Abstract

The utility model provides double-adjusting filter rings, which comprise a conventional pressure ring-type filter ring and a direct pressure-type filter ring mounted on the pressure ring-type filter ring. According to the traditional pressure ring-type filter ring, the pressure ring is used for fixing the filter, the pressure ring presses the filter tightly at the filter end in a screw rotation mode, and a certain thickness is increased due to the screw and the pressure ring. According to the direct pressure-type filter ring, the filter is directly mounted inside the filter ring, the filter is fixed inside the filter ring in a punching mode, the distance between the filters is greatly reduced due to no thickness of the pressure ring and the screw, dark angles of a photo can be prevented from increasing due to the over long distance between the filters, and the problem that the filter is not suitable to be applied to a wide angle lens can be avoided. In addition, as the two rings can rotate independently, application of different glass combinations can be increased. Gradient gray, circular polarizer and the like require rotation to achieve the idea image effect.

Description

A kind of dual modulated type filter ring

[technical field]

The present invention relates to the filter ring, particularly a kind of dual modulated type filter ring of a kind of photograph or camera system.

[background technology]

In digital vedio recording and digital photographing process, in order to obtain picture or screen preferably, need use extraneous filters such as wide-angle lens, UV mirror, polariscope, using most filter T-Ring at present is COMPRESSIONTYPE mirror ring, namely comprise picture frame, be installed in the filter in the picture frame, and for the pressure ring that filter is pressed in the picture frame; The filter ring links together by lens mounts and camera or video camera, by regulating the filter ring, reaches the optimized image effect during use.

Development along with photography, camera technique, requirement to relevant camera lens auxiliary products such as filter is also more and more higher, single filter can not be satisfied the demand, dual modulated type filter ring also produces thereupon like this, the practice commonly used is to add the ring of plugging at COMPRESSIONTYPE mirror ring again, plug into to encircle and add a filter again, can reach two purposes of transferring like this, but, distance in the filter ring of this dual modulated type between two filters is too big, picture frame thickness increases, and has increased the dark angle of photograph, is not suitable for using in wide-angle lens.

[utility model content]

The utility model provides a kind of dual modulated type filter ring, increases, increased the dark angle of photograph, the technical matters that is not suitable for using to solve above-mentioned filter picture frame thickness in wide-angle lens.

In order to solve the problems of the technologies described above, the utility model provides a kind of dual modulated type filter ring, comprises lens mounts and the COMPRESSIONTYPE mirror ring that is connected on the described lens mounts, is also connecting a direct press type mirror ring on the described COMPRESSIONTYPE mirror ring.

Described direct press type mirror ring and described COMPRESSIONTYPE mirror ring link are provided with the groove of ccontaining eyeglass.

Be set to the annulus boss on the circle in the link of described COMPRESSIONTYPE mirror ring and direct press type mirror ring, be set to toroidal cavity on the corresponding cylindrical of described direct press type ring; Be set to the annulus boss on the circle in the link of described camera lens abutment ring and COMPRESSIONTYPE mirror ring, be set to toroidal cavity on the corresponding cylindrical of described COMPRESSIONTYPE ring.

By impact style eyeglass is fixed in the groove of ccontaining eyeglass in the described direct press type mirror ring.

Described COMPRESSIONTYPE mirror ring and described lens mounts link are provided with the groove of ccontaining eyeglass, and the top of described groove is provided with internal thread.

Also comprise a pressure ring, described pressure ring is provided with the external thread with described groove internal thread coupling, and the mode that rotatably compresses by pressure ring a chain for binding criminals line in the groove of ccontaining eyeglass in the described COMPRESSIONTYPE mirror ring is fixed eyeglass.

The interior circle of the opposite end of the ccontaining eyeglass of described direct press type mirror ring is provided with screw thread.

The excircle of described COMPRESSIONTYPE mirror ring and direct press type mirror ring is provided with anti-skidding line.

Because the dual modulated type filter ring that the utility model provides except the COMPRESSIONTYPE filter ring that comprises a routine, has also been installed a direct press type filter ring at COMPRESSIONTYPE filter ring; Traditional COMPRESSIONTYPE filter ring, owing to be to fix filter by pressure ring, even with the mode of pressure ring by screw thread rotation, at the filter end filter is compressed, because screw thread and pressure ring structure, pressure ring and screw thread can increase a part of thickness; Direct press type filter ring is directly filter to be installed in the filter ring, mode by punching press is fixed on filter in the filter ring then, and there is not the thickness of pressure ring and screw thread, reduced the distance between the filter greatly, avoided between the filter long-distance to cause that the dark angle of photograph increases and is not suitable for using in wide-angle.

In addition, be set to the annulus boss on the circle in the link of COMPRESSIONTYPE mirror ring and direct press type mirror ring, be set to toroidal cavity on the cylindrical of described direct press type environmental facies correspondence; COMPRESSIONTYPE filter ring and direct press type filter ring just can be adjusted respectively like this, reach two purposes of transferring.

In addition, because the interior circle of the opposite end of the ccontaining eyeglass of direct press type mirror ring is provided with screw thread; Other camera lens use can be used for plugging into.

In addition, because the excircle of COMPRESSIONTYPE mirror ring and direct press type mirror ring is provided with anti-skidding line; Increase people's finger and the friction between the mirror ring in use, be convenient to the adjustment of filter.

The dual modulated type filter ring that the utility model provides provides many rotatable mirror rings, increases the filter diversity; Dicyclo can rotate the utilization that can increase different glass combination alone, because for example gradual change ash or circle property polaroid, must rotate just and can reach desirable image effect.
