In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. It should be noted that if there are directional indications (such as up, down, left, right, front, back...) in the embodiments of the utility model, the directional indications are only used to explain the relative positional relationship, movement, etc. between the components under a certain specific posture (as shown in the drawings). If the specific posture changes, the directional indications also change accordingly.

[0036] See also Figure 1 and 5 The utility model embodiment provides a centrifuge airtight hanging basket structure, including a hanging basket cover 1, a rotor hanging basket 2 and a lock buckle 5, wherein the hanging basket cover 1 is detachably mounted on the rotor hanging basket 2 via the lock buckle 5;

[0037] The basket cover 1 has fixed parts 4 on both sides thereof, and the rotor basket 2 has raised parts 6 on both sides thereof. The lock buckle 5 is hinged on the fixed parts 4 and can be rotated to match with the raised parts 6.

[0038] In the utility model, the lock buckle is hinged on the edge of the cover body of the hanging basket cover, and the protrusion is fixed on the mouth of the rotor hanging basket. The lock buckle can be rotated and buckled with the protrusion to play a sealing role between the hanging basket cover and the rotor hanging basket. The lock buckle has two implementation forms, one is a lock buckle with a connecting end at one end and a free end at the other end and an overall ring shape, and the other is a lock buckle including a buckle, a spring pin and a buckle ring. Both of them utilize the buckle cooperation between the ring buckle and the protrusion to achieve the sealing reinforcement effect between the hanging basket cover and the hanging basket. Both are made of stainless steel metal and have stronger durability. The former has a simpler structure and is more convenient to operate, and the latter has better hinge elasticity and better sealing effect.

[0039] See also Figure 1-3 In one embodiment, the lock buckle 5 includes a buckle 7, a spring pin 8 and a buckle ring 9. The spring pin 8 is inserted into the fixing portion 4. The buckle 7 is rotatably mounted on the fixing portion 4 via the spring pin 8. The buckle ring 9 is inserted into the buckle 7 and can be rotatably buckled to the protrusion 6. With such a design, the lock buckle 5 in this embodiment is made of stainless steel and has a stronger durability. Although the seal between the hanging basket cover 1 and the rotor hanging basket 2 is also achieved by the buckle fit of the buckle and the protrusion, the buckle ring 9 can be rotated relative to the buckle 7. The buckle 7 can also be rotated compared to the spring pin 8. The rotation range of the entire lock buckle 5 is larger, the hinge elasticity is better, and the pressing effect on the hanging basket cover 1 is better.

[0040] See also Figure 3-4 In this embodiment, a groove 601 is formed on the bottom surface of the protruding portion 6, and the buckle 9 rotates to the bottom of the protruding portion 6 and engages with the groove 601. With this design, the buckle 9 and the groove 601 are engaged and matched, and the degree of fastening between the lock buckle 5 and the protruding portion 6 is further improved.

[0041] See also Figure 5-7 In another embodiment, one end of the lock buckle 5 is a connecting end 501, which is inserted into the fixing portion 4 and can rotate around the fixing portion 4, and the other end of the lock buckle 5 is a free end 502, which can be buckled to the protrusion 6 as the connecting end 501 rotates. With this design, the lock buckle 5 in this embodiment is made of stainless steel, which is more durable, and the seal between the basket cover 1 and the rotor basket 2 is achieved by the buckle of the ring and the protrusion, which has a simpler structure and more convenient operation.

[0042] See also Figure 7-8In this embodiment, a groove 601 is provided below the protrusion 6 and on the wall of the rotor hanging basket 2. The free end 502 is in an arc shape that is recessed toward the connection end 501. The free end 502 rotates into the groove 601 and contacts the bottom of the protrusion 6. With this design, the groove 601 provides sufficient operating space for moving the free end 502.

[0043] See also Figure 1 and 5 In this embodiment, the two sides of the rotor hanging basket 2 are mirror-imaged with hanging interfaces 3 for assembling with the horizontal rotor. With this design, the rotor hanging basket 2 is assembled with the horizontal rotor via the hanging interfaces 3 on both sides, completing the installation of the airtight hanging basket structure on the rotor.

[0044] See also Fig. 9 In this embodiment, the caliber of the basket cover 1 matches the caliber of the rotor basket 2, and a non-rotation slot 101 is provided on the outer wall of the mouth of the basket cover 1 along the circumferential direction, and a non-rotation block 201 is fixed on the inner wall of the mouth of the rotor basket 2 along the circumferential direction, and the non-rotation slot 101 is engaged with the non-rotation block 201. In this design, the non-rotation slot 101 is engaged with the non-rotation block 201 to prevent the basket cover 1 from rotating in the circumferential direction of the mouth of the rotor basket 2, thereby enhancing the connection stability between the two.

[0045] See also Fig.10 In this embodiment, a sealing ring 10 is embedded on the bottom surface of the opening of the hanging basket cover 1, and the sealing ring 10 can contact the top surface of the opening of the rotor hanging basket 2. With this design, the sealing ring 10 further improves the sealing effect of the airtight hanging basket structure under the compression of the lock buckle 5.

[0046] See also Fig.11 The embodiment of the utility model further provides a centrifuge basket structure, including a rotor basket 2, and the two sides of the rotor basket 2 are mirror-imaged with hanging interfaces 3 for assembly with a horizontal rotor. With this design, the rotor basket 2 is assembled with the horizontal rotor via the hanging interfaces 3 on both sides, completing the installation of the ordinary non-airtight basket structure on the rotor. Since there are no other accessories on the rotor basket 2, it is compatible with the airtight basket structure and the ordinary non-airtight basket structure, and does not affect the normal switching use. When the airtight basket structure is used, the lock buckle 5 can be fastened as required to complete the sealing. When the ordinary non-airtight basket structure is used, the basket cover 1 does not need to be installed.

The rotor hanging basket 2 is installed and matched with the horizontal rotor via the hanging interface 3. When the horizontal rotor rotates, the rotor hanging basket 2 is subjected to the centrifugal force and is thrown to a horizontal state. The hanging basket cover 1 rotates and points to the inside of the horizontal rotor. The lock buckle 5 is contained in the inside of the horizontal rotor, and the windward area does not increase, thereby avoiding increasing wind resistance and not causing excessive wind noise.

[0050] Similarly, when the non-airtight hanging basket structure is assembled with the horizontal rotor, since there is no need to install the hanging basket cover 1, only the rotor hanging basket 2 needs to be installed on the horizontal rotor, so when the horizontal rotor rotates, the wind resistance will not increase.
