Window guardrail with security function

Abstract

The invention discloses a window guardrail with a security function. The window guardrail structurally comprises an upper connecting rod, handrails and a lower connecting rod, the upper connecting rodis fixed to the upper ends of the handrails, and the handrails are connected with the lower connecting rod. Through outer pipes on the handrails, when parthenocissus tricuspidata is wound around theouter surfaces of the outer pipes, the whole parthenocissus tricuspidata generates downward gravity pulling on the outer pipes, thus the outer pipes can rotate along a connecting strip, so that parthenocissus tricuspidata vines wound on the outer surfaces of the outer pipes can be reversely rotated out, and the situation that the roots of parthenocissus tricuspidata penetrate into the space between an outer push block and the inner wall of a bearing ring can be avoided; through springback pieces, outer unfolding plates which lose extrusion of the inner wall of an upper placing plate can be pushed towards the two sides to slide and unfold towards the two sides, so that pulling blocks can be blocked by the parthenocissus tricuspidata to swing upwards, and thus the pulling blocks can pull apart the roots of parthenocissus tricuspidata vines wound on the outer surfaces of the handrails along with the outer unfolding plates in the unfolding process.

Description

technical field [0001] The invention relates to the security field, in particular to a window guardrail with a security function. Background technique [0002] The security window guardrail is mainly used for the safety protection of the window area. It is usually installed on the outside of the window to improve the safety performance of the window, and the security window guardrail is mostly made of stainless steel or painted iron metal pipes. Common equipment in life, based on the above description, the inventor found that the existing window guardrail with security function mainly has the following deficiencies, for example: [0003] If the safety window guardrail is installed on a window that is lower than the ground on the first floor, and vines such as ivy will be planted around the walls of some buildings for landscaping, so that the ivy under the window will easily become entangled in the safety protection when it grows up. As a result, the root of the creeper will...

Problems solved by technology

[0003] If the safety window guardrail is installed on a window that is lower than the ground on the first floor, and vines such as ivy will be planted around the walls of some buildings for landscaping, so that the ivy under the window will easily become entangled in the safety protection when it grows up. As a result, the root of the creeper will scratch the aging paint on the iron metal pipe that has been used for a long time when it extends out, which will cause the iron metal to be prone to accelerated oxidation and rust, thus deteriorating the security performance of the safety window guardrail. decline
