ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to a microphone mount, and more particularly to a structure for adjusting the position of a microphone on the microphone mount.
BACKGROUND OF THE INVENTION
As shown in
FIG. 1
, a prior art structure for adjusting the position of a microphone main body
11
comprises two lugs
15
extending from the main body
11
and having a through hole
17
, a receiving seat
19
having a threaded hole
21
and extending from a microphone mount
13
, and a fastening bolt
23
. The microphone main body
11
is adjusted mounted on the microphone mount
13
such that the two lugs
15
are mounted on the receiving seat
19
in conjunction with the fastening bolt
23
which is meshed with the threaded hole
21
via the through holes
17
of the two lugs
15
. The fastening bolt
23
has a rotary knob
25
and a shank
27
which is fitted into a spring a spring
29
. In the light of the fatigue of the spring
29
, the microphone main body
11
is apt to become slanted. In addition, the microphone main body
11
is likely to drop on the floor in the event that the fastening bolt
23
is inadvertently unfastened excessively.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a microphone mounting structure free of the drawbacks of the prior art structure described above.
In keeping with the principle of the present invention, the foregoing objective of the present invention is attained by the microphone mounting structure comprising two fastening lugs extending from the microphone main body, a receiving seat extending from a microphone mount, and a fastening member. The fastening lugs of the microphone main body is mounted on the receiving seat of the microphone mount by the fastening member. The fastening member has a threaded rod, a sleeve, and a press knob. The sleeve and the press knob are provided with ratchet teeth enabling the threaded rod to remain in the microphone main body time after time, thereby preventing the microphone main body from dropping.
The features and the advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings.
