[0021] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0022] Embodiments of this application provide a light shield and a filter assembly.

[0023] The light shield includes: a light shield body 100, a filter mounting part 300, and an adapter ring mounting part 200.

[0024] The filter mounting part 300 is used to mount filters. The filter mounting part 300 is rotatably connected to the side of the light shield body 100 where the light shield plate 110 is provided. Part of the filter mounting part 300 is exposed from the side notch of the light shield body 100. The side of the light shield body 100 away from the filter mounting part 300 is rotatably connected to the adapter ring mounting part 200 for mounting the adapter ring. The light shield body 100 is provided with a locking member 400 for locking the rotation of the adapter ring mounting part 200.

[0025] A raised ring is provided on the outer side of the filter mounting part 300, and a groove is provided on the inner side of the light shield body 100. The raised ring on the outer side of the filter mounting part 300 is inserted into the groove on the inner side of the light shield body 100, so that the filter mounting part 300 can rotate along the groove.

[0026] In this embodiment, the user installs the filter onto the filter mounting part 300 and the lens hood onto the camera lens. When it is necessary to adjust the filter angle, the filter mounting part 300 can be rotated by rotating the part of the filter mounting part 300 exposed from the side notch of the lens hood body 100, thereby rotating the filter mounted on the filter mounting part 300 and adjusting the filter angle.

[0027] The user installs the adapter ring onto the adapter ring mounting part 200, and then uses the adapter ring to install the lens of the photographic equipment. The adapter ring mounting part 200 is rotatably connected to the lens hood body 100. After the lens hood is installed on the lens, the lens hood body 100 can be rotated to adjust the position of the lens hood 110.

[0028] After adjusting the position of the lens hood body 100, the locking member 400 can be used to lock the adapter ring mounting part 200 from rotating, so that the lens hood body 100 will not rotate relative to the lens.

[0029] The light shield includes a frame, and the light shield 110 includes a first plate 111 and a second plate 112. The first plate 111 and the second plate 112 are respectively disposed on opposite sides of the frame, and a side notch is formed between the first plate 111 and the second plate 112.

[0030] For example, a first plate 111 is disposed on the upper edge of the frame and protrudes outward from the frame; a second plate 112 is disposed on the lower edge of the frame and protrudes outward from the frame; the outer side of the frame is the side facing the lens, and the inner side of the frame is the side facing the lens. A side notch is formed between the first plate 111 on the upper edge of the frame and the second plate 112 on the lower edge of the frame. When the user needs to adjust the filter angle, the user can rotate the filter mounting part 300 exposed from the side notch of the lens hood body 100 by rotating the filter mounting part 300 with their finger, thereby rotating the filter mounted on the filter mounting part 300 and adjusting the filter angle.

[0031] The filter mounting section 300 is equipped with a magnetic component inside. The magnetic component is a permanent magnet such as a magnet. The filter can be magnetically connected to the filter through the magnetic component inside the filter mounting section 300, making it easy to install and remove the filter.

[0032] The filter mounting part 300 is provided with anti-slip teeth 310 on its side. The anti-slip teeth 310 can increase the friction between the finger and the filter mounting part 300, making it easier for the user to rotate the filter mounting part 300.

[0033] The main body 100 of the sunshade is provided with a through hole, and the locking member 400 is threaded into the through hole; when the locking member 400 abuts against the adapter ring mounting part 200, the locking member 400 locks the adapter ring mounting part 200 from rotating.

[0034] For example, the locking member 400 is screw-shaped; the side of the screw head of the locking member 400 is provided with anti-slip texture to facilitate the user to rotate the locking member 400. The screw of the locking member 400 is threaded into a through hole.

[0035] When the user tightens the locking member 400, the locking member 400 moves towards the adapter ring mounting portion 200. When the locking member 400 abuts against the adapter ring mounting portion 200, it locks the adapter ring mounting portion 200, preventing the sunshade body from rotating relative to the adapter ring mounting portion 200. When the user loosens the locking member 400, it moves away from the adapter ring mounting portion 200. When the locking member 400 no longer abuts against the adapter ring mounting portion 200, the sunshade body can rotate relative to the adapter ring mounting portion 200.

