Description

Technical Field

[0001] The invention relates to the technical field of advertising light boards, and in particular to a wind-resistant advertising light board. Background Art

[0002] Wind-resistant advertising light billboards are advertising display devices designed to resist the impact of strong winds. They are widely installed on outdoor high-height support structures. The design of wind-resistant advertising light billboards usually combines mechanical transmission and automatic adjustment mechanisms. For example, existing wind-resistant billboards, through special design and material selection, can withstand the impact of strong winds and ensure the continuous display of advertising content. At the same time, the use of a stable support structure and connection method reduces the risk of billboards falling off or being damaged in strong winds, ensuring the safety of pedestrians and vehicles.

[0003] At present, most billboards are installed at high altitudes by bolt assembly or frame welding. Once installed, the stable support requirements of the billboards can only be met by strengthening the supporting strength of the supporting structure. However, under extreme weather conditions such as typhoons and heavy rains, measures still need to be taken in advance to reinforce and protect the billboards. If the wind is strong and exceeds the strength limit of the supporting structure, the supporting structure will crack or directly break, causing safety accidents such as falling from a high altitude and injuring passers-by and vehicles, posing a safety risk.

When there is no wind, the light board is reset to form a ring-shaped structure display frame again, which is used for advertising display. The wind-receiving area of ​​the display board can be automatically adjusted according to the wind force, and there is no need to set the electric component adjustment operation, and the advertising board can be effectively protected from being damaged.

[0032] The following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Embodiment, this embodiment provides a wind-resistant advertising light board, such as Figure 1 , Figure 2 and Figure 3 As shown, the advertising installation includes a bottom plate 2, a top plate 21 and a plurality of light signs, wherein, Fig.10 As shown, the light board includes a lampshade 3 and a sealing plate 32 installed at the opening of the lampshade 3. The lampshade 3 has a mounting cavity built therein. The space in the mounting cavity is used to place the advertising content board. The lampshade 3 is made of transparent acrylic plastic, which can clearly display the advertising content board located in the mounting cavity. Fig.11 As shown, a lamp holder 31 is fixed in the middle of the outer wall of the sealing plate 32, an LED 33 is embedded in the lamp holder 31, and a light-transmitting opening is provided on the side wall of the lamp holder 31 facing the lampshade 3 and the side wall of the sealing plate 32. The LED 33 is placed into the lamp holder 31 through the light-transmitting opening and connected to the connector in the lamp holder 31 to ensure that the circuit of the LED 33 is connected. When the LED 33 lights up, the light is transmitted through the light-transmitting opening to illuminate the advertising content board in the lampshade 3, so that people can view the advertising content from a distance at night.

[0034] Mounting blocks are provided at the corners of the mounting cavity, and mounting holes are provided at the corners of the sealing plate 32. After the LED 33 and the advertising content board are installed, the mounting cavity of the lampshade 3 is arranged opposite to the sealing plate 32, and fastening bolts are installed between the mounting holes and the mounting blocks, thereby splicing the sealing plate 32 and the lampshade 3 together, which can prevent rainwater and dust from entering the lampshade 3 and preventing the LED 33 circuit from getting damp, and at the same time prevent excessive dust in the lampshade 3 from affecting the clear display of the advertising content.

[0035] like Figure 1 As shown, multiple light boards are arranged in a ring structure at the edge between the top plate 21 and the bottom plate 2 to form a ring structure display frame for advertising display. Here, the traditional integral structure of the light board is split into multiple individual units. In this way, on the first floor, as long as multiple light boards are spliced ​​together in a ring structure, the advertising content can be completely arranged on a ring structure display frame, and the advertising content can be displayed 360 degrees, which is particularly suitable for displaying promotional advertisements in downtown areas or scenic spots.

