Description

A labor-saving fishing float device Technical Field

[0001] This invention relates to the field of marine or freshwater fishing machinery and equipment, specifically a labor-saving fishing float device. Background Technology

[0002] Traditional fishing gear typically consists of a fishing rod, fishing line, float, and hook. When a fish bites, the angler pulls the rod upwards and backwards to bring the fish out of the water.

[0003] However, when the fish that bites the hook is large, the force with which it pulls on the hook and line is considerable. If the angler is not strong enough, it will take a lot of effort and time to slowly reel the fish in, and they may even be dragged into the water along with the fishing rod. Therefore, a labor-saving fishing device is needed to help people catch big fish. Summary of the Invention

[0004] The purpose of this invention is to provide a labor-saving fishing float device, which addresses the problem in the prior art where fish are too strong, making it difficult for anglers to catch them successfully.

[0005] To address the technical problems existing in the prior art, the present invention adopts the following technical solution: a labor-saving fishing float device, characterized in that: it includes a watertight cavity structure, the watertight cavity structure containing a watertight cavity, the watertight cavity being connected to an external air source through a vent pipe, one end of the watertight cavity structure being connected to a fishhook or harpoon through a first fishing line, and the other end of the watertight cavity structure being connected to a second fishing line; when a fish pulls on the fishhook or harpoon, the watertight cavity structure is subjected to tension, causing the volume of the watertight cavity to increase, thereby increasing the buoyancy of the watertight cavity structure.

[0006] As a further embodiment of the present invention: the watertight cavity structure includes a cylindrical structure and a piston structure; one end of the cylindrical structure is an open end, and the other end is sealed to form a watertight end; the piston structure and one side of the watertight end of the cylindrical structure together form the watertight cavity, and the watertight end has a through hole communicating with a vent pipe; the piston structure can move within the cylindrical structure to change the volume of the watertight cavity.

[0007] As a further embodiment of the present invention: the first fishing line is connected to the piston structure, and the second fishing line is connected to the cylindrical structure; or, the first fishing line is connected to the cylindrical structure, and the second fishing line is connected to the piston structure.

[0008] As a further embodiment of the present invention: the piston structure includes a piston body and a guide rod; the piston body and the watertight end of the cylindrical structure together form the watertight cavity; the guide rod is disposed on the piston body near the open end and is arranged along the axial direction of the cylindrical structure, and the guide rod has a plurality of reverse teeth arranged along its length direction, with the reverse teeth facing the watertight end; one end of the guide rod is connected to the piston body, and the other end is connected to the first fishing line or the second fishing line; a guide cover is fixed to the open end, the guide cover is provided with a guide hole, the guide rod passes through the guide hole, a check block is hinged at the guide hole, and a torsion spring is provided at the hinge of the guide cover and the check block, so that the check block is pressed on the guide rod.

[0009] As a further aspect of the present invention, the guide cover is provided with a water passage hole.

[0010] As a further embodiment of the present invention: the guide rod is detachably connected to the piston body; the guide cover and the cylindrical structure are detachably connected.

[0011] As a further embodiment of the present invention: the piston structure and the watertight end of the cylindrical structure are connected by a spring.

[0012] As a further aspect of the present invention, the piston structure is made of a flexible material.

[0013] As a further aspect of the present invention: the maximum static friction between the first inner surface of the cylindrical structure near the watertight end and the surface of the piston structure is greater than the maximum static friction between the second inner surface of the cylindrical structure near the open end and the surface of the piston structure.

[0014] Beneficial effects of this invention:

[0015] 1. This invention is installed on the fishing line between the hook and the rod. When a fish bites the hook, during the pulling process between the fish and the angler, the cylindrical structure and piston structure of the watertight cavity structure of this invention are pulled apart, which increases the volume of the watertight cavity. This increases the water displacement of the watertight cavity structure and generates a large amount of buoyancy. The component of this buoyancy along the fishing line will help the angler pull the fish towards the shore, and the component of this buoyancy perpendicular to the fishing line will help the fish float to the surface.

