The stud passes through the through hole to be connected with the nut. According to the utility model, the Sensor board is arranged on the fixing board; the stud and the nut are used to adjust the distance between the fixing board and the substrate, so that the distance between the Sensor board and a core lens is adjusted; through the elastic variable of the elastic piece, the Sensor board can be firmly fixed at an adjustment position; and through the focusing mechanism, the Sensor board can be easily adjusted to the focus position, so that an image is clear and stable.
Description
Technical field
The utility model belongs to optical focusing field, relates in particular to a kind of focus adjusting mechanism.
Background technology
In contemporary optics lens design, focus adjusting mechanism is mainly used in adjusting the position of optical pickocff (Sensor), makes in its focus in camera lens, ensures that lens imaging is clear and stable.
When camera photography, the picture of receiving on camera lens projects to the Sensor being fixed on Sensor plate, then sends out, and the focal length of camera lens is certain, therefore the position of Sensor plate should be also certain.And existing common integrated camera is directly installed on Sensor plate on movement, the position of Sensor plate is non-adjustable, and after movement and Sensor plate are fixing, the imaging surface of Sensor and the imaging surface of camera lens are likely not coplanar, can cause image blurring when imaging; Or adopt between substrate and Sensor plate spring is set, utilize the elastic module of spring to regulate substrate and Sensor plate distance, but because each spring is separate, be difficult to be adjusted to substrate parallel with Sensor plate, and stuck phenomenon easily appears in spring, bring very big inconvenience to actual focus adjustment operation.
Summary of the invention
For the problem of prior art, the utility model provides that a kind of stepping is level and smooth, easy for installation, the focus adjusting mechanism of accurate positioning, and concrete scheme is as follows:
A kind of focus adjusting mechanism, comprises the substrate being arranged on movement, fixed head, the nut of fixing Sensor plate; Described substrate is provided with double-screw bolt; Described fixed head is provided with the through hole corresponding with double-screw bolt; Between described substrate and fixed head, be provided with the shell fragment that regulates substrate and fixed head distance; Described double-screw bolt is connected with nut through through hole.
Described shell fragment is fixed on the opposite end of substrate or fixed head.
Being shaped as of described shell fragment is arc.
Described substrate is provided with lead, and described fixed head is provided with the pilot hole corresponding with lead.
Described double-screw bolt quantity is 2-4.
Preferably, described double-screw bolt quantity is 3.
The beneficial effects of the utility model: Sensor plate is arranged on fixed head, can carry out by double-screw bolt and nut the distance of adjustment fixing plate and substrate, thereby regulate the spacing of Sensor plate and movement camera lens, the elastic module that shell fragment has simultaneously can be fixed on Sensor plate adjusting position and can not become flexible; This focus adjusting mechanism makes Sensor plate more easily be adjusted to focal position, ensures the clear and stable of image.

Embodiment
In order to more fully understand technology contents of the present utility model, below in conjunction with specific embodiment, the technical solution of the utility model is further introduced and explanation.
Embodiment mono-
As shown in Figure 1-2, this focus adjusting mechanism comprises substrate 3, fixed head 4, Sensor plate 5, shell fragment 6; Substrate 3 is arranged on movement 1, and focus adjusting mechanism 2 is fixed on movement 1.
As shown in Figure 3-4, in the middle of substrate 3, be provided with camera aperture 34, two leads 33 are perpendicular to substrate 3 surfaces, be positioned on the substrate 3 of camera aperture 34 both sides, substrate 3 with lead 33 the same faces on be provided with three double-screw bolts 31, one of them is positioned at one end of substrate 3, two are positioned at the other end of substrate 3, three double-screw bolts 31 become isosceles acute triangle to distribute on substrate 3, utilize 3 principles that become face, and the convenient Sensor plate 5 that regulates is parallel with substrate 3; Being shaped as of shell fragment 6 is arc, is fixed on respectively the opposite end of substrate 3 by shell fragment fixed screw 61, and one of them shell fragment 6 is positioned on substrate 3 31 of two double-screw bolts outside at one end, and another shell fragment 6 is positioned on substrate 3 31 of double-screw bolts inner side at one end.
As shown in Fig. 5-6, Sensor52 is fixed on the front of Sensor plate 5, and FPC53 connects Sensor52, is positioned at the back side of Sensor plate 5; Circuit hole 43 is positioned in the middle of fixed head 4, and Sensor plate 5 is fixed on fixed head 4 by three fixed screws 51, and FPC53 is passed by circuit hole 43; Three through holes 41 on fixed head 4 are corresponding with the position of three double-screw bolts 31 on substrate 3; Two pilot holes 42 on fixed head 4 are corresponding with the position of two leads 33 on substrate 3.
When fixed head 4 is arranged on substrate 3, the double-screw bolt 31 on fixed head 4 is through through hole 41, by the distance between nut 32 adjustment fixing plates 4 and substrate 3; Lead 33, through pilot hole 42, only moves fixed head 4 along lead 33 directions.
Embodiment bis-
Shown in the focus adjusting mechanism of the present embodiment and embodiment mono-Fig. 2, the difference of focus adjusting mechanism is, described shell fragment 6 is fixed on the opposite end of fixed head 4, and the two ends of shell fragment 6 contact with substrate 3, and other structures are identical with embodiment mono-.
