Description
TECHNICAL FIELD
[0001] The utility model relates to quantum confinement effect detection foodborne microorganism technical field more specifically, it relates to a kind of high-precision device for detecting foodborne microorganism using quantum confinement effect. BACKGROUND
[0002] In the prior art, the high-precision device for detecting foodborne microorganism using quantum confinement effect is a key equipment in the field of food safety detection, and is widely used in the rapid detection and quantitative analysis of foodborne pathogenic microorganisms such as Salmonella, Escherichia coli and Listeria in food production enterprises, disease control centers, entry-exit inspection and quarantine institutions and third-party detection laboratories. This kind of detection device usually needs to be powered by connecting external power supply through cable to ensure the stable operation of precise components such as quantum dot sensor, optical detection module and signal acquisition system. However, in actual use, the cable interface structure in the prior art is too simple, and the connection between the connector and the cable lacks effective protection measures. In the case of frequent movement of the equipment, repeated plugging and unplugging of the cable or limited space in the use environment, the connection is prone to excessive bending or even breaking, which may cause power interruption, poor contact or short circuit due to wire breakage or insulation layer damage. At the same time, the existing interface cannot adapt to the clamping of cables of different diameters, affecting the power supply reliability and use convenience of the detection equipment.
[0003] Secondly, although some improved equipment can realize the anti-bending protection function of the connection between the cable and the connector by adding some components, and can adapt to the clamping of cables of different diameters, the adjustable protection structure of this kind is relatively simple in design, and lacks mechanical stability and locking reliability. The clamping components may be loosened and displaced due to external factors such as equipment vibration during detection, cable self-gravity traction, dragging by the operator when moving the equipment, and touching by other equipment in the laboratory environment, which may gradually weaken the clamping force of the cable and even completely fail to provide effective anti-bending protection. This not only causes the cable connection to be damaged due to repeated bending, but also may cause problems such as loss of sample data, inaccurate detection results or sudden equipment shutdown during detection due to sudden power failure, affecting the accuracy of foodborne microorganism detection and the continuity of detection work, and increasing the frequency of equipment maintenance and use cost.

[0031] Please refer to Figures 3-5 , as a further embodiment of the whole device: the linkage sleeve 20 is provided with a linkage groove 22 on one side, and a linkage block 23 is slidably arranged in the linkage groove 22, and the linkage block 23 is fixedly connected to one side of the cooperation block 15.
[0032] The end of the coordination rod 10 and the inner wall of the coordination groove 13 are designed in a rounded structure.
[0033] The top pressing spring 24 is movably sleeved outside the top pressing rod 6, one end of the top pressing spring 24 is connected with the constraint sleeve 4, and the other end of the top pressing spring 24 abuts against one side of the rotating plate 7.
[0034] A sliding block 25 is fixed inside the sliding sleeve 5. The inner wall of the sliding sleeve 5 is fixedly connected with the outer wall of the linkage sleeve 20 through the sliding block 25. The side wall of the clamping sleeve 2 is provided with a sliding groove 26. The sliding block 25 is slidably arranged in the sliding groove 26.
[0035] A coordination spring 27 is movably arranged outside the coordination rod 10. The two ends of the coordination spring 27 are respectively connected with the coordination plate 14 and the coordination seat 9.
[0036] A plurality of rubber strips 28 are fixedly arranged on the inner side of the clamping plate 17. A plurality of anti-skid strips 29 are fixedly arranged on the outer sides of the rotating plate 7, the adjusting sleeve 3 and the constraint sleeve 4.
