Description

Novel oil seal Technical Field The utility model relates to the technical field of framework oil seals, in particular to a novel oil seal. Background When the framework oil seal is used, the inner side of the oil seal is extruded and tightened mainly through shrinkage reset of the fastening spring, so that the inner wall surface of the oil seal is abutted against an object to seal, but the fastening spring is of an annular structure, the surface of the fastening spring is smooth, the environment of application is also easily contacted with substances such as lubricating oil and the like, the fastening spring is easy to fall off on the surface of the framework oil seal due to extrusion force of the fastening spring, the sealing effect of the framework oil seal is reduced, and meanwhile, the framework oil seal or the fastening spring part can be damaged when entering equipment. Disclosure of utility model Based on the technical problem that the surface of the existing framework oil seal lacks anti-falling function for a fastening spring, the utility model provides a novel oil seal. The novel oil seal comprises an oil seal main body, wherein an installation groove is formed in the inner side wall of the oil seal main body, a fastening spring is clamped on the inner wall of the installation groove, an anti-falling mechanism is installed on the inner side wall of the oil seal main body and comprises a gravity pipe, a supporting air bag is fixedly connected to the lower end surface of the gravity pipe, the inside of the supporting air bag is communicated with the inside of the gravity pipe, and the supporting air bag is located on the inner side of the fastening spring. Preferably, the inside wall surface fixedly connected with articulated seat of oil blanket main part, a plurality of articulated seat is annular array distribution in the inboard of oil blanket main part with the axis of oil blanket main part as the array center, articulated seat's surface articulates through the pivot has the extrusion piece. Through above-mentioned technical scheme, utilize articulated seat to carry out movable mounting to the extrusion piece of being convenient for deflects at the surface of articulated seat. Preferably, the upper end surface of the gravity pipe is fixedly inserted with the surface of the extrusion block, the inner side wall surface of the oil seal main body is fixedly connected with a gas storage ring, and the gas storage ring is in a circular ring shape. Through the technical scheme, the extrusion block is utilized to deflect above the gas storage ring, so that when the extrusion block deflects downwards, the surface of the extrusion block extrudes the surface of the gas storage ring. Preferably, the material of the gas storage ring and the material of the supporting air bag are both fluororubber, and the material of the gravity pipe and the material of the extrusion block are both carbon steel.
