Description

Technical Field

[0001] The utility model relates to the technical field of centrifuges, in particular to a rotor of a high-speed bench centrifuge. Background Art

[0002] In multiple fields such as biology, chemistry, and medicine, centrifuges, as a commonly used separation device, are of self-evident importance. And as a type of centrifuge, high-speed bench centrifuges have been widely used in laboratories due to their high rotational speed and high efficiency. However, during the use of high-speed bench centrifuges, the fixing method of the rotor has always been a key factor affecting its performance and stability.

[0003] Currently, most of the rotors of high-speed bench centrifuges on the market are fixed by bolts. Although this fixing method is simple and direct, it has the following significant defects:

[0004] I. Inconvenient operation

[0005] The method of fixing by bolts requires the operator to manually tighten the bolts, which not only increases the complexity of the operation but also reduces the work efficiency. Especially in the case of frequently replacing or adjusting the rotor, the operator needs to frequently use tools such as socket wrenches to tighten and loosen the bolts, which is both time-consuming and laborious.

[0006] II. Prone to damage

[0007] During high-speed rotation, a large frictional force will be generated between the bolt and the nut, which is likely to cause wear and even damage to the bolt and the nut. Once the bolt or the nut is damaged, a new bolt or nut needs to be replaced, which not only increases the maintenance cost but may also affect the normal use of the centrifuge.

[0008] Therefore, in view of the defects of the existing fixing method of the rotor of high-speed bench centrifuges, it is necessary to develop a new type of rotor fixing method. Content of the Utility Model

[0009] The utility model designs a rotor of a high-speed bench centrifuge to solve the above-mentioned existing problems.

[0010] In order to achieve the above technical purposes and reach the above technical effects, the utility model is realized by the following technical solutions:

[0011] A rotor of a high-speed bench centrifuge, including a rotor, a groove is opened in the middle of the upper end surface of the rotor, a long hole is penetrated through the inner bottom wall surface of the groove, and a plurality of screw holes are opened on the inner bottom wall of the groove and around the outside of the long hole;

[0012] A plug rod is inserted into the long hole. A top seat is arranged at the top end of the outer wall of the plug rod and embedded in the groove. A plurality of through holes are formed through the outer wall of the top seat. A plurality of clamping mechanisms are inserted on the outer wall of the plug rod.

[0013] It further includes a drive shaft. A plurality of jacks are formed through the outer wall of the drive shaft. A second spring is arranged on the inner bottom wall of the drive shaft. A scraper is arranged on the top wall of the second spring. A connecting rod is arranged in the middle of the top of the scraper. The top end of the connecting rod extends out of the drive shaft and is provided with a round block.

[0014] Further, the clamping mechanism includes a socket. A first spring is arranged on the inner side wall of the socket. A spring seat is arranged on the inner end wall of the first spring. An insertion block is arranged on the inner side wall of the spring seat, and the inner end of the insertion block extends into the plug rod.

[0015] Further, both the upper and lower ends of the inner side wall surface of the insertion block are designed as inclined slopes.

[0016] Further, the number of the grooves is equal to that of the top seats, and they are arranged oppositely in position.

[0017] Further, the jacks are arranged in a circumferential gap on the outer wall of the drive shaft.

[0018] The beneficial effects of the present utility model are as follows:

[0019] The present utility model uses the clamping mechanism, which can significantly reduce the steps and time for disassembling and assembling the rotor, improve the work efficiency. The operator only needs to perform simple operations to complete the fixation or disassembly of the rotor, without using tools such as socket wrenches, reducing the complexity of the operation.

[0020] In the traditional bolt fixation method, there may be a risk of loosening or falling off during high-speed rotation. The clamping mechanism reduces this risk through a more secure fixation method, which helps to protect the stability and operation safety of the centrifuge and reduces the safety hazards to the operator and experimental equipment.

[0029] A plug rod 4 is inserted into the long hole 2. A top seat 5 is provided at the top end of the outer wall of the plug rod 4 and is embedded in the groove 3. A plurality of through holes are penetrated through the outer wall of the top seat 5. A plurality of clamping mechanisms are inserted on the outer wall of the plug rod 4;

[0030] It further includes a drive shaft 10. A plurality of jacks 11 are penetrated through the outer wall of the drive shaft 10. A second spring 12 is provided on the inner bottom wall of the drive shaft 10. A scraper 13 is provided on the top end wall of the second spring 12. A connecting rod 14 is provided in the middle of the top end of the scraper 13. The top end of the connecting rod 14 extends out of the drive shaft 10 and is provided with a round block 15.

