Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a multi-position rotation locking module, a mobile trolley, and a mobile medical device. Background Technology

[0002] With the continuous advancement of medical science and technology, more and more medical equipment is being applied to modern medicine. Medical equipment has become an important field of modern medicine, and the current development of medicine largely depends on the development of instruments and equipment.

[0003] Medical equipment can include diagnostic equipment such as ultrasound diagnostic equipment, endoscopy equipment, electrocardiogram monitoring equipment, and nuclear medicine equipment; therapeutic equipment such as gastric lavage machines, laser generators, dialysis equipment, and ventilators; and auxiliary equipment such as sterilization equipment, refrigeration equipment, oxygen supply systems, and blood bank equipment.

[0004] Some medical devices, such as ultrasound diagnostic equipment, endoscopy equipment, electrocardiogram monitoring equipment, and ventilators, typically have components such as displays, touch screens, and operating consoles. When using these devices, medical staff need to adjust the relative angles of the displays, touch screens, and operating consoles according to their operating habits, standing or sitting positions, and relative distance from the patient.

[0005] Currently, although these medical devices have angle adjustment functions, after the angle is adjusted, the display screen, touch screen, operating table and other components are in a hovering state. If accidentally touched, the angle can easily deviate, affecting the normal use by medical staff. Furthermore, after repeated angle adjustments, the hovering function of the rotating shaft will weaken or even fail, affecting the overall lifespan of the medical device. Summary of the Invention

[0006] The purpose of this invention is to solve the technical problem in the prior art that after the angle of medical equipment is adjusted, the display screen, touch screen, operating table and other components are in a hovering state. Accidental touch can easily cause the angle to deviate, and repeated angle adjustments can cause the hovering function to fail, which affects the normal use by medical staff and shortens the service life of medical equipment.

[0007] To address the aforementioned technical problems, this invention provides a multi-position rotation locking module, which is used for connecting functional components and support components in medical devices. The multi-position rotation locking module includes:

[0008] The base is used to connect to the supporting component;

[0009] A rotating assembly includes a rotating shaft fixed on the base and a connector rotatably mounted on the rotating shaft; the axis of rotation of the connector is aligned with the axis of rotation of the rotating shaft, and the connector is used to support or connect the functional component.

[0010] The locking assembly includes a locking wheel, a movable component, and a fixing component; the locking wheel is fixed to the base, and a plurality of locking grooves are formed on the side of the locking wheel and evenly spaced along the circumference of the locking wheel; the movable component includes a connecting arm and a movable wheel disposed at one end of the connecting arm, the other end of the connecting arm is movably connected to the fixing component, and the fixing component is used to support or connect the functional component;

[0011] The movable component is rotatably mounted on the base, and the rotation axis of the movable component, the axis of the movable wheel, and the axis of the locking wheel are all collinear with the axis of the rotation axis. The side of the movable wheel has a plurality of movable teeth evenly spaced along the circumference of the movable wheel, and the movable teeth can be fitted into the locking groove.

[0012] The movable component can move relative to the base and the fixed component along the axial direction of the rotation axis, so that the movable tooth can disengage from the locking groove, and the functional component connected to the fixed component and the connecting component can rotate relative to the support component connected to the base, so that the angle between the functional component and the support component is adjustable; when the movable component moves along the axial direction of the rotation axis and the movable tooth is adapted to engage in the locking groove, the functional component and the support component can be positioned at a fixed included angle position.

[0013] In some embodiments of this application, the locking assembly further includes a movable shaft, which is fixed on the base, and the axis of the movable shaft is collinear with the axis of the rotating shaft.

[0014] The movable wheel and the connecting arm are provided with movable holes at corresponding positions, and the movable component is rotatably mounted on the movable shaft through the movable holes; the movable component can move along the axial direction of the movable shaft.

