[0034] Embodiment 1

[0035] Please refer to Figure 1 and Figure 4 for a description of the chassis provided by the present invention. The chassis, for an ultrasonic diagnostic device, includes a main chassis 1 and an auxiliary chassis 2. An ultrasonic main board 11 is vertically arranged in the main chassis 1, and a first plug-in part 12 is provided on the ultrasonic main board 11. A probe board 21 is vertically arranged in the auxiliary chassis 2, and a second plug-in part 22 is provided on the probe board 21. The main chassis 1 and the auxiliary chassis 2 are arranged along the height direction, and the first plug-in part 12 and the second plug-in part 22 are plugged into each other.

[0036] Compared with the prior art, for the chassis provided by the present invention, the probe board 21 and the ultrasonic main board 11 are separately arranged inside the main chassis 1 and the auxiliary chassis 2, and the ultrasonic main board 11 and the probe board 21 are connected by plugging the first plug-in part 12 and the second plug-in part 22 into each other, thereby connecting the main chassis 1 and the auxiliary chassis 2. After separating the probe board 21 and the ultrasonic main board 11, the probe board 21 can have a larger activity space, that is, there can be a certain height difference between the probe board 21 and the ultrasonic main board 11, and correspondingly, the height of the probe base 23 can also have a larger floating adjustment space in design. Separating the probe board 21 and the ultrasonic main board 11 inside the main chassis 1 and the auxiliary chassis 2 respectively can also make the shielding effect between the probe board 21 and the ultrasonic main board 11 better. The main chassis 1 can slide on the base 5 to realize the mutual connection of the first plug-in part 12 and the second plug-in part 22. During maintenance, only the main chassis 1 needs to be pulled out to realize the maintenance operation, which is convenient for maintenance and assembly, and the overall model can be designed to be thinner and more beautiful.

[0037] Specifically, the height direction refers to the height direction when the chassis is in normal use. The main chassis 1 and the auxiliary chassis 2 are both arranged inside the chassis, and there is a height difference between the main chassis 1 and the auxiliary chassis 2, so that the main chassis 1 and the auxiliary chassis 2 are arranged with a height difference, which can reduce the volume of the entire chassis. And, since there are more boards inside the main chassis 1, its size is larger, and only the probe board 21 is arranged in the auxiliary chassis 2, so its size is smaller. Arranging the main chassis 1 and the auxiliary chassis 2 along the height can make the most of the space and make the entire chassis thinner.

[0038] The mutual connection between the first plug-in part 12 and the second plug-in part 22 can realize the connection of data, electric energy, etc. between the ultrasonic main board 11 and the probe board 21. The ultrasonic main board 11 can not only collect the data information collected by the probe board 21, but also process the data information collected by the probe board 21 and process the ultrasonic information data.

[0039] Further, please refer to Figures 1 to 4, as a specific embodiment of the chassis provided by the present invention, the main chassis 1 further includes a first housing 13, and the ultrasonic main board 11 is disposed inside the first housing 13. The auxiliary chassis 2 includes a second housing 24, and the probe board 21 is disposed inside the second housing 24. The first housing 13 and the second housing 24 are two relatively independent housings. There is a height difference between the first housing 13 and the second housing 24, and the height between the first housing 13 and the second housing 24 can be adjusted according to actual situations. The first housing 13 is used to shield the ultrasonic main board 11, and the second housing 24 is used to shield the probe board 21. A through hole for the first insertion portion 12 to pass through is formed on the first housing 13, and a through hole for the second insertion portion 22 to pass through is also provided on the second housing 24.