[0016] 2. When using this invention, the greater the force with which the fish pulls the hook, the faster the volume of the watertight cavity increases, and the faster the buoyancy of the watertight cavity structure increases, thus generating a large amount of buoyancy more quickly to save the angler effort; the longer the fish pulls the hook, the greater the volume of the watertight cavity increases, and the greater the buoyancy of the watertight cavity structure increases, thus generating even more buoyancy to save the angler effort; therefore, the more force the fish pulls, the greater the buoyancy the device produces.

[0017] 3. Because the piston structure is subjected to significant water pressure underwater, the pulling force of a fish alone is insufficient to move it. Therefore, a spring connects the piston structure to the watertight end of the cylindrical structure. When the piston body is pressed near the watertight end, the spring exerts a pushing force on it. This spring force helps the fish overcome the water pressure and push the piston structure towards the open end when it bites. To prevent the spring from pushing the piston body away and creating buoyancy when the fish is not biting, the first inner surface of the cylindrical structure near the watertight end is made rough. This allows the static friction between the rough surface and the piston structure surface to prevent the spring from pushing the piston body away when the fish is not biting. The second inner surface of the cylindrical structure near the open end is made smooth. This significantly reduces the friction on the piston structure after it is pulled away from the first inner surface and reaches the second inner surface, making it easier for the fish to pull the piston structure towards the open end.

[0018] 4. This invention uses a flexible material as the piston body material. While improving water tightness, due to the characteristics of the flexible piston, its cross-sectional area will tend to decrease when it is stretched axially to a certain extent. This reduces the pressure of the piston body on the inner surface of the cylindrical structure, thereby greatly reducing the maximum static friction between the piston body and the inner surface of the cylindrical structure. When fish pull the hook, it will drive the guide rod to stretch the piston body axially, thereby reducing the maximum static friction between the piston body and the inner surface of the cylindrical structure, making it easier for the fish to pull the piston structure towards the open end.

[0019] 5. The present invention provides multiple inverted teeth in the direction of the guide rod length, which are directed toward the watertight end of the cylindrical structure. The inverted teeth cooperate with the anti-return block so that after the fish bites the hook, the piston structure can only move toward the open end of the cylindrical structure and cannot move toward the watertight end. This ensures that after the force of the fish pulling decreases, the piston structure will not be pressed back to the watertight end by the water pressure, and the watertight cavity structure can continue to maintain a large amount of buoyancy.

[0026] The present invention will now be described in detail with reference to the accompanying drawings:

[0027] Referring to Figure 1, a labor-saving fishing float device includes a watertight cavity structure 1, which contains a watertight cavity 2. When the watertight cavity structure 1 is placed in water, water cannot enter the watertight cavity 2. The watertight cavity 2 is connected to an external air source through a vent pipe 3. This external air source can be the atmosphere or an independent air supply source, such as a sealed air bladder filled with air. One end of the watertight cavity structure 1 is connected to a fishhook 5 or a harpoon through a first fishing line 4, and the other end of the watertight cavity structure 1 is connected to a second fishing line 6. When a fish bites the hook or is speared by the harpoon, pulling on the fishhook 5 or the harpoon, the watertight cavity structure 1 is pulled by the first fishing line 4 and the second fishing line 6, causing the volume of the watertight cavity 2 to increase, thereby increasing the buoyancy of the watertight cavity structure 1. In the initial state, the total buoyancy of the watertight cavity structure 1 in the water is less than its weight, so that the watertight cavity structure 1 can sink into the water with the fish hook. After the watertight cavity structure 1 is subjected to the tension of the first fishing line 4 and the second fishing line 6, which increases the volume of the watertight cavity 2, the total buoyancy of the watertight cavity structure 1 is greater than its weight, thus helping the angler to pull the fish out of the water.

