Description

Technical Field

[0001] The utility model relates to the technical field of check bearings, in particular to a one-way check bearing mechanism. Background Art

[0002] The check mechanism in the fishing reel transmission system consists of a ratchet mounted on the transmission system gear rod and connected to it, and a pawl hinged on the main body. The check relationship is achieved by turning the check button. When the angler catches a big fish, the check button must be turned to make the pawl engage the ratchet, limiting the reversal of the rocker arm and preventing the big fish from dragging the fishing line away and escaping, causing fish escape.

[0003] The defect of this check mechanism is that there is a large steering clearance between the pawl and the ratchet that cannot be eliminated, so the bait is easy to deviate from the fishing spot. In order to change this unfavorable factor, the existing technology uses a one-way bearing to replace the ratchet. Because the one-way bearing has high precision and reverse locking without clearance, it can improve the phenomenon of the bait deviating from the fishing spot.

[0004] However, when the existing one-way bearing is in use, the ratchet and pawl structure inside it will be damaged due to the long-term operation of the pawl structure, which will cause it to lose its check function. That is, the one-way check structure has low strength, resulting in poor stability. Utility Model Content
