Embodiment
As shown in figure 1, a kind of portable bore inner diameter detection instrument, including umbrella skeleton 1, the axis of gathering can be strutted
Circular rod member 2, axis rod set I 3 and axis rod set II 4；The axis circle rod member 2 sequentially passes through axis rod set I 3 and central shaft rod
II 4 are covered, the axis rod set I 3 is actively socketed on axis circle rod member 2, and the axis rod set II 4 is also actively socketed on axis
On circular rod member 2.
As shown in Fig. 2 the axis circle rod member 2 is made of the tube and pipe of aluminium alloy thickening, upper and lower ends are shut, top
Add the handle 5 of a rubber, the effect of handle 5 is use of conveniently taking；The bottom of the axis circle rod member 2 is provided with rubber
Glue pier nose 6, after the rubber pier nose 6 effect is end-of-job, whole axis circle rod member 2 can be allowed to stand in ground or other coarse
It is pre- anti-wear on face.The scale 21 of black is etched with along its length in axis circle rod member 2（Precalculated scale is dredged
It is close）, the scale opens outer diameter of a circle by the umbrella skeleton 1 set in advance that converts and obtains；The beginning of the scale 21
A upper limit ring 7 is provided with, the tail end of scale 21 is provided with a lower limit ring 8；Upper and lower spacing ring in the present embodiment
External diameter is more bigger than the diameter of axis circle rod member 2, and axis rod set I 3 can be limited, axis rod set II 4 skids off meter full scale；
The axis rod set I 3 and axis rod set II 4 are between upper limit ring 7 and lower limit ring 8.Above and below axis rod set I 3
Slide, can be according to the scale 21 of black after the positioning of axis rod set I 3, measured circle S internal diameter corresponding to reading.
Umbrella frame of the umbrella skeleton 1 for strutting gathering as strutted umbrella, including some struts 11 and therewith
The reverse strut 12 being accordingly coupled；It radial can open and receive as strut 11 using eight thin rods of stainless steel in the present embodiment
Hold together；The inner of the strut 11 is integrated into axis rod set I 3, and be hinged with axis rod set I 3, and its outer end is provided with conical head
13；The position of described reversely one end of strut 12 and the about middle part of strut 11 is hinged, and its other end enters with axis rod set II 4
Row is be hinged；The axis rod set I 3 moves up and down along axis circle rod member 2 to be deployed strut 11 or collapses.
The conical head 13 of the outer end of strut 11 is connected with flexible elastic string 14, can so control conical head 13
Unordered it will not scatter.The elastic string 14 is extended out and elongated with conical head 13, is shortened with the interior receipts of conical head 13.It is described
Conical head 13 is made of rubber, because conical head 13 is used to contacting the inwall of measured circle, therefore be made of rubber can for conical head 13
Phase is contacted with inwall to prevent strut 11 mutually to wear.
The axis rod set I 3 is internally provided with steel bomb reed 31, as shown in figure 3, the steel bomb reed 31 is V-arrangement steel
Gap be present using between axis rod set I 3 and axis circle rod member 2 in spring leaf, the spring leaf 31（Axis rod set I 3 is justified with axis
The tolerance fit of shape rod member 2 between the two）Steel bomb reed 31 is set to be attached to the graduated surface of axis circle rod member 2, because
This axis rod set I 3 can carry damping when being slided up and down along axis circle rod member 2, can so fix central shaft rod at any time
I 3 are covered, ensures that measured circle internal diameter reading is accurate.
A kind of application method of portable bore inner diameter detection instrument of the present utility model：In use, hold handle on the other hand
Hand 5, the other hand hold axis rod set I 3 and open the strut 11 of umbrella skeleton 1 as umbrella, and at this moment axis rod set I 3 glides
Dynamic to drive the lower slider of axis rod set II 4, i.e. axis rod set II 4 is limited by lower limit ring 8 when axis rod set II 4 slides into lower limit ring 8
Live to push away motionless, continuation lower slider axis rod set I 3, you can so that the strut 11 of umbrella skeleton 1 is opened, as far as possible by each taper in position
First 13 can touch survey circle inwall（If some conical heads can not touch inwall, illustrate that the circle is sufficiently oily anon-normal
Circle）, referring to Fig. 5.Now, axis rod set I 3 is fixed, reads the one end of axis rod set I 3（Close to the end face of handle 5）It is corresponding
Scale, as measured circle internal diameter.After having used, this detection instrument is packed up as umbrella.
Among civil engineering, quality testing is an important job, and Quality People's labor intensity is big, this instrument
Using and it is easy to carry, reading is accurate, and manufacturing process is simple, and cost is cheap, can be combined with existing other quality testing kits
Together, there is certain market popularization value.
