[0002] Ultrasonic equipment typically includes a control panel and a display screen. The display screen is located on one side of the control panel, and the connection between the display screen and the control panel is usually a recessed design, meaning the bottom of the display screen is inserted under the keyboard cover of the control panel.

[0003] To facilitate viewing the information displayed on the screen, the display is typically rotatable to adjust to a suitable viewing angle. However, the recessed design creates a gap between the control panel and the display, allowing dust and other impurities to easily enter and making cleaning difficult. Furthermore, the recessed design makes replacing the display or control panel inconvenient; both require removing the entire control panel. Utility Model Content

[0004] One objective of this invention is to provide an ultrasonic device that facilitates the disassembly and assembly of the control panel and display screen, as well as cleaning and maintenance.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An ultrasonic device, comprising:

[0007] control Panel;

[0008] The support includes a fixing structure and a connecting structure connected to the fixing structure, wherein the fixing structure is located inside the control panel and the connecting structure is arranged outside the control panel;

[0009] A display screen electrically connected to the control panel, the display screen being flip-mounted onto the connection structure of the support.

[0010] In one exemplary embodiment, the ultrasonic device includes a connecting shaft fixed to the connecting structure and a connector rotatably disposed on the connecting shaft. The axis of rotation of the connector is collinear with the axis of the connecting shaft. The connector is connected to the display screen, such that the display screen can rotate relative to the support following the connector.

[0011] In an exemplary embodiment, the connection structure includes a support portion and a connecting portion, the connecting portion protruding from the side of the support portion away from the control panel, the support portion and the connecting portion forming a stepped structure, and the connecting shaft being disposed on the stepped structure.

[0012] In one exemplary embodiment, the ultrasonic device includes a fastener that connects the connection portion and the connecting shaft from one side of the connection portion away from the control panel toward the opposite side.

[0013] In one exemplary embodiment, the connecting shaft includes a shaft body and a limiting post protruding from the shaft body; the connecting part is provided with a limiting hole that cooperates with the limiting post.

[0014] In one exemplary embodiment, the ultrasound device includes a fixing member: the fixing structure includes a main body and an extension disposed at an end of the main body, the main body is inclined, and the extension is mounted inside the control panel via the fixing member.

[0015] In one exemplary embodiment, the connecting shaft includes a shaft body portion and a base portion disposed on the shaft body portion; the diameter of the base portion is larger than the diameter of the shaft body portion;

[0016] The connector includes a rotating plate rotatably sleeved on the shaft portion, and the rotating plate is provided with a limiting protrusion;

[0017] The ultrasonic device is provided with a limiting washer, which is sleeved on the shaft part and arranged between the rotating plate and the base part; the limiting washer is provided with a limiting opening, which extends along the circumference of the limiting washer; the limiting protrusion moves within the limiting opening following the rotating plate.

[0018] In one exemplary embodiment, the connection assembly includes a seal for sealing the end of the fastener; the seal includes a sealing plate and a protrusion disposed on the sealing plate; the connection portion is provided with a mounting groove for receiving the sealing plate and a first connection hole for receiving the protrusion; the side surface of the sealing plate opposite to the protrusion is flush with the surface of the connection end.

[0019] In one exemplary embodiment, the connection structure is provided with a cable passage extending through both ends thereto, the cable passage being used to connect the display screen through which the cable passes.

[0020] In one exemplary embodiment, the support includes a support member that protrudes from the fixed structure and whose upper surface abuts against the inner wall of the control panel.

[0021] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects:

[0022] The ultrasonic device of this invention includes a control panel, a support, and a display screen. The fixing structure of the support is located inside the control panel, while the connecting structure of the support is located outside the control panel. The display screen is connected to the connecting structure of the support. In other words, the display screen is completely and independently installed outside the control panel. Therefore, when the display screen needs to be inspected or replaced, the user only needs to disconnect the connection between the display screen and the support, without needing to remove the control panel. The display screen can be installed and removed independently of the control panel, facilitating operation, effectively reducing the complexity of disassembly and assembly, and improving the efficiency of disassembly, assembly, and maintenance.

