Description
Technical Field
The utility model relates to a nursing bed, in particular to a roller guide rail mechanism for a nursing bed.
Background
Traditional nursing bed, it is all through the bedstead of connection piece connection motor pole and nursing bed, and this kind of structure is unsmooth when the bedstead of nursing bed goes up and down, and the articulated department of connection piece, damages easily.
Disclosure of Invention
In order to solve the problems, the utility model provides a roller guide rail mechanism for a nursing bed.
The technical scheme of the utility model is as follows:
a roller guide rail mechanism for a nursing bed, which is arranged on a bed frame of the nursing bed; the driving device of the nursing bed is formed by connecting a motor with a motor rod, and a supporting frame is connected to the motor rod; the roller guide rail mechanism comprises a large roller and a guide rail, wherein the large roller is arranged on the support frame, and the guide rail is arranged on a bed frame of the nursing bed;
the large roller is propped against the guide rail at one side of the guide rail;
the motor rod rotates, the supporting frame swings up and down along with the motor rod, the supporting frame drives the large roller to move along the arc track, the bed frame of the nursing bed is supported and driven to lift, and the large roller rolls along with the guide rail.
The roller guide rail mechanism also comprises two small rollers which are also arranged on the support frame and synchronously pivot around the large rollers, and the two small rollers are positioned on a circle taking the large rollers as circle centers;
the two small rollers are propped against the guide rail at the other side of the guide rail and are opposite to the large rollers;
when the bed frame of the nursing bed is lifted, the two small rollers roll on the guide rail.
The support frame is pivoted with two side plates, the two side plates are respectively arranged at two sides of the large roller, the pivot shaft of the support frame is coaxial with the rotating shaft of the large roller, and the two small rollers are arranged on the two side plates;
and the two side plates pivot synchronously around the large roller.
The peripheral surfaces of the large roller and the small roller are respectively provided with a ring groove, and when the large roller and the small roller are propped against the guide rail, the guide rail partially stretches into the ring grooves on the guide rail.
The guide rail is a round rod, and the cross section of the annular groove is arc-shaped.
The utility model has the advantages that the design is reasonable, the structure is simple, the roller guide rail mechanism is designed, the roller guide rail mechanism is used for connecting the support frame and the bed frame of the nursing bed, and when the bed frame of the nursing bed is lifted, the large roller passively rolls along the guide rail and is smooth; however, this design has the risk of derailing (especially when the bed frame of the nursing bed descends, by the dead weight of the bed frame of the nursing bed, the contact between the rollers and the guide rail is kept), for this reason, we have further designed two small rollers, and by utilizing the mutual limitation of the two small rollers and the large rollers, the large rollers and the small rollers are kept reliably connected with the guide rail, and the derailment is prevented.
