Abstract
Description
Technical Field
[0001] This application relates to the field of fishing reel technology, and more specifically, to a backstop structure for fishing reels. Background Technology
[0002] Fishing, as a popular outdoor sport, has seen a continuous expansion in its participation in recent years. The fishing reel is a core component of fishing gear, and among them, the internal fishing reel, with its ease of operation, is gradually becoming the mainstream development direction. This type of fishing reel is small in size and compact in structure, which places higher demands on the overall design precision, especially on the precision required for the fit between the various internal components.
[0003] In the design of concealed fishing reels, the anti-backflow mechanism plays a crucial role in fishing activities. Currently, most concealed fishing reels on the market suffer from complex structures and numerous parts, directly contributing to high overall costs. These issues not only necessitate high assembly precision but also directly affect the stability of the reel's operation, making it prone to jamming due to angular deviations, thus impacting the smoothness of forward and reverse rotation. Furthermore, prolonged use can lead to ratchet teeth loosening and falling off, causing the anti-backflow function to fail. Utility Model Content
[0004] To address the aforementioned problems, the present invention provides a backstop structure for fishing reels, solving the issues of complex structure and numerous components in existing backstop mechanisms. The structure includes a bracket, a ratchet sleeve, and a backstop plate. The ratchet sleeve and the backstop plate are rotatably connected to the bracket. The outer surface of the ratchet sleeve is circumferentially provided with multiple inverted ratchet teeth. The backstop plate has a first protrusion and a second protrusion at its two ends near the ratchet sleeve. Both the first and second protrusions extend towards the ratchet sleeve and are positioned close to each other. The first protrusion engages with the ratchet teeth to limit the forward-rotating ratchet sleeve, while the second protrusion engages with the ratchet teeth to disengage the reverse-rotating ratchet sleeve from the first protrusion.
[0005] Preferably, the ratchet has two working surfaces, a short side and a long side. The outer side of the first protrusion can abut against the short side of the ratchet to achieve a reverse stop when the ratchet sleeve rotates forward. The outer side of the second protrusion can contact the long side of the ratchet to be pushed by the long side of the ratchet when the ratchet sleeve rotates in reverse, thereby driving the reverse stop plate to rotate.
[0006] Preferably, there are 6 to 12 ratchet teeth, which are evenly distributed on the outer periphery of the ratchet sleeve.
[0007] Preferably, the free end edges of both the first and second protrusions are rounded.
[0008] Preferably, the bracket is provided with a backstop plate hole, and a backstop plate column that is clearance-fitted with the backstop plate hole is provided in the backstop plate hole, and the backstop plate and the backstop plate column are riveted together.
[0009] Preferably, the bracket is provided with a ratchet sleeve hole, one end of the ratchet sleeve is installed in the ratchet sleeve hole, and the other end is in frictional engagement with the planar gear; the planar gear is fixedly connected to the handle, and when the handle is rotated, the ratchet sleeve is driven to rotate synchronously through the planar gear.
[0010] Preferably, the ratchet sleeve and ratchet teeth are integrally formed, and both are made of die-cast zinc.
[0011] The beneficial effects of this utility model are as follows: the first and second protrusions respectively engage with the ratchet, which, compared to the traditional anti-reverse plate that achieves limiting and disengagement through a single structure, avoids jamming during the forward and reverse switching process of the ratchet sleeve, making the fishing reel's line winding and unwinding operation smoother; the two protrusions distribute the contact force, reducing wear on the anti-reverse plate and extending its service life. Stable anti-reverse function can be achieved solely through the cooperation of the ratchet sleeve and the anti-reverse plate, reducing the number of parts, simplifying the overall structural design, shortening the assembly process, lowering production and manufacturing costs, and facilitating widespread application.

In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0018] The following describes a backstop structure for a fishing reel provided in an embodiment of this application.
