[0002] Centrifuges vibrate significantly during operation, primarily in a radial spiral motion. However, conventional centrifuge anti-vibration bases provide axial vibration protection. Consequently, when subjected to radial vibration, the buffer springs in these bases are prone to fatigue, reducing their cushioning performance and shortening their lifespan. Furthermore, the buffer springs can easily impact the inner wall of the base during twisting, generating collision noise. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1-3 The centrifuge base shown includes a placement base 1 and guide sleeves 2 disposed on the upper end of the placement base 1 and located at the four corners of the placement base 1. Each guide sleeve 2 has a buffer spring 5 installed inside. Each guide sleeve 2 has a guide post 3 installed inside and above the buffer spring 5. The upper end of each guide post 3 is fixedly connected to a shockproof base 4. The shockproof base 4 is directly opposite the placement base 1. The two ends of the buffer spring 5 are fixedly connected to the placement base 1 and the guide post 3 respectively.

[0017] The guide sleeve 2 and the guide post 3 are coaxially arranged, and the inner diameter of the guide sleeve 2 is larger than the outer diameter of the guide post 3, so as to avoid the guide post 3 and the guide sleeve 2 colliding and causing noise due to the torsion of the buffer spring 5; A buffer pad 6 is installed between the placement base 1 and the shockproof base 4. The buffer pad 6 is located at the center of the shockproof base 4, and the upper and lower ends of the buffer pad 6 are fixedly connected to the placement base 1 and the shockproof base 4, respectively.

[0018] like Figure 3 As shown, the cushioning pad 6 includes an elastic shell 601 made of rubber. Rigid support layers 602 and elastic cushioning layers 603 are stacked at intervals inside the elastic shell 601. The bottom and top of the elastic shell 601 are bonded to the rigid support layers 602, and the elastic cushioning layers 603 are connected to the rigid support layers 602 on both sides. The elastic buffer layer 603 can be elastically deformed laterally.

[0019] In this embodiment, a large number of blind holes 604 are evenly distributed on the surface of the rigid support layer 602. The elastic buffer layer 603 has protrusions 605 that are adapted to each blind hole 604 on both sides. The inner top and inner bottom surfaces of the elastic shell 601 are also provided with protrusions 605 that are adapted to each blind hole 604. The protrusions 605 are embedded in the corresponding blind holes 604.

[0020] The connection stability between the rigid support layer 602 and the elastic buffer layer 603 is increased by the interlocking of the blind hole 604 and the protrusion 605, thus avoiding relative sliding displacement between the rigid support layer 602 and the elastic buffer layer 603.

[0021] The present invention further includes a plurality of matrix-arranged through holes 606 on the rigid support layer 602, and a connecting body 607 extending into the through holes 606 on the elastic buffer layers 603 on both sides of the rigid support layer 602. The elastic buffer layers 603 on both sides of the rigid support layer 602 are connected to each other through the connecting body 607. The inner top surface and inner bottom surface of the elastic shell 601 are also provided with connecting bodies 607 extending into the through holes 606, and the elastic shell 601 is connected to the inner elastic buffer layer 603 through the connecting body 607.

[0022] The connector 607 connects all the elastic buffer layers 603 into a whole, improving the overall buffering performance of the buffer pad 6 and preventing the individual elastic buffer layers 603 from becoming misaligned due to the radial vibration of the centrifuge.

[0023] The rigid support layer 602 is a steel plate, and the elastic buffer layer 603 is a rubber plate, preferably a lightweight rubber plate.

[0024] like Figure 2 As shown, the opposing surfaces of the base 1 and the shockproof base 4 are respectively provided with slots 7 that are adapted to the buffer pad 6. The upper and lower ends of the buffer pad 6 are respectively embedded in the slots 7, and the depth of the slots 7 is such that at least one rigid support layer 602 is located in the slots 7.

[0025] The use of slot 7 to insert the buffer pad 6 ensures that the radial vibration of the centrifuge acting on the shockproof base 4 can be completely transmitted to the buffer pad 6.

[0026] like Figure 3 As shown, multiple outwardly extending screws 608 are vertically fixed to the opposite surfaces of the rigid support layers 602 located at the top and bottom layers. The placement base 1 and the shock-absorbing base 4 are each provided with countersunk holes 8 corresponding to the screws 608. Nuts 609 that are threadedly connected to the screws 608 are provided in the countersunk holes 8. The buffer pad 6 is reliably connected to the placement base 1 and the shock-absorbing base 4 through the screws 608 and the nuts 609.

[0027] In this embodiment, the centrifuge is placed on the anti-vibration base 4 and fixedly connected to the anti-vibration base 4. The radial vibration generated during the use of the centrifuge is transmitted to the buffer pad 6 through the anti-vibration base 4. The elastic buffer layers in the buffer pad 6 undergo radial deformation to absorb and reduce the vibration, thereby suppressing the radial vibration amplitude of the centrifuge, improving the working stability of the centrifuge, and at the same time reducing the torsional amplitude of the buffer spring 5, extending the service life of the buffer spring 5, and avoiding the buffer spring 5 or the guide post 3 from hitting the guide sleeve 2 to generate collision noise, thus achieving the function of shock absorption and noise reduction.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
