[0056] As explained in the background technology, in the related art, there are problems with inconvenient splicing and difficulty in adjusting the splicing gap when splicing multiple screens. Technical personnel have found that the reason for this problem is that in the related technology, the first bracket set on the back of the first display screen and the second bracket set on the back of the second display screen are fixedly connected and cannot be adjusted, resulting in inconvenient splicing and difficulty in adjusting the splicing gap.

[0057] In response to the above technical problems, an embodiment of the present application provides a multi-screen splicing device, which includes at least a first display screen and a second display screen that are spliced ​​together. A first connecting member and a second connecting member that are hinged to each other are arranged at the splicing point of the first display screen and the second display screen, and the first connecting member is controlled to rotate below the first display screen, thereby driving the second connecting member to displace while rotating, and driving the first display screen and the second display screen to displace, thereby adjusting the splicing gap between the first display screen and the second display screen. The structure is simple and easy to operate.

[0058] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0059] The present application embodiment provides a multi-screen splicing device, referring to Figure 1-Figure 3 , Figure 1 A schematic diagram of a structure in which a connection component of a multi-screen splicing device provided in an embodiment of the present application is arranged on a first display screen and a second display screen, Figure 2 A schematic diagram of an exploded structure in which the connecting components of the multi-screen splicing device provided in an embodiment of the present application are arranged on the first display screen and the second display screen, Figure 3A schematic diagram of the structure of the first connecting member, the second connecting member and the third connecting member provided in an embodiment of the present application. The multi-screen splicing device comprises at least a first display screen 100 and a second display screen 200 that are spliced ​​together, and a connecting component 300 of the multi-screen splicing device is arranged on the first display screen 100 and the second display screen 200, and is used to control the first display screen 100 and the second display screen 200 to achieve splicing.

When the second connecting member 302 moves to the first position, the first display screen 100 and the second display screen 200 are spliced. By arranging the first connecting member 301 and the second connecting member 302 which are hinged to each other at the splicing position of the first display screen 100 and the second display screen 200, and controlling the first connecting member 301 to rotate below the first display screen 100, so as to drive the second connecting member 302 to generate displacement while rotating, so as to adjust the splicing gap between the first display screen 100 and the second display screen 200, the structure is simple and easy to operate; at the same time, it can also ensure that the first display screen 100 and the second display screen 200 remain as flat as possible during the splicing process.
