Specific embodiment:
Further explanation is done to the utility model with reference to the accompanying drawing.
As shown in Figure 1, a kind of quick helium of the utility model examines fixture, including core rubber 1, core rubber 1 is matched by connection
Pipe 2 is connect with compressed air source unit, by filling helium inside 1 heat exchanger 3 of core rubber or returning 3 helium gas inside of heat exchanger
It receives.The bottom of the core rubber 1 is equipped with butt joint 4, and 4 outer diameter of butt joint imports and exports internal diameter with heat exchanger 3 and matches, docking
First 4 outer circle is equipped with O-ring seal 5, the first clamping plate 6 and the first pressing version 7 is equipped in the side of core rubber 1, in core rubber 1
The other side is equipped with the second clamping plate 8 and the second pressing version 9, and the first clamping plate 6 and 8 lower end of the second clamping plate extend to butt joint 4
Two sides, the first connecting pin 10 is horizontal through the first clamping plate 6 and core rubber 1, the first pressing version 7 and 10 one end of the first connecting pin
It is connected, the second clamping plate 8 is connected with 10 other end of the first connecting pin, and the second connecting pin 11 is horizontal through the second clamping plate 8 and note
