Description

Technical Field

[0001] This application relates to the field of wall panels, and more particularly to a seamless splicing decorative wall panel and its construction method. Background Technology

[0002] Decorative wall panels are an important material for interior decoration, with multiple functions such as beautifying the space, protecting the wall surface, improving practicality, and providing sound and heat insulation. When installing wall panels, they are first fixed to the wall surface with glue, and then the clips are fastened to the end of the wall panel. The clips are then fixed to the wall surface with bolts. The mechanical fastening provides immediate fixation and ensures that the wall panel remains stable before the glue is completely cured.

[0003] However, staff cannot directly observe the embedding of the wall panel end in the clip groove, which can easily cause the clip and the wall panel end to not fit tightly, forming gaps of varying widths, thereby reducing the decorative effect of the decorative wall panel. Summary of the Invention

[0004] To improve the decorative effect of decorative wall panels, this application provides a seamless splicing decorative wall panel and a construction method therefor.

[0005] Firstly, this application provides a seamless splicing decorative wall panel, which adopts the following technical solution: A seamless splicing decorative wall panel includes a panel body, clips, and a locking assembly. The clips have grooves on their surfaces for the ends of the panel body to be inserted into. The locking assembly includes a locking rod. The clips have locking holes on their surfaces for the locking rod to be inserted into. The locking holes are connected to the grooves. The panel body has locking cavities on the surface facing the locking holes for the locking rod to pass through. The locking cavities extend through both ends of the panel body in the thickness direction. When the end of the panel body is inserted into the groove, the locking cavities are connected to the locking holes. One end of the locking rod passes through the locking holes and is inserted into the locking cavities, while the other end of the locking rod is flush with the clip surface.

[0006] By adopting the above technical solution, when the panel is pre-fixed to the wall surface with glue, the bottom of the buckle abuts against the ground and drives the buckle end face with the slot close to the panel. The end of the panel is embedded in the slot, and the locking cavity is connected to the locking hole. The staff can judge the embedding of the end of the panel in the slot by the connection between the locking hole and the locking cavity. At the same time, the end of the locking rod passes through the locking hole and is embedded in the locking cavity, and the other end of the locking rod is flush with the buckle surface, so that the end of the panel is not easy to fall out of the slot. This further improves the connection stability between the panel and the buckle, ensures that the buckle and the end of the panel fit tightly and does not easily form gaps, and completes the seamless splicing of the panel, thereby improving the decorative effect of the decorative wall panel.

[0007] Optionally, the plate includes a fixing part, a fitting part, and a clamping part. One end of the fixing part is connected to the end face of the fitting part, and the other end of the fixing part is connected to the end face of the clamping part. One end of the fixing part has a fitting groove for the fitting part to be inserted into, and the other end of the fixing part has a clamping groove for the clamping part to be inserted into. The clamping groove and the fitting part are located on the same side of the fixing part. When the fitting part is inserted into the fitting groove and the clamping part is inserted into the clamping groove, the end faces of two adjacent fixing parts are flush. Both ends of the fixing part have mounting cavities for accommodating the buckle. One of the mounting cavities is connected to the clamping groove, and the end of the clamping part away from the fixing part can be inserted into the buckle groove.

[0008] By adopting the above technical solution, when one of the panels is fixed to the wall surface with glue, the buckle is embedded in the installation cavity that is connected to the clamping groove, and the end of the clamping part away from the fixing part is embedded in the buckle groove. The locking hole is connected to the locking cavity. One end of the locking rod passes through the locking hole and is embedded in the locking cavity. The other end of the locking rod is flush with the buckle surface, driving the other panel to approach the buckle. The installation cavities on the two adjacent panels are connected to accommodate the buckle. At the same time, the clamping part on the panel is embedded in the clamping groove of the adjacent panel, and the fitting part on the adjacent panel is embedded in the fitting groove on the panel. The inner wall of the fitting groove is pressed against the surface of the fitting part to form a limit. The end faces of the two fixing parts are flush, ensuring that the ends of the two adjacent panels fit tightly and are not prone to forming gaps, thereby further improving the decorative effect of the decorative wall panel.

