Description

Technical Field

[0001] This utility model relates to camera accessories, and in particular to a camera lens adapter. Background Technology

[0002] Currently, most cameras on the market use a spiral connection method to assemble various camera lens accessories. However, constantly disassembling and assembling the accessories can easily cause wear and even damage to the spiral structure of the camera. This not only affects the installation effect of various accessories during use, but also affects the shooting effect due to unstable accessory installation, and also greatly increases the cost of photography. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a camera lens adapter that facilitates the assembly of other camera accessories with the camera, better protects the camera from wear and damage, and extends the camera's lifespan.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows: a camera lens adapter, comprising a lens body, a connecting frame, a lens cover, and an adapter ring. The connecting frame assembles the lens cover and the adapter ring into one unit. The adapter ring has a first connecting ring and a second connecting ring at its two ends respectively. The outer wall of the first connecting ring is provided with a first external thread. The inner ring of the camera aperture of the lens body is provided with a first internal thread that matches the first external thread. The first connecting ring is rotatably connected to the lens body. The outer wall of the second connecting ring is provided with snap-fit ​​blocks. The inner end of the connecting frame is provided with limit blocks. A groove is formed between each limit block. The snap-fit ​​blocks pass through the groove and rotate into the inner end of the limit blocks. The inner wall of the second connecting ring is provided with a second internal thread that is the same as the first internal thread.

[0005] Furthermore, magnetic material is provided around the outer end face of the connecting frame and around the mirror cover.

[0006] Furthermore, the side wall of the connecting frame is provided with an assembly groove, and an elastic body is installed in the assembly groove. The inner end face of the elastic body forms an elastic space with the inner wall of the connecting frame.

[0007] Furthermore, the outer wall of the adapter ring is provided with anti-slip texture.

[0008] Compared with existing technologies, it has the following beneficial effects:

[0009] This utility model adopts an adapter ring design, which can greatly reduce the number of times the lens thread is assembled, slow down lens wear, effectively avoid lens damage and increase shooting costs. The adapter ring can also facilitate the assembly of other compatible camera accessories, making both photography and videography very convenient. During installation, simply screw the adapter ring onto the lens and then snap the connecting frame onto the adapter ring. When other accessories are needed, simply screw them directly onto the second internal thread. When not in use, the lens cover can be magnetically attached to the connecting frame, which can effectively protect the camera. Attached Figure Description

[0011] Figure 2 This is a schematic diagram of the lens body structure of this utility model.

[0012] Figure 3 This is a schematic diagram of the adapter ring structure of this utility model.

[0013] The present invention will now be described in further detail with reference to the accompanying drawings. Detailed Implementation

[0014] like Figures 1 to 3 As shown, a camera lens adapter includes a lens body 1, a connecting frame 2, a lens cover 21, and an adapter ring 3. The connecting frame 2 assembles the lens cover 21 and the connecting ring 3 into one unit. Magnetic material 4 is provided around the outer end face of the connecting frame 2 and around the lens cover 21, which can facilitate the disassembly of each component and make it easy to replace accessories with different parameters for different photography needs, thus better ensuring the photography effect. The outer wall of the adapter ring 3 is provided with anti-slip texture 31 to better ensure stability.

[0015] The adapter ring 3 has a first connecting ring 32 and a second connecting ring 33 at both ends. The outer wall of the first connecting ring 32 has a first external thread 34, and the inner ring of the camera port of the lens body 1 has a first internal thread 11 that matches the first external thread 34. The first connecting ring 32 is screwed to the lens body 1. The outer wall of the second connecting ring 33 has snap-fit ​​blocks 35. The inner end of the connecting frame 2 has a limiting block 22. A groove 23 is formed between each limiting block 22. The snap-fit ​​block 35 passes through the groove 23 and rotates into the inner end of the limiting block 22. The inner wall of the second connecting ring 33 has... The lens body 1 has a second internal thread 36 that is identical to the first internal thread 11. The adapter ring 3 can greatly reduce the number of times the lens body 1 is threaded, reduce lens wear, and effectively avoid lens damage that would increase shooting costs. The adapter ring 3 can also be used to easily assemble other compatible camera accessories, making both photography and videography very convenient. During installation, simply screw the adapter ring 3 onto the lens body 1 and then snap the connecting frame 2 onto the adapter ring 3. When other accessories are needed, simply screw them directly onto the second internal thread 36. When not in use, the lens cover 21 can be attached to the connecting frame 2 to protect the camera.

[0016] The side wall of the connecting frame 2 is provided with an assembly groove 24, and an elastic body 25 is installed in the assembly groove 24. The inner end face of the elastic body 25 forms an elastic space 26 with the inner wall of the connecting frame 2. After the connecting frame 2 and the adapter ring 3 are fastened together, the elastic force of the elastic body 25 can greatly increase the firmness between the two. The assembly is very stable without human intervention.

[0017] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