[0031] Further, the clamping mechanism includes a socket 6. A first spring 7 is provided on the inner side wall of the outer side of the socket 6. A spring seat 8 is provided on the inner end wall of the first spring 7. A plug block 9 is provided on the inner side wall of the spring seat 8. The inner end of the plug block 9 extends into the plug rod 4. The rotor 1 is sleeved on the drive shaft 10 from top to bottom. The lower end surface of the inner end of the plug block 9 contacts the top end of the drive shaft 10 and is pressed by the drive shaft 10 into the socket 6 to compress the first spring 7. When the rotor 1 moves downward on the outer wall of the drive shaft 10 to make the plug block 9 opposite to the jack 11, the spring seat 8 and the plug block 9 are pushed by the first spring 7 to move outward into the jack 11, so as to fixedly install the rotor 1 on the outer wall of the drive shaft 10.

[0032] Further, both the upper and lower ends of the inner wall surface of the insertion block 9 are designed with inclined slopes. When the round block 15 is lifted upward, the round block 15 drives the connecting rod 14 and the scraping plate 13 to move upward, and the second spring 12 is stretched. When the scraping plate 13 moves upward, it contacts the lower end surface of the insertion block 9, facilitating the extrusion of the insertion block 9 from the insertion hole 11.

[0033] Further, the number of grooves 3 is equal to that of the top seats 5, and their positions are arranged oppositely. The insertion rod 4 is inserted into the long hole 2, and the top seat 5 is embedded in the groove 3. The insertion rod 4 and the top seat 5 are installed in the long hole 2 and the groove 3 by passing a bolt through the through hole and tightening it in the threaded hole.

[0034] Further, the insertion holes 11 are arranged in a circumferential gap on the outer wall of the drive shaft 10. The rotor 1 is sleeved on the drive shaft 10 from top to bottom. The lower end surface of the inner side of the insertion block 9 contacts the top end of the drive shaft 10 and is pressed by the drive shaft 10 into the socket 6 to compress the first spring 7. When the rotor 1 moves downward on the outer wall of the drive shaft 10 and the insertion block 9 is opposite to the insertion hole 11, the first spring 7 pushes the spring seat 8 and the insertion block 9 to move outward into the insertion hole 11.

[0035] The detailed connection means are well-known techniques in the art. All components in this solution are common standard parts or components known to those skilled in the art. Their structures and principles can be known by those skilled in the art through technical manuals or by conventional experimental methods.

[0036] A specific application of this embodiment is as follows:

[0037] During use, the insertion rod 4 is inserted into the long hole 2, and the top seat 5 is embedded in the groove 3. The insertion rod 4 and the top seat 5 are installed in the long hole 2 and the groove 3 by passing a bolt through the through hole and tightening it in the threaded hole.

[0038] The rotor 1 is sleeved on the drive shaft 10 from top to bottom. The lower end surface of the inner side of the insertion block 9 contacts the top end of the drive shaft 10 and is pressed by the drive shaft 10 into the socket 6 to compress the first spring 7. When the rotor 1 moves downward on the outer wall of the drive shaft 10 and the insertion block 9 is opposite to the insertion hole 11, the first spring 7 pushes the spring seat 8 and the insertion block 9 to move outward into the insertion hole 11, thereby fixedly installing the rotor 1 on the outer wall of the drive shaft 10.

[0039] When the rotor 1 needs to be disassembled, the round block 15 is lifted upward, causing the round block 15 to drive the connecting rod 14 and the scraping plate 13 to move upward, and the second spring 12 is stretched. When the scraping plate 13 moves upward, it contacts the lower end surface of the insertion block 9 and extrudes the insertion block 9 from the insertion hole 11. The rotor 1 is lifted upward to remove the rotor 1 from the outer wall of the drive shaft 10, completing the disassembly of the rotor 1.

[0040] Certainly, the above description is not a limitation to the present utility model, nor is the present utility model limited to the above examples. Any changes, alterations, additions or substitutions made by those of ordinary skill in the art within the scope of the essence of the present utility model shall fall within the protection scope of the present utility model.
