It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0015] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0016] like Figure 1-Figure 6As shown, it is a structural diagram of a conference room stable lifting display device provided by an embodiment of the present invention, comprising a bottom box 1, a lifting mechanism 100, a tripod bracket 10, a dustproof mechanism 200 and a synchronous adjustment mechanism 300, wherein the lifting mechanism 100 is arranged in the bottom box 1, and the movable end of the lifting mechanism 100 is slidably connected to the inner wall of the bottom box 1; the tripod bracket 10 is fixedly installed on the horizontal rod 8 in the lifting mechanism 100 by bolts, and the top of the tripod bracket 10 is fixedly connected with a shell 11, and a plurality of display screen bodies 16 are arranged on the side of the shell 11; the dustproof mechanism 200 is installed on the top of the bottom box 1, and the dustproof mechanism 200 is in an unfolded state when the display screen body 16 is lifted or lowered; the synchronous adjustment mechanism 300 is arranged on the tripod bracket 10, and the free end of the synchronous adjustment mechanism 300 is connected to the display screen body 16, so as to adjust the distance between adjacent display screen bodies 16 during operation, thereby meeting different display requirements.

[0017] In an example of the present invention, baffles 2 are symmetrically installed on both sides of the bottom box 1, and a groove is opened on the tabletop of the conference room so that the bottom box 1 and the baffles 2 can be installed as a whole on the conference table.

[0018] like Figure 1 As shown, as a preferred embodiment of the present invention, the lifting mechanism 100 includes a driving screw 3, a gear shaft 4, a bevel gear 5, a screw sleeve 6, a movable rod 7 and a horizontal rod 8; The driving screws 3 are arranged in pairs and are rotatably mounted on the bottom box 1 respectively. The driving screws 3 on both sides are transmission-connected to the gear shaft 4 rotatably arranged at the bottom end of the bottom box 1 through the bevel gear 5. The horizontal rod 8 is slidably mounted on the inner wall of the bottom box 1, and a longitudinal slide groove 9 is provided in the bottom box 1 for the horizontal rod 8 to move; The bottom end of the horizontal rod 8 is hinged with a movable rod 7, which is hinged to a screw sleeve 6 arranged on the driving screw 3, so that when the driving screws 3 on both sides rotate, the horizontal rod 8 can be pushed up and down along the bottom box 1 by the arranged movable rod 7.

[0019] In one example of the present invention, the gear shaft 4 is connected to an external motor through a coupling, and the motor is also connected to an operating platform 18 arranged on the baffle 2, so that when the motor is working, the gear shaft 4 is driven to rotate longitudinally along the bottom box 1. The gear shaft 4 also drives the driving screw 3 to rotate horizontally along the bottom box 1 through the arranged bevel gear 5. The driving screws 3 on both sides push the screw sleeves 6 to move in opposite directions, thereby pushing the movable rod 7 to swing in a plane, and finally making the horizontal rod 8 slide in the height direction along the longitudinal slide groove 9 opened on the inner side of the bottom box 1, so as to adjust the position of the outer shell 11 and the display screen body 16.

[0020] like Figure 2 and Figure 3 As shown in FIG. 1 , as another preferred embodiment of the present invention, the dustproof mechanism 200 includes an oblique blocking rod 12, a top groove 13, a flap 14 and an elastic lever 15; The oblique blocking rod 12 is fixedly mounted on the side of the housing 11, and a top groove 13 is provided at the top of the bottom box 1 for the housing 11 and the display screen body 16 to pass through; A flap 14 is hinged on the top groove 13 , and one end of the flap 14 is connected to the end of an elastic lever 15 installed in the bottom box 1 to prevent dust from accumulating on the surface of the display screen body 16 when not in use.

[0021] In one example of the present invention, when the display screen body 16 extends out of the bottom box 1, the oblique blocking rod 12 moves synchronously with the outer shell 11, the flap 14 flips outward, and the elastic lever 15 is stretched by force. When the display screen body 16 retracts into the bottom box 1, the flap 14 returns to its initial position under the action of the elastic lever 15 and is at the same horizontal plane as the top of the bottom box 1, thereby preventing dust from passing through the top groove 13 and falling on the mechanism inside the bottom box 1.

[0022] like Figure 2 As shown, as another preferred embodiment of the present invention, a plurality of evenly distributed nozzles 17 are also installed on the top of the bottom box 1, and the nozzles 17 are connected to the built-in air pump of the bottom box 1 through a hose; The air pump is electrically connected to an external operating platform 18 , and controls the flow of gas through the operating platform 18 to blow away dust attached to the surface of the display screen body 16 .

[0023] In one embodiment of the present invention, the display screen body 16 is retracted into the bottom box 1 after each use. When the display screen body 16 passes through the nozzle 17, the built-in air pump works to blow away the dust attached to the surface of the display screen body 16, thereby ensuring the cleanliness of the surface of the display screen body 16.

