On body chamber wall, the gas chamber is internally formed the passage of light transmission, when gas analyzer light path regulating device 100 is along gas
When fluid chamber produces displacement, the position of the optical module in corresponding gas analyzer changes, in this way, reaching optical path adjusting
Purpose.
Specifically, the gas analyzer light path regulating device 100 includes：Regulation main structure 10, adjust auxiliary structure 20 with
And tightening structure 30.The auxiliary structure 20 of regulation is formed at one end of the regulation main structure 10, by the auxiliary knot of regulation
Apply the active force regulation regulation main structure 10 on structure 20, the relatively described gas compartment cavity wall of regulation main structure 10 can be made to produce position
Move, the direction of the displacement is along the axial direction of its own.Additionally, acting on the power source adjusted in auxiliary structure 20 along the tune
Save the radial direction of main structure 10.
Optical module 40 in corresponding gas analyzer is installed in the regulation main structure 10, and can be led with the regulation
Structure 10 is moved.
As shown in fig. 6, further, the light path regulating device 100 is threadingly attached in the cavity wall, the spiral shell
Line connection is a kind of form of connected mode of the present invention, and the present invention includes but is not limited to this mode, and the connected mode may be used also
Realized with by structures such as sliding block, guide rails.Used as one of which implementation method, the screw thread is interior on the light path regulating device
Screw thread, in present embodiment, the internal thread is formed inside the regulation main structure 10, and now, regulation main structure 10 is installed on
On the lateral wall of gas chamber.When regulation main structure 10 is driven by adjusting auxiliary structure 20, you can realize gas analyzer light
Slip of the road adjusting means 100 on the lateral wall of gas chamber.Respective optical component 40 is installed on the regulation main structure 10
On, when slip of the gas analyzer light path regulating device 100 on the lateral wall of gas chamber, it can be with gas analyzer light
Road adjusting means 100 is synchronized with the movement.So as to, during the shift in position of optical module 40, the light reflected by optical module 40
Reflection path also changes therewith, so as to reach the purpose of regulation light path.
Preferably, in above-mentioned implementation method, the regulation main structure 10 and gas chamber are cylinder, the main knot of regulation
Structure 10 is arranged at one end of the cylindrical gas chamber, and now, the optical module 40 is located at the light inside gas chamber
One end of transmission channel, the other end of the light transmission channel is again provided with optical module, optical module of the light at two ends
Between formed reflection.Alternately, regulation main structure 10 can also be installed on described gas chamber one end by slideway mode.
As shown in Fig. 2 used as another embodiment, screw thread is external screw thread, this embodiment party on the light path regulating device
In formula, the external screw thread is formed at regulation main structure 10 surface, and now, regulation main structure 10 is installed on the inner side of gas chamber
On wall, one end that auxiliary structure 20 is formed at the regulation main structure 10 is adjusted, and along the axial direction of the regulation main structure 10
Corresponding cavity wall end face is stretched on to set.Regulative mode is same as described above in present embodiment, and narration is not repeated herein.
It is another embodiment of the present invention, screw thread on the light path regulating device 100 as shown in Fig. 3, Fig. 7 (a)-(b)
It is external screw thread, in present embodiment, the external screw thread is formed at regulation main structure 10 surface.Now, regulation main structure 10 is pacified
On madial wall loaded on gas chamber, adjusting auxiliary structure 20 can be equal to the impetus for being formed at the regulation main structure 10
21, this implementation method is carried out in regulation using special " Γ " font instrument, so that the adjustment effect that " Γ " font instrument is produced
The direction of power is the radial direction of adjusting means 100.Regulative mode is same as described above in present embodiment, is not repeated to chat herein
State.
As shown in Figure 4,5, adjust in auxiliary structure 20 and be provided with impetus 21, can be to adjusting auxiliary structure by the impetus 21
20 apply active force, wherein, the power source of the impetus 21 is acted on along the radial direction of the regulation main structure 10.This is puted forth effort
Point 21 can be bulge-structure or pore structure or slot structure etc..The quantity of the impetus 21 and position set depending on concrete condition
Put, do not limit.
Specifically, the inner structure form of the impetus 21 is corresponding with the tool heads of respective standard instrument.So as to,
When being adjusted, optical path adjusting can be easily carried out under the auxiliary of conventional tool, without being limited by gas chamber's madial wall
System.Specifically, during regulation, the handle of standard workpiece is gripped, tool heads is engaged with impetus, conventional tool is applied to make
The active force of the regulation rotation of main structure 10, so that gas analyzer light path regulating device 100 produces the displacement on axial direction, and then
Optical module 40 is driven to produce corresponding displacement.
The tightening structure 30 is located at the side of the regulation main structure 10, is that the regulation main structure 10 provides fastening
Power, specifically, the tightening structure 30 holds out against structure or snap ring clasping structure for screw.In regulation, tightening can be loosened first
Structure 30, enters line slip, when optical module 40 moves to institute by standard workpiece control gas analyzer light path regulating device 100
After needing position, then the fastening adjustment main structure 10 of tightening structure 30 is controlled, protect the position of gas analyzer light path regulating device 100
Hold fixation, it is to avoid loosen.
In sum, gas analyzer light path regulating device of the invention is slideably positioned in the cavity wall of gas chamber, is entered
During row optical path adjusting, adjustment effect power is the limit in its chamber space of not being bullied along the power source of adjusting means radial direction
System, can continuously adjust to the light path in gas analyzer, only receive from being adjusted axially operation during regulation so as to be overcome
The defect of space limitation.
Additionally, after gas analyzer light path regulating device of the invention is adjusted to light path, can be protected by tightening structure
Keep steady solidity, advantageously ensures that the retentivity of optical element installment state after regulation, makes the performance of gas analyzer more.
