Embodiment 1
Referring to Figure 1 to Figure 7, the embodiment of the present embodiment provides a kind of filter frame, including pedestal 103, bracket 101 and more
It is respectively arranged with sheet metal on a magnetic sheet 107, pedestal 103 and bracket 101, multiple magnetic sheets 107 are divided to for two groups of magnetic sheet groups 102, and two
Group magnetic sheet group 102 is respectively arranged between pedestal 103 and bracket 101, and the magnetic sheet 107 in every group of magnetic sheet group 102 is along pedestal 103
It is set gradually towards the direction of bracket 101, magnetic sheet 107 is connect with sheet metal magnetism.
The intermediate plate of existing filter frame mostly uses greatly screw connection, and this connection type installation and removal are got up all more numb
It is tired, it is especially in shooting process usually the usage quantity for being not fixed filter, the quantity of principle upper clip can be with filter
Quantity is corresponding, and existing filter frame is usually to install three pieces intermediate plate, but encounter special environment and requirement only uses two panels
When the case where filter, the problems such as directly being removed filter, will lead to light leakage, and if removing intermediate plate, after screw is backed out
It re-assemblies, this process takes a long time, and is a great inconvenience to natural views shooting, is easy to miss some slightly indulge i.e.
The scene to die.The bracket 101 of filter frame provided in this embodiment can be used to install filter, and filter is installed on bracket 101
Afterwards, bracket 101 is attached by magnetic sheet 107 with pedestal 103, magnetic sheet 107 respectively with the metal on pedestal 103 and bracket 101
Piece magnetism connection, increase or reduce sheet metal quantity can change the distance between bracket 101 and pedestal 103, using
