Description

Technical Field

[0001] This utility model relates to the field of camera accessory technology, and in particular to a lens hood, a lens hood system, and a camera. Background Technology

[0002] A lens hood is a component of a lens's optical system. A lens has dozens of reflective surfaces, and the more reflective surfaces there are, the greater the impact on image quality. In backlit or side-backlit shooting, multiple reflective surfaces can interfere with each other, creating halos that dull colors or cause lens flare. Using a lens hood can suppress halos and prevent stray light from entering the lens, thus allowing the lens's optical potential to be fully realized. For better light-blocking, lens hoods are often rectangular in shape, matching the camera's image-capturing area.

[0003] Existing lens hoods typically have built-in microfiber cloth, which is used to fix the lens hood to the lens by friction between the fiber cloth and the outer periphery of the lens. However, this connection method is not stable enough, and the lens hood is easy to rotate. After rotating, the lens hood will block the area where the camera captures images, affecting shooting. Utility Model Content

[0004] The main purpose of this invention is to provide a lens hood that reduces the probability of the lens hood affecting camera shooting.

[0005] To achieve the above objectives, the present invention provides a light shield applied to a camera, the camera comprising a body and a lens, the lens being disposed on the body, and the light shield comprising:

[0006] A cover body, the cover body having a cover opening; and

[0007] A mounting ring is rotatably connected to the housing; the mounting ring is threaded for threaded connection with the lens.

[0008] Optionally, the mounting ring also has a stepped surface located at one end of the thread near the cover, the stepped surface being used to abut and limit the lens.

[0009] Optionally, the light shield further includes a scratch-resistant velvet cloth, which is disposed on the mounting ring and abuts against the stepped surface; the side of the scratch-resistant velvet cloth facing away from the stepped surface is used to abut against the lens.

[0010] Optionally, the mounting ring includes a first adapter ring and a fixing retaining ring. The first adapter ring is screwed to the lens barrel, and the fixing retaining ring is fixedly connected to the cover. The side of the first adapter ring facing the lens barrel has the stepped surface.

[0011] The inner wall of the first adapter ring is formed with a retaining ring, and the outer wall of the fixed retaining ring and the cover body form a retaining ring groove, and the retaining ring engages with the inner wall of the retaining ring groove.

[0012] Optionally, there is an installation gap between the retaining ring and the sidewall of the retaining ring groove.

[0013] Optionally, a protruding ring is formed at the end of the cover away from the cover opening, and the fixing retaining ring is screwed to the protruding ring; there is a rotational gap between the side wall of the first adapter ring facing the cover and the outer wall of the cover.

[0014] Optionally, the first adapter ring has a lubrication ring groove formed on the inner wall of the cover, and the lubrication ring groove is used to fill lubricant.

[0015] Optionally, the outer wall of the first adapter ring is formed with anti-slip texture.

[0016] Optionally, the light shield further includes a cover connected to the shield body and used to cover the shield opening.

[0017] This utility model also proposes a light-shielding system, the light-shielding system comprising:

[0018] A cover body, the cover body having a cover opening; and

[0019] A mounting ring is rotatably connected to the housing; the mounting ring is threaded for threaded connection with the lens.

[0020] This utility model also proposes a camera, the camera comprising:

[0021] A cover body, the cover body having a cover opening; and

[0022] A mounting ring is rotatably connected to the housing; the mounting ring is threaded for threaded connection with the lens.

[0023] In this invention, the lens hood includes a cover body and a mounting ring. The cover body has a cover opening; the mounting ring is rotatably connected to the cover body; the mounting ring has threads for threaded connection with the lens. In this invention, before installing the lens hood, the long side of the cover body extends in the same direction as the long side of the cover opening. During installation, only the mounting ring needs to be rotated to install the lens. This installation method allows the lens hood to be installed without rotating the cover body. After installation, the long side of the cover body will always extend in the same direction as the long side of the cover opening, thus preventing the lens hood from blocking the area where the camera captures images. Simultaneously, the lens and mounting ring are threaded together, ensuring that the lens hood and lens will not rotate relative to each other without external force, thus preventing the lens hood's rotation from affecting the camera's shooting. In summary, the lens hood provided by this invention can reduce the negative impact of the lens hood assisting the camera in shooting. Attached Figure Description

[0037] Please refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 5 To address the problem of lens hoods affecting camera shooting, this utility model proposes a lens hood 1000, applied to a camera 3000. The camera 3000 includes a body 5 and a lens 6, with the lens 6 disposed on the body 5. The lens hood 1000 includes:

[0038] The cover 1 has a cover opening 11; the mounting ring 2 is fixedly connected to the cover 1; the mounting ring 2 is rotatably connected to the cover 1; the mounting ring 2 is threaded, and the thread is used for threaded connection with the lens 6.

[0039] In this utility model's technical solution, before installing the lens hood 1000, the direction of the long side of the main body 5 extends in the same direction as the direction of the long side 111 of the cover opening 11. During installation, only the mounting ring 2 needs to be rotated to install the lens hood 1000 onto the lens 6. This installation method allows the lens hood 1000 to be installed without rotating the cover body 1. After installation, the direction of the long side of the main body 5 extends in the same direction as the direction of the long side 111 of the cover opening 11, thereby preventing the lens hood 1000 from blocking the area where the camera 3000 captures images. At the same time, the lens 6 is threadedly connected to the mounting ring 2, ensuring that the lens hood 1000 and the lens 6 will not rotate relative to each other without external force, thus preventing the rotation of the lens hood 1000 from affecting the shooting of the camera 3000. In summary, the lens hood 1000 provided by this utility model can reduce the negative impact of the lens hood 1000 assisting the camera 3000 in shooting.

