[0035] The embodiment of the present invention provides an ultrasonic anti-infection uniform coating device, such as Figure 1-13 As shown, the ultrasonic infection prevention uniform coating device comprises: an equipment housing 1, the bottom of which is open; a coupling agent storage box 2, which is arranged in the equipment housing 1 and has an opening at the top; hanging plates 3 are fixedly installed on opposite sides of the coupling agent storage box 2; a pair of electric telescopic rods 4 are fixedly installed on the top inner wall of the equipment housing 1, and the output rods of the pair of electric telescopic rods 4 are respectively fixedly connected to the tops of the two hanging plates 3; a U-shaped roller frame 5, which is fixedly installed at the bottom of the coupling agent storage box 2; a coupling agent application roller 6, which is rotatably installed on the top inner wall of the equipment housing 1; and a coupling agent application roller 6, which is rotatably installed on the top inner wall of the equipment housing 1. On the U-shaped roller frame 5; two groups of disinfection lamps 7 are respectively fixedly installed on the inner walls on both sides of the equipment housing 1, and respectively correspond to the openings on both sides of the U-shaped roller frame 5, and are used to disinfect the coupling agent coating roller 6 and the inside of the equipment housing 1; a long strip through port 8 is opened at the top of the coupling agent storage box 2, and a plurality of coupling agent discharge pipes 9 fixedly connected to the bottom of the coupling agent storage box 2 are arranged in the long strip through port 8, and the plurality of coupling agent discharge pipes 9 are all connected to the coupling agent storage box 2, and are used to discharge the coupling agent and drop it onto the coupling agent coating roller 6.

[0036] In this embodiment, the device mainly includes an equipment housing 1, a coupling agent storage box 2, a lifting plate 3, an electric telescopic rod 4, a U-shaped roller frame 5, a coupling agent application roller 6, a disinfection lamp 7 and a long strip through port 8, etc.

[0037] The bottom of the equipment housing 1 is open to facilitate the lifting and lowering of the coupling agent storage box 2, the U-shaped roller frame 5 and the coupling agent application roller 6, so that the coupling agent application roller 6 can be extended to contact the part to be inspected to apply the coupling agent. The coupling agent storage box 2 is arranged in the equipment housing 1, and its top is open to store the coupling agent. The coupling agent storage box 2 is fixedly installed with hanging plates 3 on the opposite sides of the coupling agent storage box 2, and the output rods of the electric telescopic rod 4 are respectively fixedly connected to the tops of the two hanging plates 3, which are used to control the lifting and lowering of the coupling agent storage box 2, the U-shaped roller frame 5 and the coupling agent application roller 6, and then adjust the height of the coupling agent application roller 6.

[0038] The U-shaped roller frame 5 is fixedly mounted at the bottom of the coupling agent storage box 2, and the coupling agent application roller 6 is rotatably mounted on the U-shaped roller frame 5 for applying the coupling agent. Two groups of disinfection lamps 7 are respectively fixedly mounted on the inner walls of the device housing 1 on both sides, corresponding to the openings on both sides of the U-shaped roller frame 5, and are used to disinfect the coupling agent application roller 6 and the inside of the device housing 1 to prevent cross infection.

[0039] The long strip through opening 8 is opened at the top of the coupling agent storage box 2, and a plurality of coupling agent discharge pipes 9 are provided inside the coupling agent storage box 2 and fixedly connected to the bottom of the coupling agent storage box 2. These coupling agent discharge pipes 9 are all connected to the coupling agent storage box 2, and are used to discharge the coupling agent and drop it onto the coupling agent application roller 6, so as to ensure that the coupling agent application roller 6 can evenly apply the coupling agent.

[0040] When using the device, firstly adjust the height of the coupling agent storage box 2 by the electric telescopic rod 4 so that the coupling agent application roller 6 extends out of the device housing 1, and then hold the device to make the coupling agent application roller 6 contact the part to be inspected.

[0041] Then, the coupling agent is discharged through the coupling agent discharge pipe 9 and falls on the coupling agent application roller 6. At this time, the device is manually moved to make the coupling agent application roller 6 roll along the body surface, and the coupling agent is evenly applied to the part to be inspected by the coupling agent application roller 6. Before and after each use, the parts are reset and the coupling agent application roller 6 is put into the device housing 1. The coupling agent application roller 6 and the inside of the device housing 1 can be disinfected by the disinfection lamp 7 to prevent cross infection.

