The back face of the lens, either side of upper-lower and either side of left-right are each provided with a cardan axle seat, and the cardan axle seat is connected with the center cardan axle, the first cardan axle and the second cardan axle; the whole cost of the view finder can be cut down, and the purpose of quick-speed framing can be achieved.

Description

Image-taking device

Technical field

The utility model relates to the image-taking device of video camera, refers to especially a kind ofly can significantly reduce the whole cost of image-taking device, and reaches the image-taking device of finding a view fast.

Background technology

Because fast development of society, unban population density is constantly soaring, the crime ratio is also upwards soaring thereupon, each businessman, resident family all might become next ruffian's target, the dark lane of many side streets has become the dead angle of public security relatively, for guaranteeing the safety of people's lives and properties, we are not difficult to find in the streets and lanes or each hotel owner, bank, building etc. are provided with monitor, except the criminal intent that can deter the ruffian, more offender's crime scene can be shot with video-corder, for the police provide the investigation of handling a case clue in the future.

General known monitor all is adjustable, promptly at monitor bottom installing one universal pedestal, and the price of this kind monitor is not only expensive, and the volume massiveness, after use a period of time, can make universal pedestal wearing and tearing because of often rotating, certainly lead to maintenance and maintenance cost, and, cause the speed of rotation too slow because of monitor itself is too heavy, such physical construction can make the person who is ambitious or tenacious of purpose avoid finding a view of camera lens easily, causes a big dead angle of public security.

Summary of the invention

Fundamental purpose of the present utility model is to provide a kind of and can significantly reduces the whole cost of image-taking device, and the image-taking device that can find a view fast.

A kind of image-taking device is provided with an adjustable mirror body before the camera lens of a fixed image-taking device, this mirror body back side is provided with the control pedestal of this mirror somascope face reflection angle of control; It is characterized in that: this control pedestal is provided with at least:

One sway brace stands and is located at the control base bottom, and its top is provided with a center universal shaft, and this center universal shaft correspondence is hubbed on the central point at the mirror body back side;

One vertical control device, its top is provided with a motor, a swingle is established in this motor below, this swingle one side and first universal shaft, one end articulate, this first universal shaft other end correspondence is hubbed at the central point of a left side, the mirror body back side/right both sides either side, in addition, be provided with a sensing apparatus in the swingle bottom;

One horizontal control device, the one side is provided with a motor, this motor one side is established a swingle, universal axle bed on this swingle periphery and an end of second universal shaft articulate, the other end correspondence of second universal shaft is hubbed on the mirror body back side/central point of the arbitrary end in following two ends, in addition, the outer end of this swingle is provided with a sensing apparatus.

Above-mentioned sensing apparatus can be any among variable resistor, microswitch or the scrambler.

Center, an above-mentioned mirror body back side, on/following arbitrary end and a left side/right either side respectively be provided with a universal axle bed, respectively with the control pedestal on sway brace the center universal shaft, vertically control device first universal shaft, laterally second universal shaft of control device articulates.

The catoptron of above-mentioned mirror body can be any in level crossing, convex mirror or the concave mirror.

Advantage of the present utility model is: this image-taking device not only can save the universal pedestal of bottom, more can avoid the former universal pedestal maintenance cost that frequent rotation wearing and tearing are produced because of image-taking device heavily reaches; Because the applied mirror body weight of the utility model is light, the whole cost of image-taking device can be significantly reduced again, and the purpose of finding a view fast can be realized.

Embodiment

Shown in Fig. 1-3, a kind of image-taking device is provided with an adjustable mirror body 2 before the camera lens of a fixed image-taking device 1, and these mirror body 2 back sides are provided with the control pedestal 3 of these mirror body 2 specular angles of control; This control pedestal 3 is provided with at least:

One sway brace 31, upright control pedestal 3 bottoms of being located at, its top is provided with a center universal shaft 311, and these center universal shaft 311 correspondences are hubbed on the central point at mirror body 2 back sides;

One vertical control device 32, its top is provided with a motor 321, a swingle 322 is established in these motor 321 belows, these swingle 322 1 sides and first universal shaft, 323 1 ends articulate, these first universal shaft, 323 other end correspondences are hubbed at the central point of a left side, mirror body 2 back side/right both sides either side, in addition, be provided with a sensing apparatus 324 in swingle 322 bottoms, but the rotary state of sensing rotation bar 322, can calculate the swing amount of X-axis according to the size that state value changes, for computer control provides data along mirror body 2 back side central points;

One horizontal control device 33, one side is provided with a motor 331, these motor 331 1 sides are established a swingle 332, universal axle bed on these swingle 332 peripheries and an end of second universal shaft 333 articulate, the other end correspondence of second universal shaft 333 is hubbed on mirror body 2 back sides/central point of the arbitrary end in following two ends, in addition, the outer end of this swingle 332 is provided with a sensing apparatus 334, can sense the rotary state of swingle 332, can calculate the oscillating quantity that Y-axis leans forward, swings back along mirror body 2 back side central points according to the size that state value changes, for computer control provides data;

Above-mentioned sensing apparatus 324,334 can be any among variable resistor, microswitch or the scrambler.

One mirror body 2, center, the back side, on/following arbitrary end and a left side/right either side respectively be provided with a universal axle bed 21,22,23, respectively with control pedestal 3 on sway brace 31 center universal shaft 311, vertically control device 32 first universal shaft 323, laterally second universal shaft 333 of control device 33 articulates; Moreover this mirror body 2 can need according to the angle of catoptron, can be in level crossing, convex mirror or the concave mirror any.

From the above, this mirror body 2 can be under the control of micro computer, periodic its reflection angle of adjusting, and can adjust the reflection angle of mirror body 2 by vertical control device 32 and horizontal control device 33, and in real time the rotary state value that is sensed is transferred to micro computer by each sensing apparatus 324,334, after micro computer contrasts as calculated, X, Y-axis oscillating quantity can be accurately regulated and control, thereby the angle coverage of mirror body 2 can be accurately controlled along mirror body 2 back side central points.

The above only is preferred embodiment of the present utility model; be not to limit practical range of the present utility model with this; such as those who are familiar with this art; use principle of the present utility model and technical characterictic; various changes and the decoration done all should be covered by within the category that these claims protect.
