Description

A kind of image pick-up device installing rack

Affiliated technical field

The utility model belongs to the installing rack of the accessory of electronic surveillance equipment, particularly a kind of image pick-up device.

Background technology

The present electronic surveillance equipment that generally uses, as the surveillance in operation places such as the monitoring probe at video doorbell, traffic road junction, bank, market, station, harbour or the like, its equipment constitutes and mainly contains image pick-up device, display etc.Wherein image pick-up device generally by housing with and on camera lens, photoinduction element, circuit etc. form, its major product roughly has three types: a kind of is the image pick-up device that is adapted to daytime and has the workplace under the light environment to use, and generally is fixed with a filter between its camera lens and the photoinduction element; Another kind is the image pick-up device that is applied to night and does not have the workplace under the light environment to use, and is provided with infrared illumination source in the camera lens front, does not have filter between camera lens and the photoinduction element.The third then is the applicant's No. 012354872 a disclosed technical scheme of Chinese patent " a kind of image pick-up device ", its structure is: with optical filter device one movably on the framework, on the framework the filter position roughly the symmetry the position on device one water white transparency sheet is arranged, do to move driving by electric driving element and framework and cooperate, to realize that filter and water white transparency sheet can mutual alternative in the position at camera lens rear.When image pick-up device at night or do not have under the environment of light, infrared ray can see through the water white transparency sheet and be accepted by photoinduction element, when image pick-up device by day or have under the environment of light, light mating plate and unwanted light of elimination and radiation after filtration, accepted by photoinduction element, the image pick-up device of this technical scheme can adapt to the occasion that does not have light night, also can adapt to daytime or the occasion of light is arranged, and the popularization and application scope is wide.But the image pick-up device product of so preceding two kinds of structure types will lose market, becomes superseded overstocked commodities.

Summary of the invention

In order to make good use of the existing product resource, the utility model provides a kind of simple in structure, practical image pick-up device installing rack, the existing image pick-up device device that inside is not had a filter thereon, no matter daytime and the occasion that light is arranged, still night or do not have under the environment of light image pick-up device to work, its price and technical difficulty are not high.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of image pick-up device installing rack, it is characterized in that: comprise being used to install the space of placing image pick-up device in support body and the support body, the same direction in the place ahead of support body the place ahead and image pick-up device camera lens, the support body of image pick-up device camera lens anterior position is provided with a filter that is slidingly matched with the support body work, also is provided with an electric drive that cooperates with the driving of filter do on the support body.The sliding matching structure of described filter and support body can be that the hole on the filter is engaged in the slide bar of support body or the first-class form of chute that filter is engaged in support body; Described electric drive can be motor or electromagnetic attraction coil etc.; It can be type of belt drive such as rack-and-pinion, linkage, band transmission that motor cooperates with the driving of filter; The electromagnetic attraction coil cooperates and can cooperate with coil by an iron core that is connected with filter with the driving of filter; Described filter can be for glass sheet, also can be plastic sheet etc.; The utility model can also be realized automatic control by travel switch, light-sensitive device and control circuit.

Good effect of the present utility model is: under the situation of the internal structure that need not change image pick-up device, the support body of an installation image pick-up device is set, filter that can move and the electric drive that drives filter are housed on the support body, realize moving flexibly of filter, when image pick-up device at night or do not have under the environment of light, make filter leave camera lens by the control electric drive, photoinduction element is directly accepted the light of infrared light supply; When image pick-up device by day or have under the environment of light, before the control electric drive makes filter be in camera lens, light is mating plate and the unwanted light of elimination and the width of cloth are penetrated after filtration, accepted by photoinduction element, so realized that by this technical scheme the utility model can adapt to the occasion that does not have light night, the purpose that also can adapt to daytime or have the environment of light to work.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the side cross-sectional schematic of a kind of scheme of the utility model.

Fig. 2 is the A-A cutaway view of Fig. 1.

Among the figure 1, support body; 2, image pick-up device; 3, place the space of image pick-up device; 4, filter; 5, electric drive; 6, framework; 7, tooth bar; 8, gear; 9, slide bar; 10, the protective glass retaining is pulled; 11, bonnet; 12, travel switch.

Embodiment

With reference to Fig. 1～image pick-up device installing rack shown in Figure 2, feature is: structure comprises the space (3) that is used for installing placement image pick-up device (2) in support body (1) and the support body (1), the same direction in the place ahead of support body (1) the place ahead and image pick-up device (2) camera lens, the support body (1) of image pick-up device (2) camera lens anterior position is provided with a filter (4) that is slidingly matched with support body (1) work, also is provided with an electric drive (5) that cooperates with the driving of filter (4) do on the support body (1).In addition, filter (4) is mounted on the framework (6), and a tooth bar (7) is arranged on the framework (6), and electric drive (5) is a motor, fixes a gear (8) on motor (5) axle, and gear (8) constitutes driving with tooth bar (7) engagement and cooperates; The slide bar (9) that filter (4) is set in support body (1) by the hole on its framework (6) is gone up and is constituted and be slidingly matched; Be provided with the protective glass retaining at the position, front of support body (1) and pull (10), bonnet (11) is installed, to improve the dust reduction capability of installing rack in support body (1) rear end; Travel switch (12) is equipped with in the both sides of the inherent filter of support body (1) (4), so as to make filter (4) when moving into place motor (8) stop operating.
