Stretchable and foldable adjacent-edge protective railing

Abstract

The invention relates to a stretchable and foldable adjacent-edge protective railing, including multiple combination units, and each combination unit comprises two transverse pipes; two ends of each transverse pipe are inserted into a first transverse rod, the two transverse pipes are vertically arranged, a vertical first threaded rod is arranged between each two transverse rods, the upper end andthe lower end of each first threaded rod are sleeved by inner threaded pipes in a matched mode, the upper end of each upper inner threaded pipe is fixedly connected with the bottom of one upper transverse pipe, and the lower end of each lower inner threaded pipe is fixedly connected with the top of one lower transverse pipe. When not in use, the stretchable and foldable adjacent-edge protective railing can be folded after being contracted, is convenient to store and fetch. The stretchable and foldable adjacent-edge protective railing can be quickly installed and used after being taken out andopened, does not need to consume a large amount of time and manpower for temporary assembly during use, can meet the requirements of building adjacent edge protection in different length spaces, andcan change the angle between adjacent combination units according to actual needs, so that the extension direction of the combination unit is changed.

Description

technical field [0001] The invention belongs to the technical field of guardrails, in particular to a stretchable and foldable edge guardrail. Background technique [0002] Most of the guardrails used in building edge protection are iron fence structures, and there are also wire mesh portable fences that are connected to fixed columns by wire mesh. The fence of the iron fence structure is too heavy, which is not conducive to the handling and transportation of the fence, and the space occupation rate after disassembly is large, and the secondary assembly is more complicated. The wire mesh portable steel fence wire mesh is easy to be damaged and entangled, and has a limited service life. It is not convenient for quick installation, and it is difficult to shrink and fold for storage. Contents of the invention [0003] The invention provides a stretchable and foldable edge protection railing to solve the defects in the prior art. [0004] The present invention is achieved th...
