Description

Technical Field

[0001] This utility model relates to the field of fishery fishing technology, and in particular to a foldable, multi-functional inclined span net cage. Background Technology

[0002] Net cages, widely used in fishing, hunting, pet transportation, and outdoor item storage, typically consist of a frame and a mesh surface. The frame forms the overall structure, providing support and shaping, and is generally made of metal, plastic, or wood to ensure sufficient strength to support the items. The mesh surface, attached to the frame, is usually made of fine nylon or wire mesh and is used to hold and isolate the items inside, preventing them from escaping or falling.

[0003] Taking a common traditional fishing net cage as an example, many fishermen use a simple metal frame with a nylon net, and its limiting method is usually a hook type. The specific operation is to weld or rivet a simple metal hook to each side of the frame at the folding part of the net cage. After the net cage is folded, take a wire of moderate thickness, bend it into a U shape by hand, and then hang the two ends of the U-shaped wire on the corresponding hooks to fix the folded state.

[0004] Existing technologies rely solely on simple hooks to connect the wire and hooks, resulting in extremely poor connection stability. Under everyday conditions such as the rocking of fishing boats and the swaying during transport, the wire easily slips off the hook, causing the net cage to deploy unexpectedly. Furthermore, the U-shaped wire is prone to fatigue fracture after repeated use and bending, further reducing the reliability of the locking mechanism. Fishermen need to frequently inspect and replace the wire, increasing operating costs and complexity. Therefore, a foldable, multi-functional, slanted-span net cage is proposed to address these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a foldable multi-functional inclined span cage, which aims to improve the problem that the limiting means in the prior art are simple and cannot ensure the stability of the cage after folding.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a foldable multi-functional inclined span net cage, including a base frame and a top frame. A bottom rod is hinged to the inner wall of the base frame via a pin, and hinge rods B are respectively hinged to both ends of the bottom rod. A top rod is hinged to the inner wall of the top frame via a pin, and hinge rods A are hinged to both ends of the top rod. Fishing netting is filled between the bottom rod, top rod, hinge rods A and B. The hinge rods A and B are staggered front to back, and contact and hinge at their intersection. The base frame and top frame... Support structures and limiting structures are respectively provided between the frames. The limiting structure includes a handle, and a shell is fixedly connected to the back of the handle. The top of the shell is open, and the inner wall of the shell contacts and slides to connect to a movable plate. A spring is provided inside the shell. The top end of the spring is fixedly connected to the bottom of the movable plate, and the bottom end of the spring is fixedly connected to the bottom inner wall of the shell. An inclined block is fixedly connected to the front of the movable plate, and a locking plate is fixedly connected to the front of the top frame. The top of the locking plate has a locking groove, and the inclined block is configured to cooperate with the locking plate.

[0007] As a further description of the above technical solution: the support structure includes a support rod, the top end of which is hinged to the inner side of the top frame, a storage groove is provided on the side of the support rod, a folding rod is hinged to the groove wall of the storage groove, the outer side of the folding rod abuts against the storage groove, a plug is fixedly connected to the bottom end of the folding rod, and slots are provided on both inner walls of the base frame.

[0008] As a further description of the above technical solution: there are two support structures, which are staggered front to back; the two support rods are intersecting and staggered front to back; the two support rods are in contact and rotatably connected at their intersection; and two support structures are distributed around the base frame and top frame respectively.

[0009] As a further description of the above technical solution: the card plate has an opening on one side, and the shape of the card slot is adapted to the shape of the inclined block.

[0010] As a further description of the above technical solution: a cover plate is hinged to the top of the top frame, a mesh plate is placed on the inner side of the top of the top frame, and a magnet is fixedly connected to the side of the cover plate. The side of the cover plate is magnetically connected to the top of the top frame through the magnet.

[0011] As a further description of the above technical solution: the number of springs is two, and the two springs are symmetrically arranged on both sides of the slide groove.

[0012] As a further description of the above technical solution: the handle is U-shaped, a rotating plate is hinged to the front of the base frame, and the back of the handle is fixedly connected to the front of the rotating plate.

[0013] As a further description of the above technical solution: the slot is staggered front and back, the slot shape is adapted to the shape of the plug, and the outer wall of the plug abuts against the slot wall.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the limiting structure can effectively fix the folded net cage. The handle is rotated to drive the inclined block to cooperate with the card plate. Driven by the elastic potential energy of the spring, the inclined block is accurately locked into the card slot, preventing the top frame and bottom frame from unfolding accidentally and ensuring safety during carrying. Users can easily perform limiting and releasing operations to meet the needs of different scenarios.

