Microphone rotating joint mechanism

Abstract

The invention discloses a microphone rotating joint mechanism, which comprises a fixed arm, a rotating arm is movably connected to the fixed arm, and a locking ring is sleeved on the rotating arm; A movable plate fixed with the locking ring and a knob capable of driving the movable plate to move are arranged on the other side of the fixed arm; A locking ring side wall with the periphery thin and the center thick is arranged on one side of the locking ring, and a round groove with the periphery shallow and the center deep is formed in the fixing arm and matched with the locking ring side wall.When the knob is rotated clockwise, the knob is rotated clockwise; The knob pushes the moving plate to move rightwards and drives the locking ring to move rightwards in the direction of the screw hole, at the moment, the rotating arm is in a loose state, after the rotating angle of the rotating arm can be adjusted, the button is rotated anticlockwise, the moving plate and the locking ring are driven to move leftwards, the locking ring can clamp the rotating arm, and the angle of the rotating arm is adjusted. The clamping device is easy to operate, large in clamping force, convenient to position, long in service life and large in rotation angle.

Description

【Technical field】 [0001] The invention relates to a microphone rotary joint mechanism. 【Background technique】 [0002] Microphone, scientifically called microphone, is an energy conversion device that converts sound signals into electrical signals. It is transliterated from the English word "Microphone". Also known as microphones and microphones, microphones have been widely used in people's various daily life occasions at present, which requires a microphone stand that can adjust the height and inclination angle of the microphone. [0003] Based on the above, the inventors found that the existing microphone holder has a small rotation angle of the rotary joint, which causes inconvenient use and affects people's use angle and range of use. The existing microphone holder's rotary joint has a short service life and is easily damaged. If it is damaged, the entire bracket can only be replaced, resulting in waste. Moreover, the clamping force of the rotating joint of the existin...

[0003] Based on the above, the inventors found that the existing microphone holder has a small rotation angle of the rotary joint, which causes inconvenient use and affects people's use angle and range of use. The existing microphone holder's rotary joint has a short service life and is easily damaged. If it is damaged, the entire bracket can only be replaced, resulting in waste, and the clamping force of the rotating joint of the existing microphone bracket is small, and it cannot be positioned after rotation, which cannot meet the needs of different groups of people.