[0042] The beneficial effects of the present invention are as follows: first, the overall size is small, people can operate it by hand, and the height of the coupling agent application roller 6 can be adjusted by the electric telescopic rod 4. It can be extended when application is needed and retracted for protection when not needed; the coupling agent application roller 6 and the inside of the device housing 1 are disinfected by the disinfection lamp 7, which effectively reduces the risk of infection; the coupling agent application roller 6 can evenly apply the coupling agent, thereby improving the efficiency and quality of ultrasonic examination.

[0043] In a further preferred embodiment of the present invention, a coupling agent scraping mechanism is provided on the U-shaped roller frame 5, and the coupling agent scraping mechanism includes a bidirectional screw 10 arranged above the coupling agent smear roller 6, and the bidirectional screw 10 can be adjusted up and down along the U-shaped roller frame 5. Cleaning scrapers 11 are installed on the two sections of the threaded rods of the bidirectional screw 10 in a threaded drive manner. Both of the cleaning scrapers 11 can be driven by the bidirectional screw 10 to slide along the surface of the coupling agent smear roller 6 to clean the residual coupling agent on the coupling agent smear roller 6. Both of the cleaning scrapers 11 can be driven by the bidirectional screw 10 to adjust up and down to control the separation or engagement of the cleaning scraper 11 and the coupling agent smear roller 6.

[0044] In this embodiment, the device adds a coupling agent scraping mechanism on the original basis, so that the device can more effectively clean the residual coupling agent on the coating roller after applying the coupling agent, thereby improving the cleanliness and reusability of the device.

[0045] The coupling agent scraping mechanism mainly includes a bidirectional screw 10 and a cleaning scraper 11. The bidirectional screw 10 is arranged on the U-shaped roller frame 5 and can be adjusted up and down along the U-shaped roller frame 5. The cleaning scrapers 11 are installed on the two threaded rods of the bidirectional screw 10 in a threaded driving manner. The two cleaning scrapers 11 can be driven by the bidirectional screw 10 to slide along the surface of the coupling agent application roller 6 to clean the coupling agent remaining on the coupling agent application roller 6.

[0046] When in use, first adjust the height of the coupling agent storage box 2 through the electric telescopic rod 4, so that the coupling agent application roller 6 extends out of the device housing 1 and contacts the part to be examined. At this time, the cleaning scraper 11 is separated from the coupling agent application roller 6 to avoid affecting the application of the coupling agent. Subsequently, the coupling agent is discharged through the coupling agent discharge pipe 9 and falls on the coupling agent application roller 6. The medical staff manually moves the device to make the coupling agent application roller 6 roll along the body surface and evenly apply the coupling agent to the part to be examined.

[0047] After the coupling agent is applied, all parts are reset, and the coupling agent application roller 6 is retracted into the device housing 1 and meshed with the cleaning scraper 11. At this time, the medical staff can adjust the bidirectional screw 10 to make the two cleaning scrapers 11 slide along the surface of the coupling agent application roller 6, thereby cleaning the coupling agent remaining on the application roller. The coupling agent application roller 6 can also be rotated during cleaning to ensure the scraping effect. The upper and lower positions of the cleaning scraper 11 can also be adjusted by the bidirectional screw 10 to control the separation or meshing of the cleaning scraper 11 and the coupling agent application roller 6, so that the cleaning scraper 11 can be conveniently prevented from being worn due to long-term contact with the coupling agent application roller 6 when not in use. Specifically, it is separated when applying the coupling agent and meshed when cleaning.

[0048] Before and after each use, medical staff can also reset the components so that the cleaning scraper 11 cleans the surface of the coupling agent application roller 6, and then use the disinfection lamp 7 to disinfect the coupling agent application roller 6, the cleaning scraper 11 and the inside of the device housing 1 to ensure cleanliness and safety during the next use.

[0049] The present invention adds a coupling agent scraping mechanism, and the cleaning scraper 11 can be adjusted in position by the bidirectional screw 10, which can effectively clean the residual coupling agent on the coupling agent application roller 6. At the same time, when applying the coupling agent, it avoids wear caused by long-term contact, thereby improving the cleanliness and reusability of the device.