[0028] Referring to Figures 1, 2, and 3, the watertight cavity structure 1 includes a cylindrical structure 7 and a piston structure 8. One end of the cylindrical structure 7 is an open end 71, and the other end is sealed to form a watertight end 72. The piston structure 8 fits tightly with the inner wall of the cylindrical structure 7. The piston structure 8 and one side of the watertight end 72 of the cylindrical structure 7 together form a watertight cavity 2. The watertight end 72 has a through hole that connects to a vent pipe 3, allowing external gas to enter or leave the watertight cavity 2 at any time, thus facilitating the increase or decrease of the volume of the watertight cavity 2. The piston structure 8 can move within the cylindrical structure 7, thereby changing the volume of the watertight cavity 2. When a fish bites the hook, it pulls on the hook 5 and the fishing line, causing the fishing line to pull the piston structure 8 towards the open end 71, thereby increasing the volume of the watertight cavity 2 and increasing the buoyancy of the watertight cavity structure 1.

[0029] There are two ways to connect the fishing line and the watertight cavity structure 1: 1. The first fishing line 4 is connected to the piston structure 8, and the second fishing line 6 is connected to the cylindrical structure 7; 2. The first fishing line 4 is connected to the cylindrical structure 7, and the second fishing line 6 is connected to the piston structure 8. Both connection methods allow the piston structure 8 to move towards the open end 71 after the fish bites the hook.

[0030] The piston structure 8 includes a piston body 81 and a guide rod 82; the piston body 81 and the watertight end 72 of the cylindrical structure 7 together form a watertight cavity 2; the guide rod 82 is disposed on the side of the piston body 81 near the opening end 71, and its length direction is along the axis of the cylindrical structure 7; the guide rod 82 has multiple reverse teeth along its length direction, and the reverse teeth are turned towards the watertight end 72; one end of the guide rod 82 is connected to the piston body 81, and the other end is connected to the first fishing line 4 or the second fishing line 6. (Corresponding to the two connection methods mentioned above); a guide cover 9 is fixed to the open end 71, and a guide hole is provided on the guide cover 9. The guide rod 82 passes through the guide hole, and a check block 92 is hinged at the guide hole. The check block 92 can be in the form of a sheet or a strip. A torsion spring is provided at the hinge of the guide cover 9 and the check block 92. The torsion spring applies torque to the check block 92, so that the check block 92 is pressed on the guide rod 82, thereby allowing the guide rod 82 to move towards the open end 71, but not towards the watertight end 72.

[0031] The guide cover 9 is provided with a water passage hole 91, so that water can freely enter and exit the cylindrical structure 7 through the opening end 71.

[0032] The guide rod 82 is detachably connected to the piston body 81, preferably by a threaded connection; the guide cover 9 and the cylindrical structure 7 are detachably connected, preferably by a threaded connection.

[0033] The piston structure 8 and the watertight end 72 of the cylindrical structure 7 are connected by a spring 11. The thrust of the spring 11 on the piston structure 8 helps it overcome water pressure and move towards the open end 71 when a fish bites. The piston structure 8 is made of a flexible material and is interference-fitted with the cylindrical structure 7. The maximum static friction between the first inner surface 101 of the cylindrical structure 7 near the watertight end 72 and the surface of the piston structure 8 is greater than the maximum static friction between the second inner surface 102 of the cylindrical structure 7 near the open end 71 and the surface of the piston structure 8. This can be achieved by making the first inner surface 101 a rough surface and the second inner surface 102 a smooth surface. In the initial state, when the piston structure 8 is located at the first inner surface 101 on the watertight end 72 side, the spring 11 is under compression. At this time, the thrust of the spring 11 on the piston structure 8 is balanced by the friction of the first inner surface 101 of the cylindrical structure 7 on the piston structure 8. When a fish bites the hook and pulls the fishing line, thereby actuating the piston structure 8, the guide rod 82 will axially stretch the piston body 81. Due to the characteristics of the flexible material piston, its cross-sectional area will tend to decrease when stretched to a certain extent, thus reducing the pressure of the piston body 81 on the inner surface of the cylindrical structure 7. This reduces the maximum static friction between the piston body 81 and the first inner surface 101 of the cylindrical structure 7, making it easier for the fish to pull the piston structure 8 towards the opening end 71, as shown in Figure 4. When the piston body 81 is further moved to the second inner surface 102, the friction force on the piston body 81 will decrease significantly. At this time, the thrust of the spring 11 and the pulling force of the fish on the piston structure 8 will overcome the water pressure and move the piston body 8 to the opening end 71, thereby increasing the buoyancy of the device.