[0009] Optionally, the buckle includes an mounting part, a connecting part, and a fastening part. The mounting part has multiple threaded holes for bolts to pass through. One end of the connecting part is connected to the surface of the mounting part, and the other end of the connecting part is connected to the surface of the fastening part. The slot is located between the fastening part, the connecting part, and the mounting part. The mounting cavity is for the mounting part to be embedded. The end face of the abutting part away from the fixing part has a positioning cavity for accommodating the fastening part and the connecting part. The positioning cavity is connected to the locking cavity. When the abutting part is embedded in the slot, the fastening part and the connecting part are embedded in the positioning cavity. The surface of the fastening part is flush with the surface of the abutting part, and the inner wall of the abutting groove and the inner wall of the positioning cavity clamp the outer peripheral surface of the connecting part to form a limit.

[0010] By adopting the above technical solution, when the clamping part is embedded in the slot, the fastening part and the connecting part are embedded in the positioning cavity, and the surface of the fastening part is flush with the surface of the clamping part. The bolt end is threaded through a threaded hole and screwed on to fix it to the wall surface, thereby achieving the fixation of the buckle on the wall. At the same time, it drives the adjacent plate to approach the buckle, and the clamping part on the plate is embedded in the clamping groove of the adjacent plate. The fitting part on the adjacent plate is embedded in the fitting groove on the plate, and the inner wall of the clamping groove and the inner wall of the positioning cavity clamp the outer peripheral surface of the connecting part to form a limit, further improving the tightness of the fit between the two adjacent plates.

[0011] Optionally, the locking assembly further includes a locking ring bladder, the outer ring wall of which is coaxially connected to the inner wall of the locking hole, and the inner ring wall of which can abut against the outer circumferential surface of the locking rod to form a limit.

[0012] By adopting the above technical solution, when the end of the locking rod passes through the locking hole and is embedded in the locking cavity, the outer ring wall of the locking ring bladder abuts against the inner wall of the locking hole, and the inner ring wall of the locking ring bladder abuts against the outer circumferential surface of the locking rod to form a limit, so that the locking rod is not easy to deviate and squeeze the inner wall of the locking groove in the locking hole, thereby ensuring the flatness of the plate surface.

[0013] Optionally, the locking assembly further includes a locking piston and an elastic element. The surface of the engaging portion facing the locking groove has an air passage for the locking piston to slide. The air passage connects to the inner cavity of the locking ring bladder. One end of the elastic element in the elastic direction is connected to the surface of the locking piston, and the other end of the elastic element in the elastic direction is connected to the inner wall of the air passage. The elastic element has the elastic force to drive the locking piston to slide away from the locking ring bladder, and the end of the locking piston tends to protrude from the surface of the engaging portion.

[0014] By adopting the above technical solution, the elastic element drives the locking piston to slide away from the locking ring bladder, and the end of the locking piston protrudes from the surface of the fastening part. At the same time, the inner cavity of the locking ring bladder is connected to the inflation channel, which brings the air in the locking ring bladder into the inflation channel. The inner ring wall of the locking ring bladder is depressurized and contracts. The end of the locking rod passes through the locking hole and is embedded in the locking cavity, reducing the wear between the locking rod and the locking ring bladder. When two adjacent plates are attached, the fitting part on one plate is embedded in the fitting groove of the adjacent plate, and the abutting part on the adjacent plate is embedded in the abutting groove. The end faces of the two adjacent fixing parts are flush. At the same time, the inner wall of the abutting groove abuts against the end face of the locking piston and pushes the locking piston to slide closer to the locking ring bladder. This brings the air in the inflation channel into the inner cavity of the locking ring bladder. The inner ring wall of the locking ring bladder is pressurized and expands, and abuts against the outer circumference of the locking rod to form a limit, thereby further improving the tightness of the fit between the plate and the buckle.

[0015] Optionally, the locking assembly further includes a locking strip and a connecting strip. The surface of the fastening part has a slide rail for the locking strip to slide, and the slide rail communicates with the locking hole. The surface of the locking rod has a locking groove for the end of the locking strip to be inserted. The sliding direction of the locking strip is parallel to the sliding direction of the locking piston. One end of the connecting strip is connected to the end of the locking strip away from the locking hole, and the other end of the connecting strip is connected to the end of the locking piston away from the locking ring. The surface of the fastening part has a connecting cavity for accommodating the connecting strip, and the connecting cavity communicates with the inflation channel and the slide rail.

