Description
Technical field
The utility model belongs to technical field of video monitoring, especially a kind of limit structure that regulates video monitoring equipment optical axis angle.
Background technique
Video monitoring is the important component part of safety and protection system, and it is the combination system that a kind of prevention ability is stronger.Video monitoring is directly perceived with it, accurately, in time and the information content abundant and be widely used in many occasions.In recent years, along with computer, network and image are processed, the develop rapidly of transmission technology, Video Supervision Technique has also had significant progress.
As The Cloud Terrace, the spherical camera of video monitoring front end equipment, camera unit and additional lighting unit are installed conventionally, for the optical axis of camera unit and additional lighting unit is parallel to each other, often need in The Cloud Terrace or spherical camera, design optical axis adjusting part.
Traditional optical axis adjusting part is generally controlled the maximum magnitude of its motion by control circuit and limit switch, by limit switch, feed back to control circuit signal, its objective is and avoids optical axis adjusting part to exceed the problem that adjustment range causes its structural failure.Because limit switch and circuit board are electronic component, there is certain working life, thereby improved the maintenance probability of video monitoring equipment, and adopt above-mentioned limit structure to increase the complexity of control circuit, also increased cost simultaneously.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of limit structure of simple in structure, flexible and convenient to use, adjusting video monitoring equipment optical axis angle that cost is low is provided.
Scheme of the present utility model is achieved in that
A kind of limit structure that regulates video monitoring equipment optical axis angle, comprise motor, screw rod, flip sleeve, regulator plate, fixed plate and spring, described motor is arranged on electric machine support, the upper end of the screw rod that the output shaft vertical connecting of this motor arranges, the lower end of this screw rod coaxially connects positioning seat, the middle part coaxial threaded of described screw rod connects flip sleeve, the screw rod outer rim coaxial package spring of this flip sleeve below, underpart and the positioning seat of this spring link together, described flip sleeve one side hinge load connects one end of regulator plate, the other end hinge load of this regulator plate connects fixed plate.
And the below, regulator plate end that is positioned at flip sleeve one end vertically connects extension spring.
And the screw coaxial between described flip sleeve and spring is installed pad.
And the screw thread upper and lower end portion that described screw coaxial is shaped with is shaped with respectively chamfering.
Advantage of the present utility model and good effect are:
This limit structure adopts the mode of mechanical position limitation, and when operator's misoperation makes flip sleeve surpass regulation range, flip sleeve dallies on screw rod, define flip sleeve regulation range, thereby avoid damaging this structure.The utility model is simple in structure, design science is reasonable, with low cost and not fragile.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that flip sleeve of the present utility model screws out screw flight downwards and is partly subject to spacing structural representation;
Fig. 3 is that flip sleeve of the present utility model upwards screws out screw flight and is partly subject to spacing structural representation.
Embodiment
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail.
A kind of limit structure that regulates video monitoring equipment optical axis angle, as shown in Figure 1, comprise motor 1, screw rod 3, flip sleeve 4, regulator plate 6, fixed plate 8 and spring 11, described motor is arranged on electric machine support 2, the upper end of the screw rod that the output shaft vertical connecting of this motor arranges, the lower end of this screw rod coaxially connects positioning seat 10, the middle part coaxial threaded of described screw rod connects flip sleeve 4, the screw rod outer rim coaxial package spring of this flip sleeve below, underpart and the positioning seat of this spring link together, described flip sleeve one side connects one end of regulator plate by the 5 hinge loads of flip sleeve hinge, the other end of this regulator plate is connected and fixed plate by fixed plate hinge 7, described positioning seat, fixed plate and electric machine support all link together with the housing (not shown) of this video monitoring equipment, the present embodiment is attached not shown.
In the present embodiment, the below, regulator plate end that is positioned at flip sleeve one end vertically connects one end of extension spring 9, and the other end of this extension spring is connected with housing.
In order to reduce the frictional force of spring and flip sleeve lower end surface, the screw coaxial between flip sleeve and spring is installed pad 12.
The screw thread upper and lower end portion that described screw coaxial is shaped with is shaped with respectively chamfering 13, and this chamfering plays leading role, makes flip sleeve be easy to screw in screw flight portion.
Working principle of the present utility model is:
One end of camera unit (not shown) and the load of housing hinge are connect, the other end is arranged on the regulator plate of this structure, when driven by motor screw rod is rotated counterclockwise referring to Fig. 2, flip sleeve moves down and drives regulator plate to rotate around fixed plate hinge, when flip sleeve screws out screw flight portion completely, flip sleeve Compress Spring will dally simultaneously on screw rod, and now flip sleeve no longer continues to move down, thereby effectively prevent because overload is by this structural failure; If need regulator plate to move up, control motor opposite spin, as shown in Figure 3, when flip sleeve screws out screw flight portion completely, flip sleeve will dally on screw rod, now control motor counterrotating again, thereby extension spring pulls regulator plate to pull flip sleeve to make it fast rotary, get back on screw flight.If operator continue misoperation, make driven by motor screw rod continue to rotate, flip sleeve dallies on screw rod, now flip sleeve no longer continue to move down prevent due to overload by structural failure.
This limit structure adopts the mode of mechanical position limitation, and when operator's misoperation makes flip sleeve surpass regulation range, flip sleeve dallies on screw rod, define flip sleeve regulation range, thereby avoid damaging this structure.The utility model is simple in structure, design science is reasonable, with low cost and not fragile.
It is emphasized that; embodiment described in the utility model is illustrative; rather than determinate; therefore the utility model comprises and is not limited to the embodiment described in embodiment; every other mode of executions that drawn according to the technical solution of the utility model by those skilled in the art, belong to the scope that the utility model is protected equally.
