Holding frame, which includes lamp firm banking and the cover plate being matched therewith.It is characterized in that：The base includes fixed plate and hangs down
Straight two supporting walls and cathode modulation draw-in groove in fixed plate are constituted, and hollow out between two supporting walls, draw-in groove two ends setting two are convex
Platform, draw-in groove size are set according to the size of cathode modulation, and inwall is stained with one layer of soft rubber pad.Two supporting walls must be perpendicular to fix
Plate, draw-in groove centrage are located on two supporting walls line of symmetries and certain apart from fixed plate bottom surface distance.
Cover plate described in the utility model is set to the shape of arc-shaped slot and symmetrical two boss, and arc-shaped slot is in order to match somebody with somebody
Cathode modulation shape clamping cathode modulation is closed, two boss are more preferably engaged with base, arcuately draw-in groove is symmetrical for two boss, on the inside of arcwall face
It is stained with one layer of rubber blanket.
The boss of base draw-in groove left end described in the utility model is threaded hole installation hinge and is connected with upper lid.
The boss of base draw-in groove right-hand member described in the utility model is provided with the groove for installing Magnet.
The screwed hole of four installation fastening glue screws is provided with cover plate circular arc draw-in groove cambered surface described in the utility model.
Cover plate arc-shaped slot left end boss described in the utility model is provided with screwed hole and installs hinge.It is described in the utility model
Cover plate arc-shaped slot right-hand member boss arranges fluted installation Magnet.
The beneficial effects of the utility model are：Two supporting walls are exactly perpendicularly to base plate, according to response system focusing lens
Actual height carrys out the height of process support wall, makes the height of the centre-to-centre spacing base plate of draw-in groove be equal to focusing lens center to the height of base plate
Spend, and the diameter of draw-in groove is arranged according to using the diameter of cathode modulation, thus can be directly by cathode modulation from holding frame rear
It is inserted directly into and reuses four screws of cover plate and fix tight, it is possible to directly uses, it is to avoid adjust, and accuracy height.Work as experience
Special circumstances also can be opened cover plate dress from cover plate Magnet and take cathode modulation.This utility model has simple structure, convenient mounting and clamping, nothing
Need to adjust, be aligned accurately, without lamp body is hindered the advantages of.

Specific embodiment
Below specific embodiment of the present utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of cathode modulation holding frame for atomic fluorescence spectrometer of the present utility model, its bag
Lamp firm banking 1 and the cover plate 2 being matched therewith are included, spy is characterised by：Firm banking 1 includes base plate 3 and perpendicular to solid
Two supporting walls 4,5 of fixed board and cathode modulation draw-in groove 6 are constituted, hollow out between two supporting walls, and draw-in groove two ends setting two is convex
Platform, draw-in groove size are set according to the size of cathode modulation, and inwall is stained with one layer of soft rubber pad 7.4 top boss of supporting walls is threaded
Hinge 11 is installed and is connected with upper lid in hole.5 top boss of supporting walls arranges fluted 12 and installs Magnet
