[0037] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0038] Before installing the elevator door cover, it is necessary to measure the size of the elevator door frame and adjust the height adjustment mechanism 9 and the width adjustment mechanism 17 according to the size of the elevator door frame. When it is necessary to adjust the overall height of the side panel assembly, a flat-blade screwdriver can be inserted into the slot 908 and the end of the plug plate 904 can be pushed into the fixed socket 906. At this time, the driving wheel 907 is unlocked, and then the flat-blade screwdriver is rotated. The flat-blade screwdriver drives the driving wheel 907 to rotate, and the driving wheel 907 will drive the adjacent first transmission wheel 909 to rotate. The first transmission wheel 909 will drive the adjacent second transmission wheel 910 to rotate, and the second transmission wheel 910 will drive another adjacent group of first transmission wheels 909 to rotate, thereby realizing the transmission of kinetic energy, so that all the second transmission wheels 910 rotate, and the side surfaces of the second transmission wheels 910 are meshed with the tooth grooves on the side walls of the first adjustment opening 18, so that When the driving wheel 907 is rotated, the driving wheel 907 will drive all the second transmission wheels 910 to push the first adjustment port 18 together to complete the position adjustment of the first adjustment plate 2, thereby realizing the adjustment of the relative position of the first set of plates 1 and the first adjustment plate 2. When the adjustment is completed, adjust the flat-blade screwdriver head to a horizontal state so that the plug plate 904 corresponds to the slot 908, and take the flat-blade screwdriver out of the slot 908. At this time, the plug plate 904 is reinserted into the slot 908 under the action of the spring 902, and the plug plate 904 re-locks the driving wheel 907 under the action of the fixed socket 906. When the driving wheel 907 is locked, all the second transmission wheels 910 will be locked together, and each group of second transmission wheels 910 will apply a group of supporting force to the corresponding position of the first adjustment port 18, thereby ensuring the stability of the first set of plates 1 and the first adjustment plate 2 after being locked;

[0039] The height adjustment mechanism 9 and the width adjustment mechanism 17 have the same structure. The width adjustment mechanism 17 is used to change the relative position between the second set of plates 6 and the second adjustment plate 5, thereby adjusting the width of the top plate assembly. Each set of folding plates 16 is fixedly connected to the second set of plates 6 or the upper cross plate 4 by bolts, so that the side plate assembly and the top plate assembly form a whole, thereby facilitating the installation of the elevator door frame;

[0040] The first decorative plate 7, the second decorative plate 8, the third connecting plate 14 and the fourth decorative plate 11 are used to decorate the surface of the elevator door frame, so that the surface of the elevator door frame will not have a metallic texture after installation. Since the first connecting plate 12 and the second connecting plate 13 are both fixedly connected to the wall surface, after the third decorative plate 10 is fixed to the surface of the first connecting plate 12 and the second connecting plate 13, the third decorative plate 10 will cover the first connecting plate 12 and the second connecting plate 13 together with the patch plate 15, thereby preventing the first connecting plate 12 and the second connecting plate 13 from being exposed to the outside, thereby improving the installation effect of the elevator door frame.

[0041] Several embodiments of the present invention are described in detail above, but the embodiments of the present invention are not limited thereto and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
