Description

A kind of medical care bed elevating mechanism

[technical field]

This utility model belongs to medical nursing equipment technical field, particularly relates to a kind of medical care bed elevating mechanism.

[background technology]

Along with the improvement of medical treatment and nursing condition, also for coordinating medical treatment and nursing to operate better, people propose requirements at the higher level for medical care bed function. Except back, leg elevating function, go back common demands and there is the integral elevating function of bed, even it is also desirable to have the Trendelenburg position or the tilt function of head height foot low level, namely medical care bed in the five-function described in medical care bed industry. Existing five-function bed is realized the structure of lifting and tilt function and mostly adopts two columns or other complex structures to realize; Particularly existing five-function bed structure office characteristic, is difficult to make bed put relatively low when static state, and is extremely difficult to the international standard lifting travel of 400mm when nursing procedure. And existing five-function bed is high due to manufacturing cost, only use in high-grade wards such as ICU Intensive Care Therapies. The present inventor, in the development that long campaigns is medical care bed improves, is also constantly exploring the medical care bed innovation of five-function.

[summary of the invention]

The purpose of this utility model is to design a kind of medical care bed elevating mechanism, and it is relatively low that its elevating mechanism can make when static bit that bed surface height off the ground does, and facilitates patient's bunk bed and reduces pendant bed injury; And higher lifting travel can be reached when rising, partner treatment nursing also can easily realize position and simple in construction, and cost is low, it is simple to promotes.

This utility model is realized by following technical solution: a kind of medical care bed elevating mechanism, there is head board, bed board, bedstead, cabinet base, bed underframe, also there is between bedstead and bed underframe the electric pushrod that lateral symmetry is installed, support arm, lever arm, it is arranged on the chute on a underframe, travelling arm upper end is rotatably mounted on bedstead longeron by bearing pin, two ends of lever arm lower end connecting tube are provided with the movable pulley being placed in chute, support arm upper end is rotatably installed in the middle part of travelling arm by bearing pin, support arm lower end is rotatably installed on a underframe longeron by bearing pin, electric pushrod is rotatably mounted on bedstead by bearing pin, the other end is rotatably installed on the connection sheet of the connecting tube being set up between two support arms by bearing pin.

End in order to improve the convenience of structural strength and installation, travelling arm and support arm all can weld connecting tube as one sees fit, and the connecting tube mouth of pipe all can according to corresponding constructions such as the function setting movable pulley of arm, shaft-jointed holes.

Above-mentioned described support arm, lever arm can be welded by metal pipe material or sheet material and make.

Above-mentioned described chute is spill, it is also possible to by slide rail form, as long as sliding part is designed to corresponding version.

Described movable pulley can also adopt sliding shoe structure, if intensity that can be mobile and enough on chute or slide rail neatly.

According to the lifting structure described in above-mentioned technical solution, when being in static bit, electric pushrod is contracted to the shortest position, support arm is also corresponding to the angle of lever arm is in minimum state, bed surface so can be made to accomplish the height relatively low from ground, it is easy to patient's bunk bed, or makes injury considerably reduce during unexpected pendant bed; And when for patient or nursing, under both sides electric pushrod simultaneously drives, support arm is also corresponding to the angle of lever arm to be increased, bed surface is driven to rise to design height; And when starting side electric pushrod, the support arm of side and the angle of lever arm change, it is convenient to realize the Trendelenburg position or the tilt function of head height foot low level, needed for meeting treatment and nursing procedure. The elevating mechanism manufactured and designed by this programme design ingenious, simple in construction and very rationally, cost is low, be easy to popularize.

[detailed description of the invention]

Below in conjunction with accompanying drawing, the utility model is described in further detail, the structure of this device and principle for the people of this specialty it is quite clear that. Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit this utility model.

Referring to accompanying drawing 1,2, a kind of adopt medical care bed elevating mechanism of the present utility model, it is possible to realize manufacturing by procedure below:

The head of a bed and bed board: existing conventional components can be adopted.

Bedstead and bed underframe: the metal pipe material welding of 60*30*1.8mm/50*25*1.8mm equal-specification can be adopted to make, bedstead and bed underframe are at least provided with 2 corresponding longerons installing lifting structure, the two close end of longeron all processes the shaft-jointed hole installing elevating mechanism, the nearly middle part, inner side of bed underframe longeron is provided with chute, and bedstead two ends are welded with the ear installing electric pushrod and connect sheet;

Cabinet base: can making column structure, but generally all can install castor, the specification kind of castor is more on the market, considers selection according to the requirement of client and Financial cost ability to bear.

Travelling arm and support arm may be used without 60*30*1.8mm/50*25*1.8mm equal-specification metal pipe material processing and manufacturing.

Preparing travelling arm assembly: the upper and lower side of travelling arm all bores a through hole, by integrally welded after connecting tube traverse through hole, shaft-jointed hole is processed in the end of upper connecting tube, connects by bearing pin and bedstead axle; The structure that can install movable pulley is made at the two ends of lower connecting tube, and loads onto movable pulley.

Preparing supporting arm assembly: the upper through hole of two ends processing of two support arms, be respectively arranged with the two ends traverse of a transverse tube and integrally welded, shaft-jointed hole is all made in transverse tube end; A connecting tube is welded in appropriate location, left and right, two support arm nearly middle parts, and the upper ear of middle part welding of connecting tube connects sheet.

Assembling elevating mechanism: all boring a shaft-jointed hole in the middle part of travelling arm, and assembly lower slide wheel is put into chute, assembly top is arranged on bedstead by bearing pin;The two ends on the top of supporting arm assembly are installed to the shaft-jointed hole in the middle part of travelling arm by bearing pin, the two ends of the bottom of supporting arm assembly are installed on bottom framework by bearing pin; Electric pushrod is installed on bedstead by bearing pin one end, and the other end is installed to the ear of support arm and connects sheet. The elevating mechanism left and right sides between bedstead and bottom framework is symmetrical.

Debugging: shown in accompanying drawing 1,3, when two electric pushrod synchronous averaging, bedstead status level as shown in Figure 1 is down or up; And rise when an electric pushrod starts, when another motor stops, then rising the other end on one end of bed declines, and makes bed surface inclined.

When above-mentioned elevator platform manufactures, as long as reaching requirement of strength and linkage function, described material, shape also can do suitable change certainly. Provided of course that be not that substantial innovation improves, still fall within protection interest field of the present utility model.

This utility model, to seem simple structure, is but solve the technical barrier between the ultralow bed structure and the lifting travel that perplex medical bedstead industry for a long time.
