Technical field
The present invention relates to mechanical field, be specifically related to a kind of burnt device that chases after.
Background technology
In the capture video process, (relate generally to two aspects: one is to rotate the camera lens focusing ring to focus, and another is the continuous variation of focusing position in a camera lens owing to the needs that focuses such as picture design and scene do not stopped change.) camera lens is directly operated, can bring a lot of inconvenience.At this moment chase after burnt device and just play important effect.Chase after burnt device and drive the camera lens focusing through a whole set of toothed gearing.Chase after the handle that revolves on the burnt device when we rotate, revolve, drive the outside burnt gear that chases after through bearing again and rotate drive the running of internal gear device through bearing.Chase after the gear ring of installing on burnt gear and the zoom lens and cooperate, rotate the operation of focusing thereby drive camera lens.
Existing shortcoming and the weak point that chases after burnt device structural principle existence: 1. do not have AB spacing, look for focus need use the stroke line pretty troublesome.2. the internal gear device is not integrated, and gear cooperates link too much with being connected of axle, and in use, rotation torsion is excessive, is very easy to cause coming off of gear and axle, thereby influences serviceable life.And tolerance clearance can be bigger.3 existing chase after focal plane plate and fix with the ball spring device, and dismounting is effort relatively.
Based on above reason, invent the burnt device that chases after of a kind of easy to use, durable, convenient disassembly, be assistant officer's problem to be solved in the present technique field.
Summary of the invention
For overcoming deficiency of the prior art, the object of the present invention is to provide a kind of burnt device that chases after, solved and existingly chase after burnt device and focus that time-consuming trouble, serviceable life are short, the problem of dismounting effort.
For solving the problems of the technologies described above, reach above-mentioned technical purpose, the present invention adopts following technical scheme:
A kind of burnt device that chases after of the present invention; Comprise and revolve handle; Revolve the focal plane plate that chases after that axially is connected with said; With said clamp and the scale plate that chases after the parallel veneer placement of focal plane plate, connects successively; The gearbox-case that links to each other with said scale plate, the sliding support plate that links to each other with said gearbox-case and be fixed on the latch segment on the said sliding support plate, the said front that chases after focal plane plate and a said reverse side that revolves through be installed in said chase after the iron hoop on the focal plane plate and be installed in said revolve to be connected the suction between the last magnet fix; Being provided with through draw-in groove of said AB backing pin clamp is stuck in spacing backing pin of A and the spacing backing pin of B on its side; The said inside of burnt gear through axle and said gearbox-case that chases after couples together; The inside of said gearbox-case is provided with two integral shafts that cooperatively interact.
Preferably, spacing backing pin of said A and the spacing backing pin of B fasten through screw and said AB backing pin fastening lock respectively.
Preferably, said revolve on 4 magnet are installed.
Preferably, said sliding support plate is fixed on the gearbox-case through screw.
Preferably, be provided with step above the said sliding support plate and cooperate, fix with screw thread pressure head and lock-screw, and can be free to slide with groove on the latch segment; Be provided with 2 screws above the said latch segment, be locked with the first locking spanner and the second locking spanner respectively, and the said first locking spanner and the second locking spanner can 360 the degree rotation adjusting.
Preferably, two close-fitting integral shafts that said gearbox-case inside is provided with, it is with burnt maximum rotation gap＜1 °.
Compared with prior art, of the present inventionly chase after burnt device advantage and be:
1. of the present inventionly chase after burnt device, on clamp, adopt the spacing backing pin design of AB, when needing the locking focus, just be locked, make in the operating aspect more convenient and quicker with the screw above the backing pin; When not required, do not influence use yet.
2. the internal gear that chases after burnt device of the present invention adopts the incorporate design of axle, cooperates more precision, and is littler with burnt gap.Durable more.
3. faster convenience is dismantled in the design and installation that focal plane plate adopts magnet to cooperate with iron hoop that chases after that chases after burnt device of the present invention.