[0016] By adopting the above technical solution, when the locking rod end passes through the locking hole and is embedded in the locking cavity, rotating the locking rod drives the locking groove to connect with the slide. When the two plates are spliced ​​and fixed, the inner wall of the locking groove abuts against the surface of the connecting strip and pushes the connecting strip into the connecting cavity. The surface of the connecting strip is flush with the surface of the fastening part. At the same time, the locking strip is pushed to slide along the inner wall of the slide towards the locking groove. The end of the locking strip is embedded in the locking groove, and the end face of the locking strip abuts against the inner wall of the locking groove and limits the sliding of the locking rod, further improving the tightness of the engagement between the plate and the buckle.

[0017] Optionally, the locking assembly further includes a fastening block and an elastic element two. The surface of the fitting part facing the fitting groove is provided with a sliding groove for the fastening block to slide. The inner wall of the fitting groove is provided with a positioning groove for the end of the fastening block to be embedded. One end of the elastic element two in the elastic direction is connected to the surface of the fastening block, and the other end of the elastic element two in the elastic direction is connected to the inner wall of the sliding groove. The elastic element two has the tendency to elastically drive the end of the fastening block to be embedded in the positioning groove.

[0018] By adopting the above technical solution, when the fitting part is embedded in the fitting groove, the positioning groove connects to the sliding groove, and the elastic force of the elastic element drives the fastening block to slide towards the positioning groove. The end of the fastening block is embedded in the positioning groove, and the outer peripheral surface of the fastening block abuts against the inner wall of the positioning groove to form a limit, so that the two adjacent plates are not prone to displacement and gaps when they are spliced, thus improving the stability of seamless splicing between adjacent plates. At the same time, the staff can judge the splicing status between the two plates based on the sound of the fastening block being embedded in the positioning groove, further improving the splicing accuracy of adjacent plates.

[0019] Optionally, the end of the fastening block protruding from the fitting part is provided with a guide surface. The guide surface is in the shape of a circular arc protrusion. The guide surface can abut against the inner wall of the fitting groove and guide the end of the fastening block to be embedded in the positioning groove.

[0020] By adopting the above technical solution, when two plates are spliced, the fitting part is embedded in the fitting groove, the guide surface abuts against the inner wall of the fitting groove and guides the end of the fastening block to be embedded in the positioning groove, reducing the wear between the fastening block and the plate, thereby improving the stability of the fastening block embedded in the positioning groove.

[0021] Optionally, the locking assembly further includes multiple elastic arc blocks, which are spaced apart and connected to the inner wall of the locking cavity. The multiple elastic arc blocks are spliced ​​together to form a circular plate and cover the locking cavity. When the end of the locking rod passes through the locking hole and is embedded in the locking cavity, the outer circumferential surface of the locking rod and the inner wall of the locking cavity clamp the two sides of the elastic arc blocks to form a limit.

[0022] By adopting the above technical solution, when the locking rod end passes through the locking hole and is embedded in the locking cavity, the locking rod surface compresses the surface deformation of the elastic arc block, and the outer circumferential surface of the locking rod and the inner wall of the locking cavity clamp the two sides of the elastic arc block to form a limit, making it difficult for the locking rod to deviate in the locking cavity, thereby improving the limiting stability of the locking rod in the locking cavity.

[0023] Secondly, this application provides a seamless splicing decorative wall panel construction method, which adopts the following technical solution: The construction method for seamless splicing decorative wall panels includes the following steps: The clips are used for fixing, with the bottom of the clips abutting against the positioning point on the wall. Bolts are passed through the clips and tightened with threads to fix the clips to the wall surface. The panels are fixed in two ways: one panel is fixed to the wall with glue at the bottom, and the end of the panel is embedded in a slot. The inner wall of the slot is pressed against the end of the panel, and the pressing hole is connected to the pressing cavity. One end of the pressing rod passes through the pressing hole and is embedded in the pressing cavity. The other end of the pressing rod is flush with the buckle surface. The bottom of the other panel is fixed to the wall with glue, and the two panels are spliced ​​and fixed.

