Description

Technical Field

[0001] This application relates to the field of slingshot fishing, and in particular to a slingshot fish dart release device. Background Technology

[0002] A slingshot harpoon launcher is an auxiliary tool specifically designed for fishing with a slingshot. It is typically mounted on a slingshot to launch the harpoon more accurately, thereby increasing the success rate of catching fish.

[0003] Existing slingshot fish dart release devices utilize a one-piece hook with a spring at its bottom. In use, pressing the top of the hook compresses the spring, hooking the dart line or slingshot bowstring onto it. Releasing the hook locks the dart line or bowstring in place. Pulling back a certain distance releases the lock by pressing the hook again, allowing for rapid firing. However, the spring's elasticity gradually weakens with repeated use, reducing the locking and releasing force. This leads to changes in the initial velocity and direction of the dart, affecting accuracy and stability. The existing technology requires opening the release device's bottom cover and using external tools to adjust the internal adjusting bolts or replace the spring, a cumbersome process that consumes considerable time and effort. To address these issues, a new slingshot fish dart release device is proposed.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a slingshot fish dart release device. (See also...) Figure 1-4A slingshot harpoon fishing release device includes a release device housing 1, with a threaded hole 2 and a bowstring hook 3 on the housing 1. A pressing post 6 is slidably disposed inside the housing 1, with a positioning groove 7 on the pressing post 6. A positioning pin 8 is threaded into the threaded hole 2 to maintain the stability of the positioning pin 8. One end of the positioning pin 8 passes through the positioning groove 7 and abuts against the inner wall of the release device housing 1. The cooperation between the positioning groove 7 and the positioning pin 8 limits the sliding of the pressing post 6 within the release device housing 1. The pressing post 6 has a hook 9 for hooking the harpoon's tail line or bowstring. The hook 9 is integrally formed with the pressing post 6, reducing structural weaknesses caused by welding, riveting, or other connection methods, making the overall structure more robust and stable. A detachable elastic component is slidably disposed at the bottom of the pressing post 6, including a slider 10, a sliding plate 11, a slider 2 12, an adjusting plate 13, and a spring 14. A guide groove 4 is provided on the inner wall of the release device housing 1, through which slider 10 and slider 2 12 slide. Within the guide groove 4, the adjusting plate 13 is fixed to the second slider 12, and the sliding plate 11 is fixed to the first slider 10. The two ends of the spring 14 abut against the sliding plate 11 and the adjusting plate 13 respectively. The top of the sliding plate 11 abuts against the bottom of the pressing column 6. In use, hold the dispenser housing 1 and press the pressing column 6 downwards with your thumb until the top of the hook 9 is flush with the bottom surface of the bowstring opening 3. At this time, the pressing column 6 presses down on the sliding plate 11, causing the spring 14 to contract vertically downwards under the guidance of the guide groove 4, reducing lateral movement. The force generated vertically engages the harpoon's tail line or bowstring in the bowstring opening 3, making the initial speed and direction of the harpoon more stable during launch and improving shooting accuracy. Releasing the pressing post 6 resets the spring 14, causing the hook 9 to move upwards until it exceeds the top surface of the bowstring opening 3, thus locking the harpoon's tail line or bowstring. Pulling the release housing 1 backwards to the appropriate pulling distance and pressing the pressing post 6 again releases the lock on the harpoon's tail line or bowstring, thus enabling the fish-shooting action.

[0024] Reference Figure 1 , 2 The dispenser housing 1 is also equipped with an adjustment assembly for adjusting the spring force of the spring 14. The adjustment assembly includes a connecting rod 15, a bottom cover 16, and a knob 17. The bottom cover 16 is threaded to the bottom of the dispenser housing 1 to prevent external dust from entering the dispenser housing 1. The top end of the connecting rod 15 passes through the bottom cover 16 and rotates at the bottom of the slide plate 11. The bottom cover 16 provides stable support for the connecting rod 15. The adjustment plate 13 is threaded to the connecting rod 15. The knob 17 is fixed to the bottom end of the connecting rod 15. Turning the knob 17 causes the connecting rod 15 to rotate. Under the guidance of the guide groove 4, the adjustment plate 13 moves closer to the slide plate 11, thereby adjusting the pressure of the spring 14. Users can adjust the spring force by using the knob 17 without opening the dispenser housing 1, simplifying the adjustment process.

[0025] It should be noted that the surface of the connecting rod 15 that passes through the bottom cover 16 is smooth, and the part of the connecting rod 15 located between the bottom cover 16 and the slide plate 11 is threaded.

[0026] Reference Figure 2 , 3 The bottom of the inner wall of the dispenser housing 1 is provided with an internal thread 5. The bottom cover 16 is connected to the bottom of the dispenser housing 1 by the internal thread 5, which ensures a tight fit between the bottom cover 16 and the dispenser housing 1, effectively preventing moisture, dust and other impurities from entering the interior, and improving the sealing and waterproof performance of the dispenser housing 1.

[0027] Reference Figure 2 , 4 A limiting rod 18 is inserted into the guide groove 4. The top of the limiting rod 18 abuts against the bottom of the second slider 12 to limit the position of the second slider 12. A limiting washer 19 is fixed to the top of the limiting rod 18. The limiting washer 19 is located between the bottom cover 16 and the bottom surface of the dispenser housing 1. When the bottom cover 16 is threadedly connected to the bottom of the dispenser housing 1, the limiting washer 19 abuts against the bottom surface of the dispenser housing 1, and the bottom cover 16 abuts against the bottom surface of the limiting washer 19, forming a double limiting, which ensures the stable connection of the bottom cover 16. At the same time, the limiting washer 19 enhances the sealing effect between the bottom cover 16 and the dispenser housing 1, further improving the sealing and waterproof performance of the dispenser housing 1.

[0028] Reference Figure 1 The top of the pressing column 6 is provided with a pressure plate 20 to facilitate pressing the pressing column 6. The outer surface of the pressing column 6 and the inner wall of the dispenser housing 1 are both provided with circumferential grooves 21 for the rolling of the balls 22. The balls 22 roll in the grooves 21, which greatly reduces the friction between the pressing column 6 and the dispenser housing 1, making the up-and-down sliding of the pressing column 6 smoother. The grooves 21 ensure the precise guidance of the pressing column 6 during the sliding process, avoid lateral deviation or shaking, and improve the stability of the entire pressing column 6 movement.
