Detailed implementation manner

[0077] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0078] To achieve the above-mentioned invention purpose, as Figures 1 - 15 shown, the present invention provides a wall-mounted news teleprompter, including a news teleprompter display 2 and a support mechanism, the support mechanism is installed at the rear side of the news teleprompter display 2, so as to realize the support of the news teleprompter display 2, and its adjustment mechanism is installed between the support mechanism and the news teleprompter display 2, and is used to realize the connection and adjustment of the display and the support mechanism, and its mounting bracket 6 is installed at the rear side of the support mechanism, and is used to realize the wall-mounted installation of the support mechanism;

[0079] In this embodiment, the entire news teleprompter is installed and fixed on the corresponding wall through the mounting bracket 6, and the news teleprompter display 2 is supported through the mounting bracket 6 and the support mechanism. At this time, the news teleprompter words can be displayed on the news teleprompter display 2, so as to complete the news teleprompter work.

[0080] Optionally, the news teleprompter display 2 can be implemented using a display of the prior art for news teleprompter display work.

[0081] As Figure 2 shown, its adjustable counterweight mechanism 9 is slidably installed inside the support mechanism. The upper end of the adjustable counterweight mechanism 9 is connected to a belt 5, and the adjustable counterweight mechanism 9 is connected to the adjustment mechanism through the belt 5. In this way, through the setting of the adjustable counterweight mechanism 9, it can be used to balance the weight of the news teleprompter display 2, and further realize the stable adjustment of the lifting of the news teleprompter display 2;

[0082] As Figure 3 shown, its angle stabilizer 20 is located on both sides of the adjustment mechanism. In this way, through the setting of the angle stabilizer 20, the temporary locking after the angle adjustment of the news teleprompter display 2 can be realized, avoiding the angle deviation caused by the rotation of the news teleprompter display 2 due to its own gravity after the angle adjustment, and further realizing the stable adjustment of the angle of the news teleprompter display 2.

[0083] As Figure 1 、 2 shown, the support mechanism includes side support plates 8. Its bottom plate 1 is fixedly installed at the bottom end position of the side support plates 8, and its top plate 3 is fixedly installed at the top end position of the side support plates 8. Slide grooves 47 and counterweight grooves 48 are respectively formed on the opposite inner sides of the two side support plates 8. The counterweight groove 48 is located behind the slide groove 47. Tooth grooves 34 are provided at the middle positions between the slide groove 47 and the counterweight groove 48 on the opposite inner sides of the two side support plates 8. A chute 58 is penetratively formed in the right side support plate 8, and the chute 58 also passes through the right tooth groove 34 (a chute 58 is formed at the middle position of the right tooth groove 34, so that the pull rod 30 can slide up and down in the chute 58 at the middle position of the right tooth groove 34);

[0084] In this embodiment, the side support plates 8, the top plate 3, and the bottom plate 1 on the support mechanism together form a support frame, which can further support the news teleprompter display 2, and the side support plates 8 are fixedly connected to the top plate 3 and the bottom plate 1 respectively by bolts.

[0085] As Figure 2 、 3 shown, the adjustment mechanism includes an adjustment slide plate 10. Two fixed brackets 16 are fixedly installed at the front end position of the adjustment slide plate 10, and two rotating brackets 17 are fixedly installed at the rear end position of the news teleprompter display 2. The fixed bracket 16 and the rotating bracket 17 are rotatably connected by an angle adjustment shaft 23, and the angle adjustment shaft 23 and the rotating bracket 17 are fixedly connected by welding;

[0086] In this embodiment, the news prompting display 2 and the adjustment slide 10 are supported and rotationally adjusted by a fixed bracket 16, a rotating bracket 17, and an angle adjustment shaft 23, and the news prompting display 2 can rise and fall along with the adjustment slide 10.

[0087] Preferably, the rotating cylinder 18 is fixedly installed at the inner side of the two rotating brackets 17, and installation notches 21 are provided at both ends of the rotating cylinder 18. The two angle adjustment gears 19 are respectively sleeved and fixed on the rotating cylinder 18. The adjustment gears 19 provided on the rotating cylinder 18 can drive the rotation of the entire news prompt display 2 to achieve angle adjustment. The installation notches 21 provided on the rotating cylinder 18 can realize internal maintenance and installation. If it is necessary to weld the end of the angle adjustment shaft 23 to the rotating bracket 17, the operation can be performed through the installation notches 21.

