[0002] A fishing net with adjustable sinking depth is a fishing net with an adjustable function, which can adjust the sinking depth of the net during fishing according to needs. This kind of fishing net is usually made of materials with certain elasticity, such as nylon, polyester fiber, etc. By adding an adjustment device to the design of the fishing net, fishermen can change the sinking depth of the net by pulling or loosening the device.

[0003] The publication number CN207927594U discloses a fishing net with adjustable netting depth, including a fishing net, a first sleeve rod, a second sleeve rod, and a fishing net depth line. A lead block is suspended below the fishing net through a counterweight wire. The fishing net is wound around the second sleeve rod through the fishing net depth line. When adjusting the height of the existing fishing net with adjustable netting depth, the main method is to rotate the threaded rod to drive the rope to rise. The reason for using the threaded rod for adjustment is that the rope can be automatically limited after loosening the threaded rod. However, when lowering the fishing net, it is still necessary to rotate the threaded rod to adjust the depth. When the depth is large, it is necessary to rotate many circles, resulting in a very tiring adjustment process. Summary of the Utility Model

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-4 , the present invention provides a technical solution: A fishing net with adjustable sinking depth, including a first support plate 1, a second support plate 2 arranged below the first support plate 1, a fishing net main body 3 fixedly connected below the second support plate 2, a rotating mechanism 4 arranged above the first support plate 1, and a pushing mechanism 5 between the second support plate 2 and the first support plate 1;

[0021] The rotating mechanism 4 includes a fourth support plate 401 fixedly connected above the first support plate 1, a rotating rod 402 rotatably connected inside the fourth support plate 401, a rotating disk 403 fixedly connected to one end of the rotating rod 402, a first hole 404 arranged in the middle inside the first support plate 1, a rope 405 arranged inside the first hole 404, the rope 405 is fixedly connected to the second support plate 2, a baffle 406 is fixedly connected to the outside of the rope 405, a first groove 407 is arranged inside the baffle 406, a limiting plate 408 is arranged inside the first groove 407, the baffles 406 are equidistantly distributed on the outside of the rope 405, and the external structure of the baffle 406 is frustum-shaped, so that the baffle 406 can push the limiting plate 408 to move to both sides along the rope 405.

[0022] The driving mechanism 5 includes a third support plate 501 fixedly connected to the lower surface of the first support plate 1. A threaded rod 502 is threadedly connected inside the third support plate 501. One side of the threaded rod 502 close to the first support plate 1 is rotatably connected to a push plate 503. A guide hole 504 is provided inside the push plate 503. A guide rod 505 is provided inside the guide hole 504. Guide grooves 506 are provided inside both sides of the first support plate 1. Slide grooves 507 communicate with the upper sides of both sides of the guide grooves 506. A slider 508 is provided inside the slide grooves 507. The slider 508 is fixedly connected to the guide rod 505. The lower end of the guide rod 505 is fixedly connected to an elastic telescopic rod 509. The elastic telescopic rod 509 is horizontally slidably connected to the first support plate 1. The limiting plate 408 is fixedly connected to the elastic telescopic rod 509. The external structure of the guide hole 504 is an inclined straight line, and the cooperation mode between the guide hole 504 and the guide rod 505 is clearance fit. The external structure of the guide groove 506 is a horizontal straight line, and the cooperation mode between the guide groove 506 and the guide rod 505 is clearance fit. When the guide hole 504 moves horizontally, it can push the guide rod 505 to move horizontally along the track of the guide groove 506. The upper and lower outer surfaces of the slider 508 are in contact with the upper and lower inner surfaces of the slide groove 507, and the central axis of the slider 508 is perpendicular to the central axis of the guide rod 505, so that the slider 508 will not shake when sliding horizontally inside the slide groove 507. The distance between the limiting plates 408 in the natural state of the elastic telescopic rod 509 is smaller than the distance between the first grooves 407, so that the limiting plates 408 will be within the control range of the first grooves 407 when the elastic telescopic rod 509 is in the natural state.

[0023] When it is necessary to raise the depth of the fishing net main body 3, rotate the rotating rod 402 to drive the rotating disk 403 to rotate, drive the rope 405 and the baffle 406 to move upward. Since the external structure of the baffle 406 is frustum-shaped, when the baffle 406 contacts the elastic telescopic rod 509 and the limiting plate 408, it pushes the elastic telescopic rod 509 and the limiting plate 408 to move outward. When the baffle 406 moves beyond the range of the limiting plate 408, the elastic telescopic rod 509 and the limiting plate 408 reset. The first groove 407 inside the baffle 406 limits the limiting plate 408, so that the elastic telescopic rod 509 supports and limits the baffle 406, raises the depth of the fishing net main body 3, and moves the fishing net main body 3 upward by a certain distance. When it is necessary to lower the depth of the fishing net main body 3, rotate the threaded rod 502 to drive the push plate 503 to rotate, so that the guide hole 504 moves backward, so that the guide rod 505 and the elastic telescopic rod 509 move to both sides, so that the limiting plate 408 can also move out of the control range of the first groove 407, so that the second support plate 2, the fishing net main body 3, the rope 405 and the baffle 406 move downward under the action of gravity, and it is not necessary for the staff to rotate slowly for many circles to complete the downward height adjustment, thus achieving the purpose of making the adjustment process easier.
