Preferably, the mounting mechanism comprises a mounting block fixedly connected to the side wall of the first half ring, the upper end face of the mounting block is provided with a limiting groove, the side wall of the second half ring is provided with a connecting groove, and the upper end face of the second half ring penetrates through a threaded rod in threaded connection with the threaded rod.
Preferably, the mounting block and the connecting groove are matched with each other, and the mounting block extends into the connecting groove and is connected with the connecting groove in a sliding mode.
Preferably, the threaded rod is located right above the connecting groove, the lower end portion of the threaded rod is matched with the limiting groove, and the threaded rod extends into the limiting groove.
Preferably, the joints of the inner teeth of the inner walls of the first half ring and the second half ring are matched with each other, and the control groove is a cube with a side length of two centimeters.
Compared with the prior art, the utility model, its beneficial effect does:
1. through the effect of installation mechanism, can carry on spacingly to the installation piece, and then can carry on spacingly, simple to operate is swift to the second semi-ring.
2. Through the effect of control groove, in the finger lock income control groove, rotate the control groove afterwards, so can adjust the focus of camera lens.
In conclusion, the mounting block can be limited, the second half ring can be limited, and the mounting is convenient and rapid; the focal length of the lens can also be adjusted.
Drawings
Fig. 1 is a schematic structural diagram of an additional ring gear of an optical lens according to the present invention;
fig. 2 is an enlarged view of a point a in fig. 1.
In the figure: 1 first semi-ring, 2 second semi-ring, 3 control tank, 4 internal teeth, 5 installation pieces, 6 spread grooves, 7 spacing grooves, 8 threaded rods.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-2, an additional ring gear for an optical lens includes a first half ring 1 and a second half ring 2, inner side walls of the first half ring 1 and the second half ring 2 are fixedly connected with inner teeth 4, two mounting mechanisms are disposed between the first half ring 1 and the second half ring 2, each mounting mechanism includes a mounting block 5 fixedly connected to a side wall of the first half ring 1, an upper end surface of each mounting block 5 is provided with a limiting groove 7, a side wall of the second half ring 2 is provided with a connecting groove 6, the mounting blocks 5 are matched with the connecting grooves 6, the mounting blocks 5 extend into the connecting grooves 6 and are slidably connected with the connecting grooves, a threaded rod 8 in threaded connection with the second half ring 2 penetrates through the upper end surface of the second half ring 2, the threaded rod 8 is located right above the connecting groove 6, a lower end portion of the threaded rod 8 is matched with the limiting groove 7, the threaded rod 8 extends into the limiting groove 7, when the additional ring gear needs to be mounted, the first half ring 1 is attached to an outer side wall of the lens, then the mounting blocks 5 on the second half ring 2 are inserted into the connecting grooves 6, and finally the threaded rod 8 extends into the limiting groove 7, so that the second half ring can be conveniently mounted, and the limiting groove 2 can be mounted.
The lateral wall of first semi-ring 1 and second semi-ring 2 all is equipped with a plurality of control grooves 3, and the junction of the interior internal tooth 4 of first semi-ring 1 and 2 inner walls of second semi-ring matches each other, and control groove 3 is the square that the length of a side is two centimetres, and when needs were adjusted the focus of camera lens, the finger was detained in control groove 3, rotates control groove 3 afterwards, so can adjust the focus of camera lens.
