DETAILED DESCRIPTION

[0041] Typical embodiments embodying the features and advantages of the present invention are described in detail in the following description. It should be understood that the present invention is capable of various variations in different embodiments without departing from the scope of the present invention, and that the descriptions and illustrations herein are intended to be illustrative rather than limiting.

[0042] In the description of this application, it should be understood that in the embodiments shown in the drawings, indications of directions or positional relationships (such as up, down, left, right, front, and back) are merely for the convenience of describing this application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions will also change accordingly.

[0043] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the described features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0044] See Figures 1 to 3 An embodiment of the present application provides a multi-position rotation locking module 100, which is mainly used for connecting functional components and supporting components in medical equipment. The multi-position rotation locking module 100 includes a base 10, a rotation component and a locking component 30.

[0045] Specifically, the base 10 is used to connect to the support component. The rotating assembly includes a rotating shaft 21 fixed to the base 10 and a connecting member 22 rotatably disposed on the rotating shaft 21. The rotation axis of the connecting member 22 is aligned with the axis of the rotating shaft 21, and the connecting member 22 is used to carry or connect functional components.

[0046] The locking assembly 30 includes a locking wheel 31, a movable member 32, and a fixed member 33. The locking wheel 31 is fixed to the base 10. A plurality of locking slots 311 are formed on the side of the locking wheel 31 and are spaced apart along the circumference of the locking wheel 31. The movable member 32 includes a connecting arm 321 and a movable wheel 322 disposed at one end of the connecting arm 321. The other end of the connecting arm 321 is movably connected to the fixed member 33, which is used to support or connect functional components.

[0047] The movable member 32 is rotatably mounted on the base 10. The rotation axis of the movable member 32, the axis of the movable wheel 322, and the axis of the locking wheel 31 are all colinear with the axis of the rotating shaft 21. A plurality of movable teeth 3221 are formed on the side of the movable wheel 322 and are spaced apart along the circumference of the movable wheel 322. The movable teeth 3221 are adapted to be engaged with the locking groove 311.

[0048] The movable member 32 can move relative to the base 10 and the fixed member 33 along the axis of the rotating shaft 21, so that the movable teeth 3221 can be disengaged from the locking groove 311. This allows the functional component connected to the fixed member 33 and the connecting member 22 to rotate relative to the support component connected to the base 10, thereby adjusting the angle between the functional component and the support component. When the movable member 32 moves along the axis of the rotating shaft 21, so that the movable teeth 3221 are adapted to engage with the locking groove 311, the functional component and the support component can be positioned at a fixed angle.

[0049] The multi-speed rotation locking module 100 of the present application can be flexibly used as an independent modular unit in various devices that need to be rotated and positioned at a set angle position. For example, the multi-speed rotation locking module 100 is used in medical equipment to realize the connection between the functional components and the supporting components, and to realize the relative rotation between the functional components and the supporting components, so that the functional components and the supporting components can be positioned at the set angle position.

[0050] Among them, the functional components can be the equipment itself, such as ultrasound diagnostic equipment, endoscope inspection equipment, electrocardiogram monitoring equipment, and artificial respirator, or the display screen, touch screen, operating console, control host and other components in the equipment, such as ultrasound diagnostic equipment, endoscope inspection equipment, electrocardiogram monitoring equipment, and artificial respirator. The supporting components can be the main body of the mobile vehicle, the equipment machine part, etc.

[0051] When the multi-position rotation locking module 100 of the present application connects functional components and supporting components, such as the display screen and the main body of the mobile vehicle in an ultrasonic diagnostic device, the display screen can be rotated relative to the main body of the mobile vehicle by rotating the rotating plate 221 and the fixing member 33 relative to the base 10. Therefore, medical personnel can adaptively adjust the angle range between the display screen and the main body of the mobile vehicle according to their own usage needs, making the ultrasonic diagnostic device more convenient for them to operate. In addition, by engaging the movable teeth 3221 on the movable wheel 322 with the locking groove 311 on the locking wheel 31, the display screen and the main body of the mobile vehicle can be positioned at a desired angle, and the display screen can be locked in a positioned hovering position. This can effectively prevent the display screen from rotating and deviating due to accidental touch or attenuation caused by repeated or long-term use, ensuring that it is always stably in the hovering position required by the medical personnel.

