Description

A SINKER FOR FISHING OF FRESH WATER}

The present invention relates to a freshwater fishing rod, and more particularly, in forming an inner space that generates buoyancy by the upper body and the lower body, so that the air is circulated without distributing water through the gap where the upper body and the lower body are combined. And by forming a large angle of the spiral groove that the upper body and the lower body is combined to be able to quickly enlarge or reduce the volume of the space in the inside of the pedestal can be quickly adjusted to the extent necessary to the weight of the pedestal, such as reservoir or steel It relates to a freshwater fishing rod that can prevent the surrounding environment of the fishing ground, including the water quality of the heavy metal contamination.

In general, when freshwater fishing in reservoirs, rivers or lakes, lead rods are used to make the buoyancy of the float, or the height of the float, appropriate to the float height depending on the specific gravity of the water or turbidity of the water. You can control the buoyancy of the bobber by cutting or adding the weight of the bumper.

In other words, after attaching a hook and a hook to the fishing line and put the bobber, and put it in the water to cut the bobber according to the injured condition of the bobber.

The reason why the weight balance between the bobber and the stick is properly adjusted is to ensure that the bobber floats at the optimum state on the surface of the fish and keeps the catch at all times according to the quality of the fish. It is an important factor to determine the weight, and the weight of the boulder or bobber should be precisely adjusted so that the bobber floats to the proper height above the water surface according to the depth of the fishing ground and the specific gravity of the water.

Bongdol has the function of sinking the hook and allowing the bobber connected to the upper part to float properly in water.If Bongdol is heavier than the bobber, the bobber sinks below the surface and cannot be identified. Due to the buoyancy of the bobber, the bobber rises too sensitively, so the weight of the bondol should be properly adjusted.

By the way, Bongdol, the buoyancy control means of this type, uses lead rods made of lead (pb), which is very harmful to animals and plants as well as the human body. Because the fishing float is set at the height of the float, it takes a lot of time to adjust the buoyancy of the bob, and the shaved lead contaminates the surrounding environment.

In other words, if the fishing rod is detached several times in order to adjust the weight of the fishing weight in the fishing ground and the fishing needle is caught by a few seconds or caught in a stone and it is difficult to remove it from the water, the fishing rod is cut off together with the fishing line. Since it is thrown away as it is, the water quality is contaminated by the lead rod, which causes serious damage not only to humans who use the polluted water as drinking water, but also to fish and plants living in the water. Due to the current situation that seriously pollutes the environment around the fishing grounds, abandoned lead eventually accumulates in the human food along the food chain has a terrible effect.

Therefore, in order to solve such an end, a bumper for adjusting the weight by allowing the buoyancy to be arbitrarily adjusted has been developed and registered as Utility Model Registration No. 20-235462. The bongdol is a spiral coupling between the upper body and the lower body, and the gap between the upper body and the lower body is sealed so that it takes much time to control the volume of the space between the upper body and the lower body, and the longitudinal centers of the upper body and the lower body coincide with each other. There is a problem that is not twisted, the screw portion joining the upper body and the lower body is freely unwinded or wound, the volume of the internal space is changed freely and accordingly there was a problem that can not adjust the buoyancy of the rod as desired.

The present invention has been made in order to solve the conventional problems as described above, the object of the present invention is to adjust the buoyancy quickly and do not arbitrarily change the adjusted buoyancy, fresh water fishing rods that can prevent environmental pollution To provide.

Fresh water fishing rods according to the present invention for achieving the above object is a fixed hole is formed in the center of the upper end and a spiral groove is formed on the inner circumferential surface and the cylindrical upper body with the bottom open, the upper body is inserted into the open bottom of the upper body and It is to be able to adjust the volume of the inner space is formed together, the fixing hole is formed in the center of the lower end of the packing is formed and the guide projection is inserted into the spiral groove of the upper body is formed on one side of the upper outer surface and the upper body is open And a support penetrating the upper body and the lower body to be welded and fixed to the fixing hole of the upper body, the support being penetrated through the packing part of the lower body, and the weight stored in the inner bottom of the lower body. It is done.

Freshwater fishing rods of the present invention, the support is also characterized in that the upper and lower support parts are connected to each other by welding, the hook is rotated to the upper and lower ends.

Fresh water fishing rod of the present invention, the spiral groove of the upper body is Characterized in that formed at an angle of 20 °.

