[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 As shown, this utility model provides a technical solution:

[0021] A convenient, detachable municipal road construction fence includes a base pier 1. The top of the base pier 1 has symmetrically symmetrically formed slots 12. The interior of the base pier 1 is symmetrically connected to limit blocks 7. The interior of the base pier 1 also has symmetrically formed moving grooves 13. Two limit blocks 7 slide along the two moving grooves 13 respectively. A through groove 11 is formed on the base pier 1 between the two moving grooves 13. A double-ended screw 6 is rotatably connected to the interior of the base pier 1 via bearings. The middle part of the double-ended screw 6 is located in the through groove 11, and an adjusting sleeve 61 is sleeved on the middle part of the double-ended screw 6. The threads at both ends of the double-ended screw 6 have opposite directions of rotation, and two screws are respectively threaded into the two ends of the double-ended screw 6. In the limiting block 7, a column 2 is inserted into each of the two slots 12. A limiting groove 21 is formed at the lower end of each column 2, and the limiting block 7 is inserted into the limiting groove 21. A marker baffle 5 is inserted between the two columns 2. A slot 22 for inserting the marker baffle 5 is formed on the inner wall of each column 2. By inserting the lower ends of the two columns 2 into the two slots 12 at the top of the pier 1, and manually rotating the double-ended screw 6 clockwise, the two limiting blocks 7 are inserted into the limiting grooves 21 at the lower ends of the two columns 2, and the marker baffle 5 is inserted between the two slots 22, the construction enclosure for the municipal road is completed. The construction site fence can be quickly dismantled by pulling the signage baffle 5 out of the insertion slot 22 and rotating the double-ended screw 6 counterclockwise to move the two limiting blocks 7 out of the limiting groove 21. This allows the column 2 to be pulled out of the slot 12, making the process convenient. When erecting the construction fence, the base pier 1 can be moved and placed in a suitable position on the road without drilling holes in the ground for bolt fixing, thus better protecting the road surface. Next, the lower ends of the two columns 2 are inserted into the two slots 12 at the top of the base pier 1, and then the adjusting sleeve 61 is manually rotated clockwise to move the double-ended screw... Rotating rod 6 causes the double-ended screw 6 to rotate, which in turn moves the two limiting blocks 7 along the moving groove 13 and inserts them into the limiting grooves 21 at the lower ends of the two columns 2. Then, the signage baffle 5 is inserted between the two insert slots 22, thus completing the rapid erection of the municipal road construction fence. After the road construction is completed, the signage baffle 5 can be pulled out of the insert slot 22, and the adjusting sleeve 61 can be rotated counterclockwise to drive the double-ended screw 6 to rotate. The rotation of the double-ended screw 6 can drive the two limiting blocks 7 to move out of the limiting grooves 21, thus allowing the columns 2 to be pulled out of the slots 12, completing the rapid dismantling of the municipal road construction fence.

[0022] A connecting frame 3 is provided between the two columns 2. The connecting frame 3 includes a rectangular bar 31, a rectangular sleeve 32, and a locking bolt 33. One end of the rectangular bar 31 is movably disposed in the rectangular sleeve 32, and the other end of the rectangular bar 31 is fixedly connected to one side of the column 2. The end of the rectangular sleeve 32 away from the rectangular bar 31 is fixedly connected to the other side of the column 2. The locking bolt 33 is threadedly screwed into the front of the rectangular sleeve 32 at a position away from the column 2, and one end of the locking bolt 33 abuts against the rectangular bar 31. Telescopic rods 4 are fixedly connected between the two columns 2 on both the upper and lower sides of the connecting frame 3. Two telescopic rods 4 are provided on both the upper and lower sides of the connecting frame 3. The two ends are fixedly connected to the two columns 2 respectively. The identification baffle 5 is set on the rear side of the connecting frame 3. By setting the connecting frame 3 and the telescopic rod 4 between the two columns 2, the two columns 2 can be folded together after dismantling, thereby reducing the space occupied during transportation and making it easier to move and transport. After the municipal road construction fence is dismantled, the two columns 2 can be brought closer to each other and folded together by the connecting frame 3 and the telescopic rod 4 until one of the columns 2 abuts against the rectangular sleeve 32. Then, the locking bolt 33 is manually tightened to lock the rectangular strip 31, which reduces the space occupied during the transportation of the construction fence and makes it easier to move and transport.

[0023] Working principle: When using this system, the base pier 1 can be moved and placed in a suitable position on the road during the construction of a municipal road. No drilling or bolt fixing is required, providing better protection for the road surface. Next, the lower ends of the two uprights 2 are inserted into the two slots 12 at the top of the base pier 1. Then, manually rotating the adjusting sleeve 61 clockwise rotates the double-ended screw 6. The rotation of the double-ended screw 6 moves the two limiting blocks 7 along the moving groove 13 and inserts them into the limiting grooves 21 at the lower ends of the two uprights 2. Finally, the signboard 5 is inserted between the two slots 22, completing the rapid erection of the municipal road construction fence. After construction is completed, the signage baffle 5 can be pulled out from the insert slot 22, and the adjusting sleeve 61 can be rotated counterclockwise to drive the double-headed screw 6 to rotate. The rotation of the double-headed screw 6 can drive the two limiting inserts 7 to move out of the limiting groove 21, so that the column 2 can be pulled out from the slot 12, thus completing the quick dismantling of the municipal road construction fence. After the municipal road construction fence is dismantled, the two columns 2 can be brought closer together by the connecting frame 3 and the telescopic rod 4 until one of the columns 2 abuts against the rectangular sleeve 32. Then, the locking bolt 33 can be manually tightened to lock the rectangular strip 31, which can reduce the space occupied during the transportation of the construction fence and make it easier to move and transport.
