When installation, need before sounding monomer 20 is installed to mounting groove 114, first to 1151 He of supporting surface of bracket 115
It positions and carries out gluing at side wall 1152, at this point, groove 1153 can also be filled glue.Then again by sounding monomer 20 be installed on by
For bracket 115 in the mounting groove 114 made of, 20 bottom surface 21 of sounding monomer is bonded in the branch of bracket 115 because of the effect of glue
On support face 1151.The side 22 of sounding monomer 20 is viscous by the glue in the glue and groove 1153 on positioning side wall 1152 simultaneously
Knot extremely positioning side wall 1152.It is described after the glue solidifies in the supporting surface 1151, positioning side wall 1152 and groove 1153
The supporting surface 1151 of bracket 115, positioning side wall 1152, the bottom surface 21 of groove 1153 and sounding monomer 20, can shape between side 22
At a cementing layer 1154, keep gluing between sounding monomer 20 and lower casing 11 fixed, the waterproof of sounding monomer 20 is made to realize
With.
It is arranged on upper casing 12 it is appreciated that container 113, mounting groove 114 and bracket 115 also can according to need.
In the present invention, due to being provided with groove on the cemented surface of shell holder and sounding monomer, make sounding monomer with
Cementing layer loading between shell holder increases and bonding surface product increases, which is attachment with the cell wall of the groove
Point enhances the cementing layer overall adhesion, and then strengthens the integral strength of the cementing layer, to prevent cementing layer from occurring
Disconnected glue phenomenon, greatly improve waterproof performance.
It should be noted that the directional instruction (such as upper and lower, inside and outside, top, bottom ...) of institute is only in the present invention
For explaining in the relative positional relationship etc. under a certain particular pose (as shown in the picture) between each component, if the particular pose
When changing, then directionality instruction also correspondingly changes correspondingly.
Above-described is only embodiments of the present invention, it should be noted here that for those of ordinary skill in the art
For, without departing from the concept of the premise of the invention, improvement can also be made, but these belong to protection model of the invention
It encloses.
