Description

Technical Field

[0001] The present invention relates to the technical field of billboards, and in particular to a billboard with windproof and earthquake-resistant functions. Background Art

[0002] Billboards are a common outdoor advertising medium used to display brand information, promotional activities, public service announcements, etc. With the acceleration of urbanization, outdoor billboards are increasingly widely used. Existing billboards are usually installed outdoors through a mounting base, but due to the small size of the mounting base and the large size of the billboard, when there is strong wind, the center of gravity is easily unstable, causing it to tilt and collapse, which not only affects the advertising effect, but also poses a safety hazard.

[0003] Therefore, a billboard with windproof and earthquake-resistant functions has been developed that can reduce the wind-exposed area of ​​the billboard and at the same time lower the overall center of gravity of the billboard to prevent the billboard from tilting and collapsing in a windy environment. Summary of the invention

[0004] In order to overcome the disadvantages that the installation base is small and the billboard is large, when strong winds occur, the center of gravity is easily unstable, resulting in tilting and collapse, which not only affects the advertising effect but also poses a safety hazard. The present invention provides a billboard with windproof and earthquake-resistant functions that can reduce the wind-exposed area of ​​the billboard and at the same time lower the overall center of gravity of the billboard, thereby preventing the billboard from tilting and collapsing in strong winds.

[0005] A billboard with windproof and earthquake-resistant functions includes a base, a fixing frame, a connecting billboard, a guide rod, a limiting mechanism and a rotating mechanism. The fixing frame is clamped on the upper middle side of the base, and a plurality of connecting billboards are clamped on the fixing frame. A plurality of guide rods are slidably connected to the middle of the base, and the guide rods are all clamped and cooperated with the fixing frame. The base is provided with a limiting mechanism capable of limiting the fixing frame, and the fixing frame is provided with a rotating mechanism capable of rotating and retracting the connecting billboard.

[0006] Further description, it also includes a gripping block, and the guide rods are all connected with the gripping block.

[0007] Further description, the limiting mechanism includes a guide movable frame, a fixed rack, a first motor, a connecting column, a gear, an anemometer, a first spring and a photoelectric sensor. The guide movable frame is slidably connected between two vertically adjacent guide rods, and the guide movable frames are slidably connected to the base. The lower part of the guide movable frame is connected to a fixed rack, the lower side of the middle part of the base is connected to the first motor, the lower side of the first motor output shaft is connected to a connecting column, the lower side of the connecting column is connected to a gear, the fixed racks are meshed with the gears, the left and right sides of the upper part of the fixed frame are rotatably connected to the anemometer, and the guide movable frames are connected to the connected guide rods. There is a first spring, and photoelectric sensors are connected to the left and right sides of the upper part of the fixed frame. The photoelectric sensors are all facing the adjacent anemometers. The photoelectric sensors are all electrically connected to the first motor. A reflective mark is attached to the anemometer. When the anemometer is blown by the wind, the photoelectric sensor detects the change of the reflective mark on the anemometer, and then detects the rotation speed of the anemometer. When the photoelectric sensor detects that the rotation speed of the anemometer is too fast, the first motor is controlled to start, so that the connecting column and the gear rotate. At this time, the gear meshes with the fixed rack, so that the fixed rack drives the guide moving frame to approach each other and compress the first spring, so that the guide rod cannot move away from the fixed frame.

