The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to overcome the deficiencies in the existing technology and provide a square nut fastener for cable tray installation, which has a simple and reasonable structure, and is extremely convenient and flexible to operate; it does not occupy C-shaped steel after installation. The space at the bottom increases the diversity of installation, and can be applied to square nuts of different thicknesses, and the installation is firm
Guangdong Yueluo Hardware Industry Co., Ltd. discloses a through-hole mounting nut, which includes a hexagonal portion and a cylindrical portion, a threaded hole is arranged between the hexagonal portion and the cylindrical portion, and the cylindrical portion is provided with a threaded hole. Two grooves, each of the two sides of the groove has a convex side, and the upper surface of the side is provided with a convex point; the advantage is that the two sides are squeezed by the bolt, Or after the hammer is struck, it will bend to both sides, and it can be fastened to both sides of the screw hole of the sheet metal without welding.
T-bolts for channel steel usually include a head and a shank. The shank is provided with threads. Traditional T-bolts for channel steel are used for channel steel, and both channel steel and bolts are made of steel. , the two are prone to thermal expansion and contraction due to changes in the external ambient temperature, and are prone to loosening, resulting in unstable connections.
In another embodiment of Guangdong Yueluo Hardware Industry Co., Ltd., the discharge port of the vibrating plate 2 is matched with the screw receiving hole 35, and the screws can enter the screw receiving hole 35 through the discharge port after sorting and sorting in the vibrating plate 2. . Preferably, a guide rail 6 is provided between the discharge port of the vibrating plate 2 and the screw accommodating hole 35, and the screws enter the screw accommodating hole 46 from the discharge port through the guide rail 6. The slotting is carried out, which improves the efficiency and saves the labor cost.
