Abstract
Description
Technical Field
[0001] This utility model relates to the field of fishing gear technology, specifically to a connection structure between a landing net pole and a landing net head. Background Technology
[0002] Fishing tackle is a general term for various tools, equipment and auxiliary supplies used in fishing activities, covering a range of products from fishing rods and fishing lines to auxiliary accessories. Among them, landing nets are a type of fishing tackle. They are an important auxiliary tool used to catch fish that have taken the bait during fishing. Landing nets are mainly composed of three parts: landing net pole, net frame and net bag.
[0003] In existing technologies, the landing net pole and the net frame are typically connected by threads. The landing net pole has internal threads at one end, and the net frame has a threaded rod at one end; they are then tightened to secure them together. However, in actual use, when fish struggle inside the net, the net frame experiences unbalanced forces, causing its center of gravity to shift. This leads to the threaded connection gradually loosening, potentially resulting in the unexpected separation of the net frame from the landing net pole, affecting the stability and reliability of the operation. Utility Model Content
[0004] The purpose of this utility model is to provide a connection structure between the net-collecting pole and the net-collecting head, which solves the problem that the existing net frame may experience a shift in center of gravity due to unbalanced force, leading to gradual loosening of the threaded connection and potentially causing the net frame and net-collecting pole to separate unexpectedly.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to a connection structure between a net-collecting pole and a net-collecting head, comprising a hexagonal nut welded to one end of the net frame and a connecting seat disposed at the end of the net-collecting pole. A connecting rod is provided at the end of the connecting seat away from the net-collecting pole. A radially penetrating groove is formed on the circumferential side of the connecting rod. A sleeve is coaxially fitted onto the outside of the connecting rod. The inner wall of the sleeve is formed into an internal hexagonal structure matching the hexagonal nut. A pin slides through the groove, with both ends radially penetrating the side wall of the sleeve and extending outwards. A groove is formed at the end of the sleeve near the connecting seat. A spring is coaxially fitted onto the outside of the connecting rod and accommodated within the groove. One end of the spring abuts against the end face of the connecting seat, and the other end abuts against the side of the pin facing the connecting seat.
[0007] Furthermore, anti-detachment caps are evenly fitted onto both ends of the pin through the sleeve.
[0008] Furthermore, the outer wall of the sleeve is provided with axial anti-slip texture.
[0009] Furthermore, the sleeve is made of aluminum alloy.
[0010] Furthermore, the net-collecting pole, connecting seat, and connecting rod are integrally formed.
[0011] This utility model has the following beneficial effects:
[0012] (1) By holding the sleeve and pulling it towards the net-collecting rod, the sleeve moves axially along the connecting rod. When the sleeve moves, its inner side pushes the pin to slide in the groove of the connecting rod, while compressing the spring between the connecting seat and the pin. At this time, the front end of the sleeve retracts, so that the threaded hole at the front end of the connecting rod is fully exposed. Then, the threaded rod on the net frame is aligned and screwed into the threaded hole at the front end of the connecting rod until the hexagonal nut at the bottom of the threaded rod is tightly abutted against the front end face of the connecting rod. Finally, the sleeve is released, the compressed spring releases its elasticity, and pushes the pin and the sleeve linked with it to slide back to the direction away from the net-collecting rod. After the sleeve is reset, its front end returns to the state of covering the front end of the connecting rod. At the same time, the inner hexagonal structure of the sleeve completely nests and wraps the hexagonal nut. During use, the nested hexagonal nut and the inner hexagonal sleeve effectively prevent the net frame from rotating and loosening relative to the net-collecting rod, thereby preventing the threaded rod from accidentally unscrewing out of the threaded hole and avoiding accidental separation between the net-collecting rod and the net frame.
[0013] (2) When the sleeve of this utility model is pulled or reset, the pin slides in the groove, and the anti-dislodgement cap effectively restricts the axial movement of the pin in the side wall hole of the sleeve by increasing the radial dimension of the pin end, thus preventing the pin from accidentally coming out.
