The present embodiment can guarantee that pressurizing block 20 has by setting elastomer 40 and bear against tested device 30 always
To be avoided as much as pressurizing block 20 and tested device 30 relative displacement occurs for trend, to ensure the reliability tested.The bullet
Property body 40 include sponge or spring.
The device crush resistance energy device for testing further includes limited block 50, which is placed in holding channel 101,
And along the descent direction of pedestal 10, which is located at the top of elastomer 40, i.e., elastomer 40 be sandwiched in pressurizing block 20 with
Between limited block 50；
The pedestal 10 is equipped with and optionally allows or prevent the movable latch mechanism of 50 opposite base of limited block 10.
In the present embodiment, the limited block 50, elastomer 40, pressurizing block 20 and tested device 30 are along the decline side of pedestal 10
To being sequentially arranged.
The present embodiment passes through setting limited block 50 using the support as elastomer 40, while by adjusting the position of limited block 50
It sets to adapt to the pressurizing block 20 and elastomer 40 of different size (such as different sizes, different weight).
In the present embodiment, the elastic acting force of elastomer 40 and the weight size of pressurizing block 20 can be according to actual to be measured
The concrete condition of examination device 30 is chosen.
A kind of embodiment, the pedestal 10 have top 102, and the holding channel 101 is through the top 102 of pedestal and in pedestal
Top 102 form the top opening 103 that passes through for tested device 30, pressurizing block 20, elastomer 40 and limited block 50.
The holding channel other end extends in pedestal and forms closed end (being not drawn into the present embodiment), tested device and the holding channel
Closing end in contact.That is, holding channel does not run through the bottom of pedestal, bottom and imperforation.
Another embodiment, the pedestal 10 have top 102, and the holding channel 101 is through the top 102 of pedestal and in base
One top opening passed through for tested device 30, pressurizing block 20, elastomer 40 and limited block 50 is formed on the top 102 of seat
103.The holding channel 101 through pedestal bottom 105 and in the bottom of pedestal formed one for limited block 50, elastomer 40,
The bottom opening 106 that pressurizing block 20 and tested device 30 pass through.It is described to be tested when pedestal 10 is installed on percussion mechanism 70
Device 30 is contacted with percussion mechanism surface 701.
The latch mechanism includes jackscrew 60 (also referred to as holding screw) and the screw hole on pedestal 10 with the cooperation of jackscrew 60
