Description

Technical Field

[0001] This utility model relates to the field of raft fishing reels, and in particular to a two-way clutch structure for raft fishing reels. Background Technology

[0002] Existing raft fishing reels usually have a clutch mechanism, but the commonly used clutch mechanism uses a retaining spring. However, in use, the retaining spring is locked and must be manually cranked to release it, which only allows for one-way operation and cannot meet the more complex and ever-changing fishing needs. Summary of the Invention

[0003] To solve the technical problem of the aforementioned one-way clutch operation, this utility model provides a clutch structure for a raft wheel.

[0004] The technical solution of this utility model is as follows:

[0005] A two-way clutch structure for a raft wheel includes a main cover and a main body. The main cover is fitted onto the main body. A rocker arm transmission system is provided on both the main cover and the main body. The rocker arm transmission system includes a large gear and a small gear meshing together. The small gear is fitted onto a main shaft, which is movably positioned in the middle of the main cover. A gear sleeve is fitted below the small gear body, and an annular groove is provided on the upper part of the gear sleeve. The main cover has a hollow center, and a circular groove is provided on the inner wall of the hollow center. A ratchet body is provided on the circular groove, and a [missing information - likely a design feature] is provided at the top of the ratchet body. It has a locking pin that is engaged in a circular groove. The lower part of the ratchet body is surrounded by an upper pressure body and a lower pressure body. The inner wall of the ratchet body has a socket. A clutch plate is located below the ratchet body. The clutch shaft passes through the clutch plate and is inserted into the socket. A circular hole is opened on the right side of the clutch plate. Protrusions are provided on both sides of the circular hole. A locking block is located at the lower part of the clutch shaft. A compression spring is provided between the locking block and the clutch plate. An opening is located on the left side of the clutch plate. A clutch groove is provided at the opening. The clutch groove engages with the annular locking groove. The lower end of the clutch shaft passes through the main body and is connected to the clutch lever.

[0006] The upper and lower pressure bodies are connected by a slope, and are spaced apart. The upper and lower pressure bodies are positioned in a cross shape, and the height of the upper pressure body is greater than that of the lower pressure body.

[0007] The protrusion has slopes on both sides, and a smooth surface between the slopes.

[0008] The clutch groove is U-shaped.

[0009] Both the upper and lower ends of the clutch shaft are side-cut. The upper end of the clutch shaft is inserted into the insertion port, and the lower end of the clutch shaft is inserted into the clutch lever hole.

[0010] The clutch shaft and clutch lever are fixed by screws.

[0011] The main body has a protruding mounting base a and a mounting base b at its bottom. A movable groove is left between mounting base a and mounting base b. A limiting plate is fixed on the surface of mounting base a and mounting base b. A limiting hole is hollowed out on the surface of the limiting plate. An L-shaped plate is placed in the movable groove. One end of the L-shaped plate extends into the movable groove. A limiting block is provided at the other end of the L-shaped plate. The L-shaped plate is located below the limiting plate. A baffle is provided below the L-shaped plate. A fixed shaft passes through the baffle and the L-shaped plate and is locked in the limiting hole. A locking hole is provided on one side of the bottom of the baffle. One end of a torsion spring is locked in the locking hole. The other end of the torsion spring is locked on the fixed post. A rod is provided on the upper part of the baffle. The rod is L-shaped. The locking block pushes the L-shaped plate to move outward so that the protrusion a touches the head of the rod of the baffle.

[0012] The lower part of the toothed sleeve is provided with protrusions a on both sides.

[0013] The technical solution of this utility model has a novel structure and a clever and simple design. The clutch lever drives the clutch shaft to rotate, and the rotation of the clutch shaft causes the ratchet body to rotate, so that the lower pressing body moves from between the bosses to the top of the bosses, causing the clutch plate to be squeezed downward. The clutch plate is also subjected to the pressure of the compression spring, which generates a force on the annular groove to achieve the clutch effect. When the clutch lever is turned back, the clutch plate will also return to its original position. It is a two-way clutch structure. In addition, the locking block on the clutch shaft drives the L-shaped plate to move, so that the head of the baffle rod generates resistance against the protrusion a of the toothed sleeve. It is a dual-clutch structure, which is convenient and versatile in operation, and is easy to use. Attached Figure Description
