[ detailed description ] embodiments
In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.
It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
Referring to fig. 1, the present invention provides a light shielding device 100 for an outdoor explosion-proof camera.
In the embodiment of the present invention, the outdoor anti-explosion camera shading device 100 includes a silica gel shade 10 and a plastic lens ring 20.
Specifically, please refer to fig. 2 at the same time, the silica gel light shield 10 includes an outer ring 11, a middle ring 12, an inner ring 13, a transfer ring 14 and a sleeve ring 15, the outer ring 11, the middle ring 12, the inner ring 13, the transfer ring 14 and the sleeve ring 15 are connected in sequence, the inner diameters of the outer ring 11, the middle ring 12, the inner ring 13, the transfer ring 14 and the sleeve ring 15 are arranged in sequence from large to small, a first annular flange 21 is arranged on the outer surface of one end of the silica gel light shield 10 close to the plastic lens ring 20, a second annular flange 22 is arranged on the inner wall of one end of the plastic lens ring 20 far away from the silica gel light shield 10, and the sleeve ring 15 of the silica gel light shield 10 is sleeved on the plastic lens sleeve ring.
It will be appreciated that when the plastic lens ring 20 is mounted on the lens of the explosion-proof camera, it is required to rotate while being squeezed, and due to the presence of the second annular flange 22, when a "click" is heard, it indicates that it is fastened. The size of silica gel lens hood 10 is not of uniform size, and a plastic lens ring 20 can freely arrange multiple silica gel lens hood 10, first annular flange 21 can prevent silica gel lens hood 10 drops.
