Description

Technical Field

[0001] This utility model belongs to the technical field of interview equipment, specifically relating to a retractable interview teleprompter with a foldable display screen. Background Technology

[0002] Foldable teleprompters are portable prompting devices used in news interviews, program recordings, and social media filming. These devices typically consist of a lifting structure, a stable support structure, and a foldable teleprompter display component. The adjustable height of the teleprompter screen ensures the displayed content remains stably within the interviewee's field of vision, improving speaking fluency and filming efficiency. With increasing demands for lightweight design and multi-scene mobile filming, these teleprompters are evolving towards foldable, portable, and rapidly deployable designs, playing a crucial role in meeting the needs of different heights and shooting angles. However, existing telescopic teleprompters generally rely on the friction locking structure of the manual lifting bracket to maintain position during height adjustment. When the locking force is insufficient or the user does not hold the lifting bracket firmly during adjustment, the lifting bracket is prone to sudden slippage or even rapid drop. This rapid drop will not only cause the foldable teleprompter at the top to be impacted by gravity and inertia, posing a risk of equipment damage, but may also cause safety hazards such as falling and collision during on-site interviews. Utility Model Content

[0003] The purpose of this utility model is to provide a telescopic interview teleprompter with a foldable display screen, in order to solve the problem mentioned in the background art that the existing telescopic interview teleprompters often rely on a friction locking structure to maintain the position when adjusting the height. If the locking force is insufficient or the user does not firmly grasp the lifting bracket, the bracket may suddenly slide or fall quickly, which can easily cause the upper foldable teleprompter to be damaged by impact and create safety hazards such as falling and collision.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a telescopic interview teleprompter with a foldable display screen, comprising a lifting bracket and a lifting tube sleeve fitted over it. A reinforcing sleeve is fixedly fitted to the top of the lifting tube sleeve, and internally threaded cylinders are welded to the upper and lower sides of the front center of the lifting tube sleeve. Each of the two internally threaded cylinders is threaded with a hand-tightening height-fixing screw. After tightening, the screw can press tightly against the outer wall of the front end of the lifting bracket to prevent the lifting bracket from moving up and down. The bottom right end of the lifting bracket is connected to the right end of the lifting tube sleeve with an anti-fall stabilizing lifting device. The anti-fall stabilizing lifting device includes a lifting guide groove and a metal lifting guide block. The lifting guide groove is opened inside the right end of the lifting tube sleeve and is vertically arranged. The bottom right end of the lifting bracket is welded with a metal lifting guide block, the right end of which passes through the lifting guide groove.

[0005] Preferably, during the up-and-down movement of the lifting bracket in the lifting tube sleeve, it will simultaneously drive the metal lifting guide block to move up and down in the lifting guide groove, and the lifting guide groove can prevent the lifting bracket from rotating during the up-and-down movement through the metal lifting guide block.

[0006] Preferably, the anti-fall stabilizing lifting device further includes a rectangular sleeve, a hand-tightening screw, an adjusting screw hole, and a soft rubber friction block. The rectangular sleeve is fitted over the outside of the right end of the metal lifting guide block, and a hand-tightening screw is inserted into the center of its right end. An adjusting screw hole is opened inside the center of the metal lifting guide block, and the screw rod of the hand-tightening screw is threaded into the adjusting screw hole. Soft rubber friction blocks are attached and fixed to both the front and rear ends of the rectangular sleeve.

[0007] Preferably, during the tightening process of the hand-tightening screw, the rectangular sleeve will be pushed to the left, making it close to the outer wall of the right end of the lifting tube sleeve. The left ends of the two soft rubber friction blocks are protruding to the left. When the rectangular sleeve is close to the outer wall of the right end of the lifting tube sleeve, the two soft rubber friction blocks will first contact the front and rear outer walls of the right end of the lifting tube sleeve.

[0008] Preferably, the lifting bracket has a teleprompter mounting plate at the bottom front end, and the two are fixedly connected by multiple screw brackets. A foldable teleprompter is fixed to the front end of the teleprompter mounting plate by screws.

[0009] Preferably, the lifting bracket can change the height of the foldable teleprompter by moving up and down, and the top of the lifting bracket is set with a hemispherical shape, so that the center of the foldable teleprompter can be folded forward and backward on both the left and right sides.

[0010] Preferably, a welding sleeve is welded to the outside of the bottom end of the lifting tube sleeve, and a metal chassis is welded to the bottom end of the lifting tube sleeve.

[0011] Preferably, the circular outer wall of the metal chassis is welded with multiple wheel frames at equal intervals, and the bottom of each wheel frame away from the metal chassis is fixed with a brake wheel by screws.

