Abstract
The utility model relates to a political teaching experimental apparatus, including upper groove, squeeze receptacle, support column, rubber membrane, the vertical setting of support column that the outer wall was equipped with the ladder platform is on the base, and the chamber is acceptd to the squeeze receptacle and upper groove is all connected on the support column through the horizontal pole, upper tank bottom portion is equipped with the delivery port of directional squeeze receptacle inner chamber, and the squeeze receptacle lower extreme is in the face of answering the rubber membrane to be equipped with toper extrusion piece, be equipped with the solenoid valve on the delivery port of upper groove. Utilize toper extrusion piece extrusion rubber membrane to carry out interesting political point view more directly perceived analysis, solved uninteresting, the abstract problem of political point view explanation, help explaining that the quantitative change arouses the law of qualitative change.
Description
Technical field
The utility model relates to a kind of political class instructional device, is specifically related to a kind of Political Teaching experimental provision that can intuitively explain political point view.
Background technology
In the time of Political Teaching, teacher to quantitative change to qualitative change process instruction, mostly be and use books, chalk and blackboard to impart knowledge to students to student, and the content that politics lesson relates to is not only extensive, and abstract, only rely on very abstract of books, chalk and blackboard, be not easy to student and understand, it is more difficult that student accepts, and teaching efficiency is poor.
Utility model content
In order to solve uninteresting, the abstract problem of political point view explanation, the utility model has designed a kind of colleges and universities Political Teaching appurtenance.
Concrete technology contents of the present utility model is: a kind of Political Teaching experimental provision, comprise upper groove, squeeze receptacle, support column, rubber membrane, the support column that outer wall is provided with ladder platform is vertically arranged on base, squeeze receptacle host cavity and upper groove are all connected on support column by cross bar, cross bar one end is fixedly connected with retainer ring, the other end is connected to by bearing on the ladder platform of support column outer wall, and described squeeze receptacle host cavity and upper groove are assemblied in respectively in its corresponding retainer ring; Squeeze receptacle is assemblied in squeeze receptacle host cavity by the mode being slidably matched, under squeeze receptacle host cavity, edge is outward extended with flange, ring flange is bolted below flange, rubber membrane is fixedly connected on squeeze receptacle host cavity lower surface by ring flange, and ring flange middle part is provided with the through hole matching with squeeze receptacle host cavity; Upper trench bottom is provided with the delivery port that points to squeeze receptacle inner chamber, and the corresponding rubber membrane in squeeze receptacle lower surface is provided with tapered squeezing piece; Described upper groove delivery port is provided with magnetic valve.
Cross bar is connected to corresponding bearing outer wall by the mode of welding; The internal diameter of two retainer rings matches with the external diameter of squeeze receptacle host cavity or upper groove respectively.
Useful technique effect of the present utility model is: utilize tapered squeezing piece extruding rubber membrane to carry out interesting political point view more directly perceived and resolve, solved uninteresting, the abstract problem of political point view explanation, contribute to illustrate that quantitative change causes the rule of qualitative change.
Brief description of the drawings
Accompanying drawing 1 is this apparatus structure sketch;
Accompanying drawing 2 is accompanying drawing 1 partial enlarged drawing.
In figure, 1 is that bearing, 2 is that upper groove, 3 is that magnetic valve, 4 is that support column, 5 is that base, 6 is that cross bar, 7 is that retainer ring, 8 is that squeeze receptacle host cavity, 9 is that tapered squeezing piece, 10 is that squeeze receptacle, 11 is that rubber membrane, 12 is that bolt, 13 is ring flange.
Detailed description of the invention
A kind of Political Teaching experimental provision, referring to Fig. 1-2: comprise upper groove 2, squeeze receptacle 10, support column 4, rubber membrane 11, the support column 4 that outer wall is provided with ladder platform is vertically arranged on base 5, squeeze receptacle host cavity 8 and upper groove 2 are all connected on support column 4 by cross bar 6, cross bar 6 one end are fixedly connected with retainer ring 7, the other end is connected to by bearing 1 on the ladder platform of support column 4 outer walls, and described squeeze receptacle host cavity 8 and upper groove 2 are assemblied in respectively in the retainer ring 7 that it is corresponding; Squeeze receptacle 10 is assemblied in squeeze receptacle host cavity 8 by the mode being slidably matched, 8 times edges of squeeze receptacle host cavity are outward extended with flange, ring flange 13 is connected to flange below by bolt 12, rubber membrane 11 is fixedly connected on squeeze receptacle host cavity 8 lower surfaces by ring flange 13, and ring flange 13 middle parts are provided with the through hole matching with squeeze receptacle host cavity 8; Upper groove 2 bottoms are provided with the delivery port that points to squeeze receptacle 10 inner chambers, and the corresponding rubber membrane 11 in squeeze receptacle 10 lower surfaces is provided with tapered squeezing piece 9; Described upper groove 2 delivery ports are provided with magnetic valve 3.
Cross bar 6 is connected to corresponding bearing 1 outer wall by the mode of welding; The internal diameter of two retainer rings 7 matches with the external diameter of squeeze receptacle host cavity 8 or upper groove 2 respectively.
Upper groove 2 and squeeze receptacle host cavity 8 are separately fixed on corresponding support column 4 ladder platforms by bearing 1, can carry out horizontal direction rotation; Squeeze receptacle 10 is slidedly assemblied in host cavity, and host cavity lower end tapered squeezing piece 9 is conflicted on rubber membrane 11, opens magnetic valve 3 by constantly making squeeze receptacle 10 mass penalties to squeeze receptacle 10 water fillings, and now tapered squeezing piece 9 makes rubber membrane 11 produce deformation; In the time reaching certain water injection rate, crushing block punctures rubber membrane 11, thereby proves more intuitively " quantitative change produces the viewpoint of qualitative change " in Political Teaching.
