Description

Technical Field

[0001] The utility model patent relates to the technical field of spinning wheels, and specifically, to a spinning wheel rocker arm structure. Background Art

[0002] Spinning reels are the most common and widespread fishing reels and are widely used in sea fishing, lure fishing, and fishing in lakes and ponds. They are easy to operate and can be operated entirely by feel after becoming proficient in them, without the need for active observation with the eyes. They have excellent characteristics such as low casting resistance and not prone to line tangling.

[0003] The spinning reel rocker is a control device on the spinning reel used to reel in and out the fishing line. The spinning reel rockers currently on the market are mainly composed of a rocker sleeve, a rocker rod and a grip. A rocker sleeve and a grip are respectively provided at both ends of the rocker rod. A rocker core shaft is provided in the rocker sleeve, and the rocker is assembled and connected to the spinning wheel through the rocker core shaft. A rocker rivet is provided in the grip, and the grip is fixed to the rocker rod through the rocker rivet.

[0004] This type of spinning reel rocker has the following problems: due to the size deviation during the production and processing of the grip ball, the inside of the grip ball cannot be completely matched with the rocker arm rivet, which affects the stability of the spinning reel rocker arm. In order to prevent the grip ball from axially moving on the rocker arm rivet, it is necessary to put gaskets of different thicknesses on the rocker arm rivet for adjustment, which is rather troublesome. Moreover, the spinning reel rocker structure on the market, whether it is made of metal or plastic, mostly adopts a pin riveted structure, which has high process cost, high labor cost, and cannot be reduced in weight. Utility Model Content

[0006] The utility model is implemented as follows: a spinning wheel rocker arm structure comprises a carbon rocker arm, a positioning pin, a sleeve and a transmission shaft;

[0007] The carbon rocker arm comprises a gripping portion and a connecting portion which are integrally connected, the connecting portion is provided with a first connecting hole which is axially through, and the end of the transmission shaft passes through the first connecting hole and is connected to the carbon rocker arm;

[0008] A radially arranged pin hole is formed at the end of the transmission shaft, and the end of the transmission shaft is connected to the first connecting hole;

[0009] The carbon rocker arm is also provided with a blind wedge-shaped groove. When the transmission shaft is connected to the carbon rocker arm, the positioning pin passes through the blind wedge-shaped groove and the pin hole in sequence.

[0010] The middle portion of the transmission shaft passes through the sleeve and is connected with the sleeve.

[0011] Furthermore, a second connecting hole arranged axially is opened at the end of the transmission shaft, and a decorative cover is connected to the second connecting hole and covers the right end of the entire connecting portion.

[0012] Furthermore, a connecting protrusion is provided at the end of the connecting portion of the carbon rocker arm, and the outer diameter of the connecting protrusion is smaller than the outer diameter of the end of the connecting portion.

[0013] Furthermore, the sleeve is provided with an axially arranged third connecting hole, the connecting protrusion is placed in the left end of the third connecting hole, the third connecting hole is a stepped hole, and the inner diameter of the connection between the third connecting hole and the connecting protrusion is larger than the rest of the third connecting hole, and the right end of the third connecting hole is provided with an internal thread.

[0014] Furthermore, the middle end of the transmission shaft is provided with an external thread, and the end of the transmission shaft passes through the first connecting hole.

[0015] Furthermore, the middle end of the transmission shaft is threadedly connected to the right end of the third connecting hole, and the head end of the transmission shaft passes through the sleeve and extends to the outside of the sleeve.

[0016] Compared with the prior art, the carbon rocker arm, transmission shaft and sleeve of the utility model are connected by threads.
