DETAILED DESCRIPTION

[0028] First of all, it should be pointed out that in the different described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosure contained in the entire description can be transferred to the same parts with the same reference numerals or the same component names. Selected positional descriptions in the description, such as top, bottom, lateral, etc., also refer to the directly described and shown figures and are transferred to the new positions in the case of a change in position.

[0029] Example 1

[0030] A multi-angle rotatable bracket for a display screen includes a base 1, a support column 2, a rotating disk 3, a support mechanism 4 and an angle adjustment mechanism 5, see Figure 1-Figure 4 As shown, a support column 2 is installed in the middle of the top of the base 1 by welding, and a rotating disk 3 is rotatably mounted on the upper part of the support column 2 along the circumferential direction. A support mechanism 4 is arranged on the rotating disk 3. The support mechanism 4 is used to support and adjust the angle of the display screen. An angle adjustment mechanism 5 is arranged on the support mechanism 4. When the display screen is installed on the angle adjustment mechanism 5, the angle adjustment mechanism 5 can adjust the angle of the display screen.

[0031] The supporting mechanism 4 includes a hinge frame 41, a fixing rod 42 and a connecting tube 43, see Figure 1-Figure 3 As shown, the four ends of the rotating disk 3 are rotatably connected to the articulated frames 41, the outer ends of the four articulated frames 41 are fixedly penetrated by fixed rods 42, and the two sides of the four fixed rods 42 are rotatably fitted with connecting tubes 43, and the four connecting tubes 43 are connected to the angle adjustment mechanism 5.

[0032] The angle adjustment mechanism 5 includes a connecting column 51, a rotating seat 52 and a mounting plate 53. Figure 1 , Figure 2 and Figure 4As shown, the four connecting cylinders 43 are all slidably connected with connecting columns 51, and the connecting columns 51 are also rotatably connected to the connecting cylinders 43. The outer ends of the four connecting columns 51 are rotatably connected with rotating seats 52, and the outer ends of the four rotating seats 52 are rotatably connected with mounting plates 53. The operator can install the display screen on the mounting plate 53.

[0033] First, the operator installs four display screens on the angle adjustment mechanism 5, and then the display screen can be started. The display screen starts to display the information to be promoted, and people can pull the angle adjustment mechanism 5 to swing through the support mechanism 4. The angle adjustment mechanism 5 drives the display screen to swing. When the display screen swings to the required angle, the support mechanism 4 stops driving the angle adjustment mechanism 5 to swing, and the angle adjustment mechanism 5 also stops driving the display screen to swing. The angle adjustment mechanism 5 pulls the display screen to swing and further adjusts the angle. When the display screen adjusts the required angle, the information displayed on the display screen can be viewed. The angle adjustment mechanism 5 can also be used to pull the display screen outward, so that the display screen is closer to people, so that people can see the information displayed on the display screen more clearly. When another person needs to view, since the rotating disk 3 and the support column 2 are rotatably connected, the display screen can be directly pulled to rotate through the support mechanism 4 and the angle adjustment mechanism 5. When the display screen rotates to a suitable viewing position, the display screen stops pulling the display screen to rotate, and the other person can view the information on the display screen. In this way, the display screen is adjusted at multiple angles, which makes it more convenient for people to view the information on the display screen.

[0034] When the display screen starts to display the information to be promoted, the display angle adjustment mechanism 5 can be pulled up and down by the fixed rod 42. The up and down swing of the angle adjustment mechanism 5 drives the display screen to swing up and down. When the display screen swings up and down to a suitable angle, the angle adjustment mechanism 5 is stopped from swinging up and down, and the angle adjustment mechanism 5 can be pulled to swing horizontally through the action of the articulated frame 41, so that the display screen swings horizontally. When the display screen swings horizontally to a suitable viewing angle, the angle adjustment mechanism 5 is stopped from being pulled, and the information on the display screen can be started to be viewed.

[0035] When the angle of the display screen is initially adjusted by the hinge frame 41 and the fixing rod 42, the horizontal angle of the display screen is further adjusted by the rotating seat 52. After the horizontal angle of the display screen is further adjusted, the display screen is pulled up and down to further adjust the angle. When the display screen swings up and down to a suitable viewing angle, stop pulling the display screen and then pull the display screen outward. The outward movement of the display screen drives the rotating seat 52 to move outward. The outward movement of the rotating seat 52 drives the connecting column 51 to move outward. When the display screen moves outward to a suitable position, stop pulling the display screen outward and start viewing the information on the display screen. Since the display screen is closer to people, people can see the information displayed on the display screen more clearly.

[0036] Example 2

[0037] On the basis of embodiment 1, a stepless rotating mechanism 6 is also included. The stepless rotating mechanism 6 includes a connecting plate 61, a supporting spring 62, a rotating plate 63 and a ball 64. Figure 2 , Figure 5 and Figure 6 As shown, the inner sides of the four connecting cylinders 43 are rotatably connected to the connecting disks 61, the inner ends of the four connecting columns 51 are embedded with the rotating disks 63, the inner sides of the four rotating disks 63 are respectively connected to the outer sides of the four connecting disks 61 with support springs 62, the support springs 62 are used to make the connecting columns 51 move better, the outer sides of the four connecting columns 51 are opened with spiral grooves 65, the outer sides of the inner tops of the four connecting cylinders 43 are fixed with balls 64, the four balls 64 are respectively located in the four spiral grooves 65, when the connecting column 51 drives the spiral grooves 65 to move, the balls 64 can drive the spiral grooves 65 to rotate.

