Detailed Description

The invention will be further elucidated and described with reference to the following embodiments and drawings in which:

referring to fig. 1 to 3, an LED display panel includes a main body 10, a base 20, a hinge 30, a movable frame 40, a first LED display module 51 and a second LED display module 52.

The main body 10 is provided therein with a main board 11 and a power source 12 electrically connected to each other, the main body 10 is fixed to the base 20, and a movable frame 40 of the main body 10 is rotatably connected by a hinge 30. The present embodiment employs a lateral rotation connection of the main body 10 and the movable frame 40. And the maintenance of users is convenient. The necessary jacking structure for opening and closing up and down is eliminated, and the cost is saved.

The first LED display module 51 is embedded in the side wall of the main body 10, the second LED display module 52 is embedded in an end surface of the movable frame 40 away from the first LED display module 51, and both the first LED display module 51 and the second LED display module 52 are electrically connected to the main board.

A plurality of horizontally arranged main ventilation pipes 61 are arranged inside the main body 10, two ends of each main ventilation pipe 61 penetrate through two opposite side walls of the main body 10, and the main ventilation pipes 61 are attached to the back of the first LED display module 51.

A plurality of horizontally arranged main ventilation pipes 61 are arranged inside the main body 10, two ends of each main ventilation pipe 61 penetrate through two opposite side walls of the main body 10, and the main ventilation pipes 61 are attached to the back of the first LED display module 51. When the first LED display module 51 generates a large amount of heat inside the main body 10, the heat is transferred to the side wall of the main ventilation pipe 61, and the main ventilation pipe 61 penetrates through the main body 10, so that natural wind flows in the main ventilation pipe, and the heat is rapidly taken away by the flowing natural wind, so that the heat inside the main body 10 is rapidly released.

A lock catch 13 is arranged on one side wall of the main body 10 away from the hinge 30, a lock hole 41 is arranged on one side wall of the movable frame body 40 away from the hinge 30, and the lock catch 13 is clamped into the lock hole 41 to be fixedly connected.

Similarly, a main ventilation pipe 61 arranged horizontally is arranged inside the movable frame 40, two ends of the main ventilation pipe 61 penetrate through two opposite side walls of the movable frame 40, and the main ventilation pipe 61 is attached to the back of the second LED display module 52. The first LED display module 51 and the second LED display module 52 can be rapidly cooled.

The inside of the main body 10 and the inside of the movable frame 40 are both provided with auxiliary ventilation pipes 62 which are vertically arranged, and the auxiliary ventilation pipes 62 sequentially penetrate through the top of the main ventilation pipe 61 and the top of the main body 10. When the internal temperature rises too fast, the natural wind flowing in the horizontal direction cannot take away the internal heat in a short time. By utilizing the rising principle of hot air, the vertical upward auxiliary ventilation pipe 62 is arranged for the hot air, so that the hot air is naturally diffused upwards, and the heat dissipation is assisted.

The first LED display module 51 and the second LED display module 52 both comprise baffle plates 71 and LED lamp beads 72 which are arranged in an array, and the baffle plates 71 and the LED lamp beads 72 are arranged at intervals in the horizontal direction. The phenomenon of blurred pictures caused by mutual interference between the LED lamp beads 72 is avoided.

The bottom of the base 20 is provided with universal wheels 21, so that the LED display screen can be conveniently moved by workers.

The utility model provides a LED display screen is equipped with the main ventilation pipe 61 that many levels were arranged inside main part 10, and two relative lateral walls of main part 10 are run through at main ventilation pipe 61 both ends, and main ventilation pipe 61 pastes and applies in the first LED display module assembly 51 back. When the first LED display module 51 generates a large amount of heat inside the main body 10, the heat is transferred to the side wall of the main ventilation pipe 61, and the main ventilation pipe 61 penetrates through the main body 10, so that natural wind flows in the main ventilation pipe, and the heat is rapidly taken away by the flowing natural wind, so that the heat inside the main body 10 is rapidly released.

It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
