At present, at the in-process of physical teaching, the mr can demonstrate the relevant experiment of parallel light to the student, consequently just can use this physical equipment of parallel light source frame, but current parallel light source frame does not have any protection device, and this contact that just leads to parallel light source frame to receive external force can damage, and current parallel light source frame also has not the way to change different multiple camera lenses to show more experimental results simultaneously.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the shortcoming that the parallel light source frame that exists now can't change different multiple camera lenses among the prior art, and a zoom camera lens and optical equipment that provide.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a zoom camera lens and optical device, the on-line screen storage device comprises a base, the horizontal rigid coupling of base upper surface has the spout, spout one side rigid coupling has the support, support top rigid coupling has the sliding sleeve, rotatable dwang of installing in the sliding sleeve, visual window has been seted up at the sliding sleeve top, the coaxial line rigid coupling has the driving gear on the dwang one end, the rotatable screw rod of installing in sliding sleeve bottom, the coaxial line rigid coupling has driven gear on one end of screw rod, driven gear meshes is in on the driving gear, the interval rigid coupling has a plurality of nut seats on the screw rod, nut seat bottom rigid coupling has the zoom camera lens, zoom camera lens bottom rigid coupling has the slider, slider slidable connects in the spout.
Preferably, the base bottom surface is equipped with the lift landing leg, the lift landing leg includes double-screw bolt and internal thread pipe, the vertical rigid coupling of double-screw bolt is in on the base bottom surface, the internal thread pipe spiro union is in on the double-screw bolt.
Preferably, the bottom of the internal thread pipe is fixedly connected with a sucker.
Preferably, a knob is coaxially and fixedly connected to the end part of the rotating rod.
The utility model provides a pair of zoom lens and optical equipment, beneficial effect lies in: this zoom camera lens and optical device can drive the dwang through the rotating knob and rotate, the turned angle that can observe the dwang through visual window when the dwang rotates, the dwang rotates can electronic driving gear and rotates, the turned gear rotates and drives driven gear and rotate, driven gear rotates and drives the screw rod and rotate, the screw rod rotates and drives nut seat along screw rod axial displacement, because the spiral pitch of every nut seat screw thread is different, can change the interval between the nut seat when the screw rod rotates, thereby change the interval of two adjacent zoom camera lenses, the change of zoom camera lens interval can lead to final light source projected distance to change, thereby realize zooming of camera lens.
