The limitation of range.
1 to Fig. 2 the fixation device of lamp tube electrode in the application air temperature fatigue test is done with reference to the accompanying drawing into one
Step is described in detail.
As shown in Figure 1, the fixation device provided by the present application for being lamp tube electrode in a kind of air temperature fatigue test is (referred to as
Fixed device), it may include cap nut 1 and elastic claw 2.
As shown in Fig. 2, elastic claw 2 may include the connecting pin 21 and clamping end 22 being fixedly connected；Connecting pin 21 have with
The matched external screw thread of 1 threaded hole of cap nut, 22 end of clamping end are in cone cylinder shape, and one end far from connecting pin 21 is major diameter
End, one end close to connecting pin 21 are miner diameter end, and the outer diameter of miner diameter end is less than 1 diameter of bore of cap nut, the outer diameter of bigger diameter end
Greater than 1 diameter of bore of cap nut, multiple grooves are offered to path extreme direction along bigger diameter end on the barrel of clamping end 22, it is recessed
Slot extends radially through barrel, and multiple grooves are uniformly distributed circumferentially.
Wherein, clamping end 22 has nature and clamp position:
When nature, clamping end 22 is located on the outside of 1 inner hole of cap nut, and the internal diameter of bigger diameter end is greater than lamp tube electrode bar
Diameter；
When clamp position, at least partly clamping end 22 follow connecting pin 21 screw in 1 inner hole of cap nut in, by inner hole into
Row squeezes, so that clamping end 22, which is shunk, clamps lamp tube electrode bar.
Further, in this embodiment the inner hole of preferably cap nut 1 includes thread segment and unthreaded hole section, unthreaded hole section is located at
Close to one end of elastic claw 2, to squeeze by unthreaded hole clamping end 22, so that extruding is more smooth, and clamping end is protected
