Further, the power interface of the headlamp be set to the pedestal on, headlamp by the power interface with
External power connects.
Further, the headlamp is incandescent lamp or LED light, other suitable lighting sources can also be used;Preferably
LED light.
Further, the glass lid is the glass lid made of insulating glass unit.
Further, heat emission hole, the heat emission hole communication groove and outside atmosphere are offered on the side wall of the groove, are used
In the heat dissipation of inside grooves.
Further, it is equipped with reflector below the headlamp;Reflector promotes the illumination of headlamp for improving light
Effect.
The utility model is had the following technical effect that compared with prior art using above technical scheme:
1) the utility model installs headlamp on the pedestal of titration folder, and headlamp provides enough light for titration process
According to operating personnel capable of being made insufficient or carry out titration experiments at night in illumination, due to there is enough illuminations, titration personnel can
Indicator discoloration is accurately judged, the operability and accuracy of titration experiments are improved.
2) glass lid of the utility model is the glass lid being made of insulating glass unit, and hollow structure has heat-insulated
Effect can avoid the fever of the headlamp below glass lid and be caused from then to the accuracy of drop reaction in the reaction vessel of top
It influences.

Specific implementation mode
The technical solution of the utility model is described in further detail below in conjunction with the accompanying drawings.
Referring to Fig. 1, a kind of titration stand of use for laboratory band illumination, including titration stand ontology, which includes bottom
Seat 4 and pillar 8 is connected with sliding cuff 7 on pillar 8, and sliding cuff 7 can slide up and down adjusting along pillar 8;Slide cuff 7
One end is connect with pillar 8, and other end connection titration folder 6, titration folder 6 clamps buret 5 and carries out titration operation, carries out titration operation
When, the underface of buret 5 is placed with conical flask 3, is installed on the pedestal 4 of the titration stand ontology below conical flask 3
Headlamp 9, headlamp 9 illuminate conical flask 3 upwards, and the variation of reaction color in conical flask 3 is observed convenient for user.
The power interface 2 of headlamp 9 is set on pedestal 4, and headlamp 9 is connect by power interface 2 with external power.
Referring to Fig. 2, in the present invention, headlamp 9 is mounted in the following manner on pedestal 4:In pedestal 4
On open up fluted 10, headlamp 9 is fixedly installed in groove 10, and the upper port of groove 10 is provided with glass lid 1, glass
Headlamp 9 is protected in inside groove 10 by lid 1, and the top surface of glass lid 1 is flushed with the top surface of pedestal 4.Wherein, glass cover
