Description

Technical Field

[0001] This utility model relates to the field of advertising sign technology, specifically to an advertising sign that is easy to maintain. Background Technology

[0002] In current commercial activities, businesses often use advertising signs to attract customers for advertising purposes. Advertising signs are a type of advertising board that uses projected lighting for marketing, achieving good publicity and eye-catching effects. Currently used advertising signs are mostly installed using bolts on the back cover. During maintenance, these bolts need to be disassembled one by one, which is inconvenient for timely repairs. Therefore, designing an advertising sign that is easy to maintain is very important. For example:

[0003] An advertising sign with authorization announcement number CN205621386U includes: a lightbox body forming the outer frame of the advertising sign; a sensing device located inside the lightbox body for detecting the temperature of the lightbox body and sending temperature information outward; a control device connected to the sensing device for receiving the temperature information and sending a control signal and an alarm signal outward; a power supply device connected to the control device for turning on or off according to the control signal; and a warning device connected to the control device for sending an alarm command according to the alarm signal. By adopting the above technical solution, the power supply can be automatically cut off according to the temperature to prevent the advertising sign from catching fire. The beneficial effects of this advertising sign are: the advertising sign will automatically detect the internal temperature and cut off the power supply according to the temperature, while users can be informed of the advertising sign's malfunction immediately.

[0004] Based on existing solutions and actual production and processing, existing advertising signs have the following shortcomings, such as:

[0005] 1. Although existing advertising signs automatically detect internal temperature, it is difficult to prevent the outer wall of the advertising sign from remaining intact after external impact. Adding a protective plate can effectively prevent damage to the edges of the advertising sign caused by bumps.

[0006] 2. Although existing advertising signs can cut off the power supply based on temperature, it is difficult to quickly repair damaged internal parts after they are installed on the wall. Designing the advertising sign as a front-opening door can solve the problem of inconvenient maintenance. Therefore, this utility model provides an advertising sign that is easy to maintain in order to solve the above-mentioned problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5 This utility model provides a technical solution: an advertising sign that is easy to maintain, including a protective plate body 1, a limiting groove 2, an advertising sign body 3, a protective door 4, a limiting frame 5, an acrylic plate 6, a positioning groove 7, a support foot 8, a solar panel 9, a photovoltaic cell 10, a lamp tube body 11, a limiting plate 12, a handle 13, a heat dissipation vent 14, an exhaust fan 15, a connecting assembly 16, a connecting plate 1601, a connecting plate 1602, a connecting bolt 1603, a fixing block 17, and a fixing bolt 18.

[0030] Specific examples Figure 1 , Figure 4 and Figure 5 As shown, first, hold the handle 13 on the outside of the protective plate body 1, and align the symmetrical limiting plates 12 on the outside of the advertising sign body 3 with the limiting grooves 2 opened inside the protective plate body 1. The limiting plates 12 engage in the limiting grooves 2 and connect with the protective plate body 1. The connecting plates 1601 set at the inner end of the protective plate body 1 contact the upper and lower sides of the advertising sign body 3. On the outside of the two adjacent sets of connecting plates 1601, the connecting plates 1602 in the shape of a "U" are fitted. The connecting plates 1601 are symmetrical about the center line of the connecting plates 1602. A portion of the connecting plate 1601 extends into the interior of the connecting plate 1602. Then, the connecting bolt 1603 is tightened at the connection between the connecting plate 1601 and the connecting plate 1602. The connecting bolt 1603 included in the connecting assembly 16 passes through the interior of the connecting plate 1602, tightly connecting the connecting plate 1601 and the connecting plate 1602. At this time, the left and right sides of the advertising sign body 3 are protected by the protective plate body 1, which facilitates the protection function of the advertising sign. The addition of the protective plate can effectively prevent the edges of the advertising sign from being damaged by bumps.

[0031] Specific examples Figure 1 , Figure 3 and Figure 5As shown, firstly, an "L"-shaped fixing block 17 is welded to the outside of the protective plate body 1. The fixing blocks 17 are symmetrically distributed at the top and bottom of the outer end of the protective plate body 1. Holding the handle 13 on the outside of the protective plate body 1, the entire advertising sign is lifted. After the back of the protective plate body 1 contacts the open wall, the fixing bolt 18 is screwed into the inside of the fixing block 17. The fixing bolt 18 fixes the fixing block 17 and its entirety to the wall surface by means of the external thread structure. The fixing block 17 and the wall surface are reinforced by the fixing bolt 18, which facilitates the quick installation of the advertising sign.

[0032] Specific examples Figure 1 , Figure 2 and Figure 5 As shown, firstly, the support foot 8 connected to the lower side of the solar panel 9 is placed on the upper side of the advertising sign body 3. The photovoltaic cell 10 on the lower side of the solar panel 9 can convert the sunlight absorbed by the solar panel 9 into electrical energy. The photovoltaic cell 10 is engaged with the upper side of the advertising sign body 3. The lower side of the photovoltaic cell 10 is provided with symmetrical lamp tube bodies 11. The longitudinal section of a single lamp tube body 11 is U-shaped. Then, the acrylic plate 6 is aligned with the positioning groove 7 opened on the right side of the limiting frame 5, and the acrylic plate 6 is pushed so that the acrylic plate 6 enters the interior of the positioning groove 7. The acrylic plate 6 is engaged with the limiting frame 5 through the positioning groove 7. After the lamp tube body 11 lights up, the internal light illuminates the printing on the acrylic plate 6. The sign displays the characters and patterns. However, when the sign needs maintenance, simply open the protective door 4 on the front of the sign body 3 to inspect or replace the light tube body 11 connected to the photovoltaic cell 10. This facilitates quick maintenance of the sign. At the same time, an exhaust fan 15 is installed at the bottom of the sign body 3, and the interior of the sign body 3 has heat dissipation vents 14 that correspond to the exhaust fan 15. When the light tube body 11 is lit, the exhaust fan 15 is turned on, and the heat dissipation vents 14 dissipate the heat generated by the light tube body 11 through the exhaust fan 15, thus completing the heat dissipation function of the sign. This is how to use this convenient sign.
