Description

Technical Field

[0001] This utility model belongs to the technical field of fish sorting tools, specifically relating to fish sieving balances. Background Technology

[0002] Lure fishing, often called "water golf," is an elegant sport that prioritizes environmental protection and optimizes the natural environment. Lure fishing, also known as artificial bait fishing, is a method that mimics small creatures to provoke attacks from larger fish. Throughout the fishing process, the angler engages in full-body exercise, a stark contrast to traditional fishing methods. With the booming development of lure fishing competitions, fish selection is a crucial part of the competition process, and its efficiency and accuracy directly impact the fairness of the competition and the participants' experience.

[0003] Currently, fish sorting is mainly done by weighing each fish individually using electronic scales. While electronic scales can accurately measure the weight of fish, in practice, if the length of the fish needs to be measured, a traditional measuring tape or soft fish ruler must be used. This process is not only cumbersome but also inefficient. In the tense atmosphere of a competition, time is of the essence, and anglers need to quickly sort and record their catch. Frequently switching tools undoubtedly wastes a lot of time and reduces overall operational efficiency. The limited functionality of traditional fish sorting tools is one of the important reasons for this inefficiency. Most of these tools rely solely on weight comparison and lack length measurement capabilities. Anglers have to carry multiple tools, such as electronic scales and measuring tapes, when sorting their catch. During the process, they need to use both hands to grab and measure the fish, making it difficult for them to maintain stability and increasing the risk of injury to the fish as they struggle. Traditional fish sorting balances or weighing devices... The equipment has obvious design flaws. It generally lacks a length measurement function. In order to obtain the length information of the fish, anglers must carry an extra ruler. This not only increases the burden on the angler, but also requires the use of both hands, further increasing the difficulty and complexity of the operation. During the measurement process, because both hands need to be operated at the same time, it is difficult for the angler to effectively control the fish, which can easily lead to the fish slipping or getting injured. Lure fishing competitions usually follow the selection rule of "length meets the standard and weight takes priority". However, traditional methods have obvious shortcomings in implementing this rule. Since traditional tools cannot accurately measure the length and weight of the fish at the same time, anglers often have to measure the length first and then the weight, or only measure one of the indicators. This may lead to "long but light" fish being mistakenly caught, while fish that truly meet the requirements of the rules are missed, which seriously affects the fairness of the competition and the accuracy of the data. Utility Model Content

[0004] The purpose of this invention is to provide a fish sieve balance to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fish-sifting balance includes:

[0007] The balance ruler is provided with a scale for length measurement. The balance ruler has symmetrical hanging grooves on both sides and a round hole on one side.

[0008] The handle has a slot fixedly installed on the side of the handle near the balance ruler. A connecting rod is movably connected between the handle and the balance ruler. Both ends of the connecting rod are fitted with connecting rings. The connecting rings are fitted inside the round hole and the slot, and the connecting rings and the round hole and the slot form a loose fit.

[0009] A float is provided, with a hanging rope fixedly connected to its top end. The hanging rope is suspended inside the hanging groove. A connecting rope is fixedly connected to the end of the float away from the hanging rope. A counter is provided on the outside of the connecting rope. A fish mouth clamp is connected to the end of the connecting rope.

[0010] Preferably, the bottom of the handle has an arc-shaped structure, and the handle is made of closed-cell EVA foam material.

[0011] Preferably, the connecting rod is used to connect the balance ruler and the handle.

[0012] Preferably, the connecting rope is made of high-strength fiber woven and wrapped with silicone.

[0013] Preferably, the fish mouth clamp is used to clamp the fish mouth.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) This utility model integrates length measurement and weight comparison functions through integrated design. The high-precision scale set on the balance ruler allows anglers to measure the length of the fish without the need for an additional measuring tape. They only need to align the fish mouth with the "0" mark on the ruler and read the tail mark. This process is simple and quick, greatly saving operation time. When an angler catches a fish, they only need to clamp the fish mouth with the fish mouth clamp and lift the handle to obtain the weight comparison information of the two fish. Through accurate length measurement and intuitive weight comparison, the fairness of the competition results is ensured. Anglers can make reasonable selection decisions based on accurate fish catch information, avoiding unfairness caused by tool errors or improper operation.