[0037] More specifically, when the cable is connected, the adjusting sleeve 3 is rotated in the opposite direction, which drives the coordination seat 9 to rotate in the opposite direction, and the coordination seat 9 drives the coordination rod 10, the coordination plate 14 and the coordination spring 27 to rotate in the opposite direction. Because of the threaded cooperation between the inner wall of the adjusting sleeve 3 and the outer wall of the sliding sleeve 5, the two sliding sleeves 5 slide in the opposite direction at the same time, and then the sliding sleeve 5 drives the sliding block 25 to slide along the sliding groove 26 to the two sides, so that the sliding block 25 drives the inner linkage sleeve 20 to slide in the opposite direction, and then the linkage sleeve 20 drives the matching block 15 to slide in the opposite direction. At this time, the matching block 15 drives the transmission rod 18, the transmission groove 19, the configuration spring 16 and the clamping plate 17 to slide in the opposite direction, and the matching block 15 drives the matching plate 12 to slide in the opposite direction along the inclined matching groove 11, so that the matching plate 12 drives the matching block 15 to gather inward, and then the matching block 15 drives the linkage block 23 to slide inward along the linkage groove 22, and the matching block 15 drives the transmission rod 18, the configuration spring 16, the transmission groove 19 and the clamping plate 17 to gather inward, and then the rubber strip 28 on the inner wall of the clamping plate 17 contacts the outer wall of the cable, and then the matching block 15 and the clamping plate 17 move closer, so that the transmission rod 18 on one side of the clamping plate 17 slides into the transmission groove 19, and the clamping plate 17 cooperates with the matching block 15 to press the configuration spring 16. When the configuration spring 16 is compressed, the inner walls of the two sets of clamping plates 17 respectively clamp the outer wall of the cable through the rubber strips 28 on the inner sides thereof. At this time, the adjusting sleeve 3 is stopped from rotating, and the coordination seat 9 drives the coordination rod 10 and other components to rotate to the position corresponding to the corresponding coordination groove 13, and then the coordination spring 27 resets to pull the coordination plate 14 to slide inward, so that the coordination plate 14 drives the coordination rod 10 on one side to insert into the corresponding coordination groove 13, and then the restraint sleeve 4 is loosened, the top pressing spring 24 resets to push the restraint sleeve 4, so that the restraint sleeve 4 drives the top pressing rod 6 to slide and reset. When the top pressing spring 24 is completely reset, the top pressing rod 6 no longer penetrates into the rotating hole 8, and then the rotating plate 7 is rotated in the opposite direction, so that the rotating plate 7 drives the rotating hole 8 to rotate and reset to a position not concentric with the top pressing rod 6, so that the top pressing rod 6 supports the restraint sleeve 4 to one side of the rotating plate 7, so that the restraint sleeve 4 cannot easily slide. The inner wall of the restraint sleeve 4 limits the outer wall of the coordination plate 14 again, so that the coordination plate 14 and the coordination rod 10 cannot slide outward, and the coordination rod 10 cooperates with the coordination groove 13 to form a limit, so that the coordination seat 9 and the coordination rod 10 cannot slide outward, thereby realizing the rotation limiting of the coordination seat 9 and the adjusting sleeve 3, so that the adjusting sleeve 3 cannot be accidentally rotated, thereby ensuring the stable clamping of the cable, preventing the cable connection from loosening, and ensuring the protection against bending of the connection between the cable and the connector.
[0038] In summary, the overall device in use or operation: when the cable needs to be connected, first rotate the rotating plate 7 in the positive direction, so that the rotating plate 7 drives the rotating hole 8 to rotate to the position concentric with the top pressure rod 6, then push the constraint sleeve 4, so that the constraint sleeve 4 drives one side of the top pressure rod 6 to gradually slide into the rotating hole 8, and the constraint sleeve 4 will cooperate with the rotating plate 7 to extrude the top pressure spring 24 sleeved on the outside of the top pressure rod 6, and the inner wall of the constraint sleeve 4 will no longer limit the outer wall of the coordination plate 14, then rotate the adjusting sleeve 3 in the positive direction, the adjusting sleeve 3 drives the coordination rod 10, the coordination plate 14 and the coordination spring 27 to rotate in the positive direction through one side of the coordination seat 9, then the inner wall of the coordination groove 13 extrudes one end of the coordination rod 10, and then one end of the coordination rod 10 will slide out of the coordination groove 13, and the coordination rod 10 will drive the other end of the coordination plate 14 to move outward, and the coordination plate 14 will drive the coordination spring 27 to stretch outward, and at the same time, the inner wall of the adjusting sleeve 3 and the outer wall of the sliding sleeve 5 are connected by threads, and the two sliding sleeves 5 are oppositely arranged, the threads on both ends of the inner wall of the adjusting sleeve 3 are symmetrically arranged, and the sliding block 25 and the sliding groove 26 cooperate to realize the rotation limiting of the sliding sleeve 5, then the two sliding sleeves 5 will synchronously slide towards the middle, and the sliding sleeve 5 will drive the sliding block 25 to slide along the sliding groove 26, then the sliding block 25 will drive the inner side of the linkage sleeve 20 to slide towards the middle, then the linkage sleeve 20 drives the cooperation block 15 to move towards the middle through the cooperation of the linkage groove 22 and the linkage block 23, and the cooperation block 15 will drive the transmission rod 18, the transmission groove 19, the configuration spring 16 and the clamping plate 17 to move towards the middle, and at the same time, the cooperation block 15 will drive the cooperation plate 12 arranged on the other side to slide along the cooperation groove 11 which is arranged in an inclined manner, then the cooperation plate 12 will drive one side of the cooperation block 15 to move outwardly, so that the cooperation block 15 drives one side of the linkage block 23 to slide along the linkage groove 22, and the cooperation block 15 will drive the transmission rod 18, the configuration spring 16, the transmission groove 19 and the clamping plate 17 to move outwardly, so that the clamping plate 17 and other components spread to the outermost side, and at the same time, the two sliding sleeves 5 move to the position where the distance between them is the shortest, at this time, stop rotating the adjusting sleeve 3, then insert the cable into the clamping sleeve 2, and connect the cable connector with the detection assembly 1.
