Description

Technical Field

[0001] This utility model relates to the field of fishing gear, specifically to a compressed landing net. Background Technology

[0002] With the development of technology, people's lives have undergone tremendous changes. Now many people enjoy fishing in the wild. In the process of fishing in the wild, in addition to fishing rods, landing nets are also essential. When a big fish is hooked and too heavy, the fishing rod cannot bear the weight and pulls the fish to the riverbank. At this time, we need to use a landing net to catch the fish. However, existing landing nets are all assembled directly with rings and telescopic rods, and their width cannot be changed, making them inconvenient to carry. Utility Model Content

[0051] The embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0052] As shown in the figure, a compressed landing net includes a net bag 1 and a support frame supporting the net bag 1. The support frame includes an opening and closing bracket and several support rods 3. Adjacent support rods 3 are hinged to each other, and the first and last support rods 3 are respectively connected to the opening and closing bracket. The support frame has a first state of being open in a circle and a second state of being closed in a figure-eight shape. When the opening and closing bracket of this technical solution is in the state of being open to both sides, the support rods will be open in a circle, which can be used to scoop fish. When the opening and closing bracket is in the state of being closed in the middle, the support rods will be closed inward in a figure-eight shape, so that the landing net can be put into a storage bag. It has the advantages of simple structure, convenient carrying and storage in fishing tackle bag, and space saving.

[0053] The opening and closing bracket includes a first mounting base 2, a first toothed member rotatably mounted on both sides inside the first mounting base 2, and a transmission mechanism for driving the first toothed member to rotate. The first toothed member is provided with a first connecting strip 6 extending radially outward and interlocking with the support rod 3. The transmission mechanism can drive the first toothed members on both sides to rotate towards each other and away from each other. The first toothed member controls the first support rod and the fourth support rod to swing towards the center and outward through the first connecting strip.

[0054] The opening and closing bracket in this technical solution has two embodiments;

[0055] Example 1: The first toothed component is a gear 41, and the transmission mechanism includes:

[0056] A double-sided rack 42 is disposed between two gears 41 and meshes with the gears 41.

[0057] A spiral sleeve 43 is rotatably mounted on the first mounting base 2 and has a spiral groove 45 on its inner wall surface;

[0058] The first connector 44 is installed at the bottom of the first mounting base 2 by thread engagement and abuts against the bottom surface of the spiral sleeve 43;

[0059] The double-sided rack 42 has a first mounting base 2 extending out from its bottom and a first pin 46 inserted into the spiral groove 45. The spiral sleeve 43 has a first action of driving the double-sided rack 42 down through the first pin 46 when rotating in the forward direction, and a second action of driving the double-sided rack 42 up through the first pin 46 when rotating in the reverse direction. Figures 1 to 4 As shown, the spiral sleeve is clamped by the stepped surfaces of the first connector and the first mounting base. The spiral sleeve can only rotate. The end of the first pin is embedded in the spiral groove, and the double-sided rack moves up and down when the spiral sleeve rotates. When the double-sided rack moves upward, the first connecting strips extending from the gears on both sides will separate and open. When the double-sided rack moves downward, the first connecting strips extending from the gears on both sides will close together. The principle of the spiral sleeve driving the double-sided rack to move up and down is the same as the principle of lipstick telescopic movement.

[0060] The double-sided rack 42 has horizontally extending support plates 47 on both sides. The end of the support plate 47 is provided with a tooth block 48 that can be inserted into the gear 41 and restricts the rotation of the gear 41. The tooth block will rise and fall synchronously with the double-sided rack. When it rises to a certain height, the tooth block will be inserted into the gear, thereby restricting the rotation of the gear. This can prevent the support rods on the first connecting strips on both sides from unfolding too much, ensuring that the support rods unfold into a circle, preventing swaying, and providing fixation.

[0061] The first pin 46 extends from the front and rear side walls of the first mounting base 2. The front and rear sides of the first mounting base 2 are provided with vertically arranged strip holes 21 for the first pin 46 to slide. There are two symmetrical spiral grooves 45. Copper sleeves 49 for lubrication are provided at both ends of the first pin 46. The first pin is fixed to the bottom of the double-sided rack. The movement trajectory of the first pin is always restricted in the strip holes. The two symmetrical spiral grooves can ensure that the first pin is always in a horizontal, stable and synchronous state during the lifting and lowering process.

[0062] Example 2: The first toothed component adopts a worm gear 51, and the transmission mechanism includes:

[0063] The worm 52 is located between the two gears 41 and meshes with the worm wheel 51.

[0064] A rotating shaft 53 is rotatably mounted on the first mounting base 2 and is linked to the worm gear 52.

