Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, the plastic-steel fireproof door window comprises a window frame 1 and a window sash 2, wherein the window frame 1 is formed by splicing an upper frame 11, a lower frame 12 and two vertical frames 13 end to end. Referring to fig. 3, a rotating shaft 21 is fixedly disposed in the window sash 2 along a vertical direction, and upper and lower ends of the rotating shaft 21 penetrate through the window sash 2 and penetrate into the upper frame 11 and the lower frame 12, so that the window sash 2 can rotate around the rotating shaft 21. The top of axis of rotation 21 stretches into the interior part of last frame 11, and coaxial fixed gear 22 that is provided with slides along self length direction in the frame 11 and is provided with rack 3, and gear 22's one end fixedly connected with pressure spring 33 is kept away from to rack 3, the one end and rack 3 fixed connection, the other end and last frame 11 fixed connection of pressure spring 33 for drive rack 3 moves to gear 22 direction.

As shown in fig. 2 and 3, a pull rope 32 for fixedly pulling the rack 3 at a position away from the gear 22 is fixedly connected to one end of the rack 3 close to the compression spring 33, and the pull rope 32 is made of a nylon rope. The upper frame 11 is provided with a through hole 31 penetrating into the upper frame 11 near the indoor side wall, and one end of the pull rope 32 far away from the rack 3 penetrates through the through hole 31 and is fixedly connected to the outer side wall of the upper frame 11. Fixedly connected with on the lateral wall that rack 3 is close to gear 22 connects rope 47, a plurality of pulleys 48 of fixedly connected with in the window frame 1, connect the movable end that rope 47 kept away from rack 3 and wind and establish on pulley 48 to through pulley 48 after changing to, stretch into in lower frame 12. The movable end of the connecting rope 47 is connected with a limiting component 4 for limiting the window sash 2 in a closed state.

As shown in fig. 2 and 4, the limiting component 4 includes a rib 41, an insertion block 42, a spring 43, and a limiting member. The top wall of the lower frame 12 is provided with a through hole 44 penetrating into the lower frame 12, and the insertion block 42 is slidably arranged in the through hole 44. The spring 43 is provided with one end of the insertion block 42 extending into the lower frame 12, and two ends of the spring 43 are respectively fixedly connected with the insertion block 42 and the lower frame 12 and used for driving the insertion block 42 to extend out of the through hole 44. The limiting member is a connecting rope 47, and the connecting rope 47 is fixedly connected to the lower end of the insertion block 42, so that when the rack 3 is pulled and pulled away from the gear 22, the insertion block 42 is pulled by the connecting rope 47, and the insertion block 42 is in a state of being accommodated in the through hole 44 against the acting force of the spring 43. The elastic force of the compression spring 33 is much larger than that of the spring 43.

As shown in fig. 2 and 4, the insertion block 42 extends out of one end of the through hole 44, and the edge near the outside of the room is provided with an inclined surface 46 for laterally pressing the insertion block 42 into the through hole 44 when the window sash 2 is closed. The inserted block 42 is close to and fixedly provided with shifting block 5 on the indoor lateral wall, and lower frame 12 is close to and has seted up along vertical direction on the indoor lateral wall and opened the bar hole 51 that wears to lower frame 12 in, and shifting block 5 wears out the bar groove to can slide from top to bottom in the bar groove. The inner wall of the window frame 1 is fixedly provided with a circle of flanges 41 along the circumferential direction, and the flanges 41 are close to the indoor position. A ring of asbestos sealing layer 7 made of asbestos is fixedly arranged on the side wall of the flange 41 close to the outdoor space. The bottom wall of the window sash 2 is provided with an insertion groove 45 for inserting the insertion block 42, and when the window sash 2 is attached to the asbestos sealing layer 7, the insertion groove 45 is aligned with the through hole 44.

As shown in fig. 2 and 5, two layers of refractory glass 6 are arranged in the window sash 2, the material of the refractory glass is toughened glass, the toughened glass and the window sash 2 are bonded together through a fireproof sealant 8, and the fireproof sealant 8 is a single-component, water-based and acrylic acid expansion type fireproof sealant 8. And a support rod 61 with two ends fixedly connected with the window sash 2 is arranged between the two layers of fire-resistant glass 6 and used for enhancing the wind pressure resistance of the window sash 2.

The specific working process is as follows: when a user fails to close the window sash 2 and a fire occurs in a room, the fire expands to rise from the window to a high-rise building, and the flame blows the pull rope 32 which penetrates through the upper frame 11 of the window frame 1. After the pull rope 32 is blown, the rack 3 connected with the pull rope 32 pushes the rack 3 to move towards the gear 22 under the action of the pressure spring 33, and drives the gear 22 to rotate after being meshed with the gear 22, so that the window sash 2 in the opening state rotates towards the closing state.

And when the rack 3 moves towards the gear 22, the connecting rope 47 is loosened, so that the inserting block 42 in the lower frame 12 extends out of the through hole 44 in the lower frame 12 under the action of the spring 43. After the window frame 1 is closed by the window sash 2, the insertion groove 45 at the bottom of the window sash 2 is aligned with the through hole 44, the insertion block 42 is inserted into the insertion groove 45 under the action of the spring 43, so that the window sash 2 is fixed, and the window is automatically closed when the fire is expanded. Effectively avoid the intensity of a fire to high-rise floor and reduce the loss that the conflagration caused.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
