Externally-connected adjustable limiting device

Abstract

The invention relates to an externally-connected adjustable limiting device. The limiting device is characterized by comprising an upper limiting plate, an upper buffer block, a lower limiting plate and a lower buffer block which are arranged from top to bottom successively. The upper buffer block is connected with the lower buffer block through a steel sleeve and fixedly connected with the upper limiting plate, and a bolt is arranged in the steel sleeve and penetrates the steel sleeve and fastens the upper limiting plate, the upper buffer block and the lower buffer block through a nut and a spring washer. The diameter of a central hole of the lower limiting plate is larger than outer diameters of bosses of the buffer blocks. The upper buffer block is fixedly connected with the upper limiting plate through a pin. By means of the limiting device, the limiting problem during large spatial three-dimensional deformation produced by ordinary vibration isolation is solved, and the specific limiting requirements are met on the premise that the vibration isolation requirements are met.

Description

technical field [0001] The invention relates to an externally adjustable limiting device, in particular to a limiting device which is suitable for vibration isolation of elastic vibration isolation products and simultaneously limits three-dimensional deformation in space. Background technique [0002] With the vigorous development of modern industry, various fields such as ships, vehicles, aerospace equipment and engineering construction generally use vibration isolation (shock absorption) products such as wire rope vibration isolators, rubber type vibration isolators, spring shock absorbers and other products to achieve vibration isolation. (buffering) to achieve the purpose of normal and safe operation of the equipment. Due to the multi-directional displacement elastic deformation function of the vibration isolation product, although this dynamic deformation function is beneficial to the vibration isolation effect, it is not allowed in some special occasions, and it is nece...
