Description
Technical field
The utility model belongs to technical field of experiment equipment, particularly a kind of balance on goods and services.
Background technology
Counter balance is the gauging instrument that laboratory is commonly used, and balance on goods and services common in prior art is 2 roundels.Because test tube, centrifuge tube etc. cannot be fixed on balance on goods and services, the test tube of reagent chemicals, centrifuge tube etc. are housed and can not be placed directly on balance on goods and services and weigh.
On July 18th, 2007 application number be 200520125376.1 innovation and creation disclose a kind of slip-spring top-loading balance weighing cup, be made up of cylindrical tube, fixed mount, spring, the cylindrical shell of slip-spring top-loading balance weighing cup is cylindric, with bayonet socket on fixed mount, and the bottom center at the bottom of spring is fixed on tin.This programme operation is more loaded down with trivial details, and can not make adjustment according to the size of test tube caliber.On August 13rd, 2014, application number was that the innovation and creation of 201420076523.X disclose a kind of balance on goods and services for centrifuge tube, it is provided with one piece of permanent magnet in the center, lower surface of counter balance main body, the center line of permanent magnet and the center line of counter balance main body coincide, and counter balance body upper surface is axially at least processed with the centrifugal pore of 2 different pore sizes, different depth.Because this utility model is at the axial centrifugal pore being processed with at least 2 different pore sizes, different depth of right cylinder balance on goods and services body upper surface, the aperture of centrifugal pore is identical with the external diameter of centrifuge tube, when carrying out trim to centrifuge tube, the bottom of this utility model is placed on balance weighing apparatus pallet, the magnet adsorption of bottom face is on the retort stand of balance on goods and services, play the effect of stabilizing tray, by needing the centrifuge tube of trim to be arranged in centrifugal pore of the present utility model, achieve hydro-extractor trim.The weak point of the program is: can not ensure that the center of gravity of centrifuge tube is positioned on the perpendicular line of balance on goods and services central point, greatly can increase the error of weighing.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of balance on goods and services, and it is applicable to the test tube of fixing different-diameter, and ensures that the center of gravity of test tube is on the vertical line at place, center of pallet all the time.
To achieve these goals, the technical solution of the utility model is as follows: a kind of balance on goods and services, comprise tray body, described tray body is provided with at least 2 support chips, the top of support chip is hinged on the edge of tray body, and the bottom of support chip is positioned at the bottom of tray body upper bottom surface, the bottom of support chip is curved, the bottom of each support chip surrounds a circular space, and circular space is positioned at directly over support chip bottom centre, by elastic webbing lateral connection between each support chip.
During use, circular space is stretched into by finger finger belly, the support chip of balance on goods and services is dug, softened the obtaining enough greatly of circular space surrounded when the bottom of each support chip puts into test tube, and test tube fastening makes test tube vertical in tray body as the crow flies by the bottom of support chip under the effect of elastic webbing.The balance on goods and services putting counterweight is identical with the balance on goods and services putting test tube, the circular space that bottom counterweight being inserted each support chip surrounds, when counterweight is more, can stacked after utilize the elasticity of elastic webbing counterweight to be pressed in the center of balance on goods and services, thus decrease weighing error.
As improvement, the shape of described support chip is corresponding to the shape of tray body inwall.
The shape of support chip and the shape of tray body inwall, refer to that support chip can be fitted the inwall of tray body.
As improvement, the quantity of described support chip is 4 ~ 6, and 4 ~ 6 support chips can support test tube reposefully, and the quantity of support chip is crossed test tube at least and easily tilted.
As improvement, described elastic webbing is fixed on the adjacent side of each support chip, and this is a kind of set-up mode of elastic webbing.
As further improvement, described elastic webbing is annular, and elastic webbing is fixed on the bottom surface of each support chip, and this is the set-up mode of another kind of elastic webbing.Which can padded slightly circular space, and convenient finger finger belly has dug support chip.In addition, this kind of mode elastic webbing is easier to fix.
As further improvement, there is extension at the edge of described tray body, to block that to realize support chip spacing when support chip turns up to the portion of being extended during extreme position.
This programme is equivalent to the article containing space increasing tray body, when the object volume weighed is larger, support chip can be turned up to extreme position.
As further improving, the upper bottom surface of described support chip has a cylinder, and cylinder is near the top of support chip.
When weighing medicine, pan paper lighter weight, is easily blown off.After adopting this programme, by the edge of pan paper through cylinder, the fixing of weighing paper can be realized.
As further improving, the extension of described tray body is provided with through hole, the upper bottom surface of described support chip has a cylinder, and when the support chip portion of being extended is blocked, cylinder is positioned at through hole.
Due to the existence of elastic webbing, when support chip turns up to extreme position, external force one is touched, and support chip has restorable trend, although support chip is toward reclaiming the effect playing fixing large volume object.If but user does not want to allow support chip back, then can adopt this programme.Once after cylinder is inserted through hole, even if the External Force Acting that support chip is subject to a certain size also can not be out of shape.
As further improving, described tray body has a depression, depression is positioned at the center of tray body upper bottom surface.
Cave in the circular space that the bottom of each support chip can be assisted to surround, and ensures that test tube can stand in the center of tray body vertically.
In sum, the utility model has that structure is simple, practical function, advantage easy to use, and successful, can be fixed on balance on goods and services rapidly, vertically by test tube, centrifuge tube etc., also help the weighing accuracy improving counter balance simultaneously.
