Technical Field

[0001] The utility model relates to the technical field of teleprompters, in particular to a teleprompter for broadcasting and hosting. Background Art

[0002] When the announcer is working, he or she needs to make a real-time broadcast facing the TV screen, so the teleprompter becomes an assistant to the announcer. The traditional teleprompter generally uses a screen to scroll the sentences and words to be broadcast at a certain speed. However, due to the use of only a single screen structure, when the single screen is accidentally not displayed or damaged, the teleprompter loses its function and cannot provide stable prompts for the host during the live broadcast, which is easy to cause broadcast accidents.

[0026] Furthermore, a first motor shield 45 is installed on one side of the square support tube 2 , and a second shaft hole is opened on the top surface of the first motor shield 45 to facilitate the extension of the shaft of the first motor 44 .

[0027] Furthermore, the horizontal telescopic platform 5 includes a support plate 51 installed on the top of the screw rod 31, and two parallel first slide grooves are arranged on both sides of the top surface of the support plate 51. A movable plate 52 is installed on the support plate 51, and second slide grooves are opened on both sides of the top surface of the movable plate 52 corresponding to the first slide grooves. The movable plate 52 is inserted through the first slide groove and the second slide groove by a screw rod, and the screw rod is tightened by screwing a nut; H-shaped brackets 54 are installed on both sides of the support plate 51.

[0028] Furthermore, the main prompt screen mechanism 6 includes a rotating shaft 65 installed at the front end of the top face of the movable plate 52, a vertical plate is fixedly installed on the rotating shaft 65, a first wire hole and a first mounting screw hole are installed on the vertical plate, and a main prompt screen 61 is installed in front of the vertical plate and fastened by a screw and a nut; a second servo motor 66 is installed at the front end of one side of the movable plate 52, and the shaft of the second servo motor 66 is connected to the rotating shaft 65 to control the flipping of the vertical plate; a position sensor 63 and a rubber shock-absorbing block 62 are installed at the front end of the top face of the movable plate 52; a second vertical limiting convex plate 64 is arranged on the edge of the front end of the top face of the movable plate 52.

[0031] Furthermore, rollers 9 with brake handles are respectively installed on both sides of the bottom surface of the base 1.

[0032] The working principle of the utility model is as follows:

[0033] In this design, rollers 9 with brake handles are respectively installed on both sides of the bottom surface of the base 1 to facilitate movement.

[0034] In this design, a remote control switch 83 is used to control the PLC controller. The PLC controller controls the first motor 44 to work. The first motor 44 drives the first pulley 43 to rotate. The first pulley 43 controls the second synchronous wheel 41 to rotate through the synchronous belt 42 (since the second synchronous wheel 41 is installed on the turntable 46, the second synchronous wheel 41 can be driven to rotate through the synchronous belt). The second synchronous wheel 41 drives the nut to rotate, and the nut drives the screw rod 31 to rise and fall. Since a square guide cylinder 32 is installed at the bottom end of the screw rod 31, and the square guide cylinder 32 is installed on the square support cylinder 2, the rotation of the screw rod is limited to ensure that the screw rod moves straight up and down. This drives the horizontal telescopic platform 5 to rise and fall.

[0035] In this design, the horizontal telescopic platform 5 includes a support plate 51 installed at the top of the screw rod 31, two parallel first slide grooves are arranged on both sides of the top surface of the support plate 51, and a movable plate 52 is installed on the support plate 51. Second slide grooves are arranged on both sides of the top surface of the movable plate 52 corresponding to the first slide grooves. The movable plate 52 passes through the first and second slide grooves through screw rods, and is tightened by screwing the screw rods with nuts; H-shaped brackets 54 are installed on both sides of the support plate 51. Therefore, by loosening the screw rods and nuts, the support plate 51 can be set to move horizontally, so as to more conveniently control the position of the main prompt screen mechanism 6 and facilitate the use of the prompting of the broadcast host.

[0036] In this design, when the main prompt screen 61 in the main prompt screen mechanism 6 suddenly fails, the control switch on the remote control switch 83 is turned on (the color of the switch can be painted red to facilitate the first-time identification). Then the second servo motor 66 is controlled to work, driving the rotating shaft 65 to rotate synchronously, driving the vertical plate connected to the rotating shaft to rotate synchronously, driving the main prompt screen 61 connected to the vertical plate to flip backward to the rubber shock-absorbing block 62, and at the same time hitting the position sensor 63, the position sensor 63 sends a signal to the PLC controller, and the PLC controller controls the second servo motor 66 to stop working. At this time, the main prompt screen 61 on the movable plate 52 is laid flat, and the auxiliary prompt screen 71 behind it is displayed, ensuring the seamless connection of the prompts in the broadcasting and hosting work, and will not cause the prompt work to fail.

[0037] In this design, a first motor shield 45 is installed on one side of the square support tube 2, and a second shaft hole is opened on the top surface of the first motor shield 45 to facilitate the extension of the shaft of the first motor 44 and play a protective role.
