Description

Technical Field

[0001] This utility model relates to the field of fishing gear technology, and in particular to a left-right adjustable clutch structure. Background Technology

[0002] In the field of fishing tackle technology, the fishing reel is one of the most crucial pieces of equipment in fishing, and its performance directly affects the angler's fishing experience and results. With the popularization and development of fishing, anglers have placed increasingly higher demands on the ease of operation, functionality, and reliability of fishing reels.

[0003] Traditional fishing reels have many limitations in their structural design. Regarding left- and right-handed adaptability, most reels are designed for right-handed use, making them extremely inconvenient for left-handed anglers. This single-handed design limits the comfort and efficiency for some users, as left-handed anglers find it difficult to naturally apply force and precisely control the reeling and releasing of line when using a right-handed reel, leading to operational errors and affecting fishing results.

[0004] In terms of clutch mechanism, traditional fishing reel clutch systems have significant shortcomings. The clutch action is not sensitive enough. When anglers need to quickly switch the reel's transmission state, such as when adjusting retrieval resistance or releasing line the instant a fish bites, traditional clutch mechanisms often react slowly, failing to meet the angler's need for immediate operation. Furthermore, the slow clutch rebound speed means that during frequent retrieval and release operations, the reel cannot quickly return to its initial state, easily causing the fishing line to slack or jam, thus affecting line tension control and increasing the risk of fish getting off the hook or the line becoming tangled.

[0005] Furthermore, traditional fishing reels are not compact in structure and have an unreasonable layout of internal components. This not only results in a large and heavy overall size, making them inconvenient to carry and operate, but also reduces the utilization of internal space and limits the optimized design of other functional components. At the same time, the fit between components is not precise enough, and problems such as wear and loosening are prone to occur during long-term use, reducing the reliability and service life of the fishing reel and increasing maintenance costs and frequency.

[0006] In conclusion, existing fishing reel technology has many problems in terms of ease of operation with both left and right hands, clutch performance, and overall structural design. There is an urgent need for an innovative structure to solve these problems, meet the growing needs of anglers, and improve the overall performance of fishing reels. Utility Model Content

[0007] This utility model aims to provide a left-right adjustable and matching clutch structure. Through innovative design, it not only realizes convenient switching between left- and right-hand operation of the drum, but also optimizes the clutch function, improves the flexibility, reliability and efficiency of fishing reel operation, meets the needs of different users, and enhances the performance of the equipment under various working conditions.

[0008] (I) Two-way anti-reverse ratchet structure

[0009] Two-way backstop design

[0010] The two-way backstop plate abandons the traditional serrated design and adopts a brand-new triangular design that symmetrically supports the backstop pawl. This unique shape provides a stable and symmetrical support area for the backstop pawl, forming an effective backstop zone. The triangular structure allows the backstop pawl to interact accurately with the backstop plate during bidirectional rotation, ensuring the stability and reliability of unidirectional rotation.

[0011] The anti-reverse pawl and the anti-reverse torsion spring work together.

[0012] The anti-reverse pawl has a special anti-reverse angle structure on both sides. The anti-reverse torsion spring works closely with the anti-reverse pawl, and its main functions are reflected in two aspects. First, it changes the direction of torque. When it is necessary to switch the rotation direction of the drum, the anti-reverse torsion spring can apply appropriate torque to make the anti-reverse pawl rotate around the axis. For example, when switching from the initial clockwise unidirectional rotation mode to the counterclockwise unidirectional rotation mode, the anti-reverse torsion spring provides counterclockwise torque, causing the anti-reverse angle of the anti-reverse pawl to disengage from the current clockwise anti-reverse range.

[0013] Secondly, it features a slight rebound function. During the rotation of the anti-reverse pawl, the slight rebound characteristic of the anti-reverse torsion spring ensures that the anti-reverse pawl will not rotate excessively, guaranteeing that it can accurately position the other side's anti-reverse angle within the corresponding anti-reverse range. This precise positioning allows the drum to smoothly achieve unidirectional rotation (clockwise and counterclockwise) with both hands, and remains stable during rotation, effectively preventing reverse rotation and improving the safety and controllability of drum operation.

