[0051] The following is in conjunction with the appendix Figure 1-22 The present invention will be described in further detail below.

[0052] like Figure 1 , 3As shown, a keel-free dry-hanging installation system for interior wall panel cladding includes an array of hangers 2 installed on the entire wall surface 1 and corner brackets 4 installed on the wall panel 3. The hangers 2 and corner brackets 4 are connected to form an array of wall panels 3. The hangers 2 include upper hangers 21, middle hangers 22, lower hangers 23, corner hangers 24 and side hangers 25 fixed to the top, middle, bottom, four corners and left and right sides of the wall surface 1. The corner brackets 4 include upper corner brackets 41 fixedly connected to the top two ends of the wall panel 3 and lower corner brackets 42 fixedly connected to the bottom two ends of the wall panel 3. The wall surface 1 is also provided with a hidden access door mechanism 5.

[0053] like Figure 1-5 As shown, the upper mounting part 21 includes an upper mounting plate 211, a left mounting part 215 and a right mounting part 216. The left mounting part 215 and the right mounting part 216 are symmetrically arranged on the left and right sides of the upper mounting plate 211. The left mounting part 215 includes a left mounting box 2151 with the opening facing forward, and the right mounting part 216 includes a right mounting box 2161 with the opening facing forward.

[0054] In this embodiment, the upper mounting plate 211 is vertically arranged, and the bottom of the upper mounting plate 211 is vertically connected to the bottom plate 212. The left and right ends of the upper mounting plate 211 are vertically fixed to the end plates 213. The two end plates 213 are also fixed to the bottom plate 212 respectively. There are partitions 214 between the two end plates 213, which are opposite to the corresponding end plates 213. The two partitions 214 are vertically fixed to the upper mounting plate 211 respectively. The bottom of the two partitions 214 is also fixed to the bottom plate 212 respectively. The end plate 213 on the left side of the upper mounting plate 211, the upper mounting plate 211, the partitions 214 and the bottom plate 212 form a left mounting box 2151. The end plate 213 on the right side of the upper mounting plate 211, the upper mounting plate 211, the partitions 214 and the bottom plate 212 form a right mounting box 2161.

[0055] The bottom of both the left mounting box 2151 and the right mounting box 2161 is provided with a sliding lifting plate 218. The bottom of both the left mounting box 2151 and the right mounting box 2161 is threadedly connected to a lifting screw 2121. The top of the lifting screw 2121 is rotatably connected to the corresponding lifting plate 218. The top of each lifting plate 218 is provided with a corresponding top plate 217. The two top plates 217 are respectively fixed to the upper mounting plate 211. By rotating the lifting screw 2121, the corresponding lifting plate 218 can be moved up and down.

[0056] like Figure 5As shown, in this embodiment, the end plates 213 of the left mounting box 2151 and the right mounting box 2161 and the corresponding partition plates 214 are provided with sliding grooves 219. The bottom front side of the sliding groove 219 is provided with a slot 2191, which communicates with the sliding groove 219. The width of the slot 2191 is the same as the width of the sliding groove 219. The lifting plate 218 is inserted into the slot 2191 and pushed into the sliding groove 219. Then, the lifting plate 218 is lifted by the lifting screw 2121 so that the lifting plate 218 is misaligned with the slot 2191, which can prevent the lifting plate 218 from detaching from the sliding groove 219.

[0057] like Figure 3-5 As shown, in one embodiment, in order to improve the firmness of the connection between the upper hanger 21 and the upper corner bracket 41, the top plate 217 of the left mounting box 2151 is threaded with a fastening bolt 2171, the threaded end of the fastening bolt 2171 facing the corresponding lifting plate 218, and the front end of the top plate 217 of the right mounting box 2161 is provided with a V-shaped spring piece 2172 that bends downward and backward.

[0058] like Figure 10 As shown, the upper corner bracket 41 is L-shaped. When the upper corner bracket 41 is attached to the upper hanging piece 21 at the top center of the wall 1, the hook of the upper corner bracket 41 is set horizontally. The hook of the upper corner bracket 41 is inserted between the top plate 217 and the corresponding lifting plate 218. By adjusting the lifting screw 2121, the height of the lifting plate 218 can be adjusted, thereby making fine adjustments to the height of the wall panel 3 connected to the upper corner bracket 41 to ensure the installation accuracy of the wall panel 3.

[0059] When the hook of the upper corner bracket 41 is inserted between the top plate 217 and the corresponding lifting plate 218 on the left mounting part 215, the hook of the upper corner bracket 41 can be clamped by rotating the fastening bolt 2171 to ensure the firmness of the wall panel 3 connected to it; after the hook of the upper corner bracket 41 is inserted between the top plate 217 and the corresponding lifting plate 218 of the right mounting box 2161, the V-shaped spring piece 2172 provided at the front end of the top plate 217 of the right mounting box 2161 has a downward clamping force on the hook of the upper corner bracket 41, ensuring the firmness of the wall panel 3 connected to it.

[0060] The upper bracket 21 adopts a symmetrical structure of left mounting part 215 and right mounting part 216. The top plate 217 of the left mounting box 2151 is threaded with fastening bolts 2171 to clamp the upper corner bracket 41 on the left side. The top plate 217 of the right mounting box 2161 is equipped with V-shaped spring pieces 2172 to stabilize and position the upper corner bracket 41 on the right side, so that the wall panel 3 can be installed sequentially from left to right. The wall panel 3 is easy to disassemble and maintain.