[0015] In some embodiments of this application, the locking assembly further includes a movable spring, which is sleeved on the movable shaft and is elastically expandable and contractible. One end of the movable spring abuts against the movable member, and the other end abuts against the base. The movable member moves along the axial direction of the movable shaft to disengage the movable tooth from the locking groove, and the movable spring is compressible to produce elastic deformation. When the movable spring returns to its elastic deformation, it abuts against the movement of the movable member to engage the movable tooth in the locking groove.

[0016] In some embodiments of this application, the fixing member includes a fixing plate and a fixing shaft fixedly connected to the fixing plate. The fixing plate is used to connect and fix with the functional component, and the axial direction of the fixing shaft is consistent with the axial direction of the rotating shaft.

[0017] The end of the connecting arm is rotatably sleeved on the fixed shaft, and the connecting arm is movable along the axial direction of the fixed shaft.

[0018] In some embodiments of this application, the multi-position rotation locking module further includes a cable and a locking block disposed at one end of the cable, the locking block being engaged with the connecting arm; pulling the end of the cable away from the locking block causes the movable member to move along the axial direction of the rotation shaft, thereby enabling the movable tooth to disengage from the locking groove.

[0019] In some embodiments of this application, the side of the locking wheel is formed with a plurality of locking teeth evenly spaced along the circumference of the locking wheel, the interval between two adjacent locking teeth forms the locking groove, and the locking teeth can mesh with the movable teeth;

[0020] The movable component has multiple locking positions. When the movable component switches from one locking position to another adjacent locking position, the angle at which the movable component rotates relative to the base is the same as the angle between the two adjacent locking teeth in the circumferential direction.

[0021] In some embodiments of this application, the connector includes a rotating plate and an assembly plate connected to one end of the rotating plate. The assembly plate is used to connect to or support the functional component. The end of the rotating plate opposite to the assembly plate is rotatably sleeved on the rotating shaft. One end of the rotating shaft is fixed to the base, and the other end of the rotating shaft is fixed to the locking wheel.

[0022] In some embodiments of this application, the multi-position rotation locking module further includes a positioning member, which passes through the rotating plate and is arranged on one side of the locking wheel; the side of the locking wheel opposite to the locking groove is provided with a plurality of spaced-apart snap-fit ​​grooves, and the end of the positioning member can be snapped and fixed in the snap-fit ​​grooves.

[0023] When the connector rotates around the rotating shaft, the positioning member can move relative to the locking wheel so that the end of the positioning member can be engaged and fixed with any of the locking slots.

[0024] In some embodiments of this application, the rotating assembly is provided in two sets, and the two sets of rotating assemblies are respectively disposed on both sides of the locking assembly.

[0025] This application also provides a mobile trolley, which includes a vehicle body, mobile wheels disposed at the bottom of the vehicle body, and the aforementioned multi-position rotation locking module, wherein the base of the multi-position rotation locking module is fixed to the top of the vehicle body.

[0026] The connector and fixing member of the multi-position rotation locking module are used to support or connect the functional component. The fixing member and the connector rotate relative to the base, so that the functional component can rotate relative to the vehicle body.

[0027] In some embodiments of this application, the mobile trolley further includes a support platform connected to the fixing member and the connecting member, and the surface of the support platform is used to support the functional components.

[0028] This application also provides a mobile medical device, which includes a portable ultrasound device and the aforementioned mobile trolley, wherein the portable ultrasound device is mounted on the support platform.

[0029] As can be seen from the above technical solution, the beneficial effects of the present invention are as follows: In the multi-position rotation locking module, mobile trolley, and mobile medical device of the present invention, the multi-position rotation locking module can be flexibly applied as an independent module unit to various devices that need to rotate and be positioned at a set angle. For example, when the multi-position rotation locking module is applied to a medical device, it can realize the connection between the functional component and the support component, and can realize the relative rotation between the functional component and the support component, so that the functional component and the support component can be positioned at a set angle, thereby locking the corresponding functional component at the positioning and hovering position, effectively avoiding the situation where the functional component rotates and shifts due to accidental touch or attenuation caused by repeated or long-term use, ensuring that it is always stably in the hovering position state required by the user, making it convenient for users to use efficiently and flexibly.

