Abstract
The utility model discloses a kind of rotary joint mechanisms for microphone comprising fixed arm is connected with rotating arm on fixed arm, is cased with retaining ring on rotating arm；The other side of fixed arm is equipped with the movable plate fixed with retaining ring, and the knob that movable plate can be driven mobile；Retaining ring side is equipped with the locking ring-side wall of the thin central thick in periphery, and fixed arm is equipped with the circular groove deep with the shallow center in periphery of locking ring-side wall cooperation.The utility model is when rotating clockwise knob, knob pushes movable plate to move right, and retaining ring is driven to move right together along screw hole direction, rotating arm is in loosening state at this time, after can adjust its rotation angle, another mistake hour hands spin button drives movable plate and retaining ring to be moved to the left, retaining ring can clamp rotating arm, complete the adjustment of rotating arm angle.The utility model is easy to operate, and clamping force is big, and positioning is convenient, long service life, and rotation angle is big.
Description
[technical field]
The utility model relates to a kind of rotary joint mechanisms for microphone.
[background technique]
Microphone, scientific name are microphone, are the energy conversion devices that voice signal is converted to electric signal, by
" Microphone " this English word transliteration.Also referred to as microphone, microphone, microphone has been widely applied to people at present
In the occasion of various daily lifes, this just needs a kind of microphone that can adjust to use the microphone of height and tilt angle
Bracket.
Based on above-mentioned, the utility model people discovery, existing microphone holder is caused there are rotary joint rotation angle is small
It is inconvenient to use, it influences people and uses angle, use scope, existing microphone holder rotary joint service life when in use
It is short, it is easily damaged, having damaged just can only entirely bracket change, it causes to waste, and existing microphone holder rotary joint
Clamping force is small, can not position after rotation, is not able to satisfy the use demand of different crowd.
Then, in view of this, being studied improvement for existing structure and missing, a kind of microphone holder is provided, with
Phase achievees the purpose that with more more practical value.
[summary of the invention]
A kind of easy to operate the purpose of the utility model is to overcome providing in place of the deficiencies in the prior art, clamping force is big,
Positioning is convenient, long service life, the big microphone rotary joint mechanism of rotation angle.
Purpose of the utility model is realized as follows:
A kind of rotary joint mechanism for microphone, it is characterised in that it includes fixed arm, is flexibly connected on fixed arm
There is rotating arm, is cased with retaining ring on rotating arm；The other side of fixed arm is equipped with the movable plate fixed with retaining ring, and can drive shifting
The mobile knob of movable plate；Retaining ring side is equipped with the locking ring-side wall of the thin central thick in periphery, and fixed arm is equipped with and locking ring-side wall
The deep circular groove in the shallow center in the periphery of cooperation.
A kind of rotary joint mechanism for microphone as described above, it is characterised in that fixed arm is equipped with articulated section, circle
The side of articulated section is arranged in connected in star, and rotating arm is equipped with connecting rod, and retaining ring is socketed in connecting rod.
A kind of rotary joint mechanism for microphone as described above, it is characterised in that lead between retaining ring and movable plate
It crosses bolt to be fixedly connected, compressed spring is cased on bolt.
A kind of rotary joint mechanism for microphone as described above, it is characterised in that fixed arm is equipped with and wears for bolt
The screw hole crossed, screw hole outside are equipped with the spring card slot entered for compression Spring Card.
A kind of rotary joint mechanism for microphone as described above, it is characterised in that knob be equipped with across movable plate with
The screw rod that fixed arm is flexibly connected.
The beneficial effects of the utility model are:
For the utility model when rotating clockwise knob, knob pushes movable plate to move right, and drives retaining ring together
It moving right along screw hole direction, rotating arm is in loosening state at this time, after can adjust its rotation angle, the rotation of another mistake hour hands
Button drives movable plate and retaining ring to be moved to the left, and retaining ring can clamp rotating arm, completes the adjustment of rotating arm angle.This reality
Simple with novel operating, clamping force is big, and positioning is convenient, long service life, and rotation angle is big.
