FIG. 1 is a schematic diagram of a magnetic sleeve detection device according to the present utility model; fig. 2 is a cross-sectional view of the magnetic sleeve detecting device of the present utility model. The magnetic sleeve detection device is generally used for detecting whether the magnetic sleeve is installed on the magnetic sleeve installation column or not, and loss caused by failure of an extraction experiment due to leakage of the magnetic sleeve is avoided. The magnetic sleeve detection device mainly comprises a magnetic sleeve mounting column 1, a sensor 2, a spring 3, a detection tube 4, a magnetic sleeve 5 and a magnetic rod 6.
As shown in fig. 5 and 6, the magnetic sleeve mounting column 1 is a schematic structural view, and the magnetic sleeve mounting column 1 is used for mounting the detection tube 4 and the magnetic sleeve 5. The magnetic sleeve mounting column 1 comprises a main mounting column 11, a secondary mounting column 12, a magnetic rod through hole 13 and a mounting groove 14. The auxiliary mounting column 12 is integrally connected to the first bottom of the main mounting column 11, and the diameter of the main mounting column 11 is larger than that of the auxiliary mounting column 12 (the auxiliary mounting column 12 is used for subsequently mounting the detection tube 4 and the magnetic sleeve 5, and the diameter of the main mounting column 11 is larger than that of the auxiliary mounting column 12) so as to ensure that the elastic piece can abut against the lower surface of the main mounting column 11, thereby facilitating the realization of the detection function of the magnetic sleeve 5, and when the magnetic sleeve mounting column 1 is in the state shown in fig. 5, the bottom of the main mounting column 11 is the first bottom of the main mounting column 11).
The magnetic rod through holes 13 penetrate through the main mounting columns 11 and the auxiliary mounting columns 12, the magnetic rod through holes 13 are used for subsequently mounting the magnetic rods 6, and the diameters of the magnetic rod through holes 13 are equal to the diameters of the magnetic rods 6 so as to limit the movement of the magnetic rods 6 and prevent the magnetic rods 6 from shifting when lifting. The mounting groove 14 is formed in the outer side wall of the first bottom of the main mounting column 11, and the mounting groove 14 is used for fixing the sensor 2 subsequently. As shown in fig. 6, the main mounting post 11, the sub mounting post 12, and the bar magnet through hole 13 are coaxially disposed.
The sensor 2 is fixed in the mounting groove 14 and is used for detecting the movement of the detection tube 4 (the sensor 2 is a photoelectric switch of the type EE-SX671-WR which is commercially available). The sensing groove 21 is formed in the bottom of the sensor 2, and the sensing piece 43 is inserted into the sensing groove 21 when the detecting tube 4 moves, so that the successful installation of the magnetic sleeve 5 is determined.
As shown in fig. 7 and 8, in order to schematically illustrate the structure of the detection tube 4, the detection tube 4 is inserted into the secondary mounting post 12, and includes a detection main tube 41, a detection secondary tube 42, a sensing piece 43, a first limit groove 44 and a second limit groove 45. The detection auxiliary pipe 42 is integrally connected to the second bottom of the detection main pipe 41, and the diameter of the detection main pipe 41 is larger than the diameter of the detection auxiliary pipe 42 (when the detection pipe 4 is in the position shown in fig. 7, the bottom of the detection main pipe 41 is the second bottom of the detection main pipe 41). The first limiting groove 44 is formed in the main detection pipe 41, and the second limiting groove 45 is formed in the auxiliary detection pipe 42 and communicated with the first limiting groove 44.
The diameter of the first limiting groove 44 is larger than that of the auxiliary mounting column 12, so that a gap is reserved between the detection main pipe 41 and the auxiliary mounting column 12, and the elastic piece is convenient to place. The diameter of the second limiting groove 45 is equal to that of the auxiliary mounting column 12, and the auxiliary mounting column 12 limits the detection auxiliary pipe 42 to ensure that the detection main pipe 41 does not deviate left and right when moving. The sensing piece 43 is integrally connected to the outer side wall of the top of the main detecting tube 41 and is matched with the sensing groove 21, when the main detecting tube 41 ascends, the sensing piece 43 is driven to ascend synchronously, the ascending sensing piece 43 is inserted into the sensing groove 21, and accordingly the successful installation of the magnetic sleeve 5 is determined (when the detecting tube 4 is located at the position shown in fig. 7, the sensing piece 43 is fixed at one end of the main detecting tube 41 far away from the second bottom).
