  Hereinafter, the present invention will be described in detail with reference to the best mode for carrying out the invention shown in the drawings.

  In the first preferred embodiment for carrying out the present invention shown in FIGS. 1 to 20, reference numeral 1 denotes a surveillance camera of the present invention in which a surveillance camera insertion hole 3 is formed in a ceiling plate 2 and attached to the site. The camera 1 can be inserted into the surveillance camera insertion hole 3 with a case body 5 having a lower end opening 4 and a ceiling plate at the outer periphery of the surveillance camera insertion hole 3 attached to the opening end of the case body 5. 2, a ring-shaped support plate 6 fixed to the ceiling plate 2, a lock mechanism 7 for fixing the ring-shaped support plate 6 to the ceiling plate 2, and the case body 5. A rotating cylinder 8 attached to the case body 5 so as to be able to swing a fixed amount in the horizontal direction, and a vertical swing without protruding from the ring-shaped support plate 6 to the rotating cylinder 8 can be performed. A camera support member 10 attached via a pair of rotating arms 9 The ring-shaped support that is detachably attached to the camera 13 connected to the terminals 11 and 12 fixed to the center of the camera support member 10 and the pair of rotating arms 9 and 9 of the camera support member 10. It is comprised with the cover body 15 in which the fan-shaped window 14 which covers the board 6 was formed.

  The case body 5 is formed in a cylindrical case body with a closed bottom surface in which terminal attachment portions 16 and 17 having terminals 11 and 12 attached to the bottom surface are formed, and lock piece storage recesses 18 and 18 are formed on the corresponding outer surfaces. 19 and a mounting piece 21 for fixing the ring-shaped support plate 6 by a plurality of screws 20 formed so as to protrude into the lock piece housing recesses 18 and 18 on the opening side of the case body 19. 21.

The ring-shaped support plate 6 has a ring-shaped support plate main body 22 having an outer diameter larger than the outer diameter of the case body 5 and an inner diameter smaller than the inner diameter of the case body 5, and an outer peripheral portion of the support plate main body 22. The positioning pieces 23, 23, 23, 23 that can be inserted into the case body 5, and the ring-shaped support plate main body 22 at a position located inside the inner diameter of the case body 5 The arc-shaped long hole 24 is formed.

  The lock mechanism 7 has a bolt inserted so as to protrude into the lock piece storage recesses 18 and 18 on the bottom surface side of the lock piece storage recesses 18 and 18 corresponding to the portion where the mounting pieces 21 and 21 are formed. Support pieces 26 and 26 having holes 25, bolt insertion holes 27 and 27 formed in the ring-shaped support plate 6 at portions corresponding to the bolt insertion holes 25 and 25 of the support pieces 26 and 26, and the bolts Insert holes 27, 27, bolts 28, 28 to be inserted into the bolt insertion holes 25, 25 of the support pieces 26, 26, and screw holes 29 to be screwed with the bolts 28, 28 are formed at the rear end portion. When not in use, the front end portion is supported by the mounting pieces 21, 21, and when the bolts 28, 28 are rotated in the tightening direction, the front end portion is composed of lock pieces 30, 30 positioned on the ceiling plate 2. .

  The rotating cylinder 8 is integrally formed with a rotating cylinder main body 31 that can be rotated without being spaced from an inner diameter portion of the ring-shaped support plate 6 and an outer peripheral portion near the upper portion of the rotating cylinder main body 31. The lever piece 32 positioned below the arc-shaped long hole 24 of the ring-shaped support plate 6 and the screw hole 33 formed in the lever piece 32 are screwed together, and the arc-shaped long hole 24 is at an arbitrary position. A positioning bolt 34 that can be fixed to the periphery, and a plurality of locking pieces 35, 35, 35 that are integrally formed on the upper end of the rotating cylinder body 31 and are locked to the ring-shaped support plate 6. And rotating arm support pieces 36 and 36 integrally formed on the corresponding inner wall surface of the rotating cylinder main body 31, and the position of the rotating cylinder 8 can be adjusted 25 degrees to the right and 25 degrees to the left.

  The camera support member 10 has a base plate 38 on which the camera 13 is detachably attached to a camera support tube 37 formed substantially in the center, and is expanded from a portion of the base plate 38 facing the camera support tube 37. A pair of pivot arms 9 and 9 projecting and pivotally supported at pivot arm support pieces 36 and 36 of the pivot cylinder 8 by pivot pins 39 and 39, and the pair of pivot arms 9 and 9 The lock bolt 40 prevents rotation of the rotation arm 9 screwed into one of the rotation arms 9, and the position from 0 degree to 45 degrees can be adjusted.

  The cover body 15 includes a cover main body 41 that can cover the ring-shaped support plate 6, a fan-shaped window 14 covered with a transparent material 42 formed on the cover main body 41, and the center of the fan-shaped window 14. The distal end portion sandwiched in an elastic state on the inner wall surface of the rotating cylinder 8 with the rotating arm support pieces 36, 36 of the rotating cylinder 8 arranged on the side of the section being bent is bent in a substantially square shape. The sandwiched pieces 44 and 44 are formed.

In the surveillance camera 1 having the above configuration, the surveillance camera insertion hole 3 is formed in the ceiling plate 2, the cover body 15 is removed, and the space between the ring-shaped support plate 6 and the lock pieces 30, 30 is larger than the thickness of the ceiling plate 2. In addition, the case body 5 is inserted in the state in which the lock piece storage recesses 18 and 18 are stored, the ring-shaped support plate 6 is brought into contact with the ceiling plate 2, and the bolts 28 and 28 of the lock mechanism 7 are rotated in the tightening direction. As a result, the distal ends of the lock pieces 30, 30 protrude outward from the lock piece storage recesses 18, 18 and protrude while rotating to a position where they abut against the wall surfaces of the lock piece storage recesses 18, 18.
By further rotating the bolts 28 and 28 in the tightening direction in this state, the lock pieces 30 and 30 are moved in the direction of the ring-shaped support plate 6, that is, the ceiling plate 2 is moved by the ring-shaped support plate 6 and the lock pieces 30 and 30. It can move in the direction of clamping and can be clamped and fixed.
Thereafter, the positioning bolt 34 screwed with the screw hole 33 of the lever piece 32 of the rotating cylinder 8 is loosened and slid on the arc-shaped elongated hole 24 to adjust the position in the horizontal direction. By tightening, the horizontal position can be fixed.
Further, after loosening the lock bolt 40 and rotating the camera support member 10 to adjust the position in the vertical direction, the camera support member 10 is fixed so that it cannot be rotated by tightening the lock bolt 40.
Next, when it is pushed into the pivot arm support pieces 36, 36 of the pivot cylinder 8 so as to be clamped by the clamp pieces 44, 44 of the cover body 15, the ring-shaped support plate 6 is covered. . At this time, the window 14 of the cover body 15 is located at a position that matches the direction of the camera 13, and even the small window 14 does not hinder the view of the camera 13.
Even after the surveillance camera 1 having the above-described configuration is attached to the ceiling board 2, it is possible to perform pan adjustment and tilt adjustment by rotating the rotating cylinder 8 and the camera support member 10 in the horizontal direction and the vertical direction.