[0036] Reference Figure 4 and Figure 5 Additionally, a limiting member 420 is provided on the side of the sunshade body 100, and a locking member 400 passes through the limiting member 420. The limiting member 420 is used to restrict the range of motion of the locking member 400. Specifically, the limiting member 420 is arch-shaped, and its two legs are fixed to the side of the sunshade body 100 by positioning screws 421. A hole is provided in the middle of the limiting member 420, through which the locking member 400 passes. There is a space for movement between the middle of the limiting member 420 and the side of the sunshade body 100. The nut portion of the locking member 400 is provided with a protrusion 410, which is located in the space for movement. The protrusion 410 cannot pass through the hole in the middle of the limiting member 420, thereby limiting the range of motion of the locking member 400 to the allowable range of movement and preventing the locking member 400 from falling off and being lost from the sunshade body 100.

[0037] The main body 100 of the sunshade is provided with an adapter ring fixing part 500 for fixing the adapter ring.

[0038] The adapter ring fixing component 500 includes a spring clip 510, a spring 540, a screw 530, and a pin 520. The sunshade body 100 is provided with a mounting cavity. The pin 520 passes through the mounting cavity and the spring clip 510. The spring clip 510 is installed on the mounting cavity and slides along the pin 520. The screw 530 fixes the spring 540 in the mounting cavity. One end of the spring 540 abuts against the spring clip 510.

[0039] In this embodiment, due to the elastic force of the spring 540, part of the snap 510 protrudes inward toward the adapter ring mounting portion 200. When the adapter ring is installed onto the adapter ring mounting portion 200, the protruding part of the snap 510 locks the adapter ring onto the adapter ring mounting portion 200.

[0040] When it is necessary to remove the adapter ring from the adapter ring mounting part 200, slide the spring clip 510 outwards from the adapter ring mounting part 200. The spring clip 510 slides along the pin 520 outwards from the adapter ring mounting part 200 until the spring clip 510 no longer holds the adapter ring. At this point, the adapter ring can be removed from the adapter ring mounting part 200. When the user releases the spring clip 510, the spring clip 510 slides along the pin 520 inwards from the adapter ring mounting part 200 under the elastic force of the spring 540.

[0041] When the adapter ring needs to be installed onto the adapter ring mounting part 200, slide the spring clip 510 outwards from the adapter ring mounting part 200. The spring clip 510 slides along the pin 520 outwards from the adapter ring mounting part 200 until the spring clip 510 is completely separated from the inside of the adapter ring mounting part 200. At this point, the adapter ring can be installed onto the adapter ring mounting part 200. After the adapter ring is installed onto the adapter ring mounting part 200, the user releases the spring clip 510. Under the elastic force of the spring 540, the spring clip 510 slides along the pin 520 inwards from the adapter ring mounting part 200.

[0042] The inner side of the light-shielding plate 110 is provided with threads.

[0043] The filter assembly includes a filter, an adapter ring, and a light shield as described above. The filter is magnetically connected to the filter mounting part 300 of the light shield, and the adapter ring is mounted on the side of the light shield body 100 away from the filter.

[0044] In this embodiment, the user installs the filter onto the filter mounting part 300 and the lens hood onto the camera lens. When it is necessary to adjust the filter angle, the filter mounting part 300 can be rotated by rotating the part of the filter mounting part 300 exposed from the side notch of the lens hood body 100, thereby rotating the filter mounted on the filter mounting part 300 and adjusting the filter angle.

[0045] The user installs the adapter ring onto the adapter ring mounting part 200, and then uses the adapter ring to install the lens of the photographic equipment. The adapter ring mounting part 200 is rotatably connected to the lens hood body 100. After the lens hood is installed on the lens, the lens hood body 100 can be rotated to adjust the position of the lens hood 110.

[0046] After adjusting the position of the lens hood body 100, the locking member 400 can be used to lock the adapter ring mounting part 200 from rotating, so that the lens hood body 100 will not rotate relative to the lens.

[0047] The above is a detailed description of the preferred embodiments of this application, but this application is not limited to the embodiments.
