A kind of bracing frame

Technical field

The utility model relates to the technical field of bracing frame, and is special relevant with the support frame structure of folding bed.

Background technology

In the prior art, the support frame structure that a kind of folding bed arranged as shown in Figure 1, at least articulate by pivot seat 3 ' by column 1 ', side lever 2 ' and form support body, the upper/lower terminal of every root post 1 ' is separately fixed on the corresponding up and down pivot seat 3 ', side lever 2 ' intersects in twos and is articulated, the upper/lower terminal of every side lever 2 ' is articulated in respectively on the corresponding upper and lower pivot seat 3 ' of intersection, lays mat at the end face of support body, promptly constitutes folding bed.

For an end that makes mat can be propped, make things convenient for the user back to rely on, between two side levers 2 ' of this end left and right sides of support body, also respectively be provided with a strut 4 ', the lower ending pivot of this strut 4 ' is connected on the side lever 2 ', intert in a trepanning of two sliding sleeves 5 ' in the stage casing, another root side lever 2 ' interts in another trepanning of two sliding sleeves 5 ', (this is common structure to have the locking positioning device on this pair sliding sleeve 5 ', not shown), by this locking positioning device two sliding sleeves 5 ' are positioned on strut 4 ' and another root side lever 2 '.In order to make mat be propped up the unlikely wrinkle that occur in back, the top of strut 4 ' also be nested with one telescopic in pipe 6 ', when strut 4 is propped up, interior pipe 6 ' can be pulled out, to prolong bearing height, more open and more flat after mat is propped up.

Like this, remove the locking positioning of locking positioning device to two sliding sleeves 5 ', strut 4 ' is depressed or propped up, drive two sliding sleeves 5 ' and go up slip at strut 4 ' and side lever 2 ', strut 4 ' can be depressed into and abut against side lever 2 ' next door, mat is lain on the end face of support body, perhaps strut 4 ' is supportted to the appropriate location, by the locking positioning device two sliding sleeves 5 ' are positioned on strut 4 ' and another root side lever 2 ', even be positioned at the appropriate location in strut 4 ' support, make mat be able to be propped up, make things convenient for the user back to rely on.

But the bracing frame of this structure is because the lower ending pivot of strut 4 ' is connected on the side lever 2 ', and strut 4 ' interts in the trepanning of sliding sleeve, next spacing by trepanning, can be propped up or be depressed in order to make strut 4 ', must adopt two sliding sleeves 5 ', and, in order to have enough height of propping up, manage 6 ' in also must being with in the strut 4 ', so, structure is comparatively complicated, and cost is also higher.

The utility model content

The purpose of this utility model is to be to provide a kind of simple in structure, bracing frame that cost is low.

In order to achieve the above object, solution of the present utility model is:

A kind of bracing frame, at least by column, side lever articulates by the pivot seat and forms support body, on every root post, following two ends are separately fixed on the corresponding up and down pivot seat, side lever intersects in twos and is articulated, on the every side lever, following two ends be articulated in respectively intersect corresponding on, on the following pivot seat, between two side levers of the support body one end left and right sides, also respectively be provided with a strut, wherein, the lower end of this strut directly is articulated on the single sliding sleeve, a side lever interts in the trepanning of this single sliding sleeve, has the locking positioning device that can be located on side lever on single sliding sleeve, one end of the stage casing of this strut and a gag lever post articulates, and the other end of this gag lever post is articulated on another root side lever.

After adopting said structure, when the utility model uses, remove the locking positioning of locking positioning device to single sliding sleeve, strut is depressed or propped up, drive singly to slide on the side lever and slide, strut can be depressed into and abut against the side lever next door, the mat that is layered on the support body is lain on the end face of support body, perhaps strut is supportted to the appropriate location, single sliding sleeve is positioned on the side lever by the locking positioning device, and by the position-limiting action of gag lever post, is positioned at the appropriate location even support at strut, make the mat that is layered on the support body be able to be propped up, make things convenient for the user back to rely on.

The utility model is owing to the lower end of strut directly is articulated on single sliding sleeve, and it is spacing by gag lever post, and, in order to have enough height of propping up, can single sliding sleeve is upwards sliding as much as possible, and pipe in not needing to increase in addition, so, pair sliding sleeve of the prior art relatively and interior Guan Eryan, structure is obviously simple, and cost is also lower.
