[0042] A dustproof cover plate 7 is fixedly connected to the outside of the buried tank 1 by bolts and is in clearance fit with the railing column body 6.

[0043] The automatic lifting safety guard rail can push the piston plate 3 to extrude the damping liquid filled in the pressure tank 2 when the electric push rod 4 is limited to extend and adjust, so that the transferred liquid is filled into the railing column body 6 to make it quickly extend and adjust, thereby realizing the quick lifting regulation effect of multiple railing column bodies 6. The railing column body 6 and the plugging pipe head 5 are assembled and installed, so that the quick replacement and maintenance operation of the railing column body 6 is facilitated.

[0044] With reference to Figure 2 and Figure 1 The automatic lifting safety guard rail disclosed in the embodiments of the present application comprises a butt joint screw cylinder 51, and a plugging ball 52 is elastically abutted in a limiting groove formed in the inside of the butt joint screw cylinder 51 by a spring member.

[0045] The automatic lifting safety guard rail can form the plugging pipe head 5 with the elastic plugging function by using the butt joint screw cylinder 51 and the plugging ball 52 under the composition of the spring member, so as to facilitate the storage of the liquid in the pressure tank 2.

[0046] With reference to Figure 3 and Figure 4 The railing column body 6 of the automatic lifting safety guard rail comprises a flexible telescopic air cylinder body 61, a press-fit ring frame 62 capable of abutting and limiting the plugging ball 52 is fixedly connected to one end of the air cylinder body 61, a lamp cylinder 63 is threadedly connected to one end of the air cylinder body 61, a light controller 64 is fixedly connected in the lamp cylinder 63, and a guide rod 65 is elastically slidably connected to one side of the light controller 64 by a spring member.

[0047] The automatic lifting safety guard, through the use of the balustrade column body 6 and the plugging pipe head 5 threaded installation, the pressing ring frame 62 installed at one end of the balustrade column body 6 pushes the elastic limiting plugging ball 52 in the plugging pipe head 5 to displace, thereby opening the plugging pipe head 5 passage, realizing flexible transfer adjustment between liquids, and when the balustrade column body 6 is limited to lift and adjust, the guide rod 65 can be elastically pressed, so that the displaced guide rod 65 presses the on-off switch in the light controller 64, realizes the automatic on-off of the warning light, ensures the eye-catching effect, and reduces power consumption.
