Description

TECHNICAL AREA

The present application relates to a structure for locking a lens, and more particularly relates to a lens twist lock device.

BACKGROUND OF THE INVENTION

Currently, when a person needs to install a camera lens twist lock, the existing technology is to lock the camera lens to the adapter / camera using a card mounting seat. When a camera lens is mounted with a card mounting seat, there may be some gap between the lens and the adapter / camera after a long period of use due to friction between the contact surface of the lens and the adapter, causing the structure to mount and lock the lens on the card mounting seat becomes thinner, which prevents the lens from focusing and cannot provide a clear image for the camera sensor, requiring its improvement.

SUMMARY OF THE INVENTION

The purpose of the present application is to solve the above technical problems and to propose a lens twist lock device.

To achieve the above-mentioned object, the technical solution of the present application is: a lens rotation locking device, which comprises a lens and an adapter, wherein a lens arrangement recess is arranged for arranging the lens on the adapter, wherein a plurality of vertical fork flanges with claws in the Lens arrangement recess for adjusting the position of the lens is mounted on the adapter, wherein a claw is located between a base body of the vertical fork flange and the underside of the lens arrangement recess.

In the above technical solution, there are four vertical fork flanges and the four vertical fork flanges are evenly spaced and the four vertical fork flanges are arranged in a circle as a whole.

In the above technical solution, the lens arrangement recess is also provided with a friction lock ring under the claw, an adapter holder for locking the adapter is connected to the center of the friction lock ring, and a lens positioning hole for arranging the lens is arranged in the center of the adapter holder.

In the above technical solution, the adapter holder is also provided with a plurality of lens positioning holes and screw mounting holes.

In the technical solution mentioned above, the top of the lens is also provided with a base plate which is mounted on the base body of the vertical fork flange.

The present application provides four vertical fork flanges in the lens assembly recess of the adapter / camera and restricts the lens through the vertical fork flange so that the lens can be better locked onto the adapter.

At the same time, when the adapter holder (camera / camera holder) is locked in the appropriate position in the lens arrangement recess by means of the friction lock ring, the bottom plate of the lens can be placed directly on the vertical flange and the proper distance between the lens and the adapter can be maintained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The technical problem to be solved by the present application is: The existing technology is locking the camera lens to the adapter / the camera by means of a card mounting seat, which after a long period of use due to friction between the contact surface of the lens and the adapter there may be some gap between the lens and the adapter / camera, which makes the structure for mounting and locking the lens to the card mounting seat thinner so that the lens cannot focus and cannot provide a clear image for the camera sensor. In view of the above technical problems, the technical concept of the present application is that the vertical fork flange is arranged in the lens arrangement recess and the lens is limited by the vertical fork flange, thereby realizing the locking of the lens.

In order to clarify the technical purpose, the technical principle and the technical effect of the present application so that a person skilled in the art can understand and implement the present application in practice, a more detailed description of the present application is given below together with the drawings and specific embodiments .

The present application provides a lens twist lock device that includes a lens 1 and an adapter 2nd includes. As in the 3rd is shown when the part 12 on the existing lens 1 to the adapter 2nd is grown due to the friction between the lens 1 and the adapter 2nd the part 12 on the lens 1 thinner, leaving a gap between the lens 1 and the adapter 2nd is present. This will be the gap between the lens 1 and the adapter 2nd enlarge, which means that the lens cannot focus and cannot provide a clear image for the camera sensor.

In view of the problem that the existing lens is easily loosened for a long time after mounting in the adapter and use, the present application provides a vertical fork flange for the present adapter 2nd ready to adjust the position of the lens on the adapter / camera through the vertical fork flange so that the influence of friction between the lens 1 and the adapter 2nd is reduced due to the contact surface, whereby the locking of the lens rotation is realized.

In particular, as it is in the 1 and 2nd the vertical fork flange is shown 5 of the present application at the entrance of the lens arrangement recess 3rd on the adapter 2nd and a plurality of vertical fork flanges 5 with claws 4th is in the lens arrangement recess 3rd to adjust the position of the lens 1 on the adapter 2nd assembled. At the same time is for better locking of the lens 1 as it is in the 2nd is shown the claw 4th between a basic body 13 of the vertical fork flange 5 and the bottom of the lens assembly recess 3rd (That is, the claw is at the bottom of the lens assembly recess 3rd arranged).

In practice there may be three to five (four is preferred) vertical fork flanges. All vertical fork flanges are ring-shaped as a whole, and adjacent two vertical fork flanges are evenly spaced. In this way, the new design of four vertical fork flanges enables the lens to store the adapter / camera directly or indirectly.

To lock the position of the lens is a friction lock ring 6 under the claw 5 also in the lens arrangement recess 3rd Installed. The middle part of the friction lock ring 6 is with an adapter holder 7 to lock the adapter 2nd connected, and the middle part of the adapter holder 7 is with a lens positioning hole 8th to arrange the lens. This allows the lens to pass through the friction lock ring 6 to be mounted on the adapter.

In practice, the adapter is 2nd to further restrict the lens with a plurality of lens positioning holes 9 and screw mounting holes 10th fitted.

The top of the lens is for better installation of the lens and adapter 1 also with a base plate 11 provided on the base body of the vertical fork flange 5 is mounted. The bottom plate 11 can be mounted on the vertical fork flange of the adapter / camera with the correct flange spacing.

It should be noted that improvements or changes can be made to those skilled in the art as described above, and all such improvements and changes are intended to fall within the scope of the claims attached to the present application.
