[0002] As an important tool in fishery production, the scientific and reasonable use and maintenance of the landing net have important practical significance for improving fishing efficiency and protecting fish resources, and can help fishermen or anglers select a more suitable landing net, so as to achieve accurate and efficient fishing operations.

[0003] The structure of the landing net generally consists of a net pocket, a frame and a handle. In order to facilitate the storage of the landing net, the frame and the handle of the landing net are generally connected by a detachable connection. The common detachable connection methods are thread or simple snap methods. However, after long-term use, the thread connection and the snap are prone to loosen and rotate during the use of the landing net, resulting in the net pocket being prone to deflect relative to the handle during use, resulting in the net pocket of the landing net being prone to unstable support and also affecting the overall use stability of the landing net.

Detailed implementation manners

[0044] The technical solutions in the present utility model will be further described below with reference to the drawings and embodiments.

[0045] Embodiment 1

[0046] This embodiment is basically as Figure 1 、 Figure 2 and Figure 3As shown in the figure, an embodiment of the present utility model provides an internally rotatable connector, which includes a netting connector 10, a handle connector 20, an anti-rotation member 301, a connecting column 401, a connecting sleeve 50, and an anti-rotation groove 302 for the anti-rotation protrusion 601 to be embedded. The netting connector 10 is located at the upper end, and the handle connector 20 is located at the lower end. A first mounting hole 101 for connecting with the netting by screws is arranged radially at the upper end of the netting connector 10; a second mounting hole 201 for inserting the handle is coaxially arranged at the lower end of the handle connector 20.

[0047] As Figure 2 and 3 shown, the connecting column 401 is cylindrical, and the lower end of the netting connector 10 is integrally formed coaxially with the connecting column 401. An embedding groove 402 for the connecting column 401 to be embedded is arranged on the end face of the handle connector 20.

[0048] As Figure 2 shown, a flange 102 that can abut against the upper end of the connecting sleeve 50 is arranged on the outer wall of the lower end of the netting connector 10. An external thread 502 is arranged on the outer wall of the handle connector 20, and an internal thread 501 that meshes with the external thread 502 is arranged on the inner wall of the connecting sleeve 50.

[0049] As Figure 2 and 3 shown, the anti-rotation member 301 is in the shape of a keyway. The lower end contour surface of the anti-rotation member 301 gradually converges and decreases, and the side wall of the anti-rotation member 301 is arc-shaped; the anti-rotation groove 302 is located at the bottom of the embedding groove 402 of the handle connector 20, and the anti-rotation groove 302 can abut against the outer wall of the anti-rotation member 301; when the connecting sleeve 50 abuts against the lower end of the handle connector 20, the anti-rotation groove 302 abuts against the anti-rotation member 301 and locks.

[0050] When using and connecting the internally rotatable connector in this embodiment, first insert the connecting column 401 into the embedding groove 402, and at the same time rotate the netting connector 10 or the handle connector 20 so that the anti-rotation groove 302 and the anti-rotation member 301 are accurately opposite. The anti-rotation member 301 is embedded into the anti-rotation groove 302, and then screw the connecting sleeve 50 so that the internal thread 501 on the connecting sleeve 50 meshes with the external thread 502 on the handle connector 20. When the lower end of the connecting sleeve 50 abuts tightly against the handle connector 20 and the internal thread 501 and the external thread 502 are completely meshed, the anti-rotation member 301 abuts tightly against the anti-rotation groove 302, realizing the quick locking and installation of the internally rotatable connector.

[0051] After the internal rotation connector is installed and connected in place, the connection sleeve 50 covers the connection part of the netting connector 10 and the handle connector 20, and covers the external thread 502 on the handle connector 20, making the whole internal rotation connector more concise and beautiful; when the internal rotation connector is in use, the connection sleeve 50 can provide reliable axial and radial connections for the netting connector 10 and the handle connector 20; the anti-rotation part 301 can cooperate with the anti-rotation groove 302 to prevent relative rotation between the netting connector 10 and the handle connector 20, and can improve the connection stability of the internal rotation connector; at the same time, when disassembling and assembling the internal rotation connector, only need to screw the connection sleeve 50 and slightly adjust the coincidence degree between the anti-rotation part 301 and the anti-rotation groove 302, and the disassembly and assembly of the internal rotation connector are convenient and reliable.

