Description

Technical Field

[0001] The present invention relates to the technical field of cameras, and particularly to a camera lens filter assembly that is easy to disassemble and assemble. Background Art

[0002] Camera lens filters are widely used in photography technology and are also known as lens filters or photographic filters. In addition to providing protection for camera lenses, camera lens filters are also used to modify the images captured by cameras, including enhancing colors, reducing reflections, or helping to capture landscapes under extremely difficult lighting conditions.

[0003] Currently, camera lens filters are often mounted on camera lenses. Sometimes, to achieve better effects, multiple camera lens filters are mounted or the filters are replaced. It is difficult to disassemble and assemble camera lens filters outdoors. Existing filters often require tools such as filter wrenches to disassemble and assemble to ensure that the camera lens or the filter itself is not damaged. Disassembling and assembling without tools is difficult and prone to improper operation, which may damage the camera lens or the filter. Summary of the Invention

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figure 1 and Figure 2 shown, the embodiments of the present invention provide an easily detachable and installable camera lens filter assembly, including: a frame, a support ring and a filter; the inner peripheral surface of the frame is connected to the support ring, a positioning groove is provided on the support ring for installing the filter; an internal thread is further provided on the inner peripheral surface of the frame for installing the camera lens filter assembly on the camera lens; wherein, a plurality of protrusions are provided on the outer peripheral surface of the frame for increasing the friction of the frame.

[0022] By providing a plurality of protrusions on the outer peripheral surface of the frame, the friction of the frame can be increased. When loading and unloading the frame by hand, no tools are needed, which is more convenient to use. The number of protrusions is multiple, and no special positioning is required during loading and unloading, which is convenient to use. The setting of multiple protrusions can also increase the strength and stiffness of the frame.

[0023] Preferably, the plurality of protrusions are spaced apart on the outer peripheral surface of the frame.

[0024] A plurality of protrusions are arranged at intervals. On the one hand, it can increase the friction force. On the other hand, when the friction force is still insufficient, rod-shaped objects or other objects can be added at the interval positions to borrow force, so as to rotate the frame and achieve the purpose of loading and unloading.

[0025] Preferably, the height of the protrusion relative to the outer peripheral surface of the frame is 2 mm to 5 mm.

[0026] Preferably, the frame is made of brass. The brass body is beneficial to increasing the wear resistance of the frame and prolonging the service life of the frame. Moreover, using a brass body, it is wear-resistant as a whole. Compared with the wear-resistant layer, there will be no problem of falling off, and the service life is greatly extended.

[0027] Preferably, the frame is provided with an electroplated layer, and the electroplated layer is a matte electroplated layer. Using a matte electroplated layer is beneficial to reducing the reflection of the frame to the filter and improving the imaging effect of the camera.

[0028] Preferably, the electroplated layer is black or gray. The black or gray electroplated layer is beneficial to reducing the reflection of the frame to the filter and improving the imaging effect of the camera.

[0029] Preferably, the end face and / or the outer peripheral surface of the frame are provided with disassembly holes for inserting rod-shaped objects.

[0030] As Figure 2 shown, when disassembly holes are provided on the end face and / or the outer peripheral surface of the frame, force can be borrowed by inserting rod-shaped objects, so that when the friction force of the protrusions is insufficient, the convenience of installing and removing the filter can be further increased.

[0031] In some embodiments, the disassembly holes are provided on the protrusions. In other embodiments, the disassembly holes are provided at the interval positions between the protrusions.

[0032] At the same time, only setting the disassembly holes without directly adding rod-shaped objects is beneficial to simplifying the structure on the one hand, and can also avoid the existence of protrusions on the frame that affect the installation of the camera lens hood or the overall portability of the filter assembly. The setting of the disassembly holes is also beneficial for users to obtain materials locally, insert rod-shaped objects such as keys, screws, and branches into the disassembly holes, and increase the force arm to borrow force.

[0033] Preferably, the disassembly hole is any one of the following: through hole, blind hole or threaded hole.

[0034] When the disassembly hole adopts a blind hole or a through hole, the structure is simple and easy to operate. When the disassembly hole adopts a threaded hole, on the one hand, the screw can be screwed in to borrow force, and on the other hand, objects such as keys and branches can also be inserted and the thread can be used for anti-slip.

The plurality of protrusions help increase the friction between the camera lens filter and the fingers when disassembling and assembling the camera lens filter, facilitating the disassembly and assembly of the camera lens filter without tools. The external filter mounting thread is used to mount the lens filter onto the camera lens.

[0036] Preferably, the annular traction frame is made of brass, which is more wear-resistant than aluminum and has a longer service life.

[0037] Preferably, the annular traction frame is electroplated with a black matte surface, and the black matte surface reduces the light reflection that the annular traction frame may cause.

[0038] In one embodiment, as Figure 1 shown, an easily detachable camera lens filter 1 includes: an annular traction frame 2, protrusions 3, a support ring 4, a filter 5, an external filter mounting internal thread 6, and a disassembly hole 7. Among them, a plurality of protrusions 3 are provided on the entire circumference of the annular traction frame 2. The annular traction frame 2 is connected to a circular support ring 4 for supporting the filter 5. A positioning groove for positioning the filter glass 5 is provided on the circular support ring 4. The plurality of protrusions 3 on the annular traction frame 2 are 2-5 mm higher than the annular traction frame 2. The plurality of protrusions 3 help increase the friction between the camera lens filter 1 and the fingers when disassembling and assembling the camera lens filter 1, facilitating the disassembly and assembly of the camera lens filter 1 without tools. The external filter mounting thread 6 is used to mount the lens filter 1 onto the camera lens. The disassembly hole 7 is used to insert a rod-shaped object to increase the lever arm for borrowing force.

[0039] Preferably, the annular traction frame 2 is made of brass, which is more wear-resistant than aluminum and has a longer service life.

[0040] Preferably, the annular traction frame 2 is electroplated with a black matte surface, and the black matte surface reduces the light reflection that the annular traction frame 2 may cause.

[0041] The beneficial effects of the present invention are as follows: Without using a filter wrench, the camera lens filter can be easily disassembled and assembled. The structural strength of the filter outer frame is enhanced without sacrificing portability.
