Description
Technical Field
[0001] The present invention relates to the technical field of educational tool technology, and in particular to a practical labor education learning tool. Background Art
[0002] With the continuous advancement of quality-oriented education, practical labor education has gradually become an important part of the basic education system. Practical labor education learning tools, as important equipment to assist teaching, are widely used in scenarios such as cultivating students' hands-on skills, project production practice, and improving their overall quality. Such tools usually have a certain operating table, support structure, and auxiliary functional devices. They can simulate various labor environments and assist in completing practical projects such as carpentry, handicraft production, and basic mechanical assembly. They play a positive role in improving students' practical skills and innovative thinking. Therefore, the development of practical labor education learning tools with reasonable structure, complete functions, and ease of use has become an important direction for the industry's technological development.
[0003] Existing practical labor education and learning tools typically utilize a fixed support structure and table design, where the operating table is supported by rigid legs. The legs are usually welded or screwed together, and rigid connectors are used to ensure structural stability. Furthermore, the operating table and supporting structure are often non-foldable or have only simple disassembly functions. Some devices can be assembled and disassembled using pins or bolts. Furthermore, the height adjustment of the supporting legs and the table angle adjustment functions are achieved through knob-type locking mechanisms and jack-type positioning mechanisms in some high-end models. The overall structure prioritizes stability and mainly meets the needs of basic teaching use.
[0004] However, existing practical labor education and learning tools have certain limitations in structural design, especially in terms of portability. Traditional devices have fixed or simply detachable legs, and the overall size is large, making them difficult to fold and store. As a result, the tools take up a lot of space when not in use, making them inconvenient to carry and transport. This is especially true in multi-venue teaching or outdoor labor teaching scenarios, where use and management are inconvenient. Therefore, there is an urgent need for a practical labor education and learning tool that can effectively be folded and stored and improve portability to better meet the actual needs of modern education for flexibility and efficiency. Summary of the Invention
[0005] In response to the deficiencies in the prior art, the present invention provides a practical labor education and learning tool, which solves the problem that practical labor education and learning tools are usually large in size and inconvenient to carry and store.
[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A practical labor education and learning tool, comprising a support plate, wherein a rotating shaft 1 is rotatably connected inside the support plate, an operating table is fixedly connected to the outer wall of the rotating shaft 1, and a folding component is provided inside the support plate;
[0007] The folding assembly includes a bidirectional threaded rod, which is rotatably connected to the inside of the support plate, one end of the bidirectional threaded rod is fixedly connected to a knob, the outer wall of the bidirectional threaded rod is threadedly connected to a symmetrically arranged threaded sleeve, the outer wall of the threaded sleeve is rotatably connected to a connecting rod 2, the inside of the support plate is rotatably connected to a rotating shaft 2, the outer wall of the rotating shaft 2 is fixedly connected to a support leg, the outer wall of the support leg is fixedly connected to a rotating shaft 3, and one end of the connecting rod 2 is rotatably connected to the outer wall of the rotating shaft 3.

[0019] When the operating table needs to be unfolded, the operating table is connected to the support plate through the support rod. Then, after the arc rod is unfolded, the operating table is driven to rotate with the rotating shaft as the center by the handle. The support rod is slid and limited in the arc groove by the cross rod. After it is in place, the fastening bolts are tightened to fix the operating table in the specified position in the arc rod, thereby achieving the effect of facilitating the adjustment of the support angle.
[0020] The present invention provides a practical labor education learning tool with the following beneficial effects:
[0021] 1. The present invention first drives the threaded sleeve to slide on the outer wall of the two-way threaded rod, and then the threaded sleeve drives the legs to be stored inside the support plate through the second connecting rod, so as to achieve the effect of folding and storing teaching tools, solve the problem that practical labor education and learning tools are usually large in size and inconvenient to carry and store, and improve the portability of practical labor education and learning tools.
[0022] 2. The extension leg of the present invention is inserted into the interior of the support leg through the connecting column, so that the locking column inside the support leg is embedded in the locking groove to lock the extension leg, thereby achieving the effect of facilitating the extension of the height, solving the problem of inconvenient operation for users of different usage conditions or different heights, and improving the practicality of practical labor education and learning tools.
[0023] 3. The handle of the present invention drives the operating table to rotate with the rotating shaft as the center. The support rod is slidably limited in the arc groove by the cross rod. After it is in place, the fastening bolts are tightened to fix the operating table at the specified position in the arc rod, thereby achieving the effect of facilitating the adjustment of the support angle, solving the problem that the support plate has a single angle and is inconvenient to use during labor teaching, and improving the convenience of practical labor education learning tools.
