[0019] Compared with the prior art, the present invention provides a news display with multiple protection functions, having the following beneficial effects:

[0020] 1. The present invention adjusts the deviation angle of the display through the rotation of the deviation rod and the deviation connecting block. The distance between the deviation rod and the deviation connecting block is adjusted through the telescopic assembly, so as to adjust the distance between the display and the support rod, enabling the display to flexibly adjust the deviation position to adapt to different usage environments. And during the adjustment process, the display is angle-locked through the angle-locking assembly to ensure that the display screen does not rotate during the deviation process, avoiding the display from being skewed after adjusting the deviation position.

[0021] 2. The angle-locking assembly of the present invention realizes the precise adjustment and locking of the display screen angle through the coordinated work of the fixed rotating shaft and the angle-locking rotating shaft, combined with the meshing structure of the angle-locking toothed belt and the tooth groove. When the display screen deviates, the fixed rotating shaft synchronously adjusts the angle of the angle-locking rotating shaft through the angle-locking toothed belt, so that the angle-locking rotating shaft does not rotate, making the display screen not rotate during the deviation process and not being skewed.

[0022] 3. The present invention ensures that the angle-locking toothed belt always maintains an appropriate tension between the fixed rotating shaft and the angle-locking rotating shaft through the coordinated work of the outer fixed tension shaft, the outer tension adjustment shaft and the tension telescopic rod. When the deviation distance between the display screen and the support structure changes, the tension mechanism can automatically adjust the folding length of the angle-locking toothed belt to make its tension match the overall length of the deviation rod and the deviation connecting block. The settings of the tension telescopic rod and the limit frame further enhance the stability of the mechanism, ensuring that the angle-locking toothed belt does not become loose or overstretched during the movement process, avoiding functional failure.

[0023] 4. The hydraulic linkage system of the display of the present invention transmits the deviation action of the display screen to the auxiliary support assembly through the flow of hydraulic oil, automatically adjusting the expansion and retraction of the support plate. When the display screen deviates, the hydraulic system pushes the support plate to expand towards the deviating side, providing additional support force to prevent the display from tipping over due to unstable center of gravity.

[0024] 5. The display of the present invention is equipped with a protective airbag and a protective film on the outside, providing double protection for the display screen. The protective airbag can absorb external impacts and reduce the risk of damage to the display screen, while the protective film prevents the screen surface from being scratched or contaminated, improving the durability and service life of the display.

Specific embodiments

[0042] 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 creative efforts shall fall within the protection scope of the present invention.

[0043] The present invention provides as Figures 1 - 16A news display with multiple protection functions is shown, including a support base 1. A vertically upward support rod 2 is fixedly connected to the rear side of the upper end of the support base 1. The upper end of the support rod 2 is connected to a hydraulic tank 3. A deviation rotating rod 4 with an opening to the left is arranged at the front end of the hydraulic tank 3. The left end of the deviation rotating rod 4 is connected to a deviation connecting block 5 with an opening to the right through a telescopic component. A display screen 6 is arranged at the front end of the deviation connecting block 5. A corner locking component is arranged between the hydraulic tank 3 and the display screen 6, and the corner locking component is arranged inside the deviation rotating rod 4 and the deviation connecting block 5 and is located between the deviation rotating rod 4 and the deviation connecting block 5. A hydraulic linkage component is arranged between the auxiliary support component and the corner locking component. A protective airbag 7 is clamped outside the display screen 6, and a protective film is arranged at the front end of the display screen 6. The display screen 6 of the news display is protected multiple times through the externally clamped protective airbag 7 and the protective film. It is connected to the hydraulic tank 3 through the deviation rotating rod 4, the deviation connecting block 5 and the telescopic component, and can be supported at the bottom through the support base 1, the support rod 2 and the hydraulic tank 3. Moreover, the deviation rotating rod 4 and the deviation connecting block 5 can rotate to make the display screen 6 deviate by a certain angle to the left and right sides of the support rod 2 and the hydraulic tank 3, and the deviation distance between the display screen 6 and the support rod 2 and the hydraulic tank 3 can be adjusted by the telescopic of the telescopic component, so that the news display can adjust the position of the display screen 6 according to the use environment, thereby improving the environmental adaptability of the news display during use.