[0014] (II) Drum clutch and spring-loaded structure

[0015] Unique design of clutch insert

[0016] The clutch insert features symmetrical bosses with a carefully designed engagement angle. This unique design allows the clutch insert to produce specific mechanical effects when interacting with the clutch ratchet. Under the action of the clutch torsion spring, the clutch insert can switch to two extreme positions in the vertical direction: "top dead center" and "bottom dead center." The switching between these two positions is crucial for the realization of clutch action.

[0017] The working mechanism of clutch ratchet plate and clutch torsion spring

[0018] The clutch ratchet plate has a clutch boss. When the drum rotates left and right, the clutch ratchet plate rotates accordingly, and the clutch boss applies a helical torque to the clutch insert plate. When the drum rotates clockwise, the torque generated by the clutch boss overcomes the initial torque of the clutch torsion spring, causing the clutch insert plate to lift upwards, thus completing one clutch action. Similarly, when the drum rotates counterclockwise, the clutch boss acts in a similar manner, causing the clutch insert plate to move accordingly, achieving the clutch function.

[0019] The clutch torsion spring plays a crucial role in reversing and returning to its original position throughout the process. After the clutch action is completed, the clutch torsion spring quickly changes the direction of torque, rapidly pulling the clutch plate back to its initial position (such as "bottom dead center"), preparing for the next clutch operation. Its rapid return characteristic ensures the continuity and timeliness of the clutch action, enabling the drum to quickly and accurately perform clutch operations according to actual needs during rotation, ensuring stable and efficient power transmission of the equipment.

[0020] Beneficial effects

[0021] 1. Ability to switch flexibly between left and right hands

[0022] The two-way anti-reverse ratchet mechanism allows the fishing reel to be easily adapted to both left- and right-handed operation. Anglers can quickly switch the direction of operation of the reel according to their own habits in different fishing scenarios, without the need to change or adjust complex parts. This is especially important for left-handed anglers, who can operate the fishing reel as freely as right-handed anglers, improving accuracy and comfort, and reducing errors caused by unfamiliarity with the operation. For example, they can better control the force and direction during casting and reeling, increasing the success rate of catching fish.

[0023] 2. In certain specialized fishing techniques, such as when quickly switching between reeling in and letting out line, the structure of this invention allows anglers to rapidly change the rotation direction of the reel, better responding to unexpected situations such as fish escaping or biting the hook. Whether in freshwater or saltwater fishing, different fish species and fishing environments may require different operating methods. The ambidextrous adjustment function of this invention provides anglers with more operational options, enhancing the enjoyment and efficiency of fishing.

[0024] 3. The design of the drum reel's clutch rebound structure ensures the sensitivity and precision of the clutch action. The precise cooperation between the clutch insert plate and the clutch ratchet plate allows the clutch action to occur accurately even with slight changes in the rotation of the fishing reel. During fishing, when a fish bites, the angler needs to quickly adjust the clutch state of the fishing reel. This new clutch structure can respond promptly, achieving smooth line reeling and unreeling, and avoiding situations where the fishing line breaks or the fish gets off the hook due to untimely clutch engagement.

[0025] 4. The rapid return characteristic of the clutch torsion spring provides strong support for the continuous operation of the fishing reel. During frequent retrieval and release, the clutch plate can quickly return to its initial state, ensuring the timeliness and accuracy of the next clutch action. This allows the fishing reel to maintain stable performance during operation, with the fishing line always at a suitable tension. Whether retrieving quickly or releasing slowly, it ensures smooth line movement, reduces the occurrence of problems such as line tangling, and improves the fishing experience.

[0026] 5. The entire left-right adjustable mechanism and its matching clutch are compactly and rationally arranged within the fishing reel, seamlessly integrating with other components. The integrated design of the two-way backstop ratchet and drum clutch spring mechanism not only avoids increasing the reel's size and weight but also improves its overall performance by optimizing internal space utilization. The compact structure makes the reel more aesthetically pleasing and easier to carry and operate during use.

