Detailed Description
A light non-welding variable spring hanger comprises a U-shaped hanger rod 3, wherein an upper pressure plate 2A and a lower pressure plate 2B are arranged on the U-shaped hanger rod 3 in a penetrating mode;
be provided with spring 1 between upper plate 2A and the lower pressure plate 2B, seted up the connecting hole on upper plate 2A and the lower pressure plate 2B, be provided with screw rod 4 and pass the connecting hole to through with screw rod 4 complex nut 5 realizes upper plate 2A and lower pressure plate 2B's location.
Further, the mounting holes 21 of the upper press plate 2A and the lower press plate 2B for connecting with the U-shaped hanger bar 3 form the following structural forms: the inner wall of the mounting hole 21 is provided with an elastic sheet 6, and the upper and lower flanges of the elastic sheet 6 respectively abut against the upper and lower surfaces of the upper pressing plate 2A and the lower pressing plate 2B.
Further, the screw rod 4 is formed in a structure form that the two ends of the screw rod 4 are provided with thread parts 41 matched with the nuts 5, and the middle of the screw rod 4 is in a structure form of a polished rod 42.
Further, the polished rod 42 is provided with a strip-shaped groove, the supporting rod 7 is accommodated in the strip-shaped groove, the end of the supporting rod 7 is provided with a hook 71, and the upper pressing plate 2A and the lower pressing plate 2B are provided with a hanging hole corresponding to the hook 71 facing to the side of the supporting rod 7 to which the upper pressing plate and the lower pressing plate belong.
Further, the support rod 7 is rotatably connected in the elongated groove, and the middle part of the support rod 7 is provided with an adjusting spring 72.
