Description
Technical field
The present invention relates to network camera structure field, with light excluding shutter and realizes that this freely opens especially with respect to one kind
The camera lens of conjunction.
Background technology
Nowadays, video camera is just able to extensive use in multiple fields, and lens assembly is wherein more in video camera
Important component, by camera lens, the communication distance for the both sides that can further, camera lens may also function as monitoring, observe the purposes of specific environment.
But during the use of camera lens, camera lens is forgotten to need to close at any time after, or, user have been switched off camera lens but by
Camera lens is opened in Malware backstage, causes the privacy of user to leak.User think camera lens have been switched off but be substantially open
Under the scene opened, except the potential safety hazard of the privacy of leakage user be present, the wasting of resources can be also caused because of the unlatching of camera lens, because
This, conveniently realizes the opening and closing of camera lens thang-kng at any time, is the problem that the invention needs to solve.
Utility model content
The technical problems to be solved in the utility model is that, there is provided a kind of freely, easily to open, close camera lens
Thang-kng passage, so as to reach control video camera thang-kng system camera lens.
To solve above technical problem, the technical scheme that inventor takes is as follows：
Design and a kind of with light excluding shutter and realize the camera lens device of its free-open-close, including a camera lens, the camera lens
Provided with a daylighting passage, in addition to：
A motor is provided with the camera lens, the rotating shaft of the motor is provided with a little gear.
Also include a fan-shaped gear wheel, the gear wheel edge sets a sector rack, and the fan-shaped gear wheel passes through a gear shaft
It is articulated in camera lens, the affixed plectrum in one end of the rack, the plectrum is provided with one first connecting shaft, and described first
Connecting shaft can be in the first chute of arc slidably.
The daylighting passage of the camera lens is provided with a light excluding shutter, and one end of the light excluding shutter is provided with the second connecting shaft, and described
It is flexibly connected between two connecting shafts and the first connecting shaft by a connecting rod to reach.
The other end of the light excluding shutter sets a sliding bolt, and the sliding bolt can be in one second chute slidably, in sector
Under the drive of gear, light excluding shutter can be achieved and moved up and down in defined second chute, so as to realize the folding of light excluding shutter.
A kind of embodiment used is that the camera lens is similar to spherical camera lens, and the light excluding shutter and described second are slided
Groove is curved.
Benefit of the present utility model, it is by conducting, can facilitate real by electro-motor and by certain transmission device
The unlatching of existing shadow shield and closure, so as to optionally control camera lens thang-kng system.
Brief description of the drawings：
Fig. 1 is that the utility model carries light excluding shutter and realizes the schematic diagram of the camera lens device of its free-open-close, its
The state of middle light excluding shutter complete closure.
Fig. 2 is the schematic diagram of camera lens device of the present utility model, wherein light excluding shutter half-open position.
Fig. 3 is the daylighting access diagram of camera lens device of the present utility model, its corresponding light excluding shutter half-open position.
Fig. 4 is the daylighting access diagram of camera lens device of the present utility model, wherein the fully closed conjunction state of light excluding shutter.
Embodiment：
Now by enumerating specific embodiment, the utility model is further illustrated with light excluding shutter and realizes its free-open-close
Camera lens device：
As shown in Figure 1, it is a kind of to carry light excluding shutter and realize the camera lens device of its free-open-close, including a camera lens
1, the camera lens is provided with a daylighting passage, in addition to：
A motor 11 is provided with the camera lens 1, the rotating shaft of the motor 11 is provided with a little gear 12.
Also include a fan-shaped gear wheel 2, the gear wheel edge sets a sector rack 21, and the fan-shaped gear wheel passes through a gear
Axle 22 is articulated in camera lens 1, the affixed plectrum 23 in one end of the rack 21, and the plectrum 23 is provided with one first and connected
Spindle 61, first connecting shaft 61 can be in the first chutes 3 of arc slidably.
The daylighting passage of the camera lens is provided with a light excluding shutter 5, and one end of the light excluding shutter 5 is provided with the second connecting shaft 62, institute
State and be flexibly connected between the second connecting shaft 62 and the first connecting shaft 61 by a connecting rod 6 to reach.
The other end of the light excluding shutter 5 sets a sliding bolt 51, the sliding bolt 51 can in one second chute 4 slidably,
Under the drive of fan-shaped gear wheel 2, light excluding shutter can be achieved and moved up and down in defined second chute 4, so as to realize light excluding shutter 5
Folding.
A kind of embodiment used is that the camera lens 1 is similar to spherical camera lens, the light excluding shutter 5 and described second
Chute 4 is curved.
As shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4 in accompanying drawing, the motion of motor 11 is controlled by power switch, motor 11 is by power
It is transferred to fan-shaped gear wheel 2 and is further transferred to light excluding shutter 5, light excluding shutter 5 is slided in the second chute 4, hidden so as to reach
Optical gate closing, full closeding state, so as to control camera lens daylighting passage whether the effect of thang-kng.
