[0022] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0023] Reference Figure 1-Figure 6 As shown, the utility model provides a technical solution: a top-mounted structure of a surveillance camera, comprising a ceiling 1, both ends of the bottom of the ceiling 1 are fixedly connected with extension blocks 2, a limiting groove 3 is provided at the bottom of the extension block 2, a circular plate 4 is provided at the bottom of the ceiling 1, a camera body 5 is installed at the bottom of the circular plate 4, a power line 6 is installed on the surface of the camera body 5, circular holes 7 are provided on both sides of the circular plate 4, a limiting rod 8 is slidably connected to the inner wall of the circular hole 7, the surface of the limiting rod 8 is plugged into the inner wall of the limiting groove 3, one end of the limiting rod 8 is fixedly connected with a spring 9, and one end of the spring 9 is fixedly connected to the inner wall of the circular hole 7, The staff presses the limit rod 8 inward to retract it into the circular hole 7 and presses the spring 9 to store force. The staff places the circular plate 4 into the specified position at the bottom of the ceiling 1, so that the circular hole 7 is aligned with the limit groove 3. The limit rod 8 is then released to release the force generated by the spring 9, so that the spring 9 rebounds and pushes the limit rod 8 to move outward, so that the limit rod 8 is inserted into the inner wall of the limit groove 3, fixing the position of the circular plate 4, so that the circular plate 4 is suspended at the bottom of the ceiling 1, thereby realizing the rapid installation of the camera body 5 and the ceiling 1, and facilitating the staff to disassemble the device and remove the camera body 5 from the ceiling 1 for repair or replacement.

[0024] Reference Figure 3 and Figure 4 As shown, in the present embodiment: a first slide groove 10 is provided at the front end and the rear end of the inner wall of the circular hole 7, two sliders 11 are fixedly connected to the surface of the limit rod 8, and the surface of the slider 11 is slidably connected to the inner wall of the first slide groove 10. When the spring 9 drives the limit rod 8 to move, the sliding connection between the slider 11 and the first slide groove 10 is used to limit the moving trajectory of the limit rod 8, limit the maximum elastic force of the spring 9, limit the position of the limit rod 8 in the circular hole 7, and prevent the spring 9 from popping the limit rod 8 out of the inner wall of the circular hole 7, causing the component to detach, thereby improving the stability of the component operation.

[0025] Reference Figure 3 and Figure 4As shown, in the present embodiment: a through groove 12 is provided inside the limit rod 8, and a slide rod 13 is slidably connected to the inner wall of the through groove 12, and one end of the slide rod 13 is fixedly connected to the inner wall of the circular hole 7. The sliding connection between the slide rod 13 and the through groove 12 restricts the moving trajectory of the limit rod 8 in the circular hole 7 to prevent the limit rod 8 from tilting when moving, so that the limit rod 8 moves on the surface of the slide rod 13, and a horizontal movement trajectory is specified for the limit rod 8, so that the insertion of the limit rod 8 and the limit groove 3 is more precise.

[0026] Reference Figure 3 and Figure 4 As shown, in this embodiment: the slide rod 13 is placed on the inner wall of the spring 9, and the surface of the slide rod 13 is slidably connected to the inner wall of the spring 9. Through the sliding connection between the slide rod 13 and the spring 9, when the spring 9 is running, it moves closely on the surface of the slide rod 13, preventing the spring 9 from curling up when it shrinks and rebounds, causing entanglement and affecting the normal operation of the spring 9, thereby improving the stability of the component operation.

[0027] Reference Figure 1 and Figure 2 As shown, in the present embodiment: one end of the limit rod 8 is fixedly connected with a pull rod 14, and the surface of the pull rod 14 is slidably connected to the inner wall of the limit groove 3. Through the sliding connection between the pull rod 14 and the limit groove 3, when the limit rod 8 is in the limit groove 3, the staff can press the pull rod 14 to drive the limit rod 8 to enter the circular hole 7, which is convenient for the staff to control the position of the limit rod 8. At the same time, when the limit rod 8 is entered into the circular hole 7, the pull rod 14 can be inserted upward into the inner wall of the limit groove 3.

