As shown in fig. 6, by implementing the above technical solution, the first connecting member 10 and the second connecting member 20 can be connected and fixed by the first corner connecting portion 11 and the second corner connecting portion 21, so that the whole structure is similar to a general corner member, and in the connected state, the first frame connecting portion 12 and the second frame connecting portion 22 function as a connecting frame 30, so that the two adjacent frames 30 are connected by the screen corner connecting assembly. The first connecting piece 10 and the second connecting piece 20 can also be detached through the first corner connecting portion 11 and the second corner connecting portion 21, and in the application of the frame structure and the interactive flat panel of the display device, the first frame connecting portion 12 and the second frame connecting portion 22 can be detached from the correspondingly connected frame body independently, so that the first connecting piece 10 or the second connecting piece 20 can be detached from the display device independently when the first frame connecting portion 12 or the second frame connecting portion 22 is disconnected from the corresponding frame body in the detached state between the first corner connecting portion 11 and the second corner connecting portion 21.

Because the frame 30 of the display device such as the interactive flat panel is internally provided with the installation space for installing the functional components, in order to ensure that the functional components are stable in the using process of the display device such as the interactive flat panel, the functional components are limited in the installation space of the frame 30, the first corner connecting part 11 or the second corner connecting part 21 is provided with the component limiting part 13, the screen corner connecting component is provided with the screen corner connecting component between any two adjacent frames 30 in the application of the display device such as the interactive flat panel, namely, the two opposite ends of one section of the frame 30 are provided with the screen corner connecting components, the screen corner connecting components are in the assembly state with the frames 30, the component limiting parts 13 are positioned at the end part of the installation space of the frame 30, the component limiting parts 13 positioned on the screen corner connecting components at the two opposite ends of the same frame 30 are respectively and are opposite to the two ends of the installation space, thereby serving to prevent the functional components located in the installation space of the corresponding bezel 30 from moving in the length direction of the bezel 30 or coming off the bezel 30.

A screen corner coupling assembling connects the frame 30 of two adjacent settings respectively, in order to reduce the processing cost and the degree of difficulty, can set a spacing portion 13 of part to the installation space setting in just facing adjacent both sides frame 30 respectively to restrict the one of them one end of the installation space in the frame 30 of two adjacent settings respectively, make full use of the function of structure.

According to the above scheme of the screen corner connecting assembly with the split type arrangement, in this embodiment, the first corner connecting portion 11 is provided with the component limiting portion 13, for example, when the functional components in the frame 30 need to be maintained, overhauled or replaced, only the first frame connecting portion 12 needs to be disconnected from the corresponding frame 30, and then the first corner connecting portion 11 is disconnected from the second corner connecting portion 21, so that the first connecting member 10 can be detached from the frame 30 and the second component alone, in the process of detaching the first connecting member 10 from the frame 30 and the second connecting member 20, the component limiting portion 13 arranged on the first corner connecting portion 11 can be detached from the end portion of the frame 30 along with the first connecting member 10, thereby allowing one end of the installation space in the two adjacent frames 30 to be opened outside the display device, and providing a position for the operator to perform maintenance operation. Compared with the traditional structure comprising the inner corner piece and the outer corner piece, the scheme of the embodiment can complete the connection of the frame 30 and the limit of the functional component without independently processing the inner corner piece and the outer corner piece, and the component limit part 13 can be integrally formed with the first connecting piece 10 or the second connecting piece 20 for production, so that the processing cost is saved, the disassembly and assembly difficulty of the corner piece is reduced, and the maintenance, repair and replacement of the functional component by an operator are facilitated; compare the corner spare structure that traditional integral type set up, the scheme of this embodiment is with the split type setting of first connecting piece 10 and second connecting piece 20, and the operator only needs can accomplish the dismantlement of the spacing portion 13 of part through detaching first connecting piece 10 or second connecting piece 20 to let the holding chamber 31 of corresponding frame 30 open, so that the operator carries out subsequent maintenance work. After the maintenance is finished, the functional parts can be limited again only by installing the detached first connecting piece 10 or the detached second connecting piece 20 back to the original position, so that the steps and the difficulty of disassembling and assembling the screen corner connecting assembly are reduced.

