Detailed description of the invention

With reference to Fig. 1～Fig. 9, this utility model is the core adjusting device of a kind of zoom lens, including retaining ring 6, retaining ring 6 is provided with two set levers 2 for locking barrel, retaining ring 6 is fixed on the driving assembly that can move along X-axis and Y-axis, and each set lever 2 is separately positioned on the orthogonal X-direction of optical axis and Y-direction。

The core adjusting device of this zoom lens, is made up of a retaining ring 6 and a pair set lever 2。Number of parts is few, and adjustment structure is little and simple, it is simple to management。Set lever 2 is arranged on the orthogonal X-direction of optical axis and Y-direction, allow to carry out aligning according to X-axis Y-axis displacement easily, during use, retaining ring is locked barrel, when adjusting X-direction or Y-direction, barrel moves with locking device simultaneously, avoid relative motion, it is prevented that scratch barrel surface, improve appearance yield。

As this utility model preferred embodiment, retaining ring 6 is equipped with locking salient point 64 on the position relative with each set lever 2。

As this utility model preferred embodiment, the end that abuts of set lever 2 is arcwall face 21。

As this utility model preferred embodiment, set lever 2 is by locking barrel with retaining ring 6 threaded engagement spiral。

As this utility model preferred embodiment, retaining ring 6 is fixed on driving assembly by support 3。

As this utility model preferred embodiment, support 3 is L-type。

Retaining ring is fixed by a support 3, and performance is more stable, and positioning precision is higher。

Example for the interior focusing-style Zoom lens cone of four groups of lens illustrates。As shown in Figure 1, first battery of lens 1 includes front side lens barrel 5 and rear side lens barrel, the front side lens barrel 5 of the first battery of lens 1 is locked by retaining ring 6 and two set levers 2 of core adjusting device, retaining ring 6 is provided with locking salient point 64, the side of the first battery of lens 1 abuts locking salient point 64 by two set levers 2, and be locked, set lever 2 is screwed in the internal thread hole 63 of retaining ring 6 by screw thread 22 and is fixed in retaining ring 6, the face 61 of retaining ring 6 contacts with stent cover 31, screw is through locking annular distance 62 and screwed hole 32, so that retaining ring 6 is fixed on support 3, support 3 is by being fixed on driving assembly and can along X, Y-direction moves, make core adjusting device along vertically moveable with optical axis by driving assembly to apply active force。It addition, rear side lens barrel is fixing relative to lens barrel retaining member。Thus, the first battery of lens 1 can be made along direction relative movement orthogonal with the optical axis relative to the second battery of lens, the 3rd battery of lens and the 4th battery of lens, thus front side lens barrel and rear side lens barrel being adhesively fixed and aligning can be carried out after making the first battery of lens 1 move to the position that optical property is best。The detection method of optical property desired positions generally uses by the mode of the contrast evaluation of estimate of the image shot by aligning lens。

Compared with prior art, the had adjustment structure parts of this utility model reduce, and cost reduces；High-precision aligning can be carried out；More reasonable structure is reliable, it is to avoid the original structure impact on outward appearance。

Structure of the present utility model is made up of a retaining ring 6 and a pair set lever 2。Parts are few, it is simple to management。Retaining ring is fixed by a support 3, performance is more stable, positioning precision is higher, locking mechanism fixing front side lens barrel 5, on front side of when adjusting X-direction or Y-direction, lens barrel moves with locking device simultaneously, front side lens barrel 5 is absent from relative motion with locking device, so avoiding the probability of scratch surface, it is thus possible to ensure not affect outward appearance。

Certainly, the invention is not limited to above-mentioned embodiment, those of ordinary skill in the art it may also be made that equivalent variations or replacement under the premise without prejudice to this utility model spirit, and these equivalent deformation or replacement are all contained in the application claim limited range。
