Embodiment
The present invention will be further described in detail below in conjunction with accompanying drawing.
New type of adjustable folded fastener member of the present invention can be regulated along with tie point, thereby guarantees the accurate connection between the link.Especially, adjustable folded fastener member of the present invention at link attachment hole as shown in Figure 3 and Figure 4.Attachment hole shown in the figure is different from traditional circular attachment hole, and it is a strip hole, and the two ends of this strip hole are isodiametric semicircle, and the length of its length direction is D1, and the length of width direction is D, and D1＞D.Adopt above-mentioned attachment hole be of value between the attachment hole of different links accurately relatively, thereby fundamentally guarantee normal mounting between the link.
Fig. 5 is the structural representation of a kind of new type of adjustable folded fastener member of the present utility model.As seen from the figure, this adjustable folded fastener member comprises a U type main body on the whole, and wherein this U type main body is integrated, and it comprises three parts, first sheet metal, second sheet metal, and the connecting plate that connects first sheet metal and second sheet metal.One strip hole is arranged on first sheet metal, and the two ends of this strip hole are isodiametric semicircle, and its attachment hole big or small and on the link is identical.There is a cylinder position with respect to strip hole on second sheet metal, and the diameter of this cylinder equates with the width of strip hole.Wherein, the part of cylinder correspondence is a hollow out on second sheet metal.When first sheet metal paralleled with second sheet metal, the center of cylinder was relative with the center of strip hole.
Usually, this adjustable folded fastener member adopts spring steel to make.Be processed with tapped hole in above-mentioned cylinder interior, be used for realizing that with bolt screw pair cooperates.The internal diameter of tapped hole is corresponding with the diameter of bolt.Usually, the inside diameter ranges of tapped hole is 4mm-20mm.
In addition, first sheet metal and second metal sheet surface are the smooth flat structure so that with link between firm the connection.When this adjustable folded fastener member was not worked, first sheet metal and second sheet metal were not parallel to each other, and second sheet metal tilts to the direction of first sheet metal; During work, this adjustable folded fastener member is clamped on the Assembly part, is parallel to each other between two sheet metals, and the distance between the two is the thickness of Assembly part, just the length of above-mentioned connecting plate.Usually, the length range of connecting plate is between 5mm-20mm.
Following mask body is introduced the using method of adjustable folded fastener member of the present invention.
When the attachment hole of Assembly part is processed intact, when not having error, as shown in Figure 6, at first adjustable folded fastener member 1 is clamped on the part 2, and the tapped hole profile of adjustable folded fastener member 1 projected in the attachment hole profile on the part 2 fully, simultaneously, also project in the attachment hole profile of part 3.Then, bolt 4 is passed the attachment hole of part 3 and part 2 respectively, and realize the mutual interlock of the screw thread that bolt 4 and tapped hole are interior, thereby realized that part 2 and part 3 directly are fastenedly connected.
Coarse when the attachment hole processing of Assembly part, when occurring than mistake, the advantage of adjustable folded fastener member of the present invention has just obtained embodiment.
When the attachment hole of part 3 exists than mistake on directions X, as shown in Figure 7, at first adjustable folded fastener member 1 is clamped on the part 2, make the tapped hole profile on it project to fully on the attachment hole profile of part 2, and with adjustable folded fastener member 1 and part 2 on the whole along the directions X adjustment, profile until tapped hole projects in the attachment hole profile of part 3 fully, then bolt 4 is passed the attachment hole of part 3 and part 2 respectively, and the mutual interlock of the screw thread in realization bolt 4 and the tapped hole, thereby make under coarse situation at part, realized that simply and easily part 2 and part 3 directly are fastenedly connected.
Similarly, when there is bigger error in part 2 on the Y direction, at first need adjustable folded fastener member 1 is clamped on the part 2, and adjust along the Y direction, make the profile of tapped hole can project to simultaneously in the attachment hole profile of part 2 and part 3 simultaneously, the last attachment hole that again bolt 4 is passed part 3 and part 2 respectively, and the mutual interlock of the screw thread in realization bolt 4 and the tapped hole, thus successfully realized being fastenedly connected between part 2 and the part 3.
Therefore, a kind of new type of adjustable folded fastener member of the present utility model is simple in structure, easy to use, using scope is wide, and greatly reduce the accuracy of manufacturing requirement of part with a plurality of attachment holes, and improved the assembling speed of part simultaneously greatly, shortened the manufacture cycle of product.
More than specific embodiment of the utility model is described in detail, but the utility model is not restricted to specific embodiment described above, it is just as example.To those skilled in the art, any equivalent modifications that this new type of adjustable folded fastener member is carried out and substituting also all among category of the present utility model.Therefore, not breaking away from impartial conversion and the modification of having done under the spirit and scope of the present utility model, all should be encompassed in the scope of the present utility model.
