Embodiment Construction
[0011] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0012] The structure of the telescopic foldable iron stand involved in the present invention consists of figure 1 As shown, the iron frame platform given above mainly consists of a three-stage telescopic rod, a double-layer base, and a long bolt with a clip. The specific composition of each part consists of Figure 2 to Figure 4 as shown, figure 2 A schematic diagram of the structure of the three-stage telescopic rod is given. The telescopic rod shown in the figure is composed of three hollow metal tubes with different diameters. The length can be determined according to the needs. Nesting from small to large, the telescopic rod I is inserted into the telescopic rod II, and the telescopic rod II is inserted into the telescopic rod III, a...

The invention discloses a telescopic foldable iron support stand which mainly comprises a telescopic link, a clip and a base. The telescopic link comprises a plurality of hollow tubes which are nested together sequentially, the upper end of each hollow tube is provided with a locating device, and the upper end of the telescopic link is provided with a small hole; the clip is formed by connecting a bolt and an iron support stand, and the bolt is provided with stop nuts; the base consists of an upper base and a lower base, one side of the upper base is movably connected with the lower base, and the opposite of the side is connected with the lower base by the locating device; and the lower end of the telescopic link is fixedly connected with the upper base, the bolt passes through the small hole at the upper end of the telescopic link, and the length is controlled by the stop nut on the bolt. The iron support stand obtained by the technical proposal can achieve the telescopic movement and folding movement of the whole iron support stand conveniently, the operation of the stand is realized conveniently and simply, and the storage is convenient.
Description
Technical field: [0001] The invention relates to a physics teaching tool, in particular to a multi-section, telescopic and foldable iron stand. Background technique: [0002] In the past, the iron stand in the physics laboratory was a unified form of iron stand made of iron with a height of about half a meter. It is very unsightly and unsafe to put the chair on the desk for operation, such as the simple pendulum experiment; the commonly used iron stand is also very inconvenient in storage and takes up a lot of space. Invention content: [0003] The present invention aims at the deficiencies and defects of the above-mentioned existing iron stand, and provides an iron stand that can be freely stretched and folded, and is convenient for operation and storage. [0004] In order to achieve the above object, the iron frame platform provided by the present invention mainly includes a telescopic rod, a clip and a base. The telescopic rod is composed of a plurality of hollow tubes...
