[0003] The scissor beam structure used in the traditional lifting scheme includes the following structural forms: In the first structural form of the scissor beam structure, the push rod device is arranged vertically upwards, so that since the push rod device is usually a two-stage hydraulic push rod , in this case, the falling height of the hospital bed is very limited, so that the hospital bed cannot be lowered to a lower position, which brings great inconvenience to some patients with limited mobility; in the scissor beam structure of the second structural form, the The apex of the push rod device is placed at the center of the scissor beam, and the other end is fixed on the bottom plate, so that the minimum height of the hospital bed can be reduced, but when the examination bed is lowered to a certain height, the thrust of the push rod device motor will increase sharply. This requires an increase in the power of the motor, which will undoubtedly increase the cost

The invention provides auxiliary equipment for magnetic resonance imaging medical diagnosis, and belongs to the technical field of magnetic resonance imaging medical instruments. The invention adoptsthe technical solution that the auxiliary equipment for magnetic resonance imaging medical diagnosis comprises a bed board, wherein backrests are respectively arranged at two ends of the bed board; anactive lifting structure is arranged at one corner of the bottom surface of the bed board, and a passive lifting piece is arranged at each of the other three corners; the passive lifting pieces are connected with the active lifting structure in a transmission manner through a closed chain. The auxiliary equipment for magnetic resonance imaging medical diagnosis has the beneficial effects that a speed reduction motor is used for driving annular gears on guide pieces; as the top and bottom surfaces of moving guide sleeves of the guide pieces are inclined arc surfaces, when the moving guide sleeves move up and down, lifting elements of lifting assemblies are driven to move up and down together with the bed boar; therefore, the passive lifting pieces and the active lifting structure synchronously drive the bed board to rise up and fall down; during magnetic resonance imaging medical detection of a patient, the auxiliary equipment is flexible to operate, and the working burden on medical staff is greatly relieved.
Description
technical field [0001] The invention relates to the technical field of nuclear magnetic resonance medical equipment, in particular to an auxiliary equipment for nuclear magnetic resonance medical diagnosis. Background technique [0002] In MRI medical diagnostic equipment, it usually consists of a magnet with a circular cavity and a table aid. The examination bed is responsible for sending the patient to the position designated by the system for scanning. Usually, the examination bed needs to have two directions of movement, that is, vertical movement and horizontal movement, in order to send the patient on the examination bed to the circular cavity magnet specified location. In the vertical motion mechanism that realizes vertical motion, the height can be raised and lowered by using the traditional scissor beam structure through angle changes. [0003] The scissor beam structure used in the traditional lifting scheme includes the following structural forms: In the first s...
