Description

Technical Field

[0001] This utility model relates to the field of fishing reels, and in particular to a durable two-shaft fishing reel structure. Background Technology

[0002] A fishing reel, also called a line reel, line feeder, or line reel, is an essential fishing tackle for casting rod fishing. It typically consists of 11 main components, including a handle, crank arm, anti-reverse button, main body, reel feet, guide reel, line reel, casting nut, hook clip, line housing, and drag device. It is a fishing tackle fixed in front of the casting rod handle and is the main tackle that makes up a casting rod fishing rig.

[0003] Two-axis fishing reels are common, using gears for power transmission. Currently, the market is constantly pursuing lighter or smaller reels, while simultaneously demanding higher strength. However, under heavy loads or after prolonged use, the gears of two-axis reels are prone to bending, deformation, or wear, leading to a decrease in reel feel and even shortening the reel's lifespan. Therefore, it is necessary to improve existing two-axis fishing reels. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide a durable two-shaft fishing reel structure that can effectively solve the problem that the gears of existing two-shaft fishing reels are prone to bending and deformation or wear under heavy loads or after long-term use, resulting in a decrease in the feel of the fishing reel and even a shortened service life.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A durable two-shaft fishing reel structure includes a main body, a gear rod, a reel, a gear disc shaft, and a gear disc. The gear rod is rotatably mounted on the main body. The reel is mounted on the gear rod and drives it to rotate. The gear disc shaft is mounted on the main body. The gear disc is rotatably mounted on the gear disc shaft and meshes with the gear rod. One end of the gear rod is a transmission part, and the peripheral side of the transmission part is provided with a plurality of circumferentially spaced first teeth. One side of each first tooth is a first working surface, and a first reinforcing part is provided on the first working surface. The gear disc includes an integrally formed gear disc body and second teeth. The second teeth are provided on the peripheral side of the gear disc body, and there are a plurality of circumferentially spaced second teeth. One side of each second tooth is a second working surface, and a second reinforcing part is provided on the second working surface. When the gear rod meshes with the gear disc, each first working surface contacts the corresponding second working surface, and each first reinforcing part contacts the corresponding second reinforcing part.

[0007] As a preferred embodiment, the main body has a storage space, the rack passes through the storage space, the transmission part extends out of the main body, and the reel is located inside the storage space.

[0008] As a preferred embodiment, the toothed disc is rotatably mounted on the toothed disc shaft and located outside the body, and the toothed disc meshes with the toothed bar.

[0009] As a preferred embodiment, the other side of each first tooth is a first non-working surface. The angle α formed by the first working surface and the outer end face of the first tooth is greater than the angle β formed by the first non-working surface and the outer end face of the first tooth to form the aforementioned first reinforcing part. The conventional tooth design is symmetrical, while this design is asymmetrical. It can also make the pressure angle at the connection between the first working surface and the peripheral side of the transmission part larger. The larger the pressure angle at this position, the smaller the stress, which effectively reduces the stress at the connection between the first working surface and the peripheral side of the transmission part, so that the first working surface can withstand greater strength without deformation or breakage, thereby increasing the strength of the first working surface.

[0010] As a preferred embodiment, the transmission unit is an involute gear structure.

[0011] As a preferred embodiment, the other side of each second tooth is a second non-working surface. The angle γ formed by the second working surface and the outer end face of the second tooth is greater than the angle θ formed by the second non-working surface and the outer end face of the second tooth to form the aforementioned second reinforcing part. The conventional tooth design is symmetrical, while this design is asymmetrical. It also allows for a larger pressure angle at the connection between the second working surface and the peripheral side of the tooth disc body. The larger the pressure angle at this position, the smaller the stress, effectively reducing the stress at the connection between the first working surface and the peripheral side of the tooth disc body. This allows the second working surface to withstand greater strength without deformation or breakage, thereby increasing the strength of the second working surface.

[0012] As a preferred embodiment, the gear disk is an involute gear structure.

[0013] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0014] By providing a first reinforcing part on the first working surface and a second reinforcing part on the second working surface, the first and second reinforcing parts respectively increase the strength of the first and second teeth. In addition, when the rack and the gear plate mesh and drive, each first reinforcing part contacts the corresponding second reinforcing part. Since the strength of the teeth is improved, the teeth are not prone to bending deformation and tooth surface wear under heavy load or after long-term use. The feel of the fishing reel will not decrease, effectively extending the service life of the fishing reel.

[0029] Please refer to Figures 1 to 4 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including a main body 10, a rack 20, a spool 30, a gear shaft 40, and a gear 50.

