Abstract
The utility model discloses a lens module group, mainly comprises a lens, a focus-regulating ring, an elastic device and a base. The focus-regulating ring is connected with the base through the elastic device. The lower part of the focus-regulating ring is formed with a regulating groove and bumps corresponding to the regulating groove are formed on the base. The lens is matched and fixed with the focus-regulating ring through the thread. Because the lens and the focus-regulating ring are matched through the thread, the flatness of the lens is higher than the flatness of the focus-regulating ring; the focus-regulating ring is connected with the base through the elastic device and the elastic device has the function of positioning in the axial direction on the base and the focus-regulating ring, the whole of which can be evenly forced. In regulating the focus-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 camera lens module that is applied to digital camera.
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 focusing rings 2 ', 2 ", pedestal 3 ' and at least two springs 4 ' form; camera lens is placed in focusing 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 focusing ring 2 ', be provided with inclined-plane 21 ', and camera lens 1 ' is provided with protruding grain 12 ', rotation focusing ring 2 ', and camera lens 1 ' relative pedestal 3 ' is made axial linear movement, realizes 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 camera lens module of assembling easily.
For achieving the above object, solution of the present utility model is: a kind of camera lens module, mainly comprise camera lens, focusing ring, elastic device and pedestal composition, wherein be connected by elastic device between focusing ring and the pedestal, its focusing ring below forms regulating tank, to should forming salient point by regulating tank on pedestal, and camera lens and focusing ring are to pass through threaded engagement.
Form the table top of two height in the regulating tank of described focusing ring, two table tops are by chamfered transition; Outer the placing of focusing ring is provided with projection, and elastic device is provided with the claw of spacing block set.
Form on the described pedestal and the fixing grab of elastic device; Corresponding elastic device is provided with hole clipping.
After adopting such scheme, because camera lens and focusing ring are by threaded engagement, then the flatness of the relative focusing ring of camera lens is higher; Focusing ring is connected by elastic device with pedestal, the effect that elastic device has an axial location to pedestal and focusing ring, and evenly when adjusting focusing 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, focusing 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 periphery that is provided with internal thread 21, focusing ring 2 belows in the focusing ring 2 form three protruding, piece 22, and the lower end of focusing ring 2 is provided with regulating tank 23, is provided with two table tops 231,232 in regulating tank 23, between the two by inclined-plane 233 transition (cooperating shown in Figure 4); The bottom of focusing ring 2 is made as the socket part 24 that is socketed on pedestal 3
Corresponding three above-mentioned projections 22 are provided with three claws 41 on elastic device 4, also are provided with the fixed orifice of fixing with pedestal 3 42 on it;
Corresponding regulating tank 23 is provided with salient point 31 on the pedestal 3, also forms the grab of fixing with elastic device 4 32 (cooperating shown in Figure 5) on it, and the middle part of pedestal 3 is the socket part 24 of mesopore seat with socket focusing ring 2.
As shown in Figure 3, during combination, camera lens 1 is screwed together in the focusing ring 2, three projections 22 of focusing ring 2 are stuck in three claws 41 of elastic device 4, the socket part 24 of the bottom of focusing ring 2 is socketed in the mesopore seat of pedestal 3, and the grab 32 of pedestal 3 is fastened in the fixed orifice 42 of elastic device 4, and salient point 31 is to place in the regulating tank 23 of focusing ring 2 on the pedestal 3 simultaneously.
Pull focusing ring 2, when its relative pedestal 3 relatively rotates, elastic device 4 fixing down because contacting of the varying mesa of the salient point 31 of pedestal 3 and focusing groove 23 makes focusing ring 2 drive camera lenses 1 along the optical axis direction moving linearly.Elastic device 4 has the effect of an axial location at this, and evenly then the motion between the camera lens 1 relative pedestal 3 is steady for its integral body stressed, and it is minimum that the generation of tilt phenomenon can reduce to, then the image quality height of camera lens 1.
