Description

Technical Field

[0001] The utility model relates to the technical field of fishing reels, in particular to a magnetic brake mechanism for a fishing reel. Background Art

[0002] In order to prevent the fishing reel from releasing the line too quickly when casting the rod, the fishing reel needs to be equipped with a brake mechanism to slow down the fishing reel. The magnetic brake mechanism is widely used due to its high stability.

[0003] In order to enhance the self-adjusting ability of the braking force of the fishing reel during the casting process, the existing magnetic brake mechanism generally adopts the method of adding a centrifugal component. For example, the patent with publication number CN210695589U discloses a suspended magnetic brake mechanism for a fishing reel, including a cylindrical magnetic seat installed under the side cover of the fishing reel, and a suspended brake assembly (i.e., a centrifugal assembly) is provided on the circumference of the outer wall of the inner end of the cylindrical magnetic seat. The suspended brake assembly consists of an arc-shaped suspension rod with multiple magnetic sheets embedded on the outside, a spring and an annular baffle. A connecting protrusion and a clamping protrusion are respectively formed on the circumference of the outer wall of the cylindrical magnetic seat. One end of the arc-shaped suspension rod is hinged to the connecting protrusion through a hinge column, and the other end of the arc-shaped suspension rod extends into the clamping protrusion and is pressed against the inner wall of the clamping protrusion through a spring. The annular cover plate is fixed to the end surface of the inner end of the cylindrical magnetic seat and is hinged to the hinge column on the arc-shaped suspension rod.

[0004] When assembling the above-mentioned suspended brake assembly, it is necessary to first place the hinge column at one end of the arc-shaped suspension rod in the connecting protrusion, and press the other end together with the spring into the snap protrusion, and then fix the hinge column of the arc-shaped suspension rod by installing the annular baffle. The installation process is relatively complicated, and since a magnet is embedded in the outer side of the arc-shaped suspension rod, its center of gravity is biased outward. At the same time, under the elastic force of the spring, the arc-shaped suspension rod is easily separated from the connecting protrusion and the snap protrusion, which makes it difficult to complete the docking of the annular baffle in one go, causing inconvenience in installation and affecting assembly efficiency. Utility Model Content

[0005] In order to solve the above-mentioned deficiencies in the prior art, the utility model provides a magnetic brake mechanism for a fishing reel.

[0006] The cam is secured to the outer wall of the fishing reel with a spring, and the cam has a hook portion for securing the fishing reel with a hook portion for urging the fishing reel to move relative to the cam. After the spring is placed in the spring mounting hole of the arc-shaped mounting plate, the clamping seat of the arc-shaped mounting plate is assembled with the outer hook of the support plate. At this time, the arc-shaped mounting plate is stabilized on the connecting seat under the cooperation of the support plate and the clamping seat. The arc-shaped mounting plate is fixed by the hinge to complete the assembly of the centrifugal assembly, which reduces the installation process, improves the stability of the arc-shaped mounting plate during installation, and thus ensures assembly efficiency.

[0007] There are two centrifugal components, which are centrally symmetrically arranged on the circumference of the outer wall of the magnetic base.

[0008] The distal end of the arc-shaped mounting plate is formed with an inward protrusion on one side facing the magnetic base. In the initial state of the spring, the inward protrusion contacts the outer wall of the magnetic base. The design of the inward protrusion ensures that the centrifugal assembly has a certain stability in the initial state of the spring.

[0009] The hinged member is a hinge bolt, the upper end of which is fixed with a sleeve rotatably connected to the hinge hole. The rotational cooperation between the hinge hole and the sleeve can reduce the friction when the arc-shaped mounting plate rotates away from the outer wall of the magnetic base, thereby improving the braking force during self-adjustment.

[0010] The lifting transmission assembly includes a lifting knob and a reel cover. The reel cover is fixedly mounted below the end cover, and a receiving cavity is formed on the side of the reel cover away from the end cover. A lifting cylinder is formed in the middle of the receiving cavity, and a positioning plate is formed on the inner wall of the receiving cavity. A rotating column formed at the bottom of the lifting knob passes through the end cover and the reel cover in sequence and is rotatably connected to the positioning plate. A spiral groove is formed on the outer wall of the rotating column that passes through the reel cover. The magnetic base is sleeved on the lifting cylinder through the middle through hole, and a slider that matches the spiral groove is formed on the outer wall of the magnetic base. The end cover, reel cover, and magnetic base are integrally installed via the rotating column of the lifting knob. Compared with the multi-bolt triangular fixing method in the prior art, this method simplifies the installation steps and improves installation efficiency.

