A turning-over device: the main body part comprises a four-bar mechanism, a straight bar and a bent bar. Wherein the rod piece is connected with the rod piece through a revolute pair. The size ratio between the rod pieces can be adjusted according to actual conditions to obtain mechanisms with different turning speeds and different turning angle ranges. Meanwhile, the distance between the rod pieces can be adjusted to obtain mechanisms with different turning-over characteristics. When the multiple groups of mechanisms are combined together, the pressure intensity can be greatly reduced, and the comfort level of people is improved.
The material of the surface part of the bent rod member can be selected according to actual conditions, and the bent rod member can be chromium-plated stainless steel with high strength, and the surface contact area can be increased by sleeving the flat sleeve on the rod, so that the comfort and the attractiveness are improved. When different materials are used, the maximum weight that can be borne is also different. Taking 10mm diameter chromium-plated stainless steel as an example, when the four-bar rod piece and the bent rod are made of the material, a result can be obtained through stress analysis, and when the applied force is less than or equal to 300N, the stress is less than the maximum allowable stress. Thus providing a large load-bearing linkage.
The invention uses the rotation of the four connecting rods to push the connecting straight rod as the push rod to drive the bent rod to rotate, and the bent rod generates a rotation force to the back of the person so as to realize turning over. From the figure, the connecting straight rod and the bent rod rotate on circular arcs with different radiuses. The essence of the link mechanism capable of realizing turning over is that: the connecting straight rod, the third connecting rod and the dotted line part form a triangle. According to triangle knowledge, the sum of two sides is larger than the third side, and when the third connecting rod and the connecting straight rod are on the same straight line, the turning angle is the largest at the moment, and the turning maximum angle can be calculated by solving the triangle and side length proportion.
The beneficial effects of the invention are as follows: the nursing staff can assist the elderly with inconvenient actions to turn over, and can assist the elderly to stabilize the body after turning over, thereby being beneficial to the medical staff to assist the elderly to change clothes and other operations. The machine also supports the elderly with inconvenient actions to help to turn over by self or realize the lateral lying posture; the machine is also added with a massage function, so that the discomfort of the old people in long-term lying can be effectively relieved, and the back muscles can be relaxed; compared with the multifunctional nursing bed on the market at present, the machine has the advantages of stronger practicability, simpler structure, simpler and more convenient operation, lower manufacturing cost, adaptation to all bed heights, small occupied space and the like.
