[0041] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0042] As described in the background, the display screen of a medical device needs to rotate flexibly and remain stable during use, allowing medical staff to adjust the viewing angle according to their needs. However, the hinges connecting the display screen to the traditional medical device present numerous problems. For example, they suffer from poor stability. After the display screen is rotated to the desired viewing angle, the damping provided by the hinges is insufficient to securely hold the display screen in place, causing it to shake or suddenly fall during viewing. Furthermore, due to the inherent structural characteristics of existing hinges, they are unable to bear large weights. When the weight exceeds a certain value, the hinges are prone to deformation or even breakage.

[0043] Based on the above problems, an embodiment of the present invention provides a hinge and a medical host. The hinge is installed on the medical host, and the display screen is connected to the hinge. The hinge can provide sufficient damping to ensure the stability of the display screen. At the same time, it can also bear a large weight to avoid deformation or breakage of the hinge. The hinge will be described in detail below.

[0044] Please refer to Figures 1 to 3 The hinge includes a core rod 1, a cover fixing plate 2, and a damping assembly 3. The core rod 1 includes a retaining ring 14. The cover fixing plate 2 is sleeved on the core rod 1 and can rotate around the core rod 1. The cover fixing plate 2 and the retaining ring 14 are in surface contact with each other. The cover fixing plate 2 is used to mount a display screen, and the damping assembly 3 is disposed on the core rod 1. When the damping assembly 3 applies pressure to the cover fixing plate 2 and presses the cover fixing plate 2 against the retaining ring 14, the surface contact between the cover fixing plate 2 and the retaining ring 14 creates a huge friction, which fixes the position of the cover fixing plate 2, thereby firmly fixing the display screen at the desired viewing angle. The hinge can provide sufficient damping as needed to keep the display screen stable during use and prevent the display screen from shaking or suddenly falling.

[0045] refer to Figure 4 and Figure 5 The core rod 1 includes a first portion 11, a second portion 12, and a third portion 13 connected in sequence. The first portion 11 is directly or indirectly fixedly connected to the main unit, and the third portion 13 is used to mount the cover fixing plate 2 and the damping assembly 3. The first portion 11, the second portion 12, and the third portion 13 are all cylindrical. The outer walls of the first portion 11 and the third portion 13 are each provided with a rotation-stopping surface 15. The diameter of the second portion 12 is larger than the diameters of the first portion 11 and the third portion 13. A retaining ring 14 is provided at the junction of the second portion 12 and the third portion 13.

[0046] In this embodiment, the hinge further comprises a base fixing frame 4, the first portion 11 of the core rod 1 is connected to the base fixing frame 4, and the base fixing frame 4 is further connected to the medical host. Figure 6The base fixing frame 4 is an angular plate, including a connecting portion and a plug-in portion that are perpendicular to each other. The connecting portion is provided with a screw hole, and is connected to the medical host by installing a screw in the screw hole; the plug-in portion is provided with a socket, and the shape and size of the socket match the first portion 11 of the core rod 1. When the first portion 11 of the core rod 1 is plugged into the socket, the anti-rotation surface 15 on the first portion 11 can prevent the entire core rod 1 from rotating in the socket, ensuring a stable connection between the core rod 1 and the base fixing frame 4. At the same time, the connection method between the core rod 1 and the base fixing frame 4 can significantly improve the bearing capacity of the entire hinge. This is because when the display screen is installed on the face cover fixing plate 2 and the face cover fixing plate 2 is firmly set on the third portion 13 of the core rod 1, the weight of the display screen is overcome by the torsion of the core rod 1, and the core rod 1 is fixedly connected to the base fixing frame 4, thereby improving the bearing capacity of the entire hinge.

[0047] refer to Figure 7 The cover fixing plate 2 includes a rotating connection portion 21 and a mounting portion 22. The rotating connection portion 21 and the mounting portion 22 are integrally formed to ensure the strength and load-bearing capacity of the structure. The rotating connection portion 21 is annular and is mounted on the third portion 13 of the core rod 1. One end of the mounting portion 22 is connected to the rotating connection portion 21. The mounting portion 22 is provided with a slot for clamping the display screen and a connecting screw hole. The display screen can be connected to the mounting portion 22 via screws or bolts.

[0048] refer to Figure 8 In order to limit the rotation range of the cover fixing plate 2 and allow the display screen to be adjusted within a certain range, a limit stop 211 is provided on the end surface of the rotating connection portion 21. Correspondingly, an angle adjustment gasket 35 is sleeved between the retaining ring 14 and the rotating connection portion 21. A limit groove 351 is provided on the circumferential wall of the angle adjustment gasket 35. The limit groove 351 corresponds to the limit stop 211. The limit stop 211 can slide along the limit groove 351, and the limit groove 351 limits the sliding range of the limit stop 211, thereby limiting the rotation range of the entire cover fixing plate 2. It is worth mentioning that when the angle adjustment gasket 35 is sleeved on the third portion 13 of the core rod 1, the sleeve hole of the angle adjustment gasket 35 matches the shape of the third portion 13, and the angle adjustment gasket 35 will not rotate relative to the third portion 13. In other embodiments, the limit groove 351 can also be directly provided on the circumferential wall of the retaining ring 14.

