Description

Teaching demonstration device and methods of exhibiting

Technical field:

The present invention relates to a kind of teaching demonstration device and methods of exhibiting, belong to teaching field.

Background technique:

Showing stand can be all used in carrying out teaching process at present, existing showing stand is all the form of common frame body, displaying Content is single, can drench the books on showing stand when cannot plurality of kinds of contents be carried out while be shown, while encounter the rainy day, cause It is inconvenient to show.

Summary of the invention:

The problem of present invention aim to address existing showing stands cannot block rain, shows uncomplete content face, providing one kind can Content variety, the teaching demonstration device and methods of exhibiting of rain cover are shown to improve.

Above-mentioned purpose is realized by following technical scheme:

A kind of teaching demonstration device, composition includes: pedestal, is fixed with central axis on the pedestal, on the central axis Portion is bolted to connection with hydraulic cylinder, the hydraulic cylinder top with block along being fixedly connected, on the central axis with Two fulcrum bar components being distributed up and down are connected by bearing, are fixedly connected outside the fulcrum bar component with publicity cylinder, under being located at Fulcrum bar component lower end described in portion is fixedly connected with sleeve, and the transmission shaft on the sleeve and motor is connected by belt.

The teaching demonstration device, described blocks along being top in cone, and lower part is in conical integral type knot Structure.

The teaching demonstration device, the fulcrum bar component are made of four struts being distributed according to even circumferential Structure.

The diameter ratio of the teaching demonstration device, the sleeve and the transmission shaft is 10:1.

The teaching demonstration device is fixed with controller on the pedestal.

A kind of methods of exhibiting of teaching demonstration device, motor is bolted on pedestal, the transmission shaft of motor with The diameter ratio of sleeve is 1:10, and tensioning wheel, the bracket and base rotation of tensioning wheel are set between the transmission shaft and sleeve of motor It connects and is capable of fixing, the angle of tensioning wheel can be adjusted, start motor, the transmission shaft band moving sleeve on motor rotates, thus real Now publicize the rotation of cylinder.

The utility model has the advantages that

1. the present invention publicizes the rotation of cylinder by can be realized automatically, 360 degree rotation can be carried out to content is shown, it is convenient more Student sees, while the form of publicity cylinder is arranged, and can disposably show plurality of kinds of contents, improves and shows the comprehensive of content.

2. the transmission shaft of present invention setting motor and the diameter ratio of sleeve are 1:10, it is ensured that publicity cylinder rotates uniformly, It is convenient for student viewing simultaneously by its its velocity of rotation.

3. edge is blocked in present invention setting, blocks and block and rise along can be realized by driving hydraulic cylinder, in the rainy day It can decline and will advertise that cylinder blocks, prevent from drenching, when fine day, which is risen, facilitates displaying.

4. base side of the present invention is disposed with a circle can when student's distance is shown within the scope of device 0.5m close to switch So that motor stops, so that publicity cylinder stops operating, guarantee that student can see the content of publicity clearly.

Detailed description of the invention:

Attached drawing 1 is structural schematic diagram of the invention;

Attached drawing 2 is the structural schematic diagram of fulcrum bar component;

In figure: 1, motor;2, belt;3, cylinder is publicized;4, fulcrum bar component;5, central axis;6, hydraulic cylinder;7, headlamp;8, it blocks Edge;9, sleeve;10, controller;11, strut.
