Description

Technical Field

[0001] This utility model relates to the field of multi-joint biomimetic fish bait, and more specifically, this utility model relates to an elastic connection structure for multi-joint biomimetic fish bait. Background Technology

[0002] Multi-joint biomimetic bait is a fishing tool that mimics the form and movement of aquatic organisms. Its core feature is the design of multiple movable joints, which allows the bait to exhibit more realistic swimming, tail wagging, and curling movements in the water, thereby attracting fish to attack. These baits are usually composed of multiple segments such as head, body, and tail, which are connected by joint structures. The range of motion and flexibility of the joints directly affect the biomimetic effect of the bait. Multi-joint biomimetic bait imitates the movement trajectory of real organisms through the swinging and twisting movements of the joints, such as the S-shaped swaying of fish or the sudden jumping of shrimp. Each joint can move independently or in coordination, achieving multi-angle and multi-directional movement combinations, enhancing its attractiveness to different types of fish.

[0003] Currently, some multi-jointed bionic fish baits on the market adopt an integrated molding structure, that is, the joints and each segment are fixed by injection molding or bonding through a mold to form a non-removable whole. This design faces the following core problems during fishing: local damage will lead to the scrapping of the whole. During use, the fish bait may suffer from local joint breakage, wear or loss of elasticity due to fish biting, hook snagging on the bottom, collision with reefs, etc. For example, the tail joint may crack due to frequent swinging, the elastic material of the torso joint may age and lose its deformation ability, and the joint pin may wear and loosen, making it unable to maintain a normal range of motion. Since the whole structure is not disassembled, even if only one joint is damaged, the entire fish bait must be discarded, resulting in waste of resources and increased use costs.

[0004] Therefore, an elastic connection structure for a multi-jointed biomimetic fish bait is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an elastic connection structure for a multi-joint biomimetic fish bait to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an elastic connection structure for a multi-jointed bionic fish bait, comprising a bionic fish head bait, a first bionic fish body bait on one side of the bionic fish head bait, a second bionic fish body bait on one side of the first bionic fish body bait, and a bionic fish tail bait on one side of the second bionic fish body bait. A connecting piece is hinged to one side of the first bionic fish body bait via a pin, and a connecting groove is formed on one side of the second bionic fish body bait. One end of the connecting piece extends into the interior of the connecting groove.

[0010] Preferably, the outer surfaces of the bionic fish head bait, the first bionic fish body bait, the second bionic fish body bait, and the bionic fish tail bait are all coated with a bionic coating. The bionic coating is made of a waterproof and wear-resistant material, and the outer surface of the bionic coating is provided with a reflective layer resembling fish scales.

[0011] Preferably, the outer surface of the bionic fish head bait has two bionic fish eyes fixedly connected, and the outer surface of the first bionic fish body bait has a connecting ring fixedly connected.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] Compared with existing technologies, the elastic connection structure of this multi-joint bionic fish bait, through a detachable elastic connection structure, such as the first bionic fish body bait component and the second bionic fish body bait component being connected by a combination of components such as connecting plates, connecting grooves, and sliding blocks, allows the damaged part to be disassembled and replaced simply by pulling the round button, without having to discard the entire bait, thus greatly extending the lifespan of the bait, reducing the usage cost for fishing enthusiasts, and reducing resource waste.

Example

[0022] As attached Figures 1-5 The diagram illustrates an elastic connection structure for a multi-jointed biomimetic fish bait, comprising a biomimetic fish head bait 1, a first biomimetic fish body bait 2 on one side of the biomimetic fish head bait 1, a second biomimetic fish body bait 3 on one side of the first biomimetic fish body bait 2, and a biomimetic fish tail bait 4 on one side of the second biomimetic fish body bait 3. A connecting piece 6 is hinged to one side of the first biomimetic fish body bait 2 via a pin 5. A connecting groove 7 is formed on one side of the second biomimetic fish body bait 3, with one end of the connecting piece 6 extending into the interior of the connecting groove 7. A fixing cover is fixedly connected to one side of the second biomimetic fish body bait 3. 8. A spring 18 is fixedly connected to the inner wall of the fixed cover 8. A sliding plate 10 is fixedly connected to one end of the spring 18. A sliding block 12 is fixedly connected to one side of the sliding plate 10. A snap-fit ​​groove 11 is opened on one side of the connecting piece 6. The connection between the bionic fish head bait 1 and the first bionic fish body bait 2, and between the second bionic fish body bait 3 and the bionic fish tail bait 4, are all connected by the connection method between the first bionic fish body bait 2 and the second bionic fish body bait 3. Fish hook assemblies 9 are fixedly connected to the bottom surface of the first bionic fish body bait 2 and the bottom surface of the bionic fish tail bait 4.