[0044] Optionally, the protective airbag 7 is made of an internally inflated rubber airbag. The inner wall of the protective airbag 7 is fixed at the surrounding positions of the display screen 6 by pasting. The protective film is a tempered film of the existing technology and is directly pasted on the display screen 6 by using the existing pasting technology.

[0045] Such as Figure 3 、 Figure 5 、 Figure 7 and Figure 10As shown, the corner locking assembly includes a fixed rotating shaft 8, a fixed external tooth groove 9, a connecting disk 12, a corner locking rotating shaft 13, a corner locking tooth groove 14, and a corner locking tooth belt 19. The fixed rotating shaft 8 is fixedly connected to the front end of the hydraulic tank 3 and penetrates forward inside the right side of the offset rotating rod 4. The offset rotating rod 4 is rotationally connected to the hydraulic tank 3 through the fixed rotating shaft 8. The fixed external tooth groove 9 is opened in the middle of the cylindrical outer wall of the fixed rotating shaft 8 and is located inside the offset rotating rod 4. The connecting disk 12 is fixedly connected to the center of the rear end of the display screen 6. There are studs on the connecting disk 12 for the installation of the display screen 6. The display screen 6 and the connecting disk 12 are fixedly connected through studs and nuts. The corner locking rotating shaft 13 is fixedly connected to the center of the rear end of the connecting disk 12 and penetrates through the offset connecting block 5 from front to back. The corner locking rotating shaft 13 is rotationally connected to the offset connecting block 5. A second locking mechanism is provided between the offset connecting block 5 and the corner locking rotating shaft 13 and is limited by a second locking component. The corner locking tooth groove 14 is opened in the middle of the cylindrical outer wall of the corner locking rotating shaft 13 and is located inside the offset connecting block 5. The outer diameter of the corner locking tooth groove 14 is equal to the outer diameter of the fixed external tooth groove 9. The corner locking tooth belt 19 is sleeved outside the fixed rotating shaft 8 and the corner locking rotating shaft 13 and is clamped inside the fixed external tooth groove 9 and the corner locking tooth groove 14. Rolling teeth are provided on the inner wall of the cylindrical surface of the fixed external tooth groove 9, the inner wall of the cylindrical surface of the corner locking tooth groove 14, and the inner wall of the corner locking tooth belt 19, and they are meshed with each other through the rolling teeth. A tension mechanism is provided on the outer side between the fixed rotating shaft 8 and the corner locking rotating shaft 13 for adjusting the tension of the corner locking tooth belt 19 between the fixed rotating shaft 8 and the corner locking rotating shaft 13. During the process of rotating the offset rotating rod 4 and the offset connecting block 5, when the display screen 6 is forcefully pulled, the offset rotating rod 4 and the offset connecting block 5 are driven to rotate around the fixed rotating shaft 8 by the display screen 6. Since the corner locking tooth belt 19 is connected between the fixed rotating shaft 8 and the corner locking rotating shaft 13 and is meshed with the fixed external tooth groove 9 and the corner locking tooth groove 14 through the rolling teeth, and the position of the fixed rotating shaft 8 is fixed, there will be no sliding or rolling between the fixed rotating shaft 8 and the corner locking tooth belt 19. When the offset rotating rod 4 and the offset connecting block 5 maintain the overall length unchanged and rotate from the middle position to one side, the corner locking tooth belt 19 on the side of the rotation direction will unwind and become longer from inside the fixed external tooth groove 9, and the corner locking tooth belt 19 on the side away from the rotation direction will wind into the fixed external tooth groove 9 and become shorter. Since the distance between the fixed rotating shaft 8 and the corner locking rotating shaft 13 is limited by the overall length of the offset rotating rod 4 and the offset connecting block 5, the distance between the fixed rotating shaft 8 and the corner locking rotating shaft 13 remains unchanged. At this time, the longer side of the corner locking tooth belt 19 will exert a pushing force on the corner locking rotating shaft 13, and the shorter side of the corner locking tooth belt 19 will exert a pulling force on the corner locking rotating shaft 13, thereby driving the corner locking rotating shaft 13 to rotate inside the offset connecting block 5. When the offset rotating rod 4 and the offset connecting block 5 rotate, the corner locking rotating shaft 13 rotates in the opposite direction of the rotation of the offset rotating rod 4 and the offset connecting block 5 inside the offset connecting block 5, and adjusts the lengths of both sides of the corner locking tooth belt 19 through the rotation to make the lengths of both sides of the corner locking tooth belt 19 equal.To ensure that the deviation rod 4 and the deviation connection block 5 continue to rotate.,

