Levered protective window for use in building construction

Abstract

The invention discloses a levered protective window for use in building construction, comprising an outer frame which is rectangular. The center of the outer frame is provided with a bottom plate; tubes are disposed between the outer frame and the bottom plate; a telescopic bar is disposed in each tube; the outer end of each telescopic bar is a reducing segment; the center of the bottom plate is provided with a cam; when the cam rotates, blades can push out the telescopic bars; two side walls of each tube are provided with through slots; left and right fixing bars extending out of the through slots are fixedly connected to each telescopic bar; a first hinging block and a second hinging block are arranged on two sides of each tube; a first lever is hinged to each first hinging block; a second lever is hinged to each second hinging block; a telescopic foot is arranged outside the other end of each second lever. The levered protective window has the advantages that by rotating the cam, the window can be firmly mounted in a window hole to allow burglary prevention, mounting is facilitated, waste of raw materials is avoided, no nail hole is left, and the window is highly practical.

Description

technical field [0001] The invention relates to a protective window, in particular to a lever-type protective window used in building construction. Background technique [0002] Now in the construction process, usually along with the construction of the house, the installation position of the window is reserved on the house (generally a rectangular window hole, and a window can be installed in the window hole). Especially in rural houses, after the house frame is built, because it has the basic function of sheltering from the rain, many items are usually placed in the house frame, such as building materials, such as cement, which can play a waterproof role in the house frame. In addition, such as paint powder, etc., other building construction tools can also be placed in the house frame, so that a protective structure needs to be set at the position of the window hole to realize the basic anti-theft function; The wooden boards are arranged crosswise to seal the window hol...

AI Technical Summary

Problems solved by technology

Especially in rural houses, after the house frame is built, because it has the basic function of sheltering from the rain, many items are usually placed in the house frame, such as building materials, such as cement, which can play a waterproof role in the house frame. In addition, such as paint powder, etc., other building construction tools can also be placed in the house frame, so that a protective structure needs to be set at the position of the window hole to realize the basic anti-theft function; The wooden boards are arranged crosswise to seal the window holes, so there are three problems: 1. After the demolition, there will be many holes left by nails on the wall, and the cement on the inner wall will fall off during the knocking process, which needs to be repaired later; 2. 1. The wooden boards are useless after being dismantled, causing waste; 3. The process of nailing the wooden boards is more complicated and labor-intensive