[0023] As can be seen from the above description, this utility model has the following beneficial effects: the connecting piece 6 is hinged to the first bionic fish body bait 2 through the pin 5, and can be inserted into the connecting groove 7 of the second bionic fish body bait 3, serving as a bridge between components. With the cooperation of the sliding block 12 and the locking groove 11, the stability and flexibility of the connection are ensured, allowing the joints of the bait to swing naturally. The sliding block 12 is locked into the locking groove 11 under the action of the spring 18, which can achieve a stable connection between components. In addition, by pulling the circular button 15, the first bionic fish body bait 2 and the second bionic fish body bait 3 can be disassembled, which can complete the quick disassembly and replacement of damaged components. The operation is simple and convenient. Example

[0024] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below, with reference to the specific working method described in detail:

[0025] like Figures 1-5As shown, in a preferred embodiment, a circular hole 14 is provided on one side of the fixing cover 8, and a circular rod 13 is fixedly connected to one side of the sliding plate 10. One end of the circular rod 13 passes through the circular hole 14 and extends to the outside of the circular hole 14. A circular button 15 is fixedly connected to one end of the circular rod 13. The circular button 15 is located outside the fixing cover 8, and anti-slip stripes are provided on the outer surface of the circular button 15. One end of the sliding block 12 extends into the interior of the locking groove 11, and the outer surface of the sliding block 12 contacts the inner wall of the locking groove 11. Furthermore, the fixing cover 8 serves as the interior part... The component provides protection and installation space. The circular hole 14 facilitates the passage of the circular rod 13. The anti-slip stripes on the circular button 15 make it easy for the user to grip. By pulling the circular button 15, the circular rod 13 and the sliding plate 10 are driven to control the sliding block 12. The spring 18 provides elastic force. When the sliding block 12 is aligned with the locking groove 11, the spring 18 pushes the sliding plate 10 and the sliding block 12, which enables the sliding block 12 to be locked into the locking groove 11, realizing a stable connection between the first bionic fish body bait 2 and the second bionic fish body bait 3, etc., and also facilitating the disassembly and replacement of damaged parts.

[0026] like Figures 1-5 As shown, in a preferred embodiment, a fishhook assembly 9 includes a connecting shaft 901. A threaded ring 902 is fixedly connected to the outer surface of the connecting shaft 901. A threaded connecting sleeve 903 is threadedly connected to the outer surface of the threaded ring 902. A threaded reinforcing sleeve 905 is fitted onto the outer surface of the connecting shaft 901. The inner ring of the threaded reinforcing sleeve 905 is threadedly connected to the outer surface of the threaded connecting sleeve 903. A fishhook pendant 904 is fixedly connected to the bottom surface of the threaded connecting sleeve 903. The initial fixation of the fishhook pendant 904 is achieved through the threaded connection between the threaded ring 902 and the threaded connecting sleeve 903. The threaded reinforcing sleeve 905 further reinforces the connection, preventing the threaded connecting sleeve 903 from loosening, ensuring that the fishhook pendant 904 is stable and reliable during fishing. Even if the fish struggles vigorously, it is not easy to fall off, thus improving the success rate of fishing. The outer surface of the bionic fish head bait 1, the outer surface of the first bionic fish body bait 2, and the second bionic fish head bait 904 are also shown. Both the outer surfaces of the live fish body bait 3 and the bionic fish tail bait 4 are coated with a bionic coating 17, which is made of waterproof and wear-resistant material. The outer surface of the bionic coating 17 has a reflective layer that mimics fish scales. Two bionic fish eyes 19 are fixedly connected to the outer surface of the bionic fish head bait 1. A connecting ring 16 is fixedly connected to the outer surface of the first bionic fish body bait 2. Furthermore, because the bionic coating 17 is made of waterproof and wear-resistant material and has a reflective layer that mimics fish scales on its outer surface, it can protect the bait body from water and external force corrosion, extending its service life. At the same time, the reflective layer that mimics fish scales can simulate the reflective effect of real fish in water, enhancing its attractiveness to fish. The bionic fish eyes 19 further enhance the realism of the bait, making it easier for fish to mistake the bait for real prey in the water, thus improving the fish-attracting effect. The connecting ring 16 makes it easy to connect the bait to the fishing line, making it convenient for anglers to use and control the bait.

[0027] The working process of this utility model is as follows:

[0028] In later use, the elastic connection structure of this multi-joint bionic fish bait first inserts the connecting piece 6 of the first bionic fish body bait 2 into the connecting groove 7 of the second bionic fish body bait 3. Then, the circular rod 13, sliding plate 10 and sliding block 12 are pulled by the circular button 15. Next, the connecting piece 6 continues to be inserted into the connecting groove 7. Then, after the sliding block 12 is aligned with the locking groove 11, the circular button 15 is released, so that the sliding block 12 can be locked into the locking groove 11 of the connecting piece 6 under the action of the spring 18, thus realizing a stable connection between the first bionic fish body bait 2 and the second bionic fish body bait 3. Similarly, the bionic fish head bait 1, the first bionic fish body bait 2, the second bionic fish body bait 3 and the bionic fish tail bait 4 are also connected by this connection structure.

[0029] If a part is damaged, such as the first bionic fish body bait 2 or the second bionic fish body bait 3, the circular button 15 can be pulled to drive the circular rod 13 and the sliding plate 10 to compress the spring 18, causing the sliding block 12 to disengage from the locking groove 11, thereby pulling the connecting piece 6 out of the connecting groove 7. The damaged part can be disassembled and replaced using the above connection method to avoid the entire part being scrapped. This is the working process and working principle of the device.

[0030] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
