Background
Currently, when one needs to mount a lens breech lock for a camera or video camera, the prior art is to use a bayonet mount to lock the camera or video camera lens onto the adapter/camera/video camera. When a lens of a camera or a video camera is mounted using a bayonet mount, there may be some clearance between the lens and the adapter/camera/video camera after a long period of use due to friction between the lens and the contact surface of the adapter, which will make the structure for mounting the lock lens on the bayonet mount thinner, thereby making the head lens out of focus and providing a clear image for the camera sensor, and thus there is a need for improvement.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the above-mentioned technical problem, a boring locking device behind camera lens is proposed.
In order to realize the purpose, the technical scheme of the utility model is that: a lens rear boring locking device comprises a lens and an adapter, wherein a plurality of vertical fork-shaped flanges which are used for adjusting the position of the lens on the adapter and are provided with clamping jaws are installed in a lens placing groove, and the clamping jaws are located between a chassis of the vertical fork-shaped flanges and the bottom of the lens placing groove.
In the technical scheme, the number of the vertical fork-shaped flanges is four, the four vertical fork-shaped flanges are uniformly arranged at intervals, and the four vertical fork-shaped flanges are integrally arranged in a ring shape.
In the technical scheme, a friction locking ring positioned below the clamping jaw is further installed in the lens placing groove, the middle of the friction locking ring is connected with an adapter support used for locking the adapter, and a first lens positioning hole used for placing a lens is formed in the middle of the adapter support.
In the above technical scheme, the adapter bracket is further provided with a plurality of second lens positioning holes and bolt mounting holes.
In the above technical solution, the top of the lens is further provided with a bottom plate resting on the chassis of the vertical fork-shaped flange.
The utility model discloses a through add four perpendicular forked flanges in the camera lens standing groove of adapter/camera to carry on spacingly through perpendicular forked flange to the camera lens, thereby can be with the better locking of camera lens on the adapter.
Meanwhile, when the adapter holder (camera/camcorder holder) is locked in place in the lens placement groove using the friction lock ring, the bottom plate on the lens can rest directly on the vertical flange and make the proper distance between the lens and the adapter.
Drawings
The invention will be further explained with reference to the drawings and examples, wherein:
fig. 1 is a schematic structural view of a lens rear boring locking device according to the present invention;
FIG. 2 is a schematic structural diagram of a lens at a matching connection with an adapter;
fig. 3 is a schematic structural diagram of the adapter.
Detailed Description
The utility model discloses the technical problem that will solve is: the prior art of mounting a lens breech lock of a camera or a video camera by means of a bayonet mount, which may have some play between the lens and the adapter/camera/video camera after a long period of use, will make the structure for mounting the locked lens on the bayonet mount thinner, thereby making the head lens not in focus and providing a clear image for the camera sensor. To the above technical problem, the utility model discloses a technical thought is: the utility model discloses a set up perpendicular Y-shaped flange in the camera lens standing groove, carry on spacingly through perpendicular Y-shaped flange to the camera lens, and then realize the locking to the camera lens.
In order to make the technical purpose, technical solution and technical effects of the present invention more clear so as to facilitate those skilled in the art to understand and implement the present invention, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The utility model provides a boring locking device behind camera lens, including camera lens 1 and adapter 2. As shown in fig. 3, after the part 12 of the conventional lens 1 is assembled to the adapter 2 and used for a long time (which may take several years), the part 12 of the lens 1 becomes thin due to friction between the contact surfaces between the lens 1 and the adapter 2, so that a gap exists between the lens 1 and the adapter 2, which may cause looseness between the lens 1 and the adapter 2, thereby preventing the lens from being focused and providing a sharp image for the camera sensor.
After assembling to the adapter and long-term use to current camera lens, the not hard up problem appears easily, the utility model discloses an add perpendicular forked flange on current adapter 2, come control camera lens position on adapter/camera machine through perpendicular forked flange to reduce the influence that brings between camera lens 1 and the adapter 2 because the friction between the contact surface, and then realize the locking to lens breech lock.
Specifically, as shown in fig. 1 and fig. 2, perpendicular forked flange 5 be located the entrance of lens standing groove 3 on adapter 2, perpendicular forked flange 5 is for having the flange of jack catch and can arrange a plurality ofly, installs a plurality ofly in the lens standing groove 3 and is used for adjusting the position of lens 1 on adapter 2. Meanwhile, for better locking of the lens 1, as shown in fig. 2, the claws 4 are located between the bottom plate 13 of the vertical fork flange 5 and the bottom of the lens placement groove 3 (i.e., the claws are arranged facing the bottom of the lens placement groove 3).
In practice, the number of the vertical forked flanges can be three to five (preferably four), all the vertical forked flanges are arranged in a ring shape on the whole, and the two adjacent vertical forked flanges are arranged at equal intervals. Thus, the new design using four vertical forked flanges allows the lens to rest directly or indirectly on the adapter/camera/camcorder.
In order to lock the position of a lens, a friction locking ring 6 positioned below the clamping jaw 4 is further installed in the lens placing groove 3, an adapter support 7 used for locking the adapter 2 is connected to the middle of the friction locking ring 6, and a first lens positioning hole 8 used for placing the lens is formed in the middle of the adapter support 7. In this way the lens can rest on the adapter by means of the friction locking ring 6.
In actual operation, in order to further limit the lens, the bracket of the adapter 2 is further provided with a plurality of second lens positioning holes 9 and bolt mounting holes 10.
In order to enable a better mounting of the lens and the adapter, the top of the lens 1 is also provided with a base plate 11 resting on the chassis of the vertical fork flange 5, the base plate 11 resting on the vertical fork flange of the adapter/camera/camcorder with the correct flange distance.
It will be understood that modifications and variations can be made by persons skilled in the art in light of the above teachings and all such modifications and variations are considered to be within the scope of the invention as defined by the following claims.
