[0035] The following is combined with Figure 1-6 This application is described in further detail.

[0036] The present application embodiment discloses a workshop digital large screen lifting and adjusting device. Figure 1 and Figure 2 The splicing screen lifting seat includes a base 1, a linkage rod 11 and a mounting seat 14. A plurality of mounting seats 14 are arranged circumferentially on the base 1. The base 1 is movably connected to the mounting seat 14 through the linkage rod 11. The mounting seat 14 is used to connect the splicing screen 15. Several splicing screens 15 are arranged axially around the base 1 to facilitate 360-angle display and reduce display blind spots. A USB hub (not shown in the figure) is installed on the base 1. The USB hub can switch the USB upstream port to connect with any USB downstream port. The USB downstream port connects each splicing screen 15 through a data cable, and the USB upstream port connects the keyboard and mouse, so that devices such as the keyboard and mouse can be connected to any splicing screen 15 separately.

[0037] In the embodiment of the present application, the linkage rod 11 includes a first link 12 and a second link 13 which are parallel to each other, and the first link 12 and the second link 13 are not colinear. One end of each of the first link 12 and the second link 13 is hinged to the base 1, and the other ends of each of the first link 12 and the second link 13 are hinged to the mounting seat 14. In addition, the spacing between the hinge axes at both ends of the first link 12 is the same as the spacing between the hinge axes at both ends of the second link 13. A control device 2 for controlling the flipping of the first link 12 is provided on the base 1. During the flipping process of the first link 12, under the transmission action of the first link 12 and the second link 13, the mounting seat 14 can maintain a constant angle during the flipping process.

[0038] like Figure 3 and Figure 4 The control device 2 includes a sleeve 21 slidably sleeved on the base 1, a push rod 22 is hinged on the sleeve 21, and the other end of the push rod 22 is hinged on the first connecting rod 12. A stud 23 is rotatably connected to the base 1, and a motor 24 for controlling the rotation of the stud 23 is also provided inside the base 1. The stud 23 and the sleeve 21 are connected in a transmission manner through a linkage assembly, thereby pushing the sleeve 21 to move axially on the base 1.

[0039] The linkage assembly includes a roller 25, a mounting groove is provided at the top of the base 1, the roller 25 is located in the mounting groove, a cable 26 is wound around the roller 25, one end of the cable 26 is fixedly connected to the sleeve 21, and a counterweight is provided on the sleeve 21, and the other end of the cable 26 is fixedly connected to a screw sleeve 27, which can be sleeved on the stud 23 and threadedly connected with the stud 23. A pull rod 28 is fixedly connected to the screw sleeve 27, and the pull rod 28 is axially slidable and penetrated in the base 1, and the base 1 can limit the rotation of the pull rod 28. The end of the pull rod 28 away from the base 1 is fixedly connected to a flange 29, and the flange 29 is used to connect to the target device. When the motor 24 rotates, the stud 23 is driven to rotate, and then the screw sleeve 27 is driven to move along the axial direction of the stud 23, so as to achieve the telescopic effect of the pull rod 28 on the base 1.

[0040] The movement of the screw sleeve 27 drives the cable 26 to move. When the screw sleeve 27 is lifted by the stud 23, the sleeve 21 moves downward under the action of the counterweight, and then drives the first connecting rod 12 and the second connecting rod 13 to flip downward under the action of the push rod 22, so that the mounting seat 14 moves downward, achieving the effect of lowering the spliced ​​screen 15. When the screw sleeve 27 moves downward under the action of the stud 23, the sleeve 21 moves upward under the traction of the cable 26, and then drives the first connecting rod 12 and the second connecting rod 13 to flip upward under the action of the push rod 22, so that the mounting seat 14 moves upward, achieving the effect of lifting the spliced ​​screen 15.

[0041] like Figure 5 and Figure 6 A workbench 31 is foldably provided on the mounting seat 14. When the user needs to debug the spliced ​​screen 15, the workbench 31 can be used to place devices such as a keyboard and a mouse. The workbench 31 can be foldably provided, so that it is convenient to store.

[0042] In order to increase the practicality and flexibility of the workbench 31, a lifting frame 3 is vertically slidably provided on the side of the mounting seat 14 away from the splicing screen 15, and the workbench 31 is hinged on the lifting frame 3. A limit plate 32 is provided on the lifting frame 3 to limit the flipping angle of the workbench 31. When the workbench 31 flips to a horizontal state, the workbench 31 can be supported on the limit plate 32, so that the operator can place items on the workbench 31.

[0043] The implementation principle of the embodiment of the present application is as follows: the motor 24 drives the stud 23 to rotate, thereby driving the screw sleeve 27 to move, and under the action of the cable 26 and the counterweight, the sleeve 21 is driven to rise and fall, thereby driving the push rod 22 and the linkage rod 11 to flip, so as to achieve the lifting and lowering of the splicing screen 15, which can meet the needs of users at different heights, so that the operator can disassemble and replace the splicing screen 15 and debug the splicing screen 15.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
