The two ends of the decorative plate 2 are connected with the keel assembly 1 through the buckle connection assembly and the hanging connection assembly respectively, one end of the decorative plate 2 is fixed by the hanging connection assembly, and the other end is buckled on the buckle connection piece 3 through the buckle connection assembly with the retractable buckle tongue 5, which not only facilitates the disassembly and assembly of the decorative plate 2, ensures that the buckle connection assembly will not be loose and invalid due to frequent disassembly and assembly, but also ensures the buckle connection reliability of the buckle connection assembly, prevents the decorative plate 2 from tilting or falling, and improves the use experience.

[0027] In actual operation, the decorative plate 2 is first connected with the keel assembly 1 through the hanging connection assembly at one end, and then connected with the keel assembly 1 through the buckle connection assembly at the other end, so that both ends of the decorative plate 2 are fixed below the keel assembly 1 and ensure that the adjacent decorative plates 2 are smoothly spliced to form a decorative surface.

[0028] During installation, first, the hook body 18 and the buckle 4 are fixed at the two end edges of the top surface of the decorative plate 2 respectively, and the buckle connection piece 3 is installed below the keel assembly 1, and the distance between the adjacent buckle connection pieces 3 matches the size of the decorative plate 2;

[0029] Then, the decorative plate 2 is swung to an inclined posture with the hook body 18 higher than the buckle 4, the decorative plate 2 moves upward and moves the hook body 18 above the hook groove 19 and falls into the hook groove, so that the hook body 18 and the hook groove 19 are connected;

[0030] Then, the shell 8 is moved to the vertical plate 13 and positioned by penetrating the vertical part through the perforation, the bottom of the magnet 14 is attracted to the shell 8 and ensures that the vertical part is fixed, so that the buckle tongue 5 is moved to the elongation position under the driving of the main spring 9;

[0031] Then, the end edge of the decorative plate 2 provided with the buckle 4 is lifted upward, the buckle tongue 5 is in contact with the bottom surface of the buckle connection piece 3 through the inclined surface and generates a driving force to compress the main spring 9, the main spring 9 is contracted to accumulate the pre-tightening force, and the buckle tongue 5 is retreated to the contraction position and avoids the buckle connection piece 3;

[0032] Finally, when the end edge of the decorative plate 2 is lifted into position and the buckle tongue 5 moves above the buckle platform 6, the buckle tongue 5 is reset to the elongation position under the driving of the main spring 9 (as shown in Figure 3 ), so that the buckle tongue 5 is lapped on the buckle platform 6 through the horizontal surface.

[0033] After installation, the two end edges of the decorative plate 2 are respectively fixed and positioned by the hooking assembly and the buckling assembly, so that the adjacent decorative plates 2 are horizontally arranged and can be smoothly spliced to form a decorative surface.

[0034] In actual operation, the assembly of the fastener 4 is completed by the following steps:

[0035] First, the inner end of the buckle tongue 5 is exposed after passing through the main spring 9 and the limiting ring 10 in sequence and is fixed with the limiting cover 12, so that the main spring 9 is sleeved on the buckle tongue 5 and is clamped and limited by the limiting ring 10 and the clamping ring 11; then, the auxiliary spring 16 is inserted into the installation blind hole 15, and the end of the auxiliary spring 16 is exposed from the shell 8; then, the shell 8 is slid along the guide rail 20 to the vertical plate 13, the auxiliary spring 16 is compressed into the installation blind hole 15, the outer end of the buckle tongue 5 is across the vertical plate 13 and is kept in the elongated position; finally, the magnet 14 is installed, the vertical part of the magnet 14 passes through the perforation and cooperates with the vertical plate 13 to clamp the shell 8, so that the auxiliary spring 16 is in a compressed state.

[0036] The completed fastener 4 is installed on the decorative plate 2 by passing through the fastener of the base 7, so as to be used in cooperation with the buckling part 3.

[0037] When it is necessary to disassemble the decorative plate 2, an external magnetic member is used, the magnetic attraction force between the external magnetic member and the magnet 14 is greater than the magnetic attraction force between the magnet 14 and the shell 8, so that the external magnetic member can drive the magnet 14 to overcome the attraction of the shell 8 and move in a predetermined direction. The external magnetic member is placed below the magnet 14 and is attracted downward to move downward, the vertical part moves downward and loses the limiting action on the shell 8, so that the shell 8 can be driven by the auxiliary spring 16 to move along the guide rail 20 and make the buckle tongue 5 horizontally move to be vertically dislocated from the buckle platform 6. The end edge of the decorative plate 2 can fall downward by its own gravity and be separated from the buckling part 3, and then the hook body 18 at the other end of the decorative plate 2 is separated from the corresponding buckling part 3, so as to achieve the purpose of disassembling the decorative plate 2.

[0038] In actual operation, the relative positions among the buckle tongue 5, the shell 8 and the buckle platform 6 can be changed to achieve different purposes in different scenes, including:

[0039] Scene one, when the decorative plate 2 is installed and the buckle tongue 5 needs to be buckled to the buckle platform 6, the buckle tongue 5 and the shell 8 are switched to the contracted position by relative motion (as shown in Figure 4 ), so as to avoid the buckle platform 6 and move above the buckle platform 6, so as to facilitate the buckle tongue 5 to be lapped on the buckle platform 6 after being reset to the elongated position;

[0040] Scene two, when the installed decorative plate is disassembled, the vertical part of the magnet 14 falls down and releases the limiting of the shell 8, the relative positions between the buckle tongue 5 and the shell 8 are fixed, the buckle tongue 5 slides along the guide rail 20 together with the shell 8 and is separated from the buckle tongue 5 (as shown in Figure 5 ).

The fastening tongue 5 can switch and move between the contraction position avoiding the fastener 3 and the extension position lapped on the fastening table 6. The contracted fastening tongue 5 drives the main spring 9 to compress and accumulate pre-tightening force, so that the fastening tongue 5 can return by extension under the driving of the pre-tightening force. The length of the main spring 9 satisfies the return of the fastening tongue 5 to the extension position, ensuring that the fastening tongue can be lapped on the fastening table 6 and play a role in suspending and supporting the decorative plate 2.

[0043] In actual operation, the housing 8 is provided with a channel penetrating and guiding the telescopic movement of the fastening tongue 5. The top surface of the outer end of the fastening tongue 5 is an inclined surface, and the bottom surface is a horizontal surface.
