Description

Technical Field

[0001] This utility model relates to the field of fishing gear technology, specifically to a folding device for a landing net pole and a landing net. Background Technology

[0002] A landing net typically consists of a net, an iron ring, and a handle. When fish are near the surface, it's used to scoop them up. When fishing, especially with a rod and reel, after playing the fish until it's exhausted and its belly turns white, the angler can submerge the landing net (to prevent startling the fish), raise the rod, and drag the fish to the shore, then scoop it up with the net. Without a landing net, it's generally difficult to bring a large fish ashore with a rod and reel. A search reveals Chinese patent CN217089216. U discloses a foldable landing net, including a fixing component one, a fixing component two, a switch, a landing net rod one, a landing net rod two, a spring, an arc-shaped groove one, a plug component one, a limiting groove, a limiting movable area, an arc-shaped groove two, and a plug component two. The key feature is that the diameter of the arc-shaped groove one gradually increases from the outside to the inside of the fixing component one, and the diameter of the arc-shaped groove two gradually increases from the outside to the inside of the fixing component two. The landing net rod one includes a landing net section, a rotating section, and a limiting section. The landing net rod two also includes a landing net section, a rotating section, and a limiting section. The rotating section is positioned between the arc-shaped groove one and the arc-shaped groove two, and the rotating section cooperates with the limiting groove formed by the arc-shaped groove one and the arc-shaped groove two. The outer end of the rotating section is fixedly connected to the landing net section, and the inner end of the rotating section... The end is equipped with a limiting section. The landing net section is placed outside the fixing component one and fixing component two to form a fishing net connecting section. The limiting section extends from the inner end of the rotating section towards the switch. One end of the limiting section is fixedly connected to the rotating section, and the other end abuts against the switch, limiting and fixing the position of the landing net section with the fixing component one and fixing component two. When the switch is pressed down to squeeze the spring, the switch separates from the limiting section, the rotating section rotates 180° between the arc groove one and arc groove two, and the landing net section flips backward, realizing the folding of landing net rod one and landing net rod two. The shortcomings of the above patent are: firstly, when operating the above patent, one hand needs to press the switch backward, and the other hand needs to rotate landing net rod one and landing net rod two to realize the folding or reset of landing net rod one and landing net rod two. First, it cannot be operated with one hand, making it inconvenient to operate. Second, the aforementioned patent is designed to fold downwards during use, while the switch is on top. When the operator is catching fish, if they accidentally touch the switch, and there are fish in the net, the net switch will open, causing the net pole to fold downwards under the weight of the fish. This downward folding of the net pole will cause the fish to swim out from the top of the net pole, resulting in low efficiency in catching fish. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a folding device for a landing net pole and a landing net that is ingeniously designed, can be operated with one hand, folds smoothly, is structurally stable, and has high efficiency in catching fish.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A net-falling pole folding device includes a first net-falling pole, a second net-falling pole, a first fixing component, and a second fixing component. The device is characterized in that a flip-folding mechanism is provided between the first and second net-falling poles and the first and second fixing components. The flip-folding mechanism includes a press-drive component, a first limiting block, a second limiting block, and a connecting block. The first and second fixing components are equipped with the press-drive component. The first fixing component has limiting slots on its left and right sides, and the first and second limiting blocks on both sides are capable of simultaneously extending or retracting. The rear ends of the first and second net-collecting poles are respectively provided with plug-in blocks. The plug-in blocks have positioning grooves on the side facing the first fixing component. The first and second net-collecting poles are plugged into the first fixing component via the plug-in blocks and the limiting slots. The first and second limiting blocks are driven by the pressing drive component to rest on the positioning grooves to lock and fix the first and second net-collecting poles to the first and second fixing components. Alternatively, the first and second limiting blocks are driven by the pressing drive component to separate from the positioning grooves to achieve the flipping and folding of the first and second net-collecting poles relative to the first and second fixing components.

