Description

Electronic balance

Technical field

The utility model relates to the projection electronic weighing field, relates in particular to a kind of electronic balance.

Background technology

Electronic balance is a kind of metering outfit of precision.Existing electronic balance comprise no outer cover with two kinds that outer cover is arranged, wherein have the outer cover of the electronic balance of outer cover to be fixed on the top of electronic balance, its top and both sides are provided with sliding door conveniently to take by weighing sample.

This of the prior artly have the electronic balance of outer cover to exist following deficiency: when weighing can not be put into the object of fixed day plain bonnet fully, because sliding door can not shut fully, so object will be exposed under the outside air.Owing to reasons such as air humidity and air-flows, can cause the instability of weighing and inaccurate, and the precision of balance is high more, this phenomenon is just obvious more.For example, on the balance of 0.0001g precision during weighing, the data drift can be to 0.001g even more, thereby it is impossible that accurate weighing is become.This situation is comparatively common in work such as analyzing and testing.

In addition, for the electronic balance that outer cover is arranged of the prior art, its outer cover is fixed on the top of electronic balance.Inconvenient in the long-time cleaning of back outer cover of using, the visibility when influencing accuracy and the weighing of weighing.

The utility model content

For solving the aforementioned problems in the prior, the utility model provides a kind of separated electronic balance of being convenient to operate that adapts to various weighing environment and accuracy requirement.

According to the utility model a kind of electronic balance is provided, it comprises base, and is removably mounted on the outer cover on the base with the mode of integral body.

According to this design, outer cover is removably mounted on the base with the mode of integral body, makes outer cover integrally to disassemble from base, is convenient to clean.

According to an embodiment, this electronic balance also comprises inner cover.Inner cover is removably mounted on the base with the mode of integral body, and is within the outer cover.Through the structure of this double casing, can make this electronic balance adapt to different weighing demands, hour be placed in the inner cover at weighed object, and when weighed object is big, remove inner cover and be placed in the outer cover.

In one example, outer cover and inner cover are installed on the base through draw-in groove cooperation or threaded engagement.Preferably, in outer cover and inner cover, all sliding door can be set.

In another example, in outer cover and/or inner cover, be provided with the part that is used to hold drying agent, wherein the part of holding drying agent has the bigger volume of part that is used to hold drying agent than inner cover being used in the outer cover.This part that is used for holding drying agent for example can be the groove of base.

In another example, base is arranged to have step, and wherein inner cover is installed on the higher step face of base, and outer cover is installed on the low step surface of base.

The utility model can bring following beneficial effect.For example, owing to the mode of day plain bonnet with integral body removably is fixed on the base, therefore a day plain bonnet is convenient to dismounting, is easy to cleaning.Adopt the structure of double casing can adapt to different weighing demands, when the less and accuracy requirement of alleged object was very high, the double-deck sky plain bonnet with inner cover and outer cover can prevent the coarse problem of measurement that sliding door is not closed completely and is brought effectively.When the big and accuracy requirement of alleged object is high, can not remove inner cover and outer cover only is installed.In addition, the drying agent holding portion in outer cover and the inner cover can guarantee further that the humidity of measurement environment keeps constant.
