Description
Technical Field
The utility model relates to an optical photographic equipment, in particular to little single camera lens hood.
Background
A light shield is a device installed at the front end of a photographing lens, a digital camera and a video camera to shield harmful light, and is one of the most commonly used photographing accessories. The shading cover is made of various materials such as metal, hard plastic, soft plastic and the like. Strictly speaking, the light shield is a component of the lens optical system. One lens is composed of a plurality of lenses or a dozen of lenses. Each lens has two reflective surfaces, and one lens has tens of reflective surfaces! The more reflecting surfaces the greater the influence on the imaging of the lens! Particularly, in the case of backlight or side backlight imaging, the plurality of reflecting surfaces interfere with each other to form a halo. The lens hood can inhibit stray light from entering the lens, so that fog is eliminated, and the imaging definition and color restoration are improved. However, in the prior art, since the light shield is installed at the front end of the lens, at this time, if the filter needs to be installed, it is troublesome, which easily causes the problems of heavy lens and inaccurate installation position of the filter.

Further, be equipped with annular groove on the inside wall of the second end of lens hood body, be equipped with the annular arch of radial outside extension on the filter, the filter passes through annular protruding joint in the annular groove.
Further, the magnetic part is arranged in the annular groove.
Furthermore, at least two buckles are hinged on the outer side wall of the light shield body; when the filter is installed, the filter is buckled on the lens hood body after the buckle clamp rotates.
Further, the micro single camera lens hood is a cylindrical lens hood.
Further, the inner side wall of the light shield body is sprayed with a black coating with low reflectivity.
By adopting the technical scheme, the magnetic suction part is arranged at one end of the light shield, the filter can be adsorbed on the magnetic suction part, the filter can be quickly and simply installed, the problem of heavy lens caused by a complex installation structure is solved, and the filter is suitable for various lenses. Convenient disassembly and two functions of shading and filtering.

Detailed Description
The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Referring to fig. 1 to 4, the technical solution of this embodiment is a micro single-camera lens hood, which includes a lens hood body 1 and a filter 2, wherein one end of the lens hood body 1 is provided with a bayonet 11 connected with a lens, a second end of the lens hood body 1 is provided with a magnetic attraction portion, and the filter 2 is installed at a second end of the lens hood body 1 through the magnetic attraction portion.
By adopting the technical scheme, the magnetic suction part is arranged at one end of the light shield, the filter 2 can be adsorbed on the magnetic suction part, so that the filter 2 can be quickly and simply installed, and the problem of heavy lens caused by the avoided complex installation structure is suitable for various lenses. Convenient disassembly and simultaneously realizes two functions of shading and filtering 2.
In the first embodiment, the second end of the light shield body 1 is provided with an annular groove, the filter 2 is provided with an annular protrusion 21 matched with the annular groove, and the annular protrusion 21 is embedded in the annular groove in a clamping manner. Wherein, the magnetic part is arranged in the annular groove. The filter 2 is quickly mounted through the grooves in the end heads, so that the mounting process is more convenient and faster.
In the second embodiment, an annular groove is formed in the inner side wall of the second end of the light shield body 1, an annular protrusion 21 extending radially outwards is formed on the filter 2, and the filter 2 is clamped in the annular groove through the annular protrusion 21. Wherein the magnetic part is arranged in the annular groove. . Set up the recess on the inside wall through the lens hood is local, realize filter 2's joint for filter 2's installation is more firm, in order not to take place to drop.
Of course, the position of the annular groove 12 may be other than those of the above two embodiments, and the structure thereof is not limited to that described in the embodiment.
On the basis of the technical scheme of the first embodiment, at least two buckles 13 are hinged on the outer side wall of the light shield body 1; when the lens hood is installed, the buckle 13 is rotated to buckle the filter 2 on the lens hood body 1. The filter 2 is buckled through two or more clamping holes, so that the filter 2 is firmly installed and is prevented from falling off.