[0016] (2) This utility model adopts an integrated structure of scale and suspension comparison. The angler can obtain the weight comparison data by lifting the handle with one hand. This operation method reduces the contact time between the angler and the fish and reduces the possibility of the fish struggling. The non-penetrating fish mouth clamp only acts on the external cartilage of the fish mouth and will not cause damage to the inside of the fish body. Compared with the traditional penetrating fish mouth clamp, the non-penetrating fish mouth clamp is gentler and can effectively reduce the damage to the fish body during the clamping process.

[0017] (3) The scale of this utility model can intuitively determine whether the fish body meets the length threshold, such as the 25cm standard. The angler only needs to align the fish mouth with the "0" mark on the scale to quickly determine whether the fish length meets the standard. At the same time, the weight difference can be quickly compared by the tilt angle of the scale. When two fish are suspended on both sides of the scale, the angler can intuitively understand the weight relationship between the two fish by observing the tilt of the scale. With the help of the float numbers, data marking and management can be realized. The angler can accurately record the length and weight information of each fish, avoiding the problem of "long but light" fish being mistakenly left because only the length is measured in the traditional method.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] Please see Figure 1 - Figure 4 As shown, the fish-sieve balance includes:

[0026] Balance ruler 1, the balance ruler 1 is provided with a scale 11, the scale 11 is used for length measurement, the balance ruler 1 has hanging grooves 12 symmetrically opened on both sides, and a round hole 13 is opened on one side of the balance ruler 1;

[0027] Handle 2, with a slot 21 fixedly installed on the side of handle 2 near balance ruler 1. A connecting rod 22 is movably connected between handle 2 and balance ruler 1. Connecting rings 23 are sleeved at both ends of the connecting rod 22. The connecting rings 23 are sleeved inside the round hole 13 and the slot 21, and the connecting rings 23 form a loose fit with the round hole 13 and the slot 21.

[0028] A float 3 is fixedly connected to a hanging rope 31 at its top. The hanging rope 31 is suspended inside the hanging groove 12. A connecting rope 32 is fixedly connected to the end of the float 3 away from the hanging rope 31. A counter 33 is set on the outside of the connecting rope 32. A fish mouth clip 34 is connected to the end of the connecting rope 32.

[0029] Specifically, the bottom of the handle 2 has an arc-shaped structure, the handle 2 is made of closed-cell EVA foam material, the connecting rod 22 is used to connect the balance ruler 1 and the handle 2, the connecting rope 32 is made of high-strength fiber woven and wrapped with silicone, and the fish mouth clamp 34 is used to clamp the fish mouth.

[0030] As shown above, the scale 11 on the balance ruler 1 is used to measure the length of the fish, the hanging groove 12 is used to hang the hanging rope 31, and the round hole 13 is used to connect the connecting ring 23 to the handle 2. The handle 2 has an arc-shaped grip design, a non-slip texture on the surface, and a floating function. It is connected to the balance ruler 1 through the groove 21 and the connecting ring 23. The connecting rod 22 is connected to the balance ruler 1 and the handle 2 through the connecting rings 23 at both ends, allowing the ruler to rotate freely to truly reflect the torque difference of weight comparison. The float 3 is made of high-density soft material. Made of floating material, the surface is marked with colors and numbers to distinguish groups and capture order. The counter 33 is manual, and counting can be done by turning a knob on one side. The fish mouth clamp 34 is a non-through clamp with a nylon body and soft teeth to prevent slipping and protect the fish. The length is measured by reading the tail scale value by aligning the fish mouth with the "0" mark on the scale. The weight is determined by the tilt angle caused by the difference in gravitational torque when two fish are suspended on the scale. The data is marked and managed with the float 3, which meets the selection rule of "length meets the standard and weight is given priority" in competitive competitions.

