Abstract
The utility model discloses a device is prevented falling by test cup for centrifuge, including installing rotor block, the rotatable test cup of establishing between two support arms of being equipped with a plurality of support arms on the motor, be equipped with on the test cup with support arm matched with restriction test cup rotation angle's spacing boss. The utility model discloses a characteristics have installed additional on the test cup with the spacing boss of support arm matched with of rotor block, when the test cup focus unstability of being equipped with centrifugal sample, when continuing anticlockwise rotation, spacing boss on the test cup just with the rotor block cooperation, stop the test cup to resume anticlockwise rotation under the support arm is spacing, prevent in the test cup hangs the sample upside down and is thrown away the test cup to prior art's is not enough has been compensatied.
Description
Technical Field
The utility model belongs to centrifuge, concretely relates to a device is prevented down to test cup for centrifuge.
Background
The centrifugal machine is used for separating matter, belongs to basic laboratory equipment and is used widely in life science, medicine, chemistry, environment protection and other fields. The test cup of the centrifuge is an important component of the centrifuge, is matched with the rotor body for use, and is arranged on the motor to separate a sample on the test cup. The existing test cup structure is not provided with the anti-falling device, if the centrifugal sample gravity center deviates from the bottom of the test cup by a large distance, when the motor stops working when the centrifugation is completed, the gravity center is unstable, the test cup continues to rotate anticlockwise, and the sample hung upside down on the test cup is thrown out of the test cup.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a device is prevented down to test cup for centrifuge to prevent that the test cup from hanging the sample upside down and being thrown away the test cup.
Realize the utility model discloses the technical scheme that the purpose was adopted as follows:
the utility model provides a device is prevented falling by test cup for centrifuge, including rotor block, the rotatable test cup of establishing between two support arms of installing a plurality of support arms on the motor, be equipped with on the test cup with support arm matched with restriction test cup rotation angle's spacing boss.
The test cup can be rotatably arranged on the hanging pins of the two supporting arms.
The limiting boss is in threaded connection with the test cup.
Advantageous effects
The utility model discloses a characteristics have installed additional on the test cup with the spacing boss of support arm matched with of rotor block, when the test cup focus unstability of being equipped with centrifugal sample, when continuing anticlockwise rotation, spacing boss on the test cup just with the rotor block cooperation, stop the test cup to resume anticlockwise rotation under the support arm is spacing, prevent in the test cup hangs the sample upside down and is thrown away the test cup to prior art's is not enough has been compensatied.
The technical scheme of the utility model is further explained in the following with the attached drawings.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic view of the usage state of the present invention.
Detailed Description
See fig. 1, the utility model provides a device is prevented down to test cup for centrifuge, including install rotor block 3, the rotatable test cup 1 of establishing between two support arms 301 of being equipped with a plurality of support arms 301 on motor 4, be equipped with on the test cup 1 with support arm 301 matched with limits test cup 1 rotation angle's spacing boss 2.
The test cup 1 can be rotatably arranged on the hanging pins of the two supporting arms 301, and the limiting boss 2 is in threaded connection with the test cup 1.
When the centrifuge works, under the conditions that the centrifugal samples in the test cup 1 are too many and the center of gravity is unstable, the motor 4 stops working after centrifugation, and when the test cup 1 rotates anticlockwise again and topples over, the limiting boss 2 on the test cup 1 is limited in contact with the rotor body 3, so that the test cup cannot hang upside down, the samples in the test cup are prevented from being thrown out of the test cup, and as shown in fig. 2, the test cup is slowly restored to a horizontal state.
Claims (3)
1. The utility model provides a device is prevented down to test cup for centrifuge, is including installing the rotor block who establishes a plurality of support arms on the motor, rotatable the test cup of establishing between two support arms, characterized by be equipped with on the test cup with support arm matched with limit boss of restriction test cup rotation angle.
2. The apparatus as claimed in claim 1, wherein the test cup is rotatably mounted on the hanging pins of the two support arms.
3. The anti-tilting device for the test cup of the centrifuge as claimed in claim 1 or 2, wherein the limit boss is in threaded connection with the test cup.
