Abstract

The invention discloses a tightening liquid injection type pipe opening plug which comprises a pipe plug body. The pipe plug body comprises a cover, an outer wrapping face and an inner wrapping face, wherein the outer wrapping face and the inner wrapping face wrap a pipe wall. A lifting handle is arranged on the cover, one end of the lifting handle is vertically hinged to the edge of the cover, a rotary tightening device is arranged on the lifting handle, and a glue injecting pipe penetrates through the cover. The outer wrapping face is provided with a steel wire channel which surrounds a pipe body and is used for allowing a steel wire to penetrate. Compared with the prior art, according to the tightening liquid injection type pipe opening plug, the steel wire is used for fastening the pipe wall, the steel wire is then rotated, tightened and lifted through the lifting handle, and thus the sealing effect to a pipe opening by the whole pipe plug body can be better.

Description

technical field [0001] The invention relates to a sealing device, in particular to a tightening type nozzle plug. Background technique [0002] With the rapid development of the current automobile industry, there are more and more varieties of various pipe parts. During their production and processing, hydraulic tests or air tightness tests are often required, such as air intake pipes, air outlet pipes, and water inlet pipes. , drainage pipes, etc., and the nozzles need to be sealed when performing these tests. In the past, the sealing devices were fixed, that is, the specific position of each nozzle on the product in the entire fixture was calculated in advance, and then the sealing mechanism was designed at the corresponding position. However, due to the diversity of pipe parts at present, some products have complex shapes, and there are space angles between the nozzles, which makes the fixture design difficult. [0003] There are certain difficulties in both production ...
