The right end of the slide strip is provided with the horizontal chock strip which is vertical to the slide strip and has a rectangular section. 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
The present invention relates to a kind of experimental apparatus, particularly relate to a kind of non-shaking compound pendulum starting device.
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 in swing, produce twisting, 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.
Summary of the invention
The present invention provides a kind of non-shaking compound pendulum starting device that can eliminate the initial shake of physical pendulum for solving the deficiency of prior art.
The scheme that solves technical matters of the present invention is: non-shaking compound pendulum starting device is made up 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 said 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 said 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 move 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, the shake that has no produces, and 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.
