Detailed description of the invention
Referring to figs. 1 through Fig. 6, embodiment of the present utility model is described further.
As shown in Figure 4 and Figure 5, in embodiment one, a kind of centrifuge, comprise the upper bracket 1 being placed with centrifugal barrel and the lower carriage 2 being placed with motor, the bottom of upper bracket 1 is fixedly connected with the metallic rod that section is L-type, metallic rod is lever 5, the bottom of metallic rod is fixedly connected with the first elastic device 3, first elastic device 3 comprises the first elastic component 32 and the first fixture 32, first elastic component 32 is elastic ring, elastic ring is made up of elastic caoutchouc, elastic caoutchouc has stronger elasticity, therefore after elastic caoutchouc is subject to having the vibration force of frequency, can play and reduce the frequency of vibration and the effect of amplitude, therefore the first elastic component 32 can reduce vibration force when centrifuge works preferably, lower carriage 2 is protruding upward simultaneously a boss 21, one end of lever 5 is fixedly connected with upper bracket 1, the first fixture 32 is equipped with in first elastic component 32, first fixture 32 is bolt, bolt is by lever 5, first elastic component 32 is fixedly connected with the boss 21 on lower carriage 2, fixed form can for offer the screwed hole 411 coordinated with bolt on lever 5 and lower carriage 2, also can be fixed by the cooperation of bolt and nut, such combination makes the fixing more stable of the first elastic component 32, lever 5 is provided with the second elastic device 4 away from one end of upper bracket 1 simultaneously, second elastic device 4 comprises vertical bar 41, second elastic component 45 and the second fixture 46, second elastic component 45 is elastic ring, second fixture 46 is bolt, vertical bar 41 is arranged on lower carriage 2, second elastic component 45 is arranged on the top of one end of lever 5 principle upper bracket 1 simultaneously, bolt is fed through elastic ring and is fixedly connected with vertical bar 41 with after lever 5, when upper bracket 1 is by gravity and vibration, gravity acts on lower carriage 2 by the first elastic device 3 and the second elastic device 4 simultaneously, first elastic device 3 and the second elastic device 4 serve the effect of dissipation of ferees, elastic ring is prevented to be subject to excessive gravity and to destroy, active force during centrifuge work simultaneously makes lever 5 vibrate, the first elastic component 32 and the second elastic component 45 that are separately positioned on lever about 5 both sides serve the effect reducing vibration, first elastic component 32 pairs lever 5 upwards acts on the effect serving buffering, the downward vibration of second elastic component 45 pairs lever 5 serves the effect of buffering.
As Fig. 1, shown in Fig. 2 and Fig. 3, in embodiment two, be with the difference technical characteristic of embodiment one, in embodiment two, lever 5 is provided with the 3rd elastic device away from the position of upper bracket 1, described 3rd elastic device comprises vertical bar 41, 3rd elastic component 42, dynamic mount 43, 3rd fixture, vertical bar 41 is fixedly connected with lower carriage 2, dynamic mount 43 for longitudinal section be hollow, lever 5 and dynamic mount 43 are fixed by bolts and nuts, 3rd fixture is fed through the 3rd elastic component 42 successively, dynamic mount 43 and vertical bar 41, 3rd elastic component 42, dynamic mount 43 is fixedly connected with by the 3rd fixture with vertical bar 41, wherein the 3rd fixture is bolt or steady pin, 3rd elastic component 42 is elastic ring, fixed bar offers screwed hole 411, as shown in Figure 6, spring 412 is provided with in screwed hole 411, one end of spring 412 abuts with the bottom of screwed hole 411, the other end of spring 412 abuts with steady pin, spring 412 pairs of steady pins serve the effect of damping, simultaneously when centrifuge uses, centrifugal barrel and motor all can vibrate, but both vibrations may cause the effect of resonating, but upper bracket 1 only has the first elastic device 3 and the second elastic device 4 with the link position of lower carriage 2, first elastic device 3 pairs centrifugal barrel serves the effect of buffering, second elastic device 4 pairs motor serves buffering to the vibration force of lever 5 and reduces the effect of vibration, simultaneously, be provided with micro-burst motor in second elastic component 4, namely the second elastic component 4 has wrapped micro-burst motor, and micro-burst motor makes the second elastic component 4 produce vibration, thus there is situation about resonating in the upper bracket 1 avoiding centrifuge and lower carriage 2, protects the mechanical performance of centrifuge.
