[0003] An LED display screen is a flat panel display composed of LED modules, used to display various information such as text, images, videos, and recorded signals, providing numerous conveniences for people's daily lives. With the widespread application of LED displays and the continuous improvement of people's demands, the structure and function of display screen products are gradually becoming more diversified. The application of outdoor LED displays is also becoming increasingly widespread, leading to higher requirements for the versatility, installation, and daily maintenance of the displays.

[0004] LED displays on highway signs provide dynamic information to pedestrians and drivers, enhancing the smart highway system. Waterproofing is essential for existing sign displays; furthermore, ease of on-site maintenance is crucial, with rapid repairs and maintenance to minimize road closures being a key design consideration. However, most existing displays rely on rear-opening maintenance, resulting in prolonged high-altitude work and significant traffic disruption. Furthermore, interference from fixed structures like pillars or beams behind the displays further complicates maintenance operations. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an LED enclosure for easy-to-open maintenance of signs. It achieves waterproofing at low cost, allows for maintenance and inspection from the front, has short repair time, low construction costs, and minimal impact on road traffic.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] An LED enclosure for easy opening and maintenance of signboards, the LED enclosure includes a front shell and a bottom shell, the bottom of the front shell and the bottom shell are connected by a hinge, and the top of the front shell and the bottom shell are fastened by hexagonal screws;

[0008] The hinge is a separable hinge pair, which enables the separation of the front shell and the bottom shell.

[0009] The front shell and the bottom shell are fastened together by hexagon socket screws. The front shell has a front vertical edge that is welded to the front shell and has a first through hole. The bottom shell has a rear vertical edge that is welded to the bottom shell and has a threaded hole. The first through hole on the front vertical edge corresponds to the threaded hole on the rear vertical edge. The hexagon socket screw passes through the first through hole and is screwed into the threaded hole to achieve a fast connection between the front shell and the bottom shell.

[0010] Furthermore, an LED module is fixed to the front end of the front shell, and LED lights are installed on the LED module.

[0011] Furthermore, an outer cover is provided on the outside of the LED cabinet. The outer cover is shaped like a door, and the back of the outer cover is fastened to the back of the base shell by countersunk screws.

[0012] Furthermore, the outer cover is equipped with a rain rim, which is used to cover the front shell, bottom shell and LED lights. The rain rim has a certain slope, sloping forward, so that rainwater can flow from the front.

[0013] Furthermore, sealing gaskets are provided around the front and bottom shells.

[0014] Furthermore, a cable connector is provided at the rear end of the bottom shell, from which the cables of the LED cabinet are led out.

[0015] Furthermore, the rear end of the bottom shell is provided with multiple blind hole nuts, which correspond one-to-one with multiple second through holes on the sign.

[0016] Compared with the prior art, the LED enclosure for easy opening and maintenance of signs provided by this utility model has the following advantages:

[0017] (1) The front and bottom shells are connected by a separable hinge pair, allowing the front and bottom shells to be easily opened and closed, facilitating the maintenance or replacement of the internal LED modules. When maintenance is required, the maintenance personnel only need to loosen the hexagonal screws connecting the front and bottom shells to rotate the front shell around the hinge and open it. There is no need for high-altitude work or disassembly of the entire enclosure, which greatly improves maintenance efficiency and reduces construction difficulty and cost. At the same time, since the maintenance operation is carried out in front of the sign, there are no columns or beams to block or interfere with it, making the maintenance process more convenient and safe.

[0018] (2) The combination of sealing gaskets and outer cover greatly improves the outdoor sealing and rainproof effect of LED cabinet. The sealing gasket effectively prevents rainwater from seeping in from all sides of the cabinet, while the rain cover design can block most of the rainwater. Even if a small amount of rainwater splashes onto the rain cover, it will flow smoothly down from the top of the front shell due to the slope design of the rain cover, avoiding damage to the inside of the cabinet.

[0019] (3) The cable connector and blind hole nut set at the rear end of the bottom shell facilitate the cable lead-out and the fixing of the box, and improve the convenience and stability of installation. Attached Figure Description
