Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a spinning reel for fishing in which a rear drag type drag adjusting knob is prevented from loosening.

[Prior art]

A drag adjusting mechanism for preventing loosening of a drag adjusting knob of a rear drag type spinning reel for fishing is known from Japanese Utility Model Publication No. 59-127469.

The drag adjusting mechanism of this publication has a female screw formed on the inner circumference of the rear cylindrical portion of the reel unit, and is provided with a leaf spring exposed on the outer side of the rear cylindrical portion to prevent loosening and moderation inside the drag adjusting knob. An uneven strip is provided to engage the leaf spring.

[Problems to be solved by the device]

If the drag adjusting mechanism is configured as described above, the female screw in the rear cylindrical portion of the reel body must be molded at the same time as the reel body or must be machined after the reel body is molded, which increases the manufacturing cost in any case. There are drawbacks.

Since a leaf spring is provided on the outside of the rear cylindrical part and an uneven strip is provided on the drag adjustment knob, seawater, sand, dust, etc. may adhere, or it may enter the knob and prevent loosening prevention and moderation. There is.

There are many drawbacks such as a large number of parts integrally incorporated in the drag adjusting knob, a complicated structure, poor workability, and high cost.

In view of the above-mentioned drawbacks, an object of the present invention is to allow a male screw to be screwed with a female screw of a drag adjusting knob to be easily formed on the outer periphery of the rear cylindrical portion of the reel unit by molding, and to prevent loosening and moderation. Since the locking claws and the ridges and grooves on the inside of the drag adjusting knob are not exposed, the prevention of relaxation due to seawater, sand, dust, etc., and the moderation effect are improved, and the configuration is simple and the work is built-in. The object is to provide a spinning reel for fishing that has good performance and has a reduced number of parts.

[Means for solving problems]

The present invention provides a structure for solving the above-mentioned problems in a fishing spinning reel in which a drag adjusting member arranged on the rear side of a reel body is used to adjust a drag braking member. A male screw is formed on each of the concave-convex strip and the outer periphery of the cylindrical portion, a female screw is formed on the inner periphery of the drag adjusting knob, and a locking claw is fixed to the center of the inner bottom portion of the knob. The gist of the invention is to engage with the above-mentioned uneven line.

〔Example〕

Hereinafter, the present invention will be described with reference to the illustrated embodiment.
From Figure 1 to Figure 3, the spinning reel for fishing is the reel body 1
A rotary shaft cylinder 2 rotatably supported on the rotor shaft 10 is protruded from the front part, a rotor 10 is fixed to the tip end of the rotary shaft cylinder 2, and is driven by a pinion 2a integrally formed at the base end of the rotary shaft cylinder 2. The gear 3 is meshed.

The shaft cylinder 3a of the drive gear 3 is rotatably supported on the reel body 1, and the engaging shaft 4a of the handle 4 is inserted and engaged in the polygonal hole of the shaft cylinder 3a so as to be left-right replaceable.

A spool shaft 5 having a spool 11 attached to its tip is rotatably inserted in the center hole of the rotary shaft cylinder 2 so as to be capable of reciprocating back and forth, and a piece body 12 is fitted to the spool shaft 5 and the spool shaft 5 The retaining ring 13 is fitted into the groove 5a, and the piece 12 is slid integrally with the spool shaft 5.

Further, the terminal end of the spool shaft 12 is slidably and slidably inserted in a hollow cylinder 6 rotatably fitted in the rear portion of the reel body 1 so as to be capable of reciprocating back and forth.

An interlocking gear 14 is fitted in the rotation shaft cylinder 2 in the rotation preventing cylinder 2 on the front side of the pinion 2a of the rotation shaft cylinder 2 in the reel body 1.

A rotating shaft 7 is supported in parallel with the spool shaft 5 in the reel body 1, and a traverse cam groove 7a is formed in the rotating shaft 7.