[0023] Furthermore, the display screen is rotatably connected to the support structure, allowing users to easily adjust the screen's angle and position. This facilitates cleaning the space between the bottom of the display screen and the control panel surface, including the connection structure of the support outside the control panel and the connection point between the display screen and the support. It is understood that this application eliminates the space between the control panel and the display screen required for smooth rotation when the display screen and control panel are designed in a recessed manner in the prior art. This effectively solves the problem that dust and other impurities can easily enter the control panel through this space, making cleaning difficult. Attached Figure Description

[0034] 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.

[0035] Please see Figure 1One embodiment of this application provides an ultrasonic device 100, including a control panel 10, a support 20, and a display screen 30.

[0036] The display screen 30 is used to display images, data, and other information, allowing users to visually view various diagnostic and testing information. The display screen 30 is electrically connected to the control panel 10. The control panel 10 typically has multiple buttons or knobs for controlling and adjusting various functions of the ultrasound equipment 100, including but not limited to adjusting the quality of the image displayed on the display screen 30.

[0037] It should be noted that the display screen 30 can be a touch screen, allowing users to input commands by touching the display screen 30 or operate the control panel 10 to display corresponding images, data, and other information. Alternatively, the display screen 30 can be a passive display cover 12, allowing users to display corresponding images and other information only by operating the control panel 10. This embodiment uses a touch screen display screen 30 as an example for explanation.

[0038] See Figure 2 and Figure 3 The display screen 30 is connected to the control panel 10 via a support 20. Specifically, in this embodiment, a support 20 is provided. One end of the support 20 is connected to the control panel 10, and the other end is connected to the middle of the display screen 30 to better support the display screen 30.

[0039] In other embodiments, multiple supports 20 may be provided to ensure the stability of the display screen 30. For example, two supports 20 may be provided, with each support 20 connected to one of the two ends of the display screen 30.

[0040] Please see Figure 3 , Figure 4 The support 20 includes a fixing structure 21, which is located inside the control panel 10 and is fastened to the control panel 10.

[0041] Specifically, please refer to Figure 2 The control panel 10 includes a bottom shell 11 and a cover plate 12, which together form a receiving cavity. A fixing structure 21 is located within the receiving cavity. See [link / reference]. Figure 3 A mounting portion 111 protrudes from the side of the bottom shell 11 near the receiving cavity, and the mounting portion 111 has mounting holes. See Figure 4 The fixing structure 21 includes a main body 211 and an extension 212 located at the end of the main body 211.

[0042] The ultrasonic device 100 includes a fixing member 50. An extension 212 is mounted inside the control panel 10 via the fixing member 50. Specifically, the extension 212 has a connecting hole 212a. The fixing member 50 passes through the corresponding connecting hole 212a and mounting hole, thereby connecting and fixing the fixing structure 21 of the support 20 inside the control panel 10. The fixing member 50 can be a screw, pin, etc. The mounting hole and connecting hole can be correspondingly configured as screw holes, pin holes, etc.

[0043] Specifically, in this embodiment, two extension portions 212 are provided, which are respectively connected to the two side edges of the main body 211. Each extension portion 212 extends away from the main body 211 to increase the contact area between the support 20 and the control panel 10, thereby further ensuring the stability of the support 20. Multiple connection holes 212a may be provided on the extension portion 212. Correspondingly, multiple mounting holes are also provided. Multiple fasteners 50 are used to pass through the connection holes 212a and the mounting holes respectively, further increasing the tightness of the connection between the support 20 and the control panel 10, thereby helping to ensure the stability of the display screen 30 mounted on the support 20.

