In addition, two pin blocks 41 on the same side are arranged, friction force is further increased, and in the actual use process, the pin blocks 41 and the corresponding first track 31 and second track 22 can be adjusted by combining the normal required reagent weight, so that friction forces with different sizes are obtained, and the stability of the pin blocks 41 and the shaft tube 3 in fixation is improved.
It is noted that when one of the pin blocks 41 secures the sleeve 2 and the shaft tube 3, the other pin block 41 is disengaged from the other shaft tube 3.
Referring to fig. 6, a locking ring 32 is connected to one end of each shaft tube 3 facing the movable ring 4, the locking ring 32 is concentric with the sleeve 2 and is located at the outer side of the sleeve 2, and the first rail 31 and the second rail 22 are located at the outer side of the sleeve 2 corresponding to the locking ring 32 and the inner end surface of the locking ring 32, respectively, and the pin block 41 can slide into the annular space between the locking ring 32 and the outer end of the sleeve 2 and cooperate with the first rail 31 and the second rail 22 at the same time.
Referring to fig. 8, the pin block 41 is in a block shape and is simultaneously inserted into a space formed in the corresponding end surfaces of the first rail 31 and the second rail 22, and the end surfaces of the pin block 41 are offset from the fixing bars in the first rail 31 and the second rail 22.
Referring to fig. 3, the limiting function in this case is mainly realized by the adjusting block 7, a threaded section 34 is disposed at the outer end of one side of the shaft tube 3, a pushing block 6 capable of guiding and moving along the axial direction of the tube 1 is disposed in the tube 1, the pushing block 6 is disposed at one end of the tube 1 away from the soft plug 21, and the pushing block 6 is in threaded fit with the shaft tube 3, and when the shaft tube 3 rotates, is in threaded fit with the shaft tube 3 and moves reciprocally along the axial direction of the tube 1.
The adjusting block 7 is arranged at the outer side of the shaft tube 3, one end of the adjusting block faces the outer side of the tube body 1 and is in threaded fit with the shaft tube 3, one end of the adjusting block 6 facing the pushing block is parallel to the end face of the pushing block 6, the pushing block 6 can reciprocate on the threaded section 34 due to the rotation of the shaft tube 3, when the shaft tube 3 is rotated in the forward direction, the pushing block 6 moves towards one side direction of the adjusting block 7, at the moment, the adjusting block 7 is close to the pushing block 6 by rotating the adjusting block 7 (the position of the adjusting block 7 is adjusted in advance), and therefore after the pushing block 6 is abutted against the adjusting block 7, the adjusting block 7 limits the pushing block 6, and the shaft tube 3 is prevented from continuing to rotate.
Because regulating block 7 is independent of sleeve pipe 2 setting, be screw thread fit between the two, regulating block 7 is hollow cylinder structure, regulating block 7 cover is in sleeve pipe 2's outside and with sleeve pipe 2 screw thread fit (refer to fig. 6), promptly when sleeve pipe 2 rotates, regulating block 7 can rotate (fix sleeve pipe 2 and rotatory regulating block 7 in the time of adjusting), frictional force that produces when sleeve pipe 2 rotates is far less than the snap-in force between screw thread section 34 on regulating block 7 and sleeve pipe 2, and be located the side middle part of body 1 and offered a round hole 13 that the diameter is greater than regulating block 7 diameter, when regulating block 7 rotates on sleeve pipe 2 for body 1, regulating block 7 can pass round hole 13 and remove towards body 1 inside (outside) direction.
Referring to fig. 9 and 10, when the push block 6 contacts the adjusting block 7 along with the rotation of the sleeve 2, the push block 6 cannot move in the pipe body 1, that is, no matter how the dial sleeve 5 is rotated, the push block 6 cannot move because the movement of the push block 6 is limited by the adjusting block 7, and the natural sleeve 2 cannot rotate under the action of the screw force.
Referring to fig. 2, the adjusting block 7 is tubular, and in order to accurately determine the number of rotation cycles required and the shaking standards of different reagents before and after when the adjusting block 7 is adjusted, a scale 71 is specially provided on the outer end surface of the adjusting block 7 along the axial direction of the tubular body 1, where the scale 71 may be the distance between the adjusting block 7 and the pushing block 6, or may be tested in advance, and the reading of the scale 71 corresponds to the number of rotation cycles of the shaft tube 3, which is not limited too much.
