Antitheft welding-free steel-tube fence

Abstract

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.

Description

technical field [0001] The invention relates to the field of steel pipe fences, in particular to an anti-theft and welding-free steel pipe fence. Background technique [0002] Steel pipe fences are mainly used for perimeter security physical protection, and are widely used in factories, airports, railways, highways, schools, thermal power, water conservancy and docks, and are also widely used in the field of villa construction. Steel pipe fences have a firm structure and good aesthetics. [0003] The steel pipe fence is mainly assembled by welding or bolts of various steel pipes. The construction of the steel pipe fence assembled by bolts is fast, but it is easy to be disassembled, stolen or damaged, while the steel pipe fence with welded steel pipes has a firm structure and is not easy to be damaged, but the construction efficiency is low. The welding quality is difficult to guarantee, and the paint needs to be touched up after welding, and the cost of materials and labor i...