[0044] Please see Figure 3 and Figure 4 In some embodiments, the extension 212 is provided with a positioning hole 212b. The bottom shell 11 of the control panel 10 is provided with a positioning post 112 that can be accommodated in the positioning hole 212b. The positioning post 112 cooperates with the positioning hole 212b, so that the support 20 can be pre-installed inside the control panel 10, which is beneficial for the subsequent convenient assembly of the connector 42.

[0045] See Figure 4 For example, the main body 211 is inclined. For instance, one end of the main body 211 near the center of the bottom shell 11, and the other end extends obliquely upwards. This inclined arrangement of the main body 211 helps to distribute the weight of the display screen 30, thereby better supporting the display screen 30 and contributing to its stability. In other embodiments, the main body 211 may also be arranged perpendicular to the surface of the control panel 10, as long as the fixing structure 21 can be securely connected to the interior of the control panel 10.

[0046] Please see Figure 5 In some embodiments, the main body 211 of the fixing structure 21 is provided with a groove 211a on the side near the bottom shell 11. The groove 211a is beneficial to the weight reduction of the support 20.

[0047] In some embodiments, the support 20 includes a support member 22, which protrudes from the main body 211 of the fixing structure 21. The support member 22 supports the cover plate 12 of the control panel 10 and prevents the cover plate 12 from collapsing. Specifically, support members 22 protrude from opposite sides of the main body 211. The upper surface of the support member 22 abuts against the inner wall of the control panel 10. Specifically, the upper surface of the support member 22 abuts against the surface of the cover plate 12 near the bottom shell 11.

[0048] For example, the cross-section of the support member 22 is triangular, thereby enhancing the structural strength of the support member 22 to more stably support the cover plate 12.

[0049] See Figure 4 and Figure 6 The support 20 includes a connecting structure 23. The connecting structure 23 is connected to the end of the main body 211 in the fixed structure 21 away from the bottom shell 11, and is located outside the control panel 10. The display screen 30 is connected to the connecting structure 23. It can be understood that the display screen 30 is independently located outside the control panel 10. This arrangement not only makes the assembly of the ultrasonic equipment 100 more flexible and quick, but also facilitates the inspection and replacement of the display screen 30. When the display screen 30 needs to be inspected or replaced, only the connection between the display screen 30 and the support 20 needs to be disassembled, without damaging the integrity of the control panel 10, greatly reducing the workload of the operator.

[0050] Specifically, see Figure 3 The cover plate 12 of the control panel 10 is provided with a through hole 121, and the connecting structure 23 passes through the through hole 121 and is located outside the control panel 10. For example, the shape of the through hole 121 is the same as or similar to the outline of the cross-section of the connecting structure 23, so that the peripheral sidewall corresponding to the through hole 121 can be as close as possible to the connecting structure 23 or directly abut against the outer wall of the connecting structure 23. This can effectively reduce the entry of external dust and other impurities into the interior of the control panel 10 through the gap between the connecting structure 23 and the peripheral sidewall corresponding to the through hole 121, which is beneficial to extending the service life of the control panel 10.

[0051] Furthermore, the display screen 30 is rotatably connected to the connection structure 23 of the support 20, so that the display surface of the display settings can rotate relative to the surface of the control panel 10, making it convenient for the user to adjust the tilt angle of the display screen 30 according to the actual situation and their own habits, so that the user can clearly view the display screen 30.

[0052] Furthermore, users can easily adjust the angle and position of the display screen 30, which facilitates cleaning the space between the bottom of the display screen 30 and the surface of the control panel 10, including the connection structure 23 of the support 20 located outside the control panel 10, and the connection between the display screen 30 and the support 20. It can be understood that this application eliminates the space between the control panel 10 and the display screen 30 in the prior art when the display screen 30 and control panel 10 are designed with a recessed shape, which is necessary to ensure smooth rotation of the display screen 30. This effectively solves the problem that dust and other impurities can easily enter the interior of the control panel 10 through the space, making cleaning difficult.

