The utility model provides a transfer device for operation, which belongs to the technical field of nursing auxiliary equipment and comprises a supporting bed board, a hydraulic lifting frame fixedly mounted at the top of the supporting bed board, an adjusting bed board arranged at the top of the hydraulic lifting frame, a moving groove formed in one side of the adjusting bed board, and a supporting shovel board slidably connected in the moving groove. An upper motor frame is arranged at the top of the other side of the adjusting bed plate, a lower motor frame is arranged at the bottom of the other side of the adjusting bed plate, an upper winding motor is arranged on one side of the top of the upper motor frame, a lower winding motor is arranged on one side of the bottom of the lower motor frame, the output ends of the upper winding motor and the lower winding motor are fixedly connected with a winding shaft, and a conveying belt is wound outside the winding shaft and the supporting shovel plate; according to the transferring device for the operation, the lower winding motor conveys the conveying belt, at the moment, after the supporting shovel plate is extended and flatly placed on a sickbed, the upper winding motor rotates the winding shaft, the lower winding motor is matched with the upper winding motor to drive the conveying belt, a patient is transferred to a new sickbed, and the moving amplitude in the transferring process is reduced.

The utility model relates to hydraulic pressure tight equipment technical field, concretely relates to high wear -resisting brick hydraulic pressure tight device, include: base, the base bottom is provided with four rectangular distribution's brake wheel, the support cylinder for high wear -resisting brick tight is set up in the base top, adjusting mechanism, including fixed connection in the base top's U type seat, the support cylinder is installed with the connecting block in U type seat one side, the support cylinder outside swing joint has the slope through the pin shaft, the utility model discloses the setting, when carrying out the tight operation, through the rotation second outer thread pipe, make it move in the second inner thread hole, thereby can adjust the tight force of tight device, and the second outer thread pipe moves amplitude little when rotating, thereby make the adjustment of tight force more accurate, and can adjust the inclination angle of support cylinder, make this hydraulic pressure tight device can carry out tight operation to different positions, and the suitability is better.

The present invention pertains to a crank rotation drive mechanism provided with left and right pedals that alternately apply external forces to a pair of left and right crank arms attached to a crankshaft, and an output unit that rotates integrally with the crankshaft. [Problem] To provide a crank rotation drive mechanism that can be used for a long period of time without requiring a large effort. The invention provides a pedal displacement type crank rotation driving mechanism (Z). The present invention is provided with: a pair of left and right crank arms CA and a crank rotation shaft CX2 fixed to a crank shaft CX1 axially supported by a frame F and the like; a pair of left and right swing arms A axially supported by a fixed swing fulcrum shaft A4 at a position away from the crank shaft CX1; and a first slider S1 axially supported by the crank rotation shaft CX2 and reciprocatingly moving in the longitudinal direction of the swing arms A. A second slider (S2) that is in contact with or not in contact with the first slider (S1) and intermittently reciprocates; and a pedal (P) that is attached to a second slider front block (S21) and that rotates a crankshaft (CX1) while drawing a substantially elliptical trajectory by swinging a swinging arm (A). The pedal-shifting-type crank rotation drive mechanism (Z) provides a rotation output to an output unit (5). (The main purpose of the invention) the invention is not only suitable for common bicycles, but also suitable for weak people or commercial tricycles, fitness equipment, labor-saving equipment, devices and the like.

The utility model discloses an old age rehabilitation armpit stick convenient to adjust, including support leg, the top of support leg is connected with L type pole through first length adjusting structure, the horizontal part end of L type pole is provided with inclined pole, the top of inclined pole is connected with armpit support pole through second length adjusting structure, the bottom of support leg is provided with foot pad, and the horizontal part of L type pole is provided with handle. The utility model discloses through the cooperation between support leg, L type pole, inclined pole and armpit support pole, has simplified the structure of existing armpit stick, makes this armpit stick more portable, more convenient to use, and than traditional armpit stick beautiful, more in line with the psychology and aesthetic appreciation of old people, and safe and reliable.
