[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.

[0024] like Figures 1 to 3As shown, an anti-pull fixing structure described in this embodiment is used to fix the wire harness 20 inserted into the hollow lamp pole 10, and the anti-pull fixing structure includes a fixed wire seat 1, a clamping ring 2 and a limiting clamping sleeve 3. The fixed wire seat 1 has a first threading hole 11, and the hole wall of the first threading hole 11 is symmetrically provided with a through hole 12 that penetrates the fixed wire seat 1 in the radial direction, and the top of the through hole 12 extends downward with a buckle 13;

[0025] The clamping ring 2 is arranged at the lower end of the fixed wire seat 1 , the limiting clamping sleeve 3 has a second threading hole 31 , and the limiting clamping sleeve 3 is embedded in the first threading hole 11 and abuts against the inner side wall of the buckle 13 .

[0026] Specifically, when assembling the anti-pull fixing structure described in this embodiment, the fixed wire seat 1 and the limiting clamping sleeve 3 are respectively inserted into the wire harness 20 through the first threading hole 11 and the second threading hole 31, and the buckle 13 is clamped on the outer wall of the wire harness 20. Then, the fixed wire seat 1 is embedded in the third threading hole. At this time, the fixed wire seat 1 is clamped with the lamp pole 10 through the buckle 13, and the clamping ring 2 is inserted into the lamp pole 10 through the third threading hole. Then, the limiting clamping sleeve 3 is embedded in the first threading hole 11. At this time, the outer wall of the limiting clamping sleeve 3 is in contact with the inner wall of the buckle 13, thereby preventing the buckle 13 from swinging in the axial direction of the first threading hole 11, so that the fixed wire seat 1 is firmly clamped on the third threading hole of the lamp pole 10;

[0027] When disassembly is required, the limiting sleeve 3 is taken out from the first threading hole 11. At this time, the limiting sleeve 3 releases the obstruction to the buckle 13, so that the buckle 13 can swing toward the axial direction of the first threading hole 11, so that the buckle 13 can be released from the buckle 13 of the lamp pole 10. In this way, the fixed wire seat 1 can be taken out from the third threading hole, completing the disassembly process.

[0028] In this embodiment, a first threading hole 11 and a buckle 13 are provided on the fixed wire seat 1, and a limiting sleeve 3 is embedded in the first threading hole 11, so that the fixed wire seat 1 is clamped on the lamp pole 10 by the buckle 13 after installation, and the limiting sleeve 3 blocks the buckle 13 at the same time, so that the fixed wire seat 1 is firmly clamped on the lamp pole 10, effectively preventing the fixed wire seat 1 from loosening due to pulling, and the structure is more secure and reliable to use.

In this embodiment, by providing the first clamping platform 16, the fixed wire seat 1 is stably fixed on the third threading hole under the cooperation of the first clamping platform 16 and the buckle 13.

[0034] like Figures 1 to 3 As shown, in the present embodiment, a wire-fixing structure for preventing pulling is provided. In some embodiments, the bottom surface of the first clamping platform 16 is adapted to the outer surface of the lamp pole 10. For example, if the lamp pole 10 is in the shape of a round tube, the bottom surface of the first clamping platform 16 is in the shape of a curved surface. This arrangement allows the wire fixing seat 1 to be more closely attached to the lamp pole 10, and the structure is more stable.

In this embodiment, by providing the card slot 17 and the second card platform 34, the position-limiting card sleeve 3 is firmly fixed in the first threading hole 11, and the structure is more reliable.

[0036] like Figure 2 As shown, in the present embodiment, the anti-pull wire fixing structure is described. In some embodiments, the clamping ring 2 is an E-type clamping ring. In the present embodiment, the E-type clamping ring 2 is used to form a clamping force on the wire harness 20, so that the E-type clamping ring is used to fix the wire seat 1 to effectively prevent the wire from being pulled.
