Specific embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings：
As shown in Figure 1, a kind of insulation caliper, including：Vernier locking device 3 after insulating bar 1, vernier caliper 2 and survey.Insulation
Bar is telescopic insulating bar.
Vernier caliper includes main scale 2.1, the vernier slide 2.2 being slidably arranged on main scale and outside diameter measuring structure.Main scale
It is connected with one end of insulating bar, specifically, main scale is rotatedly connected by shaft 4 and one end of insulating bar.Shaft is slided with vernier
The glide direction of seat is perpendicular.Vernier slide, which is located at, to be determined between exterior measuring measuring jaw and shaft.
Outside diameter measuring structure includes the dynamic exterior measuring for determining exterior measuring measuring jaw 2.3 and be arranged on vernier slide being arranged on main scale
Measuring jaw 2.4.The length for determining exterior measuring measuring jaw is more than dynamic exterior measuring measuring jaw.Towards the side for determining exterior measuring measuring jaw of dynamic exterior measuring measuring jaw to determine base
Quasi- face 2.31.Include dynamic datum level 2.41 and guiding surface 2.42 towards the side for the dynamic exterior measuring measuring jaw for determining exterior measuring measuring jaw.Dynamic base
Quasi- face is between guiding surface and main scale.Dynamic datum level is parallel with determining datum level.
The one end for determining exterior measuring measuring jaw being connect with main scale is defined as：Determine the root of exterior measuring measuring jaw；Far from determining for main scale connection
One end of exterior measuring measuring jaw is defined as：Determine the end of exterior measuring measuring jaw.Guiding surface and spacing between datum level is determined by determining external pelivimetry
The root of pawl gradually increases toward the end direction for determining exterior measuring measuring jaw.
As shown in Figure 1 and Figure 2, vernier locking device includes the guide rail 3.1 being arranged on vernier slide, is slided along guide rail after survey
Dynamic sliding block 3.5, the triggering push rod 3.2 being arranged on sliding block are used for vernier sliding seat locking in main scale on setting vernier slide
On clamping screw 3.3, the drive gear 3.8 that is arranged on clamping screw and be arranged on triggering push rod and with drive gear phase
The rack 3.4 of engagement.The glide direction of sliding block and the glide direction of vernier slide are perpendicular.It is parallel with main scale to trigger push rod,
And triggering push rod is located at the same side of dynamic datum level with main scale.
Clamping screw, rack and drive gear are located at the same side of triggering push rod.Drive gear is coaxial with clamping screw.Lock
Rubber block is additionally provided on the surface of the end of tight bolt.Rack is parallel with guide rail.The axis of clamping screw and guide rail are perpendicular,
