The specific embodiment

See also Fig. 1, for buffering bracket 10 of the present invention launches scheme drawing, this buffering bracket 10 launches to be an integral type cardboard, and this cardboard is once the plane preformed board 100 of crossing stamping-out and backfin, and described buffering bracket 10 is formed by these plane preformed board 100 bendings.This preformed board 100 comprises a mainboard 110 and two two auxilliary plates 120 that are connected to these mainboard 110 relative both sides.

Described mainboard 110 comprises a rectangular backboard 112 and two risers 114.Described two auxilliary plates 120 and two risers 114 are connected on two groups of opposite side of described backboard 112.Both ends near described auxilliary plate 120 on described backboard 112 are formed with two hole clipping 112a that parallel with the line of backboard 112 with described auxilliary plate 120 respectively.

Middle part on described riser 114 is formed with a dual slope 114a, and this dual slope 114a parallels with the connection side of described backboard 112 with this riser 114.Be formed with on the described riser 114 two vertically run through described dual slope 114a and respectively with described backboard 112 on the draw-in groove 114b of two hole clipping 112a conllinear, described two draw-in groove 114b are parallel to each other and are symmetrically distributed in the both sides of described dual slope 114a.Described each riser 114 away from described backboard 112 and with a end margin that described backboard 112 parallels on convex with a boss 116, vertically extend two brace panels 118 respectively on the dual-side 116a of this boss 116 perpendicular to described riser 114, described riser 114 certain distances are protruded in the end of described each brace panel 118, be formed with the bayonet socket 118a that parallels with the draw-in groove 114b of the hole clipping 112a of described backboard 112 and riser 114 at described each brace panel 118 away from the end of described riser 114, the opening direction of the bayonet socket 118a of each brace panel 118 is identical.

Described two auxilliary plates 120 are connected on the relative both sides of backboard 112 between the described riser 114.Be formed with two space certain distances at the middle part of described each auxilliary plate 120 respectively and be parallel to described backboard 112 and the broken line 120a, the 120b that are somebody's turn to do the connection side of assisting plate 120.Be provided with in the end of described each auxilliary plate 120 two be parallel to each other and with two the otch 120cs of described backboard 112 with the connection side conllinear of riser 114.Form a buckle 122 that protrudes described auxilliary plate 120 certain distances between two otch 120c of described each auxilliary plate 120, the size of described buckle 122 on the connection side direction of described backboard 112 and described auxilliary plate 120 and described backboard 112 are measure-alike with connection side that should auxilliary plate 120, are convenient to described buckle 122 and can insert by described two risers 114 along backboard 112 relatively after the bending in the formed cavity.Described buckle 122 equals the distance between the connection side of the dual slope 114a of described riser 114 and riser 114 and described backboard 112 away from the distance between the end edge of the described backboard 112 broken line 120a adjacent thereto, with so that described buckle 122 on the riser 112 that after the bending its end edge is supported at described mainboard 110, has the high cavity volume of equal wall thereby make described auxilliary plate 120 and described riser 114 bending backs form one.Convex with a clamp 124 at described each buckle 122 away from described auxilliary plate 120 and the end that parallels with described broken line 120a, described clamp 124 in that this side up is measure-alike or be slightly less than described hole clipping 112a in the size that this side up, makes described clamp 124 can be fastened among the hole clipping 112a of described backboard 112 along the size of the direction that is parallel to described broken line 120a and described hole clipping 112a.

See also Fig. 2 to Fig. 5, during these buffering bracket 10 moulding, at first two risers 114 of described mainboard 110 are folded into the position perpendicular with described backboard 112 along described riser 114 is relative with backboard 112 connection sides respectively, and with described two risers 114 to the direction that deviates from mutually along the dual slope 114a at each riser 114 middle part bending twice, the draw-in groove 114b that is symmetrically formed on each riser 114 on described dual slope 114a both sides is overlapped.Then with two auxilliary plates 120 along connection side relative bend of described backboard 112 with described auxilliary plate 120, make on the riser 114 after described auxilliary plate 120 abuts against described bending.Then described two auxilliary plates 120 are bent relatively along separately broken line 120a, 120b respectively, the otch 120c of described auxilliary plate 120 engages with the draw-in groove 114a of described riser 114 is staggered, make the buckle 122 that is formed on this auxilliary plate 120 be contained in the space that surrounds by described riser 114, the end of described buckle 122 supports on the backboard 112 of described mainboard 110, and the clamp 124 that is formed on described buckle 122 ends is fastened among the hole clipping 112a on the described backboard 112.The backboard 112 of described mainboard 110, riser 114 and described auxilliary plate 120 are through forming a containing cavity 130 after the above-mentioned bending.At last, described buffering bracket 10 overturns, to be formed on the brace panel 118 of both sides of boss 116 of described each riser 114 along relative bending of connection side of this brace panel 118 with described boss 116, and two brace panels 118 of the same side that will be respectively formed at the boss 116 of two risers 114 snap together by described bayonet socket 118a, thereby make described riser 114 firm being fitted on the described backboard 112, on described backboard 112, form a buffer zone that is staggered to form by described brace panel 118 simultaneously.Thereby increase the steadiness and the buffering effect of described buffering bracket 10.

See also Fig. 6 and Fig. 7; during use; the buffering bracket 10 of two same structures of employing is set in the two ends of product 140 respectively; the two ends of described product 140 are contained in respectively in the accommodation space 130 of two buffering brackets 10; thereby described product 140 is held up; and described slow two buffering brackets 10 and the product 140 that is contained in therebetween together can be contained in the packing box 150, thereby product is protected.

This buffering bracket 10 adopts a whole cardboard creasing through stamping-out and backfin to form, and its manufacturing process is simple, and cost is low, environmental protection and pollution-free.

Be appreciated that, in order to make this buffering bracket 10 more efficient and convenient in manufacturing process, can with the position that hole clipping 112a fastens slick and sly transition corner be set at position and the described clamp 124 that described draw-in groove 114b and otch 120c fasten, thereby make described draw-in groove 114b more smooth and easy when engaging mutually with hole clipping 112a with otch 120c and clamp 124.

In addition, those skilled in the art also can do other variation in spirit of the present invention, as long as it does not depart from technique effect of the present invention, all should be included within the present invention's scope required for protection.
