The invention discloses a novel efficient anti-loose single-
pipe earthquake-proof supporting-hanging device comprising a base, a sleeve, a connecting frame, a sliding groove, a first clamping groove,a fixing bolt, a fixed column, an inner thread, a first spring, a sliding limiting plate, a connecting column, a connecting rod, an outer thread, an inner cavity, a second spring, a fixed clamping block, a first clamping block, an upper arc part, a lower arc part, a second clamping block and a second clamping groove. The single-
pipe earthquake-proof supporting-hanging device is reasonable in structure and novel in design, a single
pipe can be supported and hung better, the condition that the upper arc part and the lower arc part are fixed with bolts is omitted, the conditions that the bolts are used for a long time, consequently bolt threads are abraded, and connection stability is influenced are avoided, stable connection between the upper arc part and the lower arc part is achieved, theservice life of the single-pipe supporting-hanging device is prolonged, use is convenient, earthquake-proof performance of the supporting-hanging device is improved, the condition that after installedand used, a placed pipeline is damaged by earthquakes and other factors is avoided, the practical value is high, and the novel efficient anti-loose single-pipe earthquake-proof supporting-hanging device is suitable for use and popularization.
