Wall bushing embedding device with extension function

Abstract

The present invention overcomes the deficiencies of the prior art, and provides a pre-embedded device for the wall-piercing casing with a telescopic function, which prevents the phenomenon of cracking caused by the reserved holes in the wall, and at the same time plays the role of sealing the connecting pipe and making the wall beautiful; In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: a pre-embedded device for wall-piercing casing with telescopic function, including an outer casing, an inner casing and a sealing module, the outer casing and the inner casing are both cylindrical structure, the outer sleeve is movably fitted on the inner sleeve, and a positioning boss is provided on the outside of one end of the inner sleeve, the outer sleeve and the inner sleeve cooperate to form a telescopic sleeve, and the sleeve The parts are pre-buried in the wall, and the two ends of the set are provided with sealing modules, and the sealing modules are used for positioning the plug-in external pipes and wires, and can seal the plug-in parts; the present invention can be widely used in The field of wall bushings.

Description

technical field [0001] The invention discloses a pre-embedded device for wall-piercing bushings with telescopic function, belonging to the technical field of wall-piercing bushings. Background technique [0002] Water supply, drainage pipes, power supply, gas pipelines, network cables, firefighting pipelines, etc. in the modern construction industry need to go through the wall to enter the house, and the wall has large and small holes. The traditional method is to drill holes, robot workers drill holes, set Through the wall casing, etc., this will cause the problem of plugging the hole, the cement mortar will form dry cracks, and the plugging will cause problems. Some wall casings are not blocked at all, threatening that this is thermal expansion Shrinking expansion joints. In this way, insects, ants and dust will naturally enter the home, bringing environmental, hygiene and health problems to the residents. Contents of the invention [0003] The invention overcomes the ...
