Description
Technical field
The utility model provides a kind of interested testing device of verification surface tension of liquid, belongs to experimental teaching equipment neck
Domain.
Background technology
The surface that surface tension of liquid Producing reason, which is liquid, to be contacted with gas is called superficial layer there are a thin layer,
Molecular proportion liquid internal in superficial layer is sparse, and intermolecular distance is larger than liquid internal, intermolecular interaction table
It is now gravitation.Just as spring is pulled open, spring is showed instead with the trend shunk.Since surface tension of liquid can not
See, the presence of surface tension of liquid is verified frequently with the method for some experiments in teaching.Currently, on primary school classroom below
Through imparting knowledge to students frequently with " a scrap of paper of disagreeable soap " this Interesting Tests, it is packed into clear water in washbowl, is spread on the water surface
The a scrap of paper enameled, is then inserted in soap among a scrap of paper, and observation a scrap of paper quickly floats sidewise phenomenon.Due to not having
Special experimental provision, typically instructor fix the substance containing surfactant such as soap with hand or rope, are easy
Landing causes experiment effect bad.
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 a kind of Interesting Tests dresses of verification surface tension of liquid
It sets, including basin body, transparent housing and the clamping device for object to be clamped, the transparent housing is located at the top of basin body,
It is detachably connected with basin body upper epitaxial；Through-hole is provided at the top of transparent housing, it is saturating that described clamping device one end passes through through-hole to enter
Inside bright outer cover, other end size is more than through-hole.
Wherein, the clamping device be located at one end inside transparent housing be equipped with spring clip, the fertilizer for experiment to be clamped
The object containing surfactant such as soap.
Further, the clamping part of the spring clip is through there is a bolt, and bolt passes through soap, to prevent soap from falling
It falls, influences experiment effect.
The outer wall of the basin body is equipped with the water pipe inside connection basin body, the water filling into basin body by the water pipe.
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 osculum, facilitates the liquid discharge inside basin body.
Advantageous effect：
1, utility model device is equipped with special soap clamping device, can ensure that soap does not fall in experimentation
It falls, influences to realize effect；
2, utility model device is equipped with transparent housing, can effectively prevent the pollution to internal liquid such as external dust；
3, utility model device is equipped with water pipe and water pipe fixed ring inside connection basin body, the convenient behaviour in various height
Make fast water injection on platform.
Description of the drawings
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 present apparatus；
Fig. 2 is the overlooking structure diagram of the present apparatus；
Fig. 3 is the clamping device structural schematic diagram of the present apparatus.
Specific implementation mode
According to following embodiments, the present invention may be better understood.
As illustrated in fig. 1 and 2, which includes basin body 1, transparent housing 2 and clamping device 3, and transparent housing 2 is located at
The top of basin body 1 is detachably connected with 1 upper epitaxial of basin body, primarily serves and protect internal liquid not contaminated, while facilitating sight
The purpose of experiment is examined, transparent housing 2 normally without dismantling, needs just to dismantle cleaning when cleaning；2 top of transparent housing is provided with a length
The through-hole 4 of bar shaped, 3 one end of clamping device pass through through-hole 4 enter transparent housing 2 inside, the other end due to size be more than through-hole, therefore
Positioned at 2 top of transparent housing, facilitates and be removed and placed into entire clamping device 3；1 outer wall of basin body is equipped with inside connection basin body 1
Water pipe 5, the lower section of upper epitaxial are equipped with the fixed ring 6 of fixed water pipe 5, and when use takes out water pipe 5, and connection hand tap can be to
Water filling in basin body 1；1 bottom of basin body is equipped with osculum, and internal liquid is discharged.
As shown in figure 3, clamping device 3 be located at one end inside transparent housing 2 be equipped with spring clip 33, other end handle 31 by
It is more than through-hole 4 in size, therefore positioned at 2 top of transparent housing, facilitate and clamping device 3 is taken out and is put into；The clamping of spring clip 33
Portion, which is run through, has a bolt 34, bolt 34 to further prevent soap to fall across soap；The company of being equipped between handle 31 and spring clip 33
Bar 32.
In use, first taking out clamping device 3, it is filled into basin body 1 by water pipe 5 and requires level scale；In soap 7
Middle part is punched, and by spring clip 33 so that clamping part is aligned with the hole at 7 middle part of soap, by bolt 34 through soap 7 and spring
The clamping part of folder 33 simultaneously tightens fixation；After water surface calmness in basin body 1, colored shredded paper is sprinkled into basin body 1 by through-hole 4
Then soap 7 is passed through through-hole 4 to be inserted into the water surface by piece by clamping device 3, observation a scrap of paper quickly floats sidewise phenomenon,
It takes out soap 7 and adds a scrap of paper, experimental phenomena is repeated again insertable into the water surface after standing a period of time；By basin body after experiment
Water and a scrap of paper in 1 are discharged together, and rotating handles 31 to form current path between 1 bottom drain holes of through-hole 4 and basin body,
So as to which quickly soap 7 and basin body 1 are dried up.
The utility model provides a kind of thinking and method of the interested testing device of verification surface tension of liquid, specific real
Now there are many method of the technical solution and approach, and the above is only the preferred embodiment of the utility model, it is noted that right
