This application proposes a middle frame splicing structure.

Please refer to FIGS. 1 to 7 in combination. In an embodiment of the splicing structure of the middle frame 100 of the present application, the splicing structure of the middle frame 100 includes:

A first frame 110, the first frame 110 has a first slot 111, and the first slot 111 extends along the length direction of the first frame 110;

A second frame 120, the second frame 120 has a second card slot 121, and the second card slot 121 extends along the length direction of the second frame 120;

The first connecting member 130 has a first connecting portion 131 and a second connecting portion 132 connected to each other, and the first connecting portion 131 is engaged with one end of the first slot 111, so The second connecting portion 132 is engaged with the second slot 121 to realize the splicing of the second frame 120 and the first frame 110 through the first connecting member 131.

The splicing structure of the middle frame 100 includes a first frame 110, a second frame 120, and a first connecting piece 130. The first frame 110 and the second frame 120 are connected to each other. The connection point of the second frame 120. The first frame and the second frame can be an oval structure, a rectangular structure, a straight plate structure, a straight plate bending structure, etc. The splicing form of the first frame and the second frame can be set at a right angle perpendicular to each other, or it can be an obtuse angle or an obtuse angle. The form of acute angle setting, as long as the two abutting and fixing can be realized, so as to splice the frames required by various shapes. Specifically, the first frame 110 is provided with a first card slot 111, the first card slot 111 extends along the length direction of the first frame 110, and both ends of the first card slot 111 penetrate the outer surface of the first frame 110, The second frame 120 is provided with a second card slot 121, the second card slot 121 extends along the length of the second frame 120, and both ends of the second card slot 121 penetrate the outer surface of the second frame 120. One end of the second frame 120 is connected to one end of the first frame 110, so that the first slot 111 and the second slot 121 are communicated and arranged to increase the tightness of the splicing of the first frame and the second frame. The first frame 110 and the second frame 120 are connected by a first connecting member 130. The first connecting member 130 has a first connecting portion 131 and a second connecting portion 132. The first connecting portion 131 is directly engaged in the first slot 111 , The second connecting portion 132 is engaged with an end of the second slot 121 close to the first slot 111, so as to realize the connection and fixation of the first frame 110 and the second frame.

The sides of the first frame 110 and the second frame 120 are still side panels, which can reduce the splicing gaps on the sides of the traditional middle frame 100 splicing structure. When the traditional middle frame 100 is spliced, the first frame 110 and the second frame 120 are spliced Splicing gaps are prone to occur, and too large gaps will affect the display effect of the TV display device. Therefore, in the present application, a first connector 130 is provided between the first frame 110 and the second frame 120, and the first connector 130 is provided on the first frame. The joint of the frame 110 and the second frame 120 can be used to fill the joint gap between the first frame 110 and the second frame 120, so as to achieve the purpose of reducing the joint gap of the middle frame 100.