[0036] The present embodiment also discloses a supporting structure, which includes a longitudinal supporting column 11 for supporting the chassis 2, that is, for supporting an advertising display frame composed of a plurality of light signs. Figure 1 and Figure 2 As shown, there are multiple longitudinal support columns 11, and the multiple longitudinal support columns 11 are evenly spaced and arranged in a ring structure. An arc-shaped reinforcing rod is fixed between two adjacent longitudinal support columns 11. A base 1 is welded to the bottom end of the multiple longitudinal support columns 11. When installing the support structure, a foundation pit is dug in the pre-buried ground, the base 1 is placed in the foundation pit, and concrete is poured. Finally, the entire base 1 is poured below the ground surface, and above the ground surface are multiple longitudinal support columns 11. The special design here is that, first, the multiple longitudinal support columns 11 have sufficient fatigue resistance to support the chassis 2 and multiple light billboards to display advertisements at high altitudes. Secondly, the traditional method of using a single column structure as a support member is changed, and a gap is left between two adjacent longitudinal support columns 11. The purpose of these gaps is to exhaust air, minimize the windward surface of the longitudinal support columns 11, and avoid the swaying phenomenon of the longitudinal support columns 11 after being affected by the wind.

[0037] like Fig.11 As shown, in order to ensure that the annular structure display stand can display the advertising content normally and prevent the cover plate 32 from arbitrarily rotating to adjust the direction of a single phoenix sign, rotating blocks are extended at both ends of the lamp holder 31, and the edges of the opposite side walls of the bottom plate 2 and the top plate 21 are provided with rotating grooves that are rotatably plugged with the upper and lower rotating blocks. A torsion spring 34 is sleeved on the outer wall of the rotating block, and one end of the torsion spring 34 is fixedly plugged with the inner wall of the rotating groove, and the other end is fixedly plugged with the side wall of the end of the lamp holder 31. In the absence of wind or a breeze, the torsional potential energy of the torsion spring 34 can resist the blowing of the breeze, thereby preventing the rotating block from arbitrarily rotating in the rotating groove, and then preventing the light sign from arbitrarily changing its direction and affecting the display of the advertising content. It should be particularly noted that the lamp holder 31 is made of stainless steel and has a strong supporting strength. In this way, it can have sufficient supporting strength to support the cover plate 32 and the lampshade 3 assembled together. The sealing plate 32 and the lampshade 3 are rotated with the lamp holder 31 as the rotation center to adjust the direction of the entire lamp sign, so as to prevent the lamp holder 31 from cracking or breaking due to poor supporting strength when encountering strong winds, and eventually cracking and causing the lamp sign to be blown off.

[0038] In real life, billboards still need to be reinforced and protected in advance under extreme weather conditions, such as typhoons and heavy rains. If the wind is strong and exceeds the strength limit of the supporting structure, the supporting structure will crack or break directly, causing safety accidents such as falling from a high altitude and injuring passers-by or vehicles, posing a safety risk.

[0039] For this reason, Figure 4 , Figure 6 and Fig.10As shown, a transmission column 23 is rotatably inserted on the upper end surface of the chassis 2, and a hollow sleeve 24 coaxially distributed with the transmission column 23 is fixed on the upper end surface of the chassis 2. A plurality of adjustment notches are provided on the side wall of the bottom end of the hollow sleeve 24, and a latch 262 fixedly connected to the upper end surface of the chassis 2 is fixed on the top wall in the adjustment notch. A pull rod 26 radially distributed along the hollow sleeve 24 is slidably sleeved on the outer wall of the latch 262, and a closing plate 32 is rotatably set on the opposite side walls of the top plate 21 and the chassis 2, one end of the pull rod 26 is located in the hollow sleeve 24, and the other end is hinged to the side wall of the closing plate 32 of the light sign near the edge.

[0040] For example, if you encounter Fig.10 When there is a strong wind in the direction indicated by arrow A, the outer wall of the lampshade 3 serves as the wind-receiving surface and is blown by the strong wind, so that the lampshade 3 and the cover plate 32 have an external force to flip around the lamp holder 31. At this time, the cover plate 32 flips accordingly and drives the hinged pull rod 26 to push in the direction of the wind, so that the pull rod 26 slides along the outer wall of the pin 262 and further pushes toward the center of the hollow sleeve 24, creating an exhaust gap between two adjacent light billboards, thereby reducing the wind-receiving surface of the light billboard wall and effectively protecting the billboard from damage.