[0052] In addition, the multi-speed rotation locking module 100 of the present application can be flexibly used as an independent modular unit on various equipment that needs to be rotated and positioned at a set angle. It not only makes the assembly of related equipment products more flexible and quick, but also facilitates the maintenance and replacement of related components, effectively extending the overall service life of the equipment.

[0053] like Figure 1 and Figure 3 As shown, in some embodiments of the present application, the base 10 is overall C-shaped, and includes a bottom plate 11 and mounting plates connected to both ends of the bottom plate 11, and the two mounting plates are respectively a first mounting plate 12 and a second mounting plate 13.

[0054] The base plate 11 is used to connect to the support member. The first mounting plate 12 and the second mounting plate 13 provide a mounting position for the rotating assembly. The internal space enclosed by the first mounting plate 12, the second mounting plate 13 and the base plate 11 provides a mounting position for the locking assembly 30, thereby realizing an integrated arrangement of the rotating assembly and the locking assembly 30, which facilitates the modular design of the multi-speed rotating locking module 100.

[0055] In some examples, the base plate 11 is provided with mounting holes 111, and the support member is provided with assembly holes at positions corresponding to the mounting holes 111. The multi-position rotation locking module 100 may also include fasteners 40, which are inserted through the corresponding assembly holes and mounting holes 111 to securely connect the base 10 to the support member. The fasteners 40 may be screws, pins, etc. The mounting holes 111 and the assembly holes may be configured as corresponding screw holes, pin holes, etc.

[0056] In other examples, the base 10 and the support component can also be detachably connected through other structural forms, such as the snap-fitting of a card block and a card slot to achieve docking of the base 10 and the support component, interference fit between the base 10 and the support component, and magnetic adsorption connection between the base 10 and the support component.

[0057] In some embodiments of the present application, the first mounting plate 12 and the second mounting plate 13 are both vertically connected to the surface of the same side of the base plate 11. This arrangement not only facilitates the assembly of the rotating assembly and the locking assembly 30 on the base 10, but also facilitates the coaxial arrangement of the rotating shaft 21 in the rotating assembly and the movable wheel 322 in the locking assembly 30.

[0058] In other examples, according to the design of the rotation range of actual functional components and supporting components, the connection angle between the first mounting plate 12 and the second mounting plate 13 and the base plate 11 can also be set to other angles, such as 120°, 135°, etc.; and, in some examples, the base 10 can be other structural forms, such as retaining only one mounting plate, or the first mounting plate 12 and the second mounting plate 13 can be respectively connected to the opposite side surfaces of the base plate 11.

[0059] Further, combined with Figure 2 and Figure 3 As shown, in some embodiments of the present application, the rotating assembly is connected to the mounting plate of the base 10 , and the rotating assembly includes a rotating shaft 21 and a connecting member 22 rotatably disposed on the rotating shaft 21 .

[0060] In this embodiment, two sets of rotating assemblies are provided, each having the same structure, namely a first rotating assembly 201 and a second rotating assembly 202. The two sets of rotating assemblies can be connected to the base plate 11 via a mounting plate. Specifically, the first rotating assembly 201 is connected to the first mounting plate 12, and the second rotating assembly 202 is connected to the second mounting plate 13.

[0061] The connectors 22 in both sets of rotating components can be used to carry or connect functional components. The arrangement of the two sets of rotating components can effectively ensure the stability of the multi-position rotating locking module 100 in supporting or connecting the functional components, thereby ensuring the stability of the connection and relative rotation between the functional components and the supporting components.

