Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
As shown in Figure 1, the probing shell structure of one of the present embodiment LPS Linear displacement transducer, including hollow knot
2 measuring staffs of structure and the connector 1 for being sheathed on 2 end of measuring staff, the outer surface at the end measuring staff 2I open up 6 measuring staffs of uniform intervals setting
Outer groove 2.1,1 one end inner surface of connector is equipped with the first inside groove 1.1, when connector 1 is placed on 2 end of measuring staff, the first inside groove 1.1 with
Measuring staff outer groove 2.1 is correspondingly arranged, and epoxy 3, the first inside groove 1.1 and measuring staff are perfused between the first inside groove 1.1 and measuring staff outer groove 2.1
The setting of outer groove 2.1 can increase the bonding strength after epoxy 3 is perfused；1 other end inner surface of connector opens up in 2 second
Slot 1.2, the second inside groove 1.2 are respectively equipped with the O-ring seal 4 of the fluorubber material of high-temperature-resistant high-pressure-resistant, and O-ring seal 4 is set
On the one hand setting can prevent when epoxy 3 be perfused epoxy 3 to leak along hollow type measuring staff 2, another aspect in use can be with
Increase whole tightness；The inner surface at the end measuring staff 2II opens up the measuring staff inside groove of the ball sealer 5 for fluorubber material to be arranged
2.2, epoxy 3 is perfused inside the end measuring staff 2II of measuring staff inside groove 2.2, on the one hand the setting of measuring staff inside groove 2.2 can increase close
On the other hand frictional force between blocking 5 and measuring staff 2 also can increase the bonding strength between epoxy 3 and measuring staff 2.
Above-mentioned measuring staff 2 is made of the strong carbon fibre materials of high temperature resistant, tensile capacity, and connector 1 is 304 stainless steel materials
Part is process by CNC, improves the outer dimension precision and rough surface grade of connector 1.
In addition to the implementation, the utility model further includes having other embodiments, all to use equivalents or equivalent
The technical solution that alternative is formed, should all fall within the protection scope of the utility model claims.
