Description
Technical field:
The utility model belongs to Physical Experiment technique with the apparatus field, is specifically related to a kind of Novel physical teaching experiment lift lens.
Background technology:
In long-term experiment practice; in convex lens experimentation, often can adjust convex lens height doing; generally can use threaded rod to adjust height; and use threaded rod adjustment highly limited; often cannot reach experimenter's height; and use for a long time threaded rod to be easy to slide fastener, bring larger error cannot embody experiment effect to experimental result.
Utility model content:
The purpose of this utility model is: can adjust at any time convex lens height in order to solve to do in convex lens experimentation, and can unrestrictedly adjust convex lens height or minuent, adjusting the height that highly can know convex lens simultaneously, facilitate experimenter to test the time of measuring convex lens height of simultaneously saving, its technical scheme is as follows:
A kind of experiment lift lens for Novel physical teaching, it comprises convex lens 1, fixed placement groove 2, latch plate 3, puller strap 4, through hole 5, base 6, rotating shaft 7, driving gear 8, transmission gear 9, crank 10, it is characterized in that: described convex lens 1 surface, below is fixedly connected with fixed placement groove 2, 2 times top end surface left and right sides edges of described fixed placement groove are fixedly connected with latch plate 3, 3 times top end surfaces of described latch plate are fixedly connected with base 6, described base 6 upper surface middles are provided with through hole 5, surperficial middle, the inner left and right of described through hole 5 is fitted with rotating shaft 7, described rotating shaft 7 upper surface middles are fixedly connected with puller strap 4, and described puller strap 4 other ends are fixedly connected on described fixed placement groove 2, described base 6 right lateral surface middles are fitted with described transmission gear 9, described base 6 top edges places, right side are fixedly connected with driving gear 8, described driving gear 8 right lateral surface are fitted with crank 10, described fixed placement groove 2 upper surfaces are circular arc type, described fixed placement groove 2 upper surface circular arc bosom places are provided with the draw-in groove matching with described convex lens 1, and described fixed placement groove 2 is concentric circles with described convex lens 1, described fixed placement groove 2 two ends, left and right are respectively fixedly connected with fixed head, the left top of described rotating shaft 7 is fixedly connected with described transmission gear 9, and described rotating shaft 7 has with described transmission gear 9, and joint pin is fastened to each other to be connected.
The beneficial effects of the utility model are: can adjust at any time convex lens height in order to solve to do in convex lens experimentation, and can unrestrictedly adjust convex lens height or minuent, adjusting the height that highly can know convex lens, facilitate experimenter to test the time of measuring convex lens height of simultaneously saving simultaneously.
Brief description of the drawings:
Fig. 1 is one-piece construction schematic diagram of the present utility model.
Embodiment:
Use lift lens with reference to a kind of Novel physical teaching described in Fig. 1 with testing, it comprises convex lens 1, fixed placement groove 2, latch plate 3, puller strap 4, through hole 5, base 6, rotating shaft 7, driving gear 8, transmission gear 9, crank 10, it is characterized in that: described convex lens 1 surface, below is fixedly connected with fixed placement groove 2, 2 times top end surface left and right sides edges of described fixed placement groove are fixedly connected with latch plate 3, 3 times top end surfaces of described latch plate are fixedly connected with base 6, described base 6 upper surface middles are provided with through hole 5, surperficial middle, the inner left and right of described through hole 5 is fitted with rotating shaft 7, described rotating shaft 7 upper surface middles are fixedly connected with puller strap 4, and described puller strap 4 other ends are fixedly connected on described fixed placement groove 2, described base 6 right lateral surface middles are fitted with described transmission gear 9, described base 6 top edges places, right side are fixedly connected with driving gear 8, described driving gear 8 right lateral surface are fitted with crank 10, described fixed placement groove 2 upper surfaces are circular arc type, described fixed placement groove 2 upper surface circular arc bosom places are provided with the draw-in groove matching with described convex lens 1, and described fixed placement groove 2 is concentric circles with described convex lens 1, described fixed placement groove 2 two ends, left and right are respectively fixedly connected with fixed head, the left top of described rotating shaft 7 is fixedly connected with described transmission gear 9, and described rotating shaft 7 has with described transmission gear 9, and joint pin is fastened to each other to be connected.
When use, first holding post crank 10 rotates driving gear 8 and is with nutating gear 9, drive shaft 7 in through hole 5 is wrapped in puller strap 4 on transmission gear 7 simultaneously, and latch plate 3 is compressed simultaneously to fixed placement groove 2 and convex lens 1 decline is adjustable height, and can record convex lens 1 height by the lip-deep rule of puller strap 4.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art make in essential scope of the present utility model, also should belong to protection domain of the present utility model.
