Description

Technical Field

[0001] The invention relates to the technical field of optical fog-penetrating lenses, and in particular to an optical fog-penetrating lens with a protective structure. Background Art

[0002] A fog-penetrating lens refers to a lens that has a very high transmittance of long-wavelength light (700nm-950nm) in the infrared light field, and at the same time has the function of controlling the imaging surface (camera CCD target surface) of this high-wavelength light. By using this lens in conjunction with a high-performance day and night camera, even in visible light (color image) environments such as fog, dust, smoke, and light rain, ordinary lenses can only produce blurry images and the effective observation distance is greatly shortened. Under harsh conditions, very clear, high-contrast black and white images can be captured, thereby improving long-distance observation effects.

[0003] In the document (application number: CN202222678725.9), an optical fog-penetrating lens with a protective structure is disclosed, including a lens, a protective device is provided on the surface of the lens, and a control component is provided on the surface of the protective device. The optical fog-penetrating lens and the existing fog-penetrating lens both use a single lens. Since the fog-penetrating lens is generally used in foggy and rainy environments, it is easy to accumulate fog and water droplets on its surface after being exposed to foggy and rainy environments for a long time. The lens needs to be removed and cleaned before it can be used again. The fog-penetrating strength of the single fog-penetrating lens is fixed, which cannot meet the requirements of photographic works with unique styles or artistic effects. At the same time, the optical fog-penetrating lens and the existing fog-penetrating lens are simply protected and shielded when not in use. Due to the high air humidity in foggy and rainy days, fog and water droplets are also easy to form on the surface of the lens after it is covered. The protective effect is single, which affects the subsequent use of the lens. Summary of the invention

[0004] The purpose of the present invention is to solve the above problems and provide an optical fog-proof lens with a protective structure.

DETAILED DESCRIPTION

[0030] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0031] Embodiment 1, as Figure 1-Figure 8 As shown, an optical fog-proof lens with a protective structure comprises a lens mounting tube 1, the lens mounting tube 1 is rectangular, an outer hoop 2 is fixedly mounted on the outer side of the lens mounting tube 1, and sliding cavities 21 are arranged between the outer hoop 2 and the four sides of the lens mounting tube 1;

[0032] The top and both sides of the sliding cavity 21 are slidably connected with a lens slide plate 3 and a mist-penetrating mirror frame 4. The mist-penetrating mirror frame 4 is hinged on the front of the lens slide plate 3. A torsion spring 41 is provided at the hinge between the mist-penetrating mirror frame 4 and the lens slide plate 3. The three groups of mist-penetrating mirror frames 4 are all installed with mist-penetrating mirrors. The mist-penetrating strengths of the three groups of mist-penetrating mirrors are different.

[0033] The bottom sliding cavity 21 is internally slidably connected with a baffle slide 5, and a baffle 6 is hinged on the front of the baffle slide 5. A torsion spring 41 is also provided at the hinge between the baffle 6 and the baffle slide 5. The interior of the baffle 6 is designed to be hollow, and an inner bladder 63 is provided inside the baffle 6. Anti-fog agent is stored inside the inner bladder 63. A plurality of groups of spray holes 61 are arranged in a ring shape on the top of the baffle 6, and the spray holes 61 are connected with the inner bladder 63. A liquid filling port 62 is arranged at the bottom of the baffle 6, and the liquid filling port 62 is connected with the inner bladder 63. An airbag 9 is arranged between the baffle 6 and the baffle slide 5, and the airbag 9 is connected with the baffle 6 through a one-way exhaust valve. A one-way air inlet nozzle 91 is arranged on the outside of the airbag 9.

