In actual use, the inflation component can be configured with one or more. When there is only one, it can be connected to the first connecting pipe 6 that needs to be inflated through a quick-release connector. The piston 5 slides upward away from the base 1 under the action of the inflation component and the control valve 7, and the sliding distance can be controlled by the amount.
[0030] In this embodiment, by setting the steel casing 3, support rod 4, piston 5 and inflation assembly, the height and levelness of the grid structure can be safely and quickly adjusted to prevent deformation or even fracture of the grid structure due to tilting.
[0031] In the present invention, preferably, Figure 1 、 Figure 3 As shown, a stop ring 8 is fixedly installed in the steel casing 3 . The stop ring 8 is located at one end close to the top of the steel casing 3 . The inner diameter of the stop ring 8 is smaller than the diameter of the piston 5 .
[0032] In this embodiment, the stop ring 8 is provided to limit the movement of the piston 5 and prevent it from sliding out of the steel casing 3 .
[0033] In the present invention, preferably, Figure 1 and Figure 2 As shown, a laser emitter 9 and a laser receiver 10 are respectively installed on the outer surface of the steel casing 3, and the laser emitter 9 and the laser receiver 10 are both placed horizontally. The laser receiver 10 is provided with a control switch connected to the inflation component. When the laser emitted by the laser emitter 9 contacts the adjacent laser receiver 10, the control switch is disconnected and the inflation component does not work.