[0040] Further, please refer to Figures 1 to 3 , as a specific embodiment of the chassis provided by the present invention, the auxiliary chassis 2 is located above the main chassis 1. The first insertion portion 12 is located at a position of the ultrasonic main board 11 close to the top of the main chassis 1, and the second insertion portion 22 is located at a position of the probe board 21 close to the bottom of the auxiliary chassis 2. Specifically, the auxiliary chassis 2 can be located directly above or obliquely above the main chassis 1, so that there is a height difference between the auxiliary chassis 2 and the main chassis 1, and the entire chassis can be designed to be thinner and lighter. The positions of the first insertion portion 12 and the second insertion portion 22 are respectively set above and below the main chassis 1 and the auxiliary chassis 2, so that the lower part of the auxiliary chassis 2 is inserted into the upper part of the main chassis 1, thereby maximizing the height of the probe board 21. Of course, according to actual situations and specific requirements, in other embodiments of the present invention, the positions of the first insertion portion 12 and the second insertion portion 22 can also be adjusted according to the design requirements of the chassis, and this is not limited to a single case here.

[0041] Further, please refer to Figures 1 to 3, as a specific implementation of the chassis provided by the present invention, the first plugging part 12 passes through the main chassis 1 and the auxiliary chassis 2 and is plugged into the second plugging part 22, or the second plugging part 22 passes through the main chassis 1 and the auxiliary chassis 2 and is plugged into the first plugging part 12. Specifically, the first plugging part 12 and the second plugging part 22 can directly achieve plugging, and there are several pins on the first plugging part 12 or the second plugging part 22, and there are several sockets for accommodating the pins on the second plugging part 22 or the first plugging part 12, so that the first plugging part 12 and the second plugging part 22 can be connected to each other. The first plugging part 12 and the second plugging part 22 are respectively separated in two relatively independent chassis, so the side walls of the main chassis 1 and the auxiliary chassis 2 need to be adopted between the first plugging part 12 and the second plugging part 22. It can be that the first plugging part 12 passes through the side walls of the main chassis 1 and the auxiliary chassis 2, or it can be that the second plugging part 22 passes through the side walls of the main chassis 1 and the auxiliary chassis 2. Of course, according to the actual situation and specific requirements, in other embodiments of the present invention, it can also be that the first plugging part 12 passes through the main chassis 1 and the second plugging part 22 passes through the auxiliary chassis 2, so as to realize the plugging between the first plugging part 12 and the second plugging part 22, and this is not uniquely limited here.

[0042] Further, please refer to Figures 1 to 3 , as a specific implementation of the chassis provided by the present invention, the main chassis 1 further includes a power supply board 15, a computer main board 16 and a motherboard 17. The computer main board 16 and the ultrasonic main board 11 are respectively arranged on both sides of the power supply board 15, and the ultrasonic main board 11, the power supply board 15 and the computer main board 16 are sequentially vertically inserted on the motherboard 17. Specifically, the ultrasonic main board 11, the power supply board 15 and the computer main board 16 are arranged parallel to each other. The motherboard 17 is arranged at the bottom of the ultrasonic main board 11, the power supply board 15 and the computer main board 16, and the motherboard 17 is respectively plugged into the ultrasonic main board 11, the power supply board 15 and the computer main board 16. Among them, the power supply board 15 is used to supply power to the ultrasonic main board 11, the motherboard 17 and the computer main board 16. The computer main board 16 is used to process other information except ultrasonic information in the ultrasonic diagnostic device, such as control information of other software, etc. The motherboard 17 can connect the probe board 21, the ultrasonic main board 11, the power supply board 15 and the computer main board 16, so as to realize overall control.

[0043] Further, please refer to Figures 1 to 3, as a specific implementation of the chassis provided by the present invention, the probe base 23 is located at the upper part of the probe board 21. Specifically, the second plug-in part 22 is located on the probe board 21, and the second plug-in part 22 is used to realize the connection between the probe board 21 and the ultrasonic main board 11. The probe base 23 is used to connect with the probe. By respectively arranging the second plug-in part 22 and the probe base 23 above and below the probe board 21, the height of the probe base 23 can be maximally increased, so that the operator can conveniently perform the operation of plugging and unplugging the probe, which is convenient to use. Of course, according to the actual situation and specific requirements, in other embodiments of the present invention, the second plug-in part 22 and the probe base 23 can also be located at any position of the probe board 21, having a good floating adjustment space in design, and this is not uniquely limited here.

