Abstract

The present invention relates to a fishing sinker having a weight adjustment device using volume change. According to the present invention, the fishing sinker is composed of an upper cap and a lower cap that are screwed to each other such that an internal void is expanded or shrunk by fastening or loosening screw in a sealed state, and is hung to an end of a fishing gut to allow a fishing hook to sink under the water. The volume of the fishing sinker changes according to the degree of a screw fastening, so the pressure acting on the fishing sinker is increased/decreased in proportion to the amount of a volume increase/decrease of the sinker when the sinker is sunk under the water, and thus the weight of the sinker can be easily adjusted to correspond to the buoyancy of a float. According to the present invention, the sinker is composed of the upper and lower caps that are screwed to each other, wherein the upper cap comprises: a cylindrical sleeve provided on outer portion thereof to guide insertion of screw for screwing; and a screw rod formed to be located on a concentric line therein while maintaining a gap from the inner circumferential surface of the sleeve, and the lower cap comprises: a screw groove screwed to the screw rod in correspondence thereto; and a screw tube having one or more rings provided on an upper outer circumferential surface thereof to serve a sealing function. Thus the lower cap is inserted or separated through the gap between the sleeves, and the volume is changed while the internal space of the screw groove is reduced or expanded in the sealed state according to the degree of the screwing between the upper and lower caps, so the weight of the sinker under the water is added or reduced in proportion to the amount of the volume change thereof.

Description

FIELD OF THE INVENTION The present invention relates to fishing vessels having a weight adjusting device for changing a volume of a fishing vessel,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing rod having a weight adjusting device by a volume change, and more particularly, The upper cap and the lower cap are mutually screwed to each other so as to be reduced or enlarged so that the volume is changed according to the degree of screw connection so that when the bolls are submerged in water, The present invention relates to a fishing rod having a weight adjusting device by which the weight of the rod is increased or decreased by a pressure difference so that the weight of the rod can be easily adjusted according to the buoyancy of the fishing rod.

In general, the bongle hangs at the end of the fishing line, and the fishing needle with the bait sinks at a desired point, and a load corresponding to the buoyancy force of the crucible for capturing the fishy nibble is visually recognized, And the like.

That is, in order to satisfy the use conditions of the crucible, it is desirable that the weight of the bongle and the buoyancy of the crucible are balanced with each other. However, even when the two components are equal to each other, So that during the fishing, we adjusted the weight of the bongle or adjusted the buoyancy of the crucible.

As a general method for performing the above-mentioned crushing, a part of a lead rod 1 or a lead balloon 2, which has a large specific gravity and is easy to cut, is hanged from the fishing line and used as shown in Figs. 1A and 1B The weight of Bongdol was adjusted so as to correspond to the buoyancy of the tongue.

However, lead is a heavy metal, and if it is accumulated in the body even if a trace amount is accumulated in the body, it is not properly excreted. It accumulates in the protein and shows side effects over a long period of time. Thus, it is a fatal danger to human body. , But its use is gradually regulated because it has adverse effects on plants and animals according to the food chain.

In the conventional art for adjusting the weight of the fishing weights, an insertion groove is formed in the center of a plurality of partition plates, and a fitting hole is provided for fitting the fishing line from one side of the outer circumferential surface of the partition plate to the insertion groove , The insertion groove is formed to be larger than the outer diameter of the body portion of the support frame so that the insertion groove can be fixed to the engagement protrusion of the support frame and then fixed by the upper fixing member. .

The fishing weighing assembly is a fishing weighing assembly in which a plurality of (n) number of partition plates having different thicknesses for fishing are combined so that the weight of the fishing weights can be finely adjusted so as to have a sinking force corresponding to the buoyancy of the crucible So that the user can quickly and precisely and quickly adjust the balance.

However, the above-mentioned technique has a problem in that a plurality of ring members are combined with the main body of the registered utility model publication No. 301437 disclosed before the application to adjust the weight according to the number of the ring members, and a plurality of registrants of the registered utility model No. 381258 Compared with a fishing tackle made of stainless steel to prevent environmental pollution while adjusting the weight by adjusting the weight of the partition plate, a fitting hole is formed on one side of the outer circumferential surface of the partition plate to fit the fishing line, In this case, however, there is a problem in that it is inconvenient not only for the operation of inserting and removing the small partition plate, but also for the loss of the room.

The present invention has been made in view of the structural problems of the fishing weights in which the weight of the dividing plate or the ring member is adjusted by adjusting the weight of the dividing plate or the ring member. The present invention also provides a fishing rod having a weight adjusting device for changing the volume of the fishing rod so that the weight of the fishing rod can be increased or decreased in proportion to the amount of volume change so that the volume of the fishing rod is reduced or enlarged in the sealing state.

In order to accomplish the above object, the present invention provides a golf club head comprising: an upper cap and a lower cap which are threadedly coupled to each other at an end of a fishing line, the cylindrical cap having a cylindrical sleeve A spiral rod is formed so as to be positioned on a concentric line while maintaining a gap from the inner circumferential surface of the sleeve, and the lower cap is provided with a spiral groove threadedly corresponding to the spiral bar and one or more rings sealing the upper face of the spiral groove The inner space of the spiral groove is reduced or enlarged in a sealed state according to the degree of screw connection between the upper and lower caps, The weight of the bengal is added or subtracted in water in proportion to the volume change.

In the fishing barbell having the weight adjusting device according to the present invention, the weight of the barb corresponding to the buoyancy of the crucible is selected and used. The screws of the upper and lower caps are tightened or loosened, The weight is slightly increased or decreased. Therefore, it is possible to prevent the component from being lost due to the simple and quick collapse of the component.
