Abstract
Description
Technical Field
[0001] This utility model relates to the field of lead weight holder technology, and in particular to a novel lead weight holder for fishing. Background Technology
[0002] In fishing, the lead sinker is a key component of the fishing rig, and its performance has a significant impact on fishing results. Traditional lead sinkers have some unresolved issues in use, and the diversification of fishing scenarios also places higher demands on the functionality of lead sinkers.
[0003] When fishing in the wild, the bait and hook will sink slowly in the water due to the light weight of the sinker when cast into the water. Small fish often inhabit the upper and middle layers of the water, competing for the bait and reducing fishing efficiency. A heavy sinker method allows the bait to sink quickly to the bottom, avoiding interference from the small fish in the upper and middle layers and increasing the chances of catching bottom-dwelling fish. Furthermore, in flowing rivers, a high-sensitivity fishing setup can cause the hook, bait, sinker, and float to be swept away by the current. Therefore, a sinker suitable for heavy sinkers that maintain good signal transmission is essential for wild fishing. In commercial fishing ponds (paid fishing ponds), there are often many "recycled fish" (old, wary fish that have been caught and released back into the pond, such as grass carp and common carp). These fish are highly wary, and pulling the line upwards with traditional fishing methods may obstruct their mouths, especially since grass carp in commercial ponds tend to spit out the bait immediately after inhaling it, making them hesitant to take the bait.
[0004] Traditional lead sinker seats have a straight hole in the center. In heavy sinker bottom fishing, the sinker rests on the bottom for extended periods, with the float pulled upwards by the fishing line. Over time, the fishing line bends at the hole due to stress (e.g., a 90-degree bend or an L-shape). This can prevent the line from transmitting the signal to the float promptly when a fish takes the bait, affecting the angler's judgment of the bite. While some lead sinkers on the market now feature flared ends to address this signal transmission problem, these designs have new drawbacks. If the flare is too large, the line stopper can easily get stuck; if the flare is too small, the line protection is inadequate, failing to effectively prevent the line from creating a dead angle at the hole.
[0005] Using a lead sinker seat that allows the leader and hook to lie flat on the ground reduces interference from the fishing line on the fish's bite and ensures effective signal transmission, lowering the fish's wariness and thus increasing the success rate of fishing in commercial ponds. This requires the lead sinker seat to have characteristics adapted to this fishing method. Therefore, addressing the signal transmission problems of traditional lead sinkers and the needs of existing fishing scenarios, this new type of lead sinker seat aims to design a design that can prevent the fishing line from forming dead angles at the hole, ensure timely signal transmission, prevent the stopper from getting stuck, be suitable for heavy-weight bottom fishing, and also accommodate normal fishing methods. Its core lies in achieving a balance between line protection and preventing the stopper from getting stuck through a unique arc design and hole structure, thus meeting the performance requirements of the lead sinker seat in different fishing scenarios. Utility Model Content
[0006] The main purpose of this invention is to propose a new type of lead weight holder for fishing, which can effectively solve the problems in the background art.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a novel lead weight holder for fishing, comprising:
[0008] A lead-skin holder body, wherein a wire hole is formed along the length direction inside the lead-skin holder body;
[0009] The first shoulder is located at one end of the lead sheet body;
[0010] The second shoulder is located at the other end of the lead sheet body;
[0011] The second shoulder includes a shoulder portion and a connecting portion, which are connected by an arc transition. The shoulder portion and the connecting portion are provided with interconnected holes. A protrusion is provided on one side of the hole. The hole communicates with the line hole to form a continuous channel for the fishing line to pass through.
[0012] The inner wall of the hole is curved, which allows the fishing line to make a smooth transition in the channel and avoids forming dead angles such as 90° or L-shaped bends.
[0013] As a further description of the above technical solution, the first shoulder is an annular protrusion structure that surrounds the outer periphery of one end of the lead sheet body.
[0014] As a further description of the above technical solution, the arc transition connection between the shoulder and the connecting part is a circular arc transition or an elliptical arc transition.
[0015] As a further description of the above technical solution, the inner wall of the continuous channel is smooth, and the hole is a flat hole.
[0016] As a further description of the above technical solution, the shoulder is fixedly connected to the lead sheet body, and the connecting part and the shoulder form a stepped structure.
[0017] As a further description of the above technical solution, the lead sheet body, the first shoulder and the second shoulder are integrally injection molded structures.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] 1. Signal transmission is timely. Because the second shoulder of the new lead sinker uses an arc-shaped transition (circular or elliptical arc) between the shoulder and the connecting part, and the inner wall of the hole is arc-shaped, the fishing line can smoothly transition within the continuous channel, completely avoiding 90° or L-shaped dead angle bends. Compared to the signal transmission delay problem caused by fishing line bending in traditional straight-hole lead sinkers, this design allows the fishing line to instantly transmit the action to the float when the fish takes the bait, improving the angler's sensitivity to fish bites.