Freshwater fishing rods according to the present invention when the size of the inner space of the upper and lower body of the bondol is large or small, the clearance between the upper body and the lower body so that only the air flows through the gap is formed so that the inner space of being able to quickly adjust the volume thereby it can be adjusted quickly and precisely according to the weight of the water specific gravity of the fishing bongdol.

In the present invention, since the support penetrates the center of the upper body and the lower body, and the upper body and the support are welded, and the lower body and the support are closely contacted by the packing, the coupling state of the upper body and the lower body and the volume of the inner space are not arbitrarily changed. The buoyancy adjusted by the user does not change arbitrarily.

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

Freshwater fishing rods according to the present invention supports the upper body 10 of the bottom open cylindrical bottom, the lower body 20 is inserted into the open bottom of the upper body 10, the upper body 10 and the lower body 20. The support 30 is comprised from the weight 40 accommodated in the said lower body 20. As shown in FIG.

The upper body 10 has a fixing hole 11 through which a support 30 to be described later is penetrated and welded, and a bottom thereof is opened.

On the inner circumferential surface of the upper body 10, a spiral groove 12 is formed so that the guide protrusion 23 of the lower body 20 to be described later can be inserted and rotated, and the inclination angle of the spiral groove 12 is gentle. It is generally formed at a large inclination angle rather than an inclination angle.

The reason is that if the size of the pedestal (A) is to be made small in order to make the weight of the pedestal (A) heavy, the lower body (20) is quickly inserted into the upper body (10), or the weight of the pedestal (A) In order to lighten the size of the pedestal (A) to increase, the lower body 20 is to quickly come out from the inside of the upper body (10).

The inclination angle of the helical groove 12 is preferably about 20 degrees.

The lower body 20 has a fixing hole 22 having an upper side open and a hollow packing 21 inserted therein. Guide protrusions 23 are formed at one end of the outer circumferential surface of the lower body 20 to be rotated while being guided by being inserted into the spiral groove 12 of the upper body 10.
The lower body 20 is inserted into the bottom of the upper body 10 and the guide protrusion 23 is inserted into the spiral groove 12 to adjust the insertion depth of the lower body 20 by rotating the lower body 20 relative to the upper body 10. The volume of the inner space of the lower body 20 and the upper body 10 can be adjusted, thereby adjusting the buoyancy.

The support 30 is composed of an upper support 31 and a lower support 32. The upper end portion of the upper support part 31 is connected to the ring-shaped hook hole 31a to be rotated, and the lower end portion of the lower support part 32 is connected to the ring-shaped hanger 32a to be rotated.

The upper support portion 31 is fixed to the fixing hole 11 and the upper support portion 31 in contact with the fixing hole 11 in a state of passing through the fixing hole 11 of the upper body 10 by welding. The lower support part 32 is inserted into the hollow part of the packing 21 which is inserted into the fixing hole 22 of the lower body 20 so as to be rotatable.

The lower end portion of the upper support portion 31 and the upper end portion of the lower support portion 32 of the support 30 are assembled with the bumps A, and then welded to each other. That is, it is comprised so that it may weld in the state which contact | connected the upper end part of the lower support part 32, after pushing the upper body 10 downward in the state which the pedestal A was assembled to come out of the lower side.

As described above, according to the present invention, the guide protrusion 23 of the lower body 20 is inserted into the spiral groove 12 of the upper body 10 so that the guide protrusion 23 is rotated through the spiral groove 12. 20 is a structure that allows the lower body 20 to enter the inside of the upper body 10 or from the inside of the upper body 10, the lower body 20 is stable along the support 30 when the relative rotation with the upper body 10. The lower body 20 does not rotate by itself unless an external force is applied to the lower body 20.

The hooks 31a and 32a on the upper and lower sides of the support 30 can be rotated so that the fishing line 60 is not twisted and the fishing gears such as the bobber 50 can be smoothly positioned at the correct positions. Will be.

The weight 40 has an insertion hole 41 is formed in the center portion is formed in a cylindrical shape with a low height. The weight 40 is placed in the lower side of the lower body 20 in a state where the support 30 penetrates the insertion hole 41.

The operation of the freshwater fishing rod of the present invention configured as described above will be described.

First, the upper support part 31 connected to allow the hooking tool 31a to be rotated through the fixing hole 11 of the upper body 10, and then the upper part of the upper support part 31 is in contact with the fixing hole 11. The upper support 31 is fixed to the fixing hole 11 by welding.