[0012] Compared with the prior art, this utility model provides a retractable interview teleprompter with a foldable display screen, which has the following advantages: This utility model adds an anti-fall stabilizing lifting device to the bottom right end of the lifting bracket. This device can effectively prevent the lifting bracket from slipping rapidly during height adjustment, thereby improving the safety and controllability of the adjustment. At the same time, the device can also suppress the rotation of the lifting bracket inside the lifting tube sleeve, so that the teleprompter always maintains the correct orientation during the up and down adjustment, further improving the stability and accuracy of use. Specifically, by adjusting the contact tightness between the soft rubber friction block on the rectangular sleeve and the outer wall of the lifting tube sleeve, the magnitude of the friction resistance can be flexibly changed, so that the lifting bracket can move smoothly and slowly when pulled up or pushed down. Even if the user fails to hold the bracket firmly, it can avoid damage to the teleprompter or cause use risks due to sudden drop. In addition, the metal lifting guide block is inserted into the lifting guide groove at the right end of the lifting tube sleeve. It guides the lifting bracket synchronously as the lifting bracket moves up and down, which can significantly limit the rotation trend of the lifting bracket and ensure that the orientation of the foldable teleprompter remains stable. The hand-tightening screw and the threaded engagement of the adjusting screw hole can achieve fine adjustment of the moving distance of the rectangular sleeve, thereby precisely controlling the fit of the soft rubber friction block. The friction resistance can be adjusted as needed to adapt to foldable teleprompters of different weights or users' operating force habits. The overall adjustment process is more flexible, smoother and has higher reliability. Attached Figure Description

[0019] 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.

[0020] This utility model provides, for example Figure 1-5 The telescopic interview teleprompter with a foldable display screen shown is composed of a bottom support structure, a lifting and adjusting structure, a stabilizing and limiting structure, and an installation assembly for mounting the foldable teleprompter 13. The base of the device is a metal chassis 12, which provides overall weight and support strength. Multiple wheel frames 1 are spaced along the circumferential direction on its outer edge. Each wheel frame 1 has a braked moving wheel 2 fixedly mounted on the end away from the metal chassis 12 by screws. The multiple braked moving wheels 2 facilitate the rapid movement and positioning of the device in different interview scenarios, while the braking function can lock the device firmly before use, so that the metal chassis 12 forms a reliable support.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, a welding sleeve 3 is welded and fixed in the central area of ​​the metal chassis 12. The welding sleeve 3 extends upward and is fixedly connected to the lifting tube sleeve 4, so that the lifting tube sleeve 4 is kept vertical. The lifting tube sleeve 4 serves as the outer sleeve of the lifting support 7. A reinforcing sleeve 10 is provided on the outer side of its top to enhance the rigidity of the top cylinder wall and prevent deformation due to long-term adjustment. Two internally threaded cylinders 6 are provided on the front side of the reinforcing sleeve 10 and are connected to the inside of the lifting tube sleeve 4. The two are distributed vertically. Each internally threaded cylinder 6 is threaded with a hand-tightening height-fixing screw 5. When the user tightens the hand-tightening height-fixing screw 5, the screw of the hand-tightening height-fixing screw 5 will extend inward and press against the front outer wall of the lifting support 7 to fix the height of the lifting support 7.

[0022] like Figure 1 , Figure 2 and Figure 3As shown, the top of the lifting bracket 7 is connected to a teleprompter mounting plate 8. The teleprompter mounting plate 8 and the lifting bracket 7 are fixed together by multiple screws 9, which ensures that the mounting plate maintains good stability when under stress. The foldable teleprompter 13 is installed in front of the teleprompter mounting plate 8 and fixed with screws. The main body of the foldable teleprompter 13 can be folded to the left and right. When not in use, it can be folded up to reduce space occupation. When in use, after unfolding, it can be adjusted with the height of the lifting bracket 7 to accommodate the eye level of different cameras and interviewees. The top of the lifting bracket 7 adopts a hemispherical shape, which can avoid sharp corner interference during the folding and unfolding of the teleprompter and make it easy for users to hold.

[0023] like Figure 1 , Figure 4 and Figure 5 As shown, the lifting bracket 7 extends out from inside the lifting tube sleeve 4 and can move up and down within the lifting tube sleeve 4. A fall-prevention stabilizing lifting device 11 is provided on the bottom right side of the lifting bracket 7. This device is used to provide stable guidance and fall prevention during the lifting adjustment process. The key structure of the fall-prevention stabilizing lifting device 11 includes a lifting guide groove 14 provided on the inner wall of the right side of the lifting tube sleeve 4, and a metal lifting guide block 15 welded to the right end of the lifting bracket 7. The metal lifting guide block 15 cooperates with the lifting guide groove 14 to ensure that the lifting bracket 7 can maintain its direction without deviation when it moves vertically, thereby preventing the lifting bracket 7 from rotating inside the lifting tube sleeve 4 and causing the teleprompter angle to deviate from the interviewee's direction.

[0024] like Figure 1 , Figure 4 and Figure 5 As shown, a rectangular sleeve 16 is fitted over the metal lifting guide block 15, with a hand-tightening screw 17 on its right side. The screw of the hand-tightening screw 17 is threaded into the adjusting screw hole 18 inside the metal lifting guide block 15. Soft rubber friction blocks 19 are attached to the front and rear sides of the rectangular sleeve 16. When the user tightens the hand-tightening screw 17, the screw will push the rectangular sleeve 16 towards the outside of the lifting tube sleeve 4, causing the soft rubber friction blocks 19 to protrude towards the lifting tube sleeve 4 and rub against the outer wall of the right side of the lifting tube sleeve 4. The frictional resistance can impede or even temporarily lock the vertical movement of the lifting bracket 7, thereby providing timely resistance when the lifting bracket 7 shows a rapid downward trend due to gravity, preventing the lifting bracket 7 from suddenly falling, and ensuring the smoothness and safety of the height adjustment process.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
