Limited block limiting slot in, be inserted with elastic ring in the central through hole that the middle part of movable plate has, the lateral wall of elastic ring is consolidated
It is scheduled on the madial wall for the central through hole that the middle part of movable plate has, the camera lens position of camera is nested in elastic ring.
The back side of the movable plate, which is at the upper and lower part of camera, has connecting rod, and connecting rod sleeve is in camera
The connecting hole of contiguous block that has of upper and lower part in, positioning bulb plunger is bolted with the madial wall of connecting hole, positions ball
The steel ball of headpin plug is nested in the shrinkage pool having on the side wall of connecting rod.
The top surface of the limiting slot of limited block on the upper backup pad is fixed with buffer spring, the lower end of upper buffer spring
It is pressed against the upper surface of movable plate, the bottom surface of the limiting slot of the limited block on lower supporting plate is fixed with lower buffer spring, lower buffering
The upper end of spring is pressed against on the lower face of movable plate.
The present invention protrusion effect be:
Compared with prior art, it is installed in wall, good concealment, meanwhile, its position can be met not with up and down adjustment
Same shooting requirement, effect are good.
Brief description of the drawings:
Fig. 1 is the structure diagram of the present invention;
Fig. 2 is the partial enlarged view of Fig. 1;
Fig. 3 is the partial sectional view of the middle main casing of the present invention.
Embodiment:
Embodiment, is shown in as shown in Figure 1 to Figure 3, a kind of concealed position-adjustable security protection camera, including wall 100, institute
Stating has installation groove 101 on the wall of wall 100, have connection line three-way hole 102, installation on the rear wall of installation groove 101
Housing 10 is nested in installation groove 101 and is fixed on the madial wall of installation groove 101;
Installation housing 10 includes middle main casing 11, and the top of middle main casing 11 is equipped with upper shell 12, middle main casing
11 middle part is equipped with drive screw 13, and the both ends of drive screw 13 are hinged on the upper backup pad 111 of middle main casing 11 and lower branch
On fagging 112, driving servomotor 113 is fixed with upper backup pad 111, the output shaft of driving servomotor 113 is splined shaft,
For splined shaft sleeve in the splined hole that the upper end of drive screw 13 has, the rear portion of camera 20 is fixed with two movable blocks 21,
Movable block 21 is screwed onto in drive screw 13, and the both sides of camera 20 have guide pad 22, have sliding slot 23 on guide pad 22, in
Between main casing 11 left and right two side walls on have be vertically directed block 114, be vertically directed 114 sleeve of block in sliding slot 23.
Further, the front portion of the lower plane of the front portion of the upper plane of the upper backup pad 111 and lower supporting plate 112 is equal
Limited block 14 is fixed with, is equipped with limited block 14 on limiting slot 15, limiting slot 15 and upper backup pad 111 or lower supporting plate 112
The slot 1 having is corresponding, and the spacing of the limited block 14 on upper backup pad 111 through slot 1 and is stretched into the top of movable plate 21
In groove 15, the lower part of movable plate 30 through slot 1 and is stretched into the limiting slot 15 of the limited block 14 on lower supporting plate 112, mobile
Elastic ring 31 is inserted with the central through hole that the middle part of plate 30 has, the lateral wall of elastic ring 31 is fixed on the middle part of movable plate 30
On the madial wall for the central through hole having, the camera lens position of camera 20 is nested in elastic ring 31.
Further, the back side of the movable plate 30, which is at the upper and lower part of camera 20, has connecting rod 32,
32 sleeve of connecting rod is in the connecting hole 241 for the contiguous block 24 that the upper and lower part of camera 20 has, the inner side of connecting hole 241
