The invention relates to a parallel arc-shaped railing type restraint frame. The parallel arc-shaped railing type restraint frame consists of two groups, wherein each group consists of parallel arc-shaped railings, cross rods, push-and-pull rods, rollers and blocking plates, one end of each parallel arc-shaped railing is connected with a corresponding cross rod through shafts and is connected with the corresponding cross rod through a corresponding supporting rod, of which the two ends are provided with hookers, the push-and-pull rods and the cross rods are connected through sticking, the rollers are connected to the lower ends of the parallel arc-shaped railings, which are connected with the two ends of each cross rod, through shafts, and the blocking plates are respectively plugged in a plug slot in one side of each parallel arc-shaped railing. The parallel arc-shaped railing type restraint frame has the advantages that the structure is simple, the operation is convenient, the number of restraint at a time is large, the effect is good, the epidemic prevention rate is high, and the practicability is strong.