[0046] As Figure 1 and Figure 2 shown, since the outer diameter of the locking angle tooth groove 14 is equal to the outer diameter of the fixed outer tooth groove 9, the fixed rotating shaft 8 and the locking angle rotating shaft 13 connected by the locking angle tooth belt 19 rotate the same angle relative to the deviation rod 4 and the deviation connection block 5, so that the angle of rotation of the locking angle rotating shaft 13 relative to the deviation rod 4 and the deviation connection block 5 is the same as the angle of rotation of the deviation rod 4 and the deviation connection block 5 relative to the fixed rotating shaft 8, but in the opposite direction. Therefore, the locking angle rotating shaft 13 does not rotate axially, but only deviates by a certain angle around the fixed rotating shaft 8, so that the display screen 6 connected to the locking angle rotating shaft 13 through the connection disk 12 also does not rotate axially, but only deviates by a certain angle around the fixed rotating shaft 8, thereby locking the angle of the display screen 6 and preventing the display screen 6 from tilting during the deviation process.

[0047] As Figure 3 、 Figure 7 、 Figure 9 and 11As shown in the figure, the second locking mechanism includes a locking connection plate 24, a second locking pressure plate 25, and a second locking spring 26. A second locking box 23 is provided at the rear end of the deviation connection block 5. The rear end of the locking angle rotating shaft 13 is fixedly connected to the locking connection plate 24, and the locking connection plate 24 is rotatably connected inside the second locking box 23. The rear end of the locking connection plate 24 is provided with a second locking pressure plate 25. The second locking pressure plate 25 is located inside the second locking box 23. Its limit card slot is arranged on the cylindrical outer wall of the second locking pressure plate 25, and the limit card strip is arranged on the cylindrical inner wall of the second locking box 23. It is limited to the second locking box 23 through the limit card slot and the limit card strip, and the second locking pressure plate 25 is slidably connected inside the second locking box 23. The rear end of the second locking pressure plate 25 is provided with a second locking spring 26 and is elastically connected inside the second locking box 23 through the second locking spring 26. A plurality of locking card slots 27 arranged in a trapezoidal shape are provided on the outer side of the rear end of the locking connection plate 24. A plurality of locking card heads 28 arranged in a trapezoidal shape are fixedly connected to the outer side of the front end of the second locking pressure plate 25, and the plurality of locking card heads 28 are respectively clamped inside the plurality of locking card slots 27. During the process of pulling the display screen 6, since the second locking pressure plate 25 is limited to the second locking box 23 through the limit card slot and the limit card strip, and the second locking box 23 is fixedly connected to the rear end of the deviation connection block 5, the second locking pressure plate 25 will rotate around the fixed rotating shaft 8 together with the deviation connection block 5. The locking angle rotating shaft 13 rotates in the opposite direction to the deviation connection block 5. At this time, the plurality of locking card heads 28 arranged in a trapezoidal shape at the front end of the second locking pressure plate 25 slide out of the plurality of locking card slots 27 arranged in a trapezoidal shape under the extrusion of the trapezoidal inclined surface, overcoming the elastic force of the second locking spring 26, thereby releasing the locking between the deviation connection block 5 and the locking angle rotating shaft 13, ensuring that the locking angle rotating shaft 13 can rotate, and ensuring that the display screen 6 can deviate by a certain angle.

