Description

Technical Field

[0001] This utility model relates to teaching equipment, specifically to a multifunctional iron frame base building block. Background Technology

[0002] In middle school experiments, iron stands are one of the most common pieces of equipment. However, in some cases, traditional iron stands (a base + a support rod) cannot meet the needs of experimental setup. For example, when a simple pendulum experiment requires a 1-meter pendulum length, it is difficult to find an iron stand support rod longer than 1 meter. Usually, the iron stand is placed on the edge of the table, with the pendulum string extending beyond the tabletop. In this way, the center of the entire setup is prone to extending beyond the base surface, making it easy to tip over during the experiment. Similarly, in physics experiments with a double-bar coupled pendulum or in biochemistry experiments with multiple apparatus combinations, although multiple iron stands can be used, this is inconvenient. Furthermore, because the base of a traditional iron stand is relatively large, it is difficult to place the vertical rods close together (if they are too close, the bases will overlap), affecting the freedom of experimental setup.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-4 As shown, a multifunctional iron frame base block includes a number of block blocks 1 and a long rod 3 composed of multiple adjacent short rods 2 connected end to end;

[0027] The upper surface of the building block 1 is provided with tenons 11 distributed along the diagonal, while the bottom is fixedly provided with sleeves 12 corresponding to the number of tenons 11 and capable of being inserted into each other. By inserting the sleeves 12 and the tenons 11 into each other, two building blocks 1 can be stacked vertically to achieve a change in height.

[0028] Each of the four adjacent side walls of a building block 1 has two coaxially distributed through-holes 13. If each building block 1 is connected in series by passing through the through-holes 13 sequentially via a long rod 3, such as... Figure 1 As shown, this facilitates storage and management.

[0029] Furthermore, one end of the short rod 2 is a tapered threaded end 21, while the other end has a threaded connection port that connects to the tapered threaded end 21. Therefore, by removing the short rod 2, it can be inserted and combined with the sleeve 13 to form the desired shape, such as:

[0031] Figure 6 The image shows a pendulum ball experimental table.

[0032] Figure 7 The image shows a double-bar pendulum experimental platform.

[0033] Figure 8 As shown: Optical guide rod experimental platform;

[0034] Figure 9 The image shows a chemical instrumentation platform.

[0035] Furthermore, in the above embodiment, the bottom of the building block 1 has a concave structure, within which a counterweight 4 fixed to the sleeve 12 is provided. This ensures that the required shape is achieved during assembly, and the stability of the bottom prevents it from tipping over.

[0036] Furthermore, in the above embodiment, the building block 1 and the short rod 2 are made of polyethylene plastic, while the counterweight 4 is made of cast iron.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
