[0033] See also Figure 5-Figure 7As shown, the auxiliary components include a driving motor 10, a telescopic spline shaft 101, a curtain 102, a rotating seat 103, a card plate 104, a telescopic movable rod 105, a fixed guide plate 106 and a limiting component. The rotating seat 103 is rotatably connected to the middle of the bottom of the support frame 1, and a spline groove is opened in the middle of the top of the rotating seat 103. The driving motor 10 is installed in the middle of the upper part of the electric lifting frame 2. The output shaft end of the driving motor 10 is rotatably connected to the telescopic spline shaft 101. The bottom end of the telescopic spline shaft 101 is located in the spline groove of the rotating seat 103. The curtain 102 is sleeved on the telescopic spline shaft 101, and the card plate 104 is fixed to the tail end of the curtain 102. The fixed guide plate 106 is symmetrically fixed to the right side of the bottom of the support frame 1 and the right side of the top of the electric lifting frame 2. The telescopic movable rod 10 is slidably connected between the four fixed guide plates 106. 5. The telescopic movable rod 105 is in contact with the card plate 104. When the telescopic movable rod 105 moves, the telescopic movable rod 105 can drive the card plate 104 to move, so that the curtain 102 is pulled out and unfolded. A limit assembly is set on the guide plate 3. When the limit assembly is in operation, the limit assembly can limit the telescopic movable rod 105; the limit assembly includes a limit block 107 and a connecting spring 108. The right inner parts of the front and rear guide plates 3 are both embedded with a sliding connection limit block 107. The limit block 107 is located on the right side of the telescopic movable rod 105. The limit block 107 can limit the telescopic movable rod 105. The ends of the front and rear limit blocks 107 that are close to each other are symmetrical inclined surfaces. The inner sides of the front and rear limit blocks 107 are respectively connected to the inner sides of the front and rear fixed guide plates 106 with connecting springs 108.

[0034] First, move the device to the display position so that the electric lifting frame 2 and the support frame 1 are close to the wall, and start the electric lifting frame 2 to move up and down. Since the telescopic spline shaft 101 and the telescopic movable rod 105 are retractable, they 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, the electric lifting frame 2 is closed, and the clamping plate 104 can be pulled to disengage the telescopic movable rod 105, and then the telescopic movable rod 105 is pulled to move to the right and contact the limit block 107. The telescopic movable rod 105 squeezes the limit block 107, so that the limit blocks 107 on the front and rear sides move outward, and the connecting spring 108 is compressed, and the telescopic movable rod 105 continues to move to the right and disengages from the limit block 107 When in contact, due to the action of the connecting spring 108, the limit blocks 107 on the front and rear sides move inwards and reset, and the pulling of the telescopic movable rod 105 to the right stops. The telescopic movable rod 105 does not affect the rightward swing of the telescopic spline shaft 101 at this time. The lower part of the telescopic spline shaft 101 is pulled upward to disengage the spline groove of the rotating seat 103, and then the telescopic spline shaft 101 is pulled to the right to swing to a suitable position, and then the curtain 102 on the telescopic spline shaft 101 is removed, and the curtain 102 of the required height is put on the telescopic spline shaft 101 according to the height of the display. In this way, the height of the scenery display can be adjusted according to needs, thereby improving adaptability, and the telescopic spline shaft 101 is pulled to swing to the left to reset to a vertical state, and the lower part of the telescopic spline shaft 101 is released. Due to gravity, The telescopic spline shaft 101 is extended and reset and inserted into the spline groove of the rotating seat 103, and then the telescopic movable rod 105 is pushed to move to the left and slide over the limit block 107 to reset, and the card plate 104 is pulled to be stuck on the telescopic movable rod 105, and the servo motor 92 is started to rotate forward to drive the screw rod 91 to rotate forward, and the screw rod 91 rotates forward to drive the expansion plate 9 to move to the right. When the expansion plate 9 moves to the right to the maximum stroke, the servo motor 92 is turned off, and the screw rod 91 stops driving the expansion plate 9 to move to the right, and the telescopic movable rod 105 is pulled to move to the right and slide over the limit block 107. The telescopic movable rod 105 moves to the right and drives the curtain 102 to move to the right and unfold through the card 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 to the right to the expansion plate 9, When the display board 9 reaches the maximum stroke, stop pulling the telescopic movable rod 105 to move right, the screen 102 stops moving right, and the projector 21 can be started to project the color and pattern of the wall wallpaper onto the screen 102 for scenery display. People can understand the appearance of the wall after decoration by checking the color and pattern of the wall wallpaper on the screen 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, and the telescopic spline shaft 101 rotates forward to rewind the screen 102 and reset it. The rewinding of the screen 102 drives the telescopic movable rod 105 to move left and reset through the card plate 104, and the limit block 107 continues to limit the reset telescopic movable rod 105, and then start the servo motor 92 to reverse and drive the screw rod 91 to reverse.The screw rod 91 reverses and drives the expansion plate 9 to move to the left and reset and retract, and then pulls the sliding sleeve 7 to move and disengage from the support plate 6. The reset spring 71 is compressed, and the sliding sleeve 7 moves upward to stop locking the swing rod 4, pushing the upper and lower swing rods 4 to swing away from each other and retract, and releasing the sliding sleeve 7. Due to the action of the reset spring 71, the sliding sleeve 7 moves and resets, and at the same time pulls the support plate 6 to swing to the left. The left swing of the support plate 6 drives the upper and lower one-dimensional hole plates 8 to swing towards each other through the rotating shaft 5. The one-dimensional hole plates 8 drive the upper and lower sleeves 81 to move towards each other. The sleeves 81 pass through The slide bar 82 drives the wedge blocks 84 on the upper and lower sides to move toward each other and disengage from the through hole 83. The compression spring 85 is compressed, and the wedge block 84 stops locking the guide plate 3. The upper and lower guide plates 3 can be moved to the right and removed to complete the disassembly. The support plate 6 is loosened. Due to the action of the compression spring 85, the wedge blocks 84 on the upper and lower sides move away from each other and reset. The wedge block 84 drives the upper and lower sleeves 81 on the upper and lower sides to move away from each other and reset through the slide bar 82. The sleeve 81 drives the slotted plate 8 to swing and reset. The slotted plate 8 drives the support plate 6 to swing and reset through the rotating shaft 5. , the disassembled guide plate 3 can be carried together with the support frame 1 and the electric lifting frame 2 to the next position for scenery display. Due to the effect of the limit block 107, the telescopic movable rod 105 can be prevented from falling from the fixed guide plate 106 and affecting the carrying. When the scenery needs to be displayed, the two guide plates 3 are moved to the left and inserted into the support frame 1 and the electric lifting frame 2 respectively. The guide plate 3 moves to the left and contacts the wedge block 84. The guide plate 3 drives the upper and lower wedge blocks 84 to move in a direction close to each other. The compression spring 85 is compressed, and the guide plate 3 continues to move to the left so that the through hole 83 and the wedge block 84 are in contact. When corresponding, due to the action of the compression spring 85, the wedge blocks 84 on the upper and lower sides move in a direction away from each other and reset into the through hole 83. The wedge blocks 84 lock the guide plate 3 through the through hole 83, and then pull the sliding sleeve 7 to move so that the reset spring 71 is compressed, and then pull the upper and lower swing rods 4 to swing inward to the inside of the support plate 6, release the sliding sleeve 7, and due to the action of the reset spring 71, the sliding sleeve 7 slides and contacts the support plate 6. The sliding sleeve 7 cooperates with the support plate 6 to lock the swing rod 4, and the locking of the guide plate 3 is completed. In this way, a quick installation can be completed, so that the scenery display can be quickly carried out. When the scenery display is completed, the guide plate 3 can be quickly removed according to the above operation. In this way, it is convenient to disassemble and assemble and facilitate the overall movement, thereby improving the flexibility and efficiency of scenery display.

