Description

Technical Field

[0001] The invention relates to the technical field of rail transportation, in particular to an externally mounted channel connector. Background Art

[0002] With the development of the rail transit industry, troughs have been widely used. Usually, a series of problems are found in the application process of troughs, such as load bearing problems, service life problems, maintenance and replacement problems, etc. For maintenance and replacement, many people use embedded stainless steel sleeves, but most of the general sleeves are made of stainless steel, and there are many problems: one is the problem of thread damage. Due to the nature of the stainless steel material itself, the thread strength is not high and it is very easy to be damaged. Once damaged, it cannot be repaired because the sleeve is embedded in the concrete; the second is the anti-loosening problem. Without an effective anti-loosening mechanism, it cannot be guaranteed that it will not loosen during operation. Therefore, external trough connectors are often required when laying the trough.
