Problems solved by technology

Because at the moment of releasing the pendulum, the human hand is prone to slight shaking, which will cause the pendulum to twist while swinging. Such twisting will consume a certain amount of kinetic energy, which will undoubtedly affect the swing of the compound pendulum. period, further increasing the error value of the measurement result

Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0011] The non-shaking compound pendulum starting instrument consists of knob 1, fixed clip 2, chute upper clip 3, stopper 4, chute lower clip 5, bracket 6, handle 7, runner 8, rotating handle 9, slide bar 10, stop Bar 11 and snap ring 12 constitute. Wherein the upper end of support 6 is the fixed clamp 2 that side is F shape, and the lower end of support 6 is the chute that clip 3 and chute lower clip 5 that are parallel to each other constitute the chute. The upper surface of the fixing clip 2 has a threaded through hole, and the knob 1 is located in the threaded through hole. The slide bar 10 is elongated, and the slide bar 10 is located between the upper clamp 3 and the lower clamp 5 of the chute, and the slide bar 10 is located on the left and right sides of the upper clamp 3 and the lower clamp 5 of the chute Each one has a block 4 which is inte...

Abstract

The invention relates to an experimental instrument, in particular to a non-shaking compound pendulum starting device. The non-shaking compound pendulum starting device comprises a knob, a fixing clip, a slide way upper clip, a chock block, a slide way lower clip, a bracket, a handle, a rotating wheel, a rotating handle, a slide strip, a chock strip and snap rings. The upper end of the bracket isprovided with the fixing clip with the side face in an F shape. The right end of the slide strip is provided with the horizontal chock strip which is vertical to the slide strip and has a rectangularsection. A part of the rotating handle positioned between the slide way upper clip and the slide way lower clip is provided with screw threads. The outer end of the rotating handle and the rotating wheel are coaxial and are formed into a whole, and the edge of the rotating wheel is provided with the handle integrated with the rotating wheel into a whole. In the invention, a swing rod can be ensured not to twist in the process of swinging, the experimental error caused by tremor is avoided, and the accuracy of the experimental results is enhanced.

Description

technical field [0001] The invention relates to an experimental instrument, in particular to a non-shaking compound pendulum initiation instrument. Background technique [0002] In the experiment process of using the compound pendulum to measure the acceleration of gravity, it is necessary to rotate the lower end of the compound pendulum bar to a certain height by hand and then let go. Because at the moment of releasing the pendulum, the human hand is prone to slight shaking, which will cause the pendulum to twist while swinging. Such twisting will consume a certain amount of kinetic energy, which will undoubtedly affect the swing of the compound pendulum. period, further increasing the error value of the measurement result. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the invention provides a shake-free compound pendulum initiation instrument which can eliminate the initial jitter of the compound pendulum. [0004] The solution...
