Description

Technical Field

[0001] This utility model relates to the field of fishing tackle landing net connector technology, specifically an anti-rotation assembly. Background Technology

[0002] A landing net is an essential tool for catching hooked fish when fishing. It typically consists of three parts: a net bag, a net ring, and a handle. Its core function is to securely catch the fish when it is pulled to the shore by the fishing line, preventing it from struggling and becoming detached or the line from breaking. Modern landing nets can be categorized by purpose, such as crucian carp landing nets (fine mesh), carp landing nets (deep-net design), and lure landing nets (bite-resistant material). The net bag is usually made of nylon line or PE woven mesh, which is flexible and tear-resistant. The connector is a key component of the landing net, mainly used to allow for a detachable connection between the net ring and the handle.

[0003] Existing landing net connectors mostly use threaded connections or simple snap-fit ​​structures, which have the following drawbacks: First, they are inefficient to assemble and disassemble, as threaded connections require multiple rotations, which is extremely inconvenient in fishing scenarios where landing nets are frequently changed. Second, they have weak anti-rotation capabilities, as ordinary snap-fit ​​structures are prone to circumferential loosening due to external impacts (such as the rotational force of water flow), affecting the stability of the landing net. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an anti-rotation head assembly to solve the problems mentioned in the background art, such as low assembly and disassembly efficiency and weak anti-rotation capability of existing fishing net connectors.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-rotation assembly, comprising a tail screw and a connector, wherein the end of the tail screw is threadedly connected to a connecting body, the inner cavity of the tail screw is provided with a first spring and a piston pad, the end of the connector is provided with a thin shaft, the connecting body has a square hole radially formed, the inside of the square hole is provided with a button and a second spring, the connecting body has a first axial hole axially formed, and the end of the connecting body away from the tail screw has a threaded hole, the inside of the threaded hole is threadedly connected with a set screw.

[0006] Preferably, the piston pad is disposed at the end of the first spring, and the button is disposed at the end of the second spring.

[0007] Preferably, the outer surface of the thin shaft is provided with a first boss, the inside of the button is provided with a second axial hole, and the inside of the second axial hole is provided with a second boss.

[0008] Preferably, the connector is located at the end of the connecting body away from the tail wire, and the thin shaft passes through the first axial hole and the second axial hole.

[0009] Preferably, the two ends of the first axial hole extend to the two ends of the connecting body, and the inner cavity of the tail wire is aligned with the first axial hole.

[0010] Preferably, the end of the threaded hole away from the end face of the connecting body extends into a square hole, and the end of the set screw extends into a U-shaped groove on the outer surface of the button. Beneficial effects

[0011] This utility model provides an anti-rotation assembly. It has the following beneficial effects:

[0012] This anti-rotation assembly achieves both quick assembly / disassembly and anti-rotation functions through the cooperation of the tail screw, connector, and connecting body. When inserted, the inclined surface of the thin shaft boss automatically compresses the button spring to lock it in place. Pressing the button triggers the spring force to automatically push out the connector, allowing for separation with one hand, thus improving assembly / disassembly efficiency. The vertical end face of the thin shaft boss meshes with the vertical end face of the button boss, combined with the square hole constraint of the connecting body, completely restricting circumferential rotation, enhancing anti-rotation reliability, and significantly improving the stability and operational efficiency of the net connection.

[0016] 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.

[0017] like Figure 1-2As shown, this utility model provides an anti-rotation assembly, including a tail screw 1 and a connector 2. The end of the tail screw 1 is threadedly connected to a connecting body 3. The inner cavity of the tail screw 1 is provided with a first spring 4 and a piston pad 5. The end of the connector 2 is provided with a thin shaft 6. The connecting body 3 has a square hole 8 radially. A button 9 and a second spring 10 are provided inside the square hole 8. The connecting body 3 has a first axial hole 11 axially. The end of the connecting body 3 away from the tail screw 1 has a threaded hole 14. A set screw 15 is threadedly connected inside the threaded hole 14.

[0018] Specifically, the piston pad 5 is located at the end of the first spring 4, and the button 9 is located at the end of the second spring 10.

[0019] Specifically, the outer surface of the thin shaft 6 is provided with a first boss 7, the inside of the button 9 is provided with a second axial hole 12, and the inside of the second axial hole 12 is provided with a second boss 13.

[0020] Specifically, the connector 2 is located at the end of the connecting body 3 away from the tail wire 1, and the thin shaft 6 passes through the first axial hole 11 and the second axial hole 12.

[0021] Specifically, the two ends of the first axial hole 11 extend to the two ends of the connecting body 3, and the inner cavity of the tail wire 1 is aligned with the first axial hole 11.

[0022] Specifically, the end of the threaded hole 14 away from the end face of the connecting body 3 extends to the square hole 8, and the end of the set screw 15 extends to the U-shaped groove on the outer surface of the button 9.

[0023] The working principle of the above embodiments:

[0024] The connector 2 is fixed to the net by a threaded connection, and the tail screw 1 is fixed to the net rod connector by a threaded connection. During assembly, the first spring 4 and the piston pad 5 are placed in sequence inside the tail screw 1, and then the tail screw 1 is threaded to the connecting body 3 to seal the inner cavity. The second spring 10 and the button 9 are installed in the radial square hole 8 of the connecting body 3. The end face of the connecting body 3 is provided with a threaded hole 14 6.5 mm from the center. The set screw 15 is screwed into it and into the U-shaped groove of the button 9, so that the button 9 slides radially along the square hole 8 with the connecting body 3 as the reference, and its stroke is controlled by the U-shaped groove on the button 9. This constrains the tail screw 1, the first spring 4, the piston pad 5, the button 9 and the connecting body 3 into a whole. When combined, the thin shaft 6 of the connector 2 is inserted into the axial hole formed by the combination of the first axial hole 11 in the connecting body 3 and the second axial hole 12 in the button 9. During the insertion process, the first boss on the thin shaft 6 of the connector 2 The inclined surface of 7 contacts the inclined surface of the second protrusion 13 inside the button 9. The button 9 is forced to move downward along the square hole 8 to compress the second spring 10. When the first protrusion 7 on the thin shaft 6 of the connector 2 passes the second protrusion 13 inside the button 9, the button 9 is lifted by the second spring 10 and stuck in the groove after the first protrusion 7. At this time, the thin shaft 6 compresses the first spring 4 through the piston pad 5, so that the connector 2 is subjected to the axial reaction force of the first spring 4, and the axial vertical end face of the protrusion on the connector 2 is stuck on the vertical end face of the protrusion of the button 9 and remains stationary. At this time, the square anti-radial rotation protrusion of the connector 2 and the square cavity of the connecting body 3 form a fit, thereby achieving axial and radial fixation. When separating, the button 9 is pressed, and the vertical end face of the protrusion of the connector 2 is released from contact with the vertical end face of the protrusion of the button 9. The end face of the thin shaft 6 of the connector 2 is subjected to the elastic force of the first spring 4 to push the connector 2 out of the axial center hole of the connecting body 3, and the separation is successful.
