DETAILED DESCRIPTION

[0024] Example

[0025] See also Figure 1-5 , the utility model provides a technical solution:

[0026] An intelligent rainproof and easily disassembled advertising sign, wherein the upper surface of the mounting frame 1 is fixedly connected with a shell 2, and a mounting back plate 3 is installed inside the shell 2. The mounting back plate 3 is used to install and fix electronic components. By installing a skilled device composed of different numbers of light-emitting diodes, controllers, converters, sensors and other components on the mounting back plate 3, the playing of advertising images is further realized. A playing window 4 is provided on the surface of the shell 2, and the playing window 4 is located in front of the mounting back plate 3. Further, the user can watch the advertising content played by the electronic components on the mounting back plate 3 through the playing window 4 to realize advertising display. Two groups of fixing rods 5 are fixedly connected to the inner wall of the shell 2, and the two groups of fixing rods 5 are distributed in parallel, and the mounting back plate 3 is located between the two groups of fixing rods 5. The surfaces of the two groups of fixing rods 5 are sleeved with a mounting frame 6, and the surface of the mounting frame 6 is fixedly connected with a glass 7. The installation frame 6 is installed inside the shell 2 and is located outside the playback window 4. The area of ​​the glass 7 is larger than the area of ​​the playback window 4. The installation frame 6 and the glass 7 can further seal the playback window 4, so that the glass 7 does not affect the viewing of the display advertisements on the surface of the installation back panel 3, and can prevent rain and dust from entering the interior of the shell 2 and causing damage to the electrical components.

[0027] Two sets of slide rail frames 9 are fixedly connected to the inner wall of the upper end of the shell 2, and the two sets of slide rail frames 9 are distributed on both sides of the interior of the shell 2. A slide groove 10 is provided inside the slide rail frame 9, and a cross bar 11 is inserted into the slide groove 10 to further realize the sliding installation of the cross bar 11 between the two sets of slide rail frames 9. The installation back plate 3 is installed on the lower end surface of the cross bar 11, so that the installation back plate 3 can be adjusted in height with the vertical sliding of the cross bar 11. The lower end surface of the shell 2 is provided with an opening and a sealing cover is installed on the opening. The installation back plate 3 is slid out through the lower end opening of the shell 2, which is convenient for the installation back plate 3 to be pulled out from the shell 2 and the electronic components to be installed on the surface, while preventing the entry of rainwater. Two sets of limiting mechanisms are arranged on the inner wall of the slide rail frame 9, located at the upper and lower ends of the slide groove 10. The limiting mechanisms include two sets of mounting grooves 13 arranged on the surface of the slide rail frame 9. Both sets of mounting grooves 13 face one side of the slide groove 10 and are provided with openings. A clamping bead 14 is inserted inside the mounting groove 13. The clamping bead 14 is inserted inside the mounting groove 13 and fixedly connected to a spring B15 on one end surface thereof. The other end of the spring B15 is connected to the inner wall of the mounting groove 13. At the same time, two sets of spherical limiting grooves 12 are arranged on one end surface of the cross bar 11 inserted into the inner wall of the slide groove 10. The clamping bead 14 and the spherical limiting groove 12 are adapted. When the cross bar 11 slides inside the slide groove 10 and adjusts the height of the mounting back plate 3, when the cross bar 11 slides to the top of the slide groove 10, the clamping bead 14 is inserted into the spherical limiting groove 12 under the elastic force of the spring B15, further limiting the height of the cross bar 11, and realizing the installation and fixation of the mounting back plate 3 to the electronic components. Furthermore, the electronic components installed on the surface of the mounting back plate 3 are relatively light in weight and will not pull the mounting back plate 3 to overcome the elastic force of the spring B15. A handle 16 is fixedly connected to the lower end surface of the mounting back plate 3. When the electronic components on the surface of the mounting back plate 3 need to be disassembled and replaced, the mounting back plate 3 is pulled downward by the handle 16, and the card bead 14 is further pushed by the cross bar 11 to squeeze the spring B15 and insert into the mounting groove 13, so that the cross bar 11 is driven to slide inside the slide groove 10, and the cross bar 11 is further driven to slide to the lowest end inside the slide groove 10. At this time, the mounting back plate 3 is extended from the inside of the housing 2, so that the electronic components on the mounting back plate 3 can be easily maintained and repaired.

[0028] A sealing gasket 20 is fixedly connected to the outer surface of the installation frame 6. The sealing gasket 20 is located at the periphery of the playback window 4. The cross section of the sealing gasket 20 is set to be "L"-shaped. A spring A8 is sleeved on the surface of the fixing rod 5. One end of the spring A8 is connected to the inner wall of the shell 2, and the other end of the shell 2 is connected to the surface of the installation frame 6. Further, after the installation frame 6 is installed inside the shell 2, the sealing gasket 20 is located between the installation frame 6 and the shell 2. Under the elastic force of the spring A8, the installation frame 6 always slides toward the side of the sealing gasket 20, further abuts against the surface of the sealing gasket 20 and is pressed. The gap between the installation frame 6 and the playback window 4 is sealed by the sealing gasket 20, further improving the sealing performance inside the installation frame 1, and preventing rainwater from penetrating through the gap between the installation frame 6 and the playback window 4.

[0029] Two sets of fixed shafts 17 are inserted on both sides of the upper end surface of the mounting back plate 3, and rollers 18 are fixedly connected to the surfaces of the two sets of fixed shafts 17. Two sets of push blocks 19 are fixedly connected to the inner surface of the mounting frame 6, and the two sets of push blocks 19 are respectively located on one side of the two sets of rollers 18, and the push blocks 19 are set in a trapezoidal shape. When the mounting back plate 3 slides out from the inside of the housing 2 and the electronic components are installed, when the mounting back plate 3 is pushed into the inside of the housing 2 for installation, the rollers 18 will be pushed to slide linearly along the surface of the push blocks 19, and the push blocks 19 will be pushed to slide toward the side of the sealing gasket 20, so that after the mounting back plate 3 is installed, the push blocks 19 can be tightly against the surface of the sealing gasket 20, thereby improving the sealing effect. In addition, the mounting port of the mounting back plate 3 is located below the housing 2, so that there is no opening gap above the housing 2, rainwater leakage is avoided, and the sealing inside the housing 2 is further improved. And when the mounting back plate 3 slides out from the inside of the shell 2, the roller 18 cannot engage the push block 19, further loosening the top of the mounting frame 6. At this time, the mounting frame 6 can be pushed to slide on the surface of the fixing rod 5 and squeeze the spring A8, so as to facilitate the replacement of the sealing gasket 20 on the surface of the mounting frame 6. After the replacement is completed, with the installation of the mounting back plate 3, the sealing gasket 20 can be automatically tightened, thereby improving the convenience of replacing the sealing gasket 20.

[0030] The lower end surface of the playback window 4 and the lower end surface of the sealing gasket 20 are both arranged from inside to outside and from high to low, so that after rainwater falls on the surface of the glass 7, it can be quickly diverted out through the sealing gasket 20 to avoid rainwater gathering at the playback window 4 and causing infiltration.