[0053] Specifically, please refer to Figure 4 , Figure 6 The display screen 30 is rotatably connected to the connecting structure 23 via the connecting assembly 40. The connecting assembly 40 includes a connecting shaft 41 fixed to the connecting structure 23 and a connector 42 rotatably disposed on the connecting shaft 41. The axis of rotation of the connector 42 is collinear with the axis of the connecting shaft 41. The connector 42 is connected to the display screen 30, so that the display screen 30 can rotate relative to the support 20 with the connector 42.

[0054] For example, the connection structure 23 includes a support portion 231 and a connection portion 232. The connection portion 232 protrudes from the support portion 231 on the side away from the control panel 10, and the support portion 231 and the connection portion 232 form a stepped structure, with the connecting shaft 41 disposed on the stepped structure.

[0055] It should be noted that the support part 231 and the connecting part 232 can be integrally formed.

[0056] In some embodiments, the surface of the support portion 231 is flat. The connecting shaft 41 includes a shaft body portion 411. The middle portion of the shaft body portion 411 is placed on the support portion 231 in the connecting structure 23, and the axis of the shaft body portion 411 is parallel to the surface of the support portion 231. The surface of the shaft body portion 411 near the support portion 231 is also flat, ensuring sufficient contact between the shaft body portion 411 and the support portion 231, which is beneficial for the connecting structure 23 to stably support the connecting shaft 41.

[0057] For example, the surface of the support portion 231 that abuts against the shaft portion 411 is also parallel to the bottom end face of the fixing structure 21.

[0058] The shaft portion 411 is mounted and fixed on the connecting portion 232. Specifically, the connecting assembly 40 includes a fastener 43. The connecting portion 232 is provided with a first connecting hole 232a. The shaft portion 411 is provided with a second connecting hole 412a, and the fastener 43 passes through the corresponding first connecting hole 232a and second connecting hole 412a, thereby fixing the shaft portion 411 on the connecting portion 232.

[0059] For example, the fastener 43 can be a combination screw, including a screw 431 and a washer 432. The first connecting hole 232a and the second connecting hole 412a can be correspondingly configured as screw holes. The connecting portion 232 is recessed and provided with a limiting groove, the first connecting hole 232a is located at the bottom of the limiting groove and communicates with the limiting groove. The washer 432 is disposed on the outer periphery of the screw 431. The washer 432 is accommodated in the limiting groove. The provision of the washer 432 increases the contact area between the screw 431 and the connecting portion 232, thereby improving the stability of the connection. In addition, the washer 432 can also effectively disperse the pressure of the screw 431 on the connecting portion 232, preventing the connecting portion 232 from deforming or being damaged due to excessive pressure.

[0060] Multiple washers 432 may be provided, and these washers may be identical or different. For example, in this embodiment, two washers 432 are provided, namely a flat washer 432a and an elastic washer 432b. The flat washer 432a is provided on the side closer to the connecting portion 232 to increase the contact area between the fastener 43 and the connecting portion 232. The elastic washer is provided on the side away from the connecting portion 232 to compensate for the gap between the screw 431 and the connecting portion 232.

[0061] It should be noted that multiple first connecting holes 232a may be provided. Correspondingly, the number of second connecting holes 412a and fasteners 43 is set in equal numbers to the number of first connecting holes 232a. For example, in this embodiment, two first connecting holes 232a are provided at intervals on the shaft portion 411.

[0062] See Figure 6 and Figure 7 In some embodiments of this application, the connecting shaft 41 includes a limiting post 412, which protrudes from the shaft body portion 411 on the side near the connecting portion 232. The connecting portion 232 has a limiting hole 232b. The limiting post 412 is accommodated in the limiting hole 232b. The limiting post 412 and the limiting hole 232b cooperate to effectively prevent misalignment between the connecting shaft 41 and the mounting structure, allowing the connecting shaft 41 to be pre-installed on the connecting structure 23, thereby facilitating the subsequent assembly of the fasteners 43.

