Description

Technical Field

[0001] The present application relates to the field of advertising light boxes, and in particular to an outdoor advertising light box. Background Art

[0002] Advertising light boxes are a common promotional medium, widely used in various places such as supermarkets and shops. During manufacturing, related technologies require that a hole be opened in the box body for threading the power cord of the LED light panel. After the LED light panel is installed in the box body, the power cord is passed through the hole and out of the box body, allowing the power cord to be connected to the power supply line to power the LED light panel.

[0003] Regarding the above-mentioned related technologies, when the advertising light box is used outdoors, the power cord exposed on the outside of the box is exposed to wind and sun for a long time, which can easily lead to premature aging, resulting in cracks on the surface of the power cord and even leakage. On the other hand, the exposed wires can easily affect the overall appearance of the advertising light box; therefore, there is room for improvement. Utility Model Content

[0004] In order to better store the power cord of the advertising light box and reduce the aging and damage of the power cord due to exposure to the outdoors, the present application provides an outdoor advertising light box.

[0005] This application provides an outdoor advertising light box, which adopts the following technical solutions:

[0006] An outdoor advertising light box includes a box body, an LED light board and a panel. The box body is opened on one side, the LED light board is installed in the inner cavity of the box body, and the LED light board is connected to a power cord; the panel is installed at the opening of the box body; a suspension rod is connected to the outside of the box body, and a connecting piece is provided at the top of the suspension rod; the interior of the suspension rod is hollow and open at both ends, and the inner cavity of the suspension rod is connected to the inner cavity of the box body; the power cord is passed through the inner cavity of the suspension rod.

[0007] By adopting the above technical solution, when installing an outdoor advertising light box, the hanging rod on the box body is connected to the outdoor wall or ceiling of the building through a connector to complete the installation and fixation of the advertising light box; by passing the power cord of the LED light panel through the hanging rod, the power cord can be stored and organized inside the hanging rod, making it less likely for the power cord to be exposed to the outdoor environment for a long time, which may lead to aging and damage.

[0008] Preferably, the connecting member includes a connecting seat connected to the top end of the suspension rod, and a plurality of through holes are evenly opened on the connecting seat.

[0009] By adopting the above technical solution, after the top of the connecting seat is abutted against the wall or ceiling, the expansion screws are driven into the wall or ceiling through the several through holes on the connecting seat, thereby achieving a stable connection between the hanger and the wall or ceiling.

[0010] Preferably, a receiving groove is formed in a recessed manner on the top of the connecting seat, and the receiving groove is connected to the inner cavity of the suspension rod.

[0011] By adopting the above technical solution, after the power cord of the LED light panel is subsequently connected to the power supply wire pre-buried in the wall or ceiling, the excess part of the power cord extending outside the suspension rod can be stored in the storage groove. On the one hand, the power cord does not need to be exposed to the outside world, and on the other hand, the situation in which the excess part of the power cord extending outside the suspension rod interferes with the normal installation of the connecting socket is reduced.

[0012] Preferably, the outer periphery of the power cord is provided with a flexible protective sheath.

[0013] By adopting the above technical solution, the power cord is wrapped and protected with a flexible protective cover, which helps to reduce the wear of the outer layer of the power cord caused by friction between the power cord and the inner wall or end edge of the boom when the power cord is subsequently inserted into the boom or dragged when the power cord is subsequently connected.

[0014] Preferably, a flexible rubber layer is laid on the top of the connecting seat.

[0015] By adopting the above technical solution, through the provision of a flexible rubber layer, on the one hand, flexible contact between the connecting seat and the outdoor wall or ceiling is achieved, thereby reducing the possibility of the connecting seat causing extrusion damage to the wall or ceiling during the subsequent installation and fixing of the connecting seat; on the other hand, the flexible rubber layer can better seal the gap between the connecting seat and the wall or ceiling, thereby reducing the possibility of external moisture or dust entering the connecting groove of the connecting seat and corroding the power cord.

[0016] Preferably, a connecting ring is connected around the outer periphery of the panel, the connecting ring is sleeved on the outer periphery of the box, and the connecting ring is connected to the box body through a plurality of connecting bolts.

[0017] By adopting the above technical solution, the panel can be detachably installed at the opening of the box, which facilitates the installation and replacement of the LED light board inside the box.

