Description

Anti-falling device for lifting window Technical Field The utility model relates to the technical field of door and window safety, in particular to a falling-preventing device for a lifting window. Background With the development of the building industry, the lifting window is more and more widely applied to various buildings. However, the existing lifting window has a certain potential safety hazard in the use process, when the driving mechanism of the lifting window fails or the connecting part is damaged, the moving window can suddenly fall, not only can property loss be caused, but also serious injury can be caused to pedestrians or objects below. Some anti-falling devices in the current market are complex in structure, high in cost and difficult to meet actual use requirements, and reliability is to be improved. Therefore, there is a need to design a safety and reliability lifting window anti-falling device with simple structure and low cost. Disclosure of utility model (One) solving the technical problems Aiming at the defects of the prior art, the utility model aims to provide a falling prevention device for a lifting window, which solves the problems of easy falling, complex structure of the falling prevention device and the like in the use process of the existing lifting window and improves the use safety and reliability of the lifting window. (II) technical scheme The lifting window anti-falling device comprises a moving window and an outer frame, wherein a bearing rod is arranged on the side edge, close to the outer frame, of the moving window in a sliding mode and in the outer frame, a bearing rod running groove is formed in the inner side of the corresponding outer frame, the bearing rod is connected in the bearing rod running groove in a sliding mode along with lifting of the moving window, infrared sensors are arranged on two sides of the bearing rod running groove, a plurality of bolt motors are linearly arranged in the vertical direction of the bearing rod running groove, the lifting window anti-falling device further comprises a controller, the infrared sensors and the plurality of bolt motors are electrically connected with the controller, when the infrared sensors detect that the descending speed of the moving window exceeds a threshold value, the bolt motors are triggered, and transverse pins of the bolt motors pop up to stop the bearing rod to continuously fall. Preferably, the infrared sensor is a grating light curtain sensor and comprises an infrared ray generating end and an infrared ray receiving end, wherein the infrared ray generating end and the infrared ray receiving end are respectively vertically arranged at two sides of the bearing rod running groove, and infrared emission points are correspondingly aligned with infrared receiving points one by one. Preferably, the frame is provided with a guide rail, a roller is arranged on one side of the corresponding movable window, which is close to the frame, and is connected with the side edge of the movable window through a roller connecting plate, and the roller is in rolling connection with the guide rail. Preferably, the guide rail comprises a turning guide rail, and the upper end of the turning guide rail is a inclined rail. Preferably, the bearing rod running groove is a turning running groove, the upper end of the bearing rod running groove is a turning inclined running groove, and the track of the heavy rod running groove is consistent with the track. Preferably, a lifting point is arranged on the side edge of the moving window and used for being connected with a driving mechanism of the lifting window to drive the moving window to lift. (III) beneficial effects The utility model provides a falling-preventing device for a lifting window.