[0008] Further explanation, the rotating mechanism includes a second motor, a screw rod, a connecting movable frame, a fixed column, a connecting rod, a connecting disk, a guide gear block, a second spring and a connecting rack frame. The second motor is connected to the left side of the lower part of the fixed frame, and the photoelectric sensors are electrically connected to the second motor. The second motor output shaft is connected to a screw rod, and the screw rod is rotatably connected to the fixed frame. The fixed frame is slidably connected to multiple connecting movable frames on both sides. The first connecting movable frame on the left side from top to bottom is threadedly connected to the screw rod. The connecting billboards are rotatably connected to adjacent connecting movable frames. Fixed columns are connected to the left and right sides of the lower part of the fixed frame. The connecting billboards are rotatably connected to connecting rods on both sides. The fixed columns are also rotatably connected to connecting rods. Two adjacent connecting rods are rotatably connected. The connecting billboard is connected to a connecting disk on the left side, and multiple guide gear blocks are slidably connected to the connecting disk. The guide gear blocks are connected to the connected connecting disks. There are multiple second springs connected in between, and a connecting rack rack is connected to the left side of the fixed frame, and the guide gear block is engaged with the connecting rack rack. When the photoelectric sensor detects that the wind meter rotates too fast, the second motor is controlled to start, driving the screw rod to rotate, so that the first connecting movable frame on the left side from the top moves downward, and the remaining connecting movable frames move downward through the connecting rod, thereby driving the connecting billboard to move downward. When the connecting billboard moves downward, the guide gear block on the connecting disk engages with the connecting rack rack to move, so that the connecting disk and the connecting billboard rotate. When the connecting disk rotates, it is limited by the connected movable frame, so that the connecting disk rotates 90° from a vertical state to a horizontal state and is fixed. At this time, the connecting disk stops rotating, and the connecting movable frame continues to move downward, so that the guide gear block engaged with the connecting rack rack moves forward, and the second spring is squeezed and contracted. As the connecting movable frame moves downward, the connecting billboard is folded and stacked on the bottom of the fixed frame.

[0009] Further explanation: the connecting movable frame on the left side is provided with a limit column.

[0010] Further description, it also includes a knocking mechanism, which includes a connecting bracket, a guide knocking column, a third spring and a bell. The upper side of the anemometer is connected to a connecting bracket, and the connecting bracket is slidably connected to a guide knocking column. The third spring is connected between the guide knocking column and the connected connecting bracket. Bells are connected to the upper sides of the left and right parts of the fixed frame. When the anemometer rotates, the connecting bracket is driven to rotate, so that the guide knocking column knocks the bell under the action of the third spring, causing the bell to sound.

[0011] Further description, it also includes a prompt mechanism, which includes a connecting pillar, an impeller and a prompt light pole. The upper part of the fixed frame is rotatably connected to two left and right connecting pillars, each of which is connected to an impeller, and a prompt light pole is connected between the connecting pillars. In a strong wind environment, the rotation of the impeller drives the connecting pillar to rotate, causing the prompt light pole to rotate.

[0012] Further description is provided, and the anti-seismic mechanism includes a connecting base and a fourth spring. The lower sides of the left and right parts of the base are connected to the connecting base by a damping sliding method. A plurality of fourth springs are connected between the connecting base and the base. The connecting base is installed on the ground. When the base vibrates, the base is buffered and shock-absorbing by the force of the fourth spring.

[0013] Further description, it also includes a decoration mechanism, which includes a connecting block and a light board. The lower part of the fixed frame is connected to two left and right connecting blocks, and the light board is connected between the connecting blocks. When the billboard is connected to display the advertising content, the light board on the connecting block lights up.

[0014] Further explanation: both the front and rear parts of the connection block are provided with mounting holes.

[0015] The beneficial effects are as follows: 1. When the connected billboard moves downward, the guide tooth block on the connecting disk meshes with the connecting rack frame to move, so that the connecting disk and the connected billboard rotate. When the connecting disk rotates, it is limited by the limiting column on the connected moving frame, so that the connecting disk is fixed after rotating to a horizontal state. As the connected moving frame moves downward, the connected billboard is folded and stacked on the bottom of the fixed frame, thereby achieving the effect of reducing the wind-exposed area of ​​the billboard and at the same time lowering the overall center of gravity of the billboard, thereby preventing the billboard from tilting and collapsing in a windy environment.

[0016] 2. When the photoelectric sensor detects that the anemometer rotates too fast, the present invention controls the first motor to start, causing the connecting column and the gear to rotate. At this time, the gear meshes with the fixed rack, causing the fixed rack to drive the guide movable frame to approach each other and compress the first spring, so that the guide rod cannot move away from the fixed frame, thereby achieving the effect of further enhancing the stability of the billboard in strong wind conditions and preventing the billboard from being blown away by the wind.

[0017] 3. The present invention drives the connecting bracket to rotate while the anemometer rotates, so that the guide knocking column knocks the bell under the action of the third spring, causing the bell to ring, thereby achieving the effect of knocking reminders in a strong wind environment to alert passers-by.

