[0016] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings. The illustrative implementation methods and descriptions of the embodiments of this disclosure are only used to explain the embodiments of this disclosure and are not intended to limit the embodiments of this disclosure.

[0017] like Figure 1 As shown, the insulating operating rod for a power distribution line in this application comprises a combination of multiple components, namely an insulating rod body 1, a telescopic locking mechanism 2, a connector 3, a handle 4, and a stabilizing collar 5. These components, through their rational design and connection, ensure the safety and stability of the overall operating rod under high load conditions.

[0018] The insulating rod 1, as the core component of the overall operating rod, is responsible for providing insulation and mechanical support. It is typically made of high-strength, lightweight materials with good electrical insulation properties, such as glass fiber reinforced plastic. The structure of the insulating rod 1 can be designed as a hollow, multi-segmented, telescopic structure, reducing weight while maintaining strength. Furthermore, its surface can undergo special processing (such as coating with a hydrophobic coating) to enhance its weather resistance and electrical insulation properties.

[0019] The telescopic locking mechanism 2 is located inside the insulating rod body 1 to ensure the multi-section insulating rod body 1 is fixed in the telescopic state and to effectively prevent accidental slippage due to high load. The telescopic locking mechanism 2 includes at least three-stage elastic locking assemblies 211 (see details). Figure 2 This structure uses several pairs of elastic clips and interlocking slots to achieve progressive engagement, thereby enhancing the fixing strength at different positions. To improve the overall load-bearing capacity, the mechanism is made of high-strength alloy materials, such as titanium alloy or aluminum alloy, to meet the high mechanical requirements in complex environments.

[0020] Connector 3 is located at the end of the insulating rod 1 and is used to form a detachable connection with other external tools. Its specific structure may include a design with standardized holes or slots, secured by threads or other reliable fastening methods. For example, when it is necessary to replace the front operating head, the assembly process can be completed by simply rotating connector 3. To ensure connection strength, the body material of connector 3 is usually selected from a metal material with high hardness and corrosion resistance.

[0021] The grip 4 is located at the end of the insulating rod 1 and is mainly for the operator to hold. It is typically connected to the insulating rod 1 internally via a threaded connection, facilitating quick replacement in case of damage. The surface of the grip 4 usually has anti-slip textures or a rubber layer to increase friction between the hand and the grip, while ensuring user comfort and safety during operation. The grip 4 itself can be designed in different shapes (e.g., cylindrical, flat oval, etc.) to accommodate the gripping habits of different people.

[0022] The stabilizing collar 5 is located on the outer part of the middle section of the insulating rod 1. Its function is to increase the balance and stability of the entire rod during operation. Axial positioning between the stabilizing collar 5 and the insulating rod 1 is mainly achieved through friction. This can be optimized by increasing the contact area between the two and adjusting the roughness of the inner diameter of the stabilizing collar 5. Furthermore, if more stringent requirements are imposed for specific working scenarios, a slight elastic pre-compression mechanism can be introduced into the design to further enhance the reliability of the friction force.

[0023] To address the technical challenge of preventing accidental slippage under high load conditions, this application employs an innovative three-stage elastic locking assembly. This assembly effectively disperses and absorbs externally applied forces, preventing instantaneous unlocking due to overload at a specific location. Furthermore, the use of high-strength alloy as the main material provides the entire mechanism with strong load-bearing capacity, maintaining a high degree of robustness even in harsh environments. In summary, this structure, based on the principles of mechanical distribution, minimizes the possibility of operating lever malfunctions through the combined effect of multiple measures, thereby ensuring the personal safety of power workers during actual operations.

[0024] like Figure 2As shown, in one embodiment, the telescopic locking mechanism 2 of the insulating operating rod of a power distribution line of this application includes a three-stage elastic locking assembly 211. Each assembly has a specially configured spring force adjustment device 212. This arrangement allows for flexible adjustment of the locking strength according to the actual usage scenario and ensures that the connection parts at each level can work stably under high load conditions without accidental loosening. Each stage of the elastic locking assembly 211 is installed between the internal cavities of the insulating rod body 1, corresponding to different levels of rod segments, and is fixed and limited by locking grooves or flanges. Furthermore, high-strength alloy materials are used to further enhance durability and impact resistance.

[0025] Specifically, the manual adjustment of the spring preload can be achieved by designing individual adjusting screws on each level of the elastic locking assembly 211. These adjusting screws pass through pre-drilled holes on the insulating rod body 1 and contact the end of the spring for precise adjustment. For example, the first-level locking assembly has a larger spring force to accommodate the thicker main rod section, while the second and subsequent assemblies have progressively smaller adjustment ranges according to the needs of slender rod sections, maintaining overall stable constraint capability to prevent changes in the extension / retraction state due to external tension during operation. The components are assembled using a sliding nesting method, combined with mechanical friction locking to ensure reliability.

