Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described further:
Refer to Fig. 1, the present invention relates to a kind of cell scraper 100, it is for the cell in harvested cell culturing bottle.Cell scraper 100 comprises scraping cutter bar 10, rotation axis 30 and wing 50.Wing 50 is rotationally connected with on scraping cutter bar 10 by rotation axis 30 and also can switches back and forth between the first angle and the second angle relative to scraping cutter bar 10 under external force.
Please in the lump referring to Fig. 2, the connection section 13 that scraping cutter bar 10 comprises grip part 11 and is connected with grip part 11.Grip part 11 is substantially cylindrical, it the second end 112 comprising first end 110 and be connected with first end 110.First end 110 outside surface is spaced apart is provided with some the grooves extended along its length 114, to increase frictional force when operator grips.Some ribs 116 along the circumferential direction spacing ring are around in first end 110 outside surface, thus some grooves 114 are divided into some sections along first end 110 bearing of trend, to increase the intensity of first end 110 and comfort level when gripping.Wherein, the surface of every bar rib 116 and the surface of first end 110 are in same plane.In the present embodiment, first end 110 outside surface offers four along its groove 114 extending longitudinally.
The second end 112 is also substantially cylindrical, and it is dimensioned slightly smaller than the size of first end 110.The second end 112 outside surface is also arranged at intervals with some grooves 114 extending longitudinally.The second end 112 is provided with bearing surface 118 away from the upper surface of first end 110 one end.Bearing surface 118 points to the second end 112 direction along first end 110, for when operator grips the second end 112, finger can be contacted at bearing surface 118, is convenient to force.Understandably, in some other embodiment, quantity and the bearing of trend of first end 110 and the second end 112 surface groove 114 can be determined as required, do not repeat them here.Meanwhile, the second end 112 outside surface also can arrange the rib 116 as analog structure on first end 110, to increase intensity and the comfort level of the second end 112.
Connection section 13 is arranged at the second end 112 one end away from first end 110.Connection section 13 is substantially in tabular, and it is tilted to extend to form by the end of the second end 112 away from first end 110 at an angle.In the present embodiment, the angle between connection section 13 and the second end 112 is obtuse angle.
Rotation axis 30 is arranged at connection section 13 one end away from the second end 112.Rotation axis 30 comprises the axis body extended along different directions.In the present embodiment, axis body comprises along the first axle body 31 of first direction extension and extends and the second axle body 33 be connected with the first axle body 31 along second direction.Wherein, the structural similitude of the first axle body 31 and the second axle body 33 and all substantially cylindrical.The first axle body 31 is arranged along the first direction being parallel to first end 110.The second axle body 33 is arranged along the second direction perpendicular to first direction.So, both mutually vertical and by with connection section 13 junction centered by intersect to form cross.Understandably, in some other embodiment, quantity and the bearing of trend of the first axle body 31 and the second axle body 33 all can be determined as required, and such as, rotation axis 30 can arrange and extend and mutual cross-coupled axis body along three different directions.
Please in the lump referring to Fig. 3, wing 50 is rotationally connected with the first axle body 31 or the relative two ends of the second axle body 33.The Connection Block 53 that wing 50 comprises blade 51 and is connected with blade 51.Connection Block 53 is arranged between blade 51 and rotation axis 30, and it is substantially in U-shaped.Connection Block 53 comprises diapire 530, the first connection piece 532 extended to form by the relative both sides of diapire 530 and the second connection piece 534 and two spacing preiections 536.Blade 51 is extended to form by two surfaces that diapire 530 is relative respectively with the first connection piece 532 and the second connection piece 534.Wherein, blade 51 is arranged between the first connection piece 532 and the second connection piece 534.First connection piece 532 and the second connection piece 534 are arranged at the one side of Connection Block 53 towards rotation axis 30.
The both sides that first connection piece 532 is parallel to blade 51 bearing of trend relative with the second connection piece 534 by diapire 530 extend to form.First connection piece 532 and the second connection piece 534 are along offering axially symmetrical axis hole 538 respectively perpendicular to blade 51 direction.The first axle body 31 and the second axle body 33 are removably arranged in corresponding axis hole 538.Wherein, the distance between the first connection piece 532 and the second connection piece 534 is slightly less than the length of the first axle body 31 or the second axle body 33.Two spacing preiection 536 intervals to protrude from diapire 530 and are connected between the first connection piece 532 and the second connection piece 534, thus effectively to control when the first connection piece 532 and the second connection piece 534 are opened under external force distance between the two.Equal the length of the first axle body 31 or the second axle body 33 between two spacing preiections 536 along the distance being parallel to the first connection piece 532 bearing of trend, thus the first axle body 31 or the second axle body 33 are accommodated and are limited between two spacing preiections 536 when Connection Block 53 is installed on rotation axis 30.Wherein, the line between two axis holes 538 is between two spacing preiections 536.In the present embodiment, the first connection piece 532 and the second connection piece 534 are made up of softwood matter, and it under external force deformation can occur.
Please in the lump referring to Fig. 1 and Fig. 4, be connected to the first axle body 31 opposite end for original state with the first connection piece 532 and the second connection piece 534 below.Now, the two ends that the first axle body 31 is relative are contained in corresponding axis hole 538, thus Connection Block 53 is held on the first axle body 31.The two ends that the second axle body 33 is relative are defined between two spacing preiections 536.Blade 51 is in the first angle relative to scraping cutter bar 10, and namely the bearing of trend of blade 51 is vertical with the bearing of trend of scraping cutter bar 10.
When needing to switch the angle of blade 51, the one in both operator's revolving scraper bar 10 or wing 50, makes Connection Block 53 relative to rotation axis 30 90-degree rotation.Now, two axis holes 538 disengagings coordinate with the first axle body 31.When first connection piece 532 and two axis holes 538 of the second connection piece 534 are arranged in the second axle body 33 relative two ends.Blade 51 has switched to the second angle by the first original angle, and namely the bearing of trend of blade 51 is parallel with the bearing of trend of scraping cutter bar 10.Now, Connection Block 53 and rotation axis 30 realize the change of wing 50 relative to scraping cutter bar 10 angle while interfixing.
In the present embodiment, wing 50 is held on the first axle body 31 or the relative two ends of the second axle body 33 and can change between the first axle body 31 and the second axle body 33 under external force, thus being fixed on rotation axis 30 of making that wing 50 also can be stable when realizing different angles and changing.
For a person skilled in the art, according to technical scheme described above and design, other various corresponding change and distortion can be made, and all these change and distortion all should belong within the protection domain of the claims in the present invention.
