Technical Field

The invention relates to the technical field of doors and windows, in particular to a safe and reliable fireproof window.

Background

The fire window is a door and window product that is used for placing indoor intensity of a fire and outwards spreads, and traditional fire window generally closes to needs manual operation and just can reach the fire prevention effect, can not close by oneself when detecting the conflagration automatically.

In order to solve the problem that the traditional fire window cannot be automatically closed when a fire disaster is detected, an intelligent door window appears in the market, the automatic detection and control system is adopted to enable the window sash to be closed when the fire disaster occurs, and then the intelligent door window is high in cost.

Disclosure of Invention

In order to solve the problem that the cost of the existing intelligent door and window is high, the invention provides a safe and reliable fireproof window, which has the following specific technical scheme:

a safe and reliable fireproof window comprises a window frame, window sashes, pulleys and pull ropes, wherein one end of each window sash is hinged to the top end of the window frame through a hinge, grooves are formed in the circumferential surfaces of the pulleys, the pulleys are fixedly arranged on the upper portion of the window frame, one end of each pull rope is fixedly arranged at the other end of each window sash, the pull ropes cross the grooves of the pulleys, the fireproof window further comprises two worm gears, a worm, first connecting plates, transverse plates, connecting rods, a shell, a limit stop, a shell, a push rod, a baffle, a first elastic film and first conical spines, the first connecting plates are parallel to each other, the worm gears are rotatably connected onto the window frame through rotating shafts, the other ends of the pull ropes are fixedly arranged on the rotating shafts, the worm penetrates through the two first connecting plates and is rotatably connected into the two first connecting plates, and the worm is meshed with, one end of each of the two first connecting plates is fixedly connected with two ends of the transverse plate, one end of each connecting rod is fixedly connected with the middle of the transverse plate, a first round notch is formed in each baffle, the edge of each first elastic film is hermetically connected with the corresponding first round notch, the shell is installed on the window frame, the edge of each baffle is hermetically connected with the side wall of the inner cavity of the shell, the inner cavity of the shell is divided into an upper cavity and a lower cavity by the baffles and the first elastic films, the upper cavity and the lower cavity are not communicated, the upper cavity is filled with liquid, the connecting rods are connected with the side wall of the upper cavity in a sliding and sealing manner, the other ends of the connecting rods are located in the upper cavity, the limiting blocks are fixedly installed on the connecting rods and located in the upper cavity, the shell is located in the lower cavity, a sealed cavity is formed in the shell, and, the top rod penetrates through the top surface side wall of the sealed cavity and is in sliding sealing connection with the top surface side wall of the sealed cavity, the first cone spine is fixedly connected with one end of the top rod, the first cone spine is located right below the first elastic film, and when the paraffin expands due to heating, the first cone spine can pierce the first elastic film.

Optionally, the diameter of the ejector rod is smaller than that of the bottom surface of the first conical spike, and the diameter of the bottom surface of the first conical spike is smaller than that of the first elastic film.

Optionally, the lateral surface of the first conical spike is further provided with a plurality of grooves parallel to the generatrix direction of the first conical spike.

Optionally, the window frame, the outer shell and the shell are all made of aluminum alloy materials.

Optionally, the helix angle of the worm is less than the friction angle of the worm gear contact.

Optionally, the liquid is a lubricating grease.

The beneficial effects obtained by the invention comprise: through setting up worm wheel, worm, casing, ejector pin and first cone spine, in case the room takes place the conflagration and makes paraffin thermal expansion produce the volume change, first cone spine punctures first elastic film, can make the worm move down and break away from the worm wheel under self action of gravity, and the casement will fall under its self action of gravity, makes door and window close, blocks indoor outdoor air convection, prevents that the intensity of a fire from spreading. Because the parts such as the worm, the worm wheel, the shell, the paraffin and the like with low cost are adopted, compared with the existing fireproof window which adopts an automatic detection and control system to close the window sash when a fire disaster happens, the fireproof window has simple integral structure and lower cost. In addition, because the fire window does not adopt an automatic detection and control system, the problem of misjudgment caused by temperature data transmission errors or incapability of transmitting temperature data can be avoided, and the fire window is safer and more reliable.
