Outside portion on be provided with support portion, before supporting block is cooperated by the front end of screw thread and inserted link, and supporting block stretches out movable sleeve
Side；The interior bar is inserted into outer bar from the rear end of outer bar, and outer bar is cooperated by adjusting screw and interior bar, the rear end setting of interior bar
There is scale, the rear end of outer bar is arranged in fixed block, and fine tuning set is located at the rear side of outer bar, and is fixed in interior bar, fine tuning set
Cooperated by fine-tuning nut and fine tuning screw rod and fixed block.
Preferably, the keyway for placing key pin is provided in the outer bar, the rear end of movable sleeve, which is provided with, to extend internally
Key pin sliding groove, key pin and key pin sliding groove cooperate.
Preferably, the outer bar long 1100 ± 0.1mm, the long 1070mm of interior bar.
Preferably, the interior bar and outer bar clearance fit, gap are 0.05 ~ 0.10mm.
Preferably, the scale of the interior bar is the groove since rear end face, and ruling span 1mm, every 10mm carve corresponding number
Word.
Preferably, the support portion is rod-shaped or cyclic structure, and the front end of supporting block is chondritic.
Due to the application of the above technical scheme, the utility model has the advantage that compared with prior art
The large-size inner diameter measurement ruler of the utility model passes through outer bar, interior bar, movable sleeve and supporting block phase interworking
It closes, easily tool can be made to match with workpiece diameter, directly display internal diameter using extension bar principle, as a result can be accurate to
1mm, overall structure is simple, practical and convenient, can measure the internal diameter of different workpieces, and the scope of application is wider.
Detailed description of the invention
Technical solutions of the utility model are described further with reference to the accompanying drawing:
Attached drawing 1 is the use schematic diagram of the large-size inner diameter measurement ruler of the utility model；
Attached drawing 2 is the decomposition diagram of large-size inner diameter measurement ruler described in the utility model.
Specific embodiment
With reference to the accompanying drawing and specific embodiment the utility model is described in further detail.
As shown in Figs. 1-2, a kind of large-size inner diameter measurement ruler described in the utility model includes outer bar 1, interior bar 2, activity
Set 3, supporting block 4, spring 5, key pin 6, fine tuning set 7 and fixed block 8；The front end of the outer bar 1 is provided with inserted link 11, and spring 5 is set
It sets on inserted link 11, inserted link 11 and spring 5 are inserted into movable sleeve 3 together, and support portion 12 is provided on the outside portion of movable sleeve 3, prop up
Support part 12 is rod-shaped or cyclic structure；The keyway for placing key pin 6, the rear end setting of movable sleeve 3 are provided in the outer bar 1
There is the key pin sliding groove to extend internally, key pin 6 and key pin sliding groove cooperate, and allow movable sleeve 3 along the direction of key pin sliding groove
Sliding, to be adapted to the workpiece 14 of different inner diameters；The supporting block 4 is cooperated by the front end of screw thread and inserted link 11, and supporting block 4 is stretched
The front end of the front side portion of movable sleeve 3 out, supporting block 4 is chondritic, to be adapted to the arc inner wall of workpiece 14；The interior bar 2 from
Outer bar 1 is inserted into the rear end of outer bar 1, and outer bar 1 is cooperated by adjusting screw 13 and interior bar 2, the long 1100 ± 0.1mm of outer bar 1, interior bar 2
With 1 clearance fit of outer bar, gap is 0.05 ~ 0.10mm, and interior bar 2 is 1070mm long；The rear end of the interior bar 2 is provided with scale,
