A kind of cradle head device
Technical field
The utility model belongs to camera support technical field, and in particular to a kind of cradle head device.
Background technology
Cradle head device is used to support the capture apparatus such as camera, video camera, and the capture apparatus can typically pass through the cloud
Platform adjusts shooting angle, however, existing cradle head device is the head is adjusted the rotation of capture apparatus, the angle of pitch
Degree, typically using complex motion, causes the manufacture difficulty of cradle head device processed to increase, high expensive, in addition, existing
The most delicate structure of head, it is not appropriate for capture apparatus of the support with larger quality.
Cradle head device on the market at present, overall structure being made using plastics cast parts mostly, its advantage is that material is lighter, into
Type effect is good, but the plastic gear in working of plastics is easy to wear, and after top-loaded camera, gear easily skids, and service life is short.For
Solve the above problems, have business research, made using ironware, irony cradle head device overall structure is more thick and heavy solid, prolonged
It is durable, but in this irony cradle head device design structure, unstable by motor driving angle, camera swings to certain angle
Degree, makes instant jitter after centre-of gravity shift, and sound abnormal sound is produced in Medical Treatment Room, and image rocks.
Patent document CN103883854 discloses a kind of cradle head device, as shown in figure 1, it includes a cover body, a tune
One integral piece, a support member and a locking member.The cover body offers one first adjustment opening.The adjustment part includes one
Individual spherical adjustment portion and a connecting portion being fixedly linked with the adjustment portion, the adjustment portion are contained in the cover body,
The white first adjustment opening of the connecting portion it is secondary go out the cover body outside.The adjustment part is by the adjustment portion relative to described
The rotation of cover body adjusts position and angle of the connecting portion relative to the cover body.The support member is used to support the adjustment
Portion.The locking member, which is used to the adjustment part locking onto the support member and the cover body, to be asked or releases to the tune
The locking of one integral piece.
But there are the following problems for cradle head device disclosed in patent document CN103883854:
