Description

Technical Field

[0001] This utility model relates to the field of fishing gear technology, specifically a novel fish lock buckle. Background Technology

[0002] In fishing, a fish lock is a common tool used to secure live fish. Its main function is to pierce the gills or mouth of a fish after it has been caught and lock it in place, preventing the fish from escaping. The fish lock is then attached to a rope and lowered into the water to keep the fish alive.

[0003] Traditional fish-locking buckles are typically constructed from a single, bent steel wire, comprising two main parts: a fixed locking section and a movable piercing end. The movable piercing end penetrates the fish's gills or mouth bone and works in conjunction with the fixed locking section to achieve rapid opening and closing. The fixed locking section forms a vertical groove structure through the forward and backward bending of the steel wire, with a clearance area on the side away from the closed end of the groove. During locking, pressing the movable end causes it to elastically deform and slide into the groove from the clearance area, utilizing the wire's spring-loaded properties to achieve locking. This is exemplified by the fish-locking device described in announcement number CN 214629259 U.

[0004] However, this design has significant technical flaws: the groove can only constrain the forward and backward displacement of the movable end and the disengagement in the direction of the closed end, lacking effective restriction in the vertical direction. When encountering large fish struggling violently, the movable end is prone to plastic bending under vertical impact force, sliding down the groove and causing the fish to escape. To address these flaws, existing technologies employ outward bending of the movable end to enhance the locking effect. While this approach can increase the contact area to some extent, its bending resistance is limited by the material's elastic modulus. Furthermore, the bend formed by the outward bending can easily cause lacerations to the fish's oral cavity or gill tissue during puncture operations, affecting the fish's survival. Summary of the Invention

[0005] To address the problems existing in the prior art, this utility model provides a novel fish lock buckle that combines multi-directional limiting, high structural strength, and low damage characteristics.

[0006] The technical solution adopted by this utility model is as follows: A novel fish lock buckle includes a locking part, a movable end, and a clearance area for the movable end. The locking part is a snap-fit ​​structure formed by reciprocating bending to form a front-to-back extending groove. The closed end of the groove is located on the outside of the fish lock buckle, and the clearance area is located on the opposite side of the closed end of the groove. The movable end is provided with a Z-shaped bending part, which includes a front section, a middle section, and a rear section connected in sequence. The middle section passes laterally through the groove, and the front section and the rear section are located on the front and rear sides of the groove, respectively, and form a front-to-back limiting fit with the groove wall.

[0007] Furthermore, the locking part and the movable end are integrally bent from a single metal wire.

[0008] Furthermore, the movable end is an arc-shaped segment that bends toward the yielding area.

[0009] Furthermore, the middle section of the Z-shaped bend forms a bending angle of 100-150° with the front and rear sections.

[0010] Furthermore, the end of the movable end is provided with a puncture tip.

[0011] The beneficial effects of this utility model are as follows: This utility model, through the cooperation of the front and rear extending grooves and the Z-shaped bending part, the middle section of the Z-shaped bending part passes through the groove laterally, and the contact surface between the side wall of the groove and the middle section forms a vertical constraint. The front and rear sections of the Z-shaped bending part abut against the front and rear side walls of the groove respectively, realizing bidirectional front and rear limiting and forming a three-dimensional locking mechanism, which greatly improves the tensile strength. The bending range of the Z-shaped bending part is small, which ensures smooth puncture action and reduces secondary damage to the fish during puncture. Attached Figure Description

[0015] To facilitate understanding of this utility model, it will be described more comprehensively and in detail below with reference to the accompanying drawings and preferred embodiments. However, the scope of protection of this utility model is not limited to the following specific embodiments.

[0016] like Figures 1-3 As shown, this embodiment provides a novel fish-locking buckle, including a locking part 1, a movable end 2, and a clearance area 4 for the movable end 2. The locking part 1 is a snap-fit ​​structure formed by reciprocating bending to form a front-to-back extending groove 1a. The closed end of the groove 1a is located on the outside of the fish-locking buckle, and the clearance area 4 is located on the opposite side of the closed end of the groove 1a. The movable end 2 is provided with a Z-shaped bending part 3, which includes a front section 3a, a middle section 3b, and a rear section 3c connected in sequence. The middle section 3b passes laterally through the groove 1a. The front section 3a and the rear section 3c are located on the front and rear sides of the groove 1a, respectively, and form a front-to-back limiting fit with the wall of the groove 1a. The Z-shaped bending part 3 and the groove 1a generate a self-locking effect through an interference fit.

[0017] In use, the movable end 2 is first passed through the fish gills or mouth. Then, the angler presses the movable end 2 with their fingers to cause it to elastically deform towards the relief area 4, and slides it into the groove 1a from the opening end of the groove 1a. The locking is achieved by utilizing the spring-loaded properties of the steel wire. The middle section 3b of the Z-shaped bend passes laterally through the groove 1a. The contact surface between the side wall of the groove 1a and the middle section 3b forms a vertical constraint. The front section 3a and the rear section 3c of the Z-shaped bend abut against the front and rear side walls of the groove 1a respectively, achieving bidirectional front and rear limiting and forming a three-dimensional locking mechanism.

[0018] In this embodiment, the locking part 1 and the movable end 2 are integrally bent from a single steel wire.

[0019] In this embodiment, the movable end 2 is an arc-shaped segment that bends toward the clearance area 4. This design reduces the unlocking force compared to the traditional structure, allowing the movable end to be opened and closed with a single finger pressure.

[0020] In this embodiment, the middle section 3b of the Z-shaped bend 3 forms a bending angle of 100-150° with the front section 3a and the rear section 3c. The Z-shaped bend uses a gentle transition bending angle to reduce tearing damage to the gills and oral cavity tissues during puncture.

[0021] In order to facilitate piercing the fish mouth, in this embodiment, the end of the movable end 2 is provided with a piercing tip.

[0022] With the aid of the teachings present in the foregoing description and related drawings, those skilled in the art will conceive of many modifications and other embodiments of the present invention. Therefore, it is to be understood that the present invention is not limited to the specific embodiments disclosed, and modifications and other embodiments are considered to be included within the scope of the appended claims. Although specific terms are used herein, they are used in a general and descriptive sense only and are not intended to be limiting.