[0038] The self-locking mechanism 7 includes a mounting frame 71, a rotating shaft 72, a rotating frame 73, a driven wheel 74, a first ratchet wheel 75, a pressure rod 76 and a first torsion spring 77. Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the outer sides of the four connecting columns 51 are fixedly mounted with a rotating frame 73, the inner sides of the outer bottoms of the four connecting cylinders 43 are fixedly connected with mounting frames 71, the two sides of the four mounting frames 71 are rotatably connected with rotating shafts 72, the outer sides of the four rotating shafts 72 are fixedly mounted with driven wheels 74, when the rotating frame 73 is reversed and moves outward to contact the driven wheels 74, the driven wheels 74 can limit the rotating frame 73, the outer sides of the four rotating shafts 72 are fixedly mounted with first ratchet wheels 75, the first ratchet wheels 75 are located on the outer sides of the driven wheels 74, the outer sides of the four mounting frames 71 are rotatably connected with pressure rods 76, the tail ends of the four pressure rods 76 are respectively meshed with the four first ratchet wheels 75, and the rotation points between the four pressure rods 76 and the four mounting frames 71 are connected with first torsion springs 77.

[0039] Initially, the support spring 62 is in a compressed state. When people pull the display screen to rotate, the rotation of the display screen drives the rotating seat 52 to rotate, the rotation of the rotating seat 52 drives the connecting column 51 to rotate, the rotation of the connecting column 51 drives the spiral groove 65 to rotate, the spiral groove 65 rotates and swings outward through the ball 64, the spiral groove 65 moves outward and drives the turntable 63 to move outward, the outward movement of the turntable 63 causes the support spring 62 to continuously extend, due to the action of the support spring 62, the turntable 63 can better drive the connecting column 51 to move outward, when the display screen is reversed to a suitable angle, stop pulling the display screen to rotate, the display screen stops driving the connecting column 51 to rotate through the rotating seat 52, the connecting column 51 stops driving the spiral groove 65 to rotate, the spiral groove 65 stops moving outward through the ball 64, and then you can start viewing the information displayed on the display screen. When the display screen needs to be reset, the display screen is pulled to rotate in the opposite direction, and the connecting column 51 is driven to rotate in the opposite direction through the rotating seat 52. The connecting column 51 rotates in the opposite direction and drives the spiral groove 65 to rotate in the opposite direction. The spiral groove 65 rotates in the opposite direction and moves inwards through the ball 64 to reset. The inward movement and reset of the spiral groove 65 drives the connecting column 51 to move inwards and reset. The inward movement and reset of the connecting column 51 drives the rotating disk 63 to move inwards and reset. The reset of the rotating disk 63 compresses and resets the supporting spring 62. In this way, the display screen can be moved inwards and outwards at the same time as the angle is adjusted, and there is no need to adjust them separately, which is more convenient.

[0040] When the connecting column 51 rotates and moves outward, the connecting column 51 drives the rotating frame 73 to rotate and move outward, and the rotating frame 73 rotates and moves outward to contact the driven wheel 74. Due to the limiting effect of the pressure rod 76 on the first ratchet 75, the first ratchet 75 cannot rotate, and the first ratchet 75 makes the rotating shaft 72 unable to rotate, and the rotating shaft 72 makes the driven wheel 74 unable to rotate, and the driven wheel 74 limits the rotating frame 73. The limiting of the rotating frame 73 makes the connecting tube 43 stop rotating, and the display screen cannot rotate. At this time, it means that the display screen has moved outward to the maximum stroke. When people pull the display screen to reverse and reset and move inward, the connecting column 51 moves inward to reset and drives the rotating frame 73 to move inward to reset, and the rotating frame 73 moves inward to disengage from the driven wheel 74, and stops pulling the display screen to rotate in the opposite direction. In this way, people can be reminded that the display screen has moved outward to the maximum stroke, and the display screen is prevented from continuing to move outward, causing the connecting column 51 and the connecting tube 43 to separate.

[0041] Example 3

[0042] On the basis of the embodiment 1 and the embodiment 2, a rotation auxiliary mechanism 8 is further included. The rotation auxiliary mechanism 8 includes a second ratchet 81, a limit rod 82 and a second torsion spring 83. Figure 1 , Figure 2 , Fig. 9 and Fig.10As shown, one side of the four fixed rods 42 is fixedly mounted with a second ratchet 81, and the four connecting tubes 43 are rotatably connected to the limiting rod 82 near the outer side of the fixed rod 42. The tail ends of the four limiting rods 82 are respectively engaged with the four second ratchet wheels 81. The limiting rod 82 is used to limit the reverse rotation of the second ratchet wheels 81, and the rotation point between the four limiting rods 82 and the four connecting tubes 43 is connected with a second torsion spring 83.

[0043] When the display screen needs to be pulled to swing upward, the limiting rod 82 is first pulled to swing outward and disengage from the second ratchet 81, the second torsion spring 83 is compressed, and then the display screen is pulled to swing up and down, which makes the connecting tube 43 swing up and down and rotate on the fixing rod 42. At the same time, the connecting tube 43 also drives the limiting rod 82 to swing up and down. When the display screen swings up and down to adjust the angle, the limiting rod 82 is released. Due to the action of the second torsion spring 83, the limiting rod 82 swings inward and resets to engage with the second ratchet 81. The second ratchet 81 limits the limiting rod 82, and also limits the connecting tube 43. In this way, the display screen can be prevented from swinging downward to affect people's viewing of information.

[0044] Finally, it is necessary to point out that the above content is only used to help understand the technical solution of the present invention and cannot be understood as limiting the scope of protection of the present invention; non-essential improvements and adjustments made by technical personnel in the field of technology based on the above content of the present invention are all within the scope of protection required by the present invention.
