Abstract
The utility model discloses a lens focusing adjusting ring, which comprises a rack. One end of the rack is clamped on a first connecting block, and the other end of the rack is clamped on a second connecting block. An excessive part of the rack can pass through a groove in the first connecting block. The two connecting blocks are connected through a bolt. When the bolt is loosened, a different part of the other end of the rack is clamped on the second connecting block, and the lens focusing adjusting ring with different inner diameters can be obtained by screwing up the bolt so as to meet the requirements for assembling different vidicons or cameras. Therefore, the production cost of the vidicons or the cameras is effectively reduced. Moreover, when the adjusting ring is rotated, the connecting blocks can be pressed, so that the rotating radius can be increased, and the adjusting ring is convenient to adjust.
Description
Technical field:
The utility model relates to the lens focusing adjusting ring of a kind of video camera or camera.
Background technology:
Existing lens focusing adjusting ring mainly is made of the annulus of a closure, and the internal diameter of ring is fix nonadjustable, and during adjustable lens, tumbler ring just.Yet because the internal diameter of above-mentioned regulating ring is fixed, different video cameras or camera will be equipped with different lens focusing adjusting rings, will increase like this production cost of video camera or camera.And harder when above-mentioned regulating ring is regulated, it is not too convenient to regulate.
The utility model content:
The purpose of this utility model provides and a kind ofly convenient regulates, general lens focusing adjusting ring.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: lens focusing adjusting ring, it comprises tooth bar, one end of tooth bar is stuck on the first contiguous block, the other end is stuck on the second contiguous block, the part that has more can be passed the groove of the first contiguous block, and two contiguous blocks connect by the spiral shell select.
Wherein, the bottom end face of described first, second contiguous block is arcwall face.
Wherein, an end of described spiral shell select is connected with knob.
Wherein, described knob surface is provided with groove.
The beneficial effects of the utility model: unclamp the spiral shell select, the position that the tooth bar other end is different is stuck on the second contiguous block, tighten the lens focusing adjusting ring that the spiral shell select just can obtain different inner diameters, being fit to the assembling demand of different cameras or camera, thereby effectively reduce the production cost of video camera or camera.And, during rotating adjustment ring, can so just can increase radius of turn according to contiguous block, the convenient adjusting.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
With reference to Fig. 1, lens focusing adjusting ring, it comprises tooth bar 1, and an end of tooth bar 1 is stuck on the first contiguous block 2, and the other end is stuck on the second contiguous block 3, and groove 4, two contiguous blocks that the part that has more can be passed the first contiguous block connect by spiral shell select 5.Unclamp spiral shell select 5, the different position of tooth bar 1 other end is stuck on the second contiguous block 3, tighten the lens focusing adjusting ring that spiral shell select 5 just can obtain different inner diameters, being fit to the assembling demand of different cameras or camera, thereby effectively reduce the production cost of video camera or camera.And, during rotating adjustment ring, can so just can increase radius of turn according to contiguous block, the convenient adjusting.
In order to make things convenient for, this regulating ring to be installed on video camera or the camera securely, the bottom end face 6 of first, second contiguous block can be designed to arcwall face, to be fit to the periphery of video camera or camera.
In addition, in order to make things convenient for the rotation of spiral shell select 5, an end of described spiral shell select 5 is connected with knob 7.
Also have, described knob 7 surfaces are provided with groove 8, from being convenient to greatest extent the rotation of spiral shell select 5.
Certainly, the utility model is not limited to the above embodiments, is equal to the utility model or becomes bad technical scheme also to belong to protection domain of the present utility model.
