Abstract
The utility model relates to a double-supporting point position exchanging device which comprises a suspension rod supporting frame and two suspension rods, wherein the suspension rod supporting frame is composed of two supporting arms and a connection board which integrates the supporting arms, the two supporting arms are both provided with positioning slots, and the suspension rods are provided with positioning components which are matched with the positioning slots. Because the double-supporting point position exchanging device of the utility model is additionally provided with the supporting arms, the problem that the suspension rod can generate lateral swinging with the translation of the suspension rod supporting frame and a cantilever is solved, and the butting accuracy of a hook and a measurement ring on the upper part of the suspension rod supporting frame is ensured. The utility model has the advantages of reliable and convenient operation and little repetitive error, and therefore, the operation time is efficiently saved, and the work efficiency is increased.
Description
Technical field
The utility model relates to a kind of experimental provision, and handover measurement hangs two fulcrum transposers of sheet when being specially adapted to the mould measurement of surface tension of liquid or gas-liquid interface unimolecular layer surface.
Technical background
Hang the sheet method and measure in the process of surface tension of liquid or gas-liquid interface unimolecular layer surface mould using into honest and clean rice (Wilhelmy), between measuring one-shot measurement and next time, hanging sheet must strictly clean or change, be operating as manual replacing in the past, lose time, also increased the loaded down with trivial details property of measuring, and introduce measuring error easily, on this question, the applicant has applied for and has obtained the utility model patent that name is called " transposer ", the patent No. is ZL01204638.8, its structure comprises suspension rod, boom support, cantilever, movable sleeve, control crank, stationary shaft and gear plate, wherein, an end and the boom support of cantilever are fixed together, and the other end is provided with vertical through hole and sidewall connecting hole, suspension rod hangs on the two ends of boom support, the upper end of stationary shaft and gear plate are fixed on the frame, and cantilever excessively forms with stationary shaft by movable sleeve and is slidingly matched, and is controlled by the transposition groove control crank that passes the gear plate.Should " transposer " during measuring, need not to interrupt measuring, and only can realize just that by the manual control handle sheet that hangs that more renews proceeds to measure, thereby save Measuring Time, improve work efficiency.But, still the problem of Cun Zaiing is: should " transposer " between boom support and suspension rod, be that single fulcrum contact, suspension rod is with can the generation transverse shakiness in boom support and the cantilever translation, influences docking of boom support upper hooks and measurement ring, when serious even unhook, force experiment to be interrupted.
The utility model content
In order to overcome the above problems, the utility model provides a kind of two fulcrum transposers that prevent that suspension rod from rocking in moving process, has solved the failure problem that docks that the suspension rod transverse shakiness causes suspension hook and measurement ring.
To achieve these goals, the utility model provides a kind of pair of fulcrum transposer, comprises boom support and two suspension rods.Wherein said boom support is formed by two supporting arms with the web joint of this supporting arm one, is equipped with locating slot on described two supporting arms, and described suspension rod is provided with the keeper that matches with described locating slot.
The two fulcrum transposers of the utility model, wherein said two supporting arm along continuous straight runs are arranged in parallel.
The two fulcrum transposers of the utility model, wherein said two supporting arms vertically are arranged in parallel.
The two fulcrum transposers of the utility model, wherein said locating slot is four, they are distributed on described two supporting arms in twos opposed to each other.
The two fulcrum transposers of the utility model, wherein said locating slot is " V " shape; Keeper is " Λ " shape cross bar on the described suspension rod.
The advantage of the two fulcrum transposers of the utility model is, its boom support is by two supporting arms and the couple structure formed with the web joint of this supporting arm one, increased a supporting arm, so the two fulcrum transposers of the utility model have solved suspension rod with the problem of rocking in boom support and the cantilever translation, thereby guaranteed the accuracy that the suspension rod upper hooks is docked with measurement ring, convenient and reliable operation, butt joint success ratio height, and save the running time effectively, improved work efficiency.
Below, in conjunction with the accompanying drawings the two fulcrum transposers of the utility model are described in further detail.
Description of drawings
Fig. 1 is the decomposition texture synoptic diagram of of the present utility model pair of fulcrum transposer.
Embodiment
As shown in Figure 1, the two fulcrum transposers of the utility model comprise cantilever 1, support 2, two suspension rods 4, gear plate 6, stationary shaft 7 and movable sleeves 8.Wherein boom support 2 is that two supporting arm 2b along continuous straight runs are arranged in parallel, and vertical with cantilever 1 by two supporting arms and the couple structure formed with the web joint of this supporting arm one.Each supporting arm is provided with " V " shape locating slot 2a near the end, and locating slot 2a is opposed in twos distribution.Suspension rod 4 is provided with " Λ " shape cross bar 4c that matches with locating slot 2a.
" V " shape locating slot 2a on the supporting arm 2b cooperates with " Λ " shape cross bar 4c on the suspension rod 4.Locating slot 2a also can be other shapes, as " γ " shape etc.Because the utility model boom support is to the two point supporting of suspension rod, so suspension rod 4 is more stable in the translation process of transposition, thereby has improved merging precision and work efficiency.
The two fulcrum transposers of the utility model hang the identical of sheet transposition and original single fulcrum in measurement, be summarized as follows: when sheet is hung in the needs replacing, control crank 9 in transposition groove 6a, do motion vertically upward drive cantilever 1, boom support 2, suspension rod 4 and on the sheet (not shown) of hanging rise, the result hangs sheet and breaks away from liquid level, and one of them suspension rod 4 breaks away from the suspension ring 5 of sensor simultaneously; Then, control crank 9 is moved horizontally in transposition groove 6a,, hang the sheet (not shown) and remove, make previous suspension rod 4 simultaneously and hang sheet to enter the measuring position from the measuring position thereby drive a suspension rod 4 and one so that cantilever 1 rotates around stationary shaft 7; Control crank 9 is moved downward, so that new suspension rod 4 and hang the liquid level that sheet is reduced to sample is measured next time in transposition groove 6a.
Above content only is a most preferred embodiment of the present utility model.What should emphasize is that under the prerequisite that does not break away from inventive concept, those of ordinary skills should fall within the scope of protection of the present invention various modification and the improvement that the present invention makes.
