The present invention relates to a spool cover assembly for a spool backlash prevention device of a fishing bait reel, which has improved productivity, excellent workability, low manufacturing cost, and very low incidence of failure compared to the conventional device. Permanent magnets are used to prevent backlash.

When casting, the extra flying speed, including the bait, and the speed of the fishing line being released from the spool do not match, the excessive fishing line from the spool gets stuck in the spool. As a means to prevent this, a centrifugal brake that controls the rotational speed of the spool is used. However, the conventional centrifugal brake has a disadvantage in that it is difficult to finely adjust the braking force and wear of the brake shoe and the braking ring occurs. there was. As such, the spool cover assembly for the backlash prevention device, which is intended to brake with the magnet plate 1b by using the permanent magnet 10, has been conceived, but the upper and lower parts of the body penetrate due to the difficulty of injection technology.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figs. 3 and 4, the assembly of the spool cover 60 of the present invention is assembled on the inside of the side cover 2, and on the right side of the drawing, the fixing cam 3 and the fixing cam assembled to the boss of the spool shaft 1a. The magnet plate 1b fixed to the moving cam 4 assembled by the inclination clutch type to 3 is assembled. The magnet plate 1b is a non-magnetic conductor and is located at a distance from the permanent magnet 10 assembled to the spool cover 20. At the initial rotation of the spool 1, the moving cam 4 is fixed by inertial force. The rotation of the spool 1 enters the high speed and is separated from the fixed cam 3 while approaching the permanent magnet 10 while being rotated without being separated from the cam 3. As a result, a brake action caused by a magnetic field is generated between the magnet plate 1b and the permanent magnet 10, and the rotation of the spool 1 is reduced while the strength of the brake action is slightly reduced, resulting in the backlash of the spool 1. To prevent it.

The structure and operation of the present invention will be described.

The spool cover 60 of the present invention is made of a tubular body 61 as shown in the drawing, and is inserted into the hole 74 of the rotation cam 70 so as to be seated therein, but the groove 44 into which the bearing 44 is inserted. ) Is formed in the center of the bottom surface. And the side of the arc to form the arc-shaped permanent magnet holder 20 is inserted into the groove 67 is formed in the gap and the projection 21a of the permanent magnet holder 20 can be exposed on the side An arcuate projecting end 64 having a 64a is formed integrally with the body 61. The outer surface of the body 61 is then provided with two or more protrusions 62 for mounting on the inner frame inside the side cover 2 and holes 69 for mounting on the side cover 2 with screws. The formed fixed end 68 is formed, and the holes 63 through which the screw 50 for firmly fixing the side cover 2 are formed. This state can be seen through FIGS. 3 and 4.

Next, the rotary cam 70 has a hole 74 through which the insertion end 65 formed in the bottom surface of the spool cover 60 can be inserted into the center, and a spiral blade 72 is formed on the outer surface thereof. One leg 73 is formed to rotate by being caught by the protrusion 82 of the dial 80. Subsequently, the dial 80 is mounted on the inner end of the side cover 2 to stabilize the rotation, and a protrusion 81 is formed to control the rotation distance, and the spool cover 60 is formed in the central hole 83. The end of the insertion end 65 of is inserted. And the leg 73 of the rotary cam 70 is caught and rotated by the inner projection 82.

Next, the permanent magnet holder 20 is inserted into the arc-shaped groove 67 of the spool cover 60, the upper surface is formed with holes 25 into which the permanent magnets 10 are inserted and the space portion of the bottom surface. In the 23, protrusions 24 are formed to allow the support plate 30 and the spring 40 to be fitted therein. Subsequently, between the gaps 64a facing inward of the spool cover 60, the grooves 22 are exposed while the protrusions 21a of the permanent magnet holder 20 are fitted and the spiral blades 72 of the rotary cam 70 are inserted. ) Is formed so that the arc-shaped body 21 of the permanent magnet holder 20 is raised or lowered as the rotary cam 70 rotates. Of course, the hole 25 is inserted into the disk-shaped permanent magnets 10, in the present invention can be used five permanent magnets 10 of about 5mm in diameter. For reference, the conventional spool cover assembly has the above-described structural constraints that only three permanent magnets having a diameter of about 5 mm can be used.

The permanent magnets 10 inserted into the space 23 of the permanent magnet holder 20 are securely supported by the support plate 30 fixed while being fitted to the protrusions 24 formed in the space 23. Spring 40 for supporting the support plate 30 to rise between the outer circumference of the protrusion 24 of the permanent magnet holder 20 and the bottom of the support plate 30 and the bottom of the groove 67 of the spool cover 60. Is inserted. On the other hand, between the bearing 44 and the bottom of the groove 66 of the spool cover 60, a disk-shaped support plate 46 may be added to prevent the axial movement of the spool shaft 1a as shown in the drawing. Instead of the spring 40, an elastic rubber or citron type leaf spring may be used.

The present invention as described above is assembled and used as shown in Figures 3 and 4, Figure 3 rotates the dial 80 to the right, the rotary cam 70 is rotated to the right and the permanent magnet holder by the movement of its spiral blade 72 20 is the state closest to the dial 80. Therefore, the distance between the permanent magnets 10 and the magnet plate 1b is the farthest state, and casting the reel in this state, the magnetizing action is relatively weak. In this state, when the rotary cam 70 is rotated left by rotating the dial 80 left, the entire permanent magnet holder 20 is connected to the helical blade 72 of the rotary cam 70 that rotates in the groove 22 of the protrusion 21a. As a result of being raised in the arc-shaped groove 67 formed in the body 61 of the spool cover 60, the spring 40 acts a resilient force to help the synergistic action. This state is as shown in Fig. 4, the distance between the magnet plate 1b and the permanent magnets 10 protruding by the rotation of the spool 1 is the shortest and the magnetizing brake action force is maximized. Of course, if the dial 80 is turned a little left, the entire permanent magnet holder 20 moves slightly toward the dial 80 again, so that the distance between the permanent magnets 10 and the magnet plate 1b is free and fine. It is adjustable.

In the above, the spool cover 60 is formed integrally with the body 61 is a protruding end 64 having an arc-shaped groove 67 into which the entire permanent magnet holder 20 can be inserted as shown in the drawing. It can be seen that only the upper portion is open, thereby allowing the entire assembly of the two-sided magnet holder 20 can be simply assembled from the upper side, and as the conventional body 61 of the spool cover 60 is not configured to penetrate vertically. Due to the five permanent magnets 10 can be used as described above, the backlash preventing action can be maximized, and even if the distance between the permanent magnets 10 and the magnet plate 1b is somewhat separated, Compared to a device that uses a permanent magnet of the number will be excellent. And the spiral blade 72 of the rotary cam 70 is capable of raising and lowering the entire permanent magnet holder 20 smoothly and finely, unlike the conventional lever-operated device.

The present invention as described above, by making the body 61 of the spool cover integrally rather than vertically penetrating to reduce the unnecessary space, a large number of permanent magnets can be used, the magnetizing brake effect is excellent, the spool cover Parts such as a permanent magnet holder can be easily assembled through the upper part, so that the productivity is improved, the workability is excellent, the manufacturing cost is low, and the incidence of failure is very low compared to the conventional device.

Therefore, the rotation of the spool can be guided more ideally than before, and the brake action can be finely adjusted to improve the reduction of flying distance, and the durability of the parts related to the backlash prevention device can be greatly increased. have.
