Description

Technical Field

[0001] The utility model relates to the field of mobile transmission mechanisms, in particular to a novel mobile transmission mechanism. Background Art

[0002] As soon as MRI was introduced, it was widely favored for its excellent soft tissue imaging capabilities. With the increasing maturity of phase resonance coil technology, parallel imaging technology has become the preferred solution to these problems. The MRI bed needs to send people into the magnet for scanning, so a set of transmission mechanisms is needed to transfer people from the bed to the magnet. With the development of science and technology, from the early half-body scan to the whole-body scan, the MRI bed needs a longer movement range to meet the scanning needs. However, during the use of the existing transmission mechanism, most of the patients are moved by a single conveyor belt for scanning, and the transmission efficiency is low. In addition, the transmission mechanism structure is relatively fixed and single, and the transmission distance is relatively fixed, which cannot limit the transmission distance, reducing the efficiency of the transmission mechanism. Utility Model Content

[0003] In order to overcome the problem that during the use of the mobile transmission mechanism, the patient is mostly moved by a single conveyor belt for scanning, the transmission efficiency is low, and the transmission mechanism structure is relatively fixed and single, the transmission distance is relatively fixed, and the transmission distance cannot be limited, thereby reducing the use efficiency of the transmission mechanism.

[0004] The technical solution of the utility model is: a novel mobile transmission mechanism, including a driving wheel; also including a lower layer synchronous belt, a fixed frame, an operating box, a lower layer driven wheel, a lower layer belt tensioning wheel, an upper layer driven wheel, and an upper layer synchronous belt, the outer side of the driving wheel is movably connected with the lower layer synchronous belt, the bottom end of the lower layer synchronous belt is provided with a fixed frame for supporting and fixing the lower layer synchronous belt, and the rear end of the lower layer synchronous belt is provided with an operating box.

[0005] Preferably, the transmission efficiency of the transmission mechanism is improved by cooperating with the lower synchronous belt and the upper synchronous belt. Under the movement of the lower synchronous belt, the upper synchronous belt moves simultaneously at double speed. At the same time, the setting of the upper synchronous belt increases the transmission length of the transmission mechanism, so that the degree of scanning of the patient is more comprehensive when scanning is required, and the operation is simple and the stability is good.

[0006] Preferably, a lower driven wheel is provided inside the operating box, and a lower synchronous belt is movably connected to the outer side of the lower driven wheel, and lower belt tensioning wheels are provided on the upper and lower surfaces of the lower synchronous belt.

[0007] Preferably, two groups of upper driven wheels are arranged above the lower synchronous belt, and the outer sides of the upper driven wheels are movably connected with the upper synchronous belt, and the upper synchronous belt and the lower synchronous belt are against each other.

[0008] Preferably, a plurality of support rollers are equidistantly arranged at the bottom end of the upper synchronous belt, an upper movable frame is arranged at the top of the support rollers, and the upper movable frame is arranged between the upper synchronous belts. When the transmission mechanism is used, the upper synchronous belt drive block moves to the right together with the upper movable frame.

[0009] Preferably, a connecting block is provided at the upper end of the upper layer synchronous belt, and an upper layer synchronous belt fixing block is provided at the bottom end of the lower layer synchronous belt. When the transmission mechanism is used, since the upper layer synchronous belt has a fixed point on the fixed block, when the movable frame moves to the right, the upper layer synchronous belt moves to the right at double the moving speed.

[0010] Preferably, an upper synchronous belt drive block is provided at the left end of the left upper driven wheel, and the upper synchronous belt is connected to the upper synchronous belt drive block. When the transmission mechanism is used, the upper synchronous belt drive block moves to the right together with the upper movable frame.

[0011] Preferably, the distance between the upper synchronous belt and the lower synchronous belt is 2.5 meters, and the upper synchronous belt and the lower synchronous belt move relative to each other. When the transmission mechanism is used, the transmission distance is increased due to the certain distance difference between the upper synchronous belt and the lower synchronous belt, which facilitates a more comprehensive scan of the patient.

