Embodiment
Below in conjunction with embodiment, the utility model is elaborated.Wherein identical component represent with identical reference character.It should be noted that, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in accompanying drawing, and word " interior " and " outward " refer to respectively the direction towards or away from specific features geometrical center.
Base and nut structure schematic diagram in the special-shaped fastening piece that Fig. 1 provides for the utility model embodiment, bolt structure schematic diagram in the special-shaped fastening piece that Fig. 2 provides for the utility model embodiment, Fig. 3 is the plan view after double-screw bolt and nut assembling, Fig. 4 is the plan view after double-screw bolt and nut assembling, and Fig. 5 is the main sectional view after double-screw bolt and nut assembling.
As shown in Figures 1 to 5, the utility model embodiment provides a kind of special-shaped fastening piece, and comprising base 1 be fixed on the nut 2 on base 1, this abnormity fastening piece also comprises double-screw bolt 3.Base 1 is fixed on the first fastener, and nut 2 coordinates the first fastener and the second fastener are linked together with double-screw bolt 3.
It is example that the present embodiment be take the fastening of triangular window of automobile back door, and above-mentioned the first fastener is quarter window, and the second fastener is glass guide-rail assembly.It will be appreciated by persons skilled in the art that special-shaped fastening piece that the present embodiment provides is not limited in is applied on triangular window of automobile back door, is also applicable to the fastening of other parts.
First base 1 is positioned on quarter window to the location that can realize base and quarter window by the first circular positioning hole 11 is set on base 1.On quarter window, be provided with locating stud, by positioning locating stud and the first coordinating of positioning hole 11, then base 1 is injection-moulded on quarter window, like this when follow-up and glass guide-rail support are installed, after the mounting hole that double-screw bolt 3 is passed on glass guide-rail assembly, be driven in nut 2, thereby realize being fastenedly connected of quarter window and glass guide-rail assembly.
At nut 2 and floor installation in the working process on quarter window, by first two the first positioning holes 11 on base 1 being located with the locating stud on quarter window, then the mode of carrying out injection moulding can avoid because of the technology characteristics of quarter window cannot accurately locate and quarter window profile positioning precision poor cause and glass guide-rail assembly between matching error and gap.
Fig. 6 is the schematic diagram of laterally cutting open along base, and preferably, nut 2 is fixedly connected with by spline 4 with base 1, as shown in Figure 6.Particularly, offer the hole with internal spline on base 1, the part that nut 2 is inserted in this hole is provided with external splines.It will be appreciated by persons skilled in the art that between nut 2 and base 1 and can also be connected by modes such as welding, but the mode of the connection of welding is non-dismountable.By spline joint, when guaranteeing nut steadiness, can make again the dismounting of nut become possibility, be convenient to maintenance and change.
On the basis of above-described embodiment, preferably, in the both sides of base 1, be relatively set with semicircular the second positioning hole 12.The second positioning hole 12 can play the effect of location in processing base 1, thereby can process accurately the position of the first positioning hole 11 and spline 4.
Further, above-mentioned base 1 is cold-reduced sheet, by techniques such as punching presses, forms.The material of nut 2 is cold-heading steel, and nut 2 forms through techniques such as cold-heading, boring, tapping and cuttings.Double-screw bolt 3 utilizes pole steel to form through techniques such as cutting, cold-heading, extruding, rolling, bore hole and tapping.Can determine according to the size of fastener the size of base 1, nut 2 and double-screw bolt 3.In the present embodiment, the length L of base 1 is 20-30mm, and width W is 9-15mm.The outside dimension of nut 2 is 4-10mm, and height h1 is 5-15mm.The Major Diam of double-screw bolt 3 is 3-8mm, and the height h2 of double-screw bolt is 5-15mm.
The special-shaped fastening piece that the utility model embodiment provides, tool has the following advantages:
1, realized because of technology characteristics be difficult to location part and the accurate location of part profile, the impact of having avoided matching error and having caused.The abnormity nut being positioned in advance on the first fastener is injected on the first fastener, then, by being used in conjunction with of nut and double-screw bolt, the first fastener accurately can be positioned on the second fastener.Thereby avoided fastener because part process feature cannot accurately be located, poor the causing with periphery part of part profile positioning precision exists matching error, the other influences of also having avoided the generation due to gap and offset to cause.
2, realize being fastenedly connected between fastener, can solve because of installing space narrow and smallly, standard series does not have the problem of applicable fastening piece.
Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technological scheme that still can record aforementioned each embodiment is modified, or part technical characteristics is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the scope of each embodiment's technological scheme of the utility model.
