Description

Experiment device for teaching

Technical field

The utility model relates to teaching tool technical fields, and in particular to a kind of experiment device for teaching.

Background technique

In current education activities, it is often necessary to show learning Content to student by way of writing on the blackboard.Especially English The class of languages subject such as language, needs to write a large amount of text, and workload is bigger.Although multimedia obtains in modern teaching It is widely applied, but in middle and primary schools still based on writing on the blackboard, teacher needs to write on the blackboard the word to be learnt, and leads Student learns its pronunciation, meaning, usage, and the correct Writing method of English learning is also needed for primary school education.But not Pipe is writing on the blackboard or multimedia, after classroom terminates and is inconvenient to retain, student cannot be allowed to consolidate content in time.Clipboard On the one hand book increases the workload of teacher, need to write a large amount of text；Also without writing lattice on another aspect normal blackboard Son can only sense text and write standard, and not intuitively, student is difficult the cognition for having deep to the writing of specification.

Summary of the invention

The above-mentioned the deficiencies in the prior art of the utility model provide the easy to use, normalized written of one kind and help to consolidate The teaching tool of learning Content.

In order to solve the above technical problems, the utility model adopts the following technical solution:

Design a kind of experiment device for teaching, including pedestal, support rod, displaying cylinder；Support rod is atmospheric pressure pole, its both ends point It is not fixedly connected on base upper surface and shows cylinder lower surface；Show that cylinder includes the writing blank or green with four lines, three lattice Plate；It shows and is also evenly distributed with the isolation strip formed by different colours coating on cylinder.Teacher, which can shift to an earlier date, writes institute on showing cylinder The content to be learnt, rotary barrel are given lessons, and can stay at classroom after class and student is facilitated to consolidate in real time.

Further, it shows that cylinder can be an entirety, can also be formed by tired fold of multiple discrete cubic units, often A cubic units upper surface is provided with card slot, and lower surface is provided with protrusion corresponding with card slot.It is convenient using separated structure Disassembly and replacement.

Further, show that cylinder section is round or regular hexagon.Round more smooth suitable writing phrase or sentence, just Hexagon is then more suitable for writing letter, word or phonetic symbol.

Further, base lower surface is equipped with idler wheel.Not only can make to move it is more convenient, but also can be anti-when needing fixed Sliding stop.

Further, pedestal and support rod are stainless steel material.It is sturdy and durable, while weight is also sufficiently large, prevents from inclining ?.

Compared with prior art, the advantageous effects of the utility model are:

1. the utility model is easy to use, plane formula clipboard is converted into solid type, so that its movement and use are all non- Normal convenience.

2. english writing four lines, three lattice are provided on the utility model cylinder, it being capable of specification blackboard handwriting in English.

3. the utility model is vdiverse in function, both can be used for it is daily give lessons, can be used for the time after school shows knowledge point.

Detailed description of the invention

Fig. 1 is the utility model hexagonal structure schematic diagram；

Fig. 2 is the utility model atmospheric pressure pole structural schematic diagram；

Fig. 3 is the utility model hexagon separate unit structural schematic diagram；

In figure, 1 is pedestal, and 2 be support rod, and 3 be adjusting rod, and 4 be divider, and 5 is write lattice, and 6 be card slot, and 7 be column Protrusion, 8 be switch bolt, and 9 be piston, and 10 be support rod lateral wall, and 11 be cylinder.

Specific embodiment

Illustrate specific embodiment of the present utility model with reference to the accompanying drawings and examples, but following embodiment only uses It is described in detail the utility model, does not limit the scope of the utility model in any way.

Unit module, components involved in following embodiment, structure, mechanism are then unless otherwise instructed routine Commercial product.

Embodiment 1: a kind of experiment device for teaching, referring to Fig. 1, the displaying cylinder including pedestal 1, support rod 2 and top；Support Bar 2 is atmospheric pressure pole, and the conventional air pressure stick produced using Anhui Lai Te company, its both ends are respectively fixedly connected in the upper of pedestal 1 Surface and the lower surface for showing cylinder；It is also equipped on support rod 2 and is used cooperatively with it to adjust the adjusting rod 3 for showing cylinder height, Show that cylinder includes with the clipboard for writing lattice 5, writing lattice 5 is english writing four lines, three lattice drawn with paint, clipboard It is write using teaching blank or green plate, blank with white board marker, green plate chalk-writing；It shows and is also evenly distributed on cylinder by applying Expect the divider 4 formed, the content to be learnt be written on the writing lattice for showing cylinder and is checked for student, it is easy to use and Normalized written.The section for showing cylinder is regular hexagon, is more suitable for writing letter, word or phonetic symbol.1 lower surface of pedestal is equipped with Idler wheel, idler wheel select the 1.5 of the production of Huizhou Kai Puao company to deposit the universal caster wheel containing brake block, can both make movement more square It just, and can the anti-sliding stop when needing fixed.Pedestal 1 and support rod 2 are stainless steel material, sturdy and durable, while its quality Also sufficiently large, it prevents from toppling over.

Fig. 2 is the structural schematic diagram of the present embodiment support rod 2, and in figure, 10 be support rod lateral wall, is internally provided with gas Cylinder 11 is filled with high pressure nitrogen in cylinder 11, and when adjusting rod 3 is pulled up, switch bolt 8 is opened, and 9 top and bottom of piston communicate, Pressure is the same, but because 9 upper end effective active area of piston is greater than lower end, active force is equal to pressure multiplied by active area, so living 9 upper end active forces are filled in greater than lower end, and cylinder 11 rises, and then makes to show that cylinder rises；When adjusting rod 3 resets, switch bolt 8 is closed It closes, piston upper end forms the confined space for being full of nitrogen, to meet the downward pressure of seat.

Embodiment 2: being substantially the same with embodiment 1, the difference is that, show that cylinder is tired out by multiple discrete cubic units Folded to form, as shown in figure 3, each cubic units upper surface is provided with card slot 6, lower surface is provided with column corresponding with card slot 6 Shape protrusion 7, using separated structure it is easy to disassemble and replacement.

The utility model is described in detail above in conjunction with drawings and examples, still, the skill of technical field Art personnel, can also be to each specific in above-described embodiment it is understood that without departing from the purpose of the present invention Parameter changes, and forms multiple specific embodiments, is the common variation range of the utility model, no longer detailed one by one herein It states.
