Description

Technical Field

[0001] The utility model relates to the technical field of lamp installation, in particular to an installation structure for installing a wire trough lamp under an I-beam. Background Art

[0002] In factory buildings, I-beams are commonly used as structural beams. Therefore, in traditional practices, the rooting points of pipeline supports all adopt the hoop rooting method, and the forming effect is greatly affected by the installation accuracy of support fittings; the installation suspenders of wire trough lamps commonly use lead screws, and the lead screw suspenders are prone to deformation after installation. Once deformed, they cannot be straightened again later, and the requirements for finished product protection are high. Moreover, the forming effect is relatively average, and it is impossible to ensure straightness in multiple directions in a straight line; for the wire trough used for wire trough lamps, in the traditional splicing process installation, connecting pieces and bolts are used at the joints, which is troublesome to splice. At the same time, due to the small size of the wire trough, even a slight deviation cannot guarantee the straightness of the wire trough. Content of the Utility Model
