Abstract
The utility model discloses a safety belt end piece with a turnup circular hole. The safety belt end piece comprises an end piece body. The end piece body is provided with a free end and a fixed end, wherein the free end is connected with a safety belt woven belt, and the fixed end is connected with a car body through a fastening bolt. The free end is provided with the circular hole, the safety belt woven belt penetrates through the circular hole and is fastened, and the circular hole is of a turnup structure. In a stress state, deformation of the turnup structure is small, damage to the woven belt is slight, the degree of woven belt damage is reduced, and therefore car passengers can be protected.
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 when stressed for the protection of ribbon, 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.Yet the plastic gasket cost is higher, also increased the substrate installation procedure in production, after installing, long-term use easily comes off, and the protection effect is also not obvious.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of circular hole flange safety strap dististyle, and this dististyle can effectively protect belt-strap do not isolated and destroy, and can also reduce operation, reduces costs simultaneously.
A kind of circular hole flange safety strap dististyle described in the utility model, comprise the dististyle body, described dististyle body is divided into the free end be connected with belt-strap, and the fixed end be connected with vehicle body by binding bolt, described free end is provided with circular hole, belt-strap is through fastening from circular hole, and described circular hole is provided with turnup structure.
Described turnup structure comprises outer side flanging and interior side flanging, and wherein outer side flanging is R2.5 ± 0.1mm, and interior side flanging is R3.0 ± 0.1mm, and the height after flange is 6.0 ± 0.1mm.
The utility model adopts the circular hole dististyle to connect the flange structure; because be smoother flange, the transition of R angle; belt-strap has been played to the effect of a uniform stressed, dispersive stress effect; increasing gradually along with belt-strap application force tension force; the turnup structure distortion is very little; damage to ribbon is also very little, has played the degree that the protection ribbon destroys, and then has played the effect of protection automobile passenger.Compare the technology of originally with plastic gasket, protecting safe ribbon, former techniques intensity test is in the 20KN left and right, and the utility model can reach 24-25KN, and intensity has improved 20-25%; Former techniques intensity PPK is at 1.70-1.90 simultaneously, and PPK is at 2.0-2.4 for the utility model intensity, and stability is greatly improved.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the left view of Fig. 1,
Fig. 3 is the turnup structure of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, a kind of circular hole flange safety strap dististyle of the present utility model, comprise dististyle body 4, described dististyle body is divided into the free end be connected with belt-strap 1, and the fixed end be connected with vehicle body by binding bolt 3, described free end is provided with circular hole, and belt-strap 1 passes and fastens from circular hole, it is characterized in that, described circular hole is provided with turnup structure 2.
As Fig. 3, turnup structure 2 comprises outer side flanging and interior side flanging, and wherein outer side flanging is R2.5 ± 0.1mm, and interior side flanging is R3.0 ± 0.1mm, and the height after flange is 6.0 ± 0.1mm.
Principle of work: when binding bolt 3 and dististyle body 4 are connected on vehicle body that effect is stressed, belt-strap 1 is simultaneously stressed to stretch out, act on circular hole dististyle connection turnup structure 2 strength stress is arranged, due to turnup structure 2 because be smoother flange, the transition of R angle, belt-strap 1 has been played to a protection uniform stressed, the effect of dispersive stress effect, increasing gradually along with belt-strap 1 application force tension force, turnup structure 2 deformation rates are very little, damage to ribbon is also very little, played the degree that the protection ribbon destroys, and then played the effect of protection automobile passenger.
Forming method of the present utility model:
By twice machine-shaping; when wherein the dististyle of moulding stretching for the first time height is to 6.5mm ± 0.1mm; keep a stretch ratio; back-pressure moulding for the second time, compression dististyle height, to 6.0mm ± 0.1mm, increases dististyle local density; the compression material flow is to R2.5 ± 0.1mm and R3.0 ± 0.1mm; make the R angle more smooth smooth and easy, guarantee when dististyle R angle is stressed to can be uniformly dispersed drawing stress, play the effect of protection ribbon.
The concrete application approach of the utility model is a lot; the above is only 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.