[0018] Preferably, a rubber ring is sleeved on the outer periphery of the box, and the rubber ring is arranged to abut against the inner periphery of the connecting ring.

[0019] By adopting the above technical solution, the gap between the box body and the connecting ring is sealed with a rubber ring, which is conducive to limiting external water vapor from entering the box body through the gap between the box body and the connecting ring and causing corrosion to the LED light board and power cord inside the box body.

[0020] Preferably, an annular limiting groove is provided on the outer periphery of the box body corresponding to the rubber ring, and the inner periphery of the rubber ring is embedded in the annular limiting groove.

[0021] By adopting the above technical solution, the annular limiting groove is used to limit the rubber ring, which is conducive to reducing the situation where the rubber ring is dragged by the connecting ring and displaced during the subsequent disassembly and assembly of the panel.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By setting up a hollow hanging rod and connecting the inner cavity of the hanging rod with the inner cavity of the box, after the LED light panel is installed in the box, the power cord of the LED light panel can be passed through the hanging rod to store the power cord inside the hanging rod, reducing the power cord from being exposed to the outside of the advertising light box for a long time, which makes the power cord easy to age and be damaged.

[0024] 2. By setting the storage groove on the top of the connecting base, the excess part of the power cord extending outside the boom can be stored in the storage groove, which limits the exposure of the power cord to the outside world and helps to reduce the interference of the excess part of the power cord extending outside the boom with the normal installation and fixation of the connecting base.

[0025] 3. By providing a flexible rubber layer on the top of the connector, after the connector is fixed to the wall or ceiling with expansion screws, the flexible rubber layer can be used to achieve a flexible connection between the connector and the wall or ceiling, dispersing the load acting on the wall or ceiling. At the same time, the flexible rubber layer can better seal the gap between the connector and the wall or ceiling, limiting external moisture from entering the connector and corroding the power cord.

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The present application discloses an outdoor advertising light box. Figure 1 and Figure 2 , including a box body 1, an LED light board 2 and a panel 3; an opening is set on one side of the box body 1, the panel 3 is installed at the opening of the box body 1 and the panel 3 covers the opening of the box body 1, the LED light board 2 is installed in the inner cavity of the box body 1, and the LED light board 2 is connected to the power cord 21; two suspension rods 11 are welded and fixed on the outer periphery of the box body 1, the two suspension rods 11 are set in parallel, the interior of the suspension rods 11 is hollow and both ends of the suspension rods 11 are open; the inner cavities of the suspension rods 11 are connected to the inner cavity of the box body 1; the end of the power cord 21 away from the LED light board 2 is passed through a suspension rod 11 and extends out of the top of the suspension rod 11.

[0034] Reference Figure 1 and Figure 3 The connector includes a connector base 12, the bottom of which is welded to the top end of the suspension rod 11. Connecting base 12 is provided with a plurality of through-holes 120 for inserting expansion screws. When subsequently securing the suspension rod 11 to a wall or ceiling outside a building, after placing the connector base 12 against the wall or ceiling, the expansion screws are inserted through the through-holes 120 and driven into the wall or ceiling, thereby securely mounting the suspension rod 11 to the wall or ceiling.

[0035] The top of the connecting seat 12 is also recessed to form a storage groove 121; the bottom of the storage groove 121 corresponds to the beginning of the hanger 11 with a connection port, which is connected to the opening at the top of the hanger 11, so that the storage groove 121 is connected to the inner cavity of the hanger 11, and the power cord 21 can subsequently enter the storage groove 121 through the connection port. Through the provision of the storage groove 121, after the power cord 21 extending from the top of the hanger 11 is connected to the power supply wire pre-buried in the wall or ceiling, the part of the power cord 21 extending from the top of the hanger 11 can be moved into the storage groove 121 to store the power cord 21, limiting the exposure of the power cord 21 to the outside world while reducing the interference of the part of the power cord 21 extending from the top of the hanger 11 on the normal installation of the connecting seat 12.

