Preferably, a hand wheel is fixed at one end, far away from the rack, of the threaded rod.
Preferably, a sliding groove is formed in the mounting plate, a sliding block is arranged on one side of the rack, and the sliding block is connected in the sliding groove in a sliding mode.
Preferably, when the slider is located the one end of spout, LCD module and mounting panel mutually perpendicular, when the slider is located the other end of spout, LCD module and mounting panel are parallel to each other.
Preferably, four corners of the mounting plate are provided with mounting holes.
Preferably, the connecting seat is arranged close to one end of the liquid crystal display module.
Preferably, the liquid crystal display module is of a square structure.
Preferably, the connecting seat is fixedly connected with the liquid crystal display module through screws.
Compared with the prior art, the beneficial effects of the utility model are that: the threaded rod is driven to rotate by rotating the hand wheel, the rack is driven to slide relative to the mounting plate, the rack is connected with the gear in a meshed mode, the connecting seat and the liquid crystal display module are enabled to rotate together along the driving shaft, and when the sliding block is located at one end of the sliding groove, the liquid crystal display module is perpendicular to the mounting plate, so that the liquid crystal display module can be replaced and maintained conveniently.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a seamless concatenation screen of DID large screen liquid crystal, includes mounting panel 1 and liquid crystal display module 8, one side both ends of mounting panel 1 are fixed with first mount pad 2 and second mount pad 3 respectively the equidistance, it is connected with drive shaft 4 to rotate between first mount pad 2 and the second mount pad 3, the one end of drive shaft 4 is fixed with gear 5, the drive arrangement 6 that is used for drive gear 5 is installed to mounting panel 1 one side, the outside equidistance of drive shaft 4 cup joints and is fixed with connecting seat 7, the one end of connecting seat 7 is fixed with liquid crystal display module 8, and a plurality of liquid crystal display module 8 is array distribution.
Referring to fig. 2-3, the driving device 6 includes an ear plate 9, a threaded rod 10 and a rack 11, the ear plate 9 is fixed on the mounting plate 1, the threaded rod 10 is rotatably connected in the ear plate 9 through a bearing, the rack 11 is slidably connected to one side of the mounting plate 1, the rack 11 is meshed with the gear 5, a threaded hole is formed in one end of the rack 11, and one end of the threaded rod 10 is meshed with the threaded hole through a thread.
Referring to fig. 2, a hand wheel 12 is fixed at one end of the threaded rod 10 away from the rack 11, so as to drive the threaded rod 10.
Referring to fig. 4, a sliding groove 13 is formed in the mounting plate 1, a sliding block 14 is arranged on one side of the rack 11, and the sliding block 14 is slidably connected in the sliding groove 13, so that the rack 11 moves more stably.
When the sliding block 14 is located at one end of the sliding groove 13, the liquid crystal display module 8 is perpendicular to the mounting plate 1, and when the sliding block 14 is located at the other end of the sliding groove 13, the liquid crystal display module 8 is parallel to the mounting plate 1, so that the liquid crystal display module 8 can be spliced into a seamless state conveniently.
Referring to fig. 4, four corners of the mounting plate 1 are provided with mounting holes 15, so that the mounting plate 1 can be conveniently fixed on a wall.
Referring to fig. 3, the connecting seat 7 is disposed near one end of the liquid crystal display module 8, so as to reduce the overall thickness of the DID large-screen liquid crystal seamless splicing screen.