[0005] The pressing drive assembly of this utility model includes an adjusting rod, an adjusting button, an adjusting block one, an adjusting block two, and a spring. The fixing assembly one has an upper adjusting groove, within which an adjusting rod is positioned. The upper end of the adjusting rod is fixedly connected to the adjusting button, and the lower end is fixedly fitted with adjusting block one and adjusting block two at a distance from each other. The adjusting button and / or the adjusting rod are slidably connected to the inner wall of the upper adjusting groove. The fixing assembly one and fixing assembly two have corresponding lower adjusting grooves. The lower adjusting groove has a front guide limiting groove on its front side and a rear guide limiting groove on its rear side, both communicating with the lower adjusting groove. The front guide limiting groove is closed at its left end and open at its right end. The limiting block two is placed within the front guide limiting groove and slidably connected to the fixing assembly one. The left end of the limiting block two is connected to the left end of the inner wall of the front guide limiting groove via a spring. The right end of the limiting block two is a telescopic limiting end. The limiting block two has a front opening on the side facing the lower adjusting groove, and the right end of the rear guide limiting groove is closed. The left end is open. The limiting block one is placed in the rear guide limiting groove and slidably connected to the fixing component one. The right end of the limiting block one is connected to the right end of the inner wall of the rear guide limiting groove via a spring. The left end of the limiting block one is a telescopic limiting end. The side of the limiting block one facing the downward adjusting groove has a rear opening. The outer diameter of the left side of the adjusting block one gradually decreases from top to bottom. The left side of the adjusting block one abuts against the left side of the inner wall of the front opening of the limiting block two. The outer diameter of the right side of the adjusting block two gradually decreases from top to bottom. The right side of the adjusting block two abuts against the rear opening of the limiting block one. The right sides of the inner walls of the opening abut against each other, so that when the adjusting block moves upward, the spring drives the first limiting block to move to the left and the second limiting block to move to the right. The right end of the second limiting block rests on the positioning groove of the second net-collecting rod, and the left end of the first limiting block rests on the positioning groove of the first net-collecting rod, locking the first and second net-collecting rods to the first and second fixing components. When the adjusting block moves downward, the first limiting block moves to the right and the second limiting block moves to the left, both separating from the positioning groove. At this time, the first and second net-collecting rods can be folded.

[0006] The limiting slot of this utility model has an opening facing downwards, and the plug block has a slot with an opening facing upwards. The slot and the limiting slot are engaged and fixed so that the first net-collecting rod and the second net-collecting rod can be flipped and folded from bottom to top.

[0007] The upper end of the upper adjustment groove of this utility model is provided with a baffle. The baffle is fixedly connected to a fixing component. The inner diameter of the baffle is smaller than the outer diameter of the adjustment button, so as to limit the adjustment button by the baffle and prevent the adjustment button from falling out of the fixing component.

[0008] The second limiting block of this utility model has a right-inclined guide surface formed by its right end tilting downwards and to the left, and the first limiting block has a left-inclined guide surface formed by its left end tilting downwards and to the right, so that the connecting block can be inserted into the limiting slot through the right-inclined guide surface and the left-inclined guide surface.

[0009] The present invention provides rotating sections on the first and second net-collecting poles, which are fixedly connected to either the first or second net-collecting pole. The first and second fixing components are fastened together and fixedly connected by screws to form a fixing seat. The fixing seat has rotating grooves on both sides that cooperate with the rotating sections. The first and second net-collecting poles are rotatably connected to the fixing seat via the rotating sections and rotating grooves. When the adjustment button is pressed, the first and second net-collecting poles are released from locking and can be quickly rotated and folded through the rotating sections.

[0010] The rotating section of this invention has a limiting section at the end away from either the first or second net-collecting pole. The limiting section is fixedly connected to the rotating section, and the diameter of the limiting section is larger than that of the rotating section. The fixed base has connecting grooves on both sides that cooperate with the limiting section. The outer wall of the limiting section is rotatably connected to the inner wall of the connecting groove, so as to limit the first and second net-collecting poles through the limiting section and prevent the first and second net-collecting poles from detaching from the fixed base.

[0011] A landing net includes a fixed pole and a landing net ring, characterized in that: a landing net pole folding device as described above is provided between the fixed pole and the landing net ring; a first fixing component and / or a second fixing component are fixedly connected to the fixed pole; one end of the landing net ring is fixedly connected to a first landing net pole and the other end is fixedly connected to a second landing net pole; and a net bag is installed on the landing net ring.

