Description

Technical Field

[0001] This utility model relates to the technical field of fishing gear, and in particular to a self-locking anti-detachment fishing rod. Background Technology

[0002] Fishing, a popular recreational sport, is largely characterized by its core equipment: the fishing rod, which is typically a multi-section, plug-in structure for easy carrying and storage. Currently, the connection between the sections of common plug-in fishing rods relies primarily on the interference fit friction between adjacent sections. This connection method has significant drawbacks: First, during use, especially when hooking a fish or snagging the bottom and forcefully lifting the rod, the sections may rotate and loosen due to the immense axial tension, leading to "section breakage" or "disconnection." This not only affects operation but may even damage the rod or cause the catch to escape. Second, to obtain sufficient friction, the joints between the sections usually need to be manufactured with great precision, requiring advanced production processes and increasing manufacturing costs. Furthermore, frequent plugging and unplugging and friction can easily wear down the joints, shortening the rod's lifespan.

[0003] A search revealed an existing patent (publication number: CN222442826U) that discloses a fishing rod. This fishing rod includes a rod body, a reel seat clip, and a handle. The reel seat clip includes a reel seat body, a fixed clip, and a sliding clip. The front end of the reel seat body is connected to the fixed clip, and the front end of the reel seat body is connected to the rod body. The handle is characterized by its fixed or rotatable connection to the sliding clip at the front end. A protective cover is fitted over the outer side of the reel seat body, and the cover has a window for the fishing line to engage. The handle drives the sliding clip through the rear end of the cover and inserts it into the cover, where it is fixedly connected to the rear end of the reel seat body. This design offers advantages such as simple structure, comfortable grip, good overall integrity, high stability, and high fishing line engagement strength.

[0004] However, in the above-mentioned scheme, during use, especially under strong tension or frequent shaking, this connection may not provide sufficient stability and security, thus affecting the fixed connection effect of the fishing rod. This situation may cause the fishing rod to loosen in actual use, thereby affecting the fishing experience and results. Utility Model Content

[0005] In view of the aforementioned problems that existing technologies cannot provide sufficient stability and security, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a self-locking anti-detachment fishing rod, which aims to generate a strong radial locking force through mechanical extrusion, effectively resisting the huge pulling force during use.

[0007] To solve the above technical problems, this utility model provides the following technical solution: a self-locking anti-detachment fishing rod, including a handle, the handle having multiple rod bodies connected by a plug-in method inside, and a locking sleeve that can slide axially on the outer side of the root of the last section of the rod body, the inner wall of the locking sleeve and the outer wall of the rod body forming an annular cavity; The annular cavity is provided with a locking ring made of elastic material; The inner wall of the locking sleeve is provided with a conical extrusion groove protruding towards its axis. When the locking sleeve slides toward the rod tip, the conical extrusion groove can squeeze the locking ring, causing it to contract radially and hold the adjacent rod body to which it is inserted.

[0008] As a preferred embodiment of the self-locking anti-detachment fishing rod of this utility model, the taper of the conical extrusion groove is in the range of 5°~45°.

[0009] As a preferred embodiment of the self-locking anti-detachment fishing rod of this utility model, the locking sleeve is provided with a limiting structure to restrict its sliding range. The limiting structure includes an annular protrusion on the inner wall of the locking sleeve and a groove on the outer wall of another section of the rod that cooperates with the annular protrusion.

[0010] As a preferred embodiment of the self-locking anti-detachment fishing rod of this utility model, the outer surface of the locking sleeve is provided with anti-slip texture.

[0011] As a preferred embodiment of the self-locking anti-detachment fishing rod of this utility model, the cross-section of the locking ring is circular, rectangular or trapezoidal.

[0012] As a preferred embodiment of the self-locking anti-detachment fishing rod of this utility model, the locking ring is made of rubber, silicone or polyurethane elastomer material.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects: 1. This utility model generates a strong radial locking force through mechanical extrusion, which can effectively resist the huge tensile force during use, effectively avoid the "joint breakage" phenomenon, and greatly improve the stability and safety of this fishing rod.

[0014] 2. This utility model only adds a locking sleeve and a locking ring to the existing fishing rod structure, which makes the structure compact, hardly changes the original appearance and center of gravity of the fishing rod, and is simple in structure, easy to use and maintain.

