Each guardrail comprises two columns of vertical bars 31, one row of cross bars 32, a plurality of guide wheels 33, a guardrail rope 34 and a guardrail rope tightening and adjusting mechanism 35. The lower end of each row of vertical rods 31 is pivoted with the base 2, and the two ends of the cross rod 32 are respectively pivoted with the upper ends of two rows of vertical rods 31. The guide wheels 33 are respectively arranged on the two rows of vertical bars 31; one end of the guardrail rope 34 is fixed on any one of the vertical rods 31, the other end of the guardrail rope 34 is connected with the guardrail rope tightening and adjusting mechanism 35, the guardrail rope 34 respectively bypasses the guide wheel 33 arranged on the left vertical rod and the guide wheel 33 arranged on the right vertical rod in the height direction in a left-right alternating manner, and a plurality of rows of transverse rope sections 341 extending transversely are formed below the cross rod 32.

The meaning of the above-mentioned "left and right alternate" is not limited to the guardrail rope 34 passing first around the guide wheel 33 of the left side vertical rod, and it may be that one end of the guardrail rope 34 is fixed to the left side vertical rod 31 of the guardrail 3a as shown in fig. 2, and then the guardrail rope 34 passes first around the two guide wheels 33 of the right side vertical rod and then passes downward around the two guide wheels 33 of the left side vertical rod, or that one end of the guardrail rope 34 is fixed to the right side vertical rod 31 of the guardrail 3b as shown in fig. 2, and then the guardrail rope 34 passes first around the guide wheel 33 of the left side vertical rod and then passes downward around the guide wheel 33 of the right side vertical rod.

In the present embodiment, the plurality of guide wheels 33 includes a plurality of guide wheel sets, and the plurality of guide wheel sets are respectively disposed on the left side vertical rod and the right side vertical rod in a left-right staggered manner in the height direction; each guide wheel set comprises at least one guide wheel, a plurality of guide wheels in each guide wheel set are arranged in a row along the height direction, and the bottom end of the upper guide wheel set is flush with the top end of the adjacent lower guide wheel set so that the transverse rope section 341 horizontally extends. Taking the left guardrail 3a shown in fig. 2 as an example, the left guardrail includes four guiding wheel sets, the right side montant is located to the first guiding wheel set, including two guiding wheels 33 arranged from top to bottom, left side montant and right side montant are located respectively to the second guiding wheel set and the third guiding wheel set, two guiding wheels 33 arranged from top to bottom are also included, the left side montant is located to the fourth guiding wheel set, only one guiding wheel 33 is included, and the guardrail rope 34 is tightened up the adjustment mechanism 35 with the guardrail rope after bypassing the fourth guiding wheel set and is connected.

In this embodiment, the guardrail cable 34 is a steel cable. The guardrail rope tightening and adjusting mechanism 35 is a locker, and the locker 35 is fixed in the outer box 1.

Each guardrail has an unfolded state and a folded state; when each guardrail is in an unfolded state, two rows of vertical bars 31, one row of transverse bars 32 and a plurality of rows of transverse rope sections 341 are arranged transversely and vertically, as shown in fig. 2; each guardrail is received in the outer box 1 in a folded state. The outer box 1 may have a rectangular hexahedral shape, and includes an outer box body 1a and a lid 1b, and when a pair of guardrails is received in the outer box body 1a, the lid 1b covers the outer box body.

When folded, each guardrail follows the parallelogram side-falling principle. When the cross bar 32 at the top of the guardrail is pushed or pulled, the vertical bar 31 is driven by the base rotating shaft to rotate and incline to rotate integrally in one direction, and a parallelogram area is formed in the whole operation process. To make full use of the available space, the

protective barriers

3a, 3b are folded crosswise in two directions, i.e. the left protective barrier 3a is tilted to the right and the right protective barrier 3b is tilted to the left, as shown in fig. 4.

Further, a first limit structure is arranged between the leftmost vertical rod of the pair of

guardrails

3a and 3b and the outer box 1, and the first limit structure is used for preventing the pair of

guardrails

3a and 3b from inclining leftwards when in the unfolded state; a second limit structure is provided between the rightmost vertical bar of the pair of

guardrails

3a, 3b and the outer box 1, and the second limit structure is used for preventing the pair of

guardrails

3a, 3b from toppling to the right side in the unfolded state. In this embodiment, the first limiting structure is composed of a first limiting block 41, and the first limiting block 41 is connected to the left inner wall of the outer box 1; the second limit structure is composed of a second limit block 42, and the second limit block 42 is connected with the right inner wall of the outer box 1.

Preferably, the collapsible barrier module apparatus of this embodiment further comprises one or more sets of locking mechanisms in one-to-one correspondence with the one or more pairs of barriers, the locking mechanisms being configured to lock the pair of barriers in the deployed state.