[0048] As Figure 9 shown, when stopping pulling the display screen 6, both the deviation connection block 5 and the locking angle rotating shaft 13 stop rotating. At this time, the plurality of locking card heads 28 will be clamped into the plurality of locking card slots 27 again under the action of the second locking spring 26, locking the positions of the deviation connection block 5 and the locking angle rotating shaft 13 again, thereby locking the position between the deviation connection block 5 and the display screen 6, and restricting the positions of the deviation rotating rod 4 and the deviation connection block 5 through the meshing between the fixed external tooth groove 9 and the locking angle tooth groove 14 and the locking angle tooth belt 19, so that the deviation rotating rod 4 and the deviation connection block 5 will not rotate again under the gravity of the display screen 6, ensuring that the deviation angle of the display screen 6 remains unchanged and ensuring the stable position of the display screen 6.

[0049] As Figure 3 , Figure 4 , Figure 6 and Figure 8, the telescopic assembly includes a telescopic chute 11 and a telescopic rack 15. The telescopic chute 11 is opened on the upper and lower outer walls of the left end of the offset rod 4, and is respectively located on the upper and lower sides of the opening of the offset rod 4. Two telescopic racks 15 are fixedly connected to the upper and lower outer walls of the right end of the offset connecting block 5, and are located on the upper and lower sides of the opening of the offset connecting block 5. The two telescopic racks 15 are respectively inserted into the two telescopic chutes 11 and are slidably connected to the two telescopic chutes 11. And a limit stop block is provided at the right end of each of the two telescopic racks (as Figure 6 shown). A first locking mechanism is provided between the two telescopic chutes 11 and the two telescopic racks 15, and is limited by a first locking component. The first locking mechanism includes a first locking box 20, a first locking spring 21 and a first locking pressing plate 22. First locking boxes 20 are provided on the left sides of the upper and lower ends of the offset rod 4, and the two first locking boxes 20 are respectively communicated with the interiors of the two telescopic chutes 11 and are located outside the two telescopic racks 15. First locking springs 21 are provided inside the two first locking boxes 20. First locking pressing plates 22 are provided at the ends of the two first locking springs 21 close to the telescopic chutes 11, and the two first locking pressing plates 22 are respectively in contact with the two telescopic racks 15. Limit teeth are provided at the ends of the two telescopic racks 15 in contact with the two first locking pressing plates 22, and are engaged with each other through the limit teeth. During the process of adjusting the offset distance between the display screen 6, the support rod 2 and the hydraulic tank 3, pull and push the display screen 6 forcefully along the sliding direction of the offset rod 4 and the offset connecting block 5. The display screen 6 drives the offset connecting block 5 to approach or move away from the offset rod 4. At this time, the offset connecting block 5 drives the telescopic rack 15 to be squeezed to one side, and part of the squeezing force is converted into a pushing force on the first locking pressing plate 22 through the inclined surface of the limit teeth. When the pushing force overcomes the elastic force of the first locking spring 21, the limit teeth of the first locking pressing plate 22 will slide out from the limit teeth inside the telescopic rack 15, so that the telescopic rack 15 can slide inside the telescopic chute 11, so that the offset connecting block 5 can approach or move away from the offset rod 4. When the offset connecting block 5 approaches or moves away from the offset rod 4, the offset connecting block 5 can adjust the distance from the offset rod 4 through the sliding of the telescopic rack 15 inside the telescopic chute 11, and guide the approach and separation of the offset connecting block 5, so that the offset rod 4 and the offset connecting block 5 can approach and separate through the telescopic assembly, thereby adjusting the offset distance between the display screen 6, the support rod 2 and the hydraulic tank 3.

[0050] In addition, a limit stop is provided at the right end of the telescopic rack 15, which can effectively prevent the telescopic rack 15 from completely sliding out of the inside of the telescopic chute 11 and causing detachment. After adjusting the deviation distance between the display screen 6, the support rod 2, and the hydraulic tank 3, stop pulling and pushing the display screen 6. At this time, the first locking pressure plate 22 meshes with the telescopic rack 15 again under the action of the first locking spring 21 and restricts the position of the telescopic rack 15, thereby restricting the distance between the deviation rotating rod 4 and the deviation connecting block 5 and ensuring the stable position of the display screen 6.