[0027] 6. Due to the precise fit between components and the selection of high-quality materials, the clutch structure of this invention exhibits excellent reliability during long-term use of the fishing reel. Components such as the two-way anti-reverse plate and anti-reverse pawl are made of wear-resistant materials, capable of withstanding frequent friction and tension from the fishing line during retrieval and release. The optimized design of components such as the clutch insert, clutch ratchet, and clutch torsion spring reduces wear and fatigue between parts, extending the service life of the fishing reel. Even in harsh fishing environments, such as wet, muddy waters, the clutch structure of this invention maintains stable performance, reducing the occurrence of fishing activities affected by equipment malfunctions.

[0028] In summary, this utility model, applied to the left-right adjustable fishing gear and its matching clutch structure, has achieved significant progress in terms of ease of operation, clutch performance, and structural reliability through innovative design and the coordinated work of various components. It provides strong technical support for improving the performance of fishing reels and other fishing gear, greatly enhancing the angler's user experience, and has broad application prospects and important practical value in the fishing gear field.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0036] The present invention provides a left-right adjustable clutch structure, including a fixed plate 01, a clutch insert plate 02, an E-type retaining ring 03, a clutch torsion spring 04, a main shaft 05, a clutch ratchet plate 06, a two-way backstop plate 07, a backstop torsion spring 08, a backstop pawl 09, and a backstop plate screw 10. The two-way backstop plate 07 has a symmetrical triangular design to accommodate the two backstop angles on both sides of the backstop pawl 09.

[0037] The anti-reverse torsion spring 08 achieves slight rebound and direction switching of the anti-reverse pawl 09 by changing the direction of the torque, so that the two sides of the anti-reverse angle of the anti-reverse pawl 09 enter the anti-reverse range of the bidirectional anti-reverse plate 07 respectively, and achieves positioning in the clockwise or counterclockwise direction.

[0038] The clutch insert plate 02 is provided with symmetrical bosses, and the upper dead point and lower dead point in the vertical direction are controlled by the torque of the clutch torsion spring 04.

[0039] The clutch ratchet plate 06 has a clutch boss that applies torque in the rotation direction of the main shaft 05 to push the clutch insert plate 02 upward to complete the clutch action, and quickly resets through the clutch torsion spring 04.

[0040] The E-type retaining ring 03 is installed on the fixed plate 01 and cooperates with the clutch insert 02 to guide and limit the movement, while preventing the clutch insert 02 from slipping off during the up and down sliding process.

[0041] Specifically, the backstop pawl 09 can freely switch between clockwise and counterclockwise directions through the slight rebound of the backstop torsion spring 08, thus adapting to the operating needs of left- and right-handed users. The clutch insert 02 and clutch ratchet plate 06, through their uniquely designed clutch angles, can complete efficient clutch actions regardless of the rotation direction of the spindle 05. The symmetrical triangular design of the bidirectional backstop plate 07 and backstop pawl 09 enhances the structural strength and service life of the device, while ensuring positioning accuracy. The fixing plate 01 is an integral structure with multiple mounting holes for positioning and fixing of various components.

[0042] Example 1, referring to Figures 1 to 4 ,

[0043] This utility model, "an adjustable left-right clutch structure," mainly consists of two parts: a bidirectional backstop ratchet structure and a drum clutch spring-loaded structure. The bidirectional backstop ratchet structure includes a bidirectional backstop plate 07, a backstop torsion spring 08, a backstop pawl 09, and a backstop plate screw 10; the drum clutch spring-loaded structure includes a clutch insert plate 02, a clutch torsion spring 04, a clutch ratchet plate 06, and a main shaft 05.

[0044] II. Implementation Method of the Two-Way Reverse Ropeway Structure

[0045] Component installation and initial state

[0046] First, the double-acting backstop 07 is fixed in the corresponding position using backstop screws 10 to ensure stable installation. The backstop pawl 09 is installed in a position that can interact with the double-acting backstop 07, and the backstop torsion spring 08 is installed in conjunction with the backstop pawl 09 to provide initial torque to the backstop pawl 09.

