When the outer sampling disc 230 enters the first channel 211, the locking wheel 650 is meshed with the connecting rack 442 on the limiting frame 440, the outer end of the triggering block 410 gradually moves outwards from the mounting cavity 111, the triggering block 410 drives the connecting rack 442 of the limiting frame 440 to move downwards, the locking wheel 650 is enabled to rotate, the locking wheel 650 pulls the pushing block 620 to squeeze the second spring 630, the outer sampling disc 230 is enabled to deform, the side wall of the outer sampling disc 230 is further enabled to be tightly abutted to the side wall of the first channel 211, and tightness of the inside of the first channel 211 is ensured.
In this embodiment, the upper end of the housing 110 is fixedly connected with a telescopic rod 710, the length of the telescopic rod 710 can be adjusted automatically as required, and the upper end of the telescopic rod 710 is fixedly provided with a handle 720.
In combination with the above embodiment, the working process of the present invention is as follows:
in operation, the length of the telescopic rod 710 is adjusted according to the depth of the etching solution container, the buoyancy block 310 is at the lowermost end of the housing 110 under the action of gravity in the initial state, and the adjusting rod 322 is pushed to slide forward in the adjusting groove, so that the guide rod 323 is positioned in the first guide groove 132, and the outer sampling disk 230 is positioned outside the first channel 211.
The lower end of the shell 110 is slowly inserted into a container filled with a solution of etching solution, when the trigger block 410 contacts the bottom of the container, the telescopic rod 710 is continuously pushed to move downwards, the trigger block 410 is extruded, the outer end of the trigger block 410 gradually moves towards the inside of the installation cavity 111, when the trigger block 410 completely enters the installation cavity 111, the limiting frame 440 fixedly connected with the inner end of the trigger block 410 synchronously moves upwards, the limiting toothed rod 441 on the limiting frame 440 is separated from the gear mesh of the driving wheel 510, at the moment, the driving wheel 510 can rotate, the buoyancy block 310 slides upwards along the first guide groove 132, the pushing rod 320 arranged on the connecting frame 311 fixedly arranged between the two buoyancy blocks 310 gradually pushes the sliding block 550 to slide upwards along the first slideway 120, when the guiding rod 323 moves to the starting point of the lower end of the first arc section of the first limiting groove, the guiding rod 323 continuously moves upwards along the first guide groove 132, the first arc section of the first limiting groove gradually promotes the pushing rod 320 to slide rightwards, and when the guiding rod 323 moves to the top point of the first arc section of the first guide groove 132, the pushing rod 320 does not push the sliding block 550 to abut against the first slideway 120. When the sliding block 550 slides upwards along the first slideway 120, the sliding block 550 drives the sliding plate to slide upwards synchronously, the second toothed bar 530 fixedly connected to the sliding plate drives the driving wheel 510 to rotate, the driving wheel 510 pulls the inner sampling plate to slide along the first channel 211 through the first toothed bar 520, so that the outer sampling plate gradually enters the first channel 211, at this time, the first channel 211 is filled with etching liquid, and multiple groups of sampling components gradually fill with the etching liquid along with the upward movement of the buoyancy block 310 along the first guide groove 132 in the sampling block 210.
When the outer sampling plate 230 is fully inserted into the first channel 211, the locking wheel 650 rotatably disposed on the inner sampling plate 220 engages the connecting rack on the stopper 440. When the buoyancy block 310 moves to the upper end of the first guide groove 132, the telescopic rod 710 is pulled upwards slowly, so that the lower end of the housing 110 is not abutted against the bottom of the container any more, the trigger block 410 moves outwards gradually under the action of the restoring force of the first spring 430, the inner end of the trigger block 410 pulls the limiting frame 440 to move downwards synchronously, the limiting rack of the limiting frame 440 moves downwards to drive the locking wheel 650 to rotate, the locking wheel 650 pulls the pushing block 620 to be close to the outer sampling disc 230 gradually through the third toothed bar 640, and the second spring 630 between the outer sampling disc 230 and the pushing block 620 is compressed gradually. Because the outer sampling plate 230 is made of rubber soft material, the outer sampling plate 230 is deformed, so that the side wall of the outer sampling plate 230 is tightly abutted against the side wall of the first channel 211, and liquid entering the sampling block 210 is prevented from leaking out.
After the outer end of the trigger block 410 is completely protruded from the inside of the housing 110, the adjusting lever 322 is pushed to move backward in the adjusting groove, so that the guide bar 323 is separated from the first guide groove 132 and enters the second guide groove 142. Along with the gradual extraction of the housing 110 from the container, the buoyancy block 310 is subject to the action of gravity, and the buoyancy block 310 has a tendency to slide downwards along the second guide groove 142, but at this time, the rotation of the rotating wheel is limited by the limiting toothed bar 441 on the limiting frame 440 fixedly connected to the inner end of the trigger block 410, and at this time, the rotating wheel cannot rotate, so that the buoyancy block 310 cannot slide downwards along the second guide groove 142.
When the shell 110 is completely pulled out from the container, the shell 110 is vertically arranged on a desktop, the telescopic rod 710 is pushed to move downwards, the trigger block 410 is pressed inwards, the trigger block 410 is gradually moved towards the inside of the installation cavity 111, the limit toothed rod 441 fixedly connected to the limit frame 440 is gradually used for limiting the rotating wheel, when the buoyancy block 310 slides downwards along the second guide groove 142 under the action of gravity, the guide rod 323 continuously moves downwards along the second guide groove 142 when the guide rod 323 moves to the starting point of the upper end of the second arc section of the second guide groove, the second arc section of the second guide groove gradually promotes the push rod 320 to slide rightwards, and when the guide rod 323 moves to the top point of the second arc section of the second guide groove 142, the push rod 320 is not abutted against the sliding block 550 any more, and at this time, the push rod 320 pushes the sliding block 550 to move to the lower end of the first slide 120. When the sliding block 550 slides downwards along the first slideway 120, the sliding block 550 drives the sliding plate to synchronously slide downwards, the second toothed bar 530 fixedly connected with the sliding plate drives the driving wheel 510 to rotate, the driving wheel 510 pushes the inner sampling plate to slide along the first channel 211 through the first toothed bar 520, so that the outer sampling plate is gradually far away from the inside of the first channel 211, at the moment, the etching liquid in the first channel 211 is discharged outwards, and the etching liquid in the first channel 211 is subjected to fine detection by using professional equipment. The etching solution in the sampling block 210 of the plurality of sets of sampling assemblies is gradually discharged outwards from top to bottom as the buoyancy block 310 moves downwards along the first guide groove 132.
After the etching liquid in the multiple groups of sampling components is discharged, the sampling components are cleaned, and the cleaned device is dried, so that the accuracy of next sampling is ensured.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
