Description

Technical Field

[0001] The invention relates to a bottom-hung window. Background Art

[0002] According to the new technical specifications for building smoke prevention, in order to ensure that the natural smoke exhaust windows can be opened smoothly and in time during a fire, the smoke exhaust windows should be electric smoke exhaust windows with the function of centralized manual opening on site. At the same time, as building doors and windows, smoke exhaust windows need to be equipped with multi-point locks in daily use to meet the requirements of air tightness and water tightness of the window sashes and the risk of preventing high-altitude windows from falling. Therefore, a suitable smoke exhaust window should meet the following conditions at the same time: 1. The smoke exhaust area is the largest and the effect is the best. 2. It should have a manual release function for emergency manual opening in case of power failure. 3. Since there are many windows in a building, they need to be opened manually in different areas according to the requirements of fire protection. 4. In order to solve the air tightness and water tightness of the window sashes and prevent the risk of falling from high altitudes, more than two multi-point locks need to be set. In the prior art, patents such as announcement number CN205259823U "Vertical Sliding Window Multilateral Lock Structure" and announcement number CN103075074B "Intelligent Vertical Opening Side Window" disclose a vertical sliding window that slides vertically and has the function of manually opening for fire fighting and smoke exhaust. However, when insulating glass is installed, the vertical window will fall directly once manually released under the action of greater gravity. When multiple windows fall together, there is a great safety hazard. Moreover, due to the poor sealing performance of the sliding structure window, it is difficult to meet the energy-saving requirements of building doors and windows. Summary of the invention

[0024] The releasable device of "worm gear and transmission gear" comprises a hollow shaft, a worm gear and a transmission gear arranged on the hollow shaft, and the transmission gear is a releasable gear.

[0025] The pneumatic unlocking linkage device is characterized in that: the cylinder body is fixed on the movable frame, and the piston rod is connected to the connecting rod. When the manual window opening mode is required, the piston rod is driven to extend and retract, so that the inclined pressure block is pressed into the push rod, and the push rod drives the sliding key to disengage from the above-mentioned releasable gear, and the releasable gear is in a free release state, thereby realizing the manual window opening mode.

[0026] The pneumatic unlocking linkage device, when the window needs to be set with a locking point 18, needs to be set with two cylinders, the two cylinder bodies are connected as one, one piston rod is fixed on the movable frame, and the other piston rod is connected to the inclined pressure block and the locking point on the movable frame through a connecting rod. By driving the piston rod, the locking point on the movable frame can be unlocked, and at the same time, the inclined pressure block presses into the push rod, and the push rod drives the sliding key to disengage from the above-mentioned releasable gear, and the releasable gear is in a free release state, realizing the manual window opening mode.

[0027] In order to realize the function of collective manual release and opening of multiple windows, the pneumatic unlocking linkage device is characterized in that the cylinder is connected to the air tank through an air pipe, and a manual opening valve is provided on the main air circuit connecting the multiple cylinders and the air tank. In an emergency state, the manual opening valve is opened, and the multiple cylinders on the main air circuit drive the piston rod to put the releasable gears of the multiple lower-hung windows in a freely released state, thereby realizing a collective manual window opening mode.

[0029] The manually-automatically-openable bottom-hung window can be provided with two manually-openable electric window openers on both sides of the window, and a connecting rod is connected at the corner by a corner turner 20.

[0030] In order to further solve the problem that when the window is manually released to open, the movable frame needs an opening force in the vertical direction, and then the movable frame will accelerate to fall under the action of gravity; according to the manually and automatically openable bottom-hung window as described in claim 1, a damper 21 is connected between the fixed frame and the movable frame, and the damper consists of a cylinder body, a left spring located on the left side of the piston in the cylinder body, a piston and a telescopic rod; the left spring provides an opening force when the window is closed, and the window is first popped open during the window opening process; the telescopic rod is fixed on the piston, and a right spring is arranged between the piston and the cylinder body and located on the right side of the piston. During the window opening process, the window accelerates to fall, and the right spring is compressed to provide an opposite force to slow down the falling speed of the window.

[0032] The opening angle between the movable frame and the fixed frame is 70°, which is conducive to smoke exhaust and heat dissipation.
