[0003] The existing community security system will install cameras at various locations on the exterior walls of residential buildings to form a monitoring device with multi-directional coverage. During construction, holes are first drilled on the exterior wall, and then the bracket is fixed to the exterior wall with expansion bolts, and finally the camera is installed on the bracket.

[0004] The installation angle of existing cameras is usually rotated in the horizontal and vertical directions to achieve the rotation of the camera to a suitable angle. However, after the camera angle is adjusted, the knob usually needs to be tightened to achieve a fixed angle. After debugging and installation, the knob used to lock the vertical rotation of the camera is prone to loosening during long-term use, resulting in deviation in the camera angle.

The lower surface of the turntable 4 is provided with a hemispherical protrusion 42, and the plug-in bracket 2 is provided with a spherical groove 24 corresponding to the hemispherical protrusion 42, and the spherical groove 24 is connected to the second through hole 23. The elastic fixing mechanism 5 includes a telescopic rod 51 that passes through the second through hole 23 and is threadedly connected to the center of the lower surface of the turntable 4, a lifting head 52 provided at the lower end of the telescopic rod 51, and a second spring 53 that is sleeved on the telescopic rod 51 and has its two ends pressed tightly between the plug-in bracket 2 and the lifting head 52. At the same time, an annular groove 521 is provided on the circumference of the lifting head 52.

[0030] like Figure 2 , Figure 3 and Figure 5 As shown, the plug-in bracket 2 is provided with two first through holes 21 near the fixed bracket 1, and the fixed bracket 1 is provided with a locking hole 11 corresponding to the first through holes 21. The locking mechanism 3 includes a locking rod 31 in a U shape with both ends embedded in the first through holes 21, and two first springs 32 arranged at the ends of the locking rod 31 and driving the locking rod 31 to be embedded in the locking hole 11. The height of the locking rod 31 is the same as the height of the annular groove 521, and at the same time, the two ends of the locking rod 31 are respectively hingedly provided with a limiting column 33 which is telescopically arranged in the first through hole 21 and is used to be embedded in the locking hole 11. The end surface of the plug-in bracket 2 close to the fixed bracket 1 is provided with a mounting groove 25 which is connected with the first through hole 21, and the circumference of the limiting column 33 is provided with an annular limiting plate 34, and the two ends of the first spring 32 are pressed between the annular limiting plate 34 and the groove bottom of the mounting groove 25.

[0033] When the locking mechanism 3 is in use, the first spring 32 drives the end of the locking rod 31 to be embedded in the locking hole 11, so that the end of the locking rod 31 is located at the first through hole 21 and the locking hole 11, so as to lock and fix the plug-in bracket 2. The limiting groove 41 on the turntable 4 and the limiting strip 22 on the plug-in bracket 2, so that when the limiting groove 41 and the limiting strip 22 cooperate, the turntable 4 can be limited to be loose; at the same time, when the angle of the turntable 4 needs to be adjusted, the limiting groove 41 of the turntable 4 and the limiting strip 22 of the plug-in bracket 2 are separated by pressing the lifting head 52 upward and overcoming the elastic force of the second spring 53, so that the angle of the turntable 4 can be adjusted, thereby adjusting the angle of the camera 9 in the horizontal direction. The hemispherical protrusion 42 on the lower surface of the turntable 4 and the spherical groove 24 of the plug-in bracket 2 match, which can improve the matching stability between the turntable 4 and the plug-in bracket 2.

[0034] When the limiting column 33 is completely embedded in the locking hole 11, the middle part of the locking rod 31 is embedded in the annular groove 521 of the lifting head 52 and one end of the locking rod 31 connected to the limiting column 33 is telescopically arranged in the first through hole 21, at this time, the limiting column 33 can be vertically limited to avoid vibration of the turntable 4 and the telescopic rod 51 in windy weather; when the elastic force of the first spring 32 is overcome to make the limiting column 33 disengage from the locking hole 11, the end of the locking rod 31 connected to the limiting column 33 passes through the first through hole 21 and can be separated from the annular groove 521 of the lifting head 52 during the downward rotation process, which does not interfere with the use of the elastic fixing mechanism 5. The two sides of the part of the plug-in bracket 2 used for plugging into the fixed bracket 1 are provided with metal springs 10 for pressing against the fixed bracket 1, thereby improving the installation stability of the plug-in bracket 2.
