Example 1

The present embodiment provides a dustproof lens, referring to fig. 1 to 3, which includes a lens barrel 1, a lens 3, and a dustproof assembly.

The lens 3 is arranged in the lens barrel 1, specifically, an annular clamping groove 2 is arranged in the lens barrel 1, and the lens 3 is clamped and fixed in the clamping groove 2; the dustproof assembly comprises an inner ring 4, an outer ring 5, a glass blocking piece 6 and a dustproof sleeve 8; the inner ring 4 is sleeved outside the lens cone 1, the outer ring 5 is detachably sleeved outside the inner ring 4, one end, far away from the lens cone 1, of the outer ring 5 is bent inwards to form a right-angle bending part 15, and the glass blocking piece 6 is clamped between the inner ring 4 and the right-angle bending part 15. The inward extending distance of the right-angle bending part 15 is not enough to shield the lens, and the lighting and imaging of the lens are not affected.

Referring to fig. 2, one end of the outer ring 5 close to the lens barrel 1 (i.e., the end of the outer ring 5 sleeved on the lens barrel 1) is bent inward to form an arc-shaped bending portion 7, the arc-shaped bending portion 7 is clamped outside the lens barrel 1, the arc-shaped bending portion 7 does not scratch the lens barrel 1, and the inner ring 4 is located inside the arc-shaped bending portion 7. The outer ring 5 is made of an elastic material, for example, the outer ring 5 is made of rubber. The left end face of the glass baffle 6 is attached to the inner ring 4, and the right end face is attached to the right-angle bent portion 15.

When using dustproof camera lens, 5 chucking of outer ring circle are fixed and are compressed tightly inner ring circle 4 and glass separation blade 6 with inside on lens cone 1, prevent that glass lens 3 from rocking or dropping in the use, and outer ring circle 5 plays sealed effect simultaneously, prevents that the dust from getting into inside glass separation blade 6. Preferably, the inner ring 4 is also a rubber ring, which can further improve the sealing performance at the glass baffle 6 and prevent dust from entering. The dustproof lens is used up, the dustproof sleeve 8 is sleeved outside the outer ring 5, the inner surface of the dustproof sleeve 8 is attached to the outer surface of the outer ring 5, the dustproof sleeve 8 protects the glass blocking piece 6 in a dustproof mode when dust on the glass blocking piece 6 is less or no dust exists, and the dustproof sleeve 8 can be taken down when the dustproof sleeve is used again.

When dust on the glass blocking piece 6 is accumulated to a certain degree to influence normal imaging, the arc-shaped bending part 7 in the front of the outer ring 5 is outwards broken, the outer ring 5 is taken down, then the glass blocking piece 6 is taken down for cleaning, the glass blocking piece 6 can be cleaned at any time, next use is ensured, recycling is realized, and waste is avoided; the glass blocking piece 6 is convenient to disassemble and clean, the cleanliness of the glass blocking piece can be guaranteed, and the imaging quality is guaranteed. A light-transmitting film (not shown) is bonded to the outer surface (i.e., the right end surface in fig. 2) of the glass barrier 6 to increase the light transmittance of the lens 3.

The dust assembly further comprises a first main clasp 9, a second main clasp 11, a spring cord 10, a first secondary clasp 12, a second secondary clasp 14 and a pull cord 13. The first main retaining ring 9 is fixed on the lens barrel 1, the second main retaining ring 11 is fixed on the outer ring 5, small holes are formed in the middle of the first main retaining ring 9 and the middle of the second main retaining ring 11, and two ends of the spring rope 10 are respectively fixed in the small holes of the first main retaining ring 9 and the second main retaining ring 11 in a penetrating mode. The first retaining ring 12 is fixed on the outer ring 5, the second retaining ring 14 is fixed on the dust-proof sleeve 8, small holes are formed in the first retaining ring 12 and the second retaining ring 14, and two ends of the traction rope 13 are respectively fixed in the small holes of the first retaining ring 12 and the second retaining ring 14 in a penetrating mode.

When the dustproof lens is used, some parts which are separated from the main body and cannot influence the functions and use of the device are easy to lose, the outer ring 5 is connected to the lens barrel 1 through the arrangement of the first main retaining ring 9, the second main retaining ring 11 and the spring rope 10, when the outer ring 5 is taken down, the outer ring 5 can be prevented from losing, and the time for searching the outer ring 5 when the outer ring 5 is required to be used is saved. Similarly, the dust boot 8 is prevented from being lost by attaching the dust boot 8 to the outer ring 5 by the arrangement of the first and

second clasps

12, 14 and the pulling string 13. Therefore, the situation that the equipment is found when parts need to be used or the equipment is lost to influence the next use of the equipment is avoided.

When the dustproof lens is used, the glass blocking piece 6 is sealed and shielded outside the lens 3 through the inner ring 4 and the outer ring 5, so that the lens 3 is prevented from being directly exposed in the air when in use, the outer ring 5 is detached after dust is accumulated on the glass blocking piece 6, the glass blocking piece 6 can be taken down to be cleaned in time, the lens is remounted outside the lens 3 after cleaning is completed, the glass blocking piece 6 is convenient to detach and clean, the lens 3 and the glass blocking piece 6 can be kept clean, and the imaging effect is ensured; and use dustproof camera lens under outdoor extreme weather, avoid lens 3 to contact external adverse circumstances, reduce the influence of environment to lens 3, improve lens 3's life.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
