A push-pull plastic-steel door and window reinforcement device

Abstract

The invention discloses a push-pull plastic steel door / window reinforcement device comprising a door / window body. A track groove is formed in the bottom side of the door / window body; a door / window track is installed in the track groove in a sliding manner; and the bottom side of the door / window track extends out of the track groove and a pedestal is fixedly installed. A placing cavity is opened onthe door / window track; a same rotating shaft is fixedly installed on the inner walls of the two sides of the placing cavity; a moving rod sleeves the rotating shaft in a rotating manner; and semi-circular wheels are fixedly installed at the top and the bottom of the moving rod. A first rack is installed on the inner wall of the bottom side of the placing cavity movably; and a first push rod through hole and a second push rod through hole are opened on the inner wall of one side of the placing cavity. The push-pull plastic steel door / window reinforcement device has a simple structure. When thedoor / window body shakes, the first push rod is pushed to move and thus the semi-circular wheels on the moving rod rotate; and with continuous pushing of the first push rod, the second rack pushes a second push rod to extrude the door / window body tightly. Therefore, a problem of shaking of the door / window body is solved; and the push-pull plastic steel door / window reinforcement device is used conveniently.

Description

technical field [0001] The invention relates to the technical field of door and window reinforcement, in particular to a push-pull plastic-steel door and window reinforcement device.

[0003] Publication No. CN205778232U discloses a push-pull plastic-steel door and window repair and reinforcement device. The two wings of the U-shaped reinforced slideway are connected with the door and window frame of the push-pull plastic-steel door and window through connectors. The thickness of the U-shaped reinforced slideway is 0.5mm. The present invention directly Reinforced on the outer surface of the original damaged plastic-steel slideway, no need to replace the original door frame and window frame, no damage to the door and window decoration or window sealing and waterproof, simple, practical, convenient, and low maintenance cost, but the door and window body in this patent is exposed to windy weather When the door and window body will be blown by the strong wind, it will hit the door and window track and produce noise. The noise will affect people's rest. At the same time, if the impact time is too long, it will cause damage to the door and window. need
