It is effectively attached with shaft 2 with connecting column 13, and shaft 2 can rotate in swivel nut 5, and then phase can occur with blind nut 12
To rotation, convenient for when adjusting the first bristle 10 by rotating shaft 2, blind nut 12 and swivel 1 will not all be synchronized with shaft 2
Rotation, and then realize the function of adjusting, the top of 12 inner wall of blind nut is rotatably equipped with connecting column 13, specifically, connecting column
13 for blind nut 12 and positioning column 14 to be attached, so that can be driven by connecting column 13 when blind nut 12 moves
Positioning column 14 is mobile, and the bottom end of connecting column 13 is fixedly installed with positioning column 14, and the bottom of positioning column 14 is along the circumferential direction at equal intervals
Open up there are four slot 15, the inside of slot 15 is plugged with inserted block 16, and the bottom of inserted block 16 is fixedly mounted on the top of swivel 1
Swivel 1 when inserted block 16 is inserted into 15 inner cavity of slot, can be carried out position with positioning column 14 and fixed by portion in use；
The inner wall of positioning column 14 is along the circumferential direction equally spaced to open up that there are four limiting slot 17, the inside of four limiting slots 17
It is connected with limited block 18, and four limited blocks 18 are fixedly mounted on the outer of shaft 2 close to the axial one side of positioning column 14
On side, specifically, pass through the use of limiting slot 17 and limited block 18, so that during rotating backward blind nut 12, blind nut 12
When driving positioning column 14 mobile by connecting column 13, the cooperation of limited block 18 and limiting slot 17 can allow positioning column 14 to be protected always
The axial direction held along shaft 2 is moved, at this point, positioning column 14 not can rotate, in shaft 2 between corresponding slot 15 and inserted block 16
Radial direction will not shift, after rotating forward blind nut 12, in the insertion slot 15 that inserted block 16 can be more accurate, more just
It in operation, rotates backward blind nut 12 and it is allowed to separate with stud 11, just in 12 motion process of blind nut, blind nut 12 passes through connecting column
13 drive positioning columns 14 move simultaneously allows inserted block 16 be detached from slot 15, be rotated further by shaft 2 or rotation swivel 1, allow shaft 2 and swivel
1 relatively rotates, at this point, drive bevel gear 8 rotates relative to driven wheel of differential 7 along 1 circumferencial direction of swivel, from mantle
Gear 7 is rotated by the drive of drive bevel gear 8, and screw rod 6 is driven to rotate, swivel nut 5 occurs on the outside of screw rod 6 it is mobile and to turn
It is stretched out on the outside of body 1, at this point, swivel nut 5 drives the movement of the first bristle 10 by the first brush board 9, therefore, it is possible to according in centrifuge tube
Diameter adjusts the position of the first bristle 10, and the cleaning brush is allowed to be suitable for the centrifuge tube of different inner diameters size.
Working principle: in use, blind nut 12 is rotated backward, it can be upward while blind nut 12 rotates backward on the outside of stud 11
Movement, at this point, blind nut 12 drives positioning column 14 to move upwards by connecting column 13, after inserted block 16 is detached from slot 15, rotation
Shaft 2 allows shaft 2 to relatively rotate with swivel 1, and shaft 2 drives drive bevel gear 8 to rotate, and drive bevel gear 8 drives driven
Bevel gear 7 rotates, and driven wheel of differential 7 drives screw rod 6 to rotate, at this point, swivel nut 5 is moved on screw rod 6 and stretched to 1 outside of swivel
Out, screw rod 6 drives the movement of the first bristle 10 by the first brush board 9, and the circumferential area diameter that the first bristle 10 is formed becomes larger, when the
After one bristle 10 contact with centrifugation inside pipe wall, stopping allows turn and 1 relatively rotate with shaft 2, and 12 sets of blind nut exists later
On stud 11 and blind nut 12 is rotated forward, blind nut 12, which is moved axially and driven by connecting column 13 in 11 outer stud 11 of stud, to be determined
Position column 14 is mobile, and after positioning column 14 moves a certain distance, inserted block 16 can be inserted into slot 15, at this point, positioning column 14 cooperates
Inserted block 16 can effectively be fixed between swivel 1 and shaft 2, and then reach and consolidate to the first bristle 10 after adjusting
Fixed effect.