[0050] The arrangement of the electric telescopic rod 4 and the disinfection lamp 7 enables the device to flexibly adjust the height and perform disinfection, thereby improving the convenience and safety of use.

[0051] The overall size of the device is small, which makes it convenient for medical staff to operate it by hand, reducing their workload.

[0052] In a further preferred embodiment of the present invention, a long strip guide slide 12 is provided on each of the two cleaning scrapers 11, and a rectangular guide rod 13 is fixedly installed in the U-shaped roller frame 5. The rectangular guide rod 13 slides through the corresponding long strip guide slides 12 on the two cleaning scrapers 11, and the rectangular guide rod 13 is arranged parallel to the bidirectional screw 10.

[0053] In this embodiment, the ultrasonic anti-infection coating device is added with a coupling agent scraping mechanism on the original basis, and the cleaning effect and operational stability of the device are significantly improved by introducing the design of the long guide slide 12 and the rectangular guide rod 13.

[0054] Applying coupling agent: First, adjust the height of the coupling agent storage box 2 through the electric telescopic rod 4 so that the coupling agent application roller 6 extends out of the device housing 1 and contacts the part to be examined. At this time, the cleaning scraper 11 is kept separated from the coupling agent application roller 6 to avoid affecting the application of the coupling agent. Subsequently, the coupling agent is discharged through the coupling agent discharge pipe 9 and falls on the coupling agent application roller 6. The medical staff manually moves the device to make the coupling agent application roller 6 roll along the body surface and evenly apply the coupling agent to the part to be examined.

[0055] Cleaning the coupling agent: After the coupling agent is applied, the medical staff retracts the coupling agent application roller 6 into the device housing 1, and the cleaning scraper 11 engages with the coupling agent application roller 6. At this time, by adjusting the bidirectional screw 10, the two cleaning scrapers 11 slide along the surface of the coupling agent application roller 6, and the residual coupling agent on the application roller is stably cleaned by the guiding effect of the long strip guide slide 12 and the rectangular guide rod 13. During the cleaning process, the coupling agent application roller 6 can also be rotated appropriately to ensure a more thorough scraping effect.

[0056] When the cleaning scraper 11 is raised or lowered, the long strip guide slide 12 thereon can ensure that it is raised or lowered along the rectangular guide rod 13, thereby avoiding lifting or lowering jams.

[0057] Disinfection: After cleaning, medical staff can use the disinfection lamp 7 inside the device to disinfect the coupling agent application roller 6, the cleaning scraper 11 and the inside of the device housing 1 to ensure cleanliness and safety during the next use.

[0058] In this embodiment, the design of the coupling agent scraping mechanism utilizes the rotation drive of the bidirectional screw 10 and the long strip guide slides 12 on the two cleaning scrapers 11. When the bidirectional screw 10 rotates, the cleaning scrapers 11 are driven to slide along the surface of the coupling agent coating roller 6. At the same time, the rectangular guide rod 13 slides through the long strip guide slides 12 on the cleaning scrapers 11, providing a stable guide and support function for the cleaning scrapers 11, ensuring the stability and linearity of the cleaning process.

[0059] In a further preferred embodiment of the present invention, support shaft plates 14 are provided on both sides of the U-shaped roller frame 5 relative to the two ends of the coupling agent coating roller 6, and lifting slides 15 are provided on the two support shaft plates 14. Anti-slip positioning blocks 16 can be slidably installed on the two support shaft plates 14, and the anti-slip positioning blocks 16 can be slidably penetrated through the corresponding lifting slides 15 and fixedly connected to the corresponding sides of the U-shaped roller frame 5. The bottom inner walls of the two lifting slides 15 and the bottoms of the corresponding anti-slip positioning blocks 16 are fixedly installed with the same return spring 17, and the corresponding inner walls on both sides of the equipment housing 1 are fixedly installed with resistance blocks 18, and the two resistance blocks 18 can be pressed on the tops of the two support shaft plates 14 respectively, and avoidance openings 19 are provided on both sides of the U-shaped roller frame 5 corresponding to the two support shaft plates 14, and support shafts 20 can be rotatably installed on the two support shaft plates 14, and the two support shafts 20 can respectively movably penetrate through the two avoidance openings 19 and are respectively fixedly connected to the two ends of the bidirectional screw 10.

