[0025] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] To simplify the drawings, only the parts relevant to the present invention are schematically shown in each figure. They do not represent the actual structure of the product. Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically depicted or labeled. As used herein, "one" not only means "only one" but also "more than one."

[0027] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0028] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.

[0029] In addition, in the description of the present invention, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0030] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific embodiments of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other embodiments can be obtained based on these drawings without inventive work.

[0031] See also Figures 1 to 2As shown, the utility model provides an ultrasonic diagnostic device, which includes a main unit 6, a roller 7 provided below the main unit 6, a battery assembly 300 fixed below the main unit 6, a keyboard assembly 4, a first display 1, a second display 3, a tray 5 and a printer 200. The ultrasonic diagnostic device also includes a first bracket 9 fixed to the keyboard assembly 4, a connecting arm 2 connecting the first display 1 and the first bracket 9 together, a second bracket 81 fixed to the main unit 6, and a lifting arm 82 connecting the keyboard assembly 4 and the second bracket 81. The lifting arm 82 and the second bracket 81 are connected together to form a lifting arm assembly 8. As needed, the user can adjust the height of the connecting arm 2 and the lifting arm 82 to flexibly adjust the height of the keyboard assembly 4 and the first display 1, thereby meeting the user's usage needs.

[0032] The connecting arm 2 is directly connected to the first display 1. The height of the first display 1 can be adjusted by rotating the connecting arm 2. Since the first display 1 is not very heavy, the load-bearing capacity of the connecting arm 2 does not need to be set too high. The lifting arm 82 is connected to the keyboard assembly 4. Adjusting the height of the lifting arm 82 can change the height of the keyboard assembly 4 and the first display 1. Since the lifting arm 82 needs to bear a large weight, the load-bearing capacity of the lifting arm 82 needs to be set relatively high.

[0033] When in use, the ultrasonic diagnostic equipment can be moved from one position to another by the roller 7. The height of the keyboard assembly 4 and the first display 1 can be changed by adjusting the inclination angle of the lifting arm 82. The height of the first display 1 can be changed by adjusting the inclination angle of the connecting arm 2. The coordinated use of the connecting arm 2 and the lifting arm 82 can flexibly adjust the height of the first display 1 and the keyboard assembly 4 to meet the use requirements of different heights. Preferably, gas springs are provided in both the connecting arm 2 and the lifting arm 82. Since the bearing capacity requirements of the connecting arm 2 and the lifting arm 82 are different, the gas spring in the connecting arm 2 can be a gas spring without a switch and a smaller volume, and the gas spring in the lifting arm 82 can be a gas spring without a switch and a larger volume.

[0034] See also Figures 3 to 6As shown, the lifting arm 82 includes a first mounting base 821 fixed to the keyboard assembly 4, a second mounting base 822 connected to the second bracket 81, a parallel beam mechanism 823 connecting the first mounting base 821 and the second mounting base 822, and a support member 8233 disposed within the parallel beam mechanism 822. The parallel beam mechanism 823 includes an upper parallel beam 8231 and a lower parallel beam 8232. During the lifting and lowering process of the lifting arm 82, the upper parallel beam 8231 and the lower parallel beam 8232 move parallel to each other to change the height of the first mounting base 821. Due to the configuration of the parallel beam mechanism 823, the first mounting base 821 moves parallel to the second mounting base 822 during the lifting and lowering process. The upper parallel beam 8231 includes a first base 82313, a first extension portion 82311 extending downward from one side of the first base 82313, and a second extension portion 82312 extending downward from the other side of the first base 82313. The lower parallel beam 8232 includes a second base 82323, a first protrusion 82321 extending upward from one side of the second base 82323, and a second protrusion 82322 extending upward from the other side of the second base 82323. The upper parallel beam 8231 and the lower parallel beam 8232 form a accommodating space for accommodating the support member 8233.

[0035] The upper parallel beam 8231 is provided with a first abutting surface 82314 and a second abutting surface 82315, which are connected to each other. Preferably, the first abutting surface 82314 is the inclined surface at the front end of the upper parallel beam 8231, and the second abutting surface 82315 is the lower end surface of the upper parallel beam 8231. In this embodiment, the upper parallel beam 8231 and the lower parallel beam 8232 are both integrally formed. In other embodiments, the upper parallel beam 8231 and the lower parallel beam 8232 may also be separate and fixed together through assembly.