[0018] 4. In the present invention, when there is a strong wind, the impeller rotates to drive the connecting pillar to rotate, so that the warning lamp column rotates, thereby achieving the effect of providing light prompts in a strong wind environment to alert passers-by.

[0019] 5. The present invention installs the connecting base on the ground. When the base vibrates, the base is buffered and shock-absorbed by the force of the fourth spring, thereby achieving the effect of being able to resist earthquakes on the base and avoid damage to the billboard.

[0020] 6. When the present invention displays the advertisement content by connecting the billboards, the light panels on the connecting blocks light up, thereby attracting the attention of pedestrians and improving the advertisement display effect. BRIEF DESCRIPTION OF THE DRAWINGS

The lower part of the guide movable frame 60 is connected to the fixed rack 61, the lower side of the middle part of the base 1 is connected, the lower side of the output shaft of the first motor 62 is connected to the connecting column 63, and the lower side of the connecting column 63 is connected to the gear 64. The fixed rack 61 is meshed with the gear 64, and the anemometer 65 is rotatably connected to the left and right sides of the upper part of the fixed frame 2. The first spring 66 is connected between the guide movable frame 60 and the connected guide rod 4, and the photoelectric sensor 67 is connected to the left and right sides of the upper part of the fixed frame 2. The photoelectric sensor 67 is facing the adjacent anemometer 65, and the photoelectric sensor 67 is electrically connected to the first motor 62.

[0035] like Figure 1 , Figure 5 , Figure 6 and Figure 7As shown, the rotating mechanism 7 includes a second motor 70, a screw rod 71, a connecting movable frame 72, a fixed column 73, a connecting rod 74, a connecting plate 75, a guide tooth block 76, a second spring 77 and a connecting rack frame 78. The second motor 70 is connected to the left side of the lower part of the fixed frame 2, and the photoelectric sensors 67 are electrically connected to the second motor 70. The screw rod 71 is connected to the output shaft of the second motor 70, and the screw rod 71 is rotatably connected to the fixed frame 2. Nine connecting movable frames 72 are slidably connected to the left and right sides of the fixed frame 2. The first connecting movable frame 72 from the top to the bottom on the left side is threadedly connected to the screw rod 71, and the connecting billboards 3 are all rotatably connected to the adjacent connecting movable frames 72. The fixed frame 2 is connected in a manner that fixed columns 73 are connected to the left and right sides of the lower part of the fixed frame 2, and connecting rods 74 are rotatably connected to the left and right sides of the connecting billboard 3. The fixed columns 73 are also rotatably connected to connecting rods 74, and two adjacent connecting rods 74 are rotatably connected. A connecting disk 75 is connected to the left part of the connecting billboard 3, and a limiting column is provided on the connecting movable frame 72 on the left side to facilitate limiting the connecting disk 75. A plurality of guide gear blocks 76 are slidably connected to the connecting disk 75, and two second springs 77 are connected between the guide gear blocks 76 and the connected connecting disks 75. A connecting rack frame 78 is connected to the left side of the fixed frame 2, and the guide gear blocks 76 are meshed with the connecting rack frame 78.

