Description

A kind of propelling movement type laboratory trace solid is taken spoon

Technical field

The utility model relates to laboratory trace solid and takes spoon, and especially propelling movement type laboratory trace solid is taken spoon, is mainly used in laboratory pre-treatment and takes trace solid.

Background technology

Spoon is for taking the instrument of the solid reagent of Powdered or fine granularity.Due to its specific use, and be widely used in laboratory and hospital pharmacy.In the pre-treatment of laboratory, though spoon can be taken the solid reagent of different size size, when taking the last fine setting of trace solid, easily application of sample is excessive, once and application of sample excessive, need all processes to restart, waste time and energy.Therefore, the required solid masses of precise fine-adjustment how when spoon takes trace solid, is urgent problem.

Summary of the invention

When the utility model takes trace solid for laboratory, lack the spoon that can effectively finely tune the solid amount of taking, provide a kind of laboratory trace solid of required solid masses that can effectively regulate to take spoon.

The technical scheme that the utility model technical solution problem is taked is:

The utility model is made by stainless steel, and its overall length is 75mm, comprises lever, spoon, pushes thick stick, pusher and turning handle.

Long 66～the 70mm of described lever, wide 2.8～3mm, thick 1.3～1.5mm, the whole flat strip of lever; Termination spoon before lever, end connects turning handle, and inside has cylindrical cavity, and the two ends that inside has cylindrical cavity are provided with trapezoidal internal thread.

Described propelling movement thick stick is high 66.5～70.5mm, the cylinder that disc diameter is 0.9～1.1mm, and front end connects pusher, and end connects turning handle, and the two ends that push thick stick are provided with trapezoidal external screw thread, match with the trapezoidal internal thread in cylindrical cavity.

Described spoon is positioned at spoon integral body foremost, is a recessed spoon, long 4.0～4.5mm, and the widest part is 3.6～4mm.

Described pusher is that diameter is the indent hemisphere of 2.4～2.6mm, recessed to towards advancing thick stick, and is positioned at the upper end of spoon, does not directly contact with spoon.

Described turning handle is high 4.0～4.5mm, disc diameter 2.8～3mm ratchet cylinder.

The utility model beneficial effect:

1. spoon overall length 74～79mm, the Design of length of 74～79mm can be taken reagent in the solids container of various different size; And give spoon and have fabulous stability and balance, guarantee that spoon can not trickle down reagent in pipetting process.

2. by the design that pushes thick stick and be placed in spoon lever inner chamber and join screw thread, not only keep in appearance original model, reduced the overall weight of spoon; Also guaranteed that propelling movement thick stick can effectively be fixed on lever inner chamber simultaneously.

3. rotation ratchet turning handle, finely tunes pusher, reaches the effect of the required solid masses of fine adjustments, has fundamentally solved the deviation that cannot effectively estimate required solid masses and cause when using spoon to take trace solid.

Accompanying drawing explanation

Fig. 2 is the front view of the utility model spoon.

The specific embodiment

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

As depicted in figs. 1 and 2, propelling movement type laboratory trace solid is taken spoon integral body and is made and formed by stainless steel, comprises lever 3, spoon 6, screw thread 2, pushes thick stick 4, pusher 5 and turning handle 1.Spoon overall length 75mm, the Design of length of 75mm can be taken reagent in the solids container of various different size; And give spoon and have fabulous stability and balance, guarantee that spoon can not trickle down reagent in pipetting process.Long 66～the 70mm of lever, wide 2.8～3mm, thick 1.3～1.5mm, and the whole flat strip design of lever is convenient to capture by holding; Termination spoon before lever, end connects turning handle, and inner tool cylindrical cavity is joined screw thread.Spoon is positioned at spoon integral body foremost, is the recessed spoon of a pyriform, long 4.0～4.5mm, and the widest part is 3.6～4mm, the needs that the little design of recessed spoon essence is taken in order to meet trace solid, and contribute to pusher to push.Screw thread is positioned at lever internal cavities two ends and pushes thick stick two ends, and internal cavities is trapezoidal internal thread, and pushing thick stick screw thread is trapezoidal external screw thread; Two screw threads are in contact with one another, in order to the fixing and mobile thick stick that pushes.Pushing thick stick is high 66.5～70.5mm, the cylinder that disc diameter is 0.9～1.1mm, and front end connects pusher, and end connects turning handle, is the unique hinge that connects pusher and turning handle.Pusher is that diameter is the indent hemisphere (advancing the junction of thick stick and pusher is indent) of 2.4～2.6mm, is positioned at the upper end of spoon, does not directly contact with spoon; With the trickle propelling solia particle of propeller, to reach the object of the required solid masses of fine adjustments.Turning handle is high 4.0～4.5mm, disc diameter 2.8～3mm ratchet cylinder, and the design of ratchet turning handle can not only increase holds sense, can also increase friction and be convenient to regulate rotation.

The utility model use procedure: the methyltestosterone standard items that take in advance 8mg.

Take before methyltestosterone standard items, first paper using is wiped clean spoon, observes pusher and whether is positioned at original position.If not in original position, rotate turning handle pusher is promoted to original position.Then the container bottle that holds methyltestosterone is opened, observed and whether have enough amounts; Take afterwards spoon to stretch in container bottle, take required amount.Again spoon is moved on on pan paper, slightly rotate turning handle, advance pusher, the methyltestosterone in spoon is slowly moved, until 8mg toward spoon is outer.After having taken, if also have methyltestosterone in spoon, residual methyltestosterone is put into and specified in returnable, finally spoon paper using is wiped clean, rotate turning handle and make propeller get back to original position.

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