[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1 to Figure 3 In an embodiment of the utility model, a lifting device for a display comprises a vertical rail 1 with a first slideway provided inside, the bottom end of the first slideway is a closed structure, a support plate 3 is slidably connected to the inside of the first slideway, a winding mechanism for driving the display box to move up and down is distributed on the vertical rail 1 and the support plate 3, a one-way driving mechanism is installed inside the winding mechanism, and the one-way driving mechanism is used to drive the winding mechanism to wind or unwind;

[0025] The vertical rail 1 is connected to the edge wall of the roof through a first extrusion mechanism, and a second extrusion mechanism for limiting the top of the box is installed at one end of the support plate 3 close to the vertical rail 1;

[0026] A cross bar 2 is installed at one end of the top of the vertical rail 1 away from the supporting plate 3 .

[0027] In this embodiment: first, the device is limited on the rooftop wall by the first squeezing mechanism, wherein the vertical rail 1 is located on the outer wall, and then the outdoor LED display is hoisted to a preset height by the hoisting device. At this time, the bottom of the display should be flush with the top height of the support plate 3, and then the display is transferred to the device with manual assistance (during the transfer process, the safety of the display should be fully guaranteed, and the display can be connected by a safety rope);

[0028] At this time, the bottom of the display box is located at the top of the support plate 3 (note that the safety rope of the display does not need to be released), and then the second pressing mechanism is used to press the top of the display box. After pressing, the winding rope is wound up by the winding device, thereby pulling the support plate 3 to move upward along the first slide of the vertical rail 1 until the display box is lifted to the preset position, and the display and the outer wall can be installed.

[0029] Please refer to Figure 1 and Figure 2 The winding mechanism includes a fixed pulley 4 rotatably connected to the top of the vertical rail 1 through a rotating seat, a connecting plate 5 vertically arranged with the vertical rail 1 is welded to the top of the outer side of the vertical rail 1, and a winding disc 6 is rotatably connected to the top of the connecting plate 5 through a rotating seat, and a transmission shaft 18 is coaxially connected between the two winding discs 6, and the transmission shaft 18 is rotatably connected to the rotating seat through a bearing;

[0030] An opening is formed at one end of the support plate 3 away from the vertical rail 1, and a rotating ear 17 is rotatably connected to the inner side of the opening. A winding rope is provided on the winding mechanism, one end of the winding rope is connected to the annular portion of the rotating ear 17, and the other end of the winding rope is connected to the winding drum 6, and the winding rope is in contact with the upper outer wall of the fixed pulley 4.

[0031] In this embodiment: by rotating the one-way driving mechanism, the two winding drums 6 are driven to rotate synchronously and in the same direction, the winding drums 6 wind up the winding rope, and the winding rope pulls the support plate 3 along the first slideway of the vertical rail 1 upward through the rotating ear 17;

[0032] In the above process, the fixed pulley 4 can support the bending point of the winding rope to prevent the winding rope from having hard friction with the vertical rail 1.

[0033] Please refer to Figure 1 and = Figure 2 The one-way driving mechanism includes a worm wheel 8 which is interference fitted in the middle section of the outer wall of the transmission shaft 18, and a mounting plate 7 is fixedly connected between two rotating seats connected to the winding disk 6 by bolts. A worm 9 which meshes with the worm wheel 8 is rotatably mounted on one end of the mounting plate 7, and a crank 10 is mounted on one end of the worm 9.

[0034] In this embodiment: by rotating the crank 10, the crank 10 drives the worm 9 to rotate, and when the worm 9 rotates, it drives the worm wheel 8 to rotate, and the worm wheel 8 drives the transmission shaft 18 to rotate, and the transmission shaft 18 can drive the two winding disks 6 to rotate, thereby realizing the winding or unwinding of the winding rope.

[0035] Please refer to Figure 3 The first extrusion mechanism includes a sliding sleeve 19 slidably connected to the outer wall of the crossbar 2, and a first extrusion plate 20 is welded to the bottom end of the sliding sleeve 19;

[0036] An anti-slip portion is formed at one end of the cross bar 2 away from the vertical rail 1, and a first fixing plate 21 is welded to the bottom end of the anti-slip portion. A screw hole is opened inside the first fixing plate 21, and a first stud 22 rotatably connected to the first extrusion plate 20 is threadedly connected in the screw hole. A first handle 23 is installed at one end of the first stud 22.

[0037] In this embodiment: by rotating the first handle 23, the first handle 23 drives the first stud 22 to rotate. Since the first fixing plate 21 is fixed in position and the first fixing plate 21 and the first stud 22 are threadedly connected, the first stud 22 moves axially while rotating, thereby pushing the first extrusion plate 20 to move, until the first extrusion plate 20 cooperates with the vertical rail 1 to effectively clamp the inner and outer sides of the rooftop wall, and the position of the vertical rail 1 can be limited at this time.

[0038] Please refer to Figure 1 and Figure 2 The second extrusion mechanism includes a sleeve 11 fixedly connected to one end of the support plate 3 close to the vertical rail 1, and the inner wall of the sleeve 11 is slidably connected to a sliding rod 12 up and down;

[0039] The outer wall of the sliding rod 12 is provided with a vertical second slideway, and a second extrusion plate 14 is connected to the second slideway for vertical sliding movement;

[0040] A second fixing plate 13 is welded to the top of the sliding rod 12 . A screw hole is provided inside the second fixing plate 13 . A second stud 15 rotatably connected to the second extrusion plate 14 is threadedly connected in the screw hole. A second handle 16 is mounted on one end of the second stud 15 .

[0041] In this embodiment: after the display box is transferred to the support plate 3, the second handle 16 is rotated, and the second handle 16 drives the second stud 15 to rotate. Since the second fixing plate 13 is fixed in position and the second fixing plate 13 and the second stud 15 are threadedly connected, the second stud 15 moves axially while rotating, thereby pushing the second extrusion plate 14 to move until the second extrusion plate 14 contacts the top of the display box. At this time, the support plate 3 and the second extrusion plate 14 cooperate to limit and clamp the display box to prevent the display box from shaking.

[0042] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
