[0034] In addition, the technical features involved in the different embodiments of the utility model described below can be combined with each other as long as there is no conflict between them.
[0035] As Figure 1 The embodiment provides a pitch rotation adjusting support 29, which comprises a first fixing part 1 connected with a display screen 27, for example, the first fixing part 1 can be a rectangular plate structure;A second fixing part 2 connected with a host computer 28, for example, the second fixing part 2 can be a rectangular plate structure, and the end of the second fixing part 2 away from the first fixing part 1 can be designed as a semicircle;A pitch adjusting mechanism 3, the first fixing part 1 is connected with the second fixing part 2 through the pitch adjusting mechanism 3, so that the pitch included angle between the first fixing part 1 and the second fixing part 2 can be adjusted by the pitch adjusting mechanism 3;A rotation adjusting mechanism 4, the second fixing part 2 is connected with the host computer 28 through the rotation adjusting mechanism 4, so that the second fixing part 2 can rotate relative to the host computer 28.
[0036] As Figure 2 The embodiment provides a pitch rotation adjusting support 29, which comprises a first fixing part 1 connected with a display screen 27, for example, the first fixing part 1 can be a rectangular plate structure;A second fixing part 2 connected with a host computer 28, for example, the second fixing part 2 can be a rectangular plate structure, and the end of the second fixing part 2 away from the first fixing part 1 can be designed as a semicircle;A pitch adjusting mechanism 3, the first fixing part 1 is connected with the second fixing part 2 through the pitch adjusting mechanism 3, so that the pitch included angle between the first fixing part 1 and the second fixing part 2 can be adjusted by the pitch adjusting mechanism 3;A rotation adjusting mechanism 4, the second fixing part 2 is connected with the host computer 28 through the rotation adjusting mechanism 4, so that the second fixing part 2 can rotate relative to the host computer 28.
[0037] The pitch adjusting mechanism 3 comprises a first damping ring 6, a second damping ring 7 and a long rotating shaft 5. The first fixing member 1 is provided with a support groove 11, and the second fixing member 2 is provided with a hinge support 12 which is accommodated in the support groove 11 so that the first fixing member 1 and the second fixing member 2 can rotate relative to each other. The first damping ring 6 and the second damping ring 7 are respectively located at two ends of the hinge support 12. The long rotating shaft 5 sequentially passes through the first damping ring 6, the hinge support 12 and the second damping ring 7, and the end of the long rotating shaft 5 at least partially extends into the first fixing member 1, so that the long rotating shaft 5 and the first fixing member 1 become an integral whole. The long rotating shaft 5 applies a pressure to the first damping ring 6 which is parallel to the axial direction of the long rotating shaft 5, so that the first damping ring 6 is pressed against the hinge support 12. When the first fixing member 1 rotates relative to the second fixing member 2, the friction between the first damping ring 6 and the hinge support 12 can be used as a damping torque, so that a damping feeling is generated when the first fixing member 1 rotates relative to the second fixing member 2. Similarly, the long rotating shaft 5 applies a pressure to the second damping ring 7 which is parallel to the axial direction of the long rotating shaft 5, so that the second damping ring 7 is pressed against the first fixing member 1. When the first fixing member 1 rotates relative to the second fixing member 2, the friction between the second damping ring 7 and the groove wall of the support groove 11 can be used as a damping torque, so that a damping feeling is generated when the first fixing member 1 rotates relative to the second fixing member 2. In this way, the first fixing member 1 can be arbitrarily hovered when the pitch adjusting is performed relative to the second fixing member 2.