[0060] In this embodiment, when the device is not used to apply the coupling agent, the status of each component is as shown in the figure. When the coupling agent needs to be applied, the electric telescopic rod 4 is started, so that the hoisting plate 3 drives the coupling agent storage box 2, the U-shaped roller frame 5 and the coupling agent application roller 6 to descend. During the descent, since the position of the abutment block 18 does not move, the support shaft plate 14 is slidably arranged on the side of the U-shaped roller frame 5 using the anti-slip positioning block 16, and is elastically supported by the return spring 17. At this time, the return spring 17 is in a tensioned state. At this time, due to the gradual weakening of the pressing force from above, the top of the support shaft plate 14 is always tightly attached to the bottom of the abutment block 18, and the return spring 17 retracts, so that the support shaft plate 14 slides up along the anti-slip positioning block 16, driving the support shaft 20 to slide up along the avoidance opening 19. At this time, the distance between the bidirectional screw 10 and the coupling agent application roller 6 is increased, and the cleaning scraper 11 is separated from the coupling agent application roller 6;

[0061] After the application is completed, the output rod of the electric telescopic rod 4 retracts to reset the components. Under the resistance of the resistance block 18 to the support shaft plate 14, the support shaft plate 14 slides down along the anti-slip positioning block 16 and stretches the reset spring 17, so that the cleaning scraper 11 and the coupling agent application roller 6 are re-engaged to facilitate the cleaning of the coupling agent.

[0062] In a further preferred embodiment of the present invention, a driving wheel 21 and a driven wheel 23 are fixedly installed at both ends of the two support shafts 20, and a driven wheel 22 is fixedly installed at one end of the coupling agent coating roller 6 corresponding to the driving wheel 21, and the driven wheel 22 can be engaged with or separated from the driving wheel 21. A motor housing 24 is fixedly installed on one side of the device housing 1 corresponding to the driven wheel 23, and a driving motor 25 is fixedly installed in the motor housing 24. The output shaft of the driving motor 25 can be rotatably extended into the device housing 1 and fixedly installed with a driving wheel 26, and the driving wheel 26 can be engaged with or separated from the driven wheel 23.

[0063] In this embodiment, a driving wheel 1 21 and a driven wheel 2 23 are fixedly mounted at both ends of the two support shafts 20, and a driven wheel 1 22 is fixedly mounted at one end of the coupling agent smearing roller 6 corresponding to the driving wheel 1 21. This design allows the rotation of the coupling agent smearing roller 6 to be controlled by adjusting the meshing state between the driving wheel 1 21 and the driven wheel 1 22. When the coupling agent on the coupling agent smearing roller 6 needs to be cleaned, the driving wheel 1 21 meshes with the driven wheel 1 22, thereby driving the coupling agent smearing roller 6 to rotate, thereby realizing the synchronous movement of the movement of the cleaning scraper 11 and the cleaning of the coupling agent.

[0064] In addition, a motor housing 24 is fixedly installed on one side of the device housing 1 corresponding to the driven wheel 23, and a driving motor 25 is fixedly installed in the motor housing 24. The output shaft of the driving motor 25 can be rotatably extended into the device housing 1 and fixedly installed with a driving wheel 26, which can be engaged or disengaged with the driven wheel 23. This design allows the rotation of the support shaft 20, the bidirectional screw 10 and the coupling agent application roller 6 to be controlled by adjusting the meshing state between the driving wheel 26 and the driven wheel 23.

[0065] When applying the coupling agent, the driving wheel 1 21 and the driven wheel 1 22 are separated, and the driving wheel 2 26 can be separated from the driven wheel 2 23. At this time, the rotation of the coupling agent application roller 6 is manually controlled without affecting other components.

[0066] When cleaning the coupling agent on the coupling agent coating roller 6, the driving wheel 1 21 and the driven wheel 1 22 are meshed, the driving wheel 2 26 can be meshed with the driven wheel 2 23, and the driving motor 25 is started to make the driving wheel 2 26 drive the meshed driven wheel 2 23 to rotate, so that the support shaft 20 drives the bidirectional screw 10 to rotate, and the synchronous driving wheel 1 21 drives the driven wheel 1 22 to rotate, so that the coupling agent coating roller 6 rotates synchronously. During cleaning, the reciprocating forward and reverse rotation of the driving motor 25 can be controlled to control the back and forth scraping of the cleaning scraper 11 and the reciprocating rotation of the coupling agent coating roller 6.