[0024] By adopting the above technical solution, when one end of the panel is embedded in the slot, the clamping hole connects to the clamping cavity, one end of the clamping rod passes through the clamping hole and is embedded in the clamping cavity, and the other end of the clamping rod is flush with the buckle surface, making it difficult for the end of the panel to fall out of the slot, thereby further improving the connection stability between the panel and the buckle, ensuring that the buckle and the end of the panel fit tightly and are not prone to forming gaps, completing the seamless splicing of the panels, thereby improving the decorative effect of the decorative wall panel.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The locking rod design prevents the panel ends from easily detaching from the slot, thereby further improving the connection stability between the panel and the buckle, ensuring a tight fit between the buckle and the panel ends, preventing gaps, and achieving seamless splicing of the panels, thus improving the decorative effect of the decorative wall panels. 2. The setting of fixing part, fitting part and abutting part, the inner wall of the fitting groove abuts against the surface of the fitting part to form a limit, and the end faces of the two fixing parts are flush, ensuring that the ends of the two adjacent panels fit tightly and are not easy to form gaps, thereby further improving the decorative effect of the decorative wall panel; 3. The installation part, connecting part and fastening part are provided such that the fitting part on the adjacent plate is embedded in the fitting groove on the plate, and abuts against the inner wall of the groove and the inner wall of the positioning cavity to clamp the outer peripheral surface of the connecting part to form a limit, thereby further improving the tightness of the fit between the two adjacent plates.

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0031] This application discloses a seamless splicing decorative wall panel. (Refer to...) Figure 1 and Figure 2 The seamless splicing decorative wall panel includes a panel 1, a clip 2, and a locking assembly 3. The clip 2 is fixed to the wall surface with bolts, and the bottom of the panel 1 is glued to the wall surface. The end face of the clip 2 has a groove 21 for the end of the panel 1 to be inserted. The locking assembly 3 is installed between the clip 2 and the panel 1. The locking assembly 3 can limit the end of the panel 1 to be within the groove 21, making it difficult for the end of the panel 1 to fall out of the groove 21, thereby further improving the connection stability between the panel 1 and the clip 2, ensuring that the clip 2 and the end of the panel 1 fit tightly and are not prone to forming gaps, thus completing the seamless splicing of the panel 1 and improving the decorative effect of the decorative wall panel.

[0032] Reference Figure 2 and Figure 3The panel 1 includes a fixing part 11, a fitting part 12, and a clamping part 13. One end of the fixing part 11 is integrally formed and fixed to the end face of the fitting part 12, and the other end of the fixing part 11 is integrally formed and fixed to the end face of the clamping part 13. One end of the fixing part 11 has a fitting groove 111 for the fitting part 12 to be inserted into, and the other end of the fixing part 11 has a clamping groove 112 for the clamping part 13 to be inserted into. The clamping groove 112 and the fitting part 12 are located on the same side of the fixing part 11. When two panels 1 are close to each other and spliced, the fitting part 12 on one panel 1 is inserted into the fitting groove 111 of the adjacent panel 1, and the clamping part 13 on the adjacent panel 1 is inserted into the clamping groove 112. The end faces of the two fixing parts 11 are clamped together, and the panel surfaces of the two adjacent fixing parts 11 are flush, thus achieving seamless splicing between the two panels 1 and improving the splicing quality of the decorative wall panel.

[0033] Reference Figure 2 and Figure 3 Both ends of the fixing part 11 are provided with mounting cavities 113 to accommodate the buckle 2. One of the mounting cavities 113 is connected to the abutment groove 112, and the end of the abutment part 13 away from the fixing part 11 can be embedded in the slot 21. When the two plates 1 are spliced ​​together, the mounting cavities 113 on the two adjacent fixing parts 11 are connected, the buckle 2 is located in the mounting cavity 113, and at the same time, the end of the abutment part 13 in the abutment groove 112 connected to the mounting cavity 113 is embedded in the slot 21. The inner wall of the slot 21 abuts against the end face of the abutment part 13 to form a limit, thereby realizing the snap-fit ​​fixation between the buckle 2 and the plate 1.

[0034] Reference Figure 2 and Figure 3 The number of buckles 2 can be one, two or more. In this embodiment, the number of buckles 2 is multiple. The arrangement direction of buckles 2 is parallel to the length direction of mounting cavity 113. Buckles 2 include mounting part 22, connecting part 23 and fastening part 24. The surface of mounting part 22 is provided with multiple threaded holes 221 for bolts to pass through. The threaded holes 221 penetrate both sides of the thickness direction of mounting part 22 along their own axis. The end of the bolt can pass through the threaded hole 221 and be threaded and tightened to fix it to the wall, thereby fixing the mounting part 22 to the wall. One end of connecting part 23 is integrally formed and fixed to the surface of mounting part 22. The other end of connecting part 23 is integrally formed and fixed to the end face of fastening part 24. The slot 21 is located between connecting part 23, fastening part 24 and mounting part 22. Mounting cavity 113 is for mounting part 22 to be embedded. The end face of the abutting part 13 away from the fixing part 11 is provided with a positioning cavity 132 to accommodate fastening part 24 and connecting part 23.

