[0035] The longitudinal section of the locking block 12 is wedge-shaped, the other end of the connecting rod 8 and the inclined surface of the locking block 12 selectively abut, and the edge of the other end of the connecting rod 8 is arc-shaped.

[0036] With reference to Figure 5 The support folding assembly comprises a support base 18, a first movable rod 20, a second movable rod 22, a fixed block 23 and a bolt 24, one end of the support base 18 is hinged to the storage groove 4, a storage groove 19 is arranged at the upper end of the support base 18, the first movable rod 20 is hingedly arranged in the storage groove 19, an active groove 21 is arranged at the upper end of the first movable rod 20, the active groove 21 is slidably connected with the second movable rod 22, the end of the second movable rod 22 away from the first movable rod 20 is connected with the fixed block 23, the fixed block 23 is detachably connected with the limiting hole 5, and the first movable rod 20 and the second movable rod 22 are both provided with a insertion hole, and the two insertion holes are both inserted with the bolt 24.

[0037] When the support folding assembly is not needed, it can be folded and stored in the storage groove 4. At this time, the first movable rod 20 and the second movable rod 22 are both in the contracted state, the bolt 24 is pulled out of the insertion hole, and the hinged point of the support base 18 and the storage groove 4 is in the folded position.

[0038] When the support folding assembly is needed, first, the support base 18 is taken out of the storage groove 4 and placed on the ground to keep it in a parallel state, then the first movable rod 20 is rotated, after that, the second movable rod 22 is pulled out of the first movable rod 20, so that the insertion hole of the first movable rod 20 and the insertion hole of the second movable rod 22 are aligned, then the bolt 24 is inserted into the two insertion holes to fix the first movable rod 20 and the second movable rod 22 together, finally, the fixed block 23 is inserted into the limiting hole 5 to realize the stable locking of the support folding assembly.

[0039] The storage groove 4 is provided with a fixing hole in the vertical direction, the fixing member 25 is an expansion screw, and the fixing member 25 is detachably connected with the ground through the fixing hole.

[0040] The upper end of the lifting rod 6 is provided with a handle 26, and the handle 26 is an embedded handle. When in use, the staff releases the connection between the limiting pin 10 and the second through hole 3, then lifts the handle 26 to adjust the height of the lifting rod 6, and then inserts the limiting pin 10 into the first through hole to connect with the second through hole 3.

[0041] The side wall of the support rod 1 is provided with a binding member 27, which is a strap. The edge of the support rod 1 is arc-shaped. When the device is no longer in use, the staff puts the support folding assembly into the storage slot 4, and then uses the binding member 27 to bind the support folding assembly to the support rod 1. The arc-shaped design of the edge of the support rod 1 can reduce the friction between the binding member 27 and the edge, thereby extending the service life of the binding member 27.

[0042] A connecting ring 28 is provided on the opposite side wall of the support rod 1. According to the working area of ​​the highway construction, the adjacent devices are connected by a warning tape with light-emitting function (not shown in the figure), and the warning tape can be tied to the connecting ring 28.

[0043] The working principle of this utility model is as follows: When in use, the staff places the support rod 1 around the construction site, releases the binding 27 from the restriction of the support folding assembly, then takes the support base 18 out of the storage slot 4 and unfolds it, rotates the first movable rod 20, pulls out the second movable rod 22 and aligns it with the insertion hole of the first movable rod 20, then inserts the pin 24 to fix the first movable rod 20 and the second movable rod 22, and then inserts the fixing block 23 into the limiting hole 5 to lock the support folding assembly.

[0044] When the height of the warning plate 9 needs to be adjusted, the staff first disconnects the limit pin 10 and the second through hole 3, then slides the lifting rod 6 up and down along the slide groove 2 by pulling the handle 26, and adjusts the lifting rod 6 to the required height. Finally, the limit pin 10 is reinserted into the first through hole and the corresponding second through hole 3 to fix the height of the lifting rod 6.

[0045] In addition, the warning plate 9 is connected to the fixed sleeve 7 via the connecting rod 8. Its purpose is to convey the information of "construction section" to pedestrians. When the connecting rod 8 is inserted into the fixed sleeve 7, the inclined surface of the locking block 12 contacts the arc edge of the connecting rod 8. As the connecting rod 8 goes deeper, the locking block 12 is gradually compressed until the spring 17 is fully compressed. When the connecting rod 8 is fully inserted into the fixed sleeve 7, the locking block 12 extends into the limiting groove 11 and locks the connecting rod 8. Pulling the stop rod 16 can easily unlock the connecting rod 8 and achieve rapid release.

[0046] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0047] The above-described embodiments are merely preferred modes of the present application, and are not intended to limit the scope of the present application, and various modifications and improvements to the technical solutions of the present application made by those of ordinary skill in the art without departing from the design spirit of the present application shall fall within the protection scope of the present application as defined by the claims.