[0044] Further, please refer to Figures 1 to 4 , as a specific implementation of the chassis provided by the present invention, the ultrasonic main board 11, the power board 15 and the computer main board 16 are all arranged inside the main chassis 1. A plurality of shielding plates are arranged inside the main chassis 1, and the ultrasonic main board 11, the power board 15 and the computer main board 16 are separated and shielded by the shielding plates, so as to ensure the mutual shielding effect inside the main chassis 1 and avoid the power board 15 affecting the operation of the ultrasonic main board 11 or the computer main board 16.

[0045] Further, refer to Figures 3 to 6 , as a specific implementation of the chassis provided by the present invention, a guiding structure for inserting the first plug-in part 12 and the second plug-in part 22 is further provided between the ultrasonic main board 11 and the probe board 21. Specifically, the guiding structure can guide the connection between the first plug-in part 12 and the second plug-in part 22, so as to ensure that the first plug-in part 12 can be smoothly and accurately inserted into the second plug-in part 22, and avoid the problems of pin bending or difficult insertion caused by the direct insertion of the first plug-in part 12 and the second plug-in part 22.

[0046] Further, refer to Figures 3 to 6 , as a specific implementation of the chassis provided by the present invention, the guiding structure includes a positioning post 3 arranged on the ultrasonic main board 11 and a first fixing hole 211 opened on the probe board 21 for the positioning post 3 to pass through. Specifically, the positioning post 3 can pass through the first fixing hole 211 when the main chassis 1 moves towards the auxiliary chassis 2, so as to play a role of auxiliary positioning and avoid the problems of pin bending or difficult insertion caused by the direct insertion of the first plug-in part 12 and the second plug-in part 22. Of course, according to the actual situation and specific requirements, in other embodiments of the present invention, the first plug-in part 12 and the second plug-in part 22 can also be directly inserted or magnetic parts are arranged on the probe board 21 and the ultrasonic main board 11, and the relative position between the probe board 21 and the ultrasonic main board 11 is limited by the magnetic attraction of the magnetic parts, and this is not uniquely limited here.

[0047] Further, please refer to Figures 3 to 5 , as a specific implementation of the chassis provided by the present invention, the positioning post 3 includes a first fixing post 31 and a first conical post 32 located at one end of the first fixing post 31 away from the ultrasonic main board 11, and the first fixing post 31 and the first conical post 32 are fixedly connected. Specifically, the first fixing post 31 is used to pass through the first fixing hole 211, the first conical post 32 is arranged at the end of the first fixing post 31, and the diameter of the side of the first conical post 32 close to the first fixing post 31 is greater than that of the side of the first conical post 32 away from the first fixing post 31. Thus, through the setting of the first conical post 32, the effect of auxiliary guiding can be achieved, ensuring that the first fixing post 31 can be concentric with the first fixing hole 211, and having a good guiding effect.

[0048] Further, please refer to Figures 3 to 5 , as a specific implementation of the chassis provided by the present invention, a fixing sleeve 4 is arranged in the first fixing hole 211, the fixing sleeve 4 is fixedly connected with the probe board 21, and a limiting hole 43 for the positioning post 3 to pass through is arranged in the fixing sleeve 4. Specifically, the fixing sleeve 4 is fixed on the probe board 21, and the fixing sleeve 4 can be arranged inside the first fixing hole 211. The positioning post 3 can pass through the first fixing hole 211 inside the fixing sleeve 4. Thus, through the fixing sleeve 4, it can be avoided that the positioning post 3 directly abuts against the probe board 21, and the situation that the probe board 21 may be worn due to the direct abutment of the positioning post 3 and the probe board 21 is avoided, effectively protecting the probe board 21.

