Abstract
The utility model provides a conveniently-read densitometer for tests, which is composed of a glass tube with marks, a glass ball, a thin glass tube, a counter weight block, a float frame and a float. The lower end of the glass tube with marks is connected with the glass ball which is connected with the upper end of the thin glass tube, the lower end of the thin glass tube is connected with the counter weight block, one end of the float frame is connected with the upper end of the glass tube, the other end of the float frame is connected with the lower end of the glass tube, and the float is connected to the float frame in a sliding mode. The conveniently-read densitometer is compact in structure and reasonable in design, and can still accurately read density of liquid after the densitometer is taken out from the liquid.
Description
Technical field
The utility model relates to a kind of experiment apparatus, is specifically related to a kind ofly make things convenient for the experiment of reading to use densitometer.
Background technology
In physics, the weight of material is generally represented with proportion, is defined as: the weight of unit volume material is called the proportion of this material.Be expressed as with mathematical expression: proportion=weight/volume.The unit of proportion is with gram/cubic centimetre, kilogram/cubic decimeter or ton/cubic meter etc.When this definition of Learning in School, generally all deepen understanding to do experiment, used instrument is densitometer.Existing densitometer is generally all processed with glass material, and its structure is that the lower end has a weight, and the weight top is connected with a bar handle, is carved with the numerical scale line on the bar handle.Densitometer is put into liquid, and the pairing reading of liquid level is this density of liquid, but under situation such as container is very narrow and small, light is more dim, this densitometric scale is difficult for reading, causing easily bigger error.
The utility model content
To above-mentioned technical deficiency, the purpose of the utility model is to disclose a kind ofly to make things convenient for the experiment of reading to use densitometer.
A kind ofly make things convenient for the experiment of reading to use densitometer; Glass tube, glass bead, thin glass tube, balancing weight, buoy frame and buoy by with scale are formed, and the lower end of having the glass tube of scale is connected with glass bead, and glass bead is connected with the upper end of thin glass tube; The lower end of thin glass tube is connected with balancing weight; an end of buoy frame is connected with the upper end of glass tube, and an other end of buoy frame is connected with the lower end of glass tube, slidely connects buoy on the buoy frame.
The utility model compact conformation, reasonable in design, after densitometer takes out, still can read this density of liquid exactly from liquid.
Description of drawings
Fig. 1 is the structural representation of the utility model, wherein: 1, with the glass tube of scale, 2, glass bead, 3, thin glass tube, 4, balancing weight, 5, the buoy frame, 6, buoy.
Embodiment
Below in conjunction with Figure of description the utility model is described further:
As shown in Figure 1, a kind ofly make things convenient for the experiment of reading to use densitometer, form by glass tube, glass bead, thin glass tube, balancing weight, buoy frame and buoy with scale; The lower end of having the glass tube of scale is connected with glass bead; Glass bead is connected with the upper end of thin glass tube, and the lower end of thin glass tube is connected with balancing weight, and an end of buoy frame is connected with the upper end of glass tube; an other end of buoy frame is connected with the lower end of glass tube, slidely connects buoy on the buoy frame.
When using the densitometer that the utility model provided, densitometer is put into testing liquid, because the effect of balancing weight; Densitometer can be adjusted to plumbness automatically, simultaneously, regulates buoy and indicates in corresponding scale; Then densitometer is taken out, the indicated reading of buoy is this density of liquid.
The utility model compact conformation, reasonable in design, after densitometer takes out, still can read this density of liquid exactly from liquid.
Claims (1)
1. one kind makes things convenient for the experiment of reading to use densitometer; Glass tube, glass bead, thin glass tube, balancing weight, buoy frame and buoy by with scale are formed, and it is characterized in that: the lower end of having the glass tube of scale is connected with glass bead, and glass bead is connected with the upper end of thin glass tube; The lower end of thin glass tube is connected with balancing weight; an end of buoy frame is connected with the upper end of glass tube, and an other end of buoy frame is connected with the lower end of glass tube, slidely connects buoy on the buoy frame.
