Abstract
The utility model discloses a digit lens module group, mainly comprising a lens, a regulating ring, an elastic device and a base. The lens is matched with the regulating ring through the thread; the elastic device is arranged between the regulating ring and the base. The inner edge of the lower part of the regulating ring is formed with bumps which are matched with the regulating groove of the base. Because the lens and the regulating ring are matched through the thread, the flatness of the lens is higher than the flatness of the regulating ring; the regulating ring and the base are matched directly through the bumps on the inner edge of the lower part of the regulating ring and the regulating groove of the base; the regulating groove has the function of positioning in the axial direction on the regulating ring; the elastic device between the regulating ring and the base has an up force on the regulating ring, which can eliminate the gap between the bumps on the inner edge of the regulating ring and the regulating groove on the base. The whole is evenly forced. In the regulating of the regulating ring, the movement of the lens relative to the base is stable and the occurrence of the inclination is reduced to the lowest.
Description
Technical field
The utility model relates to a kind of digital-mirror head mould group.
Background technology
Visible on the market at present digital-mirror head mould group, as shown in Figure 1, it is mainly by a camera lens 1 ', two regulating rings 2 ', 2 ", pedestal 3 ' and at least two springs 4 ' form; camera lens is placed in regulating ring 2 ', 2 " back links together camera lens 1 ' and pedestal 3 ' by spring 4 ', camera lens 1 ' and pedestal 3 ' are employing projections 11 ' and the cooperating of groove 31 '; And on regulating ring 2 ', be provided with inclined-plane 21 ', and camera lens 1 ' is provided with protruding grain 12 ', and rotating adjustment ring 2 ', camera lens 1 ' relative pedestal 3 ' are made axial linear movement, realize remote and in-plant switching with this.
But in the camera lens module of said structure, its parts are more relatively, and the axial location of camera lens realizes by spring, because the unbalance stress of each spring makes camera lens produce easily, and influences image quality; And camera lens and the connected mode of pedestal are to adopt cooperating of projection and groove, owing to be accurate instrument, so it is high that each planar light slippery that cooperates requires, and in the actual process, be difficult for processing desirable smooth flat, therefore can influence the flatness and the stationarity of camera lens, be the factor that influences image quality equally.
The utility model content
The purpose of this utility model provides moving accurately steadily of a kind of simple in structure, camera lens, and the digital-mirror head mould group of assembling easily.
For achieving the above object, solution of the present utility model is: digital-mirror head mould group, mainly comprise camera lens, regulating ring, elastic device and pedestal composition, and wherein camera lens and regulating ring are to pass through threaded engagement; Be provided with elastic device between regulating ring and the pedestal, regulating ring below inner edge forms projection; This projection cooperates with the regulating tank of pedestal.
The regulating tank of described pedestal is one " L " type fluting, and forms the table top of at least two height, between each table top by chamfered transition.
Periphery one side of described regulating ring is provided with the gear groove; Between the gear groove by chamfered transition.
The respective notch groove is provided with backstay on the described pedestal.
The groove of corresponding elastic device inner edge is provided with the protruding grain in location on the described pedestal.
After adopting such scheme, because camera lens and regulating ring are by threaded engagement, then the flatness of camera lens relative adjustment ring is higher; Regulating ring is directly matched with the regulating tank of pedestal by the projection on the inner edge of regulating ring below with pedestal, regulating tank has the effect of an axial location to regulating ring, elastic device between regulating ring and pedestal has an acting force that makes progress to regulating ring, can eliminate the gap between the regulating tank on regulating ring inner edge projection and the pedestal.Evenly when adjusting regulating ring, the motion between the relative pedestal of camera lens is steady for its integral body stressed, and it is minimum that the generation of tilt phenomenon can reduce to.

Embodiment
As shown in Figure 2, camera lens module of the present utility model is made up of camera lens 1, regulating ring 2, pedestal 3 and elastic device 4;
Be provided with one group of optical element in the camera lens 1, its top is provided with step 11, and its below is provided with external thread 12;
The inner edge that is provided with internal thread 21, regulating ring 2 lower ends in the regulating ring 2 forms three projections 22, and outer rim one side of the below of regulating ring 2 is provided with gear groove 23, and the side that is provided with two gears, 231,232, two gears in gear groove 23 is the inclined-plane setting;
Corresponding three above-mentioned projections 22 are provided with three reeds 41 on elastic device 4, also are provided with the groove 42 with pedestal 3 location on its inner rim; To avoid it to rotate relative to pedestal 3;
Three projections 22 of corresponding regulating ring 2 are provided with three " L " type regulating tanks 32 on the cylinder 31 of pedestal 3, form two table tops 321,322 in the regulating tank 32, between the two by inclined-plane 323 transition; Groove 42 at the corresponding elastic device 4 of the bottom of cylinder 31 outer rim is provided with the protruding grain 33 in location; The gear groove 23 of corresponding regulating ring 2 is provided with backstay 34 on pedestal 3 simultaneously.
As shown in Figure 3, during combination, the groove 42 of elastic device 4 is aimed at the protruding grain 33 of pedestal 3, and projection 22 cooperates in the regulating tank 32 of " L " type that screws in pedestal 3 again, the backstay 34 of pedestal 3 is combined together with gear groove 23, again camera lens 1 is screwed together in the regulating ring 2.
Pull regulating ring 2, when its relative pedestal 3 relatively rotates, because contacting of the varying mesa of the projection 22 of regulating ring 2 and the regulating tank 32 of pedestal 3 makes regulating ring 2 drive camera lenses 1 along the optical axis direction moving linearly.Elastic device 4 has an acting force that makes progress at this, can eliminate the gap of regulating ring 2 and pedestal regulating tank 32, its integral body stressed evenly, then the motion between the camera lens 1 relative pedestal 3 is steady, the image quality height of camera lens 1 then, when projection 22 contacted with table top 321, backstay 34 was positioned in the gear groove 231, and the distance between elongation camera lens 1 and shooting thing is to realize wide-long shot; When projection 22 contacted with table top 322, backstay 34 was positioned in the gear groove 232, and the distance between shortening camera lens 1 and shooting thing is to realize shooting at close range.
