Embodiment

Below in conjunction with accompanying drawing and embodiment, the utility model is described further:

Refer to Fig. 1, the utility model relates to a kind of cell scraper 100, and it is for the cell of 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 and can be switched back and forth between the first angle and the second angle with respect to scraping cutter bar 10 under external force by rotation axis 30.

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, the second end 112 that it comprises first end 110 and is connected with first end 110.Spaced apart some the grooves 114 that extend along its length, the frictional force while gripping to increase operator of being provided with of first end 110 outside surfaces.Some ribs 116 along the circumferential direction spacing ring are around in first end 110 outside surfaces, thereby some grooves 114 are divided into some sections along first end 110 bearing of trends, the comfort level with the intensity that increases first end 110 when gripping.Wherein, the surface of the surface of every rib 116 and first end 110 is in same plane.In the present embodiment, first end 110 outside surfaces offer four along its groove 114 extending longitudinally.

The second end 112 is also substantially cylindrical, and its undersized is in the size of first end 110.The second end 112 outside surfaces are 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 directions along first end 110 and tilts, and in the time that operator grips the second end 112, finger can be contacted to bearing surface 118, is convenient to the application of force.Understandably, in some other embodiment, first end 110 can be determined as required with quantity and the bearing of trend of the second end 112 surface grooves 114, does not repeat them here.Meanwhile, the second end 112 outside surfaces also can arrange as the rib 116 of 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.It is tabular that connection section 13 is substantially, and it is tilted to extend to form away from the end of first end 110 by the second end 112 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 extending along different directions.In the present embodiment, axis body comprises the first axle body 31 extending along first direction and the second axle body 33 that extends and be connected with the first axle body 31 along second direction.Wherein, the first axle body 31 and the structural similitude of the second axle body 33 and all substantially cylindrical.The first axle body 31 is along the first direction setting that is parallel to first end 110.The second axle body 33 is along the second direction setting perpendicular to first direction.So, both mutually vertical and by with connection section 13 junctions centered by intersect to form cross.Understandably, in some other embodiment, the first axle body 31 all can be determined as required with quantity and the bearing of trend of the second axle body 33, and for example, rotation axis 30 can arrange along three different directions and extend and mutual cross-coupled axis body.

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 U font substantially.The first connection piece 532 and the second connection piece 534 and two spacing preiections 536 that Connection Block 53 comprises diapire 530, extended to form by the relative both sides of diapire 530.Blade 51 is extended to form by two relative surfaces of diapire 530 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.The 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 first connection piece 532 is parallel to by diapire 530 both sides that blade 51 bearing of trends are relative with the second connection piece 534 and extends to form.The first connection piece 532 and the second connection piece 534 are along the axis hole 538 that offers respectively axial symmetry perpendicular to blade 51 directions.In the first axle body 31 is removably arranged in corresponding axis hole 538 with the second axle body 33.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 protrude from diapire 530 and be connected in the first connection piece 532 and the second connection piece 534 between, thereby distance when effectively controlling the first connection piece 532 and the second connection piece 534 and being opened under external force between the two.Between two spacing preiections 536, equal the length of the first axle body 31 or the second axle body 33 along the distance that is parallel to the first connection piece 532 bearing of trends, thereby the first axle body 31 or the second axle body 33 are accommodated and are limited between two spacing preiections 536 in the time that 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 deformation can occur under external force for it.

Please, in the lump referring to Fig. 1 and Fig. 4, be connected in the first axle body 31 opposite ends as original state take 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, thereby 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 with respect to scraping cutter bar 10 in the first angle, and the bearing of trend of blade 51 is vertical with the bearing of trend of scraping cutter bar 10.

In the time need to switching the angle of blade 51, operator's revolving scraper bar 10 or wing 50 one in both, makes Connection Block 53 with respect to rotation axis 30 90-degree rotations.Now, two axis holes 538 disengagings coordinate with the first axle body 31.When the first connection piece 532 and two axis holes 538 of the second connection piece 534 are arranged in the relative two ends of the second axle body 33.Blade 51 has switched to the second angle by the first original angle, and the bearing of trend of blade 51 is parallel with the bearing of trend of scraping cutter bar 10.Now, when Connection Block 53 interfixes with rotation axis 30, realize the change of wing 50 with respect to scraping cutter bar 10 angles.

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 can conversion 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 in the time realizing different angles and change.

For a person skilled in the art, can be according to technical scheme described above and design, make other various corresponding changes and distortion, and these all changes and distortion all should belong to the protection domain of the utility model claim within.
