Disclosure of Invention
The utility model aims to solve the problem of providing the dustproof double-filter switcher lens base, which can reduce dust accumulation on a circuit board chip, ensure that the shooting of a camera is clear and ensure that the heat dissipation of the chip is good.
The lens seat comprises a base plate and a lens connecting sleeve arranged at the top of the base plate, an outer frame body is arranged at the periphery of the bottom plate, a slot communicated with the inside of the lens connecting sleeve is arranged at one end of the bottom plate, a light-transmitting through groove communicated with the slot is formed in the bottom plate in a penetrating mode, a transparent dustproof sheet for closing the light-transmitting through groove is arranged on the light-transmitting through groove, and a dustproof frame body communicated with the light-transmitting through groove is arranged at the bottom of the bottom plate and positioned at the inner side of the outer frame body.
Preferably, the transparent dust-proof sheet is glass.
Preferably, the transparent dustproof sheet is fixedly connected to the bottom of the bottom plate.
Preferably, the inner circumferential area of the dust-proof housing is gradually reduced from the bottom end to the top end side thereof.
Preferably, the opposite sides of the bottom plate are provided with connecting lugs, and the connecting lugs are provided with mounting screw holes.
The beneficial effects of the utility model are as follows: the utility model provides a dustproof double-filter switcher lens seat, which is characterized in that after a lens seat is arranged on a circuit board of a camera, an outer frame body is sleeved on the upper surface of the circuit board, the dustproof frame body is sleeved on a chip of the circuit board, dust can be reduced from entering the dustproof frame body and accumulating on the chip, and by arranging a transparent dustproof sheet on a transparent through slot, powder generated in the process of switching a movable sheet in the slot is prevented from falling on the chip through the transparent through slot, so that a good dustproof effect can be achieved, dust accumulation on the chip of the circuit board is reduced, and the shooting clarity of the camera is ensured.