[0035] Reference Figure 2 and Figure 3When the clamping part 13 is inserted into the slot 21, one end of the mounting part 22 is inserted into one of the mounting cavities 113. The inner wall of the mounting cavity 113 abuts against the surface of the mounting part 22 to form a limit. At the same time, the fastening part 24 and the connecting part 23 are inserted into the positioning cavity 132. The inner wall of the positioning cavity 132 abuts against the surface of the fastening part 24 and the surface of the connecting part 23. The surfaces of the fastening part 24 and the connecting part 23 are flush with the surface of the clamping part 13, thereby achieving the clamping and fixing of the buckle 2 with one of the plates. When another plate is clamped and fixed with the plate, the fitting part 12 on the other plate is inserted into the fitting groove 111 of the plate, and the clamping part 13 on the plate is inserted into the clamping groove 112. The inner wall of the positioning cavity 132 and the inner wall of the clamping groove 112 clamp the outer peripheral surface of the connecting part 23 to form a limit, thereby achieving seamless splicing of two adjacent plates and improving the splicing efficiency of the decorative wall panel.

[0036] Reference Figure 2 and Figure 3 The locking assembly 3 includes a locking rod 31, a locking ring 32, a locking piston 33, an elastic element 34, a locking bar 35, a connecting bar 36, a fastening block 37, an elastic element 38, and multiple elastic arc blocks 39. The fastening part 24 has a locking hole 241 on its surface facing the abutment groove 112 for the locking rod 31 to pass through. The locking hole 241 extends along its own axis through both sides of the fastening part 24 in the thickness direction. The abutment part 13 has a locking cavity 131 on its plate surface facing the locking hole 241 for the locking rod 31 to pass through. The locking cavity 131 extends along its own axis through both sides of the abutment part 13 in the thickness direction. The mounting part 22 faces the locking hole 241. The surface of 41 is provided with a fixing groove 222 for the end of the locking rod 31 to be inserted. When the abutting part 13 is inserted into the slot 21 and the locking cavity 131 is connected to the locking hole 241 and the fixing groove 222, one end of the locking rod 31 passes through the locking hole 241 and the locking cavity 131 and is inserted into the fixing groove 222. The other end of the locking rod 31 is flush with the surface of the fastening part 24, so that the abutting part 13 is not easy to disengage from the slot 21, thereby further improving the connection stability between the panel 1 and the buckle 2, ensuring that the buckle 2 and the end of the panel 1 are tightly fitted and not easy to form gaps, completing the seamless splicing of the panel 1, thereby improving the decorative effect of the decorative wall panel.

[0037] Reference Figure 2 and Figure 3The locking ring bladder 32, locking piston 33, and elastic arc block 39 can be made of rubber or silicone. In this embodiment, the locking ring bladder 32, locking piston 33, and elastic arc block 39 are all made of rubber, which has a certain deformation capability. Multiple elastic arc blocks 39 are connected at intervals to the inner wall of the locking cavity 131. Multiple elastic arc blocks 39 are spliced ​​together to form a circular plate and cover the locking cavity 131. When the end of the locking rod 31 passes through the locking cavity 131 and is embedded in the fixing groove 222, the elastic arc block 39 is deformed by the rod surface of the locking rod 31. The rod surface of the locking rod 31 and the inner wall of the locking cavity 131 clamp the two sides of the elastic arc block 39 to form a limit, so that the locking rod 31 is not easy to deviate in the locking cavity 131, thereby improving the clamping force between the locking rod 31 and the inner wall of the locking cavity 131.

[0038] Reference Figure 2 and Figure 3 The outer ring wall of the locking ring bladder 32 is coaxially connected to the inner wall of the locking hole 241. The inner ring wall of the locking ring bladder 32 can abut against the outer circumferential surface of the locking rod 31 to form a limit. The surface of the fastening part 24 facing the locking groove 311 is provided with an air passage 242 for the sliding of the locking piston 33. The sliding direction of the locking piston 33 is perpendicular to the axis of the locking hole 241. The air passage 242 is connected to the inner cavity of the locking ring bladder 32. The first elastic element 34 and the second elastic element 38 can be compression springs or tension springs. In the embodiment of this application, the first elastic element 34 and the second elastic element 38 are compression springs with a certain deformation capability. One end of the first elastic element 34 in the elastic direction is connected to the inner wall of the air passage 242, and the other end of the first elastic element 34 in the elastic direction is connected to the end face of the locking piston 33. The first elastic element 34 has the elastic force to drive the locking piston 33 to slide away from the locking ring bladder 32, and the end of the locking piston 33 protrudes from the surface of the fastening part 24.

