Description

Technical Field

[0001] This utility model is applied to fishing and relates to fishing gear and supplies, specifically a lure that uses a chain structure made of interlocking links. Background Technology

[0002] For predatory fish, lure fishing is the most common method. By pulling the fishing line, the lure mimics the swimming motions of small fish, shrimp, or other small animals in the water, attracting predatory fish to attack. The hook on the lure then catches the predator. Most lures are made of materials such as silicone, resin, and plastic. To attract predatory fish, some lures have added light-emitting components. Because these materials are relatively weak, the hook is usually placed at the line swivel at the head of the lure. To increase the strength of the lure, the hook is placed at the tail end. Metal lures are often made using electroplating or chemical plating, wire drawing processes, or PVD vacuum coating to achieve a bright metallic luster or mimic the colors of the natural environment, thus attracting predatory fish.

[0003] This application utilizes the flexibility of a metal chain to mimic the swimming motion of small or sick fish, thereby attracting predatory fish. The metal chain is formed by interlocking links, resulting in a long chain that is both aesthetically pleasing and highly flexible. CN215957867U describes a novel lure fishing tackle where a chain is positioned inside the fish's body, connecting a front link to a rear hook. This chain structure is not the metal chain structure described in this application; it merely serves a high-strength connecting function. No published patents using metal chain structures for lure manufacturing were found; this application provides a new product form for lures. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a metal chain structure lure, in which the flexibility of the chain structure simulates the swimming of small animals or sick fish, thus becoming a new type of lure product.

[0005] The technical solution adopted by this utility model is as follows: This utility model metal link lure includes a chain body with interlocking links, a fishing ring at the front end of the chain body, and a tail hook at the tail end. The link can be a single link or multiple single links fixedly connected vertically. The single link is square, circular, or elliptical, and consists of four corners and four edges. The four corners have a groove and protrusion structure, i.e., the opposite side of the groove is a protrusion, and the opposite side of the protrusion is a groove. The four edges are inclined, with the inclination direction of the edges at the interlocking points of the single links being opposite. The grooves between the two interlocking single links interlock, with the protrusion exposed; the groove is formed by a bottom plane and a side plane, the bottom plane fitting, and the side plane contacting the outer surface of the edge. The hollow space of the single link corresponds to the size of the edge.

[0006] Preferably, the fixed connection position of the multi-ring chain is at the protrusion of the upper and lower adjacent single rings, and a hollow opening is formed between the grooves of the upper and lower adjacent single rings. The hollow opening cooperates with the protrusion of the fixed connection to form a fastening connection.

[0007] Preferably, the width of the hollow space is the diameter of the ring edge, and the length is two ring edge diameters, restricting the bending of the chain while allowing it to swing. The bottom plane and side plane are perpendicular, the groove is a right-angled groove, and the outer surface of the ring edge is set as a planar end face, with adjacent single rings contacting each other using the planar end face. This further limits the bending of the chain.

[0008] Preferably, the chain links are fixedly connected to the sides of the display pieces, and the display pieces are combined to form the outline of a fish, and the swaying of the lure creates the movement of the small fish.

[0009] Preferably, the display panel is equipped with a side hook to increase the success rate of fishing.

[0010] Preferably, the adjacent panels are in contact with each other by an arc, which helps to limit the flexibility of the chain.

[0011] Preferably, to increase the attraction of light to predatory fish, the outer surface of the lure's links and display piece is treated with iridescent colors.

[0012] The beneficial effects of this invention are: the metal chain connection provides high strength and prevents chain breakage; the flexible chain allows the lure to sway like a small animal in the water; and the vibrant colors attract predatory fish, increasing the success rate of fishing.

[0024] This utility model of a metal chain has the following structural features: 1) High strength and resistance to breakage due to metal ring connection. 2) Planar chain shape. After the chain links are connected, the chain can be placed stably on a flat surface, and the top surface or vertex of each chain link is located on a plane or regular arc surface. The cross-sectional profile is square, circular, or elliptical. The side view shows a single chain or multiple chains, and the front view shows interlocking links. 3) Good flexibility. The gap between the chain links determines the bending of the metal chain. If the gap is large, the metal chain can be wound like a rope; if the gap is small, the bending radius of the metal chain is large, allowing it to wriggle like a small fish or earthworm. If there is no gap, theoretically it cannot bend, and in practice it is more like a sick fish.

