Abstract
The utility model discloses a filter-fixing component, which comprises a filter wheel, filters, shims and fastening pieces corresponding to the shims, wherein, the filter wheel is provided with a mounting end surface, which is provided with axial mounting holes, the filters are mounted into the corresponding mounting holes, the edge of each filter is pressed by at least one shim, each shim presses the edges of one or two shims, and the fastening pieces are fixed on the filter wheel and press corresponding shims. Because the filter-fixing component applies one shim to press the edges of one or two shims and uses the fastening pieces to fix the filters, not only is fixing simple and reliable, but also a filter can be conveniently disassembled and replaced only by loosening the fastening piece fixing the filter. Moreover, the gap between the filter and the mounting hole can be small, so the mounting precision of the filters is high.
Description
Technical field
The utility model is the optical filter fixation kit that is applied in the light path system about a kind of, especially about the optical filter fixation kit in the beam splitting type light path system before a kind of being applied to.
Background technology
The light path system of automatic clinical chemistry analyzer mainly contains two kinds: preceding beam split mode and back beam split mode.Back beam split mode mainly contains two kinds of the beam split of static optical fiber optical filter and concave grating light splitting technologies, though the simple cost of these two kinds of technical patterns is higher.The beam split mode is the light source direct irradiation before adopting, enter receptacle behind the optical filter wheel of light by the cycle rotation, so form hyperchannel beam split colorimetric measurement, optical filter and optical filter wheel rotate the switching of finishing between the different wave length optical filter together, and promptly optical filter is rotating.
The light path system of beam split mode generally adopts the multi-channel filter wheel construction before existing the employing, its primary structure is circumferentially several mounting holes on an optical filter wheel, each mounting hole is equipped with an optical filter and spring or shell fragment, all optical filters are pushed down with a block pressur plate again in the outside, rely on the elastic force of spring or shell fragment to compress optical filter.But this kind multi-channel filter wheel construction has following shortcoming: 1) complex structure, cost height; 2) adopt elastic compression, the gap of optical filter and mounting hole is big, and bearing accuracy is poor; When 3) changing one of them optical filter, when taking pressing plate apart, all optical filters all can drop out, and single optical filter is safeguarded inconvenient.
Summary of the invention
Technical matters to be solved by this invention is, overcomes the deficiencies in the prior art, provide a kind of fixing simple and reliable, bearing accuracy is high and the optical filter fixation kit being convenient to the optical filter dismounting and changing.
The technical solution adopted for the present invention to solve the technical problems is: this optical filter fixation kit comprises optical filter wheel, optical filter, pad and the securing member corresponding with pad, this optical filter wheel has the installation end face, this installation end face is provided with axial mounting hole, optical filter is packed in the corresponding mounting hole, a pad is being pressed at the edge of each optical filter at least, each pad is being pressed the edge of one or two optical filter, and this securing member is fixed on this optical filter wheel and is pressing corresponding pad.
Two pads are being pressed at the edge of described optical filter at least.
The described pad of same optical filter of pressing is symmetrically distributed.
The installation end face of described optical filter wheel is provided with and securing member threaded hole one to one, and securing member passes corresponding pad and screws with corresponding threaded hole.
The same circle distribution of described mounting hole and threaded hole, and the both sides of each mounting hole are equipped with threaded hole.
Described same pad is being pressed the edge of two adjacent optical filters.
Described mounting hole and threaded hole distribute with circumference.
Described optical filter thickness in the axial direction is less than the corresponding mounting hole degree of depth in the axial direction.
The invention has the beneficial effects as follows, this optical filter fixation kit adopts a pad to push down the edge of one or two optical filter, and optical filter is fixed with securing member, not only fix simple and reliable, and when changing optical filter, as long as unclamp the securing member of fixing this optical filter, just can be for convenience detach and change optical filter; In addition, the gap of optical filter and mounting hole can be less, the bearing accuracy height of optical filter.

Fig. 4 is the left view of the second embodiment optical filter fixation kit.
Embodiment
As shown in Figures 1 and 2, present embodiment optical filter fixation kit comprises optical filter wheel 1, optical filter 2, pad 3 and securing member 4.This optical filter wheel 1 has the end face 11 of installation, and this installation end face 11 is provided with a plurality of axial mounting hole 12 and a plurality of threaded hole with circle distribution, and the symmetria bilateralis of each mounting hole 12 is provided with two threaded holes.This optical filter 2 has a plurality of and is corresponding one by one with mounting hole 12, and in the axial direction, the thickness of optical filter 2 is slightly larger than the degree of depth of corresponding mounting hole 12, and optical filter 2 is packed into behind the corresponding mounting hole 12, and optical filter 2 can expose this installation end face 11 about 0.4mm.This pad 3, securing member 4 and threaded hole are corresponding one by one.The edge of each optical filter 2 is pushed down by two pads 3, and each securing member 4 passes corresponding pad 3 back and corresponding threaded holes and screws, and each securing member 4 all presses corresponding pad 3, and optical filter 2 is fixed on the optical filter wheel 1.
As shown in Figures 3 and 4, this mounting hole and this threaded hole can distribute with circumference, make each pad 3 all between two adjacent optical filters 2, make same pad 3 can press the edge of two adjacent optical filters 2.
This optical filter fixation kit adopts a pad to push down the edge of one or two optical filter, and same optical filter is pressed by two pads, and with securing member optical filter is fixed.When changing optical filter, as long as unclamp two securing members (as screw) of fixing this optical filter, just can easy disassembly, because each optical filter fixedly is independently, when changing single optical filter other optical filter is not influenced.For this optical filter fixation kit, the gap of optical filter and mounting hole can be less, the precision height that optical filter repeats to install; Single optical filter can be dismantled separately and change, and whole fixed sturcture is simple and reliable.
This fixed sturcture not only can be used for the light path system of automatic clinical chemistry analyzer, also can be used on the light path system of equipment such as microplate reader or coaglation analyzer.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
