The support of the molten model machine of a kind of fluorescence analysis
Technical field
The utility model belongs to measuring technology and sample making apparatus field, mainly proposes the support of the molten model machine of a kind of fluorescence analysis.
Background technology
Molten model machine is used to found the glass sheet that the χ ray fluorescence analysis is used, and support is mainly used in support, fixedly the crucible of sample is housed.Support can rotate, and can tilt forward and back with molten model machine body of heater to wave, and makes the molten sample fusing of institute evenly.In rotation, swing process, crucible can be fixed, and unlikely coming off causes spilling sample.Molten model machine support is generally made by heat-resisting steel.Existing supporting structure in use for some time because material oxidation attenuates, crucible when swing, slippage from fixed pin; Or the loosening degree of tilt of support is big, all causes spilling the sample phenomenon.
Summary of the invention
The purpose of this utility model is the support that proposes the molten model machine of a kind of fluorescence analysis, to solve the molten existing deficiency of model machine of existing fluorescence analysis.
The technical scheme that its invention task of finishing the utility model is adopted is:
The support of the molten model machine of a kind of fluorescence analysis, described support comprise body frame and pot frame two parts; Described body frame has three "T"-shaped bars along 120 ° of distributions of circumference, and an end of described "T"-shaped bar is connected with rotation axis, and constituting body frame can be with the structure of rotation axis rotation; Two ends at the horizontal straight-bar of "T"-shaped bar have a pot frame locating piece respectively, and the center of described pot frame locating piece has the axis hole that pot frame coupling shaft is inserted, and each pot frame locating piece all has three arc bumps along 120 ° of distributions of circumference; The framed structure of described pot frame for constituting by annular ring frame, vertical connecting link and bottom support; The coupling shaft of described pot frame inserts in the central shaft hole of pot frame register pin, the upper surface of described pot frame have three circumferentially, with the crucible register pin of the groove fit of crucible; The bottom support of described pot frame have three circumferentially, with pot arc groove that the arc bump of frame locating piece cooperates.
The support of the molten model machine of the fluorescence analysis that the utility model proposes, structural design relatively rationally, simply pick and place crucible conveniently during use, be connected between the support, between the frame crucible rationally; Long service life.

Embodiment
The embodiment that provides in conjunction with the accompanying drawings is illustrated the utility model:
The support of the molten model machine of a kind of fluorescence analysis, described support comprises body frame 1 and pot frame 6 two parts; As shown in Figure 1, described body frame 1 has three "T"-shaped bars 3 along 120 ° of distributions of circumference, and an end of described "T"-shaped bar 3 is connected with rotation axis 2, and constituting body frame 1 can be with the structure of rotation axis 2 rotations; Two ends at the horizontal straight-bar of "T"-shaped bar have a pot frame locating piece 4 respectively, and the center of described pot frame locating piece 4 be that each pot frame locating piece 4 all has three arc bumps 12 along 120 ° of distributions of circumference by the axis hole 5 of crucible frame coupling shaft 7 insertions.As shown in Figure 4, the framed structure of described pot frame 6 for constituting by annular ring frame 9, vertical connecting link 10 and bottom support 11; The coupling shaft 7 of described pot frame inserts in the central shaft hole 5 of pot frame locating piece, the upper surface of described pot frame 6 has circumferential three crucible register pins 8, in order to three groove fit of crucible, when placing crucible, crucible is just in time put into register pin 8 along three last grooves, makes crucible safer in the process of rotating and swinging; The bottom support 11 of described pot frame has three circumferential arc grooves 13, cooperates in order to the arc bump 12 with pot frame locating piece 4, can firmly fix the crucible frame, and is not loosening; Make pot frame under the situation that oxidation diminishes, can be stabilized in the pin; On the pot frame 6 of described support, flush the place with crucible register pin 8 bottom level, the bow on two sections support crucible edges is arranged, each section bow is 120 ° of arc length; After the oxidation of pot frame attenuated, crucible when the crucible desire comes off, just in time kept off the edge at crucible from crucible register pin 8 in the process that rotation is waved, make the unlikely inclination of crucible, causes and spills sample; When picking and placeing crucible, crucible tongs can be from the indentation, there gripping freely.
