Description

Technical Field

[0001] This application belongs to the technical field of teleprompter device structure, specifically relating to a hand-cranked teleprompter. Background Technology

[0002] Currently, live streaming is an emerging form of highly interactive video entertainment. Today's live streaming platforms have entered the era of mobile video live streaming, where people can "watch, broadcast, and go anywhere." More and more people are willing to participate, live stream, and share their lives. Because live streaming has a low barrier to entry and can generate income, it has gradually become a way of working or entertaining for most people. However, in some live streams with specific goals, the person completing the live stream often needs to memorize a large number of lines or procedures, which has helped the development of teleprompters.

[0003] Among existing teleprompters, there is an audiovisual teleprompter (Chinese Patent, Application No. CN202223165057.6), which includes a hollow housing with a first surface facing the user; a teleprompter body connected inside the housing, having a display screen on the first surface for displaying text content; at least one speaker connected inside the housing, with its sound output direction facing the first surface; and a power connection module connected to the housing, electrically connected to both the teleprompter body and the speaker for supplying power to both. This audiovisual teleprompter features sound amplification, monitor functionality, and playback capabilities.

[0004] While the aforementioned teleprompters offer numerous functions, the use of teleprompters with displays can easily strain the eyes of broadcasters, given that live streaming already requires electronic devices such as mobile phones or computers. Furthermore, teleprompters with displays are more expensive. Cue cards are inconvenient to use during live streaming, and existing teleprompters that can use paper transcripts only have page-turning functions and are structurally complex with poor interactivity, as illustrated by the patent for a page-turning device and broadcast teleprompter (Chinese Patent, Application No. CN202510030750.1). Therefore, there is an urgent need for a solution that can address these problems. Utility Model Content

[0005] The purpose of this application is to provide a hand-cranked teleprompter to address the shortcomings of existing technologies. In practical applications, the teleprompter is rotated by hand-cranking the handle, which improves interactivity. At the same time, it has a simple structure and low cost.

[0006] To achieve the above objectives, this application adopts the following technical solution: A hand-cranked teleprompter includes: Placement board; The drive assembly includes a first fixing member and a hand crank mounted on the placement plate via the first fixing member. One end of the hand crank is equipped with a hand crank plate, and the hand crank plate is provided with a hand crank handle.

A second transmission member corresponding to the first transmission member is provided at one end of the rotating bearing near the drive assembly. The second transmission member rotates according to the rotation of the first transmission member. The transmission assembly includes a fixed plate and a transmission bearing mounted on the placement plate via the fixed plate. The transmission bearing is connected to the rotating bearing via a synchronous belt and is positioned above the rotating bearing. A second roller is sleeved on the transmission bearing. The fixed plate is equipped with a transparent baffle, and the first roller and the second roller are used to roll the teleprompter. The teleprompter is located between the transparent baffle and the first roller and the second roller.

[0007] As an improvement to the hand-cranked teleprompter described in this application, the rotating bearing and the transmission bearing are respectively fitted with corresponding first and second synchronous pulleys, and the synchronous belt is fitted on the first and second synchronous pulleys.

[0008] As an improvement of the hand-cranked teleprompter described in this application, two first fixing members are provided and located in the middle of the hand crank, and two second fixing members are provided and located at both ends of the rotating bearing. The first fixing members and the second fixing members have the same structure, each including an upper fixing body and a lower fixing body connected by a first screw. A first bearing is provided between the upper fixing body and the lower fixing body, and the hand crank and the rotating bearing respectively pass through their corresponding first bearings.

[0009] As an improvement of the hand-cranked teleprompter described in this application, the fixing plate is vertically connected to the placement plate, and two fixing plates are provided and arranged in parallel. The fixing plates are provided with mounting grooves, and the tops of the two fixing plates are respectively provided with third fixing members for fixing the transmission bearing. The third fixing members are fixed to the mounting grooves by matching second screws and second nuts.

[0010] As an improvement of the hand-cranked teleprompter described in this application, the third fixing member includes a mounting body and connecting bodies disposed on both sides of the mounting body. The connecting bodies are fixed to the mounting groove by the second screw and the second nut. The mounting body is configured as a hollow structure, and a second bearing is installed in the middle of the mounting body. The two ends of the transmission bearing are respectively disposed in their corresponding second bearings.

