Abstract
The utility model relates to a skeleton oil blanket stop device, including skeleton oil blanket, axle and frame, the frame is equipped with the through-hole, the through-hole is passed to the axle, the skeleton oil blanket is installed inside the through-hole, the inside butt of one end and the through-hole of skeleton oil blanket, the other end fixed connection clamp plate of skeleton oil blanket, be equipped with the spring between clamp plate and the through-hole is inside, the one end of the articulated ejector pin of clamp plate, the other end butt oil blanket lip upper portion of ejector pin. The utility model has the advantages that: when the axial movement happens, the framework oil seal can be pushed to extrude the through hole, so that the pressing plate is stressed, the lip part of the framework oil seal is extruded by the pressing plate through the ejector rod, and the sealing performance of the framework oil seal is improved.
Description
Technical Field
The utility model relates to a skeleton oil blanket especially relates to a skeleton oil blanket stop device.
Background
The framework oil seal is a typical representative of the oil seal, and the oil seal is generally referred to as the framework oil seal. The oil seal generally serves to isolate the components to be lubricated from the external environment, so as not to allow the lubricating oil to leak. The framework acts as a reinforcement for the steel bars inside the concrete member and allows the oil seal to maintain shape and tension. According to the structural form, the single-lip framework oil seal and the double-lip framework oil seal can be separated. The auxiliary lip of the double-lip framework oil seal plays a dustproof role, and prevents external dust, impurities and the like from entering the machine. The framework type oil seal can be divided into an inner-wrapped framework oil seal, an exposed framework oil seal and an assembled oil seal. It can be divided into rotary skeleton oil seal and reciprocating skeleton oil seal according to working condition. The crankshaft is used for gasoline engines, diesel engines, gearboxes, differentials, shock absorbers, engines, axles and the like. The framework oil seal in the prior art can lose efficacy gradually due to reasons such as abrasion, and therefore the service life of the framework oil seal needs to be prolonged.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome exist among the prior art not enough, provide a skeleton oil blanket stop device.
The utility model discloses a realize through following technical scheme:
the utility model provides a skeleton oil blanket stop device, includes skeleton oil blanket, axle and frame, the frame is equipped with the through-hole, the through-hole is passed to the axle, the skeleton oil blanket is installed inside the through-hole, the inside butt of one end and the through-hole of skeleton oil blanket, the other end fixed connection clamp plate of skeleton oil blanket, be equipped with the spring between clamp plate and the through-hole is inside, the one end of the articulated ejector pin of clamp plate, the other end butt oil blanket lip upper portion of ejector pin.
According to the above technical scheme, preferably, the outer fringe of clamp plate is equipped with the recess, through-hole inside is equipped with the slide, the recess is installed outside the slide.
According to the technical scheme, preferably, the pressing plate is hinged with a plurality of ejector rods, and the ejector rods are uniformly distributed on the pressing plate.
According to the technical scheme, preferably, the ejector rods are hinged to the top ring, a groove is formed in the upper portion of a lip opening of the framework oil seal, and the top ring is installed in the groove.
The utility model has the advantages that: when the axial movement happens, the framework oil seal can be pushed to extrude the through hole, so that the pressing plate is stressed, the lip part of the framework oil seal is extruded by the pressing plate through the ejector rod, and the sealing performance of the framework oil seal is improved.
