Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in figures 1-4, protecting against shock frequency converter includes 1, two, shell functional module 2, two stabilizer 3, damping
Beam 4 and mounting rail 5；Two stabilizers 3 are fixed in shell 1 by separating crossbeam 9 in upper and lower；Functional module 2 passes through stabilization
Device 3 is fixed in shell 1；Stabilizer 3 includes cuboid framework 31, elastic card convex 32；Card convex 32 is above and below framework 31
On the bar of framework 31 of left and right four；And up and down and left and right distinguish two-by-two one group it is relative；Up and down on four surfaces of functional module 2
It is equipped with the groove 21 for arc with 32 corresponding bottom of card convex；The cross section of buffer beam 4 and mounting rail 5 is flute profile；Damping
What beam 4 was parallel to each other is arranged on the bottom of shell 1；A wing side and the bottom of shell 1 for buffer beam 4 is affixed, and two buffer beams 4 are opened
Mouth is opposite；One wing side of one mounting rail 5 is in the groove of a buffer beam 4；One wing side of buffer beam 4 and base it is interior
Surface is equipped with and a wing side of mounting rail 5 and the compression spring 8 of end contact；The end face in the same direction of two mounting rails 5 is equal
Fixed plate 51 provided with closure groove face, other end are provided with the portable plate 52 of closure groove face；
By setting elastic card convex 32 in functional module 2, setting groove 21 to realize in framework 31 can be by function mould
Block 2 is fixed in framework 31；By setting the buffer beam 4 and mounting rail that are linked together by compression spring 8 in the bottom of shell 1
