The lead screws 91 are threadedly connected to the left sides of the expansion plates 9. Servo motors 92 are installed on the right parts of the sides of the upper and lower guide plates 3 that are away from each other. The output shaft ends of the upper and lower servo motors 92 are respectively fixedly connected to the right ends of the upper and lower lead screws 91.

[0035] Please refer to Figures 5-7As shown in the figure, the auxiliary component includes a driving motor 10, a telescopic spline shaft 101, a curtain 102, a rotating seat 103, a clamping plate 104, a telescopic movable rod 105, a fixed guide plate 106 and a limiting component. A rotating seat 103 is rotatably connected to the middle of the inner bottom of the support frame 1. A spline groove is formed in the middle of the top of the rotating seat 103. A driving motor 10 is installed in the middle of the upper part of the electric lifting frame 2. The end of the output shaft of the driving motor 10 is rotatably connected to a telescopic spline shaft 101. The bottom end of the telescopic spline shaft 101 is located in the spline groove of the rotating seat 103. A curtain 102 is sleeved on the telescopic spline shaft 101. A clamping plate 104 is fixedly connected to the tail end of the curtain 102. Fixed guide plates 106 are symmetrically and fixedly connected to the front and back on the right side of the inner bottom of the support frame 1 and the right side of the inner top of the electric lifting frame 2. A telescopic movable rod 105 is slidably connected between the four fixed guide plates 106. The telescopic movable rod 105 contacts the clamping plate 104. When the telescopic movable rod 105 moves, the telescopic movable rod 105 can drive the clamping plate 104 to move, so that the curtain 102 is pulled out and unfolded. A limiting component is arranged on the guide plate 3. When the limiting component operates, the limiting component can limit the telescopic movable rod 105; the limiting component includes a limiting block 107 and a connecting spring 108. Limiting blocks 107 are embedded and slidably connected to the right inner parts of the front and back guide plates 3. The limiting blocks 107 are located on the right side of the telescopic movable rod 105. The limiting blocks 107 can limit the telescopic movable rod 105. The mutually approaching ends of the front and back limiting blocks 107 are symmetric inclined surfaces. Connecting springs 108 are connected between the inner sides of the front and back limiting blocks 107 and the inner sides of the front and back fixed guide plates 106 respectively.

