Abstract

The utility model relates to a teaching demonstration table for mechanical parts, which belongs to a teaching device, comprising the model of a machine part, an inserting board and a counter. The model is fixed to the inserting board and the back surface of the inserting board is provided with inserting feet. The vertical surface of the counter is provided with a jack. The model which is required to be demonstrated is taken out from a storage tank and is inserted into the counter for carrying out demonstration. The utility model has the advantages of small ground occupying, light weight and good teaching effect.

Description

Mechanical component teaching demonstration platform

The utility model relates to a kind of teaching equipment, particularly a kind of mechanical component teaching demonstration platform.

In the mechanical major teaching of universities, technical school, vocational school, kind surplus the mechanical component that relate to have 250 for improving teaching effect, is necessary to show the mock-up of mechanical component.So prior art is fixedly mounted on these mechanical component models respectively on 20 showcases by different classes of, so that the student sees the mechanical component mock-up intuitively.The weak point that this technology exists is: 1. the showcase floor area is big, and 20 showcases always reach 25m, need take a classroom; 2. various mechanical component all place on the showcase, and unfavorable student watches the model of being showed with breathless interest; 3. showcase Heavy Weight, transportation inconvenience, cost are higher.

The purpose of this utility model provides that a kind of floor area is little, in light weight, teaching efficiency mechanical component teaching demonstration platform preferably.

The utility model structure comprises that mechanical component model (1), sales counter (3) and plate (2), model (1) are fixed on the plate (2), there is pin (2a) in groups at plate (2) back side, has on sales counter (3) facade with plate (2) to go up the jack in groups (3a) that pin (2a) is complementary.

The model (1) that is fixed on the plate (2) leaves in the storage bin, when needing to show, takes out from storage bin, inserts on sales counter (3) facade and can demonstrate.Because sales counter (3) only is one, size is suitable with the prior art showcase, and storage bin can be 5, and long is 0.7m, and height is 1.5 meters, and width and sales counter (3) are suitable, or 20 little casees, and length is 0.35m, and height is 0.75m, overlapping stacking.The total length that takes up space is about 5m like this, and floor area reduces significantly, only is 1/5～1/4 of prior art.Simultaneously, need the model of demonstration to go up demonstration at sales counter (3), and the model that need not demonstrate leaves in the storage bin, helps the model that the student observes demonstration with breathless interest, teaching efficiency is better.And sales counter (3) and storage bin general assembly (TW) reduce more than 30% than prior art, help reducing cost and make things convenient for transportation.In addition, the mechanical component model leaves in the storage bin at ordinary times, helps keeping the cleaning of model.

Fig. 1 is the utility model embodiment one front view;

Fig. 2 is left view (raising left plate) among Fig. 1;

Fig. 3 is an A-A broken section enlarged drawing among Fig. 1;

Fig. 4 is embodiment two front views.

Now in conjunction with the accompanying drawings the utility model is described in detail.The utility model structure is made up of mechanical component model (1), plate (2), sales counter (3), various mechanical component models (1) are individually fixed on the plate (2), there is pin (2a) in groups at plate (2) back side, common one group of pin is formed by four, is distributed near the top, four angles of plate (2).If plate (2) front is an oblong-shaped, pin (2a) can be distributed near the top, four angles; Also can two be distributed near the top, two angles, near two points that two are distributed in the long limit, four pins (2a) are formed square.Pin (2a) can adopt the spring inserting structure.The jack in groups (3a) that has the pin (2a) with plate (2) to be complementary on sales counter (3) facade, for rectangle plate (2), when its pin (2a) is positioned on four angles, in groups jack (3a) can be seven groups on sales counter (3) facade, wherein four groups rectangle is vertically arranged (seeing C among Fig. 1, Fig. 4), in addition three groups rectangle horizontally disposed (seeing D among Fig. 1, Fig. 4); Also can be eight groups, wherein four groups rectangle is vertically arranged, in addition four groups rectangle is horizontally disposed, and can be horizontally disposed one group one group of overlaid (see figure 1) with vertical layout, four groups of perhaps will vertically arrange respectively with four groups of horizontally disposed overlaid (see figure 4)s.Plate (2) material can be plastics, and sales counter (3) elevation material can be wood, for simplicity, adopts the metal section line to represent that it dissects the position among Fig. 3.
