In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

As shown in fig. 1 to 3, the focusing

assemblies

100 and 100a according to the embodiments of the present invention are mainly used for focusing a spherical image pickup device 200 (see fig. 4) before it leaves a factory.

As shown in fig. 1-2, a focusing assembly 100 according to an embodiment of the present invention includes: the focusing rotary disc 1 is provided with a first end 11 and a second end 12 which are opposite along the axial direction, and comprises a light transmission hole 13 which penetrates through the first end 11 and the second end 12, and the light transmission hole 13 is used for light passing during focusing. The focusing assembly 100 further comprises a ball cover 2 arranged at the first end 11 of the focusing turntable 1 and an adapter sleeve 3 arranged at the second end 12 of the focusing turntable 1. The adapter sleeve 3 is used for being matched and sleeved with the lens 4 of the camera device 200. When the camera device 200 is focused, the rotating focusing dial 1 can drive the adapter sleeve 3 to rotate, and then drive the lens 4 of the camera device 200 to rotate so as to realize focusing on the camera device 200. The focusing turntable 1 of the present embodiment uses a flange.

The utility model discloses focusing subassembly 100 is connected with ball cover 2 and camera device 200's camera lens 4 respectively through setting up focusing carousel 1, rotates focusing carousel 1 and can realize that ball cover 2 and camera lens 4 focus together for focusing easy operation, efficiency improves, and the focusing precision improves, and the focusing error rate reduces.

The embodiment of the utility model provides an in focusing carousel 1 and ball cover 2 demountable installation. Illustratively, as shown in fig. 2, the focus dial 1 includes a ring groove 110 recessed inward from an end surface of the first end 11. The ball cover 2 is made of a transparent material, and includes a cover body 20 and a ring edge 21 extending from the periphery of the cover body 20 toward the end face of the first end 11. The annular edge 21 is matched and sleeved with the annular groove 110, so that the focusing turntable 1 and the spherical cover 2 can be detachably mounted.

In other embodiments, the focusing dial 1 and the ball cover 2 may also be detachably mounted by means of a snap connection, a screw lock, and the like, which is not limited herein.

Because the model of the lens 4 of the camera device 200 is different, the spherical cover 2 which is matched for focusing needs to be correspondingly matched, and the focusing turntable 1 and the spherical cover 2 are detachably mounted, so that the spherical cover 2 can be conveniently replaced, and the cost increase caused by integrally replacing the focusing assembly 100 is avoided.

As shown in fig. 2, the focusing dial 1 further includes a sleeve 14 extending from an end face of the second end 12 in a direction away from the end face. One end of the adapter sleeve 3 is in fit and sleeve joint with the sleeve 14, and the other end is in fit and sleeve joint with the lens 4 of the camera device 200.

Similarly, since the lens 4 of the image capturing apparatus 200 has different models, the adapter sleeve 3 also needs to be matched with different lenses 4, so that the adapter sleeve 3 and the sleeve 14 are set to be in sleeve joint, thereby facilitating the replacement of the adapter sleeve 3 without replacing the focusing assembly 100 as a whole, and saving the cost.

As shown in fig. 2, the adapter sleeve 3 is connected with the sleeve 14 in an interference fit manner, so that the adapter sleeve 3 is tightly fitted with the sleeve 14, and when focusing is performed, the sleeve 14 can drive the adapter sleeve 3 to rotate.

In this embodiment, the adapter sleeve 3 is connected to the lens 4 of the image pickup apparatus 200 in an interference fit manner. Because the shape of camera lens 4 is the cylindricality, selects interference fit can increase frictional force, realizes driving camera lens 4 and rotates.

As shown in fig. 2, the adapter sleeve 3 in this embodiment is made of a flexible material, which may be rubber or other flexible materials. Because the lens 4 is made of plastic materials, the surface of the lens is damaged by rigid interference fit, and therefore the adapter sleeve 3 is made of flexible materials. The inner surface of the adapter sleeve 3 is circumferentially provided with the sawtooth-shaped protrusions 301, the sawtooth-shaped protrusions 301 can increase friction force, meanwhile, the installation is convenient, and the phenomenon that interference is too large and the adapter sleeve is difficult to install in place is avoided.

As shown in fig. 2, saw-toothed protrusions 111 are arranged on the outer side surface of the focusing rotary table 1 along the circumferential direction, and are used for increasing the friction force with the hand of the operator and reducing the slippage.

As shown in fig. 3, the focusing assembly 100a of another embodiment of the present invention is different from the focusing assembly 100 in that the connection manner of the adapter sleeve 3a and the sleeve 14a is different, and the rest of the components can refer to the focusing assembly 100 and are not described herein.

One of the adapter sleeve 3a and the sleeve 14a is provided with a plurality of limiting parts 30a protruding outwards from the peripheral side thereof, and the other is provided with a plurality of open grooves 140a along the circumferential direction. The plurality of limiting parts 30a are arranged corresponding to the plurality of opening grooves 140a, and the plurality of limiting parts 30a and the plurality of opening grooves 140a are matched with a ferrule. When focusing is carried out, the sleeve 14a is driven by the focusing turntable 1a to rotate, the limiting part 30a interferes with the open slot 140a, and the adapter sleeve 3 is driven to rotate.

The connection mode of adapter sleeve 3a and sleeve 14a in this embodiment is simple in structure, and the cooperation is rotated reliably.