[0063] In some embodiments, the end of the limiting post 412 has a frustum-shaped or tapered structure. This means that the cross-sectional area of ​​the end of the limiting post 412 gradually decreases from the shaft portion 411 towards the connecting portion 232. This arrangement facilitates the installation of the shaft portion 411 and allows the limiting post 412 to be interference-fitted into the limiting hole 232b, thus ensuring a secure installation of the limiting post 412 within the limiting hole 232b and improving the connection strength between the connecting shaft 41 and the mounting shaft.

[0064] It should be noted that during the long-term rotation of the display screen 30, which causes the connector 42 connected to the display screen 30 to rotate frequently, the fastener 43 may become loose. Therefore, the setting of the limiting post 412 and the limiting hole 232b ensures that even if the fastener 43 becomes loose, the connection reliability between the connecting shaft 41 and the connecting structure 23 can be maintained, which is beneficial to the stability of the display screen 30.

[0065] Preferably, the end of the fastener 43 passes through the connecting portion 232 toward the connecting shaft 41. That is, the fastener 43 connects the connecting portion 232 and the shaft portion 411 from the side of the connecting portion 232 away from the control panel 10 toward the opposite side. The side of the connecting portion 232 away from the control panel 10 has more operating space than the side closer to the shaft portion 411, thus facilitating the user's installation and removal of the display screen 30.

[0066] It should be noted that multiple limiting posts 412 can be provided. The number of limiting holes 232b can be one or the same as the number of limiting posts 412. Specifically, in this embodiment, two limiting posts 412 are housed in the same limiting hole 232b. The use of only one limiting hole 232b helps reduce processing difficulty and save processing costs.

[0067] For example, the surface of the connecting part 232 near the control panel 10 is a flat surface. The shaft part 411 abuts against the flat surface of the connecting part 232, and the abutting surface is also a flat surface, thereby ensuring a tight connection between the shaft part 411 and the connecting part 232 and improving the connection reliability between the connecting shaft 41 and the connecting part 232.

[0068] It should be noted that there is a gap between the bottom of the display screen 30 and the surface of the control panel 10 to prevent the control panel 10 from interfering with the rotation of the display screen 30. At the same time, without interfering with the rotation of the display screen 30, the distance between the axis of the connecting shaft 41 and the surface of the control panel 10 can be minimized, thus reducing the gap between the bottom of the display screen 30 and the surface of the control panel 10. This prevents the display screen 30 from being too high above the surface of the control panel 10, which would cause inconvenience for the operator when switching between the control panel 10 and the display screen 30.

[0069] In some embodiments, the axis of the shaft portion 411 is parallel to the surface of the control panel 10, thereby further reducing the distance between the axis of the connecting shaft 41 and the surface of the control panel 10 without interfering with the rotation of the display screen 30.

[0070] See Figure 5 and Figure 6In some embodiments of this application, the connecting structure 23 has a mounting groove 233 on the side opposite to the control panel 10. The support 20 includes a sealing structure 24, which is installed in the mounting groove 233. The sealing structure 24 is used to seal the end of the fastener 43 and the first connecting hole 232a on the connecting part 232, to prevent the accumulation of dust and other impurities, and at the same time improve the overall aesthetics of the support 20.

[0071] Specifically, the sealing structure 24 includes a sealing plate 241 and a protrusion 242 protruding from the sealing plate 241. The sealing plate 241 is accommodated in the mounting groove 233. The protrusion 242 is interference-fitted with the first connecting hole 232a on the connecting portion 232, thereby stably mounting the sealing structure 24 onto the connecting portion 232.

[0072] For example, the side surface of the sealing plate 241 facing away from the protrusion 242 is flush with the surface of the connecting structure 23 to ensure the overall aesthetics of the support 20 and facilitate the cleaning and maintenance of the support 20.