[0067] The two ends of the two support shafts 20 are respectively fixedly mounted with a driving wheel 1 21 and a driven wheel 2 23, and the coupling agent coating roller 6 is fixedly mounted with a driven wheel 1 22 at one end corresponding to the driving wheel 1 21. This design allows the rotation of the coupling agent coating roller 6 to be controlled by adjusting the meshing state between the driving wheel 1 21 and the driven wheel 1 22.

[0068] This design makes the rotation and cleaning process of the coupling agent coating roller 6 more automated and efficient. By adjusting the meshing state between the driving wheel 1 21, the driven wheel 1 22, the driving wheel 2 26 and the driven wheel 2 23, the coating and cleaning modes can be conveniently switched, thereby improving the working efficiency and cleaning effect. At the same time, this design also increases the flexibility and reliability of the device, and is suitable for various scenarios where coupling agent needs to be applied.

[0069] In a further preferred embodiment of the present invention, the outer edge of the coupling agent application roller 6 extends to the outside of the bottom of the U-shaped roller frame 5, and the two cleaning scrapers 11 have a notch for the coupling agent application roller 6 to be inserted into.

[0070] In this embodiment, the outer edge of the coupling agent smearing roller 6 is designed to extend beyond the bottom of the U-shaped roller frame 5. This design enables the coupling agent smearing roller 6 to contact and smear the target surface more directly. At the same time, both cleaning scrapers 11 have notches for the coupling agent smearing roller 6 to fit into. This structure enables the cleaning scrapers 11 to fit closely to the surface of the coupling agent smearing roller 6 during the cleaning process, thereby scraping off the residual coupling agent more effectively.

[0071] In a further preferred embodiment of the present invention, the cross section of the anti-drop positioning block 16 is an I-shaped shape, the width of both ends of the anti-drop positioning block 16 is greater than the width of the lifting slide 15 , and the two ends are respectively buckled on both sides of the support shaft plate 14 .

[0072] In this embodiment, the "I"-shaped design of the anti-slipping positioning block 16 can prevent the lifting assembly from slipping out of the lifting slide 15 when the two ends of the anti-slipping positioning block 16 are buckled on the two sides of the support shaft plate 14. At the same time, due to the close fit between the anti-slipping positioning block 16 and the support shaft plate 14, the shaking of the lifting assembly during movement can be reduced to a certain extent, thereby improving stability.

[0073] In a further preferred embodiment of the present invention, the opening widths of the two avoidance openings 19 are both greater than the diameter of the support shaft 20, the inner sides of the driving wheel 1 21 and the driven wheel 2 23 are staggered with the outer sides of the corresponding upper anti-slip positioning blocks 16, the driving wheel 1 21 is located above the driven wheel 1 22, and the driving wheel 2 26 is located above the driven wheel 2 23.

[0074] In this embodiment, the opening widths of the two avoidance openings 19 are both larger than the diameter of the support shaft 20 . Such a design allows the support shaft 20 to smoothly pass through the avoidance openings 19 without being obstructed during the lifting process.

[0075] In addition, the inner sides of the driving wheel 1 21 and the driven wheel 2 23 are staggered with the outer sides of the corresponding upper anti-slip positioning block 16. This design ensures that when the driving wheel or the driven wheel rotates, they will not interfere with the anti-slip positioning block 16, thereby ensuring the smooth operation of the lifting assembly.

[0076] In the layout of the wheel train, the driving wheel 1 21 is located above the driven wheel 1 22, and the driving wheel 2 26 is located above the driven wheel 2 23. This layout enables the driving wheel to drive the driven wheel more effectively, and also helps to maintain the stability of the entire lifting system.

[0077] In a further preferred embodiment of the present invention, a controller 27 is fixedly installed on the outer side of the device housing 1 , and the controller 27 is connected to both the electric telescopic rod 4 and the driving motor 25 .

[0078] In this embodiment, the controller 27, as the core control unit of the entire lifting system, realizes centralized control of the entire system through connection with the electric telescopic rod 4 and the drive motor 25. The controller 27 integrates advanced control algorithms and logic circuits, and can dynamically adjust the telescopic length of the electric telescopic rod 4 and the current, voltage, and speed of the drive motor 25 according to the user's needs and the real-time status of the lifting component. Through precise control algorithms and real-time feedback mechanisms, it is ensured that the lifting component can be lifted and lowered according to the predetermined trajectory and speed, thereby improving the stability and accuracy of the system.