Then, the weight 40 is inserted into the lower side of the lower body 20 to be placed therein, and the packing 21 is inserted into the fixing hole 22 formed at the center of the bottom surface of the lower body 20 to fix and tightly attach the lower body 20. Guide protrusions 23) are inserted into the spiral grooves 12 of the upper body 10.

Then, by lowering the lower body 20, the lower body 20 rises to the upper side inside the upper body 10, and the lower part of the upper support part 31 is inserted into the hole 41 and packing of the weight 40 of the lower body 20. After passing through the hollow part of (21), it comes out of the lower side and is exposed.

Then, the upper surface of the lower support part 32 connected to the lower end so as to be rotated so as to contact the bottom surface of the upper support part 31 so as to rotate the hook 32a is completed assembling the rod A.

Therefore, as shown in Figure 4, the fishing line 60 is connected to the bobbin (50) by the fixing ring 51 of the rubber material and the hook (31a) of the support 30 of the rod (A) of the present invention When the fishing line 60 is connected to the hook (A) of the support 30 of the support 30, hook the fishing line (70) is connected to the fishing line (70) connected to the fishing needle (70) When the fishing is ready to complete and throwing the fishing gear, such as the bondol (A) connected to the fishing line 60 in the water, such as a reservoir.

To adjust the buoyancy of the bobber 50, hold the upper body 10 with the left hand and hold the lower body 20 with the right hand, and then turn the lower body 20 clockwise from the center of gravity point B as the lower body 20. As the space portion between the upper body 10 and the lower body 20 becomes larger as the outer body 10 emerges from the inside of the upper body 10, the weight of the bondol A becomes lighter. Indicates)

On the contrary, when the lower body 20 is turned counterclockwise from the center of gravity point B, the lower body 20 enters the upper body 10 while the space between the upper body 10 and the lower body 20 becomes smaller. The weight of (A) becomes heavy.

By simply turning the lower body 20 in this way, the weight of the pedestal A becomes the desired weight, so that the buoyancy of the bobbin 50 can be easily adjusted. And since the inclination angle of the spiral groove 12 formed on the inner circumferential surface of the upper body 10 has a large angle of 20 °, the lower body 20 can quickly enter and exit the inside of the upper body 10, so that the bumps ( It is possible to quickly adjust the size of the space inside the A).

Bondo (A) of the present invention is formed between the upper body 10 and the lower body 20 is a gap through which air can be distributed, but a small gap is formed so that the water can not be passed through the cup in the state of use As it is put upside down in the water, water does not enter the internal space of the bondol (A).

And once the buoyancy adjustment is completed, because the welded between the support 30 and the upper body 100 and the packing 21 is formed between the support 30 and the lower body 20 unless the user applies an external force Optionally, the coupling state of the upper body 10 and the lower body 20 does not change, and thus the volume of the inside does not change and the buoyancy does not change arbitrarily.

The weight 40 is formed in a small, medium, large according to the size of the bobber (50), the weight 50 is a fixed weight and fine control of the weight of the bondol (A) as described above Adjust with buoyancy.

When lowering the buoyancy of the pedestal (A) by turning the lower body (20) too much with the bobber (50) sinks to the bottom, and if you raise the buoyancy of the pedestal (A) by turning the lower body (20) Is properly floated on the water surface to be in an optimal state, if the buoyancy of the pedestal (A) is raised too much, the pedestal (A) is light, so that the bobber (50) is too injured out of the water surface.

As described above, when adjusting the size of the inner space of the bondol (A) consisting of the upper body 10 and the lower body 20 according to the present invention, it is easy to space volume inside the bondol (A) and It is designed to be adjusted quickly and after one buoyancy adjustment, it is very convenient to use because it does not change arbitrarily unless the user intentionally applies external force.

And, Even if you need to change the bobber for fishing damage or loss during fishing, you can use it as a simple adjustment without cutting the buddle for changing or sticking it.

In addition, because the existing fishing only checks the buoyancy of the float, the fine mouth does not change the tail, but the present invention can receive a buoyancy of the float, the buoyancy of the bondol at the same time can be caught in the fine mouth, so you can catch a lot of meat. .

Although the present invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that various changes and modifications can be made within the technical scope of the present invention, and such modifications and modifications belong to the appended claims.
