One end of adjusting screw rod is stretched out vertical plate and is fixed with irony block, irony block adsorb on permanent magnetic plate, adjusting screw rod it is another
End is fixed with rotation section.
It is evenly equipped with bolt apertures on the end face of the drive gear centered on the central axis of drive gear, at least two
Be spirally connected in bolt apertures limited location head, and spacing head is relative with the induction end of the proximity switch being fixed with the madial wall of drive case
Should.
The bolt apertures of the drive gear are 12.
The present invention prominent effect be:Compared with prior art, camera can be rotated by automatically, meanwhile, its
The maximum angle of the anglec of rotation can be adjusted as needed, prevent from rotating transition, and its camera easy installation and removal.

Specific embodiment:
Embodiment, is shown in as shown in Figures 1 to 4, a kind of rotary pick-up head mechanism, including base plate 10 and camera 1, described
The top surface of base plate 10 is fixed with drive case 11, is fixed with driving servomotor 12, drives on the upper outside wall of drive case 11
During the output shaft of dynamic servomotor 12 stretches into drive case 11 and drive gear 121 is fixed with, in drive case 11, is provided with transmission
Axle 13, power transmission shaft 13 are hinged on two madial walls of drive case 11, and travelling gear 131 is fixed with power transmission shaft 13, are driven
Gear 121 is meshed with travelling gear 131, and one end of power transmission shaft 13 is stretched out drive case 11 and is fixed with camera link
14, there is on the level board 141 of camera link 14 through hole 142, the base plate of camera 1 is pressed against on level board 141, is imaged
1 camera lens stretches out through hole 142, and the top of the vertical plate 143 of camera link 14 is fixed with cylinder connecting plate 144, cylinder
Pusher cylinder 145 is fixed with the top surface of connecting plate 144, the push rod of pusher cylinder 145 passes through cylinder connecting plate 144 straight down
And connection movable block 146 is fixed with, connect in the vertical groove 147 that 146 sleeve of movable block has on vertical plate 143, connection
One end of movable block 146 is fixed with compact heap 15, and the middle part of compact heap 15 has middle through-hole 151, the main body sleeve of camera 1
In middle through-hole 151, the bottom surface of compact heap 15 is corresponding with the base plate of camera 1.
Further, the bottom surface of the compact heap 15 is fixed with cyclic spring set 152, the bottom surface of cyclic spring set 152
With circular orientation groove 153, circular orientation groove 153 is corresponding with the base plate of camera 1.
Further, put forth effort on cylinder in one end that the push rod upper sleeve of the pusher cylinder 145 has spring 16, spring 16
Connecting plate 144, the other end of spring 16 put forth effort on connection movable block 146.
Further, the drive case 11 is fixed with permanent magnetic plate 148 against on the side of vertical plate 143, vertically
Adjusting screw rod 149 is bolted with plate 143, one end of adjusting screw rod 149 is stretched out vertical plate 143 and is fixed with irony block 17, irony
Block 17 adsorbs on permanent magnetic plate 148, and the other end of adjusting screw rod 149 is fixed with rotation section.
Further, it is uniform centered on the central axis of drive gear 121 on the end face of the drive gear 121
Have bolt apertures 122, be spirally connected at least two bolt apertures 122 limited location head 123, spacing 123 with the madial wall of drive case 11
On the induction end of proximity switch 111 that is fixed with it is corresponding.
Further, the bolt apertures 122 of the drive gear 121 are 12.
Operation principle:Promoted by the push rod of pusher cylinder 145, cyclic spring set 152 can be pressed against camera 1
On base plate, so as to camera 1 is fixed, and when dismantling, it is only necessary to which the push rod of pusher cylinder 145 is lifted, and which removes and installs
It is convenient.
Pass through, drive servomotor 12 to run, camera link 14 can be caused to rotate, so as to adjust camera 1
Irradiating angle, and drive the angle of the operation of servomotor 12 corresponding can be controlled with spacing 123 by proximity switch 111
System, when proximity switch 111 with arbitrary one spacing 123 near when, allow for driving servomotor 12 out of service and only
Can invert, so as to limit the anglec of rotation of camera link 14.
And the bolt apertures 122 of drive gear 121 are 12, illustrate between two neighboring bolt apertures 122 as 30 °, that is, rotate
Angle is 30 °.
Finally, embodiment of above is merely to illustrate the present invention, and not limitation of the present invention, relevant technical field
Those of ordinary skill, without departing from the spirit and scope of the present invention, can also make a variety of changes and modification, therefore
The technical scheme of all equivalents falls within scope of the invention, and the scope of patent protection of the present invention should be defined by the claims.