Detailed Implementation

[0041] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various variations in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations herein are for illustrative purposes only and not intended to limit the present invention.

[0042] In the description of this application, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction 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 device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications 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 technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0044] See Figures 1 to 3 One embodiment of this application provides a multi-position rotation locking module 100, which is mainly used for the connection between functional components and support components in medical devices. 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 with the support component. The rotating assembly includes a rotating shaft 21 fixed to the base 10 and a connector 22 rotatably mounted on the rotating shaft 21. The axis of rotation of the connector 22 is aligned with the axis of rotation of the rotating shaft 21, and the connector 22 is used to support or connect functional components.

[0046] The locking assembly 30 includes a locking wheel 31, a movable member 32, and a fixing member 33. The locking wheel 31 is fixed to the base 10, and a plurality of locking grooves 311 are formed on the side of the locking wheel 31 at intervals 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 fixing member 33, which is used to support or connect functional components.

[0047] The movable component 32 is rotatably mounted on the base 10. The rotation axis of the movable component 32, the axis of the movable wheel 322, and the axis of the locking wheel 31 are all collinear with the axis of the rotation shaft 21. The side of the movable wheel 322 has a plurality of movable teeth 3221 arranged at intervals along the circumference of the movable wheel 322. The movable teeth 3221 can be fitted and engaged in the locking groove 311.

[0048] The movable member 32 can move relative to the base 10 and the fixed member 33 along the axial direction of the rotation shaft 21, so that the movable tooth 3221 can disengage from the locking groove 311, allowing the functional component connected to the fixed member 33 and the connecting member 22 to rotate relative to the support member connected to the base 10, thereby making the angle between the functional component and the support member adjustable. When the movable member 32 moves along the axial direction of the rotation shaft 21 and the movable tooth 3221 is fitted into the locking groove 311, the functional component and the support member can be positioned at a fixed included angle.

[0049] The multi-position rotation locking module 100 of this application can be flexibly applied as an independent module unit to various devices that need to rotate and be positioned at a set angle. For example, when the multi-position rotation locking module 100 is applied to medical devices, it can realize the connection between functional components and support components, and realize the relative rotation between functional components and support components, so that functional components and support components can be positioned at a set angle.

[0050] The functional components can be the equipment itself, such as ultrasound diagnostic equipment, endoscopy equipment, electrocardiogram monitoring equipment, or ventilator, or components such as display screens, touch screens, operating consoles, and control hosts in the equipment. The supporting components can be the main body of the mobile vehicle or the equipment platform.

[0051] When the multi-position rotation locking module 100 of this application connects functional components and support components, such as connecting the display screen and the main body of the mobile cart in an ultrasound diagnostic device, the rotation of the rotating plate 221 and the fixing member 33 relative to the base 10 can realize the rotation of the display screen relative to the main body of the mobile cart. Therefore, medical personnel can adaptively adjust the angle range between the display screen and the main body of the mobile cart according to their own usage needs, making the ultrasound diagnostic device more convenient for their operation and use. Furthermore, 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 cart can be positioned at the required angle, locking the display screen at the positioning and hovering position. This effectively avoids the display screen from rotating and shifting due to accidental touch or attenuation caused by repeated or prolonged use, ensuring that it is always stably in the hovering position required by the medical personnel.

[0052] Furthermore, the multi-position rotation locking module 100 of this application can be flexibly applied as an independent module unit to various devices that need to rotate and be positioned at a set angle, which 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 this application, the base 10 is C-shaped in general, and includes a base plate 11 and mounting plates connected to both ends of the base plate 11, the two mounting plates being a first mounting plate 12 and a second mounting plate 13, respectively.

