Abstract
The utility model relates to a turn over mechanism for automatic body turning beds, particularly a quadric crank turn over mechanism which is composed of a motor, a speed reducer, a crank, a link rod, a rocker (a bed surface) and a stationary bar (a rigid body), wherein, a shaft coupling of the motor is connected with the speed reducer; the crank is arranged on an output shaft of the speed reducer; the other end of the crank is connected with the link rod which is connected with the rocker (a bed surface). The utility model has the advantages of simple structure, light weight, low noise, low cost, stable turnover and high safety and is suitable for various automatic body turning beds, medical nursing beds, etc.
Description
This utility model relates to a kind of automatic turnover bed turning over mechanism, particularly a kind of four connecting rod turning over mechanism.It is applicable to all kinds of automatic turnover bed, medical bed for nursing care etc.
Existing automatic turnover bed turning over mechanism, the employing sector gear transmission that has, its system rigidity requires high, and part processing precision requires high, and assembly precision requires high, and weight is big, cost is high, and transmission is not steady, and noise is big; The employing hydraulic drive that has, it needs, and hydraulic pump, noise are big, leakage of oil, cost height.
The purpose of this utility model is to provide a kind of four connecting rod turning over mechanism.Its cost is low, in light weight, noise is little, and part processing precision, assembly precision are less demanding.
This utility model adopts technical solution as described below: four connecting rod turning over mechanism are made up of motor, deceleration device, crank, connecting rod, fork (bed surface), motionless bar (rigid body), the shaft coupling of motor connects deceleration device, on the output shaft of deceleration device crank is housed, the other end connective pole of crank, connecting rod links to each other with fork (bed surface).
Deceleration device is worm gear reducer or screw thread transmission.
Fork (bed surface) is located on the lathe bed, the swing of wraparound commentaries on classics center.
Motor is a reducing motor.
This utility model drives crank, connecting rod, promotion fork (bed surface) by reducing motor by worm gear reducer or screw thread transmission and spins upside down.
Advantage of the present utility model is: 1, simple in structure, in light weight, noise is little, cost is low; 2, less demanding to part processing precision, assembly precision; 3, stand up steady, safe and reliable; 4, alleviated automatic turnover bed weight, reduced manufacturing cost, be medical automatic turnover bed key technology of achieving success.
Below in conjunction with accompanying drawing this utility model is described further:
Fig. 1 is a kind of automatic turnover bed structural representation that four connecting rod turning over mechanism are housed.
Referring to Fig. 1, four connecting rod turning over mechanism are made up of reducing motor (4), worm gear reducer (1), crank (3), connecting rod (5), fork (bed surface) (7), motionless bar (rigid body) (8), reducing motor (4) and worm gear reducer (1) are located on the gripper shoe (10), gripper shoe (10) is contained on the lathe bed (6), the shaft coupling (2) of reducing motor (4) connects worm gear reducer (1), crank (3) is housed on the output shaft of worm gear reducer (1), the other end connective pole (5) of crank (3), the other end of connecting rod (5) is contained on the fork (bed surface) (7).Fork (bed surface) (7) is located on the lathe bed (6), and center (9) swing is changeed in wraparound.
Referring to Fig. 1, automatic turnover bed shown in the figure is equipped with two group of four connecting rod turning over mechanism, can a realization left side freely stands up, the right side stands up.State is stood up shown in the direction of arrow among the figure in its right side.
That this utility model also can be used for is automatic turnover bed, medical bed for nursing care, sick bed play the back of the body, the function etc. of going down on one's knees.
