Wiper seal reinforcement structure for oil evaporation prevention apparatus

摘要

The present invention is double-extruded polyvinyl chloride reinforcement in the form of wrapping to reinforce the strength of the wiper seal on the outer peripheral surface of the head of the upper part of the contact portion constituting the wiper seal installed in the oil evaporation prevention device mounted inside the oil storage tank. By attaching to the wiper seal, the structure of the wiper seal can be reinforced while simplifying the structure of the wiper seal so as to prevent the wiper seal from coming into contact with the inner wall surface of the oil storage tank to be rolled outward or inward, thereby further increasing the service life of the wiper seal. In addition, the wiper seal can be combined with other parts of the device to reduce the number of parts and used parts during installation, thereby providing a wiper seal reinforcement structure for an oil evaporation prevention device that can reduce the manufacturing cost of the device.;Oil tank, oil evaporation prevention device, wiper seal, tight part, head, reinforcing piece