[0026] like Figure 2 As shown, in one embodiment, the telescopic locking mechanism 2 of the insulating operating rod of a power distribution line in this application is provided with an auxiliary locking component 24. The auxiliary locking component 24 is located inside the telescopic locking mechanism 2 near the operating end, facilitating manual locking by the operator after mechanical length adjustment. Its structure includes a rotary-triggered connector and a set of cam-type clamping components that cooperate with it. By rotating a specific manual knob, the clamping components can apply radial outward force, thereby creating a strong frictional or biting force between the inner and outer tube walls to fix the rod and prevent any accidental loosening or slippage. Furthermore, the material selection for the auxiliary locking component 24 must consider both wear resistance and high hardness to adapt to repeated use conditions.

[0027] For example, during installation, the auxiliary locking element 24 can be positioned within a designated area of ​​the telescopic locking mechanism 2, ensuring that this position allows the auxiliary locking element 24 to directly contact both the inner and outer parts of the insulating rod 1. Specifically, by rotating the manual knob to a preset angle, the cam assembly presses against the inner or outer surface of the rod, thus keeping them stationary in their relative directions. The entire connection relies on precision manufacturing processes to ensure consistent clearances and compatibility between components.

[0028] like Figure 3As shown, in one embodiment, the insulating rod body 1 of the insulating operating rod of a power distribution line of this application is provided with a positioning slot 11 for installing a telescopic locking mechanism 2. The positioning slot 11 extends axially along the insulating rod body 1 and is precisely machined to ensure a proper fit with the telescopic locking mechanism 2. Specifically, the inner wall of the positioning slot 11 is covered with an anti-corrosion and wear-resistant coating 12. This coating is made of high-performance materials and aims to reduce the risk of component wear and corrosion under prolonged use or high load conditions, thereby extending the overall service life of the operating rod. Optimization of the component contact areas further enhances the reliability and durability of the insulating operating rod.

[0029] For example, a matching positioning groove 11 can be formed inside the insulating rod body 1 using injection molding or machining. Simultaneously, a ceramic composite layer or Teflon material of appropriate thickness can be sprayed onto the inner wall surface to form the anti-corrosion and wear-resistant coating 12. Furthermore, when assembling the telescopic locking mechanism 2 into this groove, good alignment accuracy must be ensured to avoid damage caused by relative movement. This structural design ensures a tight fit between the components, thereby guaranteeing the stable operation of the overall function.

[0030] like Figure 3 As shown, in one embodiment, the handle 4 of an insulating operating rod for a power distribution line of this application is fixedly connected to the insulating rod body 1 by threads. To address the potential loosening of the connection under high load conditions, an additional self-locking nut 41 is added at the threaded connection between the handle 4 and the insulating rod body 1. This self-locking nut 41 is a nut structure with a special wedge-shaped tooth design, installed in the transition area between the handle 4 and the insulating rod body 1, specifically between the end of the thread and the operator's grip area. The self-locking nut 41 itself is made of high-strength engineering material, and its unique design effectively compensates for the expansion of gaps in the threaded pair under high stress conditions. By introducing this additional component, while ensuring the compactness of the threaded connection, the overall mechanical strength is also improved, meeting the usage requirements under different working conditions.

[0031] Specifically, matching threads can be machined on the inner side of the grip 4 and the outer surface of the insulating rod 1 using machining. Then, a pre-made self-locking nut 41 is placed behind the threaded connection, and finally, the components are tightened manually or with tools. For example, a constant tightening torque can be applied using a torque measuring device to ensure that the function of the self-locking nut 41 is fully activated and to verify its installation effect.

[0032] like Figure 3As shown, in one embodiment, the handle 4 of the insulating operating rod for a power distribution line of this application is equipped with an additional safety protection device on its outer side, further improving the reliability of the equipment. A self-locking nut 41 is installed at a designated position on the handle 4 and, through its engagement with the end of the insulating rod body 1, ensures a secure and accurate connection. To enhance the operational stability of this component, a protective cover 42 is added to the outside of the self-locking nut 41, its function being to isolate the influence of the external environment on the internal components. This protective cover 42 is assembled around the outside of the self-locking nut 41, with a sufficiently wide coverage area to prevent dust or foreign objects from entering and causing potential mechanical jamming problems, thereby ensuring the consistency and durability of the overall structural function.

[0033] Specifically, this can be achieved through specific mechanical design. For example, the protective cover 42 can be manufactured from a material with a certain degree of elastic deformation capability, so that it can be precisely fitted onto the outside of the self-locking nut 41. At the same time, the inner wall shape of the protective cover 42 should match the contour of the self-locking nut 41 to form a relatively tight fit, but without affecting normal assembly and disassembly operations due to excessive frictional resistance. This design can be achieved through simple processing while maintaining ease of assembly and functional applicability.