[0062] In some examples, the rotating components can also be arranged into a structural form of three groups, four groups, etc. according to actual product requirements; and, in some examples of the rotating components, only one group can be set, and accordingly, the base 10 can only include one mounting plate for installing this group of rotating components.

[0063] The first rotating assembly 201 and the second rotating assembly 202 have the same structure. The structure of the rotating assembly will now be described using the first rotating assembly 201 as an example. The main difference between the first rotating assembly 201 and the second rotating assembly 202 is that the second rotating assembly 202 is connected to the second mounting plate 13. The detailed structure of the second rotating assembly 202 is described in the description of the first rotating assembly 201 and will not be repeated here.

[0064] Specifically, in some embodiments of the present application, the rotation shaft 21 of the first rotation assembly 201 is fixed to the first mounting plate 12. The rotation shaft 21 is perpendicular to the first mounting plate 12, and the axis direction of the rotation shaft 21 is consistent with the length direction of the base plate 11.

[0065] In some examples, the rotating shaft 21 includes a base portion 211 and a shaft portion 212 connected to the base portion 211. The diameter of the base portion 211 is larger than the diameter of the shaft portion 212. The shaft portion 212 is inserted through the first mounting plate 12. The base portion 211 is located inside the base 10, and the end of the shaft portion 212 away from the base portion 211 is arranged outside the first mounting plate 12. The outer peripheral surface of the shaft portion 212 includes a flat surface and a curved surface.

[0066] In this example, the first rotating assembly 201 may further include a locking nut 23. The end of the shaft portion 212 away from the base portion 211 is threaded. The locking nut 23 can be tightened on the end of the shaft portion 212 to achieve relative fixation of the rotating shaft 21 on the first mounting plate 12.

[0067] In some examples, the connector 22 may include a rotating plate 221 and an assembly plate 222 connected to one end of the rotating plate 221. The assembly plate 222 is bent and connected to the rotating plate 221. The end of the rotating plate 221 facing away from the assembly plate 222 is rotatably mounted on the rotating shaft 21. The assembly plate 222 is used to connect to or support the functional components. In this example, the assembly plate 222 can be removably connected to the functional components using a connection structure such as a screw or pin.

[0068] In some examples, the rotating plate 221 can be configured to be arc-shaped. This configuration allows the rotating plate 221 to rotate only slightly to achieve the desired rotation angle range of the functional component, thereby facilitating the modularization and miniaturization of the multi-position rotation locking module 100.

[0069] In some embodiments of the present application, the rotating plate 221 is disposed inside the first mounting plate 12. The first rotating assembly 201 further includes a friction washer 24, which is sleeved on the rotating shaft 21. The friction washer 24 is disposed between the first mounting plate 12 and the locknut 23, that is, between the rotating plate 221 and the locknut 23.

[0070] The friction washer 24 can be made of metal or non-metallic materials such as silicone or rubber. It provides a certain damping force for the rotating plate 221, preventing the functional components supported or connected by the connector 22 from rotating easily due to gravity or accidental collision when unlocked. Multiple friction washers 24 can be provided. Multiple friction washers 24 can be positioned on the outside of the first mounting plate 12, or some can be positioned on the outside and some on the inside of the first mounting plate 12.

[0071] In some examples, combined Figure 2 and Figure 3As shown, the rotating assembly may further include a limiting washer 25. The limiting washer 25 is sleeved on the rotating shaft 21 and arranged between the rotating plate 221 and the base portion 211 of the rotating shaft 21. A plurality of limiting washers 25 may be provided. The internal through hole of the limiting washer 25 is a special-shaped hole.

[0072] When the limiting washer 25 is mounted on the rotating shaft 21, its inner wall abuts the flat surface of the shaft portion 212, preventing the limiting washer 25 from rotating relative to the rotating shaft 21 along with the rotating plate 221. The limiting washer 25 is provided with a limiting opening 251, and the rotating plate 221 is provided with a limiting protrusion 2211. The combination of the limiting opening 251 and the limiting protrusion 2211 allows the rotational range of the rotating plate 221 to be set as needed, thereby limiting the rotational range of the functional components and preventing them from rotating to unnecessary positions during angle adjustment, which could hinder use or cause collisions.

