Abstract
The utility model discloses a novel leg unfolding mechanism of a rehabilitation bed wheelchair, which comprises a bottom support assembly, a leg rest assembly and a leg connecting frame, wherein the leg rest assembly and the leg connecting frame are rotationally connected through a rotating shaft pin, a leg support connecting frame is connected to a bottom side support of the leg rest assembly through a leg rest connecting pin, and the leg connecting frame is rotationally connected with the bottom support assembly through a leg connecting pin. The cooperation of each structure under shank electric putter's effect in this structure for whole leg rest structural component plays the arbitrary regulation effect of upper and lower angle, and when falling the leg, can be according to human height and the arbitrary rotation angle 0-75 of upper and lower of comfort level adjustment shank link, when lifting the leg, can adjust 0-20 after the chair lies flat, can alleviate the uncomfortable situation of human long-time lying flat shank.
Description
Technical Field
The utility model relates to the field of intelligent wheelchairs, in particular to a novel leg unfolding mechanism of a rehabilitation bed wheelchair.
Background
The wheelchair is widely applied in rehabilitation therapy, especially the use amount of the wheelchair in the old people group is more, but in the conventional wheelchair, only people can conveniently sit on the wheelchair to realize self-control movement, the leg rest structure part of the wheelchair is more to realize folding effect, the elevation lifting effect can not be realized, and the angle of adjustment can not be arbitrarily adjusted according to the height and comfort level of the human body, so the scheme provides a novel leg unfolding mechanism of the rehabilitation bed chair.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provide a novel leg unfolding mechanism of a rehabilitation bed wheelchair.
The utility model provides the following technical scheme:
the utility model provides a novel leg unfolding mechanism of a rehabilitation bed wheelchair, which comprises a bottom support assembly, a leg rest assembly and a leg connecting frame, wherein the leg rest assembly and the leg connecting frame are rotationally connected through a rotating shaft pin;
the tail end of the bottom support assembly is connected with the leg electric push rod through a push rod connecting pin, and the end of the push rod shaft of the leg electric push rod is connected with a leg support connecting frame through a support connecting pin.
As a preferable technical scheme of the utility model, the support connecting pin forms a connecting rod structure through the leg support connecting frame and the leg connecting frame.
Compared with the prior art, the utility model has the following beneficial effects:
the cooperation of each structure under shank electric putter's effect in this structure for whole leg rest structural component plays the arbitrary regulation effect of upper and lower angle, and when falling the leg, can be according to human height and the arbitrary rotation angle 0-75 of upper and lower of comfort level adjustment shank link, when lifting the leg, can adjust 0-20 after the chair lies flat, can alleviate the uncomfortable situation of human long-time lying flat shank.
Drawings
The accompanying drawings are included to provide a further understanding of the utility model and are incorporated in and constitute a part of this specification, illustrate the utility model and together with the embodiments of the utility model, serve to explain the utility model. In the drawings:
FIG. 1 is an overall block diagram of the present utility model;
FIG. 2 is a schematic view of the present utility model after adjustment of the leg rest and wheelchair levels;
FIG. 3 is a schematic view of the leg rest assembly and leg link assembly of the present utility model after the leg link assembly is raised upwardly;
in the figure: 1. a leg rest assembly; 2. a leg connection rack; 3. leg rest connecting pins; 4. leg connecting pins; 5. a bottom support assembly; 6. a push rod connecting pin; 7. a roller pin; 8. leg support connection frames; 9. supporting the connecting pin; 10. leg electric push rod.
Detailed Description
The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings, it being understood that the preferred embodiments described herein are for illustration and explanation of the present utility model only, and are not intended to limit the present utility model. Wherein like reference numerals refer to like elements throughout.
Further, if detailed description of the known art is not necessary to illustrate the features of the present utility model, it will be omitted. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the drawings, and the words "inner" and "outer" refer to directions toward or away from, respectively, the geometric center of a particular component.
Example 1
1-3, the utility model provides a novel leg unfolding mechanism of a rehabilitation bed wheelchair, which comprises a bottom support assembly 5, a leg rest assembly 1 and a leg connecting frame 2, wherein the leg rest assembly 1 and the leg connecting frame 2 are rotationally connected through a rotating shaft pin 7, a leg support connecting frame 8 is connected to a bottom side support of the leg rest assembly 1 through a leg rest connecting pin 3, and the leg connecting frame 2 is rotationally connected with the bottom support assembly 5 through a leg connecting pin 4;
the end of the bottom support assembly 5 is connected to a leg electric putter 10 via a putter connection pin 6, and the putter end of the leg electric putter 10 is connected to a leg support connection frame 8 via a support connection pin 9.
The support link pins 9 form a link structure by the leg support link 8 and the leg link 2.
Further, the working principle of the device is as follows:
in the structure, after the electric leg pushing rod 10 works, the leg supporting connecting frame 8 is driven to move under the action of the supporting connecting pin 9 so as to lift the leg connecting frame 2, as shown in fig. 2 and 3, the leg connecting frame 2 and the leg placing frame assembly 1 are parallel by controlling the pushing rod force of the electric leg pushing rod 10, so that the whole leg placing structure part and the backrest of the wheelchair keep a horizontal structure to form a bed structure, and the old can lie on the wheelchair device as shown in fig. 2;
the leg rest assembly 1 and the leg connecting frame 2 are rotationally connected through the rotating shaft pin 7, so that the angle between the leg rest assembly 1 and the leg connecting frame 2 can be conveniently adjusted, and the leg rest is convenient.
Finally, it should be noted that: the foregoing description is only a preferred embodiment of the present utility model, and the present utility model is not limited thereto, but it is to be understood that modifications and equivalents of some of the technical features described in the foregoing embodiments may be made by those skilled in the art, although the present utility model has been described in detail with reference to the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
