Machine etc. has the equivalent product of sound source acquisition on the market, installs restricted sound source between the second suspension arm 9b and third suspension arm 9c
The position-limit mechanism 12 of 10 hunting range of acquisition device.
It further illustrates, referring to Fig. 3, position-limit mechanism 12 includes connecting rod 121 and fixed pin 123, and the second suspension arm 9b is close
One end of third suspension arm 9c is rotatably connected to connecting rod 121, and fluting 122 is offered on connecting rod 121, is welded on third suspension arm 9c
There is the fixed pin 123 being slidably connected in fluting 122.The effect of position-limit mechanism 12 is, is acquired by connecting rod 121 to sound source
Device 10 carries out lateral support and fixation, to prevent sound source acquisition device 10 from occurring by a relatively large margin under the action of extraneous wind-force
Swing, and compensation is played the role of in 122 setting of slotting, thus between adjusting the second suspension arm 9b and the first suspension arm 9a
When angle, the angle between sound source acquisition device 10 and third suspension arm 9c can be changed correspondingly, and 122 setting of slotting can prevent card
Extremely.
The present invention using when push pedestal 1 to move under the action of bottom traveling wheel 2 by pushing hands 13, it is suitable to be moved to
Behind position, it can be braked by the installation rubber brake pad on traveling wheel 2.
Then the balance that pedestal 1 is realized by load-bearing device 14, prevents its inclination: manually rotating screw thread by handle 142
Outer cylinder 141, screw thread outer cylinder 141 drives the screw thread inner cylinder 143 being threadedly coupled therewith to move downward, so that sucker 144 contacts to earth
And compress, since sucker 144 is elastic component, thus when its elasticity recovery, can to build subnormal ambient in its, it can be extraneous big
The balance of realization device ontology under the action of air pressure is strong, and due to the length limit of weight bearing mechanism 14, it is not in that device is past negative
The case where 14 side of heavy-duty machine structure tilts.
Then adjust the height of sound source acquisition device 10: artificial 5 rotating shaft 6 of isomorphism rotating handles, shaft 6 pass through transmission
Mechanism 7 passes torque to screw rod 4, and screw rod 4 drives the link block 8 being threadedly coupled therewith to move up and down, to realize height
It adjusts.
The length that sound source acquisition device 10 can further be adjusted is adjusted to after suitable height: artificial by 113 turns of knob
Dynamic nut 112, nut 112 drive the screw rod 114 being threadedly engaged therewith to be axially moved, and realize the suspension of the first suspension arm 9a and second
Arm 9b is close to each other or far from movement, i.e., the reduction of suspension arm lateral distance is realized by the extension of suspension arm longitudinal direction height, most
It realizes that sound source acquisition is located at the top head of performer with record device afterwards, realizes the acquisition of sound source.
