The technical solution of the present invention is as follows：

A kind of pipeline endoscope probes into pipe auxiliary mould, including protects away from bar and be fixed on multiple cross clamps of the guarantor on bar Frame, cross four ends of described cross clamping frame are respectively equipped with fixed pulley, and the center of the cross clamping frame has and probes into pipe clamp hole, The circumference of the cross clamping frame is provided with clamp pin hole, and the described diameter for probeing into pipe clamp hole is adapted with the external diameter for probeing into pipe, described The diameter in clamp pin hole be adapted with external diameter away from bar is protected.

Cross clamping frame-adopt plastic material (material cost and weight are low), using elastic holder type form, in order to spy Enter the quick assembling of pipe；The symmetrically arranged cross end (having pulley hole) of surrounding makees spring to install pulley, two ends therein Use during folder folding.

The part of fixed pulley-cross clamping frame, is installed on four ends of cross clamping frame, plays reduction and tube wall frictional force Effect.

The structure of pipe clamp hole-cross clamping frame is probeed into, folder hole diameter is slightly less than by pipe diameter is probeed into, to ensure to probe into Guan An Firm (folder hole inner ring can also arrange rubber liner) after dress；

The part of clamp pin hole-cross clamping frame, to the installing hole for ensureing to be also served as while elastic clip folding part e.

Guarantor can obtain away from bar (bourdon tube)-material from the oxy-acetylene belt scrapped, and appropriate length be intercepted into, with ten When word clamping frame is used cooperatively, can play a part of to strengthen probeing into pipe rigidity and structural stability.

Spacing during cross clamping frame open state-cross clamp opening, it is ensured that probe into pipe and pipe is probeed into by opening loading Folder hole.

Compared with prior art, the invention has the beneficial effects as follows：

1st, solve current endoscope and probe into pipe using upper deficiency, the Checking on effect that endoscope greatly improved is (i.e. big The inspection of pipeline after the prolongation of path tube internal check distance, double 90 ° of parallel bending elbows)；

2nd, suitable for it is at present all portable endoscope equipment, without the need for customizing buying again, due to peeping in single covering The price of mirror device is higher, and the purchase cost of equipment can be greatly reduced；

3rd, the core component due to endoscope uses and maintenance cost is higher, the use of this tool component to probe into pipe, rises The effect of pipe service life is probeed into protecting and extending, maintenance cost is minimized；

When the 4th, using this tool component, in addition to rapid and convenient is installed, operation when pipeline is checked also greatly is facilitated.