[0012] 1. The transmission efficiency of the transmission mechanism is improved by the cooperation of the lower synchronous belt and the upper synchronous belt. When the lower synchronous belt moves to the right, the upper synchronous belt driving block is driven. Driven by the upper synchronous belt driving block, the upper movable frame moves to the right. When the upper movable frame moves to the right, the upper synchronous belt moves to the right at double speed under the connection and fixation of the upper synchronous belt fixing block and the fixed point of the upper movable frame, so that the connecting block moves to the right, thereby accelerating the transmission efficiency of the transmission device;

[0013] 2. Through the setting of the upper synchronous belt, the upper synchronous belt moves at double speed under the movement of the lower synchronous belt. At the same time, the setting of the upper synchronous belt increases the transmission length of the transmission mechanism, so that the degree of scanning of the patient is more comprehensive when scanning is required, and the operation is simple and the stability is good.

The outer side of the driving wheel 1 is movably connected with the lower layer synchronous belt 2, and the bottom end of the lower layer synchronous belt 2 is provided with a fixing frame 3 for supporting and fixing the lower layer synchronous belt 2, and the rear end of the lower layer synchronous belt 2 is provided with an operating box 4; the interior of the operating box 4 is provided with a lower layer driven wheel 5, and the lower layer synchronous belt 2 is movably connected to the lower layer driven wheel 5. On the outside, the upper and lower surfaces of the lower synchronous belt 2 are both provided with a lower belt tensioning wheel 6; two sets of upper driven wheels 7 are relatively arranged above the lower synchronous belt 2, and the outer sides of the upper driven wheels 7 are movably connected with the upper synchronous belt 8, and the upper synchronous belt 8 and the lower synchronous belt 2 are abutted against each other. Through the setting of the upper synchronous belt 8, under the movement of the lower synchronous belt 2, the upper synchronous belt 8 moves simultaneously at double speed. At the same time, the setting of the upper synchronous belt 8 increases the transmission length of the transmission mechanism, so that the degree of scanning of the patient is more comprehensive when scanning is required, and the operation is simple and the stability is good.

[0021] See also Figure 3-4, a plurality of support rollers 9 are equidistantly arranged at the bottom end of the upper synchronous belt 8, an upper movable frame 10 is arranged at the top of the support roller 9, and the upper movable frame 10 is arranged between the upper synchronous belts 8; a connecting block 11 is arranged at the upper end of the upper synchronous belt 8, and an upper synchronous belt fixing block 12 is arranged at the bottom end of the lower upper synchronous belt 8; an upper synchronous belt driving block 13 is arranged at the left end of the left upper driven wheel 7, and the upper synchronous belt 8 and the upper synchronous belt driving block 13 are connected; the distance between the upper synchronous belt 8 and the lower synchronous belt 2 is 2.5 meters, and the upper synchronous belt 8 and the lower synchronous belt 2 are moved by 2.5 meters. Relative movement between them. In this embodiment, the transmission efficiency of the transmission mechanism is improved by the cooperation of the lower synchronous belt 2 and the upper synchronous belt 8. When the lower synchronous belt 2 moves to the right, the upper synchronous belt driving block 13 is driven. Driven by the upper synchronous belt driving block 13, the upper movable frame 10 moves to the right. Under the connection and fixation of the upper synchronous belt fixing block 12 and the fixed point where the upper movable frame 10 is connected, when the upper movable frame 10 moves to the right, the upper synchronous belt 8 moves to the right at double speed, thereby causing the connecting block 11 to move to the right, thereby accelerating the transmission efficiency of the transmission device.

[0022] When working, the driving wheel 1 is driven to rotate by an external power supply to provide initial torque for the transmission mechanism. Driven by the driving wheel 1, the lower synchronous belt 2 moves clockwise to the right to transmit the moving force. When the lower synchronous belt 2 moves to the right, the upper synchronous belt driving block 13 is driven. Driven by the upper synchronous belt driving block 13, the upper movable frame 10 moves to the right. Under the connection and fixation of the upper synchronous belt fixing block 12 and the fixed point where the upper movable frame 10 is connected, when the upper movable frame 10 moves to the right, the upper synchronous belt 8 moves to the right at double speed, thereby causing the connecting block 11 to move to the right, thereby accelerating the transmission efficiency of the transmission device and making its transmission distance longer.

[0023] Through the above steps, the transmission efficiency of the transmission mechanism is improved by the cooperation of the lower synchronous belt 2 and the upper synchronous belt 8. When the lower synchronous belt 2 moves to the right, the driving block of the upper synchronous belt 8 is driven. Driven by the driving block of the upper synchronous belt 8, the upper movable frame 10 moves to the right. At the same time, the setting of the upper synchronous belt 8 increases the transmission length of the transmission mechanism, so that the degree of scanning of the patient is more comprehensive when scanning is required, and the operation is simple and the stability is good.
