Description

Technical Field

[0001] The utility model belongs to the technical field of LED display equipment, and more specifically, relates to an automatically opening and closing LED display equipment. Background Art

[0002] A retractable screen is a new type of display method, similar to a sliding screen. It can display content independently on two LED screens, or the two LED screens can be combined into a single large screen by sliding. This allows for more and larger displays than a sliding screen. Its novel presentation format can be combined with a background wall to display current content, carrying a huge amount of information. It is widely used in venues such as science and technology exhibition halls, planning exhibition halls, and high-end museum exhibition halls.

[0003] The current retractable screen is relatively large in size, so daily cleaning and maintenance are more troublesome. Workers are required to work at height, which poses certain safety hazards and consumes manpower, making it inconvenient to clean and maintain the retractable screen.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an automatically opening and closing LED display device is provided to achieve a purpose with greater practical value. Utility Model Content

[0007] Furthermore, a receiving groove is provided on the other side of the interior of the cleaning box, a hose is provided inside the receiving groove, and one end of the hose is connected to the connecting pipe.

[0008] Furthermore, one side of the cleaning box is connected to a water tank, a water pump is installed inside the water tank, and the output end of the water pump is connected to a hose.

[0009] Furthermore, a forward and reverse threaded screw rod is horizontally installed inside the slide groove at the upper end of the mounting frame, and the forward and reverse threaded ends of the forward and reverse threaded screw rod respectively pass through the left and right sides of a pair of sliders and are threadedly connected to the pair of sliders.

[0010] Furthermore, a motor 1 is installed on one side of the mounting frame, and an output end of the motor 1 is transmission-connected to a forward and reverse threaded screw through a coupling.

[0011] Furthermore, a screw rod 2 is vertically installed inside the second slide groove, and the screw rod 2 passes through the upper and lower ends of the second slider and is threadedly connected to the second slider.

[0012] Furthermore, a second motor is installed on one side of the top end of the cleaning box, and the output end of the second motor is transmission-connected to the second screw rod through a coupling.

[0013] Furthermore, a controller is installed in the middle position of one side of the cleaning box, and a cleaning door is installed at the bottom end of one side of the cleaning box through a hinge.

[0014] Furthermore, a water inlet is provided at the top of the water tank, and a sealing cover is threadedly connected to the top of the water inlet.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The automatic opening and closing LED display device of the utility model can drive the connecting plate and the connecting seat to move up and down quickly by cooperating with the motor 2, the screw 2 and the slider 2 in the cleaning box. The downward movement of the connecting seat allows the cleaning liquid in the water tank to be transported to the water pipe and the connecting pipe through the water pump in the water tank, and then sprayed onto the surface of the LED display through the nozzle. At the same time, the downward movement of the connecting rod drives the cleaning soft sleeve on one side to wipe the surface of the LED display. The surface of the LED display can be cleaned and maintained automatically and quickly, which greatly reduces manpower and avoids the situation where cleaning personnel have to climb to work and cause safety hazards.

[0017] The automatically opening and closing LED display device of the present invention, through the cooperation of a motor and a forward and reverse threaded screw rod, facilitates driving a pair of sliders in a slide groove above the installation frame to move synchronously in relative directions, and then cooperates with a pair of sliders in a slide groove below the installation frame to drive a pair of LED display screens to move in relative directions, thereby realizing the automatic opening and closing of the two LED display screens, greatly improving the convenience of use.
