Specific embodiment
Illustrate embodiments of the present invention below by way of specific specific example, those skilled in the art can be by this specificationOther advantages and efficacy of the present invention can be easily understood for disclosed content.The present invention can also pass through in addition different specific realitiesThe mode of applying is embodied or practiced, the various details in this specification can also based on different viewpoints and application, without departing fromVarious modifications or alterations are carried out under spirit of the invention.
It should be noted that cited such as "upper", "lower", "left", "right", " centre " and " one " in this specificationTerm is merely convenient to being illustrated for narration, rather than to limit the scope of the invention, the change of relativeness or tuneIt is whole, under the content of no substantial changes in technology, when being also considered as the enforceable scope of the present invention.
Before the embodiment of the present invention is described in detail, first application environment of the invention is described.The present inventionTechnology mainly be applied to micro-imaging technique field, be especially applied to optical tomography (OCT) and whole audience lightIt learns chromatography imaging technique (FFOCT), for example is used for high magnification microscope, scanning confocal microscope, bis- (more) photon microscopes, lightLearn the sample room of the immersion micro-imagings of imagings such as chromatography microscope.
As depicted in figs. 1 and 2, the sample room for immersion micro-imaging of the embodiment of the present invention, including pedestal 7, tunePedestal 8 and gland 1 are saved, adjustment base 8 and gland 1 are separately mounted to the both ends of pedestal 7, and are formed and opposite with pedestal 7 can be turnedDynamic symmetrical structure.The cylindrical structure in sample room completed is assembled, gland 1 and adjustment base 8 are symmetrical arranged.
As shown in Figures 1 to 10, the top of pedestal 7 is equipped with the boss 72 for carrying sample, is arranged on boss 72 usefulIt is connect by elastic mechanism with pedestal 7 in the bottom of the window assembly for pushing down sample, window assembly, and is driven by elastic mechanismWindow assembly floats up and down adjustment, so that window assembly is able to achieve the fixation to tissue sample.Gland 1 pushes down the top of window assemblyPortion, gland are capable of being mounted on pedestal 7 of lift adjustment, and 1 lift adjustment of gland depresses the height of window assembly, wherein pedestal 7For stepped cylinder structure, pedestal 7 is equipped with external screw thread 73, and the top of gland 1 is equipped with the limiting section 12 extended inwardly, limitPortion 12 pushes down window assembly, and 1 inside cylindrical face of gland is equipped with fine thread 11, and gland 1 and pedestal 7 are threadedly coupled, rotation pressure1 oscilaltion of lid, and elastic mechanism is cooperated just to realize the height adjustment of window assembly.The outside cylindrical surface 13 of gland 1 and baseIt is equipped with and embroiders on the outside cylindrical surface 74 of seat 7, when rotation process, increase the frictional force contacted in operation with finger.The top that gland 1 is located at boss 72 is equipped with observation panel 14, is equipped with transparent panel at observation panel 14, is being convenient for by the way that transparent panel is arrangedThe leakproofness inside sample room is also ensured when observing the sample on boss 72.
As shown in Figures 1 to 10, window assembly includes sleeve 2, and one end of sleeve 2 is equipped with the limiting section extended inwardly21, sleeve 2 is interior to install sheet glass 3 and pressing ring 4, and between limiting section 21 and pressing ring 4, the outer wall of pressing ring 4 is equipped with outer sheet glass 3The inner wall of screw thread, sleeve 2 is equipped with internal screw thread 22, and pressing ring 4 is threadedly coupled with sleeve 2, and when window assembly assembles, rotational sleeve 2 makesIt obtains the movement of pressing ring 4 and cooperates pressed glass piece 3 with limiting section 21, complete the assembly of window assembly.Sheet glass 3 can using commonly atThe window glass of picture, also can be used glass slide, thickness is selected according to microscope.Between sleeve 2 and pressing ring 4Interaction force is little, can be fabricated using aluminum alloy materials, advantageously reduce weight and cost.The outside circle of sleeve 2Cylinder 24 is equipped with and embroiders, and increases the frictional force contacted in operation with finger.Sleeve 2 is equipped with far from one end of limiting section 21First pin hole 23, pedestal 7 are equipped with second pin hole 71 corresponding with the first pin hole 23, and the both ends of elastic mechanism are separately mounted to theIn one pin hole 23 and the second pin hole 71, the aperture of the second pin hole 71 is greater than the aperture of the first pin hole 23.Elastic mechanism includes pin 5With spring 6, the diameter of pin 5 is less than the internal diameter of spring 6, and the upper end of pin 5 is mounted in the first pin hole 23, and with the first pin hole23 are fitted close；The lower end of pin 5 is mounted in the second pin hole 71, and the lower end of spring 6 is mounted in the second pin hole 71, and withTwo pin holes, 71 inner wall is fitted close, and spring 6 is set on pin 5, and the second pin hole 71 is stretched out in the upper end of spring 6, withstands sleeve 2,It floats upwards for sleeve 2 and elastic force is provided, when 1 push-window component of gland, spring 6 generates damping to window assembly.FirstThe quantity of pin hole 23 is at least one, and the first pin hole 23 is identical with the quantity of the second pin hole 71, in the present embodiment, the first pinThe quantity of hole 23 and the second pin hole 71 is three, can not only by the cooperation of the first pin hole 23, the second pin hole 71 and elastic mechanismIt is enough that the fixed sample of adjustment that floats is carried out to the position of window assembly, moreover it is possible to limit the rotary freedom of sleeve.
As shown in Figures 1 to 10, adjustment base 8 includes knob 81 and the threaded rod 82 being arranged on knob 81, pedestal 7Bottom is equipped with the threaded hole 75 cooperated with threaded rod 82, and turning knob 81 makes 7 lift adjustment height of pedestal, to realize sampleThe height adjustment of room.In use, adjustment base 8 can be used cooperatively with Two-dimensional Position moving stage, facilitate sample room mobile.
Sample room of the invention has the advantage that
1) sample fix stably.Interaction between the elastic force of the pressure and spring that are generated by gland, it is accurate to controlThe position of sheet glass and the stress of sample, so as to guarantee the stabilization of sample；The rotation of window assembly is limited using pinFreedom degree ensure that sample in fixation procedure, i.e., during the pushing of gland, with sheet glass contact position phase does not occur for sampleTo displacement.
2) compact-sized, it is easy to carry.The sample room includes that sample is fixed and whole height adjusts two functions simultaneously, noIt needing additionally to increase height adjustment mechanism, is threadedly engaged by itself and height adjustment can be realized, small volume is easy to carry,Also ensure sample room inner sealing performance.
3) structure is simple, high reliablity.The sample room is compared with conventional sample chamber, reduces the quantity of part, no fasteningThe fasteners such as screw or bolt；Sample room height is adjusted using Mechanical Method, reduces the variable of adjustment process.
The above-described embodiments merely illustrate the principles and effects of the present invention, and is not intended to limit the present invention.It is any ripeThe personage for knowing this technology all without departing from the spirit and scope of the present invention, carries out modifications and changes to above-described embodiment.CauseThis, institute is complete without departing from the spirit and technical ideas disclosed in the present invention by those of ordinary skill in the art such asAt all equivalent modifications or change, should be covered by the claims of the present invention.
