Antitheft welding-free steel-tube fence
The invention discloses an antitheft welding-free steel-tube fence comprising horizontal steel tubes and vertical steel tubes. The horizontal steel tubes and the vertical steel tubes are connected through elastic fasteners which are arranged in the vertical steel tubes respectively. Each elastic fastener comprises a fixing plate, a first protrusion block and a second protrusion block, wherein the first protrusion block and the second protrusion block are arranged at two ends of the front face of the fixing plate. The vertical steel tubes are provided with first open holes and second open holes corresponding to the first protrusion blocks and the second protrusion blocks. The first protrusion blocks and the second protrusion blocks cling to the inner walls of the horizontal steel tubes. Two elastic arc-shaped plates extending outwardly are arranged on the reverse side of each fixing plate symmetrically. The antitheft welding-free steel-tube fence has the advantages that the antitheft welding-free steel-tube fence is mounted rapidly and conveniently and has high durability; the antitheft welding-free steel-tube fence is locked automatically after being mounted, thereby being difficult to damage and high in safety protection and theft prevention performance; welding and bolt connection are not needed, and accordingly, material and labor costs are reduced.
