The technical solution of the utility model includes that the oscillating bar double slider teaching aid includes a base and a vertical plate, the vertical plate is fixed on the base, the vertical plate is provided with a horizontal through slot, the horizontal through slot is provided with a horizontal slider, the vertical plate is mounted with a U-shaped oscillating bar, the U-shaped oscillating bar is connected with the vertical plate through a base pin roll, the U-shaped oscillating bar is provided with a vertical through slot, the vertical through slot is inside provided with a vertical slide, and the horizontal slider and the vertical slider are directly connected through the pin roll. The oscillating bar double slider teaching aid is simple in structure and easy to use, can be clearly demonstrate the transmission relationship between the oscillating bar and the slider, facilitate students' understanding of relevant knowledge and facilitate teacher's teaching.

Description

A kind of fork double-slider teaching aid

Technical field:

The utility model relates to the teaching aid of mechanical principle, particularly a kind of fork double-slider teaching aid of being convenient to the explanation of the drive connection between fork, the slide block.

Background technology:

Present mechanical principle teaching, if just pass through the explanation of picture and knowwhy, can not make the student be easy to understand, if can be equipped with teaching aid, model, can allow the student get more information about the relevant knowledge of mechanical principle, improved students'interest in learning greatly, also comparatively favourable to the lifting of quality of instruction.Especially the relation of being in transmission connection between fork, the slide block is used comparatively extensively, also is the chapters and sections of outbalance in the teaching, if can cooperate teaching aid, helps bigger to the student for the study of this part.

Summary of the invention:

The purpose of this utility model is that design is a kind of simple in structure, practical fork double-slider teaching aid.

The technical solution of the utility model is, a kind of fork double-slider teaching aid, it comprises base, riser, it is characterized in that: riser is fixed on the base, have horizontal groove on the riser, be equipped with cross sliding clock in the horizontal groove, at riser the U-shaped fork is installed, the U-shaped fork is connected by the base bearing pin with riser, have vertical groove at the U-shaped fork, be equipped with vertical slide block in the vertical groove, cross sliding clock directly is connected by bearing pin with vertical slide block.

The utility model is simple in structure, and is easy to use, and demonstration fork that can be more clearly and the drive connection between the slide block are convenient to the student to the understanding of relevant knowledge, have made things convenient for teacher's teaching.

Description of drawings:

Fig. 1 is structural representation of the present utility model.

Embodiment:

Describe embodiment by reference to the accompanying drawings in detail, embodiment of the present utility model is a kind of fork double-slider teaching aid, it comprises base 1, riser 2, riser are fixed on the base, have horizontal groove 6 on the riser, be equipped with cross sliding clock 5 in the horizontal groove, at riser U-shaped fork 3 is installed, the U-shaped fork is connected by base bearing pin 9 with riser, has vertical groove 4 at the U-shaped fork, be equipped with vertical slide block 8 in the vertical groove, cross sliding clock directly is connected by bearing pin 7 with vertical slide block.

The utility model is rational in infrastructure, can be along with the swing of fork, drive the movement of slide block, and can allow the student understand interaction relation between fork and the slide block intuitively; Because this device is the double-slider structure, in the process for this teaching aid, the clearance fit between each parts requires also higher simultaneously, can allow the student understand dimension chain simultaneously and calculate, and shape is the importance of tolerance and position of related features.
