Abstract

The utility model relates to a clamping and fixing structure of a foldable wheel chair, which comprises a clamping and fixing piece and a linkage rope to be arranged on the foldable wheel chair to be used for solving the disadvantage that the foldable wheel chair is not convenient to fold, wherein the clamping and fixing piece is pivoted on a chair back rod of the foldable wheel chair, and a positioning notch is arranged on the clamping and fixing piece. The linkage rope is fixedly connected with the clamping and fixing piece to be used for linking the clamping and fixing piece to enable the clamping and fixing piece to rotate by using a pivoting point as a center to be buckled, clamped and fixed by a positioning section which is arranged on the positioning notch corresponding to a rear wheel rod of the foldable wheel chair.

Description

But the clamping structure of folding wheelchair

Technical field

But this utility model is the clamping structure about a kind of folding wheelchair.

Background technology

In folding wheelchair now, be that case before a kind of relevant shown in No. the 547072nd, Taiwan patent announcement is arranged, this structure is under the support exhibition or folding, all be to utilize the connection tube that is arranged between pin joint seat and callosity pipe to control, it in this connection tube the pin rod of establishing tool one controlled lever linkage, and be to establish the fixed block that tool one is established the tool locating hole in the pin joint seat, open up under normality in support, pin rod in this connection tube is in the locating hole that fastens on pin joint seat internal fixation piece, make wheelchair form the support exhibition, and when folding, the pulling control stick make its linkage pin boom end recess the locating hole of fixed block before then needing, thus, can be for folding wheelchair.

Yet the above-mentioned suitable Djumah of mode that folds is tired, mainly is to be the latent seat cushion below that places because of this control is relevant, thus in need in the folding seat cushion started find out control stick after, can spur control stick and give folding, fold suitable the trouble.

Add, this wheelchair is on clamping structure, and required spare part is quite various, not only improves manufacturing cost, also increases relatively and assembles man-hour.

The utility model content

But this utility model is the clamping structure about a kind of folding wheelchair, be to fix disappearances such as the various and assembling of the member of locating structure is difficult for for solving above-mentioned known folding wheelchair, simultaneously, more can simplify the action that folds of traditional folding wheelchair, fold more quick and convenient with order.

For achieving the above object, solution of the present utility model is: but the clamping structure of folding wheelchair, and it is to comprise fixing sheet and interlock rope, and is arranged on the skeleton of folding wheelchair, wherein: fixing sheet is to be hubbed to form pivoting point on the skeleton, and establishes the tool positioning recess in fixing on the sheet; The interlock rope is with to fix sheet fixed, and fixing sheet in order to interlock, to make it be center and turn with the pivoting point, fixes and fasten with the relative skeleton of its positioning recess.

Be to establish the controller that tool one is strained or loosened in order to control interlock rope on this interlock rope.

But should be that correspondence fixes the positioning recess of sheet and establishes the tool positioning section on the skeleton of folding wheelchair.

After adopting such scheme, this utility model can see through clamping structure and be fixed the location, and can fold its designs simplification fast and simple and easy when folding at the wheelchair of folding after wheelchair support.

The specific embodiment

As shown in Figure 1, 2, 3, this utility model is to comprise fixing sheet 1 and interlock rope 2, and is arranged on the skeleton 3 of folding wheelchair, wherein:

Skeleton 3 is to comprise chair back bar 31, seat support bar 32, rear wheel bar 33, front wheel bar 34, connecting rod 35,35 ' and shadoof 36, this chair back bar 31 is to articulate with front wheel bar 34, and on chair back bar 31, extend a shadoof 36 that connects two sides, and the pin-jointing piece 311 that is pivoted in the lower end of chair back bar 31, in order to do to articulate rear wheel bar 33, and on rear wheel bar 33, establish tool one suitable long positioning section 331{ in present embodiment, this positioning section 331 is that to lift the member that is provided with separately be example, also can be on reality is implemented by skeleton 3 on 33 of the rear wheel bar of two sides directly extend be formed by connecting; Be to be respectively equipped with a connecting rod 35,35 ' between seat support bar 32 and front wheel bar 34 and front wheel bar 34 and the rear wheel bar 33 again;

Fix sheet 1 and be on the chair back bar 31 that is hubbed at skeleton 3 and form pivoting point 11, and establish tool positioning recess 12, and fasten fixings with the positioning section 331 of set tool on the rear wheel bar 33 of its positioning recess 12 relative skeletons 3 in fixing on the sheet 1.

Interlock rope 2 one ends are to be connected with fixing sheet 1, the other end then wears on the shadoof 36 that is positioned skeleton 3, and join with a controller 21 that is arranged at the upper end of chair back bar 31, see through the holding of controller 21, put controlled interlock rope 2 and interlock to fix sheet 1 be center and turn with pivoting point 11.

Borrow it, when the support exhibition is located under normality, be to make this be hubbed at fixing sheet 1 on chair back bar 31 and the rear wheel bar 33, directly fasten on the positioning section 331 that convexedly stretches in rear wheel bar 33 with its positioning port 12, and chair back

bar

31 and 33 of rear wheel bar are able to by the support that fixes sheet 1, make it be supportted the exhibition location to each other; Because fixing the positioning recess 12 of sheet 1 is that direct and firm embedding is butted on the positioning section 331, its location to each other is quite certain, does not exist and do not have the unexpected danger that causes folding that breaks away from.

As when the folding, shown in Fig. 4,5, be directly to hold to controller 21 to make this interlock rope 2 of its interlock and turn fixing sheet 1, it will be center of rotation and turn with its pivoting point 11 that order fixes sheet 1, cause the positioning recess 12 that fixes sheet 1 recessed positioning section 331 on the rear wheel bar 33 form separate the state of tearing open after, make chair back bar 31 relative rear wheel bar 33 and front wheel bar 34 amount to again and abut against, in order to do to dwindle the person that amounts to the volume.

And the shadoof 36 that chair back bar 31 rear ends of skeleton 3 are extended is to be available for users to directly extract whole skeleton 3, takes passerby in order to do being beneficial to transport.

The above person of thought, it only is preferred embodiment of the present utility model, when not limiting the scope that this utility model is implemented with this, promptly the simple equivalent of doing according to this utility model claim and novel description generally changes and modifies, in should still belonging to the scope that this utility model patent contains.