[0047] In the initial state, the anti-reverse torsion spring 08 keeps the anti-reverse pawl 09 in a relatively stable position, with one side of its anti-reverse angle close to the edge of the anti-reverse interval of the bidirectional anti-reverse plate 07, but not yet fully engaged.

[0048] The process of achieving unidirectional rotation by switching between left and right hands.

[0049] When it is necessary to change the rotation direction of the drum from right-hand operation to left-hand operation, that is, from clockwise rotation to counterclockwise rotation, the anti-torsion spring 08 begins to function.

[0050] The anti-torsion spring 08 changes the direction of the torque, applying a force to the anti-reverse pawl 09, causing it to rotate counterclockwise (assuming an initial clockwise unidirectional rotation). Under this torque, the anti-reverse pawl 09 begins to rotate, and its anti-reverse angle gradually moves away from the anti-reverse range currently rotating clockwise on the bidirectional anti-reverse plate 07.

[0051] Meanwhile, the slight rebound characteristic of the anti-reverse torsion spring 08 ensures that the anti-reverse pawl 09 will not rotate excessively during disengagement. When the anti-reverse pawl 09 rotates to a certain angle, the rebound force of the anti-reverse torsion spring 08 causes the other side of the anti-reverse angle of the anti-reverse pawl 09 to accurately enter the counterclockwise rotation anti-reverse range of the double-sided anti-reverse plate 07. At this point, the drum wheel realizes the conversion from clockwise unidirectional rotation to counterclockwise unidirectional rotation, thus completing the conversion between left- and right-handed operation.

[0052] During clockwise rotation of the drum in right-hand operation mode, the anti-reverse pawl 09, under the action of the anti-reverse torsion spring 08, has its anti-reverse angle firmly locked within the forward anti-reverse range of the double-sided anti-reverse plate 07, preventing the drum from rotating counterclockwise. Similarly, in left-hand operation mode, when rotating counterclockwise, the anti-reverse angle on the other side of the anti-reverse pawl 09 is locked within the corresponding anti-reverse range, preventing clockwise rotation.

[0053] III. Implementation Method of Drum Clutch Rebound Structure

[0054] Component installation and initial state

[0055] The clutch insert plate 02 is mounted on the main shaft 05. The clutch torsion spring 04 is installed in conjunction with the clutch insert plate 02 to provide initial torque and place it in an initial position such as "top dead center" or "bottom dead center". The clutch ratchet plate 06 is installed in a position that can interact with the clutch insert plate 02 and is connected to the rotating part of the drum.

[0056] In the initial state, the clutch insert plate 02 is in a stable position under the action of the clutch torsion spring 04, and the relative positional relationship between its symmetrical boss and the clutch ratchet plate 06 means that the clutch action has not yet occurred.

[0057] The operation process of clutch engagement and springback reset

[0058] When the drum starts to rotate, whether clockwise or counterclockwise, the clutch ratchet plate 06 rotates along with the drum. Due to the design of the clutch boss on the clutch ratchet plate 06 and the unique clutch angle of the clutch insert plate 02, the clutch boss on the clutch ratchet plate 06 will apply a rotational torque to the clutch insert plate 02 during rotation.

[0059] This helical torque overcomes the initial torque of the clutch torsion spring 04, causing the clutch insert 02 to lift upwards, assuming the initial state is the bottom dead center, thus completing one clutch engagement / disengagement action. At this time, the connection state between the drum and related transmission components changes; for example, it may achieve the separation or engagement of some transmission, depending on the design requirements of the entire device.

[0060] As the drum continues to rotate, after the clutch boss passes the point of action of the clutch insert 02, the clutch insert 02 quickly returns to its original position under the directional torque of the clutch torsion spring 04. The rapid rebound characteristic of the clutch torsion spring 04 ensures that the clutch insert 02 can quickly return to its initial state, such as returning to the "bottom dead center," ready for the next clutch action. In this way, during the continuous rotation of the drum, the clutch rebound structure can continuously perform clutch actions and reset operations, ensuring the normal operation of the entire equipment.

[0061] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
