[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] like Figures 1 to 4As shown, a highway construction warning fence includes multiple parallel fixed poles 1, the bottom ends of which are inserted into the ground. A fence panel 2 is detachably installed between every two adjacent fixed poles 1. Multiple vertically parallel connecting crossbars 3 are also detachably fixed between every two adjacent fixed poles 1. Multiple sets of vertically symmetrically distributed rotating connecting blocks 5 are rotatably installed on the surface of the fence panel 2 facing the connecting crossbars 3. A snap-fit ​​groove 10 is provided on the inner side of one end of the rotating connecting block 5. The rotating connecting block 5 is snapped onto the outer side of the connecting crossbar 3 through the snap-fit ​​groove 10. A limiting insertion hole 11 is provided on one side of the rotating connecting block 5. An insertion rod 9 is inserted into the inner side of the limiting insertion hole 11. The two vertically symmetrical rotating connecting blocks 5 surround the connecting crossbar 3, and the two vertically symmetrical rotating connecting blocks 5 are fixed by the insertion rod 9, ensuring that the rotating connecting blocks 5 cannot be opened after being connected to the connecting crossbar 3, thus ensuring the stability of the fence panel 2 after installation.

[0020] Multiple crossbar overlapping blocks 4 are fixed on the outer surface of the fixed upright 1. Both ends of the crossbar overlapping blocks 4 are provided with positioning grooves 6. The end of the connecting crossbar 3 is inserted into the inner side of the positioning groove 6, and the width of the positioning groove 6 is consistent with the diameter of the connecting crossbar 3. The connecting crossbar 3 and the fixed upright 1 are connected by the crossbar overlapping blocks 4, so that after the rotating connecting block 5 is connected to the connecting crossbar 3, the fixed upright 1 and the connecting crossbar 3 are located in front and behind the fixed upright 1 respectively, thereby ensuring that the connecting crossbar 3 and the enclosure baffle 2 will not easily separate from the fixed upright 1.

[0021] A connecting rod 8 is inserted through the end of the rotating connecting block 5 near the fence baffle 2. Both ends of the connecting rod 8 are fitted with end fixing blocks 7. One end of the end fixing block 7 is fixed to the fence baffle 2, and the other side of the end fixing block 7 contacts the rotating connecting block 5. The connecting rod 8 and the end fixing blocks 7 rotate the rotating connecting block 5 to the fence baffle 2, so that the rotating connecting block 5 can rotate freely, and realize the engagement or disengagement of the rotating connecting block 5 and the connecting crossbar 3.

[0022] The plug rod 9 has a U-shaped structure with its two ends parallel to each other. The two ends of the plug rod 9 are respectively inserted into the limiting plug holes 11 on the sides of the two symmetrical rotating connecting blocks 5. When the two rotating connecting blocks 5 are attached to each other and surround the connecting crossbar 3 through the snap-fit ​​groove 10, the plug rod 9 is used to snap and lock the two rotating connecting blocks 5, thereby ensuring that the two rotating connecting blocks 5 clamp the connecting crossbar 3 tightly and cannot be separated.

[0023] Working principle: When assembling the highway construction warning fence, first insert the bottom end of the fixed pole 1 into the ground, and then fix adjacent fixed poles 1 at equal intervals. After the fixed poles 1 are installed, snap the end of the connecting crossbar 3 into the positioning groove 6 at the end of the crossbar overlapping block 4. At this time, connect the fence baffle 2 to the fixed pole 1, ensuring that the bottom of the fence baffle 2 is in contact with the ground. After the fence baffle 2 and the fixed pole 1 are attached, the worker rotates the rotating connecting block 5 around the connecting rotating rod 8, causing the rotating connecting block 5 to rotate towards the connecting crossbar 3 and causing the snapping groove 10 to cover the connecting crossbar 3. When the rotating connecting block 5 surrounds the connecting crossbar 3, the two ends of the plug rod 9 are respectively inserted into the limiting plug holes 11 on the side of the two rotating connecting blocks 5, and the plug rod 9 is pressed until the end of the plug rod 9 is deeply inserted into the limiting plug hole 11 and cannot move. At this time, the connecting crossbar 3 is fixed to the connecting crossbar 3 by the two rotating connecting blocks 5, and the fence baffle 2 and the connecting crossbar 3 surround the fixed upright 1 from the front and rear, quickly completing the installation and fixing of the fence baffle. During the installation process, there is no need to use other fasteners such as wire, screws or rivets, which simplifies the construction process of the fence, shortens the construction time of the fence, and effectively improves the construction efficiency of the fence.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
