On this basis, 4 upper surfaces of the rain eave type protective structures can also be provided with a plurality of water drainage grooves, and the water drainage grooves are arranged, namely, water drainage channels are arranged, so that rainwater can be drained away quickly along the groove orientation.

On the basis of the above embodiment, the peripheries of the first operation opening and the second operation opening are respectively provided with a water guide groove 5. The falling rainwater is drained by the water guide grooves 5 and flows away from the grooves to two sides. The water guide groove 5 is preferably formed integrally with the operation opening 1, so that no leakage gap can be ensured, the groove section of the water guide groove 5 can be in the shape of a semicircle, an open rectangle or the like, and specific limitation is not required as long as the water guide function is met.

Considering that the amount of falling water is large when the rain speed is large, and the water can overflow due to the fact that the instantaneous water amount of the groove is increased, one side of the water guide groove 5 above the operation door 2 is designed to be a bevel edge with a certain inclination angle, and the water drainage speed is increased more favorably.

The four sides of the operation opening 1 of the two back doors are provided with the integrated water guide grooves 5, so that the operation opening 1 can be ensured not to store water and leak water after the operation door 2 is closed, and accumulated water leaking into a door gap can be effectively guided.

On the basis, a foaming rubber ring can be arranged at the joint of the operation door 2 and the water guide groove 5. If rain eaves type protective structure 4 is inside infiltration, can play effectively and stop the effect, make the lock can hinge tightly simultaneously, increase the box leakproofness. The foamed rubber ring can adopt the existing sticky foamed rubber ring. For example, the sponge foaming silica gel strip is suitable for work such as sealing of matched electric appliances, electronics, furniture equipment, toys, hardware, medical equipment, sports goods, sound equipment, lamp decoration, machinery, cars, bottles and cans, sealing of building curtain walls and the like. The product is used for a sealing ring bonded on a display screen, and the silicone rubber strip has excellent ozone resistance, solvent resistance and electrical insulation, and is a product of a sealing element for chemical engineering, medicine, food, electronics and mechanical work.

On the other hand, because the equipment belongs to low-power consumption products, self calorific capacity is little, and the heat of inside production is less, can also increase heat radiation structure on the box. For example, one way is to provide a breathing hole in the bottom of the case for dissipating heat. In another mode, a water leakage hole at the bottom of the box body is used as a breathing hole, and the water leakage hole has the functions of water leakage and air circulation. In the third mode, the side wall of the box body or the operation door is provided with the breathing grating, and the brim shielding part is arranged above the breathing grating, so that the ventilation purpose can be realized, and the dustproof and waterproof effects can be realized. In addition, the breathing grilles can be arranged on the side walls of the box body on two opposite sides, so that convection can be formed. Furthermore, the breathing grids on one side can be arranged above one side wall, and the breathing grids on the other side are arranged below the other side wall, so that the convection range is improved. It should be noted that the above implementation manners are only limited examples, and similar modifications and extensions can be made without limiting the protection scope of the present invention.

On the other hand, the outdoor display screen can be subjected to sand and dust due to the characteristic of outdoor use, so that a dustproof net can be arranged at the position of a breathing hole or a breathing grating, the outdoor display screen specifically comprises an adjustable and foldable spiral-structure net rack and a filter screen, the spiral-structure net rack comprises a plurality of spiral blades, one ends of the spiral blades are connected through a lock catch, and the rotation of the lock catch drives the spiral blades to rotate, so that the spiral blades are in an opening and closing state. The start of the helical blades can be controlled by means of wind speed control, manual control or intelligent setting. Therefore, sand and dust can be effectively isolated in the outdoor display screen box body, and the safety and the reliability of outdoor use are improved.

The invention also provides an outdoor display screen which comprises any one of the outdoor display screen protection structures, wherein the outdoor display screen electrical equipment is arranged in the box body and can protect a plurality of modules of circuits in the display screen.
