Adjustable buoyancy fishing float

Abstract

The present invention relates to fishing supplies, specifically an adjustable buoyancy fishing float. At present, when faced with lead sinkers, fishhooks and baits of different weights, fishing floats sometimes fail to float, or float up excessively high, making it difficult to determine whether a fish has bitten. The objective of the present invention is to provide an adjustable buoyancy fishing float that provides a relatively wide buoyancy adjustment range and eliminates the need for lead trimming during float adjustment. The technical solution of the present invention is as follows: comprising a float tail, a float body, a float foot, etc. A cylinder, a piston, a piston ring, etc. are provided within the float body; the piston is connected to the float tail, and a penetrating through-hole runs from the float body, through the cylinder, the piston, etc. to the float tail. The volume of the cylinder can be adjusted by pressing or pulling the float tail, the float tail having scale numbers marked thereon. Two ends of the cylinder inside the float body are filled with a lightweight material. A sealing gasket is provided at the contact point between the float tail and the float body to prevent water from entering the cylinder. In a luminous float based on the present adjustable buoyancy fishing float, a battery compartment, a luminous light, etc. are arranged on the float tail. The present invention has the beneficial effects of providing a relatively wide buoyancy adjustment range, involving simple buoyancy adjustment, and eliminating the need for lead trimming during float adjustment.

Description

An adjustable buoyancy float Technical Field

[0001] This invention relates to fishing supplies, specifically an adjustable buoyancy float. Technical Background

[0002] Currently, fishing floats generally have a fixed buoyancy. When faced with sinkers, hooks, and baits of varying weights, the float sometimes fails to rise, rises too much, or the number of segments on the float tip is inconsistent, making it difficult to determine if a fish has been hooked. The technical solution disclosed in application number 201720194586.9 claims to allow buoyancy adjustment, but the air chamber is very small, the adjustment range is limited, and the upper and lower parts of the float are stepped with exposed threads, which does not conform to anglers' aesthetic preferences and streamlined sensitivity design, making it difficult to promote. The technical solution disclosed in application number 201720219187.3, in order to achieve a streamlined design, has a smaller spiral piston, resulting in an even lower buoyancy adjustment range. I calculated that its buoyancy adjustment range is only about 0.2 grams, making its functionality impractical. A buoyancy range of 1-3 grams is generally considered practical for floats. To increase the buoyancy adjustment range, the air chamber needs to be enlarged, which requires an exhaust channel, but neither of the aforementioned two patents has an exhaust channel. Summary of the Invention

[0003] The purpose of this invention is to provide an adjustable buoyancy float with a streamlined design that appeals to anglers, a relatively large buoyancy adjustment range, and simple and clear buoyancy adjustment, without the need to cut lead sheets.

[0004] The technical solution adopted in this invention is: an adjustable buoyancy float, including a float tip, a float body, and a float stem. A cylinder, piston, piston rings, etc., are installed inside the float body. The piston is connected to the float tip. A through-hole extends from the float body through the cylinder and piston to the float tip. Water enters through the through-hole in the float body and the cylinder, while air is discharged through the through-hole in the piston and the float tip.

[0005] Furthermore, pressing or pulling the float tip can adjust the cylinder volume, thereby adjusting the buoyancy of the float. The float tip is marked with scale numbers to indicate the magnitude of buoyancy achieved by pressing or pulling the float tip.

[0006] Furthermore, the cylinder inside the float has a streamlined shape at both ends, preventing the piston from entering. Therefore, it is filled with lightweight foam material at the top and bottom to prevent water from entering and filling, thereby increasing the buoyancy. The bottom foam has through holes that connect with the through holes in the float body.

[0007] Furthermore, a sealing ring is installed at the sliding contact point between the float tip and the float body to prevent water from entering the cylinder.

[0008] Furthermore, for the luminous float of this adjustable buoyancy float, the battery compartment, electronic components, and lights are located on the float's tail.

[0009] Furthermore, the presence of gas and a certain degree of vacuum within the cylinder allows for larger piston rings, enabling the piston to be locked against the cylinder wall for positioning.

[0010] The beneficial effects of this invention are: the streamlined shape of the float conforms to the sensitivity design and the aesthetics of anglers; the buoyancy adjustment range is relatively large; adjusting the buoyancy is simple and clear; and adjusting the float does not require cutting lead.

[0013] The following is a detailed description in conjunction with the accompanying drawings. Detailed Implementation

[0014] An adjustable buoyancy float includes a float tip 4, a float body 2, and a float stem 1. The float body 2 contains a cylinder 14, a piston 10, and a piston ring 13. The piston 10 is connected to the float tip 4. A through-hole is formed from the float body 2 through the cylinder 14 and piston to the float tip. Water enters through the through-hole 6 in the float body, the through-hole 9 in the lower foam section, and the cylinder 14. Air is discharged through the through-hole in the piston 10 and the through-hole 7 in the float tip.

[0015] Furthermore, pressing or pulling the float tail 4 can adjust the volume of the cylinder 14 to adjust the buoyancy. The float tail 4 is marked with a scale number 3 to indicate the magnitude of buoyancy achieved by pressing or pulling the float tail 4.

[0016] Furthermore, the cylinder 14 inside the float body 2 has a streamlined shape at both ends, so the piston 10 cannot enter. Therefore, it is filled with lightweight material of upper foam 11 and lower foam 8 to prevent water from entering and filling, thereby increasing the buoyancy. The lower foam 8 is provided with a lower foam through hole 9 that is connected to the float body through hole 6.

[0017] Furthermore, a sealing ring 12 is provided at the sliding contact point between the float tail 4 and the float body 2 to prevent water from entering the cylinder.

[0018] Furthermore, for the luminous float of this adjustable buoyancy float, the battery compartment 5, electronic components, and lights are located on the float tail.

[0019] Furthermore, the cylinder 14 contains gas and also has a certain degree of vacuum, which can increase the size of the piston ring 13 and allow the piston 10 to be locked onto the inner wall of the cylinder 14 for positioning.