[0024] like Figure 4 and Figure 5 As shown, as another preferred embodiment of the present invention, the synchronous adjustment mechanism 300 includes a driving gear shaft 20, a driven gear shaft 1 21, an inner gear ring 22, a driven gear shaft 23 and a single-sided gear plate 24; The inner gear ring 22 is rotatably mounted in the housing 11, and the driving gear shaft 20, the driven gear shaft 1 21 and the driven gear shaft 2 23 are rotatably mounted on the housing 11, wherein the driven gear shaft 1 21 and the driven gear shaft 2 23 are both meshed with the inner side of the inner gear ring 22, and the driving gear shaft 20 is also mounted on the inner side of the driven gear shaft 1 21; The driven gear shaft 23 is in meshing state with the single-sided toothed plate 24 slidably mounted on the housing 11, and a plurality of single-sided toothed plates 24 are fixedly connected to the display screen bodies 16 at corresponding positions, so as to adjust the positions of adjacent display screen bodies 16 when the single-sided toothed plates 24 slide.

[0025] In one example of the present invention, the driving gear shaft 20 is driven by a tool box 19 installed in the housing 11 , and the tool box 19 is also connected to the display screen body 16 at a corresponding position via a data line 25 arranged in a single-sided gear plate 24 .

[0026] Under normal circumstances, multiple display screen bodies 16 are spliced ​​together to form a large screen for participants to use as a large screen. When the meeting needs to present different contents separately, the micro motor built into the tool box 19 can be operated through the operating platform 18 to drive the driving gear shaft 20 to rotate along the outer shell 11. Since the driving gear shaft 20 is engaged with the driven gear shaft 1 21, and the driven gear shaft 1 21 is engaged with the inner gear ring 22, the driven gear shaft 1 21 and the inner gear ring 22 can be driven to rotate along the outer shell 11 in turn. The inner gear ring 22 simultaneously drives the driven gear shaft 2 23 at multiple positions to rotate synchronously, and then promotes the single-sided gear plate 24 and the display screen body 16 at the corresponding position to move synchronously, so as to adjust the spacing between adjacent display screen bodies 16, so that the large screen is broken down into parts, and the content is output on multiple display screen bodies 16 through the data line 25 to meet the meeting needs.

[0027] To sum up, in actual use, the external motor is operated through the operating platform 18, and the motor drives the gear shaft 4 to rotate longitudinally along the bottom box 1. The gear shaft 4 also drives the driving screw 3 to rotate horizontally along the bottom box 1 through the arranged bevel gear 5. The driving screws 3 on both sides push the screw sleeves 6 to move in opposite directions, thereby pushing the movable rod 7 to swing in a plane, and finally making the horizontal rod 8 slide in the height direction along the longitudinal slide groove 9 opened on the inner side of the bottom box 1, and adjusting the position of the shell 11 and the display screen body 16. After reaching the specified height, the external motor stops working. During the process, when the display screen body 16 extends out of the bottom box 1, the oblique blocking rod 12 moves synchronously with the shell 11, the flap 14 flips outward, and the elastic lever 15 is stretched by force. Under normal circumstances, multiple display screen bodies 16 are spliced ​​together to form a large screen for the participants to use as a large screen. When the meeting needs to present different contents separately, the micro motor built in the tool box 19 can be driven by the operating platform 18 to drive the driving gear shaft 20 to rotate along the shell 11. Since the driving gear shaft 20 is meshed with the driven gear shaft 21, the driven gear shaft 21 is meshed with the inner gear shaft 16. The meshing of the gear ring 22 can drive the driven gear shaft 1 21 and the inner gear ring 22 to rotate along the housing 11 in turn, and the inner gear ring 22 can simultaneously drive the driven gear shafts 23 at multiple positions to rotate synchronously, thereby promoting the single-side toothed plate 24 and the display screen body 16 at the corresponding position to move synchronously, so as to adjust the spacing between adjacent display screen bodies 16, so that the large screen is decomposed into multiple small screens. After the meeting, the multiple display screen bodies 16 are combined and retracted into the bottom box 1. When the display screen body 16 passes through the nozzle 17, the built-in air pump works to blow away the dust attached to the surface of the display screen body 16. When the display screen body 16 is retracted into the bottom box 1, the flap 14 returns to its initial position under the action of the elastic lever 15 and is at the same level as the top of the bottom box 1, thereby preventing dust from passing through the top groove 13 and falling on the components inside the bottom box 1; the display device can freely adjust the working height as needed when used in a conference room, and adopts a splicing method to form a display screen, which can not only realize large-screen display, but also split the screen for detailed presentation, which can meet different meeting needs, and the display screen body 16 can be dust-proofed before and after it is extended, avoiding dust accumulation while reducing the difficulty of cleaning.

[0028] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
