Abstract

The utility model provides a kind of hairbrush for balance on goods and services dedusting, is made up of bristle and quadrangular.Bristle is cemented on quadrangular, and quadrangular has pit.The utility model utilizes consolidation hairbrush on quadrangular, hairbrush is couched or does not on end contact with experimental bench, and keep flat after avoiding hairbrush to use and cause pickup, what be conducive to balance accurately carries out material weighing.

Description

A kind of hairbrush for balance on goods and services dedusting

Technical field

The utility model belongs to a kind of instrument and equipment, specifically a kind of hairbrush for balance on goods and services dedusting.

Background technology

Balance is a kind of weighing apparatus, props up balance beam and forms two arms, each arm is hung a dish by fulcrum (axle) at the center of beam, and the deflection of pointer when not swinging and point to center scale be fixed on beam just indicates the quality of object under test.Balance is a kind of bascule, is the instrument weighing mass of object.The type of present balance is a lot, but no matter is counter balance or electronic balance, is all must remove any material in weighing plate and balance weighing room with banister brush in use, keeps weighing indoor cleaning.Even if otherwise residual a small amount of dust or impurity also can affect the accuracy of weighing, cause the evaluated error of object.Current normally used balance hairbrush is conventional straight post, and a termination bristle, uses and just lie on experimental bench, easy pickup bristle.Although this instrument has used for many years, as a kind of operating process of experiment, use this general utility balance hairbrush or not perfect ideal, be mainly manifested in following several respects:

1. experiment preferably has instrumentation.Learning science knowledge be unable to do without experiment, and particularly chemical experiment all be unable to do without laboratory apparatus.Some schools have configured the experimental implementation case of staff one, are furnished with various simple laboratory apparatus in case, create necessary condition for student does yourself to test.In weighing experiment, balance hairbrush is also a kind of specific purpose tool, is preferably finished to cross to be kept at standby in experimental box preservation.

2. in experimental implementation process, when carrying out weighing front, first balance brush cleaning pallet and inside, balance weighing room is used, rear hairbrush is used to keep flat experimental bench, easy pickup bristle, clean pallet when being unfavorable for that second time weighs, often occur that balance on goods and services does not totally cause the weighing error that material is small in an experiment.

Summary of the invention

For the weak point of existing general utility balance hairbrush, the purpose of this utility model is to provide a kind of hairbrush for balance on goods and services dedusting.

The purpose of this utility model can be realized by following measures:

For a hairbrush for balance on goods and services dedusting, be made up of bristle and quadrangular, it is characterized in that bristle is cemented on quadrangular, quadrangular has pit.

The beneficial effect of advantage of the present utility model and generation is:

1, the utility model utilizes consolidation hairbrush on quadrangular, hairbrush is couched or does not on end contact with experimental bench, keeps flat and causes pickup, be conducive to the weighing that balance carries out material exactly after avoiding hairbrush to use.

2, quadrangular there is pit, be convenient to finger and put in pit and to hold steadily quadrangular, remove the dust on weighing plate with the hairbrush on quadrangular.

3, the utility model structure is simple, simple for production, cheap, and clean balance on goods and services is safe and reliable, simple and convenient.As special equipment during clean balance on goods and services, be configured in each laboratory, for experimental implementation is provided convenience.

Accompanying drawing explanation

Fig. 1 is the utility model schematic diagram.

Detailed description of the invention

Below in conjunction with accompanying drawing, then the utility model is described in further detail:

As shown in Figure 1, a kind of hairbrush for balance on goods and services dedusting, is made up of bristle 1 and quadrangular 2, and bristle 1 is cemented on quadrangular 2, quadrangular 2 has pit 3.

Balance weighs article, and during clean balance on goods and services, finger puts in pit 3 and to hold steadily quadrangular 2, removes the dust on weighing plate with the hairbrush 1 on quadrangular 2.

Quadrangular 2 can be erect or couch on experimental bench after using, hairbrush 1 does not contact with experimental bench, and whole operating process is fast steady, safe and reliable, causes pickup, be conducive to the accurate weighing of balance after avoiding hairbrush 1 to use.

Claims

1. for a hairbrush for balance on goods and services dedusting, be made up of bristle (1) and quadrangular (2), it is characterized in that bristle (1) is cemented on quadrangular (2), quadrangular (2) has pit (3).