[0049] Optionally, a filling hole is further provided on the end surface of the rotary connection portion 21 and / or the angle adjustment gasket 35 , and the filling hole is filled with a solid lubricant.

[0050] Reference again Figure 3The damping assembly 3 includes a locking member 31, which applies pressure to the rotational connection portion 21 of the face cover fixing plate 2, thereby securing the face cover fixing plate 2. In this embodiment, the locking member 31 is a locking nut. The outer wall of the third portion 13 of the core rod 1 is provided with external threads, and the locking nut is threadedly connected to the third portion 13. When the locking nut is turned toward the retaining ring 14, it squeezes the face cover fixing plate 2 until it is pressed against the angle adjustment washer 35. The friction between the locking nut and the angle adjustment washer 35 stabilizes the locking of the face cover fixing plate 2.

[0051] Furthermore, the third portion 13 is fitted with an oil-collecting gasket 32, which is located between the cover fixing plate 2 and the locking member 31. One side surface of the oil-collecting gasket 32 ​​is in contact with the end surface of the rotating connection portion 21 of the cover fixing plate 2. The oil-collecting gasket 32 ​​is used to reduce friction between the rotating connection portion 21 and the locking member 31. The oil-collecting gasket 32 ​​is made of a polymer composite material to withstand high-intensity torsional forces, thereby increasing the service life of the hinge. Of course, when the oil-collecting gasket 32 ​​is fitted onto the third portion 13 of the core rod 1, the shape and size of the through hole in the middle of the oil-collecting gasket 32 ​​match those of the third portion 13, and the oil-collecting gasket 32 ​​will not rotate relative to the third portion 13.

[0052] refer to Figure 9 and Figure 10 The damping assembly 3 also includes an anti-loosening gasket 33, which is sleeved on the core rod 1 and arranged between the oil-collecting gasket 32 ​​and the locking member 31. The anti-loosening gasket 33 prevents the locking nut from loosening under the torsional force transmitted by the oil-collecting gasket 32.

[0053] The sidewall of the anti-loosening washer 33, located near the oil-collecting washer 32, is equipped with a rotation-stopping protrusion 331. This protrusion 331 increases friction and prevents rotation. The other sidewall of the anti-loosening washer 33 is also equipped with a circle of rotation-stopping protrusions 332. These protrusions 332 are arranged in a stepped pattern. When the locking nut and the anti-loosening washer 33 are engaged, the locking nut can only rotate in one direction, and the direction of this rotation is consistent with the direction of the locking surface cover fixing plate 2. Of course, when the anti-loosening washer 33 is mounted on the third portion 13 of the core rod 1, it also matches the shape and size of the third portion 13, and the anti-loosening washer 33 itself will not rotate relative to the core rod 1.

[0054] Furthermore, the damping assembly 3 also includes an elastic gasket group 34, which is arranged between the anti-loosening gasket 33 and the oil-collecting gasket 32. The elastic gasket group 34 transmits axial pressure to the cover fixing plate 2 while also providing high-intensity torsional force, further ensuring the stability of the cover fixing plate 2. The elastic gasket group 34 includes a plurality of overlapping arched gaskets 341, each of which has a through circular hole in the middle. The plurality of arched gaskets 341 are sleeved on the third portion 13 of the core rod 1 through the circular hole. The circular hole in the middle of the arched gasket 341 allows the arched gasket 341 to release stress by rotation under high-intensity extrusion, thereby preventing the arched gasket 341 from fatigue and failure in transmitting torsional force.

[0055] In this embodiment, the damping assembly 3 includes a locking nut, an oil-collecting washer 32, an anti-loosening washer 33, and an elastic washer group 34. In other embodiments, the damping assembly 3 can also be implemented by using a spring, a hydraulic cylinder, a pneumatic cylinder, etc.

[0056] Existing cables connecting displays and consoles typically need to be routed along the edge of the hinge. This routing not only increases the difficulty of cable installation, but also easily damages the cables due to repeated bending and friction, affecting signal transmission. To address this, the core rod 1 in this embodiment has an axially oriented channel 16 formed inside. Channel 16 runs through both ends of the core rod 1, allowing cables to be routed along channel 16 within the core rod 1. This creates an aesthetically pleasing design and effectively prevents bending and wear of the cables. Furthermore, it reduces the weight of the entire hinge without affecting the load-bearing capacity of the core rod 1.

[0057] In this embodiment, the core rod 1 and the cover fixing plate 2 are made of high-strength, wear-resistant and lightweight materials, such as carbon fiber or stainless steel, to further increase the bearing capacity of the hinge and ensure that it can stably carry a display screen weighing at least 2.5 kg.

[0058] The hinge of the embodiment of the present invention can provide both a large load-bearing capacity and sufficient damping, thereby ensuring that the display screen can be stably mounted on the cover fixing plate 2 .

[0059] An embodiment of the present utility model further provides a medical host comprising the above-mentioned hinge.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
