Abstract

The utility model provides a be used for square polariscopic rotary mechanism has the filter support, the filter support passes through fastener fixed mounting internal frame, the preceding terminal surface adaptation of internal frame is two -way 360 rotatory outer frames of internal frame relatively, the frame square polarizer of clamping piece fixed mounting of putting up. The utility model discloses realize the independent rotation function of other lenses on square polarizer is for the filter support, improved square polariscopic application range, satisfy the continuous rotation regulation's of square polarizer needs demand, reach the best result of use of square polarizer.

Description

For square polariscopic rotating mechanism

Technical field

The utility model belongs to photographic goods technical field, is specifically related to a kind of for square polariscopic rotating mechanism.

Background technology

In photography, it is reflective that polariscope is mainly used in elimination, improves saturation degree and the contrast of color, is one of filter commonly used in photography.Due to polariscope be often change camera angle after all need to carry out rotation adjustment, polariscope is all generally circular.Along with widely using of square filter support, use square polariscopicly also to get more and more.But because the structure of square filter support limit, square polariscope can only adjust in four orientation up and down, cannot realize continuous setup, significantly limit square polariscopic usable range in 360 ° of peripheries.Therefore, the problem solving square polariscopic continuous rotation adjustment is needed.Now propose to improve.

Utility model content

The technical matters that the utility model solves: provide a kind of for square polariscopic rotating mechanism, solve the continuous rotation problem of square polariscope at 360 ° of peripheries by the cooperation between inner frame, outside framework and intermediate plate.

The technical solution adopted in the utility model: for square polariscopic rotating mechanism, there is filter support, described filter support fixedly mounts inner frame by securing member, described inner frame front end face adaptation can relative to the two-way 360 ° of outside frameworks rotated of inner frame, and described outside framework fixedly mounts square polariscope by intermediate plate.

Described inner frame and outside framework are provided with restriction keeper in relative rotation.

Described inner frame rear end face is shaped with mounting hole, and is screwed and is arranged in filter support.

Described intermediate plate is fixedly installed in the outside surface of outside framework by screw, and described square polariscope is fixed on intermediate plate.

The utility model advantage compared with prior art:

1, the inner frame relatively rotated and outside framework enable the 360 ° of continuous rotation adjustment in periphery of square polariscope, overcome the defect that current square polariscope can only adjust relative to filter support in four orientation up and down, make square polariscopic function reach optimum efficiency.

2, one-piece construction is simple, is easy to realize, and has higher practical value.

Accompanying drawing explanation

Fig. 2 is the utility model structure left view;

Fig. 3 is the assembly structure schematic diagram of the utility model inner frame and outside framework.

Embodiment

Below in conjunction with accompanying drawing 1-3, a kind of embodiment of the present utility model is described.

For square polariscopic rotating mechanism, there is filter support 7, described filter support 7 is installed on camera lens, filter support 7 front end is by securing member fixed installation inner frame 1, particularly (as shown in Figure 2), described inner frame 1 rear end face is shaped with mounting hole, and is fixedly mounted in filter support 7 by inner frame 1 by screw 6.The adaptive outside framework 2 of described inner frame 1, and inner frame 1 and outside framework 2 are provided with restriction keeper 5 in relative rotation, during enforcement, described keeper 5 is preferably lock-screw, and the screw hole that namely lock-screw is shaped with by outside framework 2 bottom is screwed into.(as shown in Figure 3) described inner frame 1 is ring-shaped article, its excircle is fastened by concaveconvex structure and outside framework 2, and outside framework 2 can rotate relative to inner frame 1 360 ° of arbitrary continuations in periphery, further, the outer face of outside framework 2 is shaped with the screw for installing intermediate plate 4, after screw 3 and screw adaptation, intermediate plate 4 is fixedly installed in the outside surface of outside framework 2, afterwards square polariscope is inserted intermediate plate 4 until bottom along the installation direction of intermediate plate 4.

Principle of work: because inner frame 1 is fixed in filter support 7, drive the relative inner frame 1 of square polariscope to rotate to an angle in the scope of 360 ° by outside framework 2, locking fixture 5, prevents the rotational slide between inter and outer gimbal.Realize the independent spinfunction of square polariscope relative to other eyeglasses in filter support 7, improve square polariscopic usable range, meet the demand that square polariscope needs continuous rotation regulates, reach the best result of use of square polariscope.

Above-described embodiment, just preferred embodiment of the present utility model, is not used for limiting the utility model practical range, therefore all equivalence changes done with content described in the utility model claim, all should be included within the utility model right.
