CN201929182U - Antiskid crutch - Google Patents

Abstract

The utility model relates to an antiskid crutch, which structurally comprises a crutch rod, wherein the lower end of the crutch rod is connected with a support with the bottom surface being a plane through a universal joint, and a spring is sleeved at the joint of the crutch rod and the support. During the application process of the antiskid crutch, whatever angle is formed between the crutch rod and the ground, the lower surface of the support is contacted with the ground, so the point contact between the crutch and the ground is changed to the plane contact, the friction force is increased, and the antiskid effect is improved. By adopting the spring which is sleeved on the crutch rod and the support, the support can be automatically restored after the position of the support is changed in the twisting, so the inconvenience of use caused by the difficult restoration of the support because of the shrinkage of the universal joint can be overcome, and the application effect and the antiskid effect of the antiskid crutch can be guaranteed.

Description

Anti-skid crutch

Technical field

The utility model relates to the utensil that a kind of weakling of help walks about, specifically a kind of anti-skid crutch.

Background technology

Crutch is a kind of common tool that is used for auxiliary walking.Existing crutch generally all is that single pin supports, and the crutch that single pin supports is because its strong point has only one, and only some contacts with ground the lower surface of the strong point during use, thereby skids easily; When particularly on smooth road surface and flooring, using, skidding occurs just easilier, bring danger for the user of crutch.People had invented the crutch that multiway supports afterwards, though this crutch can conveniently be stood, because feet is more, floor space increases, thereby uses inconvenience to some extent, and also easily stick holding person or other people is tripped sometimes.

The utility model content

The purpose of this utility model just provides a kind of anti-skid crutch, to solve the technical problem that existing crutch in use skids easily.

The utility model is achieved in that a kind of anti-skid crutch, comprises the cane bar, connects the bearing that the bottom surface is the plane in the lower end of described cane bar by universal joint, is socketed with spring at the joint of described cane bar and described bearing.

The utility model also is socketed with anti-sliding sleeve on described bearing.

The utility model connects a bearing in cane bar lower end by universal joint, like this, in the use of crutch, no matter be in which kind of angle between the axial line of cane bar and the ground, the whole lower surface that all is bearing contacts with ground, thereby making between crutch and the ground to be contacted by original point is transformed into present face contact, like this, the frictional force on crutch and ground increases, and skidproof effect obviously strengthens.And be socketed in spring between cane bar and bearing, bearing after the twisting displacement can be adjusted return voluntarily, make the center line of bearing keep overlapping with the axial line of cane bar, overcome thus because of universal joint " wrinkle " makes bearing be difficult for the use inconvenience that return causes, guaranteed the use and the skidproof effect of this anti-skid crutch.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

As shown in Figure 1, this anti-skid crutch is on the basis of common single armed crutch, in the lower end of cane bar 1 universal joint 3 is housed; The bottom is located at the lower end of cane bar 1 for the bearing 5 of planar structure, and joins by universal joint 3 and cane bar 1, has formed the cane bar thus and has been connected with the universal of bearing.Universal joint can be selected the universal joint of various ways such as ball head universal for use.Joint at cane bar 1 and bearing 5 is socketed with spring 2, and the upper end of spring 2 is fixed on the cane bar 1, is screwed in the cylindrical upper end portion of bearing 5 the lower end snail button of spring 2, forms the universal syndeton of elasticity thus.On bearing 5, be socketed with the anti-sliding sleeve 4 of elastomeric material system, to strengthen skidproof effect.

This anti-skid crutch structure can also design use on the both arms crutch.

Claims (2)

1. an anti-skid crutch comprises cane bar (1), it is characterized in that, connects the bearing (5) that the bottom surface is the plane in the lower end of described cane bar (1) by universal joint (3), is socketed with spring (2) at the joint of described cane bar (1) and described bearing (5).

2. anti-skid crutch according to claim 1 is characterized in that, is socketed with anti-sliding sleeve (4) on described bearing (5).