[0011] As an improvement of the hand-cranked teleprompter described in this application, the transparent baffle includes a first baffle, which is disposed corresponding to the transmission bearing. The two ends of the first baffle are respectively provided with first connecting members and connected to the two fixed plates. The first connecting members are fixed to the mounting groove by matching third screws and third nuts.

Simultaneously, the second and first rollers are synchronously driven by a synchronous belt, ensuring that the first and second rollers drive the rotation of the teleprompter, thus guaranteeing the normal operation of the teleprompter. This application uses paper teleprompters, avoiding the eye strain caused by multiple screens during live streaming. The hand crank mechanism increases interactivity and reduces fatigue from prolonged reading, thus decreasing the likelihood of users misreading the teleprompter. Furthermore, the transparent barrier ensures the stability of the connection between the teleprompter and the first and second rollers while also providing a certain level of guidance.

[0023] The following is in conjunction with the appendix Figures 1-3 The present application will be further described in detail with reference to specific implementation methods, but this is not intended to limit the present application.

[0024] Implementation A hand-cranked teleprompter includes a placement plate 1 and a drive assembly 2, a rotating assembly 3, a transmission assembly 4, and a transparent baffle 6 fixedly mounted on the placement plate 1. Compared with electronic displays, the hand-cranked teleprompter of this embodiment has a simple structure and low cost. During use, the teleprompter is surrounded by a first roller 33 in the rotating assembly 3 and a second roller 43 in the transmission assembly 4. The user provides power to the drive assembly 2 by hand-cranking. The use of the teleprompter avoids the situation where the live broadcaster needs to look at multiple electronic displays, which can cause eye strain. At the same time, the hand-cranked drive increases interactivity and allows the live broadcaster to focus on the teleprompter, avoiding the situation of forgetting the progress.

[0025] Specifically, the drive assembly 2 includes a first fixing member 21 and a hand crank 22 mounted on the placement plate 1 via the first fixing member 21. One end of the hand crank 22 is equipped with a hand crank disk 23, and the hand crank disk 23 is provided with a hand crank handle 24. The hand crank 22 can rotate according to the rotation of the hand crank handle 24. The other end of the hand crank 22 is provided with a first transmission member 25. In actual use, the user rotates the hand crank handle 24, and the hand crank disk 23 converts the rotation of the hand crank handle 24 into the rotation of the hand crank 22, thereby driving the rotation of the first transmission member 25.

[0026] Specifically, the rotating assembly 3 includes a second fixing member 31 and a rotating bearing 32 mounted on the placement plate 1 via the second fixing member 31. A first roller 33 is sleeved on the rotating bearing 32. A second transmission member 34 corresponding to the first transmission member 25 is provided at one end of the rotating bearing 32 near the drive assembly 2. The second transmission member 34 rotates according to the rotation of the first transmission member 25, so that when the first transmission member 25 rotates, the rotating bearing 32 drives the first roller 33 to rotate.

[0027] Specifically, there are two first fixing members 21 located in the middle of the hand crank 22, and two second fixing members 31 located at both ends of the rotating bearing 32. The first fixing members 21 and the second fixing members 31 have the same structure, both including an upper fixing body 72 and a lower fixing body 73 connected by a first screw 71. A first bearing 74 is provided between the upper fixing body 72 and the lower fixing body 73. The hand crank 22 and the rotating bearing 32 pass through their respective first bearings 74. While the first fixing members 21 and the second fixing members 31 are used for fixing, the first bearings 74 can also increase the flexibility of the rotation of the hand crank 22 and the rotating bearing 32.

[0028] Specifically, the transmission assembly 4 includes a fixed plate 41 and a transmission bearing 42 mounted on the placement plate 1 via the fixed plate 41. The transmission bearing 42 is connected to the rotating bearing 32 via a synchronous belt 5 and is positioned above the rotating bearing 32. A second roller 43 is fitted over the transmission bearing 42 so that the second roller 43 rotates synchronously when the transmission bearing 42 rotates.

