Abstract

The utility model discloses a tightness regulating button of an automobile safety belt, which can be used for preventing a safety belt form returning and is composed of a box body and a non-return mechanism in an internal cavity; the safety belt penetrates through a groove-shaped inlet and a groove-shaped outlet on both ends of the box body. The utility model is arranged on an outlet of the automobile safety belt or nearby a safety fastener; after a passenger fastens the safety belt, the belt with the tightness which is properly regulated does not return because of the fastening action of a ratchet wheel which can only make unidirectional rotation and is in the internal cavity of the regulating button. The utility model reduces human body's bound feeling when the user ties the safety belt, which is helpful for the passengers to use the safety belt happily and can relieve the casualty degree which is caused by automobile accident. When the tightness needs to be regulated, a press button on the inlet of the safety belt can be pressed; the regulating button can be easily slid on the safety belt; when the press button is drawn off, the safety belt is fastened by the ratchet wheel because of the fact that the ratchet wheel is lifted by a reset spring so that the safety belt can not return. The utility model can be matched with the existing safety belt for use.

Description

Car belt degree of tightness adjusting button

Technical field

The utility model relates to the car accessories field, especially refers to the tightness of safety strap is regulated and can be stoped the car belt degree of tightness adjusting button of belt retraction.

Background technology

In China developed area, automobile has become the main vehicle of people's trip.Existing traffic law all requires safety strap is set on automobile, and wears Safety Belt when stipulating driver and conductor's driving and riding car.The design of car belt is also very ingenious really, and it when it is slowly pulled out in hiding box, can not withheld in use.And when automobile emergency brake or bump, because of inertia makes its speed of pulling out and stressed increase, belt will be blocked by the in-to-in buckle.Therefore the effect of safety strap is conspicuous, when it meets accident at automobile, the driver and conductor can not thrown away in car, thereby can alleviate injures and deaths.But because China is a developing country, the revision with traffic law of increasing rapidly of automobile also is in recent years a thing, people are to the also little custom of fastening the safety belt, so just the driver who has is with once when dealing with that traffic constable is checked just, then seldom be usefulness at ordinary times.The another one odjective cause then is that safety strap has the constraint sense to driver and conductor's health really, because in the continuous vibration of safety strap when running car, its cam mechanism can contract belt more tight.Can not bounce back inward after having no idea to make belt to fasten, make the driver and conductor after fastening belt, remain the suitable device of degree of tightness? the applicant is through in a few years trial production, design successfully car belt degree of tightness adjusting button, solved the uncomfortable problem that constraint brings to the person that belt retraction produced preferably.

The utility model content

Technical problem to be solved in the utility model is: provide a kind of car belt degree of tightness adjusting button that stops the belt retraction to society, can remain the original tightness of belt in use, alleviate constraint sense to human body, thereby the driver and conductor is willing to is usefulness, alleviates the injures and deaths degree when meeting accident.

The technical scheme of the utility model technical solution problem is: on existing car belt, pierce into one can be free movable adjusting button, after safety strap is fastened, adjusting button is arranged near the exit or safety catch of belt, be several places of belt stress points, belt can not be bounced back, thereby can keep original tightness from start to finish, and the normal functions of use of safety strap is had no effect.The utility model is made up of box body and non-return mechanism two parts, comprises loam cake, housing, button, ratchet, bearing pin, retracing spring and support spring.Described box body is flat capsule, and two ends are provided with the import and export that just allow belt pass through, and is provided with ratchet, pivot pin, retracing spring and support spring in the housing inner chamber.Described button is arranged on an end exit, and its effect is the gap of regulating between ratchet and the belt, and it can be slided on belt or block, and reaches the purpose of adjusting.Described ratchet is cylindric, and the center is fixed on the both sides of box body by bearing pin, and the skewed slot angled with axis is carved with on the surface of cylinder.

The utility model can be arranged near belt exit or the safety catch, and allowing belt pass from the centre can use.It is because of can stoping belt retraction, but unaffected and allow the user regulate freely when extracting out, therefore will be for being subjected to driver and conductor's extensive welcome.

The specific embodiment

As depicted in figs. 1 and 2, the utility model is made up of non-return mechanism two parts in box body and the inner chamber.The main portion of box body is that the capsule that is flat is a housing 1, has been screwed a loam cake 2 above, and two ends are provided with the import and export that can allow safety strap to pass through.Be equipped with the bearing pin 5 of ratchet 4, retracing spring 6, support spring 7 and fixed ratchet wheel 4 in its inner chamber.The two ends frame of bearing pin 5 is on the skewed slot of the two side of housing 1.Ratchet 4 is cylindric, the bevelled groove is carved with on the surface, form helical teeth between adjacent two grooves, its crown is extracted direction out towards belt during installation, therefore crown can catch belt not allow its retraction when belt bounces back, simultaneously the axis of groove and ratchet 4 in an angle, its effect is to make belt progressively increased by resistance when bouncing back.Simultaneously owing to inserted a support spring 7 in the skewed slot, make the ratchet 4 in the ordinary course of things can only be clockwise, can not reverse, thereby reach the purpose of " non-return ".

Regulate when using, press the button 3, compressing ratchet 4, the skewed slot 8 of the bearing pin 5 of ratchet 4 on housing 1 two side is to lower slider, make the gap increase of ratchet 4 and bayonet socket, this moment, adjusting button can be free movable on belt, and adjusting button is moved on to required place, loosen button 3, because ratchet 4 is withstood in retracing spring 6 effects, the bearing pin 5 that makes ratchet 4 two ends is along skewed slot 8 upward movements, ratchet 4 is pushed down belt, and adjusting button is fixed on the correct position of belt.
