A matching through hole connecting the angle code slots 103 is provided in the connecting groove 102, and a connecting screw hole 62 is provided on the angle code connecting part 61. The head of the angle code bolt 7 is located in the connecting groove 102, and the screw segment passes through the matching through hole and is threadedly connected to the connecting screw hole 62, thereby realizing the combined connection of the angle code connecting part 61 and the profile body 100.

[0039] As a preferred embodiment, the inner side of the angle code connection part 61 is provided with a first avoidance groove 63 corresponding to the connection screw hole 62, and the outer side of the angle code connection part 61 is provided with a second avoidance groove 64 corresponding to the connection screw hole 62. The first avoidance groove 63 and the second avoidance groove 64 are used to reduce the weight of the connection angle code 6, and at the same time can reduce the depth of the connection screw hole 62, so as to facilitate the connection of the angle code bolt 7 in the connection screw hole 62. In addition, the angle code connection part 61 is also provided with an angle code cavity 65 located between the inner side and the outer side thereof, and the angle code cavity 65 is used to further reduce the weight of the connection angle code 6 and further reduce the production cost of the connection angle code 6.

[0040] As a preferred embodiment, the connecting angle code 6 is made of a second aluminum profile, so that the elevator manufacturer can cut a connecting angle code 6 of corresponding width on the second profile according to the width of the angle code slot 103, so that the connecting angle code 6 can be well adapted and installed in the angle code slot 103, thereby ensuring the quality of the connecting angle code 6 connecting the upper crossbeam 1, the lower crossbeam 2, the left column 3 and the right column 4; at the same time, the elevator manufacturer does not need to keep a variety of specifications of connecting angle codes 6 on hand, thereby reducing the storage cost of the connecting angle codes 6.

[0041] As a preferred embodiment, in order to facilitate assembly, the aperture of the matching through hole is usually larger than the maximum diameter of the screw section of the angle bolt 7. Therefore, during the tightening of the angle bolt 7, the profile body 100 is easily displaced, resulting in misalignment of the connection position between the upper crossbeam 1 and the left column 3, the connection position between the upper crossbeam 1 and the right column 4, the connection position between the lower crossbeam 2 and the left column 3, and the connection position between the lower crossbeam 2 and the right column 4, causing the front and rear ends of the connection points of each profile body on the rectangular door frame to be uneven, affecting the quality of the elevator door. In order to improve the quality of the rectangular door frame, the upper crossbeam 1 and the left column 3, the upper crossbeam 1 and the right column 4, the lower crossbeam 2 and the left column 3, and the lower crossbeam 2 and the right column 4 are all aligned with an L-shaped leveling plug-in 10. A leveling slot 104 is provided on the profile body 100. The leveling slot 104 is located in the profile cavity and can hide the leveling plug-in 10 to ensure the aesthetics of the elevator door. The leveling plug-in 10 includes two leveling plug-in parts 10a which are respectively inserted into two leveling slots 104. The two leveling plug-in parts 10a are integrally connected at 90 degrees. The cross-sectional shape of the leveling plug-in part 10a is the same as the cross-sectional shape of the leveling slot 104. The leveling plug-in part 10a and the leveling slot 104 are transitionally fitted or interference fit. When the two leveling plug-in parts 10a of the leveling plug-in 10 are respectively fitted in the leveling slots 104 on the two profile bodies 100, the front and rear ends of the connection position between the upper crossbeam 1 and the left column 3, the connection position between the upper crossbeam 1 and the right column 4, the connection position between the lower crossbeam 2 and the left column 3, and the connection position between the lower crossbeam 2 and the right column 4 can be as flat as possible under the constraint of the leveling plug-in 10, thereby ensuring the quality of the rectangular door frame.

[0042] The above description is only a preferred embodiment of the present invention. Any technical solution that achieves the purpose of the present invention by substantially the same means shall fall within the protection scope of the present invention.
