Description

Rubber sealing ring for cab wire harness Technical Field The utility model relates to the technical field of sealing structures, in particular to a rubber sealing ring for a cab wire harness. Background The cab wire harness is an important component of the automobile, and the sealing performance of the cab wire harness directly influences the sound insulation, dust prevention, water prevention and other performances of the automobile. The performance of the rubber sealing ring of the wire harness of the cab directly influences the reliability of an electric system of the vehicle, and the design of the rubber sealing ring needs to integrate material characteristics, structural innovation and working condition requirements. Through accurate interference design, many lips seal structure and resistant material selection, can effectively promote sealed life-span and security, satisfy the increasingly strict waterproof, ageing-resistant requirement of automobile industry. The prior art discloses a patent with a publication number of CN216215704U, which comprises a rubber sealing ring body, a door plate and an auxiliary fixing mechanism, wherein an extrusion cavity is cut on the rubber sealing ring body, a plurality of evenly distributed holes are cut on the side wall of the extrusion cavity, the door plate is arranged on one side of the rubber sealing ring body, a wire harness hole is cut on the door plate, a wire harness pipe is connected between a pair of rubber sealing ring bodies, the auxiliary fixing mechanism is arranged in the extrusion cavity, the auxiliary fixing mechanism comprises a telescopic rod, one end of the telescopic rod is inserted into the extrusion cavity, and one end of the telescopic rod outside the extrusion cavity is connected with a fixing ball. Through the setting to the corresponding mechanism of pencil rubber seal, increase the fixed effect of rubber seal, make the rubber seal be difficult for droing when the installation with after the installation to be difficult for reducing the protection to the pencil, increase the life of pencil, reduce unnecessary loss for the user. The prior device gradually exposes the defects of the technology along with the use, and the prior device mainly comprises the following aspects: First, current sealing washer is when using for the sealing washer is when fixed the pencil of diameter difference because the diameter of pencil is different, and the pencil hole can't satisfy the fixed demand of different diameter pencil. Secondly, current sealing washer is limited by its fixed knot structure, can't realize quick and firm and the cab mounting hole is installed fixedly mutually, and then has reduced assembly efficiency. In summary, it is clear that the prior art has inconvenience and defects in practical use, so that improvement is needed. Disclosure of utility model Aiming at the defects in the prior art, the utility model solves the problem that when the sealing ring in the prior art is used, the sealing ring can not meet the fixing requirement of wire harnesses with different diameters when the wire harnesses with different diameters are fixed by the sealing ring due to different diameters of the wire harnesses. In order to solve the problems, the utility model provides the following technical scheme: The rubber sealing ring for the cab wire harness comprises a rubber sealing ring body, wherein a fixed wire harness hole and a variable wire harness hole are formed in the rubber sealing ring body, a plurality of sealing lips are arranged on the inner periphery of the variable wire harness hole, The periphery wall of the rubber sealing ring body is provided with a mounting groove in an encircling mode, and the rubber sealing ring body forms two sealing frameworks through areas on two sides of the mounting groove. As an optimized scheme, the rubber sealing ring body is rectangular.
