Utility model works principle: in use, filter paper is clamped by fixing clamp, lid and chromatography column being fastened,
Reverse starting motor, motor reversal drive runner reversion, and traction rope starts to extend when runner inverts, movable pulley when traction rope extends
Because gravity is slided and moved down on traction rope, fixing clamp is driven to move down when movable pulley moves down, similarly, forward direction opens
When dynamic motor, movable pulley drives fixing clamp to move up.
The utility model has the following beneficial effects: positive and negative rotation of this programme by motor, controls the extension and contraction of traction rope,
The adjusting of filter paper height, has reached quick and convenient in experimentation when controlling the lifting of fixing clamp in turn, and then realizing experiment
Adjusting traction rope beneficial effect, reduce adjust traction rope when caused by waste of time.
Further, the upper surface of the lid is equipped with solar panel, and solar panel and battery pass through cable
Connection.It is intended that charge the battery by solar panel, reducing the consumption of the energy.
Further, the side wall of the lid be equipped with normal inching turning switch and reverse inching turning start, normal inching turning switch and
Reverse inching turning switch passes through cable connection with motor.It is intended that being realized by normal inching turning switch and reverse inching turning switch
To the point operation control of motor, adjusted convenient for the adjustable height of fixing clamp.
Further, the clamping face of the fixing clamp is equipped with rubber pad.It is intended that preventing fixing clamp when clamping filter paper
Filter paper is clipped broken, the breakage of filter paper is caused.
Further, the rubber pad is equipped with anti-skid chequer.It is intended that steady when further increasing fixing clamp clamping filter paper
It is qualitative, prevent filter paper from falling.
Further, the bottom surface of the lid is fixedly connected with vertical slide bar, slidably connects slip pipe on slide bar, on slip pipe
It is fixedly connected with strut, the one end of strut far from slip pipe and movable pulley are rotatablely connected.It is intended that passing through such anti-stop of setting
There is the case where double swerve in sliding process in pulley.
Detailed description of the invention
Fig. 1 is a kind of schematic diagram of the structure of the chromatography column of adjustable paper chromatography height of the utility model；
Fig. 2 is circuit connection diagram in Fig. 1.
Specific embodiment
It is further described below by specific embodiment:
Appended drawing reference in Figure of description include: solar panel 1, normal inching turning switch 2, lid 3, chromatography column 4,
