Table top fixing mechanism for sitting posture appliance

Abstract

The invention discloses a table top fixing mechanism for a sitting posture appliance. The table top fixing mechanism includes a base (1) and one or more supporting rods (2), the base (1) is provided with a first fixing plate (1.1) and a second fixed plate (1.2), and the supporting rods (2) penetrate through the first fixing plate (1.1); during locking, the supporting rods (2) are rotated in eitherdirection based on the position at the alpha angle to limit a locking sleeve (3) in the direction circumferentially and axially, and synchronously drive the locking sleeve (3) to be rotatably connected with a threaded hole of the first fixing plate (1.1); during releasing, the supporting rods (2) are rotated in the opposite directions, and the supporting rods (2) and the locking sleeve (3) are located on the position at the alpha angle, and the supporting rods (2) and the locking sleeve (3) slide axially. The mechanism can be quickly locked and unlocked, the tightening distance is short, andthe reliability for long-term use is better.

Description

technical field [0001] The invention relates to the technical field of sitting posture correctors, in particular to a desktop fixing mechanism of a sitting posture corrector. Background technique [0002] Current sitting posture correctors have been widely used. The sitting posture correctors generally include two parts. The upper part is structured to limit the user's writing posture, and the lower part is a base for fixing with the desktop. At present, the base all adopts long bolts to tighten and fix the desktop. The disadvantage of this fixing method is that a long-stroke rotating thread is required to clamp the desktop, which wastes time and reduces the user experience, especially for children, the strength of the arm is relatively small, which makes the operation particularly inconvenient. However, long-term use of thread tightening will also cause phenomena such as slippage, and the reliability is relatively poor. Contents of the invention [0003] The technical p...
