Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 and fig. 2, the present invention provides a technical solution: the utility model provides a rubber seal device with protect function, including top cap 1, the inside roof of top cap 1 is equipped with mounting groove 2, fixed mounting has thermal-insulated cotton layer 3 in mounting groove 2, thermal-insulated cotton layer 3 has good thermal-insulated cold-insulated effect, avoid low temperature invasion and attack rubber layer 4, the bottom fixed mounting on thermal-insulated cotton layer 3 has rubber layer 4, the bottom integrated into one piece on rubber layer 4 has convex layer 5, lateral wall and the inside wall laminating of notes oil pipe through convex layer 5, and then increase sealed effect once more, the lateral wall integrated into one piece of convex layer 5 has snap ring 6, the setting of snap ring 6, self elasticity through rubber increases the leakproofness with notes oil pipe inside wall, both ends all are equipped with mounting 7 about top cap 1, top cap 1 is connected with internal thread ring 8 through mounting 7.

Particularly, the bottom edge on rubber layer 4 is equipped with arcwall face 9, and arcwall face 9 is the integrated into one piece structure of the bottom edge on rubber layer 4, and the bulge degree of the bottom edge on the arcwall face 9 multiplicable rubber layer 4, back in the internal thread ring 8 when oiling pipe spiro union, the top of oiling pipe can degree the bottom edge on rubber layer 4 and cause serious wearing and tearing, can reduce this degree of wear through arcwall face 9.

Specifically, the heat insulation cotton ring 10 is provided inside the internal thread ring 8, and the heat insulation cotton ring 10 can increase the cold insulation and heat insulation effects of the whole body shown in fig. 1.

Specifically, the fixing member 7 includes an upper fixing ring 11, a lower fixing ring 12 and a bolt 13, the upper fixing ring 11 and the lower fixing ring 12 are respectively fixedly mounted on the outer side walls of the top cover 1 and the internal thread ring 8, and the top end of the bolt 13 penetrates through the lower fixing ring 12 and the upper fixing ring 11 and is screwed with a nut 14.
