Description
Technical field
The utility model relates to camcorder technology fields, more particularly to a kind of video camera easily focused.
Background technique
Focal length refers to the distance between eyeglass and photosensitive part in video camera or camera.Video camera needs to adjust before shipment
Save the focal length of camera lens.In the prior art, camera lens is inserted in the casing of video camera, and is fixed by bolt, and camera lens is caused
In lens position be it is fixed, focal length can not be adjusted.Also, lock bolt process is relatively complicated, and packaging efficiency is low.
Utility model content
The technical problems to be solved in the utility model is to provide one kind according to above-mentioned the deficiencies in the prior art and easily focus
Video camera, lens position can be moved, and then realized and focused function.
The technical solution of the utility model is as follows:
A kind of video camera easily focused includes casing, camera lens and focusing ring；The casing front surface is provided with
Casing, described sleeve pipe inner wall are provided with internal screw thread；The camera lens includes lens barrel and the eyeglass that is installed in lens barrel, the lens barrel
Outer wall is provided with external screw thread；The focusing ring inner wall is provided with internal screw thread；The lens barrel is inserted in described sleeve pipe and screw thread connects
It connects, the focusing ring is sheathed on outside the lens barrel and is threadedly coupled, and the focusing ring is butted on described sleeve pipe front end.
Further, the focusing ring outer wall is provided with the non-slip groove of spacing setting.
Further, the casing includes front shroud and rear cover, described sleeve pipe be set to the front shroud front surface and with institute
It states connection, the rear cover inside front shroud and is installed on the front shroud after-opening.
Further, the front shroud is provided with the connecting hole through the front shroud front surface, the rear cover front surface setting
Have a standpipe, the standpipe inner wall is provided with internal screw thread, and bolt passes through the connecting hole and is threadedly coupled with the standpipe, make it is described after
Lid is installed on the front shroud after-opening.
Compared with prior art, the utility model has the following beneficial effects: (1) first adjusts position of the focusing ring on lens barrel
It sets, then lens barrel is screwed in sleeve, the depth of lens barrel insertion casing can be limited by adjusting ring, and then is realized and focused function；
(2) easy to operate, it is easy to operate, improves packaging efficiency；(3) front cover and back cover composition, structure is simple, production cost
It is low.

Specific embodiment
It is practical new to this below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Type is described in further detail.
As shown in Figure 1-3, embodiment provided by the utility model, a kind of video camera easily focused, include casing
10, camera lens 20 and focusing ring 30.
10 front surface of casing is provided with casing 11, and 11 inner wall of casing is provided with internal screw thread.Camera lens 20 includes 21 He of lens barrel
The eyeglass 22 being installed in lens barrel 21,21 outer wall of lens barrel are provided with external screw thread.30 inner wall of focusing ring is provided with internal screw thread.Wherein,
In the present embodiment, 10 front surface of casing is provided with left and right two casings 11 arranged side by side, is mounted on camera lens 20 in two casings 11.Two
Camera lens 20 is adjustable at different focal lengths, obtains respectively to far and near image.
Lens barrel 21 is inserted in casing 11 and is threadedly coupled, and focusing ring 30 is sheathed on outside lens barrel 21 and is threadedly coupled, focusing
Ring 30 is butted on 11 front end of casing.
30 outer wall of focusing ring is provided with the non-slip groove 31 of spacing setting.Wherein, non-slip groove 31 can be improved user's hand with
Frictional force between focusing ring 30 realizes antiskid function, user is facilitated to rotate focusing ring 30.
Casing 10 includes front shroud 12 and rear cover 13, casing 11 be set to 12 front surface of front shroud and with connect inside front shroud 12
Logical, rear cover 13 is installed on 12 after-opening of front shroud.
Front shroud 12 is provided with the connecting hole 14 through 12 front surface of front shroud, and 13 front surface of rear cover is provided with standpipe 15, standpipe
15 inner walls are provided with internal screw thread, and bolt passes through connecting hole 14 and is threadedly coupled with standpipe 15, opens after so that rear cover 13 is installed on front shroud 12
Mouthful.
Focusing ring 30: (1) being set in outside lens barrel 21 by the application method of the present embodiment, rotation focusing ring 30 and then adjusting tune
Position of the burnt ring 30 on lens barrel 21；(2) lens barrel 21 is screwed in casing 11, as lens barrel 21 constantly protrudes into casing 11, is adjusted
Burnt ring 30 also moves closer to 11 front end of casing, and focusing ring 30 is finally butted on the depth that 11 front end of casing limitation lens barrel 21 is inserted into casing 11
Degree, focal length has been adjusted to suitable size at this time.
Above disclosures are merely preferred embodiments of the utility model, the utility model cannot be limited with this certainly
Interest field, therefore equivalent variations made according to the claim of the utility model still fall within the scope of the utility model.
