According to news from the financial industry on November 14, 2024, information from the State Intellectual Property Office shows that Hunan Hongmen New Material Technology Co., Ltd. has obtained a patent called \”Guide Rail Connection Structure and Lifting Door\”. Authorization announcement number CN 221990144 U, application date is March 2024.
The patent abstract shows that the embodiment of the present application relates to the technical field of door equipment, and in particular to a guide rail connection structure and a lifting door. The guide rail connection structure includes a support member, an upper guide rail, a lower guide rail and a guide rail positioning component. The upper guide rail and the lower guide rail are spliced to each other. The guide rail positioning component is installed on the support member. The guide rail positioning component is provided with a positioning slot that matches the outer contour of the upper guide rail and the outer contour of the lower guide rail. Among them, the upper guide rail is fixedly connected to the support member, and the lower guide rail is fixedly connected to the guide rail positioning component. Both the upper guide rail and the lower guide rail are partially contained in the positioning slot, and are positioned and aligned with each other through the side walls and bottom surface of the positioning slot. In this application, through the above settings, the upper guide rail and the lower guide rail are positioned, aligned, spliced, and relatively fixed. Compared with the positioning method that uses pin holes and cylindrical pins to match each other, mutual misalignment or separation between the upper guide rail and the lower guide rail is avoided.
