Technical Field
[0001] This utility model relates to the field of elevator guide rail technology, and in particular to a connecting component for a hollow elevator guide rail. Background Technology
[0002] In the elevator manufacturing industry, hollow elevator guide rails are widely used due to their advantages such as lightweight and high material utilization. However, existing hollow elevator guide rail connectors have significant technical problems in practical use. On the one hand, traditional connectors mostly use a single bolt to connect the hollow guide rail. Due to the limited strength of the hollow structure itself, the connection is prone to loosening, deformation, or even breakage under repeated loads during elevator operation, resulting in insufficient stability of the guide rail connection and affecting the safety and reliability of elevator operation. On the other hand, the structural design of existing connectors often lacks an efficient positioning and guiding mechanism, requiring repeated adjustments and alignment during installation, which not only increases the installation difficulty but also reduces construction efficiency. At the same time, some connectors do not have effective reinforcement structures, making it impossible to specifically reinforce the connection parts of the hollow guide rail, which is difficult to meet the needs of elevators operating under high loads for extended periods. Therefore, it is necessary to design a connector for hollow elevator guide rails to solve the above problems. Utility Model Content

Two second screw holes 35 are provided at both the front and rear upper ends of the hollow guide plate 31. Two slots 34 are provided at the lower left end of the hollow guide plate 31, and the two slots 34 are symmetrically distributed front and back. The right end of the connecting plate 21 fits against the left end of the hollow guide plate 31, and the two insertion blocks 25 on the right side are inserted into the slots 34 one by one. Inside, the first screw hole 26 and the second screw hole 35 are coaxially aligned. The plug-in blocks 25 are all I-shaped structures.
