Abstract
The invention discloses a rolling wheel supporting frame with a damping structure and for a wheelchair. The rolling wheel supporting frame comprises a rolling wheel support and a connecting column and also comprises a compression block and a damping rubber block; the rolling wheel support comprises two rolling wheel installing plates and two first connecting lugs; the compression block comprises a second connecting lug which is in rotating connection with the two first connecting lugs. According to the rolling wheel supporting frame with the damping structure and for the wheelchair, the bumping of the wheelchair is small during usage due to the damping structure, meanwhile the structure is stable, and the labor-saving driving is achieved.
Description
Technical field
The present invention relates to a kind of bracing frame, more precisely a kind of rolling wheel support frame with shock-damping structure for wheelchair.
Background technology
Shock-damping structure is not set on wheelchair of the prior art, wheelchair jolts larger in use, very uncomfortable when use, if mounting spring on the roller of wheelchair, side makes wheelchair very built on the sand, in the time promoting wheelchair, require great effort, and use the person of wheelchair comparatively weak, cannot drive for a long time this wheelchair.
Summary of the invention
The present invention solves the existing technical problem of prior art, thereby provide a kind of with shock-damping structure, wheelchair is jolted in use less, structure is also comparatively firm simultaneously, drives the comparatively rolling wheel support frame with shock-damping structure for wheelchair of labour-saving band shock-damping structure.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
A kind of rolling wheel support frame with shock-damping structure for wheelchair, described bracing frame comprises a rolling wheel support and a joint pin, described bracing frame also comprises a compact heap and a yielding rubber piece, described rolling wheel support comprises one or two roller installing plate and two the first engaging lugs, described compact heap comprises one second engaging lug, and the second described engaging lug and the first described engaging lug are rotationally connected.
As preferred embodiment of the present invention, described compact heap also comprises a pressure strip, is provided with a bolt hole on described pressure strip, and described joint pin is connected with described bolt hole, and described yielding rubber piece is connected with the downside of described pressure strip.
As preferred embodiment of the present invention, described rolling wheel support also comprises a upper plate, and described yielding rubber piece is arranged on the top of described upper plate.
As preferred embodiment of the present invention, described two roller installing plates and two described the first engaging lugs are connected with described upper plate.
Therefore the advantage of the rolling wheel support frame with shock-damping structure for wheelchair of the present invention is, with shock-damping structure, wheelchair is jolted in use less, and structure is also comparatively firm simultaneously, drives comparatively laborsaving.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

The specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention are made to more explicit defining.
The invention provides one with shock-damping structure, wheelchair is jolted in use less, structure is also comparatively firm simultaneously, drives the comparatively rolling wheel support frame with shock-damping structure for wheelchair of labour-saving band shock-damping structure.
As shown in Figure 1 and Figure 2, a kind of rolling wheel support frame with shock-damping structure for wheelchair, this bracing frame comprises a rolling wheel support 1 and a joint pin 3, this bracing frame also comprises a compact heap 2 and a yielding rubber piece 4, this rolling wheel support 1 comprises one or two roller installing plate 11 and two the first engaging lugs 12, this compact heap 2 comprises one second engaging lug 21, and this second engaging lug 21 is rotationally connected with this first engaging lug 12.
This compact heap 2 also comprises a pressure strip 22, is provided with a bolt hole 221 on this pressure strip 22, and this joint pin 3 is connected with this bolt hole 221, and this yielding rubber piece 4 is connected with the downside of this pressure strip 22.
This rolling wheel support 1 also comprises a upper plate 13, and this yielding rubber piece 4 is arranged on the top of this upper plate 13.
These two roller installing plates 11 and these two the first engaging lugs 12 are connected with this upper plate 13.
Make the elastic connection structure that is connected between this joint pin 3 and rolling wheel support 1 by this compact heap 2 and the yielding rubber pad 4 that is arranged on compact heap 2 belows, have good cushioning effect, thereby make wheelchair more comfortable.
Below only with an embodiment, mentality of designing of the present invention is described, in the situation that system allows, the present invention can expand to external more functional module simultaneously, thereby expands to greatest extent its function.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
