Described zoom lens comprises change times assembly, compensation assembly.Described change times assembly, the coaxial setting of compensation assembly also are connected with relative zoom adjusting part simultaneously.Described change times assembly is arranged to become in times support tube by Zoom lens and constitutes; Described compensation assembly is arranged in the compensation support tube by offset lens and constitutes.
Described zoom lens also can comprise focusing component, and described focusing component is arranged at and becomes times assembly one side or be arranged at compensation assembly one side.
Described relative zoom adjusting part can be hand structure or electrodynamic type structure; Its hand structure comprises change times rotating cylinder, main tube, guide pin, and a described change times rotating cylinder is socketed on outside the main tube, is connected with master's tube is rotatable, and main barrel has guide hole, becomes times rotating cylinder and is connected with change times assembly and compensation assembly simultaneously by the guide pin that is positioned at guide hole.
The guide hole of described main barrel is the spiral guide hole, and a described change times rotating cylinder inboard has axial channel, becomes times rotating cylinder and is connected with change times assembly and compensation assembly simultaneously by the guide pin that is positioned at described axial channel and spiral guide hole simultaneously; By becoming the rotation of times rotating cylinder, its axial channel is stirred guide pin and is moved along the spiral guide hole of main barrel, and the change that is connected with guide pin times assembly and compensation assembly also move axially along main tube simultaneously, thereby carry out zoom.
The guide hole of described main barrel also can be axial straight hole, and the medial surface of described change times rotating cylinder is provided with helical guide groove, becomes times rotating cylinder and is connected with change times assembly and compensation assembly simultaneously by the guide pin that is positioned at described helical guide groove and axial straight hole simultaneously; By becoming stirring of times rotating cylinder, its helical guide groove is stirred guide pin and is moved along the axial straight hole of main barrel, and the change that is connected with guide pin times assembly and compensation assembly also move simultaneously vertically, thereby carry out zoom.
Described focusing component comprises focusing lens, focusing support tube, outer seal, and the focusing support tube is threaded with main tube, and outer seal is threaded with the focusing support tube, and focusing lens is pressed abd fixed in the focusing support tube.
Action principle of the present utility model is: the optical zoom camera of this band USB interface is taken by zoom lens, and when picture was determined, the scene size that is ingested changed with lens focus; Focal length is big, and the scene domain that is ingested is little, and scene image is big; Otherwise focal length is little, and the scene domain that is ingested is big, and scene image is little; In the focal length change process, image quality is constant.
The relative prior art of the utility model has following advantage and effect: the optical zoom camera of this band USB interface has increased optical zoom function on the camera basis of existing band USB interface, reference object blur-free imaging that can be different to distance, the shooting effect that makes camera is near relatively large video camera shooting effect, shooting quality with respect to existing camera is greatly improved, also significantly better than the shooting effect with electronics change camera doubly.
