Novel middle-spindle rotating type multi-hinge window

Abstract

The invention discloses a novel middle-spindle rotating type multi-hinge window, which comprises a sash of the multi-spindle window which can rotate for 120 degrees, wherein the sash is rotatablely supported on a window frame on two sides through a middle spindle (a spindle in the middle). An opening and closing locking device comprises a rocker arm 2, a ratchet-gear wheel 3, an elastic pin 7, a spring bolt 4, a chute, a rotary connecting rod 5 and a sash frame groove 6, wherein the rocker arm 2 and the ratchet-gear wheel 3 are fixedly connected with the middle spindle; the elastic pin 7 is arranged according to the ratchet-gear wheel 3 and is used for clamping the ratchet-gear wheel 3; the spring bolt 4 is arranged on the inner side of the wind bar of the window frame of the multi-hinge window, and the chute corresponds to the spring bolt and is used for allowing the spring bolt to slide; one end of the rotary connecting rod 5 is rotatablely supported on the bottom of the window frame by a shaft, and the other end of the rotary connecting rod 5 is connected with the spring bolt; and the sash frame groove 6 and the chute used for allowing the spring bolt to slide of the window frame of the multi-hinge window are arranged on the same side and are correspondingly arranged. The spring bolt is lifted and lowered by rotating the rotary connecting rod near the position vertical to the window frame edge, and therefore the sash is locked at the opening or the closing state. The novel middle-spindle rotating type multi-hinge window has the advantages of big opening space and high sealing performance and anti-theft performance. In addition, glass on the outer side is convenient to clean.

Description

technical field [0001] The present invention relates to the field of construction, in particular, the present invention relates to a door and window structure of a building, more specifically, the present invention relates to a novel central axis rotating multi-leaf window, the novel central axis rotating multi-leaf window, the new The central axis rotary multi-leaf window can be used as a 120° horizontal or vertical rotary switch. It has a large opening space and has excellent ventilation, ventilation and lighting, permeability resistance, high sealing performance, excellent sound insulation performance and anti-theft performance. . The outer glass of the novel central axis rotating multi-leaf window sash is easy to clean. Background technique [0002] The traditional window structure mostly adopts inward or outward vertical switch mode, which has poor penetration resistance, sealing performance and sound insulation performance, and low anti-theft performance at the same t...

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