[0034] In rainy and foggy days, the air humidity is high and the external environment is complex. After a period of time, fog is easily generated on the fog-penetrating lens. Therefore, in order to extend the shooting time and have a smaller impact on the shooting time, the baffle plate slide 5 is pushed forward, and the baffle plate slide 5 drives the baffle plate 6 to slide out of the slide cavity 21. When the baffle plate 6 completely slides out of the slide cavity 21, the baffle plate 6 swings upward under the action of the torsion spring 41, and the baffle plate 6 blocks the front of the lens. At the same time, the baffle plate 6 squeezes the airbag 9, and the airbag 9 presses the gas into the baffle plate 6 through the one-way exhaust valve, and the air pressure inside the baffle plate 6 increases. The air pressure squeezes the inner bladder 63, and the anti-fog agent in the inner bladder 63 is sprayed on the lens surface to prevent fog and condensed water droplets from forming on the surface. Then, the baffle plate 5 is pulled backward first, and the baffle plate 6 swings relative to the baffle plate 5 under the obstruction of the lens mounting tube 1. The baffle plate 6 gradually swings to a horizontal position and enters the sliding cavity 21. At the same time, the airbag 9 is restored and air is inhaled through the one-way air inlet nozzle 91. The anti-fog agent spraying on one side can be completed by a quick push and pull, which can be completed in a very short time, has little impact on the shooting time, and can greatly extend the shooting time.

[0035] When the shooting demand changes, it is necessary to replace the fog mirror, first pull the lens slide plate 3 backward, the fog mirror frame 4 swings relative to the lens slide plate 3 under the obstruction of the lens mounting tube 1, the fog mirror frame 4 gradually swings to a horizontal level and enters the sliding cavity 21, and then pushes another group to drive by pushing the lens slide plate 3 toward the front, the lens slide plate 3 drives the fog mirror frame 4 to slide out of the sliding cavity 21, and under the action of the torsion spring 41, the fog mirror frame 4 swings to the position covering the lens, and the fog mirror can be quickly replaced by pushing and pulling the lens slide plate 3. At the same time, when the other group of fog mirrors does not return, the other group of fog mirrors can also be pushed out, so that fog mirrors with different fog penetration strengths can be stacked and used in combination to achieve different fog penetration effects. For photographic works with unique styles or artistic effects, stacking multiple fog-penetrating lenses can provide more expression space and richer shooting effects.

[0036] After the shooting is completed, the baffle plate 5 is pushed forward, and the baffle plate 5 drives the baffle plate 6 to slide out of the sliding cavity 21. When the baffle plate 6 completely slides out of the sliding cavity 21, the baffle plate 6 swings upward under the action of the torsion spring 41, and the baffle plate 6 blocks the front of the lens. When the lens is protected, the baffle plate 6 squeezes the air bag 9 at the same time, and the air bag 9 presses the gas into the baffle plate 6 through the one-way exhaust valve. The air pressure inside the baffle plate 6 increases, and the air pressure squeezes the inner bladder 63. The anti-fog agent in the inner bladder 63 is sprayed on the surface of the lens to prevent fog and condensed water droplets from being generated on the surface, which can improve the lens protection effect. When used next time, it can be directly opened for use;

[0037] It should be noted that the present invention can also set a fog-penetrating mirror in one of the fog-penetrating mirror frames 4, and set a UV filter and a polarizing filter in the other two fog-penetrating mirror frames 4. The UV filter can filter ultraviolet rays, and the polarizing filter can reduce reflection and improve color saturation, which can better increase the richness of the lens.

[0039] After the fog-proof frame 4 is swung to the position covering the lens, the knob 32 is turned, and the knob 32 drives the block 33 to rotate. When the block 33 rotates to the through-hole position, the retaining spring 34 pushes the block 33 through the through-hole and is inserted into the slot 24, thereby completing the locking of the lens slide 3 or the baffle slide 5, thereby improving the stability of use.

[0041] After the fog-permeable mirror frame 4 is swung to the position covering the lens, the knob 32 is turned, and the knob 32 drives the card block 33 to rotate. When the card block 33 rotates to the through-hole position, the retaining spring 34 pushes the card block 33 through the through-hole and is inserted in the card slot 24, thereby completing the locking of the lens slide plate 3 or the baffle slide plate 5. At the same time, the card block 33 drives the pin 35 to be inserted into the pin hole 42 through the transmission rope 37, which can lock the fog-permeable mirror frame 4 or the baffle 6 at the same time, further improving the stability of use.
