Description

Closed type use for laboratory solia particle is taken spoon

Technical field

The present invention relates to laboratory trace solid and take spoon, especially closed type laboratory trace solid is taken spoon, is mainly used in laboratory pre-treatment and takes trace solid.

Background technology

Spoon is the instrument of the solid reagent for taking Powdered or fine granularity.Most of spoon only has a spoon, and respectively there is a spoon at some spoon two, and spoon is made up of metal, ox horn or plastics conventionally.Due to its specific use, and be widely used in laboratory and hospital pharmacy.In the pre-treatment of laboratory, take the mode that trace solid often takes hand to tremble with spoon, due to the state difference of trace solid, easily unrestrained or stick to vessel port place while taking.The waste so causing is very common in laboratory.Therefore, how guaranteeing that solia particle can not waste in the time that spoon takes trace solid, is urgent problem.

Summary of the invention

The object of the invention is to take waste for laboratory solia particle, provide a kind of laboratory solia particle that can effectively avoid laboratory solia particle to take waste simple to operate to take spoon.

The technical scheme that technical solution problem of the present invention is taked is:

The present invention is made up of stainless steel, total length is 100～110mm, the Design of length of 100～110mm can be taken solia particle in the solids container of various different size, and this spoon comprises spoon head, lever, covering plate, spring, snak link, handspike, sliding pawl cover, calibration pawl and calibration rotating cylinder.

Described spoon head is positioned at spoon entirety foremost, is a recessed spoon, long 13～15mm, and the widest part is 7.0～7.5mm, the needs that the little design of recessed spoon essence is taken in order to meet trace solid, and contribute to covering plate propelling movement to hide.

Long 68～the 70mm of described lever, wide 3.0～4.0mm, thick 1.6～2.0mm, the flat strip design of lever entirety is convenient to capture take and is held; Termination spoon head before lever, inside is cylindrical cavity.

Described covering plate is positioned at handspike foremost, and shape and spoon head match, long 14～16mm, and the widest part is 7.5～8.0mm, in order to hide spoon head.

Described handspike is contained in cylindrical cavity, and its height is 60～63mm, the cylinder that disc diameter is 1.2～1.5mm, and front end connects covering plate, and end is enclosed within sliding pawl cover.

Described snak link, apart from lever front end 11～12mm place, is the oval small embossment in handspike both sides one, and the widest part is 0.7～0.9mm.

Described spring is stainless steel spring, and length is 12～13mm, is placed on snak link between covering plate.

Described sliding pawl cover is made by elastic resin with calibration rotating cylinder, and sliding pawl cover is enclosed within handspike top, and calibration rotating cylinder is enclosed within sliding pawl and puts.

Beneficial effect of the present invention:

1. spoon overall length 100～110mm, the Design of length of 100～110mm can be taken reagent in the solids container of various different size; The design of covering plate guarantee spoon pipette in process, can not trickle down or insert container in can not stick to vessel port.

2. handspike is placed in to spoon lever inner chamber and is equipped with spring, sliding pawl, the design of calibration rotating cylinder, has not only kept original model in appearance, has also guaranteed that handspike can effectively be fixed on lever inner chamber simultaneously.

3. press calibration rotating cylinder, the compression of handspike Compress Spring, covering plate stretches out concordant with spoon head simultaneously, hide spoon head, reach the effect that spoon closure prevents that solia particle is unrestrained, fundamentally having solved trace solid solia particle unrestrained and that cause in the time using spoon to take trace solid wastes or data deviation.

Accompanying drawing explanation

Fig. 1 is the structure chart of spoon of the present invention.

The specific embodiment

In order to describe technology contents of the present invention and structural feature in detail, below in conjunction with embodiment and coordinate accompanying drawing to be described further.

As shown in Figure 1, closed type use for laboratory solia particle is taken spoon and is comprised spoon head 10, lever 6, covering plate 9, spring 8, snak link 7, handspike 5, sliding pawl cover 4, sliding pawl 3, calibration pawl 2 and calibration rotating cylinder 1.Spoon one stainless steel is made, and total length is 100～110mm, and the Design of length of 100～110mm can be taken solia particle in the solids container of various different size.Spoon head is positioned at spoon entirety foremost, is the recessed spoon of a pyriform, long 13～15mm, and the widest part is 7.0～7.5mm, the needs that the little design of recessed spoon essence is taken in order to meet trace solid, and contribute to covering plate propelling movement to hide.Long 68～the 70mm of lever, wide 3.0～4.0mm, thick 1.6～2.0mm, and the flat strip design of lever entirety is convenient to capture by holding; Termination spoon head before lever, inside has cylindrical cavity.Covering plate is positioned at handspike foremost, is a pyriform plane, long 14～16mm, and the widest part is 7.5～8.0mm, the design of pyriform plane is in order to hide the recessed spoon of pyriform.Handspike is high 60～63mm, the cylinder of disc diameter 1.2～1.5mm, and front end connects covering plate, and end is enclosed within a sliding pawl cover.Spring is stainless steel spring, and length is 12～13mm.Snak link, apart from lever front end 11～12mm place, is the oval small embossment in handspike both sides one, and the widest part is 0.7～0.9mm.Sliding pawl cover is made by elastic resin with calibration rotating cylinder, and sliding pawl cover is enclosed within handspike top, and calibration rotating cylinder is enclosed within sliding pawl and puts, between the two by coordinating between sliding pawl and calibration pawl.

Use procedure of the present invention: take in advance about 0.2500g laver powder standard items.

Take before laver powder standard items, first water cleans spoon head and covering plate, and pure water washes down, and then paper using is wiped clean spoon, observes covering plate and whether is positioned at original position.If not in original position, press calibration rotating cylinder covering plate is promoted to original position.Then the container bottle that holds laver powder is opened, observed and whether have enough amounts; Then spoon is stretched in container bottle, take required amount; Then applying light calibration rotating cylinder, makes covering plate cover spoon head.Spoon is moved on in counteracting tank again, press calibration rotating cylinder, pack up covering plate, shake, slowly pours the laver powder in spoon into, until 0.2500g slightly.After having taken, if also have laver powder in spoon, residual laver powder is put into and specified in returnable, finally spoon paper using is wiped clean, press calibration rotating cylinder and make covering plate get back to original position.

Above disclosed is only preferred embodiment of the present invention, the interest field that certainly can not limit the present invention with this, and the equivalent variations of therefore doing according to the claims in the present invention, still belongs to the scope that the present invention is contained.
