Embodiment Construction

[0016] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0017] like figure 1 , figure 2 and image 3 As shown, the present invention includes an outer cylinder 1 and an inner cylinder 2, both of which are hollow structures and have polygonal cross-sections, and the inner cylinder 2 is arranged on the outer cylinder. In the middle part of the body 1 , the inner cylinder 2 and the outer cylinder 1 are fixedly connected by reinforcing ribs 3 .

[0018] In this embodiment, the reinforcing rib 3 is a strip-shaped plate structure, the outer edge of the reinforcing rib 3 is welded to the inner wall of the outer column 1 , and the inner edge of the reinforcing rib 3 is welded to the outer wall of the inner column 2 . The cross-section of the outer cylinder 1 is an octagonal structure, the cross-section of the inner cylinder 2 is a regular quadrilateral with a side length of 31.6 mm, and the maximum vertical distance between t...

Abstract

The invention discloses a special multi-edge double-layer upright post for an experiment table. The special multi-edge double-layer upright post comprises an outer post body and an inner post body, wherein the outer post body and the inner post body are of hollow structures, and the cross sections of the outer post body and the inner post body are of polygonal structures; the inner post body is arranged in the middle inside the outer post body; and the inner post body and the outer post body are fixedly connected by virtue of reinforcing ribs. The special multi-edge double-layer upright post disclosed by the invention is a multi-edge hollow post with the inner and outer layers, the superficial area is large, and the reinforcing ribs achieve the inwards longitudinal and transverse supporting effects. Therefore, the upright post is high in strength, low in damage rate and long in service life.

Description

technical field [0001] The invention relates to the technical field of teaching equipment, in particular to a special multi-edge double-layer column for an experiment table. Background technique [0002] At present, the supporting frame used for the laboratory table body table frame in teaching equipment is generally Figure 4 The cylindrical structure made of aluminum alloy is shown, and a card slot is set on it for the card MDF, but the surface area of ​​this structure is small, it is a single-layer hollow tube, and it lacks vertical and horizontal internal support, so that the strength is poor and the damage rate is low. High and short service life. Contents of the invention [0003] The object of the present invention is to provide a special multi-edge double-layer column for the experiment table in order to solve the above problems. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A multi-edge do...
