Abstract
The utility model relates to a guide rail type focusing mechanism for cameras, which comprises a lens board, a driving mechanism and a guiding mechanism, wherein, the driving mechanism comprises a focusing threaded rod which is connected with a threaded sleeve on the lens board by one end, and the other end is connected to a focusing shaft through a gear. The guiding mechanism comprises a guide post which is in slide connection with the lens board through a guide sleeve on the lens board, and the driving and the guiding mechanisms are symmetrically arranged at both ends of the lens board. The utility model achieves purpose that the lens board can accurately, parallelly and easily move backward and forward in the process of focusing, ensures the focusing consistence of every mirror head, and ensures the imaging quality of a high resolution lens of a stereo camera. Simultaneously, the utility model has the advantages of more convenient operation and comfortable focusing effect on hand, due to the upper shift of a focusing handwheel.
Description
The utility model relates to a kind of camera focus adjusting mechanism, especially relates to a kind of focus adjusting mechanism that a plurality of camera lenses are arranged on stereocamera.
Focus adjusting mechanism is in order to guarantee that the camera lens imaging is clear and be provided with.The kind of focus adjusting mechanism is a lot of in the prior art, and cam drive is arranged, gear drive, various ways such as screw thread transmission.
Stereocamera has a plurality of camera lenses, in order to guarantee the same moved further of each camera lens in the focusing process, a plurality of camera lenses all is fixed on the lens board, realizes accurate focusing.Because stereocamera is the stereocamera of large stretch of width of cloth particularly, its volume is big, and weight is big, most focus adjusting mechanisms that adopt gear, tooth bar transmission.Though this focus adjusting mechanism load-bearing is big, more firm, exist volume also big simultaneously, weight is also big, the defective that focusing power is also big.And the focusing tooth bar generally is installed in camera bottom, so focusing handwheel often is in the camera bottom, and the focusing operation is convenient inadequately under some occasion.
The purpose of this utility model is to overcome defective of the prior art, and a kind of guide tracked focus adjusting mechanism is provided, and makes the focus adjusting mechanism miniaturization, and the focusing operation is easy and convenient, and makes focusing handwheel be in the first half of camera.
The utility model has adopted following technical scheme to realize its purpose:
In the guide tracked focus adjusting mechanism of the camera that gear train and guiding mechanism constituted that comprises lens board and be connected with lens board, described gear train comprises focusing screw, swivel nut on this focusing screw one end and the lens board is and is rotationally connected, and the other end then is rotatably connected with the focusing axle by gear; Described guiding mechanism comprises guidepost, and this guidepost is and is slidingly connected by being placed in orienting sleeve on the lens board and lens board, and described gear train and guiding mechanism place the lens board two ends to be symmetry shape.
The utility model adopts technique scheme, has realized camera in the focusing process, and lens board can be accurate, parallel, forward and backward mobile like a cork, guarantees each camera lens focusing consistance, thereby guarantee the high-resolution image quality of stereocamera camera lens.Simultaneously, the focusing handwheel position of this mechanism is in the middle and upper part of camera, and is easy to operate, and the focusing comfortable feel is adapted at the focusing operation of various photography occasions.
Accompanying drawing is the utility model structural representation.
The utility model will be further described below in conjunction with accompanying drawing and embodiment.
With reference to accompanying drawing, the guide tracked focus adjusting mechanism of camera that the utility model is related, it comprises lens board 1 and the gear train and the guiding mechanism that are connected with lens board 1, this gear train and guiding mechanism place lens board 1 two ends to be symmetry shape.
Described gear train comprises focusing screw 2, and the swivel nut 3 on these focusing screw 2 one ends and the lens board 1 is and is rotationally connected, and the other end then is rotatably connected with focusing axle 10 by gear.This focusing screw 2 is connected with camera body by bearing 11, and this focusing axle 10 is connected with camera body by bearing 12.The gear 9 of focusing screw 2 one ends is a cone gear, and this cone gear 9 is meshed with cone gear 8 on the focusing axle 10.
Described guiding mechanism comprises guidepost, and the guidepost described in the present embodiment is a guide rail 6, and an end of this guide rail 6 is fixedlyed connected with camera body.Lens board 1 is and is slidingly connected by settling thereon orienting sleeve and lens board 1.Described orienting sleeve comprises a bearing 5 that is fixedly connected on the turning rolls 4 on the lens board 1 and is connected with this turning rolls 4.The facade of this turning rolls 4 is vertical substantially with the facade of lens bracket, is equipped with three on the turning rolls 4 with head bearing 5.The upper end of turning rolls 4 is parallel in the present embodiment is equipped with two bearings 5, and the lower end is equipped with a bearing 5, and this three bearings 5 are upper and lower to be clamped in and to be parallel mobile connection status on the guide rail 6, constitutes the travel mechanism of running vehicle type.
Camera described in the utility model embodiment is five stereo camera machines, and camera lens is installed on the lens board, and an end of focusing axle also is equipped with a focusing handwheel 7.Rotate focusing handwheel 7, focusing axle 10 drives focusing screw 2 by cone gear 8,9 and rotates, and does forward and backward parallel moving thereby drive lens board 1 on guide rail 6, thereby realizes the focusing operation of camera.In order to improve the reliability of mechanism, adopt left and right symmetrical structure form, i.e. two cover guiding gear trains.By adjusting, can guarantee the depth of parallelism requirement of lens board and camera focal plane, realize accurately focusing.
In sum, because the utility model adopts technique scheme, therefore have transmission and put down Surely, net synchronization capability is good, precision is high, the advantage such as easy to operate, is suitable for large size camera, and is outstanding It is that many lens stereo cameras use.