[0061] like Figure 6-8As shown, the intermediate mounting piece 22 includes an intermediate mounting plate 221. The left and right sides of the intermediate mounting plate 221 are provided with a pair of upper mounting parts 222 and a pair of lower mounting parts 223 from top to bottom. The upper mounting part 222 includes an upper mounting box 2221 with a forward opening. The upper mounting box 2221 is square. A spring 2222 is provided at the bottom of the upper mounting box 2221. A support plate 2223 is fixed above the spring 2222. A roller 2224 that can slide up and down is provided above the support plate 2223. The left and right side walls of the upper mounting box 2221 are provided with slides extending in the vertical direction. The two ends of the shaft of the roller 2224 are respectively embedded in the slides. The axis of the roller 2224 is parallel to the intermediate mounting plate 221. A clearance groove 2225 is provided on the outer side wall of the upper mounting box 2221. The low point of the clearance groove 2225 is lower than the top of the corresponding roller 2224.

[0062] The lower mounting part 223 includes an inverted L-shaped connecting plate 2231 and an L-shaped adjusting plate 2235. The connecting plate 2231 is fixedly connected to the intermediate mounting plate 221. The connecting plate 2231 includes a side plate 2232 and an upper plate 2233. The adjusting plate 2235 is located inside the corresponding connecting plate 2231. The top of the adjusting plate 2235 is provided with a hanging plate 2236. The top of the hanging plate 2236 is provided with a hanging groove with an upper opening. The axis of the hanging groove is parallel to the intermediate mounting plate 221. The cross-section of the hanging groove is inverted T-shaped. The hook at the bottom of the adjusting plate 2235 faces the corresponding side plate 2232. A receiving cavity 2237 is formed between the adjusting plate 2235 and the corresponding side plate 2232. An adjusting bolt 2234 is threadedly connected to the upper plate 2233. The threaded end of the adjusting bolt 2234 is engaged in the hanging groove. Since the axis of the hanging groove is parallel to the intermediate mounting plate 2231, the adjusting plate 2235 is fixedly connected to the middle mounting plate 2231. 21. Therefore, the adjusting plate 2235 can move horizontally closer to or further away from the corresponding side plate 2232 through the hanging groove and the adjusting bolt 2234 that is engaged with the hanging groove; rotating the adjusting bolt 2234 can also move the adjusting plate 2235 up or down through the hanging groove that is engaged with it. The adjusting plate 2235 and the corresponding side plate 2232 are fitted with locking bolts 2238; wherein, the locking bolt 2238 passes through the adjusting hole 7 provided on the adjusting plate 2235, the adjusting hole 7 is in the shape of a straight line and is set vertically; the setting of the adjusting hole 7 can avoid interference between the adjusting plate 2235 and the locking bolt 2238 during the up and down movement, and ensure that the lifting and lowering of the adjusting plate 2235 can be carried out smoothly; when the upper corner bracket 41 is engaged with the lower mounting part 223, the hook of the upper corner bracket 41 is set vertically and inserted into the receiving cavity 2237.

[0063] By adjusting the rotation of the bolt 2234, the adjusting plate 2235 can be moved up and down. The hook of the upper corner bracket 41, which cooperates with the lower mounting part 223, is set vertically. After the hook of the upper corner bracket 41 is inserted into the receiving cavity 2237, its lower end is located on the hook of the adjusting plate 2235. The up and down movement of the adjusting plate 2235 can drive the corresponding upper corner bracket 41 to move up and down, thereby achieving fine adjustment of the up and down position of the wall panel 3 connected to it, ensuring that the gap between adjacent wall panels 3 meets the specified requirements. By tightening the bolt 2238, the upper corner bracket 41 inserted into the receiving cavity 2237 can be clamped to ensure the firmness of the wall panel 3 hanging.

[0064] like Figure 11 As shown, the lower corner bracket 42 includes a fixing plate 421, a vertical plate 422, and a horizontal plate 423. The fixing plate 421 is fixedly connected to the wall panel 3. The vertical plate 422 is perpendicular to the fixing plate 421. The horizontal plate 423 is located at the lower end of the vertical plate 422 and is perpendicular to it. The horizontal plates 423 of the two lower corner brackets 42 on the same wall panel 3 extend in opposite directions. The horizontal plates 423 of the lower corner bracket 42 are inserted into the relief groove 2225 and abut against the corresponding roller 2224. That is, the wall panel 3 in the middle of the wall surface 1 is supported by the horizontal plates 423 on the lower corner bracket 42 inserted into the relief groove 2225 and abut against the corresponding roller 2224. Since the lowest point of the relief groove 2225 is lower than the top of the corresponding roller 2224, the elastic force of the spring 2222 below the roller 2224 can provide auxiliary support for the wall panel 3.

[0065] like Figure 10 As shown, the upper corner bracket 41 and the lower corner bracket 42 are respectively provided with waist-shaped mounting holes 8 horizontally. The upper corner bracket 41 and the lower corner bracket 42 are respectively fixed to the back of the wall panel 3 by back bolts passing through the waist-shaped mounting holes 8.

[0066] The middle bracket 22 includes a pair of upper mounting parts 222 and a pair of lower mounting parts 223 on the left and right sides. Four wall panels 3 can be connected through the four mounting parts respectively. The flatness and position of each wall panel 3 can be adjusted individually.

[0067] Figure 9 This is a schematic diagram of the connection structure of the upper and lower corner brackets of the wall panel connected to the middle of the wall surface.