[0079] The user can control the electric telescopic rod 4 and the drive motor 25 at the same time by operating the controller 27. After receiving the user's command, the controller 27 will send a signal to the electric telescopic rod 4 to control its telescopic length, thereby adjusting the initial position of the lifting component or making fine adjustments. At the same time, the controller 27 will also send a command to the drive motor 25 to control its rotation direction and speed, thereby driving the lifting component to perform lifting and lowering movements.

[0080] In a further preferred embodiment of the present invention, a main cover 28 is detachably mounted on the top of the device housing 1 , and the main cover 28 is disposed at a position corresponding to the positioning opening of the coupling agent storage box 2 .

[0081] In this embodiment, when the coupling agent needs to be added or replaced, the user can remove the main cover 28 from the top of the device housing 1 through simple operations.

[0082] Once the main cover 28 is removed, the user can clearly see and access the coupling agent storage box 2. By positioning the opening, the user can easily take out or put in the coupling agent to ensure the normal operation of the device.

[0083] After adding or replacing the coupling agent, the user only needs to reinstall the main cover 28 on the top of the device housing 1 and fix it with the corresponding locking mechanism or screws.

[0084] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments:

[0085] In another embodiment of the present invention, an outer handle 29 is fixedly installed on the top of the device housing 1, and an inner handle 30 is slidably installed in the outer handle 29. A trigger switch 31 is fixedly installed on the top inner wall of the outer handle 29, which can be triggered by the inner handle 30. Stable guide grooves 32 are provided on the inner walls on both sides of the outer handle 29, and stable guide blocks 33 can be slidably installed in the two stable guide grooves 32. The two stable guide blocks 33 are respectively fixedly connected to the two sides of the inner handle 30, and a reset spring 2 34 is fixedly installed between the top inner walls of the two stable guide grooves 32 and the tops of the two stable guide blocks 33. The coupling agent storage box 2 is provided with a coupling agent pushing mechanism.

[0086] In this embodiment, the top of the device housing 1 is designed with an innovative outer handle 29 structure, which is intended to improve the user's handheld operation. An inner handle 30 is slidably installed inside the outer handle 29, allowing the user to adjust the position of the inner handle 30 as needed. A trigger switch 31 is fixedly installed on the inner wall of the top of the outer handle 29, which can be abutted and triggered by the inner handle 30 when it is in a specific position, thereby controlling the amount of coupling agent discharged.

[0087] In order to ensure the stability of the inner handle 30 during the sliding process, a stabilizing guide groove 32 is provided on the inner walls of both sides of the outer handle 29. Stabilizing guide blocks 33 are slidably installed in the two stabilizing guide grooves 32, respectively, and the two stabilizing guide blocks 33 are fixedly connected to both sides of the inner handle 30. This design enables the inner handle 30 to move along the track of the stabilizing guide groove 32 during the sliding process, effectively preventing deviation or shaking.

[0088] In addition, two return springs 34 are fixedly installed between the top inner walls of the two stable guide grooves 32 and the tops of the two stable guide blocks 33. These return springs 34 can automatically return the inner handle 30 to the initial position when the inner handle 30 is not subjected to external force, thereby ensuring the ease of use and continuity of operation of the device.

[0089] It is worth mentioning that the device is also equipped with a coupling agent storage box 2, and on this basis, a coupling agent pushing mechanism is provided, which cooperates with the use of a trigger switch 31 to facilitate the control of the discharge amount and timing of the coupling agent.

[0090] In another embodiment of the present invention, the coupling agent pushing mechanism includes a piston plate 35 slidably installed in the coupling agent storage box 2, a lifting screw 36 is rotatably installed in the coupling agent storage box 2, and the lifting screw 36 threadedly penetrates the piston plate 35, a motor 37 is fixedly installed on the outside of the coupling agent storage box 2, and the motor 37 is connected to the trigger switch 31, and the output shaft of the motor 37 and the top end of the lifting screw 36 are fixedly installed with a pulley 38, and the two pulleys 38 are provided with the same synchronous belt 39.

