Description

[Detailed Description of the Invention] This invention relates to a fishing reel body cover fixing structure in which the body cover of a body housing a group of fishing reel gears is fixed by a bundle shaft.

As shown in FIG. 1, the body and body cover of a conventional fishing reel have a body cover 2 fixed to the body 1 at several points around the periphery with concave and convex fitting portions A and set screws 8.

A group of gears and a bundle shaft 6 in the body 1 have radial ball bearings 3 and 4 attached to the inside of the body 1 and the body capper 2, and a hollow shaft 5 into which a bundle shaft 6 having a polygonal cross section is inserted is connected to both radial ball bearings 3. , 4, the spool 16 is slid back and forth by a spool sliding gear 5a fixed to the outer periphery of one end of the hollow shaft 5, and the rotor 1B is rotated by a driving gear 7a fitted to the outer periphery of the hollow shaft 5. There is.

The fact that the body cover 2 is fixed to the body 1 with a plurality of fixing screws 8 has the disadvantage that the number of parts is large and the assembly work is troublesome.

Further, when the body 1 and the body cover 2 have the concave-convex fitting portions A, there is a drawback that the mold becomes complicated.

Furthermore, when the body and the body cover are made of synthetic resin material for rust prevention and weight reduction, depending on the situation, the female thread insert-molded into the synthetic resin material may come out, or the body or body cover may be removed. Cracks or fissures may occur in the cover, making it easier for water to enter the body.
There are drawbacks such as the built-in gears and shafts becoming corroded more quickly.

In view of the above-mentioned drawbacks, the object of the present invention is to propose a structure for fixing the body cover of a fishing reel, which eliminates the need for a plurality of fixing screws and facilitates the attachment of the body and body cover and the assembly of the reel.

The feature of this invention is that a ball bearing for holding the bundle shirt I is attached to the approximate center of the body and body cover so that it cannot be removed inward from the body and body cover, and the body and body cover are bundled through this ball bearing. This was measured using a screw screwed into the shaft and bundle shaft.

Hereinafter, the present invention will be explained with reference to illustrated embodiments.

FIG. 2 shows a spinning reel in which the bundle can be converted from left to right.

The body 1 of the reel is formed into a substantially rectangular cup shape,
A body cover 2 is attached to this body in the form of a lid.

Projections 1a and 2a are formed outwardly at approximately the center portions of the body 1 and the body cover 2, respectively, and recesses 1b and 2b are formed at their centers, and through holes 1C and 2 are formed at the center of the bottom of the recesses.
C is formed.

A radial ball bearing 3.4 is fitted and fixed in each of the recesses 1b and 2b.

Both ends of a hollow shaft 5 are fitted into the inner rings of the radial ball bearings 3 and 4.

The center hole of the hollow shaft 5 is formed to have a polygonal cross section, and a handle shaft 6 having a polygonal cross section is fitted into the center hole.

As shown in FIG. 3, a female thread 6a is formed at the center of one end of the bundle shaft 6, into which a male thread 61a of a screw 61 is screwed.

The screw 61 has a male thread, a boss portion 61b, and a flange portion 6.
It is made of 1C.

An adjustment washer 62 is interposed between one end of the bundle shaft 6 and the boss portion 61b.

A bundle base 63 is fixed to the other end of the bundle shaft 6.

A concave portion 63a is formed on one end surface of the bundle base 63, and a protrusion portion 63b is formed at the center of the bottom surface of the concave portion.

A bundle 64 is attached to the other end of the bundle base 63.

A sealing O-ring 65 is inserted into the recessed portion 63a.

A spool sliding gear 5a is provided on the outer periphery of one end of the hollow shaft 5.
is provided.

The spool sliding gear 5a is meshed with a transmission gear 12 rotatably attached to the inner wall of the body 1 with flanged screws 11.

The transmission gear 12 is provided with an eccentric pin, and the eccentric pin is fitted into a slot of a slider 15 fixed to one end of the spool shaft 14, so that the spool shaft 14 is slid back and forth. ing.

A spool 16 is fixed to the other end of the spool shaft 14.

A drive gear shaft 7 is fitted onto the outer periphery of the hollow shaft 5.

The drive gear shaft is provided with a drive gear 7a and a gear 7b, the gear 7b is meshed with one of the transmission gears 12, and the drive gear 7a is meshed with the gear 17 fitted on the spool shaft 14, so that the rotor 18 be rotated.

After the hollow shaft 5 is fitted to the radial ball bearings 3 and 4 and the bundle shaft 6 is fitted and assembled to the hollow shaft, when the screw 61 is screwed to one end of the bundle shaft 6, both radial ball bearings 3 .

When the inner rings of the radial ball bearings 3 and 4 are tightened inwardly, the body 1 that supports the bearings and the body cover 2 are each drawn inward and fixed.

The tightening by the screw 61 is adjusted by rotating the bundle 64 and interposing the adjusting washer 62 so that the bundle 64 is appropriately tightened.

The hollow shaft 5 is provided with a length that allows some clearance between the protrusion 63b of the bundle base and the flange 61C of the screw 61.

A lid 19 is fitted into the body protrusion 1a on the screw side, and the O-ring 65 is inserted into the recess 2b of the body cover protrusion 2a on the bundle base 63 side to provide waterproofing.

Even when the bundle is converted from left to right, the lid 19 and O-ring 65 can be attached in the same manner as described above.

In the above description, a radial ball bearing is used as the ball bearing, but a thrust ball bearing may also be used.

One may be a radial ball bearing and the other may be a thrust ball bearing.

Furthermore, although it has been described that the bundle shaft is supported by the ball bearing via the hollow shaft, the bundle shaft may be directly supported by the ball bearing.

Since the present invention is configured as described above, the body and the body cover are fixed by attaching the bundle shaft, the conventional fixing work of fixing screws is omitted, and the number of parts is reduced.

In addition, since the body and body cover are tightened by the bundle shaft at approximately the center, approximately equal force is applied to the body and body cover periphery, which is an excellent feature such as preventing cracks from being tightly tightened at specific points. It is possible to provide an effective stopping structure for the body cover of a fishing reel.
