Abstract

The invention discloses a walking stick used for the aged and suitable for various road surfaces, and relates to the technical field of daily necessities. The walking stick is good in stability. A self-aligning bearing (2) is installed in a cylindrical sleeve hole through an outer ring of the self-aligning bearing, wherein the cylindrical sleeve hole is fixedly connected with a base (4). A walking stick rod (1) integrated with a handle is inserted into an inner ring hole of the self-aligning bearing (2). A bearing cover (3) is used for closing the self-aligning bearing (2) into a cylindrical sleeve on the base (4). Three landing contacts are fixedly connected to the lower portion of the base (4). The walking stick is simple in structure and reasonable in design; with the help of the characteristic of the self-aligning bearing (2) that along with the effect of external force, the mutual angle and the direction between an inner ring and the outer ring can be adjusted at will within certain limitation, no matter when a user goes up or comes down a hill, or walks on a bumpy road surface, with the most suitable exerting angle and direction, the user can depend on three points of the walking stick to land and walk more safely and stably.

Description

The novel sticks for old man on various road surface can be adapted to

Technical field

The present invention relates to daily living article technical field, be specifically related to a kind of novel old man's walking stick.

Background technology

Walking stick is a kind of simple apparatus of auxiliary walking, and normally wooden or metal rod is made, and it mainly serves as third leg when old man walks.

Walking stick like traditional rod straight up and down, because it is that single-point lands, less stable, security is bad.

Or 4 walking sticks landed are there are on the market at 3 now, although its good stability of such walking stick, but between ground level with walking stick bar vertical is fixedly connected with, cause user when going on downhill path or potted road surface, the inclination angle that between health upright when walking stick bar is walked from people, meeting angle presentation is different, direction is different, this firmly brings inconvenience for user over the ground for the multiple spot plane by walking stick, finally keep optimum orientation to exert oneself under prerequisite, single-point or 2 land, and this just makes again the advantage of the good stability of 3 or 4 walking sticks landed lose.

Summary of the invention

The object of this invention is to provide a kind of various road surface of adapting to, and the novel sticks for old man of good stability, its structure is simple, reasonable in design, self-aligning bearing is loaded between the plane that walking stick bar and three or more touchdown points are formed, solve user with best angle direction firmly, and the contradiction between three or more the high stabilities brought with lighting.

In order to solve the problem existing for background technology, present invention employs following technical scheme: it have employed walking stick bar, self-aligning bearing, bearing cap, base with handle one, bearing cap there is diameter slightly larger than the centre bore of walking stick bar external diameter, its lower surface has the boss of ring-type, base is fixedly connected with cylindrical sleeve, and three contacts that land; Adopt matched in clearance adhering method, by the outer peripheral surface of self-aligning bearing, self-aligning bearing is loaded in the cylindrical sleeve hole on base, form tight fit; Adopt interference fit, walking stick bar end portion is loaded in the inner ring hole of self-aligning bearing, form tight fit; Bearing cap is fastened on the upper end of the cylindrical sleeve on base, is closed by self-aligning bearing, and the annular boss of its lower surface contacts with the cycle surface of self-aligning bearing.

Operation principle of the present invention: the widely used self-aligning bearing in mechanical industry field, it is a kind of standard component of production in enormous quantities, the characteristic that it has is: in normal operation, with the effect of external force, its mutual angle and direction can be adjusted arbitrarily in certain limit between the Internal and external cycle of bearing, and not very big axial force can be born.

The present invention has following useful effect: its structure is simple, reasonable in design, take full advantage of characteristic that mechanical industry field is produced in enormous quantities, widely used standard component self-aligning bearing, achieve on level road, non-horizontal road surface, or potted road surface, user can constantly to change, and optimum angle direction, by the advantage that three points of contact walking stick stationarity is good, the object of more safely and smoothly walking.

Detailed description of the invention:

Referring to Fig. 1, Fig. 2, Fig. 3, the present invention adopts following detailed description of the invention: it have employed walking stick bar 1, self-aligning bearing 2, bearing cap 3, base 4 with handle one, bearing cap 3 there is diameter slightly larger than the centre bore of walking stick bar 1 external diameter, and lower surface is with annular boss, base 4 top is fixedly connected with cylindrical sleeve, and bottom is fixedly connected with three contacts that land.

Adopt matched in clearance adhering method, by the outer peripheral surface of described self-aligning bearing 2, self-aligning bearing 2 is loaded in the cylindrical sleeve hole on base 4, form tight fit.

Adopt interference fit, by the end portion of described walking stick bar 1, load in the inner ring hole of self-aligning bearing 2, form tight fit.

Described bearing cap 3, utilize centre bore to pass upper end that walking stick bar 1 is fastened on the cylindrical sleeve on base 4, closes self-aligning bearing, the annular boss of its lower surface and the upper-end contact of self-aligning bearing 2 outer ring.

The operation principle of this detailed description of the invention: the widely used self-aligning bearing in mechanical industry field, it is a kind of standard component of production in enormous quantities, the characteristic that it has is: in normal operation, with the effect of external force, its mutual angle and direction can be adjusted arbitrarily in certain limit between the Internal and external cycle of bearing, and not very big axial force can be born.

This detailed description of the invention has following useful effect: its structure is simple, reasonable in design, take full advantage of characteristic that mechanical industry field is produced in enormous quantities, widely used standard component self-aligning bearing, achieve on level road, non-horizontal road surface, or potted road surface, user can constantly to change, and optimum angle direction, by the advantage that three points of contact walking stick stationarity is good, the object of more safely and smoothly walking.

Claims

1. can adapt to the novel sticks for old man on various road surface, it is characterized in that: it comprise with the walking stick bar (1) of handle one, self-aligning bearing (2), with centre bore and lower surface have the bearing cap of annular boss (3), be fixedly connected with cylindrical sleeve, and have the base (4) of three contacts that land.

2. the novel sticks for old man adapting to various road surface according to claim 1, it is characterized in that: the cylindrical sleeve endoporus on described base (4) adopts matched in clearance bonding with self-aligning bearing (2) outer ring, or adopt interference fit to connect.
