Abstract

The utility model relates to a folding table support frame. The positions of the four corners of the tabletop support rod in each unit are respectively provided with a vertical support rod (2). Each lateral face is provided with an X-shaped support frame (5) which is formed by the crossed hinge of two support rods. Corresponding end heads at the lower parts of the X-shaped support frames of two adjacent lateral faces are hinged with a bottom hinge head (4) which is fixed at the lower part of the vertical support rod (2). Corresponding end heads at the upper part are hinged with a sliding hinge head (3) which is sheathed on the vertical support rod (2) in sliding fit mode. The support of the utility model is stable, and the utility model can be combined into a folding support frame with a high-low stage structure.

Description

Supporting frame of foldable table

The utility model belongs to a kind of supporting frame of foldable table.

Existing supporting frame of foldable table structure usually as shown in Figure 2, promptly the X-shaped support that is formed by two support bars intersection hinges is respectively done four sides, the mutual hinge in the corresponding termination of the X-shaped support of every adjacent two sides forms folding flex point, during use, with desktop and four folding flex point relative fixed above the bracing frame.The weak point of this structural supporter is: desktop gravity and vertically to power all act on the X-shaped support of each side, the X-shaped support is subjected to vertically behind active force, the termination on top promptly can be pressed towards down motion, so lean on the Horizontal Tension of coming the balanced support frame to be subjected to the relatively-stationary desktop in termination, top, make bracing frame keep the state of open support, this structure is stable inadequately.

The utility model aims to provide the more stable supporting frame of foldable table of a kind of structure.

The technical scheme that realizes above-mentioned purpose is: the utility model is respectively equipped with vertical support bar (2) at unit mesa supports frame (9) corner location, each side is provided with the X-shaped support (5) that is formed by two support bars intersection hinges, the corresponding termination hinge of X-shaped support bottom, adjacent two sides is in the same bottom hinge head (4) that is fixed on vertical support bar (2) bottom, and the corresponding termination hinge on top in the same slide hinge head (3) that is enclosed within on the vertical support bar (2) with being slidingly matched.

The utility model can be made up of a said units mesa supports frame, also can combine by plurality of units mesa supports frame, and when combining by a plurality of unit supports framves, a shared side, per two assembled unit junctions.

During use, desktop is fixed on the vertical support bar top that struts, when needing to fold, four vertical support bar are drawn close to the center, and side X-shaped support upper end can be along the upwards folding thereupon gathering of slip of vertical support bar.

The utility model by vertical support bar bear vertically to power, so supporting ﹠ stablizing, and the X-shaped support of slide hinge head hinge can be with the folding gathering of whole bracing frame on side and the vertical support bar.

Short unit supports frame of hinge head 7-upper hinge head 8-9-unit mesa supports frame under the 6-

10-cross bar 11-desktop 12-fixed cover

Embodiment 1:

This example is provided with a unit mesa supports frame 9, the bracing frame corner location is provided with vertical support bar 2, the vertical support bar bottom is fixed with bottom hinge head 4, the upper end is fixed with desktop fixed block 1, the middle part is with slide hinge head 3 with being slidingly matched, four sides are provided with the X-shaped support bottom two corresponding termination hinges of X-shaped support 5, two adjacent sides of middle hinge in the same bottom of vertical support bar 2 bottoms hinge head 4, and top two corresponding termination hinges are in same slide hinge head 3.

This routine unit mesa supports frame 9 also connects one short unit supports frame 8, its structure is: the X-shaped support that forms by two support bar middle hinge form short unit supports frame leading flank and two beside, short unit supports frame trailing flank is shared with the leading flank of coupled described unit mesa supports frame 9, on the X-shaped support rear portion of two beside, lower end is connected with bottom hinge head 4 hinges with the slide hinge head 3 on the corresponding vertical support bar 2 of coupled unit mesa supports frame 9 respectively, on the X-shaped support front portion of two beside, lower end is connected with following hinge head 6 hinges with the corresponding upper hinge head 7 of leading flank X-shaped support respectively.

Hinge head on this routine unit mesa supports frame 9 is provided with the vertical jack that can insert vertical support bar 2, be provided with simultaneously be mutually an angle of 90 degrees vertically to hinge wall, the support bar difference hinge of adjacent side is in the respective hinge wall, the vertical jack of slide hinge head 3 is a both ends open, can on vertical support bar, slide like this, desktop fixed block 1 downside on vertical support bar top is provided with the jack of vertical support bar, it is two parallel to each other and stretch out the wall at fixed block edge that upper side is provided with, the upper hinge head of short unit supports frame with short unit supports frame connecting place vertical support bar on slide hinge head 3 upper sides also be provided with two parallel and stretch out the wall at hinge head edge.

When desktop is installed, between two the desktop fixed blocks in mesa supports frame vertical support bar upper end, load onto a cross bar 10, the cross bar two ends embed respectively between the desktop fixed block two parallel walls, also adorning a cross bar 10 respectively between short the unit supports frame two slide hinge heads and between the two upper hinge heads 7, the cross bar two ends are respectively between the insert hinge head set two parallel walls, the desktop bottom of energy elastic elongation is provided with fixed cover 12, desktop fixed cover 12 is enclosed within on the parallel wall termination of stretching out the hinge head edge, be about to desktop and divide and be fixed in addition on unit mesa supports frame and short the unit supports frame, form the folding table of height mesa structure shown in Figure 5.

The utility model can not only improve the stability of bracing frame, but but also the high low platform supporting construction that can fold shown in the design cost embodiment.

Embodiment 2:

This example also is the bracing frame of high low platform structure, and its high platform bracing frame is made up of two units folded bracing frames, and each units folded support frame structure is with embodiment 1.
