Description

Technical Field

[0001] This utility model belongs to the field of cable protection pipe technology, and specifically relates to a spliced ​​anti-detachment structure for cable protection pipe. Background Technology

[0002] Cables are essential electrical infrastructure in power engineering construction, used for power transmission. Cable laying is not limited to a single environment, and complex environments are common in power construction. Therefore, in modern power construction, protective conduits are added to the outside of the cable to improve its rainproof performance, protect it from damage and leakage, extend its service life and safety, and select different protective conduits based on the actual needs of different construction sections. In actual use, cable protective conduits are not single, monolithic installations, but rather composed of several groups of individual sections. Adjacent sections of cable protective conduits need to be spliced. Current technology uses bolts and nuts to achieve a secure splicing; however, these threads are prone to corrosion over time, increasing the difficulty of later maintenance and requiring additional tools, further complicating the splicing process.

[0003] In summary, we hope to propose a new structure to solve the aforementioned technical problems. Utility Model Content

[0031] Three sets of buckles 102 are fixedly connected to the right side of the tube body 101 in a circumferentially evenly distributed manner. Three sets of limiting grooves 103 are provided on the left side of the tube body 101 in a circumferentially evenly distributed manner for cooperating with the buckles 102 for limiting. A retaining ring groove 104 is provided on the left end of the outer side of the tube body 101.

The reinforcement connectors 200 include connecting rods 201 and fitting columns 206. Two sets of symmetrically arranged fitting columns 206 are movably arranged on the inner side of the right end of the connecting rods 201.

[0033] The buckle 102 passes through the limiting groove 103 and its end is placed inside the retaining ring groove 104. The outer side of the buckle 102 has an arc-shaped structure and is set with the tube body 101 as equal to the circular structure. After the buckle 102 passes through the limiting groove 103, the end of the buckle 102 is fitted with the retaining ring groove 104, which can realize quick pre-connection and use.
