Description

Technical Field

[0001] The utility model relates to the technical field of billboards, and specifically relates to a windproof and anti - falling billboard. Background Art

[0002] A billboard is a device used to convey advertising information to the public. According to different needs, it can be made into various forms. Conventional billboards are fixed on the ground or on the wall; for relatively open places, billboards need to be fixed on the ground. However, because the billboard is very flat, when encountering strong wind weather, billboards whose bases are not fixed on the ground or wall are easily blown down by the wind.

[0003] According to the search, the Chinese patent document, publication number: CN218497760U, discloses a windproof billboard. Through the cooperation between a rectangular plate, a first windproof mechanism and a second windproof mechanism, when the billboard main body is subjected to a large wind force in the front - back direction, the billboard main body will rotate and tilt to divert the wind, thereby reducing the resistance of the billboard main body to the wind. When the billboard main body is subjected to a large wind force in the left - right direction, the billboard main body will slide along the rectangular plate and buffer the wind force, thereby preventing the wind from blowing the billboard damaged or down. However, in the actual use process, because the reset spring and the hydraulic damper are fixedly connected between the right - angled plate and the rectangular frame, it is impossible to make the billboard rotate and tilt in the front - back direction to divert the wind. The overall structure has an unobvious wind - resistance effect, and the structure is complex, which is not conducive to popularization and use. Content of the Utility Model

[0004] (1) Technical Problems to be Solved

[0005] Aiming at the deficiencies of the prior art, the utility model provides a windproof and anti - falling billboard, which has the advantages of windproof and anti - falling, and is convenient for replacing the inner page of the billboard, etc., and solves the above - mentioned technical problems.

[0006] (2) Technical Solutions

[0007] To achieve the above object, the utility model provides the following technical solution: A windproof and anti - falling billboard, including a base, the top surface of the base is fixedly connected with a sleeve, a spring rod is inserted into the sleeve, the top of the spring rod is inserted into an insertion tube, the top of the insertion tube is fixedly connected with a frame, a rotating rod is rotatably connected to the inner wall of the frame, the top of the rotating rod is fixedly connected with a sign body, and a concentric ring is fixedly connected to the outer surface of the rotating rod. A plurality of paddles are circumferentially arranged around the axis of the outer surface of the concentric ring. A pin rod is fixedly connected to the inner wall of the frame, a torsion spring is wound around the outer surface of the pin rod, and a stop piece is rotatably connected to the outer surface of the pin rod. A rectangular through - hole is opened on one side of the sign body, a cover plate covers the rectangular through - hole, a thin rod is fixedly connected to the inner side of the cover plate, and a compression spring is sleeved on the outer surface of the thin rod.

[0008] Preferably, the interior of the base is hollow, and a water inlet is provided on the top of the base, and a sealing plug is inserted into the water inlet.

[0009] Through the above technical solution, by opening the sealing plug, tap water can be poured into the water inlet of the base. The tap water fills the inside of the base to increase the weight of the base, so that the weight of the billboard can be increased when it is placed, playing a certain wind resistance role.

[0010] Preferably, the outer surfaces of the sleeve and the insertion tube are threadedly connected to a locking bolt, and two spring rods are provided.

[0011] Through the above technical solution, the spring rod can be pulled out after loosening the locking bolts on the outer surfaces of the sleeve and the insert tube, so that the base, spring rod, frame and other components can be separated, and vice versa, it is also convenient for assembly. After assembly, the spring rod plays the role of supporting the frame. When the outdoor wind is strong, even if the wind acts on the sign body, it will only cause the spring rod to bend but not fall over. In addition, the process of repeated bending and straightening of the spring rod can also make the sign body sway to attract people's attention, thereby indirectly improving the advertising effect.

[0012] Preferably, one end of the blocking piece away from the pin rod abuts against the outer surface of the paddle, one end of the torsion spring is inserted into the interior of the frame, and the other end of the torsion spring is inserted into the circular ring of the blocking piece.

