Detailed implementation manners

[0019] The following combines the attached drawings and embodiments to further describe in detail the specific implementation manners of the present utility model. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0020] As Figures 1 to 6 shown, a net head anti-random rotation mechanism for a fishing landing net of the present utility model includes a first installation pipe 1, a second installation pipe 2 and a net head bolt 3. The inner side wall of one end of the first installation pipe 1 is provided with internal threads, one end of the second installation pipe 2 is provided with an installation ring 4, the outer side wall of the installation ring 4 is provided with external threads, and the first installation pipe 1 is threadedly connected to the second installation pipe 2 through the installation ring 4. It also includes a polygonal limiting ring 5. One end of the polygonal limiting ring 5 is provided with a locking ring 6. The locking ring 6 is set as multiple locking pieces, and buffer seams are arranged between adjacent locking pieces. The inner side wall of the locking ring 6 formed by multiple locking pieces is provided with internal threads. The other end of the second installation pipe 2 is provided with a frustum-shaped tightening pipe 7. The inner part of the second installation pipe 2 close to the installation ring 4 is provided with a pressing ring 8. The inner side wall of the second installation pipe 2 adjacent to the pressing ring 8 is provided with a polygonal groove 9. The polygonal groove 9 is slidably clamped with the polygonal limiting ring 5. An elastic component 10 is sleeved outside multiple locking pieces. Multiple groups of locking pieces and the elastic component 10 are all located inside the second installation pipe 2. Multiple groups of locking pieces are squeezed by the inner side wall of the tightening pipe 7 and contract and deform inward. The net head bolt 3 passes through the tightening pipe 7 and is threadedly connected to multiple locking pieces;

[0021] When using the above-mentioned net head anti-random rotation mechanism of the fishing landing net, the user inserts the net head bolt of the net head into the tightening pipe and rotates it. At this time, the net head bolt will rotate into multiple locking pieces of the locking ring. As the net head bolt rotates and the net head abuts against the tightening pipe, when the net head bolt continues to rotate, the net head bolt no longer moves relative to the tightening pipe. At this time, the locking ring will squeeze the elastic component and move towards the tightening pipe. At this time, multiple locking pieces are squeezed by the tightening pipe and move closer to the net head bolt, making the thread engagement between the net head bolt and multiple locking pieces deeper. Until the net head bolt is rotated and tightened, under the dual action of the thread friction force and the squeezing force of multiple locking pieces, the net head bolt is limited in this state and cannot rotate by itself. Moreover, through the cooperation of the spring, the tightening pipe, the polygonal limiting ring and multiple groups of locking pieces, the locking force of the landing net can be flexibly adjusted. This anti-random rotation mechanism greatly improves the stability and convenience during the use of the net head.

[0022] Preferably, as an embodiment above, the elastic component 10 is preferably set as a spring;

[0023] As a mature elastic element, the spring's fast response ability ensures the immediate reaction of the locking ring during operation. At the same time, the reliability of the spring enhances the stability and durability of the entire mechanism. Moreover, the elastic component is not limited to the spring only, and other elastic materials that can be assembled on multiple locking pieces can also be selected.

[0024] Preferably, as an embodiment above, auxiliary sliding rods 11 are provided at both the top and bottom of the polygonal limiting ring 5. The auxiliary sliding rods 11 all extend towards the locking ring 6. U-shaped sliding grooves 12 are provided at both the top and bottom of the polygonal groove 9, and the U-shaped sliding grooves 12 extend towards the tightening tube 7 inside the second installation tube 2. The two auxiliary sliding rods 11 are respectively slidably clamped with the two U-shaped sliding grooves 12;

[0025] During the process of assembling the polygonal limiting ring into the polygonal groove, due to the pushing action of the elastic component, the polygonal limiting ring cannot be directly placed into the polygonal groove. Therefore, when tightening the pressing ring, if the polygonal limiting ring is not correctly aligned in the polygonal groove, the polygonal limiting ring cannot be used properly. Through the design of the present invention, before the polygonal limiting ring slides into the polygonal groove, the two auxiliary sliding rods can be respectively slid into the two U-shaped sliding grooves. At this time, although the polygonal limiting ring has not yet slid into the polygonal groove, the cooperation between the two auxiliary sliding rods and the two U-shaped sliding grooves has limited the polygonal limiting ring, so that when tightening the pressing ring, the polygonal limiting ring can smoothly slide into the polygonal groove.

[0026] Furthermore, with the guiding action of the auxiliary sliding rod and the U-shaped sliding groove, it is ensured that the polygonal limiting ring will not undergo unnecessary displacement when subjected to external forces, guaranteeing the overall accuracy of the mechanism and the reliability of long-term operation.

[0027] Preferably, as an embodiment above, an external thread is provided on the outer sidewall of the pressing ring 8. An operating ring 13 is provided on the side of the pressing ring 8 close to the first installation tube 1. An internal thread is provided on the inner sidewall of the second installation tube 2 adjacent to the polygonal groove 9. The pressing ring 8 is threadedly connected to the second installation tube 2, and the pressing ring 8 limits the polygonal limiting ring 5 in the polygonal groove 9;

[0028] The threaded connection between the pressing ring and the second installation tube makes the installation process more efficient and convenient.

[0029] Preferably, as an embodiment above, auxiliary blocks 14 are provided at both the top and bottom of one end of the operating ring 13 of the pressing ring 8;

[0030] The installation process of the pressing ring is to insert a finger into the pressing ring and rotate the pressing ring to install it in the second installation pipe. Since the frictional force between the finger and the pressing ring cannot reliably lock the pressing ring, two groups of auxiliary blocks can be rotated by the finger or other tools at this time to lock the pressing ring, making the locking of the pressing ring more secure and greatly improving the operation convenience and reliability.

[0031] As a preference of the above embodiment, multiple groups of anti-slip grooves 15 are provided on the outer circumferential side walls of the first installation pipe 1 and the second installation pipe 2;

[0032] The addition of the anti-slip grooves ensures that the operator can firmly hold the landing net under various environmental conditions, preventing accidents caused by slippery hands and enhancing the safety of using the landing net.

[0033] A net head anti-random rotation mechanism for a fishing landing net and its working principle. When using the net head anti-random rotation mechanism of the above fishing landing net, the user inserts the net head bolt of the net head into the tightening pipe and rotates it. At this time, the net head bolt will rotate into the multiple locking pieces of the locking ring. As the net head bolt rotates and the net head abuts against the tightening pipe, continue to rotate the net head bolt. At this time, the net head bolt no longer moves relative to the tightening pipe. At this time, the locking ring will squeeze the elastic component to move towards the tightening pipe. At this time, the multiple locking pieces are squeezed by the tightening pipe and move closer to the net head bolt, making the thread engagement between the net head bolt and the multiple locking pieces deeper. Until the net head bolt is rotated tightly, under the dual action of the thread frictional force and the squeezing force of the multiple locking pieces, the net head bolt is limited in this state and cannot rotate by itself. Moreover, through the cooperation of the spring, the tightening pipe, the polygonal limiting ring and multiple groups of locking pieces, the locking force of the landing net can be flexibly adjusted.

[0035] In the present utility model, the "first", "second", "third" do not represent specific quantities and sequences, but are only used for name distinction.

[0036] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present utility model, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
