Description
Technical field
The present invention relates to a kind of electronic patient chair, particularly a kind ofly use electronic patient chair comfortable, that supportive is good.
Background technology
Along with scientific and technical raising, because electronic patient chair has the function of motorized adjustment seat, all kinds of hospitals are numerous and confused adopts electronic patient chair to replace common wooden chair.The structure of existing electronic patient chair generally is comprised of base, Motorized lift device, medicated cushion, backrest etc.And its electric lifting mechanism adopts traditional vertical lift guiding mechanism, substantially continue to use in fairlead the simple mode that lead is set, but this guided mode, selection and concentricity precision to material are had relatively high expectations, otherwise in the situation that pressure is larger, easily make the eccentric aggravation of lead, thereby cause frictional force to increase, and cause larger noise.And life-time service can cause than galling, the gap of lead and fairlead is progressively become greatly, the stability of guiding also can reduce gradually.For fear of the problems referred to above, usually adopt the method that improves machining accuracy and material wear-resistant performance, but will certainly greatly improve production cost like this.
Summary of the invention
The object of the invention is to, a kind of electronic patient chair is provided.It can guarantee gap and the concentric rate of lead and the fairlead of Motorized lift device in electronic patient chair, in the stability that improves lifting process simultaneously, reduces the required precision of component processing.
Technical scheme of the present invention: a kind of electronic patient chair, comprise base, base is provided with Motorized lift device, and the Motorized lift device top is provided with medicated cushion, and medicated cushion is hinged with backrest by rotating shaft, and electronic prone device is installed between backrest and medicated cushion; The place ahead of base is provided with the control step that connects Motorized lift device and electronic prone device; The both sides of described backrest are provided with handrail, the surface of handrail is foamed material layer (can be the foamed material layer that RPUF makes), be characterized in: the guiding mechanism of described Motorized lift device comprises the lead in fairlead and fairlead, lead top and base are fixed, be provided with a circle groove in described fairlead, be provided with lining in groove, also be provided with one deck liner between lining and lead.
In above-mentioned guiding mechanism, described fairlead comprises two axially part prerotation vanes of symmetry, on two part prerotation vanes, is equipped with connecting plate, between connecting plate, by screw, fixes, and two part prerotation vanes are held tightly and are fixed into complete circular tube shaped fairlead.
In aforesaid guiding mechanism, described liner is wear-resisting glue-line (available polytetrafluoroethylene floor).
In aforesaid guiding mechanism, described lining is axially arranged with opening, is the circular tube shaped do not sealed.Therefore whole mechanism, for the scalable state, allows all parts that certain trueness error is arranged.
The manufacture method of the fairlead of aforementioned guiding mechanism is characterized in: first process complete fairlead, then fairlead is half-and-half cut open, with two parts of cutting open formation fairlead of filling the span of a man's arms.
The manufacture method of the fairlead of aforementioned guiding mechanism, be characterized in, comprises the following steps:
A, manufacture complete circular tube shaped fairlead;
B, be symmetrically welded 2 flanges on the circular tube shaped fairlead;
C, along flange, vertically cut into the circular tube shaped fairlead open two identical part prerotation vanes, wherein 2 flanges are divided into 4 connecting plates that are evenly distributed on the part prerotation vane;
D, identical part prerotation vane is closed, with screw, through connecting plate, held tightly and be fixed into the circular tube shaped fairlead, get final product.
Screw described in the manufacture method of the fairlead of aforementioned guiding mechanism on connecting plate is for regulating the degree of holding tightly of two part prerotation vanes, thus the adjusting gap.
Compared with prior art, the present invention is by arranging lining and coordinating the structure of liner in fairlead, can make fairlead in the situation that machining accuracy is not very high high concentric rate and the little gap that can realize with lead.The fairlead method that first whole processing is cut open again in adding the present invention, can make fairlead fill the span of a man's arms after closer to circle, than two that cast respectively, fitness is better.Therefore the requirement on machining accuracy that the present invention not only can each parts, reduce production costs, and can effectively reduce noise and wearing and tearing.So patient chair of the present invention, stablize comfortablely more during lifting, noise is little, and loss is low, and production cost is also lower.The present invention can reduce production costs more than 30%, and the noise of lead lifting can be reduced to below 70 decibels.