[0052] Embodiment 2

[0053] The difference between Embodiment 2 and Embodiment 1 is basically as shown in the appendix Figure 4 and 5 shown, a kind of internal rotation connector is provided, the anti-rotation protrusion 601 is in the shape of a trapezoidal arc sheet, the anti-rotation protrusion 601 is integrally formed at the upper edge of the handle connector 20, and the outer wall of the anti-rotation protrusion 601 is integrally formed with the outer wall of the handle connector 20; the anti-rotation groove 302 is located at the connection transition of the outer wall of the netting connector 10, the connection column 401 and the flange 102; the number of the anti-rotation protrusion 601 and the anti-rotation groove 302 is two, and the two anti-rotation protrusions 601 are arranged oppositely, and the anti-rotation groove 302 penetrates through the middle part of the flange 102.

[0054] When installing the internal rotation connector in this embodiment, first preliminarily insert the connection column 401 into the embedding groove 402 to realize the preliminary limit of the netting connector 10 and the handle connector 20, then rotate the netting connector 10 and the handle connector 20 so that the two anti-rotation protrusions 601 are aligned with the two anti-rotation grooves 302, and continue to push the netting connector 10 and the handle connector 20 closer to each other so that the two anti-rotation protrusions 601 are respectively embedded into the two anti-rotation grooves 302, and then screw the connection sleeve 50 so that the internal thread 501 on the connection sleeve 50 meshes with the external thread 502 on the handle connector 20.

[0055] In this process, it can be observed from the outer walls of the netting connector 10 and the handle connector 20 whether the two anti-rotation protrusions 601 are aligned with the two anti-rotation grooves 302, making the alignment operation of the two anti-rotation protrusions 601 and the two anti-rotation grooves 302 simpler and more reliable and more convenient for installation; at the same time, the two anti-rotation protrusions 601 and the two anti-rotation grooves 302 can perform more stable anti-rotation treatment in the circumferential direction of the netting connector 10 and the handle connector 20, and the thickness and structure of the anti-rotation protrusion 601 are relatively large, making the connection support between the netting connector 10 and the handle connector 20 more stable.

[0056] Embodiment 3

[0057] The difference between Example 3 and Example 2 is basically as shown in the appendix Figure 6 and 7 shown. A rotary connection head is provided, including that the cross-sectional profile of the connecting column 401 is in the shape of a keyway-like runway, and the upper edge of the slot 402 of the handle connection head 20 is in an arc shape; the anti-rotation part 301 is integrally formed with the lower end of the connecting column 401, and the lower end of the anti-rotation part 301 is in a transverse convex shape.

[0058] When the rotary connection head in this embodiment is installed, the runway-shaped connecting column 401 cooperates with the slot 402. When the net connecting head 10 and the handle connection head 20 are initially installed with the connecting column 401 and the slot 402, the circumferential positioning of the net connecting head 10 and the handle connection head 20 can be carried out. At the same time, during use, it can also play an anti-rotation effect, and at the same time, it can cooperate with the anti-rotation part 301 and the anti-rotation groove 302 to improve the anti-rotation ability.

[0059] Example 4

[0060] The difference between Example 4 and Example 1 is basically as shown in the appendix Figure 8 and 9 shown. A rotary connection head is provided, including a plug 603 and a nut 604. An external thread 502 is provided on the outer wall of the handle connection head 20, and no external thread 502 is provided on the outer wall of the net connecting head 10. The external thread 502 is threadedly connected with the nut 604; no internal thread 501 is provided on the inner wall of the connecting sleeve 50.

[0061] As Figure 8 and 9 shown, the anti-rotation part 301 is a sheet-like protrusion 605, and the anti-rotation groove 302 is a sheet-like groove 606 for the plug 603 to be embedded; a first arc surface 608 is provided at the end of the net connecting head 10, and a second arc surface 607 that fits the first arc surface 608 is provided at the end of the handle connection head 20. The first arc surface 608 and the second arc surface 607 are not simultaneously located on the end surface of the net connecting head 10. The sheet-like protrusion 605 is integrally formed at the middle of the second arc surface 607 of the handle connection head 20, and the anti-rotation groove 302 is located at the middle of the first arc surface 608 at the end of the net connecting head 10.

[0062] As Figure 8 shown, a sliding groove 602 for the plug 603 to slide axially along the net connecting head 10 is penetrated radially through the net connecting head 10. A jack 503 for the plug 603 to pass through is provided on the side wall of the connecting sleeve 50. The connecting sleeve 50 is slidably connected to the outer wall of the net connecting head 10 or the handle connection head 20. The connecting sleeve 50 can cover the sheet-like protrusion 605, the sheet-like groove 606, the first arc surface 608 and the second arc surface 607; the nut 604 can be fixedly abutted against the lower end of the connecting sleeve 50.

