Description

[Detailed Description of the Invention] This invention provides 6j! by heat-treating a synthetic resin buffer ring.
'ffl A method of manufacturing a fishing line guide with a fixed fishing line kite platform VC.

Conventionally, a fishing line guide consisting of an inner hard fishing line guide ring, an intermediate buffer ring, and an outer metal outer ring was introduced in Japanese Utility Model Publication No. 48-5574.
As seen in Publication No. 7, the metal outer ring is first fitted into the concave groove of the buffer ring, and then the fishing line guide ring is press-fitted inside, but the press-fitting operation must be performed for each ring. At the same time, this press-fitting operation causes deformation or damage of each item, making manufacturing extremely troublesome.Furthermore, there is a defect that the fishing line guide ring easily falls off due to temperature changes, shocks, etc., and the size and weight increase. There are also drawbacks.

It is also known from Japanese Patent Publication No. 51-35 that a synthetic resin material is injection molded between the inner and outer metal rings, and this method maintains accuracy on the inner and outer surfaces. However, if the inner fishing line guide ring is difficult to maintain high precision like ceramics, synthetic resin material is used [7], which makes molding difficult, and the inner fishing line guide ring is made of metal. Currently, it is only possible to use it.

A concave groove is formed in the circumferential direction on the outer periphery of the fishing line guide ring,
Pour a liquid resin such as adhesive into this groove and build it up [2. After this solidifies, the built-up part is cut 1 to make it flat, and a fixing ring is fitted into the soil to fix the fishing line. A guide is known from Japanese Unexamined Patent Publication No. 53-150180. However, pouring the liquid resin into the circumferential groove of the guide ring and building up the material is troublesome and takes time, and it is difficult to build up the material uniformly, resulting in a large amount of wasted material.

SUMMARY OF THE INVENTION An object of the present invention is to propose a method for threading an 11-line guide, which has good workability and can securely fix a hard fishing line guide ring that is difficult to achieve dimensional accuracy.

As described above, the present invention will be explained with reference to the illustrated embodiments.
As shown in the figure, there is a through hole 1a in the metal plate frame 1 of the top guide.
This metal plate frame 11/C synthetic resin buffer ring 2 is integrally molded. The synthetic resin buffer ring 2 is molded to form a through hole 2a on the inner periphery of the through hole 1a, and the outer periphery is molded so as to hold the metal plate frame 1 with thick parts 2b and 2c. Next, a hard fishing line kite JJ13 is inserted into the through hole 2a of the synthetic wood buffer cylinder 2 molded into the metal plate frame 1 as shown in Fig. 80"C to 160
Heat to ℃. The heating time is, for example, 1 hour.

The synthetic resin buffer ring 2 heated at the above temperature is rapidly cooled from the special high temperature during molding to eliminate the internal strain generated [7] and to cause a shrinkage phenomenon, and the buffer ring 2 has a wall diameter of the through hole 2a as shown in Fig. 6. As the thickness decreases, the thick part 2 b, 2
c expands l1 in the width and thickness direction, and the wall of the through hole 2a @! In fact, a hard fishing line guide ring is fixed in close contact with the outer peripheral wall of the fishing line guide ring 5.

FIG. 4 shows a case where the fishing rod mounting leg 4 is fixed to a metal plate frame 1, and the manufacturing process is the same as the previous example.

As described above, since the present invention has a configuration Lfr, the hard fishing line guide ring is less likely to be damaged than the conventional example in which it is fixed by press fitting. Moreover, even if the outer circumference of the hard fishing line guide has no shape or accuracy, it can be fixed securely even if the precision dimension is not fi 11. The manufacturing process is also integrated with a metal plate frame [7] A hard fishing line guide ring is inserted into the through hole of a synthetic resin buffer ring (2) The work is easy as it only requires heating, and it can be used for large to small fishing line guides. It is possible to provide a method for manufacturing a fishing line guide that has excellent effects such as being able to be applied to
