The thickness of backing plate 23 is highly unanimous with the clearance between bottom plate 21 and the fixed plate 50 to through set up backing plate 23 in the interval between bottom plate 21 and fixed plate 50, bottom plate 21 is unsettled when having avoided bottom plate 21 to be connected through screw 24 with fixed plate 50, thereby guarantees the stability of being connected of bottom plate 21 and fixed plate 50.
Referring to fig. 3 and 4, the fixing plate 50 is pre-buried to the construction surface 90, one side of the fixing plate 50 away from the bottom plate 21 is connected with the anchor bar 53, and one end of the anchor bar 53 away from the fixing plate 50 forms a hook structure, that is, the anchor bar 53 is a "J" type structure, and the anchor bar 53 with the "J" type structure can be anchored on the construction surface 90, so that the fixing plate 50 can be firmly fixed on the construction surface 90. Preferably, a plurality of anchor bars 53 are connected to a side of the fixing plate 50 away from the bottom plate 21, so as to further improve the stability of the anchoring construction surface 90 of the fixing plate 50.
Referring to fig. 1, one end of each second vertical rod 11 close to the construction surface 90 is provided with a universal wheel 40, and the universal wheel 40 is used for rolling contact with the construction surface 90, so that when the bottom plate 21 is separated from the fixing plate 50, the guardrail can be easily pulled or pushed, and the guardrail can be conveniently removed.
With continued reference to fig. 1, each second vertical rod 11 is provided with a movable plug 30, and the plug 30 is configured to be inserted into a pin hole pre-formed on the construction surface 90. Preferably, the latch 30 is movably disposed on the second vertical bar 11 in a vertical direction. Thereby, when the bottom plate 21 is fixedly connected to the fixing plate 50, the bolt 30 is inserted into the bolt hole preset on the construction surface 90, the stability of the guard rail can be further improved, and the protection safety can be improved. When the bottom plate 21 is separated from the fixing plate 50, the bolt 30 is pulled out from the jack, so that the guardrail can be removed, and the guardrail is convenient to operate and use.
