[0051] Embodiment:

[0052] Please refer to Figures 1 to 12 , in this embodiment, an ultrasonic device includes:

[0053] A moving device, the moving device includes a locking device 1;

[0054] A main unit 2, the main unit 2 is detachably connected to the locking device 1.

[0055] Among them, the locking device 1 includes: a main unit bracket 10, a pressing assembly 20 movably connected to the main unit bracket 10, and a first clamping assembly 40;

[0056] The pressing assembly 20 is connected to the first clamping assembly 40;

[0057] The pressing assembly 20 can linearly reciprocate relative to the main unit bracket 10 along a first direction, thereby driving the first clamping assembly 40 to linearly reciprocate along the first direction, so that the clamping portion 422 of the first clamping assembly 40 extends or retracts from the main unit bracket 10;

[0058] The first clamping component 40 further includes an elastic member 41 connected to the host bracket 10, and the elastic member 41 is used to return the clamping portion 422 to the position protruding from the host bracket 10.

[0059] In this embodiment, the linear reciprocating movement of the pressing component 20 can be converted into the linear reciprocating movement of the first clamping component 40, so that the force application direction of the user on the pressing component 20 is the same as the moving direction of the first clamping component 40, effectively simplifying the unlocking operation method, and making the operation method of the pressing component 20 significantly different from the operation methods of other buttons on the mobile device, reducing the risk of misoperation.

[0060] Preferably, the locking device 1 further includes a rotating component 30;

[0061] The first end of the rotating component 30 is rotatably connected to the host bracket 10, and the second end and the third end of the rotating component 30 are respectively movably connected to the pressing component 20 and the first clamping component 40;

[0062] The pressing component 20 can linearly reciprocate relative to the host bracket 10 along a first direction, thereby driving the second end of the rotating component 30 to rotate around the first end of the rotating component 30, and the third end of the rotating component 30 drives the first clamping component 40 to linearly reciprocate along the first direction, so that the clamping portion 422 of the first clamping component 40 protrudes or retracts from the host bracket 10.

[0063] Through the connection of the pressing component 20, the rotating component 30 and the first clamping component 40, the conversion of linear motion, rotational motion and then linear motion is realized. The transmission process of the locking device 1 is smooth and the structural reliability is high.

[0064] In other embodiments, the pressing component 20 and the first clamping component 40 can also be connected through transmission components such as a multi-link component to realize the linear reciprocating movement of the pressing component 20 and the first clamping component 40 in the same direction.

[0065] As Figure 6 shown, further, the mobile device further includes a plurality of second clamping components 15, and the host bracket 10 of the locking device 1 further includes an assembly groove 11. The first clamping component 40 and the second clamping components 15 are respectively arranged on two opposite groove walls of the assembly groove 11;

[0066] As Figures 3 to 5 shown, a plurality of clamping grooves 202 are formed on two opposite side surfaces of the host 2. The clamping portion 422 of the first clamping component 40 and the second clamping components 15 are respectively clamped in the corresponding clamping grooves 202, so that the host 2 is assembled in the assembly groove 11.

[0067] As Figures 4 to 5 shown,Figure 5 The direction of the middle arrow is the first direction. The steps of assembling the host 2 include: aligning the clamping groove 202 of the host 2 corresponding to the second clamping assembly 15 with the second clamping assembly 15, applying force to the pressing assembly 20 along the first direction so that the clamping portion 422 of the first clamping assembly 40 is retracted into the host bracket 10, pressing the host 2 into the assembly groove 11, stopping applying force to the pressing assembly 20 along the first direction, and the clamping portion 422 of the first clamping assembly 40 is restored to the position extending out of the host bracket 10 through the elastic member 41, so that the clamping portion 422 is clamped in the clamping groove 202 corresponding to the first clamping assembly 40, thereby completing the assembly of the host 2 in the mobile device.

[0068] Furthermore, if Figure 1 and 5 As shown, a handle 201 is disposed on one side of the host 2 where the clamping slot 202 is opened. The handle 201 is disposed on a side of the pressing component 20 of the locking device 1 that is away from the first clamping component 40 .

