Abstract
The utility model discloses a lighting red dot star finder, comprising a lens barrel structure provided with an object lens set and a telescope ocular lens set. The wall of the lens barrel close to the telescope ocular lens set is provided with a star finder partition set. The lighting red dot star finder is characterized in that the a first partition plate and a partition seat are arranged in the lens barrel of the star finder partition set in cooperation; the partition seat is provided with a second partition plate in cooperation; and red light emitting diodes are respectively fixedly arranged below the first partition plate and the second partition plate. According to the utility model, the structure is simple, the cost is low, usage is convenient, the arrangement of adjusting screws on the movably arranged partition seat and the wall of the lens barrel of the star finder are convenient for the position adjustment of the second partition, through the bell mouths arranged on the first partition plate and the second partition plate of the star finder and the light emitting diodes arranged below the first partition plate and the second partition plate, a user can lock an object rapidly and conveniently under a poor-light condition, and eye fatigue of the user is prevented.
Description
Technical field
The utility model belongs to the telescope technical field, relates in particular to red some finder of illumination that a kind of astronomical telescope is used.
Background technology
The heavy caliber telescope is because multiplying power is high; the visual field is little to cause searching particularly difficulty relatively during Celestial Objects of object observing; usually can be visible the little mouth mirror of external is set on the glasses lens barrel; low range; the finder of large visual field; be used for searching celestial body to be observed; existing finder mostly is refraction type; the general employing two the separation or cemented objective; bore is generally about 2-5 centimetre; about 3 ° of visual fields; magnification is about 6～10 times; the graticule for calibration is equipped with at the place, focal plane; graticule is generally by the capable distribution of " ten " word; center target in the selected primary telescope range of observation is adjusted screw and is made graduation " ten " word center overlap this type of finder process and assemble relative complex with object observing; cost of manufacture is higher; in addition, owing to being in light darker night when observing starry sky, the observation of finder division line is difficulty; easily cause eye fatigue, affect the searching of object observing.
Summary of the invention
For the technical matters that exists in the prior art, the utility model purpose be provide a kind of simple in structure, cost is low, processing is easy to use, can convenient and swift red some finder of illumination that searches out target.
The utility model is realized by the following technical programs:
Red some finder of described illumination, comprise the primary telescope mechanism that is provided with objective lens and telescope ocular group, near pegging graft on the lens barrel wall of telescope ocular group one end finder graduation group is set, it is characterized in that being equipped with the first graticule and graduation seat in the described finder graduation arrangement of mirrors cylinder, be equipped with the second graticule in the described graduation seat, the below of described the first graticule and the second graticule is fixedly installed respectively red light emitting diodes.
Red some finder of described illumination is characterized in that described the first graticule and the second graticule all adopt transparent material PMMA eyeglass.
Red some finder of described illumination is characterized in that described the first graticule and the second graticule center are provided with bellmouth, and the diameter of described bellmouth is 0.6-0.8MM.
Red some finder of described illumination, it is characterized in that being spirally connected on the described finder lens barrel is provided with set screw, and described set screw and described the second graticule are used in conjunction with.
Red some finder of described illumination is characterized in that apical grafting is provided with spring between described graduation seat and the finder.
The utility model is simple in structure, cost is low, easy to use, the movable graduation seat that arranges and the setting of seeking star lens barrel wall adjusted screw, the position of convenient the second graticule is adjusted, by the bellmouth that arranges on finder the first graticule and the second graticule and the light emitting diode that is arranged on two graticules below, also lock onto target quickly and easily of dim light makes things convenient for the user in the situation that can prevent user's eye fatigue again.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is red some finder structural representation of the utility model illumination;
Among the figure: 1-objective lens, 2-set screw, 3-graduation group, 4-power switch, 5-telescope ocular group, 6-the first graticule, 7-the second graticule, 8-graduation seat, 9-spring, 10-red light emitting diodes, 11-wire.
Embodiment
Below in conjunction with Figure of description the utility model is described in further detail, and provides embodiment.
As shown in the figure, red some finder of the utility model illumination, comprise lens barrel mechanism, the front end of lens barrel mechanism is provided with object lens and rents 1, the tail end of lens barrel mechanism is provided with telescope ocular group 5, near the red some finder of pegging graft on the lens barrel wall of 5 one ends behind the telescope, finder arranges graduation group 3, be equipped with the first graticule 6 and graduation seat 8 in graduation group 3 lens barrels, be equipped with the second graticule 7 in the graduation seat 8, the below of the first graticule 6 and the second graticule 7 is fixedly installed respectively red light emitting diodes 10, red light emitting diodes 10 is electrically connected with power supply by wire 11, the first graticule 6 and second stroke of change plate 7 all adopt transparent material PMMA eyeglass, and the center of two differentiation plates is provided with bellmouth, the diameter of bellmouth is 0.6-0.8 MM, the surface of PMMA eyeglass is the light face, the light that red light emitting diodes 10 sends enters eyeglass and produces total reflection, graticule does not produce ruddiness, the bellmouth that is in the center of lens position is uneven surface, light is mapped to bellmouth and produces diffuse reflection, and red bright round dot can be seen in the center of lens position; The first graticule 6 is fixedly installed in the finder cylinder, and the second graticule 7 is equipped with on the graduation seat 8 of activity, and graduation seat 8 can radially move in the finder cylinder by the spring 9 of its apical grafting setting; The set screw 2 that is spirally connected on the finder lens barrel and arranges is used for controlling the second graticule 7 and moves up and down in the finder lens barrel, is used for seeking object observing.
During operation, by the selected object observing of telescope, target is in the center of range of telescope, power-on switch 4, adjusting set screw 2 positions makes 2 emitting red light points and selected object observing in the finder be in a straight line, the optical axis of red some finder of throwing light on this moment is parallel with telescopical optical axis, and the position of the red some finder that throw light on is namely adjusted and finished closed electrical source switch 4; Power-on can be quickly and easily by telescopic observation behind the finder lock onto target during use.
