Wherein, four angles of second backup pad 21 are provided with adjusting part 4 respectively, can adjust four angles of display screen respectively to adjust the regulation of an angle can be realized to two arbitrary angles of independent regulation. For example, when the adjustment assemblies for adjusting the two upper corners of the second support plate 21 are adjusted independently, and the adjustment direction is to increase the distance between the second support frame 22 and the second support plate 21, the two lower adjustment assemblies 4 are not adjusted, and the second support frame 22 of the display screen forms a downward-inclined angle.

The surface formed by four-point adjustment is difficult to be on the same plane, so that the adjustment of installation personnel is relatively laborious before, mainly depending on experience, the display screen bracket in the prior art mostly adopts two-point adjustment or three-point adjustment from left to right, but the two-point adjustment from left to right can only adjust the height of the left side and the right side of the display screen (the distance from the display screen to the wall), the pitching angle of the display screen cannot be adjusted, and the adjustment mode has extremely high requirements on the installation wall surface, generally needs to carry out special treatment on the wall surface before the installation of the spliced screen bracket, and the wood sandwich plate wall is installed on the wall surface, so the construction period is long, the engineering quantity is large, and the cost; the three-point adjustment mode is more convenient, but the three-point adjustment support is not firm enough in structure and is fragile.

Consequently the concatenation screen support of this application still insists on the form that has adopted four point regulation, an angle through two liang of adjustment subassembly 4 adjustment display screens, keep original left and right sides parallel to each other, the relation that the limit parallel to each other is unchangeable from top to bottom, but through the different limit of nimble adjustment, the horizontal rotation and the pitching about the screen have been produced, make the four points that the single-point regulation appears very easily not appear at same planar situation, the angle of display screen is transferred controllably well, the roughness whole requirement to the installation wall is lower, the wall does not need special treatment under most of the circumstances, later stage installation cost reduces, installation and debugging time limit can shorten by a wide margin, very big saving installation cost.

In the prior art, in the installation process of the splicing screen, the splicing unit needs to be popped out from the front side, and is locked after being debugged, so that the method belongs to 'blind tuning', and because the comparison screen is locked, the comparison screen cannot be directly compared with the adjusted comparison screen for reference, guessed blind tuning can be carried out only according to the horizontal height and pitch difference when the splicing screen is in a locked state at the same time, and repeated adjustment is time-consuming and labor-consuming. When the bracket is in a locked state, the blind adjustment is changed into the bright adjustment through the matching adjustment of the adjuster and the adjusting component 4, and the two are adjusted synchronously; therefore, the original relation that the left side and the right side are parallel to each other and the upper side and the lower side are parallel to each other can be kept unchanged, different sides are adjusted simultaneously, and pitching fine adjustment in the vertical direction of the display screen is adjusted, so that the situation that four points which are easy to appear in single-point adjustment are not on the same plane is avoided.

In this embodiment, the adjusting insertion hole 455 is a hexagonal inner hole, and can be manually adjusted by using a hexagonal wrench, wherein the specific shape and structure of the adjusting insertion hole 455 are not limited by the embodiment of the present application, and may be a pentagonal inner hole, a triangular hole, a splined hole, or the like in an actual production process.
