Detailed Description
In order to make the technical solution of the present utility model better understood by those skilled in the art, the technical solution of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present utility model without making any inventive effort, shall fall within the scope of the present utility model.
Referring to fig. 1 and 2, an elevator fire door of the present embodiment includes a first door panel 11, a second door, and a barrier 2 on the same plane. Wherein, baffle 2 and second door board 12 rotate to be connected to be provided with connecting piece 4 between baffle 2's top and elevator's layer lock 3, connecting piece 4 is used for being connected baffle 2 top and layer lock 3, makes when elevator door sword drive layer lock 3 action, and layer lock 3 can drive baffle 2 through connecting piece 4 and lift upwards or fall down, and connecting piece 4 in this embodiment is the preferably stay cord.
Further, the baffle 2 is parallel to the second door panel 12 and the first door panel 11, and the width of the baffle 2 is greater than 5cm. A plurality of rotating assemblies 5 are arranged between the baffle 2 and the second door panel 12, and the rotating assemblies 5 comprise a first fixed rod 51, a second fixed rod 52 and a connecting plate 53. In this embodiment, three rotating assemblies 5 are disposed between the baffle 2 and the second door panel 12, and the three rotating assemblies 5 are uniformly arranged at intervals along the length direction of the baffle 2. Wherein, the first fixed rod 51 is fixedly connected with the baffle plate 2, the second fixed rod 52 is fixedly connected with the second door panel 12, and the connecting plate 53 is positioned between the baffle plate 2 and the second door panel 12; the connection plate 53 is provided at both ends thereof with a first through hole and a second through hole penetrating in the thickness direction thereof, respectively. The first through hole is used for allowing the first fixing rod 51 to pass through, so that one end of the connecting plate 53 is rotationally connected with the first fixing rod 51; the second through hole is used for allowing the second fixing rod 52 to pass through, so that the other end of the connecting plate 53 is rotatably connected with the second fixing rod 52. When the layer door lock 3 drives the baffle plate 2 to move through the connecting piece 4, the baffle plate 2 can rotate around the second fixing rod 52 by taking the position of the second fixing rod 52 as the circle center, so that the baffle plate 2 can displace in the horizontal direction and the vertical direction.
Specifically, in this embodiment, the fireproof door of the elevator has an open state and a closed state, where the open state refers to the open state when the elevator is operating normally, and no unexpected situations such as fire disaster occur; the closed state may refer to a normal condition or the closing of the fire door in the event of a fire. In the process that the elevator fireproof door is gradually opened, the layer door lock 3 can drive the baffle plate 2 to lift upwards through the connecting piece 4, as shown in fig. 2, so that the top end of the baffle plate 2 is located above the top end of the second door plate 12, two sides of the length direction of the baffle plate 2 are located between two sides of the length direction of the second door plate 12, when the fireproof door is opened, the baffle plate 2 can be lifted upwards by the layer door lock 3 to prevent passengers from entering and exiting the car, the stroke of opening the layer door can not be increased, and the fireproof door is in an opened state when being completely opened.
When the elevator fireproof door is converted from the open state to the closed state, as shown in fig. 1, the layer door lock 3 drives the baffle plate 2 to fall downwards through the connecting piece 4 again, at this time, a part of the inner side surface of the baffle plate 2 is attached to the first door plate 11, and the rest of the inner side surface of the baffle plate 2 is attached to the second door plate 12, namely, the baffle plate 2 can shield the position of the first door plate 11 and the second door plate 12, and when the elevator fireproof door is in the closed state, the distances from the two side edges of the baffle plate 2 to the abutting positions of the first door plate 11 and the second door plate 12 are all greater than 1cm, so that gaps are generated between the first door plate 11 and the second door plate 12 due to high-temperature deformation even under the condition of fire, and the baffle plate 2 can shield the gaps, so that the outside of the fire can be avoided. In addition, in order to ensure that the baffle 2 can effectively shield the gap between the first door plate 11 and the second door plate 12 after rotating downwards, when the elevator fireproof door is set to be switched from the open state to the closed state, the horizontal displacement of the baffle 2 is larger than the distance from the side edge of the baffle 2, which is close to the first door plate 11, to the side edge of the first door plate 11, which is close to the second door plate 12, in the open state.
Further, a plurality of arc-shaped sliding grooves 21 penetrating through the thickness direction of the baffle plate 2 are formed in the baffle plate 2, a third fixing rod 6 is further arranged on the second door plate 12 corresponding to each sliding groove 21, one end of the third fixing rod 6 is fixedly connected with the second door plate 12, and the other end of the third fixing rod 6 penetrates through the sliding grooves 21. In this embodiment, three sliding grooves 21 are arranged on the baffle plate 2 at equal intervals, and when the fireproof door of the elevator is in an open state, as shown in fig. 2, the third fixing rod 3 is located at one end of the sliding groove 21 close to the first door plate 11; when the fire door of the elevator is in a closed state, as shown in fig. 1, the third fixing rod 3 is located at an end of the chute 21 away from the first door panel 11. The chute 21 can limit and fix the rotation of the baffle plate 2 around the second fixing rod 52, and the baffle plate 2 is prevented from being lifted upwards to be too high to interfere with the landing door lock 3. If the orthographic projection of the first fixing rod 51 on the second door panel 12 is set as the first position point when the elevator fireproof door is in the open state, the orthographic projection of the first fixing rod 51 on the second door panel 12 is set as the second position point when the elevator fireproof door is in the closed state, a rotating path formed by rotating the first fixing rod 51 from the first position point to the second position point is an arc line, and the radian and the length of the chute 21 on the baffle plate 2 are respectively equal to the radian and the length of the arc line. The baffle plate 2 is ensured to generate effective displacement in the horizontal direction and the vertical direction under the lifting action of the landing door lock 3, so that the baffle plate 2 can cover the gap between the first door plate 11 and the second door plate 12.
The above embodiments are only for illustrating the technical concept and features of the present utility model, and are intended to enable those skilled in the art to understand the present utility model and to implement the same, but are not intended to limit the scope of the present utility model, and all equivalent changes or modifications made according to the spirit of the present utility model should be included in the scope of the present utility model.
