[0039] A plurality of snap-in fasteners 200 are arranged at intervals at transverse positions on the keel 100, and the snap-in fasteners 200 can be adjusted in transverse positions on the keel 100. A transverse rear snap-in groove is arranged on the back side of the snap-in fastener 200 (the side close to the wall is called the back side), and the rear snap-in groove is snap-connected to the keel 100. A vertically arranged front snap-in groove is arranged on the front side of the snap-in fastener 200 (the side away from the wall is called the front side), and a vertically arranged snap-in profile 300 is snapped into the front snap-in groove of the snap-in fastener 200 on the same vertical plane. The snap-in profile 300 has various forms, including a single-sided snap-in profile 301 and a double-sided snap-in profile 302, and a decorative panel 400 is connected between the left and right snap-in profiles 300.

[0040] The cross-sectional shape of the keel 100 is similar to a C-shaped structure, the opening of the C-shaped structure faces the wall, and a recessed keel groove 101 is provided on the front side of the C-shaped structure along the length direction of the keel 100. The keel groove 101 is arranged in the center of the front side of the C-shaped structure, that is, the keel groove 101 is at the same distance from the top and bottom surfaces of the keel 100; the depth of the keel groove 101 is suitable to meet the following situation: when the elastic connecting section 208 bends toward the wall and contacts the bottom of the keel groove 101, the right clamping section 205 is opened, and the right end of the clamping profile 300 can be conveniently embedded in the right clamping section 205.

[0041] The snap-fit ​​fastener 200 includes a snap-fit ​​sheet 201, an upper snap-fit ​​section 202 extending from the top of the snap-fit ​​sheet 201, a rear end of the upper snap-fit ​​section 202 being bent downward, a lower snap-fit ​​section 203 extending from the bottom of the snap-fit ​​sheet 201, a rear end of the lower snap-fit ​​section 203 being bent upward, the snap-fit ​​sheet 201, the upper snap-fit ​​section 202 and the lower snap-fit ​​section 203 forming a rear snap-fit ​​groove, the cross-sectional shape of the rear snap-fit ​​groove matches the shape of the keel 100 and is slightly larger than the cross-sectional shape of the keel 100, and the rear snap-fit ​​groove The left end of the clamping piece 201 is provided with a left clamping section 204, the front end of which is bent to the right, and the right end of the clamping piece 201 is provided with a right clamping section 205, the front end of which is bent to the left to form a limiting convex strip 206, and the front end of which is extended to the right front to form a control segment 207.

[0045] The left and right ends of the decorative plate 400 are bent backward to form embedded sections, and the embedded sections are embedded in the front clamping grooves of the clamping profile 300 at corresponding positions.

[0046] A method for installing a decorative panel installation system:

[0047] First, determine the quantity, and put a suitable number of snap fasteners 200 on the light steel keel 100, and then fix the light steel keel 100 on the wall. At this time, the snap fastener 200 can be adjusted to a lateral position on the light steel keel 100, and then adjust the snap fastener 200 to a roughly lateral position, and snap-fit ​​the snap fastener 200 at this position with a snap-fit ​​profile 300. When snapping, first embed the left end of the snap profile 300 into the left snap section 204 of the snap fastener 200, and then apply force to the control segment 207 toward the wall, so that the limiting convex strip 206 can be relatively moved to the right, thereby relatively opening. The right snap-in section 205 is then embedded into the right snap-in section 205, and then the force on the control segment 207 is released, and the limiting convex strip 206 is snapped into the front surface of the right end of the snap-in base plate to complete the installation of the snap-in profile 300 on the snap-in fastener 200. During this installation process, the lateral position of the snap-in fastener 200 can be adjusted to ensure that the snap-in profile 300 and the light steel keel 100 are perpendicular to each other, and the installation of all the snap-in profiles 300 is completed, so that the distance between the left and right adjacent snap-in profiles 300 is equal to the width of the decorative panel 400, and finally the decorative panel 400 is embedded in the front snap-in groove of the snap-in profile 300.

[0048] Embodiment 1, as Figure 1 and Figure 2 As shown, four keels 100 are arranged horizontally on the wall, four vertical clamping profiles 300 are arranged on the keels 100, and three decorative panels 400 are arranged inside the clamping profiles 300.

[0049] Embodiment 2, as Fig.12As shown (the decorative panel is not shown in the figure), the wall is divided into a first part and a second part which are arranged up and down. Two keels 100 are arranged in the first part, and four vertical clip profiles 300 are arranged on the two keels 100. Three decorative panels 400 are arranged in the clip profiles 300. In the second part, two keels 100, four clip profiles 300 and three decorative panels 400 are arranged as in the first part. In order to trim the decorative panels 400, six vertical keels 100 are arranged at three positions above the first part, below the second part and between the first part and the second part. Horizontal clip profiles 300 are arranged on the six keels 100 at the three positions. The upper and lower clip profiles 300 are single-sided clip profiles 301, and the middle clip profile 300 is double-sided clip profile 302. The decorative panels 400 are installed on the clip profiles 300.

[0050] As an extension, the keel can be fixed on the wall at any angle according to actual needs. It only needs to ensure that the keel and the clip-on profile are arranged perpendicular to each other. In addition, at the edge of the corresponding decorative panel, keels and clip-on profiles with corresponding angles can be set for the edge of the decorative panel.

[0051] The above are only specific application examples of the present invention and do not constitute any limitation on the protection scope of the present invention. Any technical solution formed by equivalent transformation or equivalent replacement shall fall within the protection scope of the present invention.
