Problems solved by technology

There are two major deficiencies in the existing O-shaped sealing ring: one is that when the hex nut or hex bolt is tightened, it is easily dislocated and deformed by the head of the hex nut or hex bolt, which seriously affects the sealing effect; When the hexagon nut or hexagon bolt is removed, the sealing ring is easy to fall off and lose from the screw rod

Embodiment 1

[0014] Embodiment 1: as figure 1 As shown, a sealing ring that is not easy to be dislocated and deformed is designed and manufactured, including a sealing ring body 1 and an elastic steel ring 2. The material of the sealing ring body 1 is rubber soft magnetic strip, and the elastic steel ring 2 is embedded in the sealing ring body 1. The section of the elastic steel ring 2 is a square structure whose thickness dimension is greater than the width dimension, and the axis of the elastic steel ring 2 is the same as that of the sealing ring body 1 .

[0015] The working condition of the present invention is: the magnetic side is towards the head of the hex nut or the hex bolt, the present invention is adsorbed together with the head of the hex nut or the hex bolt, and then tightened or unloaded by conventional methods.

Abstract

The invention discloses a displacement deformation-difficult O-shaped sealing ring. The O-shaped sealing ring comprises a sealing ring body and an elastic steel ring; the sealing ring body adopts the material of a rubber soft magnetic strip; the elastic steel ring is embedded in the sealing ring body; the section of the elastic steel ring is a square structure with a thickness size larger than a width size; and the axis of the elastic steel ring is the same with the axis of the sealing ring body. One magnetic surface is towards the head part of a hexagonal nut or a hexagonal bolt, so that the O-shaped sealing ring is absorbed with the head part of the hexagonal nut or the hexagonal bolt, and is tightened or unloaded by a conventional method. The O-shaped sealing ring not only can prevent displacement deformation to realize an excellent sealing effect, but also can prevent dropping from a screw rod and loss.

Description

technical field [0001] The invention relates to the technical field of sealing rings, in particular to an O-shaped sealing ring which is not easy to be misaligned and deformed. Background technique [0002] O-rings are most widely used in hydraulic and pneumatic transmission systems. There are two major deficiencies in the existing O-shaped sealing ring: one is that when the hex nut or hex bolt is tightened, it is easily dislocated and deformed by the head of the hex nut or hex bolt, which seriously affects the sealing effect; When the hexagon nut or hexagon bolt is removed, the sealing ring is easy to fall off and lose from the screw rod. Contents of the invention [0003] The problem to be solved by the present invention lies in the deficiencies in the prior art. It provides an O-shaped sealing ring, which can not only prevent dislocation and deformation, achieve a good sealing effect, but also avoid falling off and losing from the screw rod. [0004] The present inven...
