As shown in fig. 1 to 3, the present embodiment provides an elevator car roof provided with a safety window, which includes a car roof main body 1 and a safety window assembly 3. The car roof main body 1 in this embodiment is not divided into a car roof and a ceiling to save space.

The car top main body 1 is provided with an opening 15, the opening 15 is positioned below the safety window assembly 3, and when the safety window assembly 3 is opened, the opening 15 is an emergency escape channel. The car top main body 1 is provided with an acrylic light-transmitting plate 10, a fluorescent lamp 11 and a down lamp 12. The bottom surface of the car top main body 1 is provided with a plurality of first support rods 13 and a plurality of second support rods 14, and the first support rods 13 are perpendicular to the second support rods 14 so as to improve the firmness of the car top main body 1.

The ceiling surface of the car roof body 1 is provided with a support 2 around the opening 15. The support 2 extends upward from the top surface of the car roof main body 1. The safety window assembly 3 is mounted on the support 2 and covers the opening 15. The security window assembly 3 comprises a first plate 31 and a second plate 32. The first plate 31 is mounted on the support 2 at front and rear sides thereof via a pivot 4, and the second plate 32 is pivotally connected at a left side thereof to a right side of the first plate 31 via a hinge 5.

When the safety window assembly 3 is opened, the first plate body 31 and the second plate body 32 are mutually folded, so that the height in the vertical direction is reduced, the space occupancy rate is reduced, the opening of the safety window is facilitated, and the rescue is facilitated.

The support portion 2 is provided with a support step 20, and the support step 20 supports side portions of the first plate body 31 and the second plate body 32. The supporting step 20 serves to prevent the first plate 31 and the second plate 32 from rotating downward and prevent a person in the elevator from opening by mistake, and at the same time, the supporting step can support the first plate 31 and the second plate 32 and prevent the first plate 31 and the second plate 32 from deforming.

The top surface of the second plate 32 is rotatably mounted with a rotary block 7 through a rotary shaft 6. The rotary block 7 rotates on a horizontal plane with the center of the rotary shaft 6 as a center. The rotation block 7 is provided at the right portion of the second plate 32, and the end portion of the rotation block 7 is moved to the right of the second plate 32 when it is rotated.

The rotating block 7 is connected with a bolt 8. The supporting part 2 is provided with a fixing block 9, the side surface of the fixing block 9 is provided with a slot (not shown in the figure) matched with the bolt 8, and the bolt 8 is driven to be matched with or separated from the slot when the rotating block 7 rotates. To facilitate the separation of the plug 8 from the socket, the socket is larger in size than the plug 8. When the elevator is in emergency, the bolt 8 is separated from the slot by rotating the rotating block 7, and at the moment, the first plate body 31 and the second plate body 32 can rotate.

Waist-shaped holes (not shown in the figure) are arranged at the front side and the rear side of the supporting part 2 in a penetrating way, the pivot 4 is movably arranged on the waist-shaped holes, a groove 16 is arranged on the supporting part 2, and the groove 16 is positioned between the two waist-shaped holes. So that the first plate 31 can move along the waist-shaped hole. When the safety window is opened, the first plate body 31 moves leftwards along the kidney-shaped hole, so that the openable distance is increased without increasing the lengths of the first plate body 31 and the second plate body 32, and the size of the escape opening is increased.

Two ends of the pivot shaft 4 penetrate through the waist-shaped holes, two ends of the pivot shaft 4 are connected with pull ropes 17, the top surface of the supporting part 2 is provided with a sliding groove 18, and a sliding block 19 is slidably arranged on the sliding groove 18. When the bolt 8 is matched with the slot, the rotating block 7 abuts against one side of the sliding block 19, the pull rope 17 is sleeved on the other side of the sliding block 19, the pull rope 17 is in a tensioning state at the moment, the pivot 4 is tensioned, and the first plate body 31 is prevented from sliding leftwards in a normal use state of the elevator. In order to prevent the pulling rope 17 from deviating from the sliding block 19, an arc-shaped groove is arranged on the sliding block 19.

As a further preferred feature of the above-mentioned technical solution, the second plate 32 is provided with a handle 21 for facilitating rotation of the plate 32.

As a further preferred of the above technical solution, the rotating block 7 is provided with a poke rod 22, the poke rod 22 extends upwards from the top surface of the rotating block 7, and the poke rod 22 is used for facilitating the rotation of the rotating block 7 by the maintenance personnel, increasing the convenience of operation and improving the efficiency of opening the safety window assembly 3.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all of which utilize the equivalent structure or equivalent flow transformation made by the content of the specification of the present invention, or directly or indirectly applied to other related technical fields, all included in the same way in the patent protection scope of the present invention.
