The example in the middle adopts a T shape, and the guide rail groove 211 of the outer guide rail is slidably sleeved in the guide rail groove 221 of the inner guide rail.

Through the inner guide rail 22, the outer guide rail 21 and the inner and outer rail connectors, the length of the guide rail can be adjusted arbitrarily within a certain range, so it can meet the needs of installing photovoltaic modules on various special-shaped sloping roofs, and overcome the need for accurate measurement of size data in the prior art , and the increase in workload and the decrease in efficiency brought about by precision cutting guide rails. And through the alternate sleeve of the inner guide rail 22 and the outer guide rail 21, the guide rail can be extended infinitely, because it brings great convenience to the construction, while the traditional guide rail extension requires on-site cutting, which is time-consuming and laborious. The guide rail grooves 221 and 211 of the inner guide rail 22 and the outer guide rail 21 are arranged on an axis, which can easily pass through the connecting plate 12 and the connecting bolts respectively arranged in the guide rail grooves 221/211 (generally adopt T-shaped bolt assemblies, use guide rail The groove body of the groove is restricted to prevent the bolts from rotating) to connect the inner guide rail to the outside or the outer guide rail to retract within a certain range, so as to adjust the length of the entire guide rail conveniently. The suitable outer guide rail can be selected on site ( For example, it is slightly shorter than the required size), and after selecting an inner guide rail of an appropriate size, the required precise size guide rail can be assembled. When the guide rail corresponding to each position is prefabricated in the factory according to the measured size, since the length of the guide rail can be adjusted, the requirement for the accuracy of the cutting size is greatly reduced.
