Description

Technical Field

[0001] This utility model belongs to the technical field of fishing tackle, specifically a stepless adjustable spiral brake structure. Background Technology

[0002] A fishing reel is a device used to wind fishing line during fishing. It plays a crucial role in fishing activities. The spool is one of the core components of the fishing reel. Its size, material, and shape directly affect the performance of the fishing reel. The size of the spool determines the capacity of the fishing line. Generally speaking, the larger the spool, the more fishing line it can hold. The main function of the braking system is to control the rotation speed of the spool and prevent the fishing line from coming out too quickly during casting or when the fish is struggling, which would cause the line to break. Magnetic brakes use a magnetic field to generate resistance on the spool.

[0003] The infinitely adjustable spiral brake structure on fishing reels is a relatively advanced and practical braking design. It can precisely adjust the braking force according to the angler's needs. Whether it is a small braking force required when casting light baits or a large braking force required to brake the spool when casting large baits, it can effectively reduce the probability of line breakage, improve casting accuracy and the success rate of playing fish. It can adapt to various fishing environments and fish species. For example, in fast-flowing waters or when fishing for large fish, the braking force can be increased; while in calm waters or when fishing for small fish, the braking force can be appropriately reduced, making the fishing reel more flexible and versatile in handling.

[0004] In the existing technology, the continuously variable adjustable spiral brake has a complex structure, consumes a lot of materials, is not conducive to cost saving, and is difficult to set more brake gears, and cannot avoid other parts.

[0005] Therefore, a continuously adjustable spiral brake structure is proposed to address the above problems. Summary of the Invention

[0006] To address the problems mentioned in the background art, this utility model provides a stepless adjustable spiral brake structure, which has the advantages of not interfering with other components inside the housing, stepless adjustment, and the ability to freely add or subtract magnets on the magnet base to adjust for more brake gears.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a stepless adjustable spiral brake structure, including a spool, a corresponding magnet seat on one side of the spool, magnets evenly distributed on the magnet seat, a limiting component between the magnets and the magnet seat, a lifting sleeve fixedly connected to the side of the magnet seat away from the spool, a spiral sleeve fitted on the lifting sleeve, a protrusion fixedly located on the outer side of the lifting sleeve away from the magnet seat, a spiral groove opened on the spiral sleeve at a position matching the protrusion, the protrusion being located within the spiral groove, a lifting limiting sleeve fitted on the outer side of the spiral sleeve, a deck connected to the lifting limiting sleeve, a housing connected to the deck, a knob installed on the housing, a knob linkage rod fixedly located on the knob, a spiral sleeve linkage rod fixedly located near the edge of the spiral sleeve near the deck, and the spiral sleeve linkage rod connecting to the knob linkage rod.

[0008] Preferably, the magnet holder has a mounting groove at a position corresponding to the magnet, and the magnet is placed in the mounting groove.

[0010] Preferably, a limiting groove is formed on the inner wall of the lifting limiting sleeve at the position corresponding to the protrusion, and the end of the protrusion extends into the limiting groove.

[0011] Preferably, a deck ring is fixedly connected to the side of the deck away from the shell, and the lifting limit sleeve is located inside the deck ring.

[0012] Preferably, a first arc-shaped limiting groove is provided on the deck at the position corresponding to the spiral sleeve linkage rod, and a second arc-shaped limiting groove is provided on the housing at the position corresponding to the knob linkage rod.

[0013] Preferably, an insertion groove is provided on the end face of the spiral sleeve linkage rod away from the spiral sleeve, and the end of the knob linkage rod away from the knob extends into the insertion groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model controls the magnet to extend into the spool by the cooperation of the spiral groove and the protrusion.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1 to 5As shown, this utility model provides a stepless adjustable spiral brake structure, including a spool 1, a corresponding magnet seat 2 on one side of the spool 1, magnets 3 evenly distributed on the magnet seat 2, a limiting component 4 between the magnets 3 and the magnet seat 2, a lifting sleeve 5 fixedly connected to the side of the magnet seat 2 away from the spool 1, a spiral sleeve 6 fitted on the lifting sleeve 5, a protrusion 7 fixedly fixed on the outer side of the lifting sleeve 5 away from the magnet seat 2, a spiral groove 8 opened on the spiral sleeve 6 at a position matching the protrusion 7, the protrusion 7 being located within the spiral groove 8, a lifting limiting sleeve 9 fitted on the outer side of the spiral sleeve 6, a deck 10 connected to the lifting limiting sleeve 9, a housing 11 connected to the deck 10, a knob 12 installed on the housing 11, a knob linkage rod 13 fixedly fixed on the knob 12, a spiral sleeve linkage rod 14 fixedly fixed on the side of the spiral sleeve 6 near the edge of the deck 10, and the spiral sleeve linkage rod 14 connected to the knob linkage rod 13.