[0013] Through the above technical solution, when wind acts on the sign body, since the sign body is connected to the inner wall of the frame through a rotating rod, the wind will cause the sign body to rotate, thereby unloading most of the wind force and further improving the wind resistance. The baffle contacts the paddle. When the wind force is small, the paddle on the concentric ring is limited by the baffle. Therefore, when the wind force is small, it is not enough to make the sign body rotate. Only when the wind force is large enough, the rotating force on the rotating rod and the concentric ring is large, which can make the paddle separate from the baffle. When the wind force is small, due to the provision of a base and a spring rod, it is not enough to make the sign body fall over, and the torsion spring can drive the baffle to continue to contact the paddle. The overall structure prevents the sign body from rotating when the wind force is small, thereby affecting people's viewing of the advertising content on the sign body.

[0014] Preferably, a through hole is provided on the back side of the card body, a thin rod is inserted into the through hole, and one end of the thin rod is fixedly connected to a limiting plate.

[0015] Through the above technical solution, when the cover is pushed to drive the thin rod, the thin rod compresses the compression spring, and the cover is removed from the rectangular through hole, so that the inner pages of the billboard can be placed into the body of the billboard through the rectangular through hole, and then the inner pages of the billboard can be replaced. When the cover is released, the compression spring exerts pressure on the limiting piece of the thin rod, so that the thin rod can be driven into the body of the billboard, and then the cover can be re-covered on the rectangular through hole to prevent the inner pages of the billboard inside the body from falling off.

[0016] Preferably, the sign body is surrounded by metal frames, and transparent acrylic panels are installed on the front and back of the sign body.

[0017] Through the above technical solution, two inner pages of the billboard can be placed inside the billboard body at one time, and the inner pages of the billboard can be clearly seen through the acrylic plate, thereby being able to display the advertising content more comprehensively.

[0018] Compared with the prior art, the utility model provides a windproof and anti-falling billboard, which has the following beneficial effects:

[0019] 1. When the outdoor wind is strong, the utility model acts on the sign body, and the rotational force exerted on the rotating rod and the concentric ring is large, which can make the paddle separate from the blocking piece. At this time, the sign body rotates to unload most of the wind force. At the same time, the spring rod can be bent, and the overall structure can effectively avoid the sign body from tipping over, thereby improving the wind resistance of the billboard. When the wind force is relatively small, due to the provision of the base and the spring rod, it is not enough to cause the sign body to tip over, and the torsion spring can drive the blocking piece to continue to contact the paddle. The overall structure prevents the sign body from rotating when the wind force is relatively small, thereby affecting people's viewing of the advertising content on the sign body.

[0020] 2. In the utility model, when the cover plate is pushed, the thin rod is driven and the thin rod compresses the compression spring. At this time, the cover plate is removed from the rectangular through hole, so that the inner pages of the billboard can be put into the body of the billboard through the rectangular through hole, and then the inner pages of the billboard can be replaced. When the cover plate is loosened, the compression spring exerts pressure on the limit piece of the thin rod, so that the thin rod can be driven into the body of the billboard, and then the cover plate can be re-covered on the rectangular through hole to prevent the inner pages of the billboard inside the body from falling off.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-6 , a windproof and anti - toppling billboard, including a base 1, the top surface of the base 1 is fixedly connected with a sleeve 2, a spring rod 3 is inserted into the sleeve 2, the top end of the spring rod 3 is inserted into an insertion tube 4, the top end of the insertion tube 4 is fixedly connected with a frame 5, a rotating rod 6 is rotatably connected to the inner wall of the frame 5, the top end of the rotating rod 6 is fixedly connected with a sign body 7, and a concentric ring 8 is fixedly connected to the outer surface of the rotating rod 6. A plurality of paddles 9 are circumferentially arranged around the axis on the outer surface of the concentric ring 8. A pin rod 10 is fixedly connected to the inner wall of the frame 5, a torsion spring 11 is wound around the outer surface of the pin rod 10, and a stop piece 12 is rotatably connected to the outer surface of the pin rod 10. A rectangular through hole 13 is opened on one side of the sign body 7, a cover plate 14 covers the rectangular through hole 13, a thin rod 15 is fixedly connected to the inner side of the cover plate 14, and a compression spring 16 is sleeved on the outer surface of the thin rod 15.

[0030] Specifically, the inside of the base 1 is hollow, and a water injection port is opened at the top of the base 1, and a sealing plug 17 is inserted into the water injection port. The advantage is that by opening the sealing plug 17, tap water can be poured into the water injection port of the base 1. The tap water fills the inside of the base 1 to increase the weight of the base 1, so that the billboard can increase its weight when placed, playing a certain role in wind resistance.

