[0022] Detailed Implementation

[0023] To make the technical problems, technical solutions, and beneficial effects to be solved by this disclosure clearer, the disclosure will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this disclosure and are not intended to limit this disclosure.

[0025] Please see Figures 1-5This disclosure provides a wall panel decorative cover installation structure, including: a fixing member 1 and a fastener 2. The fixing member 1 is used to be disposed between two adjacent wall panels 3 and a wall 5 or a keel 4, and is fixedly connected to the wall 5 or the keel 4. The fastener 2 is used to be detachably connected to the fixing member 1 and the decorative cover 6 installed at both ends of the joint of the two adjacent wall panels 3, respectively. The fixing member 1 has a receiving space 11 at one end near the wall 5 or the keel 4, and an opening 12 is provided at one end near the wall panel 3. The opening 12 is aligned with the joint and communicates with the receiving space 11. The fastener 2 includes a rotating head 21, a limiting head 22 and an insert rod 23. One end of the insert rod 23 is connected to the rotating head 21, and the other end of the insert rod 23 is connected to the limiting head 22. The limiting head 22 is inserted into the receiving space 11 through the joint and the opening 12. The rotating head 21 can be rotated to align with and connect with the decorative cover 6, so that the fastener 2 is in a locked state.

[0026] When the surface of the wall 5 is flat, the wall panel 3 can be directly installed on the wall 5. At this time, the fastener 1 is placed between the wall panel 3 and the wall 5 and fixedly connected to the wall 5. However, when the surface of the wall 5 is not flat enough, the keel 4 needs to be installed on the wall 5 first to level it, and then the wall panel 3 is installed on the keel 4. At this time, the fastener 1 is fixedly placed between the wall panel 3 and the keel 4 and fixedly connected to the keel 4.

[0027] The working principle of the wall panel decorative cover installation structure provided in this embodiment is as follows: the fastener 1 is set on the back of the wall panel 3 and is fixedly connected to the keel 4 or the wall 5. The joint of the adjacent wall panel 3 is aligned with the opening 12 on the fastener 1. One end of the fastener 2 connected to the limiting head 22 passes through the joint and the opening 12 from the front of the wall panel 3 and enters the receiving space 11 of the fastener 1. At this time, the rotating head 21 is just close to the wall surface of the wall panel 3. When the rotating head 21 is rotated, the limiting head 22 located in the receiving space 11 rotates together and forms a limiting fit with the opening 12, so that the fastener 2 cannot move in the thickness direction of the wall panel 3 and is in a locked state. Finally, the decorative cover 6 is snapped onto the rotating head 21, covering the entire joint and the rotating head 21, which plays a role in finishing the edge and making it beautiful.

[0028] In one embodiment, combined Figure 1 and Figure 2 In this embodiment, the fastener 1 has support protrusions on both sides of the receiving space 11 facing the wall 5 or the keel 4, and the support protrusions are of the same height. In this embodiment, the support protrusions on both sides of the fastener 1 serve as the support points of the fastener 1 on the keel 4 or the wall 5, which not only ensures the stability of the fastener 1, but also forms the receiving space 11 between the two sides.

[0029] Next, combined Figure 1 and Figure 2Specifically, the fastener 1 has a groove 13 at the end near the wall panel 3, and the outer bottom surface of the groove 13 is flush with the top of the supporting protrusion. In this embodiment, the groove 13 can serve as a nail slot. When the fastener 1 is fixedly connected to the keel 4 using a self-tapping screw 8, the head of the self-tapping screw 8 can be accommodated in the groove 13, thereby ensuring the flatness of the fastener 1 on the side near the wall panel 3. In addition, the outer bottom surface of the groove 13 is flush with the supporting protrusion, which increases the contact area between the fastener 1 and the keel 4, thereby improving the stability of the fastener 1 on the keel 4.

