The above-mentioned solution solves the problem that the fixing of the existing camera 1 on the fixing rod is troublesome, requires more time and manpower, and is inconvenient to operate.

[0024] For this specific embodiment, the fixing rod 104 is arranged above the mounting seat 103, the base 101 is arranged above the fixing rod 104, the camera 102 is fixedly connected to the base 101 and is located above the base 101, the mounting seat 103 is fixed to the ground, and the fixing rod 104 fixes and supports the camera 102 on the mounting seat 103. The camera 102 is used to monitor open flames. The camera 102 is already a prior art and will not be described in detail here.

[0025] First, the fixing seat 105 is fixedly connected to the fixing rod 104 and is located above the fixing rod 104. The fixing seat 105 has two cavities 113. The two groups of connecting components are connected to the base 101 and are respectively matched with the corresponding cavities 113. When the camera 102 is fixed above the fixing rod 104, the base 101 is fixed to the fixing seat 105 above the fixing rod 104 by using the two groups of connecting components, so that the camera 102 is fixed above the fixing rod 104.

[0026] The plug-in column 106 is fixedly connected to the base 101 and is located below the base 101 and is adapted to the cavity 113. The plug-in column 106 has a fixing hole 114. The slider 108 is slidably connected to the fixing seat 105 and is located in the cavity 113. The movable rod 109 is slidably connected to the fixing seat 105 and inserted into the cavity 113. The movable rod 109 is also fixedly connected to the slider 108. The two ends of the reset spring 110 are fixedly connected to the slider 108 and the fixing seat 105, respectively. The fixed arc block 107 is fixedly connected to the slider 108 and is located on the outer side wall of the slider 108. The fixed arc block 107 is also adapted to the fixing hole 114. When the camera 102 is fixed above the fixing rod 104, the two plug-in columns 106 under the base 101 are respectively inserted into the two cavities 113 of the fixing seat 105. The cavity 113 is L-shaped. The fixed arc block 107 has an arc surface. Each plug-in column 106 enters the cavity 113 to squeeze and push the fixed arc block 107. Then, The fixed arc block 107 pushes the slider 108 to squeeze the reset spring 110 in the cavity 113, and the movable rod 109 slides outward on the fixed seat 105. When the plug-in column 106 completely enters the cavity 113 of the fixed seat 105, the slider 108 is pushed to reset in the cavity 113 by the force of the reset spring 110. At this time, the fixed arc block 107 on the slider 108 enters the fixing hole 114 of the plug-in column 106, so that the base 101 is stable on the fixed seat 105. The camera 102 is installed above the fixing rod 104; when the camera 102 is disassembled, the movable rod 109 is pulled outward on the fixing seat 105, and the movable rod 109 drives the fixed arc block 107 to leave the fixing hole 114 of the plug-in column 106, and then the base 101 is separated from the fixing seat 105, and the plug-in column 106 leaves the cavity 113.

After the camera 102 is fixedly installed above the fixing rod 104, the protective cover 112 is used to screw on the outside of the fixing seat 105, and the protective cover 112 covers the movable rod 109 to prevent the movable rod 109 from being exposed.

[0029] When the camera 102 is fixed above the fixing rod 104, the two plug-in columns 106 under the base 101 are respectively inserted into the two cavities 113 of the fixing seat 105, the cavity 113 is L-shaped, and the fixed arc block 107 has an arc surface. Each plug-in column 106 enters the cavity 113, and the extrusion arc block 111 under the plug-in column 106 squeezes and pushes the fixed arc block 107, and then the fixed arc block 107 pushes the slider 108 in the cavity 113 to squeeze the reset spring 110, and the movable rod 109 slides outward on the fixing seat 105 together. When the plug-in column 106 completely enters the cavity 113 of the fixing seat 105, the slider is pushed by the force of the reset spring 110. The block 108 is reset in the cavity 113, and the fixed arc block 107 on the slider 108 enters the fixing hole 114 of the plug-in column 106, so that the base 101 is stabilized on the fixing seat 105, so that the camera 102 is installed above the fixing rod 104; when the camera 102 is disassembled, the movable rod 109 is pulled outward on the fixing seat 105, and the movable rod 109 drives the fixed arc block 107 to leave the fixing hole 114 of the plug-in column 106, and then the base 101 is separated from the fixing seat 105, and the plug-in column 106 leaves the cavity 113. In the above manner, the camera 102 can be quickly fixed on the fixing rod 104, which reduces the difficulty of work for personnel and is easy to operate.

[0030] Second embodiment

[0031] See also Figure 4 and Figure 5 ,in Figure 4 is a schematic diagram of the overall structure of the second embodiment, Figure 5 It is a cross-sectional view of the overall internal structure of the second embodiment.

The sealing gasket 206 is also sleeved on the outer wall of the fixing rod 104. By arranging the sealing gasket 206 at the movable part between the fixing rod 104 and the lifting cylinder 201, the sealing gasket 206 can increase the sealing effect of the movable part to prevent rainwater from entering the lifting cylinder 201.

[0036] When the height of the camera 102 is adjusted, the driving motor 203 in the lifting cylinder 201 is started, and the driving motor 203 controls the threaded rod 204 to rotate. Since the sleeve 202 is threadedly matched with the threaded rod 204, the sleeve 202 moves on the threaded rod 204, and the fixed rod 104 slides in the lifting cylinder 201. At the same time, the two limit blocks 205 on the outer wall of the fixed rod 104 slide in the lifting cylinder 201, and the limit blocks 205 guide the fixed rod 104. direction, so that the height of the camera 102 changes. After the height adjustment of the camera 102 is completed, the driving motor 203 is stopped from rotating in the lifting cylinder 201; wherein, by providing the sealing gasket 206 at the movable part between the fixing rod 104 and the lifting cylinder 201, the sealing gasket 206 can increase the sealing effect of the movable part to prevent rainwater from entering the lifting cylinder 201. Through the above method, the height of the camera 102 can be adjusted and can be used under different requirements, thereby increasing practicality.