[0036] The top end surface of the connection base 12 is also fully covered with a flexible rubber layer 122; the bottom of the flexible rubber layer 122 is bonded to the connection base with glue. Through the provision of the flexible rubber layer 122, on the one hand, after the connection base 12 is subsequently fixed to the wall or ceiling with expansion screws, the flexible rubber layer 122 can be used to achieve flexible contact between the connection base 12 and the wall or ceiling, which is conducive to dispersing the load applied by the connection base 12 to the wall or ceiling and reducing the possibility of the connection base 12 causing extrusion damage to the wall or ceiling. On the other hand, the flexible rubber layer 122 can be used to block the gap between the top of the connection base 12 and the wall or ceiling to limit the subsequent entry of external water vapor into the connection groove, thereby reducing the possibility of water vapor corrosion and damage to the power cord 21 in the connection groove.

[0037] Reference Figure 1 and Figure 2 Two supporting columns are protruding from the inner wall of the box body 1; two fastening bolts are passed through the LED panel 3 corresponding to the two supporting columns, and the two fastening bolts are respectively threadedly connected to the two supporting columns, so that the LED panel 3 is firmly installed in the box body 1.

[0038] Reference Figure 1 and Figure 2 The outer periphery of the power cord 21 is provided with a flexible protective sleeve 22. In this embodiment, the flexible protective sleeve 22 is a PET woven mesh sleeve. In other embodiments, it can also be replaced by a rubber sleeve. One end of the flexible protective sleeve 22 extends to the connection between the power cord 21 and the LED light board 2, and the other end extends to the connection sleeve of the connection seat 12. Both ends of the flexible protective sleeve 22 are fixed to the power cord 21 by electrical tape. The flexible protective sleeve 22 is used to wrap and protect the power cord 21 of the LED light board 2, thereby reducing the friction between the power cord 21 and the inner cavity of the hanger 11 or the edge of the end of the hanger 11 when the power cord 21 is subsequently passed through the hanger 11 or when the power cord 21 is connected to the power supply wire and dragged, which may cause the surface of the power cord 21 to be easily damaged.

[0039] Reference Figure 1 and Figure 4 In this embodiment, panel 3 is a PVC color plate. In other embodiments, panel 3 can also be a colored glass color plate. A connecting ring 31 is coaxially connected to the outer periphery of panel 3; connecting ring 31 is sleeved on the outer periphery of housing 1. Several connecting bolts are threaded through the outer periphery of connecting ring 31 and are threaded into the outer side of housing 1 to secure connecting ring 31 to the outer side of housing 1. This arrangement allows panel 3 to be removably mounted on housing 1. When subsequently installing or replacing LED light board 2, panel 3 can be removed from housing 1, facilitating disassembly and replacement of LED light board 2.

[0040] A rubber ring 13 is also sleeved around the outer periphery of the housing 1, staggered relative to the connecting bolts. Rubber ring 13 is positioned near the opening of the housing 1, and its outer periphery abuts the inner periphery of the connecting ring 31. Using rubber ring 13 to block the gap between the outer periphery of the housing 1 and the inner periphery of the connecting sleeve helps prevent external moisture from entering the housing 1 through the gap between the housing 1 and the connecting sleeve and potentially corroding the LED light board 2 and power cord 21.

[0041] An annular limiting groove 10 is provided on the outer periphery of the box body 1 corresponding to the rubber ring 13; the inner periphery of the rubber ring 13 is embedded in the annular limiting groove 10, and the annular limiting groove 10 is used to limit the rubber ring 13 to prevent the rubber ring 13 from slipping due to force when the connecting ring 31 is subsequently disassembled and assembled, which is conducive to the rubber ring 13 being more firmly connected to the outer periphery of the box body 1.

[0042] The implementation principle of the embodiment of the present application is as follows: when manufacturing an advertising light board, the LED light panel 2 is fixed to the box body 1 by fastening bolts, and the power cord 21 of the LED light panel 2 is inserted into the suspension rod 11 and extended into the storage groove 121 of the connecting seat 12 at the top of the suspension rod 11. Then, the connecting ring 31 on the outer periphery of the panel 3 is inserted into the outer periphery of the box body 1 and fixed to the outside of the box body 1 by connecting bolts. By inserting the power cord 21 of the LED light panel 2 into the suspension rod 11, the suspension rod 11 is used to store the power cord 21, thereby reducing the power cord 21 from being directly exposed to the outside of the box body 1, which may cause aging and damage.

[0043] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
