Description

Technical Field

[0001] This application relates to the field of aquaculture equipment technology, and in particular to a two-in-one detachable fishing net. Background Technology

[0002] During the breeding process of fish fry and fingerlings, uneaten feed, feces, decaying aquatic plants, and floating debris often accumulate in the pond. These substances severely damage the aquatic environment, not only consuming dissolved oxygen and causing fish fry to die from oxygen deprivation, but also easily breeding bacteria and parasites, leading to the spread of diseases and reducing the survival rate of fish fry. Therefore, fish farmers often use nets to clean the impurities in the pond to ensure the health of the fish fry and the success of breeding.

[0003] Most common fishing nets on the market are single-function designs, mainly divided into two categories: one is a fishing net with a net bag, suitable for catching fish or suspended debris in the water; the other is a straight-sided net, mainly used for cleaning floating objects on the water surface or trimming aquatic plants. However, in actual use, aquaculture workers often need to frequently change different types of fishing nets according to their operational needs. For example, in the same task, they may need to use both a net bag for catching fish and a straight-sided net for cleaning.

[0004] Although existing fishing nets have a certain degree of detachability in structure, their assembly and disassembly processes are relatively complex and cumbersome, affecting work efficiency. Furthermore, switching functions usually requires additional accessories or tools, increasing usage costs and operational difficulty, making it difficult to meet users' needs for efficient and convenient operation. Therefore, a two-in-one detachable fishing net is proposed. Summary of the Invention

[0024] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0025] This application discloses a two-in-one detachable fishing net, including an outer frame 1, a net bag 2, a straight net 3, and an inner frame 14. The net bag 2 is detachably installed on the bottom surface of the outer frame 1 for catching fish or debris in the water. The straight net 3 is detachably installed inside the inner frame 14 and is suitable for cleaning floating objects or trimming aquatic plants. A box 4 is fixedly installed on one side of the outer surface of the outer frame 1. The outer frame 1 has an insertion port that communicates with the box 4 to facilitate the movement of the inner frame 14. A tube 6 is fixedly connected to the outer surface of the box 4. A control lever 7 is fixedly connected to one side of the inner frame 14. One end of the control lever 7 extends through the outside of the tube 6 to control the movement of the inner frame 14.

[0026] In this embodiment, the switching operation between the net bag 2 and the straight mesh 3 is simple; when the net bag 2 is needed, the inner frame 14 and the straight mesh 3 are simply moved into the box 4 by the lever 7; when the straight mesh 3 is needed, the straight mesh 3 is simply moved out of the box 4 by the lever 7.

[0027] Furthermore, a sleeve plate 12 is fitted onto one end of the control lever 7 located outside the tube body 6. A first spring 11 is fixedly connected between the sleeve plate 12 and the tube body 6. A slide block 10 is fixedly connected to one side of the sleeve plate 12. A slide groove 13 is formed on the outer surface of the tube body 6. The surface of the slide block 10 has a protrusion that matches the slide groove 13. The protrusion is slidably installed inside the slide groove 13. A fixing bolt 16 is inserted into the slide block 10, and the fixing bolt 16 abuts against the inner wall of the slide groove 13. The protrusion can slide within the slide groove 13, thereby guiding the movement of the slide block 10. The fixing bolt 16 is inserted into the slide block 10 to lock the position of the slide block 10 in the slide groove 13, thereby positioning the control lever 7 and the inner frame 14.

[0028] In this embodiment, by setting up structures such as the slide block 10, the first spring 11, and the fixing bolt 16, the straight plate mesh 3 can be extended, adjusted, and positioned.

[0029] Specifically, in the initial state, the inner frame 14 and the straight mesh 3 are located in the box 4, and the first spring 11 is in its original length. When the straight mesh 3 needs to be used, the operator loosens the fixing bolt 16 and pushes the slide 10 along the direction of the tube 6. The protrusion on the surface of the slide 10 cooperates with the groove 13 on the outer surface of the tube 6, and slides in the groove 13, thereby driving the control lever 7 to move forward. The control lever 7 is connected to the inner frame 14, and its movement will drive the inner frame 14 to move out of the box 4. At this time, the first spring 11 is compressed. After the inner frame 14 is completely moved out, the fixing bolt 16 is tightened. The fixing bolt 16 is inserted into the slide 10 and abuts against the inner wall of the groove 13. The friction force fixes the slide 10 in a specific position in the groove 13, thereby realizing the positioning of the control lever 7 and the inner frame 14. At this time, the straight mesh 3 remains in the extended state and can be used for cleaning floating objects or trimming aquatic plants at a distance. If the straight mesh 3 needs to be retracted into the box 4, the operator only needs to loosen the fixing bolt 16, the compressed first spring 11 will extend, and drive the operating lever 7 to move back, so that the inner frame 14 and the straight mesh 3 will move back into the box 4.

[0030] Furthermore, a limiting rod 18 is inserted into one end of the control lever 7 located outside the tube body 6. A limiting hole 19 adapted to the limiting rod 18 is opened on the surface of the sleeve plate 12. The limiting rod 18 is inserted into the limiting hole 19. A pull ring 23 is fixedly connected to one end of the limiting rod 18 away from the limiting hole 19. A second spring 15 is sleeved on the outer surface of the limiting rod 18. One end of the second spring 15 is fixedly connected to the control lever 7, and the other end of the second spring 15 is fixedly connected to the pull ring 23. When the limiting rod 18 is inserted into the limiting hole 19, the inner frame 14 is flush with the outer frame 1.

