Description

Technical Field

[0001] The utility model belongs to the technical field of sealing pads, and in particular relates to an insulating rubber sealing pad. Background Art

[0002] Rubber sealing gaskets are a type of gasket used for sealing. The main products of rubber sealing gaskets include: silicone gaskets, nitrile rubber gaskets, fluororubber gaskets and other rubber gaskets. Rubber sealing gaskets are resistant to oil, acid and alkali, cold and heat, and aging, and are widely used in the automotive, electronics, chemical, antistatic, flame retardant and food industries.

[0003] At present, the contact surface between the existing rubber gasket and the workpiece is mostly a plane, so that only one sealing surface can be formed between the gasket and the workpiece. When the surface of the gasket is broken, its sealing effect will fail, thereby greatly reducing the use effect. Utility Model Content

[0004] The utility model aims to provide an insulating rubber sealing pad to solve the technical problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the specific technical scheme of the utility model is as follows: an insulating rubber sealing gasket, comprising a first sealing gasket and a second sealing gasket located below the first sealing gasket, the first sealing gasket and the second sealing gasket are each provided with three convex strips on the side away from each other, a steel ring is provided at the bottom of the first sealing gasket, a limiting ring distributed corresponding to the steel ring is provided on the upper surface of the second sealing gasket, an annular groove is provided on the upper surface of the limiting ring, the bottom of the steel ring extends to the inside of the annular groove and is slidably connected thereto, and a plurality of springs are provided between the bottom of the steel ring and the bottom inner wall of the annular groove.

[0006] Preferably, the three convex strips are annular structures, and the diameters of the three convex strips decrease sequentially.

[0007] Preferably, the side of the convex strip away from the first sealing gasket and the second sealing gasket is configured as a pointed structure.

[0008] Preferably, eight springs are provided, and the eight springs are distributed in a circular array.

[0009] Preferably, the inner wall of the steel ring contacts the inner ring side wall of the annular groove, an annular convex edge is provided at the bottom edge of the steel ring, the annular convex edge contacts the outer ring side wall of the annular groove, and the annular convex edge is slidingly connected to the annular groove, and an annular rib is provided at the top outer ring edge of the annular groove.

[0010] Preferably, four limiting openings distributed in a circular array are arranged at the edge of the annular convex edge, and limiting blocks distributed one-to-one with the limiting openings are arranged on the inner wall of the annular groove, and the limiting blocks are slidably connected with the limiting openings.

[0011] Preferably, the surfaces of the steel ring, the limiting ring and the spring are all coated with epoxy resin.

[0012] The utility model provides an insulating rubber sealing pad with the following advantages:

[0013] 1. The utility model provides three convex strips of different diameters so that when the insulating rubber sealing gasket contacts the workpiece, three sealing contact surfaces can be formed, thereby greatly improving the sealing effect. Even if one of the convex strips is broken, it will not affect the sealing performance. By providing a steel ring and an annular groove for sliding connection and cooperating with a spring, the first sealing gasket and the second sealing gasket can be contracted, thereby making it simpler and more convenient to install the rubber sealing gasket. Under the action of the spring elastic force, the first sealing gasket and the second sealing gasket can be tightly connected to the contact surface of the workpiece, thereby greatly improving the sealing effect.

[0014] 2. Through the cooperation between the limit block and the limit opening, the steel ring and the annular groove can only move up and down, and the steel ring cannot roll in the annular groove, which greatly improves the stability of the structure. BRIEF DESCRIPTION OF THE DRAWINGS
