Converging mechanism used for nursing bed sewage treatment

Abstract

The invention discloses a converging mechanism used for nursing bed sewage treatment. The converging mechanism comprises an annular internal gear, a base and driving assemblies; a through hole is arranged in the center position of the base; the bottom end of the annular internal gear is rotatably connected with the edge of the outer side of the base; the base is provided with first hinge pins andsecond hinge pins, and is connected with the driving assemblies through the first hinge pins and the second hinge pins; the driving assemblies are arranged by at least three groups; each driving assembly includes a planetary gear, a transmission rod, a connecting rod and a converging rotating sheet; the bottom end of each planetary gear is rotatably connected with the corresponding first hinge pin; teeth on the outer side wall of each planetary gear are in meshed connection with teeth on the inner side wall of the annular internal gear; the top end of each planetary gear is fixedly connected with one end of the corresponding transmission rod, and the other end of each transmission rod is hinged with one end of the corresponding connecting rod; the other end of each connecting rod is hingedwith one end of the corresponding converging rotating sheet; and the middle part of each converging rotating sheet is rotatably connected with the corresponding second hinge pin.

Description

technical field [0001] The invention relates to the field of nursing care, in particular to a closing mechanism for treating dirt in nursing beds. Background technique [0002] As the aging of the population becomes more and more serious, the care of the elderly becomes more and more important. As a result, a rehabilitation nursing bed for the elderly was born, which allows the elderly to return to their homes for nursing care, so that the elderly can get more care at home. Good care is conducive to mental and physical recovery. And a key part of the nursing bed is the closing mechanism of the sewage treatment. At present, the sewage treatment closing mechanism of the nursing bed on the market is complicated in structure, and at the same time, they all use one or two pressing rods to close the garbage bag to the garbage disposal port. One side or one corner, which causes the garbage bag to be unevenly stressed, and it is easy to cause the garbage bag to rupture due to the u...

And a key part of the nursing bed is the closing mechanism of the sewage treatment. At present, the sewage treatment closing mechanism of the nursing bed on the market is complicated in structure, and at the same time, they all use one or two pressing rods to close the garbage bag to the garbage disposal port. One side or one corner, which causes the garbage bag to be unevenly stressed, and it is easy to cause the garbage bag to rupture due to the unilateral force elongation of the garbage bag, which brings greater inconvenience to people's nursing operations; The garbage bag closing mechanism of the nursing bed is improved to avoid the garbage bag rupture during the closing process, thus bringing convenience to the nursing work of the elderly
