Embodiment Construction
[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0029] Such as figure 1 As shown, is a structural schematic diagram of the low-rotating-speed moisture-proof sealing structure in the illustrative embodiment.
[0030] The low-speed moisture-proof sealing structure in the embodiment includes: a rotatable driven gear 8, a glass plate 6, a casing arranged on the periphery of the driven gear 8, and an annular nylon cover 3, and the casing includes: a front cover that is fixed in sequence 10. The bearing seat 11 and t...

The present invention proposes a low-speed moisture-proof sealing device and a dust-removing camera. The low-speed moisture-proof sealing structure includes: a rotatable driven gear and a casing arranged on the periphery of the driven gear. The casing includes: a front cover that is sequentially connected, It is used to support the bearing seat and the rear cover of the driven gear; the front cover is provided with an inwardly bent folding platform, and the inner surface of the folding platform of the front cover and the outer surface of the driven gear adopt clearance fit; the bearing seat and the driven gear are provided with There are bearings; the ring-shaped nylon cover is located between the inner side of the folding table of the front cover and the bearing, and is sleeved on the periphery of the driven gear. The present invention also relates to a dust-removing camera including the above-mentioned low-speed moisture-proof sealing structure. The low-speed moisture-proof sealing structure in the present invention can be used in any low-speed and low-torque sealing structure to achieve dustproof and waterproof effects.
Description
technical field [0001] The invention relates to the field of camera lens dust-proof technology, in particular to a low-speed moisture-proof sealing structure and a dust-removing camera. Background technique [0002] At present, in an environment with a high concentration of dust and water vapor, the glass mirror at the front of the camera lens will adhere to the water vapor and dust in the air, polluting the mirror, blurring the image collected by the camera, and affecting the quality of the collection. [0003] In order to solve this problem, a housing is added outside the camera, and a rotatable glass plate is installed on the housing corresponding to the camera lens. A cleaning device is fixed on the outside of the glass plate to realize automatic cleaning. A gap is used between the housing and the rotating inner housing. Cooperate, but the sealing effect of this structure is poor, and a small amount of water vapor and dust will enter the shell. Contents of the inventio...
