The specific embodiment

Below by the specific embodiment, the utility model will be further described.

Referring to figs. 1 through Fig. 6, a kind of folding bedstead, comprises two groups of cross bars 20 and three groups of feets, comprising two groups of outer support pin 101 and one group of inner support pin 102 that are positioned at cross bar 20 middle parts that are arranged at respectively cross bar 20 two ends.Every group of feet comprises that two are articulated and connected and mutual montant 10 arranged in a crossed manner, and this two montant 10 can relatively be packed up or open.This montant 10 comprises vertical section of 10a and the section of the bending 10b that is positioned at vertical section of 10a top, and the two-combats curved segment 10b of this two montant 10 is bending in opposite directions.The section of bending 10b is the crooked certain angle a of section 10a relatively vertically, and this angle a is half of the two montants 10 angle b that two vertical sections of 10a form while packing up, and two-combats curved segment 10b realizes face contact.The section of the bending 10b top of this two montant 10 is all articulated and connected by connector and two groups of cross bars 20.

Wherein, every group of cross bar 20 includes the first bar 21 and the second bar 22, these the first bar 21 the inners, the second bar 22 is inner all by one first connector 31, is articulated and connected with a top of inner support pin 102, makes this first bar 21 and the second bar 22 can relative folding downwards or open.Two second connectors 32 are passed through respectively with wherein outer support pin 101 two ends, top are hinged in two first bar 21 outer ends of these two groups of cross bars 20, two second bar 22 outer ends of two groups of cross bars 20 are hinged by two second connectors 32 and other two ends, feet top respectively, and the relatively inwardly folding or open of this two outer supports pin 101.

Further, the first connector 31 comprises two T shape iron plates and is connected in the block 31a between two T shape iron plate homonymies, and this block 31a can increase stability.These two ends, T shape iron plate top are hinged with the first bar 21 and the second bar 22 respectively, and this T shape iron plate bottom is connected with inner support pin 102.

Further, the second connector 32 comprises two L shaped iron plates, this L shaped iron plate top and the first bar 21 or the second bar 22 are hinged, bottom is connected with outer support pin 101, and L shaped iron plate top inner surface is provided with some salient point 32a, on the first bar 21 and the second bar 22, correspondence is provided with shrinkage pool 23, and salient point 32a embeds shrinkage pool 23 when feet 101 is opened outside, thereby improves the stability of connecting portion between the first bar 21, the second bar 22 and montant 10.

Each montant 10 of the present utility model is a whole joint, without more piece is set.In use, with reference to Fig. 1, the first bar 21 and the second bar 22 are opened, and inner support pin 102 and outer support pin 101 are also opened, and two montants 10 are open configuration, on cross bar 20, place mattress.With reference to Fig. 7 to Figure 11, during folding, first two montants 10 of each feet are packed up, then two outer support pin 101 are inwardly folded to and are close to cross bar 20, then, by the first bar 21 and the downward folding of the second bar 22, make two outer support pin 101 be close to inner support pin 102.
