Lifting type anti-theft shutter

Abstract

An elevation type safety shutter belongs to the field of building doors and windows and consists of a window frame with a hollow cavity, a movable fence and a shutter leaf (77). A self-locked elevation type device on the fence, a self-locked manual and a power-driven leaf revolving device, a firm and beautiful fence rod (76) and hinge, and a lock-up device are designed through separating the fence from the shutter leaf (77). The safety shutter has the functions of theft proof, rain proof, ventilation, privacy protection, noise reduction, sun shading and energy saving, indoor light adjusting and surviving in a fire accident and the like; besides, after furling, the fence leaf occupies little space of the window upper part, thus leading the elevation type safety shutter to become a construction piece necessary for each family and a powerful instrument for improving city view.

[0002] At present, the windows of urban residences are mainly sliding windows. When the sliding windows are opened, they do not occupy space and can control the air intake. The measures taken are to install anti-theft fences, anti-theft nets and alarms on the outer walls or inner walls of windows. Open the window to escape, and the cage-like fence has greatly affected the image of the city; in order to overcome the defects of the fixed anti-theft fence, people have designed various forms of movable anti-theft fences and anti-theft nets, but these have not changed the image of the city much. function; the alarm seems to have solved these defects of the fixed anti-theft fence and anti-theft net, but practice has proved that its false alarm rate is high, which often makes people a false alarm, and it cannot satisfy people's visible and tangible needs. That kind of psychological security, and its aging degree is relatively high. People need to replace it every few years, which is too expensive.

[0003] Chinese patent ZL200620170171.X discloses a "multi-functional liftable safety anti-theft shutter", which consists of a window frame with a cavity and a shutter leaf. The cavity of the window frame is equipped with a lifting device connected to the shutter leaf and Turning device, the two ends of the window leaf are installed in the chute on both sides of the window frame through the end connector, and the window leaves are connected by opening and closing claws; the lifting device is composed of pulleys, wire ropes, chains, Composed of steering gear, lifting rod and connecting buckle, the wire rope is installed on four pulleys, one end of the wire rope is connected to one end of the chain through the connecting buckle, the other end of the wire rope is connected to the other end of the chain, and the chain is installed on the gear on the pulley. And through the steering gear to change the direction, the two ends of the lifting rod are fixed on the steel wire ropes on both sides, and connected with the lowermost window leaf; the turning mechanism is composed of a rotating shaft, a runner, a support, a pull rope and a blade turning device, and the rotating shaft passes through The support is fixed in the upper side of the window frame, and the rotating shaft is equipped with runners. The pull ropes on the two runners are connected with the two end connectors of each window leaf, and the pull rope on the other runner is connected with the blinds installed on the blinds. The blade flipper on one side is connected to the lock; the lifting rod is equipped with a window lock used in conjunction with the lower side of the window frame; the shortcoming of the patented technology of this invention is that the steel pipe passing through the middle of the blade is fixed at both ends, and is not connected to each other. Without other reinforcements, it is very easy to be damaged when the span is large; the steel pipe passes through the middle of the blade, which increases the thickness of the blade, resulting in insufficient lighting; Lighting Amount and Appearance Image
