[0042] Embodiment 1

[0043] See also Figure 1 , Figure 2 The present embodiment provides a close-fitting arc-shaped closing component 100, which is used to close the edges of the wallboard 200 and the background wallpaper 300. For the convenience of structural description, the wallboard 200 and the background wallpaper 300 set on the wall 800 of the building are used as an example for structural description, with the side of the wall 800 facing the user as the front, the opposite side as the back, and the direction perpendicular to the front and back directions in the horizontal plane as the left and right directions. Each structure in the present embodiment is described with reference to the above directions.

[0044] Usually, the wallboard 200 is arranged on the left and right sides of the background wallpaper 300, and the wallboards 200 on the left and right sides are provided with the close-fitting arc closing component 100. For the convenience of structural description, the close-fitting arc closing component 100 on the left side is taken as an example for structural description. The close-fitting arc closing component 100 of this embodiment mainly includes: an arc closing part 110, a clamping part 120, a connecting and fixing part 130 and a wallpaper closing part 140. The side of the arc closing part 110 facing the right side is the outer side, and the outer side protrudes away from the direction of the wallboard 200, and the side is an arc shape. When connected to the edge of the wallboard 200, the outer side of the arc blocks the edge of the wallboard 200, so that the edge of the decorative wall structure forms a smooth transition, making the edge closing more beautiful. The decorative effect of the arc outer surface (the outer side facing the right side) of the arc closing part 110 is unified with the wallboard 200 (covered with the same decorative surface layer) or sprayed and designed in various colors. Thus, the visible surface of the arc-shaped closing portion 110 matches the front surface of the wall panel 200 in visual matching, so that the pattern and color matching on the decorative surface of the entire wall panel 200 are consistent. The clamping portion 120 is arranged at the front end of the arc-shaped closing portion 110, and an installation space that accommodates the thickness of the wall panel 200 is formed at the front end of the arc-shaped closing portion 110. After the clamping portion 120 is clamped with the clamping opening 210 on the side of the wall panel 200, the wall panel 200 is connected in the installation space; the front surface of the wall panel 200 is not concave at the front end position of the arc-shaped closing portion 110, so as to form a close fit with the surface of the arc-shaped closing portion 110, so as to reduce the influence of the splicing gap on the appearance. The connecting and fixing part 130 is arranged on the inner wall of the arc closing part 110 and is used to connect the keel 400, with the area surrounded by the arc-shaped contour of the arc closing part 110 as the inner side, so that an avoidance space 111 is formed between the connecting and fixing part 130 and the inner wall surface of the arc closing part 110, and the avoidance space 111 is used to avoid the edge of the keel 400, so as to avoid collision with the keel 400 during installation, thereby ensuring the convenience of the assembly process. The wallpaper closing part 140 is arranged at the rear end of the arc closing part 110, and is used to cover the edge front surface of the background wallpaper 300; the edge of the background wallpaper 300 is closed so that the edge of the background wallpaper 300 will not be exposed, thereby achieving a better closing decorative effect.

[0045] See also Figure 1 , Figure 2The working principle of the arc-shaped closing component 100 provided in this embodiment is as follows: the snap-fitting part 120 is matched with the snap-fitting part 210 on the side of the wall panel 200, so as to realize the snap-fitting of the wall panel 200, so that the side of the wall panel 200 is against the snap-fitting part 120 and the close-fitting effect is achieved, and the decorative effect is good. The arc-shaped closing part 110 is connected to the edge of the wall panel 200 by connecting the fixing part 130, and is sleeved on the outer side of the edge of the wall panel 200, so that the edge of the wall panel 200 can be closed, so that the edge of the wall panel 200 will not be exposed. The wallpaper closing part 140 covers the front surface of the edge of the background wallpaper 300 to close the edge of the background wallpaper 300, so that the edge of the background wallpaper 300 will not be exposed, and a better closing decorative effect is achieved. Therefore, the close-fitting and finishing effect of the wall panel 200 is achieved, and the close-fitting arc-finishing component 100 can form a standardized finished component with precise size, which can be more conveniently adapted to the wall panel 200 and can be directly plugged in and used at the construction site, thereby reducing the processing difficulty, reducing the construction steps and time, reducing the decoration cost, and greatly facilitating the decoration construction process.