[0054] The base plate 11 is used to connect with the support component. The first mounting plate 12 and the second mounting plate 13 are used to provide mounting positions for the rotating component. The internal space formed by the first mounting plate 12, the second mounting plate 13 and the base plate 11 is used to provide mounting positions for the locking component 30, thereby realizing the integrated setting of the rotating component and the locking component 30, which is conducive to realizing the modular design of the multi-position rotating locking module 100.

[0055] In some examples, the base plate 11 has mounting holes 111, and the support component has assembly holes at the corresponding positions of the mounting holes 111. The multi-position rotation locking module 100 may also include fasteners 40, which pass through the corresponding assembly holes and mounting holes 111, thereby connecting and fixing the base 10 to the support component. The fasteners 40 can be screws, pins, etc. The mounting holes 111 and assembly holes can be correspondingly configured as 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-fit ​​of the card block and the card slot to achieve docking between the base 10 and the support component, the interference fit between the base 10 and the support component, and the magnetic adsorption connection between the base 10 and the support component.

[0057] In some embodiments of this application, the first mounting plate 12 and the second mounting plate 13 are both vertically connected to the same surface 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, depending on the design of the rotation range of the actual functional components and support components, the connection angle between the first mounting plate 12 and the second mounting plate 13 and the base plate 11 can be set to other angles, such as 120°, 135°, etc.; and in some examples, the base 10 can be in other structural forms, such as retaining only one mounting plate, or the first mounting plate 12 and the second mounting plate 13 can be connected to the opposite side surfaces of the base plate 11 respectively.

[0059] Furthermore, combined Figure 2 and Figure 3 As shown, in some embodiments of this application, the rotating assembly is connected to the mounting plate of the base 10. The rotating assembly includes a rotating shaft 21 and a connector 22 rotatably disposed on the rotating shaft 21.

[0060] In this embodiment, there are two sets of rotating components, both with identical structures. The two sets of rotating components are a first rotating component 201 and a second rotating component 202. The two sets of rotating components can be connected to the base plate 11 via a mounting plate. Specifically, the first rotating component 201 is connected to the first mounting plate 12, and the second rotating component 202 is connected to the second mounting plate 13.

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

[0062] In some examples, the rotating components can also be configured into three, four or more groups according to actual product requirements; and in some examples of rotating components, only one group can be set, and correspondingly, the base 10 can include only one mounting plate for mounting the 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 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. For the specific structure of the second rotating assembly 202, please refer to the description of the first rotating assembly 201, which will not be repeated below.

[0064] Specifically, in some embodiments of this application, the rotation shaft 21 of the first rotating assembly 201 is fixedly mounted on the first mounting plate 12. The rotation shaft 21 is perpendicular to the first mounting plate 12, and the axial 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 passes through the first mounting plate 12. The base portion 211 is located inside the base 10, and one end of the shaft portion 212 away from the base portion 211 is arranged on the outer side of 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 also include a lock nut 23, and the end of the shaft portion 212 away from the base portion 211 is threaded. The lock nut 23 can be tightened onto 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, 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 to connect with the rotating plate 221, and 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 functional components. In this example, the assembly plate 222 may be detachably connected to the functional components via a connection structure such as screws or pins.

[0068] In some examples, the rotating plate 221 can be configured as an arc. This configuration allows the rotating plate 221 to rotate only a small amount to reach the rotation angle range of the functional component, which is beneficial for the modular and miniaturized design of the multi-position rotation locking module 100.

[0069] In some embodiments of this application, the rotating plate 221 is arranged inside the first mounting plate 12. The first rotating assembly 201 also includes a friction washer 24, which is sleeved on the rotating shaft 21. The friction washer 24 is arranged between the first mounting plate 12 and the anti-loosening nut 23, that is, between the rotating plate 221 and the anti-loosening nut 23.