[0051] As Figure 10 shown, the tension mechanism includes an outer fixed tension shaft 10, a tension telescopic rod 16, a limit frame 17, and an outer tension adjustment shaft 18. Outer fixed tension shafts 10 are provided at the four corners inside the deviation rotating rod 4, and the four outer fixed tension shafts 10 are arranged in a rectangle and are rotatably connected between the inner walls of the front and rear ends of the deviation rotating rod 4. A tension telescopic rod 16 is connected to the right end of the deviation connecting block 5, and the tension telescopic rod 16 is inserted into the inside of the deviation rotating rod 4. Limit frames 17 are fixedly connected to the front and rear sides of the right end of the tension telescopic rod 16. Outer tension adjustment shafts 18 are rotatably connected to the upper and lower sides between the two limit frames 17, and the two outer tension adjustment shafts 18 are located inside the two upper outer fixed tension shafts 10 and the two lower outer fixed tension shafts 10. The locking angle tooth belt 19 passes through in a "zigzag" shape between the two left outer fixed tension shafts 10 and the two outer tension adjustment shafts 18. The four outer fixed tension shafts 10 are in rolling connection with the inner wall of the locking angle tooth belt 19, and the two outer tension adjustment shafts 18 are in rolling connection with the outer wall of the locking angle tooth belt 19. During the process of adjusting the deviation distance between the display screen 6, the support rod 2, and the hydraulic tank 3, the tension of the locking angle tooth belt 19 between the fixed rotating shaft 8 and the locking angle rotating shaft 13 will be affected by the overall length of the deviation rotating rod 4 and the deviation connecting block 5. At this time, when the deviation connecting block 5 approaches the deviation rotating rod 4, the deviation connecting block 5 will drive the tension telescopic rod 16 and the limit frame 17 to approach the deviation rotating rod 4 together, and drive the two outer tension adjustment shafts 18 through the limit frame 17 to squeeze the locking angle tooth belt 19 between the two upper outer fixed tension shafts 10 and the two lower outer fixed tension shafts 10, thereby folding the locking angle tooth belt 19. At the same time, the distance between the deviation connecting block 5 and the outer tension adjustment shaft 18 is adjusted by the expansion and contraction of the tension telescopic rod 16 to adapt to the overall length of the locking angle tooth belt 19.

[0052] Among them, the outer tension adjustment shaft 18 is equivalent to a movable pulley during the folding process of the locking angle tooth belt 19, and the outer fixed tension shaft 10 is equivalent to a fixed point. According to the working principle of the pulley, the change value of the length between the deviation connecting block 5 and the deviation rotating rod 4 is the sum of the change value of the distance between the deviation connecting block 5 and the outer tension adjustment shaft 18 and the change value of the distance between the outer tension adjustment shaft 18 and the outer fixed tension shaft 10 on the left. Therefore, the locking angle tooth belt 19 can always maintain tension between the fixed rotating shaft 8 and the locking angle rotating shaft 13, enabling the locking angle assembly to operate stably at any overall length of the deviation rotating rod 4 and the deviation connecting block 5, and avoiding failure.

[0053] As Figure 10 shown, the tension telescopic rod 16 is composed of telescopic rod shafts at both ends, a telescopic rod sleeve in the middle, and two tension springs inside. The telescopic rod shafts at both ends are respectively connected to the deviation connecting block 5 and the two limit frames 17, and the two telescopic rod shafts slide inside the telescopic rod sleeve and are supported by the two tension springs. During the process of adjusting the deviation distance between the display screen 6, the support rod 2, and the hydraulic tank 3, the distance between the deviation connecting block 5 and the outer tension adjustment shaft 18 and the distance between the outer tension adjustment shaft 18 and the outer fixed tension shaft 10 on the left can both be adjusted by the sliding of the telescopic rod shaft inside the telescopic rod sleeve, and the support between the outer tension adjustment shaft 18 and the locking angle tooth belt 19 can be achieved through the tension spring, enabling the locking angle tooth belt 19 to always maintain tension between the fixed rotating shaft 8 and the locking angle rotating shaft 13, thereby ensuring that the operation of the telescopic assembly does not affect the operation of the locking angle assembly.