[0011] A guide plate is formed on the outer wall of the magnetic base near the slider. The outer side of the guide plate has a guide surface that slides with the outer edge of the positioning plate. The sliding fit between the guide plate and the positioning plate can further ensure the stability of the magnetic base during the lifting process.

[0012] The guide plate extends upward and is integrally formed with a limiting plate of one of the centrifugal assemblies.

[0013] A positioning column is formed in the middle of the inner side of the end cover, and a positioning groove matching the positioning column is opened on the side of the winding drum cover close to the end cover. A connecting bolt for threading through the winding drum cover and the positioning column is provided in the lifting cylinder.

[0014] A connecting hole is provided on the positioning plate, a rotating shaft portion matching the connecting hole is formed on the end of the rotating column, and a knob bolt is threadedly connected to the rotating column, and the head of the knob bolt contacts the surface of the positioning plate.

[0015] A sound-generating component is provided on the lifting knob, and the sound-generating component includes a sound-generating spring and a sound-generating pin. A pin groove is provided on the inner side of the lifting knob, and the sound-generating spring is located in the pin groove. One end of the sound-generating pin is inserted into the sound-generating spring, and the other end of the sound-generating pin is formed with a hemispherical pin head that abuts against the sound-generating spring. A knob mounting groove corresponding to the position of the lifting knob is provided on the outer side of the end cover, and a plurality of sound-generating grooves that cooperate with the hemispherical pin head are arranged circumferentially on the groove surface of the knob mounting groove.

[0016] The beneficial effects of the present invention are as follows: this solution stabilizes the arc-shaped mounting plate on the connecting seat by cooperating with the outer hook of the support plate on the outer wall of the magnetic seat, thereby improving the stability of the arc-shaped mounting plate during installation. Compared with the prior art, the annular baffle is eliminated, and the fixation of the arc-shaped mounting plate can be achieved only by hinged bolts, which reduces the assembly process of the centrifugal component and thus ensures assembly efficiency.

[0022] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the present invention are clearly and completely described below in conjunction with the accompanying drawings. Other embodiments obtained by those skilled in the art without making any creative work should fall within the scope of protection of the present invention.

[0023] like Figure 1 and Figure 2As shown, the utility model provides a magnetic brake mechanism for a fishing reel, which is provided with a magnetic base 2. The magnetic base 2 is connected to the end cover 1 of the fishing reel via a lifting transmission component. A centrifugal component is provided on the circumference of the outer wall of the magnetic base 2. In this embodiment, there are two centrifugal components, which are centrally symmetrically arranged on the circumference of the outer wall of the magnetic base 2. Each centrifugal component includes an arc-shaped mounting plate 3 with multiple magnetic sheets 4 embedded on the outer side, a spring 7 and a hinge. A connecting seat 201 and a support plate 202 are formed on the outer wall of the magnetic base 2. The arc-shaped mounting plate 3 is water-proof. It is placed flat on the connecting seat 201 and the support plate 202, and a hinge hole 304 is provided at the proximal end of the arc-shaped mounting plate 3. In this embodiment, the hinged member is a hinge bolt 5, which passes through the hinge hole 304 and is threadedly connected to the connecting seat 201. A spring mounting hole 302 is provided at the end of the arc-shaped mounting plate 3 near the hinge hole 304. One end of the spring 7 is located in the spring mounting hole 302, and the other end of the spring 7 is against the limit plate 203 on the formed magnetic seat 2. The support plate 202 is along the outer wall of the magnetic seat 2. The outer hook portion 2021 is bent to form a curved mounting plate 3, and a card seat 301 is formed at the bottom of the curved mounting plate 3. A card interface 3011 for inserting the outer hook portion 2021 is provided on the outside of the card seat 301, and there is a movable gap between the inner side of the card interface 3011 and the outer hook portion 2021. Specifically, in this embodiment, the outer hook portion 2021 is set toward the side of the connecting seat 201, and the card interface 3011 is opened toward the side of the magnetic base 2 and toward the side of the outer hook portion 2021, so that the outer hook portion 2021 can be inserted from the outside of the card interface 3011. When installing the centrifugal assembly, the spring 7 is placed in the spring mounting hole 302 of the arc-shaped mounting plate 3, and the arc-shaped mounting plate 3 is stabilized on the connecting seat 201 by cooperating with the clamping seat 301 of the arc-shaped mounting plate 3 and the outer hook 2021 of the support plate 202 of the magnetic seat 2, thereby improving the stability of the arc-shaped mounting plate 3 during installation. Compared with the prior art, the annular baffle is eliminated, and the arc-shaped mounting plate 3 is directly fixed on the magnetic seat 2 by the hinge bolt 5, which reduces the assembly process and ensures the assembly efficiency.

