However, the common elevator car roof safety windows are relatively cumbersome to open, and when the safety windows are opened, they will also occupy a large area, which greatly affects the rescue.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of elevator car roof safety window, including a car roof panel, a window formed on the car roof panel, a first mounting frame fixedly installed at a position closer to the right end of the upper surface of the car roof panel, a limit rod fixedly installed between the first mounting frames, a second mounting frame fixedly installed at a position closer to the left end of the upper surface of the car roof panel, a two-way threaded rod rotatably installed between the second mounting frames, one end of the two-way threaded rod passes through the second mounting frame, a hand wheel is fixedly installed on the end through which the two-way threaded rod passes, and two cover plates are arranged opposite to each other between the first mounting frame and the second mounting frame.
[0006] By adopting the above technical solution, the locking structure on the cover plate is unlocked, and then the staff rotates the hand wheel to drive the bidirectional threaded rod to rotate. When the hand wheel is rotated counterclockwise, the bidirectional threaded rod will drive both cover plates to open outward, thereby making the window on the top plate of the car fully open, and at the same time will not occupy the space used for rescue. Therefore, it is convenient for the staff to quickly open the cover plate in the event of a fire, thereby rescuing people trapped in the elevator.
[0007] Preferably, connecting blocks are fixedly installed on both side end faces of the cover plate, and through holes are opened on the connecting blocks. A limiting rod is inserted into the through hole opened in the connecting block on the right side of the cover plate, and a bidirectional threaded rod is inserted into the through hole opened in the connecting block on the left side of the cover plate.
[0008] By adopting the above technical solution, a bidirectional threaded rod is inserted into the through hole of the connecting block on the left side of the cover plate, so that it is convenient for the bidirectional threaded rod to drive the cover plate to open and close, and then a limit rod is inserted into the through hole of the connecting block on the right side of the cover plate, so when the two cover plates are opened or closed, the limit rod can maintain good stability during the switching process, and then the first mounting bracket and the second mounting bracket respectively support the limit rod and the bidirectional threaded rod, so that the cover plate can be smoothly opened and closed during the switching process.

[0012] By adopting the above technical solution, the notch formed on the inner end surface of the connecting rod will cause the connecting rod to slide outward when the insertion rod is inserted into the insertion hole, and then the spring at the outer end of the limit plate will drive the connecting rod to reset.
[0013] Preferably, two oppositely arranged fixing blocks are fixedly mounted on the cover plate at the upper and rear ends of the car roof, an inserting rod is fixedly mounted on the front end surface of the fixing block, and a limiting hole is provided on the inserting rod.
[0014] By adopting the above technical solution, the insertion rod installed on the front end surface of the fixed block on the rear end car top plate will be inserted into the insertion hole opened in the locking block. Since the inner ends of the connecting rods are provided with notches, when the insertion rods are inserted into the insertion holes, the notches opened on the connecting rods will cause the connecting rods to slide outward so that the insertion rods are fully inserted into the locking block, thereby locking the two cover plates.
[0015] Compared with the prior art, the beneficial effects of the present invention are:
[0016] 1. This new elevator car roof safety window unlocks the locking structure on the cover plate, and then the staff rotates the hand wheel to drive the two-way threaded rod to rotate. When the hand wheel is rotated counterclockwise, the two-way threaded rod will drive both cover plates to open outward, so that the window on the car roof is fully opened, and at the same time it will not take up the space used for rescue. Therefore, it is convenient for the staff to quickly open the cover plate in the event of a fire to rescue people trapped in the elevator.
[0017] 2. This new elevator car roof safety window is installed through the rod installed on the front end surface of the fixed block on the end car roof, which will be inserted into the socket opened in the locking block. Because the inner end of the connecting rod is provided with a notch, when the rod is inserted into the socket, the notch on the connecting rod will cause the connecting rod to slide outward. When the rod is fully inserted into the locking block, the spring will drive the connecting rod to reset, so that the connecting rod is inserted into the limit hole, thereby locking the two cover plates.

[0027] Working principle: When it is necessary to open the window installed on the car roof in the elevator, the staff first unlocks the locking structure on the cover plate 8, and then the staff rotates the hand wheel 7 to make the hand wheel 7 drive the two-way threaded rod 6 to rotate. When the hand wheel 7 is rotated counterclockwise, the two-way threaded rod 6 will drive both cover plates 8 to open outwards, so that the window 2 on the car roof 1 is fully opened. Then, the through hole 10 of the connecting block 9 on the left side of the cover plate 8 is inserted with a two-way threaded rod 6. Therefore, it is convenient for the two-way threaded rod 6 to drive the cover plate 8 to open and close, and then the cover plate 8 The limit rod 4 is inserted into the through hole 10 of the right connecting block 9, so when the two cover plates 8 are opened or closed, the limit rod 4 can keep the two cover plates 8 in a good stability during the switching process.

This makes it convenient for the staff to quickly open the cover plates 8 in the event of a fire, and will not occupy the space used for rescue, thereby rescuing people trapped in the elevator.
[0028] Example 2:
[0029] Please refer to Figures 1-5, which show a new type of elevator car roof safety window. Two locking blocks 11 are fixedly installed on the cover plate 8 at the front end position of the car roof 1, and a socket 12 is provided in the locking block 11. Connecting rods 13 are inserted on both sides of the locking block 11. A pull ring 14 is fixedly installed on the outer end surface of the connecting rod 13, and a notch 15 is provided on the inner end surface of the connecting rod 13. A limiting plate 16 is fixedly installed in the middle position of the connecting rod 13, and a spring 17 is provided on the outer end of the limiting plate 16 located on the outer surface of the connecting rod 13.

[0030] Working principle: When it is necessary to open the two cover plates 8 on the car roof 1, the staff can pull the pull rings 14 on both sides of the locking block 11 to both sides, so that the connecting rod 13 is pulled out from the limiting hole 20. Then, after the connecting rod 13 is pulled out from the limiting hole 20, the two cover plates 8 are controlled to move outward, so that the cover plates 8 are opened. Then, when it is necessary to limit the two cover plates 8, the two cover plates 8 are moved by turning the hand wheel 7, and then the front surface of the fixed block 18 on the rear car roof 1 is opened. The inserted rod 19 installed on the surface will be inserted into the socket 12 opened in the locking block 11. Because the inner end of the connecting rod 13 is provided with a notch 15, when the inserted rod 19 is inserted into the socket 12, the notch 15 opened on the connecting rod 13 will cause the connecting rod 13 to slide outward so that the inserted rod 19 is fully inserted into the locking block 11. When the inserted rod 19 is fully inserted into the locking block 11, the spring 17 will drive the connecting rod 13 to reset, so that the connecting rod 13 is inserted into the limiting hole 20, so that the two cover plates 8 are locked.
