Embodiment 1
[0025] as attached figure 1 to attach Figure 5 Shown:
[0026] The invention provides a monitoring frame for security engineering, the structure of which includes a balance base 1, a support rod 2, and a fixer 3, the balance base 1 is embedded and installed directly under the support rod 2, and the support rod 2 is connected by welding Directly below the fixer 3, the fixer 3 is located above the balance base 1; the balance base 1 includes a connecting block 11, a first fixing block 12, a cardan shaft 13, a scanning board 14, and a fixed chassis 15. The connecting block 11 is embedded and connected to the upper end surface of the first fixed block 12, and the first fixed block 12 is embedded and connected to the upper end outer surface of the cardan shaft 13, and the cardan shaft 13 is located directly above the scanning board 14. The scanning board 14 is embedded and engaged with the inner upper end surface of the fixed chassis 15 , and the fixed chassis 15 is located direc...
Embodiment 2
[0033] as attached Figure 5 to attach Figure 7As shown: the telescopic column 513 includes a sliding groove 131, a sliding block 132, a positioning column 133, a spring 134, a second fixed block 135, and a movable column 136. The inner end surface of the sliding groove 131 is inlaid with the sliding block 132, The left and right sides of the sliding block 132 are embedded with the second fixed block 135, and the positioning column 133 is symmetrically installed on the left and right sides of the spring 134, and the spring 134 is located directly below the sliding block 132. The inner end surface of the block 135 is nested and connected with the positioning column 133, and the inner end surface of the movable column 136 is provided with a protrusion connected with the spring 134, which can form the effect of sliding up and down through the movable cooperation of the sliding block 132.
[0034] Wherein, the movable column 136 includes a flow hole 361, a one-way piston valve 3...
