[0002] In today's society, more and more people enjoy photography and digital cameras. Many enthusiasts want to experience the shooting experience offered by lenses from different brands on their existing cameras. This requires a device that allows for the conversion between different brands of cameras and lenses—an adapter ring. Adapter rings can connect lenses from different brands to cameras, greatly expanding lens options and enabling better utilization of lenses from other mount series.

[0003] During the use of adapter rings, the lens release is typically controlled by a raised release button formed by a combination of a lever and a spring. In this conventional design, since the release button is raised above the mounting plane, when installing large-diameter lenses, especially those with a diameter larger than the button, the lens's outer diameter can easily press against the release button, affecting the reliability and accuracy of the lens installation. Moreover, this raised design requires sufficient installation space, and some adapter rings do not have enough installation space, thus requiring special designs to meet structural requirements.

Detailed Implementation

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0018] like Figure 1-4 As shown, an adapter ring with a ring-shaped lens release button includes an adapter ring body 1. One end of the adapter ring body 1 forms a camera mount 2, and the other end forms a mounting groove. A mounting platform 3 is provided in the mounting groove. A retaining groove 4 is formed between the mounting platform 3 and the side wall of the mounting groove. A ring-shaped lens release button 5 and a lens connector 6 are connected sequentially to the mounting groove. A release button 7 is formed by extending the outer plane of the ring-shaped lens release button 5. A lens locking post 8 is connected to the inner side of the corresponding position. One end of the lens locking post 8 passes through the lens connector 6 and can perform elastic telescopic movement. A limiting groove 9 is provided on the mounting platform 3. The lens locking post 8 is located in the limiting groove 9, and an elastic movement space is formed between the other end of the lens locking post 8 and the bottom of the limiting groove 9.

[0019] The adapter ring structure of this utility model is simple. By designing the lens release button as a ring structure, the release button 7 is in a flat position relative to the overall adapter ring, which greatly reduces the installation space of the lens release button and the overall size of the adapter ring, making the structure of the adapter ring more compact and easier to install. It can effectively avoid interference of the release button to the lens during installation, improve the installation efficiency and accuracy of the lens, and reduce the use cost of the adapter ring.

[0020] Furthermore, such as Figure 1-2 As shown, the ring lens release button component 5 includes a ring piece, a release button 7 is formed on the outer side of the ring piece, and a connecting piece 10 extends from the inner side of the corresponding position of the release button 7. A release button positioning groove 11 is provided on the adapter ring body 1. The ring piece is inserted into the slot 4 so that the release button 7 is located in the release button positioning groove 11, the connecting piece 10 is located in the limiting groove 9, and the lens locking post 8 is connected to the connecting piece 10 by screws.

[0021] In the above design, the ring-shaped lens release button 5 adopts a ring-shaped plate design, which is simple in structure and easy to install. It can be directly inserted into the slot 4. When in use, by utilizing the material of the ring plate itself and the elasticity of the ring design, pressing the release button 7 will move the ring-shaped lens release button 5 towards the mounting slot, thereby causing the top of the lens locking post 8 to retract into the lens connector 6, and the lens can be removed. Conversely, when installing the lens, by rotating the adapter ring, the lens locking post 8 is pressed into the lens connector 6. When the lens locking post 8 is close to the connection position on the lens, the lens locking post 8 will pop out of the lens connector 6 and lock into the connection position of the lens, completing the lens installation. The installation process is not affected by the release button 7, improving the efficiency and accuracy of lens installation and removal.

[0022] Furthermore, fixing screws are provided between the side of the annular plate and the lens connector 6, and fixing screws are also provided at intervals between the lens connector 6 and the mounting platform 3. This design strengthens the connection between the various components, thereby improving the stability of the adapter ring in use.

[0023] Furthermore, such as Figure 3-4 As shown, the ring-shaped lens release button 5 includes a ring seat. A ring of retaining platforms 12 is formed on one side of the ring seat, and a ring of protrusions 13 is formed on the other side. The retaining platforms 12 are engaged in the retaining grooves 4, so that the ring seat covers the mounting platform 3. The release button 7 is formed on the outer side of the protrusions 13, and the outer end of the release button 7 is flush with the outer wall of the ring seat. A retaining block 14 is formed on the inner side of the corresponding position of the release button 7 to hold the lens locking post 8. An elastic element is provided in the lens locking post 8, and the bottom end of the elastic element is in elastic contact with the bottom of the limiting groove 9. Protrusions 15 are provided at intervals on the ring seat, and grooves 16 are provided at intervals on the mounting platform 3 corresponding to the protrusions. An elastic element is provided in the groove 16, and the top end of the elastic element is in elastic contact with the protrusion 15.

[0024] The above-mentioned design, the ring seat structure, can strengthen the connection stability of the ring lens release button 5. At the same time, it is also to cooperate with the design of the elastic parts at each position to improve the ease and smoothness of operation of the release button 7, thereby improving the overall flexibility and stability of the adapter ring.

[0025] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
