[0015] Preferably, a retaining ring is connected to the expansion sleeve, and the retaining ring is arranged between the barbs and the expansion sleeve.

[0016] Preferably, a positioning hole for positioning the metal plate is provided on the cement substrate, and a positioning column for cooperating with the positioning hole is provided on the metal plate.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] In the utility model, the diameter of the mounting hole is slightly smaller than the diameter of the expansion sleeve. After the expansion sleeve is clamped in the mounting hole, the sliding part threadedly connected to the expansion sleeve is rotated to horizontally move the sliding part in a direction away from the mounting hole. The protruding part, which is an integrally formed structure with the sliding part, drives the expansion sleeve to expand outwards under the drive of the sliding part and then presses against the mounting hole. Then, the end of the sliding part away from the mounting hole moves to the outside of the mounting hole.

At this time, the spring connecting the locking part and the composite board body is compressed; when the card block moves to the left side of the card groove, the locking part is rotated to make the card block contact with the card groove after rotation. When the card groove limits the card block, the spring in the compressed state applies a force to the locking part to resist the elastic deformation, and the locking part can press the composite board body against the wall. While being able to realize the rapid disassembly and assembly of the composite board body, compared with the prior art of installing the decorative panel on the wall by magnetic attraction, the utility model has a better fixing effect, making the connection between the composite board body and the wall more firmly;

[0020] The metal plate is adsorbed on the composite plate body by a magnetic sheet. When the metal plate is damaged or needs to be replaced with another style of metal plate, it is only necessary to directly remove the metal plate and replace it. In the utility model, the composite plate body is always connected to the wall through the expansion sleeve. When removing the metal plate for replacement, there is no need to remove the expansion sleeve and the sliding part from the mounting hole, thereby avoiding the problem in the prior art that the external magnet is used to remove the decorative plate together with the connecting rod installed on the decorative plate, and the rubber sleeve installed on the connecting rod will be severely worn during repeated disassembly, making it impossible for the decorative plate to be firmly connected to the wall.

[0036] A locking part 105 is slidably installed on the composite plate body 102, and a clamping block 118 is provided on the locking part 105; a clamping groove 106 is provided in the sliding part for limiting the locking part after cooperating with the clamping block 118; a spring 117 is rotatably installed on the composite plate body 102, and the locking part 105 is connected to the composite plate body 102 via the spring 117; a magnetic sheet 109 is installed on the composite plate body 102, and the magnetic sheet 109 is used to adsorb the metal plate 110.

[0037] In the present invention, the diameter of the mounting hole 103 is slightly smaller than the diameter of the expansion sleeve 108. After the expansion sleeve 108 is clamped in the mounting hole 103, the sliding part 104 threadedly connected to the expansion sleeve 108 is rotated to make the sliding part 104 move horizontally in the direction away from the mounting hole 103. The protrusion 107 provided with the sliding part 104 in an integrally formed structure drives the expansion sleeve 108 to expand outward under the drive of the sliding part 104 and then presses against the mounting hole 103. Then, the end of the sliding part 104 away from the mounting hole 103 moves to the outside of the mounting hole 103; the spring 117 is rotatably mounted on the composite board body 102 through the bearing, and the end of the locking part 105 away from the mounting hole 103 is connected to the bearing through the spring 117; a sliding groove is provided in the sliding part 104 to slide with the block 118, and the sliding groove is connected with the clamping groove 106; when the composite board body 102 needs to be installed on the wall 101, the locking part is pressed. 105 makes the card block 118 enter the slide groove and slide towards the wall 101.

[0038] The metal plate 110 is adsorbed on the composite plate body 102 through the magnetic sheet 109. When the metal plate 110 is damaged or needs to be replaced with another style of metal plate 110, it is only necessary to directly remove the metal plate 110 and replace it. In the present utility model, the composite plate body 102 is always connected to the wall 101 through the expansion sleeve 108. When removing the metal plate 110 for replacement, it is not necessary to remove the expansion sleeve 108 and the sliding part 104 from the mounting hole 103, thereby avoiding the problem in the prior art that the external magnet is removed together with the connecting rod installed on the decorative plate, and the rubber sleeve installed on the connecting rod will be severely worn during repeated disassembly, making it impossible for the decorative plate to be firmly connected to the wall 101.

[0044] The barbs 114 are arranged in an array around the axis of the expansion sleeve 108. By arranging the barbs 114 in an array around the axis of the expansion sleeve 108, the connection effect between the expansion sleeve 108 and the mounting hole 103 can be further improved.

[0045] Further optimization, a retaining ring 115 is connected to the expansion sleeve 108, and the retaining ring 115 is arranged between the barb 114 and the expansion sleeve 108. The retaining ring 115 can prevent the barb 114 arranged on the expansion sleeve 108 from being deformed after being squeezed by the inner wall of the installation hole 103 when the expansion sleeve 108 is driven into the installation hole 103, so that the barb 114 cannot be inserted into the wall 101 after the expansion sleeve 108 is opened, which affects the connection effect between the expansion sleeve 108 and the installation hole 103.

[0046] Among them, the cement substrate 111 is provided with a positioning hole 116 for positioning the metal plate 110, and the metal plate 110 is provided with a positioning column 113 for cooperating with the positioning hole 116. The positioning column 113 is fixedly connected to the metal plate 110, and the installation efficiency of the metal plate 110 can be further improved by providing the positioning hole 116 and cooperating with the positioning column 113.