[0038] As Figure 3 , Figure 4As shown in the drawings, the first fixed part 1 is provided with a first hanging ear 8 and a second hanging ear 9 at intervals, and the area between the first hanging ear 8 and the second hanging ear 9 forms the support groove 11; the inner side wall of the ear hole 10 of the first hanging ear 8 is provided with a first rotation stopping groove 17, and the outer side wall of the first damping ring 6 is provided with a first rotation stopping key 18; the first damping ring 6 is arranged in the ear hole 10 of the first hanging ear 8, and the first rotation stopping key 18 is located in the first rotation stopping groove 17, so that the first damping ring 6 can move in the direction of the long rotating shaft 5 but cannot rotate in the ear hole 10. The first damping ring 6 is at least partially exposed outside the first hanging ear 8 and abuts against the hinge support 12, for example, one end of the first damping ring 6 close to the hinge support 12 is exposed and abuts against the end face of the hinge support 12 away from the second damping ring 7. The end of the hinge support 12 away from the first hanging ear 8 is provided with a containing groove 19, the inner side wall of the containing groove 19 is provided with a second rotation stopping groove 20, and the outer side wall of the second damping ring 7 is provided with a second rotation stopping key 21; the second damping ring 7 is arranged in the containing groove 19, and the second rotation stopping key 21 is located in the second rotation stopping groove 20, so that the second damping ring 7 can move in the direction of the long rotating shaft 5 but cannot rotate in the containing groove 19. The second damping ring 7 is at least partially exposed outside the containing groove 19 and abuts against the second hanging ear 9, for example, one end of the second damping ring 7 away from the hinge support 12 is exposed and abuts against the side of the second hanging ear 9 facing the hinge support 12.
[0039] The end of the long rotating shaft 5 is screwed into the ear hole 10 of the second hanging ear 9 and is threadedly connected with the second hanging ear 9, so that the pressure applied to the first damping ring 6 and the second damping ring 7 can be adjusted by screwing the long rotating shaft 5. In this way, by adjusting the torque of the long rotating shaft 5, the normal pressure of the contact surfaces of the first damping ring 6 and the hinge support 12 and the second damping ring 7 and the second hanging ear 9 can be adjusted, that is, the friction between the contact surfaces can be adjusted, and the damping torque during pitching can be adjusted, so as to achieve various damping feelings and meet the hovering of various angles of various weight display screens 27. For example, when the weight of the display screen 27 is large, the long rotating shaft 5 can be tightened to increase the damping torque. For example, when the weight of the display screen 27 is small, the long rotating shaft 5 can be loosened to reduce the damping torque.
[0040] The first damping ring 6 and the second damping ring 7 are both damping rings made of plastic material, and the first fixed part 1 and the second fixed part 2 are both fixed parts made of metal material. In this way, compared with damping rings made of metal material, the debris generated by friction can be prevented, and the noise generated by the friction between metals during pitching adjustment can be avoided.
[0041] As Figure 5 , Figure 6 ,Figure 7 and Figure 8 As shown in the figure, the rotation adjusting mechanism 4 comprises a rotation limiting piece 14, a main machine connecting piece 13 and a damping washer 15; the rotation limiting piece 14 is arranged on the lower end surface of the second fixing piece 2, for example, the rotation limiting piece 14 can be arranged on the lower end surface of the end of the second fixing piece 2 away from the first fixing piece 1. The main machine connecting piece 13 is arranged between the second fixing piece 2 and the rotation limiting piece 14, and the main machine connecting piece 13 is used for fixed connection with the main machine 28; the damping washer 15 is arranged between the main machine connecting piece 13 and the second fixing piece 2 and between the main machine connecting piece 13 and the rotation limiting piece 14. For example, the rotation limiting piece 14 can be a T-shaped annular structure as a whole, the main machine connecting piece 13 is an annular structure, and the smaller diameter part of the rotation limiting piece 14 can be inserted into the circular hole in the middle of the main machine connecting piece 13 and connected with the second fixing piece 2 above. For example, the upper end surface and the lower end surface of the main machine connecting piece 13 are both provided with a washer groove 22, and the groove bottom of the washer groove 22 is provided with a positioning hole 23; one side of the damping washer 15 facing the main machine connecting piece 13 is provided with a positioning column 24, the damping washer 15 is arranged in the washer groove 22, and the positioning column 24 is inserted into the positioning hole 23 to limit the rotation of the damping washer 15 relative to the main machine connecting piece 13. In this way, the second fixing piece 2 and the rotation limiting piece 14 form a whole, and when the second fixing piece 2 and the rotation limiting piece 14 rotate relative to the main machine connecting piece 13, the frictional force between the upper damping washer 15 and the lower end surface of the second fixing piece 2 and the lower damping washer 15 and the rotation limiting piece 14 can be used as damping torque, so as to produce damping feeling when the second fixing piece 2 rotates relative to the main machine 28, and realize arbitrary hovering of the second fixing piece 2 when rotating relative to the main machine 28.