[0065] The second connector 54 is installed at the bottom end of the first mounting base 2 by means of a threaded connection;

[0066] The rotating shaft 53 has a first action of driving the worm wheel 51 to rotate towards the center through the worm 52 when rotating in the forward direction, and a second action of driving the worm wheel 51 to rotate towards both sides through the worm 52 when rotating in the reverse direction. The rotating shaft is a knurled pin shaft. The connection between the rotating shaft and the worm can be a key linkage connection or an interference fit. The rotating shaft drives the worm to rotate, and the worm then drives the worm wheel to rotate. The first connecting strips on the two worm wheels can also realize the action of opening to both sides and closing towards the center.

[0067] The first mounting base 2 is provided with a bearing 55 for the insertion of the rotating shaft 53 at the position between the second connector 54 and the worm gear 52. The bearing is a thrust ball bearing to reduce frictional resistance.

[0068] Example 3: The opening and closing bracket includes a second mounting base 12, a second toothed member 13 rotatably mounted on both sides inside the second mounting base 12 and meshing with each other, and a limiting component for limiting the rotation of the second toothed member 13. The second toothed members 13 are symmetrical to each other and each is provided with a second connecting strip 14 that extends radially outward and is inserted into the support rod 3. In this example, the limiting component can abut against the second toothed member, so that the second toothed member is always kept in an open state. If the limiting component does not abut against the second toothed member, the opening and closing bracket can open and close freely.

[0069] The limiting components include:

[0070] The limiting post 15 is disposed inside the second mounting base 12 and located below the second toothed member 13;

[0071] The sliding pin 16 is inserted radially into the bottom of the limiting post 15;

[0072] The sliding groove 17 is provided on the front and rear sides of the second mounting base 12 and is in an inverted L shape;

[0073] The two ends of the sliding pin 16 extend from the sliding groove 17 and are provided with pressing sleeves 18. The second toothed member 13 is provided with a first plane 19 opposite to each other and a second plane 20 that contacts the limiting post 15. The second toothed member 13 has a first state when the first planes 19 are in contact with each other and a second state when the first planes 19 are far apart from each other. The limiting post 15 has a first action of pushing the second plane 20 upward when the second toothed member 13 is in the first state and a second action of moving downward when the second toothed member 13 is in the second state. The operator can press his finger on the pressing sleeve and then push the sliding pin to move in the sliding groove. When the sliding pin is at the bottom of the sliding groove, the limiting post does not contact the second toothed member, so the second toothed member can rotate freely and the two second connecting bars can swing freely.

[0074] When the second connecting bar is opened to its maximum angle, the first planes will contact each other and restrict the second toothed part from continuing to rotate. Then, when the operator moves the sliding pin to the upper end of the sliding groove, the limiting post will abut against the second plane of the second toothed part, thus restricting the second toothed part from moving. Finally, the sliding pin is moved to the right end of the sliding groove, so that the limiting post will keep pressing against the second toothed part.

[0075] The number of support rods 3 is four. A first joint assembly 7 is provided between the first support rod 3 and the second support rod 3, and between the third support rod 3 and the fourth support rod 3. A second joint assembly 8 is provided between the second support rod 3 and the third support rod 3. The first joint assembly 7 includes:

[0076] The first concave joint 71 has its end inserted into the support rod 3;

[0077] The first convex joint 72 has its end inserted into another support rod 3;

[0078] The other end of the first concave joint 71 and the other end of the first convex joint 72 are hinged to each other;

[0079] The second joint assembly 8 includes:

[0080] Two second convex joints 81, the ends of which are inserted into two adjacent support rods 3;

[0081] The second concave joint 82 is hinged between the second convex joints 81;

[0082] A second pin 9 is provided between the first concave joint 71 and the first convex joint 72 and between the second convex joint 81 and the second concave joint 82 to connect the two. The first joint assembly and the second joint assembly can be used to switch the state of the support rod from unfolding into a circle to closing into a figure-eight shape.

[0083] The end of the first concave joint 71 facing the first convex joint 72 and the end face of the second concave joint 82 facing the second convex joint 81 are respectively provided with a clearance slope 10 and an abutment plane 11. When closed into a figure-eight shape, the clearance slope can prevent the relative rotation of the first concave joint 71 and the first convex joint 72 and the second concave joint 82 and the second convex joint 81 from being obstructed. When unfolded into a circle, the abutment plane can prevent the first concave joint 71 and the first convex joint 72 and the second concave joint 82 and the second convex joint 81 from being over-rotated, thus ensuring the structural stability after unfolding into a circle.
