In description of the present utility model, also it should be noted that, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should be interpreted broadly, and such as, can be fixedly connected with, also can be removably connect, or connect integratedly; Can be mechanical connection, also can be electrical connection; Can be directly be connected, also indirectly can be connected by intermediary, can be the connection of two element internals.For the ordinary skill in the art, particular case the concrete meaning of above-mentioned term in the utility model can be understood.
As shown in drawings, the utility model provides a kind of outdoor elevators 4 protective door, and elevator 4 disposed in the outdoor, near the side of building, comprises sliding door 1, turnover door 7, first fixed pulley 2, second fixed pulley 5 and stay cord 3;
Sliding door 1 is arranged on one end of turnover door 7;
Sliding door 1 and turnover door 7 are disposed on the same plane;
The turning cylinder 6 of turnover door 7 is arranged on turnover door 7 one end away from sliding door 1;
One end of stay cord 3 is fixedly connected with sliding door 1 one end near turnover door 7;
The other end of stay cord 3 is fixedly connected with turnover door 7 one end near sliding door 1;
On first fixed pulley 2 and the second fixed pulley 5 elevator 4 disposed in the outdoor;
On the outer wall that first fixed pulley 2 is vertical with building with the second fixed pulley 5 elevator 4 all disposed in the outdoor;
The upper end of the first fixed pulley 2 elevator 4 disposed in the outdoor;
The lower end of the second fixed pulley 5 elevator 4 disposed in the outdoor;
First fixed pulley 2 is greater than the first fixed pulley 2 to the distance of sliding door 1 away from one end of turnover door 7 to the distance of sliding door 1 near one end of turnover door 7;
Second fixed pulley 5 is less than the second fixed pulley 5 to the distance of turnover door 7 away from one end of sliding door 1 to the distance of turnover door 7 near one end of sliding door 1.
Before turnover door 7 and sliding door 1 elevator 4 disposed in the outdoor, simultaneously, turnover door 7 is arranged on the below of sliding door 1, any side of the left and right sides of the first fixed pulley 2 and the second fixed pulley 5 elevator disposed in the outdoor 4, in the present embodiment, the first fixed pulley 2 is less than the vertical distance of the second fixed pulley 5 to sliding door 1 to the vertical distance of sliding door 1.
When needs carry out opening outdoor elevators 4, rotate turnover door 7, turnover door 7 rotates centered by its turning cylinder 6, stay cord 3 is arranged on turnover door 7 one end near sliding door 1, that is it is arranged on the one end away from turning cylinder 6, and be less than the second fixed pulley 5 to the distance of turnover door 7 away from one end of sliding door 1 to the distance of turnover door 7 near one end of sliding door 1 due to the second fixed pulley 5, therefore, turnover door 7 is in the process of rotating, stay cord 3 length between turnover door 7 and the second fixed pulley 5, due to the invariant position of the first fixed pulley 2 and the second fixed pulley 5, stay cord 3 length between turnover door 7 and the second fixed pulley 5 will cause stay cord 3 length between sliding door 1 and the first fixed pulley 2 to shorten, and then sliding door 1 is slided to the direction of the first fixed pulley 2, then sliding door 1 is driven to rise, outdoor elevators 4 is opened.
When outdoor elevators 4 closed by needs, its whole process is contrary with said process.
It is pointed out that arranging of stay cord 3 can be common be rope, also can be steel rope, can also be other linear structures, as long as it can make turnover door 7 and sliding door 1 carry out mutual pulling.
Also it is to be noted, turnover door 7 is owing to also needing to use as escape way, therefore it is higher to the requirement of intensity, at turnover door 7, the reinforced rib 10 that several run through turnover door 7 can be set away from the side of outdoor elevators 4, improve the intensity of turnover door 7, ensure that turnover door 7 can not be damaged in as escape way.
Be preferred embodiment that the first fixed pulley 2, second fixed pulley 5 and stay cord 3 are two, are all symmetricly set on the outer wall of relative both sides of outdoor elevators 4.
As shown in Figure 3, in order to ensure that turnover door 7 and sliding door 1 are in the process overturn and slide, the carrying out that can balance, first fixed pulley 2 and the second fixed pulley 5 is all set in the left and right sides of outdoor elevators 4, and the first fixed pulley 2 and the second fixed pulley 5 are symmetrical arranged in the left and right sides of outdoor elevators 4, all by stay cord 3, sliding door 1 is connected with turnover door 7, ensure that the motion track of sliding door 1 and turnover door 7 can not deflect.
Be preferred embodiment turnover door 7 is provided with handle 9, for from external opening turnover door 7.
When whole protective door is closed, staff will enter in outdoor elevators 4, needs first to be rotated by turnover door 7 or by sliding door 1 upward sliding.Need because sliding door 1 rises the overall weight overcoming sliding door 1, its power needed can be larger, and promoting sliding door 1 rising can compare effort, not easy to operate; And when rotating turnover door 7, owing to being overturn downwards by turnover door 7, the gravity of turnover door 7 can become power-assisted during rotation, so can compare laborsaving.Therefore, when opening whole protective door, rotating turnover door 7 can be more convenient and laborsaving.
In the outside of turn-over door, namely turnover door 7 arranges handle 9 away from the side of outdoor elevators 4, can be rotated by handle 9 by pulling turnover door 7.
Being preferred embodiment that sliding door 1 is provided with falling stop device, falling for preventing the sliding door after opening 1.
The weight that weight due to sliding door 1 can give sliding door 1 one downward all the time, and then sliding door 1 is fallen, after sliding door 1 is opened, fall for preventing sliding door 1, need to be provided with falling stop device to ensure that sliding door 1 can not fall suddenly in the process of personnel by escape way, and then ensure the safety of the personnel by escape way.
Be preferred embodiment that falling stop device comprises falling stop hole 12, falling stop pin 13, falling stop spring 14 and falling stop frame 11;
