Import rubber o-rings production factory is an experimental device for sealing structure. It can adjust the compression amount of rubber O-rings and the size and shape of the bushing, and is easy to replace and facilitate the arrangement of sensors. The utility model includes a cylinder assembly and a base; The cylinder tube assembly is composed of a lower part of the cylinder tube and an upper part of the cylinder tube to form a hexagon, two connecting ears are integrally provided on one opposite side of the hexagon, the center of the cylinder tube assembly is set as a circular cavity, and the A bushing is arranged concentrically on the inner wall, and an Import rubber o-rings production factory is arranged between the cylinder barrel assembly and the bushing groove; the cylinder barrel assembly is fixed on the "Y"-shaped bracket of the base; the top sides of the upper part of the cylinder barrel Axial limit assemblies are respectively provided, and the shape of the axial limit assemblies is "7" type, which consists of connecting rods, support rods and rolling bearings; one end of the support rods is fixed on the top of the upper part of the cylinder through a locking thin nut , the other end is suspended, the connecting rod is vertically connected with the suspended end of the support rod, and the lower end of the connecting rod is connected with a rolling bearing.

The above is a brief introduction to the relevant knowledge of the experimental device of the sealing structure of the Import rubber o-rings production factory.
