Abstract
The utility model discloses a double-side pressure gage which comprises a base, a panel vertically arranged on the base, a U-shaped glass tube provided with colorful liquid, and a pressure sensing head; a U-shaped slot is arranged on the panel; the U-shaped glass tube is embedded in the U-shaped slot; scales are marked on the two sides of the panel matched with the U-shaped glass tube; the pressure sensing head is communicated with one end of the U-shaped glass tube through a hose; liquid column and scales can be observed from the two sides of the panels in the double-side pressure gage; when a teacher is teaching and demonstrating, the teacher operates, reads and observes at one side of the panel, while students read and observe at the other side of the panel; therefore, the sights of the students can not be shielded, the students are not influenced to observe, and operating of the teacher and observing of the students can be implemented simultaneously; moreover, the double-side pressure gage is convenient to operate and observe, and has good teaching and demonstrating effects.
Description
Technical field
The utility model relates to a kind of piezometer, is specifically related to a kind of piezometer of being convenient to teaching demonstration.
Background technology
Existing physics teaching in secondary school demonstration liquid, the used pressure of gas pressure intensity are counted the single face display structure, because only being arranged, one side can see scale and fluid column, when the teacher carries out teaching demonstration, need stand in the panel front operates and observes, block student's sight line easily, operation of teacher and observation of students can not be carried out simultaneously, influence the teaching demonstration effect.
Therefore, need a kind of piezometer of being convenient to teaching demonstration of design, the teacher can not blocked student's sight line when demonstration, can not influence observation of students, and operation of teacher and observation of students can be carried out simultaneously.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of two-sided piezometer, and the teacher can not blocked student's sight line when demonstration, can not influence observation of students, and operation of teacher and observation of students can be carried out simultaneously.
Two-sided piezometer of the present utility model, comprise base, vertically be built up in the panel on the base, the U-shaped glass tube that colored liquid is housed and pressure inductive head, have the U-shaped groove on the described panel, described U-shaped glass tube embeds in the U-shaped groove, described panel two sides and U-shaped glass tube corresponding position all indicate scale, and described pressure inductive head is communicated with a port of U-shaped glass tube by flexible pipe.
Further, described panel is made by plank.
The beneficial effects of the utility model are: two-sided piezometer of the present utility model, all can be observed fluid column and scale from the panel two sides, when the teacher carries out teaching demonstration, one side operation and reading at panel are observed, and the student observes at panel another side reading, can not block student's sight line, can not influence observation of students, operation of teacher and observation of students can be carried out simultaneously, and operation and observation are convenient, and teaching demonstration is effective.
Description of drawings
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing the utility model is described in further detail, wherein:
Fig. 1 is a structural representation of the present utility model.
Embodiment
Fig. 1 is a structural representation of the present utility model, as shown in the figure, two-sided piezometer of the present utility model, comprise base 1, vertically be built up in the panel 2 on the base 1, the U-shaped glass tube 3 that colored liquid is housed and pressure inductive head 4, have U-shaped groove 5 on the described panel 2, described U-shaped glass tube 3 embeds in the U-shaped groove 5, and described panel 2 two sides and U-shaped glass tube 3 corresponding positions all indicate scale, and described pressure inductive head 4 is communicated with a port of U-shaped glass tube 3 by flexible pipe 6.All can be observed fluid column and the scale (one side of only having drawn panel 2 figure from panel 2 two sides, its another side is to that indicated in the drawings identical), when the teacher carries out teaching demonstration, one side operation and reading at panel 2 are observed, and the student observes at panel 2 another side readings, and operation of teacher and observation of students can be carried out simultaneously.
As further improvement of the utility model, described panel 2 is made by plank; Plank is cheap and easy to get, and opens the U-shaped groove on plank, operates comparatively simply, helps promotion and application of the present utility model.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although by the utility model being described with reference to preferred embodiment of the present utility model, but those of ordinary skill in the art is to be understood that, can make various changes to it in the form and details, and the spirit and scope of the present utility model that do not depart from appended claims and limited.
Claims (2)
1. two-sided piezometer, comprise base, vertically be built up in the panel on the base, the U-shaped glass tube that colored liquid is housed and pressure inductive head, it is characterized in that: have the U-shaped groove on the described panel, described U-shaped glass tube embeds in the U-shaped groove, described panel two sides and U-shaped glass tube corresponding position all indicate scale, and described pressure inductive head is communicated with a port of U-shaped glass tube by flexible pipe.
2. two-sided piezometer according to claim 1 is characterized in that: described panel is made by plank.
