[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0036] Example 1

[0037] Reference Figure 1-9, which is the first embodiment of the present invention, provides a visual display device for land space planning, the visual display device for land space planning comprises a storage seat 1, a lifting drive assembly 4 is arranged on one side of the bottom of the storage seat 1, a lifting seat 8 is arranged above the lifting drive assembly 4, a display screen 7 is arranged vertically slidingly inside the storage seat 1, the bottom of the display screen 7 is located on the upper end surface of the lifting seat 8, the lifting drive assembly 4 is used to drive the lifting seat 8 and the display screen 7 to lift vertically, two groups of sliders 84 are arranged slidingly above the lifting seat 8, each group of sliders 84 is connected with a reinforcing plate 81 respectively, two fixing sleeves 71 are parallelly installed on one side of the display screen 7 close to the reinforcing plate 81, a sliding column 82 is slidably arranged in the fixing sleeve 71, a through groove 72 is opened below the fixing sleeve 71, the two ends of the through groove 72 respectively penetrate to the end of the fixing sleeve 71, the sliding column 82 is connected to the corresponding reinforcing plate 81, the lifting drive assembly 4 is used to drive the slider 84 to move from left to right or from right to left, the one-way moving length of the slider 84 is less than the length of the fixing sleeve 71, due to the two fixing sleeves 71 , and the lifting seat 8 is lifted up, so that the display screen 7 is lifted up from the top of the storage seat 1. At the same time, the sliding column 82 of one of the reinforcing plates 81 slides from left to right in the fixing sleeve 71, and the other sliding column 82 slides from right to left in the corresponding fixing sleeve 71. When the display part of the display screen 7 is completely exposed, the bottom of the display screen 7 is still located in the storage seat 1. At this time, the sliding column 82 has not completely slid out of the fixing sleeve 71. When the lifting drive assembly 4 is continued to be controlled to make the lifting seat 8 continue to move upward, the two sliding columns 82 completely slide out of the corresponding fixing sleeve 71 respectively. At this time, the fixing sleeve 71 and the display screen 7 can be pulled upward as a whole, so that the display screen 7 and the storage seat 1 can be conveniently disassembled. An angle structure is formed between the two reinforcing plates 81 and the lifting seat 8, which can ensure the stability of the display screen 7 when the display screen 7 is lifted out of the display state.

[0038] Combined with Figure 4 and Figure 5 The side wall of the display screen 7 is provided with a stopper 73 which is rotated by a torsion spring. The stopper 73 is located at the end of one of the fixing sleeves 71. Under normal conditions, the stopper 73 is blocked at one end of one of the fixing sleeves 71 to prevent the corresponding slide post 82 from accidentally sliding out of the fixing sleeve 71 when the display screen 7 is rising upward. Before the display screen 7 needs to be disassembled, the torsion spring of the stopper 73 is rotated so that there is no obstruction at the end of the fixing sleeve 71, and the slide post 82 can slide out of the fixing sleeve 71.

[0039] Combined with Figure 7A T-shaped groove is provided on one side of the storage seat 1 close to the lifting seat 8, and the display screen 7 is positioned in the groove. The side of the lifting seat 8 close to the storage seat 1 is a T-shaped structure, and the T-shaped structure of the lifting seat 8 is limited in the groove of the storage seat 1. The lifting of the display screen 7 depends on the upward lifting force of the lifting seat 8, and the stable non-tilted state of the display screen 7 depends on the limitation of the storage seat 1 and the reinforcing plate 81.

An end block 42 is installed at one end of the screw rod 41, and a positioning block 44 is movably connected to the other end of the screw rod 41. The self-locking box 43, the screw rod 41, the end block 42 and the positioning block 44 form a horizontal screw lift. When the self-locking box 43 is running, the screw rod 41 moves from the end block 42 to the positioning block 44. A second connecting rod 46 is movably installed on the top of the end block 42 through a pin shaft. The top of the second connecting rod 46 is movably connected to one side of the bottom of the lifting seat 8 through a pin shaft. The top of the self-locking box 43 is movably connected with the first connecting rod 45 through a pin shaft. When the self-locking box 43 starts to operate, due to the axial movement of the screw rod 41, the second connecting rod 46 rotates to lift the lifting seat 8 upward, thereby rotating the first connecting rod 45, so that the slider 84 slides in the slide rail 83. The slide rail 83 is opened at the position corresponding to the slider 84 on the reinforcing plate 81. The bottom of the slider 84 passes through the slide rail 83 to the bottom of the lifting seat 8. The extended end of the first connecting rod 45 is movably connected to the slider 84 using a pin shaft. The slider 84 has a T-shaped structure. A T-shaped slide groove 11 is provided at the bottom of the storage seat 1. Preferably, the cross section of the T-shaped slide groove 11 is a T-shaped structure. The bottom of the end block 42 is a T-shaped structure. The bottom of the end block 42 is limited to slide horizontally in the T-shaped slide groove 11. Two groups of horizontal screw lifts are arranged diagonally. A motor 47 for driving a self-locking box 43 of one of the horizontal screw lifts is installed at the bottom of the storage seat 1. The input shafts of the two horizontal screw lift self-locking boxes 43 are connected by a synchronous belt 5. The self-locking boxes 43 of the two horizontal screw lifts are divided into They are located on the left and right sides respectively. When in use, the two self-locking boxes 43 are operated by controlling the motor 47, and the two screw rods 41 move one to the left and the other to the right, so that the lifting seat 8 is lifted upward. At the same time, the two reinforcing plates 81 move one to the left and the other to the right, and the display screen 7 is lifted on the lifting seat 8. After the display area of ​​the display screen 7 is fully exposed, the bottom of the display screen 7 is still in the storage seat 1, and the back side of the display screen 7 is pulled and controlled by the two reinforcing plates 81, thereby ensuring a stable visual display of the display screen 7.
