Gas spring with adjustable stroke

Abstract

The invention relates to the technical field of air springs, in particular to a stroke-adjustable air spring. The stroke-adjustable air spring comprises a piston rod, a pressure pipe and a piston assembly. The pressure pipe is provided with a piston cavity. The piston assembly is arranged in the piston cavity. An inner cavity is formed in the piston rod. A through hole communicated with the inner cavity is formed in the piston assembly. An adjustment lever is arranged in the inner cavity in a sliding manner. A base is arranged at the bottom end of the pressure pipe. An inner pipe is arranged in the piston cavity. The adjustment lever passes through the inner pipe and is in threaded connection with the base. A lower connector is arranged on the base. A mounting groove is formed in the lower connector. The base is positioned in the mounting groove. A knob is arranged between the mounting groove and the base. A clamping strip is arranged on the knob. A clamping groove matched with the clamping strip is formed in the end part at the lower end of the adjustment lever. The knob is rotated, and through the transmission of the clamping strip on the knob and the clamping groove in the adjustment lever, the adjustment lever is driven to rotate relative to the base, the lifting of the adjustment lever in the inner cavity is realized, the stroke of the piston rod is adjusted, the adjusting is convenient and reliable, and requirements to different strokes on different application occasions can be met.

Description

technical field [0001] The invention relates to the technical field of gas springs, in particular to a gas spring with adjustable stroke. Background technique [0002] Since the gas spring has a relatively close to ideal quadratic curve elastic change characteristic, it has been widely used in many industries such as the automobile industry, printing machinery, medical equipment, office equipment, furniture manufacturing, industrial machinery, aerospace, and locomotive manufacturing. Some gas springs generally have a single stroke, which makes them unsuitable for many applications. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to solve the problem that the gas spring in the prior art generally has a relatively single stroke, which leads to the problem that it cannot be used in many occasions, a gas spring with an adjustable stroke is now provided. [0004] The technical solution adopted by the present invention...