[0028] Reference Figure 1 and Figure 2 As shown, in this embodiment: an arc rod 15 is fixedly connected to one side of the extension block 2, and the surface of the arc rod 15 abuts against the surface of the power cord 6. Through the arrangement of the arc rod 15, the power cord 6 can pass through the top of the arc rod 15, or be wrapped around the surface of the arc rod 15, and the length of the power cord 6 is rolled up to prevent the power cord 6 from drooping and blocking the normal shooting angle of the camera body 5 after the device is installed.

[0029] Reference Figure 5 and Figure 6 As shown, in this implementation scheme: a cross groove 16 is provided at the front and rear ends of the top of the circular plate 4, and a cross plate 17 is fixedly connected to the front and rear ends of the bottom of the ceiling 1, and the inner wall of the cross groove 16 is plugged into the surface of the cross plate 17. By plugging the cross groove 16 and the cross plate 17, when the circular plate 4 is fixed to the bottom of the ceiling 1 by the limiting rod 8, the position of the circular plate 4 is more stable and not easy to shake, thereby improving the stability of the device for installing the camera body 5.

[0030] Working principle: the staff presses the limit rod 8 inward to retract it into the round hole 7 and presses the spring 9 to store force. The staff places the circular plate 4 into the specified position at the bottom of the ceiling 1, so that the round hole 7 is aligned with the limit slot 3, and then loosens the limit rod 8 to release the force generated by the spring 9, so that the spring 9 rebounds and pushes the limit rod 8 to move outward, so that the limit rod 8 is inserted into the inner wall of the limit slot 3, fixing the position of the circular plate 4, so that the circular plate 4 is suspended at the bottom of the ceiling 1, thereby realizing the rapid installation of the camera body 5 and the ceiling 1, and facilitating the staff to disassemble the device and remove the camera from the ceiling 1. The camera body 5 is repaired or replaced. When the spring 9 drives the limit rod 8 to move, the sliding connection between the slider 11 and the first slide groove 10 limits the movement trajectory of the limit rod 8, limits the maximum elastic force of the spring 9, limits the position of the limit rod 8 in the circular hole 7, prevents the spring 9 from popping the limit rod 8 out of the inner wall of the circular hole 7, and causes the component to be disengaged, thereby improving the stability of the component operation. The sliding connection between the slide bar 13 and the through groove 12 limits the movement trajectory of the limit rod 8 in the circular hole 7, prevents the limit rod 8 from tilting when moving, and causes the limit rod 8 to be tilted on the surface of the slide bar 13. The movement of the limit rod 8 specifies the horizontal movement trajectory of the limit rod 8, so that the insertion of the limit rod 8 and the limit groove 3 is more accurate. The sliding connection between the slide rod 13 and the spring 9 makes the spring 9 move closely on the surface of the slide rod 13 when it is running, so as to prevent the spring 9 from curling and winding when it shrinks and rebounds, affecting the normal operation of the spring 9, and improving the stability of the component operation. The sliding connection between the pull rod 14 and the limit groove 3 makes it possible for the staff to press the pull rod 14 to drive the limit rod 8 to enter the round hole 7 when the limit rod 8 is in the limit groove 3, so that the staff can control the position of the limit rod 8. When the rod 8 is received in the round hole 7, the pull rod 14 can be inserted upward into the inner wall of the limit groove 3. Through the arc rod 15, the power cord 6 can pass through the top of the arc rod 15 or be wrapped around the surface of the arc rod 15 to reel in the length of the power cord 6 to prevent the power cord 6 from drooping and blocking the normal shooting angle of the camera body 5 after the device is installed. Through the connection between the cross groove 16 and the cross plate 17, when the circular plate 4 is fixed to the bottom of the ceiling 1 by the limit rod 8, the position of the circular plate 4 is more stable and not easy to shake, thereby improving the stability of the device for installing the camera body 5.
