Technical Field

[0001] The utility model relates to the technical field of advertising light boxes, in particular to an advertising light box with an automatic door opening device. Background Art

[0002] An advertising light box is a box made using light as a light source and configured with text or patterns. With the continuous development of the social economy, its application scope is also continuously expanding. It can be seen in places such as the waiting halls of railway stations, bus stop signs, shopping malls, subway stations, airports, high-speed railway stations, business districts, and bus shelters.

[0003] Nowadays, advertising light boxes can be seen everywhere. Advertising light boxes are used to display the images of businesses and enterprise products, enabling people to better understand these products. Traditional advertising light boxes usually use nuts and screws to fix the advertising light box to the wall. When product information needs to be updated or the advertising light box needs to be cleaned and scrubbed, the traditional installation method requires tools such as wrenches to remove the nuts, and its operation steps are cumbersome, making it inconvenient to disassemble the advertising light box. At the same time, when the advertising light box needs to be installed, the installation is also inconvenient.

[0004] In addition, as disclosed in the Chinese patent document with the publication number CN205177354U, an upper-hinged hinged wall-mounted advertising light box is disclosed, which includes a light box body. A wall-connecting component is provided on the back of the light box body, and the light box body is fixed to the wall through the wall-connecting component. A light-emitting element is provided inside the light box body, and an advertising light-transmitting surface is provided on the front of the light box body. The wall-connecting component includes a hinged component and a receiving component. The hinged component is provided above the receiving component, and the hinged component hinges the back of the light box body to the wall. The receiving component includes a first cushion block and a second cushion block. The first cushion block is fixed to the wall, and the second cushion block is fixed to the back of the light box.

[0005] Although it solves to a certain extent the problem that traditional wall-mounted advertising light boxes require loosening a lot of screws every time they are replaced and removed, and thus it takes a lot of time to complete the replacement operation, and the operation is very cumbersome. However, when the size of the light box is increased, its hinged design also brings new problems. After the light box is enlarged, its panel is relatively heavy, and it is very strenuous to lift it, increasing the labor intensity of workers and being unsafe.

[0006] The existing light box billboards include a billboard body and a frame. The billboard body is clamped inside the frame to form a fixed whole, and its frame is usually fixed and connected by screws. When the advertising content in the billboard needs to be replaced, it needs to be disassembled and replaced with the help of special tools, and the operation is relatively troublesome.

Detailed implementation manners

[0037] The technical solutions in the embodiments of the present utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0038] Please refer to Figures 1 to 9 In the embodiments of the present utility model, an advertising light box with an automatic door opening device includes a light box body 10. The body is provided with a back plate 13, a frame 20 and a face cover 30. The back plate 13 and the face cover 30 are respectively installed on both sides of the frame 20, so as to form a box space inside the body. A light bar 11 and a picture frame 12 are arranged in the box space. The picture frame 12 is used to install an advertising picture, and the light bar 11 is used to illuminate the advertising picture. The back plate 13 is fixedly connected to one side of the frame 20, and the face cover 30 is movably connected to the other side of the frame 20 in an openable manner. After the face cover 30 is opened, the advertising picture or the light bar 11 can be replaced. An opening device 40 is arranged between the face cover 30 and the frame 20. One end of the opening device 40 is connected to the frame 20, and the other end is connected to the face cover 30, and is used to perform an opening operation on the face cover 30.

[0039] Specifically, after the advertising light box is installed, it is also necessary to replace the advertising picture installed inside it after the advertising display time expires. Therefore, it is necessary to frequently open the face cover 30 of the light box body 10 to replace the advertising picture. The traditional light box face cover 30 is not convenient to open. Especially when the light-transmitting plate 34 uses tempered glass, the weight of the face cover 30 itself is relatively heavy, and it is difficult for workers to open it manually. Moreover, when replacing the advertising picture, it is also necessary to keep the face cover 30 at a certain opening angle. If manually supported by workers, it is easy to cause fatigue and the support is not in place, which may lead to the risk of safety accidents.

