[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides a digital signature comparison conflict warning device for laboratory testing software, including a frame 1, a support plate 2 fixedly connected to the left end of the front middle of the frame 1, a heat preservation mechanism 3 provided on the top of the support plate 2, the heat preservation mechanism 3 is used to keep the signature machine warm, a filter mechanism 4 is provided on the right side inside the heat preservation mechanism 3, the filter mechanism 4 is used to prevent air from entering, and a signature mechanism 5 is provided on the top of the support plate 2.

[0033] The heat preservation mechanism 3 includes a fixed frame 31, the bottom of which is fixedly connected to the top of the support plate 2. A cover plate 32 is rotatably connected to the top inner side of the fixed frame 31. A bracket 33 is fixedly connected to the top inner side of the cover plate 32. Multiple heating tubes 34 are fixedly connected inside the bracket 33. Air inlets 35 are provided on both the left and right sides of the fixed frame 31. Fans 36 are fixedly connected inside both air inlets 35. A rotating component 37 is provided on the rear inner side of the cover plate 32. A sealing component 38 is provided on the outer wall of the cover plate 32.

[0034] Specifically, the bottom of the fixed frame 31 is fixedly connected to the top of the support plate 2, providing a support base for the entire insulation mechanism 3. The top inner side of the fixed frame 31 is rotatably connected to the cover plate 32, which can rotate around the connection point to open or close the internal space of the fixed frame 31. The bracket 33 is fixedly connected to the top inner side of the cover plate 32, and multiple heating tubes 34 are fixedly connected inside it. When the signature machine needs to be kept warm, they generate heat by being powered on, raising the temperature of the internal space of the fixed frame 31. The air inlets 35 are opened on the left and right sides of the fixed frame 31, with the left side being the air outlet and the right side being the air inlet. Fans 36 are fixedly connected inside the two air inlets 35. There are two working modes. When the signature machine needs to be kept warm, the fans 36 are in a stationary state. At this time, the sealing component 38 plays a role in ensuring the sealing effect between the cover plate 32 and the fixed frame 31, reducing the internal heat loss, so that the heat generated by the heating tubes 34 can be concentrated inside the fixed frame 31, maintaining a relatively stable high temperature environment and keeping the signature machine warm. When the signature machine needs to dissipate heat, the fans 36 are activated. When activated, fan 36 at the right air inlet 35 draws external air into the mounting frame 31, while fan 36 at the left air outlet 35 expels hot air from inside. The air flows within the mounting frame 31 under the action of fan 36, carrying away heat generated by the signature machine through heat exchange with its surface, thus achieving a cooling effect. Rotating component 37 assists in the rotation of cover 32, facilitating its opening when operation or maintenance is required. After operation, cover 32 is closed by rotating component 37, and sealed again by sealing component 38, ensuring the insulation mechanism 3 can switch between insulation and heat dissipation modes as needed. The filter mechanism 4, located on the right side inside the insulation mechanism 3, filters the air entering the mounting frame 31 during airflow, preventing impurities from entering and protecting the normal operation of the signature machine. Signature mechanism 5, located on the top of support plate 2, works in conjunction with the insulation mechanism 3 to complete the digital signature comparison for laboratory testing software under suitable temperature conditions. If a conflict occurs, an early warning function is triggered.

[0035] Reference Figure 3 and Figure 4 The filter mechanism 4 includes two connecting frames 41. The right sides of the two connecting frames 41 are fixedly connected to the upper and lower right sides of the inside of the fixed frame 31. The front and rear sides of the two connecting frames 41 are fixedly connected to connecting blocks 42. The left sides of the multiple connecting blocks 42 are threaded with screws 43. The adjacent two connecting frames 41 are provided with grooves 44. The same filter screen 45 is slidably connected inside the two grooves 44.

