Embodiment

Describe the utility model in detail below with reference to accompanying drawing and in conjunction with the embodiments.It should be noted that not conflicting In the case of, the feature in embodiment and embodiment in the utility model can be mutually combined.For sake of convenience, hereinafter such as There are " on ", " under ", "left", "right" printed words, only represent that the upper and lower, left and right direction with accompanying drawing in itself is consistent, not to structure Play restriction effect.

Please refer to Fig. 1 and Fig. 2, wherein, the structure for the Applied Writing demonstration teaching aid that Fig. 1 provides for the utility model Schematic diagram, Fig. 2 is Fig. 1 vertical view partial cutaway schematic diagram.The Applied Writing demonstration teaching aid includes support frame 1, underframe 2, divided Dividing plate 3, demonstration frame 4, demo rack 5, rotating shaft 6, control box 7, motor 8 and amplification mirror assembly 9.

The quantity of support frame as described above 1 is two, is horizontally spaced about.The underframe 2 is located at the bottom of support frame as described above 1. The demarcation strip 3 is vertically arranged, and its quantity is multiple, and multiple demonstration frames 4 are formed with support frame as described above 1.Drilled described in each Show and demo rack 5 is equipped with frame 4, the longitudinally disposed rotating shaft 6 in inside of each demo rack 5, the rotation of the rotating shaft 6 passes through electricity Machine 8 is driven, and the motor 8 is electrically connected with control box 7, and the behaviour that manipulation demo rack 5 is rotated forward and overturn is provided with the control box 7 Make button 71.

The demarcation strip 3 is vertically provided with a chute 31, and the chute 31 is the rectangular slot of insertion, thereafter side For plane 311, leading flank is step trough 312 (leading flank is the one side for closing on student, otherwise is trailing flank).

In the present embodiment, the quantity of the demarcation strip is 2 multiple, according to the demonstration frame 4 of actual use come fixed specific Quantity.

The amplification mirror assembly 9 is set up in the demonstration frame 4 between demarcation strip 3 described in each two, the magnifying glass Component 9 is located at the front end of the demo rack 5.The amplification mirror assembly 9 includes magnifying glass 91, card and sets mechanism 92 and sliding equipment 93。

The magnifying glass 91 is in the front end of demo rack 5, for amplifying the practical writing that patch is shown on demo rack 5.The amplification The height dimension of mirror 91 is less than the height dimension of demonstration frame 4, and local enlargement display of withdrawing deposit facilitates student to concentrate on a certain position and seen Demo content is seen, targetedly, is improved learning efficiency.

The card sets the quantity of mechanism 92 as two, is respectively arranged at the both sides of magnifying glass 91.The card sets mechanism 92 and existed Magnifying glass 91 is set up between demarcation strip 3 in the chute 31.

The card, which sets mechanism 92, includes spring 921 and button 922.The spring 921 is stage clip, is connected to the magnifying glass Between 91 and button 922.

The section of the button 922 is stepped, and it includes folded the first cascaded surface 9221 and the second cascaded surface 9222 set. The face that the chute 31 is contacted with magnifying glass 91 is the plane 311, and the face that the chute 31 is contacted with button 922 is the rank Terraced groove 312.First cascaded surface 9221 is abutted with step trough 312, and first cascaded surface 9221 is provided with a rubber layer, can To increase frictional force, first cascaded surface 9221 is fitted with step trough 312 closer, can consolidate preferably in chute 31 Determine the position of magnifying glass 91.Second cascaded surface 9222 is provided with a groove 9223, and the surface of the groove 9223 is frosted Layer, it is non-slip when facilitating finger pressing operation, and quick position movement is carried out to magnifying glass 91.

The sliding equipment 93 on the magnifying glass 9 away from it is described block set the side of mechanism 92, and with chute 31 The plane 311 abuts formula connection, for reducing the force of sliding friction that magnifying glass 91 is produced in chute 31.

In the present embodiment, the sliding equipment 93 is the ball for being embedded into magnifying glass 91, and the quantity of the ball is many Individual, it is arranged at intervals on the vertical direction of magnifying glass 91.

The quantity of the amplification mirror assembly 9 is identical with the quantity for demonstrating frame 4, i.e., being provided with one in each demonstration frame 4 drills Show frame 5 and amplification mirror assembly 9.

Refer to the structural representation that Fig. 3 is pressed for button in Fig. 2.The Applied Writing demonstration that the utility model is provided The demenstration method of teaching aid is：

Ready Applied Writing model essay is fixed on the demo rack 5, will when needing to demonstrate certain partial content The magnifying glass 91 is moved to the part, is specially：Finger is pinned the position of groove 9223 of both sides button 922 and pressed simultaneously, First cascaded surface 9221 and the step trough 312 of the button 922 depart from, and the spring 921 is compressed, the sliding equipment 93 ball abuts the plane 311, and finger drags the button 922 and just moved in the chute 31 while pressing Dynamic, ball is rolled in the plane 311, reduces the power moved to magnifying glass 91.

When the magnifying glass 91 is moved to the position of needs, the button 922 is unclamped, in the effect of the spring 921 Under, first cascaded surface 9221 is abutted again with step trough 312, in the presence of the rubber layer of the first cascaded surface 9221, closely Laminating, the position of the magnifying glass 91 is just fixed.

Thus repeatedly, the amplifications of different demo contents is realized.Demonstrated piece by piece, with strong points, learning efficiency is high.

The stroke and direction that the magnifying glass 91 is moved are relevant with chute 31, the length of the step trough 312 of the chute 31 Equal to the adjustable distance of the vertical direction of magnifying glass 91.

Embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, it is every The equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or be directly or indirectly used in Other related technical fields, are similarly included in scope of patent protection of the present utility model.