[0031] In this embodiment, by setting up structures such as slide 10, first spring 11 and fixing bolt 16, the straight plate mesh 3 can be rotated and positioned.

[0032] Specifically, when the straight mesh 3 needs to be rotated and adjusted, the operator can pull the pull ring 23, and the limiting rod 18 will disengage from the limiting hole 19, releasing the limiting effect on the operating lever 7. The second spring 15 is stretched during this process, and the stretched second spring 15 provides a restoring force, so that the limiting rod 18 can automatically return to the limiting hole 19 after the pull ring 23 is released.

[0033] With the limiting rod 18 disengaged from the limiting hole 19, the user rotates the control lever 7 to rotate the inner frame 14 and the straight mesh 3. This operation allows the debris collected on the straight mesh 3 to be guided into the net bag 2. This process temporarily dumps the debris from the straight mesh 3 into the net bag 2, achieving seamless connection of the retrieval operation and improving work efficiency. After the debris is completely transferred to the net bag 2, the operator rotates the control lever 7, aligns the limiting rod 18 with the limiting hole 19, and then releases the pull ring 23. Under the rebound force of the second spring 15, the limiting rod 18 automatically inserts into the limiting hole 19, the control lever 7 returns to its initial limiting state, and the straight mesh 3 is once again flush with the outer frame 1, ready for the next round of operation.

[0034] To ensure stability and a good seal between the inner frame 14 and the outer frame 1 during rotational adjustment, in this embodiment, the outer surfaces of the inner frame 14 are made of flexible rubber. This rubber structure has good elasticity and deformation capacity, allowing the inner frame 14 to smoothly deform to adapt to the rotational movement when rotating inside the outer frame 1, avoiding interference or jamming caused by rigid contact. Furthermore, when the inner frame 14 and the outer frame 1 are horizontally aligned, the flexible rubber automatically fills the gap between the outer side of the inner frame 14 and the inner wall of the outer frame 1, forming a good seal and preventing impurities from leaking through the gap during salvage or transfer.

[0035] Furthermore, multiple sets of slots 21 are provided on the surface of both the outer frame 1 and the inner frame 14. Multiple sets of plates 22 are fixedly connected to the mesh openings of the mesh bag 2 and the straight mesh 3. The slots 21 and plates 22 correspond one-to-one, and the slots 21 and the corresponding plates 22 engage with each other.

[0036] In this embodiment, the slot 21 has a guide ramp and a limiting step inside; the locking plate 22 is a protruding structure with a certain elasticity, its shape is adapted to the slot 21, and its surface has a chamfer that cooperates with the guide ramp. During assembly and disassembly, the installer aligns the locking plate 22 with the slot 21 and presses it in vertically. During the pressing process, the locking plate 22 undergoes elastic deformation, slides into the slot along the guide ramp, and returns to its original shape after entering, being locked by the limiting step to achieve a stable connection; during disassembly, the net bag 2 or the straight net 3 is pulled outward, and the locking plate 22 undergoes elastic deformation again to detach from the slot 21, completing the disassembly. This structure, through elastic deformation and limiting cooperation, achieves quick assembly and disassembly without tools, with a firm connection, simple operation, and good reusability.

[0037] Furthermore, a guide sleeve 20 is fixedly connected to the lower surface of the box body 4. A strap 5, which is double-stranded, passes through the guide sleeve 20. One side of the strap 5 is arranged around the outside of the mesh bag 2. An annular plate 8 is movably fitted onto the outer surface of the tube body 6. Both ends of the strap 5 are fixedly connected to the annular plate 8. A telescopic plate 9 is fixedly connected to the surface of the annular plate 8. One end of the telescopic plate 9 slides through the slide block 10. The end of the telescopic plate 9 located inside the slide block 10 is L-shaped. A third spring 17 is fixedly connected between the inner wall of the slide block 10 and the telescopic plate 9.

[0038] In this embodiment, when using the net bag 2 for retrieval, the net bag 2 can be tightened with the strap 5 as needed to prevent internal impurities from slipping out.

[0039] Specifically, when the straight mesh 3 is inside the outer frame 1, the strap 5 is relaxed; when the straight mesh 3 is inside the box 4, the strap 5 tightens the net bag 2. When it is necessary to loosen the strap 5, the telescopic plate 9 is moved towards one side of the box 4. At this time, the third spring 17 is stretched, and the movement of the telescopic plate 9 causes the annular plate 8 to move along the tube 6, thereby moving both ends of the strap 5 towards the box 4, so that the strap 5 gradually changes from a taut state to a relaxed state, and the net bag 2 returns to its naturally open state, facilitating unloading or continued retrieval. After the operation is completed, the telescopic plate 9 is released, and the third spring 17 pushes the telescopic plate 9 and the annular plate 8 back to their original positions under the action of the restoring force, re-tightening the net bag 2. This structure, through the cooperation of the telescopic plate 9 and the third spring 17, realizes the rapid switching of the strap 5 between tension and relaxation, which is simple to operate, responds quickly, and is suitable for the net control needs in different retrieval scenarios.