[0040] In one embodiment, the mounting ring 2 also has a stepped surface 21, which is located at the end of the thread near the cover 1. The stepped surface 21 is used to abut against and limit the lens 6. When the lens 6 abuts against the stepped surface 21 of the mounting ring 2, the stepped surface 21 limits the lens 6, preventing the lens 6 from being screwed further into the mounting ring 2. At this point, it means that the light shield 1000 is installed, thus avoiding the lens 6 being installed too deeply and affecting the light shielding effect of the cover 1.

[0041] In one embodiment, the light shield 1000 further includes a scratch-resistant velvet cloth 3, which is disposed on the mounting ring 2 and abuts against the stepped surface 21; the side of the scratch-resistant velvet cloth 3 facing away from the stepped surface 21 is used to abut against the lens 6. Placing the scratch-resistant velvet cloth 3 on the end of the lens 6 facing the mounting ring 2 can protect the lens 6 during rotational installation and prevent the end face of the lens 6 from being scratched by the mounting ring 2.

[0042] The mounting ring 2 includes a first adapter ring 22 and a fixing retaining ring 23. The first adapter ring 22 is screwed to the lens barrel, and the fixing retaining ring 23 is fixedly connected to the housing 1. A stepped surface 21 is formed on the side of the first adapter ring 22 facing the lens barrel. The first adapter ring 22 and the fixing retaining ring 23 are engaged. Alternatively, the first adapter ring 22 may form a retaining ring groove 231, and the fixing retaining ring 23 may form a retaining ring 221; or the first adapter ring 22 may form a retaining ring 221, and the fixing retaining ring 23 may form a retaining ring groove 231. In one embodiment, the inner wall of the first adapter ring 22 forms a retaining ring 221, and the outer wall of the fixing retaining ring 23 surrounds the housing 1 to form a retaining ring groove 231. The retaining ring 221 engages with the inner wall of the retaining ring groove 231, so that the first adapter ring 22 and the fixing retaining ring 23 are engaged.

[0043] In one embodiment, there is an installation gap 2311 between the retaining ring 221 and the side wall of the retaining ring groove 231. The lens 6 is screwed to the first adapter ring 22. When the lens 6 is installed or removed, the lens 6 will move back and forth along the axis of the lens 6. The installation gap 2311 between the retaining ring 221 and the side wall of the retaining ring groove 231 ensures that the engagement of the retaining ring 221 and the retaining ring groove 231 will not hinder the movement of the lens 6.

[0044] In one embodiment, a protruding ring 12 is formed at the end of the cover 1 away from the cover opening 11, and a fixing retaining ring 23 is screwed to the protruding ring 12; there is a rotational gap 222 between the side wall of the first transition ring 22 facing the cover 1 and the outer wall of the cover 1. The side wall of the first transition ring 22 facing the cover 1 does not contact the outer wall of the cover 1, so that no friction is generated between the side wall of the first transition ring 22 facing the cover 1 and the cover 1, avoiding resistance from the side wall of the first transition ring 22 when the fixing retaining ring 23 is screwed to the protruding ring 12, thereby making the installation of the fixing retaining ring 23 and the cover 1 smoother. It is understood that, in order to make the connection between the fixing retaining ring 23 and the cover 1 more secure, glue is often filled into the gap between the fixing retaining ring 23 and the protruding ring 12 after the fixing retaining ring 23 is screwed to the protruding ring 12.

[0045] In one embodiment, the first adapter ring 22 has a lubrication ring groove 223 formed on the inner wall of the cover 1. The lubrication ring groove 223 is used to fill with lubricant, which makes the installation of the cover 1 and the fixed retaining ring 23 smoother.

[0046] Damping oil is generally used as a lubricant. Similarly, other materials such as grease can also be used as lubricants.

[0047] In one embodiment, the outer wall of the first adapter ring 22 is formed with anti-slip texture 224. This increases the friction of the outer wall of the first adapter ring 22, preventing the user from slipping when turning the first adapter ring 22, and making it easier for the user to install and remove the sunshade 1000.

[0048] In one embodiment, the light shield 1000 further includes a cover 4, which is connected to the shield body 1 and is used to cover the shield opening 11. The cover 4 covers the shield opening 11 to prevent foreign objects from entering from the shield opening 11, thereby protecting the lens 6 from damage.

[0049] Please refer to Figure 4This utility model also proposes a light-shielding system 2000, which includes a second adapter ring 7, a filter 8, and a light-shielding cover 1000. The second adapter ring 7 is connected to the end of the mounting ring 2 away from the cover 1, and the end of the second adapter ring 7 away from the mounting ring 2 is used to connect to the lens 6. The filter 8 is connected to the second adapter ring. The specific structure of the light-shielding cover 1000 is as described in the above embodiments. Since this light-shielding system 2000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. Of course, the connection between the second adapter ring 7 and the lens 6, and the connection between the second adapter ring 7 and the mounting ring 2, can be a threaded connection or a snap-fit ​​connection, etc.

[0050] It is understood that the connection between the filter 8 and the second adapter ring 7 can be either detachable or fixed. In one embodiment, the filter 8 and the second adapter ring 7 are detachable to facilitate the replacement of the filter 8.

[0051] This utility model also proposes a camera 3000, which includes a body 5, a lens 6, and a light-blocking system 2000. The specific structure of the light-blocking system 2000 is as described in the above embodiments. Since this camera 3000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
