Description

Technical Field

[0001] The utility model relates to the technical field of fishing reels, in particular to a connecting structure of a fishing reel rocker arm. Background Art

[0002] A fishing reel, also known as a fishing line reel, a wire dispenser, a line winder, anciently called a fishing cart, is one of the essential fishing tackle for casting (sea) rod fishing. It is usually a wire winding transmission device composed of 11 main components such as a crank, a rocker arm, a reverse stop button, a main body, a wheel foot, a guide wheel, a line wheel, a casting line nut, a hook line clip, a line case, and a drag device. It is a fishing tackle fixed in front of the handle of the casting rod and is the main fishing tackle constituting the casting rod fishing set. Basically, fishing reels are divided into two major categories: a drum type reel with the wire laying direction parallel to the wire entering and leaving direction, and a spinning reel with the wire laying direction perpendicular to the wire entering and leaving direction.

[0003] In the existing fishing reels, the rocker arm of the fishing reel is connected to the internal sprocket shaft by screwing. When reeling in the line, it is necessary to drive the sprocket shaft to rotate through the rocker arm. At this time, the thread between the rocker arm and the sprocket shaft will become tighter and tighter, resulting in a large pressing force on the end face of the sprocket shaft. At the same time, the thrust of the rocker arm in the axial direction of the sprocket shaft will also be transmitted to the end of the sprocket shaft, which will cause the end of the sprocket shaft to bulge outwards, making it impossible to remove the bearing installed on the sprocket shaft during maintenance, affecting the maintenance process. After long-term use, the sprocket shaft will also be damaged, affecting the overall service life of the rocker arm. Therefore, it is necessary to further improve the existing rocker arm structure. Content of the Utility Model

[0004] In view of this, aiming at the deficiencies existing in the prior art, the main purpose of the utility model is to provide a connecting structure of a fishing reel rocker arm, which can effectively solve the problems that the existing fishing reel rocker arm is prone to squeezing the sprocket shaft during rotation, inconvenient maintenance process, and short overall service life.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A connecting structure of a fishing reel rocker arm includes a body, a toothed rod, a transmission member, and a rocker arm; there is an installation cavity inside the body; the toothed rod is rotatably arranged on the body and located in the installation cavity, and the outer end of the toothed rod extends out of the body; the transmission member includes a transmission shaft and a sprocket; the transmission shaft is rotatably arranged on the body and located in the installation cavity, and a conical surface is provided on the end face of the connecting end of the transmission shaft. The sprocket is arranged on the transmission shaft and rotates back and forth with the transmission shaft. The sprocket is in fit connection with the inner end of the toothed rod and drives the toothed rod to rotate back and forth; the rocker arm includes a connecting shaft and a main body. The inner end of the connecting shaft extends into the installation cavity and is in screwed connection with one end of the transmission shaft. A conical groove matching with the conical surface is provided at the inner end of the connecting shaft, and one end of the main body is fixedly connected to the outer end of the connecting shaft.

[0007] As a preferred solution, the rack is mounted and connected to the inner side wall of the installation cavity through a first bearing.

[0008] As a preferred solution, the transmission shaft is integrally formed with the gear disk, and both ends of the transmission shaft are respectively mounted and connected to the inner side wall of the installation cavity through second bearings.

[0009] As a preferred solution, a contact portion corresponding to the end face of the connection end of the transmission shaft is integrally convexed outward on the connection shaft, and the conical groove is integrally recessed inward from the side wall of the contact portion facing the transmission shaft.

[0010] As a preferred solution, the main body includes a connecting arm and a handle. One end of the connecting arm is fixedly connected to the outer end of the connection shaft, and the handle is hinged to the other end of the connecting arm.

[0011] As a preferred solution, the rocker arm further includes a sleeve, and the sleeve is arranged on the main body and sleeved on the part of the connection shaft exposed from the main body.

[0012] As a preferred solution, a bushing is arranged on the connection shaft, and the conical groove is integrally recessed inward from the side wall of the bushing close to the transmission shaft.

[0013] As a preferred solution, the bushing is fixed on the connection shaft by screwing.

[0014] Compared with the prior art, the present utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solutions that:

[0015] A conical surface is arranged on the end face of the connection end of the transmission shaft, and the inner end of the connection shaft extends into the installation cavity and is screwed to one end of the transmission shaft. A conical groove matching the conical surface is arranged at the inner end of the connection shaft. Through the cooperation of the conical groove and the conical surface, the pressing force of the rocker arm on the gear disk shaft is divided into a radial force towards the center of the gear disk shaft, thereby reducing the pressing force on the gear disk shaft and avoiding the swelling of the outer side of the gear disk shaft. During subsequent maintenance, the bearing on the gear disk shaft can be smoothly taken out, and the gear disk shaft will not be damaged even after long-term use, effectively extending the overall service life.

[0036] The rocker arm 40 includes a connecting shaft 41 and a main body 42. The inner end of the connecting shaft 41 extends inwardly into the mounting cavity 101 and is threadedly connected to one end of the transmission shaft 31. The inner end of the connecting shaft 41 is provided with a tapered groove 401 that cooperates with the tapered surface 311. Through the cooperation between the tapered surface 311 and the tapered groove 401, the axial pressing force of the rocker arm 40 on the transmission shaft 31 is shared as a force toward the radial center of the transmission shaft 31, thereby avoiding the situation where the side wall of the gear plate 31 swells outward due to the pressing force. One end of the main body 42 is fixedly connected to the outer end of the connecting shaft 41. In this embodiment, the connecting shaft 41 is integrally provided with a contact portion 43 that corresponds to the end face of the connecting end of the transmission shaft 31, and the tapered groove 401 is integrally formed by the contact portion 43 being concavely formed inwardly toward the side wall of the transmission shaft 31.

The rocker arm 40 also includes a sleeve 44, which is arranged on the main body 42 and covers the portion of the connecting shaft 41 exposed from the body 10, thereby protecting the connecting shaft 41.

[0037] Please refer to Figures 4 to 5 As shown, it shows the specific structure of the second preferred embodiment of the utility model, which is basically the same as the structure of the first preferred embodiment mentioned above, and the difference is:

[0038] In this embodiment, a bushing 45 is provided on the connecting shaft 41, and the tapered groove 401 is formed by the side wall of the bushing 45 close to the transmission shaft 31, so that only one bushing 45 needs to be installed on the connecting shaft 41, and there is no need to re-open the mold for the tapered groove 401, which effectively reduces the processing cost. The bushing 45 is fixed on the connecting shaft 41 by screwing.

[0039] The design focus of the present utility model lies in that: a conical surface is provided on the end face of the connection end of the transmission shaft, and the inner end of the connection shaft extends inward into the installation cavity and is screwed to one end of the transmission shaft. A conical groove matching with the conical surface is provided at the inner end of the connection shaft. Through the cooperation of the conical groove and the conical surface, the pressing force of the rocker arm on the gear disc shaft is shared into a radial force towards the center of the gear disc shaft, thereby reducing the pressing force on the gear disc shaft and avoiding the swelling of the outer side of the gear disc shaft. During subsequent maintenance, the bearing on the gear disc shaft can be smoothly removed, and the gear disc shaft will not be damaged even after long-term use, effectively extending the overall service life.

[0040] The above is only a preferred embodiment of the present utility model, and does not impose any limitation on the technical scope of the present utility model. Therefore, any minor modification, equivalent change and modification made to the above embodiment based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
