Problems solved by technology

[0007] The technical problem to be solved by the present invention is to provide a telescopic lens that can only increase the total height of the cam cylinder when the maximum zoom stroke needs to be increased in the prior art, and to provide an enlarged zoom lens that does not increase the overall height. Telescopic lens with thinner stroke

Embodiment Construction

[0036] The foregoing and other technical content, features and effects of the present invention will be clearly understood in the following detailed description of two preferred embodiments with accompanying drawings.

[0037] Before presenting a detailed description, it is noted that in the following description, similar components are denoted by the same numerals.

[0038] refer to Figure 4 , 5 , is the first preferred embodiment of the thinned telescopic lens that can increase the zoom stroke of the present invention. The thinned telescopic lens that can increase the zoom stroke can be telescopic and zoomed along the axial direction X, and includes: a base tube 10, a first The moving assembly 20 , the second moving assembly 30 , the rotary cylinder 40 , the driving assembly 50 , and the driven assembly 60 .

[0039] Such as Image 6 As shown, the base cylinder 10 has a cylinder wall 11, a plurality of first straight rails 12 arranged on the inner peripheral surface of t...

Abstract

The invention relates to a thin zoomer lens capable of increasing the zooming stroke. The thin zoomer lens comprises a base drum, a first moving combination, a second moving combination, a swing drum, a driving combination and a driven combination, wherein the first moving combination is arranged in the base drum and provided with a first straight-in drum, a first cam drum and a first lens group, the second moving combination is arranged in the base drum and provided with a second straight-in drum, a second cam drum and a second lens group, the swing drum is sleeved outside the base drum, the first and second cam drums are glidingly connected in an axial direction and move in the axial direction simultaneously, the driving combination and the driven combination respectively and independently drive the first and second moving combinations to enable the first and second straight-in drums to move respectively and independently in the axial direction, so that the zooming stroke between the first and second lens groups can be increased.

Description

technical field [0001] The invention relates to a lens, in particular to a thin telescopic lens capable of increasing the zoom stroke. Background technique [0002] Such as figure 1 , 2 Shown in , 3, is known a kind of telescopic lens that can telescopically zoom (Zooming) along an axis X, and this telescopic lens comprises base cylinder 1, the rotary cylinder 2 that is rotatably sleeved on the outside of this base cylinder 1, can The cam cylinder 3 rotatably arranged in the base cylinder 1, the first linear cylinder 4 which is slidably connected to the base cylinder 1 along the axis X and is co-movingly connected to the cam cylinder 3 along the axis X , is slidably connected to the base cylinder 1 along the axial direction X and is connected to the second linear cylinder 5 of the cam cylinder 3 along the axial direction X, and is slidably connected to the second linear cylinder 5 along the axial direction X. The first lens group 6 of the straight-forward barrel 4 and the...
