Detailed Description

Referring to fig. 1-5, the present invention provides a technical solution: the utility model provides a podium of liftable, including lift podium 1, recess 2 has been seted up at lift podium 1's top, connecting groove 14 has been seted up to recess 2's diapire, the 2 internal rotations in recess are connected with first pivot 3, the fixed surface of first pivot 3 is connected with gear 4, the fixed surface of first pivot 3 is connected with ratchet 10, ratchet 10 is located gear 4's rear side, recess 2's back wall rotates and is connected with second pivot 11, the fixed surface of second pivot 11 is connected with pawl 12, the rear side of second pivot 11 extends to lift podium 1's rear side, first torsion spring 13 has been cup jointed in the surface activity of second pivot 11, the front side fixed connection of first torsion spring 13 is at lift podium 1's rear side, the rear side fixed connection of first torsion spring 13 is on the surface of second pivot 11.

Gear 4's left side meshing is connected with pinion rack 5, the top fixedly connected with microphone 9 of pinion rack 5, pinion rack 5 is at

spread groove

14 and 2 sliding connection in recess, pinion rack 5 slides from top to bottom in spread groove 14 and recess 2, microphone 9 is at 2 sliding connection in recess, microphone 9 slides from top to bottom in recess 2, spout 7 has been seted up to recess 2's left wall, 7 sliding connection in spout has slider 6, slider 6 slides from top to bottom in spout 7, spout 7 is cylindric and identical with slider 6's cross sectional shape, slider 6's diameter is less than the diameter of spout 7 but can't break away from in spout 7, and then restrict slider 6's effectual moving range through spout 7, guarantee slider 6's mobility stability, slider 6's right side and pinion rack 5's left side fixed connection, fixedly connected with spring 8 between slider 6's the bottom and the diapire of spout 7.

When the microphone 9 is not used, the microphone 9 needs to be stored into the groove 2, in a static state, under the elastic force action of the first torsion spring 13, the ratchet 12 is located in teeth of the ratchet 10 and blocks the ratchet 10 in the left rotation direction, the sliding block 6 is located at the topmost part of the sliding groove 7 at the moment, the spring 8 is in a stretching state, the elastic force of the first torsion spring 13 is larger than that of the spring 8, when the microphone 9 needs to be stored, the second rotating shaft 11 is rotated, the second rotating shaft 11 rotates to drive the first torsion spring 13 to rotate and deform, meanwhile, the second rotating shaft 11 rotates to drive the ratchet 12 to rotate and disengage from teeth of the ratchet 10, at the moment, under the elastic force action of the spring 8, the sliding block 6 moves downwards to drive the toothed plate 5 and the microphone 9 to move downwards, the microphone 9 moves downwards to contract into the groove 2, the toothed plate 5 moves downwards to drive the gear 4 to rotate, the gear 4 rotates to drive the first rotating shaft 3 to rotate to drive the ratchet 10 to rotate, after the microphone 9 is fully contracted into the groove 2, the movement of the ratchet 11 is stopped, the ratchet 13 returns to the second torsion spring 12, and the spring 13 returns to the elastic force action.

Through rotating second pivot 11 and finally making acanthosis 12 no longer block ratchet 10, under the spring action of spring 8, finally make microphone 9 shrink back in recess 2, prevent that microphone 9 from placing outdoor being infected with dust etc. in the top of lifting podium 1 during long-term when not using, and then influence the clean degree of microphone 9 when using, place through accomodating microphone 9, more be favorable to carrying out dustproof guard work to microphone 9, and then more be favorable to the use to the integrated device.

When the microphone 9 needs to be used, the first rotating shaft 3 is rotated to drive the gear 4 to rotate with the ratchet wheel 10, the ratchet wheel 10 rotates to enable the teeth to gradually push the ratchet handle 12 to drive the first torsion spring 13 to rotate and to intermittently rotate to be separated from the space between the teeth, the first torsion spring 13 resets under the elastic force effect of the first torsion spring and reenters between the teeth, and meanwhile, the gear 4 rotates to drive the toothed plate 5 to upwards move and drive the microphone 9 to upwards move and gradually protrude out of the top of the groove 2.

Through rotating first pivot 3 and then make microphone 9 remove from the recess 2 gradually, simultaneously because the acanthosis 12 is to ratchet 10 pivoted auto-lock nature, consequently can make microphone 9 remove from the recess 2 in highly adjusting and fix a position at any time, make the outstanding recess 2 of microphone 9 highly can adjust, make microphone 9 be more convenient for carry out more nimble use to the people of different heights, and then more be favorable to the result of use to lift podium 1.

Recess 2's top fixedly connected with third pivot 15, the top fixedly connected with apron 16 of third pivot 15, apron 16 rotates at recess 2's top to be connected, and the area of apron 16 is greater than recess 2's open area, and second torsion spring 17 has been cup jointed in the surface activity of third pivot 15, and second torsion spring 17's left side fixed connection is at the top of lift podium 1, and second torsion spring 17's right side fixed connection is on the surface of third pivot 15.

Under quiescent condition, under second torsion spring 17's elastic force effect, apron 16 blocks recess 2's top, the inside of recess 2 is entered into from recess 2 to effectual dust etc. of preventing, when microphone 9 upward movement from recess 2, microphone 9 promotes apron 16 smoothly and rotates, apron 16 rotates and drives third pivot 15 and rotate and drive second torsion spring 17 and rotate and produce deformation, apron 16 no longer blocks recess 2's top this moment, when microphone 9 resets and contracts into recess 2 in, apron 16 no longer receives the promotion of microphone 9 and blocks this moment, under second torsion spring 17's elastic force effect, apron 16 rotates and resets to block recess 2's top again.

Stop recess 2's top through apron 16, and then when making microphone 9 be located recess 2, prevent that the dust from entering into recess 2's inside in the recess 2, improved the dustproof protective effect to microphone 9, the protective capacities of accomodating of being more convenient for to microphone 9 makes the use of integrated device perfect more.

The working principle is as follows: when the microphone 9 is not used, the microphone 9 needs to be stored into the groove 2, in a static state, under the elastic force action of the first torsion spring 13, the ratchet 12 is located in teeth of the ratchet 10 and blocks the ratchet 10 in the left rotation direction, the sliding block 6 is located at the topmost part of the sliding groove 7 at the moment, the spring 8 is in a stretching state, the elastic force of the first torsion spring 13 is larger than that of the spring 8, when the microphone 9 needs to be stored, the second rotating shaft 11 is rotated, the second rotating shaft 11 rotates to drive the first torsion spring 13 to rotate and deform, meanwhile, the second rotating shaft 11 rotates to drive the ratchet 12 to rotate and disengage from teeth of the ratchet 10, at the moment, under the elastic force action of the spring 8, the sliding block 6 moves downwards to drive the toothed plate 5 and the microphone 9 to move downwards, the microphone 9 moves downwards to contract into the groove 2, the toothed plate 5 moves downwards to drive the gear 4 to rotate, the gear 4 rotates to drive the first rotating shaft 3 to rotate to drive the ratchet 10 to rotate, after the microphone 9 is fully contracted into the groove 2, the movement of the ratchet 11 is stopped, the ratchet 13 returns to the second torsion spring 12, and the spring 13 returns to the elastic force action.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
