Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of doors and windows, in particular to a falling-proof door and window. Background Art
[0002] Doors and windows are crucial components of a building's envelope. Depending on their location, doors and windows are classified as either enclosure components or partitions, each with its own design requirements, including insulation, heat insulation, sound insulation, waterproofing, and fire protection. In cold regions, heat loss through gaps in doors and windows accounts for approximately 25% of total heating energy consumption.
[0003] Because winds at high altitudes are much stronger than those at ground level, existing window frame and sash connection components on the market cannot withstand the high wind pressure when open, preventing damage or even detachment. Furthermore, the safety and stability of outward-opening windows are even more difficult to guarantee in harsh environments such as storms, typhoons, and even hurricanes. Falling windows pose a significant safety hazard to people and other objects around the building.
[0004] Therefore, in view of this current situation, it is urgent to design and produce a kind of anti-falling door and window to meet the needs of actual use. Utility Model Content
[0005] The purpose of the utility model is to provide a falling-proof door and window to solve the problems raised in the background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a kind of anti-falling door and window, comprising a door frame with a sliding groove, the side of the door frame is slidably connected to a sliding block, the upper side of the sliding block is fixedly connected to a first limiting rod, the side of the first limiting rod is rotatably connected to a support rod for anti-falling doors and windows, the side of the door frame is rotatably connected to a window body, the side of the window body is fixedly connected to a first fixing plate, the upper side of the first fixing plate is fixedly connected to a second limiting rod, and the side of the door frame is fixedly connected to the second fixing plate.
[0007] Preferably, a limiting groove is provided on the upper side of the second fixing plate, and a side edge of the limiting groove is slidably connected to a support shaft for preventing doors and windows from falling.
[0008] Preferably, one end of the support shaft away from the second fixing plate is fixedly connected to a third fixing plate fixed to the window body, and the support rod is rotatably connected to the second limiting rod.
[0009] Preferably, a fixing rod is fixedly connected to the interior of the door frame, and a side of the fixing rod is fixedly connected to a limiting piece.
[0010] Preferably, a first winding spring is fixedly connected to a side of the fixing rod, and an end of the first winding spring away from the fixing rod is fixedly connected to a first supporting belt.
[0011] Preferably, the first supporting belt is fixed to the window body, and the side of the fixing rod is fixedly connected to a second winding spring for preventing doors and windows from falling.
[0012] Preferably, a side edge of the second winding spring is fixedly connected to a second supporting belt fixed to the window body.
[0013] Compared with the prior art, the technical effects and advantages of this utility model are:
[0014] The anti-falling door and window drives the angle of the support rod to change by opening the window body, thereby driving the sliding block to move. When the hinges between the window body and the door frame are damaged and the window body is about to fall, the support rod and the window body provide support to prevent the window body from falling. At the same time, when the window body is opened, the second fixing plate and the support shaft can provide support for the window body, reducing the pressure between the hinges of the window body and the door frame.
[0015] When the hinges between the window body and the door frame are damaged, the first winding spring provides support for the first supporting belt, and the second winding spring provides support for the second supporting belt, thereby preventing the window body from falling.
