Protective safety net

Abstract

The invention discloses a protective safety net. The protective safety net comprises a vertical rod group or a transverse rod group, and the vertical rod group or horizontal rod group consist of at least two vertical or horizontal rods. The vertical or horizontal rods include a vertical rod a or a transverse rod a, a vertical rod b or a transverse rod b, and connecting rods or connecting sleeves,and the vertical rod a or the transverse rod a, and the vertical rod b or the transverse rod b are separately provided with screw connection ends. The screw-into rotation direction of a threaded opening of the vertical rod a or the transverse rod a is the same as that of the vertical rod b or the transverse rod b, and the two ends of the connecting rods or the connecting sleeves are separately provided with threads suitable for the threaded openings of the vertical rod a or the transverse rod a and the vertical rod b or the transverse rod b. The vertical rod or the transverse rod is formed bythe vertical rod a or the transverse rod a and the vertical rod b or the transverse rod b through the connecting rods or the connecting sleeves, and the two ends of the vertical rod or the transverserod can be retracted or extended at the same time by the screwed connecting rods and the connecting sleeves.

Description

technical field [0001] The invention relates to a protective device, in particular to a protective safety net. Background technique [0002] Windows and corridors of houses are generally equipped with protective nets for safety protection. At present, the use of protective nets is a temporary production and processing method that is welded and fixed into a whole according to the specific dimensions of windows, corridors, etc., and then fixed at safety protection openings such as windows and corridors. Because the protective net is first made into a whole and then installed in safety protection openings such as windows and corridors, the overall protective net has a large weight and takes up a large area of ​​space, which is inconvenient for transportation. Secondly, due to the heavy weight of the protective net itself and the large space occupied, the installation is labor-intensive and the installation efficiency is low, resulting in high cost and low economic benefit.

AI Technical Summary

Problems solved by technology

Since the protective net is made into a whole first and then installed in windows, corridors and other safety protection openings, the overall protective net itself is heavy, takes up a large space, and is inconvenient to transport

Secondly, due to the heavy weight of the protective net itself and the large space occupied, the installation is labor-intensive and the installation efficiency is low, resulting in high cost and low economic benefit. operation, which endangers the personal safety of the installer and is inconvenient

Thirdly, because only temporary processing methods can be used, the size must be measured in advance or booked according to the drawings, which cannot realize mass production and pre-storage in advance, and cannot be flexibly adjusted according to the actual situation. The production, processing and construction period is long, the efficiency is low, and the quality is poor.