[0073] In some examples, the rotating assembly may further include a locking washer 26, which is sleeved on the rotating shaft 21. A plurality of locking washers 26 may be provided, with some being provided between the friction washer 24 and the locking nut 23, and some being provided between the rotating plate 221 and the first mounting plate 12.

[0074] The internal through hole of the anti-loosening washer 26 is an irregular hole. When the anti-loosening washer 26 is sleeved on the rotating shaft 21, the inner wall of the anti-loosening washer 26 abuts against the flat surface of the shaft body 212, so that the anti-loosening washer 26 will not rotate relative to the rotating shaft 21 along with the rotating plate 221, so as to avoid transmitting the friction force when the rotating plate 221 rotates to the anti-loosening nut 23, thereby preventing the anti-loosening nut 23 from falling off.

[0075] The specific structure of the second rotating assembly 202 can be found in the above description of the first rotating assembly 201 and will not be repeated here.

[0076] Further, see Figures 1 to 3 In some embodiments of the present application, the locking assembly 30 is disposed in the inner space formed by the first mounting plate 12, the second mounting plate 13, and the bottom plate 11. The locking assembly 30 includes a locking wheel 31, a movable member 32, and a fixed member 33.

[0077] The locking assembly 30 may include a wheel seat 34, through which the locking wheel 31 is fixed to the base plate 11. The locking wheel 31 is connected to the wheel seat 34, and the locking wheel 31 and the wheel seat 34 may be an integrally formed structure.

[0078] In some examples, the wheel seat 34 can be detachably connected to the base plate 11 by a connection structure such as screws, pins, etc., or can be directly fixed to the base plate 11 by welding or the like.

[0079] The locking wheel 31 is fixed to the base plate 11 via a wheel seat 34. The axis of the locking wheel 31 is collinear with the axis of the rotating shaft 21. A plurality of locking teeth 312 are formed on one side of the locking wheel 31. The locking teeth 312 are evenly spaced along the circumference of the locking wheel 31, and a locking groove 311 is formed between adjacent locking teeth 312.

[0080] exist Figure 1 and Figure 2 In the viewing direction, the locking wheel 31 is arranged as a whole close to the first mounting plate 12, and the surface of the locking wheel 31 with the locking groove 311 is arranged toward the second rotating component 202, and the surface of the locking wheel 31 away from the locking groove 311 is arranged toward the first rotating component 201.

[0081] In this example, the locking wheel 31 has a wheel hole 313 along its axis. The end of the rotating shaft 21 of the first rotating assembly 201 is inserted and fixed in the wheel hole 313 to ensure that the axis of the rotating shaft 21 and the axis of the locking wheel 31 are collinear when the first rotating assembly 201 and the locking assembly 30 are assembled on the base 10.

[0082] In some embodiments of the present application, the movable member 32 is arranged on the side of the locking wheel 31 away from the first rotating assembly 201. The movable member 32 includes a connecting arm 321 and a movable wheel 322 arranged at one end of the connecting arm 321. The fixing member 33 is arranged at the end of the connecting arm 321 away from the movable wheel 322.

[0083] In some examples, the locking assembly 30 may further include a movable shaft 35 . The movable shaft 35 is fixed to the base 10 , and the axis of the movable shaft 35 is collinear with the axis of the rotating shaft 21 in the first rotating assembly 201 and the second rotating assembly 202 .

[0084] In this example, the locking assembly 30 may further include a connecting sleeve 361 and a connecting screw 362. The ends of the movable shaft 35 and the ends of the rotating shaft 21 of the second rotating assembly 202 are respectively inserted into the ends of the connecting sleeve 361. The movable shaft 35, the rotating shaft 21, and the connecting sleeve 361 are locked and fixed by the connecting screw 362, thereby fixing the movable shaft 35 on the base 10 and ensuring that the axis of the movable shaft 35 and the axis of the rotating shaft 21 are collinear.

