Background technology
Many surveying instruments are when work, particularly be applied under cryogenic conditions or the vacuum condition, need trickle and accurate adjusting, to ensure the sensitivity or the spatial resolution of detection system, therefore need a kind of simple to operate, regulate reliable, the regulating device that degree of regulation is higher, but, existing regulating device mostly is the single thread regulating device, and the degree of regulation of single thread regulating device is directly related with pitch, in order to improve degree of regulation, just must reduce pitch, not only Jia Gong difficulty is very big, and the too little physical strength of screw thread that also causes of pitch sharply descends, can't bear big moment, serviceable life is also short.
Summary of the invention
The purpose of this utility model is: solve the processing difficulties of the high single thread regulating device of degree of regulation, and the single thread regulating device short problem in serviceable life that processes, thereby a kind of micrometric displacement regulation device is provided.
The purpose of this utility model is achieved in that a kind of micrometric displacement regulation device of the present utility model, as shown in Figure 1, comprise regulating ring and displacement component, it is characterized in that, also comprise a set collar, described displacement component is the displacement ring, this displacement ring and set collar, the regulating ring coaxial package together, screw thread in the same way is carved with in the inside and outside both sides of regulating ring, the outside screw engagement of screw thread and regulating ring is carved with in the set collar inboard, the inside thread engagement of screw thread and regulating ring is carved with in the displacement ring outside, and the displacement ring also fixes on the set collar by a location lock, guarantees that the displacement ring can only move axially and can't rotate.The difference of the outside screw pitch of the inside thread of displacement ring and set collar is set to required degree of regulation.
Be carved with the displacement index dial on described set collar or the regulating ring.
One rotary handle or rotation handle are set on the described regulating ring.
When using the utility model to carry out the displacement adjusting, at first rotate regulating ring, regulating ring produces axial displacement with respect to set collar, and simultaneously, the displacement ring also is locked on the set collar by register pin, guarantee not rotate between set collar and the displacement ring, shown in Fig. 2 a, because the regulating ring inside thread is different with the pitch of outside screw, between displacement ring and the set collar axial displacement takes place, shown in Fig. 2 b, the pitch of establishing the inside thread of the outside screw of regulating ring and set collar is d 1, regulating ring inside thread and displacement ring outside screw be d 2, then regulating ring whenever rotates a circle, and shown in Fig. 2 c, the displacement ring is d with respect to moving of set collar 1-d 2, when regulating ring rotation n was all, the axial displacement between displacement ring and the set collar was Z=n (d 1-d 2); As seen, axial displacement between displacement ring and the set collar and d 1, d 2Irrelevant, only relevant with the pitch difference of the two screw threads of regulating ring, therefore, this regulating device can be according to the requirement of physical strength with d 1And d 2That does is very big, as long as d 1With d 2The very little micrometric displacement of just realizing of pitch difference regulate.
Advantage of the present utility model is: a kind of micrometric displacement regulation device of the present utility model, adopt two engage thread, pitch difference by two screw threads is realized trickle and accurate adjusting, because it is very big that two pitch can be done, therefore, this micrometric displacement regulation device is handling ease not only, and can improve the serviceable life of screw thread, and the micrometric displacement that has solved under cryogenic conditions or the vacuum condition is regulated.
The purpose of this utility model, feature and advantage will be illustrated in conjunction with the accompanying drawings by preferred embodiment.

Embodiment
With reference to accompanying drawing, will be described in detail specific embodiments of the present invention.
Embodiment 1
The embodiment that the utility model micrometric displacement regulation device is used for cryomicroscope.The measuring junction of a kind of cryogenic magnetic field microscope as shown in Figure 3 (can be used for for example measurement of human heart magnetic signal or material Non-Destructive Testing etc.), its sensitive detection parts are a kind of superconducting quantum interference device, must under extreme low temperature, work, therefore, sensitive detection parts can only be installed in the low-temperature measurement container.Because this sensitive detection parts are near more apart from measurand, sensitivity and spatial resolution are high more, so the measuring method across chamber wall that adopts greatly reduces sensitivity and spatial resolution usually.
Present embodiment adopts two screw thread roll-setting gears, as shown in Figure 3, wherein, the set collar 4 of two screw thread roll-setting gears is connected with low-temperature (low temperature) vessel outer wall 7 bottoms, displacement ring 1 is connected with probe microscope window ring flange 9 by O-ring seal 8, and an end of corrugated tube 6 is connected with displacement ring 1, and the other end is fixed on the bottom of low-temperature (low temperature) vessel outer wall 7, guarantee displacement ring 1 telescopic moving vertically, do not rotate with regulating ring 3.In the present embodiment, sensitive detection parts 11 are installed in 12 bottoms, low-temperature measurement vessel liquid chamber, the diameter of regulating ring 3 is 170mm, and the diameter of window ring flange 9 is 100mm, d 1Be 1.5mm, d 2Be 1.75mm, rotate regulating ring 3 with reference to the indication of the index dial 5 scribed on set collar 4, drive the flexible of detection window 9, degree of regulation is equivalent to 0.7 micron of every degree, is easy to realize the fine adjusting between sensitive detection parts 11 and the detection window 9.
For reducing to be detected the distance of thing and sensitive detection parts, detection window is made of ultra-thin materials usually.The device that this example provides makes can be approaching to greatest extent between sensitive detection parts and the measuring object, the sensitivity and the spatial resolution of detection system have greatly been improved, simultaneously, after measuring end, detection window can be adjusted on the position enough far away, be avoided low-temperature measurement container inner wall 10 because expanded by heating causes the damage of detection window.
Because detection window inside be vacuum, window flange disc area is bigger, bear great atmospheric pressure, and the physical strength of pitch is also had very high requirement, and is quite difficult by the adjusting of tens microns of common unit realizations even several micrometer ranges.
