Detailed description of the invention
In conventional art, mostly all use solid guide rail to carry out outer connection, complicated inconvenience is installed, at present, market has occurred the hollow guide rail connected in adopting, but hollow T-shaped guide rail is poor in the junction structural strength of rail head and the flange of rail, easily damages, there is potential safety hazard, and the junction of two guide rails of docking is difficult to alignment, easily offsets after connection, guide rail flatness after serial connection is poor, and rail elevator running noises is larger.In addition, the two ends of guide rail arrange connecting bore, are connected by two guide rails by connecting panel, but conventional guide rails end only arranges two connecting bores, connect compactness poor.
The utility model is for deficiency of the prior art, propose a kind of T-shaped hollow cage guide, by the lower end of rail head being tightened up to the inside and arranging convex tendon, to increase the structural strength of guide rail, skew when avoiding guide rail to connect, ensure the flatness of guide rail, increase the compactness that guide rail connects simultaneously, improve the structural strength of guide rail.