[0085] In some examples, corresponding positions of the movable wheel 322 and the connecting arm 321 are provided with movable holes 3222, and the end of the movable member 32 is movably mounted on the movable shaft 35 through the movable hole 3222. The movable member 32 can rotate around the movable shaft 35 and can move linearly along the axis of the movable shaft 35.

[0086] In this example, the connecting arm 321 is configured in an arc shape. The curvature of the connecting arm 321 is similar to that of the rotating plate 221. This configuration allows the movable member 32 to rotate within the desired angle range of the functional component with only a small amount of rotation, thereby facilitating a modular and miniaturized design of the multi-position rotation locking module 100.

[0087] In some examples, the locking assembly 30 may further include a linear bearing 371 disposed in the movable hole 3222. Specifically, the movable member 32 is mounted on the movable shaft 35 via the linear bearing 371. The linear bearing 371 can be connected and secured to the movable member 32 via a bearing cover 372 and screws. The provision of the linear bearing 371 allows for smoother rotation and movement of the movable member 32 relative to the movable shaft 35.

[0088] Furthermore, the fixing member 33 includes a fixing plate 331 and a fixing shaft 332 fixedly connected to the fixing plate 331. The fixing plate 331 can be configured as a C-shaped structure, and the fixing plate 331 can be detachably connected to the functional component through a connecting structure such as screws or pins.

[0089] The fixed shaft 332 is fixedly connected to the fixed plate 331, and the axis of the fixed shaft 332 is aligned with the axis of the rotating shaft 21. A fixing hole 3211 is defined at the end of the connecting arm 321 facing away from the movable wheel 322. The connecting arm 321 is movably mounted on the fixed shaft 332 through the fixing hole 3211. The connecting arm 321 can rotate relative to the fixed shaft 332 and can move along the axis of the fixed shaft 332.

[0090] In some examples, a linear bearing 371 can be provided in the fixing hole 3211, and the linear bearing 371 can be connected and fixed to the movable member 32 through a bearing cover plate 372 and a screw. By providing the linear bearing 371, the rotation and movement of the movable member 32 relative to the fixed shaft 332 can be smoother.

[0091] Further, combined with Figure 2 、 Figure 3 as well as Figure 5 As shown, the movable wheel 322 is arranged on the side of the locking wheel 31 away from the first rotating assembly 201. The surface of the movable wheel 322 facing the locking wheel 31 is formed with a plurality of spaced movable teeth 3221, which are evenly spaced along the circumference of the locking wheel 31.

[0092] The movable teeth 3221 can be adapted to be snapped into the locking grooves 311, that is, the movable teeth 3221 can mesh with the locking teeth 312 of the locking wheel 31. When the movable teeth 3221 mesh with the locking teeth 312, the movable wheel 322 can be locked to the locking wheel 31, that is, the movable wheel 322 is fixed relative to the base 10 and cannot rotate or move relative to the base 10, thereby ensuring that the functional component is suspended at a set angle relative to the support component.

[0093] When the movable wheel 322 moves along the movable shaft 35 and the fixed shaft 332 toward the direction close to the second rotating component 202, the movable tooth 3221 can be disengaged from the engagement with the locking tooth 312. At this time, the movable wheel 322 is disengaged from the locking wheel 31, and the movable part 32 can rotate relative to the base 10, so that the functional component can rotate relative to the supporting component, so that the relative angle between the functional component and the supporting component is adjustable.

[0094] When the functional component is adjusted to the desired angular position relative to the supporting component, the movable part 32 can move along the movable axis 35 and the fixed axis 332 toward the direction close to the first rotating component 201, so that the movable teeth 3221 engage with the locking teeth 312, thereby causing the functional component to hover at the adjusted desired angular position relative to the supporting component.