[0063] When installing the internal rotation connector in this embodiment, first screw the nut 604 downwards. At this time, the connecting sleeve 50 drives the pin 603 to move downwards along the sliding groove 602, so that the second arc surface 607 at the upper end of the handle connector 20 is exposed. Then tilt the end of the first arc surface 608 of the net connecting head 10, so that the buckle on the first arc surface 608 fits onto the second arc surface 607, realizing the preliminary locking of the net connecting head 10 and the handle connector 20. At the same time, the sheet-like protrusion 605 is embedded into the sheet-like groove 606. After the sheet-like protrusion 605 and the sheet-like groove 606 cooperate, they have a good anti-rotation effect. Then screw the nut 604 upwards again, pushing the connecting sleeve 50 to drive the pin 603 to move upwards along the sliding groove 602. When the pin 603 moves to the top of the sliding groove 602, the upper end of the connecting sleeve 50 also synchronously covers the sheet-like protrusion 605, the sheet-like groove 606, the first arc surface 608 and the second arc surface 607, realizing the locking of the net connecting head 10 and the handle connector 20.

[0064] During this process, the locking of the net connecting head 10 and the handle connector 20 can be realized by adjusting and screwing the nut 604. The connection locking control of the net connecting head 10 and the handle connector 20 is simpler. At the same time, the pin 603 cooperates with the connecting sleeve 50, and can further lock the net connecting head 10 and the handle connector 20 radially, making the connection between the net connecting head 10 and the handle connector 20 more stable.

[0065] Embodiment 5

[0066] The difference between Embodiment 5 and Embodiment 4 is basically as shown in the appendix Figure 10 and 11 shown. A kind of internal rotation connector is provided, which further includes a spring 609. The external thread 502 is located on the outer wall of the net connecting head 10, and the external thread 502 is not provided on the outer wall of the handle connector 20. The nut 604 is threadedly connected to the external thread 502 on the net connecting head 10, and the nut 604 and the connecting sleeve 50 can cover the threads on the outer walls of the net connecting head 10 and the handle connector 20.

[0067] As Figure 11 shown, the sliding groove 602 horizontally penetrates through the handle connector 20. The spring 609 is coaxially sleeved between the net connecting head 10 and the connecting sleeve 50. The upper end of the spring 609 abuts against the two end parts of the pin 603, and the lower end of the spring 609 abuts against the lower end of the handle connector 20. The upper end of the connecting sleeve 50 can abut against the nut 604.

[0068] As Figure 11As shown in the figure, two first arc surfaces 608 are provided on the left and right sides of the lower end of the net scooping connector 10. The two first arc surfaces 608 make the lower end of the net scooping connector 10 form a similar structure to the anti-rotation part 301 and the connecting column 401. Two second arc surfaces 607 that fit with the first arc surfaces 608 are provided on the upper end part of the handle connector 20. The two second arc surfaces 607 make the upper end of the handle connector 20 form a similar structure to the anti-rotation groove 302 and the embedding groove 402.

[0069] When installing an in-rotation connector in this embodiment, slide the connecting sleeve 50 downward. The connecting sleeve 50 drives the pin 603 to compress the spring 609. At this time, the pin 603 moves downward along the sliding groove 602, so that the second arc surface 607 of the handle connector 20 is exposed. At this time, horizontally embed the first arc surface 608 of the net scooping connector 10 into the second arc surface 607. The first arc surface 608 of the net scooping connector 10 abuts and locks with the second arc surface 607 of the handle connector 20. At this time, loosen the connecting sleeve 50. Under the action of the spring 609, the spring 609 pushes the connecting sleeve 50 to move back along the sliding groove 602 to the top of the sliding groove 602 through the pin 603, and the top end of the connecting sleeve 50 abuts against the end face of the nut 604, realizing the quick snap-in installation of the net scooping connector 10 and the handle connector 20. And the net scooping connector 10 and the handle connector 20 still play a role of anti-rotation and stable support under the cooperation of the first arc surface 608 and the second arc surface 607.

[0070] After the above process, the connecting sleeve 50 and the nut 604 integrally cover the first arc surface 608 and the second arc surface 607 of the net scooping connector 10 and the handle connector 20, realizing the limit of the connection part of the net scooping connector 10 and the handle connector 20, and at the same time improving the aesthetic degree of the connection part of the net scooping connector 10 and the handle connector 20.
