Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the light barrier video camera that is provided with of the present embodiment comprises the shell 4 being provided with opaque housing 41 and translucent cover 42, is arranged on the camera lens 2 in shell 4 rotationally, and is arranged on the inner side of shell 4 or the light barrier 3 in outside.Wherein, relative to housing 41, camera lens 2, comparatively near translucent cover 42, enters camera lens to make light from translucent cover 42.Translucent cover 42 comprises the cylinder 422 be connected with housing 41 and the sphere 421 be connected with cylinder 422.At least part of light barrier 3 overlaps with the cylinder 422 region radial direction being positioned at camera lens 2 front.That is, at least part of light barrier 3 along cylinder 422 radial direction be projected in be positioned at camera lens 2 front cylinder 422 on.
Arrange by the way, as shown in Figure 2 (wherein dotted line represents light), can block by light barrier 3 light entering camera lens 2 from cylinder 422.Like this, when camera lens 2 is in little multiplying power (such as, camera lens 2 is in 0 ° of position field angle), substantially only from the light that the sphere 421 of translucent cover 42 enters, thus the imaging of camera lens 2 inside is overlapped substantially completely, and then make image comparatively clear.Certainly, light barrier 3 only can block the light that major part enters from cylinder 422, might not block all from the light that cylinder 422 enters.
As shown in Figure 3 and Figure 4, between camera lens 2 and shell 4, be also provided with inner cover 1, to pass through inner cover 1 support lens 2.The hemispherical nose 12 that inner cover 1 comprises cylindrical body 11 and is connected with cylindrical body 11.Wherein, camera lens 2 is roughly positioned at the position of hemispherical nose 12, and is in communication with the outside through sight vane.Housing 41 is arranged on the outside of cylindrical body 11, and translucent cover 42 is arranged on the outside of hemispherical nose 12.Light barrier 3, between inner cover 1 and housing 41, to block light barrier 3 by housing 41, thus improves the aesthetic property of video camera.The bending radian of light barrier 3 can be roughly the same with the bending radian of cylindrical body 11, so that mounting block tabula rasa 3.The material of light barrier 3 can be the transparent materials such as metal.The length of light barrier 3 is preferably, and after being fixed by light barrier 3, the two side ends of light barrier 3 is positioned at the both sides of sight vane.
Further, as shown in Figure 4, two sidewalls of light barrier 3 are respectively equipped with connecting portion.Web member is provided with in the outside of inner cover 1.Light barrier 3 is fixed by the web member 5 be arranged on connecting portion.And web member 5 is positioned at the below of camera lens 2, so that installation connecting element 5.In one example in which, web member 5 comprises and to be separately positioned on cylindrical body 11 and along the axially extended rotary screw rod 51 of cylindrical body 11 and guide rod 52.Wherein, rotary screw rod 51 is located in the hole of the first connecting portion 31 of light barrier 3, and guide rod 52 is located in the hole of the second connecting portion 32.
Arrange by the way, light barrier 3 can be driven to move towards close or away from translucent cover 42 direction by rotary screw rod 51 and guide rod 52.Like this, when needs block cylinder 422 by light barrier 3, drive light barrier 3 towards the lateral movement near diffuser by rotary screw rod 51.When not using light barrier 3, driving light barrier 3 towards the lateral movement away from diffuser by rotary screw rod 51, to block light barrier 3 by housing 41, thus improving the aesthetic property of video camera.And regulate light barrier 3 time save trouble and labor, the possibility of light barrier 3 run-off the straight in motion process can also be reduced by guide rod 52.
Preferably, rotary screw rod 51 is arranged on cylindrical body 11 by fixed head 53.In one example in which, fixed head 53 comprises the axially extended base plate along cylindrical body 11, and is separately positioned on the top of base plate and the side plate of bottom.Base plate is fixed on cylindrical body 11 by such as screw.For the side plate driving the motor 54 of rotary screw rod 51 to be arranged on base plate bottom.Rotary screw rod 51 wears base plate and is connected with motor 54.Setting like this, structure is simple, compact conformation, small volume.The action of motor 54 can pass through procedure auto-control, to enable the motion of light barrier 3 match with the field angle of camera lens 2, thus improves convenience in use.
In addition, the width of the first connecting portion 31 is less than the width of light barrier 3, and the first connecting portion 31 is near the bottom of light barrier 3, so that mounting plate 53.Second connecting portion 32 extends to the top of light barrier 3 from the bottom of light barrier 3, to improve precision when light barrier 3 moves.
Further, when light barrier 3 is in extreme higher position (when moving to final position towards hemispherical nose 12 side), (namely the upper end of light barrier 3 is no more than the joint face of the cylinder 422 of inner cover 1 and sphere 421, the upper end of light barrier 3 is positioned at below joint face), to reduce blocking of light barrier 3 pairs of light.When light barrier 3 is in extreme lower position (when moving to final position away from hemispherical nose 12 side), (namely the upper end of light barrier 3 is no more than the upper end of housing 41, the upper end of light barrier 3 is positioned at below the upper end of housing 41), to improve the aesthetic property of video camera.
Although be described the utility model with reference to preferred embodiment, when not departing from scope of the present utility model, various improvement can be carried out to it and parts wherein can be replaced with equivalent.Especially, only otherwise there is structural hazard, the every technical characteristic mentioned in each embodiment all can combine in any way.The utility model is not limited to specific embodiment disclosed in literary composition, but comprises all technical schemes fallen in the scope of claim.
