Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to camera auxiliary device field, especially a camera is with air pressure dustproof ring. BACKGROUND
[0002] At present, the place such as mining working face, coal bunker upper and lower mouth in coal mine underground cannot reach the condition of no dust and no water mist pollution. Due to the underground environment factor, the lens at the above-mentioned position must be cleaned once every half an hour, which will inevitably affect the normal production of coal mine, and frequent climbing operation also increases the safety hazard. If the lens cannot be cleaned in time, the remote monitoring and operating personnel cannot accurately master the actual situation of the scene, which will bring greater safety hazard.
[0003] At present, there is still lack of reasonable solution to the problem. CONTENT OF UTILITY MODEL
[0004] The utility model discloses a kind of air pressure dustproof rings for camera, to overcome the deficiencies of prior art, provide a kind of air pressure dustproof rings for camera with simple structure, flexible assembly maintenance-free, and it is convenient to use.
[0005] The equipment includes air ring body, and a plurality of air holes are arranged on the inner surface of the air ring body;
[0006] Quick couplings are further arranged on the air ring;
[0007] The effect realized by this is that external gas source, that is, underground constant gas source, can be connected by quick coupling, that is, the air ring body can be inflated, and air is sprayed outward by the air hole, and based on the annular arrangement form, when the air ring is set on the front of lens, the effect of local air pressure blowing can be realized, and the situation that lens is fogged or dust is deposited can be avoided.
[0008] The air ring body is provided with an assembly body at the back. The effect realized by this is that the air ring is assembled in front of lens.
[0009] The utility model has the advantages that the utility model solves the safety problem caused by lens fogging or dust accumulation in the prior art, and realizes lens maintenance work without manual operation. It is especially suitable for environments such as underground environment with constant air pressure, dust raising and moisture. DRAWINGS

[0017] Referring to Figure 1 , Figure 2 The air pressure dustproof ring for the camera comprises an air ring body 1, and a plurality of air holes 11 are arranged on the inner surface of the air ring body 1.
[0018] The air ring is further provided with a quick connector 2.
[0019] The effect achieved thereby is that the air ring body 1 can be inflated by connecting an external air source, i.e. a commonly used air source in a well, and air is sprayed outwards from the air holes 11, and based on the annular arrangement form, when the air ring is arranged in front of the lens, the effect of local air pressure blowing can be achieved, and the lens can be prevented from fogging or dust deposition.
[0020] The air ring body 1 is provided with an assembly body 3 at the back. The effect achieved thereby is that the air ring is assembled in front of the lens.
[0021] In Example 1, referring to the accompanying drawings of the specification Figure 2 and Figure 3 The air holes 11 are densely arranged around the inner surface of the air ring body 1.
[0022] The effect achieved thereby is that the lens surface dust deposition can be sufficiently avoided, and the lens can be prevented from fogging.
[0023] In Example 2, the air ring body 1 is integrally injection molded from an elastic material.
[0024] The effect achieved thereby is that the device can flexibly adapt to the lens outer diameter size within the stretching range, and the applicability is more extensive.
[0025] Further, the air ring body 1 is made of rubber material, and the assembly body 3 made of rubber material is integrally connected at the back of the air ring body 1.
[0026] The assembly body 3 is an elastic ring structure, including a trumpet connecting section 31 and a cylindrical connecting section 32, which are directed towards the lens body 1.
[0027] The effect achieved by this is that the lens rear part is elastically wrapped by the assembly body 3, so that the device can be quickly assembled, and the lens body 1 can be limited in front of the lens based on the setting of the trumpet connecting section 31 and the cylindrical connecting section 32.
[0028] Preferably, after the device is assembled, the tail part is locked by a hoop, as shown in the accompanying drawings. Figure 4
[0029] In the embodiment 3, the lens body 1 is provided in multiple shapes and sizes.
[0030] The effect achieved by this is that it is suitable for lenses of different specifications.
