Description
Technical Field
The utility model relates to a spectrophotometer instrument field, specific saying is a halogen tungsten lamp stand with adjustable.
Background
The halogen tungsten lamp is an incandescent lamp filled with halogen elements or halide gases, and is widely used in optical instruments due to its characteristics of small volume, stable color temperature, etc. In the manufacturing process of the halogen tungsten lamp, lamp pins at two ends of a filament are directly sealed by a glass shell, so that the position of the filament relative to the glass shell is difficult to control.
The halogen tungsten lamp is used as a light source of a spectrophotometer, the position of a filament, namely a luminous point, of the halogen tungsten lamp needs to be ensured at the optimal position of an instrument and fixed relative to a monochromator of the instrument, and the light source needs to be replaced when the halogen tungsten lamp reaches the service life. Since the position of the tungsten filament, i.e. the light emitting point, of each halogen tungsten lamp is slightly different, random replacement may result in the light source being out of the optimal position of the instrument, which may affect the performance of the instrument.
The existing halogen tungsten lamp generally adopts a spring piece clamping structure, can be replaced only by means of tools, is inconvenient for users to operate and influences efficiency.
Therefore, it is necessary to design an adjustable lamp holder for halogen tungsten lamp.
Disclosure of Invention
The utility model discloses broken through prior art's a difficult problem, designed a halogen tungsten lamp stand with adjustable.
In order to achieve the purpose, the utility model discloses a halogen tungsten lamp stand with adjustable, including locating plate, riser, holder, spring leaf, lamp stand, halogen tungsten lamp, the lamp stand is fixed on the holder, is equipped with riser waist type hole on the riser, and the screw on the holder passes riser waist type hole, makes holder and riser sliding connection, and halogen tungsten lamp passes the riser and fixes on the lamp stand, is equipped with location waist type hole on the locating plate, and set screw passes location waist type hole, makes locating plate and riser sliding connection.
Two spring pieces are arranged on the clamping piece and tightly press the glass shell at the bottom of the halogen tungsten lamp.
The lamp pins of the halogen tungsten lamp are inserted into the insertion holes of the lamp holder.
The positioning plate is provided with a positioning hole and is fixed on the instrument through a knurled screw.
Rectangular holes are arranged on the vertical plates, and the halogen tungsten lamp passes through the rectangular holes and is fixed on the lamp holder.
Compared with the prior art, the utility model ensures that the luminous point of each halogen tungsten lamp is positioned at the best position of the instrument through the adjustable halogen tungsten lamp holder; when the light source is replaced, the old halogen tungsten lamp holder is screwed off manually, and the pre-calibrated halogen tungsten lamp holder is installed, so that the operation is convenient.