[0030] Secondly, combining Figure 2 For example, the inner bottom of the groove 13 is also provided with a nail line 14. When the fastener 1 is fixedly connected to the keel 4 or the wall 5, the self-tapping screw 8 can be aligned with the nail line 14 before tightening, so as to prevent the self-tapping screw 8 from slipping during the tightening process.

[0031] Finally, combining Figure 2 For example, the opening 12 is a strip-shaped hole. During installation, the strip-shaped hole is aligned with the joint of two adjacent wall panels 3 so that the fastener 1 can be quickly inserted into the opening 12 along the joint and enter the receiving space 11.

[0032] In practical applications, the fastener 1 can have multiple openings 12, so that multiple fasteners 2 can be installed, thereby achieving local point installation. This not only makes the installation steps simple and easy to operate, but also makes the installation efficient.

[0033] In one embodiment, combined Figure 3 For example, the limiting head 22 of the fastener 2 can be a limiting strip, a limiting block, or a limiting piece, etc. Figure 3 The limiting head 22 is preferably a columnar limiting strip.

[0034] First, the width or thickness of the limiting head 22 should be less than the width of the opening 12 so that it can quickly pass through the opening 12 and enter the receiving space 11; while the length of the limiting head 22 should be greater than the width of the opening 12 so that when the limiting head 22 rotates after entering the receiving space 11, the limiting head 22 cannot exit the opening 12 and is thus locked in the receiving space 11. It should be understood that the limiting head 22 can also be implemented with other structures, and this embodiment does not limit it.

[0035] Secondly, combining Figure 3 For example, the insert 23 of the fastener 2 is constructed as a long strip, such as a round rod or a rectangular rod. The radial width of the insert 23 should be less than or equal to the joint width of the adjacent wall panel 3 so that the insert 23 can pass smoothly through the joint.

[0036] Next, combined Figure 3For example, the rotating head 21 of the fastener 2 is constructed as a thin block; for instance, the rotating head 21 can be a rectangular thin block, a circular thin block, a triangular thin block, a star-shaped thin block, or an irregularly shaped thin block, etc. Figure 3 As shown, the rotating head 21 is preferably a rectangular thin block.

[0037] Specifically, the rotating head 21 is provided with a first snap-fit ​​structure 24, and the decorative cover 6 is provided with a second snap-fit ​​structure 61. The first snap-fit ​​structure 24 and the second snap-fit ​​structure 61 are snap-fitted together. Through the cooperation of the first snap-fit ​​structure 24 and the second snap-fit ​​structure 61, the rotating head 21 can be detachably connected to the decorative cover 6.

[0038] For example, combining Figure 4 and Figure 3 Specifically, the first snap-fit ​​structure 24 includes two opposing first sidewalls 241, with an inwardly extending limiting portion 242 at the top of each first sidewall 241. The limiting portion 242 includes a first limiting wall facing away from the decorative cover 6 and a first guide wall facing the decorative cover 6. The first limiting wall is perpendicularly connected to the first sidewall, and the first guide wall is angularly connected to the first limiting wall. The second snap-fit ​​structure 61 includes two opposing second sidewalls 611, with an outwardly extending connecting portion 612 at the top of each second sidewall 611. The connecting portion 612 includes a second limiting wall facing away from the rotating head 21 and a second guide wall facing the rotating head 21. The second limiting wall is perpendicularly connected to the second sidewall, and the second guide wall is angularly connected to the second limiting wall. The first sidewall 241 and / or the second sidewall 611 are elastic, and the second sidewall 611 can be snapped into the first sidewall 241 along the first guide wall, so that the first limiting wall and the second limiting wall abut against each other.

