In view of the foregoing, have a kind of steady type crutch at present, its structure is as shown in Figure 4, and a connecting plate 2 is fixed in support bar 1 below, and this connecting plate below is provided with a plurality of legs 3, anti-slip rubber cover 31 of parcel on each leg 3.Because this kind steady type crutch bottom has a plurality of legs 3, with contact area of ground much larger than traditional crutch, and according to mechanics principle, the active force of human body falls within the regional center that each leg 3 is surrounded along support bar 1, therefore, stability is very high.Yet when reality was used, this kind steady type crutch but existed defective; For the serious unstable crowd of center of gravity, when it used crutch, the gradient of crutch was very big usually; At this moment, the leg 3 actual numbers that land of said connecting plate 2 belows have only 1 or 2, in the case; The frictional resistance on crutch and ground does not have obvious raising, and even more serious is, because the power that this moment, human body acted on crutch falls within outside leg 3 regions that land along support bar 1; This shows, this kind crutch under the situation that obviously tilts to use, its stable wretched insufficiency.
Summary of the invention
To the problems referred to above, the object of the present invention is to provide a kind of high steady crutch, the steady crutch of this height can keep high stability under various user modes.
The technical solution adopted for the present invention to solve the technical problems is: the steady crutch of this height comprises support bar, and said post upper is provided with handgrip, and the lower end is provided with a connecting plate; Said connecting plate below is fixed with 3 ~ 4 and surrounds polygonal leg, is enclosed with an anti-slip rubber cover on each leg; Realize flexibly connecting through the ball auxiliary connection between said support bar and the said connecting plate.
As preferably, on the said connecting plate, around said ball auxiliary connection, be provided with a constraint circle, to retrain the gradient of said support bar, prevent its over-tilting; Preferred as further, make the angle of said support bar and vertical direction constrain in variation between 0 ° ~ 45 °, at this moment, the height of said constraint circle is 1:1 with the ratio of the inside radius of constraint circle.
As preferably, also be provided with the flexible rubber layer of one deck above the said connecting plate, make under unexpected situation; When said ball auxiliary connection dislocates; Said support bar skids off behind the ball auxiliary connection under support force, can be absorbed in said flexible rubber layer, thereby produce enough big constraint friction; Prevent that said support bar breaks away from said connecting plate plane, leads to the accident of falling.
As preferably, the polygon that said leg surrounds is equilateral triangle or square; Said support bar falls within said equilateral triangle or square center.
Beneficial effect of the present invention is: the steady crutch of this height in use; Be that said support bar provides a supporting plane highly stably at first, through said ball auxiliary connection, said support bar can be supported on the said supporting plane with all angles then by each leg under said connecting plate and the connecting plate; Because the effect of contraction of ball auxiliary connection; Said support bar all the time can be at said supporting plane, that is skids on the said connecting plate, this shows; The steady crutch of this height can keep high stability under various user modes.
