Description

A kind of height-adjustable crutch

Technical field

This utility model relates to a kind of crutch, particularly relates to a kind of crutch of conveniently adjusted height.

Background technology

Crutch belongs to a kind of power-assisted instrument, by human body being supported to assist human body to walk, be that shank has the personnel of disease to carry out the indispensable instrument of rehabilitation, it also is shank disabled person's tool using, traditional crutch is generally fixed, can not regulate height, this brings inconvenience with regard to the use of giving hospital, this is because hospital generally provides the personnel's use that need carry out rehabilitation to shank, the personnel that use are because of the height difference, then need to have a plurality of crutch of differing heights,, cause use cost to rise to satisfy patient's needs, for this reason, a kind of height-adjustable crutch arises at the historic moment, and like this, patient's needs that a spot of this crutch can satisfy various differing heights only need be purchased by hospital; And on the other hand, patient is using crutch to carry out in the rehabilitation course, also needs to regulate different support forces by the crutch that uses differing heights, is beneficial to rehabilitation.The height-adjustable crutch of prior art, comprise the upper boom and the lower beam that is used to support on ground that are used for directly supporting human body, between its upper boom and the lower beam by this contraction and the elongation of incompatible realization top and bottom that match between snak link and the snap-on hole, highly increase during elongation, during contraction, highly descend, and then reach the purpose of regulating differing heights, this structure is fixed with a slide block on the top of lower beam, both sides at slide block are provided with snak link, and upper boom is a frame body, are provided with some selectable snap-ons hole in the both sides of frame body, slide block slides up and down along two side levers of upper boom frame body, snak link enters different snap-on holes, and is then highly different, but owing to be used for the bottom that is provided in a side of slide block that control spring is pulled work in the existing structure, scalable just after being pulled by spanner handle has caused use extremely inconvenient.

The utility model content

The purpose of this utility model is to overcome the deficiency of prior art, and a kind of height-adjustable crutch is provided, and it is very easy, quick and convenient to make to the adjusting control of snak link.

The technical scheme that its technical problem that solves this utility model adopts is: a kind of height-adjustable crutch, comprise upper frame, lower frame, slide block, upper frame is the frame body structure, a support bar respectively is equipped with in the both sides of upper frame, lower frame is a single pole, the bottom of lower frame is used to land, the top of lower frame and slide block bottom fix, the slide block both sides longitudinally are provided with sleeve, the sleeve sliding sleeve is on the support bar of upper frame both sides, both sides in slide block are along a latch piece laterally respectively is housed, leaning mutually of latch piece to the inner spring of laterally establishing with the edge, it is provided with projection outward, and projection is pushed up mutually with the support bar of upper frame, and the support bar of upper frame is provided with the some selectable pin-and-hole that can match with the latch piece; Top in slide block is provided with and presses piece, press the piece bottom spring of establishing along vertically is housed, be equipped with on the slide block to be used to limit and press the limited block that moves on the piece, the bottom that presses the piece both sides is provided with the projection of band hypotenuse, corresponding on the latch piece, be provided with can with the groove that presses the band hypotenuse that piece matches, the hypotenuse that presses the piece projection reclines mutually with the hypotenuse of latch piece groove.

The middle part is provided with link stopper in the described slide block, and the link stopper both sides respectively are equipped with one along the spring of laterally establishing, and two springs lean mutually with the latch piece of both sides respectively.

Two springs of establishing along vertically are equipped with in the described piece bottom that presses, and two springs are uniformly distributed in and press the piece bottom.

During use, when needs are regulated height, handing down of crutch handshake part is moving with being grasped in, form with grasping grips slide block equally, when hands is exerted oneself downwards, press the effect that piece is under pressure on the slide block, move down, and the vertical and spring established in the edge of pushing its bottom device, when pressing piece and moving down, because pressing the hypotenuse of piece bottom projection reclines mutually with the hypotenuse of latch piece groove, in the folding process, inevitable inclined-plane along subsides mutually inwardly pushes up the latch piece, make the latch piece along laterally in the middle of slide block, moving, when moving in the latch piece, push the spring of laterally establishing with its edge of leaning on mutually on the one hand, its outside projection is by withdrawing from the pin-and-hole on the support bar on the other hand, slide block makes on can carry out along the support bar of upper frame both sides, lower slider, when being adjusted to the height and position that needs, with openhanded the opening that is pressed on the slide block, press piece along popping up under the tensile effect of recovery of the vertical and spring established, until the resistance shelves that run into limited block for this reason, after pressing piece and upspringing, the hypotenuse that presses piece bottom projection leaves the hypotenuse of latch piece groove, makes to press piece the top power of latch piece is disappeared, and then the latch piece can be along outwards ejecting under the tensile effect of recovery of the spring of laterally establishing, till the hypotenuse of projection reclines mutually bottom pressing piece again, at this moment, the outside projection of latch piece can spring in the pin-and-hole on the support bar, makes on slide block cannot carry out along the support bar of upper frame both sides, lower slider, then obtain relative fixed between upper frame and the lower frame, reached the purpose of regulating height.

The beneficial effects of the utility model are, owing to adopt the edge, both sides in slide block one latch piece is housed respectively laterally, the both sides of latch piece respectively are provided with a projection, inside lobe leans mutually with the spring that laterally establish on the edge, outside projection is pushed up mutually with the upper frame support bar at sleeve place, the corresponding some selectable pin-and-hole that can match with latch piece projection that is provided with on the upper frame support bar; Top in slide block is provided with and presses piece, press the piece bottom spring of establishing along vertically is housed, press to be equipped with on the slide block of dual-side of piece to be used to limit and press the limited block that moves on the piece, the bottom that presses the piece both sides is provided with the projection of band hypotenuse, the corresponding groove that on the latch piece, is provided with the band hypotenuse that can match with the projection that presses piece, the hypotenuse that presses the piece projection reclines mutually with the hypotenuse of latch piece groove, by matching along spring of vertically establishing and the horizontal spring of establishing in edge, and the matching of hypotenuse of hypotenuse and the groove of latch piece that presses the projection of piece, make to press piece and can control to the mobile of latch piece, so realized cooperating between latch piece and the upper frame support bar pin-and-hole quick, convenient and very easy.
