Description
Technical field
The utility model provides a kind of interested testing device for verifying gas pressure intensity, belongs to experimental teaching clothing arts.
Background technique
Air pressure refers to the hydrostatic pressure that gas applies certain point, and gas pressure intensity Producing reason is bulk gas point
Son generates lasting, the random shock of chamber wall.Atmospheric pressure refers to the pressure that the air of some position on the earth generates.
For the air of earth surface by gravity, it is not equal for producing atmospheric pressure earth air above layer density therefrom
, close to larger, the high-rise rarefaction of air of atmospheric density of surface layer, density is smaller.Since gas pressure intensity is invisible, imparting knowledge to students
In the presence of gas pressure intensity is verified frequently with the method for some experiments.Currently, through frequently with " gluttonous on primary school classroom below
Bottle " this Interesting Tests imparts knowledge to students, hot water is packed into bottle, the cooked egg of decladding is placed on bottleneck, then carefully
Bottle is put into a basin cold water, observation egg fall into the experimental phenomena in bottle.It is real due to no special experimental provision
Egg and bottle in testing all are disposably, to throwaway, cause very big waste.
Utility model content
Purpose of utility model: technical problem to be solved in the utility model is in view of the deficiencies of the prior art, to provide one
Kind it can reuse, is easily operated, conveniently observing the experimental provision of experiment effect.
In order to solve the above-mentioned technical problem, the utility model discloses the interested testing devices of verifying gas pressure intensity, including
Basin body, turnover bracket and vial, the turnover bracket are located at the two sides of basin body, fix bottom and the bottle of vial respectively
Neck is overturn vial by rotating；The vial bottom opening, opening are equipped with sealing-plug；Pass through turnover bracket
Vial is turned upside down in rotation, and to prevent from scalding, the egg in inhaler can be taken out by extracting sealing-plug.
Wherein, the turnover bracket includes the shaft of the side wall across basin body, and shaft one end is equipped with handle, and the other end is equipped with
Spring clip clamps bottom and the bottleneck of vial by spring clip respectively.
The basin body outer wall is equipped with the water pipe inside connection basin body, is filled the water by the water pipe into basin body.
The lower section of the basin body upper epitaxial is equipped with the fixed ring of fixed water pipe, and one circle of fixed ring setting, water pipe is when not used
Basin body outer wall fixed placement can be prolonged.
The basin bottom is equipped with drainage hole, facilitates the liquid discharge inside basin body.
The utility model has the advantages that
1, the application device vial bottom opening, opening set sealing-plug, will be on vial by turnover bracket rotation
Lower reverse, extraction of closure plug can take out the egg in inhaler, convenient for recycling；
2, the application device is equipped with water pipe and water pipe fixed ring inside connection basin body, and the convenient operation in various height is flat
Fast water injection on platform.
Detailed description of the invention
The utility model is done with reference to the accompanying drawings and detailed description and is further illustrated, the utility model
Above-mentioned and/or otherwise advantage will become apparent.
Fig. 1 is the positive structure schematic of the device；
Fig. 2 is the structural schematic diagram when device vial is reverse；
Fig. 3 is the water pipe structure schematic diagram of device basin body outer wall setting.
Specific embodiment
According to following embodiments, the present invention may be better understood.
As illustrated in fig. 1 and 2, which includes basin body 1, turnover bracket 2 and vial 4, and two turnover brackets 2 distinguish position
In the two sides of basin body 1, turnover bracket 2 includes the shaft 21 across the side wall of basin body 1, and 21 one end of shaft is equipped with handle 22, another
End is equipped with spring clip 3, and the spring clip 3 of two sides clamps bottom and the bottleneck of vial 4 respectively, is rotated and is driven by turnover bracket 2
Vial 4 is overturn, to avoid scalding；4 bottom opening of vial, opening are equipped with sealing-plug 5.
As shown in figure 3,1 outer wall of basin body is equipped with the water pipe 6 inside connection basin body 1, the lower section of 1 upper epitaxial of basin body is equipped with solid
Determine the fixed ring 61 of water pipe 6,1 bottom of basin body is equipped with drainage hole.
In use, moving upwards through bottom and the bottleneck that spring clip 3 clamps vial 4 respectively, vial 4 for 4 mouthfuls of vial
It is sealed with sealing-plug 5, hot water is packed into vial 4, and the cooked egg of decladding is placed on bottleneck, taken out water pipe 6 and connect hand
Faucet injects cold water into basin body 1, until reaching requirement level scale in basin body 1, observation egg was inhaled into showing in vial 4
As；After egg is inhaled into bottle, vial 4 is driven to overturn by turnover bracket 2, so that vial 4 turns upside down, bottom at this time
Upper, the sealing-plug 5 for extracting bottom can take out the egg in inhaler in portion, to reuse in test next time.
The utility model provides the thinking and method of a kind of interested testing device for verifying gas pressure intensity, and specific implementation should
There are many method and approach of technical solution, and the above is only the preferred embodiment of the utility model, it is noted that for this
For the those of ordinary skill of technical field, without departing from the principle of this utility model, several improvement can also be made
And retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.Each composition portion being not known in the present embodiment
The available prior art is divided to be realized.