[0036] The first mounting seat 821 is provided with a first receiving space 8212 and a first protrusion provided in the first receiving space 8212 , and the first protrusion is provided with a first stop surface 8211 .

[0037] The second mounting base 822 defines a second receiving space and includes a base 8223 and a first fixing member 8224 that secures the second end 82332 of the support member 8233 to the base 8223. The first fixing member 8224 is disposed within the second receiving space. To enhance the aesthetics of the second mounting base 822 and prevent foreign objects from entering the second receiving hole, the second mounting base 822 also includes a first housing 8221 and a second housing 8222 that are assembled together. In this embodiment, two speakers (not shown) are disposed on either side of the base 8223. The speakers are positioned within the space enclosed by the first housing 8221 and the second housing 8222.

[0038] The second mounting seat 822 is provided with a second protrusion located in the second receiving space, and a second stop surface 82231 is provided on the second protrusion. There are two second stop surfaces 82231, one located on each side of the second receiving space.

[0039] The support member 8233 includes a first end 82331 fixed to the upper parallel beam 8231 and a second end 82332 fixed to the second mounting base 822. The first end 82331 is rotatably connected to the first connecting member 82335, and the first connecting member 82335 is fixed to the upper parallel beam 8231 via the second fixing member 82334. The second end 82332 is rotatably connected to the first fixing member 8224, and the first fixing member 8224 is fixed to the base 8223. When the lifting arm 82 is raised or lowered, the support member 8233 can be extended and retracted to fix the lifting arm 82 at the desired height. Preferably, the support member 8233 is a gas spring with a switch. When the switch is turned on, the lifting arm 82 can be raised or lowered. When the lifting arm 82 reaches the desired height, the switch is turned off, and the lifting arm 82 can stay at the desired height.

[0040] Lifting arm 82 also includes a U-shaped wire holder 8235 positioned within the receiving space, with support member 8233 positioned within the opening of the U. Using wire holder 8235, wire harnesses passing through the receiving space are secured between wire holder 8235 and the sidewalls of parallel beam mechanism 823, preventing the harnesses from interfering with the movement of support member 8233.

[0041] The lifting arm 82 further includes a lower cover plate 8234 disposed below the lower parallel beam 8232 . The lower cover plate 8234 covers the lower parallel beam 8232 to prevent foreign objects from entering the inner side of the lifting arm 82 .

[0042] See also Figures 7 to 9 As shown, the upper parallel beam 8231 is connected to the first mounting seat 821 via a first rotating shaft 82361, the upper parallel beam 8231 is connected to the second mounting seat 822 via a third rotating shaft 82363, the lower parallel beam 8232 is connected to the first mounting seat 821 via a second rotating shaft 82362, and the lower parallel beam 8232 is connected to the second mounting seat 822 via a fourth rotating shaft 82364. The first rotating shaft 82361 and the second rotating shaft 82362 are located in the first receiving space, while the third rotating shaft 82363 and the fourth rotating shaft 82364 are located in the second receiving space. The line connecting the first rotating shaft 82361, the second rotating shaft 82362, the third rotating shaft 82363, and the fourth rotating shaft 82364 forms a parallelogram.

[0043] Figure 7The figure shows the lifting arm 82 when it is movable up and down. At this time, the first stop surface 8211 and the first abutting surface 82314 are in a non-contact state, and the second stop surface 82231 and the second abutting surface 82315 are in a non-contact state. The lifting arm 82 can be moved upward or downward. Figure 8 The figure shows a schematic diagram when the lifting arm 82 has reached the highest point. At this time, the first stop surface 8211 and the first abutting surface 82314 abut against each other to prevent the lifting arm 82 from rising further. The second stop surface 82231 and the second abutting surface 82315 are in a non-contact state, and the lifting arm 82 can choose to move downward. Figure 9 The diagram shows the lifting arm 82 at its lowest point. At this point, the second stop surface 82231 and the second abutting surface 82315 abut against each other, preventing the lifting arm 82 from further downward movement. The first stop surface 8211 and the first abutting surface 82314 are in a non-contact state, allowing the lifting arm 82 to move upward. The present invention achieves a full range of lift for the lifting arm 82 by providing a coordinated abutting surface with the stop surface, resulting in a simple structure and low manufacturing cost.
