Abstract
The utility model relates to an experimental apparatus, specifically speaking relates to a level crossing for portable primary school experiments. Including the picture frame, inlay the level crossing installed in the picture frame and play supporting role's supporting seat, the bottom center of picture frame is equipped with the socket, the supporting seat includes base, sleeve, pillar and positioning bolt, be equipped with the baffle in the inner chamber of base, the top of baffle is the upper plenum, the below of baffle is cavity down, the bottom of cavity is equipped with the closing cap down. The utility model discloses a base both can use as the base that supports when using, also can regard as the packing carton to use, in the time of need carrying or store, disassembles out it to put into the upper plenum to sleeve, pillar and positioning bolt, cover the baffle, lead to the fact the damage in order to prevent them to the mirror surface of level crossing, and then put into down the cavity to the picture frame that is equipped with the level crossing, cover the closing cap at last. Like this, the transportation of both being convenient for is carried, and also convenient the storage is placed.
Description
Technical field
This utility model is related to a kind of experimental apparatus, specifically, is related to a kind of portable primary school experiment plane mirror.
Background technology
In primary school《Science》In the teaching of this subject, to often lead student to be tested, allow student in an experiment
By observing knowledge of natural environment principle.Wherein, the image-forming principle of mirror needs to complete by plane mirror.The experiment of existing primary school is used
The structure of plane mirror mainly includes picture frame, inlays the plane mirror being arranged in picture frame and passive support base.Its shortcoming
Be assembling after mirror can occupy more space, after dismounting, each assembly is more scattered, and in carrying process, plane mirror is broken, both
Be inconvenient to carry, be also not easy to store.
Utility model content
The purpose of this utility model is, provides a kind of portable primary school experiment plane mirror, to solve above-mentioned technology
Problem.
For solving the above problems, this utility model be employed technical scheme comprise that：
A kind of portable primary school experiment plane mirror, including picture frame, inlays the plane mirror being arranged in picture frame and plays support
Effect support base it is characterised in that：The bottom centre of described picture frame is provided with socket；Described support base includes base, sleeve, props up
Post and bolt, the bottom thread of described sleeve is assemblied in the center of base top surface, and described bolt Screw assembly is in set
The upper end of cylinder；The top of described pillar is inserted in socket, and lower end is inserted in sleeve, and is locked by bolt；Described
It is provided with dividing plate, the top of described dividing plate is the upper plenum for holding sleeve, pillar and bolt, described in the inner chamber of base
The lower section of dividing plate is the lower cavity matching with picture frame size, and the bottom of described lower cavity is provided with capping.
Beneficial effect：Compared with prior art, base of the present utility model both can be when being used as the base supporting
It is used it is also possible to use as packing box, when needing to carry or store, disassembled out, and sleeve, pillar and positioning spiral shell
Bolt is put in upper plenum, covers dividing plate, to prevent them from the minute surface of plane mirror is caused damage；Then again equipped with plane mirror
Lower cavity put into by picture frame, finally covers capping.So, both it was readily transported and carried, and be also convenient for storage and place.
