Its structure includes the main frame and the adjustment mechanism, and each part has a specific function. The main frame is composed of main columns and beams. The adjustment mechanism includes adjustment bolts and fixing buckles. The heat dissipation structure is designed with heat sinks or holes. The stability and precise adjustment of this type of bracket are crucial to the display effect and long-term operation. Therefore, when selecting and installing, it is necessary to take into account functionality, aesthetics and practicality to ensure the best overall system effect.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-5 , the utility model provides an embodiment: a wall-mounted mounting bracket for a liquid crystal splicing screen, comprising a right hollow column 1 and a left hollow column 2 arranged on one side of the right hollow column 1, both ends of the surfaces of the right hollow column 1 and the left hollow column 2 are welded with C-mouth sheet metal seats 3, an upper wall-mounted beam 4 and a lower wall-mounted beam 5 are respectively installed between the two C-mouth sheet metal seats 3 in the same X-axis direction, and the surfaces of the upper wall-mounted beam 4 and the lower wall-mounted beam 5 are both provided with through holes 6 for bolting the liquid crystal splicing screen, and a multi-point circular plug-in structure 7 for splicing the two mounting brackets in the vertical direction is provided on the outer wall of the side where the upper wall-mounted beam 4 and the lower wall-mounted beam 5 are away from each other, and a first rear support plate 8 and a second rear support plate 9 are respectively installed at both ends of the back side of the right hollow column 1 and the left hollow column 2, and a semi-column plug-in structure for splicing the two brackets in the horizontal direction is installed inside the first rear support plate 8 and the second rear support plate 9;

[0020] A solid steel column 13 is fixed to the bottom ends of the right hollow column 1 and the left hollow column 2. The outer diameter of the solid steel column 13 is equal to the inner diameter of the right hollow column 1 and the left hollow column 2.

[0021] The right hollow column 1 and the left hollow column 2 between the upper wall-mounted beam 4 and the lower wall-mounted beam 5 are provided with a central wall-mounted beam installed on their surfaces. The right hollow column 1, the left hollow column 2, the upper wall-mounted beam 4, the lower wall-mounted beam 5 and the central wall-mounted beam form a "sun"-shaped structure. By forming the bracket structure into a "sun"-shaped structure, the bracket is better supported and balanced in both horizontal and vertical directions, that is, the various components in the "sun"-shaped structure are intertwined to form more connection points and connection surfaces. This structure can effectively share the weight and pressure of the LCD splicing screen;

[0022] The semi-column plug-in structure includes a main semi-cylinder 10 and a secondary semi-cylinder 11 fixed inside the first rear support plate 8 and the second rear support plate 9. The length of the main semi-cylinder 10 is longer than that of the secondary semi-cylinder 11. The main semi-cylinder 10 and the secondary semi-cylinder 11 are plugged together to form a columnar structure. A plane wall 12 is provided on the outer wall of the main semi-cylinder 10 and the secondary semi-cylinder 11 on the side away from each other. A circular hole 1201 for the bolt to pass through is opened through the plane wall 12. When the two brackets are connected in the horizontal direction, the first rear support plate 8 and the second rear support plate 9 are in a relative state, and the main semi-cylinder 10 and the secondary semi-cylinder 11 are concentrically connected to form a complete columnar structure until the two are plugged to the limit state;

[0023] The staff takes out the bolts and passes them through the circular holes 1201 of the main semi-cylinder 10 and the auxiliary semi-cylinder 11. The circular holes 1201 are used for the installation of bolts and nuts. The two right hollow columns 1 are not easily loosened or fallen off due to external interference after connection, thus ensuring the stability of the overall system of the LCD splicing screen;

[0024] The multi-point circular plug-in structure 7 includes a plurality of circular frames 701 welded to the bottom end of the lower wall-mounted beam 5, and a plurality of rectangular cut-out grooves 702 opened at the top and bottom ends of the upper wall-mounted beam 4. The rectangular cut-out grooves 702 are used for the circular frames 701 to pass through. When two brackets are connected in the vertical direction, the solid steel column 13 is inserted into the inside of the right hollow column 1 and the left hollow column 2. At the same time, the circular frame 701 passes through the rectangular cut-out grooves 702 to the outside of the upper wall-mounted beam 4 until the upper wall-mounted beam 4 and the lower wall-mounted beam 5 are in contact with each other, so that the brackets are connected in the vertical direction, and the brackets are spliced ​​horizontally and vertically, so that the LCD splicing screen can be assembled in the horizontal and vertical directions according to actual needs, meeting the needs of expansion and installation of the splicing screen;

[0025] When the splicing screen is installed on the wall-mounted wall composed of the bracket, the LCD splicing screens can be installed seamlessly, so that there is no obvious gap or gap between the modules of the LCD splicing screen, presenting a more unified and perfect visual effect.

[0026] When the embodiment of the present application is used, firstly, a single bracket structure is formed by the right hollow column 1, the left hollow column 2, the upper wall-mounted beam 4 and the lower wall-mounted beam 5, and the through holes 6 preset on the surfaces of the upper wall-mounted beam 4 and the lower wall-mounted beam 5 are bolted to the back panel of the liquid crystal splicing screen, so that the liquid crystal splicing screen is connected to the mounting bracket. When the staff needs to vertically and horizontally splice the mounting bracket to assemble a wall-mounted wall for multiple liquid crystal splicing screens to be installed, the staff takes out multiple brackets so that the two adjacent brackets in the horizontal direction are connected by half columns. The plug-in structure is connected, and the half-column plug-in structure is positioned by bolts. Between two adjacent brackets in the vertical direction, the upper wall-mounted beam 4 and the lower wall-mounted beam 5 are connected by a multi-point circular plug-in structure 7. Compared with the bolted structure between the connecting blocks, the adjacent brackets are connected by half-column plug-in and multi-point circular plug-in structure 7. There are more connection points between adjacent brackets, which can more evenly share the overall weight and pressure of the LCD splicing screen, reduce the pressure concentration problem caused by single-point force, and make the bracket structure and the splicing screen as a whole more solid and stable.
