Convenient automatic windproof locator for door leaf and window sash

Abstract

The invention discloses a convenient automatic windproof locator for a door leaf and window sash. The locator comprises a machine body, wherein a cavity representing the door and window space is formed in the machine body, rotating grooves with opposite openings are symmetrically formed in the left side and the right side of the cavity, a rotating shaft is rotationally arranged between the upper end wall and the lower end wall of each rotating groove, sealing plates representing the door sash or the window sash is fixedly arranged on the rotating shafts, and locking cavities are formed in thelower sides of the rotating grooves in a communicating mode. According to the locator, during working, through the coordination connection between ratchet wheels and locking blocks which can be meshedwith the ratchet wheels, the opening angle of the groove sash or the door leaf can be accurately positioned, moreover, automatic clamping is achieved, the reverse rotation of the ratchet wheel, namely closing of the window sash or the door leaf is prevented so that the window sash or the door leaf cannot be shaken in strong wind weather, secondly, when the window sash or the door leaf is in the closed state, the clamping blocks are locked, so that the door leaf or window sash cannot be automatically opened in strong wind weather or damaged due to vibration caused by the strong wind during strong wind, moreover, the opening angle is not affected by the length of a positioner, and then the window sash or the door leaf can be opened with any angle.

Description

technical field [0001] The invention relates to the field of windproof devices, in particular to a convenient automatic windproof positioner for doors and windows. Background technique [0002] The windproof positioner plays an important role in preventing the window or door from shaking in windy weather, and prolongs the service life of the window or door. At present, the windproof positioner is mainly used to fix the openable side of the window or door to the window frame or door frame through a slide bar. This device is affected by the length of the positioner and the size of the window or door space, so the window or door can only be opened at a certain angle, which is extremely inconvenient. Secondly, the current automatic windproof positioner needs to be unlocked and positioned to close the window or door when encountering strong winds. When the door leaf is used, it is often manually unlocked, the degree of automation is low, and the closed window or door leaf does no...

[0002] The windproof positioner plays an important role in preventing the window or door from shaking in windy weather and prolongs the service life of the window or door. The windproof positioner that is commonly used at present is to fix the openable side of the window or door to the window frame or door frame through a slide bar. This device is affected by the length of the locator and the size of the window or door space, so the window or door can only be opened at a certain angle, which is extremely inconvenient. Secondly, the current automatic windproof locator needs to be unlocked and positioned to close the window or door when encountering strong winds. When the door leaf is used, it is often manually unlocked, the degree of automation is low, and the closed window or door leaf does not have a clamping device to improve the closing stability of the window or door leaf. This device of the present invention can solve this problem