[0054] As another implementation manner, as Figure 3 、 Figure 5 、 Figure 12 、 Figure 13 and Figure 14 shown, the hydraulic linkage assembly includes a linkage mechanism and a hydraulic mechanism;

[0055] The linkage mechanism includes a fixed frame 29, a linkage rotating shaft 30, a driving gear 32, a steering gear 33, a steering gear sleeve 34, and a linkage gear 37. The linkage rotating shaft 30 is rotatably connected to the central axis of the fixed rotating shaft 8, and the rear end of the linkage rotating shaft 30 passes through the front end interior of the hydraulic tank 3 through a connecting rotating hole, and the connecting rotating hole is opened inside the front end of the hydraulic tank 3. The rear end of the connecting rotating hole communicates with a gear steering groove 31, and the rear end of the gear steering groove 31 communicates with a gear groove 36. The front end of the linkage rotating shaft 30 is fixedly connected to the fixed frame 29 and is fixedly connected to the front end of the deviation rotating rod 4 through the fixed frame 29 (as Figure 16As shown, a drive gear 32 is connected to the rear end of the linkage rotating shaft 30. The drive gear 32 passes through the central axis of the gear steering groove 31 and is rotatably connected inside the gear steering groove 31. A plurality of steering gears 33 are rollingly connected to the outside of the drive gear 32, and the drive gear 32 meshes with the plurality of steering gears 33. The plurality of steering gears 33 are all rotatably connected to the front end inner wall of the gear steering groove 31 through the central rotating shafts. A steering gear sleeve 34 is sleeved on the outside of the plurality of steering gears 33, and the plurality of steering gears 33 are rollingly connected to the inner wall of the steering gear sleeve 34 and mesh with the inner wall of the steering gear sleeve 34. The steering gear sleeve 34 is rotatably connected inside the gear steering groove 31. A linkage gear 37 is fixedly connected to the rear end of the steering gear sleeve 34, and the linkage gear 37 is rotatably connected inside the gear groove 36. When the display screen 6 deviates from the support rod 2 and the hydraulic tank 3 by a certain angle, the deviation rotating rod 4 drives the linkage rotating shaft 30 to rotate in the same direction through the fixing bracket 29, and drives the drive gear 32 to rotate inside the gear steering groove 31 through the linkage rotating shaft 30. At this time, the drive gear 32 drives the plurality of external steering gears 33 to rotate in the opposite direction, and the plurality of steering gears 33 drive the steering gear sleeve 34 and the linkage gear 37 to rotate in the opposite direction to the drive gear 32, so that the deviation rotating rod 4 drives the linkage gear 37 to rotate in the opposite direction.

