Description

The centrifuge interlock

Technical field

The utility model relates to the Centrifuge Techniques field, and particularly centrifuge locking system technical field specifically refers to a kind of centrifuge interlock.

Background technology

As medical institutions suspension is carried out the centrifuge that precipitate and separate is used, original centrifuge does not have interlock or is complicated frame for movement interlocking, and cost is high, complex operation, poor reliability.

See also shown in Figure 1ly, centrifuge has aluminium cover 1 and cover plate 2, and cover plate 2 has cover plate handle 21, centrifuge operation or when stopping, cover plate 2 can arbitrarily be laid or remove on aluminium cover 1 by cover plate handle 21.Although easy and simple to handle, with low cost.But do not meet medical industry security appliance standard, when centrifuge moved, what cover plate 2 can be unrestricted arbitrarily opened, all dangerous to the liquid and the operating personnel that separate, can cause security incident.

In order to improve the security of centrifuge, centrifuge with locking system has appearred, see also shown in Figure 2, steady brace 3 on cover plate 2, pull bar 3 one ends are coupling in the first cover plate seat 31, and when cover plate 2 covered on aluminium cover 1, the other end of pull bar 3 was that pull bar hook 32 enters the jump ring card 35 that hooks in the pull bar hook placed hole 34 of the second cover plate seat 33 inside, pull bar 3 is pressed power switch 36 simultaneously, and centrifuge brings into operation; Otherwise, when pull bar hook 32 being opened by specific purpose tool handle hole 37 by specific purpose tool, lifting pull bar 3, the button of power switch 36 is upspring, and centrifuge is out of service.Although meet medical industry security appliance standard, when cover plate 2 covers on aluminium cover 1, be not easy arbitrarily to be removed, to the equal safety of the liquid that separates and operating personnel.But material cost, the assembling labour cost high; In addition, although compared to Figure 1, during the machine operation, cover plate 2 can arbitrarily not opened, still, in case the impaired inefficacy of specific purpose tool (as: key etc.) or jump ring card 35 are malfunctioning stuck, cover plate 2 just can't be opened, separating liquid can't continue to use in the centrifuge, if the normal time does not open, separating liquid has the risk of damaging or wasting.

Therefore, need to provide a kind of centrifuge locking system, it is simple for structure, and is easy and simple to handle, safe and reliable, and reduces the labour cost of material cost and assembling.