The elastic piece is arranged in the gap between the main detection pipe 41 and the auxiliary mounting column 12, and when the detection pipe 4 ascends, the elastic piece is compressed to deform, and the elastic piece is selected to play a buffering role in detection, so that the integral structure is prevented from being damaged by rigid extrusion. As shown in fig. 2, the elastic member is a spring 3, the spring 3 is sleeved on the auxiliary mounting post 12, one end of the spring 3 abuts against the bottom of the first limiting groove 44, and the other end of the spring 3 abuts against the first bottom of the main mounting post 11 (rubber balls can also be selected as the elastic member).
As shown in fig. 9 and 10, the magnetic sleeve 5 is schematically shown in the structure, and the magnetic sleeve 5 is inserted into the end of the secondary mounting post 12 away from the primary mounting post 11, and comprises an insertion section 51, a guiding section 52, a magnetic attraction section 53, a sealing section 54 and an arc-shaped portion 55. The inside diameter of the plug section 51 is equal to the diameter of the secondary mounting post 12 so that the plug section 51 will be inserted into the secondary mounting post 12 during installation. The top of the inserting section 51 abuts against the detecting auxiliary tube 42, and when the inserting section 51 is installed, the detecting tube 4 is driven to synchronously move upwards, so that the sensing piece 43 is inserted into the sensing groove 21, and the completion of the installation of the magnetic sleeve 5 is confirmed.
When the magnetic sleeve 5 is in the state shown in fig. 9, the inserting section 51, the guiding section 52, the magnetic attraction section 53 and the closing section 54 are sequentially arranged from top to bottom. The guiding section 52 is integrally connected to the bottom of the inserting section 51, and the guiding section is tapered in diameter, so that the movement of the subsequent magnetic rod 6 can be guided by the tapered diameter design, and the magnetic rod 6 can be ensured to be inserted into the magnetic attraction section 53 more easily. The magnetic attraction section 53 is integrally connected to the bottom of the guide section 52, the inner diameter of the magnetic attraction section 53 is equal to the diameter of the magnetic rod 6, and when the magnetic rod 6 is in operation, the magnetic rod 6 is directly inserted into the magnetic attraction section 53 after passing through the insertion section 51 and the guide section 52.
The closed section 54 is integrally connected to the bottom of the magnetic attraction section 53, and the magnetic rod 6 inserted into the magnetic attraction section 53 abuts against the upper surface of the closed section 154, so that the magnetic beads in the liquid are attracted through the closed section 54. The arc portion 55 is disposed outside the closed section 54, and compared to a right angle design, the arc portion 55 can absorb more magnetic beads.
The working principle of the magnetic sleeve detection device is as follows:
after the magnetic sleeve 5 is taken, the magnetic sleeve 5 is inserted on the auxiliary mounting column 12, in the process, the magnetic sleeve 5 can drive the detection tube 4 to move upwards against the elastic force of the spring 3, the sensing piece 43 at one end of the detection main tube 41 synchronously moves upwards, and when the sensing piece 43 is inserted in the sensing groove 21, the fact that the magnetic sleeve 5 is correctly mounted at the moment is proved (when the magnetic sleeve 5 is correctly mounted, the sensing piece 43 is inserted in the sensing groove 21, the sensor 2 sends a signal to the background controller, and the background controller starts an indicator lamp).
The above embodiments are provided to illustrate the technical concept and features of the present utility model and are intended to enable those skilled in the art to understand the content of the present utility model and implement the same, and are not intended to limit the scope of the present utility model. All equivalent changes or modifications made in accordance with the spirit of the present utility model should be construed to be included in the scope of the present utility model.
