Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of spectrometer, concretely is a kind of integrated excitation head for spectrometer. BACKGROUND

[0002] In spectrometer, excitation head is important component, the product to be detected is placed on excitation head and is excited, the spectrum generated is sent into optical chamber by lens and reflector, for some mobile spectrometer, excitation head is installed on handheld gun, Figure 1 For the head structure of existing handheld gun, its excitation head is split structure, lens installation position is at the A of Figure 1 When needing to install or replace lens, the lower excitation head is first taken down, after lens is installed in place, the lower excitation head is installed, and the lens mounting plate is fixed using nut and screw, it is more cumbersome to operate, and efficiency is low. SUMMARY

[0003] To solve the above technical problem, the utility model provides a kind of integrated excitation head for spectrometer, it can simplify assembly operation, improve efficiency.

[0004] Its technical scheme is as follows: a kind of integrated excitation head for spectrometer, it includes excitation head shell, its characterized in that, the excitation head shell is integrated structure and one side is provided with installation slot, the lens mounting plate is embedded in the installation slot, the step through-hole is formed in the lens mounting plate, and the lens is installed in the step through-hole.

[0005] Further characterized in that, one end of the lens mounting plate is provided with connecting block, the installation through-hole is formed in the connecting block, the recess is formed in the excitation head shell and matched with the connecting block, and the threaded hole is formed in the recess and matched with the installation through-hole;

[0006] The excitation head shell includes cylindrical shell, the excitation head mounting hole is formed in the cylindrical shell, the sidewall of the cylindrical shell is connected with optical path transmission seat, and the installation slot is formed in one side of the optical path transmission seat.

[0007] After using the utility model, the originally split excitation head is changed into integrated structure, the lens is arranged on the lens mounting plate and inserted into installation slot, can be conveniently replaced, installation is simplified, it is convenient to use, and efficiency is improved.
