DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-5 A display that is easy to use includes a display body 1 and an adjustment device 100 connected to the display body 1. The adjustment device 100 includes a box body 2 with an opening on one side, and the opening of the box body 2 is arranged toward the display body 1. The box body 2 is rollingly connected to the back of the display body 1. A vertical plate 26 is fixedly connected to the side of the box body 2 away from the display body 1, and a base 27 is fixedly connected to the lower end of the vertical plate 26. The box body 2 maintains this fixed height position through the vertical plate 26 and the base 27, and the deflection angle and the pitch angle of the display body 100 are adjusted by the adjustment device 100.

[0024] Specifically, the rolling connection is that a rolling sleeve 3 is fixedly connected to the back of the display body 1, a spherical groove is provided in the rolling sleeve 3, a fixed ball 4 is rollingly connected in the spherical groove, a connecting rod 5 is integrally formed at one end of the fixed ball 4, and the end of the connecting rod 5 away from the fixed ball 4 is fixedly connected to the box body 2, and a movable groove 6 is provided on the side of the rolling sleeve 3 close to the box body 2, and the inner diameter of the opening of the movable groove 6 is smaller than the diameter of the fixed ball 4. The position of the box body 2, the connecting rod 5, and the fixed ball 4 will not change, and the rolling sleeve 3 can only be driven to roll by the display body 1, and the rolling sleeve 3 rolls relative to the fixed ball 4, and the movable groove 6 can move in any direction relative to the connecting rod 5. The movable groove 6 is a truncated cone structure, which can limit the extreme movable position of the connecting rod 5.

[0025] A first transmission cavity 7 and four second transmission cavities 8 are provided in the box body 2. The four second transmission cavities 8 are evenly distributed about the circumference of the first transmission cavity 7. A motor 9 is embedded in the inner wall of the first transmission cavity 7. The output end of the motor 9 is coaxially fixedly connected with a first bevel gear 10. Correspondingly, the first bevel gear 10 is circumferentially meshed with four second bevel gears 11, and the positions of the four second bevel gears 11 correspond one by one to the positions of the four second transmission cavities 8. A horizontal shaft 12 is splined at one end of each second bevel gear 11 away from the first bevel gear 10. The motor 9 transmits torque to each horizontal shaft 12 through the first bevel gear 10 and the second bevel gear 11 meshing with each other.

[0026] The above-mentioned spline connection is specifically that the cross-section of the part of the horizontal shaft 12 located in the first transmission chamber 7 is square, and a spline groove 22 slidingly connected to the horizontal shaft 12 is opened on one side of the second bevel gear 11. The square-structured horizontal shaft 12 and the spline groove 22 can transmit torque, and other structures with limiting functions can also be adopted, such as regular polygons. A permanent magnet block 23 is fixedly installed on the inner wall of the spline groove 22, and an electromagnetic block 24 is embedded at one end of the horizontal shaft 12, and the permanent magnet block 23 and the electromagnetic block 24 are magnetically matched. A spring 25 is fixedly connected to the inner wall of the spline groove 22 and one end of the horizontal shaft 12. The magnetic attraction of the electromagnetic block 24 and the permanent magnet block 23 is used to compress the spring 25, thereby driving the second bevel gear 11 to move in a direction away from the first bevel gear 10, so that the two are separated.

[0027] Furthermore, the diameter of the spring 25 is larger than the maximum width of the permanent magnet block 23 and the electromagnetic block 24. When the spring 25 is compressed, the permanent magnet block 23 and the electromagnetic block 24 will not affect the expansion and contraction of the spring 25. The spring 25 is made of non-magnetic material to avoid the magnetic influence of the spring 25 on the permanent magnet block 23.

