Abstract

The utility model discloses one and can adapt to various road surface, and old man's walking stick of good stability, it relates to daily living article technical field; Self-aligning bearing (2) loads in the cylindrical sleeve hole that is fixedly connected with base (4) by its outer ring, with the walking stick bar (1) of handle one, insert in the inner ring hole of self-aligning bearing (2), self-aligning bearing (2) is enclosed in the cylindrical sleeve on base (4) by bearing cap (3), and base (4) bottom is fixedly connected with three contacts that land; The utility model structure is simple, reasonable in design, by self-aligning bearing (2) have with External Force Acting, in certain limit, the characteristic of its mutual angle and direction can be adjusted arbitrarily between Internal and external cycle, no matter user is gone up a slope or descending, or on the road surface of uneven, can with optimum angle out of strength direction, rely on the three points of contact of walking stick, more safely and smoothly walk.

Description

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

Technical field

The utility model relates to daily living article technical field, is 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 purpose of this utility model 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 touchdown points are formed, solve user with best angle direction firmly, and the contradiction that three or more points lands between the high stability brought.

In order to the problem existing for technical solution background, the utility model have employed 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; Cylindrical sleeve endoporus on base and self-aligning bearing outer ring adopt matched in clearance bonding, or adopt interference fit to connect, and form tight fit; Walking stick bar end portion and self-aligning bearing inner ring hole adopt interference fit to be connected, or adopt matched in clearance bonding, 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 utility model: 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 utility model 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 utility model 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.

Cylindrical sleeve endoporus on base and self-aligning bearing outer ring adopt matched in clearance bonding, form tight fit.

Walking stick bar end portion and self-aligning bearing inner ring hole adopt interference fit to be connected, and 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.
