[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of the embodiments. It should be noted that the drawings are schematic and not to scale. For the sake of clarity and convenience, the relative sizes and proportions of the parts shown in the drawings are exaggerated or reduced in size, and any sizes are only illustrative and not restrictive.

[0021] See also Figure 1-Figure 5 A new type of safety passage includes multiple groups of pass frames 1 connected by foldable components and cover cloth 10 adapted to the outside of the pass frames 1. The multiple groups of pass frames 1 can be stretched and tightened through the foldable components.

[0022] The passage frame 1 includes two sets of symmetrical longitudinal bars 101, transverse bars 102 fixed to the top of the two sets of longitudinal bars 101, arcuate bars 103 fixed to the top of the transverse bars 102, and support bars 104 fixed between the transverse bars 102 and the arcuate bars 103. Self-locking universal wheels 2 are installed at the bottom ends of the longitudinal bars 101.

[0023] The curvature of the curved rod 103 matches the curvature of the top of the cover cloth 10, so that the cover cloth 10 fits more snugly when covered.

[0024] The foldable component includes a first connecting rod 3 and a second connecting rod 4. The two ends of the first connecting rod 3 are respectively rotatably mounted on the longitudinal rod 101 on the same side of the two adjacent groups of pass frames 1, and the two ends of the second connecting rod 4 are respectively rotatably mounted on the longitudinal rod 101 on the same side of the two adjacent groups of pass frames 1. The first connecting rod 3 and the second connecting rod 4 are cross-shaped, and the center positions of the first connecting rod 3 and the second connecting rod 4 are hinged by a third bolt 8.

[0025] The top ends of the first connecting rod 3 and the second connecting rod 4 are rotatably mounted on the longitudinal rod 101 through the first bolt 6, and the bottom ends of the first connecting rod 3 and the second connecting rod 4 are hinged through the second bolt 7, and the end of the second bolt 7 is connected to a safety ring 11 sleeved on the outside of the longitudinal rod 101, and a limit pin 12 passes horizontally through the longitudinal rod 101. When the multiple groups of pass frames 1 are in an elongated state, the safety ring 11 is in close physical contact with the limit pin 12.

[0026] When the plurality of passage frames 1 are in an elongated state, the plurality of longitudinal rods 101 on the same side are fixed with the same set of reinforcing rods 5, such as Figure 1 As shown, the reinforcement rod 5 is fixed to the multiple groups of longitudinal rods 101 by the fourth bolt 9. After removing the reinforcement rod 5, the pass frames 1 at both ends are pushed toward the middle, so that the multiple groups of pass frames 1 return to the tightened state, that is, the adjacent pass frames 1 are in a state of being close together. This state does not need to be illustrated separately, and those skilled in the art will also be able to clearly understand this structural state.

[0027] The cover cloth 10 is secured to the longitudinal rod 101 via ties. The passage frame 1 of this utility model utilizes galvanized steel pipes for welded connection, ensuring safety and reliability. The longitudinal rod 101, first connecting rod 3, and second connecting rod 4 are provided with mounting holes compatible with the first and second bolts 6 and 7. The longitudinal rod 101 also has a mounting hole compatible with the fourth bolt 9.

[0028] Working principle of this embodiment: When using this new safety passage, first, stretch the two ends of the pass frame 1 in opposite directions, so that the first connecting rod 3 and the second connecting rod 4 are in a largely crossed state. At this time, the safety ring 11 slides upward until it is in close physical contact with the limit pin 12. Then, the reinforcement rod 5 is fixed horizontally to the inner side of the longitudinal rod 101 by the fourth bolt 9, so that the multiple groups of pass frames 1 maintain a distance. The cover cloth 10 is covered on the pass frame 1 and tied and fixed to the longitudinal rod 101 by the lacing to complete the arrangement. When it needs to be moved, it can be dragged at will by the self-locking universal wheel 2. The self-locking universal wheel 2 is adjusted to the locked state to achieve fixed point fixation. After use, remove the cover cloth 10, remove the reinforcement rod 5, and push the two ends of the pass frame 1 toward the middle. At this time, the safety ring 11 slides downward, so that the multiple groups of pass frames 1 return to the tightened state. It is convenient for transportation and storage without taking up space. It is convenient and quick to install and disassemble.
