Furthermore, the gaging hole is rectangle structure for fixing backing tube, the gaging hole.The survey of rectangle structure
Hole and the shape of backrest tube section match, and can preferably fix the direction of backing tube.
Furthermore, the material of the sealed liner is high fever compressed sponge.Make sealed liner that there is high temperature resistant, corrosion resistant
It is erosion, wear-resistant and the features such as be unlikely to deform, it can be used for a long time, and the reliability of guarantee test.
Furthermore, the sealed liner surveys mouth interference fit with experiment, forms labyrinth seal structure.Mouth is surveyed in experiment
Screw thread stretch into and form labyrinth seal structure in sealed liner, sealing effect is good.
A kind of connection method as described above for surveying the fixed attachment device of mouth with experiment for backing tube, feature exist
In the connection method is as follows：Backing tube is penetrated into the inside of telescopic scale and passes through gaging hole, according to actual needs using stretching
Contracting formula scale chooses backing tube and enters the length of gaging hole, will experiment survey mouth be inserted into sealed liner inside until its screw thread completely into
Enter in sealed liner, you can tested.Easy to operate, test accuracy is high.
Compared with prior art, the present invention haing the following advantages and effect：
1）Using labyrinth sealing principle, experiment not only may be implemented and survey the good sealing of mouth, and backing tube can be carried out
It is firmly fixed, improves the precision of experiment, accelerate the process of experiment.
2）Sealed liner uses high fever compressed sponge, has the characteristics that high temperature resistant, corrosion-resistant, wear-resistant and be unlikely to deform,
The service life for increasing attachment device improves the accuracy of experiment.
3）The depth that telescopic scale can neatly go deep into pipe backing tube is demarcated, and it is easy to efficiently solve circle ruler
The problem of modification and the wooden ruler heaviness, and telescopic structure can reduce the volume of equipment, it is easy to carry.
