Description

Dustproof rubber sealing ring Technical Field The utility model relates to the technical field of sealing rings, in particular to a dustproof rubber sealing ring. Background A seal ring is an annular sealing element, typically made of an elastic material, for preventing fluid leakage. The sealing ring has the core effects that a physical barrier is formed by filling a gap between two contact surfaces, medium leakage from a high pressure side to a low pressure side is prevented, external pollutants are prevented from entering the system, the sealing ring can seal connecting parts of articles or machines, medium leakage is prevented, sealing rings of different materials and shapes can be used in different places, the sealing ring is very wide in application, and the sealing ring can be used in different fields of hardware plastics, water supply and drainage, heating, ventilation and air conditioning, fire protection, automobiles and the like. At present, when the rubber sealing ring is used, the rubber sealing ring is extruded and laminated and sealed only by means of the elastic force of the rubber sealing ring, and the rubber sealing ring can generate a thermal expansion and contraction effect, so that the rubber sealing ring is deformed, the sealing effect of the rubber sealing ring is reduced, the dustproof effect of the sealing ring is affected, and therefore the dustproof rubber sealing ring is required to be designed to solve the problem. Disclosure of utility model The utility model aims to provide a dustproof rubber sealing ring to solve the defects in the prior art. In order to achieve the above object, the present utility model provides the following technical solutions: A dust-proof rubber seal ring, comprising: the top surface of the sealing ring is provided with a mounting groove, and the inside of the mounting groove is fixedly connected with a placement ring; the fixing ring is arranged in the mounting groove, the fixing ring is connected with the placing ring through threads, and the top surface of the fixing ring is fixedly connected with a rotating ring; The support ring is fixedly connected to the outer wall surface of the rotating ring, the inner wall surface of the rotating ring is fixedly connected with the mounting ring, and the outer wall surface of the support ring and the inner wall surface of the mounting ring are fixedly connected with the sealing ring; And the positioning component is arranged on the top surface of the sealing ring and used for positioning the mounting ring. Preferably, the positioning member includes: The two positioning grooves are formed in the top surface of the sealing ring, the positioning rings are fixedly connected to the bottom surface of the mounting ring and the bottom surface of the supporting ring, and the positioning rings are movably sleeved with the positioning grooves. Preferably, the inside fixedly connected with extrusion ring of mounting groove, the standing groove has been seted up to the top surface of extrusion ring. Preferably, an elastic ring piece is arranged in the placing groove, and the top end of the elastic ring piece is fixedly connected with the bottom surface of the fixing ring. Preferably, the limiting grooves are formed in the left side and the right side of the inside of the placing groove, and the limiting rings are fixedly connected to the inner wall surface and the outer wall surface of the elastic ring piece. Preferably, the top surface of the mounting ring and the top surface of the supporting ring are provided with a plurality of anti-slip grooves, and the limiting ring and the limiting grooves are movably sleeved together. In the technical scheme, the dustproof rubber sealing ring provided by the utility model has the beneficial effects that: Through setting up the sealing ring, after the staff fixes the sealing ring in the position that needs to seal, can closely laminate together with the object through two sealing rings this moment, make the sealing ring when appearing producing deformation, through the secondary seal of two sealing rings, with this sealed effect that improves the sealing ring, simultaneously, reduce the dust and get into the sealed object of sealing ring inside, owing to solid fixed ring is in the same place with placing ring threaded connection, thereby be convenient for later stage dismantles and installs the sealing ring, change the sealing ring, through setting up the elastic ring piece, after the staff fixes the elastic ring piece in the inside of standing groove, the elasticity that the elastic ring piece released can extrude the extrusion ring, receive extruded extrusion ring can extrude the sealing ring this moment, make the sealing ring can closely laminate together with the object, further avoid the dust to get into sealing equipment's inside.