[0095] In some embodiments of the present application, the movable part 32 has multiple locking positions. When the movable part 32 switches from one locking position to another adjacent locking position, the angle at which the movable part 32 rotates relative to the base 10 is consistent with the angle between the two adjacent locking teeth 312 in the circumferential direction.

[0096] In some examples, the locking position of the movable part 32 can be set by setting the number of locking teeth 312 and movable teeth 3221. For example, the number of locking teeth 312 and movable teeth 3221 can be set to 24 evenly spaced in the circumferential direction, that is, each 15° rotation of the movable part 32 is a locking position.

[0097] In other examples, different numbers of locking teeth 312 and movable teeth 3221 can be set according to different rotation angles of the required locking gears. For example, when the rotation angle of the movable part 32 relative to the base 10 for switching between two adjacent locking gears is 10°, the number of locking teeth 312 and movable teeth 3221 are both set to 36 evenly spaced in the circumferential direction; when the rotation angle of the movable part 32 relative to the base 10 for switching between two adjacent locking gears is 20°, the number of locking teeth 312 and movable teeth 3221 are both set to 18 evenly spaced in the circumferential direction; when the rotation angle of the movable part 32 relative to the base 10 for switching between two adjacent locking gears is 36°, the number of locking teeth 312 and movable teeth 3221 are both set to 10 evenly spaced in the circumferential direction.

[0098] In some examples, the multi-position rotation locking module 100 may further include a positioning member 50. The positioning member 50 is fixed to the rotating plate 221 of the first rotating assembly 201. The surface of the locking wheel 31 facing the first rotating assembly 201 is provided with a plurality of spaced-apart engaging grooves 314, and the ends of the positioning member 50 can be engaged and fixed in the engaging grooves 314.

[0099] When the connecting member 22 and the movable member 32 rotate relative to the base 10, the positioning member 50 can move relative to the locking wheel 31, so that the end of the positioning member 50 can be locked and fixed with any of the engaging grooves 314. In actual use, when the connecting member 22 and the movable member 32 rotate, the end of the positioning member 50 can move from one engaging groove 314 to another adjacent engaging groove 314. When the positioning member 50 moves into place, it makes a sound similar to "click", which reminds the user that the movable member 32 has moved to the new locking position.

[0100] In this example, there is a smooth transition between two adjacent engaging grooves 314, and the end surface of the positioning member 50 is an arc-shaped surface. This arrangement reduces the friction of the end of the positioning member 50 moving between the engaging grooves 314, making the positioning member 50 move more smoothly on the surface of the locking wheel 31.

[0101] like Figure 1 and Figure 2 As shown, in some embodiments of the present application, the locking assembly 30 may further include a movable spring 38. The movable spring 38 is mounted on the movable shaft 35 and is elastically retractable. One end of the movable spring 38 abuts against the surface of the connecting arm 321, and the other end abuts against the end surface of the connecting sleeve 361, thereby abutting against the base 10.

[0102] When the movable member 32 moves along the movable shaft 35 and the fixed shaft 332 toward the second rotating assembly 202 under the action of external force, the movable teeth 3221 can be disengaged from the locking teeth 312. At this time, the movable member 32 can press the movable spring 38 to compress it and generate elastic deformation.

[0103] After adjusting the relative angular positions of the functional component and the supporting component, the external force applied to the movable part 32 is released, and the movable spring 38 recovers its elastic deformation and abuts against the movable part 32 to move along the movable shaft 35 and the fixed shaft 332 toward the direction close to the first rotating component 201, thereby engaging the movable wheel 322 with the locking wheel 31.

[0104] Furthermore, if Figure 6 As shown, in some embodiments of the present application, the multi-speed rotation locking module may further include a cable 60 and a locking block 70 provided at one end of the cable 60 .