[0036] Specifically, the right sides of the two connecting brackets 41 are fixedly connected to the upper and lower ends of the right side inside the fixed bracket 31, forming the basic support structure of the filter mechanism 4. Each connecting bracket 41 has a connecting block 42 fixedly connected to its front and rear sides. Multiple connecting blocks 42 are distributed along the connecting bracket 41, providing fixed points for the installation of the filter screen 45. During installation, the left sides of the multiple connecting blocks 42 are connected by threaded screws 43. After the screws 43 are screwed into the connecting blocks 42, they can compress and fix the filter screen 45. Specifically, the grooves 44 opened between the two adjacent connecting brackets 41 provide a sliding installation channel for the filter screen 45. The filter screen 45 slides into the predetermined position between the two connecting brackets 41 through the grooves 44. By tightening the screws 43, it is tightly connected to the connecting blocks 42, thereby clamping and fixing the filter screen 45 between the two connecting brackets 41. When the right-side fan 36 starts, external air enters the insulation mechanism 3 through the right-side air inlet 35 of the fixed bracket 31. The airflow direction is perpendicular to the plane of the filter screen 45, and the filter screen 45... By utilizing its mesh structure, the incoming air is intercepted, blocking dust and impurities on the right side of the filter screen 45. Only air is allowed to pass through the mesh into the internal space of the mounting frame 31. Through the coordinated installation of the connecting frame 41, connecting block 42, screw 43, and groove 44, and the physical interception effect of the filter screen 45, the air entering the mounting frame 31 is filtered, preventing dust and impurities from affecting internal equipment such as the signature machine. When the filter screen 45 needs cleaning or replacement after a period of use, the screw 43 can be unscrewed in the reverse direction to release the fixing constraint on the filter screen 45. Then, the filter screen 45 can be slid out along the groove 44 for cleaning or replacement. After cleaning or replacement, the new or cleaned filter screen 45 is slid back into the groove 44 and tightened again by the screw 43 to ensure that the filtering mechanism 4 continues to perform its function of intercepting and filtering dust and impurities from the incoming air, maintaining a clean internal environment for the insulation mechanism 3 and providing a clean air environment for the stable operation of equipment such as the signature mechanism 5.

[0037] Reference Figure 3 The rotating assembly 37 includes a rotating rod 371, the middle of the outer wall of the rotating rod 371 is fixedly connected to the inner rear side of the cover plate 32, and the top rear ends of the left and right sides of the fixing frame 31 are provided with round holes 372. The left and right sides of the outer wall of the rotating rod 371 are respectively rotatably connected to the inside of the two round holes 372. The rotating assembly 37 also includes two caps 373, the two caps 373 are fixedly connected to the left and right sides of the rotating rod 371, and the opposite sides of the two caps 373 are threaded with bolts 374. The sealing assembly 38 includes two sealing strips 381, the two sealing strips 381 are fixedly connected to the left and right sides of the cover plate 32, and the left and right sides of the inner side of the fixing frame 31 are provided with sealing grooves 382.

[0038] Specifically, the outer wall of the rotating rod 371 is fixedly connected to the inner rear side of the cover plate 32. The left and right sides of the outer wall of the rotating rod 371 are respectively rotatably connected to the round holes 372 opened at the top rear ends of the left and right sides of the fixing frame 31. When it is necessary to open or close the cover plate 32, the rotating rod 371 rotates in the round hole 372, driving the cover plate 32 to rotate around the axis of the rotating rod 371, thereby realizing the opening and closing action of the cover plate 32. The disassembly and installation functions of the rotating assembly 37 are realized by the cap 373 and the bolt 374. The adjacent sides of the two caps 373 are respectively fixedly connected to the left and right sides of the rotating rod 371, and the opposite sides of the caps 373 are threaded with bolts 374. 74. During installation, first align the left and right sides of the rotating rod 371 with the round hole 372 on the fixing bracket 31, then insert the rotating rod 371 into the round hole 372, and then put the cap 373 on the end of the rotating rod 371. Tighten the bolt 374 to make the cap 373 fit tightly with the fixing bracket 31, thereby fixing the rotating rod 371 in the round hole 372 and ensuring that the rotating rod 371 can rotate stably in the round hole 372. During disassembly, unscrew the bolt 374 in the opposite direction, remove the cap 373, and the rotating rod 371 can be pulled out from the round hole 372 to remove the cover plate 32. The sealing assembly 38 consists of two sealing strips 381 and a sealing groove 382. The structure consists of two sealing strips 381 fixedly connected to the left and right sides of the cover plate 32 on adjacent sides. Sealing grooves 382 are provided on both the left and right sides of the internal structure of the fixing frame 31. When the cover plate 32 is closed, the sealing strips 381 move with the cover plate 32 and embed themselves into the sealing grooves 382. Through the tight fit between the sealing strips 381 and the sealing grooves 382, ​​the gap between the cover plate 32 and the fixing frame 31 is filled, preventing airflow and achieving a sealing effect inside the insulation mechanism 3. Through the coordinated operation of the rotating component 37 and the sealing component 38, when operation or maintenance of the signature machine is required, the cover plate 32 can be rotated around the rotating rod 371 via the rotating component 37. After opening and completing the operation, the cover plate 32 is rotated around the rotating rod 371 to close. At this time, the sealing component 38 plays a role in ensuring the sealing of the internal structure of the insulation mechanism 3. When it is necessary to disassemble the cover plate 32, it can be quickly disassembled by using the cap 373 and bolt 374 of the rotating component 37. During installation, the structure of the rotating component 37 also ensures that the installation is stable, allowing the cover plate 32 to rotate flexibly and be easily disassembled and installed. At the same time, it ensures the sealing of the insulation mechanism 3 in the closed state, providing a stable working environment for the signature machine, effectively reducing the interference of external factors on the operation of the signature machine, and ensuring the normal operation of the digital signature comparison work of the laboratory testing software.

