Brake mechanism easy to install and lifting stand column adopting brake mechanism

Abstract

The invention relates to a brake mechanism easy to install, which comprises a first connecting piece, an installation seat and a second connecting piece, the installation seat is provided with an inner ring wall, the second connecting piece is limited on the inner ring wall, and the first connecting piece can partially penetrate through the inner ring wall and is fixedly connected with the second connecting piece to form a whole to be installed in a box body. And the mounting seat and the box body are kept static, and the first connecting piece and the second connecting piece synchronously and circumferentially rotate relative to the mounting seat. The invention further relates to a lifting stand column which comprises an inner pipe assembly, a middle pipe assembly, an outer pipe assembly and a driving pipe, one end of the inner pipe assembly is connected with a box body, a driving motor and a transmission mechanism are arranged in the box body, the braking mechanism is arranged on the box body, the transmission mechanism is connected with the first connecting piece, and the driving pipe is matched with the second connecting piece. The problems of lifting shaking, motor efficiency, brake structure detection and rapid assembly caused by inconsistent damping of two or more lifting table legs in operation are solved.

Description

technical field [0001] The invention relates to the technical field of lifting columns, in particular to a braking mechanism for easy installation and a lifting column using the braking mechanism. Background technique [0002] The automatic lifting table is generally powered by electricity, and the height of the lifting table is adjusted by controlling the mechanical device through the motor, or the height of the lifting table can be adjusted by controlling the air pressure rod or the hydraulic rod through the compressor. This type of lifting table has single-column and double-column forms, and there are two lifting methods: remote control and manual control. The automatic lifting table needs a reliable self-locking mechanism in actual use, so that it will not slide down. [0003] The patent with the notification number CN210265590U discloses a friction self-locking mechanism for lifting columns, including friction parts and connecting parts. The friction parts and connecti...

Problems solved by technology

The disadvantages of this patent are also the complex structure and inconvenient installation. Although it provides one-way friction, it is difficult to make the resistance values ​​of the two lifting columns close to each other when starting, which is easy to cause shaking

[0006]Therefore, the technical problems that need to be solved are: 1. When two or more lifting columns are started, if the lifting resistance is not close to the same, it will cause the vibration of the lifting table; 2. .The resistance value of the existing friction structure increases in proportion to the load, resulting in excessive loss of drive motor efficiency; 3. The existing braking mechanism must be installed from two directions of the box body, and it is impossible to detect whether the assembled braking mechanism is 4. The vibration of the motor itself is transmitted to the lifting column through the connecting parts, resulting in increased vibration
