Abstract
The utility model relates to a suspension type recoil movement tester that is a physical experiment teaching aid or learning tool. According to the tester, a bucket is suspended by a suspension fiber; a flow is sprayed from a bending pipe spiral arm to push the bucket to rotate; and a water control valve is controlled by a stay wire and thus the bending pipe spiral arm is controlled to jet the flow, so that the recoil rotation of the bucket is realized. The provided tester has the advantages of simple structure, low cost, easy operation, high experiment success rate, visual experiment phenomenon and high visibility.
Description
Technical field
The utility model relates to a kind of teaching aid or learning aid suspension-wire type recoil tester, especially utilizes suspension hanging well-bucket, promotes the suspension-wire type recoil tester of well-bucket rotation from spiral arm jet water course.
Background technology
At present, in regular senior secondary school's curricular standard experiment textbook physics teaching material, the lecture experiment instrument kind of recoil is many, and learning aid is little.Instrument is numbered 2167 recoil demonstration device, utilizes the water of rotation to leak recoil, and friction ratio is larger; Recoil trolley for demonstrating is made up of metal cylinder, rubber stopper, dolly, aluminium cup etc., complex structure, and experiment is dangerous large.Suspension-wire type recoil tester utilizes suspension hanging well-bucket can reduce friction, modern design, and experimental phenomena is directly perceived, safe to use, can excite student's curiosity, cultivates student's innovation ability.
Summary of the invention
The utility model provides one to utilize suspension hanging well-bucket, promote well-bucket rotation from bend pipe spiral arm jet water course, utilize bracing wire control water control valve, control bend pipe spiral arm jet water course, realize well-bucket back-flushing rotary, simple in structure, easy operating, Physical Experiment teaching aid or learning aid--the suspension-wire type recoil tester that visibility is high.
The utility model solves the technical scheme that its technical matters adopts: suspension-wire type recoil tester is by the base with horizontal shore, suspension, well-bucket and can form by floating water control valve, well-bucket is with the bend pipe spiral arm of two energy jet water courses, promote well-bucket back-flushing rotary from bend pipe spiral arm jet water course, utilize bracing wire promote can be floating water control valve, control bend pipe spiral arm and when start jet water course and promote well-bucket back-flushing rotary; Utilize suspension hanging well-bucket can reduce friction, Enhancement test effect.
The beneficial effects of the utility model are: suspension-wire type recoil tester utilizes suspension hanging to reduce friction by well-bucket, experimental phenomena is directly perceived, safe to use, with low cost, easy operating, experiment success rate is high, and visibility is large, utilizes suspension-wire type recoil tester can strengthen student's perceptual knowledge, can excite student's curiosity and aspiration to knowledge, cultivate student's innovation ability.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is suspension-wire type recoil tester one-piece construction figure.
In Fig. 1,101 is base, and 102 is horizontal shore, and 103 is suspension, and 104 is well-bucket, and 105 is bend pipe spiral arm, 106 be can be floating water control valve, 107 is basin.
Embodiment
Suspension-wire type recoil tester base adopts the melamine facing fiberboard that thickness is 16MM, the long 30CM of bottom panel, wide 20CM, the long 60CM of horizontal shore vertical rod, xsect is the lumps of wood of length of side 3CM, the long 15CM of horizontal hack lever, xsect is the batten of 3CM × 1.5CM, and horizontal shore vertical rod is screwed on base; Well-bucket is the circular transparent beverage bottle that removes the end, the high 20CM of well-bucket, and the long 30CM of suspension, two each long 6CM of bend pipe spiral arm, draw from the punching of Beverage Bottle Cap symmetria bilateralis, are glued; Can floating water control valve select the gel ball of hollow, with fine rule bolt jail, fine rule length is suitable, lies in well-bucket edge, is convenient to lift; Before the water filling of suspension-wire type recoil tester, can fall to beverage bottle bottleneck place by floating water control valve, shutoff bottleneck just, after the water filling of suspension-wire type recoil tester, due to the pressure water control valve sealing bottleneck of water; After well-bucket is static, mention water control valve, current spray from two bend pipe spiral arms, promote well-bucket back-flushing rotary, and water control valve is bubbled through the water column; Suspension-wire type recoil tester has reduced friction and other disturbing factor, has strengthened experiment effect.When experiment, can catch water spray with transparent plastic basin.