[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0024] Please see Figures 1-5 As shown, this utility model is a connection structure between a net-collecting rod and a net-collecting head, including a hexagonal nut 2 welded to one end of the net frame 1, and a connecting seat 4 set at the end of the net-collecting rod 3. A connecting rod 5 is provided at the end of the connecting seat 4 away from the net-collecting rod 3. A radially through slot 501 is opened on the peripheral side of the connecting rod 5. A sleeve 7 is coaxially sleeved on the outside of the connecting rod 5. The inner wall of the sleeve 7 is formed into an inner hexagonal structure that matches the hexagonal nut 2. A pin 8 is slidably inserted in the slot 501. Its two ends radially penetrate the side wall of the sleeve 7 and extend outward. A groove is opened at the end of the sleeve 7 near the connecting seat 4. A spring 9 is coaxially sleeved on the outside of the connecting rod 5 and accommodated in the groove. One end of the spring 9 abuts against the end face of the connecting seat 4, and the other end abuts against the side of the pin 8 facing the connecting seat 4.
[0025] One end of the mesh frame 1 is provided with a threaded rod 10, a hexagonal nut 2 is welded to the outside of the threaded rod 10, and the end of the connecting rod 5 is provided with a threaded hole, and the threaded rod 10 is threadedly connected to the inside of the threaded hole.
[0026] The inner wall structure of the hexagonal nut 2 and the sleeve 7 is not limited to hexagonal, but can adopt a variety of corresponding polygonal configurations (such as quadrilateral, octagon, etc.) or a straight structure.
[0027] When installing the net-falling pole 3 and the net frame 1, by holding the sleeve 7 and pulling it towards the net-falling pole 3, this action causes the sleeve 7 to move axially along the connecting rod 5. When the sleeve 7 moves, its inner side pushes the pin 8 to slide in the groove 501 of the connecting rod 5, while compressing the spring 9 located between the connecting seat 4 and the pin 8. At this time, the front end of the sleeve 7 (the end away from the net-falling pole 3) retracts backward, so that the threaded hole at the front end of the connecting rod 5 is fully exposed. Then, the threaded rod 10 on the net frame 1 is aligned and screwed into the threaded hole at the front end of the connecting rod 5 until the hexagonal nut 2 at the bottom of the threaded rod 10 is tightly fitted to the front end face of the connecting rod 5. After the sleeve 7 is loosened, the compressed spring 9 releases its elasticity, pushing the pin 8 and the sleeve 7 linked with it to slide back away from the net-collecting rod 3 (i.e., the direction of the net frame 1). After the sleeve 7 is reset, its front end returns to the state of covering the front end of the connecting rod 5. At the same time, the inner hexagonal structure of the sleeve 7 completely nests and wraps the hexagonal nut 2. During use, the nested hexagonal nut 2 and the inner hexagonal sleeve 7 effectively prevent the net frame 1 from rotating and loosening relative to the net-collecting rod 3, thereby preventing the threaded rod 10 from accidentally unscrewing out of the threaded hole and falling off, thus avoiding the separation between the net-collecting rod 3 and the net frame 1.
[0028] When disassembling the net-collecting pole 3 and the net frame 1, by holding the sleeve 7 and pulling it towards the net-collecting pole 3, the sleeve 7 moves axially along the connecting rod 5. When the sleeve 7 moves backward, its inner hexagonal structure disengages from the hexagonal nut 2, releasing the rotational constraint on the nut. At the same time, the spring 9 is compressed. At this time, the hexagonal nut 2 is no longer restricted by the sleeve 7 and can rotate freely. The operator rotates the net frame 1 in the opposite direction, so that the threaded rod 10 exits from the threaded hole of the connecting rod 5. After the thread is completely loosened, the net frame 1 can be separated from the net-collecting pole 3. Finally, the sleeve 7 is released, the spring 9 rebounds, and the sleeve 7 is pushed back to its initial position, ready for the next installation.
[0029] The pin 8 is evenly fitted with anti-detachment caps 6 at both ends of the sleeve 7;
[0030] When the sleeve 7 is pulled or reset, the pin 8 slides in the slot 501, while the anti-dislodgement cap 6 effectively restricts the axial movement of the pin 8 in the side wall hole of the sleeve 7 by increasing the radial dimension of the end of the pin 8, thus preventing the pin 8 from accidentally coming out.
[0031] The outer wall of sleeve 7 is provided with axial anti-slip texture;
[0032] Among them, the axial anti-slip texture design on the outer wall of the sleeve 7 significantly improves the grip stability during operation. During installation or disassembly, when the operator's fingers come into contact with the sleeve 7, these longitudinal grooves can effectively increase the surface friction resistance and prevent the hand from slipping.
[0033] Sleeve 7 is made of aluminum alloy;
[0034] The net-collecting pole 3, the connecting seat 4, and the connecting rod 5 are integrally formed.

Clearly, many modifications and variations can be made based on the content of this specification.