When the adjusting block 7 rotates to axially move along the pipe body 1, the adjusting block 7 moves towards the inside of the pipe body 1, so that the scale 71 correspondingly changes, and the current maximum rotatable cycle number can be judged according to the scale 71.
For example, one of the scales 71 is marked as a, the a scale represents that the maximum rotation circle number of the shaft tube 3 can be limited by the current position of the adjusting block 7 to be 5 weeks, namely, when the sleeve 3 rotates for 5 weeks, the pushing block 6 moves to a distance just to enable the pushing block 6 to abut against the end face of the adjusting block 7, at the moment, the shaft tube 3 cannot continue rotating, the generated pushing force is far smaller than the biting force between the adjusting block 7 and the thread section 34, at the moment, the shifting sleeve 5 is loosened, the shaft tube 3 rebounds for 5 weeks under the action of elastic potential energy, and the purpose of controlling the rotation circle number is achieved, so that when different reagents need to be 5 weeks, only the mark A on the adjusting block 7 is flush with the plane where the round hole 13 is located, and when different reagents need to be rotated for different circle numbers, only the adjusting block 7 needs to be adjusted to the mark of the corresponding circle number, and the maximum rotation circle number of the shifting sleeve 5 is controlled by limiting the maximum stroke of the pushing block 6.
In order to ensure that the shifting sleeve 5 can be easily and not slipped when rotating, anti-slip patterns are formed on the end face of the movable ring 4, which faces the outer side of the pipe body 1, so that the friction force when the shifting sleeve 5 is driven to rotate when the movable ring 4 is held by a hand is improved.
Referring to fig. 2, regarding the resetting of the shaft tubes 3, in which one shaft tube 3 (elastically rotatable) has a rebound property, when the shaft tube 3 is completely stationary, the initial position is achieved by aligning the pin blocks 41 only, and the pin blocks 41 can be inserted into the concave space of the shaft tube 3 to be fixed by observing the positions of the approximate pin blocks 41;
in order to facilitate the resetting of the other shaft tube 3 (which cannot elastically rotate), namely, a marking groove 11 is formed at the outer end of the tube body 1 along the axial direction thereof, a visual window 12 which can see the shaft tube 3 (which cannot elastically rotate) is formed at the position corresponding to the marking groove 11, a resetting mark 35 is arranged at the outer end of the shaft tube 3, and the resetting mark 35 is observed from the visual window 12 by rotating the dial sleeve 5 until the relative position between the dial sleeve 5 and the shaft tube 3 at the moment is judged to be the same as the initial position, at the moment, the pin block 41 moves towards one side of the shaft tube 3, and the pin block 41 can be smoothly inserted into the concave space of the shaft tube 3.
The outer end of the sleeve 5 is also provided with a groove body identical to the marking groove 11, so that after the relative positions of the shaft tube 3 and the sleeve 5 are adjusted (the sleeve can not elastically rotate), the pin block 41 and the shaft tube 3 are fixed and rotated until the marking groove 11 is aligned with the groove body at the outer end of the sleeve 5, and the position of the sleeve 5 and the other shaft tube 3 (which can elastically rotate) at the moment is restored as before.
Working principle:
firstly, a poking sleeve 5 is rotated, when the poking sleeve 5 rotates, a sleeve 2 is driven to rotate, so that test tubes connected to one side of the sleeve 2 synchronously rotate, at the moment, movable rings 4 which can reciprocate along the axial direction of the sleeve 2 on the poking sleeve 5 are utilized to lock different shaft tubes 3 respectively, when the poking sleeve 5 is rotated to be fixed with the shaft tubes 3 which elastically rotate in a tube body 1, the shaft tubes 3 can rotate, meanwhile, elastic potential energy is accumulated, in the rotating process, the movable rings 4 can be fixed with the sleeve 2, the sleeve 2 can rotate, the test tubes connected to one side of the sleeve 2 can start rotating and shaking uniformly, after the poking sleeve 5 is released, the elastic potential energy is released instantaneously, the sleeve 2 can reversely rotate, so that the aim of reciprocating rotation and shaking uniformly is achieved, and the degree of medicine mixing is improved;
