Abstract
The utility model relates to a small-sized varifocal beam expanding lens, which belongs to a monitoring facility and comprises a support, a lens cone, an outer sleeve, an inner tube and a large lens, wherein a rear seat of the lens cone and the support are fixed with each other; the lens cone is in clearance fit with the outer sleeve; the outer edge of the outer sleeve is provided with a check ring to limit the outer sleeve; the lower wall of the lens cone is provided with a longitudinal through slot; the inner tube is in the clearance fit in the lens cone; the large lens is inlaid in the radial direction of the inner tube; the outer wall of the bottom of the inner tube is implanted into a pin shaft; the pin shaft is embedded into the through slot of the lens cone; a tail tube which is connected into a whole on a coaxial line with the rear seat of the lens cone passes through the support; a small lens is arranged in the tail tube and then is connected to an optical fiber head with an optical fiber laser; the optical fiber head and an inner ring of the tail tube are fixed and telescoped with each other; a motor is fixed at the lower part of the support; and an output transmission gear of the motor is meshed with a gear ring of the outer sleeve. The small-sized varifocal beam expanding lens disclosed by the utility model has a reasonable structural design, powerful functions, has a light spot homogenizing treatment function, can be used at night and in the day and has clear imaging and a far night vision distance; 24-hour all-weather monitoring is realized, and thereby, real remote imaging is realized.
Description
Technical field
The utility model belongs to monitor and control facility, particularly relates to a kind of mini-focal expander lens.
Background technology
In recent years, the monitoring field of China's every profession and trade is more and more higher to the requirement of night monitoring technology, and night monitoring and evidence obtaining have become the primary problem in each security protection of puzzlement, technical precaution field.The latrine pit evidence obtaining of current domestic public security, the counterreconnaissance at night of army's frontier defense coast defence, deploy troops on garrison duty the night in important base, and the night of oil field and pipe laying is antitheft, the night monitoring that the anti-light on airport disturbs, the monitoring line walking of no supervision snipe etc. have all pointed to new demand night vision monitoring field.But existing monitor has all adopted zoom lens, but the imaging wave band is confined in the visible-range, in the dark then can not imaging or image quality bad, can not recognize.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and a kind of mini-focal expander lens is provided.
Mini-focal expander lens of the present utility model is to be made of support, lens barrel, outer sleeve, inner core and big eyeglass.The back seat of lens barrel and support fix and clearance fit outer sleeve, outer cause ring washer outer sleeve is spacing.The lower wall of lens barrel is provided with vertically saturating groove, and the lens barrel internal clearance cooperates inner core, and inner core is the big eyeglass of Inlaid embedding radially, and the outer wall of going to the bottom of inner core is planted into bearing pin, and bearing pin embeds in the saturating groove of lens barrel.The tail pipe that is connected one with the back seat coaxial cable ground of lens barrel passes support, is provided with little eyeglass in the tail pipe, is connected with the optical fiber head that has fiber laser again, and the interior ring of optical fiber head and tail pipe fixes intussusception.Motor has been fixed in the bottom of support, and the output drive gear of motor is meshed with the gear ring of outer sleeve.
As further improvement of the utility model, described big eyeglass is to be interior prominent single convex lens in inner core.
As further improvement of the utility model, be embedded with a switch washer on the top of the gear ring of outer sleeve root.
As further improvement of the utility model, described motor is to replace with dc reversible electromotor.
Mini-focal expander lens of the present utility model, reasonable in design, powerful has hot spot homogenize processing capacity, all can use at night and daytime, it is clear to have an imaging, and night visual range is far away, realize the round-the-clock monitoring of twenty four hours, thereby realize the imaging of real remote zoom.Can be widely used in remote monitor, the correctional officer in the public security system, night secret collect evidence photograph, bank's defendance, the national treasury defence etc. of important goal, the occasions such as goods stacking at important place such as field facility, oil depot, border monitoring, harbour are monitored, are patrolled and examined.
Description of drawings
Figure of description 1 is the structural representation of mini-focal expander lens of the present utility model.
Embodiment
Mini-focal expander lens of the present utility model is to be made of support 1, lens barrel 2, outer sleeve 3, inner core 4 and big eyeglass 5.The back seat of lens barrel 2 and support 1 fix and clearance fit outer sleeve 3, outer cause ring washer 6 outer sleeve 3 is spacing.The lower wall of lens barrel 2 is provided with vertically saturating groove 7, and lens barrel 2 internal clearances cooperate inner core 4, and inner core 4 is the big eyeglass 5 of Inlaid embedding radially, and the outer wall of going to the bottom of inner core 4 is planted into bearing pin 8, and bearing pin 8 embeds in the saturating groove 7 of lens barrel 2.The tail pipe 9 that is connected one with the back seat coaxial cable ground of lens barrel 2 passes support 1, is provided with little eyeglass 10 in the tail pipe 9, is connected with the optical fiber head 12 that has fiber laser 11 again, and optical fiber head 12 fixes intussusception with the interior ring of tail pipe 9.Motor 13 has been fixed in the bottom of support 1, and the output drive gear 14 of motor 13 is meshed with the gear ring 15 of outer sleeve 3, is embedded with a switch washer 16 on the top of the gear ring 15 of outer sleeve 3 roots.
Mini-focal expander lens of the present utility model, its principle are that the dc reversible electromotor output gear drives the gear wheel rotation on the outer sleeve, realize that the camera lens zoom expands bundle thereby the bearing pin on helicla flute on the outer sleeve and then the drive inner core makes inner core move forward and backward.