As shown in fig. 4 to 5, as a further specific solution of the screen corner connecting assembly, a first connecting structure is disposed between the first corner connecting portion 11 and the second corner connecting portion 21, and the first connecting structure is configured to connect and fix the first connecting piece 10 and the second connecting piece 20, that is, the first connecting structure can be used to disassemble and assemble the first connecting piece 10 and the second connecting piece 20.

In this embodiment, the first connecting structure is specifically a detachable connecting structure, which realizes the detachable connection between the first connecting piece 10 and the second connecting piece 20, and may be a connecting structure such as a snap connection, a plug connection, a threaded connection, and the like.

In order to ensure that the screen corner connecting assembly has sufficient supporting force on the two side frames 30 which are adjacently arranged in an assembling state, the first connecting structure comprises a first positioning hole 111, a first fixing hole 211 and a first locking piece 212, the first locking piece 212 can be a fastener, a bolt, a screw and other fixing pieces, the first connecting structure in the embodiment adopts a threaded connecting structure, the diameter of the first positioning hole 111 is larger than the diameter of a threaded section of the first locking piece 212 and smaller than the diameter of a screw head of the first locking piece 212, the first fixing hole 211 is configured to be in threaded connection with the first locking piece 212, so that the first locking piece 212 can be fixedly in threaded connection with the first fixing hole 211 through the first positioning hole 111, and a member provided with the first positioning hole 111 is abutted against and pressed against the member provided with the first fixing hole 211 through the screw head.

The first fixing hole 211 is opened in the second corner connecting portion 21 in a state where the first positioning hole 111 is penetratingly provided in the first corner connecting portion 11; when the first fixing hole 211 is opened in the first corner connecting portion 11, the first positioning hole 111 is inserted into the second corner connecting portion 21.

In the present embodiment, the first positioning hole 111 is provided to penetrate the first corner connecting portion 11, and the first fixing hole 211 is provided to the second corner connecting portion 21. In the specific assembling process, the first connecting part 10 is at least partially overlapped at the rear side of the second connecting part 20, the thread section of the first locking part 212 penetrates through the first positioning hole 111 and then is in threaded connection with the first fixing hole 211, the first connecting part 10 is abutted against the second connecting part 20 by the screw head of the first locking part 212, and the installation is completed, otherwise, the first locking part 212 is only required to be detached from the second connecting part 20 during the detachment, and the detachment of the first connecting part 10 can be completed.

The reason why the first connecting member 10 overlaps the rear side of the second connecting member 20 is that the bezel 30 and the screen corner connecting member need to be detached by detaching the rear side of the rear panel, and therefore, such an arrangement structure can expose the first locking member 212 from the rear side of the display device after the display device is detached, which is convenient for detachment.

In order to save the installation space inside the interactive flat plate, the first locking member 212 may be a countersunk screw, and correspondingly, a peripheral portion of one side of the first positioning hole 111 far away from the first fixing hole 211 is provided with a countersunk hole, so that when the first locking member 212 abuts against the first connecting member 10, the screw head of the first locking member will not protrude from the surface of the first connecting member 10.

Further, in order to make the screen corner connecting assembly structurally match with the frame 30 and improve the connection strength between the screen corner connecting assembly and the frame 30, the first connecting member 10 and the second connecting member 20 are strip-shaped structures, the first frame connecting portion 12 extends along a straight line from one end close to the first corner connecting portion 11 to one end away from the first corner connecting portion 11, the second frame connecting portion 22 extends along a straight line from one end close to the second corner connecting portion 21 to one end away from the second corner connecting portion 21, and when the screen corner connecting assembly is assembled on two adjacent frames 30, the first frame connecting portion 12 and the second frame connecting portion 22 are respectively arranged along the extending direction of the corresponding frame 30 and are respectively connected with the corresponding frame 30.

When the first connecting member 10 and the second connecting member 20 are separated, that is, the first corner connecting portion 11 and the second corner connecting portion 21 are separated, and the first frame connecting portion 12 and the second frame connecting portion 22 are separated from the corresponding frame 30, the first connecting member 10 or the second connecting member 20 can move relatively along the length direction thereof to separate from the corresponding frame 30.

