DETAILED DESCRIPTION
[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0019] See also Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, an elevator safety door comprises a door frame 1 and a door leaf 7. A fixing member 2 is fixedly installed on the upper front end of the door frame 1. The fixing member 2 consists of a first base rod 8 and a first fixed shaft 9. The first fixed shaft 9 has two and is symmetrically fixedly installed on the upper end of the first base rod 8. A support member 3 is arranged on the front side of the fixing member 2. The support member 3 consists of a second base rod 10 and a second fixed shaft 11. The second fixed shaft 11 has two and is symmetrically fixedly installed on the upper end of the second base rod 10. Two support arms 4 are symmetrically installed on the fixing member 2 and the support member 3. The support arm 4 consists of a rotating plate 14 and a pin 16. The rotating plate 14 has two and is rotatably connected by the pin 16. A blocking cloth 6 is fixedly installed on the front end of the first base rod 8 of the fixing member 2. The blocking cloth 6 passes through the second base rod 10 forward at the same time. The second base rod 1 0 is installed with a winding assembly 5, which consists of a winding rod 17, a blocking block 18 and an inserting rod 19. The winding rod 17 is fixedly connected to the blocking cloth 6. There are two blocking blocks 18 that are symmetrically fixedly installed at both ends of the winding rod 17, and there are several inserting rods 19 that are symmetrically fixedly installed on the outer wall of the blocking block 18. When in use, construction workers can stand under the unfolded blocking cloth 6 and wait to use the elevator. During this process, the blocking cloth 6 can block falling objects from above, thereby protecting the construction workers standing below; when the blocking cloth 6 is not needed, it can be rolled up on the winding rod 17 of the winding assembly 5, and the support member 3 can be folded toward the fixing member 2, so as to reduce the space occupied by the device, and ultimately make the elevator safety door more practical.
[0020] Furthermore, the door leaf 7 is rotatably connected to the door frame 1. When in use, the construction worker can rotate the door leaf 7 on the door frame 1 to open and close the electrical safety door.
[0021] Furthermore, the first base rod 8 on the fixing member 2 is fixedly connected to the front end of the door frame 1, and the second base rod 10 on the supporting member 3 is symmetrically provided with two insertion holes 12, and a through groove 13 is simultaneously provided on the second base rod 10 and between the two insertion holes 12, and the insertion holes 12 and the through groove 13 both penetrate the second base rod 10 front and back, and an axial hole 15 is provided on the rotating plate 14 on the supporting arm 4, and the rotating plate 14 is rotatably mounted on the first fixed shaft 9 and the second fixed shaft 11 through the axial hole 15, and the blocking cloth 6 passes through the through groove 13 provided on the second base rod 10, and the insertion rod 19 on the winding assembly 5 can be inserted into the insertion hole 12, and during use, the rotating plate 14 can be rotated with the first fixed shaft 9 and the second fixed shaft 11. The fixed axis 11 and the pin axis 16 are used as axes for rotation. When the blocking cloth 6 is not needed and the blocking cloth 6 needs to be rolled up onto the rolling rod 17 on the rolling assembly 5, and the support member 3 needs to be folded toward the fixing member 2, the support member 3 is first pushed toward the fixing member 2. During this process, the rotating plate 14 rotates with the first fixed axis 9, the second fixed axis 11 and the pin axis 16 as axes. When the support member 3 is close to the fixing member 2, the insertion rod 19 on the rolling assembly 5 is pulled out from the insertion hole 12, and then the rolling assembly 5 is rotated, so that part of the blocking cloth 6 is rolled up on the rolling rod 17. When the rolling of the blocking cloth 6 is completed, the insertion rod 19 is inserted into the insertion hole 12.
