Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The utility model provides two technical schemes:

fig. 1, 3-4 show a first embodiment: the utility model provides a pipeline leaking stoppage piece, including locking structure 1, locking structure 1's inside can run through and have taut rubber coating rope 2, and locking structure 1 includes lock sleeve 11, and embedded fixedly connected with rubber pad 12 in the top of lock sleeve 11, perforation 13 that link up from top to bottom have all been seted up to the inside both sides of rubber pad 12 and lock sleeve 11, can overlap in the middle of taut rubber coating rope 2 and locate treating shutoff pipeline outside and both ends and pass both sides perforation 13 respectively, and the equal threaded connection in the left and right sides of lock sleeve 11 has fastening bolt 14 that can compress tightly taut rubber coating rope 2.
