Description
Technical field
The utility model relates to teaching aid technical field, especially relates to a kind of economical management teaching demonstration teaching aid.
Background technology
Science of economic management, in teaching process, can be used a lot of statistical graph and statistical graph and carry out explanation to student and give lessons, allow student be easier to understand.
But existing statistics column diagram mostly is planar graph, be mostly in teaching process to draw on teaching panel, the Statistics Course of science of economic management is more uninteresting and abstract, cause the learning interest of student not high, can not well understand.
Utility model content
Not enough for prior art, technical problem to be solved in the utility model is to provide a kind of economical management teaching demonstration teaching aid, to reach the object of the learning interest improving student.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of economical management teaching demonstration teaching aid, comprise teaching aid box, the case top of described teaching aid box is dull and stereotyped, the flat board of described teaching aid box is arranged side by side one group of through hole, in teaching aid box, corresponding each through hole is provided with a hydraulic cylinder, and hydraulic cylinder is positioned at the below of through hole, the piston rod part of hydraulic cylinder is provided with top board, top board and upper cover of piston rod have statistics column casing, are fixed together at the bottom of the cylinder of statistics column casing with top board, and statistics column casing and top board all can through corresponding through holes; Above teaching aid box two adjacent sides are equipped with teaching aid riser, being hinged with the casing of teaching aid box below of each teaching aid riser, the edge that two teaching aid risers are adjacent are equipped with the magnet of suction mutually.
Further, the edge that described two teaching aid risers are adjacent is provided with the buckle structure that can cooperatively interact.
Described teaching aid riser is drawing board.
The side of described teaching aid box is provided with chamber door.
The lower openings of described statistics column casing is fixed on the cylinder body of hydraulic cylinder, and statistics column casing bottom is telescopic ripple struction.
The utility model compared with prior art, have the following advantages: statistics column diagram solid can present by this economical management teaching demonstration teaching aid, each statistics post can need to carry out height control according to teaching, and three-dimensional statistical graph can improve the learning interest of student, is convenient to understand.
Accompanying drawing explanation
Below the content expressed by each width accompanying drawing of this instructions and the mark in figure are briefly described:
Fig. 1 is the utility model teaching aid structure schematic diagram.
Fig. 2 is the utility model statistics post elevating mechanism schematic diagram.
In figure: 1. teaching aid box, 2. universal wheel, 3. chamber door, 4. teaching aid riser, 5. statistics post, 6. gauge tap, 7. hydraulic cylinder, 8. piston rod, 9. top board.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is described in further detail.
As depicted in figs. 1 and 2, this economical management teaching demonstration teaching aid, comprises the teaching aid box 1 of rectangular structure, teaching aid box 1 is welded by six panels, the case top of teaching aid box 1 is dull and stereotyped, and four, the bottom corner of teaching aid box 1 is equipped with universal wheel 2, is convenient to mobile teaching aid.
The flat board of teaching aid box 1 is arranged side by side six through holes, six through hole uniform intervals are arranged, and the inside of teaching aid box 1 is provided with six hydraulic cylinders 7 for each through hole, and hydraulic cylinder 7 is fixed on the base plate of teaching aid box, and corresponding hydraulic cylinder is positioned at immediately below corresponding through hole.
The side of teaching aid box 1 is provided with chamber door 3, and the following of chamber door 3 is arranged on the casing of teaching aid box by hinge, is provided with lock between the top of chamber door and casing; The setting of chamber door, is convenient to the installation and maintenance of the parts of teaching aid box inside.
Piston rod 8 top of hydraulic cylinder is provided with top board 9, and top board and upper cover of piston rod have statistics column casing, is fixed together at the bottom of the cylinder of statistics column casing with top board, and statistics column casing and top board all through corresponding through hole, can form the elevating mechanism of statistics post.
Hydraulic cylinder is connected with outside hydraulic pump by pipeline, and corresponding each hydraulic cylinder is equipped with the gauge tap 6 of the piston rod lifting of a hydraulic control cylinder on the flat board of teaching aid box, by the work of gauge tap hydraulic control cylinder, thus control the lifting of statistics column casing, six statistics column casings stretching out teaching aid box form the statistics post of the solid of six, make each statistics post 5 can need to carry out height control according to teaching, three-dimensional statistical graph can improve the learning interest of student.
Through hole is square opening, top board is square plate; Or through hole position circular port, top board are circular slab, are arranged to square or circle and are convenient to processing, and also meet the requirement of statistical graph.
The lower openings of statistics column casing is fixed on the cylinder body of hydraulic cylinder, and statistics column casing bottom is telescopic ripple struction; Piston rod 8 is Multi-section telescopic bar, and the range of piston rod is large, statistics column casing can be made to meet differing heights adjustment by the setting of ripple struction.
