Abstract
The invention discloses a microphone rotary joint mechanism, which comprises a fixed arm, wherein a rotary arm is movably connected to the fixed arm, and a locking ring is sleeved on the rotary arm; the other side of the fixed arm is provided with a moving plate fixed with the locking ring and a knob capable of driving the moving plate to move; the locking ring is provided with a locking ring side wall with a thin periphery and a thick center, and the fixing arm is provided with a circular groove with a shallow periphery and a deep center which is matched with the locking ring side wall. When the knob is rotated clockwise, the knob pushes the movable plate to move rightwards and drives the locking ring to move rightwards along the screw hole direction, 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 movable plate and the locking ring are driven to move leftwards, and the locking ring can clamp the rotating arm to complete the adjustment of the angle of the rotating arm. The invention has the advantages of simple operation, large clamping force, convenient positioning, long service life and large rotation angle.
Description
[ field of technology ]
The present invention relates to a microphone rotary joint mechanism.
[ background Art ]
The Microphone, known as a Microphone, is an energy conversion device for converting sound signals into electrical signals, and is transliterated by the english word "Microphone". Also called a microphone and a microphone, the microphone is widely applied to various occasions of daily life, and a microphone bracket capable of adjusting the use height and the inclination angle of the microphone is needed.
Based on the above, the present inventors found that the rotation angle of the rotation joint of the existing microphone bracket is small, which causes inconvenient use, affects the use angle of people in use, and the use range of the existing microphone bracket, and the rotation joint of the existing microphone bracket has short service life and is easy to damage, so that the existing microphone bracket can only be replaced by the whole bracket, thereby causing waste.
Accordingly, in view of the above, research and improvement are made to the existing structure and the existing defects, and a microphone stand is provided to achieve the purpose of having more practical value.
[ invention ]
The invention aims to overcome the defects of the prior art and provide the microphone rotary joint mechanism which is simple to operate, high in clamping force, convenient to position, long in service life and large in rotation angle.
The purpose of the invention is realized in the following way:
the microphone rotary joint mechanism is characterized by comprising a fixed arm, wherein the fixed arm is movably connected with a rotary arm, and the rotary arm is sleeved with a locking ring; the other side of the fixed arm is provided with a moving plate fixed with the locking ring and a knob capable of driving the moving plate to move; the locking ring is provided with a locking ring side wall with a thin periphery and a thick center, and the fixing arm is provided with a circular groove with a shallow periphery and a deep center which is matched with the locking ring side wall.
The microphone rotary joint mechanism is characterized in that the fixed arm is provided with the pivoting part, the circular groove is arranged on one side of the pivoting part, the rotating arm is provided with the connecting rod, and the locking ring is sleeved on the connecting rod.
The microphone rotary joint mechanism is characterized in that the locking ring is fixedly connected with the movable plate through the bolts, and the compression springs are sleeved on the bolts.
The microphone rotary joint mechanism is characterized in that the fixed arm is provided with a screw hole for a bolt to pass through, and the outer side of the screw hole is provided with a spring clamping groove for a compression spring to clamp in.
The rotary joint mechanism of the microphone is characterized in that the knob is provided with a screw rod which penetrates through the movable plate and is movably connected with the fixed arm.
The beneficial effects of the invention are as follows:
when the knob is rotated clockwise, the knob pushes the movable plate to move rightwards and drives the locking ring to move rightwards along the screw hole direction, 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 movable plate and the locking ring are driven to move leftwards, and the locking ring can clamp the rotating arm to complete the adjustment of the angle of the rotating arm. The invention has the advantages of simple operation, large clamping force, convenient positioning, long service life and large rotation angle.

[ detailed description ] of the invention
The invention is further described below with reference to the accompanying drawings:
a microphone rotary joint mechanism comprises a fixed arm 1, wherein a rotary arm 2 is movably connected to the fixed arm 1, and a locking ring 3 is sleeved on the rotary arm 2; the other side of the fixed arm 1 is provided with a movable plate 4 fixed with the locking ring 3 and a knob 5 capable of driving the movable plate 4 to move; the locking ring 3 is provided with a locking ring side wall 31 with a thin periphery and a thick center, and the fixing arm 1 is provided with a circular groove 11 with a shallow periphery and a deep center which is matched with the locking ring side wall 31. When the knob 5 is rotated clockwise, the knob pushes the moving plate 4 to move rightwards, the locking ring 3 is driven to move rightwards along the direction of the inclined hole, the rotating arm 2 is in a loose state at the moment, after the rotating angle of the rotating arm can be adjusted, the button 5 is rotated anticlockwise, the rotating arm can be clamped, and the angle adjustment of the rotating arm 2 is completed.
The fixed arm 1 is provided with a pivoting part 10, a circular groove 11 is arranged on one side of the pivoting part 10, the rotating arm 2 is provided with a connecting rod 20, and the locking ring 3 is sleeved on the connecting rod 20.
The locking ring 3 is fixedly connected with the movable plate 4 through a bolt 6, and a compression spring 7 is sleeved on the bolt 6. The number of bolts 6 may be one or more, and the number of springs 7 is equal to the number of bolts 6, so that the movable plate 4 can be reset more quickly.
The fixed arm 1 is provided with a screw hole 12 for the bolt 6 to pass through, and a spring clamping groove 13 for the compression spring 7 to be clamped in is arranged outside the screw hole 12.