[0070] The friction washer 24 can be made of metal or non-metallic materials, such as silicone or rubber. The friction washer 24 provides a certain damping force to the rotating plate 221, preventing the functional components of the connector 22 from easily rotating due to gravity or accidental contact when unlocked. Multiple friction washers 24 can be provided. These multiple friction washers 24 can be all located on the outer side of the first mounting plate 12, or they can be partially located on the outer side and partially on the inner side of the first mounting plate 12.

[0071] In some examples, combined Figure 2 and Figure 3As shown, the rotating assembly may also 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. Multiple limiting washers 25 may be provided. The internal through hole of the limiting washer 25 is an irregularly shaped hole.

[0072] When the limiting washer 25 is fitted onto the rotating shaft 21, the inner wall of the limiting washer 25 abuts against the flat surface of the shaft body 212, preventing the limiting washer 25 from rotating relative to the rotating shaft 21 along with the rotating plate 221. The limiting washer 25 has a limiting opening 251, and the rotating plate 221 has a limiting protrusion 2211. Through the cooperation of the limiting opening 251 and the limiting protrusion 2211, the rotatable range of the rotating plate 221 can be set as needed, thereby limiting the rotatable range of the functional component and preventing it from rotating to an unnecessary position when adjusting the angle, thus avoiding obstruction of use or collision.

[0073] In some examples, the rotating assembly may also include a locking washer 26, which is fitted onto the rotating shaft 21. Multiple locking washers 26 may be provided, some positioned between the friction washer 24 and the locking nut 23, and some positioned between the rotating plate 221 and the first mounting plate 12.

[0074] The internal through hole of the anti-loosening washer 26 is an irregularly shaped hole. When the anti-loosening washer 26 is fitted 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 with the rotating plate 221, so as to avoid transmitting the friction force of the rotating plate 221 to the anti-loosening nut 23, thereby preventing the anti-loosening nut 23 from falling off.

[0075] The specific structure of the second rotating component 202 is described above in the description of the first rotating component 201, and will not be repeated here.

[0076] Further, see Figures 1 to 3 In some embodiments of this application, the locking component 30 is disposed in the internal space formed by the first mounting plate 12, the second mounting plate 13, and the base plate 11. The locking component 30 includes a locking wheel 31, a movable part 32, and a fixing part 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 integrally formed.

[0078] In some examples, the wheel seat 34 can be detachably connected to the base plate 11 by means of a connecting structure such as screws or pins, or it can be directly fixed to the base plate 11 by means of welding or other methods.

[0079] The locking wheel 31 is fixed to the base plate 11 by the wheel seat 34, and 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, and the plurality of locking teeth 312 are evenly spaced along the circumference of the locking wheel 31, and a locking groove 311 is formed between two adjacent locking teeth 312.

[0080] exist Figure 1 and Figure 2 In the view direction, the locking wheel 31 is positioned close to the first mounting plate 12, and the surface of the locking wheel 31 with the locking groove 311 faces the second rotating component 202, while the surface of the locking wheel 31 facing away from the locking groove 311 faces the first rotating component 201.

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

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

[0083] In some examples, the locking assembly 30 may also include a movable shaft 35. The movable shaft 35 is fixed to the base 10, and its axis 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 end of the movable shaft 35 and the end of the rotating shaft 21 of the second rotating assembly 202 are respectively inserted through the two ends of the connecting sleeve 361, and the movable shaft 35, the rotating shaft 21 and the connecting sleeve 361 are locked and fixed by the connecting screw 362, so as to fix the movable shaft 35 on the base 10 and to ensure that the axis of the movable shaft 35 and the axis of the rotating shaft 21 are collinear.

[0085] In some examples, a movable hole 3222 is provided at the corresponding position of the movable wheel 322 and the connecting arm 321, and the end of the movable member 32 is movably sleeved on the movable shaft 35 through the movable hole 3222. The movable member 32 can rotate about the movable shaft 35 and can move linearly along the axial direction of the movable shaft 35.

