Abstract
Description
Technical Field
[0001] This utility model relates to the field of fishing gear, and in particular to a stress-relief spring. Background Technology
[0002] In fishing, the fishing line needs to withstand the instantaneous impact and continuous tension after a fish is hooked. However, existing fishing lines have obvious defects. The fishing line is prone to breakage due to instantaneous tension. The tension generated when a large fish charges can easily exceed the limit strength of the fishing line. Relying solely on the rod's dragger is insufficient to fully buffer the tension, resulting in the fish getting away.
[0003] Existing fishing line stress relief devices need to be installed on the fishing rod and cannot be integrated into the fishing line, resulting in poor flexibility and failing to solve the problem of line stress deviation. Therefore, we propose a stress relief spring to solve the above problems. Summary of the Invention
[0004] The purpose of this invention is to provide a stress-relieving spring to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A stress-relieving spring includes a spring body, wherein a bent connecting joint is installed at both the top and bottom ends of the spring body, and a connecting component is connected to one end of each of the two bent connecting joints.
[0006] In a further embodiment, the two connecting components each include an upper pull rod and a lower pull rod, both of which are located within the inner ring of the spring body and are coaxially symmetrically distributed.
[0007] In a further embodiment, the bottom end of the upper pull rod is connected to one end of one of the bent connecting joints, the top end of the upper pull rod passes through the spring body and extends above the spring body, and the top end of the upper pull rod is connected to an upper winding ring.
[0008] In a further embodiment, the top end of the pull rod is connected to one end of another curved connecting joint, the bottom end of the pull rod passes through the spring body and extends below the spring body, and the bottom end of the pull rod is connected to a lower winding ring.
[0009] The upper and lower winding loops can be open or closed loops.
[0010] Compared with the prior art, the beneficial effects of this utility model are: This utility model is a force-relieving spring that directly buffers the instantaneous impact force of a fish through the elastic deformation of the spring body. With the axial guidance of the upper and lower pull rods, the tension is transmitted in a fixed direction, avoiding excessive local stress on the fishing line, reducing the breakage rate of the fishing line, and improving the success rate of playing the fish. At the same time, the coaxial and symmetrical distribution of the upper and lower pull rods limits the radial tilt of the spring body when it contracts, thereby preventing the fishing line from deviating or tangling. Especially when dealing with the rush of large fish, the fishing line always maintains a stable stress state. Attached Figure Description

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of 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.
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0018] Please see Figure 1-3 In this utility model, a stress-relieving spring includes a spring body 1. Both the top and bottom ends of the spring body 1 are equipped with bent connecting joints 2. One end of each of the two bent connecting joints 2 is connected to a connecting component 3. When fishing lines are connected in series, the upper winding ring 4 connects to the main line and the lower winding ring 6 connects to the sub-line. When a fish is hooked and pulls the fishing line, the spring body 1 contracts along the double pull rod to relieve the stress, thus solving the problems of easy breakage and force deviation of traditional fishing lines.
[0019] The two connecting components 3 include an upper pull rod 7 and a lower pull rod 5, respectively. Both the upper pull rod 7 and the lower pull rod 5 are located in the inner ring of the spring body 1. The upper pull rod 7 and the lower pull rod 5 are coaxially symmetrically distributed. Both the upper pull rod 7 and the lower pull rod 5 are solid stainless steel rods with a diameter slightly smaller than the inner ring diameter of the spring body 1. Their lengths are adapted to the natural length of the spring body 1. Both are located in the inner ring of the spring body 1 and can slide synchronously with the spring contraction. The upper pull rod 7 and the lower pull rod 5 are coaxially symmetrically distributed, and their axes coincide with the axis of the spring body 1, which limits the radial displacement of the spring body 1 when it contracts, ensures that the fishing line tension is transmitted axially, and avoids the fishing line from breaking due to uneven force.
[0020] The bottom end of the upper pull rod 7 is connected to one end of one of the bent connecting joints 2. The top end of the upper pull rod 7 passes through the spring body 1 and extends above the spring body 1. The top end of the upper pull rod 7 is connected to the upper winding ring 4. The top end of the upper pull rod 7 is connected to the upper winding ring 4 by welding. The upper winding ring 4 is a circular metal ring, which is fixed by welding after being bent from stainless steel wire. It is compatible with fishing line connectors and is used to connect the main line of the fishing rod for easy and quick assembly and disassembly.
[0021] The top of the pull rod 5 is connected to one end of another bent connecting joint 2. The bottom end of the pull rod 5 passes through the spring body 1 and extends to the bottom of the spring body 1. The bottom end of the pull rod 5 is connected to the lower winding ring 6. The bottom end of the pull rod 5 is connected to the lower winding ring 6 by welding. The structure and material of the lower winding ring 6 are completely the same as those of the upper winding ring 4. The inner diameter of the ring is adapted to the leader connector for connecting the fishing leader or the fishing hook, so as to realize the complete series connection of the spring and the fishing line. The upper winding ring 4 and the lower winding ring 6 can be open rings or closed rings.
[0022] The working principle of this utility model is as follows: This stress-relieving spring works by first connecting the upper winding coil 4 and the lower winding coil 6 in series between the main line and the leader line of the fishing rod, forming a force-bearing link. When a fish bites and pulls the leader line, the tension is transmitted to the lower pull rod 5 through the lower winding coil 6. At the same time, the main line transmits the tension to the upper pull rod 7 through the upper winding coil 4. This causes the spring body 1 to be subjected to axial tension and contract towards the center along the upper pull rod 7 and the lower pull rod 5. Then, the spring absorbs the instantaneous impact force of the fish during the deformation process, converting the tension into elastic potential energy, thus achieving stress relief. Finally, the upper pull rod 7 and the lower pull rod 5 limit the radial displacement of the spring, ensuring stable force on the fishing line and preventing impurities from entering through the protective corrugated tube. Ultimately, this achieves the purpose of preventing fishing line breakage and improving the success rate of playing fish.
