Abstract

The utility model provides an eclectic cyclic zooming telescope comprising an optical lens. The device is characterized in that a connecting piece that is connected with the optical lens is positioned on the guide lever, and the guide lever is connected with the base on which a worm gear, a worm, a reducer and a motor are mounted. The connecting piece is connected with the worm gear by the connecting rod that is arranged on the connecting piece. By pushing the driving button of the motor, the utility model is possible to realize the cyclic adjustments of focusing without judgment advancing or retreating and setting the advance switch or retreat switch. The device not only features in simple operation, but also a much faster focusing speed. The utility model can conduct electric cyclic focusing of single body or combined body of objective lens, or prisms, or field lens or oculars of optical lens.

Description

Electronic circulation focusing telescope

Technical field

The utility model relates to a kind of telescope, especially a kind of electronic circulation focusing telescope.

Background technology

Existing telescope mostly is the mechanical focusing telescope greatly.During use telescope is put at the moment, and, after focusing, can sees observing object clearly with the whole telescopical focus adjusting mechanism of hand adjustment.Because manual focusing will be spent the long period and adjust repeatedly and just can see clearly, and is not only time-consuming, but also causes senses of discomfort such as kopiopia, hand acid, the soreness of waist, dizziness or order revolve easily, and usually can miss fleeting natural wonders.For this reason, the inventor applied for the patent of " electronic focusing telescope (patent No. CN200320115165.0) " in 2003.Though difficult problems such as time-consuming, the effort that has solved that manual focusing brings, but because the transfer arm in machinery and the circuit design has Stroke Control in moving, before pressing forwarding button transfer arm moved to forward behind the stop, must press back again can move backward, just must have in the design and advance, retreat mechanism and electric control gear, this kind structure can play good effect on accurate focusing, but need the operator to remember the mechanism present position in the operation, advance or retreat to differentiate next step operation.Its operation still requires further improvement.

Summary of the invention

Have the focusing operation inconvenience that electronic focusing telescope exists now for overcoming, the limited deficiency that waits of focusing speed, the utility model provides a kind of electronic circulation focusing telescope.

The utility model is realized by following technical proposal: a kind of electronic circulation focusing telescope, comprise optical lens, it is characterized in that the web member that links to each other with optical lens places on the guide rod, guide rod links to each other with the pedestal which is provided with worm gear, worm screw, speed reduction unit and motor, and web member links to each other with worm gear by the connecting rod on it.So that web member and optical lens are moved along guide rod, thus the adjustment of realization focal length.

Described connecting rod one end is fixed on the web member, and the other end is fixed on the excentric shaft of worm gear, so that rotatablely moving of worm gear become the straight reciprocating motion of connecting rod.

Described worm gear and worm screw are matched, and worm screw links to each other with train of reduction gears, and train of reduction gears links to each other with electric machine main shaft, so that under driven by motor, by the motion of train of reduction gears, worm screw, worm gear and connecting rod, the optical lens that promotes web member and two ends thereof moves.

Described optical lens is the monolithic entity or the assembly of object lens or prism or field lens or eyepiece.

The utility model compared with prior art has following advantage and effect: adopt such scheme, only need press motor driven switch, just can realize the circulation adjustment of focal length, need not to judge and advance or retreat, also need not to be provided with the switch and retreat switch of advancing, not only operation is simpler, and focusing speed is more quick, and the utility model can carry out electronic circulation focusing to the object lens of optical lens or the monolithic entity or the assembly of prism or field lens or eyepiece.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further, is not limited thereto but hold within the utility model.

The web member 8 that connects two optical lens 11 is a transfer arm, this transfer arm 8 places on the parallel guide rod 9, parallel guide rod 9 links to each other with pedestal 10, pedestal 10 is provided with worm gear 4, the worm screw 3 matched with worm gear 4, the train of reduction gears 2 that links to each other with worm screw 3, the motor 1 that links to each other with train of reduction gears 2, be fixed with connecting rod 6 by axle 7 on the web member 8, the other end of this connecting rod 6 is fixed on the excentric shaft 5 of worm gear 4.Its course of work is: 1 rotation of energising rear motor, drive train of reduction gears 2 work simultaneously and obtain big retarding and compare power, gear set 2 drives worm screw 3 rotations, worm screw 3 drives worm gear 4 rotations, worm gear 4 horizontal frontal planes are provided with excentric shaft 5, and excentric shaft 5 drivening rods 6 will rotatablely move and change over linear reciprocating motion, and connecting rod 6 drives transfer arm 8 and carry out linear reciprocating motion on parallel guide rod 9, transfer arm 8 drives optical lens 11 and moves, thereby realizes the adjustment of circulation focal length.
