Description

Technical Field

[0001] This utility model relates to the field of fishing net technology, specifically to a fishing net with adjustable mesh size. Background Technology

[0002] Fishing nets are nets used for catching fish. In ancient times, people used coarse cloth and hemp as raw materials to make fishing nets by binding and rolling them. Although these nets were easily perishable and not very durable, their fishing efficiency was greatly improved. With the development of the fishing industry, the targets of fishing were no longer limited to fish, and the fishing tools also evolved accordingly.

[0003] The mesh size of a fishing net determines the size of the fish caught, so adjusting the mesh size allows you to catch different kinds of fish under different circumstances. However, the mesh size of a traditional fishing net is fixed, and adjusting it may require replacing the entire net, which is costly. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fishing net with adjustable mesh size.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An adjustable mesh fishing net includes a frame. Grooves are provided along the perimeter of the frame. Several net wires, each with two ends passing through opposite grooves on opposite sides of the frame, are slidably disposed within the grooves. Two clamping plates, rotating along the X-axis and Y-axis respectively, are rotatably disposed at two corners of the frame. Two fixing plates, each abutting one side of one of the clamping plates, are fixed at the other corners of the frame. Telescopic rods are mounted on the fixing plates, with pressure springs wound around the telescopic rods, and limiting plates abutting the other side of the clamping plates at the ends of the telescopic rods.

[0007] Preferably, the two fixing plates are fixed at the same corner of the frame, and the rotation centers of the two clamps are diagonally opposite.

[0008] Preferably, the two fixing plates and the two limiting plates are all located on the same plane.

[0009] Preferably, the width of the groove is no more than twice the diameter of the network cable.

[0010] Preferably, the mesh wires in the two opposite grooves of the frame are perpendicular to the mesh wires in the other two grooves and are intertwined.

[0011] Preferably, one end of the network cable is provided with a limiting ball with a diameter greater than the width of the groove, the side of the network cable near the limiting ball is located in the groove near the fixed plate and is clamped by a clamping plate, and the other end of the network cable is knotted.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model ensures the stability of the fishing net size through the frame. The size of the mesh is changed by the sliding of the net wires in the groove, which changes the spacing between each pair of net wires. The number of net wires can be increased or decreased according to the actual situation. At the same time, the rotation of the clamping plate gradually presses the already positioned net wires until all net wires are pressed. Then, the telescopic rod drives the limiting plate to move, which moves one side of the clamping plate to abut against the fixed plate. After the limiting plate is released, the rebound force of the pressure spring drives the limiting plate to abut against the other side of the clamping plate, thereby achieving the clamping of the clamping plate and ensuring the stability of the net wires.

[0014] 2. This utility model avoids mutual interference when the clamping plates rotate by fixing two fixing plates at the same corner position of the frame. At the same time, the fact that the two fixing plates and the two limiting plates are all located on the same plane allows the adjustment work to be carried out on one plane, thereby improving the efficiency of the adjustment work.

[0022] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0023] like Figure 1 As shown, an adjustable mesh fishing net according to this utility model includes a frame 1, as follows: Figure 2 As shown, the frame 1 has grooves 4 running through its sides. The frame 1 ensures the stability of the fishing net size. Several net lines 2 are slidably arranged in the grooves 4, with both ends passing through the two opposite grooves 4 on the sides of the frame 1. One end of the net line 2 is equipped with a limiting ball with a diameter larger than the width of the groove 4, and the other end of the net line 2 is knotted. The limiting ball on one side of the net line 2 is more stable than the knot. The knot on the other side of the net line 2 ensures that the net line 2 can freely pass through the groove 4, so the number can be increased or decreased. The width of the groove 4 is no more than twice the diameter of the net line 2, ensuring the spacing of the net lines 2 in the groove 4 and thus ensuring the stability of the fishing operation. The net lines 2 in the two opposite grooves 4 on the sides of the frame 1 are perpendicular to the net lines 2 in the other two grooves 4 and are intertwined, further ensuring the stability of the connection between the net lines 2 and thus ensuring the stability of the fishing operation.

[0024] Two clamping plates 3 are rotatably mounted at the two corners of the frame 1, rotating along the X and Y axes respectively. Two fixing plates 5 are fixed at the other corners of the frame 1, each abutting against one side of one of the clamping plates 3. Figure 4 As shown, a telescopic rod 6 is provided on the fixed plate 5. A pressure spring 7 is wound on the telescopic rod 6, and a limiting plate 8 is provided at the end of the telescopic rod 6 to abut against the other side of the clamping plate 3. The mesh size is changed by sliding the mesh wire 2 in the slide groove 4 to change the spacing between each pair of mesh wire 2. The number of mesh wire 2 can be increased or decreased according to the actual situation. At the same time, the clamping plate 3 is rotated to gradually press and fix the already positioned mesh wire 2 until all the mesh wire 2 are pressed and fixed. Then, the telescopic rod 6 drives the limiting plate 8 to move, thereby moving one side of the clamping plate 3 to abut against the fixed plate 5. After the limiting plate 8 is released, the rebound force of the pressure spring 7 drives the limiting plate 8 to abut against the other side of the clamping plate 3, so that the side of the mesh wire 2 closest to the limiting ball is located in the slide groove 4 closest to the fixed plate 5 and is clamped by the clamping plate 3, thereby achieving the clamping of the clamping plate 3 and ensuring the stability of the mesh wire 2.

[0025] like Figure 3 As shown, the two fixing plates 5 are fixed at the same corner position of the frame 1, and the rotation centers of the two clamping plates 3 are diagonally opposite. By fixing the two fixing plates 5 at the same corner position of the frame 1, the clamping plates 3 are prevented from affecting each other when rotating, thus ensuring that the adjustment is carried out stably at the same time. The two fixing plates 5 and the two limiting plates 8 are all located on the same plane. By the fact that the two fixing plates 5 and the two limiting plates 8 are all located on the same plane, the adjustment work can be carried out on one plane, thereby improving the efficiency of the adjustment work.

[0026] When the mesh size of the fishing net needs to be adjusted, the limiting plate 8 is moved to disengage from the clamping plate 3, allowing the clamping plate 3 to rotate and release the clamping plate 3 from the net line 2. The mesh size is changed by moving the net line 2, and the number of net lines 2 is increased or decreased according to the actual situation. The clamping plate 3 is used to press the positioned net lines 2 until all net lines 2 are pressed. The limiting plate 8 is moved so that one side of the clamping plate 3 contacts the fixing plate 5 and then the limiting plate 8 is released. The pressure spring 7 returns and causes the limiting plate 8 to contact the other side of the clamping plate 3 to complete the clamping of the clamping plate 3.

[0027] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