[0031] When using the balance ruler 1, place it horizontally on a flat surface, align the fish's mouth with the "0" mark on the balance ruler 1, and read the mark corresponding to the fish's tail to obtain the fish's length. Clamp the two fish with the fish mouth clamp 34 and suspend them on both sides of the balance ruler 1. By observing the tilt angle of the balance ruler 1, determine the weight of the two fish. At the same time, distinguish the groups and capture order according to the color and number markings on the surface of the float 3, and use the counter 33 to count, realize data marking and management. According to the competition rule of "length meets the standard and weight takes priority", the angler judges whether the fish body meets the length threshold by using the mark 11 on the balance ruler 1, and then compares the weight difference by combining the tilt angle of the balance ruler 1 to select the fish that meet the requirements.

[0032] In this embodiment, the balance ruler 1 is made of carbon fiber. Carbon fiber has the characteristics of high strength and low density, which makes the balance ruler 1 lightweight while ensuring sufficient strength, making it easy for anglers to carry and operate. The connecting ring 23 is made of corrosion-resistant titanium alloy. Titanium alloy has excellent corrosion resistance and can be used in freshwater environments for a long time without rusting, extending the service life of the connecting ring 23. The float 3 is colored according to the competition standard color, which makes it easy for anglers to quickly identify and distinguish the catches of different groups and catch order during the competition. The connecting rope 32 is made of 16 strands of UHMWPE (ultra-high molecular weight polyethylene) with a diameter of 2.4mm and wrapped with silicone. UHMWPE has the characteristics of high strength and low elongation. The inherent properties of the connecting rope 32 give it excellent tensile strength, enabling it to withstand the weight of the fish mouth clamp 34 and the fish. The silicone layer increases the flexibility and abrasion resistance of the connecting rope 32, while also providing a good feel for easy handling by the angler. The fish mouth clamp 34 is a non-penetrating clamp with a nylon body and soft teeth at the clamp opening. The nylon material has high strength and abrasion resistance, making it suitable for the needs of freshwater lure fishing competitions. The non-penetrating design avoids damage to the inside of the fish, while the soft teeth increase the stability of the clamp and reduce the risk of injury from the fish struggling. The standard competition version of the fish sieve balance in this embodiment is mainly used in freshwater lure fishing competitions, where anglers need to quickly and accurately sieve and record the catch.

[0033] Example 2:

[0034] This enhanced fish-screening balance, as described in this embodiment, is primarily designed for sea fishing environments. In sea fishing, the catches are typically large and heavy, and the marine environment demands high corrosion resistance from tools. The balance ruler 1 is made of 6061 aluminum alloy with a hard anodized surface, 25μm thick. 6061 aluminum alloy possesses excellent strength and corrosion resistance, allowing it to withstand the harshness of the marine environment. The hard anodizing further enhances the surface hardness and wear resistance, extending the lifespan of the balance ruler 1. The ruler features high-precision graduations 11, including millimeters and inches (0-16 inches), conforming to international competition standards and facilitating use in various competitions. The handle 2 incorporates a 6061 aluminum alloy counterweight, increasing grip stability. In sea fishing environments, due to factors such as waves, anglers require a more stable grip. The counterweight makes the handle 2 more balanced, reducing swaying and improving operational accuracy. The float 3 has a density of 0.7g / cm³. 3The float 3 is designed to adapt to the buoyancy of seawater, allowing it to float better and ensuring the balance of the balance scale 1. The color of the float 3 can be selected according to actual needs for easy identification by anglers. The outer layer of the connecting rope 32 is coated with PTFE (polytetrafluoroethylene), which has excellent anti-ultraviolet aging properties. In the sea fishing environment, the sunlight is strong, and ultraviolet rays can easily damage the connecting rope 32. The PTFE coating can effectively block ultraviolet rays and extend the service life of the connecting rope 32. The main body of the fish mouth clip 34 is made of 316 stainless steel. 316 stainless steel has excellent corrosion resistance and can be used in the seawater environment for a long time without rusting, ensuring the reliability and durability of the fish mouth clip 34. The fish mouth clip 34 is also a non-through design with soft teeth in the clamp to reduce damage to the fish.
