DETAILED DESCRIPTION

[0020] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] In this embodiment, Figure 1 The insulating carbon fiber telescopic rod shown in the figure comprises a lower rod body 1 and an upper rod body 2 which is telescopically arranged in the lower rod body 1. The rod head of the lower rod body 1 is rotatably connected to the joint part 3. The outer ring of the rod head of the upper rod body 2 is provided with an external thread, and the inner ring of the joint part 3 is provided with an internal thread matching the external thread, so that the two are tightly connected. The joint part 3 is provided with a rotating locking mechanism 4 for adjusting and fixing the position of the upper rod body 2.

[0022] like Figure 2 and Figure 3As shown, the rotation locking mechanism 4 includes a rotating rod 6 extending into the locking teeth 5 in the lower rod body 1 and a locking assembly installed on the joint 3 for locking the rotating rod 6. The inner wall of the upper rod body 2 is provided with a locking groove 8 for evenly arranging the upper and lower parts and a through groove 9 for the rotating rod 6 to pass through in the vertical direction. The locking teeth 5 are engaged with the locking groove 8 when rotating. The outer ring surface of the upper rod body 2 is smooth and slides against the inner surface of the lower rod body 1.

[0023] like Figure 4 The locking assembly shown includes a fixed end 710 and a movable end 720, the fixed end 710 and the movable end 720 are hingedly connected. Figure 1 As shown, the hinge axis is arranged along the tangent direction of the circumferential side wall of the joint part 3. The fixed end 710 is connected to the joint part 3, and the rotating rod 6 is rotatably arranged in the fixed end 710. The end of the rotating rod 6 forms a positioning groove 601, and a positioning protrusion 721 is fixedly arranged on the movable end 720. The positioning protrusion 721 corresponds to the position of the positioning groove 601 and the shape matches. The movable end 720 is provided with a handle 722 for convenient hand holding and easier fixation.

[0024] like Figure 5 In the illustrated embodiment, the slot 8 penetrates through the side wall of the upper rod body 2 .

[0025] In summary, the locking assembly 7 fixes the rotating rod 6 by matching the shapes and positions of the positioning protrusion 721 and the positioning groove 601. When the rotating rod 6 rotates, the latching teeth 5 rotate and mesh with the latching groove 8, thereby adjusting the position of the upper rod body 2 in the joint 3. The shapes of the positioning protrusion 721 and the positioning groove 601 match, so that the rotating rod 6 is fixed at the position of the positioning protrusion 721 and will not move easily. In this process, the meshing of the latching teeth 5 and the latching groove 8 also provides another reliable fixing mechanism to ensure that the rotating rod 6 will not loosen in the adjusted position. At the same time, the locking assembly 7 achieves stable fixation of the rotating rod 6 by cooperating with the positioning protrusion 721 and the positioning groove 601.

[0026] The insulating carbon fiber telescopic rod solution in this embodiment has the following advantages:

[0027] Made of carbon fiber material, the telescopic rod has high strength and rigidity while maintaining lightness, which is suitable for application scenarios that require high strength and lightness. The upper rod body 2 is telescopically arranged in the lower rod body 1, which is convenient for adjusting the length to meet the needs of different usage scenarios. By rotating the locking mechanism 4, the precise position adjustment and fixation of the upper rod body 2 can be achieved, making the entire telescopic rod structure more compact. The engagement of the latch 5 with the slot 8, and the matching of the positioning protrusion 721 with the positioning slot 601, provide a double fixing mechanism to ensure stability and safety during use. In summary, the insulating carbon fiber telescopic rod can be used in various occasions such as maintenance of power equipment, sports equipment, rescue tools, etc., and has broad market application prospects.
