Movable adjustable advertising sign

Abstract

This application discloses a movable and adjustable advertising signboard, which includes: a support base, the upper end of which is fixedly connected to the back of the electronic advertising signboard; a cable shielding component; and an intermittent cable lifting component. To address the problem in existing mobile electronic advertising signs where cables easily roll into the bottom wheels and become entangled during movement, especially when turning, this application designs a cable shielding component. This component blocks the cables, reducing the likelihood of them rolling into the wheels. Simultaneously, an intermittent cable lifting component drives the cables to move up and down, intermittently detaching them from the ground, further reducing the risk of them being crushed or tangled by the wheels. This design is particularly suitable for advertising signs that require frequent movement.

Description

Technical Field

[0001] This application relates to the field of electronic billboard technology, and in particular to movable and adjustable advertising signs. Background Technology

[0002] Electronic advertising signs are a common type of advertising and promotional equipment. In some common scenarios, there is a need to move and adjust the position of the signs. In commercial promotional activities, the positions of signs in areas such as shopping mall atriums and supermarket entrances need to be dynamically adjusted according to the promotional theme. Mobile electronic billboards typically require cables for connection. When the billboard moves or turns, the bottom cable, lacking effective restraint, is prone to rolling into the gap between the wheel and the ground, causing entanglement or even mechanical failure. At the same time, the cable is in constant contact with the ground and is easily crushed by the wheel during frequent movement, accelerating the risk of cable sheath damage and internal breakage. These problems are particularly prominent in places such as shopping malls and exhibitions where the billboard position needs to be frequently adjusted, directly affecting the equipment's mobility and service life. In other words, existing technologies have the following technical problems: when ordinary electronic billboards are moved frequently, the cables are prone to rolling into the wheels and becoming tangled. Therefore, a movable and adjustable advertising sign is proposed to address the above problems. Summary of the Invention

[0023] Please see Figure 1-4 As shown, the movable and adjustable advertising signboard includes: A support base 1 is provided, with casters 2 installed on the bottom surface of the support base 1. A support frame 4 is fixedly connected to the upper surface of the support base 1, and the upper end of the support frame 4 is fixedly connected to the back of the electronic billboard 3. Cable shielding component 5 is fixedly installed on the side of the support base 1. The cable shielding component 5 is used to prevent the cable from rolling into the caster wheel 2. Intermittent lifting cable assembly 6 is installed on the support frame 4 and is used to intermittently lift the connecting cable 301.

[0024] Through the above technical solution, the cable shielding component 5 can block the cable and reduce the phenomenon of the cable rolling into the wheel. At the same time, the intermittent cable lifting component 6 is set. The intermittent cable lifting component 6 can drive the cable to move up and down, so that the cable is intermittently separated from the ground, thereby further reducing the phenomenon of being crushed or caught by the wheel. It is especially suitable for billboards that need to be moved frequently. A connecting cable 301 is connected to the back of the electronic billboard 3.

[0025] The cable shielding assembly 5 includes a fixed bracket 501 and a rubber curtain 502. Several cable shielding assemblies 5 are provided, and several cable shielding assemblies 5 are respectively fixed at the side of the caster wheel 2. Several rubber curtains 502 are fixedly connected to the bottom surface of the fixed bracket 501. The bottom ends of the rubber curtains 502 contact the ground and are arranged in a ring around the caster 2. Through this technical solution, the arrangement of several rubber curtains 502 can effectively block cables. When cables approach the caster 2, they are blocked by the rubber curtains 502. At the same time, the rubber curtains 502 do not hinder the normal movement of the device, making it particularly suitable for billboards that need to be moved frequently. Furthermore, the rubber curtain 502 adopts a flexible rubber structure, and the spacing between adjacent curtains is 5-10cm; The intermittent lifting assembly 6 includes a fixed bracket 602, a lifting frame 603, a connecting rod 604, a connecting sleeve 605, and a reciprocating lifting unit. The fixed bracket 602 is fixedly installed on the side wall of the support frame 4, and the lifting frame 603 is rotatably connected to the fixed bracket 602. One end of a connecting rod 604 is fixedly connected to the bottom end of the lifting frame 603, and a connecting sleeve 605 is fixedly connected to the other end of the connecting rod 604. The connecting cable 301 passes through the connecting sleeve 605 and is fixed to the connecting sleeve 605; The reciprocating lifting unit includes a servo motor 601, a moving plate 606, a support frame 607, a moving slider 608, a rotating disk 609, a connecting rod 610, and a connecting leg 611. The servo motor 601 is fixedly installed on the outer wall of the support frame 4. The support frame 4 has an inner cavity, and the rotating disk 609 is rotatably connected to the inner cavity of the support frame 4. Through this technical solution, the servo motor 601 can drive the rotating disk 609 to rotate; the servo motor 601 drives the connecting rod 610 through the rotating disk 609 to achieve reciprocating motion. The rotation axis of the rotary disk 609 is coaxially connected to the output shaft of the servo motor 601.

[0026] The reciprocating lifting unit is equipped with a movable slider 608, which is hinged to the connecting rod 610 via a connecting leg 611. The movable slider 608 is slidably connected in the inner cavity of the support frame 4. The connecting leg 611 is fixedly connected to the bottom end of the movable slider 608. One end of the connecting rod 610 is rotatably connected to the bottom end of the connecting leg 611. The other end of the connecting rod 610 extends to the side wall of the rotating disk 609 and is rotatably connected to the rotating disk 609. Through this technical solution, the rotation of the rotating disk 609 can drive the bottom end of the connecting rod 610 to move in a ring, thereby driving the movable slider 608 to perform linear reciprocating motion in the inner cavity of the support frame 4. The movable slider 608 is connected to the movable plate 606, and the movable plate 606 forms a transmission mechanism with the lifting frame 603 through the support frame 607. The movable plate 606 is disposed on the side wall of the support frame 4 and slides with the support frame 4. The movable plate 606 is fixedly connected to the movable slider 608. One end of the support frame 607 is rotatably connected to the movable plate 606, and the other end of the support frame 607 is rotatably connected to the side wall of the lifting frame 603. Through this technical solution, when the movable slider 608 performs linear reciprocating motion, it can drive the movable plate 606 to perform up-and-down reciprocating motion, thereby driving the lifting frame 603 to perform reciprocating swing through the support frame 607, thereby driving the connecting sleeve plate 605 to perform up-and-down reciprocating swing, thereby intermittently lifting the connecting cable 301. Through intermittent lifting, the cable can form a "wavy" path, keeping the cable intermittently detached from the ground, reducing the risk of getting caught in the wheel. At the same time, the wavy cable trajectory formed by lifting can automatically eliminate the tendency of kinking when the direction of movement changes, reducing the bending stress of the cable.

[0027] Preferably, the lifting frequency of the intermittent lifting wire assembly 6 is set to 0.5-2Hz, and the lifting amplitude is 10-30cm.

[0028] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
