[0025] Furthermore, it should be noted that the directional terms such as left, right, up, and down used in the embodiments of this utility model are only relative concepts or references to the normal use of the product, and should not be considered restrictive. The implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] As attached Figure 1 The image shows an elevator landing door device according to this utility model, including a landing door base plate 1, a spring 2, a first hanging plate 3, and a second hanging plate 4. (See attached image.) Figure 4 As shown, the top of the landing door bottom plate 1 is bent to form a horizontal mounting plate 11, and the bottom of the landing door bottom plate 1 is bent to form a guide rail portion 12. Pulleys 5 are installed at both ends of the landing door bottom plate 1 along its length, and steel wire ropes 6 are wound around the two pulleys 5. Hanging wheels 7 and lower support wheels 8 are installed on the back of both the first hanging plate 3 and the second hanging plate 4. The hanging wheels 7 and lower support wheels 8 roll along the top and bottom surfaces of the guide rail portion 12, respectively. (See attached diagram) Figure 5 Appendix Figure 6 As shown, a first notch 31 is formed near the bottom of the first hanging plate 3, and the two sides of the first notch 31 form outwardly bent edges 312, as shown in the attached figure. Figure 2As shown, the two ends of the wire rope 6 are connected to two folded edges 312 respectively. The folded edges 312 formed by bending from the first hanging plate 3 make the overall structure simpler and more compact, eliminating the need to install additional wire rope fixing brackets on the first hanging plate 3, reducing costs, simplifying installation procedures, and improving integration.

[0027] The upper part of the second mounting plate 4 is equipped with a fixing bracket 9, as shown in the attached figure. Figure 3 As shown, the fixed base 9 is fixedly connected to the wire rope 6. A hook-shaped part 91 is installed on the fixed base 9. Several hook holes 111 are spaced apart on the mounting plate 11 away from the second hanging plate 4. One end of the spring 2 is connected to the hook hole 111, and the other end is connected to the hook-shaped part 91. The first hanging plate 3 and the second hanging plate 4 are respectively connected to the lower and upper parts of the loop formed by the wire rope 6. When the wire rope 6 rotates around the two pulleys 5, the first hanging plate 3 and the second hanging plate 4 open synchronously to both sides or move towards the center under the tension of the spring 2, realizing the opening and closing function of the elevator door. The multiple hook holes 111 facilitate adjustment of the installation position and tension of the spring 2, making the movement of the first hanging plate 3 and the second hanging plate 4 towards the center smoother and more natural.

[0028] As attached Figure 6 Appendix Figure 7 As shown, the lower part of the first hanging plate 3 and the second hanging plate 4 are machined with mounting holes, and the mounting holes have mounting shafts 10. The lower support wheel 8 is sleeved on the mounting shaft 10. The end of the mounting shaft 10 away from the first hanging plate 3 and the second hanging plate 4 has a baffle 20. The baffle 20 extends upward to the back of the guide rail 12 to prevent the lower support wheel 8 from falling off the bottom of the guide rail when the first hanging plate 3 or the second hanging plate 4 moves, making the operation safer and more reliable. The top surface of the guide rail 12 is a convex arc surface, and the bottom surface is a horizontal surface. The hanging wheel 7 forms a concave structure corresponding to the top surface of the guide rail 12, making the operation more stable and less likely to fall off. The first hanging plate 3 and the second hanging plate 4 both have a second notch 32. The edge of the second notch 32 has a folded plate 321 that bends to the side near the bottom plate 1 of the door. The end of the folded plate 321 has a hook 322 that goes around the top surface of the guide rail 12 and extends downward, further enhancing the anti-fall function.

[0029] A hook lock 21 is installed in the center of the landing door bottom plate 1. A hook plate 22 corresponding to the hook lock 21 is installed on the second hanging plate 4. A door ball 23 is installed on the hook plate 22 so that the elevator door knife can open the landing door synchronously.

[0030] In this embodiment, the distance between the top of the landing door bottom plate 1 and the bottom of the first hanging plate 3 is 132mm, which is suitable for situations where the shaft width is smaller or the floor spacing is smaller. By reducing the height of the landing door bottom plate and the door hanging plate, the structure of the entire landing door device is controlled, greatly reducing the overall height of the entire landing door device. The hanging wheel 7 is connected to the first hanging plate 3 and the second hanging plate 4 by bolts 24, which is more convenient for maintenance and has lower maintenance costs compared to the traditional riveting type on the market. The overall structure is simple and compact, meeting safety requirements while reducing manufacturing costs.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
