It is deformed when rubber seal is squeezed power by lateral pressure and is bonded with insulating body, so that pressure is more uniform, to protect
Demonstrate,prove the air-tightness between insulating body and seal case, it is ensured that reliable sealing herein, and also increase rubber seal
Service life.
Detailed description of the invention
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the A-A cross-sectional view in Fig. 1.
Specific embodiment
The technical issues of in order to solve the utility model, the technical solution of use, the technical effect of acquirement it can be readily appreciated that
Below with reference to specific attached drawing, specific embodiments of the utility model will be further explained.
It should be noted that illustrating only part related with the utility model for ease of description, in attached drawing rather than complete
Portion's structure.
As shown in Figs. 1-2, in a specific embodiment of the utility model, a kind of gas-filling cabinet insulating sleeve is provided
Sealing structure comprising the outer surface of insulating body 1 and conductive rod 2, the middle part of conductive rod 2 is equipped with multiple ring-shaped grooves 9, should
Multiple ring-shaped grooves 9 are uniformly distributed along the axial direction of conductive rod 2.
The insertion end 101 that insulating body 1 is connect with seal case is located at the right end of the insulating body 1, is inserted on conductive rod 2
One end of seal case is additionally provided with the limiting section 6 of a tetragonal structure.Insulating body 1 uses plastic material, preferably asphalt mixtures modified by epoxy resin
Rouge；Conductive rod 2 is cylindrical conductive metal, preferably copper.
Insulating body 1 and conductive rod 2 are integrated by high temperature casting.
Since the ring-shaped groove 9 on conductive rod 2 has multiple, the seam of gas joint between conductive rod 2 and insulating body 1
