The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

Referring to fig. 1, an ultrasonic diagnostic apparatus according to an embodiment of the present invention includes: display screen 11 assembly, base assembly and locking assembly.

The display screen 11 assembly includes a display screen 11 and a housing 12. The front side of the display screen 11 is a display surface for displaying image information. The display screen 11 is provided in the housing 12 to protect the display screen 11 with the housing 12.

In some embodiments, the housing 12 includes a screen housing 121 and a mount 122. The display screen 11 is disposed in the screen housing 121, and the display screen 11 is protected by the screen housing 121. The screen housing 121 is rotatably mounted on the mounting seat 122, and thus the screen housing 121 can rotate around the mounting seat 122 to adjust the angle of the display screen 11.

In some embodiments, the screen housing 121 is rotatably connected to the mounting base 122 through the first rotating member 1211, so that the screen housing 121 can rotate up and down relative to the mounting base 122 to adjust the angle of the display screen 11 in the vertical direction.

It is understood that in other embodiments, the screen housing 121 can also be horizontally rotated relative to the mounting seat 122 to adjust the angle of the display screen 11 in the horizontal direction. The screen housing 121 may also rotate about an inclined axis relative to the mount 122.

In some embodiments, the first rotating member 1211 is a damping rotating shaft, and when the screen housing 121 is rotated, the damping rotating shaft provides a resistance force that enables the screen housing 121 to rotate more smoothly and to be fixed at any position.

Still referring to fig. 1, the base assembly is used for supporting the display screen 11 assembly and adjusting the height and angle of the display screen 11 assembly. Specifically, the base assembly includes a base 21, a lower arm 22, and an upper arm 23 connected to each other. The base 21 serves as a bottom support, one end of the lower arm 22 is rotatably connected to the base 21, and one end of the upper arm 23 is rotatably connected to the other end of the lower arm 22. The display screen 11 assembly is rotatably connected to the other end of the upper arm 23 through the mounting seat 122, so that the height and angle of the display screen 11 assembly can be adjusted by rotating the lower arm 22 and the upper arm 23.

It should be noted that, since the base 21 serves as a common bottom support for the base assembly and the display screen 11 assembly, the height and angle of the display screen 11 assembly are adjusted, that is, the position of the display screen 11 assembly relative to the base 21 is changed.

In some embodiments, the lower arm 22 is disposed in an inclined manner, the lower end of the lower arm 22 is rotatably connected to the base 21 through a first rotating shaft 221, the first rotating shaft 221 extends vertically, and the lower arm 22 can rotate in a horizontal direction around the first rotating shaft 221, so that an angle of the lower arm 22 relative to the base 21 in the horizontal direction is changed to adjust an angle of the display screen 11 assembly in the horizontal direction.

In other embodiments, the first shaft 221 may be disposed at an angle so that the lower arm 22 can rotate around an inclined plane perpendicular to the axis of the first shaft 221.

Referring to fig. 1 and 2, in some embodiments, the end of the upper arm 23 connected to the upper end of the lower arm 22 is a first end, and the other end of the upper arm 23 connected to the mounting seat 122 is a second end. The upper arm 23 is hinged at a first end to the upper end of the lower arm 22, and the upper arm 23 can pivot about its first end and raise or lower its second end. When the upper arm 23 rotates to raise the second end, the included angle between the upper arm 23 and the lower arm 22 is increased, and the second end can drive the display screen 11 assembly to raise, so that the height of the display screen 11 assembly relative to the base 21 is raised. When the upper arm 23 rotates and the second end descends, the included angle between the upper arm 23 and the lower arm 22 becomes smaller, that is, the upper arm 23 rotates to fold with the lower arm 22, and the second end can drive the display screen 11 assembly to descend, so that the height of the display screen 11 assembly relative to the base 21 is reduced. So that the height of the display screen 11 assembly can be adjusted by rotating the upper arm 23.