[0091] In this embodiment, the design of the coupling agent pushing mechanism further enhances the practicality and convenience of the device. The mechanism mainly includes a piston plate 35 slidably mounted in the coupling agent storage box 2, and a lifting screw 36 rotatably mounted in the coupling agent storage box 2. The lifting screw 36 penetrates the piston plate 35 through a thread, and when the lifting screw 36 rotates, the piston plate 35 moves up and down according to the direction of the thread.

[0092] In order to drive the rotation of the lifting screw 36, the present invention fixes a motor 37 on the outside of the coupling agent storage box 2. The motor 37 is connected to the trigger switch 31 in the outer handle 29 described above. When the user triggers the switch 31 by operating the inner handle 30, the motor 37 receives the start signal and starts working.

[0093] In order to transmit the rotational power of the motor 37 to the lifting screw 36, the present invention installs pulleys 38 on both components and connects them with the same synchronous belt 39. In this way, when the motor 37 rotates, the pulley 38 on its output shaft will also rotate, and drive the pulley 38 at the top of the lifting screw 36 to rotate synchronously through the synchronous belt 39, thereby realizing the rotation of the lifting screw 36.

[0094] When in use, the user only needs to hold the outer handle 29 and slide the inner handle 30 to trigger the switch 31, and the motor 37 will start and drive the piston plate 35 to move up and down in the coupling agent storage box 2 through the lifting screw 36. When the piston plate 35 moves downward, it pushes the coupling agent in the coupling agent storage box 2 to flow out through the coupling agent discharge pipe 9 to the coupling agent application roller 6.

[0095] In another embodiment of the present invention, there may be multiple lifting screws 36. If there are multiple lifting screws 36, the bottom ends of the multiple lifting screws 36 extend into the long strip through-port 8, and the bottom ends of the multiple lifting screws 36 are fixedly sleeved with a pulley 2 40, and the same synchronous belt 2 41 is sleeved on the multiple pulleys 2 40.

[0096] In this embodiment, the number of lifting screws 36 is designed to be multiple to accommodate coupling agent storage boxes 2 of different sizes or shapes. When there are multiple lifting screws 36, the bottom ends of these screws will extend into a long strip through hole 8 to ensure that they can move synchronously.

[0097] In order to realize the synchronous rotation of multiple lifting screws 36, the present invention has a pulley 2 40 fixedly mounted on the bottom end of each lifting screw 36. The same synchronous belt 2 41 is mounted on the multiple pulleys 2 40 to form a synchronous transmission system. In this way, when the motor 37 is started, it will drive one of the lifting screws 36 to rotate through the pulley 1 38 and the synchronous belt 1 39. The rotation of this screw will be transmitted to all other screws through the synchronous belt 2 41 to ensure that they can work synchronously and coordinatedly.

[0098] This design brings significant advantages. First, multiple lifting screws 36 can push the piston plate 35 more evenly, avoiding the problem of the piston plate 35 tilting or getting stuck due to uneven force at a single point. Second, the synchronous transmission system ensures that the rotation speed and direction of all screws are consistent, further improving the accuracy and stability of pushing materials.

[0099] When in use, the user only needs to operate the outer handle 29 and the inner handle 30 as before to trigger the motor 37. After the motor 37 is started, the plurality of lifting screws 36 will rotate synchronously, pushing the piston plate 35 to move downward, thereby pushing the coupling agent out of the coupling agent storage box 2.

[0100] In addition, this design also enables the device to adapt to coupling agent storage boxes 2 of different sizes and shapes. It is only necessary to adjust the number and position of the lifting screws 36 according to the size and shape of the storage box to achieve a fast and accurate material pushing operation.

[0101] In summary, the present invention further improves the performance and reliability of the coupling agent pushing mechanism by adopting multiple lifting screws 36 and a synchronous transmission system. This design not only improves the accuracy and stability of pushing, but also makes the device more flexible and easy to adapt to different usage scenarios.

[0102] In another embodiment of the present invention, a secondary sealing cover 42 is installed on the piston plate 35 in a threaded manner, and the secondary sealing cover 42 is arranged at a corresponding position to the main sealing cover 28 .

[0103] In this embodiment, the secondary cover 42 is installed on the piston plate 35 in a threaded manner. This design allows the secondary cover 42 to fit tightly on the piston plate 35, thereby effectively preventing the coupling agent from leaking during storage.