[0039] Reference Figure 4 and Figure 5The signature mechanism 5 includes a signature device 51. The bottom of the signature device 51 is fixedly connected to the top of the support plate 2. A display screen 52 is fixedly connected to the top front side of the signature device 51. Multiple buttons 53 are fixedly connected to the bottom front side of the signature device 51.

A lamp holder 6 is fixedly connected to the top left side of the front side of the frame 1. An alarm light 7 is fixedly connected to the front side of the lamp holder 6.

[0040] Specifically, the bottom of the signature device 51 is fixedly connected to the top of the support plate 2. As the core component of the signature operation, the display screen 52 is fixedly connected to the top front side of the signature device 51 to display operation prompts, data information, and comparison results during the signature comparison process. Multiple buttons 53 are fixedly connected to the bottom front side for the operator to input commands, select functions, or confirm operations. The signature pen 55 is fixedly connected to the rear side of the signature device 51 to provide the operator with a signature tool. The placement slot 54 on the top right side of the support plate 2 is used to place the signature pen 55 after the signature operation is completed, so that the signature pen 55 is in a position where... To prevent loss or damage due to careless placement and facilitate quick retrieval for future use, the mounting assembly 56 consists of multiple mounting blocks 561 and screws 562. It securely mounts the signature device 51 onto the support plate 2. The mounting blocks 561 are fixedly connected to the bottom left and right sides of the signature device 51. During installation, the signature device 51 is placed in a suitable position on the support plate 2, aligning the mounting blocks 561 with the pre-set mounting holes on the support plate 2. Then, the screws 562 are screwed sequentially into the tops of the mounting blocks 561. The threaded holes on the support plate 2 securely fix the signature device 51 to the support plate 2, preventing displacement or shaking of the signature device 51 during use. A lamp holder 6 is fixedly connected to the top left end of the front side of the frame 1, and an alarm light 7 is fixedly connected to its front side. This is linked to the internal system of the signature device 51. When the signature device 51 detects a conflict during digital signature comparison, it triggers the alarm light 7 via a circuit signal. Upon receiving the signal, the alarm light 7 begins to flash, visually alerting the operator to an abnormality in the signature comparison, allowing the operator to promptly detect and address the issue. This information is displayed on the signature device 51 and the screen. The combination of button 52 and button 53 enables the input and comparison of digital signatures; the combination of slot 54 and pen 55 standardizes the storage and retrieval process of the signature tool; the mounting block 561 and screw 562 in the mounting component 56 ensure the stability of the signature device 51; and the connection of frame 1, lamp holder 6 and alarm light 7 provides a timely warning by flashing lights when a signature comparison conflict occurs. The coordinated work of all components forms a complete digital signature comparison and conflict warning system, ensuring the accuracy and traceability of the signature operation of the laboratory testing software.

