Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0017] The embodiments of the present invention disclose an airbag detection device, which can quickly detect rubber airbags and can meet the technical requirements for rubber airbag detection. The present invention fills the domestic blank of no such product detection device, solves the problems of expensive and complex structures of foreign detection devices. The device has a simple structure and low manufacturing cost, and can meet the technical requirements for rubber airbag detection.

[0018] An airbag detection device includes a base 1, a movable plate 2, a fixed column 3 and a pressure plate 4, wherein the base 1 is provided with an air storage groove 5 with an opening facing upward, and the fixed column 3 is vertically arranged at the center of the base 1; the movable plate 2 is provided with an air outlet hole 6, and the movable plate 2 is slidably arranged on the fixed column 3, and an air storage cavity is formed between the movable plate 2 and the base 1; the pressure plate 4 is arranged above the movable plate 2, and the pressure plate 4 is fixed to the fixed column 3 by a limiter.

[0019] Preferably, in the above-mentioned airbag detection device, a spring 7 is arranged in the air storage chamber, the top end of the spring 7 is connected to the bottom surface of the movable plate 2, and the bottom end of the spring 7 is connected to the bottom surface of the air storage tank 5 on the base 1. After completing the test, loosening the limit piece can facilitate the separation of the movable plate 2 and the base 1.

[0020] Preferably, in the above-mentioned airbag detection device, the limiting member is a nut 8 , and the fixing column 3 is provided with an external thread matching the nut 8 . The nut 8 is screwed onto the external thread of the fixing column 3 to limit the pressure plate 4 .

[0021] Preferably, in the above-mentioned airbag detection device, an air inlet hole 9 communicating with the air storage cavity is provided on the side of the base 1 .
