Abstract

The invention relates to an anti-slipping underarm walking stick. Three to five steel needles are coaxially and uniformly distributed at the outer edge of the lower end face of a stick rod of the walking stick and are mounted at intervals in the radial direction; a mini-type spring is mounted in the stick rod in each steel needle; a rubber sleeve sleeves the lower part of the stick rod outside the steel needles; the rubber sleeve is provided with through holes in a manner of corresponding to the steel needles, so that compression is realized when the rubber sleeve is stressed; the springs are exposed out and the steel needles are exposed out of the lower bottom of the stick rod, so that the walking stick is prevented from slipping; meanwhile, the elastic steel needles are retracted axially so that the walking stick is in flexible contact with the ground, the slipping is buffered and the walking stick is prevented from slipping off. The whole walking stick is simple in structure, ingenious in concept, easy to manufacture and reliable to use and is an updated product of an existing walking stick; the walking stick has a wide application prospect in the market and is an ideal walking stick product for disabled people and patients.

Description

A kind of Antislip underarm crutch

Technical field

The invention belongs to crutch field, relate to anti-skid crutch, especially a kind of Antislip underarm crutch.

Background technology

The instrument that crutch is people with disability or leg patient commonly uses.Existing crutch uses oxter supporting way mostly, under support bar Bottom uses rubber to make.When crutch uses, be afraid of most is that crutch skids and causes patient to fall down and produce secondary injury.To this end, People have invented large quantities of anti-skid crutch, with the technical problem overcoming existing crutch to exist.By retrieval, find and Shen of the present invention The patent document that please be correlated with mainly has following two:

1, Antislip underarm crutch (CN103315883A).Disclose Antislip underarm crutch, including supporting part, the first support bar, Second support bar, the 3rd support bar, connecting rod and holding rod, the first support bar at least two, the first support bar is provided with multiple fixed Hole, position and the spring catch in hole, corresponding location, the second support bar is Y shape, and the second support bar is fixed at connecting rod two ends, and second supports Bar bottom is provided with hole, multiple location and the spring catch in hole, corresponding location, and holding rod connects the bottom of the first support bar, holding rod Being provided with multiple vertical through hole, the first post upper is fixing connects supporting part, the first sheathed second support bar in support bar lower end Upper end, sheathed 3rd support bar in bottom of the second support bar, the 3rd support bar is provided with Non-slip material.It provides the benefit that, logical Cross the location in the hole, location of the first support bar and the second support bar, play the effect of crutch extension；By the permeation functions of through hole, Play the effect of air circulation；Increase frictional force by Non-slip material, play the effect preventing skidding.

2, a kind of anti-skid crutch (CN203934764U), including crutch body, described crutch body bottom face is provided with elastic buffer Block, described crutch body bottom is additionally provided with the shoe that can be inserted into described elastic buffer block, and described shoe includes fixing group Part, head rod, the second connecting rod and Antiskid platform, described Antiskid platform is provided with anti-slide opening and anti-slop serrations, described elastic buffer Block can be inserted into described anti-slide opening, and described fixation kit is provided with the first stopper slot and the second stopper slot, described head rod one end Be connected with described Antiskid platform, rotatable first stopper slot that snaps in of the described head rod other end, described second connecting rod one end with Described Antiskid platform connects, and the described second connecting rod other end is rotatable snaps in the second stopper slot.

By the contrast of technical characteristic, above-mentioned crutch structure is complex, and operation inconvenience, non-skid property is general.

Summary of the invention

In place of it is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of design science, the most anti-skidding oxter of structure Crutch.

The present invention solves technical problem and be the technical scheme is that

A kind of Antislip underarm crutch, including armpit subiculum, stay tube, stick stem, in left and right stay tube upper end of two specular Common horizontal is fixedly mounted with armpit subiculum, is fixedly mounted with stick stem between two stay tube bottoms, it is characterised in that: same in stick stem lower surface outer rim Axial uniform interval is provided with draw point with footpath, is set with a rubber sleeve in stick stem bottom, and this rubber sleeve correspondence draw point lower end is all shaped with Through hole, is all coaxially installed with a microsprings in the stick stem installing each draw point, the lower surface of stick stem and rubber sleeve inner face it Between have gap, this gap enough makes rubber sleeve expose the needle point of draw point after being compressed axially.

And, the draw point in the coaxial installation of outer rim of stick stem lower surface is 3-5 root.

And, arc surface is made in described rubber sleeve lower surface.

The present invention with good effect is a little:

This crutch is fixed with 3-5 root draw point stick stem lower surface outer rim is coaxial, is mounted on micro-in the stick stem in each draw point Type spring, the stick stem bottom outside draw point is set with rubber sleeve, and this rubber sleeve correspondence draw point is shaped with through hole, thus achieves rubber Compression during set stress, spring exposes and makes draw point expose stick stem and go to the bottom and prevent crutch from skidding；Meanwhile, elastic draw point is axially stretched Contracting, making crutch is flexible contact when contacting ground, buffered skidding, it is to avoid slipping of crutch.The letter of whole crutch structure Single, it is skillfully constructed, makes easily, use reliable, be the regeneration product of existing crutch, commercially have wide practical use, It is people with disability and patient's preferable crutch product.

Accompanying drawing explanation

Fig. 1 is the structural front view of the present invention；

Fig. 2 is the structural representation (broken section) of Fig. 1；

Fig. 3 is the structure enlarged diagram of the rubber sleeve bottom face of Fig. 1

Fig. 4 is the A portion structure enlarged diagram of Fig. 2.

Detailed description of the invention

The invention will be further described below in conjunction with the accompanying drawings and by specific embodiment, and following example are illustrative, no It is determinate, it is impossible to limit protection scope of the present invention with this.

A kind of Antislip underarm crutch, including armpit subiculum 1, stay tube 2, stick stem 3, at left and right stay tube of two specular Upper end common horizontal is fixedly mounted with armpit subiculum, is fixedly mounted with stick stem between two stay tube bottoms.

The innovative point of the present invention is:

Being provided with 3-5 root draw point 7 at the coaxial uniform interval of stick stem lower surface outer rim with footpath, the present embodiment accompanying drawing is 5；At cane Bar bottom is set with a rubber sleeve 4, and this rubber sleeve correspondence draw point lower end is all shaped with through hole 5, in the stick stem installing each draw point all Being coaxially installed with a microsprings 6, have gap between lower surface and the rubber sleeve inner face of stick stem, this gap enough makes rubber sleeve The needle point of draw point is exposed after being compressed axially.

In order to avoid breakking away, arc surface is made in described rubber sleeve lower surface.

The draw point axial stretching that the present invention is elastic, making crutch is flexible contact when contacting ground, has buffered skidding, it is to avoid Slipping of crutch.