[0040] Secondly, by arranging an automatic opening device 40 between the frame 20 and the face cover 30, the automatic opening operation of the face cover 30 can be realized, thus liberating the hands of workers, reducing the labor intensity of workers, and enhancing the operation safety. The remote control device and control chip in the existing products can also be used to perform intelligent control on the opening device 40, so that workers only need to use the remote control to remotely control the opening device 40 to start the opening device 40, so as to push the face cover 30 from the closed state, open it at a certain angle, which is convenient for replacing the advertising picture inside the light box or replacing components such as the light bar 11 inside the light box.

[0041] In addition, a light diffusing cloth (not shown in the figure) may be provided between the light bar 11 and the advertising picture, or between the advertising picture and the light-transmitting plate 34, so that the light emitted by the light bar 11 can be evenly irradiated on the advertising picture, or evenly irradiated out of the light-transmitting plate 34, thereby making the display effect of the light box more uniform.

[0042] As Figure 2 , Figure 4 and Figure 9 shown, preferably, a door hinge 24 is provided on one side of the top of the frame 20 facing the face cover 30. One end of the door hinge 24 is fixedly connected to the frame 20, and a strip-shaped round shaft 25 is formed at the other end thereof. A U-shaped groove 32 is provided on the face cover 30 corresponding to the strip-shaped round shaft 25, and the U-shaped groove 32 is sleeved on the strip-shaped round shaft 25, so as to form a rotational connection between the face cover 30 and the frame 20.

[0043] Specifically, in order to enable the face cover 30 to rotate relative to the frame 20, a corresponding rotational mechanism needs to be provided at the connection part between the side strip 31 and the frame 21. For example, the side strip 31 can be rotationally connected by using the door hinge 24 fixed on the frame 21. By using the rotational cooperation between the U-shaped groove 32 and the strip-shaped round shaft 25, the face cover 30 is rotationally connected to the frame 20.

[0044] As Figure 3 , Figure 6 and Figure 7 shown, preferably, the opening device 40 is provided with an electric push rod 41, the frame 20 is provided with a first rotating shaft 26, and the base end of the electric push rod 41 is rotationally connected to the first rotating shaft 26; the face cover 30 is provided with a second rotating shaft 35, and the connecting head of the push-out shaft of the electric push rod 41 is rotationally connected to the second rotating shaft 35.

[0045] Specifically, the electric push rod 41 can be set as the opening device 40, so that it can use the motor rotation to open the face cover 30. For example, the electric push rod 41 can adopt an electric screw rod in existing products, and use the motor rotation to drive the screw rod to rotate, thereby driving the corresponding output shaft to extend or retract, so as to realize the automatic opening or automatic closing of the face cover 30.

[0046] As Figure 6 and Figure 7 shown, preferably, the first rotating shaft 26 is provided with a first fixing block 27, and the first fixing block 27 is fixedly connected to the inner side wall of the frame 20 by bolt connection, and the first rotating shaft 26 is fixedly connected to the first fixing block 27. The second rotating shaft 35 is provided with a second fixing block 36, and the second fixing block 36 is fixedly connected to the inner side wall of the face cover 30 by bolt connection, and the second rotating shaft 35 is fixedly connected to the second fixing block 36

[0047] Specifically, in order to fix the opening device 40, corresponding first fixing blocks 27 can be provided on the frame 21, and a first rotating shaft 26 can be provided on the first fixing blocks 27. Thus, the base mounting end of the opening device 40 is mounted on the first rotating shaft 26 to form a rotational connection, so that during the opening process of the face cover 30, the opening device 40 can rotate around the first rotating shaft 26, thereby normally opening the face cover 30. Similarly, corresponding second fixing blocks 36 can be provided on the side strip 31, and a second rotating shaft 35 can be provided on the second fixing blocks 36. Thus, the pushing shaft of the opening device 40 is mounted on the second rotating shaft 35 to form a rotational connection, so that during the process of the opening device 40 pushing the face cover 30 to open, the face cover 30 can rotate around the second rotating shaft 35.

