Description

Infrared spherical pan head

Technical field

The utility model relates to the The Cloud Terrace that video camera is used in a kind of closed-circuit TV monitoring system, particularly a kind of infrared spherical pan head.

Technical background

At present the The Cloud Terrace of prior art is to rotate the control The Cloud Terrace by central shaft to change, want to solve night vision function must external one be set with infrared illuminator required with the synchronous operated gear train of The Cloud Terrace.Therefore have problems such as complex structure, practical cost height, installation and synchronous debugging difficulty, practicality is relatively poor for this reason.

Summary of the invention

In view of there is above problem in prior art, the utility model provides a kind of infrared spherical pan head promptly to be specially adapted to have the The Cloud Terrace of night vision function.The technical scheme that the utility model is taked is: a kind of infrared spherical pan head; It comprises horizontal electric motor units, motor vertical unit, shell, lens bracket, hemisphere translucent cover, it is characterized in that: also comprise rotating basis, infrared emission unit support, camera lens darkening ring, described rotating basis comprises two gear rings and pedestal; Described gear ring inboard is the teeth structure; Gear ring is provided with a circle indent step near the end face of teeth, and the gear ring outer ledge has the convexity of equidistance, and described pedestal is clipped in the groove of the corresponding snapping formation of two gear rings; Be screwed and make pedestal and gear ring clearance fit; Described infrared emission unit support is screwed in the lens bracket two sides, and lens bracket is fixed on the rotating basis lower end through bearing pin, and described camera lens darkening ring is bonded at hemisphere translucent cover the inside; The hemisphere translucent cover is linked up with buckle-type with the ball cover on being fixed on rotating basis and is connected.

Described camera lens darkening ring be arc square frame its arc length identical with the interior radian of hemisphere translucent cover greater than 90 °, its height, width do not inject with infrared ray and is as the criterion, the camera lens darkening ring scribbles the shading black paint.

The utlity model has following beneficial effect: the utility model has increased night vision function on common The Cloud Terrace, practical; Have characteristics such as simple in structure, that cost is low, Installation and Debugging are convenient simultaneously.

Embodiment

The principle of work of the utility model is: the rotation of central shaft location is changed into external diameter Positioning Gear rotating manner; Lens bracket and hemisphere translucent cover are fixedly connected do parallel and vertical running together synchronously; The darkening ring that is fixed in the transparent ball cover is cut apart the reflection of having blocked, prevented infrared beam to infrared beam, make the video camera operate as normal.

As shown in the figure, infrared spherical pan head comprises horizontal electric motor units 2, motor vertical unit 14, shell 1, lens bracket 7, hemisphere translucent cover 9, rotating basis, infrared emission unit support 6, camera lens darkening ring 8.

Rotating basis comprises gear ring 4 and pedestal 12.Pedestal 12 is injection molded into disc for the ABS material; It is lower wall 15, lower wall 16 that the lower surface is injected with two sidewalls, has two symmetrical concentric circular holes in two sidewall lower wall 15, lower wall 16 lower ends, on pedestal 12 upper surfaces, is injected with a U type support 17; In U type support 17 1 sides a upper side wall 18 is arranged; Have a circular hole in upper side wall 18 lower ends,, on lower wall 16 lower end pedestals 12 planes, be screwed horizontal limit switch 11 and spacing driving lever 13 through screw retention motor vertical unit 14; Rotate back and forth angle with the qualification level; At the vertical limit switch 3 of fixed outside of U type support 17 opposite side pedestals 12,, on its plane, be screwed horizontal electric motor units 2 to limit the vertical movement angle.

Gear ring 4 is processed for makrolon material; Its inboard is the teeth structure; Gear ring 4 is provided with a circle indent step near the end face of teeth, and gear ring 4 outer ledge equidistance have 6 convexities, pedestal 12 is clipped in two gear ring 4 correspondences snaps together in the groove of formation; Be screwed and make pedestal 12 and gear ring 4 clearance fit, then rotating basis is carried out buckle through gear ring 4 outer ledges are protruding with shell 1 concentric corresponding shrinkage pool.

Video camera is fixed on the lens bracket 7; Lens bracket 7 is a two side asymmetrical type U type structure; Have the concentric circle holes of two identical symmetries in the upper end, two sides; Be screwed two infrared emission unit supports 6 of installation in the lower end of two mother rib lateral rotundums, infrared illuminators be installed at two infrared emission unit supports 6.Be provided with in the outside of lens bracket 7 one sides and surpass 90 ° sector, the lower wall 15 of the two sides of lens bracket 7 and pedestal 12, lower wall 16 staggered being installed together are then blocked with split washer through the circular hole connection with bearing pin 10.

Camera lens darkening ring 8 is that arc square frame its arc length identical with the interior radian of hemisphere translucent cover 9 is greater than 90 °; Its height, width are not injected with infrared ray and are as the criterion; Camera lens darkening ring 8 scribbles the shading black paint; Be bonded at the inside in the hemisphere translucent cover 9, then hemisphere translucent cover 9 linked up with 5 buckle-types with 4 ball covers on being fixed on rotating basis and be connected.

The gear of motor

vertical unit

14 and 7 vertical movements of lens bracket 7 sector bite strap index glass head brackets, horizontal electric motor units 2 gears and gear ring 4 teeth interlocks are carried out 360 ° along contrary rotation with external diameter location rotating manner driven rotary pedestal.
