7. a kind of application method of the sound level meter with fixed device, it is characterised in that:
S1: first manually stirring two groups of guide plates (15) to two sides manually, and guide plate (15) can be along articulated stand at this time
(14) it rotates, while guide plate (15) will push guide rod (23) in the activity of outer cylinder (161) inner cavity, while push movable plate
(163) application pressure is carried out to spring lever (164), spring lever (164) is promoted to compress, while outer cylinder (161) can be around the
One hinged block (162) relatively rotates, and the guide pad (18) at left and right sides of sound level meter ontology (17) is then nested in guiding
In sliding slot (19) inner cavity, to can be realized the position-limiting action of guide pad (18) to sound level meter ontology by guide chute (19)
(17) limit prevents sound level meter ontology (17) from the displacement in up and down direction occurs, since what spring lever (164) compression generated returns
Elastic force can be transmitted on guide plate (15) by movable plate (163) support rod (165), so as to apply to sound level meter ontology (17)
The power for adding support to clamp；
S2: pulling pull block (25) manually, can promote guide rod (23) that clamping block (22) is driven to move outward, support simultaneously
Plate (26) can promote support spring (27) to compress, and subject-oriented piece (18) when sliding to the front end of guide chute (19), at this time
Grafting block (20) is nested in shackle passageway (13), and unclamping hand can use the screen resilience drive that support spring (27) compression generates
The clamping block (22) of guide rod (26) end is nested in two groups of limit plates (21), thus realize the limit to grafting block (20),
It can prevent grafting block (20) that the movement on front-rear direction occurs, the fixation to sound level meter ontology (17) can be realized；
S3: starting motor (7) by external power supply, and motor (7) will drive adjusting screw rod (9) rotation, due to lifter plate (4) and adjusts
Section screw rod (9) is spirally connected, so that the positive and negative rotation of motor (7) can promote adjusting screw rod (9) that lifter plate (4) is driven to move up and down,
During lifter plate (4) moves up and down, sliding block (5) sliding in sliding slot (6) can provide what lifter plate (4) moved up and down
Stability can guarantee the up and down motion linearity of lifter plate (4), by moving up and down for lifter plate (4), to realize to solid
Determine the adjusting of the height of device (11), the height of sound level meter ontology (17) can be adjusted, so as to be to promote sound level meter sheet
Body (17) realizes noise measuring.
