The utility model discloses a kind of optical spectrometer sample clamping device, belongs to clamping device field.The optical spectrometer sample clamping device includes spark table; the spark table lower end is provided with protective cover; the spark table and the protective cover are provided with through-hole; the spark table is overlapped with the through-bore axis of the protective cover and perpendicular to the working face of spark table; sliding axle passes through through-hole; sliding axle is made in through-hole around axial rotation, so that compressing point can be adjusted in the larger context.Compressed spring is cased on sliding axle, and the compressed spring bottom is fixed on the sliding axle, the compressed spring diameter is greater than through-hole diameter, and the sliding axle upper end is fixedly connected with cross bar, pressure-like needle is connected on the cross bar.At work, elastic force downward by compressed spring always, sample upper surface is by a clamping force vertically downward, and always perpendicular to spark table for sliding axle.In addition the clamping device when not in use, can be close to spark table placement, not influence the space on spark table.
Description
Technical field
The utility model relates to a kind of clamping device field, in particular to a kind of optical spectrometer sample clamping device.
Background technique
General sample clamping device be the formula that is rotated up and down or need a root post and be fixed on spark table, utilize
Moving up and down for cross bar is compressed to be compressed.The direction of this method power when compressing is not necessarily vertical with platen, it is easy so that
Sample is moved in analysis, influences data analysis.
Utility model content
The purpose of this utility model is to provide a kind of optical spectrometer sample clamping device, when solving to compress the direction of power with
Table top out of plumb influences the problem that data are analyzed and cross bar occupied space is big so that sample is moved in analysis.
In order to solve the above technical problems, the utility model provides a kind of optical spectrometer sample clamping device, which includes
Cremator, the spark table lower end are provided with protective cover, and the spark table and the protective cover are provided with through-hole, the spark table
It is overlapped with the axis of the protective cover and perpendicular to the working face of spark table, sliding axle passes through through-hole, is cased on the sliding axle
Compressed spring, and the compressed spring bottom is fixed on the sliding axle, the diameter of compressed spring is greater than through-hole diameter, described
Sliding axle upper end is fixedly connected with cross bar, and pressure-like needle is connected on the cross bar.
Further, insulation pinboard is additionally provided between spark table and protective cover, the insulation pinboard is provided with through-hole.
Further, it is provided with sliding bearing in protective cover, the sliding bearing inner ring and sliding axle clearance fit.
Further, the sliding axle bottom is additionally provided with circlip, and the compressed spring bottom passes through circlip and sliding axle
Bottom is fixedly connected.
Further, the pressure-like needle is connect by adjusting screw with cross bar, can unclamp the adjusting screw to described
Pressure-like needle is adjusted.
In optical spectrometer sample clamping device provided by the utility model, the pressure-like needle is formed with cross bar, sliding axle
Moving parts can only be moved up and down under the constraint of sliding bearing and around axial rotation, therefore pressing force is vertical always
In spark table, and since cross bar axially rotates, the compression range of clamping device is fan-shaped anchor ring, can be adapted to sample shape size
Biggish difference.In addition this clamping device when not in use, can be close to spark table placement, the sky being not take up on too many spark table
Between.
Detailed description of the invention
Fig. 1 is optical spectrometer sample clamping device cross-sectional view.
Specific embodiment
Below in conjunction with the drawings and specific embodiments to the utility model proposes a kind of optical spectrometer sample clamping device make into
One step is described in detail.According to following explanation and claims, will be become apparent from feature the advantages of the utility model.It should be noted
It is that attached drawing is all made of very simplified form and using non-accurate ratio, only to facilitate, lucidly aid in illustrating this reality
With the purpose of new embodiment.
The main purpose of the utility model is to provide a kind of optical spectrometer sample clamping devices.
In order to realize the purpose, which includes spark table 5, and 5 lower end of spark table is disposed with insulation switching
Plate 4 and protective cover 3, the spark table 5, insulation pinboard 4 and protective cover 3 are provided with through-hole, the spark table 5 and insulation pinboard
4, the through-bore axis of protective cover 3 is overlapped and perpendicular to the working face of spark table 5, and the insulation pinboard 4 is for preventing electrostatic pair
Dissection has an impact；Sliding axle 6 passes through through-hole.Be provided with sliding bearing 11 in the protective cover 3, the sliding axle 6 with it is described
11 inner ring clearance fit of sliding bearing.6 upper end of sliding axle is fixed with cross bar 7, and the cross bar 7 is connected by adjusting screw 8
There is pressure-like needle 9, the position of pressure-like needle 9 can be adjusted after unclamping adjusting screw 8.Pact of the sliding axle 6 in sliding bearing 11
Under beam, make around axial rotation, so that compressing point can be adjusted in the larger context, sample shape size can be adapted to
Bigger difference.
Compressed spring 2 is cased on the sliding axle 6,2 bottom end of compressed spring is solid by circlip 1 and 6 bottom of sliding axle
Fixed connection, when the device is in off position, it is long that 2 length of compressed spring is equal to its original.Sliding axle 6 is in compressed spring 2
Under effect, when so that sliding axle 6 working, elastic force downward by compressed spring 2 always, according to the transmitting of power, the meeting pair of pressure-like needle 9
10 upper surface of sample generates a clamping force vertically downward, and always perpendicular to spark table 5, due to not having in the horizontal direction
Pressure generates, and in analysis, sample will not be moved, and will not analyze data and have an impact.In addition the clamping device does not make
Used time can be close to the placement of spark table 5, not influence the space on spark table 5.
Foregoing description is only the description to the utility model preferred embodiment, not to any limit of the scope of the utility model
Fixed, any change, the modification that the those of ordinary skill in the utility model field does according to the disclosure above content belong to right and want
Seek the protection scope of book.