[0036] First, move this device to the display position so that the electric lifting frame 2 and the support frame 1 are close to the wall. Start the electric lifting frame 2 to move up and down. Since the telescopic spline shaft 101 and the telescopic movable rod 105 can be telescoped, it will not affect the movement of the electric lifting frame 2. The electric lifting frame 2 drives the upper guide plate 3 to move up and down. When the upper guide plate 3 moves up and down to the required display height, turn off the electric lifting frame 2. Then, pull the clamping plate 104 to disengage from the telescopic movable rod 105, and then pull the telescopic movable rod 105 to move rightward to contact the limit block 107. The telescopic movable rod 105 squeezes the limit block 107, causing the front and rear limit blocks 107 to move outward, and the connecting spring 108 is compressed. When the telescopic movable rod 105 continues to move rightward and disengages from the limit block 107, due to the action of the connecting spring 108, the front and rear limit blocks 107 move inward to reset. Stop pulling the telescopic movable rod 105 to move rightward. At this time, the telescopic movable rod 105 does not affect the rightward swing of the telescopic spline shaft 101. Pull the lower part of the telescopic spline shaft 101 upward to disengage from the spline groove of the rotating seat 103, and then pull the telescopic spline shaft 101 to swing rightward to a suitable position. Then, remove the curtain 102 on the telescopic spline shaft 101, and put the curtain 102 of the required height on the telescopic spline shaft 101 according to the display height. In this way, the height of the scenery display can be adjusted according to the needs, thereby improving the adaptability. Pull the telescopic spline shaft 101 to swing leftward to reset to a vertical state, and release the lower part of the telescopic spline shaft 101. Due to the action of gravity, the telescopic spline shaft 101 extends and resets and inserts into the spline groove of the rotating seat 103. Then, push the telescopic movable rod 105 to move leftward and slide over the limit block 107 to reset. Pull the clamping plate 104 to clamp on the telescopic movable rod 105. Start the servo motor 92 to rotate forward to drive the lead screw 91 to rotate forward. The lead screw 91 rotates forward to drive the expansion plate 9 to move rightward. When the expansion plate 9 moves rightward to the maximum stroke, turn off the servo motor 92, and the lead screw 91 stops driving the expansion plate 9 to move rightward. Pull the telescopic movable rod 105 to move rightward and slide over the limit block 107. The telescopic movable rod 105 moves rightward to drive the curtain 102 to move rightward and unfold through the clamping plate 104. The telescopic movable rod 105 slides in the guide plate 3 and the expansion plate 9. When the telescopic movable rod 105 moves rightward to the maximum stroke in the expansion plate 9, stop pulling the telescopic movable rod 105 to move rightward, and the curtain 102 stops moving rightward. Then, start the projector 21 to project the color and pattern of the wall wallpaper onto the curtain 102 for scenery display. People can understand the appearance of the wall after decoration by viewing the color and pattern of the wall wallpaper on the curtain 102. When the scenery display is completed, turn off the projector 21. Start the drive motor 10 to rotate forward to drive the telescopic spline shaft 101 to rotate forward. The telescopic spline shaft 101 rotates forward to wind up and reset the curtain 102. The winding of the curtain 102 drives the telescopic movable rod 105 to move leftward to reset through the clamping plate 104, and the limit block 107 continues to limit the reset telescopic movable rod 105. Then, start the servo motor 92 to rotate in reverse to drive the lead screw 91 to rotate in reverse.The reverse rotation of the lead screw 91 drives the expansion plate 9 to move leftward to reset and retract. Then, it pulls the sliding sleeve 7 to move and disengage from the support plate 6. The return spring 71 is compressed. The sliding sleeve 7 moves upward to stop locking the swing rod 4. It pushes the upper and lower swing rods 4 to swing and retract in the direction away from each other. Release the sliding sleeve 7. Due to the action of the return spring 71, the sliding sleeve 7 moves back to its original position. At the same time, it pulls the support plate 6 to swing leftward. The leftward swing of the support plate 6 drives the upper and lower one-hole plates 8 to swing in the direction of approaching each other through the rotating shaft 5. The one-hole plate 8 drives the upper and lower sleeves 81 to move in the direction of approaching each other. The sleeve 81 drives the upper and lower wedge blocks 84 to move in the direction of approaching each other through the slide rod 82 and disengage from the through hole 83. The compression spring 85 is compressed. The wedge block 84 stops locking the guide plate 3. Then, the upper and lower guide plates 3 can be moved rightward and removed to complete the disassembly. Release the support plate 6. Due to the action of the compression spring 85, the upper and lower wedge blocks 84 move in the direction away from each other to reset. The wedge block 84 drives the upper and lower sleeves 81 to move in the direction away from each other to reset through the slide rod 82. The sleeve 81 drives the one-hole plate 8 to swing back to its original position. The one-hole plate 8 drives the support plate 6 to swing back to its original position through the rotating shaft 5. Then, the removed guide plate 3 can be carried to the next position together with the support frame 1 and the electric lifting frame 2 for scene setting and display. Due to the action of the limit block 107, it can prevent the telescopic movable rod 105 from falling off the fixed guide plate 106 and affecting the carrying. When scene setting and display are required, move the two guide plates 3 leftward and insert them into the support frame 1 and the electric lifting frame 2 respectively. The guide plate 3 moves leftward and contacts the wedge block 84. The guide plate 3 drives the upper and lower wedge blocks 84 to move in the direction of approaching each other. The compression spring 85 is compressed. When the through hole 83 corresponds to the wedge block 84 as the guide plate 3 continues to move leftward, due to the action of the compression spring 85, the upper and lower wedge blocks 84 move in the direction away from each other to reset and insert into the through hole 83. The wedge block 84 locks the guide plate 3 through the through hole 83. Then, pull the sliding sleeve 7 to move so that the return spring 71 is compressed. Subsequently, pull the upper and lower swing rods 4 to swing inward to the inner side of the support plate 6. Release the sliding sleeve 7. Due to the action of the return spring 71, the sliding sleeve 7 slides and contacts the support plate 6. The sliding sleeve 7 and the support plate 6 cooperate to lock the swing rod 4, thus completing the locking of the guide plate 3. In this way, rapid installation can be completed, and thus rapid scene setting and display can be carried out. When the scene setting and display are completed, the guide plate 3 can be quickly removed according to the above operations. In this way, it is convenient for disassembly and assembly and convenient for overall movement, thereby improving flexibility and the efficiency of scene setting and display.