[0069] like Figure 5 As shown, the steps for disassembling the host 2 include: the user holds the handle 201 and continuously applies force to the pressing assembly 20 along the first direction, so that the clamping portion 422 of the first clamping assembly 40 retracts into the host bracket 10, lifts the handle 201, stops applying force to the pressing assembly 20 along the first direction, and removes the host 2 in the assembly slot 11.

[0070] In addition, if Figure 2 As shown, the ultrasonic device further includes a battery assembly 3, which is clamped on the main frame 10. In this embodiment, the battery assembly 3 and the side wall of the main frame 10 are surrounded to form an assembly groove 11, and a plurality of second clamping assemblies 15 are formed on one side of the battery assembly 3 opposite to the first clamping assembly 40.

[0071] It should be noted that in this embodiment, only an example of the locking device 1 loading the ultrasound device host 2 is given. In other embodiments, the locking device 1 can also be used to lock other components of the ultrasound device, or to lock components of other detachable medical devices. For example, the locking device 1 can also be used to lock the battery assembly 3 of the ultrasound device. The components of the ultrasound device 1 are not limited to the battery assembly 3 and the host 2. The second clip assembly 15 is not limited to being set on the battery assembly 3. The second clip assembly 15 can also be set on the host bracket 10 or other components.

[0072] Furthermore, if Figure 4 and 5 As shown, the host bracket 10 includes a first cavity and a second cavity that are connected, the first cavity and the second cavity are spaced apart in a second direction, the second direction forms an angle with the first direction, and the pressing assembly 20 and the first clamping assembly 40 are respectively accommodated in the first cavity and the second cavity;

[0073] The pressing component 20 and the first clamping component 40 are respectively received in the first cavity and the second cavity; a part of the pressing component 20 protrudes from the first cavity, and the clamping part 422 of the first clamping component 40 can extend out of or retract into the second cavity.

[0074] Specifically, as described above, the main machine bracket 10 of the locking device 1 further includes an assembly groove 11. The first clamping component 40 and the second clamping component 15 are respectively arranged on two opposite groove walls of the assembly groove 11. It can be understood that the first cavity and the second cavity are arranged on the groove wall on the same side of the assembly groove 11, and the second cavity communicates with the assembly groove 11 along the first direction, so that the clamping part 422 of the first clamping component 40 can extend from the second cavity into the assembly groove 11, so that the first clamping component 40 can be clamped with the main machine 2 in the assembly groove 11.

[0075] Since the first direction is the moving direction of the pressing component 20 and the first clamping component 40, and the first direction is also the direction in which the user needs to apply force to the pressing component 20, the first cavity and the second cavity are arranged at intervals in the second direction, and the second direction forms an angle with the first direction, so that the locking device 1 in this embodiment is different from the traditional locking device.

[0076] In a traditional locking device, the components for pressing, the components for providing elastic restoring force, and the components for clamping are sequentially connected along the force application direction, and a large space is required in the force application direction.

[0077] However, in the locking device 1 of this embodiment, the pressing component 20 in the first cavity and the first clamping component 40 in the second cavity are arranged at intervals in the second direction, and the second direction forms an angle with the direction in which the user needs to apply force to the pressing component 20. Therefore, in the direction in which the user applies force to the locking device 1, the locking device 1 occupies a smaller space. The linear reciprocating motion of the pressing component 20 in the first cavity is realized, and the rotation motion of the rotating component 30 is converted into the linear reciprocating motion of the first clamping component 40 in the second cavity through the rotation motion of the rotating component 30.

[0078] The advantage of such a setting is that the locking device 1 can be better arranged on the side wall of the main machine bracket 10 of the ultrasonic device, or the side wall of other medical devices, etc. The thickness direction of the side wall of the main machine bracket 10 of the ultrasonic device or the side wall of other medical devices is parallel to the first direction. And compared with the traditional locking device, the locking device 1 in this embodiment has higher structural reliability. On the basis of improving the reliability, the structure is simple, the required components are fewer, and the manufacturing cost is lower.

[0079] It can be understood that in this embodiment, the locking device 1 is provided on the side wall of the main machine bracket 10 of the ultrasonic device only as an example. According to the different positions of the components to be locked in the device in actual applications, the locking device 1 can also be provided at other positions of the main machine bracket 10. The locking device 1 is not limited to locking the main machine 2 of the ultrasonic device. The locking device 1 can also be used in other medical devices with a structure similar to that of the ultrasonic device.