[0041] Furthermore, a hollow limit seat 25 capable of lifting and lowering adjustment is also provided in the hollow sleeve 24. When the hollow limit seat 25 is located on the upper end surfaces of the plurality of pull rods 26, the position of the pull rods 26 can be limited. When the hollow limit seat 25 is adjusted upward, it can be separated from the upper end surfaces of the pull rods 26. Specifically, the upper end of the transmission column 23 rotates and extends out of the top plate 21 and is fixedly connected to a plurality of fan blades 22. A plurality of pull sleeves 27 are fixed to the radial side walls of the transmission column 23. The pull sleeves 27 are provided with T-slots, and a push rod 271 with a T-shaped structure is slidably inserted in the T-slots. Figure 7 As shown, the inner radial side wall of the hollow limit seat 25 is a truncated cone-shaped hollow structure that is small at the top and large at the bottom, and the bottom end of the inner radial side wall of the hollow limit seat 25 extends obliquely to the bottom end of the radial side wall of the hollow limit seat 25. When the fan blades 22 are blown laterally, rotational power is generated, driving the transmission column 23 to rotate synchronously. The pull sleeve 27 and the push rod 271 rotate synchronously with the transmission column 23 to generate centrifugal force. The end of the push rod 271 extends out of the T-slot. After the end of the push rod 271 extends out of the T-slot, it fits with the inner radial side wall of the hollow limit seat 25. The faster the fan blades 22 rotate when blown by strong wind, the greater the centrifugal force generated by the rotation of the pull sleeve 27 and the push rod 271. Then, the greater the centrifugal force of the push rod 271 sliding outward along the T-slot, the larger the radius of the annular structure formed by the rotation of multiple push rods 271. Therefore, during the rotation of the inner wall of the truncated cone-shaped hollow structure of the hollow limit seat 25, the hollow limit seat 25 can be gradually lifted and adjusted upward and disengaged from the pull rod 26, thereby not affecting the rotation and adjustment of the light board around the lamp holder 31 to avoid being blown by strong wind.

[0042] When there is no wind, the light board is subjected to the torque of the torsion spring 34 and rotates in the opposite direction to reset. At the same time, the pull sleeve 27 and the push rod 271 lose the centrifugal force, and the hollow limit seat 25 falls under its own weight and presses on one end of the multiple pull rods 26 located in the hollow sleeve 24. In addition, multiple positioning teeth are provided at the bottom end of the hollow limit seat 25, and multiple positioning grooves 261 are provided on the upper side wall of one end of the pull rod 26 located in the hollow sleeve 24. Figure 5 and Figure 6 As shown, when the hollow limit seat 25 falls back into the hollow sleeve 24 and presses on the upper end surfaces of the multiple tie rods 26, the positioning tooth block can be embedded in the positioning groove 261 of the corresponding position, firstly, the tie rod 26 is prevented from pulling the sealing plate 32 to rotate around the lamp holder 31, and secondly, the assembly tie rod 26 can swing around the latch 262 as the center, causing the sealing plate 32 to rotate around the lamp holder 31, affecting the correct orientation of the light board, and further affecting the effective display of the advertisement. When the position of the tie rod 26 is limited, the multiple light boards form a ring-shaped structure display frame again for advertising display.

[0043] Further, such as Figure 7 As shown, the inner diameter of the upper opening of the truncated cone-shaped hollow structure is set to be equal to the outer diameter of the transmission column 23. The purpose of this design is that during the lifting process of the hollow limit seat 25, the inner side wall of the upper opening of the truncated cone-shaped hollow structure is always in contact with the radial outer wall of the transmission column 23, which can avoid shaking. Figure 8 As shown, a rolling sleeve is rotatably connected to the end of the push rod 271, and the rolling sleeve can replace the end of the push rod 271 to contact the inner radial side wall of the hollow limit seat 25, so that during the rotation of the push rod 271, the rolling sleeve rolls along the inner radial side wall of the hollow limit seat 25 to reduce the friction resistance during contact.

[0044] The above structure can adjust the direction of the light board after being blown by strong winds to reduce the wind-exposed area without setting up electric component adjustment operations, thereby effectively protecting the billboard from being damaged.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
