[0002] An elevator is a vertical transportation tool that uses electricity to drive a car that moves up and down along guide rails, safely and efficiently transporting passengers or goods. Elevators are widely used in high-rise buildings and are an indispensable part of modern architecture, greatly improving the accessibility and convenience of buildings. In some construction sites, construction elevators are often installed to facilitate workers' movement up and down the building. Traditional construction elevator safety doors are opened and closed by hand, and after closing, both safety doors need to be locked with a bolt. However, in use, there is a risk that workers may forget to insert the bolt and lock the safety doors, which is quite dangerous and could lead to serious safety accidents. Therefore, improvements are needed to address these issues. Utility Model Content

Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0018] Depend on Figures 1 to 6 The present invention includes a safety door 1 and a safety door 2, which are symmetrically slidably installed on the slide rail of the elevator car. A first mounting plate 3 is fixedly installed on one side of the safety door 1 near the middle of the safety door 2. Two inverted n-shaped sliding rods 4 are fixedly installed on one side of the first mounting plate 3. A sliding plate 5 is slidably installed between the two inverted n-shaped sliding rods 4, and a first inverted n-shaped operating rod 6 is fixedly installed between the middle of the two inverted n-shaped sliding rods 4. A second mounting plate 7 is fixedly installed on one side of the safety door 2 near the middle of the safety door 1. A second inverted n-shaped operating rod 8 is fixedly installed on one side of the second mounting plate 7. A connecting piece 9 that is movably connected to the sliding plate 5 is fixedly installed on one end face of the second mounting plate 7. A limiting piece 10 that contacts the sliding plate 5 and the connecting piece 9 is installed on one side of the safety door 1.
[0019] A fixed baffle 11 is fixedly installed on the upper part of the two inverted n-shaped slide rods 4 on the side closest to each other, and a first spring 12 is sleeved on the surface of the two inverted n-shaped slide rods 4 on the side closest to each other. The first spring 12 is located between the sliding plate 5 and the fixed baffle 11, and the two ends of the first spring 12 are fixedly connected to the sliding plate 5 and the fixed baffle 11 respectively. Two insertion holes 13 are symmetrically opened in the middle of the sliding plate 5, and an inverted n-shaped actuating rod 14 is fixedly installed in the middle of one side of the sliding plate 5, so that the sliding plate 5 can be effectively adjusted. By holding the first inverted n-shaped operating rod 6 and the inverted n-shaped actuating rod 14 with one hand, and then moving the inverted n-shaped actuating rod 14, the sliding plate 5 is moved to slide on the surface of the two inverted n-shaped slide rods 4 and the first spring 12 is compressed.
[0020] The connector 9 includes two inverted L-shaped pins 15 symmetrically fixedly installed on one end face of the second mounting plate 7. The ends of the two inverted L-shaped pins 15 are respectively movably inserted into the interior of two insertion holes 13. A T-shaped block 16 is fixedly installed between the two inverted L-shaped pins 15. A pressing plate 17 is fixedly installed at one end of the T-shaped block 16. The pressing plate 17 is in contact with the other side of the sliding plate 5. The limiting member 10 includes two fixing blocks 18 fixedly installed on the safety door 1. A T-shaped rod 19 is movably inserted between the two fixing blocks 18. An inverted L-shaped plate 20 that contacts the pressing plate 17 and is flush with one end face of the sliding plate 5 is fixedly installed at one end of the T-shaped rod 19. A pressing block 21 is fixedly installed on the surface of the T-shaped rod 19 between the two fixing blocks 18. A second spring 22 is sleeved on the surface of the T-shaped rod 19 between the two fixing blocks 18. The two ends of the second spring 22 are respectively fixedly connected to the pressing block 21 and one of the fixing blocks 18.
[0021] Specifically, as shown in the attached diagram, when it is necessary to move and open safety door 1 and safety door 2, the operator holds the first inverted n-shaped operating lever 6 and the inverted n-shaped toggle lever 14 with one hand and the second inverted n-shaped operating lever 8 with the other hand. Then, by toggling the inverted n-shaped toggle lever 14, the operator causes the sliding plate 5 to slide on the surface of the two inverted n-shaped sliding rods 4 and compresses the first spring 12. The movement of the sliding plate 5 causes the end of the inverted L-shaped pin 15 to move out of the insertion hole 13. At the same time, the movement of the sliding plate 5 causes the inverted L-shaped plate 20 to be relatively adjusted between the first mounting plate 3 and the sliding plate 5.
[0022] At this time, the elastic restoring force of the second spring 22 will cause the T-shaped rod 19 to push the inverted L-shaped plate 20 towards the pressing plate 17, so that the inverted L-shaped plate 20 moves between the first mounting plate 3 and the sliding plate 5 and limits the sliding plate 5. At the same time, since the ends of the two inverted L-shaped pins 15 have moved out of the inside of the insertion hole 13, the safety door 1 and the safety door 2 can be moved and opened in opposite directions by the first inverted n-shaped operating rod 6 and the second inverted n-shaped operating rod 8.
[0023] When safety door 1 and safety door 2 need to be closed, the first inverted n-shaped operating lever 6 and the second inverted n-shaped operating lever 8 are still used to move safety door 1 and safety door 2 relative to each other. The relative movement of safety door 1 and safety door 2 will cause the pressing plate 17 to move between the first mounting plate 3 and the sliding plate 5, and cause the pressing plate 17 to press and move the inverted L-shaped plate 20. The inverted L-shaped plate 20 will then compress the second spring 22 through the T-shaped rod 19 and the pressing block 21, and at the same time remove the inverted L-shaped plate 20 from between the first mounting plate 3 and the sliding plate 5. At this time, the elastic restoring force of the first spring 12 will cause the sliding plate 5 to move back, so that the ends of the two inverted L-shaped pins 15 are inserted into the two holes 13. At this time, safety door 1 and safety door 2 can be firmly closed.
[0024] The Gongben elevator safety door structure features an automatic locking mechanism upon closing. This mechanism automatically locks the doors after both safety doors are closed, effectively ensuring the door's closure is secure and thus improving elevator safety. Furthermore, the elevator safety door structure is simple in design, convenient to use and operate, and its automatic locking is stable and reliable. Its performance meets the requirements for elevator safety door use.
