installed at the four corners of the bottom of the bottom box, two support plates are fixedly installed on the inner wall of the bottom of the bottom box, one side of the two support plates is provided with a mounting hole, the same first rotating shaft is rotatably installed in the two mounting holes, two ends of the first rotating shaft respectively extend outside the two mounting holes and are fixedly sleeved with discs, a pin is fixedly installed on the side of the two discs away from each other, four guide rods are fixedly installed on the inner wall of the bottom of the bottom box, guide blocks are slidably sleeved on the four guide rods, a moving frame is fixedly installed between two guide blocks on the same straight line, and the pin is slidably installed in the moving frame, two rotating rods are rotatably installed on the inner walls of both sides of the bottom box, a first transmission hole and a second transmission hole are respectively opened at the two ends of the two rotating rods, a first slider and a second slider are slidably installed in the first transmission hole and the second transmission hole, and the first slider is fixedly installed on the guide block, a lifting rod is fixedly installed on one side of the four second sliders, the bottom ends of the four lifting rods extend to the bottom of the bottom box, and the same bottom plate is fixedly installed.

[0007] Preferably, a through hole is opened on one side of the bottom box, and a second rotating shaft is rotatably installed in the through hole.

[0008] Preferably, one end of the second rotating shaft extends into the bottom box and is fixedly sleeved with a first bevel gear, and the other end of the second rotating shaft extends out of the bottom box and is fixedly mounted with a hand wheel.

[0009] Preferably, a second bevel gear located between the two support plates is fixedly sleeved on the first rotating shaft, and the second bevel gear is matched with the first bevel gear.

[0010] Preferably, a locking block is movably sleeved on the second rotating shaft, and the locking block is fixedly mounted on a side of the bottom box close to the hand wheel.

[0012] In the utility model, the MR maintenance machine for magnetic resonance imaging is described. When the wheel of the nuclear magnetic resonance imaging device is damaged and needs to be replaced, the locking handle is rotated so that the bottom end of the locking handle is away from the second rotating shaft, thereby releasing the restriction on the second rotating shaft. The hand wheel is rotated to drive the second rotating shaft to rotate, thereby causing the first bevel gear fixedly sleeved on the second rotating shaft to rotate. Since the first bevel gear and the second bevel gear are meshed, the second bevel gear can be driven to rotate. Due to the connection relationship between the second bevel gear, the first rotating shaft and the disc, the disc can be driven to rotate through the first rotating shaft, and then the pin shaft fixedly installed on the disc can be driven to rotate. Due to the arrangement of the guide rod and the guide block, the movable frame can only move vertically. Since the pin shaft is slidably installed on the movable frame, as the pin shaft rotates The movable frame can be driven to move upwards, and due to the fixed connection relationship between the movable frame, the guide block and the first slider, the first slider can be driven to move upwards. Since the first slider is slidably installed in the first transmission hole, the first slider slides in the first transmission hole while moving upwards, so that the rotating rod rotates. Due to the connection relationship between the rotating rod, the second transmission hole and the second slider, the second slider can be moved downwards. Due to the fixed connection relationship between the second slider, the lifting rod and the bottom plate, the bottom plate moves downwards. When the bottom plate contacts the ground and the wheel is away from the ground, stop turning the handle and turn the locking screw so that the bottom end of the locking screw squeezes the second rotating shaft, so that the device can be fixed in the current state, and then the wheel can be replaced. The utility model has a simple structure, a reasonable design, and is easy to operate. The entire device can be lifted by the transmission structure, so that the damaged wheel can be quickly replaced, which improves the replacement efficiency and is suitable for popularization and use.
