The position is adjustable, and the lower end of the decorative panel 4 is inserted into the upper end of the elevator top door frame 6. Through the cooperation of the door operator fixing bracket 2 and the door operator hanger 3 installed on the door closing machine assembly 1, it is convenient to connect and install the door closing machine assembly 1 with the shaft wall 8, improve the stability of the installation of the door closing machine assembly 1 and the shaft wall 8, and avoid interference between the top door frame and the door closing machine fixing bracket 2 while ensuring that the relative position of the installation height of the door closing machine and the door opening machine remains unchanged. This speeds up the on-site installation progress, reduces the installation difficulty, shortens the modification cycle, and improves customer satisfaction.

[0024] The gate closer bracket 3 includes a first angle steel 31 and a second angle steel 32. The first angle steel 31 is connected to the gate closer assembly 1 by a first bolt, and the second angle steel 32 is connected to the shaft wall 8 by a first expansion bolt. The first angle steel 31 and the second angle steel 32 are connected by a second bolt. The first angle steel 31 and the second angle steel 32 are provided with elongated holes 33 for the second bolt connection. During installation, the first angle steel 31 is first connected to the top of the gate closer frame using the first bolt, and then the second angle steel 32 is fixed to the shaft wall 8 using the first expansion bolt. Finally, the first angle steel 31 and the second angle steel 32 are connected through the elongated holes 33 using the second bolt. By connecting the gate closer assembly 1 to the shaft wall 8 from multiple directions, the stability of the gate closer assembly 1 installation is ensured. The elongated holes 33 allow the distance between the gate closer body and the shaft wall 8 to be adjusted by the first angle steel 31 and the second angle steel 32 to accommodate various installation sizes.

[0025] Both the first angle steel 31 and the second angle steel 32 are L-shaped structures. The first angle steel 31 has two parallel elongated holes 33. The L-shaped structure has good structural rigidity. Through the combination of bolts and expansion bolts, the door closing mechanism assembly 1 is rigidly fixed to the shaft wall 8. Compared with the flat plate structure, it has stronger resistance to bending and torsion, ensuring the overall rigidity of the hanger. The two parallel elongated holes 33 make the force more even when the second bolt is connected, avoid the angle steel from shifting during the adjustment process, ensure the horizontality of the door closing mechanism assembly 1, reduce the risk of hanger deformation, improve the stability of the door closing mechanism assembly 1 during operation, and prevent the door from shaking.

[0026] The door operator fixing bracket 2 includes a third angle steel 21 and a fourth angle steel 22. One end of the fourth angle steel 22 is welded to the door closing machine assembly 1, and the other end of the fourth angle steel 22 is connected to the third angle steel 21 by a connecting bolt. The other end of the third angle steel 21 is fixed to the shaft wall 8 by a second expansion bolt. Welding the fourth angle steel 22 to the door closing machine assembly 1 ensures the firmness of the door closing machine assembly 1 and the fourth angle steel 22. The second expansion bolt is used to achieve reliable fixation to the shaft wall 8. Door operator fixing brackets 2 are provided on both sides of the door closing machine assembly 1. Together with the back door closing machine hanger 3, they form a triangular stable structure to offset the impact force of the door closing machine assembly 1 during operation and solve the shaking problem after detaching from the door frame.

[0027] One end of the third angle steel 21 is provided with a round hole 25 for connecting bolts, and the other end of the third angle steel 21 is provided with an elliptical hole 23 for connecting second expansion bolts. The installation direction of the round hole 25 is perpendicular to the installation direction of the elliptical hole 23. The elliptical hole 23 is used to be installed and adapted to the vertical direction of the shaft wall 8 to accommodate the dimensional deviation of the shaft wall 8 at the old renovation site.

[0028] The other end of the fourth angle steel 22 is provided with a notch 24 for connecting bolts. When the third angle steel 21 and the fourth angle steel 22 are connected, the position of the third angle steel 21 can be adjusted in the front-back direction of the fourth angle steel 22. The round hole 25 of the third angle steel 21 provides a fixed reference, and the notch 24 of the fourth angle steel 22 provides an adjustment stroke. The two work together to achieve precise positioning in the front-back direction, ensuring that the installation distance between the door closing machine assembly 1 and the shaft wall is controllable. Through front-back adjustment, the distance between the car side door opening machine and the door closing machine can be precisely matched, ensuring that the relative position of the door closing machine and the door opening machine remains unchanged, without affecting the linkage between opening and closing the door, and avoiding the door jamming problem caused by the distance deviation.

[0029] The decorative panel 4 is a rectangular panel with U-shaped holes 5 on both sides of its upper end. The decorative panel 4 is connected to the door closer assembly 1 by a third bolt passing through the U-shaped holes 5. The length of the decorative panel 4 matches the width of the elevator top door frame 6, and the elevator top door frame 6 has a socket 7 for inserting the lower end of the decorative panel 4. The U-shaped holes 5 allow the decorative panel 4 to be adjusted vertically to accommodate different gap sizes between the door closer assembly 1 and the top door frame after the latter is raised. The plug-in design ensures the fit between the decorative panel 4 and the top door frame. The rectangular panel structure completely covers the gap between the door closer and the top door frame, preventing the hoistway wall 8 from being seen through the door gap inside the car. At the same time, the length matches the top door frame to ensure visual integrity.

[0030] It should be noted that the elevator landing door system is used to control the precise opening and closing of the elevator hall doors to ensure passenger safety. It includes the entrance wall, the elevator top door frame, the elevator hall doors, and the door closing mechanism assembly. The door closing mechanism assembly includes the door closing mechanism body and the door closing mechanism frame.
