Locking mechanism for tubular vertical rod and tubular vertical rod device employing locking mechanism

Abstract

The invention relates to a locking mechanism for a tubular vertical rod. The locking mechanism comprises a pair of screws and a locking combination block which is correspondingly matched with the screws, wherein the locking combination block comprises two locking blocks and an elastic piece which is positioned between the two locking blocks and used for applying opposite acting forces to the two locking blocks; a screw hole which is in screwed fit with the screw is formed in each locking block; and each locking block is provided with an arc surface which is complementary to the inner wall of the tubular vertical rod in shape and tightly attached to the inner wall of the tubular vertical rod. The invention also relates to a tubular vertical rod device. The opposite rod walls of the tubular vertical rod and two supporting arms of a base are rigidly fixed together respectively by the locking mechanism, so the problem of deformation of the tubular vertical rod caused by extrusion can be solved, and the problem of loosening caused by non-tight attachment of the supporting arms to the tubular vertical rod due to the deformation of the tubular vertical rod can be solved. An effect of fixing the tubular vertical rod is good, damage to the tubular vertical rod device can be avoided, and the service life of the tubular vertical rod device is greatly prolonged.

Description

technical field [0001] The invention relates to a locking mechanism, in particular to a locking mechanism for a tubular vertical rod, and also relates to a tubular vertical rod device with the locking mechanism. Background technique [0002] In engineering applications, the pitch-adjustable pole brings great convenience to installation, commissioning and maintenance, but at the same time, whether it can be fixed conveniently, quickly, safely and reliably has become a very critical issue. [0003] Current tubular pole devices such as figure 1 , 2 As shown, it generally includes a base 3 with two arms 4 and a tubular vertical rod 1 whose lower end is located between the two arms 4 and fixed on the support arms 4. The tubular vertical rod 1 is fixed on the support by a locking mechanism. On the arm 4, the locking mechanism is two long bolts 2, the two long bolts 2 are distributed along the axial direction of the tubular vertical rod 1 and pass through the tubular vertical rod...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a locking mechanism for a tubular vertical pole, to solve the problem that the locking mechanism in the prior art is not effective in fixing the tubular vertical pole, and is easy to cause damage to the tubular vertical pole device and shorten the service life. A tubular pole device using the locking mechanism is provided
