An adjustable protective window for building construction

Abstract

The invention discloses an adjustable protection window used for building construction. The adjustable protection window comprises a chassis. The chassis is provided with four adjusting jigs. Each adjusting jig is formed by an inner pipe, an outer pipe, an expansion link, a sleeve, a side board, a moving rod, stretchable legs, a protection frame, and a lever assembly. The outer end of the outer pipe is fixedly connected with the middle part of the side board. The inner end of the inner pipe is fixedly connected with the chassis. The center of the chassis is provided with a cam which can rotate or lock. When the cam rotates, the expansion link is pushed outward. The lever assembly of each adjusting jig is provided with a left group and a right group which are symmetrically arranged on two sides of the outer pipe. Each group of the lever assembly is formed by a first hinge base, a second hinge base, a third hinge base, a fourth hinge base, a first lever, a second lever, a third lever, and a fourth lever. The adjustable protection window used for building construction can be firmly installed in window holes through rotating the cam. The window has an antitheft effect, and installation is convenient, and the window can be repeatedly used.

Description

technical field [0001] The invention relates to a building construction appliance, in particular to an adjustable protective window for 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 w...

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

[0003] On the other hand, in the buildings that have been built, anti-theft windows are generally installed on the windows of the building to prevent theft. The installation of the anti-theft windows is relatively complicated, and screws need to be drilled. Set security windows

For tenants, the house is not their own. Once the rented house does not have anti-theft windows, it is very inconvenient to remove the installed anti-theft windows. Tenants seldom install anti-theft windows. This is a problem. Anti-theft windows are not required, but protective measures must be taken for children inside. Many cases have shown that children aged two or three will climb out and cause safety accidents because there are no protective measures for windows above the tenth floor.