[0020] 2. Flat Hole and Stepped Structure: The hole adopts a flat design with a smooth inner wall. Combined with the stepped structure of the connecting part and the shoulder, it can reduce friction damage to the fishing line (line protection effect) and prevent the stopper from getting stuck due to the excessively wide channel. Compared with the traditional flared sinker seat, which requires a compromise between "line protection effect" and "prevention of stopper jamming" (large flared mouth protects the line but is prone to stopper jamming, while small flared mouth is the opposite), this design achieves dual functions without enlarging the hole through an asymmetrical stepped structure and flat hole. It is particularly suitable for heavy sinker bottom fishing (such as fishing for bottom fish in the wild, where the river water is flowing and resists the current) and fishing for wary fish in commercial ponds: When the heavy sinker lies on the bottom, the arc-shaped channel avoids long-term bending and wear of the fishing line, improving signal transmission efficiency; in commercial pond scenarios, the stepped second shoulder allows the leader to lie naturally on the bottom, reducing the obstruction of the fishing line to the fish's mouth and reducing the wariness of the fish that have been caught before.

[0026] To make the technical means, creative features, and objectives of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments.
[0027] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0029] Please see Figure 1-4 This utility model provides a technical solution: a novel lead weight holder for fishing, comprising: a lead weight holder body 1, a first shoulder 3 and a second shoulder 4. The lead weight holder body 1, the first shoulder 3 and the second shoulder 4 are integrally injection molded structures. A line hole 2 is provided in the lead weight holder body 1 along the length direction for threading fishing line. The first shoulder 3 is located at one end of the lead weight holder body 1 and is an annular protrusion structure that surrounds the outer periphery of one end of the lead weight holder body 1. The second shoulder 4 is located at the other end of the lead weight holder body 1.
[0030] The second shoulder 4 includes a shoulder portion 41 and a connecting portion 42, which are connected by an arc transition. The shoulder portion 41 and the connecting portion 42 have interconnected holes 43 inside. One side wall of the hole 43 is arc-shaped, allowing the fishing line to smoothly transition within the channel and avoiding 90° or L-shaped bends. The hole 43 is a flat hole and communicates with the line hole 2, forming a continuous channel for the fishing line to pass through. The inner wall of the continuous channel is smooth. A protrusion 44 is provided on one side of the hole 43. The protrusion 44 is an arc-shaped protrusion and is located at the other end of the hole 43 away from the arc-shaped inner wall. The arc directions of the two are the same. When the fishing line is placed in the water, it will move closer to the arc-shaped inner wall of the hole 43 due to the protrusion 44. The shoulder 41 is fixedly connected to the lead base body 1. The connecting part 42 and the shoulder 41 form a stepped structure. The arc transition between the shoulder 41 and the connecting part 42 is a circular arc transition or an elliptical arc transition.
[0031] To further explain, the shoulder 41 of the second shoulder 4 and the connecting part 42 are connected by a circular arc or elliptical arc, and the inner wall of the hole 43 is arranged in an arc shape, so that the fishing line forms a smooth transition in the continuous channel, avoiding 90° or L-shaped dead angle bends. When the fish bites the hook, the fishing line is pulled by the force and the float moves. Because the inner wall of the channel is smooth and the arc design is reasonable, the fishing line can transmit the action to the float in time, reducing the signal delay problem caused by the bending of the fishing line in the traditional straight hole lead seat, and improving the angler's sensitivity to the fish bite.
[0032] To further explain, the hole 43 adopts a flat design with a smooth inner wall. Combined with the stepped structure of the connecting part 42 and the shoulder part 41, it can reduce frictional damage between the fishing line and the lead weight, thus protecting the line. At the same time, the asymmetrical stepped structure can limit the range of motion of the bobber, preventing it from getting stuck in the hole. Compared with the traditional flared lead weight, which has to compromise between "line protection" and "preventing bobber from getting stuck", this design can achieve both functions simultaneously without enlarging the hole through structural innovation.
[0033] To further explain, in the scenario of heavy lead lying on the bottom, the lead seat body 1 lies on the bottom due to its own weight (the weight of the lead sheet wrapped on the lead seat 1), and the fishing line can slide freely in the arc-shaped channel, avoiding long-term bending and wear, while ensuring signal transmission efficiency; in the scenario of wary fish in black pits, the stepped second shoulder 4 makes the leader line lie on the bottom naturally, reducing the obstruction of the fishing line to the fish's mouth, reducing the wariness of the fish, and increasing the catch rate.
[0034] This is to clarify, such as Figure 3 As shown, this is a diagram illustrating the application of this lead weight seat in the heavy lead bottom fishing method. The lead weight seat is set between two space beans, and the distance between the two space beans should be greater than the overall length of the lead weight seat. When a fish bites the hook and pulls the fishing line, the lead weight seat body 1 lies still on the bottom due to its own weight, while the fishing line slides in the line hole 2, thereby moving the float to alert the angler.
[0035] It should be noted that this utility model is a new type of lead weight holder for fishing. Compared with existing new types of lead weight holders for fishing, this utility model avoids dead angles and bends in the fishing line through the arc transition connection and arc-shaped hole design, ensuring timely signal transmission. The flat hole and stepped structure take into account both the line protection effect and the function of preventing the space bead from getting stuck. It is suitable for heavy lead bottom fishing and fishing for slippery fish in black pits, improving fishing efficiency and experience.
[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