[0049] Further, refer to Figures 3 to 5 , as a specific implementation of the chassis provided by the present invention, the fixing sleeve 4 includes a limiting cover 41 and a connecting portion 42 connected to one end of the limiting cover 41. The limiting hole 43 penetrates through the connecting portion 42 and the limiting cover 41. One end of the limiting cover 41 close to the connecting portion 42 abuts against the probe board 21, and the connecting portion 42 passes through the first fixing hole 211. Specifically, the limiting cover 41 and the probe board 21 are fixedly connected by fixing parts such as bolts, screws or hooks, and the connecting portion 42 and the limiting cover 41 are fixedly connected by integral molding or bonding. Among them, the limiting cover 41 is arranged on the side of the probe board 21 away from the ultrasonic main board 11, the connecting portion 42 passes through the first fixing hole 211 and is connected to the positioning post 3, and the limiting hole 43 is arranged in the connecting portion 42. Through the connecting portion 42, the positioning post 3 and the fixing sleeve 4 can be conveniently connected, so that the moving path of the main chassis 1 can be limited, and it is avoided that the first plugging portion 12 and the second plugging portion 22 cannot be directly opposite. The positioning between the ultrasonic main board 11 and the probe board 21 is assisted by the cooperation of the positioning post 3 and the limiting sleeve.

[0050] Preferably, the connecting portion 42 extends through the first fixing hole 211 to the ultrasonic main board 11, and the limiting hole 43 is arranged in the connecting portion 42. The connecting portion 42 extending to the ultrasonic main board 11 can guide the movement of the positioning post 3, thereby avoiding the phenomenon that the first plugging portion 12 and the second plugging portion 22 cannot be directly opposite to each other, and realizing the positioning between the ultrasonic main board 11 and the probe board 21.

[0051] Further, please refer to Figures 3 to 5 , as a specific embodiment of the chassis provided by the present invention, a limiting protrusion 411 is arranged on the limiting cover 41, and a limiting groove 212 for accommodating the limiting protrusion 411 is arranged on the probe board 21. Specifically, through the matching structure of the limiting protrusion 411 and the limiting groove 212, the rotation of the limiting cover 41 can be restricted, thereby ensuring the stability of the connection between the limiting cover 41 and the probe board 21. Among them, the limiting cover 41 and the probe board 21 are connected by a plurality of bolts surrounding the connecting portion 42. Through holes corresponding to the bolts are arranged on the probe board 21, and the through holes can be communicated with the limiting groove 212, which can facilitate the processing of the limiting groove 212 and the through holes.

[0052] Preferably, the shape of the limiting cover 41 is non-circular, and at least two bolts are arranged on the limiting cover 41 surrounding the connecting portion 42, so as to avoid the relative rotation of the limiting cover 41 on the probe board 21 and ensure the connection stability between the limiting cover 41 and the probe board 21.

[0053] Further, please refer to Figure 2 and Figure 6 , as a specific embodiment of the chassis provided by the present invention, the positioning post 3 is located on opposite sides of the first plugging portion 12. Specifically, the number of the positioning posts 3 is two or a multiple of two. A plurality of positioning posts 3 are arranged at intervals on opposite sides of the first plugging portion 12 in turn; the number of the fixing sleeves 4 is two or a multiple of two. A plurality of fixing sleeves 4 are arranged at intervals on opposite sides of the second plugging portion 22 in turn. Through the cooperation of two or more positioning posts 3 and fixing sleeves 4, the accuracy of the guiding can be ensured, and the plugging between the first plugging portion 12 and the second plugging portion 22 can be completed.

[0054] Further, please refer to Figure 2 and Figure 6, as a specific implementation of the chassis provided by the present invention, it further includes a base 5 provided at the bottom of the main chassis 1. The base 5 is slidably connected to the main chassis 1. The base 5 is also provided with a limiting structure for restricting the main chassis 1 from moving forward further after the first insertion part 12 and the second insertion part 22 are inserted. Specifically, the main chassis 1 and the auxiliary chassis 2 are two relatively independent boxes, and the main chassis 1 and the auxiliary chassis 2 are connected by the first insertion part 12 and the second insertion part 22. The moving position of the main chassis 1 can be limited by the limiting structure to avoid the distance between the main chassis 1 and the probe board 21 being too small, thus causing damage to the first insertion part 12 or the second insertion part 22. Among them, one end of the limiting structure is fixed on the base 5, and the other end can abut against the main chassis 1.

