The power-assisted air bag 109 is made of flexible rubber, when the hanging ring 7 is unhooked and the power-assisted spring 104 is inflated, the power-assisted air bag 109 is in a bulge stretching state, after the power-off temperature is reduced, the power-assisted air bag 109 is in a shrinkage state, after the hanging ring 7 is hung again, the power-assisted air bag 109 is in a bulge balance state, the temperature in the installation cavity 2 is changed into the bulge stretching state again along with the rising of the temperature, the power-assisted spring 104 is made of hard rubber, and the thrust of the power-assisted spring 104 is enough to drive the linkage wheel 5 and the regulating brake 3 to rotate.
Through the volume of the design helping hand gasbag 109, let helping hand gasbag 109 normal operating be in not by tensile state always, alleviate its working fatigue degree, increase of service life, after the temperature rises to a certain extent, helping hand gasbag 109 begins to hold the power, gets into the state of readiness, if the temperature is replied later, helping hand gasbag 109 also resumes balanced state again, if because of high temperature release, helping hand gasbag 109 can in time provide power.
Further:
the opening of the outer side of the air flue 105 is fixedly connected with a mounting net rack 11, the inner side of the mounting net rack 11 is fixedly connected with a regulating and controlling piston 12, and the right end of the regulating and controlling piston 12 is provided with a balance air hole 13;
the installation net frame 11 wraps the outer side of the power assisting air bag 109, and the opening area of the balance air hole 13 is smaller than that of the power assisting air hole 108.
The regulating piston 12 extends into the power-assisted air bag 109, and the inner cavity of the regulating piston 12 is communicated with the power-assisted air bag 109 through the balance air hole 13; the force required to regulate the sliding of the piston 12 is less than the force required to stretch the surface of the material as the booster bladder 109 expands.
By connecting the regulating piston 12 on the booster air bag 109, when the temperature in the closing state rises normally, the expanded gas can enter the regulating piston 12 through the balance air hole 13 at first, the regulating range is enlarged, so that the booster air bag 109 cannot accumulate force in advance, the working fatigue degree of the booster air bag is weakened, and the service life is prolonged;
by designing the opening area of the balance air hole 13 to be smaller than that of the power-assisted air hole 108, when the temperature is increased suddenly, more air flows from the power-assisted air hole 108 to the power-assisted spring 104, so that sufficient power is ensured.
The above description is only of the preferred embodiments of the present invention; the scope of the invention is not limited in this respect. Any person skilled in the art, within the technical scope of the present disclosure, may apply to the present invention, and the technical solution and the improvement thereof are all covered by the protection scope of the present invention.