[0080] Preferably, the first direction is perpendicular to the second direction.

[0081] Furthermore, the projection of the pressing component 20 and the first clamping component 40 in the second direction overlaps or intersects.

[0082] Preferably, in this embodiment, the symmetry axes of the projections of the pressing component 20 and the first clamping component 40 in the second direction overlap, which further reduces the space required for the assembly of the locking device 1 in the main machine bracket 10.

[0083] Furthermore, as Figure 7 shown, the locking device 1 includes a plurality of rotating components 30; the axial directions of the first end, the second end, and the third end of each rotating component 30 are parallel to each other. Define the direction perpendicular to the axial direction of the rotating component 30 and the first direction as the width direction of the pressing component 20 and the first clamping component 40. The plurality of rotating components 30 are symmetrically arranged on both sides of the pressing component 20 and the first clamping component 40 in the width direction.

[0084] Figure 7 The directions of the arrows in each indicate the moving directions of the corresponding pressing component 20, the first clamping component 40, and the rotating component 30. As Figure 7 shown, the rotating components 30 are symmetrically arranged on both sides of the pressing component 20 and the first clamping component 40 in the width direction, which can improve the stability of the locking device 1, reduce the risk of unbalanced force distribution caused by the unilateral arrangement of the rotating components 30 or the asymmetric arrangement of multiple rotating components 30, and avoid the deviation of the pressing component 20 or the first clamping component 40 when moving in the first direction.

[0085] Preferably, the pressing component 20 includes a body 21 and two protruding parts 22. The protruding parts 22 are arranged at one end of the body 21 facing the rotating component 30, and the two protruding parts 22 are symmetrically arranged on both sides of the body 21 in the width direction. The second end and the third end of the rotating component 30 are connected to the protruding parts 22.

[0086] With such an arrangement, there will be no interference between the pressing component 20 and the rotating component 30 during movement, avoiding the limitation of the movement between the pressing component 20 and the rotating component 30.

[0087] Furthermore, as Figure 8 、 9As shown in FIGS. 11 and 12, the first clamping component 40 is provided with a first sliding groove 421. The third end of each rotating component 30 protrudes towards the first clamping component 40 with a first rotating shaft 32, and the first rotating shaft 32 is slidably assembled in the first sliding groove 421;

[0088] The second end of the rotating component 30 is provided with a second sliding groove 31. The pressing component 20 is provided with a second rotating shaft 221 towards the rotating component 30, and the second rotating shaft 221 is slidably assembled in the second sliding groove 31.

[0089] In this embodiment, the rotating component 30 is slidably connected to the pressing component 20 and the first clamping component 40 through a rotating shaft and a sliding groove. Since the first clamping component 40 and the pressing component 20 only linearly move in the first direction, the first rotating shaft 32 needs to be slidably assembled with the first sliding groove 421, and the second rotating shaft 221 needs to be slidably assembled with the second sliding groove 31 to prevent interference and limited movement between the components of the locking device 1.

[0090] In addition, the first end of the rotating component 30 protrudes with a third rotating shaft 16, and the third rotating shaft 16 is rotatably connected to the main machine bracket 10.

[0091] As Figure 9 shown, preferably, the length extension direction of the first sliding groove 421 and the second sliding groove 31 forms an angle with the first direction.

[0092] When the pressing component 20 is not stressed, the length extension directions of the first sliding groove 421 and the second sliding groove 31 are perpendicular to the first direction. When a force is applied to the pressing component 20 in the first direction, the angle between the length extension directions of the first sliding groove 421 and the second sliding groove 31 and the first direction decreases. In addition, by limiting the lengths of the first sliding groove 421 and the second sliding groove 31, the linear movement stroke of the pressing component 20 and the first clamping member can also be limited.

[0093] In other embodiments, it is also possible that the first clamping component 40 protrudes the first rotating shaft 32 towards the rotating component 30, and the rotating component 30 is provided with the first sliding groove 421, and / or, it is also possible that the rotating component 30 protrudes the second rotating shaft 221 towards the pressing component 20, and the pressing component 20 is provided with the second sliding groove 31, as long as it satisfies that the rotating component 30 is slidably connected to the first clamping component 40 and between the rotating component 30 and the pressing component 20 through a rotating shaft and a sliding groove, and it is not limited to only the rotating component 30 being provided with a sliding groove or protruding a rotating shaft.