[0046] See also Figure 2 , Figure 3 Furthermore, the snap-in portion 120 in this embodiment specifically includes: a snap-in baffle 121 and a snap-in plug-in plate 122. The snap-in baffle 121, the snap-in plug-in plate 122 and the arc closing portion 110 are integrally formed. The snap-in baffle 121 is connected to the front end edge of the arc closing portion 110 and extends toward the connecting and fixing portion. The snap-in baffle 121 is located on the left side of the front end of the arc closing portion 110 and extends vertically toward the rear for a predetermined distance without connecting to the connecting and fixing portion. The snap-in plug-in plate 122 is disposed at the rear end or middle position of the snap-in baffle 121 and extends toward a side away from the arc closing portion 110; the snap-in baffle 121 extends a predetermined length toward the left side, and the snap-in plug-in plate 122 is used to be plugged into the snap-in 210 on the side of the wall panel 200. The wall panel 200 is provided with snap-in slots 210 on both sides. When the snap-in slots 210 of the wall panel 200 are inserted into the snap-in plate 122, the rear surface of the wall panel 200 can be abutted against the connecting and fixing portion 130 to achieve stable support for the wall panel 200. The front surface of the wall panel 200 can be flush with the front end of the arc closing portion 110, which not only facilitates splicing but also achieves a better close splicing effect.

[0047] See also Figure 2 , Figure 3Furthermore, the connection and fixing part 130 in this embodiment includes a horizontal side plate 131, which is connected to the inner wall of the arc closing part 110 and extends to the left side to set a predetermined length. The horizontal side plate 131 and the arc closing part 110 are integrally formed, which is convenient for processing. The horizontal side plate 131 is used to be fixed to the keel 400 on the inner side of the wall panel 200 by screws. In this way, the arc closing part 110 is fixed to the wall 800 through the keel 400.

[0048] Furthermore, in this embodiment, the horizontal side plate 131 is provided with abutting bosses 132, which are formed by bending the sheet metal of the horizontal side plate 131, and the rear surface of the abutting bosses 132 is used to abut against the surface of the keel member 400. The abutting bosses 132 abut against the keel member 400, providing a support position for the fixation of the horizontal side plate 131, and the contact with the surface of the keel member 400 only occupies a small part of the horizontal side plate 131, thus avoiding the contact between the surface of the entire horizontal side plate 131 and the surface of the keel member 400, thereby avoiding the problem of unstable surface-to-surface connection caused by the overall uneven surface of the keel member 400.

[0049] The front side of the boss 132 is concave due to the bending of the sheet metal to form a groove 133, and the groove 133 is used to accommodate the screw head. When the screw passes through the horizontal side plate 131 and is driven into the keel member 400, the screw head can be in the groove 133 without protruding, and will not affect the installation of the wall panel 200.

[0050] Furthermore, in this embodiment, a support platform 135 is provided at one end of the horizontal side plate 131 away from the arc closing portion 110. The support platform 135 is located at the left end of the horizontal side plate 131. The support platform 135 is spaced apart from the abutting boss 132. The support platform 135 is used to abut against the surface of the keel member 400. The support platform 135 is used to abut against the keel member 400 to achieve stable support for the horizontal side plate 131.

[0051] Furthermore, in this embodiment, a screw groove 134 is provided on the side of the abutting boss 132 away from the keel member 400. The screw groove 134 is a V-shaped groove, and the screw is directly driven into the horizontal side plate 131 at the screw groove 134, so that the screw is accurately driven into the position and the screw is not easy to be tilted.

[0052] Furthermore, one end of the horizontal side plate 131 in this embodiment is connected to the arc top position of the inner wall of the arc closing part 110. The arc top position of the inner wall of the arc closing part 110 has a high structural strength, and the pressure bearing capacity of the arc top position is strong. The connection structure of the horizontal side plate 131 and the arc closing part 110 is stable and not easy to break.

[0053] See also Figure 2 , Figure 3 Furthermore, the wallpaper closing portion 140 in this embodiment specifically includes: a vertical connection plate 141 and a closing side plate 142. The vertical connection plate 141, the closing side plate 142 and the arc closing portion 110 are integrally formed. The vertical connection plate 141 is connected to the end (the leftmost end) of the rear part of the arc closing portion 110, and extends toward the background wallpaper 300; the vertical connection plate 141 extends a predetermined length toward the rear, and is connected to the closing side plate 142 at the end, and the closing side plate 142 is vertically connected to the end of the vertical connection plate 141 away from the arc closing portion 110, and extends a predetermined length toward the right side. A light strip groove 143 is formed between the vertical connection plate 141 and the closing side plate 142, and the light strip groove 143 is used to install the light strip 700. The light strip groove 143 provides an installation position for the light strip 700, so that the light strip 700 can be blocked by the arc closing portion 110, thereby hiding the light strip 700. The light strip groove 143 is a prefabricated size. When the light strip 700 is installed in the light strip groove 143, the fixing angle of the light strip 700 is accurate, which can ensure that the light of the light strip 700 is irradiated from the side to achieve a diffuse reflection decorative effect. The closing edge plate 142 is pressed on the front surface of the background wallpaper 300 to cover the background wallpaper 300. The gap between the closing edge plate 142 and the background wallpaper 300 can be glued to achieve a beautiful closing effect.