[0016] 2. In this utility model, the supporting components provide stable support for the wire mesh cage. The design of the folding rod and the storage slot realizes efficient use of space. When folded, it is stored inside without taking up extra space. When unfolded, it is turned out and tightly cooperates with the base frame slot through the plug, which strengthens the overall support strength, enabling the wire mesh cage to withstand greater external forces and ensuring safe use. The two staggered and cross-shaped support structures are evenly distributed around the base frame and top frame, distributing the force in all directions and avoiding uneven local force distribution. This allows the wire mesh cage to remain stable under various working conditions and extends its service life. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1 - Figure 3This utility model provides an embodiment of a foldable, multi-functional inclined wire mesh cage, including a base frame 1 and a top frame 2. The base frame 1 serves as the basic support for the entire wire mesh cage, bearing the weight of the upper structure and the items placed inside, ensuring the stability of the cage. The top frame 2 cooperates with the base frame 1 to form the main frame of the wire mesh cage, defining its spatial range. A cover plate 5 is hinged to the top of the top frame 2. This hinged design allows the cover plate 5 to open and close flexibly, facilitating the user to place or remove items into the cage. Simultaneously, when closed, it seals the cage, preventing items from falling out or escaping. A mesh plate 6 is placed on the inner side of the top of the top frame 2. As a second safety measure, plate 6 further prevents the cover plate 5 from accidentally opening and allowing any living creatures inside the fishing net 10 to escape if the cover plate 5 becomes loose. This provides double protection for the safety of the items inside the net cage. A magnet is fixedly connected to the side of the cover plate 5, and the side of the cover plate 5 is magnetically connected to the top of the top frame 2 via the magnet. The magnetic attraction of the magnet ensures that the cover plate 5 fits tightly against the top frame 2 when closed, enhancing the sealing. This connection method is simple and convenient, requiring no additional complex fixing devices, making it easy for the user to operate. A base rod 11 is hinged to the inner wall of the base frame 1 via a pin. The base rod 11 serves as a folding mechanism. A crucial structural component, the bottom rod 11, can rotate flexibly around a pivot, providing key support for the subsequent folding of the net cage. Hinged rods B4 are hinged to both ends of the bottom rod 11. Through their connection to the bottom rod 11 and their own rotational characteristics, they work together to achieve the folding deformation of the bottom of the net cage, changing its shape to meet different usage needs, such as saving space during storage. The inner wall of the top frame 2 is hinged to a top rod 12 via a pivot. Similarly, the top rod 12 plays a key folding support role at the top of the net cage, guiding the folding motion of the top of the net cage in conjunction with the structure of the top frame 2. Fishing netting 10 is filled between the bottom rod 11, top rod 12, hinged rods A3 and B4. The top rod 12 is hinged to both ends with hinge rods A3. The hinge rods A3 and B4 are staggered front and back. This staggered arrangement allows them to interlock and cooperate during folding, orderly changing the shape of the cage and avoiding structural conflicts. The hinge rods A3 and B4 contact and hinge at their intersection, ensuring the continuity and smoothness of the folding action. This allows the cage to be folded or unfolded smoothly, adapting to different scenarios, such as folding to reduce volume when carrying and unfolding to increase internal space when in use. The base frame 1 and the top frame 2 are respectively provided with a support structure 7 and a limiting structure 9.

[0028] Reference Figure 4 , Figure 5The limiting structure 9 includes a handle 908, which is U-shaped for easy gripping and provides a comfortable point of leverage when carrying the cage, facilitating lifting or carrying it diagonally. A rotating plate 907 is hinged to the front of the base frame 1, providing a fulcrum for the rotation of the handle 908, allowing for flexible adjustment of its position. The back of the handle 908 is fixedly connected to the front of the rotating plate 907, and a housing 904 is fixedly connected to the back of the handle 908. The top opening of the housing 904 is provided with… The movable plate 903 is positioned to facilitate sliding up and down within the outer casing 904. The inner wall of the outer casing 904 contacts and slidably connects to the movable plate 903. Two springs 905 are symmetrically arranged on both sides of the slide groove 906, utilizing their elastic potential energy to play a crucial driving and resetting role throughout the limiting process. When the inclined block 902 is compressed, the spring 905 is compressed to store energy; when the external force disappears, the spring 905 releases the energy, pushing... The inclined block 902 resets, ensuring the reliability and stability of the limiting structure 9. The top of the spring 905 is fixedly connected to the bottom of the movable plate 903, and the bottom of the spring 905 is fixedly connected to the bottom inner wall of the outer shell 904. The inclined block 902 is fixedly connected to the front of the movable plate 903. When the clamping plate 901 is pressed by the clamping plate 901, it can slide upward smoothly. After entering the top slot of the clamping plate 901, it can rely on its own shape to fit tightly with the slot, thereby limiting the top frame 2 and the bottom frame 1 and preventing the folded cage from accidentally unfolding. The top frame 2 A card plate 901 is fixedly connected to the front of the cage. A slot is provided on the top of the card plate 901. An inclined block 902 is set to cooperate with the card plate 901. An opening is provided on one side of the card plate 901 to facilitate the smooth passage of the movable plate 903 when the limit is released, avoiding jamming between parts, making the operation smoother and improving the user experience. The shape of the slot matches the shape of the inclined block 902, ensuring that the inclined block 902 can accurately enter the slot and be stably locked, achieving a reliable limiting effect and ensuring the safety of the cage in the folded and carried state.