[0088] like Figure 2 , 5 As shown, the adjustment mechanism also includes a function plate 14, wherein a containing chamber is provided inside the function plate 14, wherein an inner support plate 61 is fixedly arranged at an inner upper end position of the containing chamber, and a driving gear cylinder 29 and a transmission gear 22 are rotatably arranged on the inner support plate 61 and the relative inner wall of the containing chamber, and the angle adjustment gear 19 and the driving gear cylinder 29 are meshed and connected through the transmission gear 22;

[0089] In this embodiment, the driving gear cylinder 29 can engage and drive the transmission gear 22 to rotate. At this time, the rotating transmission gear 22 can drive the angle adjustment gear 19 to rotate. The rotating adjustment gear 19 can drive the rotating cylinder 18 to rotate, and then drive the news prompt display 2 connected to the rotating cylinder 18 to rotate, so that the angle of the news prompt display 2 can be adjusted. The power transmission is achieved through the setting of the transmission gear 22, which can make the angle conversion of the news prompt display 2 the same as the rotation angle of the handle 7.

[0090] like Figure 2 , 5 As shown, a pull rod 30 passes through the interior of the adjustment slide 10, and the right end of the pull rod 30 passes through the adjustment slide 10, and the right end of the pull rod 30 is connected to a handle 7, and the pull rod 30 also passes through the interior of the driving gear cylinder 29, and its driving shear frame 35 is rotatably installed in the interior of the accommodating chamber, and the pull rod 30 also passes through the interior of the driving gear cylinder 29, and the limiting rods 11 are slidably arranged on both sides of the bottom end of the driving shear frame 35, and the outer side of the limiting rod 11 is fixedly provided with a limiting plug 13, and a reset cylindrical groove 31 is opened inside the adjustment slide 10 and on both sides of the accommodating chamber, wherein the adjustment slide 10 also passes through the interior of the reset cylindrical groove 31, and a reset spring 32 is arranged inside the reset cylindrical groove 31 and sleeved on the pull rod 30, and a blocking disk 33 is arranged on the left end of the reset spring 32 and fixed on the pull rod 30;

[0091] In this embodiment, by pulling the pull handle 7 to the right to pull the pull rod 30, the blocking disc 33 on the pull rod 30 will compress the return spring 32, so that the return spring 32 is deformed and compressed, and then the pull rod 30 can be locked at the right side position inside the driving gear cylinder 29. At this time, by rotating the pull rod 30 through the pull handle 7, the driving gear cylinder 29 can be rotated, and then the rotation of the entire driving gear cylinder 29 can be realized, so that the angle can be adjusted. When the pull handle 7 is released, the pull rod 30 will reset under the action of the return spring 32, and then the pull rod 30 will be locked at the left side position inside the driving gear cylinder 29, thus preventing the driving gear cylinder 29 from rotating when the angle is not adjusted, so that the angle can be kept stable after adjustment.

[0092] As a further improvement, as Figure 9 shown, a sliding cylindrical groove 59 is formed at a position slightly to the left inside the driving gear cylinder 29, and a trapezoidal prism groove 37 is formed at a position slightly to the right inside the driving gear cylinder 29. Among them, the sliding cylindrical groove 59 and the trapezoidal prism groove 37 are in a communicating state. Trapezoidal prisms 38 and conical sliding cylinders 39 are respectively and fixedly arranged on the outer side of the pull rod 30, and the trapezoidal prism 38 is located at the right side of the conical sliding cylinder 39;

[0093] In this embodiment, when the pull rod 30 is pulled to the right, the pull rod 30 will drive the trapezoidal prism 38 to move to the right, so that the trapezoidal prism 38 can be inserted into the trapezoidal prism groove 38, and then the pull rod 30 is locked at the right side position inside the driving gear 29. At this time, the rotation of the pull rod 30 can drive the entire driving gear cylinder to rotate.

[0094] Preferably, the opening of the trapezoidal prism groove 37 on the side opposite to the trapezoidal prism 38 is large, and the cross-section of one end of the trapezoidal prism 38 opposite to the trapezoidal prism groove 37 is small, so that the trapezoidal prism 38 can be inserted into the trapezoidal prism groove 37 more smoothly.

[0095] Optionally, the trapezoidal prism 38 can be selected with a six-sided or more structure, and the trapezoidal prism groove 37 can be selected with a six-sided or more structure correspondingly, so that the trapezoidal prism 38 can be inserted into the trapezoidal prism groove 37 more conveniently.