[0039] Specifically, the connection between the first limiting wall and the first guide wall on the first sidewall 241 is a planar transition, with the plane perpendicular to the first limiting wall. The connection between the second limiting wall and the second guide wall on the second sidewall 611 is a linear transition, forming a pointed structure. When the decorative cover 6 engages with the rotating head 21, the first sidewall 241 and the second sidewall 611 press against each other, causing the second guide wall to slide relative to the first guide wall and undergo elastic deformation. This allows the entire connecting part 612 to quickly slide into the limiting part 242, causing the first limiting wall and the second limiting wall to abut against each other, achieving the effect of the decorative cover 6 being secured to the rotating head 21. Furthermore, when the decorative cover 6 separates from the rotating head 21, an external force is applied to the second sidewall 611, causing it to undergo elastic deformation. This causes the first limiting wall and the second limiting wall to misalign, allowing the connecting part 612 on the second sidewall 611 to exit from the limiting part 242 on the first sidewall 241, achieving the effect of separation.

[0040] In one embodiment, combined Figure 1 and Figure 2In addition, this disclosure also provides a fastener 1, which is applied in the above-mentioned wall panel decorative cover installation structure. The fastener 1 is a block structure, which has a receiving space 11 on one side in the thickness direction and an opening 12 on the other side in the thickness direction. The opening 12 communicates with the receiving space 11.

[0041] In this embodiment, the fixing component 1 is the same as the fixing component 1 in the above-mentioned wall panel decorative cover installation structure. For specific implementation details of the fixing component 1, please refer to the above-mentioned wall panel decorative cover installation structure, which will not be repeated here.

[0042] In one embodiment, combined Figure 1 and Figure 3 In this disclosure, a fastener 2 is provided for use in the above-mentioned wall panel decorative cover installation structure. The fastener 2 includes a rotating head 21, a limiting head 22 and a plug 23. One end of the plug 23 is connected to the rotating head 21 and the other end of the plug 23 is connected to the limiting head 22. The rotating head 21 is provided with a first snap-fit ​​structure 24 that is detachably connected to the decorative cover 6.

[0043] In this embodiment, the fastener 2 is the same as the fastener 2 in the above-mentioned wall panel decorative cover installation structure. For specific implementation details of the fastener 2, please refer to the above-mentioned wall panel decorative cover installation structure, which will not be repeated here.

[0044] In addition, referring to Figure 1, the steps for installing the decorative cover 6 using fastener 1 and fastener 2 include:

[0045] Step 1: Install the leveling keel 4 onto the wall 5 using leveling bolts 7;

[0046] Step 2: Fix fastener 1 to the leveling keel 4 using self-tapping screws 8;

[0047] Step 3: Align the limiting head 22 on the fastener 2 with the opening 12 of the fixing part 1 and insert it, then rotate the rotating head 21 of the fastener 2 to make the limiting head 22 lock in the opening 12 and pull the insertion rod 23 tight.

[0048] Step 4: Install wall panels 3 on both sides of the insert 23 of fastener 2, so that the rotating head 21 of fastener 2 is locked in the joint of the two wall panels 3.

[0049] Step 5: Align the rotating head 21 of the fastener 2 with the decorative cover 6, and engage the second snap-fit ​​structure 61 on the decorative cover 6 with the first snap-fit ​​structure 24 on the rotating head 21 so that the decorative cover 6 is fastened to the rotating head 21.

[0050] As can be seen from the above installation steps, the wall panel 3 is installed on the keel 4 and the decorative cover 6 are installed using fastener 1 and fastener 2. The installation steps are simple and easy to operate, and the installation efficiency is high. In addition, fastener 2 can be installed by simply rotating to achieve double-head snap-fit ​​installation. It can be disassembled at any time later without damaging the wall panel 3.

[0051] In addition, combined Figure 1 Furthermore, a sound-absorbing pad 9 can be installed between the keel 4 and the wall panel 3 to prevent abnormal noises from occurring in the wall panel 3 later on, and also to provide sound insulation. This sound-absorbing pad 9 can be made of sound-absorbing cotton, sponge pads, or other materials; this embodiment does not limit the specific type of material.

[0052] The above are merely preferred embodiments of this disclosure and are not intended to limit this disclosure. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