[0029] Specifically, the rotating bearing 32 and the transmission bearing 42 are respectively fitted with corresponding first synchronous pulleys 35 and second synchronous pulleys 44. The synchronous belt 5 is fitted with the first synchronous pulley 35 and the second synchronous pulley 44. The synchronous belt 5 ensures the transmission connection between the rotating bearing 32 and the transmission bearing 42, and further ensures the normal use of the hand-cranked teleprompter. When the rotating bearing 32 rotates, it can drive the first synchronous pulley 35 to rotate, thereby causing the second synchronous pulley 44 to rotate synchronously with the first synchronous pulley 35, so that the transmission bearing 42 rotates synchronously with the rotating bearing 32, thereby causing the first roller 33 and the second roller 43 to roll the teleprompter synchronously, ensuring the normal use of the teleprompter.

[0030] Specifically, a fixing plate 41 is perpendicularly connected to a placement plate 1. Two fixing plates 41 are provided and arranged in parallel. The fixing plates 41 are provided with mounting grooves 412. The tops of the two fixing plates 41 are respectively provided with third fixing members 45 for fixing the transmission bearing 42. The third fixing members 45 are fixed to the mounting grooves 412 by matching second screws 46 and second nuts 47. A first washer 48 is provided between the second nut 47 and the mounting groove 412. The diameter of the first washer 48 is larger than the width of the mounting groove 412. In use, the distance between the first roller 33 and the second roller 43 can be changed by adjusting the position of the third fixing members 45, thereby increasing applicability.

[0031] Specifically, the third fixing component 45 includes a mounting body 451 and connecting bodies 452 disposed on both sides of the mounting body 451. The connecting bodies 452 are fixed to the mounting groove 412 by the second screw 46 and the second nut 47. The mounting body 451 is configured as a hollow structure. A second bearing 453 is installed in the middle of the mounting body 451. The two ends of the transmission bearing 42 are respectively disposed in their corresponding second bearings 453. The second bearings 453 increase the flexibility of the rotation of the transmission bearing 42.

[0032] Specifically, a transparent baffle 6 is installed on the fixed plate 41. The teleprompter is located between the transparent baffle 6 and the first roller 33 and the second roller 43. The transparent baffle 6 includes a first baffle 61 and a second baffle 62. The first baffle 61 is set corresponding to the transmission bearing 42. The two ends of the first baffle 61 are respectively provided with first connecting pieces 611 to connect to the two fixed plates 41. The first connecting pieces 611 are fixed to the mounting groove 412 by matching third screws 612 and third nuts 613. A second washer 614 is provided between the third nut 613 and the mounting groove 412. The diameter of the second washer 614 is larger than the width of the mounting groove 412. The second baffle 62 is set corresponding to the rotating bearing 32. The two ends of the second baffle 62 are respectively provided with second connecting pieces 621 to connect to the two fixed plates 41. A connecting groove 413 is also provided on the upper part, which is located below the mounting groove 412. The second connector 621 is fixed to the connecting groove 413 by a matching fourth screw 622 and a fourth nut 623. A third washer 624 is provided between the fourth nut 623 and the connecting groove 413. The diameter of the third washer 624 is larger than the width of the connecting groove 413. The positions of the first stop bar 61 and the second stop bar 62 can be adjusted according to the positional relationship between the first connector 611 and the second connector 621 and the fixing plate 41, which increases the applicability. At the same time, the first stop bar 61 and the second stop bar 62 have a certain indication function. In some other technical solutions of this embodiment, the first stop bar 61 and the second stop bar 62 can be set as red or other colored transparent bars to enhance the indication function.

[0033] Specifically, the end of the placement plate 1 away from the transmission component 4 is connected to a bracket 8, which is used to place external devices, such as mobile phones used during live streaming. The specific position can be adjusted according to actual needs to avoid the external devices blocking the teleprompter and increase practicality.

[0034] It is understandable that the combination of screws and nuts in this application makes the product easy to disassemble and facilitates later maintenance and repair. In addition, the installation of the rotatable components in this application does not affect their rotation due to the bearing configuration.

[0035] Furthermore, all content not described in detail in this specification is prior art known to those skilled in the art. Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this application is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on this application are within the scope of protection of this application. In addition, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this application.