[0030] The main body 10 has a storage space 11.

[0031] The rack 20 is rotatably mounted on the main body 10. One end of the rack 20 is a transmission part 21. The peripheral side of the transmission part 21 is provided with a plurality of circumferentially spaced first teeth 22. One side of each first tooth 22 is a first working surface 221, and a first reinforcing part 222 is provided on the first working surface 221. In this embodiment, the rack 20 passes through the storage space 11, and the transmission part 21 extends out of the main body 10. Specifically, the other side of each first tooth 22 is a first non-working surface 223. The angle α formed by the first working surface 221 and the outer end face of the first tooth 22 is greater than the angle β formed by the first non-working surface 223 and the outer end face of the first tooth 22 to form the aforementioned first reinforcing part 222. The traditional tooth design is symmetrical, but this design is asymmetrical and allows the first working tooth 222 to be reinforced. The pressure angle at the connection between the first working surface 221 and the peripheral side of the transmission part 21 is larger. The larger the pressure angle at this position, the smaller the stress, which effectively reduces the stress at the connection between the first working surface 221 and the peripheral side of the transmission part 21. This allows the first working surface 221 to withstand greater strength without deformation or breakage, thereby increasing the strength of the first working surface 221. The structure of the first reinforcing part 222 can be varied. It can be a protrusion formed by the outward projection of the first working surface 221. When the pressure angle between the first non-working surface 223 and the peripheral side of the transmission part 21 is the same as the pressure angle between the first working surface 221 and the peripheral side of the transmission part 21, the first reinforcing part 222 can be an arc-shaped surface. The arc shape can effectively buffer the internal stress of the material, reduce the internal stress of the material, and achieve the effect of increasing strength. The transmission part 21 is an involute gear structure.

[0032] The reel 30 is mounted on the rack 20 and drives the rack 20 to rotate; in this embodiment, the reel 30 is located in the storage space 11.

[0033] The gear shaft 40 is mounted on the main body 10.

[0034] The gear disk 50 is rotatably mounted on the gear disk shaft 40 and meshes with the rack 20. The gear disk 50 includes an integrally formed gear disk body 51 and second tooth portions 52. The second tooth portions 52 are disposed on the peripheral side surface of the gear disk body 51. Multiple second tooth portions 52 are arranged circumferentially at intervals. One side surface of each second tooth portion 52 is a second working surface 521. A second reinforcing portion 522 is provided on the second working surface 521. When the rack 20 meshes with the gear disk 50, each first working surface 521... 21 contacts the corresponding second working surface 521, and each first reinforcing part 221 contacts the corresponding second reinforcing part 522; in this embodiment, the gear disk 50 is rotatably mounted on the gear disk shaft 40 and located on the outside of the main body 10, and the gear disk 50 meshes with the gear rack 20; the other side of each second tooth 52 is a second non-working surface 523, and the included angle γ formed by the second working surface 521 and the outer end face of the second tooth 52 is greater than the angle γ between the second non-working surface 523 and the outer end face of the second tooth 52. The included angle θ formed by the end face forms the aforementioned second reinforcing part 522. The traditional tooth design is symmetrical, but this design is asymmetrical, which allows for a larger pressure angle at the connection between the second working surface 521 and the peripheral side of the gear disk body 51. The larger the pressure angle at this position, the smaller the stress, effectively reducing the stress at the connection between the second working surface 522 and the peripheral side of the gear disk body 51. This allows the second working surface 522 to withstand greater strength without deformation or breakage, thereby increasing the strength of the second working surface 522. The structure of the second reinforcing part 522 can be varied. It can be a protrusion formed by the outward projection of the second working surface 521. When the pressure angle between the second non-working surface 523 and the peripheral side of the gear disk body 51 is the same as the pressure angle between the second working surface 521 and the peripheral side of the gear disk body 51, the second reinforcing part 522 can be an arc-shaped surface. The arc shape can effectively buffer the internal stress of the material, reduce the internal stress of the material, and achieve the effect of increasing strength. The gear disk 50 is an involute gear structure.

[0035] The key design feature of this invention is that by providing a first reinforcing part on the first working surface and a second reinforcing part on the second working surface, the first and second reinforcing parts respectively increase the strength of the first and second teeth. Furthermore, when the rack and the gear plate mesh, each first reinforcing part contacts the corresponding second reinforcing part. Because the strength of the teeth is improved, the teeth are less prone to bending deformation and tooth surface wear under heavy loads or after long-term use, and the feel of the fishing reel will not decrease, effectively extending the service life of the fishing reel.

[0036] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