[0086] In this example, the connecting arm 321 is arc-shaped. The curvature of the connecting arm 321 is similar to that of the rotating plate 221. This arrangement allows the movable part 32 to rotate only a small amount to reach the rotation angle range of the functional component, which is beneficial for realizing the modular and miniaturized design of the multi-position rotation locking module 100.

[0087] In some examples, the locking assembly 30 may also include a linear bearing 371 disposed in the movable hole 3222, i.e., the movable element 32 is fitted onto the movable shaft 35 via the linear bearing 371. The linear bearing 371 can be connected and fixed to the movable element 32 by a bearing cover plate 372 and screws. By providing the linear bearing 371, the rotation and movement of the movable element 32 relative to the movable shaft 35 can be made smoother.

[0088] Furthermore, the fastener 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 connection structure such as screws or pins.

[0089] A fixed shaft 332 is fixedly connected to a fixed plate 331, and the axial direction of the fixed shaft 332 is consistent with the axial direction of the rotating shaft 21. A connecting arm 321 has a fixing hole 3211 at its end opposite to the movable wheel 322, and the connecting arm 321 is movably sleeved 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 axial direction of the fixed shaft 332.

[0090] In some examples, a linear bearing 371 can be installed in the fixed hole 3211. The linear bearing 371 can be connected and fixed to the moving part 32 by a bearing cover plate 372 and screws. By installing the linear bearing 371, the rotation and movement of the moving part 32 relative to the fixed shaft 332 can be made smoother.

[0091] Furthermore, combined 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 opposite to the first rotating assembly 201. The surface of the movable wheel 322 facing the locking wheel 31 has a plurality of spaced movable teeth 3221, which are evenly spaced along the circumference of the locking wheel 31.

[0092] The movable tooth 3221 can be fitted into the locking groove 311, that is, the movable tooth 3221 can mesh with the locking tooth 312 of the locking wheel 31. When the movable tooth 3221 meshes with the locking tooth 312, the movable wheel 322 can be locked on the locking wheel 31, that is, the movable wheel 322 is fixed relative to the base 10, and the movable wheel 322 cannot rotate or move relative to the base 10, so as to ensure that the functional component is suspended at a set included angle position relative to the supporting component.

[0093] When the movable wheel 322 moves along the movable shaft 35 and the fixed shaft 332 toward the direction of approaching the second rotating component 202, the movable tooth 3221 can disengage from the locking tooth 312. At this time, the movable wheel 322 is released from the lock of 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 support component, making the relative angle between the functional component and the support component adjustable.

[0094] Once the functional component is adjusted to the desired angle position relative to the support component, the movable component 32 can 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 tooth 3221 engages with the locking tooth 312, thereby suspending the functional component relative to the support component at the adjusted desired angle position.

[0095] In some embodiments of this application, the movable member 32 has multiple locking positions. When the movable member 32 switches from one locking position to another adjacent locking position, the angle of rotation of the movable member 32 relative to the base 10 is the same as 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 both be set to 24 evenly spaced in the circumferential direction, that is, the movable part 32 rotates 15° for one 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 positions. For example, when the rotation angle of the movable part 32 relative to the base 10 between two adjacent locking positions is 10°, the number of locking teeth 312 and movable teeth 3221 is set to 36 evenly spaced in the circumferential direction; when the rotation angle of the movable part 32 relative to the base 10 between two adjacent locking positions is 20°, the number of locking teeth 312 and movable teeth 3221 is set to 18 evenly spaced in the circumferential direction; when the rotation angle of the movable part 32 relative to the base 10 between two adjacent locking positions is 36°, the number of locking teeth 312 and movable teeth 3221 is set to 10 evenly spaced in the circumferential direction.

[0098] In some examples, the multi-position rotation locking module 100 may also include a positioning member 50. The positioning member 50 is fixedly mounted on the rotating plate 221 of the first rotating assembly 201, and the locking wheel 31 has a plurality of spaced-apart locking grooves 314 on its surface facing the first rotating assembly 201. The end of the positioning member 50 can be locked in the locking grooves 314.

