Abstract
The utility model discloses a kind of liquid pressure pilot demonstration instrument, including transparent cup body, the fixed cup lid of transparent cup top, the sliding slot being parallel to each other there are two being shaped on the cup lid, sliding block is slidably connected on sliding slot, through-hole is formed on sliding block, through-hole wall, which is pasted, is fixed with elastic ring, and interference is inserted with connecting rod in elastic ring；A side is laterally fixed with the face-up lower hydraulic gage of measurement film in two connecting rods, another side is laterally fixed with measurement pellicular front upper hydraulic gage directed downwardly；Transparent cup body subscript is shown with scale.The utility model structure is simple, easy to use, can intuitively show the intracorporal pressure changing of liquid, overcomes the intuitive prejudice of students, the preconception to correct a mistake.
Description
Technical field
This patent belongs to machinery field more particularly to a kind of liquid pressure pilot demonstration instrument.
Background technique
When student learns pressure related content again, often it is mistakenly considered the size of liquid pressure and liquid container is housed
Shape size is related, it is believed that the water of the bigger container dress of shape quality is more, water volume is bigger, the gravity that water is subject to is also
The bigger pressure generated to liquid is also bigger, this is that most of middle school student are recognized in rigid contact liq pressure due to existing
The wrong preconception for knowing limited experience to usually will appear.In addition, the pressure in the same depth all directions of liquid internal is big
It is small equal, but the classmate for much just having touched liquid pressure thinks that this physics law is difficult to understand for, it is believed that it fills in a reservoir
Liquid only has pressure in downward direction or to be that straight down, that pressure in downward direction just should for gravity suffered by liquid
Greater than the pressure of upward direction and side all directions.And existing test apparatus can not intuitively demonstrate this.
Utility model content
To solve the above problems, the utility model discloses a kind of liquid pressure pilot demonstration instruments.The utility model knot
Structure is simple, easy to use, can intuitively show the intracorporal pressure changing of liquid, overcomes the intuitive prejudice of students, correction
The preconception of mistake.
To achieve the above object, the technical solution of the utility model are as follows:
A kind of liquid pressure pilot demonstration instrument, including transparent cup body, the fixed cup lid of transparent cup top, on the cup lid
Forming slidably connects sliding block on sliding slot, through-hole is formed on sliding block, through-hole wall is pasted there are two the sliding slot that is parallel to each other
It is fixed with elastic ring, interference is inserted with connecting rod in elastic ring；A side is laterally fixed with measurement film in two connecting rods
Face-up lower hydraulic gage, another side are laterally fixed with measurement pellicular front upper hydraulic gage directed downwardly；Transparent cup body subscript shows
There is scale.
Further to improve, sliding block two sides indent is formed with the groove with sliding slot cooperation.
Further to improve, the transparent cup body is glass cup body.
Further to improve, the transparent cup body is detachably connected with cup lid screw thread.
Further to improve, the cup lid is plastic cup cover.
Detailed description of the invention
Fig. 1 is the positive structure schematic of the utility model；
Fig. 2 is the overlooking structure diagram of the utility model；
Fig. 3 is the structural schematic diagram of sliding block.
Specific embodiment
Embodiment 1
A kind of liquid pressure pilot demonstration instrument as shown in Figs. 1-3, including transparent cup body 1, it is fixed at the top of transparent cup body 1
Cup lid 2, forming slidably connects sliding block 4 there are two the sliding slot 3 being parallel to each other on sliding slot 3 on the cup lid 2, on sliding block 4 at
Shape has through-hole 10, and 10 inner wall of through-hole, which is pasted, is fixed with elastic ring 11, and interference is inserted with connecting rod 5 in elastic ring 11；Two connections
A side is laterally fixed with the face-up lower hydraulic gage 7 of measurement film on bar 5, another side is laterally fixed with measurement film
Face-down upper hydraulic gage 6；Scale 8 is labeled on transparent cup body 1.
When the utility model is used, connecting rod can be pushed up and down, can measure the pressure of different water depth after positioning, drills
Show with depth of water difference, the different principle of pressure, may then pass through the translation of sliding slot 3 or so, measure the same depth of water, different location
Pressure, so that the same depth of water is demonstrated, the identical principle of pressure.Mobile and rotation connecting rod 5, so that the upper surface of lower hydraulic gage 7
It is bonded with the lower surface of upper hydraulic gage 6, is then translated apart from, lower hydraulic gage 7 and upper hydraulic gage 6 is read respectively, to demonstrate
Pressure in downward direction is equal with the pressure of upward direction.
4 two sides indent of sliding block is formed with the groove 9 cooperated with sliding slot 3.
Transparent cup body 1 is glass cup body.
Transparent cup body 1 is detachably connected with 2 screw thread of cup lid.
Cup lid 2 is plastic cup cover.
Although the embodiments of the present invention have been disclosed as above, it is not restricted to institute in specification and embodiment
Column use, it can be applied to various fields suitable for the present invention completely, for those skilled in the art, can
Easily realize other modification, therefore without departing from the general concept defined in the claims and the equivalent scope, this is practical
It is novel to be not limited to specific details and the legend herein shown with description.
