Embodiment
Accompanying drawing 1-2 is described in detail below to a kind of sound wave crystal fixation assembly of the utility model below.
Embodiment 1
A kind of sound wave crystal fixation assembly, for providing crystal 8 installation positioning and sealing, its structure includes being used for institute
State the outer protection component that crystal 8 plays the interior positioning component of interior fixation and outer protective effect is played to the crystal 8；In described
Fixation kit includes the interior locating shaft 6 through the endoporus of crystal 8, and is respectively sleeved at the both ends of the interior locating shaft 6 pair
Its middle part crystal 6 plays the first damping fixed block 5 and the second damping fixed block 9 of damping positioning；The outer protection component includes
The outer fixed shell 1 of the periphery of crystal 6 is set in, and closure is connected to the first of the both ends of outer fixed shell 1 respectively
