Description

Technical Field

[0001] This utility model relates to the field of billboard technology, specifically to a structure that facilitates the hanging of billboards. Background Technology

[0002] Billboards refer to all outdoor media that convey advertising information, and are typically constructed from welded materials such as square tubing, angle steel, and steel plates. Their function is to display advertising information, and they are widely used in commercial activities and daily life, possessing significant visual impact and communication effectiveness.

[0003] According to a search, Chinese patent document, publication number CN220731140U, discloses a hanging billboard that is easy to install. By rotating the compensation block to the higher side of the billboard, the weight of that side is compensated, which can easily adjust the horizontal level of the rope-hanging billboard and improve the installation efficiency.

[0004] However, the length of the hanging ropes on the aforementioned billboards is fixed, which means that the height at which the billboard itself is suspended cannot be adjusted, making it impossible to adjust it according to the needs of the scene. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a structure for easy hanging of billboards, which has the advantages of easy installation and adjustable hanging height of the billboard body to meet users' different hanging height requirements of the billboard, thus solving the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a structure for facilitating the hanging of billboards, comprising a billboard body, an ear block fixedly connected to the back of the billboard body, a rotating rod fixedly connected to the outer surface of the ear block, a worm gear fixedly connected to the outer surface of the rotating rod, and bases rotatably connected to both ends of the rotating rod. A first knob is rotatably connected to the top surface of the base, a worm gear is fixedly connected to the bottom end of the first knob, a rope connector is fixedly connected to the top of the base, a steel wire rope is fixedly connected inside the rope connector, a winding rod is wound around one end of the steel wire rope, a turntable is fixedly connected to the top and bottom of the winding rod, a second knob is fixedly connected to the center of the end face of the turntable located at the bottom end of the winding rod, a ratchet is fixedly connected to the outer surface of the second knob, a sliding wheel is slidably contacted to the outer surface of the steel wire rope, a fixed seat is connected to the bottom of the sliding wheel by a screw, a pawl is rotatably connected to the lower surface of the fixed seat, and an arc-shaped spring plate is connected to the lower surface of the fixed seat by a pin.

[0007] Preferably, each side of the base is rotatably connected to two ear blocks via a rotating rod, and the billboard body has two such blocks, with two ear blocks fixedly connected to the back of each of the two billboard bodies.

[0008] By employing the above technical solution, and distributing two billboard bodies in two directions, people can see the advertising content from both sides. Furthermore, the two billboard bodies share a single mounting base and steel cable, thus saving on materials.

[0009] Preferably, a worm gear is fixedly connected to the middle section of the outer surface of the rotating rod, and the worm gear transmission connects two worm gears, with the two worm gears symmetrically arranged around the axis of the worm.

[0010] Through the above technical solution, turning knob number one drives the worm gear to rotate, which in turn drives two worm wheels to rotate. These worm wheels then drive a connected rotating rod to rotate, which in turn drives two lugs, which in turn drive the billboard body to rotate. This allows for adjustment of the billboard body's angle, and the angles of both billboard bodies can be adjusted simultaneously. Since different installation environments have different requirements for the billboard's display effect, this adjustable suspension angle design allows the billboard body to flexibly adapt to various installation environments.

[0011] Preferably, the lower surface of the fixing base has a through hole through which a steel wire rope can pass, and two sliding wheels are installed on the inner bottom surface of the fixing base.

[0012] Using the above technical solution, turning knob number two clockwise rotates the turntable, which in turn rotates the winding rod, thus winding up the steel wire rope. This increases the suspension height of the billboard. Conversely, turning knob number two counterclockwise releases the steel wire rope, thus lowering the suspension height of the billboard. This allows for adjustment of the billboard's height according to the installation environment. By optimizing the billboard's position, it ensures that more pedestrians can notice the advertising content, increasing the advertisement's exposure.

[0013] Preferably, a straight groove is formed through the curved surface of the winding rod, and a steel wire rope is inserted into the straight groove. A handle is fixedly connected to the outer surface of both the first knob and the second knob.

[0014] Preferably, one side of the arc-shaped spring sheet is connected to the outer surface of the pawl by a screw, and the pawl mechanically engages with the ratchet.

[0015] With the above technical solution, turning the second knob can also drive the ratchet to rotate. When the ratchet rotates clockwise, the pawl will not block the ratchet; the pawl will only restrict the ratchet from rotating in the opposite direction. In this way, after the length of the steel wire rope is adjusted, the billboard body will not fall automatically due to gravity. Conversely, when it is necessary to lower the height of the billboard body, the arc-shaped spring plate can be moved to make the pawl disengage from the ratchet. At this time, the ratchet can rotate in the opposite direction, thereby lowering the billboard body.

[0016] Compared with the prior art, the present invention provides a structure for easy hanging of billboards, which has the following advantages:

[0017] 1. This utility model features a clever design that combines a rotating rod with a worm gear and a worm. Rotating the first knob drives the worm, which in turn rotates the two worm gears, thereby synchronously adjusting the angles of the two billboard bodies. This design allows for flexible adaptation to different installation environments and enhances the practicality and adaptability of the billboard. It can be easily installed and used in various scenarios, ensuring optimal advertising display effects.

