Abstract
The utility model discloses a double-flanging safety belt end sheet. The end sheet comprises an end sheet body. The end sheet body consists of a bottom plate and connecting parts, wherein the middle of the bottom plate is in contact with a vehicle body; both sides of the bottom plate are roughly vertical to the bottoms of the connecting parts; the bottom plate is provided with a bolt connecting hole; the connecting parts at both sides are respectively provided with mounting holes for a safety belt braid to pass through; flangings are arranged outside the mounting holes; and the flangings are round smooth flangings and R-angle flangings. According to the end sheet, not only can cost be reduced, but also the safety belt braid can be effectively protected from being cut and damaged.
Description
Technical field
The utility model relates to a kind of safety protection device used for vehicle, specifically a kind of middleware that belt-strap is connected with auto body by bolt.
Background technology
The safety strap dististyle is the middleware that belt-strap is connected with auto body, is not isolated damage for the protection of ribbon when stressed, to reach the purpose of protection occupant safety.Traditional safety strap dististyle is that the mounting hole edge (being dististyle body and belt-strap contact site) at the dististyle body arranges smooth plastic gasket, is connected the effect of playing the protection belt-strap with belt-strap by plastic gasket.The shortcoming of this structure is that the plastic gasket cost is high, and long-term use comes off easily after cooperating, the protection DeGrain.
The utility model content
Technical problem to be solved in the utility model provides a kind of double-turnup safety strap dististyle, and this dististyle not only can be saved cost, and can effectively protect belt-strap not isolated and destroy.
In order to realize above-mentioned technical purpose, the utility model provides a kind of double-turnup safety strap dististyle, comprise the dististyle body, described dististyle body is by the middle base plate that contacts with vehicle body, and the base plate both sides roughly form with the rectangular connecting portion in bottom, be provided with bolt connecting hole at base plate, the connecting portion in both sides is respectively equipped with the mounting hole that passes for belt-strap, and the described mounting hole outside is provided with flange.Described flange is smoother flange, the transition of R angle.
The R angle is R1.5-R2 mm, and outer side flanging R1 angle is R1.5-R3.5 mm, and transition R2 angle is R0.5-R1.5mm, and flange height is h1.80-2.00mm, and extending the degree of depth is the positive and negative 0.2mm of 7 mm.
The beneficial effects of the utility model: such as Fig. 3; after the dististyle body is connected on the vehicle body by binding bolt; when in use being subject to application force; the stressed F of belt-strap outwards stretches; can there be a strength stress in the stressed side of the mounting hole of belt-strap; because flange of the present utility model place is smoother flange; the transition of R angle; belt-strap has been played a protective effect; reach stressed even; the effect of dispersive stress effect; even the further increasing of belt-strap application force; the modification rate of dististyle is also very little, and is also very little to the damage of ribbon itself, and then played the effect of protection automobile passenger.In addition, the utility model has also saved plastic gasket, has saved cost.With the contrast test of prior art in, the ultimate strength of prior art is about 30KN, the utility model can reach 44-46.5KN, intensity has improved 25-30%; The Simultaneous Stabilization raising, prior art intensity PPK(PPK is used for calculation process ability or be process capability index in the control chart among the SPC, when referring to that the consideration process has deviation, the process performance of sampled data) about 1.75-1.88, PPK is at 2.2-2.6 for the utility model intensity, and stability improves greatly.

The specific embodiment
As shown in Figure 1, the utility model provides a kind of double-turnup safety strap dististyle, comprise the dististyle body, the dististyle body is by the middle base plate 1 that contacts with vehicle body, and base plate 1 both sides roughly form with the rectangular connecting portion in bottom 2, are provided with bolt connecting hole 3 at base plate 1, connect vehicle bodies by bolt 7, connecting portion 2 in both sides is respectively equipped with the mounting hole 5 that passes for belt-strap 4, and described mounting hole 5 outsides are provided with flange 6.
The preparation process of this double-turnup safety strap dististyle may further comprise the steps:
1) with the blank flat of 3mm on punch press once punching press form straight base plate and connecting portion shape, wherein form bolt connecting hole on the base plate, connecting portion forms the mounting hole that belt-strap passes;
2) adopt the shape draw punch (Fig. 4,5) corresponding with the mounting hole shape that the mounting hole edge is carried out the moulding first time and stretch, mounting hole edge absolute altitude reaches 5.9-6.1mm after stretching.Wherein the die drawn drift is of a size of: lower radius 1 ± 0.1mm, upper radius are 2.5 ± 0.1mm.
3) such as Fig. 2, for the second time back-pressure moulding, mounting hole edge absolute altitude reaches 4.5-5.5mm after the compression, mounting hole edge local density is increased, side flanging R angle is R1.5-R2 mm in after the compression, and outer side flanging R angle is R1.5-R3.5 mm, and transition R angle is R0.5-R1.5mm, flange height is 1.80-2.00mm, and extending the degree of depth is the positive and negative 0.2mm of 7 mm;
4) be bent to form the right angle between with both sides connecting portion and base plate on the angle bender.
The concrete application approach of the utility model is a lot; the above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
