Monitoring camera
View Patent ↗A monitoring camera has a body ( 10 ), a focus ring ( 20 ), a lens ( 30 ) and an optional control cover assembly ( 50 ). The focus ring ( 20 ) has an inner flange with an inner threaded surface ( 24 ) and an outer threaded surface ( 23 ) to attach respectively to the lens ( 30 ) and the body ( 10 ). The structure allows the lens ( 30 ) to be focused over a broad range. Additionally, the control cover assembly ( 50 ) is attached to a side face of the body ( 10 ) to cover and protect multiple switches ( 16 ) on the body ( 10 ).
1. A monitoring camera comprising:
a body ( 10 ) having
a front end;
a side face;
a recess ( 11 ) defined in the front end; and
a lens mount ( 14 ) inside the recess ( 11 ) and having an inner threaded surface ( 141 );
a focus ring ( 20 ) being a disk, mounted rotatably inside the recess ( 11 ) and having
an outer edge;
a central hole;
an inner face;
an inner flange ( 22 ) formed on and protruding from the inner face around the central hole and having an inner threaded surface ( 24 ) and an outer threaded surface ( 23 ) to screw into the inner threaded surface ( 141 ) of the lens mount ( 14 ); and
an outer flange ( 26 ) formed on and protruding from the inner face around the outer edge; and
a lens ( 30 ) mounted in the focus ring ( 20 ) and having a threaded proximal end ( 32 ) screwed into the inner threaded surface ( 24 ) of the focus ring ( 20 ).
2. The monitoring camera as claimed in claim 1 , wherein the recess ( 11 ) has a top edge and a bottom edge; and
two cutouts ( 12 ) are defined respectively in the top edge and the bottom edge to allow the recess ( 11 ) communicating out of the body ( 10 ).
3. The monitoring camera as claimed in claim 1 , wherein the body ( 10 ) has multiple switches ( 16 ) mounted on the side face of the body ( 10 ) and a control cover assembly ( 50 ) mounted on the multiple switches ( 16 ) to protect the switches ( 16 ).
4. The monitoring camera as claimed in claim 3 , wherein the control cover assembly ( 50 ) comprises a cover bracket ( 40 ) and a cover ( 51 ) slidably mounted on the cover bracket ( 40 ).
5. The monitoring camera as claimed in claim 4 , wherein the cover bracket ( 40 ) being a plate has
a front end;
a rear end;
two sides;
a limiting block ( 42 ) attached to the front end;
a latch ( 43 ) formed on the rear end;
two rails ( 41 ) formed respectively at the two sides; and
multiple openings to correspond to the multiple switches ( 16 ) to access to the multiple switches ( 16 ); and
the cover ( 51 ) being a plate has
a front end;
a rear end;
two sides;
a transverse rib ( 53 ) formed near the front end to abut the latch ( 43 ) on the cover bracket ( 40 ); and
two hooked tracks ( 52 ) formed respectively at the two sides to engage the two rails ( 41 ) on the cover bracket ( 40 ).