[0018] 2. This utility model allows the winding rod to wind up the steel wire rope by rotating the No. 2 knob clockwise, increasing the suspension height of the billboard; rotating it counterclockwise releases the steel wire rope and lowers the height. This allows for flexible adjustment of the billboard's position according to the installation environment, ensuring that more pedestrians notice the advertising content and increasing advertising exposure. The mechanical cooperation between the ratchet and pawl, after adjusting the steel wire rope length, restricts the ratchet from rotating in the opposite direction, preventing the billboard from falling automatically due to gravity, thus ensuring the stability and safety of the billboard suspension.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] Please see Figures 1-5 A structure for facilitating the hanging of billboards includes a billboard body 1. A lug 2 is fixedly connected to the back of the billboard body 1. A rotating rod 3 is fixedly connected to the outer surface of the lug 2. A worm gear 4 is fixedly connected to the outer surface of the rotating rod 3. Bases 5 are rotatably connected to both ends of the rotating rod 3. A knob 6 is rotatably connected to the top surface of the base 5. A worm gear 7 is fixedly connected to the bottom end of the knob 6. A rope connector 8 is fixedly connected to the top of the base 5. A steel wire rope 9 is fixedly connected inside the rope connector 8. One end of the steel wire rope 9 is wound with... A winding rod 10 is attached, and a turntable 11 is fixedly connected to the top and bottom of the winding rod 10. A second knob 12 is fixedly connected to the center of the end face of the turntable 11 located at the bottom of the winding rod 10. A ratchet 13 is fixedly connected to the outer surface of the second knob 12. A sliding wheel 14 is slidably contacted on the outer surface of the wire rope 9. A fixed seat 15 is connected to the bottom of the sliding wheel 14 by screws. A pawl 16 is rotatably connected to the lower surface of the fixed seat 15, and an arc-shaped spring plate 17 is connected to the lower surface of the fixed seat 15 by a pin.

[0027] Specifically, two ear blocks 2 are rotatably connected to both sides of the base 5 via rotating rods 3. Two billboard bodies 1 are provided, and two ear blocks 2 are fixedly connected to the back of each billboard body 1. The advantage is that by distributing the two billboard bodies 1 in two directions, people can see the advertising content from both directions. Furthermore, the two billboard bodies 1 share a single fixing base 15 and steel wire rope 9, saving on materials.

[0028] Specifically, a worm gear 4 is fixedly connected to the middle section of the outer surface of the rotating rod 3. The worm 7 is connected to two worm gears 4, and the two worm gears 4 are symmetrically arranged around the axis of the worm 7. The advantage is that when the first knob 6 is turned, the worm 7 is driven to rotate. After the worm 7 rotates, it drives the two worm gears 4 to rotate. The two worm gears 4 drive the rotating rod 3 connected to them to rotate. The rotating rod 3 then drives the two lugs 2, and the lugs 2 drive the billboard body 1 to rotate. In this way, the angle of the billboard body 1 can be adjusted, and the angles of two billboard bodies 1 can be adjusted simultaneously. Since different installation environments have different requirements for the display effect of the billboard, the design of adjusting the suspension angle allows the billboard body 1 to flexibly adapt to various installation environments.

[0029] Specifically, the lower surface of the fixing base 15 has a through hole through which the steel wire rope 9 can pass, and two sliding wheels 14 are installed on the inner bottom surface of the fixing base 15. The advantage is that when the second knob 12 is turned clockwise, it drives the turntable 11 to rotate, which in turn drives the winding rod 10 to rotate, thus winding the steel wire rope 9. This increases the suspension height of the billboard body 1. Conversely, when the second knob 12 is turned counterclockwise, the steel wire rope 9 is released, thus lowering the suspension height of the billboard body 1. This allows the height of the billboard body 1 to be adjusted according to the installation environment. By optimizing the position of the billboard body 1, it ensures that more pedestrians can notice the advertising content, increasing the exposure of the advertisement.

[0030] Specifically, a straight groove is cut through the curved surface of the winding rod 10, and a steel wire rope 9 is inserted into the groove. A handle is fixedly connected to the outer surface of both the first knob 6 and the second knob 12. One side of the arc-shaped spring plate 17 is connected to the outer surface of the pawl 16 by a screw, and the pawl 16 mechanically engages with the ratchet 13. The advantage is that when the second knob 12 is turned, it also drives the ratchet 13 to rotate. When the ratchet 13 rotates clockwise, the pawl 16 does not obstruct the ratchet 13; it only restricts the ratchet 13 from rotating in the opposite direction. Thus, after the length of the steel wire rope 9 is adjusted, the billboard body 1 will not automatically fall due to gravity. Conversely, when it is necessary to lower the height of the billboard body 1, the arc-shaped spring plate 17 can be moved to disengage the pawl 16 from the ratchet 13, allowing the ratchet 13 to rotate in the opposite direction, thereby lowering the billboard body 1.

[0031] In use, firstly, the mounting base 15 can be fixed to the ceiling using expansion bolts through the mounting holes on the mounting base 15. Then, by turning knob 6, the worm gear 7 is rotated, which in turn drives the two symmetrically arranged worm wheels 4 to rotate. The worm wheels 4 drive the rotating rod 3 to rotate, and the rotating rod 3 drives the two billboard bodies 1 to rotate through the lugs 2, thereby adjusting the angle of the billboard bodies 1 to adapt to different installation environments. Secondly, turning knob 12 clockwise drives the turntable 11 to rotate, and the turntable 11 drives... Rotating the winding lever 10 winds up the wire rope 9, increasing the suspension height of the billboard body 1. Rotating it counterclockwise releases the wire rope 9, lowering the suspension height. When the second knob 12 is rotated, it drives the ratchet 13 to rotate. When the ratchet 13 rotates clockwise, the pawl 16 does not obstruct it. After adjusting the length of the wire rope 9, the pawl 16 restricts the ratchet 13 to rotate in the opposite direction to prevent the billboard body 1 from falling automatically. To lower the height of the billboard body 1, the arc-shaped spring plate 17 is moved to disengage the pawl 16 from the ratchet 13, thus lowering the height.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
