Description

Technical Field

[0001] The utility model relates to the technical field of support columns, in particular to a freely adjustable lifting support column. Background Art

[0002] Material platforms are various temporary operating tables and operating frames often set up at construction sites, generally used for material turnover. Material platforms are divided into mobile material platforms, floor-standing material platforms, and cantilevered material platforms.

[0003] At present, floor-standing material platforms are generally used as material storage platforms for enterprises. Sometimes, a temporary material platform needs to be built. During construction, the platform is generally required to be flat, but the ground on which it is built may be uneven. Therefore, support columns need to be placed under the material platform. The flatness of the material platform can be ensured by adjusting the height of the support columns. However, the existing support columns are time-consuming, labor-intensive, and inconvenient to adjust.

[0004] In view of the fact that the existing support columns are time-consuming, labor-intensive and inconvenient to adjust, a freely adjustable lifting support column is urgently needed to solve the above problems. Summary of the Invention

[0005] Aiming at the situation that the existing support columns are time-consuming, labor-intensive and inconvenient to adjust, the utility model proposes a freely adjustable lifting support column to solve the above problems.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is a freely adjustable lifting support column, including a sleeve, an insertion rod is inserted into the upper part of the sleeve, an adjustment ring is threadedly connected to the outer side of the insertion rod, and the bottom of the adjustment ring abuts against the top of the sleeve. When in use, by rotating the adjustment ring, the bottom of the adjustment ring abuts against the top of the sleeve, causing the insertion rod to move upward, thereby realizing height adjustment of the insertion rod. The overall structure of the support column is simple, easy to use, and suitable for popularization and use.

[0007] Furthermore, a scale bar is provided on the outside of the insertion rod, and the adjustment height can be determined by the scale bar, so that multiple support columns can be adjusted together, which is more convenient to use.

[0008] Furthermore, an annular groove is provided in the middle of the outer side of the adjusting ring, and a clamping groove is provided on the lower side wall of the annular groove, through which the extension tool can be clamped, so that the staff can rotate the adjusting ring.

[0009] Furthermore, a mounting seat is fixed on the outside of the sleeve, and a limit hook is hinged on the mounting seat. One end of the limit hook is engaged with the engaging groove. By engaging one end of the limit hook with the engaging groove, the adjustment ring can be prevented from rotating after the adjustment is completed. At the same time, the insertion rod can be prevented from detaching from the sleeve during transportation.

[0010] Furthermore, a spring is provided between the limiting hook and the sleeve, and both ends of the spring are connected to the limiting hook and the sleeve respectively, so that the limiting hook can be prevented from being separated from the engaging groove by the spring.

[0011] Furthermore, there are at least two snap-fitting slots, which are distributed in a ring shape, and all the snap-fitting slots are evenly spaced apart.

[0012] The beneficial effects of the utility model are:

[0013] The support column has a simple overall structure and is easy to adjust. One end of the limit hook is engaged with the card slot to prevent the adjustment ring from rotating after the adjustment is completed. At the same time, it can prevent the insertion rod from detaching from the sleeve during transportation. The overall use effect is good and the practicality is strong.
