Abstract
The utility model discloses a protruding diaphragm used for regulating the lens of a video camera. The protruding diaphragm consists of a diaphragm subassembly, a waterproofing ring and glass pieces. The diaphragm subassembly is composed of a lens cap, a small glass plunger ring, a middle cylinder and a big glass plunger ring. The glass pieces include a small glass piece and a big glass piece which are respectively arranged at two sides of the middle cylinder. The small glass piece and the waterproofing ring are installed in the lens cap and are fixed through the small glass plunger ring. The waterproofing ring is arranged between the middle cylinder and the big glass piece, and the big glass piece and the waterproofing ring are fixed on the middle cylinder through the big glass plunger ring. The lens cap is moveably connected with the middle cylinder. The protruding diaphragm used for regulating the lens of the video camera has the advantages that the lens cap can be dismantled without opening the shell of the video camera, so the lens can be regulated or replaced conveniently. Furthermore, since the lens cap can be dismantled, unstable substances volatilized from the shell of the video camera can be released in the ageing process in a factory, thus reducing atomization phenomena caused by heat from the core of the video camera.
Description
Technical field
The utility model relates to video camera accessory field, relates in particular to a kind of raised type that camera lens regulates circle that is in the light that is used for.
Background technology
Normally used infrared night vision video camera all faces two hang-ups: the one, and the reflective phenomenon that the light that infrared lamp sends is caused by housing or glass-reflected, the 2nd, the heating of inner body during owing to movement work, cause the unstable earnest volatilization of video camera inner body and attached on glass, thereby make the surface of glass produce atomizating phenomenon.These two kinds of problems have a strong impact on the serviceability of video camera.
The formula of the at present normally used circle that is in the light stretching in all the being circle that is in the light, rear lens is finished in the complete machine assembling, the circle that is in the light all is sealed in cloche and casing inside with infrared lamp, mainly be to be stretched into by the circle that is in the light to solve the infrared reflecting phenomenon under the lamp plate, circle then can't be regulated camera lens under the state of not tearing machine open after the machine assembling is finished but it is in the light.And video camera because vibrations may cause camera lens to produce displacement, makes the image blur of video camera in the process of long-distance transport.And in installation process, want it is carried out camera adjusting, its workload is big and need specific purpose tool just can open casing, and is extremely inconvenient.
The utility model content
The purpose of this utility model be to provide a kind of can be under the situation of not opening casing, can easy adjusting or the video camera raised type of the changing camera lens circle that is in the light.
For achieving the above object, the technical solution of the utility model is:
A kind of raised type that camera lens regulates circle that is in the light that is used for is made up of the coil assembly that is in the light, water proof ring and glass, and the described coil assembly that is in the light comprises lens cap, little glass trim ring, middle and glass trim ring greatly; Described glass comprises big glass and little glass; Tube both sides during big glass and little glass lay respectively at, little glass and water proof ring are installed in the lens cap and by little glass trim ring and fix; Be provided with water proof ring between middle tube and big glass, big glass and water proof ring are fixed on the middle tube by big glass trim ring; Lens cap and middle tube flexibly connect.
Described lens cap is a hollow cylindrical, have internal thread, middle tube is provided with baffle plate, and plate washer both sides and little glass trim ring are respectively equipped with external thread, the external thread of little glass trim ring and middle tube one side matches with the lens cap internal thread, and the external thread of middle tube opposite side matches with the internal thread of big glass trim ring.
Raised type that video camera the regulates circle that is in the light that is used for described in the utility model, when being installed on the video camera, lens cap protrudes in the video camera casing, can be under the situation of not opening the video camera casing in installation, test process, lens cap is taken off, thus easy adjusting or replacing camera lens; Because lens cap can take off, can in factory's burn-in test process, discharge the unstable material that volatilizes in the video camera casing in addition, alleviate the atomizating phenomenon that causes after the movement heating.
