[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this does not limit the present invention.

[0016] Example 1, as Figures 1-3As shown, the present invention discloses a basket connection structure for a floor-standing centrifuge, comprising a body 1, inside which a motor 2 is fixedly installed at its lower part. The output shaft of the motor 2 is vertically upward and coaxially fixedly connected to a rotating shaft 3. The rotating shaft 3 is fixedly connected to a rotor 4. The basket connection structure of the floor-standing centrifuge also includes a basket 5. Vertical hanging grooves 501 are provided on both sides of the basket 5. The upper end of the hanging grooves 501 is closed and located on the outer wall of the basket 5, and the lower end of the hanging grooves 501 extends to the bottom of the basket 5. The rotor 4... It includes a central part 401 and multiple radially extending support arms 402. The central part 401 is cylindrical, and the support arms 402 are fixedly distributed circumferentially outside the cylindrical surface of the central part 401. Each support arm 402 has a hanging pin 403 on both sides. The two hanging slots 501 of the basket 5 are respectively hung on the opposing hanging pins 403 between two adjacent support arms 402. The bottom of the rotor 4 is connected to the inner bottom of a rotating drum 7. The support arms 402 and the basket 5 are both located inside the rotating drum 7. A cover 701 is provided on the top of the rotating drum 7.

[0017] In use, the items to be centrifuged are first placed in the basket 5. Then, the hanging slots 501 on both sides of the basket 5 are hung by gravity onto the hanging pins 403 between the support arms 402. The line connecting the upper ends of the hanging slots 501 on both sides of the basket 5 is located above the center of gravity of the basket 5. Combined with the weight of the items to be centrifuged, the basket 5 can be suspended stably. During centrifugation, centrifugal force makes the hanging pins 403 stick tightly to one end of the hanging slots 501, preventing the basket 5 from flying out. If the basket 5 is not properly hung or the items inside the basket 5 fly out, the rotating drum 7 outside the rotor 4 and the basket 5 can block the items, preventing them from flying out of the equipment and further improving the safety of the equipment. At the same time, items can also be placed on the rotating drum 7 for centrifugation.

[0018] In Example 2, as a further preferred embodiment of Example 1, the hanging groove 501 is a dovetail groove, and the hanging pin 403 is a conical pin. The small end of the conical pin is connected to the support arm 402, and the large end of the conical pin extends into the dovetail groove. The dovetail groove and the conical pin can further limit the position of the suspended basket 5 and prevent the suspended basket 5 from moving laterally.

[0019] In Example 3, as a further preferred embodiment of Example 1, the upper part of the rotating shaft 3 is tapered, the central hole of the rotor 4 is a tapered hole, a stepped hole 404 is provided at the upper end of the tapered hole, a locking member 6 is provided above the stepped hole 404, a stud 601 is provided at the bottom of the locking member 6, and a threaded hole is provided at the top of the rotating shaft 3. The stud 601 engages with the threaded hole to press the locking member 6 onto the rotor 4. The rotating shaft 3 and the rotor 4 can be effectively aligned through the tapered surface fit; the locking member 6 locks the rotor 4 and the rotating shaft 3 together through the engagement of the stud 601 and the threaded hole, facilitating quick disassembly and replacement of the rotor 4 to adapt to different specifications of the suspended basket 5.

[0020] In Example 4, as a further preferred embodiment of Example 3, a handle 702 is provided at the center of the cover 701, and a through hole is provided at the center of the handle 702. A guide post 602 is provided at the top of the locking member 6, and the guide post 602 extends into the through hole. The guide post 602 cooperates with the through hole to facilitate the alignment when the cover 701 is fastened onto the rotary drum 7, so that the cover 701 is correctly installed.

[0021] Example 5, as a further preferred embodiment of Example 1, also includes a fixed bucket 8, which is fixedly connected to the machine body 1. The rotating bucket 7 is located inside the fixed bucket 8. Setting the fixed bucket 8 can further improve the safety of the equipment and prevent items from flying out during rotation. The output shaft of the motor 2 or the rotating shaft 3 passes through the bottom of the fixed bucket 8 and is connected to the rotor 4.

[0022] In Example 6, as a further preferred embodiment of Example 1, a hollow groove 405 is provided in the middle of the support arm 402. The hollow groove 405 can reduce the weight of the support arm 402, achieve lightweighting, reduce the load on the centrifuge, and extend the service life of the equipment.
