Abstract

The utility model relates to a lamp and lantern type industrial disappearing television camera, comprising a camera, a driving device, a spherical casing and a hanger. The utility model is characterized in that the lens and the circuit of the camera is fixedly installed in the spherical casing, the lens is positioned in the middle position, a pitching rotating mechanism and a camera electric appliance are installed on the surrounding of the lens, a horizontal rotating mechanism is installed in the hanger, and a spherical single-face combining glass cover is installed outside the spherical casing and the arc frame. The utility model has the advantages that the view angle of the camera is enlarged, simultaneously the camera is uneasy to be recognized by people, additionally the single-face combining glass protective cover is installed outside, so the working condition of the camera has greater invisibility.

Description

Lamps and lanterns type industrial disappearing television camera

The utility model relates to the stealthy industrial television camera of a kind of light fixture formula, is fit to be applied to industries such as industry, commerce, public security and carries out the shooting of hidden TV monitoring and controlling.

Common industrial television surveillance system device is that video camera is fixedly mounted on the electric platform, this device volume is big, heavy, and target is open, do not possess disguise, therefore the applicant once proposed the patent application of the spherical industrial television surveillance system device of an implicit expression, and obtained utility model patent, its patent No. is 92210904.4, this device has adopted spherical stealthy camera housing, but be installed in the top of spherical because of transmission device and electrical apparatus control system, make the actual hemisphere that becomes of spherical housing, be restricted with regard to the visual angle that makes video camera like this, though video camera is equipped with the hemisphere protective cover outward, be the transparent body, therefore lose its disguise.

The purpose of this utility model provides a kind of novel stealthy industrial television camera, and it can make the visual angle of video camera openr, and disguised better.

The purpose of this utility model is achieved in that it comprises video camera, transmission mechanism, spherical housing and suspension bracket, it is characterized in that camera lens and camera circuitry are fixedly mounted in the spherical housing, the camera lens position that mediates, pitching rotating mechanism and camera circuitry are installed around it, horizontal rotary mechanism is housed in the suspension bracket, suspension bracket is hinged by an arc support and spherical housing both sides, and a spherical single sided perspective glass shield is installed outside spherical housing and arc support.

Profile of the present utility model is spherical pendant type, can enlarge on the one hand the visual angle of video camera, is simultaneously more difficultly discerned by the people, in addition because the single sided perspective glass shield has been installed in the outside, so the working condition of video camera just has its disguise more.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the structure cutaway view of a kind of specific embodiment of the present utility model.

Fig. 2 is the structural representation that horizontally rotates.

1 is camera lens among the figure, the outside is covered with spherical housing 2, in the middle of camera lens is positioned at, pitching rotating mechanism and camera circuitry 3 are housed on every side, horizontal rotary mechanism 5 is housed in the suspension bracket 4, the hanging axis 5 of horizontal rotary mechanism is hinged with the spherical housing both sides by the arc support 6 that is fixedly connected with it, and 7 is single sided perspective glass shields among the figure.

In the pitching rotating mechanism, motor and decelerator are fixed on the interior support 10 of spherical housing, driving pinion 13 by motor 8 by decelerator 9 rolls around gear wheel 20, and be installed with a limit switch 11 on the gear wheel 20, on the spherical housing inwall, be fixed with two guide vane end stops 12, when pinion 13 and spherical housing went to certain angle, guide vane end stop bump limit switch made the transmission mechanism commutation.

Horizontal rotary mechanism is to drive 17 rotations of worm screw 16 worm gears by motor 14 by a pair of gear 15, with the coaxial shift fork 18 that is equipped with of worm gear, and limit switch 19 is housed at the suspension bracket internal fixation, when shift fork goes to limit switch, promptly clash into limit switch, the transmission mechanism commutation, the quantity of shift fork setting and setting angle are decided on the operating angle of video camera.

Claims

1, the stealthy industrial television camera of a kind of light fixture formula, it comprises video camera, transmission mechanism, spherical housing and suspension bracket, it is characterized in that camera lens and camera circuitry are fixedly mounted in the spherical housing, the camera lens position that mediates, pitching rotating mechanism and video camera electrical equipment are installed around it, horizontal rotary mechanism is housed in the suspension bracket, and suspension bracket is hinged by an arc support and spherical housing both sides, and a spherical single sided perspective glass shield is installed outside spherical housing and arc support.