[0055] During the assembly operation, the auxiliary chassis 2 is fixed at the designed position to ensure that the height of the probe holder 23 is suitable for the operator to use. Then, the main chassis 1 is pushed from the base 5 to one side of the auxiliary chassis 2, and the first insertion part 12 and the second insertion part 22 are inserted and combined. Moreover, when using the ultrasonic diagnostic device, the probe board 21 is not easily damaged, and components such as the ultrasonic main board 11 are easily damaged. During maintenance, only the main chassis 1 needs to be pulled out to perform the maintenance operation, avoiding the problem that the probe board 21 is repeatedly stretched, resulting in multiple lines being forced to be pulled out, and it is possible to more conveniently achieve maintenance and assembly operations.

[0056] Further, please refer to Figure 3 and Figure 7 , as a specific implementation of the ultrasonic diagnostic device provided by the present invention, the limiting structure is a limiting column 7 provided on the base 5 and abutting against the main chassis 1. Specifically, the limiting column 7 is located below the auxiliary chassis 2, and the limiting column 7 is fixedly connected to the base 5. The moving position of the main chassis 1 can be limited by the limiting column 7 to avoid the distance between the main chassis 1 and the probe board 21 being too small, thus causing damage to the first insertion part 12 or the second insertion part 22. The left and right positions of the main chassis 1 are limited by the setting of the chute 51 and the sliding plate 14, and the forward position of the main chassis 1 can be limited by the limiting column 7, thereby ensuring the position of the main chassis 1 during the assembly process.

[0057] Further, please refer to Figure 3 and Figure 7, as a specific embodiment of the ultrasonic diagnostic device provided by the present invention, the limiting column 7 includes a second fixing column 71 and a second conical column 72 at one end close to the main chassis 1, and the second conical column 72 and the second fixing column 71 are fixedly connected. Specifically, the second fixing column 71 is fixedly connected to the base 5, and the diameter of the second conical column 72 on the side close to the second fixing column 71 is larger than that on the side far from the second fixing column 71. The side of the second conical column 72 far from the second fixing column 71 can abut against the main chassis 1, and the second conical column 72 is arranged parallel to the base 5, which can ensure the position stability of the second conical column 72, and by reducing the contact area between the limiting column 7 and the main chassis 1, the relative position of the main chassis 1 can be ensured, and wear between the outer surface of the main chassis 1 and the limiting column 7 can be avoided.

[0058] Further, refer to Figure 6 and Figure 7 , as a specific embodiment of the ultrasonic diagnostic device provided by the present invention, sliding plates 14 or sliding grooves 51 extend from both sides of the bottom of the main chassis 1, and sliding grooves 51 or sliding plates 14 for cooperating with the sliding plates 14 or sliding grooves 51 are provided on the upper surface of the base 5. Specifically, when the sliding plates 14 are located on both sides of the bottom of the main chassis 1 and these two sides are perpendicular to the auxiliary chassis 2, the sliding grooves 51 are provided on the base 5 for cooperating with the sliding plates 14, so as to ensure that the main chassis 1 can move in the direction of the auxiliary chassis 2, and then the pushing and pulling operation of the main chassis 1 can be realized, which is convenient for assembly. The position of the main chassis 1 can be limited by the sliding grooves 51 and the sliding plates 14, so as to initially ensure the relative position between the main chassis 1 and the auxiliary chassis 2, and then the position between the main chassis 1 and the auxiliary chassis 2 is further limited by the positioning columns 3 and the fixing sleeves 4, so as to ensure that the first insertion part 12 and the second insertion part 22 can be inserted smoothly. It is also possible to provide sliding grooves 51 at the bottom of the main chassis 1 and sliding plates 14 for cooperating with the sliding grooves 51 on the upper surface of the base 5, so as to ensure that the main chassis 1 can move in the direction of the auxiliary chassis 2, and then the pushing and pulling operation of the main chassis 1 can be realized, which is convenient for assembly