[0025] The term "interlocking" refers to the interlocking connection of two single rings. The term "adjacent" is divided into vertical adjacency and horizontal adjacency. Vertical adjacency refers to the positional relationship between two single rings, while horizontal adjacency refers to the positional relationship between two chain links, where they are close to each other. "Interlocking" and "adjacent" are only used to indicate positional relationships. Example 1

[0026] Appendix Figure 1 This is a three-dimensional schematic diagram of the chain link structure in this embodiment. In this embodiment, the chain link is a single link, and its top view shows a square with rounded corners, as shown in the attached diagram. Figure 2 The enlarged view shows a partial section. The two opposite corners of the chain link are grooves 1, the two opposite corners are protrusions 2, and the four ring edges are inclined sides connecting grooves 1 and protrusions 2. (Attached...) Figure 1 If the chain links are flipped over, the structure remains the same. That is, the two diagonal chain corners have the same structure: a groove and a protrusion. The opposite side of the groove is a protrusion, and the opposite side of the protrusion is a groove. The ring edge is an inclined structure that transitions from a groove to a protrusion, or vice versa.

[0027] Appendix Figure 2 This is a schematic diagram of the structure of this embodiment, provided by Appendix Figure 1The chain body 3 is formed by interlocking the links. A fishing ring 4 is attached to the front end of this chain body, and a tail hook 5 is attached to the rear end, forming a lure. The four edges of the links are divided into two interlocking edges (the two edges where the links interlock) and two side edges (the two edges where they are not interlocked). The interlocking edges of the links are inclined in opposite directions, ensuring that the grooves of the two interlocking links contact each other, with the protrusions exposed. This interlocking process forms a metal chain link. The protrusions of the links create an attachment... Figure 2 The front and back planes form a planar chain, and the two sides can form a straight line. When the chain is placed on the plane, it becomes a straight chain. The fishing ring 4 connects to the fishing line, and the tail hook 5 is used for fishing.

[0028] To limit the flexibility of the lure in this embodiment and prevent it from bending and deforming arbitrarily like a rope, the hollow space of the chain link in this embodiment corresponds to the size of the link edge. The cross-section of the link edge is circular, and the width of the hollow space of the chain link (see attached figure) Figure 2 The upper and lower dimensions of the chain link are the diameter of the link's edge, and the length of the hollow space is (see attached figure). Figure 2 The left and right dimensions of the chain links are the diameters of the two chain edges. Within this hollow space, the arc points of adjacent chain links contact each other, as shown in the attached diagram. Figure 2 As shown in the enlarged view. Thus, while the lure in this embodiment is flexible, its deformation range is limited; that is, it can be attached to... Figure 2 The lure bends in the forward and backward direction, but theoretically not in the up and down direction. However, due to the weight of the metal chain and manufacturing deviations in the grooves, a small-scale bend, i.e., a large-diameter bend, may occur. When the fishing line is dragged horizontally in the water, the lure can be made to swing left and right using the water resistance, like a small animal swimming. If dragged at an angle, it resembles a sick fish, making it more attractive to predatory fish.

[0029] It should be noted that in water, to avoid the effects of gravity and maintain the lure's near-straight shape, the groove should ideally be designed as a right-angled groove, as shown in the attached image. Figure 1 As shown, the bottom surface of the groove is flat, and the two sides are perpendicular to the bottom surface. When the grooves of the fastening chain links are engaged, the engaging grooves intersect, the flat bottom surfaces contact each other, and the side surfaces contact the outer surface of the ring edge. In this way, the shape of the grooves can be used to directly restrict the chain's movement. Figure 2 The lure can only move vertically and oscillate in the forward and backward direction, keeping it in a straight line. In other words, the vertical movement is limited by the sides of the groove and the outer surface of the ring, while the contact and slight separation of the bottom surface allow for forward and backward oscillation. Thus, when dragging this lure in the water, its oscillation resembles the movement of an earthworm or small snake, making it more attractive to predatory fish. Example 2

[0030] In Example 1, the adjacent chain links make arc-shaped contact points, and their flexible oscillation is constrained by manufacturing deviations, which poses difficulties for manufacturing precision or increases manufacturing costs. This example directly replaces the arc-shaped contact surface of the fastening edge with a small plane, using planar contact to limit the flexibility caused by deviation space. The chain links are shown in the attached diagram. Figure 3 As shown, the arc contact point is changed to end face 8, that is, a planar end face 8 is set on the outer contact surface of the snap-fit ​​edge. The lure structure is shown in the attached figure. Figure 4 As shown, the planar contact between adjacent chain links is as follows. Figure 4 As shown in the enlarged view. In this way, the loop edge can retain an appropriate gap within the hollow space of the chain link, which facilitates the manufacture of the chain. Example 3

[0031] This embodiment is an improvement upon the two embodiments described above. In the two embodiments described above, the lure can simulate a slender, small animal, but its shape does not resemble a small fish. This embodiment is illustrated in the appendix. Figure 5 As shown, on the side of each chain link, display pieces 6 of different lengths are fixedly connected. The outer edges of the display pieces 6 combine to form the outline of a small fish, and its swaying is more like the movement of a small fish swimming.

