[0052] Embodiment 2:

[0053] See also Figure 1-11 This embodiment provides a method for installing an indoor decorative wall panel based on the first embodiment, and the steps are as follows:

[0054] In the first step, the assembly plate 9 and the concave hole 4 between the two supporting base plates 1 are aligned to form the initial assembly between the two supporting base plates 1;

[0055] In more detail, firstly align the assembly plate 9 at one of the support base plates 1 with the concave hole 4 at the other support base plate 1 so that the opposite edges of the two support base plates 1 overlap;

[0056] The second step is to rotate the transmission screw 25 to move the assembly plate 9 out of the receiving groove 3 and into the concave hole 4 to wait for connection;

[0057] It can be understood that the transmission shaft 28 is rotated by the auxiliary tool, so that the transmission bevel gear 29 drives the matching bevel gear 30, thereby driving the transmission screw 25 to rotate, and the connection between the transmission screw 25 and the displacement plate 26 is coordinated, so that the displacement plate 26 pushes the displacement shaft 8 to move along the transmission screw 25, so that the assembly disk 9 is moved out of the storage groove 3, and as the displacement shaft 8 continues to slide, the assembly disk 9 can be moved into the concave hole 4;

[0058] The third step is to rotate the transmission shaft 18 to move the locking rod 11 out of the assembly plate 9 and lock it into the concave hole 4, thereby forming a lock between the two supporting base plates 1;

[0059] It can be understood that during the sliding process of the displacement shaft 8, the guide shaft 14 will slide on the outside of the transmission shaft 18. When the assembly disk 9 moves into the recessed hole 4, the driving shaft 22 is rotated to prompt the driving worm 23 to shift the matching worm gear 24, thereby driving the transmission shaft 18 and the matching worm gear 24 to rotate, and through the setting of the linkage belt 20, the power of the matching worm gear 24 can be transmitted, so that the two transmission shafts 18 rotate at the same time, and under the structural cooperation of the transmission shaft 18 and the guide shaft 14, the guide shaft 14 can slide along the transmission shaft 18, and when the transmission shaft 18 rotates, it can drive the guide shaft 14 to rotate accordingly, so that the transmission plate 16 pushes the extension plate 12. Since the extension plate 12 is supported by the locking rod 11, it can drive the locking rod 11 to move out of the assembly disk 9 and get stuck in the recessed hole 4 to form a splicing between the two supporting base plates 1;

[0060] Step 4: Magnetically attach the decorative panel body 31 to the top of the supporting base plate 1 to complete the installation of the decorative panel body 31;

[0061] It can be understood that the guide strip 35 is aligned with the reference groove 34, and the decorative panel body 31 is pressed down to move the guide strip 35 into the interior of the reference groove 34, so that the decorative panel body 31 is fitted with the top of the supporting base plate 1, and the decorative panel body 31 is adsorbed on the top of the supporting base plate 1 in conjunction with the connection between the magnet B33 and the magnet A32, thereby forming the assembly of the decorative panel body 31, and subsequently, the decorative panel body 31 can be removed from the top of the supporting base plate 1 and replaced with a decorative panel body 31 with a different pattern.

[0062] The fifth step is to install the four end corners of the spliced ​​wall panels on the indoor wall through connecting parts.
