SEALING FIXING DEVICE FOR CABLES/PIPES PASSING THROUGH THROUGH HOLE IN ENCLOSING STRUCTURE Russian patent published in 2025 - IPC F16L5/08 H02G3/22 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to communication lines and is intended to provide sealing of pipes or cables entering a room through a wall, a floor or a ceiling. In the device, the sealing and fixing assembly comprises upper and lower annular metal plates with holes and a sealing component installed therebetween, wherein each of the upper and lower annular metal plates is made of at least two identical parts, and the sealing component consists of equal thickness elastic material annular plates clamped between the upper and lower annular metal plates parts by means of tightening bolts with nuts, and assembled inserts in the form of strips of elastic elastomer with a thickness of not more than 1 mm, fixed on the outer and inner cylindrical surfaces of the annular plates of the elastic material with the possibility of multiple gluing and ungluing with overlapping of the contact surfaces of the annular plates of the elastic material.

EFFECT: reliability of tightness, integrity of overlapping at sealing of carried products in the wide range of standard sizes with provision of their retention from axial and radial movements.