[0029] Reference Figure 6 , Figure 7The support structure 7 includes a support rod 701, the top of which is hinged to the inner side of the top frame 2. This hinge allows the support rod 701 to be flexibly adjusted in angle, providing strong support for the top frame 2 when the cage is unfolded, enhancing the overall stability of the cage, and preventing the top frame 2 from sinking or deforming due to the weight of the items it bears. A storage groove 704 is provided on the side of the support rod 701, and a folding rod 702 is hinged to the wall of the storage groove 704. The storage groove 704 provides storage space for the folding rod 702 when the cage is folded. The folding rod 702 can be stored away to avoid taking up extra space. The outer side of the folding rod 702 abuts against the storage slot 704. When it is necessary to extend the length of the support rod 701, the folding rod 702 can be easily rotated out of the storage slot 704 to provide support. The bottom end of the folding rod 702 is fixedly connected to the insert block 703. Slots are provided on both sides of the inner wall of the base frame 1. The insert block 703 is used to cooperate with the slots on both sides of the inner wall of the base frame 1. By inserting into the slots, the connection between the support rod 701 and the base frame 1 is made more stable and further strengthened. To ensure the safety of the wire mesh cage during use, two support structures 7 are used, staggered one after the other. This staggered layout makes the support force distribution more even, avoiding uneven local stress and ensuring the stability of the wire mesh cage from all directions. The two support rods 701 are arranged in a cross shape and staggered one after the other. The cross structure can utilize mechanical principles to enhance the overall support strength and improve the wire mesh cage's ability to withstand forces from different directions. The two support rods 701 are in contact and rotatably connected at their intersection, ensuring that the support rods 701 can flexibly adjust their posture during unfolding and folding to adapt to changes in the shape of the wire mesh cage, making operation convenient and efficient. The slots are staggered one after the other, and the shape of the slots matches the shape of the inserts 703. The outer wall of the inserts 703 abuts against the wall of the slots. There are two support structures 7 distributed around the base frame 1 and the top frame 2. The all-round support layout provides stable support for the wire mesh cage from all angles. Whether placing stationary items or dealing with shaking during transportation, it can ensure the stability of the wire mesh cage structure and the safety of the items inside.

[0030] Working principle: When the cover plate 5 is opened, the mesh plate 6 acts as a second safety measure to prevent the cover plate 5 from opening accidentally and causing the live animals inside the fishing net 10 to escape. When the top frame 2 and the bottom frame 1 are folded or unfolded, the hinge rod A3 rotates around the two ends of the top rod 12, and the hinge rod B4 rotates around the two ends of the bottom rod 11. The adjacent ends of the hinge rod A3 and the hinge rod B4 rotate in opposite directions, thereby achieving the folding or unfolding effect of the net cage. When the top frame 2 and the bottom frame 1 are folded, the bottom of the top frame 2 contacts the top of the bottom frame 1. When the handle 908 is rotated through the rotating plate 907, the inclined block 902 is squeezed by the clamping plate 901, which drives the movable plate 903 to move upward in the slide groove 906 of the outer shell 904. When the inclined block 902 enters the top of the clamping plate 901, the longitudinal elastic potential energy of the spring 905 drives the inclined block 902 into the slot, thereby realizing the folding effect of the top frame 2 and the bottom frame 1. The cage is designed to be easily carried by gripping the handle 908, or by passing the strap through the handle 908 and carrying the folded cage diagonally. To release the restriction between the top frame 2 and the bottom frame 1, simply push the inclined block 902 upwards until it disengages from the slot, then rotate the movable plate 903 in the opposite direction. The movable plate 903 rotates around the front of the bottom frame 1 via the rotating plate 907 below. At this point, the movable plate 903 separates from the slot 901 after passing through the opening of the slot 901, thus releasing the restriction between the top frame 2 and the bottom frame 1. The top frame 2 and the bottom frame 1 can then be unfolded. The folding rod 702 can be rotated from the storage slot 704 to extend the length of the support rod 701. Then, the bottom insert 703 of the folding rod 702 can be pressed against the slot to support the top frame 2. After the cage is unfolded, the bottom frame 1 provides support and restriction for the top frame 2.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
