Abstract
The invention discloses a wheelchair roll wheel assembly with a shock absorption structure. The roll wheel assembly comprises a front roll wheel component and a rear roll wheel component, wherein the front roll wheel component comprises a front rotating shaft, while the rear roll wheel component comprises a rear rotating shaft; the roll wheel assembly also comprises a supporting cross beam and two first elastic pieces, wherein four sliding holes are formed in the lower part of the supporting cross beam, one ends of the first elastic pieces are rotatably connected with the front rotating shaft, and the first elastics are slidingly connected with the sliding holes. The wheelchair roll wheel assembly with the shock absorption structure has the advantage that four shock absorbing elastic pieces are provided to achieve good shock absorption effect and high load capability.
Description
Technical field
The present invention relates to a kind of roll wheel assembly, more precisely a kind of wheelchair roll wheel assembly with shock-damping structure.
Background technology
It is that wheelchair rolls shake that the roll wheel assembly of wheelchair of the prior art relies on spring, but the damping effect of spring is poor, loads less, is not suitable for using compared with overweight people.
Summary of the invention
The present invention solves the existing technical problem of prior art, thereby provides a kind of with four damping shell fragments, good damping effect, and the larger wheelchair roll wheel assembly with shock-damping structure of load.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
A kind of wheelchair roll wheel assembly with shock-damping structure, described roll wheel assembly comprises front wheel parts and rear roller parts, described front wheel parts comprise a front rotary shaft, described rear roller parts comprise a rear rotating shaft, described roll wheel assembly also comprises a supporting traverse and two the first shell fragments, the below of described supporting traverse is provided with four slide openings, and one end of the first described shell fragment and described front rotary shaft are rotationally connected, and the first described shell fragment and described slide opening are slidably connected.
As preferred embodiment of the present invention, described roll wheel assembly also comprises two the second shell fragments, and the second described shell fragment and described rear rotating shaft are rotationally connected, and the second described shell fragment and described slide opening are slidably connected.
As preferred embodiment of the present invention, the other end of the first described shell fragment is connected with described rear rotating shaft contact, and the second described shell fragment is connected with the contact of described front rotary shaft.
As preferred embodiment of the present invention, described roll wheel assembly also comprises four spacing connecting rods, the two ends of two described spacing connecting rods are rotationally connected mutually with described supporting traverse and described front rotary shaft respectively, and the two ends of two other described spacing connecting rod are rotationally connected mutually with described supporting traverse and described rear rotating shaft respectively.
Therefore the advantage of the wheelchair roll wheel assembly with shock-damping structure of the present invention is, with four damping shell fragments, and good damping effect, and load is larger.

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 four damping shell fragments, good damping effect, and the larger wheelchair roll wheel assembly with shock-damping structure of load.
As shown in Figure 1 and Figure 2, a kind of wheelchair roll wheel assembly with shock-damping structure, this roll wheel assembly comprises front wheel parts 1 and rear roller parts 2, these front wheel parts 1 comprise a front rotary shaft 11, these rear roller parts 2 comprise a rear rotating shaft 21, and this roll wheel assembly also comprises a supporting traverse 3 and two the first shell fragments 4, and the below of this supporting traverse 3 is provided with four slide openings 31, one end of this first shell fragment 4 and this front rotary shaft 11 are rotationally connected, and this first shell fragment 4 is slidably connected with this slide opening 31.
As shown in Figure 1 and Figure 2, this roll wheel assembly also comprises two the second shell fragments 5, and this second shell fragment 5 is rotationally connected with this rear rotating shaft 21, and this second shell fragment 5 is slidably connected with this slide opening 31.
As shown in Figure 4, the other end of this first shell fragment 4 is connected with these rear rotating shaft 21 contacts, and this second shell fragment 5 is connected with these front rotary shaft 11 contacts.
As shown in Figure 1, Figure 2, Figure 3 shows, this roll wheel assembly also comprises four spacing connecting rods 6, the two ends of these two spacing connecting rods 6 are rotationally connected mutually with this supporting traverse 3 and this front rotary shaft 11 respectively, and the two ends of this two other spacing connecting rod 6 are rotationally connected mutually with this supporting traverse 3 and this rear rotating shaft 21 respectively.
Utilize two the first shell fragments 4 and two the second shell fragments 5 that are only connected with one of front rotary shaft 11 or rear rotating shaft 21, can make the distance Flexible change between front wheel parts 1 and rear roller parts 2, simultaneously the height of supporting traverse 3 also can Flexible change, and damping effect is better, and load is larger simultaneously.
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.
