Description

Technical Field

[0001] This application belongs to the technical field of traffic warning equipment, and in particular relates to an LED display screen for road traffic. Background Technology

[0002] LED displays are widely used in squares, outdoors, and on building exteriors. They are used to display various information such as text, images, and videos by controlling semiconductor light-emitting diodes, thereby achieving the purpose of displaying advertisements and promotional images to people.

[0003] In road traffic, to ensure that drivers and pedestrians approaching from different directions can see the information on the screen, double-sided displays are generally used to display information. However, the existing double-sided displays are mostly installed by holding two single-sided screens to the column. Since they are installed relative to each other, the installation is difficult and maintenance is troublesome. Summary of the Invention

The support rod is used to support and fix the main housing. The door panel is hinged to both sides of the main housing. One end of the telescopic rod is hinged to the main housing, and the other end is hinged to the door panel. The display screen is located on the side of the door panel away from the main housing. The support rod is connected to the main housing through a flange, and the wires in the support rod pass through the flange and are connected to the main housing.

[0007] Optionally, a gas spring is provided between the main housing and the door panel, the gas spring being used to drive the door panel to move and support the door panel.

[0008] Optionally, the top of the door panel is hinged to the main body, and the bottom of the door panel is snapped into the main body via a buckle.

[0009] Optionally, sealing rubber gaskets are provided on the opposite surfaces of the main body and the door panel.

[0010] Optionally, the display screen is equipped with a cooling fan.

[0011] Optionally, the display screen is provided with a positioning mounting hole, a pin is inserted into the mounting positioning hole, and the pin passes through the positioning hole and is threadedly connected to the door panel.

[0012] Optionally, the heat dissipation holes on the main housing are opposite to the cooling fan.

[0013] Optionally, a mounting base is provided at the bottom end of the support rod, and a reinforcing rib is provided between the mounting base and the support rod.

[0014] Compared with the prior art, this application has at least the following beneficial effects:

[0015] This application connects the main cabinet to the support rod, and then the side panels are hinged to the main cabinet, allowing for easy opening of the side panels to inspect and maintain the wiring inside the main cabinet. The main cabinet and the support rod are connected by flanges, allowing the wires in the support rod to pass through the flanges and connect to the wiring inside the main cabinet, preventing exposed wires and ensuring the aesthetics and structural stability of the display screen. A gas spring is installed between the main cabinet and the door panels, allowing the door panels to be opened slowly with the help of the gas spring, providing good structural stability and support for the display screen.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0022] Example 1

[0023] like Figure 1 and Figure 2As shown, an LED display screen 5 for road traffic includes a support rod 1, a main housing 2, a door panel 3, a telescopic rod 4, and a display screen 5. The support rod 1 is used to support and fix the main housing 2. The door panel 3 is hinged to both sides of the main housing 2. One end of the telescopic rod 4 is hinged to the main housing 2, and the other end is hinged to the door panel 3. The display screen 5 is set on the side of the door panel 3 away from the main housing 2. The support rod 1 and the main housing 2 are connected by a flange. The wires in the support rod 1 pass through the flange and are connected to the main housing 2.

[0024] This application has displays 5 on both sides to ensure that drivers and pedestrians approaching from different directions can see the information on the screens; the door panels 3 are hinged to the main body 2, which can be easily opened to inspect the wiring inside the main body 2; the main body 2 and the support rod 1 are connected by a flange, and the wires in the support rod 1 can pass through the flange to connect to the wiring inside the main body 2, avoiding exposed wires and making it more aesthetically pleasing.

[0025] Example 2

[0026] The difference between this embodiment and Embodiment 1 is that, as Figure 1 and Figure 2 A gas spring 6 is installed between the main body 2 and the door panel 3. The gas spring 6 is used to drive the door panel 3 to move and support the door panel 3. With the gas spring 6 installed between the main body 2 and the door panel 3, the door panel 3 can be opened slowly with the help of the gas spring 6. The structure has good stability and high safety. When the door panel 3 is opened, it can also support the display screen 5.

[0027] In this embodiment, the top of the door panel 3 is hinged to the main body 2, and the bottom of the door panel 3 is latched to the main body 2. The door panel 3 can be opened by opening the latch and rotating it along the hinge point using a gas spring 6 or a telescopic rod 4.

[0028] To ensure the airtightness between the main body 2 and the door panel 3, sealing rubber gaskets 7 are provided on the opposite surfaces of the main body 2 and the door panel 3. The sealing is achieved by the elastic deformation of the rubber gaskets 7.

[0029] The display screen 5 is equipped with a cooling fan, and the heat dissipation holes on the main body 2 are opposite to the cooling fan, thereby accelerating the heat dissipation from the main body 2.

[0030] In this application, the connection between the display screen 5 and the door panel 3 is as follows: the display screen 5 is provided with positioning mounting holes, and a pin is inserted into the positioning holes. The pin passes through the positioning holes and is threadedly connected to the door panel 3. Compared with traditional screens, it has good area extensibility and seamless splicing, thus ensuring the display effect of the image. Compared with traditional embedded installation, due to the tolerance of sheet metal bending, it is difficult to control the size of the module gap, and the display screen 5 module is prone to compression and unevenness.

[0031] The bottom end of the support rod 1 is provided with a mounting base 8, and the support rod 1 is installed on the ground through the mounting base 8. A reinforcing rib 9 is provided between the mounting base 8 and the support rod 1.

[0032] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
