As shown in Figure 1 and Figure 2, the present embodiment proposes a kind of roof dome-type camera, including:Camera body
1;Shell is imaged, it includes installing plate 21 and cloche 22, installing plate 21 is used to be installed on roof, and camera body 1 is installed
At the bottom center of installing plate 21, cloche 22 is dome-type structure, and cloche 22 is fastened on installing plate 21 and video camera sheet
Body 1 is located between installing plate 21 and cloche 22;Grey structure 3 is scraped, it includes scraping grey body 31, mounting cylinder 32, mounting ring 33, auxiliary
Grey portion 34 and drive division 35 are scraped, grey body 31 is scraped including drivening piece 311 and scrapes grieshoch 312, drivening piece 311 is circular arc, band
Mounting ring 33 rotation of the one end of moving part 311 with being installed on the edge of installing plate 21 is connected, and the other end of drivening piece 311 is with being installed on
The mounting cylinder 32 for filling the side of plate 21 rotates connection, and drivening piece 311 is across cloche 22, and drivening piece 311 is on the face of cloche 22
It is provided with and scrapes grieshoch 312, scrapes grieshoch 312 and be made of elastomeric material, drivening piece 311 is made of iron;Auxiliary is scraped grey portion 34 and wrapped
Driven member 341 and permanent magnet 342 are included, driven member 341 and permanent magnet 342 are circular arc, the end of driven member 341 and peace
Fill in the rotation connection of plate 21, driven member 341 and permanent magnet 342 is installed, permanent magnet 342 is parallel with drivening piece 311, and drive division 35 is used
In the rotation of driving drivening piece 311;And control circuit, it collects loaded in installing plate 21, and control circuit is electrically connected with drive division 35
Connect.
In order to avoid when dismantling cloche 22 to overhaul camera body 1, drivening piece 311 hinders glass with grieshoch 312 is scraped
The dismounting of cover 22, as shown in Figure 1 and Figure 3, mounting ring 33 is made up of the first ring body 331 and the second ring body 332, the first ring body
331 are fixedly connected with installing plate 21, and the one end of the first ring body 331 rotates with the second ring body 332 and is connected, the other end of the first ring body 331
Snapped connection with the other end of the second ring body 332, the one end of drivening piece 311 is placed between the first ring body 331 and the second ring body 332, this
One end that design realizes drivening piece 311 can be dismantled, and the rotation for follow-up drivening piece 311 provides condition;Drivening piece 311 is another
One end is rotated with mounting cylinder 32 by a rotary shaft 324 and is connected, and the end that mounting cylinder 32 is not connected with rotary shaft 324 is fixed with rotation
Ring 321, swivel becket 321 is connected between two rotation matrixes 322, and two rotation matrixes 322 are connected on a rotation seat 323, are turned
Dynamic seat 323 is used to be installed on roof, and a rotation matrix 322 is extended with mandrel to another rotation matrix 322, and mandrel, which is passed through, to be rotated
Ring 321 and swivel becket 321 can be relative to matrix 322 be rotated and mandrel is rotated, in mandrel, swivel becket 321 and rotating base
Junction set it is limited turn component 4, without using external force act on limit turn the time limit of component 4 turn component 4 limitation swivel becket 321 turn
It is dynamic;Limit is acted on using external force turn the time limit of component 4 and turn component 4 and can discharge swivel becket 321, so that swivel becket 321 can be rotated, work as band
When moving part 311 is placed between the first ring body 331 and the second ring body 332, the effect of the first ring body 331 and the first ring body 331 is certain
It can be stabilized on work station, but need drivening piece 311 to maintain the position for deviateing cloche 22 when maintenance, then be
This demand is reached, then devises limit and turns component 4;Drive division 35 includes the first rotate gear 351, the second rotate gear 352, the
One bevel gear 353, the second bevel gear 354, rotary electric machine 355 and driving shell 356, rotary shaft 324 pass through the first rotate gear
351 and rotary shaft 324 fixed with the first rotate gear 351, driving shell 356 is embedded in roof, and rotary electric machine 355 is arranged at room
In top, the second rotate gear 352, the first bevel gear 353 and the second bevel gear 354 may be contained within driving shell 356, second turn
Moving gear 352 is connected with the rotation of the inwall of driving shell 356 and the second rotate gear 352 exposes driving shell 356, the second rotate gear
352 are pivotally connected to the center of the first bevel gear 353 centrally through connection, and the first bevel gear 353 is engaged with the second bevel gear 354, turn
The rotating shaft of dynamic motor 355 is penetrated to driving shell 356 to be fixed with the center of the second bevel gear 354, when the end of drivening piece 311 is installed on
Second rotate gear 352 is engaged with the first rotate gear 351 after between first ring body 331 and the second ring body 332, the first turning gear
The design of the rotate gear 352 of wheel 351 and second realizes the rotatable of drivening piece 311, and rotates energy when returning to work station
Enough realize driving of the drive division 35 to it.
As shown in figure 4, in order to which the simple and easy to use limit of design structure turns component 4, limit, which turns component 4, to be included:Catch bar
41st, promote cylinder 42, limit rotating disk 43 and limit to turn spring 44, open up limited on the rotation matrix 322 for being not fixed to mandrel 325
Turn chamber, rotary shaft 324 stretches to limit and turns intracavitary, and limit turns intracavitary and is provided with promotion cylinder 42 of the opening towards mandrel 325, unlocked
Have to offer on the rotation matrix 322 of mandrel 325 and turn the pilot hole that chamber is connected with limit, catch bar 41 passes through pilot hole and catch bar
41 relatively unrotatable matrixes 322 are rotated, and the center line of catch bar 41 point-blank, is pushed away with the center line of rotary shaft 324
Lever 41 is connected with promotion cylinder 42 positioned at the end that limit turns intracavitary, promotes cylinder 42 to be placed on outside rotary shaft 324, promotes cylinder 42 remote
End from catch bar 41 connects limited rotating disk 43, and limited turn hole is opened up on the end face for promoting cylinder 42 in swivel becket 321,
Groove is provided with limit turn hole inwall, turning intracavitary in limit is provided with the catch bar 41 that catch bar 41 turns spring 44 through limit, and limit turns
The one end of spring 44 is with promoting cylinder 42 to fix, and limit turns the other end of spring 44 and turn cavity wall with limit to fix, and promotion is being acted on without external force
During bar 41, limit rotating disk 43 is stretched in the presence of limit turns spring 44 engages in limit turn hole with groove;It is used to push away in outer masterpiece
During lever 41, the elastic force that limit can be overcome to turn spring 44 causes limit rotating disk 43 to depart from limit turn hole.
Finally illustrate, the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, although with reference to compared with
The present invention is described in detail good embodiment, it will be understood by those within the art that, can be to skill of the invention
Art scheme is modified or equivalent substitution, and without departing from the objective and scope of technical solution of the present invention, it all should cover at this
Among the right of invention.
