Description
Technical field
The present invention relates to a kind of spectrophotometric sample holder, particularly a kind of spectrophotometer reads the sample holder that analysing solid sample leads to light quantity/extinction amount, belongs to chemical analysis field.
Background technology
When spectrophotometer uses, sample holder need be adopted to hold sample, and sample holder plays fixed sample, makes light path consistent perpendicular through area, to realize the effect that reading sample leads to light quantity/extinction amount.Because spectrophotometric spot size is little, therefore sample holder is absolutely necessary when using spectrophotometer, and current spectrophotometric application is mostly fluid sample concentration analysis, the sample holder used is a liquid sample pool, the size of sample cell can put into spectrophotometric observation cabin, the fluid sample of q.s to be injected simultaneously, can ensure that light path passes through sample, complete the reading analysis of logical light quantity/extinction amount.Along with the development of S&T tax, spectrophotometer is not limited only to fluid sample analysis, also will analyze the logical light quantity/extinction amount of various solid sample, different from fluid sample, solid sample cannot by the cumulative light path that realizes of sample size just by sample.Therefore relevant enterprise constantly develops various solid sample support, if China Patent No. is 20072007149.7(sample holder), the spectrophotometric solid sample support of 201020293270.3() etc.Though these sample holders can make light path just by sample, structure is also comparatively simple, can not ensure analyze read time sample firm, therefore be difficult to the precision that ensures to analyze.
Summary of the invention
The object of this invention is to provide one can make light path perpendicular through sample, light path is consistent, the solid sample bracket of spectrophotometer that analysis precision is high by the area of sample.
The present invention is achieved in that a kind of solid sample bracket of spectrophotometer, comprise top cover, top board, base plate, also comprise slide block, spring, square groove, through hole A, square hole, threaded hole A, boss, slideway, groove, circular groove, threaded hole B, through hole B, two threaded hole C, through hole C, shallow square groove, bases, wherein said square groove is arranged on described top cover; Described through hole A, square hole, threaded hole A, boss, slideway are all separately positioned on described top board; Described groove, circular groove are separately positioned on described slide block; Described threaded hole B, through hole B, two threaded hole C, through hole C, shallow square groove, bases are separately positioned on described base plate; Described spring is arranged between described slide block and described base plate, described slide block is pressed on to be arranged in the described square groove of described top cover, the groove be arranged on described slide block embeds in slideway that described top board is arranged, described top board and described base plate both are fixedly installed togather by described through hole A, threaded hole A, threaded hole B, through hole C screw, described two threaded hole C are arranged on the base of described base plate, described shallow square groove is the middle part being arranged on described base plate, and described through hole B is the center being arranged on described shallow square groove.
Spectrophotometric solid sample support of the present invention owing to have employed said structure, therefore can make light path perpendicular through sample; Clear field is less than sample in cross section and amasss, the position consistency that sample is fixed at every turn, and light path is consistent by the area of sample, and solid sample is changed fast, and the analysis precision of sample is high.

Embodiment
Below in conjunction with accompanying drawing, for embodiment, the invention will be further described.
First each parts are processed one by one by needed for reality, more each parts successively installation are a spectrophotometric solid sample support.
As shown in Figure 2, open a square groove 6 in the one side of top cover 1, it is of a size of 12mm × 5mm in the present embodiment, is 3mm deeply.Square groove 6 just in time can push down slide block 3, is fixed on slide block 3, for pushing down slide block 3 to change sample.
As shown in Figure 3, the boss 10 be arranged on top board 2 is once compressing with top board 2, is drilled with through hole A7, has slideway 11 in the both sides of boss 10 at the middle part of boss 10, being (as shown in Figure 4) of matching with the groove 12 that slide block 3 has, is the slideway as slide block 3.Also be drilled with a square hole 8 in the lower edge of boss 10, size is 8mm × 10mm, for placing the window taking out and change sample.Also bore a threaded hole A9 in the bottom of top board 2, and match (as shown in Figure 5) with through hole C17, just top board 2 and base plate 4 can be fixedly installed togather by this holes with screw.Slide block 3 is processed into half frame-shaped construction in the present embodiment, groove 12 is cut with respectively in the both sides of half frame, two circular groove 13(are had as shown in Figure 4) at the bottom middle part of underframe, groove 12 matches with two side slideways 11 of the boss 10 on top board 2, such slide block 3 that can make can slide on top board 2, and circular groove 13 is the one end for fixing spring 5.
As shown in Figure 5, base 19 on base plate 4 is once compressing with base plate 4, be drilled with a threaded hole B14 at the central upper portion place of base plate 4, the through hole A7 on this hole and top board 2 matches (as shown in Figure 1), top board 2 and base plate 4 is fixedly installed togather by this holes screw.Have a 6mm × 6mm at the middle part of base plate 4, the shallow square groove 18 of dark 0.5mm, for the position of fixed sample, have a through hole B15 in the center of shallow square groove 18, it passes through for light path, and can ensure that clear field is consistent.Have a through hole C17 and threaded hole A9 in the middle, bottom of base 19 to match, holes is used for fixing top board 2 and base plate 4.Have two threaded hole C16 along its length in the upper of base 19, the surface area of its size and spring 5 matches, and can put into spring 5, spring 5 is inserted rear plug screw and penetrates the other end that this hole can fix spring 5.
As shown in Figure 1, be commercially available by above-mentioned each parts top cover 1, top board 2, slide block 3, base plate 4, spring 5() process one by one by necessary requirement after, slide block 3 is passed on two side slideways 11 of the boss 10 of top board 2, top cover 1 lid is stuck in the groove 12 of slide block 3, after shifting slide block 3 onto the end again, at this moment slide block 3 and top board 2 are combined, then place it on base plate 4, top board 2 and base plate 4 are fixed respectively by through hole A7 and threaded hole B14 and through hole C17 and threaded hole A9 drive screw and are installed together.Be placed on by spring 5 in two threaded hole C16 on the base 19 of base plate 4, block threaded hole C16 with plug screw, in the other end of spring 5 circular groove 13 just bottom slide block 3, this has just assembled to a complete solid sample support.
Fig. 6, Fig. 7 are use schematic diagram of the present invention.
As shown in Figure 6, promote slide block 3 and move down by pressing the lid 1 that bears down on one, holddown spring 5, the lower edge spacing of the boss 10 on slide block 3 underframe and top board 2 increases, replaceable sample.
As shown in Figure 7, unclamp top cover 1, the pressure at this moment on top cover 1 is just eliminated, and spring 5 promotes slide block 3, and the underframe of slide block 3 clamps sample jointly with the lower limb of the boss 10 on top board 2, and ensures that sample is placed firmly.
Because region corresponding with sample on base plate 4 has shallow square groove 18, during replacing sample, this shallow square groove 18 can make sample position be consistent.Meanwhile, region corresponding with sample position on base plate 4 has through hole B15, and the sectional area of through hole B15 is less than sample in cross section and amasss, and light path is consistent by the area of sample, therefore solid sample support of the present invention can reach desired analysis precision.
