Description

Technical Field

[0001] This utility model relates to the field of fishing reel accessories, and in particular to a switching bearing for fishing reels. Background Technology

[0002] A fishing reel, also called a line reel, line feeder, or line reel, is an essential piece of fishing tackle for casting (sea) rod fishing. It typically consists of a handle, crank arm, anti-reverse switch, main body, reel feet, guide reel, line reel, casting nut, hook clip, line housing, drag system, and one-way bearing. It's a retrieval and transmission device fixed to the front of the casting rod handle and forms the core of a casting rig. The one-way bearing in the reel primarily functions as a clutch, enabling one-way transmission. This reduces rotational resistance, provides high torque output, achieves a backlash-free reaction system, and improves the handling experience, thus enhancing overall control and the fishing experience. This component is one of the core components of a fishing reel, especially widely used in high-end spinning reels.

[0003] Currently available one-way bearings with on / off switching function can rotate in both directions. However, the switching part for switching between on and off positions extends from the cage and beyond the outer ring diameter, making it difficult to seal the head of the fishing reel body. This results in poor waterproofing and makes assembly difficult, affecting manufacturability. Therefore, it is necessary to improve existing one-way bearings with switching function. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology and its main objective is to provide a switching bearing for fishing reels. This bearing effectively solves the problem that in existing one-way bearings with switching function, the switching part extends out of the cage and beyond the outer ring diameter, making it difficult to seal the head of the fishing reel body, resulting in poor waterproofing, difficulty in assembly, and affecting its manufacturability.

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

[0006] A switching bearing for a fishing reel includes an outer ring, a cage, an interference module, a cover, and an inner ring. The outer ring has a through groove penetrating its upper and lower surfaces. The inner wall of the through groove has multiple ejector structures arranged circumferentially at intervals. The cage is rotatably mounted on the lower surface of the outer ring and has a first through hole and a switching groove. The first through hole communicates with the through groove. The upper surface of the cage extends upward with multiple extensions, all of which extend into the through groove and surround the periphery of the first through hole. The components are arranged circumferentially at intervals, and mounting positions are formed between adjacent extensions; there are multiple interference modules, each set in a corresponding mounting position; the cover is placed on the outer ring, and the cover has a second through hole that communicates with the through groove; the inner ring has a mounting groove that matches the rack, and the inner ring can be rotatably installed in the through groove and pass through the first and second through holes; when the retainer rotates clockwise to its position, the inner ring rotates bidirectionally in the through groove, and when the retainer rotates counterclockwise to its position, the inner ring rotates unidirectionally in the through groove.

[0007] As a preferred embodiment, the outer ring extends outward to form a mounting portion for assembling and positioning with the main body of the fishing vessel.

[0008] As a preferred embodiment, the plurality of ejector structures extend inward from the inner side of the through groove. When the retainer is rotated counterclockwise into position, the plurality of ejector structures extend into the corresponding mounting position and partially eject the interference module.

[0009] As a preferred embodiment, each interference module includes an elastic element and a needle roller, both of which are located in a corresponding mounting position. One end of the elastic element is in elastic contact with one of the extensions in the corresponding mounting position, one side of the needle roller is in elastic contact with the other end of the elastic element, and the other side of the needle roller abuts against another extension in the corresponding mounting position.

[0010] As a preferred embodiment, the elastic element is a spring.

[0011] As a preferred embodiment, the plurality of extensions all extend into the second through hole through the through groove. The second through hole has a plurality of limiting grooves on its peripheral side. The plurality of limiting grooves are arranged circumferentially at intervals, and the aforementioned plurality of extensions are limited and engaged with the corresponding limiting grooves.

[0012] As a preferred embodiment, the outer diameter of the outer ring is larger than the outer diameter of the cage.

[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 creating a switching groove on the cage, which engages with an external switching rod, the user controls the cage rotation by swinging the switching rod. When rotated clockwise to the desired position, the inner ring rotates bidirectionally within the groove. When rotated counterclockwise to the desired position, the inner ring can only rotate unidirectionally within the groove. This structure provides the bearing with a switchable function without extending any related structures outward. This facilitates the sealing of the head of the fishing reel body, enabling the reel to achieve better waterproof performance, and also facilitates assembly, improving its manufacturability.

