Abstract
The utility model relates to a laboratory instrument, in particular to a compound pendulum zero-jitter generator, which comprises a knob, a fixing clamp, a sliding groove upper clamp, a stop block, asliding groove lower clamp, a support frame, a handle, a rotating wheel, a rotating handle, a slide bar, a retaining bar and a clamping ring. The fixing clamp with a F-shaped lateral surface is arranged at the upper end of the support frame; the horizontal retaining bar with a rectangular section vertical to the slide bar is arranged at the right end of the slide bar; threads are arranged in the position where the rotating handle is positioned between the sliding groove upper clamp and the sliding groove lower clamp; the outer end of the rotating handle and the rotating wheel are concentric and are integrated into a whole; and a handle which is integrated with the rotating wheel into a whole is arranged on the edge of the rotating wheel. The utility model can ensure that a swing link is not twisted during the swinging, thereby avoiding the experimental error caused by hand shaking and improving the accuracy of experimental results.
Description
Technical field
The utility model relates to a kind of experimental apparatus, particularly relates to a kind of physical pendulum zero jitter generator.
Background technology
In the experimentation that utilizes physical pendulum check weighing power acceleration, loose one's grip again after need the position that moves to certain altitude being revolved in the lower end of physical pendulum fork with hand.Owing to discharging fork in a flash, people's hand is easy to produce slight shake, and this can make fork produce twisting in swing, and such twisting can consume certain kinetic energy, the hunting period that this can influence physical pendulum undoubtedly, further increase the error amount of measurement result.
The utility model content
The utility model provides a kind of physical pendulum zero jitter generator that can eliminate the initial shake of physical pendulum for solving the deficiencies in the prior art.
The scheme that solves the utility model technical matters is: physical pendulum zero jitter generator is made of folder, support, handle, runner, turning handle, draw runner, blend stop and snap ring under folder, block, the chute on knob, geometrical clamp, the chute.The upper end of its medium-height trestle is that the side is the geometrical clamp of F shape, and the lower end of support is folder and the following chute that constitutes that presss from both sides of chute on the chute that is parallel to each other.The upper surface of geometrical clamp has a tapped through hole, and knob is in the described tapped through hole.Draw runner is a strip, draw runner is on the chute folder and chute down between the folder, draw runner be positioned on the chute folder and chute down the position of the left and right side of folder respectively have one with draw runner be holistic block, the side that presss from both sides under folder and the chute on two blocks and the chute is in active relationship.It is the blend stop of rectangle that the right-hand member of draw runner has a cross section level, vertical with draw runner.Support is on the chute folder and chute has a through hole in the position between the folder down, and there is the tapped through hole that communicates with described through hole on the surface of block.Turning handle runs through the tapped through hole of block and the through hole of support simultaneously.Turning handle has screw thread in the part between the folder under folder and the chute on the chute.Be positioned on the turning handle at two ends of through hole of support and be with a snap ring respectively, two snap rings become the stationary fit relation, are in active relationship with support with turning handle.The outer end of turning handle and runner concentric and as a whole, having on the edge of runner with runner is the handle of one.
During installation, geometrical clamp is stuck in the edge of desktop, and tightens knob, support promptly is fixed, and the lower end with the physical pendulum fork places on the blend stop then.When beginning to test, hold the counterclockwise uniform rotation of handle, under the effect of the screw thread of turning handle, the longitudinal direction that draw runner presss from both sides on geometrical clamp and the chute is to moving at a distance, and blend stop is at the uniform velocity mobile thereupon, when blend stop leaves physical pendulum fork lower end, and the swing beginning.
Adopt such scheme, can reach following effect:
Because blend stop leaves the fork lower end in the process of uniform motion, without any shake produce, this has just guaranteed that fork does not produce twisting in the process of swing, trembles the experimental error that causes with regard to having avoided because of hand like this, has improved the accuracy of experimental result.