[0096] As a further improvement, as Figure 9 shown, limiting and fixing rings 36 are respectively sleeved on the outer sides of the two driving gear cylinders 29. The left ends of the two limiting and fixing rings 36 are respectively fixed on the right side of the inner support plate 61 and the left inner wall of the accommodation chamber inside the position adjustment slide plate 10. A plurality of limiting grooves 40 are respectively formed on the inner walls of the limiting and fixing rings 36. A plurality of triangular blocks 43 are arranged at the left side position inside the driving gear cylinder 29. The triangular blocks 43 and the inner wall of the driving gear cylinder 29 are elastically connected through support springs 42, and limiting blocks 41 are fixedly arranged on the outer sides of the triangular blocks 43;

[0097] In this embodiment, when the pulled rod 30 is released, the rod 30 will move leftward under the action of the return spring 32. At this time, the leftward moving rod 30 will drive the conical slide cylinder 39 to move to the left. At this time, the leftward moving conical slide cylinder 39 will gradually squeeze the triangular block 43, and then the squeezed triangular block 43 will compress the support spring 42 and move outward, thereby driving the limit block 42 to move outward, so that the limit block 41 can be inserted into the limit groove 40 opened on the inner wall of the limit fixing ring 36, so that the driving gear cylinder 29 can be limited and locked relative to the limit fixing ring 36, avoiding the rotation of the driving gear 29 without angle adjustment.

[0098] Preferably, the limit groove 40 is a trapezoidal structure recessed inward with a large inner opening. There are sixteen limit grooves 40 provided according to requirements. The limit block 41 is a cuboid structure. The limit block 41 and the triangular block 43 are fixedly connected by welding, and a slope is cut at the position of the limit block 41 relative to the limit groove 40, so that the limit block 41 can be inserted into the limit groove 40 more smoothly for angle adjustment and locking. There are four limit blocks 41 in total, and the four limit blocks 41 are evenly distributed at the circumferential outer side position of the rod 30.

[0099] As a further improvement, as Figure 3 、 7 shown, the angle stabilizer 20 includes a stabilizer housing 24, which is fixedly installed at the outer side position of the fixed bracket 16. The annular sliding ring 25 is installed and fixed on the inner wall of the stabilizer housing 24 by welding, and a plurality of ball grooves are opened on the inner wall of the annular sliding ring 25. A plurality of shrinkage cylinders 28 are fixedly installed on the outer side of the angle adjustment rotating shaft 23 by welding, and a stabilizer spring 27 is arranged inside the shrinkage cylinder 28. The inner end of the stabilizer spring 27 is fixedly connected to the angle adjustment rotating shaft 23 by welding, and the sliding ball 26 is fixedly installed at the outer side position of the stabilizer spring 27 by welding. The sliding ball 26 can be clamped in the ball grooves opened on the inner wall of the annular sliding ring 25;

[0100] In this embodiment, when the angle adjustment of the angle news teleprompter 2 is realized, the angle adjustment rotating shaft 23 will rotate with the rotation of the news teleprompter 2. At this time, the rotating angle adjustment rotating shaft 23 will drive the shrinkage cylinder 28, the stabilizer spring 27, and the sliding ball 26 on its outer side to rotate, so that the sliding ball 26 can slide into and out of the ball grooves of the annular sliding ring 25, thereby realizing the damping rotation angle adjustment of the entire news teleprompter 2. When the angle adjustment of the news teleprompter 2 is completed, the sliding ball 26 will be clamped into the corresponding ball grooves of the annular sliding ring 25 under the extrusion of the stabilizer spring 27, so as to realize the temporary locking after the angle adjustment of the news teleprompter 2.

[0101] As a further improvement, as Figure 5 、 11 shown, the driving shear frame 35 includes a disk II 46, with pulling plates 44 fixedly arranged on the upper and lower sides of the disk II 46.

A disk I 45 is rotatably arranged at the rear end of the disk II 46. Pulling plates 44 are fixedly arranged on the upper and lower sides of the disk I 45. Long strip through holes are respectively opened on the pulling plates 44, and a sliding groove 60 is opened on the inner wall of the lower long strip through hole. The pull rod 30 passes through the long strip through holes inside the pulling plates 44 at the upper ends of the disk I 45 and the disk II 46, and a cylinder passes through the inside of the pull rod 30. The two ends of the cylinder pass through the pull rod 30 and slide inside the sliding groove 60 opened on the inner wall of the long strip through hole of the pulling plate 44 at the upper end of the disk II 46.
