Repeatable cushioning device with locking function

Abstract

The invention relates to the technical field of buffer structures, in particular to a buffer device. The buffer device comprises a spring, a disc, a driving mechanism, an upper sleeve, a middle sleeveand a lower sleeve; the upper sleeve, the middle sleeve and the lower sleeve are disposed from top to bottom; the disc comprises s disc body and a plurality of reset bolts which are uniformly distributed along the disc body; the reset bolts can be inserted into tooth grooves; the multiple reset bolts are in one-to-one correspondence with multiple bolt return channels; the spring is disposed in the upper sleeve, one end of the spring is connected with the top of the upper sleeve, and the other end of the spring is connected with the disc; and the driving mechanism is fixed into the lower sleeve and is in transmission connection with the disc, and thus the disc is driven to rotate. The buffer device is exquisite in structure, capable of effectively absorbing the impact force to provide effective buffer, and reusable, all parts interact mechanically, the safety and reliability are achieved, and the sealing problem does not need to be worried. After the spring is compressed, the bottoms of inserting grooves clamp the bottoms of the reset bolts, and then the spring is prevented from immediately bouncing.

Description

Technical field [0001] The present invention relates to the technical field of buffer structures, in particular to a repeatable buffer device with a locking function. Background technique [0002] The legged lander will be impacted during the landing process, so it needs to be equipped with buffer devices. Commonly used buffer devices include aluminum honeycomb, metal cutting and other buffer methods, but these buffer devices cannot be reused; there are also hydraulic, oil and gas buffer methods, However, these buffer devices require a temperature control system and have high requirements for sealing, which increases the complexity and instability of the system. Summary of the invention [0003] The purpose of the present invention is to provide a repeatable buffer device with locking function to solve the above-mentioned problems. [0004] The present invention provides a repeatable buffer device with locking function, which includes a spring, a disc, a driving mechanism, and an u...