[0041] Working principle: First, the device is installed and initialized. Frame 1 is fixed to the laboratory workbench, and support plate 2 is horizontally installed inside frame 1. The bottom of the fixing frame 31 of the insulation mechanism 3 is fixedly connected to the top of support plate 2. Fans 36 are installed on the left and right air inlets 35 respectively, with the left side being the air outlet fan 36 and the right side being the air inlet fan 36. The rotating rod 371 of the rotating component 37 is inserted into the round hole 372 at the rear end of the top of the fixing frame 31 and fixed by the cap 373 and bolt 374, allowing the cover plate 32 to rotate around the axis of the rotating rod 371. The sealing strip 381 of the sealing component 38 is fixed to the left and right sides of the cover plate 32, corresponding to the sealing groove 382 inside the fixing frame 31. The two connecting brackets 41 of the filter mechanism 4 are fixed inside the fixing frame 31. At the upper and lower ends, connecting blocks 42 are distributed along the front and rear sides of the connecting frame 41. The filter screen 45 is slid into the connecting frame 41 along the groove 44. The filter screen 45 is clamped and fixed by the threaded engagement of screw 43 with the connecting block 42, completing the installation of the air filter structure. The signature device 51 of the signature mechanism 5 is fixed to the top of the support plate 2 by the mounting block 561 and screw 562. The display screen 52, button 53 and signature pen 55 are installed in place. The signature pen 55 is stored in the placement slot 54. The lamp holder 6 and alarm light 7 are fixed to the top front side of the frame 1. The circuit is linked with the signature device 51 to complete the configuration of the conflict warning module. When it is necessary to keep the signature machine warm, the operator rotates the cover plate 32 by rotating component 37 to close the top opening of the fixing frame 31. The sealing strips 381 on the left and right sides of the cover plate 32 are embedded in the sealing grooves 382 of the fixing frame 31. After compression and deformation, they form a sealing barrier to prevent internal heat loss. The power supply to the heating tube 34 is turned on, and the heating tube 34 heats up after being powered on, raising the internal temperature of the fixing frame 31. At this time, the fan 36 is in a stationary state, the air does not flow, and the heat accumulates inside the fixing frame 31, forming a relatively stable high-temperature environment. The power and heat preservation time of the heating tube 34 are set by an external controller to ensure that the signature machine is at a suitable operating temperature and to avoid abnormal operation of the equipment due to low temperature. When the signature machine generates heat and needs to dissipate it, the operator first keeps the cover plate 32 closed and turns on the left and right side fans 36. The fan 36 at the right air inlet 35 draws in outside air, which is then filtered. When the filter 45 of the structure 4 is in operation, dust and impurities are intercepted, and clean air enters the interior of the fixed frame 31. The fan 36 of the left air outlet 35 operates synchronously, expelling the internal hot air and forming air convection. When the air flows over the surface of the signature machine, it carries away the heat of the device through heat exchange, reducing the internal temperature. During the heat dissipation process, the filter mechanism 4 continuously filters the incoming air to prevent impurities from entering and affecting the operation of the signature machine. When the temperature drops below the set threshold, the fan 36 automatically stops, and the device can switch back to the heat preservation mode or remain in standby mode. Under suitable temperature conditions, the operator takes out the signature pen 55 from the placement slot 54, selects the signature comparison function through the button 53, and the display screen 52 displays operation prompts. The operator then uses the signature pen 55 to complete the signature input in the designated area of ​​the signature device 51.The system automatically compares the handwritten signature with the preset signature in the laboratory testing software. If the comparison results match, the display screen 52 shows that the comparison passed. If a signature feature conflict is detected, the internal circuit of the signature generator 51 triggers the alarm light 7, and the alarm light 7 on the lamp holder 6 begins to flash, visually alerting the operator to handle the abnormality. At this time, the conflict details can be viewed on the display screen 52, and the signature can be re-entered or the equipment status can be checked. When maintenance is required on the signature generator or the insulation mechanism 3, the cover 373 can be unlocked by rotating the bolt 374 of the component 37, the rotating rod 371 can be pulled out, and the cover plate 32 can be removed to expose the internal space of the fixing frame 31. If the filter screen 45 needs to be cleaned or replaced, the screw 43 is unscrewed in the reverse direction, the old filter screen 45 is slid out along the groove 44, the new screen is installed, and then tightened again. Check the heating tube 34, the fan 36, and the circuit connection status to ensure that the equipment functions normally. After maintenance is completed, the cover plate is installed in sequence. 32. The rotating rod 371 and cap 373 are fixed by tightening bolt 374. The sealing component 38 restores the sealing performance of the insulation mechanism 3. By switching the heating tube 34 and fan 36 on and off, combined with the insulation and sealing of the sealing component 38, the internal insulation and heat dissipation modes of the fixed frame 31 can be flexibly switched, ensuring that the signature machine operates in a stable temperature environment. The connecting frame 41, filter screen 45 and screw 43 of the filtering mechanism 4 cooperate to filter the incoming air in the heat dissipation mode, preventing dust and impurities from affecting the operation of the equipment and extending the service life of the signature machine. The design of the rotating rod 371 and cap 373 of the rotating component 37 enables the quick opening and closing and disassembly of the cover plate 32, which is convenient for maintenance. The storage design of the signature pen 55 and the placement slot 54 improves the standardization of the operation process. The linkage between the signature device 51 and the alarm light 7 can issue a visual warning in time when there is a signature comparison conflict, ensuring the accuracy and traceability of the detection data.