The sliding grooves 51 are located on the upper surface of the base 5. The sliding grooves 51 include a limiting plate parallel to the base 5 and a support plate supporting the limiting plate. The support plate is perpendicular to the limiting plate and the base 5, so that a gap is formed between the limiting plate and the base 5, and the sliding plates 14 can extend into the gap between the limiting plate and the base 5. Among them, a guiding plate can be further provided at one end of the limiting plate far from the probe plate 21.

Specifically, the support columns 6 are perpendicular to the base 5. The support columns 6 can support the outer shell and the probe board 21, and the support columns 6 are arranged at the four corners of the base 5. At the same time, the support columns 6 can also fix the main chassis 1 and the auxiliary chassis 2. The exteriors of the main chassis 1 and the auxiliary chassis 2 are both fixedly connected to the support columns 6, and the auxiliary chassis 2 is hung above the front end face of the main chassis 1 through the support columns 6, which can not only enable a fixed connection between the main chassis 1 and the auxiliary chassis 2, but also ensure a height difference between the auxiliary chassis 2 and the main chassis 1. Of course, according to actual situations and specific requirements, in other embodiments of the present invention, a heightening plate can also be provided at the bottom of the auxiliary chassis 2 to achieve a fixed connection between the main chassis 1 and the auxiliary chassis 2 through this heightening plate, and also ensure a height difference between the auxiliary chassis 2 and the main chassis 1. There is no unique limitation here.

The connection between the ultrasonic main board 11 and the probe board 21 is realized through the front end plate 18, which can ensure the mutual shielding effect between the ultrasonic main board 11 and the probe board 21, and can be applicable to more models. Among them, the front end plate 18 is used to collect the information collected by the probes on the probe board 21 and transmit the information to the ultrasonic main board 11, so as to realize the connection between the ultrasonic main board 11 and the probe board 21, and the ultrasonic main board 11 processes the ultrasonic information.

[0063] Furthermore, please refer to Figures 1 to 4 , as a specific implementation of the chassis provided by the present invention, a first housing 13 is sleeved outside the ultrasonic main board 11 and the front end plate 18, and a second housing 24 is sleeved outside the probe board 21.

Specifically, the auxiliary chassis 2 can be located directly above or obliquely above the main chassis 1, so that there is a height difference between the auxiliary chassis 2 and the main chassis 1, making the whole chassis more slender and lightweight. The positions of the first plugging part 12 and the second plugging part 22 are respectively set above and below the main chassis 1 and the auxiliary chassis 2, so that the lower part of the auxiliary chassis 2 is plugged into the upper part of the main chassis 1, thereby maximizing the height of the probe board 21. Of course, according to the actual situation and specific requirements, in other embodiments of the present invention, the positions of the first plugging part 12 and the second plugging part 22 can also be adjusted according to the design requirements of the chassis, which is not limited uniquely here.

There are several pins on the first plugging part 12 or the second plugging part 22, and there are several sockets on the second plugging part 22 or the first plugging part 12 for accommodating the pins, so that the first plugging part 12 and the second plugging part 22 can be connected to each other. The first plugging part 12 and the second plugging part 22 are respectively separated in two relatively independent chassis, so the side walls of the main chassis 1 and the auxiliary chassis 2 need to be penetrated between the first plugging part 12 and the second plugging part 22. It can be that the first plugging part 12 passes through the side walls of the main chassis 1 and the auxiliary chassis 2, or the second plugging part 22 passes through the side walls of the main chassis 1 and the auxiliary chassis 2. Of course, according to the actual situation and specific requirements, in other embodiments of the present invention, it can also be that the first plugging part 12 passes through the main chassis 1 and the second plugging part 22 passes through the auxiliary chassis 2 to realize the plugging between the first plugging part 12 and the second plugging part 22, which is not limited uniquely here.