[0031] Please refer to Figures 1 to 5As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including an outer ring 10, a retainer 20, an interference module 30, a cover 40, and an inner ring 50.

[0032] The outer ring 10 has a through groove 11 that runs through the upper and lower surfaces of the outer ring. The inner wall of the through groove 11 has a plurality of ejector structures 12, which are arranged circumferentially on the inner wall of the through groove 11. In this embodiment, the outer ring 10 has an assembly part 13 extending outward from its circumferential side for assembly and positioning with the main body of the fishing reel. The plurality of ejector structures 12 extend inward from the inner side of the through groove 11. The outer diameter of the outer ring 10 is larger than the outer diameter of the retainer 20.

[0033] The retainer 20 is rotatably mounted on the lower surface of the outer ring 10. The retainer 20 has a first through hole 21 and a switching groove 22. The first through hole 21 communicates with the through groove 11. The upper surface of the retainer 20 extends upward with a plurality of extensions 23. The plurality of extensions 23 all extend into the through groove 11. The plurality of extensions 23 are arranged circumferentially around the periphery of the first through hole 21, and a mounting position 201 is formed between two adjacent extensions 23.

[0034] There are multiple interference modules 30, and each interference module 30 is respectively disposed in a corresponding mounting position 201. In this embodiment, each interference module 30 includes an elastic element 31 and a needle roller 32. The elastic element 31 and the needle roller 32 are both located in the corresponding mounting position 201. One end of the elastic element 31 is in elastic contact with one of the extensions 23 in the corresponding mounting position 201. One side of the needle roller 32 is in elastic contact with the other end of the elastic element 31. The other side of the needle roller 32 abuts against another extension 23 in the corresponding mounting position 201. The elastic element 31 is a spring.

[0035] The cover 40 is placed on the outer ring 10 and has a second through hole 41 that communicates with the through groove 11. The inner ring 50 has a mounting groove 51 that matches the rack. The inner ring 50 is rotatable in one direction or two directions and is installed in the through groove 11, passing through the first through hole 21 and the second through hole 41. When the retainer 20 rotates clockwise to its position, the inner ring 50 rotates bidirectionally in the through groove 11. When the retainer 20 rotates counterclockwise to its position, the plurality of ejector structures 12 extend into the corresponding mounting positions 201 and partially eject the interference module 30. The inner ring 50 rotates unidirectionally in the through groove 11. In this embodiment, the plurality of extensions 23 extend into the second through hole 41 through the through groove 11. The circumferential side of the second through hole 41 has a plurality of limiting grooves 42. The plurality of limiting grooves 42 are arranged circumferentially at intervals, and the aforementioned plurality of extensions 23 are limited and engaged with the corresponding limiting grooves 42.

[0036] The working principle of this embodiment is described in detail below:

[0037] The user controls the retainer 20 to rotate clockwise via the switching rod. When the retainer 20 is rotated clockwise to its final position, the inner ring 50 can rotate bidirectionally in the through groove 11. The user also controls the retainer 20 to rotate counterclockwise via the switching rod. When the retainer 20 is rotated counterclockwise to its final position, multiple ejector structures 12 extend into their corresponding mounting positions 201 and partially eject the interference module 30. The inner ring 50 then comes into contact with the interference module 30. At this time, when the inner ring 50 rotates clockwise, it interferes with the needle roller 32, causing the needle roller 32 to compress the elastic element 31. After the elastic element 31 is compressed, the inner ring 50 and the needle roller 32 only have slight contact, allowing the inner ring 50 to rotate smoothly clockwise. When the inner ring 50 rotates counterclockwise, it interferes with the needle roller 32. Under mutual compression, the inner ring 50 and the needle roller 32 generate a huge frictional force, preventing the inner ring 50 from rotating counterclockwise in the through groove 11.

[0038] The key design feature of this utility model is:

[0039] By creating a switching groove on the cage, which engages with an external switching rod, the user controls the cage rotation by swinging the switching rod. When rotated clockwise to the desired position, the inner ring rotates bidirectionally within the groove. When rotated counterclockwise to the desired position, the inner ring can only rotate unidirectionally within the groove. This structure provides the bearing with a switchable function without extending any related structures outward. This facilitates the sealing of the head of the fishing reel body, enabling the reel to achieve better waterproof performance, and also facilitates assembly, improving its manufacturability.

[0040] 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.