[0104] The threaded mounting method of the auxiliary cover 42 also enables it to be easily disassembled and installed, and is convenient for adding coupling agent.

[0105] In another embodiment of the present invention, sealing plates 43 are slidably installed on both sides of the bottom of the device housing 1. The two sealing plates 43 are located below the coupling agent coating roller 6 when resetting and can be separated or closed from each other. Winding rollers 44 are rotatably installed on both sides of the device housing 1. Draw ropes 45 are wound on the two winding rollers 44. The free ends of multiple draw ropes 45 can be slidably extended into the device housing 1 and fixedly connected to the corresponding sealing plates 43. Fixed blocks 46 are fixedly installed on the two sealing plates 43. Multiple fixed blocks 46 are fixedly installed on the corresponding inner side walls of the device housing 1. A reset spring 47, a wire pressing roller 48 is rotatably installed in the device housing 1, and the wire pressing roller 48 is pressed onto the pull rope 45 on the corresponding side. A synchronization shaft 49 is rotatably installed on both sides of the device housing 1, and a circular gear 50 is fixedly installed on one end of the two synchronization shafts 49 located in the device housing 1, and a rack 51 is fixedly installed on the two hanging plates 3, and the two racks 51 are respectively meshed with the two circular gears 50, and a bevel gear 52 is fixedly sleeved on one end of the two synchronization shafts 49 located outside the device housing 1 and the two winding rollers 44, and the corresponding two bevel gears 52 are meshed.

[0106] In this embodiment, both sides of the bottom of the device housing 1 are designed with slidable sealing plates 43. The two sealing plates 43 are located below the coupling agent application roller 6 when resetting, and they can be separated or closed to meet different operating requirements. The design of the sealing plates 43 is to ensure that after the coupling agent is applied, when the internal components are stored, the application area can be kept closed to avoid leakage or contamination of the coupling agent.

[0107] In order to realize the sliding control of the sealing plate 43, winding rollers 44 are installed on both sides of the device housing 1, and a pull rope 45 is wound on each winding roller 44. The free end of the pull rope 45 extends into the interior of the device housing 1 and is fixedly connected to the corresponding sealing plate 43. When the pull rope 45 is wound or released, the sealing plate 43 will slide accordingly to realize the opening or closing action.

[0108] In order to keep the sealing plate 43 in a closed state when no external force is applied, a fixing block 46 is fixed to each sealing plate 43. A return spring 3 47 is installed between the fixing blocks 46 and the inner side wall of the device housing 1. When an external force acts on the sealing plate 43 to open it, the return spring 3 47 will be compressed; when the external force disappears, the return spring 3 47 will release the elastic force, so that the sealing plate 43 automatically returns to the closed state.

[0109] In addition, a pressing roller 48 is installed in the device housing 1, which is pressed on the pull rope 45 on the corresponding side. The function of the pressing roller 48 is to ensure that the pull rope 45 remains flat during movement to prevent it from bending or winding, thereby ensuring smooth sliding of the sealing plate 43.

[0110] In order to realize automatic control of the winding and releasing of the pull rope 45, a synchronous shaft 49 is also installed on both sides of the equipment housing 1. A circular gear 50 is fixed to one end of the synchronous shaft 49, and a rack 51 meshing with the circular gear 50 is fixed to the hanging plate 3. When the hanging plate 3 moves up and down, the rack 51 drives the circular gear 50 to rotate, thereby driving the synchronous shaft 49 to rotate.

[0111] The synchronous shaft 49 and the winding roller 44 are both fixedly sleeved with bevel gears 52, and the two corresponding bevel gears 52 are meshed. Therefore, when the synchronous shaft 49 rotates, the winding roller 44 is driven to rotate accordingly through the transmission of the bevel gear 52, thereby controlling the winding or release of the pull rope 45, and further realizing the opening or closing of the sealing plate 43.

[0112] In summary, compared with the related art, the overall size of the device is smaller, people can operate it by hand, and the height of the coupling agent application roller 6 can be adjusted by the electric telescopic rod 4. It can be extended when application is needed and retracted for protection when not needed. The coupling agent application roller 6 and the inside of the device housing 1 are disinfected by the disinfection lamp 7, which effectively reduces the risk of infection. The coupling agent application roller 6 can evenly apply the coupling agent, thereby improving the efficiency and quality of ultrasonic examination.
