Abstract

The invention discloses an elevator door opening protective fence convenient to assemble and disassemble. The protective fence comprises transverse pipes; the two ends of each transverse pipe are provided with fixing assembles which are detachably connected to a side wall of an elevator door opening correspondingly; each fixing assembly comprises a fixing rod and an adjusting rod which are transversely arranged, are each in an L shape and are each composed of a side rod and a bent part; the side rod of each fixing rod and the side rod of the corresponding adjusting rod are connected to form a U shape; and the side rod of each adjusting rod can slide in the length direction of the side rod of the corresponding fixing rod and be positioned, the bent part of the adjusting rod and the bent part of the fixing rod both face towards the side wall of the elevator door opening, and a clamping spring is fixedly installed between the bent part of the adjusting rod and the top end of the side rod of the fixing rod. When the fixing assemblies are used, the adjusting rods or the fixing rods are pulled towards the interior or the exterior of an elevator shaft, the distance between the bent part of each adjusting rod and the bent part of the corresponding fixing rod is changed, accordingly, the width of each fixing assembly is adjustable, and the fixing assemblies can be suitable for fixing walls of different specifications.

Description

technical field [0001] The invention relates to a safety protection device in building construction, in particular to an elevator door opening protection fence which is easy to install and dismantle. Background technique [0002] With the improvement of living standards, most buildings will be equipped with elevators to facilitate people's going up and down. Before the building construction is completed, it is necessary to set up protective barriers at the elevator door openings on each floor to prevent accidents. At present, the setting method of many guardrails is as follows: a plurality of horizontal steel pipes arranged up and down are arranged at the elevator door opening, and fasteners are used to fix the two ends of the horizontal steel pipes on the side wall of the elevator door opening. Although this kind of guardrail has a simple structure and is easy to install, the length of the horizontal steel pipe cannot be adjusted in real time. At the same time, it is very ...