[0039] Reference Figure 2 and Figure 3 The fastening part 24 has a slide 243 on the end face of the locking groove 311 for the locking strip 35 to slide. The sliding direction of the locking strip 35 is parallel to the sliding direction of the locking piston 33. The slide 243 is connected to the locking hole 241. The locking rod 31 has a locking groove 311 on the end face of the slide 243 for the end of the locking strip 35 to be inserted. One end of the connecting strip 36 is integrally formed and fixed to the end face of the locking strip 35 away from the locking hole 241. The other end of the connecting strip 36 is integrally formed and fixed to the end face of the locking piston 33 away from the locking ring 32. The connecting strip 36 protrudes from the surface of the fastening part 24, and the fastening part 24 has a connecting cavity on the end face of the connecting strip 36 to accommodate the connecting strip 36. The connecting cavity is connected to the inflation channel 242 and the slide 243.

[0040] Reference Figure 2 and Figure 3The elastic element 34 forces the locking piston 33 to slide away from the locking ring bladder 32 along the inflation channel 242. Air from the locking ring bladder 32 enters the inflation channel 242, causing the inner wall of the locking ring bladder 32 to contract due to pressure reduction. One end of the locking rod 31 passes through the locking hole 241 and the locking cavity 131 and is embedded in the fixing groove 222. The other end of the locking rod 31 is flush with the surface of the fastening part 24. At the same time, the locking groove 311 connects to the slide 243, causing another plate 1 to be snapped and fixed on the plate 1. The abutting part 13 on the plate 1 is embedded in the abutting groove 112 of the adjacent plate 1. The inner wall of the abutting groove 112 abuts against the surface of the connecting strip 36 and pushes the connecting strip 36. The locking piston 33 is inserted into the connecting cavity, and the inner wall of the connecting cavity abuts against the surface of the connecting strip 36 to form a limit. The locking piston 33 is pushed to slide along the inner wall of the air passage 242 toward the direction of the locking ring bladder 32. The air in the air passage 242 enters the inner cavity of the locking ring bladder 32. The inner ring wall of the locking ring bladder 32 is pressurized and expands, and abuts against the outer circumference of the locking rod 31 to form a limit. At the same time, the locking strip 35 is pushed along the inner wall of the slide 243 toward the direction of the locking groove 311. The end of the locking strip 35 is inserted into the locking groove 311. The inner wall of the locking groove 311 abuts against the end face of the locking strip 35 to form a limit, so that the locking rod 31 is not easily squeezed against the inner wall of the locking groove 112, thereby ensuring the flatness of the plate surface of the plate 1.

[0041] Reference Figure 2 and Figure 3 The fitting part 12 has a sliding groove 121 on the surface facing the fitting groove 111 for the fastening block 37 to slide. The sliding direction of the fastening block 37 is parallel to the axis of the locking hole 241. The fitting groove 111 has a positioning groove 114 on the inner wall facing the sliding groove 121 for the end of the fastening block 37 to be inserted. One end of the elastic member 38 in the elastic direction is connected to the surface of the fastening block 37, and the other end of the elastic member 38 in the elastic direction is connected to the inner wall of the sliding groove 121. The elastic member 38 has the elasticity to drive the fastening block 37 to slide towards the positioning groove 114, and the end of the fastening block 37 tends to be inserted into the positioning groove 114.

[0042] Reference Figure 2 and Figure 3 The end face of the fastening block 37 protruding from the fitting part 12 is provided with a guide surface 371. The guide surface 371 is in the shape of a rounded protrusion. When the fitting part 12 is inserted into the fitting groove 111, the guide surface 371 abuts against the inner wall of the fitting groove 111 and guides the end of the fastening block 37 to be inserted into the positioning groove 114. The inner wall of the positioning groove 114 abuts against the end face of the fastening block 37 to form a limit. The operator can judge the engagement status of the fitting part 12 in the fitting groove 111 by the sound of the fastening block 37 being inserted into the positioning groove 114, which further improves the splicing accuracy between two adjacent plates 1, makes it less likely to leave gaps between two adjacent plates 1, and completes the seamless splicing of adjacent plates 1.