[0056] As Figure 3 , Figure 12 and Figure 13As shown in the figure, the hydraulic mechanism includes a hydraulic cylinder 39, a linkage rack 40, a hydraulic piston 41, a connecting oil pipe 42, and a hydraulic chute 43. Both the left and right ends of the gear groove 36 communicate with the vertically arranged rack chutes 38. Two hydraulic cylinders 39 are respectively connected to the lower ends of the two rack chutes 38. Two linkage racks 40 are respectively slidably connected inside the two rack chutes 38 and can be telescoped by sliding inside the two hydraulic cylinders 39. Two hydraulic pistons 41 are respectively rotatably connected to the lower ends of the two linkage racks 40 and are respectively slidably connected inside the two hydraulic cylinders 39. Rubber sealing rings are provided between the two hydraulic pistons 41 and the two hydraulic cylinders 39. Two connecting oil pipes 42 are respectively connected to the lower ends of the two hydraulic cylinders 39 and penetrate through the support base 1 and the support rod 2 in an "L" shape. Hydraulic chutes 43 are respectively opened inside the front and rear sides of the left and right ends of the support base 1, and the two hydraulic chutes 43 on the same side communicate with the connecting oil pipe 42 on the same side. Hydraulic oil is provided inside the two hydraulic cylinders 39, the two connecting oil pipes 42, and the two hydraulic chutes 43, and the hydraulic oil is located below the two hydraulic pistons 41. When the display screen 6 deviates to one side, the linkage gear 37 rotates in the direction opposite to the rotation of the deviating rod 4. At this time, the linkage gear 37 drives the linkage rack 40 on the side close to the deviating direction of the display screen 6 to move downward, and drives the hydraulic piston 41 to slide downward inside the hydraulic cylinder 39 on the side close to the deviating rod 4 and the deviating connection block 5, so that the hydraulic oil inside the hydraulic cylinder 39 on the side close to the deviating rod 4 and the deviating connection block 5 enters the connecting oil pipe 42. At the same time, the linkage gear 37 drives the linkage rack 40 on the side far from the deviating direction of the display screen 6 to move upward, and drives the hydraulic piston 41 to slide upward inside the hydraulic cylinder 39 on the side far from the deviating rod 4 and the deviating connection block 5, so that the hydraulic oil inside the connecting oil pipe 42 on the side close to the deviating rod 4 and the deviating connection block 5 is sucked into the hydraulic cylinder 39.

[0057] At this time, as Figure 14 and Figure 15, auxiliary support components are arranged inside both left and right ends of the support base 1. The auxiliary support components include hydraulic push blocks 44, telescopic connecting rods 45 and support plates 46. Support plates 46 are arranged at both left and right ends of the support base 1. Both front and rear sides of one end of the two support plates 46 close to the support base 1 are fixedly connected with telescopic connecting rods 45, and the four telescopic connecting rods 45 are respectively inserted into four hydraulic sliding grooves 43. One end of the four telescopic connecting rods 45 away from the support plates 46 is fixedly connected with hydraulic push blocks 44, and the four hydraulic push blocks 44 are respectively slidably connected inside the four hydraulic sliding grooves 43, and rubber sealing rings are arranged between the four hydraulic push blocks 44 and the four hydraulic sliding grooves 43. Therefore, the connecting oil pipe 42 close to the deviation direction side of the display screen 6 introduces hydraulic oil into the hydraulic sliding groove 43, and pushes the hydraulic push blocks 44 and the telescopic connecting rods 45 to slide towards the deviation direction side close to the display screen 6, so as to expand the support plate 46 on the deviation direction side close to the display screen 6 to the side away from the support base 1, while the connecting oil pipe 42 on the other side sucks the hydraulic oil in the hydraulic sliding groove 43 on the other side into the hydraulic cylinder 39 on the other side, so that the support plate 46 on the other side retracts towards the side close to the support base 1, enabling the support plate 46 to assist in supporting the deviated display screen 6 through expansion, avoiding the center of gravity of the news display being unstable due to the deviation of the display screen 6, and preventing the news display from tipping over.

[0058] Among them, a plurality of drag reduction balls 47 are rotatably connected inside the lower ends of the two support plates 46. During the expansion process of the support plates 46, the resistance of expansion and retraction can be reduced by the plurality of drag reduction balls 47 rolling inside the lower ends.

[0059] Preferably, the display screen 6 can only be adjusted for deviation within 180° below the horizontal positions of the deviation rotating rod 4 and the deviation connecting block 5.

[0060] At this time, when the hydraulic piston 41 on one side slides to the lowermost side of the hydraulic cylinder 39, the support plate 46 on the same side expands to the maximum position. At the same time, the deviation rotating rod 4 and the deviation connecting block 5 rotate to the horizontal position. The hydraulic piston 41 on the other side slides to the uppermost side of the hydraulic cylinder 39, and the support plate 46 on the other side contracts to fit with the support base 1. When the display screen 6 rotates to the front of the support rod 2 and the hydraulic tank 3, the two hydraulic pistons 41 are respectively located at the middle positions of the two hydraulic cylinders 39. At the same time, the four hydraulic push blocks 44 respectively slide to the middle positions of the four hydraulic sliding grooves 43, and the two support plates 46 are in a symmetrical state.