[0019] Please see Figures 1 to 4 The fishing reel uses a backstop structure, including a bracket 1, a ratchet sleeve 2, and a backstop plate 3. The ratchet sleeve 2 and the backstop plate 3 are rotatably connected to the bracket 1. The outer surface of the ratchet sleeve 2 has multiple inverted ratchet teeth 201 circumferentially arranged, all extending towards the backstop plate 3, forming an inverted structure tilted towards one side of the backstop plate 3. The two ends of the backstop plate 3 near the ratchet sleeve 2 are respectively provided with a first protrusion 301 and a second protrusion 302. Both the first protrusion 301 and the second protrusion 302 extend towards the ratchet sleeve 2 and are arranged close to each other, allowing the first protrusion 301 and the second protrusion 302 to respectively engage with different working surfaces of the inverted ratchet teeth 201. The first protrusion 301 engages with the ratchet teeth 201 to limit the forward rotation of the ratchet sleeve 2, and the second protrusion 302 engages with the ratchet teeth 201 to disengage the reverse rotation of the ratchet sleeve 2 from the first protrusion 301. Throughout the process, the first protrusion 301 and the second protrusion 302 engage with the ratchet 201 respectively. Compared to the traditional backstop plate 3, which uses a single structure to achieve limiting and disengagement, this division of labor avoids jamming during the forward and reverse switching process of the ratchet sleeve 2, making the line reel operation smoother. The two protrusions distribute the contact force, reducing wear on the backstop plate 3 and extending its service life. Stable backstop function can be achieved solely through the cooperation of the ratchet sleeve 2 and the backstop plate 3, reducing the number of parts, simplifying the overall structural design, shortening the assembly process, reducing production and manufacturing costs, and facilitating widespread application.
[0020] Furthermore, the ratchet 201 has two working surfaces, a short side and a long side. The outer side of the first protrusion 301 can abut against the short side of the ratchet 201 to achieve a reverse stop when the ratchet sleeve 2 rotates forward. The outer side of the second protrusion 302 can contact the long side of the ratchet 201 to be pushed by the long side of the ratchet 201 when the ratchet sleeve 2 rotates backward, driving the reverse stop plate 3 to rotate. Specifically, the short side of the ratchet 201 refers to the shorter working surface of the ratchet 201, which abuts against the outer side of the first protrusion 301 when the ratchet sleeve 2 rotates forward. The angle between the two restricts the ratchet sleeve 2 from continuing to rotate forward, so that the reverse stop plate 3 can achieve a reverse stop function for the ratchet sleeve 2. It can stably withstand the force generated by the fishing line due to the fish's pulling force, and the reverse stop plate 3 can stop the ratchet sleeve 2 in time to prevent the fishing line from slack due to the ratchet sleeve 2 rotating backward. The long side of the ratchet 201 refers to the longer working surface of the ratchet 201, which is used to engage with the outer side of the second protrusion 302 when the ratchet sleeve 2 reverses, providing a smooth pushing surface. This pushes the second protrusion 302 to drive the anti-reverse plate 3 to rotate around the anti-reverse plate column 4, causing the first protrusion 301 to disengage from the short side of the ratchet 201, releasing the anti-reverse limit, without affecting the line release efficiency, meeting the need for flexible line release and retrieval during fishing, and is easy to use.
[0021] In this embodiment, specifically, the ratchet sleeve 2 includes a cylindrical section and a ratchet section. The cylindrical section is the body part of the ratchet sleeve 2 without ratchet teeth, and the ratchet section is the part of the ratchet sleeve 2 with ratchet teeth in the circumferential direction. The tooth tip circle diameter of the ratchet section is 15~30mm, and the outer diameter of the cylindrical section is 10~20mm. The tooth tip width of the ratchet 201 is 0.7~2.5mm, and the tooth tip included angle of the ratchet 201 is 20°~40°.
