Description
Technical Field
The utility model relates to a decibel meter field especially relates to a novel decibel meter is connected device.
Background
The vehicle is easy to jolt because of uneven ground in the driving process, so that ground vibration is caused, the outdoor decibel measuring instrument is influenced by vibration and is easy to rotate relative to the fixed rod, and parts of the decibel measuring instrument are loosened.
SUMMERY OF THE UTILITY MODEL
The utility model discloses it is not enough to the above-mentioned that prior art exists, provide a location accurate novel decibel meter connecting device.
The utility model aims at realizing through the following technical scheme:
the utility model provides a novel decibel measurement appearance is connected device, includes dead lever, installation cover, decibel measurement appearance, spacing flange, dead lever upper portion has the erection column, the erection column lower part has positioning flange, the installation cover has the mounting panel, decibel measurement appearance is connected in the mounting panel outside, the inside erection column hole that has of installation cover, the erection column hole suits with the erection column, erection column connection erection column hole, the erection column card is downthehole at the erection column, installation cover sub-unit connection positioning flange, erection column upper portion has the fastening arch, the fastening arch passes through threaded connection spacing flange, a plurality of spacing nails are connected in the spacing flange outside, spacing nail passes spacing flange connection installation cover.
The mounting post outside has a plurality of location archs, the mounting post hole has a plurality of location protruding grooves, location protruding groove suits with the location arch, location protruding connection location protruding groove, the location protruding card is in location protruding inslot.
The positioning protrusions are arranged on two sides of the positioning protrusion, the positioning protrusion grooves are arranged on two sides of the positioning protrusion groove, the limiting protrusion grooves are connected with the limiting protrusions, and the limiting protrusions are clamped in the limiting protrusion grooves.
Has the advantages that:
the mounting post card is in the mounting post downthehole, makes the part location between decibel meter and dead lever accurate, confirms decibel meter and dead lever relative position, and positioning flange, spacing flange cooperation can restrict decibel meter mounting height, make decibel meter be difficult for receiving the vibrations influence to take place the drunkenness in vertical side, stable in structure. The protruding card in location takes place to rotate on making the installation cover can not the dead lever again in the protruding inslot in location, offsets the axial force that the installation cover received, makes the decibel measurement appearance take place the circumference rotation on can not the dead lever again, confirms the decibel measurement appearance orientation, improves the measuring degree of accuracy. Spacing protruding card is in spacing protruding inslot, and when the installation cover had the rotation trend, the big more spacing arch of axial force was connected inseparabler with spacing protruding groove, prevents spacing arch and takes place the displacement, and then makes installation cover and dead lever keep relative position definite state, rational in infrastructure. The stop pin connects gradually spacing flange, mounting sleeve, makes spacing flange and mounting sleeve relative stable in structure, and then makes spacing flange fastening arch relatively take place to rotate for spacing flange fastening arch relatively can not back out, thereby makes the relative erection column's of spacing flange position-finding, and the erection column can restrict the mounting sleeve upwards take place the displacement, and then confirms decibel measurement appearance mounting height.

Detailed Description
The invention is explained in more detail below with reference to the figures and examples:
the utility model provides a novel decibel measurement appearance connecting device, includes dead lever 1, mounting sleeve 4, decibel measurement appearance 6, flange 12, 1 upper portion of dead lever has erection column 2, 2 lower parts of erection column have flange 3, mounting sleeve 4 has mounting panel 5, decibel measurement appearance 6 is connected in the 5 outside of mounting panel, 4 inside erection column holes 14 that have of mounting sleeve, erection column holes 14 suit with erection column 2, erection column holes 14 are connected to erection column 2, 2 cards of erection column are in erection column holes 14, 4 sub-unit connection flange 3 of mounting sleeve, 2 upper portions of erection column have fastening arch 11, fastening arch 11 passes through threaded connection flange 12, a plurality of stop nails 13 are connected in the flange 12 outside, stop nail 13 passes flange 12 and connects mounting sleeve 4.
The mounting post 2 outside has a plurality of location archs 7, the mounting post hole 14 has a plurality of location protruding grooves 8, location protruding grooves 8 suits with location arch 7, location protruding grooves 8 are connected to location arch 7, location arch 7 card is in location protruding grooves 8.
The two sides of the positioning protrusion 7 are provided with limiting protrusions 9, the two sides of the positioning protrusion groove 8 are provided with limiting protrusion grooves 10, the limiting protrusion grooves 10 are connected with the limiting protrusions 9, and the limiting protrusions 9 are clamped in the limiting protrusion grooves 10.
The mounting column 2 card is in mounting column hole 14, and the part location that makes decibel meter 6 and dead lever 1 within a definite time is accurate, confirms decibel meter 6 and dead lever 1 relative position, and flange 3, limiting flange 12 cooperate, can restrict decibel meter 6 mounting height, make decibel meter 6 be difficult for receiving the drunkenness that vibrations influence takes place vertical side drunkenness, stable in structure. The protruding 7 cards in location take place to rotate on making installation cover 4 can not dead lever 1 again in the protruding groove 8 in the location, offsets the axial force that installation cover 4 received, makes decibel meter 6 can not take place the circumference again and rotate on the dead lever 1, confirms decibel meter 6 orientation, improves the measuring degree of accuracy. Spacing arch 9 card is in spacing protruding groove 10, and when installing sleeve 4 had the rotation trend, the big more spacing arch 9 of axial force is connected inseparabler with spacing protruding groove 10, prevents spacing arch 9 and takes place the displacement, and then makes installing sleeve 4 and dead lever 1 keep relative position definite state, rational in infrastructure. Stop pin 13 connects gradually flange 12, installation cover 4, makes flange 12 and installation cover 4 relative stable in structure, and then makes flange 12 can not fastening protruding 11 relatively take place to rotate, makes flange 12 can not fastening protruding 11 relatively back-out, thereby makes the position of flange 12 relative erection column 2 confirm, and erection column 2 can restrict installation cover 4 upwards take place the displacement, and then confirms 6 mounting heights of decibel meter.
