Abstract

The utility model relates to a concealed camera head apparatus for television monitoring, which is an improvement of the existing devices. In the apparatus, a horizontal direction rotational motor is installed outside a main frame, which enables the tail section of a camera to have enough space without any limitation when the tail section rises up to move vertically at the angle of 90 deg. The apparatus also changes the driving mode of a drive mechanism to lead a driving wheel to rotate along the outer margin of a circular disk, which therefore, reduces the radial dimension of the circular disk and the weight of the apparatus, and brings convenience to installation and maintenance.

Description

The hemisphere suspended head

The utility model relates to a kind of camera head device that is used for TV monitoring and controlling.

At present, the camera head device that is used for the TV monitoring and controlling aspect, the device that can support and make vidicon camera to rotate in the desired direction, great majority are open types, device proper and alignment lens target clearly if it is arranged on the public place, cause the attention or the dislike of subject easily, what replace will be recessive type, decoration, be difficult for being videotaped cradle head device by what target subject aroused attention.Be recessive type as a kind of camera head device of external production, but the drive motor of its substantially horizontal rotation directly is placed in the main frame of The Cloud Terrace, occupy the suitable space of main frame, limited location system when making vidicon camera do vertical motion, and the driving wheel of its driving mechanism is the inner ring rotation at disk, thereby the size of disk is bigger, and weight increases, and is not easy to install, safeguard.

The purpose of this utility model is that the existing structure that is used for the camera head device of TV monitoring and controlling is improved, make vidicon camera in the TV monitoring and controlling process of recessive type, can not only rotate in the horizontal direction flexibly, easily with The Cloud Terrace, and when movement in vertical direction, its position is not subjected to any restriction, simultaneously, change the kind of drive of driving mechanism, make the structure of device simpler, weight is lighter, installs, safeguards more convenient.

The purpose of this utility model is to realize like this, a kind of hemisphere suspended head, by motor, driving mechanism, main frame, carriage, outer cover, ball cover, controlling mechanism, circuit board constitutes, carriage is a thin-walled U-shaped shape, sidewall upper at carriage has a hole, main frame is a thin-walled U-shaped shape, main frame is supporting carriage, driving mechanism comprises driving wheel, follower and disk, driving wheel and follower are a kind of pulley, disk is clamped between driving wheel and the follower, and rotates with driving wheel and follower, and disk and main frame are tightened to one, the axle of follower is fixed on the outer cover, motor comprises the motor A of substantially horizontal rotation and the motor B that Vertical direction is rotated, and motor A is fixed on the outer cover, the output shaft of motor A and the driving wheel close-fitting in the driving mechanism, motor B is fixed on the outside of main frame, the hole close-fitting of the output shaft of motor B and carriage sidewall upper, ball cover are the hemisphere of single sided perspective, are located by pulley.

The utility model is owing to improve the structure of camera head device; the motor that substantially horizontal is rotated is installed on the outer outer cover of main frame; thereby make the space of main frame bigger; the afterbody of vidicon camera is done vertical 90 ° of whens motion erecting; the space is unimpeded; be not subjected to any restriction; owing to changed the kind of drive of driving mechanism, driving wheel is rotated along the outer rim of disk, thereby reduced the radial dimension of disk again; dwindled the volume of device; alleviated weight, be easy to install; safeguard, and this device places in the safety cover of hemisphere type; hidden monitoring can be carried out, infecting of dust can be prevented again.

Below in conjunction with accompanying drawing structure of the present utility model is specifically described:

Remove A behind outer cover and the ball cover among Fig. 2 Fig. 1 to partial view

The utility model such as Fig. 1, shown in Figure 2, camera head device in the horizontal direction with the rotation angle of Vertical direction, rotational velocity is respectively by motor A1 and motor B14 control, motor A1 is an ac synchronous motor, be fixed on the outer cover 7, driving wheel 2 close-fittings in its output shaft and the driving mechanism, driving mechanism is then by 1

driving wheel

2,2

followers

5 and 1 disk 3 constitute, fluted in the wheel body of driving wheel 2 and follower 5, the width of this groove is consistent with the thickness of disk 3, disk 3 is clamped between driving wheel 2 and the follower 5, when driving wheel 2 rotates, driving disk 3 and follower 5 rotates together, the spring loose pin 13 that can regulate disk 3 clamping forces is arranged in the outside of motor A1, and it is to realize by the axial spacing of regulating driving wheel 2 and follower 5.Main frame 6 is a thin-walled U-shaped shape structure, with 4 screw posts the disk 3 in main frame 6 and the driving mechanism is tightened to one at an upper portion thereof, carriage 10 is a thin-walled U-shaped shape structure, flexibly connects with main frame 6, by main frame 6 supporting brackets 10, vidicon camera 15 is fixed on the bottom of carriage 10.When the forward and reverse rotation of motor A1, main frame 6 and carriage 10 drive vidicon camera 15 simultaneously and do the substantially horizontal rotation along with disk 3 rotates together, and rotational velocity is 5 rev/mins, and rotation angle is 0 °-360 °.Motor B14 is an ac synchronous motor, be fixed on the outside of main frame 6, corresponding hole close-fitting on its output shaft and the carriage 10, when the forward and reverse rotation of motor B14, carriage 10 rotates with the output shaft of motor B14, main frame 6 is motionless, and 15 in vidicon camera is done upwards 0 °-90 ° or downward 0 ° of-90 ° of motion in Vertical direction, and its rotational velocity is 5 rev/mins.

Camera head device is enclosed in the ball cover 9, and ball cover 9 is a kind of single sided perspective, hemispheric, is positioned on dull and stereotyped 11 by 4 pulleys 8.For ease of installing, safeguarding, side's cover 12 of a worn-out open form is housed on outer cover 7, motor A1, spring loose pin 13 and plug-in type circuit board 4 are lived by square cover cap.