[0099] When the connector 22 and the movable part 32 rotate relative to the base 10, the positioning part 50 can move relative to the locking wheel 31, so that the end of the positioning part 50 can be engaged and fixed with any of the locking slots 314. In actual use, when the connector 22 and the movable part 32 rotate, the end of the positioning part 50 can move from one locking slot 314 to another adjacent locking slot 314. When the positioning part 50 moves into place, it makes a sound similar to "click" to remind the user that the movable part 32 has moved to a new locking position.

[0100] In this example, there is a smooth transition between two adjacent snap-fit ​​slots 314, and the end face of the positioning member 50 is an arc-shaped surface. This arrangement reduces the frictional force on the end of the positioning member 50 as it moves between the snap-fit ​​slots 314, making the movement of the positioning member 50 on the surface of the locking wheel 31 smoother.

[0101] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the locking assembly 30 may further include a movable spring 38. The movable spring 38 is sleeved on the movable shaft 35 and is capable of elastic extension and retraction. One end of the movable spring 38 abuts against the surface of the connecting arm 321, and the other end abuts against the base 10 by abutting against the end face of the connecting sleeve 361.

[0102] When the movable part 32 moves toward the direction of the second rotating assembly 202 along the movable shaft 35 and the fixed shaft 332 under the action of external force, the movable tooth 3221 can disengage from the locking tooth 312. At this time, the movable part 32 can press against the movable spring 38 to compress it and produce elastic deformation.

[0103] After adjusting the relative angular positions of the functional components and the support components, the external force applied to the movable component 32 is released, and the movable spring 38 restores its elastic deformation and abuts against the movable component 32, moving along the movable shaft 35 and the fixed shaft 332 toward the direction closer to the first rotating assembly 201, thereby causing the movable wheel 322 to engage with the locking wheel 31.

[0104] Furthermore, such as Figure 6 As shown, in some embodiments of this application, the multi-position rotation locking module may further include a cable 60 and a locking block 70 disposed at one end of the cable 60.

[0105] The connecting arm 321 has a retaining groove 3212 at one end opposite to the movable wheel 322. The locking block 70 engages with the retaining groove 3212 of the connecting arm 321 to secure it to the connecting arm 321. The end of the cable 60 opposite to the locking block 70 is movably disposed. For example, the end of the cable 60 can be movably disposed on the operating table of the equipment. By pulling the end of the cable 60, the movable part 32 can be moved, thereby disengaging the movable wheel 322 from the locking wheel 31.

[0106] By setting the cable 60 and the locking block 70, the movement of the movable part 32 relative to the base 10 can be achieved from outside the device, without having to apply external force directly to the movable part 32, making the multi-position rotation locking module 100 more flexible and convenient to operate.

[0107] In other examples, an electromagnet can also be used. This electromagnet is arranged on one side of the movable member 32, and the movable member 32 can be moved closer to or further away from the locking wheel 31 by controlling the on and off of the electromagnet.

[0108] Specifically, when the electromagnet is energized, it attracts the movable part 32, causing the movable part 32 to move along the movable shaft 35 and the fixed shaft 332 toward the direction closer to the second rotating assembly 202, thereby disengaging the movable tooth 3221 from its engagement with the locking tooth 312. When the electromagnet is de-energized, the movable part 32 disengages from the electromagnet, allowing it to move along the movable shaft 35 and the fixed shaft 332 toward the direction closer to the first rotating assembly 201, thereby engaging the movable wheel 322 with the locking wheel 31.

[0109] In addition, such as Figure 7As shown, in some embodiments of this 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. A movable shaft 35 is connected to the support base 80 to be fixed to the base 10 via the support base 80.

