[0009] 1. This utility model involves installing multiple vertical railings inside a circular fence. The circular fence and the vertical railings together form a fence. L-shaped side rails are fixed to the sides of the vertical railings. The L-shaped side rails are inserted into the side sleeves of the connecting plates, allowing the strip connecting plates to be installed on the sides of the circular fence and to rotate relative to each other. The strip connecting plates connect two adjacent circular fences on the left and right sides. Through the rotational connection structure between them, the maximum unfolding angle of the adjacent circular fences is 180 degrees horizontal, and the minimum rotation angle between them is zero degrees in a folded state. This connection structure ensures that multiple circular fences are always connected, facilitating on-site installation or storage and transportation at the construction site. The positioning connecting rod passes through the first positioning hole and connects to the V-shaped support plate, allowing the V-shaped support plate to be installed below the circular fence and to rotate below it. When the device is used at the construction site, rotating the V-shaped support plate makes it perpendicular to the circular fence. A set of V-shaped support plates supports the circular fence, ensuring the stability of the device during use and preventing tilting or falling during construction protection.

[0010] 2. In this utility model, the vertical sliding rod passes through the fourth positioning hole and connects to the horizontal connecting plate, and the column positioning rod passes through the second positioning hole and connects to the horizontal connecting plate. The vertical sliding rod can be moved up and down and rotated by pulling the handle above the ring fence. The positioning rod is inserted into the small diameter hole. Through the action of the column positioning rod and the positioning rod, the V-shaped support plate is kept perpendicular to the ring fence. When adjacent ring fences are folded together, the vertical sliding rod is pulled upward to disconnect the positioning rod from the small diameter hole. The V-shaped support plate is rotated to be horizontal with the ring fence. At this time, the vertical sliding rod is pushed downward to make the positioning anti-detachment plate pass through the large diameter hole. The V-shaped support plate is positioned by the column positioning rod, ensuring that the V-shaped support plate is retracted to the bottom of the ring fence. This prevents rotation during construction protection. This device is easy to open and fold during use and does not require on-site assembly. Attached Figure Description

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0018] Example 1:

[0019] A construction safety device includes a ring-shaped fence 01, vertical railings 02, L-shaped side rails 07, strip connecting plates 08, V-shaped support plates 10, positioning connecting rods 11, vertical sliding rods 14, positioning inserts 16, and handles 19. The vertical railings 02 are connected to the ring-shaped fence 01 at both ends. Multiple vertical railings 02 are evenly distributed within the ring-shaped fence 01. The ring-shaped fence 01 and the vertical railings 02 together form a fence. The L-shaped side rails 07 are connected to the ring-shaped fence 01, and two sets of L-shaped side rails 07 are symmetrically arranged at both ends of the ring-shaped fence 01. The strip connecting plate 08 has connecting plate side sleeves 09, and two sets of connecting plate side sleeves 09 are symmetrically arranged on the side of the strip connecting plate 08. The L-shaped side rails 07 are adapted to the connecting plate side sleeves 09. 7. Insert the connecting plate side sleeve 09. The L-shaped side rod 07 rotates within the connecting plate side sleeve 09. A set of ring fence rods 01 are symmetrically arranged on the side of the strip connecting plate 08. The strip connecting plate 08 is symmetrically arranged on both sides of the ring fence rod 01. The L-shaped side rod 07 is installed and fixed on the side of the vertical railing 02. The L-shaped side rod 07 is inserted into the connecting plate side sleeve 09, so that the strip connecting plate 08 is installed on the side of the ring fence rod 01 and the two can rotate relative to each other. The two adjacent ring fence rods 01 are connected by the strip connecting plate 08. The rotational connection structure between the two makes the maximum unfolding angle of the adjacent ring fence rods 01 horizontal 180 degrees and the minimum rotation angle between the two is zero degrees in a folded state. This connection structure keeps multiple ring fence rods 01 connected at all times, which is convenient for on-site installation or storage and transportation at the construction site.

[0020] Example 2:

[0021] The circular fence post 01 of this utility model has a first positioning hole 03 at its lower part. The positioning connecting rod 11 is adapted to the first positioning hole 03 and is inserted into the first positioning hole 03. The positioning connecting rod 11 rotates within the first positioning hole 03. The lower part of the positioning connecting rod 11 is connected to a V-shaped support plate 10. The positioning connecting rod 11 passes through the first positioning hole 03 and connects to the V-shaped support plate 10, so that the V-shaped support plate 10 is installed below the circular fence post 01 and can rotate below the circular fence post 01. When the device is used at the construction site, the V-shaped support plate 10 is rotated so that the V-shaped support plate 10 is perpendicular to the circular fence post 01. A set of V-shaped support plates 10 supports the circular fence post 01, ensuring the stability of the device during use and preventing tilting or falling during construction protection. The upper surface of the V-shaped support plate 10 is in contact with the lower surface of the circular fence post 01. A set of V-shaped support plates 10 is symmetrically arranged at the lower part of the circular fence post 01.

[0022] Example 3:

[0023] The circular fence post 01 of this utility model has a No. 2 positioning hole 04 at the lower part and a No. 4 positioning hole 06 at the upper part. The vertical slide rod 14 is adapted to the No. 4 positioning hole 06. The vertical slide rod 14 is inserted into the No. 4 positioning hole 06 and rotates within the No. 4 positioning hole 06. The vertical slide rod 14 can be controlled to move up and down and rotate by pulling the handle 19 above the circular fence post 01. The handle 19 is connected to the upper part of the vertical slide rod 14, and the horizontal connecting plate 15 is connected to the lower part of the vertical slide rod 14. The column positioning rod 17 is connected to the lower part of the horizontal connecting plate 15.

[0024] Example 4:

[0025] The column positioning rod 17 of this utility model is adapted to the second positioning hole 04. The column positioning rod 17 is inserted into the second positioning hole 04 and slides within the second positioning hole 04.

The upper part of the positioning insertion rod 16 is connected to the horizontal connecting plate 15. The V-shaped support plate 10 has a small diameter hole 12. The positioning insertion rod 16 is adapted to the small diameter hole 12 and is inserted into the small diameter hole 12. The V-shaped support plate 10 has a large diameter hole 13. The positioning anti-detachment plate 18 is adapted to the large diameter hole 13 and passes through the large diameter hole 13, thus positioning the column. The function of rod 17 and positioning rod 16 is to keep the V-shaped support plate 10 perpendicular to the ring fence rod 01. When adjacent ring fence rods 01 are folded together, the vertical slide rod 14 is pulled upward to disconnect the positioning rod 16 from the small diameter hole 12, and the V-shaped support plate 10 is rotated to be horizontal with the ring fence rod 01. At this time, the vertical slide rod 14 is pushed downward to make the positioning anti-detachment plate 18 pass through the large diameter hole 13. The V-shaped support plate 10 is positioned by the column positioning rod 17 to ensure that the V-shaped support plate 10 is retracted to below the ring fence rod 01. This prevents rotation during construction protection. This device is easy to open and fold during use and does not require on-site assembly.
