Abstract
The invention discloses a camera zoom lens device which comprises an internal zoom rod and an external adjusting ring. The internal zoom rod is provided with a diaphragm blade and zoom adjusting grooves, the external adjusting ring is composed of two or more adjusting ring bodies, zoom adjusting protrusions are arranged on the inner side of the external adjusting ring, a lens holder is arranged in front of the external adjusting ring, a lens, an exposure hole and an auxiliary exposure hole are arranged on the lens holder, the exposure hole is formed in the middle of the lens, and the auxiliary exposure hole is formed near the exposure hole in the lens. The lens holder is externally provided with a rubber layer. Due to the fact that the two or more adjusting ring bodies are arranged on the outer side of the camera zoom lens device, the adjusting ring bodies can be detached one by one when the focal distance is too large so that the focal distance can be adjusted to a proper position, and the adjusting ring bodies can be added one by one when the focal distance is too small so that the focal distance can be adjusted to a proper position; meanwhile, the auxiliary exposure hole is added, and thus the exposure can be effectively increased.
Description
Technical field
The present invention relates to a kind of camera dolly camera device.
Background technology
Camera can allow time picture stop because of it, remembers fine moment that we want and welcomed by the people, opens the photograph album of time and can't help feeling a warmth and happy in the time that everybody is old.But existing camera often can be because the time shutter be long or too short, focal distance is inappropriate and affect the phase tablet quality of camera photograph.
Summary of the invention
The technical problem to be solved in the present invention is to be to realize a kind of camera dolly camera device, and this device can rationally regulate the time shutter, and can very conveniently regulate efficiently exposure focal length, makes camera take the very picture of high-quality.
For addressing the above problem, the present invention adopts following technical scheme: a kind of camera dolly camera device, comprises built-in expansion link and external regulating ring; Described built-in expansion link is provided with light hurdle blade and telescopic adjustment ditch, described external regulating ring is made up of two or more regulating rings, described external regulating ring inner side is provided with telescopic adjustment projection, described external regulating ring front is provided with lens mount, on described lens mount, be provided with camera lens, exposure hole and auxiliary exposure hole, described exposure hole is positioned at the centre position of camera lens, and described auxiliary exposure hole is positioned near the exposure hole on camera lens.
As preferably, described built-in expansion link and external regulating ring are Telescopic metal bar and the external regulating ring of metal.
As preferably, described lens mount is outside equipped with one deck rubber layer.
As preferably, the diameter of described exposure hole is greater than the diameter in auxiliary exposure hole.
The invention has the beneficial effects as follows: because this camera dolly camera device is provided with two or more regulating rings in outside, in the time that focal length is long, can pull down one by one regulating ring, make focal length be transferred to correct position, in the time that focal length is too short, can increase one by one regulating ring, make focal length be transferred to correct position, increase an auxiliary exposure hole simultaneously, can effectively increase exposure.
Brief description of the drawings
Fig. 1 is the stereographic map of a kind of camera dolly camera of the present invention device.
Fig. 2 is the stereographic map of another angle of a kind of camera dolly camera of the present invention device.
Embodiment
Consult shown in Fig. 1 and Fig. 2, a kind of camera dolly camera device, comprises built-in expansion link 10 and external regulating ring 8; Described built-in expansion link 10 is provided with light hurdle blade 1 and telescopic adjustment ditch 2, described external regulating ring 8 is made up of two or more regulating rings 3, described external regulating ring 8 inner sides are provided with telescopic adjustment projection 4, described external regulating ring 8 fronts are provided with lens mount 9, on described lens mount 9, be provided with camera lens 5, exposure hole 6 and auxiliary exposure hole 7, described exposure hole 6 is positioned at the centre position of camera lens 5, and described auxiliary exposure hole 7 is positioned near the exposure hole 6 on camera lens 5.
Described built-in expansion link 10 and external regulating ring 8 are the built-in expansion link of metal and the external regulating ring of metal, and described lens mount 9 is outside equipped with one deck rubber layer, and the diameter of described exposure hole 6 is greater than the diameter in auxiliary exposure hole 7.
The invention has the beneficial effects as follows: because this camera dolly camera device is provided with two or more regulating rings in outside, in the time that focal length is long, can pull down one by one regulating ring, make focal length be transferred to correct position, in the time that focal length is too short, can increase one by one regulating ring, make focal length be transferred to correct position, increase an auxiliary exposure hole simultaneously, can effectively increase exposure.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection domain of the present invention.