[0034] Furthermore, the piston body 81 is a hollow structure so that when it is subjected to the pulling force of the guide rod 82, its cross-section shrinks inward more significantly, which helps to reduce the maximum static friction between the piston body 81 and the first inner surface 101 of the cylindrical structure 7 more quickly.

[0035] In use, as shown in Figure 5, one end of the watertight cavity structure 1 is connected to the first fishing line 4, and the other end is connected to the second fishing line 6. The other end of the first fishing line 4 is connected to the hook 5, and the other end of the second fishing line 6 is directly or indirectly connected to the fishing rod. When preparing on land, the piston body 81, along with the spring 11, is pressed against the first inner surface 101. At this time, the pushing force of the spring 11 on the piston body 81 is balanced by the frictional force of the first inner surface 101 on the piston body 81. Then, the watertight cavity structure 1, along with the hook 5 and the float 13, is thrown into the water. Water enters the space on the side of the opening end 71 of the watertight cavity structure 1 through the water passage 91, while the watertight end 72 side, together with the piston body 81, forms a watertight cavity 2, which is filled with air. At this point, the buoyancy of the watertight cavity structure 1 is less than its weight, so it sinks into the water along with the hook 5. One end of the vent pipe 3 is connected to the watertight cavity 2, and the other end is connected to the float 12, thus floating to the surface and connecting with the outside air. When a fish bites the hook, if it is a weak fish, its pulling force is insufficient to overcome the water pressure and friction to pull the piston body 81, so the device of this invention does not function, and the angler can easily catch the fish. However, when a stronger fish bites the hook, it will pull the hook with all its might, and the angler will engage in a "tug-of-war" with the fish by pulling the fishing rod. The enormous tension of the fishing line will pull the piston structure 8 to overcome friction and water pressure towards the open end 71, thus increasing the volume of the watertight cavity 2. This causes the buoyancy of the watertight cavity structure 1 to exceed its weight, causing it to rise. Outside air enters the watertight cavity 2 through the vent pipe 3 to maintain the pressure within the watertight cavity 2 and prevent the formation of a vacuum. The force diagram at this point is shown in Figure 6. When the fish bites the hook, a pulling force F2 is generated diagonally downwards along the fishing line. The angler lifts the rod diagonally upwards along the fishing line, generating a pulling force F1. Meanwhile, the buoyancy force F3 on the watertight cavity structure 1 is directed directly upwards. F3 along the fishing line will generate a pulling force F31 in the same direction as F1, helping the angler lift the rod. F3 also generates a component force F32 perpendicular to the fishing line. F32 will pull the watertight cavity structure 1 and the fish upwards, making it easier to pull the fish out of the water. Furthermore, F32 pulls the fish to a shallower area, which helps reduce the water pressure applied to the piston structure 8 and makes it easier for the fish to pull the piston structure 8 towards the opening end 71, thereby increasing the buoyancy on the watertight cavity structure 1 and forming a positive feedback loop. Meanwhile, since the force with which fish pulls on the hook 5 varies, in order to prevent the piston structure 8 from moving towards the watertight end 72 under the action of water pressure when the force with which fish pulls on the hook 5 decreases, the guide rod 82 and the check block 92 provided in this invention can cooperate with each other so that the piston structure 8 can only move unidirectionally towards the open end 71 and cannot move towards the watertight end 72. When the piston structure 8 moves towards the watertight end 72 under the influence of water pressure, the check block 92 will abut against the back teeth to prevent the piston structure 8 from moving towards the watertight end 72, thereby ensuring that the buoyancy of the watertight cavity structure 1 only increases and does not decrease.

[0036] The above examples are only used to illustrate the present invention. The orientation, structure, material, and connection method of each component can be varied. Any equivalent transformations and improvements made on the basis of the present invention should not be excluded from the protection scope of the present invention.