[0039] When the cable is connected, rotate the adjusting sleeve 3 in the opposite direction. The adjusting sleeve 3 will drive the coordination seat 9 on one side to rotate in the opposite direction, and the coordination seat 9 will drive the coordination rod 10, the coordination plate 14 and the coordination spring 27 to rotate in the opposite direction. Because of the threaded cooperation between the inner wall of the adjusting sleeve 3 and the outer wall of the sliding sleeve 5, the two sliding sleeves 5 will slide to the two sides at the same time. Then the sliding sleeve 5 will drive the sliding block 25 to slide to the two sides along the sliding groove 26, so that the sliding block 25 drives the inner side linkage sleeve 20 to slide in the opposite direction. Then the linkage sleeve 20 will push the matching block 15 on one side to slide in the opposite direction. At this time, the matching block 15 will drive the transmission rod 18, the transmission groove 19, the configuration spring 16 and the clamping plate 17 on one side to slide in the opposite direction. The matching block 15 will drive the matching plate 12 on one side to slide in the opposite direction along the inclined matching groove 11, so that the matching plate 12 drives the matching block 15 to gather inward. Then the matching block 15 will drive the linkage block 23 on one side to slide inward along the linkage groove 22. The matching block 15 will drive the transmission rod 18, the configuration spring 16, the transmission groove 19 and the clamping plate 17 to gather inward. Then the rubber strip 28 on the inner wall of the clamping plate 17 contacts the outer wall of the cable. Then the matching block 15 and other components continue to move, and the distance between the matching block 15 and the clamping plate 17 is close, so that the transmission rod 18 on one side of the clamping plate 17 slides into the transmission groove 19, and the clamping plate 17 cooperates with the matching block 15 to press the configuration spring 16. When the configuration spring 16 is compressed, the inner walls of the two sets of clamping plates 17 respectively clamp the outer wall of the cable through the rubber strips 28 on the inner sides. At this time, stop rotating the adjusting sleeve 3, and make the coordination seat 9 drive the coordination rod 10 and other components to rotate to the position corresponding to the corresponding coordination groove 13. Then the coordination spring 27 resets to pull the coordination plate 14 inward, so that the coordination plate 14 drives the coordination rod 10 on one side to insert into the corresponding coordination groove 13. Then release the restraint sleeve 4, and the top pressure spring 24 resets to push the restraint sleeve 4, so that the restraint sleeve 4 drives the top pressure rod 6 on one side to slide and reset. When the top pressure spring 24 is completely reset, the top pressure rod 6 no longer penetrates into the rotating hole 8. Then rotate the rotating plate 7 in the opposite direction, so that the rotating plate 7 drives the rotating hole 8 to rotate and reset to the position not concentric with the top pressure rod 6, so that the top pressure rod 6 supports the restraint sleeve 4 to one side of the rotating plate 7, so that the restraint sleeve 4 cannot easily slide. Then the inner wall of the restraint sleeve 4 limits the outer wall of the coordination plate 14 again, so that the coordination plate 14 and the coordination rod 10 cannot slide outward. The coordination rod 10 cooperates with the coordination groove 13 to form a limit, so that the coordination seat 9 and the coordination rod 10 cannot slide outward, thereby realizing the rotation limiting of the coordination seat 9 and the adjusting sleeve 3, so that the adjusting sleeve 3 cannot be accidentally rotated, thereby ensuring the stable clamping of the cable, preventing the cable connection from loosening, and ensuring the protection against bending of the connection between the cable and the connector.
