Abstract
The utility model provides a liquid viscosity coefficient measuring experimental device composed of four parts including a support device, a glass tube device, a glass tube cover and a small steel ball launching device. The support device is composed of support legs (2) installed on a pedestal (1), a level bubble (3) and a bolt (4). The pedestal (1) can be kept horizontal through adjusting heights of the support legs (2). Whether the pedestal (1) is horizontal or not can be checked by the level bubble (3). The glass tube device is made of a glass tube (7) with an enclosed bottom. The bottom of the glass tube (7) is provided with a slightly larger pedestal. The liquid viscosity coefficient measuring experimental device is simple in structure and principle and convenient to use. The small steel ball placing position can be controlled accurately and no pollution to to-be-tested liquid may be caused.
Description
Technical field
The utility model relates to the experimental provision in physics teaching, is specially a kind of coefficient of viscosity determination experiment device.
Background technology
The coefficient of viscosity determination experiment device using at present, using tweezers clamping small ball to put into the process of testing liquid, due to the sticking action between tweezers and small ball, makes small ball and is not easy to put into testing liquid; Secondly, in the process of tweezers contact measured liquid, can liquid be produced and be polluted, cause experimental result to occur deviation; Finally, in experiment, put into along the glass tube liquid level center of circle for guarantee small ball, generally adopt ocular estimate to carry out, performance accuracy is lower, is unfavorable for the accurate control of experiment.
Summary of the invention
For the small ball of the coefficient of viscosity determination experiment device that overcomes current use is difficult for the problem that can pollute while putting into testing liquid, tweezers contact measured liquid, small ball can not accurately be put into along the liquid level center of circle, the utility model provides a kind of coefficient of viscosity determination experiment device, this device is reasonable in design, simple to operate, and can improve the precision of experiment.
The utility model solves the scheme that its technical matters adopts: a kind of coefficient of viscosity determination experiment device, is characterized in that: this utility model is made up of bracing or strutting arrangement, glass tube device, glass tube lid and small ball emitter four parts.Bracing or strutting arrangement is made up of the feet 2, air level 3 and the bolt 4 that are arranged on base 1, can make base 1 maintenance level by the height that regulates feet 2, and whether base 1 level can be checked by air level 3; Glass tube device is made by the glass tube 7 of sealed bottom, glass tube 7 bottoms are with slightly large base, bolt 4 is fixed on base 3 through the aperture 5 on glass tube base, is carved with groove 9, lower groove 6 on glass tube 7, and interior contained testing liquid 8 liquid levels of glass tube 7 are higher than upper groove 9; Glass tube lid is formed by hard round plastic cover plate 10 and plastic round tube 11 bondings, on glass tube cover plate 10, have a circular hole 12, plastic round tube 11 external diameters are slightly less than glass tube 7 internal diameters, glass tube cover plate 10 is covered in the top of glass tube 7, and plastic round tube 11 is stuck in the inwall of glass tube 7 in case 10 landings of glass tube cover plate; Small ball emitter is made up of funnel 14 and small ball 15, funnel 14 is made up of organic glass, its bottle neck 13 internal diameters are slightly larger than small ball diameter, funnel 14 stretches into glass tube 7 by the circular hole 12 on glass tube cover plate 10 and approaches with the liquid level of testing liquid 8, and small ball 15 can slip into along hopper walls the liquid level home position of testing liquid 8 from bell mouth discharges.
The utility model structural principle is simple, easy to use, and the accurate control that is beneficial to small ball and puts into position is pollution-free to testing liquid.By open the circular hole of same diameter on different-diameter glass tube cover plate, can realize multitube and share a small ball emitter, reduce instrument cost.
