[0002] With the acceleration of urbanization and the increasing number of high-rise buildings, elevators, as an important vertical transportation tool, play a vital role in ensuring the safety of people. The elevator entrance and exit are equipped with car doors, which are integrated with the elevator car and move synchronously with the car as it moves up and down. The car door consists of door panels, door locks, door lock seats, door lock latches, and other components. At the same time, a hall door is also installed at the entrance of each floor. The hall door consists of door panels, guide rails, pulleys, sliders, door frames, sills, and other components.

[0003] As elevator hall doors are always on the outside, they are easily impacted by external objects during use, which can lead to wear, deformation, and tilting of the door panels. This can cause the bottom of the door panel to scrape against the sill when closing, resulting in low stability and safety of the elevator hall doors.

[0004] Therefore, it is necessary to invent a safe and stable elevator door to solve the above problems. Utility Model Content

[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0033] This utility model provides, for example Figures 1 to 4 The diagram illustrates a safe and stable elevator door, comprising an elevator shaft 1. An entrance / exit 11 is provided on the front inner wall of the elevator shaft 1. Two sets of opposing sliding door panels 2 are located on the front inner wall of the elevator shaft 1, inside the entrance / exit 11. Guide components are provided on the sides of the sliding door panels 2, including a guide rail frame 12, a sill 13, support rods 14, sliders 21, pulleys 22, support sleeves 23, and positioning strips 24. Multiple sets of support sleeves 23 are fixedly connected inside the sliding door panels 2. Multiple sets of support rods 14 are fixedly connected to the inner walls of the left and right sides of the elevator shaft 1. The support rod 14 is internally slidably connected to the support sleeve rod 23. The guide rail frame 12 is fixedly connected to the inner wall of the front side of the elevator shaft 1 at the position above the entrance / exit 11. The sill 13 is fixedly connected to the inner wall of the front side of the elevator shaft 1 at the position below the entrance / exit 11. Two sets of sliders 21 are fixedly connected to the upper end of the movable door panel 2. Two sets of pulleys 22 are rotatably connected to the sides of the two sets of sliders 21. The two sets of pulleys 22 are respectively locked on the upper and lower sides of the guide rail frame 12. Two sets of positioning strips 24 are fixedly connected to the lower end of the movable door panel 2. The positioning strips 24 are slidably connected to the positioning grooves on the surface of the sill 13.

[0034] The movable door panel 2 is opened and closed by the elevator car door. During the opening of the movable door panel 2, the slider 21 drives two sets of pulleys 22 to slide on the upper and lower sides of the guide rail frame 12 respectively, so that the two sets of movable door panels 2 slide in opposite directions to open the entrance and exit 11. At the same time, the positioning strip 24 slides in the positioning groove on the surface of the sill 13 to limit the sliding position of the movable door panel 2 and improve its stability during the sliding process.

[0035] In addition, during use, multiple sets of support sleeves 23 support the inner side of the movable door panel 2, improving the internal structural strength of the movable door panel 2. They work in conjunction with the support rods 14 to prevent the movable door 2 from deforming during use. Furthermore, the support sleeves 23 slide on the surface of the support rods 14, and the support rods 14 further position the support sleeves 23, improving the stability and smoothness of the movable door panel 2 during sliding, and enhancing the safety of the elevator door.

[0036] See Figures 4 to 7Each of the two sets of movable door panels 2 has an equipment slot 25 at one end of its lower side that is close to each other. An installation plate 27 is fixedly connected inside the equipment slot 25. An electric cylinder 28 is fixedly installed on the side of the installation plate 27. A controller 29 is fixedly installed on the upper side of the installation plate 27. Guide slots 26 are opened on the inner walls of the front and rear sides of the equipment slot 25. A cleaning box 3 is set inside each of the two sets of equipment slots 25. The telescopic rod in the electric cylinder 28 is fixedly connected to the side wall of the cleaning box 3. Guide blocks 31 are fixedly connected to the front and rear surfaces of the cleaning box 3. The guide blocks 31 are slidably connected to the guide slots 26. An electric motor 32 is fixedly installed on the inner bottom wall of each of the two sets of cleaning boxes 3. The output end of the electric motor 32 passes through the lower wall of the cleaning box 3 and is fixedly connected to a cleaning plate 33. A cleaning brush 34 is fixedly connected to the lower surface of the cleaning plate 33. An infrared sensor 35 is fixedly connected to the surface of the two sets of cleaning boxes 3 that are close to each other.

[0037] At the same time, when the two sets of movable door panels 2 slide close together, the controller 29 starts the electric cylinder 28 and the electric motor 32. The telescopic rod in the electric cylinder 28 pushes the cleaning box 3 to the outside of the equipment slot 25. The output end of the electric motor 32 drives the cleaning plate 33 and the cleaning brush 34 to rotate, cleaning the sill 13 and the inside of the positioning slot on its surface, avoiding foreign objects remaining on the surface of the sill 13, so that the elevator door can close normally, and further improving the stability of the elevator door closing.

[0038] In addition, as the two sets of movable door panels 2 gradually approach each other, the infrared sensor 35 monitors the position between the two sets of cleaning boxes 3 in real time. When the distance between the two sets of cleaning boxes 3 is less than 5cm, the controller 29 starts the electric cylinder 28 again. The telescopic rod in the electric cylinder 28 slides the cleaning box 3 into the equipment slot 25. When the cleaning box 3 is completely moved into the equipment slot 25, the controller 29 turns off the electric motor 32, so that the cleaning brush 34 stops rotating.

[0039] The working principle of this utility model is as follows: The guide rail frame 12, sill 13, slider 21, pulley 22 and positioning strip 24 work together to support and position the upper and lower ends of the movable door panel 2. At the same time, the support sleeve 23 improves the structural strength of the movable door panel, and multiple sets of support rods 14 support the middle position of the movable door panel 2, effectively reducing the deformation of the movable door panel 2 and improving the stability of the movable door panel 2 during the sliding process, thereby effectively improving the safety of elevator use. At the same time, the telescopic rod in the electric cylinder 28 pushes the cleaning box 3 to the outside of the equipment slot 25, and the electric motor 32 drives the cleaning plate 33 and cleaning brush 34 to rotate, cleaning the surface of the sill 13, avoiding the accumulation of foreign objects on the surface of the sill 13 and affecting the normal closing of the elevator door, further improving the safety of elevator door use.
