Problems solved by technology

[0003] In the process of economic management teaching, the teacher demonstrates the content of the lecture through the demonstration device, and usually needs to show the content after the on-site writing on the blackboard to the students. Because the structure of the demonstration teaching aids is too fixed, it is not easy to adjust, so the teacher needs to keep it while writing on the blackboard. Writing in a specific posture makes the arms easy to fatigue, which is not conducive to the smooth development of teaching. Therefore, a teaching aid for economic management teaching operation demonstration is now provided to solve the above technical problems

Embodiment 1

[0022] see Figure 1-4 , a kind of teaching aid for economic management teaching operation demonstration, comprising a chassis 1, a fixed frame 17 is arranged above the chassis 1, a screw rod 16 is horizontally arranged on the fixed frame 17 in a rotating manner, and a threaded connection sleeve on the screw rod 16 is provided with a threaded sleeve block 14, Display board 8 is hinged on fixed frame 17, and display board 8 is used to place the economic management blackboard writing material that will demonstrate, and teacher can carry out blackboard writing with display board 8 as support.

[0023] An adjusting rod 12 is hinged between the display board 8 and the threaded sleeve block 14, and a transmission box 7 is fixed on the side wall of the fixed frame 17, and a stepping motor 4 is fixed in the transmission box 7, and a drive shaft is coaxially fixed on the output shaft of the stepping motor 4. The gear 5 and the driving gear 5 are meshed with a driven gear 6 sleeved and ...

Embodiment 2

[0027] In order to make the teaching content on the display board 8 get a better display effect, on the basis of Embodiment 1, a threaded sleeve 20 is installed vertically in a rotating manner on the chassis 1, and the threaded sleeve 20 is internally threaded and installed with an upper end. The threaded column 19 pivotally connected to the bottom of the fixed frame 17, the outer wall of the threaded sleeve 20 is circumferentially sleeved and fixed with the lifting hand wheel 2 .

[0028] By turning the lifting hand wheel 2, the threaded sleeve 20 can be driven to rotate, and the rotation of the threaded sleeve 20 can realize the lifting of the threaded column 19 threaded with it, and then realize the adjustment of the height of the fixed frame 17. Further, the threaded sleeve 20 The upper and lower ends are vertically provided with abutment springs 21 respectively abutting against the lower end of the threaded column 19 and the inner bottom of the threaded sleeve 20. The abut...

Abstract

The invention discloses an economic management teaching operation demonstration teaching aid and relates to the technical field of a demonstration device. The teaching aid comprises a chassis, on which a fixed mount is arranged. A lead screw is rotatably and horizontally arranged on the fixed mount. The lead screw is in threaded connection and sleeved with a threaded sleeve block. A display boardis hinged to the fixed mount. An adjustment lever is hinged between the display board and the threaded sleeve block. A transmission case is fixed on the sidewall of the fixed mount. An output shaft ofa stepping motor is coaxially fixed with a drive gear, which is engaged with a driven gear which sleeves and is fixed with the lead screw. Free angle of the display board can be realized when drivenby the stepping motor, thus being convenient for the teacher to lay the display board flat for board writing and effectively reducing fatigue of the teacher's arm. Height adjustment of the fixed mountcan be realized by rotating and lifting a hand wheel. Rotation of the fixed mount can be realized when driven by a servo motor. Thereby, the teaching content on the display board is displayed in an all-round way, which greatly improves the teaching quality of economic management.

Description

technical field [0001] The invention relates to the technical field of demonstration devices, in particular to an economic management teaching operation demonstration teaching aid. Background technique [0002] Economy is the creation, transformation and realization of value. Human economic activities are activities that create, transform and realize value and meet the needs of human material and cultural life. The general term for the overall dynamic phenomenon of distributing all materials. This concept refers to the housework management of a family at the micro level, and the national economy of a country at the macro level. In this dynamic whole, it includes human production, savings, exchange, and distribution. activities; production is the basis of this dynamic, and distribution is the end of it. [0003] In the process of economic management teaching, the teacher demonstrates the content of the lecture through the demonstration device, and usually needs to show the c...
