[0030] Example 1

[0031] Combination Figure 1-6 As shown, this utility model provides a movable construction safety barrier, including at least two barrier components. Each barrier component includes a box 1 and a protective net 2. The barrier component also includes a sleeve 3 fitted over the outside of the box 1. The box 1 has a retraction mechanism 10 for rolling up the protective net 2 inside. The end of the protective net 2 is connected to a connecting rod 11. The connecting rod 11 is detachably connected to the sleeve 3. When not in use, the box 1 is connected to the sleeve 3 through the connecting rod 11, making the overall structure stable and forming a geometric shape, which is convenient for transportation and placement.

[0032] Furthermore, the shrinking mechanism 10 includes a roller 101 that passes through the housing 1; one end of the roller 101 located outside the housing 1 is connected to a handwheel 4 for easy manual operation; the roller 101 is fitted with a collecting rod 102 for winding the protective net 2; the collecting rod 102 is provided with multiple locking blocks 103 to lock the protective net 2 on the collecting rod 102, so that the protective net 2 is more neat when released or wound; the bottom of the housing 1 is provided with a fixing rod 104, and the roller 101 is rotatably connected to the fixing rod 104 to reduce the friction between the roller 101 and the bottom of the housing 1.

[0033] In this embodiment, the side wall of the box 1 is provided with an opening for the protective net 2 to pass through. This opening corresponds to the size of the connecting rod 11. The opening is sealed with the connecting rod 11 to achieve a closed state of the box 1 and thus achieve an anti-oxidation effect. On the corresponding other side, a limiting rod 12 is provided for fixing the connecting rod 11 in the adjacent isolation fence assembly. Threaded holes are provided on both the connecting rod 11 and the limiting rod 12, and the position and size of the holes correspond to each other. The protective net 2 is fixed to the adjacent isolation fence assembly by the connecting rod 11 to maintain the horizontal state of the protective net 2.

[0034] Two limiting ears 31 are provided on one side wall of the sleeve 3 to hold the connecting rod 11 in place, making its structure more stable. Correspondingly, the other side is provided with connecting ears 32 for connecting the protective net 2 in the adjacent isolation fence assembly. The limiting ears 31 and connecting ears 32 are respectively fixed on the opposite side of the sleeve 3. In use, multiple isolation fence assemblies can be arranged in parallel or at right angles to form various shapes to meet the diverse needs of construction.

[0035] Furthermore, a limiting groove is provided on one side wall of the sleeve 3 for the limiting rod 12 to pass through. The box 1 and the sleeve 3 are combined by a snap-fit ​​design. The bottom of the sleeve 3 is provided with multiple universal wheels 33 with built-in locking mechanisms. When moving two isolation barrier components at the same time, the two can be stacked and then moved by pushing and pulling. The operation is simple and saves time.

[0036] Working principle: When a barrier needs to be set up, first lock the caster 33 to the ground, and drive the roller 101 to rotate by pulling the connecting rod 11 with external force. The collecting rod 102 on the roller 101 will rotate accordingly, and gradually release the protective net 2 wrapped on it. As the protective net 2 is released, the connecting rod 11 gradually extends out of the box 1 and is fixed by the limiting rod 12 of the second barrier assembly.

[0037] When the isolation fence needs to be stored, the roller 101 is rotated by the handwheel 4, and the collecting rod 102 on the roller 101 rotates accordingly. The collecting rod 102 rewinds the protective net 2. At the same time, the connecting rod 11 gradually retracts into the box 1 and is fixed by the limiting groove and limiting ear 31 on the sleeve 3.

[0038] Example 2

[0039] Based on Example 1, referring to Figure 4-6As shown, in order to further improve the applicability of the isolation fence, the protective net 2 includes an upper net 21 and a lower net 22. The lower net 22 has a multi-segment structure, and the lower net 22 is folded upward and connected to the upper net 21 to adapt to different height and length requirements. Multiple thin ropes 23 are provided on the upper part of the upper net 21 and on the side of each segment of the lower net 22. A thin film is provided at the connection between the upper net 21 and the lower net 22 to allow the lower net 22 to unfold naturally, so that the protective net 2 can be folded up and down and rolled up without obstruction.

[0040] In this embodiment, a lifting platform 6 is provided at the lower part of the housing 1; the lifting platform 6 is connected to the bottom of the sleeve 3. The lifting platform 6 adopts a scissor-type structure, which can automatically position itself when pulled to the highest state, and can retract under external force. This structure is prior art and will not be described in detail in this application.

[0041] Working principle: Based on the first embodiment, the box 1 is pulled upward to raise the lifting platform 6, so that the box 1 and the sleeve 3 are axially separated and locked at the required height. The thin rope 23 of the net 21 is untied. The folding seam design in the middle of the protective net 2 allows the lower net 22 to unfold naturally. At the same time, the two ends of the lower net 22 are fixed to the limiting ear 31 of the first isolation fence component and the connecting ear 32 of the second isolation fence component, respectively.

[0042] When storing, reverse the above process, fold the lower net 22 upward and fix it with the thin rope 23. At the same time, use external force to retract the box 1 into the sleeve 3. Drive the roller 101 to rotate through the handwheel 4. The collecting rod 102 on the roller 101 will rotate accordingly. The collecting rod 102 will rewind the protective net 2. At the same time, the connecting rod 11 will gradually retract into the box 1 and be fixed by the limiting groove and limiting ear 31 on the sleeve 3.

[0043] Specific application examples

[0044] When used as construction site fencing, such as for urban road renovation, bridge repair, and construction sites, barriers are erected around the construction area to prevent unauthorized personnel from entering dangerous areas. The position or number of barriers can be adjusted according to the construction progress to adapt to different construction stages. When used for demarcating temporary event areas, such as large-scale events like exhibitions, concerts, and sporting events, barriers are used to divide the event area into functional zones such as audience areas, staff areas, and emergency exits, ensuring order at the event site. When used for traffic control, such as at traffic accident scenes, temporary road closures, and traffic control areas, traffic police or road administration departments use barriers to temporarily close roads or set up temporary traffic guidance to guide vehicles and pedestrians to pass in an orderly manner.

[0045] This application provides a movable construction safety barrier. The specific operation process of this device during use is as follows:

[0046] When used for temporary area demarcation, place the first barrier assembly in its initial position, then unscrew the bolts 5 on the connecting rod 11 and the limiting ear 31. Pull the connecting rod 11 and connect it to the limiting rod 12 of the second barrier assembly. Move the second barrier assembly using the casters 33, and simultaneously release the protective net 2 to the required length, then secure the second barrier assembly. When used for construction site or disaster site isolation, based on the above scenario, pull the housing 1 of both barrier assemblies upwards to the highest position of the lifting platform 6. Unscrew the thin rope 23 at the top of the protective net 2, separate the lower net 22 and the upper net 21, and tie the thin rope 23 between each adjacent lower net 22. Secure the lower net 22 closest to the barrier assembly to the limiting ear 31 and the connecting ear 32 respectively. For storage, perform the above-described setup of the protective net 2, then turn the handwheel 4 to rotate the collecting rod 102 to wind around the protective net 2. Finally, retract the housing 1 into the sleeve 3 and secure it with bolts 5.

[0047] In summary, although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
