Abstract
Description
Technical Field
[0001] This utility model relates to the field of lure accessories, specifically to a lead insert. Background Technology
[0002] Lure fishing primarily targets predatory fish in freshwater or saltwater using artificial lures. Its unique approach is often referred to as "water golf." When fishing for fish like largemouth bass, a common method involves using noodle worms (soft lures / artificial lures) with wacky or crank hooks. If necessary, a sinker is inserted into the noodle worm to increase its sinking speed. As the noodle worm sinks in the water, the rod tip needs to be jerked to stimulate the largemouth bass to bite. Traditional sinkers are bar-shaped with a sharp end and an anti-slip ring on the outer wall. The sharp end pierces the noodle worm (soft lure / artificial lure), increasing its weight and accelerating its drift in the water. The sinking speed also helps to increase the casting distance; however, in this fishing method, the wacky hook or crank hook is usually inserted into the middle of the noodle worm (soft bait / artificial bait), and when casting, the sinker can easily pull on the noodle worm (soft bait / artificial bait), causing damage or tearing at the hook point. When it falls, the weight difference at both ends of the noodle worm (soft bait / artificial bait) can cause it to hang vertically. Another baiting method is to insert the wacky hook or crank hook into the front head of the noodle worm (soft bait / artificial bait), but this method occupies the space for inserting the sinker, so it is difficult to achieve the purpose of both methods. Utility Model Content
[0003] Based on the above problems, the purpose of this utility model is to provide a lead sinker that can be adapted and fixed with wacky hooks or crank hooks, while allowing adjustment of the overall weight when inserted into a noodle worm (soft bait / artificial bait).
[0004] To address the above problems, the following technical solution is provided: a lead insert, including a plug rod, one end of which is provided with a tapered tip, and the other end is provided with a through hole / groove extending radially through the plug rod.
[0005] In the above structure, during use, the plug rod is inserted into the head or end of the noodle worm (soft bait / artificial bait) through the cone tip, while the wacky hook or crank hook passes through the through hole / groove so that the hook shank is positioned inside the through hole / groove. Then, the hook tip of the wacky hook or crank hook is inserted through the body of the noodle worm (soft bait / artificial bait) to hook the bait. This method can ensure the firmness of the sinker and the noodle worm (soft bait / artificial bait) installation, and can also ensure that the two will not interfere with each other during installation.
[0006] The present invention is further configured such that the outer wall of the plug rod is provided with a backstop, the backstop being in the forward direction when the cone tip is inserted into the noodle worm (soft bait / artificial bait) and in the reverse direction when it is pulled out, so as to prevent the noodle worm (soft bait / artificial bait) from coming out.
[0007] In the above structure, the anti-reverse component prevents the plug rod from coming out backward after being inserted into the noodle worm (soft bait / artificial bait).
[0008] The present invention is further configured such that the anti-retraction component is an outwardly convex ring or an inwardly concave groove; or a barb / thorn; and one or more are provided on the outer wall of the plug rod.
[0009] In the above structure, the anti-reverse component is preferably a barb / barb, which can improve the fixation strength with the noodle worm (soft bait / artificial bait).
[0010] The present invention is further configured such that when the anti-retraction member is an outwardly convex ring or an inwardly concave groove, a guide slope is provided on the side facing the cone tip.
[0011] The above structure aims to reduce insertion resistance while achieving a backlash prevention effect.
[0012] The present invention is further configured such that the anti-retraction member is located on both sides of the plug rod, that is, at the 3 o'clock position and the 9 o'clock position in the circumferential direction of its cross-section, and the anti-retraction member is provided in multiple units at intervals along the length direction of the plug rod.
[0013] In the above structure, since the retaining device is attached to the noodle worm (soft bait / artificial bait) at the 3 o'clock and 9 o'clock positions when it is fixed, disassembly will directly tear the internal structure of the noodle worm (soft bait / artificial bait) at the 3 o'clock and 9 o'clock positions. Therefore, by rotating the noodle worm (soft bait / artificial bait) 90 degrees, the torn parts during disassembly can be transferred to the 12 o'clock and 6 o'clock positions of the noodle worm (soft bait / artificial bait), ensuring that the 3 o'clock and 9 o'clock positions of the noodle worm (soft bait / artificial bait) remain intact when used again.
[0014] The present invention is further configured such that the anti-retraction component is provided in multiple ways, which are spaced apart along the length direction of the plug rod and staggered from each other.
[0015] The above structure can reduce the swelling effect of the anti-reverse component on the noodle worm (soft bait / artificial bait) on the same side of the plug rod.
[0016] The present invention is further configured such that the cross-section of the plug rod is circular, elliptical, or polygonal.
[0017] In the above structure, the cross-section of the plug rod is preferably circular.
[0018] The present invention is further configured such that the end of the plug rod away from the cone tip forms a handle, the handle is flat, and the through hole / groove penetrates through the thickness direction of the handle, that is, through the 12 o'clock direction to the 6 o'clock direction of the handle cross section.
[0019] In the above structure, the thickness of the shank is equal to the diameter of the connector rod; the through hole / groove extends through the thickness of the shank to ensure that the hook shank can pass through smoothly.
[0020] The present invention is further configured such that the long diameter direction of the through hole / groove is oriented towards the axial direction of the plug rod.
[0021] In the above structure, when a fish bites, the connecting rod creates a swinging space, causing the hook point to be exposed.
[0022] The present invention is further configured such that the plug rod is integrally made of lead, lead alloy or tungsten steel.
[0023] In the above structure, the plug rod, handle, anti-reverse component, and through hole / slot are directly integrally formed by casting.
[0024] The beneficial effects of this utility model are as follows: When in use, the plug rod is inserted into the head or end of the noodle worm (soft bait / artificial bait) through the cone tip, and at the same time, the wacky hook or crank hook passes through the through hole / groove so that the hook shank is located in the through hole / groove. Then, the hook tip of the wacky hook or crank hook passes through the body of the noodle worm (soft bait / artificial bait) to achieve baiting. This method can ensure the firmness of the lead weight and the noodle worm (soft bait / artificial bait) installation, and can also ensure that the two will not interfere with each other during installation.
