Problems solved by technology
In the production process of the airbag, it is a necessary process to detect whether it leaks air. The existing detection method is generally to inflate it and place it in a container filled with water. If it leaks, many small bubbles will appear continuously. Moreover, after the inspection, the airbag needs to be dried. The operation steps are cumbersome, the manpower is required, and it is not smart enough.

Embodiment Construction
[0011] The present invention will be further described below in conjunction with the accompanying drawings.
[0012] Shown, a wide applicability airbag air tightness testing device, including a base 1, the two sides of the base 1 are fixed with baffles 2, and the base 1 is provided with two sliders that can move horizontally relative to it. 31, a spring 4 is arranged between the slider 31 and the baffle 2, at least one pressure sensor 31 is arranged on the opposite surfaces of the two sliders 31, and a pressure sensor 31 is arranged on the upper side of the base 1 for controlling the airbag. Inflatable air pump5.
[0013] After the airbag is inflated by the air pump, the pressure sensor is used to detect whether the elastic force of the compressed spring changes, so as to judge whether the airbag is qualified, simple and reliable, and not limited by the size of the airbag, and has wide applicability.
[0014] The top of one of the baffles 2 is provided with an indicator light...

The invention discloses an airbag gas tightness detection device with wide applicability; the airbag gas tightness detection device comprises a pedestal; stop plates are fixedly arranged on two sidesof the pedestal; the pedestal is provided with two slide blocks capable of horizontally moving with respect to the pedestal; a spring is arranged between the slide block and the stop plate; opposite surfaces of the two slide blocks are respectively provided with at least one pressure sensor; a gas pump used for filling air for the airbag is arranged above the pedestal; the gas pump can fill the airbag; the pressure sensor can detect whether the compressed spring has elastic force changes or not, thus determining whether the airbag is qualified or not; the airbag gas tightness detection deviceis simple and reliable, not limited by airbag dimensional sizes, and wide in applicability.
Description
technical field [0001] The invention relates to an air bag air tightness detection device with wide applicability, which belongs to the technical field of automatic detection equipment. Background technique [0002] An airbag is a volumetric object that can be stretched by utilizing the compressibility of air and the fluidity of water. In the production process of the airbag, it is a necessary process to detect whether it leaks air. The existing detection method is generally to inflate it and place it in a container filled with water. If it leaks, many small bubbles will appear continuously. Moreover, after the detection, the airbag needs to be dried. The operation steps are cumbersome, the manpower is required, and it is not smart enough. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a widely applicable air bag air tightness detection device. After the air bag is inflated by the air pump, the pressure sensor ...