[0032] The cross-section of exhibit 6 is shown in the attached image. Figure 6 As shown, the extended piece of the fastening chain link has an arc-shaped contact. This arc-shaped contact can achieve the following: Figure 5 The oscillation in both forward and backward directions, along with the line contact limiting its flexible deformation in both vertical and horizontal directions, makes the lure in this embodiment move more like a small fish in the water. The arc-shaped line contact auxiliary chain of the display piece is attached... Figure 5 The horizontal structure can also omit this contact structure, as shown in the attached... Figure 5 As shown, gaps are left between the display pieces, and the drooping pieces make the fish look more like a diseased fish.

[0033] Additionally, through holes can be added to different display pieces, and side hooks 7 can be installed in these through holes to increase the success rate of fishing. Example 4

[0034] The above embodiments all involve interlocking between single rings. The chain link in this embodiment is a double ring, as shown in the attached diagram. Figure 7 As shown, two single rings from Embodiment 1 are fixedly connected vertically (e.g., by pressure welding). The fixed connection is located at the protrusion 2 of the two single rings, i.e., the protrusions are fixed vertically to each other. The grooves of the two single rings are vertically opposite each other, forming a hollow opening. That is to say, the corresponding corners of the square double rings are either fixed by protrusions or have hollow openings. The structure of the chain is shown in the attached figure. Figure 8 As shown, the protrusions of the chain links are fixed and fit with the hollow opening. The interlocking grooves between the single links are still used for fastening, equivalent to the chain bodies in two embodiments 1 being fixedly connected at the corresponding protrusion positions. The lure has a fishing ring 4 at the front end of the chain and a tail hook 5 at the rear end.

[0035] Similarly, multiple single rings from Example 1 are fixedly connected vertically to form a multi-ring chain. (See attached image) Figure 9 This is a four-link chain, with the raised positions of adjacent single links fixedly connected to form a raised fixation. The groove positions of adjacent single links form hollow openings. The raised fixation of the interlocking links and the hollow openings cooperate to form the chain body, as shown in the attached diagram. Figure 10 As shown, this is equivalent to the four chains in Example 1 being fixedly connected at the corresponding protruding positions. The lure has a fishing ring 4 at the front end of the chain and a tail hook 5 at the rear end. Example 5

[0036] This embodiment is based on the above embodiment, but adds a surface iridescent treatment, that is, laser iridescent treatment is applied to the outer surface of the chain links and the display piece to attract the attention of predatory fish by reflecting light.

[0037] The principle behind laser-processed iridescent effects: Using an ultrashort pulse laser, parallel stripe-shaped etched structures at the nanoscale are created, a so-called grating structure. At different incident angles of light, an iridescent effect is produced because the light, during its propagation, enters the narrow etched slits, causing it to deviate from its straight-line propagation. This generates countless wavelets within the slits, which superimpose to create the iridescent visual effect. This laser iridescent processing technology is currently available.

[0038] It should be noted that: 1) The above illustration and description using a square chain link as an example can also be changed to an ellipse or circle, with the ring edge changed from a straight edge to an arc edge, while still using a raised and grooved structure, and the grooves of the interlocking chain links interlocking. 2) The outline of the cross-section of the lure chain in the above embodiment is square, but it can also be changed by using a rounded transition in the cross-sectional shape of the single ring, making the outline of the cross-section of the lure chain elliptical or circular. 3) The metal chain in this utility model can also be replaced by other materials with higher strength. The "metal" in the metal chain only indicates the high strength of the lure material, and is not limited to metal materials. 4) The opposite inclination direction of the ring edge at the interlocking point has two meanings: first, the two interlocking ring edges of a single ring at an adjacent interlocking position have opposite inclination directions; second, the two interlocking ring edges of two single rings at a single interlocking position have opposite inclination directions. These two meanings are actually the same, that is, one interlocking ring edge at the interlocking position is the other interlocking ring edge at the adjacent interlocking point of the interlocking single ring.

[0039] This invention utilizes a metal chain structure, employing a metal chain connection that provides high strength. The flexibility of the chain allows the lure to sway in the water like a small animal, and the outline of the display piece resembles a small fish swimming. The vibrant colors further attract the attention of predatory fish, increasing the success rate of fishing.
