[0029] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] Example

[0031] like Figure 1 As shown, a centrifugal chamber cover locking device for a blood component separator comprises a housing 1, a pair of locking blocks 2 and a reset member.

[0032] A first rotating shaft 3 is horizontally provided on the side of the shell 1 facing the centrifugal chamber, and the two locking blocks 2 are rotatably arranged on the first rotating shaft 3, and the two locking blocks 2 are symmetrically arranged; a locking groove 4 is provided on the top end of the locking block 2 facing the shell 1; a slot 5 is provided on the lower part of one side of the locking block 2 facing the shell 1.

[0033] like Figure 1 and Figure 2 As shown, the reset member is arranged on the side of the housing 1 facing away from the centrifugal bin; the reset member includes a second rotating shaft 6, a torsion spring 7 and a cam block 8; the second rotating shaft 6 is arranged on the side of the housing 1 facing away from the centrifugal bin and is parallel to the first rotating shaft 3; the torsion spring 7 is sleeved on the second rotating shaft 6; the cam block 8 is rotatably arranged on the second rotating shaft 6, and the cam block 8 is opposite to the corresponding locking block 2; the inner end of the cam block 8 has a plug-in portion 9; one end of the torsion spring 7 is plugged into the second rotating shaft 6, and the other end is plugged into the cam block 8.

[0034] A spring 10 is provided on the housing 1 below the locking block 2, one end of the spring 10 is connected to the housing 1, and the other end is connected to the bottom of the locking block 2, and the spring 10 is in a compressed state. In this embodiment, a limiting groove 11 is provided at the bottom of the locking block 2, and the upper part of the spring 10 is located in the limiting groove 11, which plays a certain limiting role on the spring 10.

[0035] like Figure 4 As shown, when the hatch cover of the centrifugal chamber needs to be closed, the hatch cover is closed on the centrifugal chamber, the hatch cover presses the locking block downward, and the locking block rotates around the first rotating shaft, and finally the slot on the locking block is clamped on the plug-in part on the cam block, thereby locking the hatch cover.

[0036] When the door needs to be opened, the cam block 8 is pushed downward, and finally the plug-in portion 9 is separated from the slot 5. Under the action of the elastic force of the spring 10, the locking block 2 rotates backward to open the door.

[0037] In this embodiment, if Figure 1As shown, a cover plate 12 is provided on the side of the shell 1 facing away from the locking block 2, the cover plate 12 is located below the second rotating shaft 6, and a matching portion 13 is provided on the top of the cover plate 12, and the cover plate 12 is rotatably set on the second rotating shaft 6 through the matching portion 13; the lower surface of the outer end of the cam block 8 is in contact with the top of the cover plate 12; in this way, the staff can make the cam block 8 rotate downward in a clockwise direction to open the hatch by pushing the cover plate 12 upward.

[0038] Furthermore, if Figure 3 As shown, a cover body 14 is provided on the side of the housing 1 facing away from the centrifugal bin, and the cover body 14 is fixed to the cover plate 12 by bolts. Such a configuration can provide a certain degree of protection for the reset member without affecting the use of the cover plate 12.

[0039] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
