[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0031] Reference Figure 1 - Figure 3This utility model provides an embodiment of a metal surface cleanliness testing device, comprising a housing 1, a lid 2 hinged to one side of the housing 1, a handle 3 installed on the other side of the housing 1, a storage component inside the lid 2, and a sponge pad 4 inside the housing 1. The sponge pad 4 effectively improves the safety and storage of the instrument. A fixing component is installed inside the sponge pad 4; the fixing component includes a fixing frame 5, a sleeve 6 fixedly connected to the inner side of the fixing frame 5, a slider 7 slidably connected inside the sleeve 6, and a connecting block 9 fixedly connected to the end of the slider 7 away from the fixing frame 5. A clamping plate 10 is fixedly connected to the end away from the fixed frame 5. The clamping plate 10 is used to fix the instrument. A first spring 8 is set inside the sleeve 6. The first spring 8 is used for rebound and reset. One end of the first spring 8 is fixedly connected to the inside of the sleeve 6, and the other end of the first spring 8 is fixedly assembled with the slider 7. There are 3 to 4 sleeves 6 arranged in a circle. An elastic band 11 is fixedly connected between the connecting blocks 9. The clamping plate 10 is an arc-shaped sheet structure. A rubber pad 21 is fixedly connected at the bend of the box body 1. The rubber pad 21 is used for anti-collision and shock absorption. Fixing strips 22 are fixedly connected at the four corners of the opening side of the box body 1.
[0032] When testing the cleanliness of metal parts, the instrument is first taken out of the housing 1 and assembled. Then, the sensor is aligned with the metal surface, and the measurement button on the instrument is pressed. The instrument will identify and quantify the contaminants on the surface of the metal sample through its internal sensors and algorithms. During this process, to prevent errors caused by the operator's hand vibration, the instrument is inserted between the clamps 10. During the insertion process, the clamps 10 are squeezed, which in turn pushes the clamps 10 to move. The movement of the clamps 10 causes the connecting block 9 to squeeze the slider 7, causing the slider 7 to slide into the sleeve 6. The movement of the slider 7 applies pressure to the first spring 8, causing it to deform. As the clamps 10 continue to move outward, the elastic band 11 is stretched and deformed. When the instrument is inserted into the appropriate position, the downward insertion is stopped. At this time, the force generated by the reset of the first spring 8 and the elastic band 11 will limit and fix the instrument, ensuring that the instrument remains horizontal during the test, and the operator can free up one hand to perform other operations.
[0033] Reference Figure 2 - Figure 5The storage assembly includes a reinforcing cloth 12, a connecting plate 16, and a fixing block 14. The fixing block 14 is fixedly connected to the four corners of the reinforcing cloth 12. The fixing block 14 is used to fix the reinforcing cloth 12 with the locking block 19. The fixing block 14 has a locking groove 15 inside. The connecting plate 16 is fixedly connected to the four corners inside the box cover 2. The locking post 17 is fixedly connected to the side wall of the connecting plate 16. The locking post 17 has a groove 18 inside. The locking block 19 is provided on the side wall of the locking post 17. The locking block 19 is used to fix the fixing block 14. The second spring 20 is provided on the side wall of the locking block 19. The second spring 20 is used to rebound and reset. One end of the second spring 20 is fixedly connected to the inside of the groove 18. The other end of the second spring 20 is fixedly connected to the side wall of the locking block 19. The locking block 19 is slidably connected to the inside of the groove 18. The side wall of the locking post 17 is slidably connected to the inside of the locking groove 15. The isolation bag 13 is fixedly connected to the side wall of the reinforcing cloth 12. The isolation bag 13 is used to hold sundries and accessories.
[0034] To prevent the attached probes, calibration plates, and other accessories from becoming disorganized, a storage bag is installed inside the cover 2 for easy access and cleaning. After aligning the slot 15 with the pin 17, the fixing block 14 is moved downwards to insert the pin 17 into the slot 15. At this time, the slot 15 presses the pin 19 into the groove 18. The entry of the pin 19 compresses the second spring 20, causing it to contract. As the fixing block 14 continues to move downwards, the pin 19 loses the pressure of the slot 15, and the second spring 20 rebounds, locking the pin 19 against the side wall of the fixing block 14 and securing the reinforcing cloth 12. When the storage bag needs cleaning after prolonged use, the fixing block 14 is moved by moving the reinforcing cloth 12, which compresses the pin 19 into the groove 18. Simultaneously, the second spring 20 is compressed and contracts, releasing the pin 19 from the fixing block 14 and allowing it to be removed for cleaning.
[0035] Working principle: When starting the test, align the sensor with the metal surface and press the measurement button on the instrument. The instrument will identify and quantify the contaminants on the surface of the metal sample through its internal sensors and algorithms. During this process, to prevent errors caused by operator hand vibration, the instrument is inserted between the clamping plates 10. During insertion, the clamping plates 10 are squeezed, causing the slider 7 to slide into the sleeve 6, which compresses the first spring 8 and causes it to deform. As the clamping plates 10 move outward, the elastic band 11 is stretched and deformed. When the instrument is inserted into the appropriate position, the first spring 8 and the elastic band 11 return to their original positions, and the force generated therefrom will restrict and fix the instrument.
[0036] To prevent the attached probes, calibration plates, and other accessories from being misplaced, a storage bag is installed inside the cover 2. By aligning the slot 15 with the post 17 and inserting it, the locking block 19 is squeezed into the groove 18. As the fixing block 14 moves downward, the locking block 19 loses the pressure of the slot 15, and the second spring 20 rebounds, locking the locking block 19 against the side wall of the fixing block 14 and fixing it to the reinforcing cloth 12. When the storage bag needs to be cleaned, the fixing block 14 is moved by moving the reinforcing cloth 12, which squeezes the locking block 19 into the groove 18, causing the second spring 20 to contract under pressure, releasing the fixing of the fixing block 14, and allowing it to be removed for cleaning.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
