Abstract
The utility model discloses an improved infrared vidicon. The main improvement lies in that the transparent hood (13) of the vidicon is a spherical annular design at the externally revealed surface after being assembled with a casing (12). With the design of the spherical annular transparent hood adopted, the vidicon can obtain a bigger infrared light transmission area under the same infrared light mounting caliber size; the quantity of infrared LED lights are allowed to be increased to improve the irradiation distance and the infrared LED lights are allowed to be mounted by high and low levels, thus being beneficial to the adjustment of the angle of transmitting beams. Besides, a rotary connecting rod mechanism (15) which is convenient for externally adjusting the focus of a lens is arranged in the lens (11), thus leading that the focusing and the zooming of the lens can be directly adjusted from an adjusting hole of the outer casing by a common screwdriver without the open of the outer casing; furthermore, the manufacturing technique of the external adjusting mechanism is comparatively simple and the manufacturing cost is reduced.
Description
Technical field
The utility model relates to the field of monitoring camera-shooting technology, specifically is a kind of improved thermal camera.
Background technology
On the at present domestic and international security protection video monitoring market, state-of-the-art active infrared day and night type video camera has all adopted plane dicyclo translucent cover structure, interior ring circular glass sheet is used for the camera lens photosensitive imaging, outer shroud translucent cover (glass or various infrared transparent plastic materials) is used for the transmission of night vision infrared light supply, inlay infrared stray light between the inner and outer ring and intercept circle (aluminium circle), influence the CCD image quality by camera lens to avoid infrared stray light; And because the restriction of planar transparent cover, installable LED lamp quantity is less in the video camera, makes irradiation distance limited.In this type of thermal camera,, very inconvenient if equipped manual zoom lens because structural characteristics during project installation and commissioning, must be opened shell, could be adjusted lens focus and zoom.
The utility model content
The utility model desires to remedy the defective of prior art, and a kind of improved thermal camera that adopts the sphere translucent cover to replace the conventional planar translucent cover is provided.
To achieve these goals, improved thermal camera of the present utility model is made up of camera and base, and camera is assemblied on the base; Camera comprises camera lens, shell, translucent cover and infrared LED lamp plate; Translucent cover is located at the top of shell, lens assembly in the enclosure, the infrared LED lamp plate is located on around the camera lens, translucent cover with shell assembling after exposed face be the sphere annular.
After translucent cover adopts the sphere annular design, make and install under the caliber size at identical infrared lamp, sphere shape translucent cover can obtain bigger infrared transmission area than traditional planar shaped translucent cover, can allow to increase infrared LED lamp quantity, improve irradiation distance, and allow the infrared LED lamp to divide high and low layered installation, be beneficial to and adjust the emission beam angle.
As improvement of the technical scheme, be provided with two circle infrared LED lamps on the infrared LED lamp plate at least, the height of infrared LED lamp is reduced to the outer ring from coil to coil by inner ring, and each encloses the gradient of infrared LED lamp formation and the curvature coupling of sphere translucent cover.
As improvement of the technical scheme, also be provided with the rotating linkage mechanism of forming by swingle, connecting rod, rotation plate rail, small rack in the camera lens; Small rack is fixed on outer casing inner wall, rotates plate rail and is fixed on the camera lens; Swingle is located on the small rack, and an end is assemblied in and has on the shell in the adjustment hole, and it is hinged with the rotation plate rail by connecting rod that the other end passes small rack; See through adjustment hole twisting swingle and can regulate lens focus, zoom.After adopting this structure, when making project installation and commissioning, do not need to open shell, can directly adjust lens focus and zoom with the normal screws cutter from the shell adjustment hole, and the manufacturing process of this outer regulating mechanism is simple relatively, production cost reduces.

Embodiment
Shown in Fig. 1,2,3,4,5,6:
A kind of improved thermal camera comprises camera 1 and base 2, and camera 1 is assemblied on the base 2, and camera 1 comprises camera lens 11, shell 12, translucent cover 13 and infrared LED lamp plate 14; Translucent cover 13 is located at the top of shell 12, and camera lens 11 devices are in shell 12, and infrared LED lamp plate 14 is located on around the camera lens 11, and the exposed face of translucent cover 13 after assembling with shell 12 is the sphere annular.
At least be provided with two circle infrared LED lamps on the infrared LED lamp plate 14, the height of infrared LED lamp is reduced to the outer ring from coil to coil by inner ring, and each encloses the gradient of infrared LED lamp formation and the curvature coupling of translucent cover 13.
Have adjustment hole 121 on the shell 12, also be provided with rotating linkage mechanism 15, rotating linkage mechanism 15 comprises swingle 151, connecting rod 152, rotates plate rail 153, small rack 154; Small rack 154 is fixed on shell 12 inwalls, rotates plate rail 153 and is fixed on the camera lens 11; Swingle 151 is located on the small rack 154, and an end is assemblied in the adjustment hole 121 that has on the shell 12, and it is hinged with rotation plate rail 153 by connecting rod 152 that the other end passes small rack 154; See through adjustment hole 121 twisting swingles 151 and can regulate camera lens 11 focusing, zoom.
Certainly, the shell 12 of this thermal camera can also be other shape except sphere, as commercially available on the market long tubular at present, rectangular-shaped etc.Equally, base 2 also is like this.These conversion all fall within the protection range of the present utility model.
