本考案は、試料を遠心分離するチユーブ穴を有
するロータの、チユーブキヤツプを締め付ける際
のロータ固定装置に関するものである。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a rotor fixing device for tightening a tube cap of a rotor having a tube hole for centrifuging a sample.

Figure 2 shows the rotor shape. Conventionally, in a rotor where the tube is tightened with a cap, if the lower part of the rotor is cylindrical, there is no fixing device such as a jig to fix the rotor, and when tightening the cap, the rotor is held by hand and tightened, making it unstable. The cap was not tightened enough and there were individual differences.
本考案の目的は、上記したロータのキヤツプを
安定して締め付けられる様、ロータ下部円筒部を

This invention focuses on the restoring force by the spring, the linear movement by the cam, and the increase in force by the lever, and when the handle is pulled down, the spring is fixed so that the rotor is fixed by pressing a holder with the same diameter against the lower cylindrical part of the rotor. , the cam, handle, and holder have been devised.
本考案の実施例を第１図、第２図に示す。 An embodiment of the present invention is shown in FIGS. 1 and 2.

状態でロータ１０のキヤツプ１２を締め付ける。 In this embodiment, the rotor is placed on a fixing device, and the lower cylindrical portion of the rotor is fixed with a holder.
Place the rotor 10 on the guide 7. By pushing down the handle 2, the cam 3 rotates, and the movable holder 5 performs a linear movement together with the distance piece 9 on the base 1, contacts the lower cylindrical part of the rotor 10, and moves together with the guide 7 and the rotor 10. Move to fixed holder 6. At this time, the spring 4 is also compressed. Rubber 8 is provided on the rotor lower cylindrical contact surfaces of the movable holder 5 and the fixed holder 6, and the rotor 10 is pressed and fixed by rotation of the cam 3. In this state, the cap 12 of the rotor 10 is tightened.

移動させ元の状態に戻る。 When removing the rotor 10, when the handle 2 is pushed up, the movable holder 5 is moved by the compressed spring 4.
moves together with the cam 3, allowing the rotor 10 to be removed. Similarly, when the rotor is removed, the spring 4 between the fixed holder 4 and the guide 7 also expands to move the guide 7 and return to its original state.
この様にハンドル７の操作のみで従来手で保持
していたロータ１０を固定させることができる様
になつた。 In this way, the rotor 10, which was conventionally held by hand, can now be fixed only by operating the handle 7.
本考案によれば、ロータを手で保持しないで済
み、キヤツプの締め付け不足をなくすことができ
る。
According to the present invention, it is not necessary to hold the rotor by hand, and it is possible to eliminate insufficient tightening of the cap.