In some embodiments, the first end of the upper arm 23 is rotatably connected to the upper end of the lower arm 22 by a second rotating shaft 231, the second rotating shaft 231 extends vertically, and the upper arm 23 can rotate in the horizontal direction around the second rotating shaft 231, so that the angle of the upper arm 23 relative to the lower arm 22 in the horizontal direction changes. Further adjusting the angle of the display screen 11 assembly in the horizontal direction.

In other embodiments, the second shaft 231 may be disposed in an inclined manner, so that the lower arm 22 can rotate around an inclined plane perpendicular to the axis of the second shaft 231.

It will be appreciated that in some embodiments, the first end of the upper arm 23 is pivotally connected to the upper end of the lower arm 22 via a second pivot 231, and the first end of the upper arm 23 is hinged to the second pivot 231. And the upper arm 23 can not only horizontally rotate around the second rotating shaft 231 to adjust the angle of the display screen 11 assembly. It is also possible to rotate up and down about the first end of the upper arm 23 to raise or lower the second end to adjust the height of the display screen 11 assembly.

In some embodiments, the upper arm 23 is a parallel four-bar linkage, and a gas spring 232 is disposed within the upper arm 23. The gas spring 232 is capable of extending or retracting to deform the parallel four bar linkage to automatically raise or lower the second end, i.e., the height of the display screen 11 assembly is automatically adjusted by the extension or retraction of the gas spring 232.

Still referring to fig. 1 and 2, a locking assembly is used to lock the screen housing 121 to the base 21, thereby securing the display screen 11. So that the ultrasonic diagnosis equipment can be transported, carried or pushed for a long distance, the display screen 11 is prevented from shaking, and the damage to the display screen 11 is avoided.

The locking assembly includes a first locking member 31 and a second locking member 32.

Referring to fig. 2, the first locking member 31 is disposed on the mounting base 122, and the first locking member 31 extends vertically. The lower arm 22 is provided with a locking hole 222, and when the upper arm 23 rotates to be folded with the lower arm 22, the first locking member 31 can be locked in the locking hole 222, so that the mounting seat 122 and the lower arm 22 are fixed.

Further, when the upper arm 23 is folded on the lower arm 22, the first locking member 31 does not interfere with the rotation of the upper arm 23.

Referring to fig. 4 in conjunction with fig. 1 and 2, in some embodiments, the first locking member 31 includes a lock shaft 311 rotatably mounted on the mounting seat 122 and a hook 3111 disposed on the lock shaft 311. The lock shaft 311 is mounted on the mount 122 through a damper shaft. Lock shaft 311 is rotationally damped relative to mount 122. When the first locking member 31 is not needed, the first locking member 31 only needs to be damped to rotate to one side, and the first locking member 31 can be kept at the position, so that the interference of the first locking member 31 on the adjustment movement of the upper support arm 23 and the display screen 11 can be avoided. Specifically, in the present embodiment, when it is not necessary to lock with the lower arm 22 using the first locking member 31, the first locking member 31 can damp the rotation to the horizontal direction and maintain the horizontal position so as to avoid interference with the lower arm 22.

In other embodiments, the second end of the upper arm 23 may further be provided with a locking groove 233, and when the locking shaft 311 rotates to the horizontal state, the hook 3111 can be locked with the locking groove 233 of the upper arm 23, so as to fix the first locking member 31 and the upper arm 23.

In some embodiments, the lock shaft 311 is provided with a first elastic member 3112, and the hook 3111 abuts against the first elastic member 3112, so that the hook 3111 is elastically clamped into the lock slot 233 or the lock hole 222. When the lock shaft 311 is not rotated to a proper position, the hook 3111 cannot be smoothly inserted into the lock groove 233 of the upper arm 23, and rigid collision with the upper arm 23 is avoided, so that the hook 3111 is prevented from being damaged. Similarly, when the lock shaft 311 is not rotated to a proper position, the hook 3111 cannot be smoothly locked into the lock hole 222 of the lower arm 22, and the hook 3111 is prevented from being rigidly collided with the lower arm 22 to be damaged.

In some embodiments, the lock shaft 311 further includes a pressing portion 3113 coupled to the hook 3111, so that the hook 3111 can be pushed out of the lock slot 233 or the lock hole 222 by pressing the pressing portion 3113.