[0105] The end of the connecting arm 321 facing away from the movable wheel 322 is provided with a retaining groove 3212, and the locking block 70 is engaged with the retaining groove 3212 of the connecting arm 321 to be fixed to the connecting arm 321. The end of the cable 60 facing away from the locking block 70 is movably arranged. For example, the end of the cable 60 can be movably arranged on the operating table of the equipment. By pulling the end of the cable 60, the movable member 32 can be moved, thereby disengaging the movable wheel 322 from the locking wheel 31.

[0106] By providing the pull rope 60 and the locking block 70 , the movable part 32 can be moved relative to the base 10 outside the device without applying external force directly to the movable part 32 , making the overall operation of the multi-speed rotation locking module 100 more flexible and convenient.

[0107] In some other examples, an electromagnet may be provided on one side of the movable member 32 , and the movable member 32 may be moved closer to or farther from the locking wheel 31 by controlling the on and off of the electromagnet.

[0108] Specifically, when the electromagnet is energized, it can attract the movable member 32, causing the movable member 32 to move along the movable shaft 35 and the fixed shaft 332 toward the second rotating assembly 202, thereby disengaging the movable teeth 3221 from the meshing engagement with the locking teeth 312. When the electromagnet is de-energized, the movable member 32 is disengaged from the electromagnet, allowing the movable member 32 to move along the movable shaft 35 and the fixed shaft 332 toward the first rotating assembly 201, thereby engaging the movable wheel 322 with the locking wheel 31.

[0109] In addition, if Figure 7As shown, in some embodiments of the present application, the multi-position rotation locking module 100 may include a support base 80. The support base 80 is fixed to the base plate 11 and arranged between the first mounting plate 12 and the second mounting plate 13. The movable shaft 35 is connected to the support base 80 to be fixed to the base 10 through the support base 80.

[0110] In this embodiment, the connecting sleeve 361 and connecting screw 362 of the above embodiment are eliminated, and the end of the movable spring 38 abuts against the side wall of the support seat 80. The provision of the support seat 80 can improve the connection stability of the movable shaft 35 on the base 10, thereby ensuring the stability of the rotation and movement of the movable member 32 on the movable shaft 35.

[0111] In other embodiments, the connecting sleeve 361, connecting screw 362, and support base 80 can be eliminated, and the movable shaft 35 and the rotating shaft 21 of the second rotating assembly 202 can be directly configured as an integral shaft structure, that is, the movable member 32 and the rotating plate 221 of the second rotating assembly 202 are assembled using the same shaft. This arrangement can effectively improve the assembly accuracy of the locking assembly 30 and the rotating assembly, ensuring that the rotation axis of the movable member 32 and the rotation axis of the rotating plate 221 are collinear.

[0112] The multi-position rotation locking module 100 of the present application can be installed as an independent modular unit on various devices that require rotation and positioning at a set angle. For example, when used in medical devices, the multi-position rotation locking module 100 can connect functional components to support components and enable relative rotation between the functional components and the support components, allowing the functional components and the support components to be positioned at a set angle.

[0113] Specifically, in actual use, if it is necessary to adjust the relative angle between the functional component and the supporting component, the cable 60 can be pulled first to move the movable part 32 along the movable shaft 35 and the fixed shaft 332 toward the direction close to the second rotating component 202, so that the locking wheel 31 releases the lock on the movable wheel 322, so that the movable part 32 and the rotating plate 221 can rotate relative to the base 10; then the relative angle between the functional component and the supporting component is adjusted according to usage requirements, and the positioning part 50 makes a "click" sound when it moves into place, which can remind the user whether the movable part 32 has moved to the new locking position, and the user can judge whether it is adjusted into place based on this.

[0114] After being adjusted into place, due to the release of external force and the elastic action of the movable spring 38, the movable spring 38 can abut the movable part 32 and move along the movable shaft 35 and the fixed shaft 332 toward the direction close to the first rotating component 201, so that the movable wheel 322 engages with the locking wheel 31 to position the functional component to hover at the desired angular position.

