Buoy with adjustable buoyancy

Abstract

The invention relates to fishing supplies, in particular to a buoy with adjustable buoyancy. At present, when facing lead weights, fishhooks and baits with different weights, fishing buoys cannot float or float too much sometimes, and whether fishes are fished or not is not attractive. The invention aims to provide the buoyancy-adjustable buoy which is relatively large in buoyancy adjustment range and does not need to shear a lead sheath during buoy adjustment. According to the technical scheme, the float comprises a float tail, a float body, a float foot and the like. A cylinder, a piston, a piston ring and the like are arranged in the float body, the piston is connected with the float tail, and a through hole is formed from the float body to the float tail through the cylinder, the piston and the like. The volume of the air cylinder can be adjusted by pressing or pulling the float tail, and scale numbers are marked on the float tail. Two ends of the cylinder in the float body are filled with light materials. A sealing ferrule is arranged at the contact position of the float tail and the float body to prevent water from entering the cylinder. According to the floating buoy with the adjustable buoyancy, the battery bin, the luminescent lamp and the like are arranged on the buoy tail.

Description

[0001] The invention relates to fishing supplies, in particular to a float with adjustable buoyancy. Background Art

[0002] At present, fishing floats generally have fixed buoyancy. When facing different weights of lead sinkers, fish hooks, and baits, the float sometimes cannot float, or floats too much, or the number of float tails is uncertain, which makes it difficult to see whether fish are caught. The technical solution published in application number 201720194586.9 claims that the buoyancy can be adjusted, but the air chamber is very small, the adjustment range is very small, and the upper and lower parts of the float are stepped, with exposed threads, which does not meet the aesthetics of anglers and the streamlined sensitivity design, and is difficult to promote; the technical solution published in application number 201720219187.3, in order to take into account the streamlined design, its spiral piston is made smaller and the buoyancy adjustment range is lower. The inventor has calculated that its buoyancy adjustment range is only about 0.2 grams, and the functional practicality is not high, while the buoyancy range of the float is generally between 1-3 grams to be practical. In order to increase the buoyancy adjustment range, the air chamber must be enlarged, and the enlarged air chamber must have an exhaust channel, and the aforementioned two patents do not have an exhaust channel. Summary of the invention

[0003] The purpose of the present invention is to provide an adjustable buoyancy float with a streamlined design that conforms to the aesthetic tastes of anglers, has a relatively large buoyancy adjustment range, and is simple and clear in adjusting the buoyancy, and does not require cutting lead foil to adjust the float.

[0004] The technical solution adopted by the present invention is: an adjustable buoyancy float, including a float tail, a float body, a float foot, etc. A cylinder, a piston, a piston ring, etc. are arranged in the float body, the piston is connected to the float tail, and a through hole is provided from the float body through the cylinder, the piston, etc. to the float tail, water enters from the through hole of the float body and the cylinder, and air is discharged from the through hole of the piston and the float tail.

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

[0006] Furthermore, the two ends of the cylinder in the float body are streamlined, and the piston cannot enter, so upper foam lightweight material and lower foam lightweight material are used to fill them to prevent water from coming in to fill them, thereby increasing the buoyancy of the float. The lower foam has a through hole that penetrates the through hole of the float body.

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

[0008] Furthermore, for the luminous float of the adjustable buoyancy float, the battery compartment, electronic accessories, luminous lights, etc. are arranged on the tail of the float.

[0009] Furthermore, there is gas in the cylinder and also a certain degree of vacuum, so the piston ring can be enlarged and the piston can be clamped on the inner wall of the cylinder to be positioned.

[0010] The beneficial effects of the present invention are as follows: the streamlined shape of the float meets the sensitivity design and the aesthetic taste of anglers, the buoyancy adjustment range is relatively large, the buoyancy adjustment is simple and clear, and the float does not need to be cut.

[0013] The following is a detailed description with reference to the accompanying drawings. DETAILED DESCRIPTION

[0014] An adjustable buoyancy float comprises a float tail 4, a float body 2, a float foot 1, etc. A cylinder 14, a piston 10, a piston ring 13, etc. are arranged in the float body 2, the piston 10 is connected to the float tail 4, and there is a through hole from the float body 2 through the cylinder 14, the piston, etc. to the float tail, water enters from the float body through hole 6, the lower foam through hole 9, and the cylinder 14, and air is discharged from the piston 10 through hole and the float tail through hole 7.

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

[0016] Furthermore, the two ends of the cylinder 14 in the float body 2 are streamlined, and the piston 10 cannot enter, so the upper foam 11 lightweight material and the lower foam 8 lightweight material are used to fill it to prevent water from coming in to fill it, thereby increasing the buoyancy of the float, wherein the lower foam 8 is provided with a lower foam penetration hole 9 that is connected to the float body through hole 6.
