Abstract

The invention discloses a fall-back stop mechanism for a super-large drop device. The super-large drop device includes a track with a "U" shape at the bottom and a product test vehicle installed on the track; the fall-back stop mechanism includes a A plurality of protruding teeth arranged at intervals in the upper and lower directions on the end section of the track and a test vehicle stop device installed on the product test vehicle, a lower stop is provided at the position below the lowermost protruding tooth on the end section of the track, and the end section of the track The position above the convex tooth at the uppermost end is provided with an upper stopper; the test car stopper includes a mounting seat, a falling back stopper, a rotating shaft, an unlocking hook plate, a locking slide plate, a reset dial, a tension spring and a rotating shaft torsion spring . The invention adopts a set of combination mechanism to realize the automatic process of one-way movement, fall-back stop, unlocking and unlocking and reset of the product test vehicle, and has the advantages of simple structure, convenience, safety and reliability.

Description

technical field [0001] The invention relates to an auxiliary mechanism for a drop device, in particular to a fall-back stop mechanism for a super-large drop device. Background technique [0002] The drop test device is an important scientific test device that uses the earth's gravity field to simulate mechanical impacts such as drops and impacts on products during transportation and use. It is an important indicator of reliability design to test the product's anti-drop ability through this device, and it provides an important research method for reasonable product packaging design. [0003] The drop test device generally consists of a lifting mechanism, a releasing mechanism, an attitude maintaining mechanism, a buffer mechanism, and control and testing equipment. During the operation of the drop test device, a large kinetic energy will be generated. Wherein, the buffer mechanism is used for buffering and absorbing the remaining kinetic energy of the attitude maintaining m...