[0066] Further, please refer to Figures 1 to 4, as a specific embodiment of the chassis provided by the present invention, the main chassis 1 further includes a power supply board 15, a computer motherboard 16, and a motherboard 17.

Among them, the power supply board 15 is used to supply power to the ultrasonic motherboard 11, the motherboard 17, and the computer motherboard 16. The computer motherboard 16 is used to process other information except ultrasonic information in the ultrasonic diagnostic device, such as control information of other software, etc. The motherboard 17 can connect the probe board 21, the ultrasonic motherboard 11, the power supply board 15, and the computer motherboard 16, so as to achieve overall control.

[0067] Further, refer to Figures 3 to 6 , as a specific embodiment of the chassis provided by the present invention, a guiding structure for inserting the first insertion portion 12 and the second insertion portion 22 is further provided between the front panel 18 and the probe board 21. Specifically, the guiding structure can guide the connection between the first insertion portion 12 and the second insertion portion 22, so as to ensure that the first insertion portion 12 can be stably and accurately inserted into the second insertion portion 22, and avoid problems such as the insertion pins being bent or difficult to insert caused by the direct insertion of the first insertion portion 12 and the second insertion portion 22.

[0068] Further, refer to Figures 3 to 6 , as a specific embodiment of the chassis provided by the present invention, the guiding structure includes a positioning post 3 arranged on the front panel 18 and a first fixing hole 211 opened on the probe board 21 for the positioning post 3 to pass through. Specifically, the positioning post 3 can pass through the first fixing hole 211 when the main chassis 1 moves towards the auxiliary chassis 2, so as to achieve the function of auxiliary positioning, and avoid problems such as the insertion pins being bent or difficult to insert caused by the direct insertion of the first insertion portion 12 and the second insertion portion 22. Of course, according to the actual situation and specific requirements, in other embodiments of the present invention, the first insertion portion 12 and the second insertion portion 22 can also be directly inserted, or magnetic parts are provided on the probe board 21 and the front panel 18, and the relative position between the probe board 21 and the front panel 18 is limited by the magnetic attraction of the magnetic parts. This is not the only limitation here.

[0069] Further, please refer to Figures 3 to 5, as a specific embodiment of the chassis provided by the present invention, the positioning post 3 includes a first fixing post 31 and a first tapered post 32 located at one end of the first fixing post 31 away from the front end plate 18, and the first fixing post 31 and the first tapered post 32 are fixedly connected. Specifically, the first fixing post 31 is used to pass through the first fixing hole 211, the first tapered post 32 is arranged at the end of the first fixing post 31, and the diameter of the side of the first tapered post 32 close to the first fixing post 31 is greater than the side of the first tapered post 32 away from the first fixing post 31. Thus, the effect of auxiliary guiding can be achieved through the setting of the first tapered post 32, ensuring that the first fixing post 31 can be concentric with the first fixing hole 211, and having a good guiding effect.

[0070] Further, please refer to Figures 3 to 5 , as a specific embodiment of the chassis provided by the present invention, a fixing sleeve 4 is arranged in the first fixing hole 211. The fixing sleeve 4 is fixedly connected with the probe board 21, and a limiting hole 43 for the positioning post 3 to pass through is arranged in the fixing sleeve 4. Specifically, the fixing sleeve 4 is fixed on the probe board 21, and the fixing sleeve 4 can be arranged inside the first fixing hole 211. The positioning post 3 can pass through the first fixing hole 211 inside the fixing sleeve 4. Thus, the fixing sleeve 4 can prevent the positioning post 3 from directly abutting against the probe board 21, avoiding the situation that the probe board 21 may be worn due to the direct abutment of the positioning post 3 and the probe board 21, and effectively protecting the probe board 21.

[0071] Further, refer to Figures 3 to 5 , as a specific embodiment of the chassis provided by the present invention, the fixing sleeve 4 includes a limiting cover 41 and a connecting portion 42 connected to one end of the limiting cover 41.

