Description

The flexible structure of adjusting of wooden crutch

Technical field

The utility model relates to a kind of flexible adjustment structure of crutch, particularly relates to a kind of flexible adjustment structure that is used for wooden crutch.

Background technology

General wooden crutch has the hand of confession usually and grips horizontal grip part, and vertically one-body moldedly be stock form and cane body with regular length, this known wooden crutch not only takes up space and causes the inconvenience of taking in, for user's behaviour in service itself, everyone height difference, hold the discomfort of taking and inconvenience if use the wooden crutch of same length also can produce, height the higher person for example, must just can hold this grip part and the bad problem of posture is arranged slightly to stoop waist, otherwise, the shorter person of height, then may select to be gripped on the place of contiguous this grip part of cane body because the grip part is higher, but the grip strength of the elderly's hand is limited, so grips mode and can't really provide the user effectively to lean on.

In order to address the above problem, there is the dealer to develop the wooden crutch of disassembled one-tenth more piece individual member, though be easy to take in, so for the elderly, take out at every turn and all want recombinant once to increase use inconvenience on foot when using; In addition, also there is the dealer to develop to utilize elastic threads to wear the more piece separating member and is combined into a kind of foldable crutch, but such crutch structure, owing to the component inside that respectively saves of forming the cane body must be offered through hole to wear this elastic threads, and being easy to generate the crack in the process of offering through hole, wooden material influences its structural strength, have doubt safe in utilization when implementing, therefore the crutch material of reaching the folding effect by elastic threads on the market only is confined to the material of metal.

By this, known wooden crutch structure still has the space of improvement in the purpose of reaching tool adjustment effect.

The utility model content

The technical problems to be solved in the utility model provides the flexible structure of adjusting of a kind of wooden crutch, to solve above-mentioned use problem, designs the wooden crutch that reaches adjustment length function with stretch mode.

For solving the problems of the technologies described above, the flexible structure of adjusting of a kind of wooden crutch of the present utility model, comprise that a cane head and a rosette and a screw rod are affixed, a sleeve pipe and this rosette are affixed and be equipped with this screw rod and a cane body, and a forcing piece and a closure are sheathed on this cane body surface; Wherein:

This cane head has from a set to the concave neck of an affixed groove of end face;

This rosette has that one first end face is affixed with this neck finish, one second end face and a perforation run through this biend and be communicated with this group-connecting groove; And this first end face diameter is less than this second end face diameter

This screw rod has two ends, wherein in this group-connecting groove of ccontaining this perforation that is fixedly arranged on this rosette of an end and this cane head;

This inside pipe casing has an extendable room, and one end and this rosette second end face are affixed and be equipped with this screw rod, and this sleeve pipe is held in addition in inner peripheral and is provided with an annular conical surface;

This cane body has two ends, and wherein an end end face is arranged with an elongated slot along this cane body, and this elongated slot is equipped with an internal thread in the adjacent openings place; This cane body is placed in this extendable room of this sleeve pipe, and this screw rod is arranged in this elongated slot and this internal thread and this screw engages, makes this cane body along the turn displacement in this sleeve pipe of this screw rod;

This forcing piece is circulus and is sheathed on this cane body surface that its outer peripheral face is formed with this annular conical surface of a taper surface and this sleeve pipe and replaces;

This closure is arranged with a group-connecting groove; This closure lock knot and this cannula lock knot, ccontaining this sleeve pipe of this group-connecting groove in addition end and its bottom land is worn for this cane and is established, this taper surface of this forcing piece tightens for the compacting of this sleeve ring conical surface and this group-connecting groove bottom land and is packed in this cane body surface, and this cane body and this thimble joint are fixed.

By this, by establishing this internal thread and this screw engages in this cane body inside, for ccontaining this screw rod, make this cane body with this elongated slot, and reach the flexible main purpose that this crutch length meets user's height, increases comfort of adjusting along the turn displacement in this sleeve pipe of this screw rod; In addition, between this cane body and this sleeve pipe, this forcing piece by the tool taper surface cooperates with the annular conical surface of this sleeve pipe ora terminalis, when this closure and this cannula lock knot, because this annular conical surface is suppressed in this taper surface, make this forcing piece deflation and be packed in this cane body surface, promptly reach the fixing locating effect of this cane height degree.
