The flexible non-skid walking stick is convenient to be folded, collected and placed. The flexible non-skid walking stick is light, and the flexible non-skid walking stick is suitable for the disabled person to carry on the occasion of taking a vehicle and to use after getting off vehicle. The flexible non-skid walking stick is a new walking aid tool.

Description

Flexible non-skid walking stick

The walking apparatus tool that a kind of people with disability uses, particularly portable scalable on-slip crutch.

As everyone knows, crutch is the indispensable walk-aiding tool of the people of legs and feet deformity, and general crutch mostly is wooden now, can not fold, along with growth in the living standard, when going out, quite a few people with disability use handcar or motor vehicles to ride instead of walk, and crutch carries very inconvenient while taking a bus.

The purpose of this utility model provides a kind of scalable so that carry, and crutch that can on-slip.

This utility model is achieved in that scalable on-slip crutch comprises the support mechanism on cane body and top thereof, the handle mechanism at cane body middle part and the on-slip device of lower end.The cane body is to be made by two sections light metal tubing, and following pipe can be inserted in pipe, and detent mechanism is arranged.The flexible snap switch of control sleeve pipe is arranged in the support mechanism of cane body; Cane body middle part handle mechanism comprises the clamping device after the cane body sleeve pipe of the handle folding device of the spring location rod-type that is contained in the handle jacket and circlip type shrinks; The on-slip device of cane body lower end is flexible screw-type.

This utility model is made of aluminium alloy, and is in light weight, collapsible, flexible, volume, length are all very little, and retractable freely, is convenient to carry when the people with disability rides, using behind car, and also unlikely the slipping of walking in the ice and snow sky, is a kind of walk-aiding tool of benefiting for the people with disability.

Details of the present utility model is provided by following examples and accompanying drawing thereof:

Fig. 1 is this utility model outside drawing.

Fig. 2 is a kind of structural representation on this utility model top.

Fig. 3 is a kind of structural representation at this utility model middle part.

Fig. 4 is a kind of structural representation of this utility model lower end.

With reference to the accompanying drawings: present embodiment comprises the cane body, relies on mechanism, handle mechanism, on-slip device.

The cane body is made up of last arm 1 and lower branch line 28, and lower branch line 28 can be packed into and be gone up in the arm 1, and the upper inside wall of lower branch line 28 is fixed with nut 13, long cover 14 and interstage sleeve 15 successively, is wedge bayonet lock 16 axial limitings of below.On lower branch line 28 walls of the position suitable with interstage sleeve 15 lower planes, detent mechanism is arranged, it comprises three uniform square holes, round spring 17 bindings of 16, three wedge bayonet locks of three wedge bayonet locks, 16 usefulness is housed respectively tightens.There is a circumferential slit D appropriate location, last arm 1 bottom, and its length is about 1/3rd～four of circumference, and width can stick into jump ring 12.

The support mechanism of upper end is by a housing of being made up of last cover 20 and arc support plate 21, on arc support plate 21, be fixed with support 22, spanner 26 is lever-type, it is a fulcrum with the hinge 24 of support 22, its end face is propped up by the screw on the support 22 23, be connected to steel wire rope 19 below, spring 25 is enclosed within outside the steel wire rope and is clipped between arc support plate 21 and the spanner 26.Steel wire rope 19 lower ends hitch taper ferrum 18, and taper ferrum 18 duties withstand on the place, inclined-plane of wedge bayonet lock 16.

The middle part handle mechanism comprises handle jacket 6, and the outer end is welded with plug 11, and locating rod 5 joins with screw thread and plug 11, and spring 8 is enclosed within the step place on the locating rod 5, and locating rod is withstood, and its head is injected be welded in the groove of the fixed block 2 on the arm 1.Interior cover 7 left ends are welded in and change on the ferrum 4, and right-hand member has annular groove, and the circle 10 that is installed withstands spring 8 by block 9.Change totally two of ferrum 4, be contained in axle 3 ends of fixed block 2 both sides respectively, can be around axle 3 rotations.Two are changeed ferrum 4 bottoms and are fixed with a jump ring 12.

The structure of lower end on-slip device is: the terminal outer wall of pipe 31 has an annular groove down, connects little cover 29 with three pins 31, and nut 27 is welded in the bottom of little cover 29, and nut is passed in the tip of screw 32, and overcoat 30 and little cover 29 are fastening.The round end of screw 32 is milled with vertical plane, withstands the plane with jackscrew 33, and it can not be rotated.

During normal the use,, block arm 1 to steel wire rope 19 tensions because the effect of spring 25 makes taper ferrum 18 upwards force wedge bayonet lock 16 outside.Handle jacket 6 is pulled upwardly from folding position A, and locating rod 5 heads are deviate from from the A groove of fixed block 2, forwards in the work nest at B place, and commentaries on classics ferrum 4 props up arm 1 and can use.

During folding carrying, lift spanner 26, compression spring 25 loosens steel wire rope 19, and taper ferrum 18 moves down, and wedge bayonet lock 16 shrinks to the center under the effect of circle spring 17, thereby lower branch line 28 be may be collapsed in the arm 1.Skid off for after preventing to shrink, be provided with jump ring 12, block lower branch line 28 from the slit D of last arm 1, when retraction handles was located by B to A, jump ring 12 promptly moved to slit, D place with changeing ferrum 4 by the C place.

When needing on-slip, rotary sleeve 30, little cover 29 and nut 31, this moment, screw 32 can not be rotated by jackscrew 33 restrictions, thereby shifted out downwards outside the cover, can play the on-slip effect.Do not need the time spent, reverse rotation overcoat 30, ailhead are promptly recoverable.