[0022] Specifically, there are 6 to 12 ratchet teeth 201, evenly distributed on the outer periphery of the ratchet sleeve 2. In this embodiment, there are 6 ratchet teeth 201. The number of ratchet teeth 201 needs to be set according to the specifications of the fishing reel and the required backstop response speed, and it matches the spacing between the first protrusion 301 and the second protrusion 302 of the backstop plate 3 to ensure that during the rotation of the ratchet sleeve 2, there is always one inverted ratchet tooth 201 that can engage with the first protrusion 301 or the second protrusion 302. The evenly distributed spacing of the ratchet teeth 201 makes the force on the ratchet sleeve 2 more balanced during rotation and reduces local wear of the ratchet teeth 201.
[0023] Furthermore, the free end edges of the first protrusion 301 and the second protrusion 302 are rounded to avoid jamming when in contact with the ratchet 201, making the ratchet sleeve 2 disengage more smoothly and reducing local wear of the first protrusion 301, the second protrusion 302 and the ratchet 201, thus extending their service life.
[0024] Specifically, the bracket 1 is provided with a backstop plate hole, and a backstop plate column 4 with clearance fit is provided in the backstop plate hole. The backstop plate 3 and the backstop plate column 4 are riveted together. The backstop plate 3 and the backstop plate column 4 are riveted together on a press using a special jig to form a backstop plate assembly. The backstop plate assembly is then installed into the backstop plate hole of the bracket 1. Through the clearance fit between the backstop plate hole and the backstop plate column 4, the backstop plate 3 is rotatably connected to the bracket 1.
[0025] Specifically, the bracket 1 has a ratchet sleeve hole, one end of the ratchet sleeve 2 is installed into the ratchet sleeve hole, and the other end is in frictional engagement with the planar gear 5; the planar gear 5 is fixedly connected to the handle, and when the handle is rotated, the ratchet sleeve 2 is driven to rotate synchronously through the planar gear 5. In actual use, since the planar gear 5 drives the ratchet sleeve 2 to rotate synchronously through friction, in order to reduce noise and ensure good friction performance, the angler can add an appropriate amount of lubricating oil between the friction surface of the ratchet sleeve 2 and the friction surface of the planar gear 5.
[0026] Specifically, the ratchet sleeve 2 and the ratchet tooth 201 are integrally formed, and both are made of die-cast zinc. The integral forming process reduces the number of parts, simplifies the manufacturing process, lowers production costs, helps improve production efficiency, and shortens the production cycle; without the need for additional connecting parts or tools, it can save assembly time and improve assembly efficiency.
[0027] In this embodiment, the backstop plate 3 is made of stainless steel or carburized 08F steel plate. Stainless steel or carburized 08F steel plate can improve the wear resistance of the product and reduce the risk of backstop function failure.
[0028] The working process of this utility model is as follows: When the angler turns the handle to reel in the line, the handle drives the planar gear 5 to rotate synchronously. The planar gear 5, through friction, drives the ratchet sleeve 2 to rotate clockwise. The first protrusion 301 abuts against the short side of the ratchet 201, firmly locking the ratchet sleeve 2 and achieving the anti-reverse function, ensuring that the fishing line is always taut during the reeling process. When the user needs to release the line and play the fish, turning the handle drives the planar gear 5 and the ratchet sleeve 2 to rotate counterclockwise. The second protrusion 302, pushed by the long side of one of the ratchet 201, will drive the anti-reverse plate 3 to rotate around the anti-reverse plate post 4, causing the first protrusion 301, which was originally abutting against the short side of the other ratchet 201, to disengage, releasing the restriction on the ratchet sleeve 2 and realizing the smooth release of the fishing line.
[0029] In this invention, the first protrusion 301 and the second protrusion 302 respectively engage with the ratchet 201. Compared to the traditional anti-reverse plate 3, which uses a single structure to achieve limiting and disengagement, this division of labor avoids jamming during the forward and reverse switching process of the ratchet sleeve 2, making the fishing reel's line winding and unwinding operation smoother. The two protrusions distribute the contact force, reducing wear on the anti-reverse plate 3 and extending its service life. Stable anti-reverse function can be achieved solely through the engagement of the ratchet sleeve 2 and the anti-reverse plate 3, reducing the number of parts, simplifying the overall structural design, shortening the assembly process, lowering production and manufacturing costs, and facilitating widespread application.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
