Description

Technical Field

[0001] The utility model relates to the technical field of photographic devices, in particular to a pan-tilt camera device. Background Art

[0002] A pan-tilt camera device generally includes a rotating base, a lens barrel and a lens, and the lens needs to be fixed inside the lens barrel. For a lens with heavy load and large volume, when fixing the lens to the lens barrel, an L-shaped adapter is usually used for connection. The long side of the L-shaped adapter is fixed to the side of the lens, and the short side of the L-shaped adapter is fixed to the inner side wall of the lens barrel, so as to realize the connection and fixation between the lens and the lens barrel.

[0003] When fixing the side of the lens with an L-shaped adapter, due to the large load of the lens, one end of the lens is embedded in the lens barrel, and the other end is fixedly connected to the lens barrel through the L-shaped adapter, so as to avoid the problem of eccentricity when the lens is connected to the lens barrel due to the excessive weight of the lens.

[0004] The setting of the L-shaped adapter makes the lens can only be fixed in the lens barrel, and the lens cannot rotate around its own axis. Moreover, this connection method has high requirements for the processing accuracy of the L-shaped adapter and the operation process of locking screws. The included angle between the two sides of the L-shaped adapter must be 90°, and the processing and installation are difficult. Since one end of the lens is embedded in the lens barrel and the other end is fixed to the lens barrel through the L-shaped adapter, it is easy to cause internal stress in the lens, resulting in the risk of lens out-of-step and affecting the imaging quality of the lens.
