Embodiment
As shown in Figure 2, in first embodiment of the present utility model, camera lens 100 comprises lens barrel 101 and mirror cell 102.It is cylindric that lens barrel 101 and mirror cell 102 all roughly are.Mirror cell 102 comprises first center pit 103, and eyeglass 104 promptly is embedded in first center pit 103.According to the quantity and the diameter of eyeglass 104, first center pit 103 can be the stepped hole that diminishes by rank, aperture minimum foremost wherein, and near the aperture maximum of lens barrel 101, with ease of assembly.Eyeglass 104 can be sphere or aspherical lens.
The rear end of 102 first center pit 103 is provided with internal thread 105 in the mirror cell.The path of this internal thread 105 is greater than the diameter of the other parts of first center pit 103.Lens barrel 101 comprises the barrel 106 of front end and the flange 107 of rear end, and is provided with second center pit 108.In the outside of barrel 106, be provided with external thread 109 with internal thread 105 engagements.When lens barrel 101 and mirror cell's 102 combinations, the rear end face of mirror cell 102 and flange 107 are fitted.
At the leading section of internal thread 105, be provided with first recess 110 that is used to escape burr away from flange 107.At barrel 106 front ends of lens barrel 101, second center pit 108 is provided with outside chamfering 111.First recess 110 is provided with first inclined-plane 112 that cooperates with it.When lens barrel 101 and mirror cell's 102 cooperations, first recess 110 will form the space between internal thread 105 and external thread 109, to hold a small amount of burr that may move to herein.And chamfering 111 moves to lens barrel 101 and 102 inside, mirror cell with avoiding these burr cooperating of first inclined-plane 112, and eyeglass 104 is polluted.
When internal thread 105 and external thread 109 engagements, the most of burr that produced can move to along with the precession of screw thread near flange 107 places.In order to hold these burr, at close flange 107 places, promptly 102 rearward end away from eyeglass 104 in the mirror cell are provided with second recess 113 that is used to escape burr between the inner peripheral surface of the outer peripheral face of lens barrel 101 and mirror cell 102, can avoid burr to move, eyeglass 104 is polluted.