As shown in fig. 7, in order to ensure that the first and second connection members 10 and 20 can be accurately connected to each other and the bezel 30 in the assembled state, a positioning guide structure is provided between the first and second corner connection portions 11 and 21, so that the first and second positioning holes 111 and 60 are relatively communicated with each other in a state where the first and second corner connection portions 11 and 21 are connected to each other by the first connection structure, that is, the first and second corner connection portions 11 and 21 are limited to the mounting positions by the positioning guide structure, by limiting the mounting positions and the attaching and detaching directions of the first and second connection members 10 and 20. In a state where the first corner connecting portion 11 and the second corner connecting portion 21 are separated and the first frame connecting portion 12 and the corresponding frame 30 are separated, the positioning guide structure may further guide the moving direction of the first connecting member 10 in which the first connecting member 10 is detached or mounted on the frame 30, so that the first connecting member 10 can move in the length direction of the corresponding frame 30 to be mounted in the frame 30 or detached from the frame 30.

Specifically, the positioning guide structure includes a limiting step 213 and a positioning block 112, and the positioning block 112 can be abutted against the limiting step 213, so that the limiting step 213 limits and guides the moving direction of the positioning block 112.

When the positioning block 112 is provided in the first corner connecting portion 11, the limit step 213 is opened in the second corner connecting portion 21; when the first corner connecting portion 11 has the limit step 213, the positioning block 112 is provided in the second corner connecting portion 21.

In the present embodiment, a positioning block 112 is disposed on the first corner connecting portion 11, and the limiting step 213 is disposed on the second corner connecting portion 21, where the limiting step 213 includes a first step surface 2131, a second step surface 2132, and a third step surface 2133, and the first step surface 2131 and the second step surface 2132 are disposed adjacent to each other at an angle.

In this embodiment, the first connecting member 10 is overlapped on the upper portion of the second connecting member 20, the cross-sectional structure of the first frame connecting portion 12 is matched with the structure of the limiting step 213, and in a state where the first connecting member 10 is overlapped on the upper portion of the second connecting member 20, the first step surface 2131 faces the rear side of the second connecting member 20 and extends to the outer side of the first connecting member 10, and the second step surface 2132 is perpendicular to the first step surface 2131 and faces the outer side surface of the first connecting member 10, so that two limiting surfaces are formed between the first step surface 2131 and the second step surface 2132, and when the first frame connecting portion 12 is engaged with the frame 30, the frame 30 can be engaged with the first step surface 2131 and the second step surface 2132, so that the first connecting member 10 can reciprocate along the length direction of the opening direction of the limiting step 213.

The direction of the third stepped surface 2133 is opposite to the direction of the second stepped surface 2132, and in the process of matching the second connecting member 20 with the corresponding frame 30, the third stepped surface 2133 is used for abutting against the end of the corresponding frame 30 to limit the movement range of the second connecting member 20, and of course, if the limiting step 213 is disposed on the first connecting member 10 and the positioning block 112 is disposed on the second connecting member 20, the third stepped surface 2133 limits the movement range of the first connecting member 10. In this embodiment, when the screen corner connector is engaged with the frame 30, the third step surface 2133 abuts against the end of the frame 30 corresponding to the second connector 20, so as to prevent the second connector 20 from excessively extending into the frame 30 along the length direction during the assembly process, and the first step surface 2131 abuts against the front side of the first connector 10 (the first frame connecting portion 12) and cooperates with the frame 30 to limit the movement range of the second connector 20 in the front-back direction, and the second step surface 2132 abuts against the inner side of the first connector 10 (the first frame connecting portion 12) and cooperates with the third step surface 2133 to display the movement freedom of the second connector 20 in the length direction, so as to achieve the structure that the frame 30, the first connector 10, and the second connector 20 are in spacing engagement with each other, so that the first connector 10 can only move along its own length direction to detach the frame 30 in the detached state, thus, the part limiting part 13 can be separated from the frame 30 along with the first connecting piece 10, so that the installation space of the frame 30 is opened, and an operation and maintenance position is provided.

In the present embodiment, in a state where the first corner connecting portion 11 is connected to the second corner connecting portion 21, the component stopper 13 is located at a lower portion of the stopper step 213, and limits the degree of freedom in the rear direction of the first connecting member 10 in the detached state to a certain extent, so that the first connecting member 10 needs to be inserted into or pulled out of the installation position connected to or separated from the bezel 30 along the longitudinal direction thereof.

In order to improve the assembly space utilization rate between the components, the first connecting structure is disposed between the limit step 213 and the positioning block 112, in the present embodiment, the first positioning hole 111 is opened at the first corner connecting portion 11, and the first fixing hole 211 is opened at the second corner connecting portion 21.