[0028] One end of each horizontal shaft 12 away from the second bevel gear 11 passes through the interlayer between the first transmission chamber 7 and the second transmission chamber 8, extends into the second transmission chamber 8 and is coaxially fixedly connected with the third bevel gear 13. A threaded rod 15 is rotatably connected to the inner wall of each second transmission chamber 8, and the axis of the threaded rod 15 is vertically staggered with the axis of the horizontal shaft 12. The thread rotation direction of every two relatively arranged threaded rods 15 is the same. Since the rotation directions of the two relatively arranged second bevel gears 11 / threaded rods 15 are opposite, then on the basis of the same thread rotation direction of the two threaded rods 15, one of the sleeve rods 17 will move axially toward the display body 1, and the other will move axially away from the display body 1.

[0029] The threaded rod 15 is coaxially fixedly connected with a fourth bevel gear 14 meshing with the third bevel gear 13. The horizontal shaft 12 transmits torque to the threaded rod 15 through the third bevel gear 13 and the fourth bevel gear 14 meshing with each other. A sleeve rod 17 is threadedly sleeved on the threaded rod 15. One end of the sleeve rod 17 is provided with a thread groove 16 threadedly connected with the threaded rod 15. The end of the sleeve rod 17 away from the threaded rod 15 passes through the second transmission chamber 8. The inner wall of the second transmission chamber 8 is provided with a sliding groove 18, and the sliding groove 18 is square. The sleeve rod 17 is a structure with an inner circle and an outer square. The sliding groove 18 and the sleeve rod 17 are provided with a limit condition through sliding cooperation. The upper end of the sleeve rod 17 is fixedly connected with a limit pin 21. The back of the display body 1 is fixedly connected with a fixing plate 19. The fixing plate 19 is provided with a waist groove 20 which is limitedly slidably connected with the limit pin 21. The movement compensation is performed through the sliding cooperation between the limit pin 21 and the waist groove 20. The upper end of the limit pin 21 is fixedly connected with a limit ring, and the outer diameter of the limit ring is greater than the width of the waist groove 20. The limit ring can effectively prevent the limit pin 21 from being separated from the waist groove 20.

[0030] When using the present invention, when the two second bevel gears 11 arranged opposite to each other are meshed with the first bevel gear 10, the motor 9 transmits the torque to the horizontal shaft 12 through the mutually meshing first bevel gear 10 and the second bevel gear 11, and the horizontal shaft 12 transmits the torque to the threaded rod 15 through the mutually meshing third bevel gear 13 and the fourth bevel gear 14. During the rotation of the threaded rod 15, the sleeve rod 17 is limited by the sliding groove 18 and moves axially. It should be noted that since the two second bevel gears 11 are arranged opposite to each other and the thread rotation directions of the two corresponding threaded rods 15 are the same, the two corresponding sleeve rods 17 slide with the waist groove 20 through the limit pin 21, which shows that one moves axially toward the display body 1 and the other moves axially away from the display body 1, so that the display body 1 rotates around its own bisector until it reaches the required position, and the deflection angle or the pitch angle can be adjusted.

[0031] The above is the working principle of angle adjustment. The skew angle and the pitch angle can be adjusted simultaneously or individually. However, it should be noted that after the required angle adjustment is completed, the second bevel gear 11 needs to be out of mesh with the first bevel gear 10.

[0032] The principle of how the second bevel gear 11 engages or does not engage with the first bevel gear 10 is as follows: when the second bevel gear 11 engages with the first bevel gear 10, the spring 25 is in a normal state, the permanent magnet block 23 and the electromagnetic block 24 do not affect each other, and the electromagnetic block 24 is in a power-off state; when the second bevel gear 11 engages with the first bevel gear 10, the electromagnetic block 24 is in a power-on state, the electromagnetic block 24 generates a magnetic attraction force on the permanent magnet block 23, and the spring 25 is forced to compress, thereby pulling the second bevel gear 11 in a direction away from the first bevel gear 10, so that the two are separated. At this time, the second bevel gear 11 is not affected by the rotating first bevel gear 10.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