[0030] A landing net includes a fixed pole and a landing net ring, characterized in that: a landing net pole folding device as described above is provided between the fixed pole and the landing net ring; the first fixing component 3 and / or the second fixing component 4 are fixedly connected to the fixed pole; one end of the landing net ring is fixedly connected to the first landing net pole 1 and the other end is fixedly connected to the second landing net pole 2; and a net bag is installed on the landing net ring so that the landing net can be folded and unfolded through the landing net pole folding device, making it convenient to put away and take out.

[0031] As attached Figure 1-8 For ease of description, please refer to the attached document. Figure 1 To illustrate the location, refer to the attached diagram. Net-flying pole 1 is on the left, net-flying pole 2 is on the right, rotating section 23 and limiting section 25 are in front, adjustment button 13 is at the rear, fixing component 3 is on top, and fixing component 4 is at the bottom. Fixing components 3 and 4 are fastened together and fixed with screws to form a fixing base 24. For ease of installation, fixing component 4 can consist of two parts: the front part connects to fixing component 3 for easy installation of the rotating section 23 and limiting section 25 of net-flying poles 1 and 2, and the rear part connects to fixing component 3 to install the flip-over folding mechanism 5. Both the front and rear parts of fixing component 4 are fastened to fixing component 3 and fixed with it using screws. Before use, place the net bag over the net ring, insert both ends of the net ring into landing net pole 1 and landing net pole 2 respectively, and fix the net ring to landing net pole 1 and landing net pole 2 with screws. Install the fixing rod on the fixing base 24, and use the fixing rod to catch fish with the net. When in use, the plug-in block 9 and the limiting slot 10 are plugged in together. The left end of the limiting block 1 7 is placed in the positioning slot 11 of the net-catching rod 1, and the right end of the limiting block 2 8 is placed in the positioning slot 11 of the net-catching rod 2. That is, the net-catching rod 1 and the net-catching rod 2 are fixedly connected to the fixed seat 24 for fishing. When finished, the fixed seat 24 is rotated 180 degrees so that the fixed component 2 is on top and the fixed component 1 is on the bottom. The adjustment button 13 is pressed manually. The adjustment button 13 drives the adjusting block 1 14 and the adjusting block 2 15 through the adjusting rod 12 to squeeze the limiting rod 2 8 and the limiting rod 1 7. This causes the limiting rod 2 8 and the limiting rod 1 7 to squeeze the spring 16 respectively. The limiting rod 2 8 and the limiting rod 1 7 retract into the fixed seat 24. At this time, the net-catching rod 1 and the net-catching rod 2 rotate downward under their own gravity, realizing the folding of the net-catching rod 1 and the net-catching rod 2. The adjustment button 13 is then released. When it is necessary to unfold the net-laying rods 1 and 2, release the net-laying rods 1 and 2, then hold the connection between the fixing base 24 and the fixing rod, and rotate the fixing base 24 180° so that fixing component 1 is on top and fixing component 2 is on the bottom. At this time, the net-laying rods 1 and 2 rotate downward under their own weight. Under the guidance of the inclined guide surface at the left end of the limiting rod 7 and the inclined guide surface at the right end of the limiting rod 2, the insertion blocks 9 of the net-laying rods 1 and 2 press the limiting rods 7 and 2, automatically locking into the limiting slots 10. Then, under the rebound force of the spring 16, the limiting blocks 7 and 2 automatically extend. The nets are locked and fixed in the positioning grooves 11 of the first net pole 1 and the second net pole 2. The folding and unfolding operation of this utility model is simple and can be completed with one hand. Moreover, when using this utility model, the fixing component 1 is on top. When folding, the first net pole 1 and the second net pole 2 need to be flipped from bottom to top, that is, folded towards the fixing component 1. This means that even if the adjustment button 13 is accidentally touched when fishing, the first net pole 1 and the second net pole 2 can only be flipped upward because they are restricted by the limiting slot 10 and cannot be flipped downward. Therefore, even if the adjustment button 13 is accidentally touched, the first net pole 1 and the second net pole 2 will not be folded. The structure has good stability and high safety and efficiency in fishing.

[0032] This utility model, due to the above-mentioned structure, has the advantages of ingenious structure, one-handed operation, smooth folding, stable structure, and high efficiency in catching fish.
