Embodiment Construction

[0027] Such as Figure 5 and Figure 6 As shown, the dustproof cover structure 100 of the present invention includes a dustproof base 101 , an annular inner link 102 , an annular outer link 103 , a first feather 104 and a second feather 105 . The dustproof base 101 is provided with a central hole 106 to form a ring shape; the central hole 106 is used to allow light to pass through and enter the lens. The dust-proof base 101 includes a first surface 107 and a second surface 108 , and a protruding inner ring 109 is provided on the first surface 107 . The inner ring 109 extends outward from the inner diameter surface of the dustproof base 101 . The inner connecting rod 102 is sleeved outside the inner ring 109, and the outer connecting rod 103 is sleeved outside the inner connecting rod 102, and the three are concentric.

[0028] On the second surface 108, the first feather 104 and the second feather 105 are provided. refer to Figure 8 and Figure 10 , the first feather 10...

Abstract

The invention relates to a dustproof cover structure for a lens, which comprises: a dustproof base, which is provided with a central hole and comprises a first surface and a second surface; an inner connecting rod, which is rotatably arranged on the first surface of the dustproof base and is provided with a positioning column which extends from the first surface to the outside of the second surface of the dustproof base and can rotate along with the inner connecting rod; an outer connecting rod, which is rotatably sleeved outside the inner connecting rod and is provided with a quill closing action source; a quill, which is rotatably connected with the second surface of the dustproof base and is connected with the positioning column of the inner connecting rod; and a quill closing elastic component, which is connected between the inner connecting rod and the outer connecting rod and is used for driving the inner connecting rod to rotate in the rotating process of the outer connecting rod so as to close the quill. The dustproof cover structure is provided with the two connecting rods, the inner connecting rods is directly connected to two pieces of quills, and the two pieces of the quills are driven and closed by the same quill closing spring, thus the problem that the quills cannot be completely closed due to different quill closing forces in the prior art is overcome.

Description

technical field [0001] The invention relates to a lens assembly, more specifically, to a lens dustproof cover structure. Background technique [0002] At present, many image capture devices, such as mobile phone lenses, small cameras, and thin cameras, are equipped with a built-in dust cover (barrier) structure. When the camera lens is stored, the two feathers of the dust cover structure are closed, so that Cover the lens to prevent dust from falling. [0003] Such as Figure 1-4 As shown, the existing dustproof cover structure usually includes an annular dustproof base 1 with a central hole 2 for allowing light to pass through and enter the lens. The dustproof base 1 includes a first surface 3 and a second surface 4 . On the first surface 3 of the dustproof base 1 , there is provided a concentric annular connecting rod 5 , and two arc-shaped holes 6 penetrating from the first surface 3 to the second surface 4 and opposite to each other. On the ring-shaped connecting rod ...
