[0027] See also Figure 1-5 , the utility model provides a technical solution:

[0028] An advertising backboard that is easy to maintain, comprising:

[0029] The two ends of the housing 100 are rotatably connected with connecting columns 121, and the side wall of the connecting column 121 is rotatably connected with the middle piece 120. The middle piece 120 is in an H-shaped structure. The two sides of the middle piece 120 are matched with fixing parts 110. The fixing part 110 is fixed to the wall. The fixing part 110 is provided with a rotating column 112 matched with the middle piece 120 inside. The top of the rotating column 112 is rotatably connected with a sliding column 113. The side wall of the fixing part 110 is provided with a sliding groove 111 matched with the sliding column 113. The side wall of the fixing part 110 is provided with a locking part 114. The locking part 114 is fixed to the wall with bolts. The locking part 114 is provided with a sliding block 115 matched with the sliding groove 111.

[0030] The rear cover 200 is snap-fitted to the rear side of the housing 100. A lamp board 102 is provided inside the housing 100 to fit the side wall of the rear cover 200. A plurality of common LED lamp beads are provided on the side wall of the lamp board 102. A common battery for powering the LED lamp beads is provided on the rear side of the lamp board 102. A hydrophobic film 201 is provided on the rear side of the rear cover 200.

[0031] In some embodiments, the hydrophobic film 201 is a common plastic film on the market, and the side of the plastic film close to the wall is coated with hydrophobic oil. The main feature of the hydrophobic oil is that it can repel water, so that water droplets are formed on its surface instead of being wetted by water. This feature makes the hydrophobic oil play an important role in waterproofing and protecting equipment, machinery and surfaces from water erosion.

[0032] The side wall of the hydrophobic film 201 is provided with multiple partitions 210, and the top of the outer shell 100 is fixed with a top component 220 by bolts. The top component 220 is made of hard plastic commonly available on the market. A water-absorbing cotton strip 221 is embedded in the top of the top component 220. The top of the top component 220 is fixed with a water collecting trough 230 by bolts, and the top of the water collecting trough 230 is fixed with a wall-sticking piece 232. The wall-sticking piece 232 is a common plastic film commonly available on the market, and its rear side is adhered to the wall with glue. Both ends of the water collecting trough 230 are fixed with drainage grooves 231 by bolts.

[0033] Specifically, an inclined plate is disposed on the front side of the top component 220 , and a plurality of guide grooves 222 are formed on the outer wall of the inclined plate, so as to reduce rainwater from rushing toward the front side wall of the housing 100 .

[0034] Furthermore, a plurality of transparent plates 101 are embedded in the front side wall of the housing 100 . The transparent plates 101 are common acrylic plates on the market. Advertisement papers and other materials to be displayed can be placed on the front side of the transparent plates. The transparent plates 101 are matched with the side walls of the light panels 102 .

[0035] It is worth noting that a plurality of partition columns 211 are disposed inside the partition member 210 , and moisture absorbing strips 212 are disposed on the side walls of the partition columns 211 .

[0036] It is worth noting that a knob is provided on the side wall of the locking member 114, and a limit bar is provided on the side wall of the slider 115 to cooperate with the locking member 114. The limit bar cooperates with the slider 115 to slide inside the locking member 114 to prevent the slider 115 from detaching from the locking member 114 when sliding.

[0037] Working principle: when the shell 100 needs to be flipped open, first loosen the knob of the locking piece 114 and pull the slider 115 outward so that the slider 115 moves out of the inside of the slide groove 111, and then pull the shell 100 forward so that the rotating column 112 rotates in cooperation with the middle piece 120 while the sliding column 113 slides toward the middle inside the slide groove 111, then flip the shell 100 so that the shell 100 rotates in cooperation with the connecting column 121, and then slide the back cover 200 to open the shell 100, so that the advertising backboard can be quickly detached from the wall and flipped open, so that the advertising backboard can be easily maintained, which is convenient. When rainwater flows downward along the wall, the wall-sticking piece 232 will guide the rainwater on the wall into the water collection trough 230, and then the rainwater will be discharged from the drainage trough 231. At the same time, the absorbent cotton strip 221 is close to the wall and will absorb the moisture that penetrates downward from the wall. The partition 210 will separate the back cover 200 of the outer shell 100 from the wall, so that there is a gap between the back cover 200 and the wall. At the same time, the moisture-absorbing strip 212 of the partition 210 can also absorb the moisture between the hydrophobic film 201 of the back cover 200 and the wall, so that the rainwater flowing downward along the wall can be separated from the advertising backboard, preventing the rainwater from penetrating into the inside of the advertising backboard along the wall, and having a waterproof protection effect on the components inside the advertising backboard.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
