[0002] During urban road construction, maintenance, renovation and other projects, it is necessary to temporarily set up isolation fences to separate the construction area to prevent construction workers and passing pedestrians and vehicles from entering the construction area, and to ensure construction safety and traffic order.

[0003] The patent with the patent authorization announcement number CN210685588U discloses a temporary isolation guardrail for construction sites. The patent can adapt to different environments through the counterweight setting and the conical tip to enhance the stability when placed. The connecting parts and the connecting plates are then installed to each other, so that two adjacent devices can be connected and fixed to each other to enhance the stability between the devices. However, the patent still has some shortcomings. The isolation length range of the patent itself is fixed, and the isolation length range needs to be adjusted by splicing and disassembling multiple devices. It is more troublesome to use and it is not convenient to adjust to the appropriate range according to the construction area.

[0004] Therefore, there is an urgent need to provide a temporary isolation guardrail for traffic engineering construction that can conveniently and flexibly adjust the isolation length range. Utility Model Content

[0011] As a further preferred solution, a box cover is hinged on the weighted box, and a fixing piece is provided on the weighted box, through which the weighted box can be clamped on the extension rod, and a fixing screw is threadedly provided on the fixing piece.

[0012] As a further preferred solution, the fixing block and the extension rod are jointly connected with a telescopic protection plate.

[0013] As a further preferred solution, a plurality of buffer strips are provided on the anti-collision barrel.

[0014] Compared with the prior art, the utility model has the following technical effects: 1. By pulling the extension rod outward to detach from the railing, it can be stretched to an appropriate length according to the scope of the construction area, and the telescopic isolation frame will be unfolded to the length for protection, thus achieving convenient and flexible adjustment of the length range.

[0015] 2. By rotating the anti-collision barrel, the torsion spring is deformed to provide buffering, reducing the impact force on the railing, thereby protecting the railing and the impact object.

[0016] 3. The warning light can be activated to emit bright light, which can provide reminders and warnings at night, thereby improving the conspicuousness of the device.

[0017] 4. Open the box cover and put the counterweight into the weight box to increase the weight of the device, so as to improve the stability of the device and prevent the device from shifting or tipping over when it is hit. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The present invention is further described below in conjunction with specific embodiments. It should also be noted that, unless otherwise clearly specified and limited, terms such as: setting, installing, connecting, and connecting should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Example 1: Please refer to Figure 1 and Figure 2 A temporary isolation guardrail for traffic engineering construction includes a railing 1, and the left and right parts of the railing 1 are both provided with fixed blocks 2. The fixed block 2 is provided with a telescopic isolation frame 3, and the telescopic isolation frame 3 can be deployed and retracted for protection. An extension rod 4 is fixedly connected to the telescopic isolation frame 3, and the extension rod 4 can be clamped with the railing 1 to fix the extension rod 4 on the railing 1. The fixed block 2 and the extension rod 4 are jointly connected with a telescopic protection plate 15, and the telescopic protection plate 15 is used to protect the telescopic isolation frame 3.

[0025] When in use, place the device on the ground, then pull the extension rod 4 outward to separate it from the railing 1, and then pull the extension rod 4 to a suitable length according to the scope of the construction area, and the telescopic isolation frame 3 will be unfolded to the length for protection, thus achieving convenient and flexible adjustment of the length range.

[0026] Example 2: Based on Example 1, please refer to Figure 3 Three vertically distributed fixing rods 5 are equidistantly fixed to the middle of the railing 1, and an anti-collision barrel 6 is rotatably connected to the fixing rod 5. The anti-collision barrel 6 and the fixing rod 5 are commonly connected with a torsion spring 7. The anti-collision barrel and the torsion spring 7 cooperate to provide buffering protection for the railing 1, and the anti-collision barrel 6 is provided with 12 equidistantly distributed buffer strips 16, which are used to protect the anti-collision barrel 6 and improve the anti-collision performance of the anti-collision barrel 6.

[0027] When the railing 1 is hit, the anti-collision barrel 6 rotates to deform the torsion spring 7 to provide buffering, thereby reducing the impact force on the railing 1 and protecting the railing 1 and the impacted object.

[0028] See also Figure 3Two warning lights 8 symmetrically distributed on the left and right are arranged on the top of the railing 1. The warning lights 8 are used for safety warnings. A support frame 9 is arranged on the warning lights 8. A solar panel 10 located above the warning lights 8 is arranged on the top of the support frame 9. The solar panel 10 is used to power the warning lights 8.

[0029] When the device is used at night, the warning light 8 is turned on to emit a bright light for reminders and warnings, thereby improving the conspicuousness of the device. When used during the day, the warning light 8 is turned off, and the solar panel 10 absorbs solar energy to power the warning light 8, thereby eliminating the need to use external power resources for power supply, saving electricity, and facilitating use.

[0030] See also Figure 1 and Figure 4 A box cover 12 is hinged on the front side of the top of the weighted box 11, and two fixing parts 13 symmetrically distributed on the left and right are arranged on the top of the weighted box 11. The weighted box 11 can be clamped on the extension rod 4 by the fixing parts 13 to increase the weight of the extension rod 4. A fixing screw 14 is threadedly arranged on the fixing part 13, and the fixing part 13 can be closed and opened by rotating the fixing screw 14 forward and backward.

[0031] After the length range of the device is adjusted, the box cover 12 is opened and a counterweight is placed in the weight box 11 to increase the weight of the device, thereby improving the stability of the device and preventing the device from being displaced or tipped over when it is hit.