[0110] In this embodiment, the connecting sleeve 361 and connecting screw 362 of the above embodiments can be omitted, and the end of the movable spring 38 abuts against the side wall of the support 80. The support 80 improves the connection stability of the movable shaft 35 on the base 10, thereby ensuring the stability of the movable part 32 rotating and moving on the movable shaft 35.

[0111] In other embodiments, the connecting sleeve 361, connecting screw 362, and support 80 can be omitted, and the movable shaft 35 and the rotation shaft 21 of the second rotating assembly 202 can be directly integrated into a single shaft structure. This means that the movable part 32 and the rotating plate 221 in the second rotating assembly 202 are assembled using the same shaft. This arrangement effectively improves the assembly accuracy of the locking assembly 30 and the rotating assembly, ensuring that the rotation axis of the movable part 32 and the rotation axis of the rotating plate 221 are collinear.

[0112] The multi-position rotation locking module 100 of this application can be installed as an independent module unit on various devices that require rotation and need to be positioned at a set angle. If the multi-position rotation locking module 100 is applied to medical devices, it can realize the connection between functional components and support components, and can realize the relative rotation between functional components and support components, so that functional components and support components can 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 support 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 closer 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 support component can be adjusted according to the usage requirements. When the positioning part 50 moves into place, it makes a sound similar to "click", which can remind the user whether the movable part 32 has moved to the new locking position, and the user can judge whether the adjustment is in place.

[0114] After adjustment, due to the release of external force and the elastic action of the movable spring 38, the movable spring 38 can abut against the movable part 32 and move along the movable shaft 35 and the fixed shaft 332 toward the direction of approaching the first rotating component 201, so that the movable wheel 322 engages with the locking wheel 31, so that the functional component is positioned and suspended at the required angle position.

[0115] See Figure 8 An embodiment of this application also provides a mobile trolley 1000. The mobile trolley 1000 includes a body 200, wheels 300 disposed at the bottom of the 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 mobile trolley 1000 can move on the ground by rotating the casters 300, making it more flexible to use. The trolley body 200 is the main body of the mobile trolley 1000, and the casters 300 are located at the bottom of the trolley body 200. The multi-position rotation locking module 100 is located on the top of the trolley body 200, and the base 10 is used to connect to the top of the trolley body 200.

[0117] Functional components such as the 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 rotate relative to the vehicle body 200 and be suspended at a set angle position, so that the functional components can be adjusted and positioned relative to the vehicle body 200 to a suitable angle position, thereby facilitating user operation.

[0118] In some examples, the mobile trolley 1000 may also include a support platform 400, which can be configured with different contour shapes, such as 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 operating console, control panel, display screen, touch screen, etc.

[0119] In this example, the fixing member 33 and the connecting member 22 support the functional devices, such as the operating table, control panel, display screen, and touch screen, through the support platform 400. With the support platform 400, there is no need to connect the 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 trolley 1000 more widely applicable.

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

[0121] A portable ultrasound device 2000 is mounted on a support platform 400. The portable ultrasound device 2000 may include a main unit 2001 and a screen 2002, with the screen 2002 rotatably connected to the main unit 2001. Rotation of the screen 2002 relative to the main unit 2001 allows the portable ultrasound device 2000 to be switched to laptop mode. Figure 8 (as shown) and tablet mode ( Figure 9 (As shown).

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

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

[0124] For the multi-position rotation locking module, mobile trolley, and mobile medical device of this application, the multi-position rotation locking module can be flexibly applied as an independent module unit to various devices that need to rotate and be positioned at a set angle. For example, when the multi-position rotation locking module is applied to medical devices, it can realize the connection between functional components and support components, and realize the relative rotation between functional components and support components, so that functional components and support components can be positioned at a set angle, thereby locking the corresponding functional components at the positioning and hovering position. This effectively avoids the situation where the functional components are rotated and deviated due to accidental touch or attenuation caused by repeated or long-term use, ensuring that they are always stably in the hovering position required by the user, making it convenient for users to use efficiently and flexibly.

[0125] Although the invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
