Abstract

The invention discloses a locking type sealing washer with high airtightness. The locking type sealing washer with high airtightness comprises a rubber ring. A sealing part is arranged on the front side of the rubber ring. A sealing part is arranged on the back side of the rubber ring. A skeleton is arranged inside the rubber ring. The skeleton comprises a first piece body, a second piece body, afirst pressing ring and a second pressing ring. A separation distance is reserved between the first piece body and the second piece body. A center hole is formed in the first piece body. A center holeis formed in the second piece body. The first pressing ring is arranged on the side, away from the second piece body, of the first piece body and abuts against the first piece body. The second pressing ring is arranged on the side, away from the first piece body, of the second piece body and abuts against the second piece body. A first annular protrusion is arranged on the face of the side, awayfrom the first piece body, of the first pressing ring. A second annular protrusion is arranged on the face of the side, away from the second piece body, of the second pressing ring. According to the locking type sealing washer with high airtightness, the strength of the part, in a sealing groove, of the deformation enlargement part of the skeleton is utilized to improve the sealing effect of the washer on a sealing surface.

Description

technical field [0001] The invention relates to the technical field of forklift accessories, in particular to a locking gasket with high sealing performance. Background technique [0002] Gaskets are an important component in the steering system of forklifts. It is mainly used between two workpieces to seal the butt joint surfaces of the two workpieces. Generally, there are sealing parts on both sides that cooperate with the sealing grooves on the workpieces. However, limited by the material of the sealing gasket itself, it is prone to fatigue, so that it cannot be firmly abutted against the sealing surface of the workpiece, which affects its sealing performance, and needs to be improved urgently. Contents of the invention [0003] Based on the technical problems existing in the above-mentioned background technology, the present invention proposes a locking gasket with high sealing performance. [0004] The present invention proposes a locking type high-tight sealing gas...
