Specific embodiment
Below in conjunction with attached drawing, the technical scheme in the utility model embodiment is clearly and completely described.
Referring to figs. 1 to Fig. 4, the embodiments of the present invention propose a kind of lapel mike rack joint mechanism, including
Fixing seat 1 and rotating member 3, the rotating member 3 has pivot block 30 and is pivotally connected by the pivot block 30 with fixing seat 1, described
It is equipped with the fixing piece 2 fixed with the fixing seat 1 in pivot block 30, is formed between the fixing piece 2 and pivot block 30 tapered logical
Road 4 is provided with rolling member 5 in the tapered channels 4, elastic component 6 is additionally provided between the fixing piece 2 and rolling member 5, described
When rotating member 3 rotates counterclockwise, the rolling member 5 is rolled by the elastic force driving of elastic component 6 towards the narrow one end of tapered channels 4
It moves until, whereby with rotating member 3 and fixing seat 1 is fixed, the rotating member 3 is clockwise by 30 clamping of fixing piece 2 and pivot block
When rotation, the rolling member 5 is driven by rotating member 3 and is rolled towards the wide one end of tapered channels 4 so that the rotating member 3 can be protected
Hold rotation.
In the present embodiment, the pivot block 30 is cylindrical, and the fixing piece 2 is in round pie, the side of the fixing piece 2
Jagged 21 are opened up, the tapered channels 4 are surrounded by the inner wall of the notch 21 and pivot block 30.The outside of the pivot block 30
It is provided with outwardly extending cursor 31 on wall, outwardly extending fixed arm 13 is provided in the fixing seat 1.
Referring to Fig. 4, when rotating member 3 rotates clockwise, rotating member 3 can drive rolling member 5 to the frictional force of rolling member 5
One end wide towards tapered channels 4 rolls, since tapered channels 4 are gradually expanded in this direction, turn as long as can overcome
Frictional force between moving part 3 and rolling member 5, so that it may optionally rotating member 3 be driven to rotate clockwise；Rotating member 3 turns counterclockwise
When dynamic, rolling member 5 is driven jointly by the elastic force and 3 frictional force of rotating member of elastic component 6 and is rolled towards narrow one end of tapered channels 4
It is dynamic, due to the gradually constriction of tapered channels 4 in this direction, it rolls after certain stroke (the trip is generally less than 1mm),
Rolling member 5 will be clamped between rotating member 3 and notch 21, whereby with rotating member 3 and fixing piece 2 is fixed.Referring to Fig. 5, make
When with the utility model, fixed arm 13 is fixedly connected with bracket 7, and cursor 31 is fixedly connected with microphone 8, and microphone 8 answers position
In the left side of fixed arm 13, rotating member 3 can be locked under the action of the gravity of microphone 8 at this time；If microphone 8 is located at
The right side of fixed arm 13, rotating member 3 may then be rotated clockwise by the gravity drive of microphone 8.It is with the state in Fig. 5
Example, when needing to increase the height of microphone 8, driving rotating member 3 rotates clockwise a lesser angle, needs to reduce Mike
When the height of wind 8, then need the rotation of driving rotating member 3 with biggish angle, so that microphone 8 bypasses its highs and lows,
Until microphone 8 is located at the left side of fixed arm 13.
Referring to Fig. 2 and Fig. 3, the fixing seat 1 is plate-like and is located at the side of pivot block 30, the side of the fixing seat 1
It is additionally provided with the central axis 11 extended in pivot block 30, the fixing piece 2 is set on the central axis 11 and by a positioning
Pin 9 and the central axis 11 are fixed.The limit plate that restricted rotating member 3 moves axially is arranged in the other side of the pivot block 30
12, the limit plate 12 is spirally connected with the central axis 11.
Fixing seat 1 and fixing piece 2 can be split type structure, be also possible to integral structure.Rolling member 5 is that shape can be with
It is the revolution shape such as cylinder, spherical shape, circle drum, truncated cone-shaped.Elastic component 6 can be spring, be also possible to the bullets such as elastic slice, torsional spring
