[0033] In the embodiment of the utility model, the wrench seat 1521 set on both sides of the column 1 can enable the staff to control the adjustment of the pin 1421 from both sides of the column, which is convenient for the staff's operation and prevents the connecting cross bar 2 from moving out of the cross bar fixing seat 3 when the pin 1421 is adjusted.

[0034] The connecting cross bar 2 is arranged between the two columns 1. There are multiple connecting cross bars 2, which are composed of a connecting cross tube 21, an inserting cylinder 22 and a square inserting block 23. The inserting cylinder 22 is installed at both ends of the connecting cross bar 2 and is movably inserted in the inserting circular groove 132. The square inserting block 23 is installed at one end of the inserting cylinder 22 and is movably inserted in the square inserting groove 133. A pin groove 231 is opened at the center of the lower surface of the square inserting block 23.

[0035] In the embodiment of the utility model, the connecting cross bar 2 is spliced ​​by the connecting cross tube 21, the plug-in cylinder 22 and the square plug-in block 23. The plug-in cylinder 22 is inserted into the plug-in circular groove 132, and the plug-in cylinder 22 is partially located outside the cross bar fixing seat 13, which can ensure the stability of the insertion of the connecting cross bar 2 and the column 1. The square plug-in block 23 is inserted into the square plug-in groove 133, which can facilitate the alignment of the pin hole 134 and the pin groove 231 on the one hand, and improve the installation efficiency of the device on the other hand.

[0036] As a detachable guardrail device for construction projects of the utility model, after the square insertion block 23 is inserted into the square insertion slot 133, the latch slot 231 is aligned with the latch hole 134, so that the latch 1421 can be inserted into the latch slot 231; the disassembly and assembly of the device can be facilitated and the disassembly and assembly efficiency can be improved.

[0037] As a detachable guardrail device for construction projects of the utility model, the circular magnet 1422 contacts the upper surface of the latch slot 231, and the latch 1421 is adsorbed in the latch slot 231 through magnetic force; the stability of the insertion of the latch 1421 can be ensured, and the problem of the latch 1421 being moved out of the latch slot 231 due to gravity can be avoided, thereby ensuring the stability and firmness of the device after splicing.

[0038] As a detachable guardrail device for construction projects of the utility model, the two crossbar fixing seats 13 at the same position inside the column 1 can be set at 90°, so that the direction of the guardrail can be changed according to actual conditions during assembly, making the assembly of the guardrail more convenient.

[0039] As a detachable guardrail device for construction projects of the utility model, when the adjusting round rod 151 moves to the bottom of the adjusting dial 15, the latch 1421 is moved out of the latch slot 231, while still being inserted in the latch hole 134; this prevents the latch 1421 from being unable to be inserted into the latch hole 134 after being moved out of the latch hole 134, thereby ensuring smooth adjustment of the latch 1421.

[0040] When using the device, the staff takes out two columns 1 and several connecting cross bars 2, and places one of the columns 1 in a suitable position and fixes it to the ground with anchor bolts. Then the staff takes out the connecting cross bar 2, and inserts the plug-in cylinder 22 at one end of each column into the plug-in circular groove 132 in the cross bar fixing seat 13 on the current column 1, while ensuring that the latch groove 231 on the square plug-in block 23 faces downward, and then adjusts the square plug-in block 23 to align with the square plug-in groove 133, and inserts the square plug-in block 23 into the square plug-in groove 133;

[0041] When one end of all the connecting cross bars 2 is inserted into the current column, the staff takes out the wrench and inserts it into the wrench seat 1521. Then, by turning the wrench, the wrench seat 1521 drives the adjusting short shaft 152 to rotate, and the adjusting dial 15 drives the adjusting round rod 151 to rotate and adjust, and then drives the adjusting rod 14 to move through the adjusting cross bar 141, so that the adjusting rod 14 drives the adjusting baffle 142 to move upward, and the pin 1421 is inserted into the square insertion slot 133 through the pin hole 134, and also inserted into the pin slot 231, until the pin 1421 is fully inserted.

[0042] When the wrench seat 1521 rotates 180°, the latch 1421 is fully inserted into the latch slot 231, and one end of the connecting cross bar 2 is fixed to the current column 1; the latch 1421 is fixed by the magnetic force between the circular magnet 1422 and the latch slot 231.

[0043] Then the staff takes out another column 1 and places it on the other end of the connecting cross bar 2, and then moves the other column 1 to gradually insert the other end of the connecting cross bar 2 into the cross bar fixing seat 13 on this column. When the connecting cross bar 2 is fully inserted into this column 1, a wrench can be inserted into the wrench seat 1521 on this column 1, and the wrench seat 1521 can be rotated 180°, so that the pin inside this column 1 is inserted into the square insertion slot 133, and also inserted into the pin slot 231 on the square insertion block 23, thereby completing the assembly of the guardrail.

[0044] When the guardrail needs to be extended, the staff only needs to take out the columns 1 and connecting cross bars 2 to be used subsequently, and install and splice the connecting cross bars 2 and the columns 1 one by one in the above-mentioned manner.

[0045] When the installation direction of the guardrail needs to be changed, the staff can take out the column 1 with adjustable guardrail angle, and the crossbar fixing seat 13 at the same position inside it is in a vertical setting. The staff can still install the connecting crossbar 2 and the column 1 in the above manner.
