[embodiment]
Below in conjunction with accompanying drawing the present invention is further specified.
Please refer to Fig. 1 and Fig. 3, lens adjustment device 1 of the present invention comprises a main part, and the cavity of this main part 2 for caving inward forms a receiving space in the cavity, and the two ends of main part 2 respectively are provided with a circumferential notch 21.22.One lid 3 that matches with main part 2, lid 3 by screw closure in main part 2 on the surface of lower recess.
Please refer to Fig. 3, an eyeglass 6 is assembled in the receiving space, and it comprises first end and second end, also contains a cam adjustment mechanism 5 in the cavity, and cam adjustment mechanism 5 comprises cam 50, one shell fragments, 51, one nuts 52 and a lock-screw 53.
Cam 50 is an eccentric wheel, in cam edge one inclined-plane is arranged, and what first end of eyeglass tilted is resisted against on the inclined-plane.And first end of eyeglass has circular chamfering, and described chamfering is resisted against on the described inclined-plane to reduce cam when rotating and the friction between the eyeglass 6.Because cam 50 be eccentric wheel, when cam 50 rotates, but be resisted against an end upper and lower displacement of the eyeglass 6 on cam 50 inclined-planes, and then drive the eyeglass rotation.Described cam also is provided with a upwardly extending sleeve 500, and the top of sleeve 500 is provided with two openings 501, plays (not shown) rotating cam 50 usefulness for a flat mouthful screw.The outside surface of sleeve 500 is provided with screw thread 502, one nut is located on the sleeve 500 for 52 groups, be equiped with a shell fragment 51 between nut 52 and cam 50 upper surfaces, shell fragment 51 comprises that a described shell fragment 51 comprises a substrate and an elastic arm 511, described substrate is fixed between nut 52 and the cam 50, and described elastic arm 511 elasticity press on the described eyeglass 50.Sleeve 500 also is provided with a through hole, and lock-screw 53 is housed in the through hole of sleeve 500.
As Fig. 4 and Fig. 5, when needs were adjusted the angle of eyeglass 6, with the angle of bottle opener rotating cam 50, the angle of eyeglass 6 can change along with the rotation of cam 5 and change.When eyeglass 6 is adjusted to suitable angle, the screw 53 in the locking sleeve, the elastic arm 511 of shell fragment 51 compresses eyeglass 6, makes eyeglass 6 stationkeeping.
And because this lens adjustment device 1 is an independent assembly, this assembly can be installed on the laser instrument that needs the assembling Brewster window at any time, does not need original laser structure is carried out too big change.
As Fig. 6, when laser tube need be installed Brewster window, this lens adjustment device 1 breach 21 is assembled on the opening 71 of laser tube 7, and the opening 71 of laser tube is sealed mutually with the cavity of lens adjustment device 1, after the angle of adjustment eyeglass 6 cavity is sealed.Make lens adjustment device 1 and laser tube form the cavity of a sealing, these cavity two ends respectively are provided with an eyeglass 8.9, and one of them is arranged at the opening 72 of the laser tube other end, and another is arranged on another breach 22 of lens adjustment device 1.The common resonator cavity that forms laser instrument between two eyeglasses 8.9.