[0042] The rotation limiting piece 14 and the second fixing piece 2 are connected through a screw 16, so as to adjust the pressure on the damping washer 15 by rotating the screw 16. For example, the rotation limiting piece 14 and the second fixing piece 2 can be connected through three screws 16 arranged at intervals. In this way, by adjusting the torque of the screw 16, the normal pressure of the contact surface between the upper damping washer 15 and the lower end surface of the second fixing piece 2 and the lower damping washer 15 and the rotation limiting piece 14 can be adjusted, that is, the frictional force between the contact surfaces can be adjusted, that is, the damping torque during rotation can be adjusted, so as to achieve various damping feelings and meet the random stop at various angles.
[0043] The damping gasket 15 is made of plastic material, the rotation limiting piece 14 is made of metal material, and the main machine connecting piece 13 is made of metal material. In this way, compared with the damping gasket 15 made of metal material, the debris generated by friction can be prevented, and the noise generated by friction between metals during rotation adjustment can be avoided.
[0044] According to the needs, a limiting structure of a required rotation angle can be added between the second fixing piece 2 and the main machine connecting piece 13 or between the rotation limiting piece 14 and the main machine connecting piece 13, so as to meet the customization of the rotation angle. For example, a limiting block 25 can be arranged on the side wall of the rotation limiting piece 14, and a limiting groove 26 can be arranged on the lower end surface of the main machine connecting piece 13. When the limiting block 25 abuts against the groove wall of the limiting groove 26, the rotation limiting piece 14 cannot continue to rotate relative to the main machine connecting piece 13. Similarly, the rotation stop position can be increased, and each stop position corresponds to a certain angle of rotation, which is a form of limiting.
[0045] According to the needs, a limiting structure of a required rotation angle can be added between the second fixing piece 2 and the main machine connecting piece 13 or between the rotation limiting piece 14 and the main machine connecting piece 13, so as to meet the customization of the rotation angle. For example, a limiting block 25 can be arranged on the side wall of the rotation limiting piece 14, and a limiting groove 26 can be arranged on the lower end surface of the main machine connecting piece 13. When the limiting block 25 abuts against the groove wall of the limiting groove 26, the rotation limiting piece 14 cannot continue to rotate relative to the main machine connecting piece 13. Similarly, the rotation stop position can be increased, and each stop position corresponds to a certain angle of rotation, which is a form of limiting.
[0046] As shown in Figure 9 , Figure 10 and Figure 11 Another embodiment provides a display device, which comprises the tilt-rotation adjustment support 29 described in any one of the above embodiments, and further comprises a display screen 27 and a main machine 28. The display screen 27 is connected with the first fixing piece 1, and the main machine 28 is connected with the second fixing piece 2. The display screen 27 can be a display screen 27 on a medical device or a display screen 27 on other devices. During use, the display screen 27 can be adjusted in tilt angle and rotation relative to the main machine 28.
[0047] The tilt-rotation adjustment support 29 and the main machine 28 can be connected in an integrated manner or in a separated manner. When the main machine 28 is connected in a separated manner, the fixation of the main machine connecting piece 13 needs to be considered.
[0048] The main machine connecting piece 13 can be adjusted in size and shape according to the needs, and can be fixed with the main machine 28 or a workbench separately. The first fixing piece 1 can be adjusted in size and shape according to the installation size of the display screen 27.
[0049] In summary, the pitch rotation adjusting support 29 in the application can make the display screen 27 keep damping arbitrary hovering when pitching, the angle can be adjusted to the horizontal direction, the rotation adjusting can make the display screen 27 rotate to an arbitrary angle and keep damping hovering, the angle limit or gear position can be increased according to the need, the damping of the pitch and rotation adjusting mechanism 4 can be adjusted according to the use, the mechanism has small volume, simple structure, convenient installation and adjustment, and more beautiful appearance.
[0050] The display device in the application can realize the adjustment of the pitch angle of the display screen 27 according to the need, can adjust the horizontal state to be attached to the host 28 or the workbench, and can increase the limit or gear position according to the need.
[0051] The display device in the application can realize the adjustment of the rotation angle of the display screen 27 according to the need, the angle can be arbitrarily adjusted, and the limit or gear position can be increased according to the need.
[0052] Obviously, the above embodiments are only examples for clearly illustrating, and are not the limitation of the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments cannot be exhausted, and the obvious changes or variations still fall within the protection scope of the application.