[0115] See Figure 8 One embodiment of the present application further provides a mobile trolley 1000. The mobile trolley 1000 includes a vehicle body 200, a moving wheel 300 disposed at the bottom of the vehicle body 200, and a multi-position rotation locking module 100. The specific structure of the multi-position rotation locking module 100 has been described above and will not be repeated here.

[0116] The rotation of the moving wheels 300 enables the mobile trolley 1000 to move on the ground, making the mobile trolley 1000 more flexible to use. The vehicle body 200 is the main part of the mobile trolley 1000, and the moving wheels 300 are located at the bottom of the vehicle body 200. The multi-speed rotation locking module 100 is located on the top of the vehicle body 200, and the base 10 is used to connect to the top of the vehicle body 200.

[0117] Functional components such as an operating console, control panel, display screen, and touch screen can be directly connected to the connector 22 and the fixing member 33. By rotating the fixing member 33 and the connector 22 relative to the base 10, the functional components can be rotated relative to the vehicle body 200 and can hover at a set angle, so that the functional components can be adjusted to a suitable angle relative to the vehicle body 200, thereby facilitating user operation.

[0118] In some examples, the mobile trolley 1000 may further include a support platform 400, which may be configured to have a different profile, such as a rectangular, circular, elliptical, polygonal, etc. The bottom surface of the support platform 400 is connected and fixed to the fixing member 33 and the connecting member 22, and the top surface of the support platform 400 is used to support functional equipment, such as an operating console, a control panel, a display screen, a touch screen, etc.

[0119] That is, in this example, the fixing member 33 and the connecting member 22 support functional devices such as an operating console, control panel, display screen, touch screen, etc. through the support platform 400. By providing the support platform 400, there is no need to connect functional components to the fixing member 33 and the connecting member 22. The support platform 400 can flexibly support various functional devices, making the mobile dolly 1000 more applicable.

[0120] Further, see Figure 9 and Figure 10One embodiment of the present application further provides a mobile medical device 10000, which includes a portable ultrasound device 2000 and a mobile trolley 1000. The structure of the mobile trolley 1000 has been described above and will not be repeated here.

[0121] The portable ultrasound device 2000 is set on the support table 400. The portable ultrasound device 2000 may include a main unit 2001 and a screen 2002. The screen 2002 is rotatably connected to the main unit 2001. The screen 2002 rotates relative to the main unit 2001, enabling the portable ultrasound device 2000 to be adjusted to a notebook mode ( Figure 8 shown) and tablet mode ( Figure 9 shown).

[0122] Under the action of the multi-position rotation locking module 100, the support platform 400 can rotate the vehicle body 200 and can hover at a set angle position, so that the portable ultrasound device 2000 can be adjusted to a suitable angle position relative to the vehicle body 200, thereby facilitating user operation.

[0123] During specific use, when the angle of the support platform 400 to the horizontal plane is adjusted to 10° to 45°, the portable ultrasound device 2000 can be adjusted to the notebook mode; when the angle of the support platform 400 to the horizontal plane is adjusted to 45° to 55°, the portable ultrasound device 2000 can be adjusted to the tablet mode, so that the mobile medical device 10000 can flexibly meet the various applicable needs of medical staff.

[0124] For the multi-speed rotation locking module, mobile trolley and mobile medical equipment of the present application, the multi-speed rotation locking module can be flexibly used as an independent modular unit on various equipment that need to rotate and need to be positioned at a set angle position. For example, when the multi-speed rotation locking module is used in medical equipment, it can realize the connection between the functional components and the supporting components, and can realize the relative rotation between the functional components and the supporting components, so that the functional components and the supporting components can be positioned at the set angle position, so that the corresponding functional components are locked in the positioned hovering position, effectively avoiding the rotation offset of the functional components due to accidental touch or attenuation due to multiple and long-term use, ensuring that it is always stably in the hovering position state required by the user, and convenient for users to use it efficiently and flexibly.

Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope of the appended claims. All changes and modifications that fall within the scope of the claims or their equivalents are intended to be covered by the appended claims.
