According to the device, a large lens barrel is divided into two parts through a positioning ring, and one part is provided with a laser cylinder with a laser, a lens cylinder with a lens and a rolling stopping ring. The adjusting hand wheel is rotated to squeeze a spring in a ballhead plunger to adjust the distance between the laser cylinder and the lens cylinder to achieve light source collimation. The other part is provided with two cylindrical lens cylinders, collimating light forms required laser beams through two cylindrical lenses. The laser beam adjusting device through the hand wheel is compact in structure, and simple to debug, and is mainly applied to optical systems of blood analyzers.
Description
Technical field
The present invention relates to the optical check that a kind of flow cytometer or particle analyzer are particularly related to a kind of hematology analyzer for the analyzing blood product sample.The present invention is a kind of light source regulating device, is used for the formation of light beam.
Background technology
As the haemocyte that detects in the blood, use the method for flow cytometer well known.This flow cytometer is by the flow through particle of flow chamber of illumination, detects optical information that particle sends and carries out particle analysis.
Form required laser beam, the light source process multiaspect mirror that needs laser instrument to send carries out certain collimation, filtering etc. to light.And the distance between laser instrument and mirror, mirror and the mirror there is accurate requirement.Therefore form required light beam and need special regulating device.
In recent years, the miniaturization of the analytical equipment that is equipped with flow cytometer such as blood analyser etc. is required to increase day by day, but existing light source controlling mechanism laser instrument and the distance between lens mainly relies on threaded adjusting, one-piece construction is complicated, and volume is also bigger.
Summary of the invention
Technical matters to be solved by this invention is, overcomes the deficiencies in the prior art, and a kind of light source regulating device simple and compact for structure is provided.
The technical solution adopted for the present invention to solve the technical problems is: the device that a kind of armrest wheel is regulated, mainly comprise big lens barrel, be used for installing cylindrical mirror the cylindrical mirror cylinder, be used for installing collimation lens the circle lens cylinder, be used for installing the laser instrument cylinder of laser instrument, big lens barrel is divided into before and after two-part set collar, spline ring, the control hand wheel of regulating laser alignment, bulb plunger, the end cap that spring is contained in inside.
Described big lens barrel one end has screw thread, meshes with control hand wheel.Control hand wheel is regulated the distance of tube inner laser device cylinder and lens cylinder, makes laser alignment.In the big lens barrel gathering sill is arranged, an effect is the installation direction of determining the cylindrical mirror cylinder.There is the pin of protrusion to slide along groove on the cylindrical mirror cylinder.Another effect is that the spline ring is installed, and on the spline ring boss is arranged, and turns control hand wheel the spline ring is moved along groove, promotes the laser instrument cylinder and advances or retreat, and prevents from that the laser instrument cylinder from changeing to rotate with handwheel.
Described bulb plunger is installed in the circle lens cylinder, and three evenly distribute, play the effect of readjustment laser positions.The laser instrument cylinder is near the lens cylinder when tightening control hand wheel, and the spring in the bulb plunger in the middle of laser instrument cylinder and lens cylinder is compressed; When returning stubborn control hand wheel, under the effect of spring force, the laser instrument cylinder is away from the lens cylinder.So just, can regulate laser instrument cylinder and lens cylinder distance, regulate laser alignment.
Have groove on the described set collar, screw is stuck in the interior fixedly set collar of groove after being screwed into big lens barrel, and set collar and control hand wheel define laser instrument cylinder and lens cylinder space.And need not cylindrical mirror when regulating collimation, after the position of set collar made and regulates collimation, the big lens barrel other end had two cylindrical mirror cylinders of enough space mounting.
The invention has the beneficial effects as follows that utilize bulb plunger and threaded engagement to regulate collimation, and make laser instrument and three mirror contact lens in a cylinder, volume simple and compact for structure is little; The employing handwheel is regulated, handled easily.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.

Fig. 2 A is the cut-open view of bowing of big lens barrel when regulating laser alignment.
Fig. 2 B is the main cut-open view of big lens barrel when regulating laser alignment
Fig. 3 is the main cut-open view of big lens barrel behind the installation cylindrical mirror.
1. big lens barrel, 2. control hand wheel, 3. spline ring, 4. set nut one, 5.O the type circle, 6. little pin, 7. sleeve, 8. laser instrument, 9. laser instrument cylinder, 10. bulb plunger, 11. lens cylinders, 12. lens, 13. trim rings, 14. set nuts two, 15. locating ring, 16. holding screws, 17. cylindrical mirrors, 18. pin, 19. cylindrical mirror cylinders, 20. end caps
Embodiment
In the big lens barrel 6 inner body exploded views of Fig. 1, set nut 1, O type circle 5, little pin 6, sleeve 7, laser instrument 8 and 9 combinations of laser instrument cylinder are fixed on laser instrument 8 in the laser instrument cylinder 9.Lens cylinder 11, lens 12, trim ring 13 and set nut 2 14 combinations are fixed on lens 11 in the lens cylinder 10.Cylindrical mirror 17 is fixed in the cylindrical mirror cylinder 19 by four angle point glue.
Locating ring 15 passes in the groove that threaded hole on the big lens barrel 6 is stuck in locating ring 15 assigned address that locating ring 15 is fixed in the big lens barrel 1 by holding screw 16.
Big lens barrel 1 one ends have screw thread, and control hand wheel 2 can be screwed on the big lens barrel 1 by screw thread.
Uniform three blind holes on the lens cylinder 11, three bulb plungers 10 can be filled in and be fixed in the blind hole on the lens cylinder 11.
The groove fit that one boss and big lens barrel 1 are arranged on the spline ring 3 can only and can not be rotated the spline ring along the groove slip.
Pin 18 is squeezed into cylindrical mirror cylinder 19, and the groove that pin is aimed in the big lens barrel in the time of in being installed to big lens barrel 1 plays the effect of locating the cylindrical mirror direction.
Below, describe embodiments of the present invention in detail with reference to accompanying drawing 2A, Fig. 2 B and Fig. 3.
After holding screw 16 is screwed into big lens barrel 1, snap in the groove of locating ring 23 assigned address that set collar is fixed in the big lens barrel 1, big lens barrel is divided into former and later two parts.Control hand wheel 3 and locating ring define the activity space of laser instrument cylinder and lens cylinder.
Make laser instrument cylinder 16 squeeze bulb plungers 17 by tightening control hand wheel 3 promotion spline rings 10, the spring in the bulb plunger 17 is compressed, and laser instrument 15 is near lens 19.Return stubborn control hand wheel 3, under the effect of spring force, bulb plunger 17 promotes laser instrument cylinder 16 away from lens cylinder 18.When two cylinders were adjusted to correct position, laser beam scioptics 19 reached collimation.Four through holes are arranged on the control hand wheel 3, inject glue in the hole after, can secured adjusted handwheel 3, the distance of laser instrument 15 and lens 19 is remained unchanged, finish the adjusting of laser beam collimation.
As Fig. 3, after having regulated laser alignment, two cylindrical mirror cylinders 19 can be put into from the opposite side of big lens barrel 1 by assigned direction.By being fixed on, end cap 20 fixes two cylindrical mirror cylinders on the big lens barrel 1.
