Abstract
Description
Technical Field
[0001] This utility model relates to the field of teardrop wheel technology, specifically a quick-release teardrop wheel side cover. Background Technology
[0002] A baitcasting reel is a type of fishing reel commonly used in lure fishing. Its features include a spool (line roller) that rotates coaxially with the handle, providing advantages such as precise casting and strong line retrieval, making it suitable for catching medium to large fish.
[0003] An existing patent (authorization announcement number: CN217308841U) discloses a novel water droplet wheel cover switch structure. The key technical points of the solution are as follows: During normal assembly, the end of the switch rod with the switch spring attached is first passed through the hole on the left side of the bracket and out through the through hole. Since the diameter of the switch spring is larger than the diameter of the through hole, the switch spring is engaged inside the through hole. Then, the movable cover is secured to the left end of the main cover by several locking rods. At this time, the other end of the switch rod is inserted into the locking groove by the elastic force of the switch spring, thus locking the movable cover. When opening the movable cover, the switch rod is pulled to the right by the thumb to disengage the switch rod from the locking groove on the movable cover. Then, the movable cover is rotated by hand to disengage it from the switch rod, thus completing the opening of the movable cover. The operation is simple, the switch is convenient, and the aesthetics are high, improving the practicality of the device.
[0004] However, the above technical solution still has certain defects. When disassembling the cover of the water drop wheel, the rotating handle on the side of the water drop wheel cannot be disassembled. Furthermore, the rotating handle is too long, making it inconvenient to carry and assemble. Moreover, it is impossible to adjust the rotation mode of the rotating handle according to one's own habits. Therefore, a quick-release water drop wheel side cover is proposed. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0028] In one embodiment, such as Figures 1-5 As shown, a quick-release teardrop wheel side cover includes a switch assembly 2, a scale ring 3 disposed on the surface of the teardrop wheel, a feed roller 5 rotatably disposed on the scale ring 3, and a locking post 4 rotatably connected to the axis of the feed roller 5. The switch assembly 2 is provided with an opening and closing mechanism 1 on its side, and the scale ring 3 is provided with digital level scales.
[0029] In this embodiment, the line-laying roller 5 is rotatably mounted on the scale ring 3 and is linked with the locking post 4, so that the adjustment of the scale ring 3 directly affects the line-laying resistance. For example, when rotating the scale ring 3, the torque is transmitted through the locking post 4, which can finely adjust the braking force of the line-laying roller 5. The digital scale of the scale ring 3 helps the angler to quickly match different fishing conditions, such as light bait or heavy bait, and improve the casting accuracy.
[0030] In one embodiment, such as Figure 1 and Figure 4As shown, the opening and closing mechanism 1 includes a first rotating handle 11, a second rotating handle 12 threadedly connected to one end of the first rotating handle 11, and a rotating column 14 sleeved on the outside of the first rotating handle 11 and the second rotating handle 12. One end of the rotating column 14 is engaged with the locking plate 13 of the switch assembly 2, and the other end of the rotating column 14 is provided with an extension 15. The opening and closing mechanism 1 is added to the side of the switch assembly 2. By rotating the rotating column 14, the locking column 4 can be driven to unlock, realizing one-handed operation and quick release. When fishing, you only need to turn the rotating column 14 with one hand to quickly open the cover plate 21 without tools or complicated steps. It is suitable for frequent replacement or cleaning of the spool when fishing. Moreover, the mechanical locking is more stable than the spring buckle and can prevent accidental loosening.
[0031] In one embodiment, such as Figure 3 and Figure 5 As shown, the switch assembly 2 consists of a cover plate 21, a threaded ring 22, a base 23, and a locking platform 24. The inner wall of the cover plate 21 has an internal thread that mates with the outer wall of the threaded ring 22. The top of the base 23 is fixedly connected to the threaded ring 22 by welding, and the bottom has a bearing structure that is rotatably connected to the locking platform 24. The inner wall of the base 23 is rotatably connected to the outer wall of the locking platform 24. The inner side of the locking platform 24 is slidably connected to the outer side of the extension 15. The extension 15 is cylindrical, and six sets of squares are provided on the outer wall of the extension 15. The locking platform 24 contains... The side is provided with a groove that mates with the square block of the extension 15; the locking post 4 is rotatably connected to the line-feeding roller 5 to avoid hard friction; the matching design of the extension 15 and the locking platform 24 ensures that the installation position is consistent each time, avoiding repeated brake adjustments; at the same time, the extension 15 and the locking platform 24 are slidably connected to ensure that they can be accurately reset after quick disassembly; the inner wall of the cover plate 21 is provided with internal threads, which form a short-stroke thread engagement with the outer wall of the threaded ring 22; the threaded ring 22 and the base 23 are fixed by welding to prevent the threaded ring 22 from loosening; the thread self-locking + welded base 23 ensures that it will not loosen under the severe vibration during sea fishing or boat fishing.
[0032] As a supplement: Since the outer wall of the extension 15 is provided with 6 sets of blocks, which form a multi-tooth engagement with the groove on the inner side of the locking platform 24, the 6 sets of blocks and the groove cooperate to achieve uniform force distribution in the circumferential direction, avoiding slight movement of the cover plate 21. At the same time, the torque of the fishing line during casting is transmitted to the entire switch assembly 2 through the blocks and the groove, rather than a single buckle.
[0033] In one embodiment, such as Figure 2 and Figure 5As shown, the first rotating handle 11 and the second rotating handle 12 have opposite thread directions, and the bottom of the locking platform 24 is detachably connected to the axial end of the wire feeding roller 5. By having the first rotating handle 11 and the second rotating handle 12 have opposite thread directions, the remaining part can still rotate after disassembling either rotating rod. Moreover, left-handed or right-handed users or users in dark environments do not need to distinguish the direction of rotation, and the forward and reverse torque of the spool during casting can be evenly distributed through the threaded handle.
[0034] In one embodiment, such as Figure 1 As shown, the wire feeding roller 5 is made of metal, which improves its service life and increases its resale value.
[0035] The above embodiment discloses a quick-release baitcasting reel side cover, wherein by setting an opening and closing mechanism 1, the locking column 4 can be unlocked by rotating the rotating column 14, realizing quick release by one hand. At the same time, the inner wall of the cover plate 21 is provided with internal threads, which form a short-stroke thread engagement with the outer wall of the threaded ring 22. The threaded ring 22 and the base 23 are fixed by welding to prevent the threaded ring 22 from loosening. The self-locking of the thread and the welded base 23 ensure that it will not loosen under the severe vibration during sea fishing or boat fishing.
[0036] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
