The spike (2) fixing with back flap hinge (1), described spike (2) one end is placed in interior mounting blocks (12) " u "-shaped opening, and the side of a spike (2) is provided with the screwed hole suitable with installing hole II.
Further being improved by, the sidewall of outer mounting blocks (11) the " u "-shaped opening side of described spacing bearing pin (4) correspondence position forms and moves the arcuation stopper slots (111) in 90 degree of expansion by outer mounting blocks (11) and interior mounting blocks (12) for spacing bearing pin (4).
Further it is improved by, the two ends of described arcuation stopper slot (111) form for spacing bearing pin (4) access aperture (112) that accesses respectively, and spacing bearing pin (4) is extended with diameter less than spacing bearing pin (4) and can the elongated end (42) of movement in the arcuation stopper slot (111) between access aperture (112) in access aperture (112) outside.
Further it is improved by, all sides that described spacing bearing pin (4) limits in space in interior mounting blocks (12) " u "-shaped opening form flange collar (41), and the spacing bearing pin (4) between flange collar (41) and interior mounting blocks (12) medial wall is provided with the back-moving spring (5) of coaxial layout.
Further being improved by, the earth terminal of described spike (2) is fixed with plastics rubber cushion (6).
The invention has the beneficial effects as follows: the outer mounting blocks all " U "-shaped by cross section and interior mounting blocks constitute back flap hinge, its China and foreign countries' mounting blocks is fixed with sofa body, interior mounting blocks is fixed with a spike, the end accommodation of interior mounting blocks in the " u "-shaped opening of outer mounting blocks end and by pin and spacing bearing pin be fixed as can 90 degree launch entirety, the sidewall of the outer mounting blocks " u "-shaped opening side of spacing bearing pin correspondence position forms arcuation stopper slot, directly rotate a spike namely can launch to use, more existing Foldable support is compared has compact conformation, rigidity is strong, the advantages such as simple operation.

Detailed description of the invention
In order to make the technological means of the present invention, creation characteristic, reach purpose and effect is easy to understand, below in conjunction with being specifically illustrating, the present invention is expanded on further.
Referring to Fig. 1-3, sofa Foldable support, comprising: the back flap hinge 1 fixing with sofa body, back flap hinge 1 is made up of all " U "-shaped outer mounting blocks 11 in cross section and interior mounting blocks 12, the end accommodation of interior mounting blocks 12 is in the " u "-shaped opening of outer mounting blocks 11 end and be fixed as by pin 3 and spacing bearing pin 4 can the entirety of 90 degree expansion, installing hole I 113 is formed in the bottom of outer mounting blocks 11 " u "-shaped opening direction, installing hole I 113 is for fixing outer mounting blocks 11 with sofa body, the bottom of interior mounting blocks 12 " u "-shaped opening direction forms installing hole II；Installing hole II is for a fixing spike 2, concrete structure is: spike 2 one end is placed in interior mounting blocks 12 " u "-shaped opening, the side of a spike 2 is provided with the screwed hole suitable with installing hole II, a spike 2 is fixed after fastening through installing hole II with screwed hole by bolt with interior mounting blocks 12, the sidewall of the outer mounting blocks 11 " u "-shaped opening side of spacing bearing pin 4 correspondence position forms and moves the arcuation stopper slots 111 in 90 degree of expansion by outer mounting blocks 11 and interior mounting blocks 12 for spacing bearing pin 4 simultaneously, during expansion, towards side rotational support foot 2, spacing bearing pin 4 is mobile in arcuation stopper slot 111, the angle of outer mounting blocks 11 and interior mounting blocks 12 becomes larger until angle becomes 90 degree namely completes expansion.
nullAfter spike 2 is packed up or is launched，In order to ensure that it is packed up or launches rear stability，Further it is improved by，The two ends of arcuation stopper slot 111 form the access aperture 112 accessed for spacing bearing pin 4 respectively，Spacing bearing pin 4 is extended with diameter less than spacing bearing pin 4 and can the elongated end 42 of movement in the arcuation stopper slot 111 between access aperture 112 outside access aperture 112，After spike 2 is packed up or is launched，Spacing bearing pin 4 is in access aperture 112，Its movement in arcuation stopper slot 111 is limited，Spike 2 is retained as to be packed up or deployed condition，When spike 2 is packed up or launches，Spacing bearing pin 4 is promoted towards side，The elongated end 42 that spacing bearing pin 4 diameter is less falls in access aperture 112，Now spacing bearing pin 4 can do 90 degree of rotations thus completing folding or launching in arcuation stopper slot 111.
After propping up spike 2 expansion, in order to prevent the displacement of spacing bearing pin 4 from causing, a spike 2 is folded, it is provided with and the back-moving spring 5 of spacing bearing pin 4 coaxial arrangement in the space of interior mounting blocks 12 " u "-shaped opening restriction, particularly as follows: spacing bearing pin 4 circumference forms flange collar 41, back-moving spring 5 is arranged between the sidewall of flange collar 41 and interior mounting blocks 12, press spacing bearing pin 4, the elongated end 42 that spacing bearing pin 4 diameter is less falls in access aperture 112, now spacing bearing pin 4 can move a spike 90 degree rotation in arcuation stopper slot 111, after spacing bearing pin 4 completes rotation, its end falls in access aperture 112, under the effect of back-moving spring 5, it is outside that the elongated end 42 that spacing bearing pin 4 diameter is less is moved to access aperture 112, the now movement of spacing bearing pin 4 is limited.
For scratch base plate after preventing the spike 2 from launching, the earth terminal in a spike 2 is fixed with plastics rubber cushion 6.
The foregoing is only the preferred embodiment of the present invention; protection scope of the present invention is not limited in above-mentioned embodiment; every technical scheme belonging to the principle of the invention belongs to protection scope of the present invention; for a person skilled in the art; the some improvement carried out under the premise without departing from principles of the invention, these improvement also should be regarded as protection scope of the present invention.
