Description

Technical Field

[0001] The utility model relates to the technical field of shading plates, in particular to a shading plate. Background Art

[0002] A camera sunshade is a product that is installed on the front of a photographic lens, digital camera, or camcorder. Its main function is to block unwanted light or shadows, helping the photographer to more precisely control the shooting environment. A sunshade can be an opaque plate used to block light, block light, and reflect light. In photography, a sunshade or lens hood can block harmful light, and when a sunshade is used to reflect or refract light, it can also be called a reflector. Smaller sunshades may be called sunshades or sunshade strips. They are usually placed between the light source and the subject to block out some of the light, thereby affecting the distribution and intensity of the light.

[0003] In the optical lens industry, the inner diameter cross-section of the light hole of the sunshade is mostly a circular surface or an inclined surface. When shooting against the light, when the light shines on the circular surface or the inclined surface, the light is easily reflected to the lens, resulting in the Flare phenomenon. The Flare phenomenon is the multiple reflections of strong light in the lens, which reduces the image contrast, causes the image to turn white and form a halo phenomenon; at the same time, the buffering protection performance of most sunshades is insufficient, so that when the camera falls, the sunshade cannot effectively buffer the lens.

The inner ring of the fixing ring 42 is fixedly sleeved on the outside of the light-shielding tube 5. One end of the guide rod 44 is fixedly connected to one side of the limit plate 41, and the fixing ring 42 is located between the limit plate 41 and the anti-collision ring 46.

[0025] Furthermore, when the camera accidentally falls, the anti-collision ring 46 is installed on the ground, the camera lens 2 pushes the light-shielding tube 5, and the light-shielding tube 5 pushes the fixed ring 42, so that the fixed ring 42 moves toward the anti-collision ring 46. During this process, the fixed ring 42 compresses the buffer spring 45, and then the buffer spring 45 absorbs the energy generated by the impact, effectively reducing the damage to the camera lens 2 and protecting the camera lens 2.

[0026] Furthermore, the inner diameter section of the light shielding tube 5 is a wavy surface 51. The inner diameter section of the light shielding tube 5 is a wavy surface 51, which changes the diffraction form of light to change the propagation direction of light, effectively reduces strong light being reflected into the lens, and effectively prevents and alleviates Flare defects.

[0027] The connecting assembly 3 includes: a connecting tube 37, a circular through hole 36 is opened on the top of the connecting tube 37, the hole wall of the circular through hole 36 is slidably connected to the side of the positioning rod 34, the top end of the positioning rod 34 is fixedly connected to the bottom end of the pull rod 33, and the top end of the pull rod 33 is fixedly connected to the outside of the pull ring 31.

[0028] The side of the pull rod 33 is slidably inserted into the interior of the U-shaped frame 32 , and the bottom of the U-shaped frame 32 is fixedly connected to the exterior of the connecting tube 37 .

[0029] The side of the pull rod 33 is slidably inserted into the inner ring of the return spring 35 , and both ends of the return spring 35 are supported between the positioning rod 34 and the U-shaped frame 32 .

[0030] The inner ring of the connecting tube 37 is fixedly connected to the outside of the light-shielding tube 5, and the inner ring of the connecting tube 37 is also slidably sleeved on the outside of the camera lens 2. The outside of the camera lens 2 is provided with a positioning blind hole 1, and the hole wall of the positioning blind hole 1 is slidably sleeved on the outside of the positioning rod 34.

[0031] Furthermore, the connecting tube 37 is first sleeved on the outside of the camera lens 2. Before the connecting tube 37 is sleeved on the outside of the camera lens 2, the pull ring 31 is first pulled, and the pull ring 31 drives the pull rod 33, and the pull rod 33 drives the positioning rod 34 to move upward, so that the positioning rod 34 is pulled out from the inner circle of the connecting tube 37 to avoid hindering the camera lens 2 from being inserted into the connecting tube 37. After the camera lens 2 is inserted into the connecting tube 37 and the positioning blind hole 1 is aligned with the circular through hole 36, the pull ring 31 can be loosened at this time, and the reset spring 35 pushes the positioning rod 34 to be reinserted into the circular through hole 36 and the positioning blind hole 1, so that the connecting tube 37 cannot be separated from the camera lens 2, thereby realizing the rapid installation of the sunshade and the camera lens 2; when the sunshade needs to be removed, it is only necessary to pull the pull ring 31 to pull the positioning rod 34 out of the positioning blind hole 1, so that the sunshade can be removed from the camera lens 2, making the removal of the sunshade faster and more convenient to use.

[0032] Working principle: When in use, the sunshade is installed on the camera lens 2, and the connecting tube 37 is first sleeved on the outside of the camera lens 2. Before the connecting tube 37 is sleeved on the outside of the camera lens 2, the pull ring 31 is pulled first, and the pull ring 31 drives the pull rod 33, and the pull rod 33 drives the positioning rod 34 to move upward, so that the positioning rod 34 is pulled out from the inner circle of the connecting tube 37 to avoid hindering the camera lens 2 from being inserted into the connecting tube 37. After the camera lens 2 is inserted into the connecting tube 37 and the positioning blind hole 1 is aligned with the circular through hole 36, the pull ring 31 can be loosened at this time, and the reset spring 35 pushes the positioning rod 34 to be reinserted into the circular through hole 36 and the positioning blind hole 1, so that the connecting tube 37 cannot be separated from the camera lens 2; when it is necessary to remove the sunshade, just pull the pull ring 31 to pull the positioning rod 34 out of the positioning blind hole 1, so that the sunshade can be removed from the camera lens 2.

[0033] When the camera accidentally falls, the anti-collision ring 46 is installed on the ground, the camera lens 2 pushes the light-shielding tube 5, and the light-shielding tube 5 pushes the fixed ring 42, so that the fixed ring 42 moves toward the anti-collision ring 46. During this process, the fixed ring 42 compresses the buffer spring 45, and then the buffer spring 45 buffers and absorbs the energy generated by the impact, effectively reducing the damage to the camera lens 2 and protecting the camera lens 2.