[0024] In order to ensure that the arc-shaped mounting plate 3 has a certain stability in the initial state of the spring 7, an inward protrusion 303 is formed on the side of the distal end of the arc-shaped mounting plate 3 facing the magnetic base 2. In the initial state of the spring 7, the inward protrusion 303 contacts the outer wall of the magnetic base 2.

[0025] In order to reduce the friction when the arc-shaped mounting plate 3 rotates away from the outer wall of the magnetic base 2, so that it can quickly approach or move away from the spool in a centrifugal state and improve its braking force during self-adjustment, a sleeve 6 is fixed to the upper end of the hinge bolt 5 and is rotatably connected to the hinge hole 304.

The integrated installation of the end cover 1, the cable reel cover 8 and the magnetic base 2 is completed only by relying on the connecting bolts 10 and the rotating column 901 of the lifting knob 9. Compared with the existing technology in which multiple bolts are required to fix the end cover 1 and the cable reel cover 8, and the cable reel cover 8 and the magnetic base 2, this connection method simplifies the installation steps and improves the installation efficiency.

[0027] In order to further ensure the stability of the magnetic base 2 during the lifting process, a guide plate 206 is formed on the outer wall of the magnetic base 2 close to the slider 205. The outer side of the guide plate 206 has a guide surface that slides with the outer edge surface of the positioning plate 802. Preferably, the guide plate 206 extends upward and is integrally formed with the limit plate 203 of one of the centrifugal components.

[0028] In order to pre-position the end cover 1 before connecting it to the cable reel cover 8, a positioning column 101 is formed in the middle of the inner side of the end cover 1, and an internal thread groove is provided on the positioning column 101 to cooperate with the connecting bolt 10. A positioning groove 803 is provided on the side of the cable reel cover 8 close to the end cover 1 to cooperate with the positioning column 101.

[0029] In this embodiment, a connecting hole is provided on the positioning plate 802, and a rotating shaft portion 9012 is formed at the end of the rotating column 901 to match the connecting hole, and a knob bolt 11 is threadedly connected to the rotating column 901, and the head of the knob bolt 11 contacts the surface of the positioning plate 802.

[0030] In order to know the position of the magnetic seat 2 during the lifting process, a sound component is provided on the lifting knob 9, and the sound component includes a sound spring 13 and a sound pin 12. A pin groove 902 is provided on the inner side of the lifting knob 9. The sound spring 13 is located in the pin groove 902.

Figure 4As shown, the outer side of the end cover 1 is provided with a knob mounting groove 102 corresponding to the position of the lifting knob 9, and the groove surface of the knob mounting groove 102 is circumferentially arranged with a plurality of sounding grooves 103 that cooperate with the hemispherical pin head. Further preferably, an annular embedding groove is provided on the rotating column 901 located on the inner side of the end cover 1, and a rubber pad 14 with a size larger than the through hole of the end cover 1 is installed in the annular embedding groove to ensure that the lifting knob 9 is in close contact with the inner side of the end cover 1 through the rubber pad 14 during the rotation process.

[0031] When implementing this technical solution, the arc-shaped mounting plate 3 with the magnetic sheet 4 embedded and the spring 7 inserted into the spring mounting hole 302 is matched with the outer hook 2021 of the support plate 202 through the clamping seat 301. At this time, the arc-shaped mounting plate 3 is stabilized on the support plate 202 and the connecting seat 201, and one end of the spring 7 is in contact with the limit plate 203.

The magnetic seat 2 is sleeved on the lifting cylinder 801 through the through hole 204, and the magnetic seat 2 is rotated so that the outer side of the guide plate 206 is matched with the positioning plate 802. On the outer edge surface, the rotating column 901 of the lifting knob 9 passes through the end cover 1 and is placed above the winding reel cover 8 together with the end cover 1. Turn the lifting knob 9, and after the slider 205 on the magnetic base 2 is matched with the spiral groove 9011 on the rotating column 901, the positioning column 101 in the middle of the end cover 1 is matched and clamped into the positioning groove 803 on the outside of the winding reel cover 8. The connection between the winding reel cover 8 and the end cover 1, and between the rotating column 901 and the positioning plate 802 are completed by the connecting bolts 10 and the knob bolts 11 respectively, that is, the assembly of the magnetic brake mechanism is completed.
