The invention discloses an opening type synchronous belt tensioning device. The opening type synchronous belt tensioning device comprises a base, a handle, a connecting rod, a sliding block and a pressing block; two first rotating shaft mounting bases are arranged on the rear portion of the upper surface of the base, a sliding groove is formed in the middle front portion of the upper surface of the base, the sliding block is arranged in the sliding groove, two third rotating shaft mounting bases are arranged on the rear portion of the upper surface of the sliding block, a first rotating shaftis arranged between the two first rotating shaft mounting bases through a first locking nut, a connecting part of the handle is arranged on the first rotating shaft, a third rotating shaft is arrangedbetween the two third rotating shaft mounting bases through a third locking nut, the sliding block connecting end of the connecting rod is arranged on the third rotating shaft, a handle connecting end of the connecting rod is movably connected with the connecting part of the handle through cooperation of the second rotating shaft, a shaft sleeve and a second locking nut, and a pressing block is arranged on the front middle portion of the upper surface of the sliding block. The device is ingenious in size, rapid and convenient to operate, durable in tensioning effect and particularly suitablefor secondary tensioning adjusting of a synchronous belt.
Description
technical field [0001] The invention relates to the field of medical equipment and instruments, in particular to an open synchronous belt tensioning device applied to nuclear magnetic resonance or CT equipment. Background technique [0002] Nuclear magnetic resonance machines and CT machines have become a common medical equipment, and patients usually need to be sent into the equipment for irradiation by moving the bed. However, since the nuclear magnetic resonance machine and the CT machine cannot have metal objects when they are working, the moving bed is driven by a synchronous belt. The timing belt needs to be kept in a tight state to effectively provide transmission force for the moving bed. The traditional method is to use a tension wheel, but the tension wheel mechanism is relatively large, and the space for the MRI machine and CT machine is relatively limited. The two form a conflict, and the synchronous belt will have a problem of slack after a period of use, but t...