[0035] See also Figure 8-Figure 10As shown, the variable scenery display device for interior design also includes a support assembly installed on the support frame 1, the support assembly includes a frame 11, a cylinder 111, a support rod 112, a buffer spring 1121, a roller 1122 and a driving assembly, the frame 11 is fixedly connected to the left side of the front and rear sides of the support frame 1, the upper parts of the front and rear frames 11 are rotatably connected to the cylinder 111, and the inner side of the cylinder 111 is slidably connected to the support rod 112. When the support rod 112 is swung outward and unfolded, the support rod 112 can support and limit the support frame 1, and a buffer spring 1121 is connected between the top of the support rod 112 and the top of the cylinder 111, and the bottom ends of the front and rear support rods 112 are rotatably connected to the roller 1122. When 112 is unfolded, the roller 1122 can guide the support rod 112 to reduce the friction with the ground. A driving assembly is arranged between the frame 11 and the cylinder 111. When the driving assembly is in operation, the driving assembly can drive the cylinder 111 to swing; the driving assembly includes a connecting rod 113, a movable seat 114 and a driving screw 115. The lower part of the front and rear frames 11 is slidably connected with the movable seat 114, and the left and right sides of the movable seat 114 are rotatably connected with the connecting rod 113, the connecting rod 113 is located outside the frame 11, and the top ends of the connecting rods 113 on the left and right sides are rotatably connected with the middle part of the outer side surface of the cylinder 111, and the top of the frame 11 is rotatably connected with the driving screw 115, and the driving screw 115 is threadedly connected to the middle part of the movable seat 114.

[0036] Initially, the buffer spring 1121 is in a compressed state. When the device moves to the position for displaying the scenery, the screw rod 115 is twisted to rotate forward. The screw rod 115 rotates forward to drive the movable seat 114 to move upward. The movable seat 114 moves upward to drive the front and rear cylinders 111 to swing outward through the connecting rod 113. The front and rear cylinders 111 swing outward to drive the front and rear support rods 112 to swing outward. The front and rear support rods 112 swing outward to drive the front and rear rollers 1122 to swing outward. Due to the action of the buffer spring 1121, the support rods 112 always press against the rollers 1122. 122 applies pressure so that roller 1122 keeps rolling close to the ground, and roller 1122 guides support rod 112 to swing outward to reduce the friction between support rod 112 and the ground, making support rod 112 swing outward more smoothly. When movable seat 114 moves upward to the maximum stroke, the driving screw 115 stops twisting, movable seat 114 stops moving upward, cylinder 111 stops driving support rod 112 to swing outward, and support rod 112 cooperates with cylinder 111 to support and limit support frame 1, which makes the device more stable to use. When the scenery display is not needed, the twisting driving screw 115 is reversed to drive the movable seat 114 to move downward and reset. The movable seat 114 resets and drives the front and rear barrels 111 to swing inward and reset through the connecting rod 113. The barrel 111 drives the front and rear support rods 112 to swing inward and reset. The support rods 112 swing inward and drive 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 rods 112, and the twisting driving screw 115 is stopped. In this way, the shaking phenomenon that occurs during the use of the device and affects the scenery display can be prevented, thereby making the device more stable to use.
