Chinese patent Granted publication number: CN202092923U, Dec 28 2011 Granted publication day, a kind of water absorption tester is disclosed, comprise base, its special character is: be provided with riser on the base, the top level of described riser is provided with the kapillary with scale, one side of described riser is provided with sintered filter funnel, the outlet of described sintered filter funnel links to each other with a described end capillaceous by flexible pipe, and core filtering layer upper surface and the described kapillary of described sintered filter funnel are in the same level position.Its weak point is, this utility model is only applicable to have the water-intake rate of the particle of water absorptivity and capillary effect and measures, and the water absorptivity that is not suitable for the plastics model with writing board shape is measured.
The utility model content
The utility model is that the water-intake rate that is only applicable to have the particle of water absorptivity and capillary effect in order to overcome prior art is measured, be not suitable for the deficiency of the water absorptivity mensuration of the plastics model with writing board shape, provide a kind of simple in structure, easy to use, can carry out the plastic-like board fixer that water absorptivity is measured to the different types of plastics model with writing board shape simultaneously.
To achieve these goals, the utility model is by the following technical solutions:
Plastic-like board fixer in a kind of water absorptivity determination test of the present utility model, the plastic-like board fixer of described plastic ink absorption mensuration comprises train wheel bridge and lower plate, described lower plate bottom surface is fixedly connected with supporting leg, the lower plate end face is provided with the guide rod that is fixedly connected with it, described train wheel bridge is positioned at the lower plate top and is slidingly connected with guide rod, and is folded with the plastics model between train wheel bridge and the lower plate.The utility model fixes the plastics model by train wheel bridge and cooperating of lower plate, the plastics model can be immersed in the water and with water fully fully to be contacted, guarantee that simultaneously the plastics model can not shake and topples over, improve stability, in addition, train wheel bridge and guide rod are slidingly connected, can adjust spacing between train wheel bridge and the lower plate along the guide rod train wheel bridge that slides, to adapt to the height of different plastics models, in addition, supporting leg can avoid between the plastics model with train wheel bridge, lower plate or plastics model and container between have face to contact, in order to avoid affect the accuracy of test findings.
As preferably, described train wheel bridge and lower plate are rectangle, and all have the grid that is strip and matches on train wheel bridge and the lower plate, and wherein one group of diagonal angle of described plastics model is embedded in respectively in the grid on train wheel bridge and the lower plate.The diagonal angle of plastics model be embedded in respectively train wheel bridge and lower plate on be strip and the grid that matches in, can place a plurality of plastics models between train wheel bridge and the lower plate, simultaneously different types of plastics model being carried out water absorptivity measures, and grid also plays spacing effect, the plastics model fixedly is shelved between train wheel bridge and the lower plate can not rocked, grid can also guarantee that the distance between each plastics model equates in addition, to improve the precision of water absorption test, avoid between the plastics model or plastics model and container between have face to contact, in order to avoid affect the accuracy of test findings.
As preferably, described supporting leg is vertically fixed on the corner location place of lower plate bottom surface, wherein the supporting leg at least one group of diagonal position place extends upward the formation guide rod, position corresponding with guide rod on the bottom surface of described train wheel bridge is fixed with sliding sleeve, described guide rod passes sliding sleeve and train wheel bridge from the bottom up successively, and described sliding sleeve is fixed by the tight fixed bolt and the guide rod that are positioned at its side.Supporting leg is located at the corner location place of lower plate bottom surface, and it is more stable that whole device is placed; Guide rod passes sliding sleeve and train wheel bridge from the bottom up successively, sliding sleeve is fixed by the tight fixed bolt and the guide rod that are positioned at its side, only need by the i.e. slidably or fixing sliding sleeve of degree of tightness tight fixed bolt, thereby adjust distance between train wheel bridge and the lower plate to adapt to the plastics model of differing heights, easy to adjust.
As preferably, described train wheel bridge, lower plate, supporting leg, guide rod, sliding sleeve, tight fixed bolt are stainless steel.Stainless steel is heavier, and density is greater than water, can avoid plastics exemplar that density is lower than water at the trial because stirring or the nonsteady behaviors such as come-up occur in the water boiling, and can not get rusty long service life.
Therefore, the utlity model has following beneficial effect:
(1) can be simultaneously for having writing board shape and being the water absorptivity mensuration of different types of plastics model;
(2) avoid between the plastics model or plastics model and container between have face to contact, can improve the precision of water absorption test;
(3) can adapt to the plastics model of differing heights;
(4) simple in structure firm, easy to use.
