Description

Technical Field

[0001] This utility model relates to the field of insulator technology, specifically a composite insulator. Background Technology

[0002] A combined insulator, disclosed in Chinese patent document CN218181962U, relates to the field of insulator technology. It includes an end seat, a support column fixedly mounted on the upper end of the end seat, a rubber sleeve on the outer surface of the support column, a long strip fixedly mounted on the outer surface of the support column, a long groove on the inner surface of the rubber sleeve, external threads on the outer surface of the rubber sleeve, and an internally threaded post on the outer surface of the rubber sleeve. An insulating disc is fixedly connected to the outer surface of the internally threaded post. The end seat has an assembly hole. The system comprises an end seat, support column, rubber sleeve, long strip, long groove, threads, internally threaded post, insulating disc, assembly hole, mounting platform, threaded hole a, bolts, and limiting block. When an insulating disc is damaged, the long groove and long strip can be used to install the rubber sleeve on the outside of the support column, creating threads on the surface of the support column. Then, the internally threaded post can be removed from or screwed into the rubber sleeve using the threads. This facilitates the replacement of damaged insulating discs without replacing the entire insulator, reducing maintenance costs.

[0003] However, in the above-mentioned solutions and existing technologies, in actual power transmission environments, due to the various complex external forces acting on the lines, there are still some shortcomings in quickly and accurately installing the insulator components into the predetermined positions during the installation process, which may increase the installation difficulty and time cost. Therefore, optimization and improvement can be carried out.

[0004] Therefore, this utility model proposes a combined insulator to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a combined insulator to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a combined insulator, comprising an insulator body, sheds, a central hole, a snap-fit ​​assembly, a buffer assembly, and a fixing assembly;

[0007] The insulator body is provided with a shed skirt, and a central hole is provided in the middle of the insulator body;

[0008] The snap-fit ​​component is disposed on the center hole, the buffer component is disposed on the snap-fit ​​component, and the fixing component is disposed on the center hole.

[0009] Preferably, the snap-fit ​​rods in the snap-fit ​​assembly are fixedly and evenly disposed on the fixed rod, and the snap-fit ​​rods are provided with snap-fit ​​grooves.

[0010] Preferably, the snap-fit ​​assembly has snap-fit ​​protrusions that are adapted to slide and snap-fit ​​in the snap-fit ​​groove, and the snap-fit ​​protrusions are evenly distributed on the fixing sleeve of the central hole.

[0011] Preferably, one end of the buffer pad in the buffer assembly is fixedly mounted on the fixed sleeve, and the other end of the buffer pad is fixedly mounted inside the snap-fit ​​protrusion. Positioning telescopic rods are evenly arranged on both ends of the snap-fit ​​protrusion.

Detailed Implementation

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1: Please refer to Figures 1-2 A composite insulator includes an insulator body 1, a shed 2, a center hole 3, a snap-fit ​​assembly 4, a buffer assembly 5, and a fixing assembly 6; the shed 2 is provided on the insulator body 1, and the center hole 3 is provided in the middle of the insulator body 1; the snap-fit ​​assembly 4 is provided on the center hole 3, the buffer assembly 5 is provided on the snap-fit ​​assembly 4, and the fixing assembly 6 is provided on the center hole 3.

[0022] The snap-fit ​​rods 401 in the snap-fit ​​assembly 4 are fixedly and evenly arranged on the fixed rods 402, and snap-fit ​​grooves 403 are provided in the snap-fit ​​rods 401.

[0023] In use, the fixing rod 402, carrying the evenly distributed snap-fit ​​rods 401, is first placed around the central hole 3 in the middle of the insulator body 1. During this process, it is necessary to ensure that the relative position of the snap-fit ​​rods 401 and the central hole 3 is accurate, so as to build the basic structure for the subsequent installation of various components. As a key connecting component, the evenly distributed design of the snap-fit ​​rods 401 fixed on the fixing rod 402 can ensure the stability and balance of the subsequent connection, and provide initial guarantee for the installation accuracy of the entire combined insulator.

[0024] Example 2: Based on Example 1, please refer to... Figures 2-3 The snap-fit ​​assembly 4 has snap-fit ​​protrusions 404 that are adapted to slide and snap-fit ​​in the snap-fit ​​groove 403. The snap-fit ​​protrusions 404 are evenly distributed on the fixing sleeve 405 of the center hole 3.

[0025] One end of the buffer pad 501 in the buffer assembly 5 is fixedly mounted on the fixed sleeve 405, and the other end of the buffer pad 501 is fixedly mounted inside the snap-fit ​​protrusion 404. Positioning telescopic rods 502 are evenly arranged on both ends of the snap-fit ​​protrusion 404.

[0026] In use, the snap-fit ​​protrusion 404 on the fixed sleeve 405 is aligned with the snap-fit ​​groove 403 on the snap-fit ​​rod 401 and inserted. Since the snap-fit ​​groove 403 and the snap-fit ​​protrusion 404 are compatible, they will automatically guide and slide to the appropriate position during insertion, completing the initial positioning. At this time, the buffer pad 501 plays a role. It is located between the snap-fit ​​protrusion 404 and the fixed sleeve 405, which can effectively buffer the impact force that may be generated during the installation process and avoid damage to the parts. At the same time, the positioning telescopic rods 502 on both sides of the snap-fit ​​protrusion 404 can be finely adjusted according to the actual installation situation to ensure the accuracy of the installation position.

[0027] Example 3: Based on Example 2, please refer to... Figure 3 one Figure 4 The positioning telescopic rod 502 in the buffer assembly 5 is fixedly connected to the outside of the telescopic spring 503. The end of the positioning telescopic rod 502 is provided with a sliding protrusion 504. The sliding protrusion 504 is adapted to slide and engage with the engagement hole 505. The engagement holes 505 are evenly distributed on both sides of the engagement rod 401.

[0028] The fixing pin 601 in the fixing component 6 fixes the fixing sleeve 405 to the fixing rod 402. The fixing sleeve 405 is provided with a mounting hole 602.

[0029] In use, the positioning telescopic rod 502, under the elastic action of the telescopic spring 503, pushes the sliding protrusion 504 at its end, so that it accurately engages with the evenly arranged engagement holes 505 on both sides of the engagement rod 401. This operation further stabilizes the entire structure and enhances the tightness of the connection between the components. After completing the above steps, the fixing sleeve 405 is firmly fixed to the fixing rod 402 by the fixing pin 601 in the fixing assembly 6, ensuring a stable and reliable connection. Finally, the mounting hole 602 on the fixing sleeve 405 can be used to connect and fix with external equipment to meet the installation requirements in actual use scenarios.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
