Description of drawings
Fig. 1 is an one-piece construction synoptic diagram of the present invention.
Embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in Figure 1: the present invention mainly is made up of back-moving spring 1, top cover 2, knurled nut 3, push rod 4, resilient sleeve 5, pad 6, orienting sleeve 7, survey pin 8, end cap 9, mounting hole 10, sheet spring 11, slide opening 12, cone-shaped body 13, spacing preiection 14, through hole 15 etc.
Plug gauge head pore diameter measurement mechanism, it comprises that both sides, orienting sleeve 7 bottom offer mounting hole 10, sliding plug has the pin of survey 8 in mounting hole, at orienting sleeve 7 internal fixation resilient sleeve 5 is installed, offer slide opening 12 in the resilient sleeve 5, sliding plug has push rod 4 in slide opening 12, the bottom of push rod 4 is a cone-shaped body 13, orienting sleeve 7 is stretched out on the top of push rod 4, on the push rod 4 that is positioned at orienting sleeve 7 outsides, be provided with spacing preiection 14,14 of described spacing preiections are on orienting sleeve 7 end faces in slide opening 12 outsides, be fixed with top cover 2 in orienting sleeve 7 upper ends, the top ends of described top cover 2 is provided with through hole 15, stretch out in through hole 15 on the top of push rod 4, spacing preiection 14 is surrounded wherein by top cover 2, the push rod 4 outer back-moving springs 1 that are with of described spacing preiection 14 upper ends, the top ends of back-moving spring 1 is against top cover 2 inwalls in through hole 15 outsides, resilient sleeve 5 bottoms are provided with sheet spring 11 at interval corresponding to the both sides of surveying pin 8, the inner end of described survey pin 8 is against on the sheet spring 11 of a side separately, and cone-shaped body 13 is partially submerged in two gaps between the spring 11.
The outer end of described survey pin 8 is a spherical surface body.Described spacing preiection 14 is the circular projection that push rod 4 outer walls are provided with.Be bolted with knurled nut 3 on the orienting sleeve 7 of described top cover 2 lower ends.Be provided with pad 6 between resilient sleeve 5 and the orienting sleeve 7.Orienting sleeve 7 bottoms are provided with end cap 9.