[0073] In some embodiments, the sealing structure 24 includes an anti-detachment portion 243, which protrudes from the sealing plate 241. The connecting portion 232 has a receiving opening 232c that mates with the anti-detachment portion 243. The end of the anti-detachment portion 243 is tapered or frustum-shaped. The tapered or frustum-shaped structure passes through the receiving opening 232c and abuts against the connecting portion 232. The anti-detachment portion 243 effectively prevents the sealing structure 24 from falling off, ensuring that the sealing structure 24 is securely installed on the connecting portion 232.

[0074] The sealing structure 24 can be made of elastic materials, such as rubber or silicone, and the quick assembly and disassembly of the sealing structure 24 can be achieved by utilizing the property that elastic materials can deform and reset.

[0075] The specific steps for mounting the display screen 30 on the support 20 in this application are as follows: the connecting shaft 41 connected to the display screen 30 is placed on the support part 231 in the connecting structure 23, and the connecting shaft 41 is pre-installed on the connecting structure 23 through the limiting post 412 and the limiting hole 232b; the display screen 30 is rotated to expose the first connecting hole 232a on the connecting structure 23; the connecting part 232 and the connecting shaft 41 are connected and fixed using fasteners 43; finally, the sealing structure 24 is installed on the connecting structure 23.

[0076] The specific steps for removing the display screen 30 from the support 20 are as follows: rotate the display screen 30 to expose the sealing structure 24; remove the sealing structure 24 from the connecting structure 23 to expose the fastener 43; remove the fastener 43 to separate the display screen 30 from the support 20.

[0077] In some embodiments, the connecting structure 23 is provided with cable passages 234 extending through both ends, which are used for the cable connecting the display screen 30. Specifically, the cable passages 234 are located on the support portion 231 in the connecting structure 23. It should be noted that the display screen 30 and the control panel 10 are usually connected by cables. Therefore, the cable passages 234 in the connecting structure 23 facilitate the cable passage. Combined with the inclined arrangement of the main body 211 in the fixing structure 21, the visible area of ​​the cables is increased, making it easier for users to organize and manage the cables.

[0078] Furthermore, the support part 231 is provided with a notch 232, which is connected to the cable passage 234, further facilitating the cable to pass through and connect the display screen 30 and the control panel 10.

[0079] In some embodiments, the surface of the connecting structure 23 facing away from the control panel 10 is an inclined surface 235, with one end of the inclined surface 235 tilting away from the control panel 10. This arrangement effectively enhances the strength of the connecting structure 23 while ensuring that it does not interfere with the rotation range of the display screen 30.

[0080] See Figure 6 The connecting structure 23 has clearance grooves 236 on both sides along the axial direction of the connecting shaft 41. The connecting shaft 41 includes a base portion 413 connected to the shaft body portion 411. The diameter of the base portion 413 is larger than the diameter of the shaft body portion 411. There are two base portions 413, which are correspondingly disposed in the two clearance grooves 236.

[0081] The connector 42 connecting the display screen 30 includes a rotating plate 421 rotatably mounted on the connecting shaft 41. The rotating plate 421 is located on the side of the base portion 413 away from the other base portion 413.

[0082] The connecting assembly 40 includes a lock nut 44 and a damping element 45. The lock nut 44 is connected to the end of the shaft portion 411. The damping element 45 and the rotating plate 421 are both disposed between the lock nut 44 and the base portion 413. The lock nut 44 is used to fix the damping element 45 and the connecting plate disposed on the connecting shaft 41. In addition, the lock nut 44, in conjunction with the damping element 45, adjusts the damping value to ensure that the display screen 30 can rotate smoothly while ensuring that the display screen 30 can be suspended stably without shaking.