[0031] Specifically, a mounting groove 15 is provided on the magnet base 2 at the position corresponding to the magnet 3, and the magnet 3 is placed in the mounting groove 15 for easy placement of the magnet 3.

[0032] Furthermore, the limiting component 4 includes a groove 401 formed on the inner wall of the mounting slot 15. A movable plate 402 is provided in the groove 401. A limiting post 403 is fixedly connected to the side of the movable plate 402 near the magnet 3. A limiting groove 404 is formed on the magnet 3 at the position corresponding to the limiting post 403. The limiting post 403 extends into the limiting groove 404. A spring 405 is connected to the side of the movable plate 402 away from the limiting post 403. A movable rod 406 is provided inside the spring 405. One end of the movable rod 406 is fixedly connected to the movable plate 402, and the other end passes through the magnet seat 2 and is connected to a pulling block 407. This allows for quick assembly and disassembly of the magnet 3, so that the number of magnets 3 can be freely increased or decreased, and more braking positions can be formed by adjustment.

[0033] Furthermore, a limiting groove 901 is provided on the inner wall of the lifting limit sleeve 9 at the position corresponding to the protrusion 7. The end of the protrusion 7 extends into the limiting groove 901 to restrict the rotation of the protrusion 7, so that the lifting sleeve 5 drives the magnet seat 2 to move.

[0034] It is worth noting that a deck ring 16 is fixedly connected to the side of the deck 10 away from the shell 11, and the lifting limit sleeve 9 is located inside the deck ring 16.

[0035] It is worth noting that a first arc-shaped limiting groove 1001 is provided on the deck 10 at the position corresponding to the spiral sleeve linkage rod 14, and a second arc-shaped limiting groove 1101 is provided on the housing 11 at the position corresponding to the knob linkage rod 13.

[0036] It is worth mentioning that the end face of the spiral sleeve linkage rod 14 away from the spiral sleeve 6 is provided with an insertion groove, and the end of the knob linkage rod 13 away from the knob 12 extends into the insertion groove, so that the spiral sleeve linkage rod 14 can be connected to the knob linkage rod 13, so that the knob 12 can drive the spiral sleeve 6 to rotate.

[0037] Working principle and process: Rotating knob 12, in turn, rotates knob linkage rod 13, which in turn drives spiral sleeve linkage rod 14. Spiral sleeve linkage rod 14 drives spiral sleeve 6 to rotate. The first arc-shaped limiting groove 1001 and the second arc-shaped limiting groove 1101 on the deck 10 and the shell 11 can limit the rotation angle. When spiral sleeve 6 rotates, the protrusion 7 on lifting sleeve 5 corresponds to the spiral groove 8 on spiral sleeve 6 and can only move through lifting limit sleeve 9. Lifting sleeve 5 and magnet seat 2 combine to push magnet seat 2 into spool 1, that is, push magnet 3 into spool 1. Inside the spool 1, when the spool 1 rotates, the magnetic field exerts a force on the metal spool 1 (or other metal parts) to create resistance, thus achieving a braking effect. When it is necessary to add or remove magnets 3, pull the pull block 407 of the limiting component 4, and then the movable rod 406 drives the movable plate 402 to move. Then the limiting post 403 disengages from the limiting groove 404 on the magnet 3, and the magnet 3 can be removed. Magnets 3 can be freely added or removed on the magnet base 2. Different resistance levels are formed according to the number of magnets 3. With adjustment, more braking gears can be formed.