[0015] 3. This utility model is easy to operate; it locks with a push and opens with a pull. The operation is intuitive and simple, requiring no tools. Attached Figure Description

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Example 1 Reference Figures 1-3 This is the first embodiment of the present invention, which provides a self-locking anti-detachment fishing rod.

[0020] Includes a handle 1, inside which are provided multiple rod bodies 2 connected by a plug-in method. The outer side of the root of the last section of the rod body 2 is fitted with a locking sleeve 3 that can slide axially. An annular cavity is formed between the inner wall of the locking sleeve 3 and the outer wall of the rod body 2. The locking function is modularly integrated into the last section of the rod. The design of the sliding sleeve and the annular cavity provides a structural basis and operating space for the subsequent elastic locking mechanism, enabling the locking action while ensuring the overall simplicity and aesthetics of the fishing rod. A locking ring 4 made of elastic material is provided inside the annular cavity; The locking ring 4 can undergo controllable elastic deformation under external force to achieve locking, and can automatically return to its original shape after the external force is removed to achieve unlocking. It realizes the core functions of "self-locking" and "anti-loosening" without the need for additional tools and can be repeatedly operated, ensuring the convenience and reliability of use. The inner wall of the locking sleeve 3 is provided with a conical extrusion groove 6 that protrudes toward its axis. When the locking sleeve 3 slides toward the rod tip, the conical extrusion groove 6 can extrude the locking ring 4, causing it to contract radially and hold the adjacent rod body 2 that it is inserted with. It can smoothly and efficiently convert the linear thrust applied by the user to the locking sleeve into radial compressive force on the locking ring, forming a highly efficient "inclined" mechanical mechanism. This allows a large radial locking force to be generated with a small axial force, making operation effortless and the locking effect significant.

[0021] The taper of the conical extrusion groove 6 ranges from 5° to 45°; This ensures that the locking operation achieves the best balance between effort-saving operation, stroke length, and self-locking reliability.

[0022] The locking sleeve 3 is provided with a limiting structure to restrict its sliding range. The limiting structure includes an annular protrusion 8 on the inner wall of the locking sleeve 3 and a groove 5 on the outer wall of the other rod body 2 that cooperates with the annular protrusion 8. The locking sleeve is clearly defined in two extreme positions: "unlocked" and "locked". This prevents the locking sleeve from sliding too much and detaching from the rod or from moving in the wrong position, which would affect the locking effect. This improves the overall quality of the product and enhances the sense of security and reliability during use. The method of use is clearly defined, and the description of "radial contraction and tightening" emphasizes that the locking force is evenly distributed, the connection is firm and stable, and it can effectively prevent the rod section from accidentally coming apart when under fishing force.

[0023] The outer surface of the locking sleeve 3 is provided with anti-slip texture 7; It significantly increases the friction between the user's fingers and the locking sleeve, ensuring that the operation of pushing and pulling the locking sleeve is easy and non-slip, thus improving the convenience and reliability of operation.

[0024] Example 2 Reference Figures 1-5 This is the second embodiment of the present invention, which differs from the first embodiment in that the cross-section of the locking ring 4 is circular, rectangular or trapezoidal; This increases the flexibility of product design and adaptability to different performance preferences.

[0025] The locking ring 4 is made of rubber, silicone, or polyurethane elastomer material; This ensures that the locking ring has good elasticity and resilience, as well as durability, aging resistance, and water resistance, thus guaranteeing the long-term reliability of the product in complex usage environments.

[0026] Based on embodiments 1-2, the working principle of this utility model is as follows: Insert the thinner section of the adjacent rod body 2 into the interface of the last section of the rod body 2; then, hold the anti-slip texture 7 of the locking sleeve 3 with your fingers and push it towards the rod tip; the locking sleeve 3 moves forward, and its internal conical extrusion groove 6 begins to contact and extrude the locking ring 4; the locking ring 4 is forced to contract radially under the action of the conical surface, tightly hugging the outer wall of the adjacent section of the rod body 2, thereby achieving a firm lock between the two sections of the rod body 2; When you need to reel in the rod, pull the locking sleeve 3 backward toward the handle; the conical compression groove 6 retracts, and the squeezing force on the locking ring 4 disappears; the locking ring 4 returns to its original shape by its own elasticity, expands radially, and loosens its grip on the inner rod body 2; at this time, the two sections of the rod body 2 can be easily pulled out and separated.

[0027] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