[0048] As Figures 5 to 7 shown, preferably, a latch device 50 is further provided between the frame 20 and the face cover 30. The latch device 50 is provided with a lock catch 51, a lock tongue 52, a torsion spring, a lock core 53 and a door lock pressing plate 54. The lock catch 51 is fixedly connected to the face cover 30. The door lock pressing plate 54 is fixedly connected to the inner side wall of the frame 20 at a position corresponding to the lock catch 51. One end of the lock core 53 extends out of the outer side of the frame 20, and the other end extends into the door lock pressing plate 54 and is rotationally connected to the door lock pressing plate 54. The lock tongue 52 is fixedly connected to the lock core 53. The torsion spring is sleeved on the lock core 53, one end of which abuts against the door lock pressing plate 54, and the other end abuts against the lock tongue 52, so that the lock tongue 52 maintains a locked state with respect to the lock catch 51.

[0049] Specifically, when closing the face cover 30, the lock catch 51 can just touch the bevel edge of the lock tongue 52, so that the lock tongue 52 rotates upward by a certain angle, thereby enabling the lock catch 51 to move a certain distance towards the door lock pressing plate 54. Subsequently, under the elastic drive of the torsion spring, the lock tongue 52 rotates downward by a certain angle, so that the lock tongue 52 hooks the lock catch 51 to form a locked state. Before the face cover 30 needs to be opened, the lock core 53 can be rotated on the outer side of the frame 20, so that the lock core 53 rotates by a certain angle, thereby driving the lock tongue 52 to rotate upward by a certain angle, and further releasing the lock catch 51, so that the face cover 30 can be normally opened.

[0050] As Figure 2 and Figure 3 shown, preferably, the frame 20 is formed by fixedly connecting a plurality of frames 21 end to end, and the plurality of frames 21 all have the same cross-sectional shape. A U-shaped groove 22 is provided on the side of the frame 21 close to the face cover 30, and the two side walls of the U-shaped groove 22 are folded inward by a certain length to form limiting edges 23.

[0051] Specifically, the U-shaped groove 22 is used to install the door hinge 24, so that the door hinge 24 can be fixed within the U-shaped groove 22. Preferably, the door hinge 24 moves into the groove from both sides of the U-shaped groove 22, and the edge of the fixed end of the door hinge 24 abuts against the limiting edge 23, thereby forming a fixed connection, enabling the face cover 30 to be stably rotatably connected to the door hinge 24. To simplify the production of the light box and reduce its production cost, all the frames 21 of the light box can be set as profiles with the same cross-sectional shape, thereby simplifying its assembly process and reducing the cost of its raw materials. Profiles with the same cross-sectional shape, such as aluminum alloy profiles, only require one set of molds during production. Corresponding functional parts can be provided on the profiles so that when they are installed as horizontal frames 21 or vertical frames 21, they can have different functions. It can be understood that at the connection of all the frames 21 of the frame 20, reinforcing angle irons or angle aluminum can also be provided to make the connection of the frames 21 more stable.

[0052] As Figure 2 and Figure 5 shown, preferably, the face cover 30 is formed by fixedly combining a plurality of side strips 31 connected end to end with each other, and all the side strips 31 have the same cross-sectional shape. A U-shaped groove 32 is provided on one side of the side strip 31 close to the frame 20, and a C-shaped groove 33 is provided on the other side thereof. The C-shaped groove 33 is used to install the light-transmitting plate 34 of the face cover 30.

[0053] Specifically, all the side strips 31 of the face cover 30 can also be set as profiles with the same cross-sectional shape, thereby achieving corresponding assembly simplification and cost reduction. At the connection of the side strips 31, reinforcing angle irons or angle aluminum can also be provided to make the connection of the side strips 31 more stable.

[0054] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed within the present utility model.
