Description

Sealing ring and fishing reel waterproof structure thereof

Technical Field

The utility model relates to the technical field of a sealing ring and a fishing reel, in particular to a sealing ring and a waterproof structure of the fishing reel.

Background

Spinning reels are widely used because of their advantages such as ease of use and ease of use. When the spinning wheel type fishing line reel is used, the rocker arm is rotated to drive the coaxially arranged fluted disc and the pinion to rotate, the power is divided into two paths to be output, one path is that the fluted disc is meshed with the toothed rod, and the line shell arranged on the toothed rod is driven to rotate, so that the line shell obtains the rotating power. The other path is meshed with the transmission gear through the pinion, and is converted into axial reciprocating motion of the main shaft through the matching of a pin shaft on the transmission gear and a sliding block (the sliding block is fixed on the main shaft), so that the reel arranged on the main shaft makes axial reciprocating motion, namely, the rotation motion of the bobbin is matched with the axial reciprocating motion of the reel, and the uniform wire arrangement of the spinning reel is realized.

In order to realize the wire arrangement, a main shaft in a rack bar is exposed after penetrating through a central hole in the middle of a wire shell, the main shaft at the exposed part is used for installing a wire wheel and other components, and meanwhile, in order to carry out axial limiting, a nut is generally connected to the rack bar after penetrating through the central hole in a threaded manner.

Since the reel is used in a relatively humid environment, moisture is likely to enter the main body along the main shaft at the center hole of the reel housing, and thus there is a possibility that the internal parts are corroded by the moisture. In order to avoid this drawback, a seal ring is often fitted over the spindle outside the nut and is pressed by a pressing cover. However, the sealing effect of the conventional sealing ring is not ideal, and therefore, the conventional sealing ring is still to be further improved.
