Description
Technical field
The utility model relates to sound appliances technical field, particularly a kind of lowering or hoisting gear regulating microphone boom height.
Background technique
Common microphone boom comprises a base, and base is provided with an outer tube, and this outer tube is provided with pipe in, and this interior pipe is provided with a microphone clip, the sandwiched MIC microphone of this microphone clip.By the height of the lift adjustment MIC microphone of interior pipe.Lifting due to interior pipe adopts the bolt on the connecting head between outer tube and interior pipe to fix, and often bolt looseness occurs and affects fixed effect.Meanwhile, owing to being fixed by bolt between interior pipe and outer tube, interior pipe cannot rotate, and also just cannot regulate MIC microphone angle in the horizontal direction.
Model utility content
Problem to be solved in the utility model is the deficiencies in the prior art parts, provides a kind of and can stablize, reliably regulates the lowering or hoisting gear of microphone boom height, simultaneously can the angle of free adjusting MIC microphone.
The utility model is by realizing by the following technical solutions.
Manufacture and design the lowering or hoisting gear regulating microphone boom height, comprise outer tube, interior pipe and connecting head, main feature of the present utility model is: the bottom of described interior pipe is provided with round pallet, the through hole in the center of circle of described round pallet and the major diameter fit of the 3rd bearing, the described internal diameter of the 3rd bearing and the upper end of screw rod weld together, the interior threaded hole of described spiral shell worm and wheel center line coordinates, and described worm gear and worm screw engage each other, and the other end of described worm screw passes the tube wall of outer tube and is provided with and turns formula crank.
Described worm and worm wheel are contained in Worm gear case, the two ends axle journal of described worm screw respectively with the inner hole of clutch shaft bearing, the external diameter of clutch shaft bearing coordinates with the clutch shaft bearing hole on the both sides wall of Worm gear case respectively, and uses the first end cap respectively by clutch shaft bearing sealing contact on the both sides wall of Worm gear case.
The two ends end axle journal of described worm gear respectively with the inner hole of the second bearing, the external diameter of the second bearing coordinates with the second bearing hole on the both sides wall of Worm gear case respectively, and the second bearing seal is held out against on the both sides wall of Worm gear case with the second end cap respectively.
The front of described outer tube is provided with the opening for loading Worm gear case, the height dimension of opening is greater than the height dimension of Worm gear case, the width dimensions of opening is greater than the length dimension of Worm gear case, and the below of opening is provided with the support plate for install Worm gear case concordant with the lower horizontal of opening.
The center line of described support plate in the pipe of outer tube is overlapping with the center line of outer tube, the center line of support plate in the pipe of outer tube is provided with the through hole being greater than the second end cap external diameter, the outer radius portion that support plate stretches out outer tube is provided with two elongated slot through holes equal with the pitch-row in the construction bolt hole of Worm gear case.
Owing to adopting worm gear and the intermeshing structure of worm screw, on the one hand, can only drive worm gear by worm screw, worm gear can not drive worm screw, realizes the self-locking of turbine; On the other hand, worm gear can obtain accurate very little rotation, is conducive to the height of fine adjustment microphone boom.
The other end due to worm screw is provided with and turns formula crank, only need shake and turn formula crank, by the rotation of worm screw, drives the rotation with the intermeshing worm gear of worm screw.Along with the lifting of the screw rod of the screw-internal thread fit with worm gear, the lifting of pipe in realizing, thus height that is stable, that reliably regulate microphone boom.
Due to the through hole in the center of circle of round pallet and the major diameter fit of the 3rd bearing, the internal diameter of the 3rd bearing and the upper end of screw rod weld together, round pallet and interior pipe can, simultaneously in the horizontal direction in 360 ° of flexible rotatings, be convenient to regulate microphone clip and MIC microphone angle in the horizontal direction.
Front due to outer tube is provided with the opening for the corresponding size loading Worm gear case, is convenient to the installation of Worm gear case, dismounting and maintenance.The structure of support plate is then convenient to Worm gear case firmly to fix within the outer tube.
The utility model only need shake and turn formula crank, namely by the rotation of worm screw, drives the rotation of turbine, thus drives the lifting of screw rod and interior pipe, and stable, reliably to regulate microphone boom height, simultaneously can free adjusting MIC microphone angle in the horizontal direction.
