[specific embodiment]
Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
Please refer to Fig. 4～6; The preferred embodiments of the utility model provides a kind of laser focus control 200, and this laser focus control 200 comprises focus lamp mount pad 230, is fixed in the focus lamp reducing sleeve 220 on the focus lamp mount pad 230 and is fixed in the focus lamp 210 on the focus lamp reducing sleeve 220 through threads turn.When focus lamp reducing sleeve 220 rotates around focus lamp mount pad 230, focus lamp reducing sleeve 220 will drive focus lamp 210 and move along focus lamp mount pad 230, thereby realize the function of focusing.Because when focus lamp reducing sleeve 220 rotates around focus lamp mount pad 230; Focus lamp mount pad 230 will be with respect to 220 motions of focus lamp reducing sleeve; The circular motion that is about to focus lamp reducing sleeve 220 converts rectilinear motion into, thereby realizes focus lamp 210 with respect to the fine setting of focus lamp mount pad 230 positions reaching the purpose of focusing, and in the focusing process; Focus lamp reducing sleeve 220 keeps more firm threaded connection relation with focus lamp mount pad 230; Focus lamp reducing sleeve 220 does not almost rock with respect to focus lamp mount pad 230, and therefore, this laser focus control 200 can be realized higher focusing accuracy.
Concrete; The focus lamp mount pad 230 of this laser focus control 200 comprises the installed surface 231 and connecting cylinder 232 that interconnects; The end of connecting cylinder 232 is provided with screw thread, is provided with the screw thread with the terminal threads engaged of connecting cylinder 232 in the focus lamp reducing sleeve 220.Focus lamp reducing sleeve 220 comprises the focus lamp adapter 221 of being located at focus lamp reducing sleeve 220 ends.This focus lamp adapter 221 is provided with scale, the connecting cylinder 232 of focus lamp mount pad 230 be provided with focus lamp adapter 221 on the scale that is used of scale.
Further, focus lamp reducing sleeve 220 whenever rotates a circle around focus lamp mount pad 230, and focus lamp reducing sleeve 220 moves 1 millimeter relative to focus lamp mount pad 230.Being focus lamp reducing sleeve 220 relies on the screw thread rotation that cooperatively interacts between them during one week with focus lamp 210 around focus lamp mount pad 230, focus lamp reducing sleeve 220 will be with focus lamp 210 along the Z that is indicated among Fig. 4 to moving 1 millimeter.Focus lamp reducing sleeve 220 is provided with 50 five equilibriums scale weekly, and connecting cylinder is provided with the scale of 1 millimeter spacing.Like this, when focus lamp 210 need to move a certain apart from the time, just can regulate accurately according to these scales, using will be very convenient.
This laser focus control 200 also comprises positioning knob 240.Focus lamp reducing sleeve 220 is provided with first shell fragment 222 and second shell fragment, 223, the first shell fragments 222 and second shell fragment 223 and is oppositely arranged, and first shell fragment 222 and second shell fragment 223 can be arranged on the focus lamp reducing sleeve 220 position near focus lamp adapter 221.First shell fragment 222 and second shell fragment 223 are provided with locating hole, and positioning knob 240 is fixed together first shell fragment 222 and second shell fragment 223 through this locating hole.Can be provided with screw thread on the positioning knob 240; When positioning knob 240 fixing first shell fragments 222 and second shell fragment 223; To pass first shell fragment 222 and second shell fragment 223 successively; Screw thread on the positioning knob 240 will cooperate with the locating hole on second shell fragment 223 and play fixation; Thereby make first shell fragment 222 and second shell fragment 223 clamp the connecting cylinder 232 of focus lamp mount pads 230, so that focus lamp reducing sleeve 210 is fixed on the focus lamp mount pad 230, the screw thread on the positioning knob 240 and first shell fragment 222 cooperate the degree of adjusting first shell fragment 222 and second shell fragment, 223 clamping connecting cylinders 232 with one of them locating hole on second shell fragment 223.The existence of positioning knob 240 can further guarantee the phenomenon that focus lamp 210 can not occur rocking, even under the situation of vibrations, rocking can not appear in focus lamp 210 yet, thereby further improves the precision of this laser focus control 200.Screw thread on the positioning knob 240 can play the effect of regulating first shell fragment 222 and 223 pairs of focus lamp mount pads of second shell fragment, 230 clamping degree.
In addition, the focus lamp installed surface 231 of this laser focus control 200 is provided with a plurality of installing holes 233 that are connected with other device.Being provided with of these installing holes 233 can make things convenient for this laser focus control 200 to be fixedly connected with other device.In the present embodiment; The focus lamp 210 of this laser focus control 200 is fixed together through the mode that is threaded with focus lamp reducing sleeve 220; Also can adopt alternate manner to be fixed together in other embodiments between focus lamp 210 and the focus lamp reducing sleeve 220, also can adopt the design of integral type.
When this laser focus control 200 needs focusing, at first loosening positioning knob 240, rotary-focusing mirror reducing sleeve 220 is to correct position then, the positioning knob 240 of screwing at last.Like this, these laser focus control 200 focusing finish.These laser focus control 200 employed parts are less, and therefore simple in structure, cost is low.In addition; Adopt the mode that is threaded between this focus lamp mount pad 230 and the focus lamp reducing sleeve 220; In the focusing process, remain the relation that is threaded between the two; Rock less guaranteeing that higher precision is arranged, thereby and this laser focus control 200 be converted into rectilinear motion through circular motion and realize regulating accurately focus lamp reducing sleeve 220, so this laser focus control 200 has higher focusing accuracy.
The above embodiment has only expressed several kinds of embodiments of the utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model patent should be as the criterion with accompanying claims.
