Abstract

The invention discloses a novel adjusting air cylinder which comprises a hollow cylinder body (2). The novel adjusting air cylinder is characterized in that a first boss (6) with a center hole (4) is arranged on the inner wall of the cylinder body (2); an inner cavity of the cylinder body (2) is divided into a first chamber (8) and a second chamber (10) by the first boss (6); the first chamber (8) and the second chamber (10) are communicated through the center hole (4); a piston (12) in sliding fit with the first chamber (8) and a piston rod (14) fixed to the piston (12) are arranged in the first chamber (8); a valve element (16), an exhaust hole (18) and an annular check ring (20) are arranged in the second chamber (10). The hollow cylinder body (2) is provided with the two chambers, and the motion of the air cylinder is divided into two relatively-independent parts; in this way, on the one hand, the stroke of the air cylinder can be shortened; on the other hand, fast exhaust can be achieved, and the lifting height and lifting frequency of the air cylinder are greatly improved.

Description

technical field [0001] The invention relates to a novel regulating cylinder. Background technique [0002] The crash test machine is used in the laboratory to simulate the ability of the product to withstand impact damage in actual use, so as to evaluate the adaptability of the product to the impact environment, and then optimize the structural strength of the product through the test data to correctly evaluate the impact resistance of the product. Can effectively improve the reliability of product use. [0003] Crash testing machines in the prior art usually use mechanical mechanisms such as cams to realize lifting. This method has relatively low energy, small lifting height, and low lifting frequency. [0004] Certainly, in the prior art, also have to adopt air cylinder as lifting mechanism, but limited by the stroke of air cylinder, its effect is not very ideal either. Contents of the invention [0005] The technical problem to be solved by the present invention is to...