[0036] When using the present invention, first install the base 1 in the billboard display area, then hold the gripping block 5, pull the guide rods 4 away from each other, then snap-fit ​​the fixing frame 2 with the base 1, then push the guide rod 4 to reset and snap-fit ​​with the fixing frame 2, so that the connected billboard 3 is fixed at this position to display the advertising content, when the guide rods 4 are pulled away from each other, the first spring 66 is squeezed and contracted, and when the guide rod 4 is reset and snap-fit ​​with the fixing frame 2, the first spring 66 rebounds, and when displaying the advertisement, a reflective mark is attached to the anemometer 65, and when the anemometer 65 is blown by the wind, the photoelectric sensor The sensor 67 detects the change of the reflective mark on the anemometer 65, and then detects the rotation speed of the anemometer 65. When the photoelectric sensor 67 detects that the rotation speed of the anemometer 65 is too fast, it controls the first motor 62 to start, so that the connecting column 63 and the gear 64 rotate. At this time, the gear 64 meshes with the fixed rack 61, so that the fixed rack 61 drives the guide movable frame 60 to move closer to each other and compress the first spring 66, so that the guide rod 4 cannot move away from the fixed frame 2, thereby playing a role in locking the fixed frame 2 in the case of strong wind and preventing the fixed frame 2 from separating from the base 1. When the photoelectric sensor 67 detects that the wind meter 65 rotates too fast, the second motor 70 is controlled to start, driving the screw rod 71 to rotate, so that the first connecting movable frame 72 on the left side from the top moves downward, and the remaining connecting movable frames 72 move downward through the connecting rod 74, thereby driving the connecting billboard 3 to move downward. When the connecting billboard 3 moves downward, the guide tooth block 76 on the connecting disk 75 meshes with the connecting rack frame 78, so that the connecting disk 75 and the connecting billboard 3 rotate. When the connecting disk 75 rotates, the guide tooth block 76 on the connecting rack frame 72 is engaged with the connecting rack frame 78. The limiting column limits the connection plate 75 to rotate 90° from a vertical state to a horizontal state and then be fixed. At this time, the connection plate 75 stops rotating, and the connecting movable frame 72 continues to move downward, so that the guide tooth block 76 engaged with the connecting rack frame 78 moves forward, and the second spring 77 is squeezed and contracted. As the connecting movable frame 72 moves downward, the connected billboard 3 is folded and stacked on the bottom of the fixed frame 2, thereby reducing the wind-exposed area of ​​the billboard and lowering the overall center of gravity of the billboard, thereby preventing the billboard from tilting and collapsing in a windy environment.

[0037] like Figure 1 and Figure 8 As shown, it also includes a knocking mechanism 8, which includes a connecting bracket 80, a guide knocking column 81, a third spring 82 and a bell 83.

The third spring 82 is connected between the guide knocking column 81 and the connected connecting bracket 80, and the upper sides of the left and right parts of the fixing frame 2 are connected to the bell 83.

[0038] The knocking mechanism 8 of the device can be used to give knocking reminders. When the anemometer 65 rotates, the connecting bracket 80 is driven to rotate, so that the guide knocking column 81 knocks the bell 83 under the action of the third spring 82, causing the bell 83 to ring, thereby providing knocking reminders in a windy environment and alerting passers-by.

[0039] like Figure 1 and Figure 8 As shown, a prompt mechanism 9 is also included, which includes a connecting support 90, an impeller 91 and a prompt light column 92. The upper part of the fixed frame 2 is rotatably connected to two left and right connecting supports 90, each of which is connected to the impeller 91, and the prompt light columns 92 are connected between the connecting supports 90.

[0040] By using the prompt mechanism 9 of the device, light prompts can be given. When the billboard 3 is connected to display the advertising content, the prompt light column 92 lights up. In a windy environment, the impeller 91 rotates to drive the connecting support 90 to rotate, causing the prompt light column 92 to rotate, thereby providing light prompts in a windy environment to alert passers-by.

[0041] like Figure 1 and Fig. 9 As shown, it also includes an anti-seismic mechanism 10, which includes a connecting base frame 100 and a fourth spring 101. The lower sides of the left and right parts of the base 1 are connected to the connecting base frame 100 through a damping sliding type, and two fourth springs 101 are connected between the connecting base frame 100 and the base 1.

[0042] By using the anti-seismic mechanism 10 of the device, the base 1 can be anti-seismic. The connecting base frame 100 is installed on the ground. When the base 1 vibrates, the base 1 is buffered and shock-absorbed by the force of the fourth spring 101, thereby playing a role in anti-seismic protection of the base 1 and avoiding damage to the billboard.

[0043] like Figure 1 and Fig.10 As shown, a decoration mechanism 11 is also included, which includes a connecting block 110 and a lighting panel 111. The lower part of the fixing frame 2 is connected to two left and right connecting blocks 110. The front and rear parts of the connecting blocks 110 are provided with mounting holes for easy installation on the ground. The lighting panels 111 are connected between the connecting blocks 110.

[0044] The decorative mechanism 11 of the device can improve the advertising display effect. When the billboard 3 is connected to display the advertising content, the light panel 111 on the connecting block 110 lights up, thereby attracting the attention of pedestrians and improving the advertising display effect.