[0037] Please refer to Figures 8-10As shown in the figure, the variable scenery display device for interior design further includes a support component installed on the support frame 1. The support component includes a frame body 11, a cylinder body 111, a support rod 112, a buffer spring 1121, a roller 1122 and a drive component. Frame bodies 11 are fixedly connected to the left sides of the front and rear outer side surfaces of the support frame 1. Cylinder bodies 111 are rotatably connected to the upper parts of the front and rear frame bodies 11. A support rod 112 is slidably connected to the inner side of the cylinder body 111. When the support rod 112 swings outwards and unfolds, the support rod 112 can support and limit the support frame 1. A buffer spring 1121 is connected between the top end of the support rod 112 and the inner top of the cylinder body 111. Rollers 1122 are rotatably connected to the bottom ends of the front and rear support rods 112. When the support rod 112 unfolds, the roller 1122 can guide the support rod 112 to reduce the friction with the ground. A drive component is arranged between the frame body 11 and the cylinder body 111. When the drive component operates, the drive component can drive the cylinder body 111 to swing; the drive component includes a connecting rod 113, a movable seat 114 and a drive screw 115. The movable seat 114 is slidably inserted through the lower parts of the front and rear frame bodies 11. Connecting rods 113 are rotatably connected to the left and right sides of the movable seat 114. The connecting rods 113 are located outside the frame body 11. The top ends of the left and right connecting rods 113 are rotatably connected to the middle part of the outer side surface of the cylinder body 111. The drive screw 115 is rotatably inserted through the top of the frame body 11. The drive screw 115 is threadedly connected to the middle part of the movable seat 114.

[0038] Initially, the buffer spring 1121 is in a compressed state. When the device moves to the position for setting display, turn the driving screw 115 clockwise. The clockwise rotation of the driving screw 115 drives the movable seat 114 to move upward. The upward movement of the movable seat 114 drives the front and rear cylinders 111 to swing outward through the connecting rod 113. The outward swing of the front and rear cylinders 111 drives the front and rear support rods 112 to swing outward. The outward swing of the front and rear support rods 112 drives the front and rear rollers 1122 to swing outward. Due to the action of the buffer spring 1121, the support rod 112 always presses on the roller 1122, making the roller 1122 always roll closely on the ground. The roller 1122 guides the outward swing of the support rod 112 to reduce the friction between the support rod 112 and the ground, making the outward swing of the support rod 112 smoother. When the movable seat 114 moves upward to the maximum stroke, stop turning the driving screw 115. The movable seat 114 stops moving upward, and the cylinder 111 stops driving the support rod 112 to swing outward. The support rod 112 and the cylinder 111 cooperate to support and limit the support frame 1, making the device more stable in use. When there is no need for setting display, turn the driving screw 115 counterclockwise to drive the movable seat 114 to move downward and reset. The reset of the movable seat 114 drives the front and rear cylinders 111 to swing inward and reset through the connecting rod 113. The cylinder 111 drives the front and rear support rods 112 to swing inward and reset. The inward swing of the support rod 112 drives the front and rear rollers 1122 to swing inward and retract and reset. At the same time, the buffer spring 1121 is compressed during the inward swing of the support rod 112, and then stop turning the driving screw 115. In this way, the phenomenon of shaking during the use of the device can be prevented from affecting the setting display, making the device more stable in use.

[0039] Please refer to Figure 11 As shown, the variable setting display device for interior design further includes a rubber pad 12. Rubber pads 12 are fixedly connected to the mutually remote sides of the upper and lower guide plates 3 and the mutually remote sides of the upper and lower extension plates 9. Rubber pads 12 are also fixedly connected to the outer sides of the support frame 1 and the electric lifting frame 2. The rubber pad 12 can protect the guide plate 3, the extension plate 9, the support frame 1 and the electric lifting frame 2.
