Thermal camera camera lens is thermally isolated in one kind
Technical field
The present invention relates to video camera, thermal camera camera lens is thermally isolated in more particularly to one kind.
Background technology
Traditional thermal camera is typically to detect the target to target heat condition in itself using infrared detector
Real-time status.This infrared detector is in itself to the unusual height of heat sensitivity.For the accuracy to target detection, to instrument
The interference of heat itself requires small, and this Design on thermal insulation to apparatus structure just proposes higher requirement.It is existing with reference to Fig. 1
Thermal camera camera lens include translucent cover housing 1 ', the infrared light board of transparent cover plate 2 ' 3 ' and camera lens 4 ', the transparent cover plate 2 '
On translucent cover housing 1 ', the infrared light board 3 ' is located between translucent cover housing 1 ' and camera lens 4 ', the part of camera lens 4 '
Through infrared light board 3 ' and located at the front of transparent cover plate 2 ', the other end of camera lens 4 ' is connected with video camera fuselage.But, this
Kind of structure has that sealing is poor, and the infrared detector on infrared light board is easy by ectocine, infrared when for a long time using video camera
Easily by video camera fuselage, heat itself is disturbed infrared detector on lamp plate so that image quality is not high;So that existing
Thermal camera can not meet aforementioned claim.Though the also high thermal camera of some image quality on existing market, it is tied
Structure is complicated, cost is high, hence it is imperative that exploitation is a kind of simple in construction, cost is low, work newly can be excellent infrared takes the photograph
Camera lens meet the market demand.
The content of the invention
Therefore, for it is above-mentioned the problem of, the present invention proposes that a kind of simple in construction, cost is low, cause thermal camera
Image quality is high, thermal camera camera lens is thermally isolated in good airproof performance.
To realize above-mentioned technical problem, the solution that the present invention takes is:Thermal camera camera lens is thermally isolated in one kind, bag
Translucent cover housing, transparent cover plate, infrared light board and camera lens, in addition to thermal insulation board are included, the transparent cover plate and translucent cover housing are close
Envelope connection, the infrared light board is located between translucent cover housing and camera lens, and described camera lens one end partially passes through infrared light board and set
In with front of transparent cover plate, the camera lens other end is connected with thermal insulation board, the thermal insulation board is provided with for camera lens and video camera machine
The through hole that body is connected.
Further, the sealed circle of the transparent cover plate is tightly connected with translucent cover housing, and sealing ring is tightly set in
The outer wall of bright cover plate.
Further, the thermal insulation board is additionally provided with heat sink in the one side the week side of boss of infrared light board.
By using preceding solution, the beneficial effects of the invention are as follows:By the way that translucent cover housing and transparent cover plate is close
Envelope connection, sets thermal insulation board between camera lens and fuselage so that thermal camera realization ensures imaging while working long hours
Quality is high, while sealing is strong, it is to avoid the infrared light board in thermal camera camera lens is by ectocine, and water resistance is high, with
Existing thermal camera camera lens is compared, and thermal camera camera lens of the invention has production cost low, simple in construction, row
Interference except fuselage to camera lens, substantially increases thermal camera image quality;By further setting, i.e., in thermal insulation board
One side the week side of boss close to infrared light board is provided with heat sink so that the heat Quick diffusing on infrared light board, further increases
The heated interference of infrared detector, substantially increases the performance of thermal camera on infrared light board, can wide popularization and application.
Brief description of the drawings
Fig. 1 is the decomposed structural representation of existing thermal camera camera lens;
Fig. 2 is the decomposed structural representation of the embodiment of the present invention.
Embodiment
In conjunction with the drawings and specific embodiments, the present invention is further described.
With reference to Fig. 2, one kind disclosed in the embodiment of the present invention is thermally isolated thermal camera camera lens, including translucent cover housing 1, thoroughly
Bright cover plate 2, infrared light board 3, camera lens 4, thermal insulation board 5, sealing ring 6 and heat sink 7, the sealed circle 6 of the transparent cover plate 2 with it is transparent
Over body case 1 is tightly connected, and sealing ring 6 is tightly set in the outer wall of transparent cover plate 2;The infrared light board 3 is located at translucent cover housing 1
Between camera lens 4, described one end of camera lens 4 partially pass through infrared light board 3 and located at the front of transparent cover plate 2, the camera lens 4 is another
End is connected with thermal insulation board 5, and the thermal insulation board 5 is provided with the through hole 51 being connected for camera lens 4 with video camera fuselage, the thermal insulation board
5 are additionally provided with heat sink 7 in the one side the week side of boss of infrared light board 3.
The present invention sets thermal insulation board by the way that translucent cover housing and transparent cover plate are tightly connected between camera lens and fuselage,
So that thermal camera, which is realized, ensures that image quality is high while work long hours, while sealing is strong, it is to avoid infrared photography
Infrared light board in machine camera lens is by ectocine, and water resistance is high, and compared with existing thermal camera camera lens, of the invention is red
Outer camera lens have production cost low, simple in construction, eliminate interference of the fuselage to camera lens, substantially increase infrared
Video camera imaging quality;By further setting, i.e., heat sink is provided with the one side the week side of boss of infrared light board in thermal insulation board,
So that the heat Quick diffusing on infrared light board, further increases the heated interference of infrared detector on infrared light board, significantly
The performance of thermal camera is improved, can wide popularization and application.
Although specifically showing and describing the present invention with reference to preferred embodiment, appended claims institute is not being departed from
In the scope of the invention of restriction, the present invention can be made a variety of changes in the form and details, be the guarantor of the present invention
Protect scope.
