As shown in fig. 1 to 10, a screen support provided by an embodiment of the present invention includes: a base 100, a stand body 200, an adapter plate 300 for mounting a screen 400; the base 100 comprises a vertical beam 101 which is used for being fixedly connected with an embedded part 700 and can cross the embedded part 700 along the vertical direction, the support main body 200 is fixedly connected with the vertical beam 101, and the adapter plate 300 is fixedly connected with the support main body 200.

For convenience of installation, the base 100, the bracket body 200 and the adapter plate 300 are three separate structures, and the base 100, the bracket body 200 and the adapter plate 300 need to be installed one by one.

The adapter plate 300 is used to mount the screen 400, and for convenience of mounting and dismounting, the adapter plate 300 is preferably selected to fix the screen 400 by the screen mounting bolt 600.

The length of the vertical beam 101 is set according to actual needs, for example, the length of the vertical beam 101 is 1000mm, or the length of the vertical beam 101 is slightly larger than 1000mm, or the length of the vertical beam 101 is slightly smaller than 1000mm. This embodiment is not limited to this. Preferably, the vertical beam 101 has: a vertical beam top section that can extend out of the top side of the embedment 700, and/or a vertical beam bottom section that can extend out of the bottom side of the embedment 700. In order to enhance the function of the vertical beam 101, it is preferable that the vertical beam 101 has the vertical beam top section and the vertical beam bottom section.

The specific structure of the vertical beam 101 is selected according to actual needs, for example, the vertical beam 101 is a hollow structure, or the vertical beam 101 is a solid structure. This embodiment does not limit this.

In the screen bracket provided by the embodiment of the invention, the vertical beams 101 are used for being fixedly connected with the embedded parts 700 and can cross the embedded parts 700 in the vertical direction, compared with the pre-embedding of the embedded parts 700, the installation of the vertical beams 101 is easier to ensure the accuracy in the vertical direction, namely, the vertical beams 101 distributed in the horizontal direction are easier to ensure to be at the same height, and the bracket main body 200 is installed on the vertical beams 101, so that the vertical beams 101 can make up the defect of uneven height of the embedded parts 700, the bracket main bodies 200 can be ensured to be all installed at the same height, namely, the screen 400 can be ensured to be installed at the same height, and the influence of the height difference between the embedded parts 700 distributed in the horizontal direction on the height of the screen 400 is reduced; meanwhile, the requirement on the pre-embedding precision of the embedded part 700 is reduced, the civil engineering requirement is reduced, and meanwhile, the installation precision is ensured to meet the design requirement.

Meanwhile, the screen 400 is installed behind the screen support, so that the screen support is not exposed, and the attractiveness is improved.

In the screen support, there may be one or more vertical beams 101. In order to improve stability and shock resistance, the vertical beams 101 are at least two and are distributed side by side. Specifically, all the vertical beams 101 are sequentially distributed along the length direction of the embedded part 700, that is, all the vertical beams 101 are sequentially distributed along the horizontal direction. For example, there are three vertical beams 101, i.e., three vertical beams 101 per screen support.

In order to ensure that the screens 400 are installed at the same height, in the screen support, the base 100 further includes a hanging substrate 102 fixedly connected to the vertical beam 101, the hanging substrate 102 is perpendicular to the vertical beam 101, and the hanging substrate 102 extends along the width direction of the vertical beam 101; wherein, the bracket main body 200 is fixedly connected with the vertical beam 101 through the hanging substrate 102.

It is understood that the mounting base 102 and the embedment 700 are parallel or substantially parallel. For example, the hanging substrate 102 and the embedded part 700 both extend along a horizontal direction, i.e., the length direction of the hanging substrate 102 is the length direction of the embedded part 700. The thickness direction of the hanging substrate 102 is the same as the thickness direction of the vertical beam 101. The vertical beams 101 are perpendicular to each other in the width direction, thickness direction, and length direction. The hanging substrate 102 is perpendicular to each other in the width direction, thickness direction and length direction.

In the screen holder, the hanging substrate 102 and the vertical beam 101 are two separate members. In the actual installation process, the position of the hanging substrate 102 on the vertical beam 101 can be adjusted according to the size of the screen 400, that is, the height of the hanging substrate 102 is adjusted, so that the height of the screen 400 from the ground can be adjusted, the requirements of screens 400 with different sizes can be met, and the screen 400 can be freely upgraded.

It should be noted that the height of the hanging substrate 102 can be adjusted according to the protruding tolerance of the embedded part 700 and the height of the decorative plate. The decorative plate is a plate decorated on the wall surface after the base 100 is installed.

In order to satisfy strength and shock resistance, the hanging base plate 102 is fixedly connected to the vertical beam 101 by welding. Of course, the hanging substrate 102 and the vertical beam 101 may be detachably fixed and connected, and are not limited to the above embodiment.

One or more than two hanging substrates 102 may be provided. In order to improve stability and shock resistance, at least two hanging substrates 102 are provided, and are sequentially distributed along the length direction of the vertical beam 101. It is understood that each of the hanger base plates 102 is fixedly coupled to the bracket body 200.

When there are at least two vertical beams 101, all the vertical beams 101 are fixedly connected to each hanging substrate 102, that is, each hanging substrate 102 spans all the vertical beams 101 in the horizontal direction.