A small gear 15 is fitted to the tip of the rotary shaft 7 to prevent the small gear 15 from meshing with the interlocking gear 14.

A piece 12 is fitted to the rotary shaft 7, and an unillustrated engaging element provided on the piece 12 is engaged with the traverse cam groove 7a.

A cylindrical portion 1a is formed on the rear portion of the reel body 1, an uneven line 1b is formed on the inner periphery thereof, and a male screw 1c is formed on the outer periphery of the cylindrical portion 1a.

A female screw 8a formed on the inner circumference of the drag adjusting knob 8 is screwed onto the male screw 1c of the cylindrical portion 1a.

A plurality of braking plates 16 and 17 of a drag braking member are alternately arranged together with a friction plate 18 on the outer periphery of the hollow cylinder 6 in the cylindrical portion 1a, and the braking plate 16 is prevented from rotating by the hollow cylinder 6 and the braking plate 17 Is fixed to the inner circumference of the cylindrical portion 1a.

A locking claw 9 is fixed to the center of the inner bottom part of the drag adjusting knob 8, and a hemispherical portion 9a at the tip of the locking claw 9 is engaged with the uneven strip 1b.

The tip of the inner tubular portion 8b of the drag adjusting knob 8 is brought into contact with the braking plate 17, and the spring 19 fitted in the tip concave portion of the tubular portion 8b.
Is brought into contact with the braking plate 17, and the drag braking force is set by the rotation of the drag adjusting knob 8.

When the handle 4 of the fishing spinning reel is rotated, the drive gear 3 is rotated, the rotary shaft cylinder 2 is rotated via the pinion 2a, and the rotor 10 is rotated.

Further, the rotary shaft 7 is interlockedly rotated via the interlocking gear 14 and the small gear 15, so that the bridge 12 and the spool shaft 5 are reciprocated back and forth in the traverse cam groove 7a.

When the fishing line is wound on the spool 11 and a tensile force is applied to the fishing line, the spool shaft 5 is rotated against the drag braking force set by the drag adjusting knob 8.

When the drag adjusting knob 8 is screwed forward, the braking plates 16 and 17 of the drag braking member and the friction plate 18 are tightened to strengthen the drag braking force, and when the drag adjusting knob 8 is screwed back, the drag braking force is weakened.

When the drag adjusting knob 8 is screwed forward and backward, the hemispherical portion 9a at the tip of the locking claw 9 is engaged with the concave-convex strip 1b, so that the moderation action and the loosening prevention action are performed.

When the fishing spinning reel is configured as described above,
Since the male screw 1c can be formed on the outer periphery of the rear cylindrical portion 1a of the reel body 1 by molding, the manufacturing is easy and the manufacturing cost can be reduced.

Since the locking claw 9 is fixed to the inside of the drag adjusting knob 8 and the uneven strip 1b is formed in the rear cylindrical portion 1a of the reel unit 1, the uneven strip 1b and the locking claw 9 are not exposed to the outside.
Seawater, sand, dust, etc. will not adhere and will not enter the drag adjustment knob 8 and interfere with the relaxation prevention / moderation action.

Since only the locking claw 9 is fixed to the drag adjusting knob 8, the number of parts is reduced, the structure is simple, and the workability of assembly is improved.

[Effect of device]

Since the present invention is configured as described above, the male screw can be formed on the outer periphery of the rear cylindrical portion of the reel unit by molding, so that the manufacturing is easy and the manufacturing cost can be reduced. In addition, the locking claw is fixed inside the drag adjustment knob, and the uneven strip is formed in the rear cylindrical part of the reel unit so that the uneven strip and the locking claw are not exposed to the outside, so seawater, sand, dust, etc. adhere. Or
It does not enter into the knob and interfere with the relaxation prevention and moderation action. Furthermore, since the locking claw is only fixed to the drag adjustment knob, the number of parts is reduced, the construction is simple and the workability of assembly is improved. Can be provided.