[0083] Multiple damping elements 45 may be provided. The damping element 45 may be a disc spring, a washer 432, a spring, etc. Alternatively, multiple damping elements may include combinations of disc springs and washers 432, combinations of springs and washers 432, etc. The illustrations in this application use a disc spring for illustration.

[0084] Multiple disc springs are provided between the anti-loosening nut 44 and the rotating plate 421. It should be noted that the greater the compression of the disc springs, the greater the damping value, and the greater the force required to rotate the rotating plate 421. Furthermore, the compression of the disc springs can be adjusted by adjusting the distance between the anti-loosening nut 44 and the rotating component; alternatively, the compression of the disc springs can also be adjusted by increasing or decreasing the number of disc springs while keeping the distance between the anti-loosening nut and the rotating component constant. This setup is low-cost and simple to manufacture.

[0085] Please see Figure 6 and Figure 7 The connecting assembly 40 includes a limiting washer 46. The limiting washer 46 is sleeved on the shaft portion 411. The limiting washer 46 is arranged between the rotating plate 421 and the base portion 413. Multiple limiting washers 46 may be provided. The internal through hole of the limiting washer 46 is an irregular hole. The inner wall of the limiting washer 46 abuts against the surface of the shaft portion 411, so that the limiting washer 46 can be fixed on the connecting shaft 41 and will not rotate relative to the connecting shaft 41 as the rotating plate 421 rotates.

[0086] The limiting washer 46 has a limiting opening 461. The limiting opening 461 extends circumferentially along the limiting washer 46. The rotating plate 421 has a limiting protrusion 421a. The limiting protrusion 421a moves within the limiting opening 461, following the rotation of the rotating plate 421. By cooperating with the limiting opening 461 and the limiting protrusion 421a, the rotatable range of the rotating plate 421 can be set as needed, thereby limiting the rotatable range of the display screen 30, for example, limiting the rotatable range of the display screen 30 to within 30 degrees, within 35 degrees, within 40 degrees, etc.

[0087] The description focuses on limiting the rotation range of the display screen 30 to within 30 degrees. The angle formed between the display screen 30 and the horizontal plane can be from 30 degrees to 60 degrees, or from 40 degrees to 70 degrees, etc.

[0088] In addition, it should be noted that the setting of the limiting washer 46 also keeps the rotating plate 421 away from the outer wall of the support 20 along the axis of the connecting shaft 41, effectively preventing the support 20 from interfering with the rotation of the display screen 30.

[0089] For example, the number of limiting washers 46 on both ends of the shaft portion 411 is the same along the axial direction of the connecting shaft 41, so as to ensure that the gaps between the two connecting parts 42 of the display screen 30 and the side wall of the support 20 are equal, which is conducive to the smooth rotation of the display screen 30.

[0090] The connector 42 includes an assembly plate 422 connected to one end of the rotating plate 421. The assembly plate 422 is bent to connect to the rotating plate 421, and the assembly plate 422 is used to connect the display screen 30. In this example, the assembly plate 422 can be detachably connected to the display screen 30 by a connecting structure 23 such as screws 431 or pins.

[0091] This application, by setting a support 20, positions the display screen 30 outside the control panel 10, making the display screen 30 and control panel 10 independent of each other. This facilitates operation, effectively reduces the complexity of disassembling and assembling the display screen 30, and improves disassembly, assembly, and maintenance efficiency. Furthermore, the display screen 30 is rotatably connected to the connection structure 23 of the support 20, allowing users to easily adjust the angle and position of the display screen 30. This facilitates cleaning the space between the bottom of the display screen 30 and the surface of the control panel 10, including the connection structure 23 of the support 20 located outside the control panel 10 and the connection point between the display screen 30 and the support 20. It is understood that this application eliminates the space between the control panel 10 and the display screen 30 required for smooth rotation when the display screen 30 and control panel 10 are designed with a recessed shape in the prior art. This effectively solves the problem that dust and other impurities can easily enter the interior of the control panel 10 through the space, making cleaning difficult.