[0034] like Figure 4 As shown, in one embodiment, the stabilizing collar 5 of the insulating operating rod of a power distribution line in this application is located on the outer side of the middle part of the insulating rod body 1, and achieves axial positioning function through frictional cooperation with the insulating rod body 1. To improve stability during operation, an adjustable retaining ring 51 structure is provided, which is embedded in the inner wall of the stabilizing collar 5. The adjustable retaining ring 51 is made of elastic material, and the pressure distribution between it and the insulating rod body 1 is changed by the adjustment mechanism, so that the positioning performance can be dynamically adjusted when subjected to external torque, reducing the occurrence of slippage. In addition, by optimizing the position installation form and force distribution method of the retaining ring, the consistency and reliability of the overall assembly are further improved.

[0035] Specifically, the adjustable retaining ring 51 comprises multiple independent or continuously distributed elastic units, the shape of which is adapted to the inner wall of the stabilizing collar 5 and fixed inside it by a specific connection method. For example, radial pressure is applied to the retaining ring by a knob-type adjustment component to change its deformation to adapt to different operational requirements. Technically, the contact area and pressure distribution between the retaining ring and the insulating rod 1 can be controlled by an embedded spring or a wedge-shaped pad, thereby meeting the stability requirements under external load conditions. The connection method of the components ensures good cooperation between the stabilizing collar 5 and the adjustable retaining ring 51.

[0036] like Figure 5As shown, in one embodiment, the inner wall of the stabilizing collar 5 of the insulating operating rod of a power distribution line in this application undergoes special processing, specifically forming a fine prismatic mesh structure 52 on the inner wall surface of the stabilizing collar 5. This structure is not a traditional smooth or simple frosted finish, but rather, through precise processing, regularly distributed fine prismatic textures are created on the inner wall to enhance the frictional characteristics with the outer side of the insulating rod body 1. The above design is mainly used to provide additional radial damping effect to improve slippage suppression capability and is suitable for applications requiring stronger fixation under high load conditions. Since the stabilizing collar 5 is located on the outer side of the middle of the insulating rod body 1, and the axial positioning between the two is mainly achieved by friction, the design of the fine prismatic mesh 52 directly determines its mating performance.

[0037] For example, a fine prismatic mesh 52 of a specific shape and density can be formed on the inner wall of the stabilizing collar 5 using a precision CNC machine tool or chemical etching process. This process requires strict control of the machining accuracy of the inner wall to ensure the high consistency of the prismatic mesh and its uniform distribution in the circumferential direction, while also avoiding any negative impact on the strength of the collar material itself, thereby ensuring the stability and long-term reliability of the overall structure.

[0038] like Figure 4 As shown, in one embodiment, the structural design of the insulating operating rod of a power distribution line in this application further improves the overall performance by adding a ball bearing 6. The ball bearing 6 is located between the outer surface of the insulating rod body 1 and the stabilizing collar 5. As a mechanical transmission component, its function is to provide radial support and make the force distribution more uniform. The ball bearing 6 consists of an inner ring, an outer ring, and a plurality of evenly distributed balls, which are arranged in a track between the inner and outer rings. During installation, the inner ring of the ball bearing 6 is fixedly fitted to the outside of the insulating rod body 1, while the outer ring is in close contact with the stabilizing collar 5, creating a rolling friction mechanism between them to reduce the sliding friction generated during movement and ensure stability under stress conditions.

[0039] For example, assembly can be completed by first machining a ball bearing 6 with matching dimensions. Specifically, the inner ring of the ball bearing 6 is first tightly embedded into the surface of the precision-ground insulating rod 1, then the outer ring of the ball bearing 6 is assembled with the stabilizing collar 5, and finally the two are checked to ensure that they are on the same axis and fit tightly, thereby ensuring the stability and reliability of the entire device in operation.

[0040] In actual operation, when using this device, the operator first grips the operating lever with the handle 4 and detachably connects the connector 3 to the required operating tool. Next, the length of the insulating rod 1 is adjusted according to site requirements. The three-stage elastic locking assembly 211 within the telescopic locking mechanism 2 ensures a secure engagement between all parts, while its high-strength alloy material effectively bears the force of external loads. Throughout the operation, the stabilizing collar 5 provides axial positioning through friction with the insulating rod 1, preventing overall swaying due to external forces and ensuring the stability of the operation. Finally, all components work together to ensure the smooth completion of power line maintenance operations.

[0041] The specific embodiments described above further illustrate the purpose, technical solutions, and beneficial effects of the embodiments of this disclosure. It should be understood that the above descriptions are merely specific embodiments of the embodiments of this disclosure and are not intended to limit the scope of protection of the embodiments of this disclosure.
