Technical Field

[0001] This utility model relates to the field of low-speed centrifuge technology, specifically to a base stabilization structure for a low-speed centrifuge. Background Technology

[0002] Low-speed centrifuges have wide applications in medical, scientific research, and other fields. However, existing low-speed centrifuge base structures have many problems. On the one hand, traditional bases are inadequate in shock absorption, and the vibrations generated during centrifuge operation cannot be effectively absorbed. This not only leads to unstable centrifuge operation but also interferes with surrounding equipment and personnel. On the other hand, there are defects in the anti-slip design, making the centrifuge prone to displacement during operation, affecting its normal operation and shortening its service life.

[0008] A further improvement of this utility model is that the inclined buffer spring is located on one side of the transverse damping rod, and one end of the inclined buffer spring is fixedly connected to one side of the positioning block.

[0009] A further improvement of this utility model is that the number of supporting slide plates is two sets, and the two sets of supporting slide plates are symmetrically distributed on the upper surface of the supporting base plate.

[0021] The present invention will be further described in detail below with reference to embodiments:

[0022] Example 1

[0023] like Figures 1-4 As shown, this utility model provides a base stabilization structure for a low-speed centrifuge, including a low-speed centrifuge housing 1. A stabilization component is provided on the bottom surface of the low-speed centrifuge housing 1. The stabilization component includes a support seat 2. A side connecting plate 4 is fixedly connected to one side of the support seat 2. A vertical damping rod 5 is fixedly connected to the bottom surface of the side connecting plate 4 near one end. A support slide plate 7 is fixedly connected to the bottom surface of the vertical damping rod 5. A rubber roller 8 is rotatably connected to the bottom surface of the support slide plate 7.

[0024] A transverse buffer assembly is provided on one side of the supporting slide plate 7. The bottom surface of the rubber roller 8 is movably connected to the supporting base plate 3. A vertical buffer spring 6 is sleeved on the outer wall near the top. The top of the vertical buffer spring 6 is fixed to the bottom surface of the side connecting plate 4 near one end. An L-shaped side plate 9 is fixedly connected to one side of the supporting base plate 3. A side buffer spring 10 is fixedly connected to the side of the L-shaped side plate 9 near the top. The end of the side buffer spring 10 away from the L-shaped side plate 9 is fixedly connected to the outer wall of the receiving seat 2.

[0025] The lateral buffer assembly includes an inclined buffer spring 12 and a lateral damping rod 13. One end of the lateral damping rod 13 is rotatably connected to the center of one side of the support slide plate 7, and the end of the lateral damping rod 13 away from the support slide plate 7 is rotatably connected to a positioning block 11. The bottom surface of the positioning block 11 is fixedly connected to the upper surface of the support base plate 3.

[0026] Example 2

[0027] like Figures 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the oblique buffer spring 12 is located on one side of the transverse damping rod 13, and one end of the oblique buffer spring 12 is fixedly connected to one side of the positioning block 11.

[0028] There are two sets of supporting slide plates 7, which are symmetrically distributed on the upper surface of the supporting base plate 3.

[0029] A rubber gasket 14 is fixedly connected to the bottom of the inner wall of the receiving seat 2, and the inner wall of the receiving seat 2 is engaged with the outer wall of the low-speed centrifuge housing 1 near the bottom.

[0030] A threaded sleeve is fixedly connected to the bottom surface of the support base plate 3, and an adjusting foot 15 is threadedly connected to the inner wall of the threaded sleeve.

[0031] The vertical damping rod 5 is 200mm long, 20mm in diameter, and has a damping coefficient of 500 N·s / m; the horizontal damping rod 13 is 150mm long, 15mm in diameter, and has a damping coefficient of 300 N·s / m. These parameters effectively match the vibration frequency and force generated during low-speed centrifuge operation, thus maximizing the damping and buffering effect.

[0032] The inclined buffer spring 12 has a spring constant of 800 N / m and a maximum compression of 50 mm; the vertical buffer spring 6 has a spring constant of 1000 N / m and a maximum compression of 40 mm; and the lateral buffer spring 10 has a spring constant of 600 N / m and a maximum compression of 35 mm. These parameters are calculated based on the common vibration amplitude and impact force of low-speed centrifuges, and can provide stable buffer protection for centrifuges in different directions.

[0033] The support plate 7 and the rubber roller 8 are rotatably connected by a 10mm diameter pin, and deep groove ball bearings of model 6202 are installed at both ends of the pin. These bearings can withstand certain radial and axial loads and effectively reduce frictional resistance during rotation. The support plate 7 and the transverse damping rod 13 are connected by a rotary joint with a self-lubricating bushing. The bushing is made of polytetrafluoroethylene, which has good self-lubricating and wear-resistant properties, ensuring flexible and stable rotation and meeting the needs of long-term operation of the centrifuge.

[0034] The working principle of the base stabilization structure for this low-speed centrifuge will be explained in detail below.

[0035] like Figures 1-4 As shown, during use, the low-speed centrifuge housing 1 is connected to the receiving seat 2, and then the low-speed centrifuge housing 1 is placed on the receiving seat 2. When the vibration generated during the operation of the low-speed centrifuge housing 1 is transmitted to the receiving seat 2, the receiving seat 2 will compress or stretch the vertical damping rod 5 and the vertical buffer spring 6 through the side connecting plate 4, thus creating a vertical buffering effect. Meanwhile, the support slide plate 7 will move back and forth via the rubber roller 8 under the vibration of the side connecting plate 4. At this time, the transverse damping rod 13 and the oblique buffer spring 12 will be compressed or stretched, thereby buffering the vibration of the low-speed centrifuge housing 1 in the front-to-back direction.

[0036] Because the rubber rollers 8 are made of rubber, and in conjunction with the deformation-absorbing effect of the side-mounted buffer springs 10, when the low-speed centrifuge casing 1 experiences lateral vibration, the damping effect generated by the friction of the rubber rollers 8 and the deformation-absorbing effect of the side-mounted buffer springs 10 provide lateral cushioning. Therefore, it effectively reduces vibration and noise during the operation of the low-speed centrifuge casing 1, minimizing interference with surrounding equipment and personnel, and extending the service life of the centrifuge.

[0037] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