[0043] The implementation principle of a seamless splicing decorative wall panel in this application embodiment is as follows: When multiple panels 1 are seamlessly spliced, multiple clips 2 are abutted against the wall surface according to the installation points. The bolt ends are threaded through threaded holes 221 and screwed tightly onto the wall surface, thereby fixing the multiple clips 2 to the wall surface. The surface of the fixing part 11 of one of the panels 1 is pre-fixed to the wall surface with glue. One end of the mounting part 22 is embedded in one of the mounting cavities 113. The inner wall of the mounting cavity 113 abuts against the surface of the mounting part 22 to form a limit. At the same time, the fastening part 2 4. The connecting part 23 is embedded in the positioning cavity 132. The inner wall of the positioning cavity 132 abuts against the surface of the fastening part 24 and the surface of the connecting part 23, and the surfaces of the fastening part 24 and the connecting part 23 are flush with the surface of the abutting part 13. One end of the locking rod 31 passes through the locking hole 241 and the locking cavity 131 and is embedded in the fixing groove 222. The other end of the locking rod 31 is flush with the surface of the fastening part 24. At the same time, the locking groove 311 connects to the slide 243, driving another plate 1 to be snapped and fixed on the plate 1. The abutting part 13 on the plate 1 is embedded. Within the clamping groove 112 of the adjacent plate 1, the inner wall of the clamping groove 112 abuts against the surface of the connecting strip 36 and pushes the connecting strip 36 into the connecting cavity. The inner wall of the connecting cavity abuts against the surface of the connecting strip 36 to form a limit. This pushes the locking piston 33 to slide along the inner wall of the air passage 242 toward the direction close to the locking ring bladder 32. Air in the air passage 242 enters the inner cavity of the locking ring bladder 32. The inner ring wall of the locking ring bladder 32 is pressurized and expands, abutting against the outer circumference of the locking rod 31 to form a limit. At the same time, it pushes the locking strip 35 along the inner wall of the slide 243 toward the direction close to the locking ring bladder 32. The locking groove 311 slides in a direction, and the end of the locking strip 35 is embedded in the locking groove 311. The inner wall of the locking groove 311 abuts against the end face of the locking strip 35 to form a limit, so that the locking rod 31 is not easy to squeeze the inner wall of the abutment groove 112, thereby ensuring the flatness of the panel 1. The abutment part 13 is not easy to disengage from the slot 21, thereby further improving the connection stability between the panel 1 and the buckle 2, ensuring that the buckle 2 and the end of the panel 1 fit tightly and are not easy to form gaps, completing the seamless splicing of the panel 1, thereby improving the decorative effect of the decorative wall panel.

[0044] This application also discloses a construction method for seamless splicing decorative wall panels, which uses seamless splicing decorative wall panels and includes the following steps: The buckle 2 is fixed, with the bottom of the buckle 2 abutting against the positioning point on the wall. The bolt passes through the buckle 2 and is tightened by thread to fix it to the wall surface. The board 1 is fixed, with one board 1 fixed to the wall at the bottom by glue, and the end of the board 1 is embedded in the slot 21. The inner wall of the slot 21 is pressed against the end of the board 1, and the pressing hole is connected to the pressing cavity. One end of the pressing rod passes through the pressing hole and is embedded in the pressing cavity. The other end of the pressing rod is flush with the surface of the buckle 2. The bottom of the other board 1 is fixed to the wall by glue, and the two boards 1 are spliced ​​and fixed.

[0045] The implementation principle of the seamless splicing decorative wall panel construction method in this application embodiment is as follows: when one end of the panel 1 is embedded in the slot 21, the clamping hole connects to the clamping cavity, one end of the clamping rod passes through the clamping hole and is embedded in the clamping cavity, and the other end of the clamping rod is flush with the surface of the buckle 2, so that the end of the panel 1 is not easy to detach from the slot 21, thereby further improving the connection stability between the panel 1 and the buckle 2, ensuring that the buckle 2 and the end of the panel 1 fit tightly and are not easy to form gaps, thus completing the seamless splicing of the panel 1, thereby improving the decorative effect of the decorative wall panel.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