[0031] Specifically, locking bolts are thread - connected to the outer surfaces of the sleeve 2 and the insertion tube 4, and there are two spring rods 3. The advantage is that when the locking bolts on the outer surfaces of the sleeve 2 and the insertion tube 4 are loosened, the spring rods 3 can be pulled out. In this way, components such as the base 1, the spring rods 3 and the frame 5 can be separated. On the contrary, it is also convenient for assembly. After assembly, the spring rods 3 play a role in supporting the frame 5. When the outdoor wind force is large, even if the wind force acts on the sign body 7, only the spring rods 3 will bend and the billboard will not topple. Moreover, the process of the spring rods 3 bending and straightening repeatedly can also make the sign body 7 swing, playing a role in attracting people's attention and improving the advertising effect on the side.

[0032] Specifically, one end of the baffle 12 away from the pin rod 10 abuts against the outer surface of the paddle 9. One end of the torsion spring 11 is inserted into the interior of the frame 5, and the other end of the torsion spring 11 is inserted into the circular ring of the baffle 12. The advantage is that after the wind force acts on the sign body 7, since the sign body 7 is rotatably connected to the inner wall of the frame 5 through the rotating rod 6, the wind force will cause the sign body 7 to rotate on its own, thereby discharging most of the wind force and further improving the wind resistance. The baffle 12 abuts against the paddle 9. When the wind force is small, the paddle 9 on the concentric ring 8 is limited by the baffle 12. Therefore, when the wind force is small, it is not enough to cause the sign body 7 to rotate on its own. Only when the wind force is large enough, the rotating force received by the rotating rod 6 and the concentric ring 8 is large enough to make the paddle 9 disengage from the baffle 12. When the wind force is small, due to the setting of the base 1 and the spring rod 3, it is not enough to cause the sign body 7 to fall over. And the torsion spring 11 can drive the baffle 12 to continue to abut against the paddle 9. The overall structure prevents the sign body 7 from rotating on its own when the wind force is small and affecting people's viewing of the advertisement content on the sign body 7.

[0033] Specifically, a through hole is opened on the back surface of the sign body 7, and a thin rod 15 is inserted through the through hole. One end of the thin rod 15 is fixedly connected with a limiting piece. The advantage is that when the cover plate 14 is pushed to drive the thin rod 15, the thin rod 15 compresses the compression spring 16. At this time, the cover plate 14 moves away from the rectangular through hole 13. In this way, the inner page of the advertisement board can be put into the sign body 7 through the rectangular through hole 13, and then the inner page of the advertisement board can be replaced. When the cover plate 14 is released, the compression spring 16 has a pressure on the limiting piece of the thin rod 15, so it can drive the thin rod 15 into the sign body 7, and then the cover plate 14 can be made to cover the rectangular through hole 13 again to prevent the inner page of the advertisement board inside the sign body 7 from falling off.

[0034] Specifically, the four sides of the sign body 7 are metal frames, and transparent acrylic plates are installed on both the front and back surfaces of the sign body 7. The advantage is that two inner pages of the advertisement board can be placed in the sign body 7 at one time, and the inner pages of the advertisement board can be seen clearly through the acrylic plate, so that the advertisement content can be displayed more comprehensively.

[0035] During use, by opening the sealing plug 17, tap water can then be poured into the water injection port of the base 1. The tap water fills the interior of the base 1 to increase the weight of the base 1, so that the weight can be increased when the advertisement board is placed. When the outdoor wind force is strong and acts on the sign body 7, the rotating force received by the rotating rod 6 and the concentric ring 8 is large enough to make the paddle 9 disengage from the baffle 12. At this time, the sign body 7 rotates on its own to discharge most of the wind force. At the same time, the spring rod 3 can be bent, and the overall structure can effectively avoid the sign body 7 from falling over and improve the wind resistance of the advertisement board; when the cover plate 14 is pushed to drive the thin rod 15, the thin rod 15 compresses the compression spring 16. At this time, the cover plate 14 moves away from the rectangular through hole 13. In this way, the inner page of the advertisement board can be put into the sign body 7 through the rectangular through hole 13, and then the inner page of the advertisement board can be replaced.

[0036] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
