Abstract
The utility model relates to a two-stage damping structure for a table centrifuge, which comprises upper damping feet, lower damping feet and a transition disk, wherein a fixator is arranged at the upper ends of the upper damping feet; the fixator is arranged on the outer side of a motor of the table centrifuge; the lower ends of the lower damping feet are arranged on the ground by support pillars; the transition disk is connected with the lower ends of the upper damping feet and the upper ends of the lower damping feet; a plurality of upper damping feet and a plurality of lower damping feet are provided and are uniformly distributed. The two-stage damping structure for the table centrifuge, which is disclosed by the utility model, uses double layers of damping feet; two layers of damping feet are connected by the transition disk; the joints of the damping feet and a motor are changed into the upper part of the motor from the conventional bottom of the motor and are closer to the position of a rotor (a vibrating source), so that the difference of physical performance between rubber parts of the damping feet can be effectively balanced, the aging difference between the rubber parts can be alleviated, and vibration and noise are effectively reduced.
Description
Technical field
The utility model relates to a kind of secondary shock-damping structure for table top centrifuge.
Background technique
In general, table top centrifuge basic functional principle is to drive carrying to treat that the rotor of centrifugal sample carries out High Rotation Speed by motor.In this process, owing to existing the rotor that in inevitable trueness error and each container, example weight difference causes stressed asymmetric in the part processing of machine own and assembling, all can cause vibrations in various degree in machine operation procedure.Excessive vibrations are not only unfavorable to the centrifuge life-span itself, and the excessive noise that vibrations produce also can cause harmful effect to surrounding enviroment, and the vibrations that exceed to a certain degree even can cause security threat to user.
Present stage is between drive motor and supporting element, to add one group of rubber shock-absorbing pin to the main shock absorbing means of medical centrifuge, can effectively absorb most vibrations, plays good damping effect.But because the physical properties such as damping constant, hardness, elasticity between each rubber parts of every group of shock-absorbing foot there are differences unavoidably, add the difference of long-term use degree of aging afterwards etc., cause the undesirable of damping effect.
Model utility content
The purpose of this utility model is to provide a kind of table top centrifuge secondary shock-damping structure that improves damping effect.
For solving the problems of the technologies described above, the utility model table top centrifuge secondary shock-damping structure, comprising: upper shock-absorbing foot, and the upper end of shock-absorbing foot is provided with fixture on described, and described fixture is arranged on the motor outside of table top centrifuge; Lower shock-absorbing foot, the lower end of described lower shock-absorbing foot arranges on the ground by supporting post; Transition disc, described transition disc connects the lower end of described upper shock-absorbing foot and the upper end of described lower shock-absorbing foot.
The quantity of described upper shock-absorbing foot and described lower shock-absorbing foot is multiple.Multiple described upper shock-absorbing foots and described lower shock-absorbing foot are for being uniformly distributed.
The utility model table top centrifuge secondary shock-damping structure uses double-layer shock-absorbing pin, between two-layer, connect with transition disc, and the connection part of shock-absorbing foot and motor is made into the top of motor by traditional motor bottom, the position of more close rotor (vibratory source), the difference of the physical property between the rubber parts of the each shock-absorbing foot of balance effectively, and aging difference between mitigation rubber parts, effectively reduce vibrations and noise.

Embodiment
Below in conjunction with accompanying drawing, the utility model table top centrifuge secondary shock-damping structure is described in further detail.
As shown in Figure 1, the utility model table top centrifuge secondary shock-damping structure, comprising: multiple equally distributed upper shock-absorbing foots 1, be provided with fixture 2 in the upper end of upper shock-absorbing foot 1, and fixture 2 is arranged on motor 3 outsides of table top centrifuge; Multiple equally distributed lower shock-absorbing foots 4, the lower end of lower shock-absorbing foot 4 arranges on the ground by supporting post 5; Transition disc 6, transition disc 6 connects the upper lower end of shock-absorbing foot 1 and the upper end of lower shock-absorbing foot 4.
The utility model table top centrifuge secondary shock-damping structure uses double-layer shock-absorbing pin, between two-layer, connect with transition disc, and the connection part of shock-absorbing foot and motor is made into the top of motor by traditional motor bottom, the position of more close rotor (vibratory source), the difference of the physical property between the rubber parts of the each shock-absorbing foot of balance effectively, and aging difference between mitigation rubber parts, effectively reduce vibrations and noise.
Below the preferred embodiment of the utility model having been created illustrates, but the utility model is created and is not limited to embodiment, those of ordinary skill in the art also can make all modification being equal to or replacement under the prerequisite without prejudice to the utility model creative spirit, and the modification that these are equal to or replacement are all included in the application's claim limited range.
