Switch locking device for shutter

Abstract

The invention discloses a switch locking device for a shutter, which comprises a rocker arm (2) and a ratchet-gear wheel (3), a blocking piece (9), a lock tongue (4), a sliding slot (10), a rotary connecting bar (5), and a sash frame groove (6), wherein the rocker arm (2) and the ratchet-gear wheel (3) are fixedly connected with a window shaft, the blocking piece (9) is used for blocking the ratchet-gear wheel (3), the lock tongue (4) is arranged at the inner side of the window frame bar, and the sliding slot (10) correspond to the lock tongue and is used for the sliding of the lock tongue, one end of the rotary connecting bar (5) is rotatably and pivotably supported at the bottom of the window frame, and the other end of the rotary connecting bar (5) is connected with the lock tongue (4), and the sash frame groove (6) is correspondingly arranged at the same side with the sliding slot (10) used for the sliding of the lock tongue of the window frame; the lock tongue ascends or descends by means of the rotation of the rotary connecting bar in the vicinity of a position which is perpendicular to the window frame, therefore, the shutter can be opened, closed and locked at any opening status. The switch locking device can be used as a 120-degree horizontal or vertical rotary switch for a middle shaft axis rotary shutter. Therefore, the opening space is large, the switch locking device has excellent ventilation, permeation, lighting performance, permeability, high sealing performance, sound insulation and anti-theft performance. Furthermore, the outer side of the window sash of the shutter is convenient to clean.

Description

technical field [0001] The present invention relates to the construction field, in particular, the present invention relates to a door and window structure of a building, more specifically, the present invention relates to a multi-leaf window switch locking device, and the multi-leaf window switch locking device is especially used for a new The central axis rotary multi-leaf window, using the multi-leaf window switch locking device of the present invention, can make the multi-leaf window be used as a rotary switch in the horizontal or vertical direction of 120°, which has a large opening space and excellent ventilation , ventilation and lighting, permeability resistance, high sealing performance, excellent sound insulation performance and anti-theft performance. This makes it easy to clean the outer glass of the rotary multi-leaf window sash. Background technique [0002] The traditional window structure mostly adopts inward or outward vertical switch mode, which has poor p...

AI Technical Summary

Problems solved by technology

The opening space is small, resulting in poor ventilation and lack of the function of borrowing wind from the outside

[0006] 2. The sealing performance is poor when closed, and the wind and rain can easily seep into the room from the surrounding edges of the translation window, especially from the bottom frame edge

[0007] 3. The safety and anti-theft performance is poor. Casement windows rely on rollers to slide on the window frame. There is a large gap between the upper and lower sides, which is easy to be pried up.

[0008] 4. It is difficult to clean the glass on the outside of the window sash, and it is easy to retain sanitary corners

Especially high-level cleaning work is often accompanied by danger, which can easily lead to personal safety accidents
