[0002] The diameter of the circular display screens produced on the market exceeds 1.5 meters. The unit panels are fixed with screws. Due to the wide box, the weight of the product increases, the overall proportion of the display screen and the lamp pole is not coordinated, the multi-layer splicing strength of the display screen box is not enough and it is not conducive to installation and debugging at the construction site.

[0003] The utility model adopts a multi-prism integrated main frame, the overall diameter of which can be less than 0.5 meters. It has high strength and a shape that matches the overall lamp pole. It adopts an ultra-narrow unit board and can be installed by magnetic suction. It is easy to install and disassemble, reduces the difficulty of maintenance, and has lower costs.

[0004] The utility model has beautiful appearance, lower cost and wider market application. Utility Model Content

[0005] In order to reduce the volume and weight of a display screen while ensuring aesthetics, and at the same time reduce the difficulty of installation and maintenance, improve the strength of a display screen bracket, and reduce production costs, the utility model provides a multi-prism display screen.

[0006] The technical solution adopted by the utility model to solve the technical problem is: a multi-prism display screen, comprising:

[0007] Polygonal main support: It is composed of a top plate, a bottom plate and multiple support plates;

[0008] The support plate is provided with heat dissipation holes for heat dissipation and for passing the wires of electronic components and / or installation holes for installing electronic components;

[0009] A plurality of fixed bridges for reinforcing the polygonal column main support and carrying electronic components are radially installed inside the polygonal column main support; an electrical carrier board for mounting electronic components is installed on the fixed bridge;

[0010] Display screen: It is surrounded by display screen unit panels installed on the outside of the bracket panel.

[0011] In the utility model, the electrical components can be installed on the electrical carrier to form an electrical unit, and then the electrical unit is installed on the fixed bridge inside the polyhedral main bracket, which can effectively prevent external water vapor from entering the electrical cavity, protect the internal electronic components, and also facilitate the inspection and replacement of the electrical components. The radial installation of the fixed bridge can further enhance the structural stability of the entire polyhedral main bracket and prevent deformation due to external forces.

[0012] As a further improvement of the utility model, the bracket plate is made of magnetic material, and the display unit plate is installed on the outer side of the bracket plate using a magnetic structure. This solution uses a magnetic structure to install the display unit plate, which is convenient for the unit plate to be disassembled and can also significantly reduce the maintenance cost of the entire display screen. When the corresponding unit plate is damaged, it only needs to be directly removed and replaced or repaired.

[0013] Specifically, the combination of the display unit board and the bracket board can be in accordance with the following specific scheme: the back of the display unit board is installed with a positioning pin and a magnetic column, the bracket board is provided with a pin hole matching the positioning pin, the display unit board can be inserted into the pin hole through the positioning pin, and is adsorbed on the bracket board through the magnetic column to complete positioning and installation, and there is a gap h between the installed display unit board and the bracket board, h≥0.5cm. The function of the gap is mainly to facilitate the dissipation of heat generated by internal electrical components, and it can also facilitate the setting of rain shields and facilitate the discharge of rainwater.

[0014] As a further improvement of the utility model, a rain shield is provided in the outer side of the polygonal main bracket to prevent rainwater from entering the interior of the polygonal main bracket. The rain shield can be fixed above the mounting hole by welding or other methods, which can effectively prevent rainwater from flowing into the interior of the main bracket along the bracket plate in rainy weather, causing the electrical components to get damp.

[0015] As a further improvement of the present invention, LED lamp beads are integrated on the outer surface of the display unit board to realize the display screen image display.

[0016] As a further improvement of the utility model, the electronic components include a component cooling fan, a speaker, a power supply, a receiving card, a power amplifier board, and a control card. In addition, the user can also add other electrical components according to specific needs.

[0017] As a further improvement of the present invention, a drainage hole is provided at the lower portion of the polygonal column main support for draining rainwater inside the main support.

[0018] As a further improvement of the present invention, a main cooling fan is installed inside the polyhedral main bracket near the top plate. For example, a turbine cooling fan can be installed to help dissipate heat from electrical components inside the main bracket, thereby improving the heat dissipation capacity of the device.

[0019] As a further improvement of the present invention, the polygonal main bracket is a 16-prism body. In this case, the polygonal main bracket can be enclosed by 16 integrally formed bracket plates, and the corresponding display screen can be enclosed by 16 large-area display screen unit plates. However, in order to facilitate maintenance and production, the 16 large-area display screen unit plates can also be split into 80 small-area display screen unit plates (see the specific implementation). It is easy for those skilled in the art to understand that the polygonal main bracket can also adopt 8 prisms, 15 prisms, 17 prisms, etc., and the principle is the same as that of the present invention.

[0020] The beneficial effects of the utility model are as follows: 1) The multi-prism main bracket of the utility model has high strength, the unit board splicing gap is small, and the volume and weight of the display screen are significantly reduced, which effectively solves the problems of the existing technology using thick frame unit boards, which are unsightly and inconsistent with the lamp pole, and poor display effect. 2) The utility model has the advantages of beautiful shape, good imaging effect, convenient maintenance, low production cost, etc., and has a wide range of application space, especially suitable for the decoration of landscape lamp poles.