One end of the limiting cover 41 close to the connecting portion 42 abuts against the probe board 21, and the connecting portion 42 passes through the first fixing hole 211. Specifically, the limiting cover 41 and the probe board 21 are fixedly connected by fixing members such as bolts, screws or hooks. The connecting portion 42 and the limiting cover 41 are fixedly connected by integral molding or bonding. Among them, the limiting cover 41 is arranged on the side of the probe board 21 away from the ultrasonic main board 11. The connecting portion 42 passes through the first fixing hole 211 and is connected to the positioning post 3. The limiting hole 43 is arranged in the connecting portion 42. The positioning post 3 and the fixing sleeve 4 can be conveniently connected through the connecting portion 42, so as to limit the moving path of the main chassis 1 and avoid the situation that the first plugging portion 12 and the second plugging portion 22 cannot be directly opposite. The positioning between the ultrasonic main board 11 and the probe board 21 is assisted by the cooperation of the positioning post 3 and the limiting sleeve.

[0072] Preferably, the connecting portion 42 extends through the first fixing hole 211 to the front end plate 18, and the limiting hole 43 is arranged in the connecting portion 42. The movement of the positioning post 3 can be guided through the connecting portion 42 extending to the ultrasonic main board 11, so as to avoid the phenomenon that the first plugging portion 12 and the second plugging portion 22 cannot be directly opposite to each other, and the positioning between the ultrasonic main board 11 and the probe board 21 is realized.

[0073] Further, please refer to Figures 3 to 5 , as a specific implementation manner of the chassis provided by the present invention, a limiting protrusion 411 is arranged on the limiting cover 41, and a limiting groove 212 for accommodating the limiting protrusion 411 is arranged on the probe board 21. Specifically, through the matching structure of the limiting protrusion 411 and the limiting groove 212, the rotation of the limiting cover 41 can be restricted, so as to ensure the connection stability between the limiting cover 41 and the probe board 21. Among them, the limiting cover 41 and the probe board 21 are connected by a plurality of bolts surrounding the connecting portion 42. Through holes corresponding to the bolts are arranged on the probe board 21, and the through holes can be communicated with the limiting groove 212, which can facilitate the processing of the limiting groove 212 and the through holes.

[0074] Preferably, the shape of the limiting cover 41 is non-circular, and at least two bolts are arranged on the limiting cover 41 surrounding the connecting portion 42, so as to avoid the relative rotation of the limiting cover 41 on the probe board 21 and ensure the connection stability between the limiting cover 41 and the probe board 21.

[0075] Further, please refer to Figure 2 and Figure 6 , as a specific implementation manner of the chassis provided by the present invention, the positioning posts 3 are located on opposite sides of the first plugging portion 12. Specifically, the number of the positioning posts 3 is two or a multiple of two.

A plurality of fixing sleeves 4 are arranged at intervals on opposite sides of the second plugging portion 22 in sequence. Through the cooperation of two or more positioning posts 3 and fixing sleeves 4, the accuracy of the guiding can be ensured, and the plugging between the first plugging portion 12 and the second plugging portion 22 can be completed.

[0078] The ultrasonic diagnostic device provided by the present invention separates the probe board 21 and the ultrasonic main board 11 inside the main chassis 1 and the auxiliary chassis 2 respectively, and connects the ultrasonic main board 11 and the probe board 21 by inserting them into each other through the first insertion part 12 and the second insertion part 22, thereby connecting the main chassis 1 and the auxiliary chassis 2. This can not only provide a large movement space for the probe board 21, enabling a large floating adjustment space for the height of the probe holder 23 in design, but also achieve a better shielding effect between the probe board 21 and the ultrasonic main board 11. The main chassis 1 can slide on the base 5 to realize the mutual connection of the first insertion part 12 and the second insertion part 22. During maintenance, only the main chassis 1 needs to be pulled out to perform the maintenance operation, which is convenient for maintenance and assembly, and can make the overall model design thinner, lighter and more beautiful.