[0094] In this embodiment, preferably, the pressing component 20 and the first clamping component 40 are arranged on both sides of the rotating component 30 along the axial direction of the rotating shaft. However, in other embodiments, the pressing component 20 and the first clamping member can also be arranged on the same side of the rotating component 30 along the axial direction of the rotating shaft.

[0095] Furthermore, asFigures 8 to 11 As shown, a sliding track 12 extending along a first direction is provided in the main frame 10, and a first clamping assembly 40 is slidably assembled on the sliding track 12. The first clamping assembly 40 and the sliding track 12 enclose a receiving cavity, and the elastic member 41 is received in the receiving cavity.

[0096] In this embodiment, there are multiple receiving cavities. Specifically, the first clamping assembly 40 and the sliding track 12 form two receiving cavities. The multiple receiving cavities are symmetrically arranged on both sides of the first clamping assembly 40 along the width direction.

[0097] Specifically, Figures 8 to 11 As shown, the first clamping assembly 40 has two mounting grooves 423 protruding from both sides along the width direction in the direction away from the sliding track 12, and the mounting grooves 423 cover the corresponding sliding track 12. The mounting grooves 423 and the sliding track 12 enclose a receiving cavity, and a baffle 121 is provided at one end of the sliding track 12 away from the first direction. One end of the elastic member 41 abuts against the baffle 121, and the other end is connected to the groove wall of the mounting groove 423 facing the first direction, so that the elastic member 41 is received in the receiving cavity. The mounting groove 423 can slide on the sliding track 12 along the first direction. The matching structure of the sliding track 12 and the first clamping assembly 40 in this embodiment is simple, which reduces the manufacturing cost. The first clamping assembly 40 and the sliding track 12 are detachable, which is convenient for manufacturing and maintenance. Through the matching of the first clamping assembly 40 and the sliding track 12, the movement process of the first clamping assembly 40 is smooth, and the reliability of the locking device 1 is improved.

[0098] Preferably, Figure 9 and 11 As shown, in this embodiment, the mainframe bracket 10 is further provided with a guide groove 13 of the elastic member 41, and the guide groove 13 extends away from the first direction from the baffle 121 of the sliding track 12. A mounting column 4231 is further protruded from the groove wall of the mounting groove 423 facing the first direction, and the mounting column 4231 is interference-fitted with one end of the elastic member 41. The above arrangement can further fix the elastic member 41, improve the stability of the elastic member 41 during the extension and retraction process, and achieve a better locking effect.

[0099] The first clamping assembly 40 can be slidably assembled on the sliding rail 12 in a variety of ways. For example, both sides of the first clamping assembly 40 along the width direction can be clamped on the sliding rail 12.

[0100] In this embodiment, the first clamping assembly 40 is slidably assembled on the sliding rail 12 in the following manner:

[0101] like Figures 8 to 12As shown, the mainframe bracket 10 protrudes towards the first clamping component 40 with a plurality of first protrusions 14. The first clamping component 40 includes a fixing member 43 connected to the first protrusions 14 and a sliding member 42 movably connected between the mainframe bracket 10 and the fixing member 43. The sliding member 42 is provided with a plurality of third sliding grooves 424 extending in the lengthwise direction of the first direction, and each first protrusion 14 passes through each third sliding groove 424.

[0102] In this embodiment, mounting grooves 423 are provided at both ends of the sliding member 42 in the width direction. The fixing member 43 is located between the two mounting grooves 423. It is defined that the thickness direction of the sliding member 42 is perpendicular to the first direction and the axial direction of each rotating shaft of the rotating component 30. It can be understood that since the fixing member 43 is connected to the first protrusions 14, the movement of the sliding member 42 in the thickness direction is restricted, so that the sliding member 42 is slidably assembled onto the sliding track 12. The length extension direction of the third sliding groove 424 is parallel to the first direction.

[0103] The fixing member 43 can be threadedly connected to the first protrusions 14 or connected by other detachable connection means.

[0104] With such a setting, the first clamping component 40 can be detachably connected to the mainframe bracket 10, and the matching structural stability is high.

[0105] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
