Background technology

Car belt is the health for fixing driver and conductor, to reduce crash injury rate and mortality, arranges.The speed of modern automobile is very fast, once bump, human body under effect of inertia in Che Nei and vehicle body strikes, when serious, may fly out outside window, therefore, public security department requires chaufeur and front-seat passenger to use of seat belts, so that while there is traffic accident, safety strap plays the effect of buffering to human body, prevent secondary injury.

Generally the car belt of application has pre-tightening apparatus now, produces some strength impact once collision happens, and pre-tightening apparatus tightens up safety strap, and safety strap will, always in tightening up state, firmly be fixed human body on the seat.But this car belt Shortcomings: when bumping, can the output very large pulling force of safety strap is with the motion of restriction human body, but this pulling force can hurt human body when excessive, has potential safety hazard.

Summary of the invention

In order to overcome above-mentioned defect, the utility model provides a kind of automobile safety belt buckle, can be directly installed in existing car belt system, prevents that human body from being pulled by safety strap when bumping.

The utility model for the technical scheme that solves its technical matters and adopt is: a kind of automobile safety belt buckle, comprise snap close female and snap close male, the lower end of described snap close female is inserted in the upper end of described snap close male, and the lower end of described snap close male is inserted in automobile safety belt buckle female; The upper end of described snap close female is provided with the insert port of planting for automobile safety belt buckle male, this insert port can, by the automobile safety belt buckle male locking of inserting in it, also be provided with the unlock button that the lock-out state for this belt buckle male being locked in to insert port carries out release on the upper surface of described snap close female; Described snap close female inside is provided with spiral spring, and on this spiral spring, volume has one section of safety belt, and described snap close male inside is provided with coupling bar, and one end of described safety belt is fixed on spiral spring and its other end is fixed on described coupling bar; Described spiral spring has tightening force, by the described insurance roll coil of strip on described spiral spring and tighten up between described spiral spring and described coupling bar.

As further improvement of the utility model, the lower end of described snap close male is provided with for being inserted in the plate in automobile safety belt buckle female.

The beneficial effects of the utility model are: this automobile safety belt buckle when human body under tension is excessive by discharge a small amount of gap between safety strap and human body, prevent that human body from being pulled by safety strap, and can be directly installed in existing car belt system, easy to use, applied range.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model cross-sectional view.

By reference to the accompanying drawings, make the following instructions:

1---snap close female 2---insert port

3---unlock button 4---snap close male

5---plate 6---spiral spring

7---safety belt 8---coupling bar

The specific embodiment

By reference to the accompanying drawings; the utility model is elaborated; but protection domain of the present utility model is not limited to following embodiment, the equivalence of in every case being done with the utility model claim and description changes and modifies, within all still belonging to the utility model patent covering scope.

As shown in Figure 1 and Figure 2, a kind of automobile safety belt buckle, there is snap close female 1, snap close female 1 upper end is provided with insert port 2, adjacent with insert port 2 have a unlock button 3, automobile safety belt buckle male is inserted in snap close female 1 and is carried out locking by insert port 2, after locking, by unlock button 3, can carry out release.

There is snap close male 4 snap close female 1 lower end, and there is plate 5 snap close male 4 lower ends, and snap close male 4 is fixed in automobile safety belt buckle female by plate 5.

There is spiral spring 6 snap close female 1 inside, and on spiral spring 6, volume has one section of safety belt 7, and there is coupling bar 8 snap close male 4 inside, connects the other end of safety belt 7.

When automobile front is subject to colliding pulling force that safety strap sends human body and exceedes setting value, spiral spring 6 deforms gradually, volume safety belt 7 is thereon discharged, snap close female 1 is Fen Li gradually with snap close male 4, between safety strap and human body, constantly discharge gap, reduce the pulling force of safety strap to human body, prevent that human body from being pulled by safety strap.

Along with force of inertia constantly reduces, pulling force human body being sent when safety strap is reduced to when to setting value, and the spiral spring 6 of distortion resets gradually, and the safety belt discharging 7 is regained.
