[0007] The end of the folding bar is provided with a locking groove or a plug post, and the second socket is provided with a plug post or a locking groove for inserting the locking groove or the plug post to lock the end of the folding bar on the corresponding column. The insertion direction between the locking groove and the plug post is perpendicular to the insertion direction between the folding bar and the column, and in the insertion direction of the locking groove and the plug post, the size of the second socket is not less than the sum of the sizes of the first socket and the plug post.

[0008] By adopting this technical solution, the two ends of the folding fence can be directly connected to the columns at both ends by plugging, and then the column middle kit can be raised and lowered on the core rod to achieve relative locking with the columns, so that the folding fence and the two columns are connected as one to form a protective unit, thereby realizing rapid assembly of the protective unit, and ensuring the structural strength of the guardrail, solving the problem of low assembly efficiency of existing guardrails.

[0009] Furthermore, the two upright posts in the protection unit are respectively the first upright post and the second upright post, and the corresponding two core rods are respectively the first core rod and the second core rod;

[0010] The first column set is an inverted U-shaped frame, and a second socket is provided on the flange plate of the inverted U-shaped frame facing the second column, and a third socket with the same structure as the second socket is provided on the flange plate of the inverted U-shaped frame facing away from the second column.

The lower end of the second threaded adjustment knob movably passes through the horizontal plate and is rotatably connected to the top end of the second core rod.

[0015] By adopting this technical solution, a first threaded adjustment knob and a second threaded adjustment knob are provided, and the rotational force of the first threaded adjustment knob and the second threaded adjustment knob are converted into lifting force of the inverted U-shaped frame and the inverted L-shaped frame respectively through the characteristics of thread matching, thereby controlling the lifting of the inverted U-shaped frame and the inverted L-shaped frame respectively, reducing the difficulty of lifting and lowering control of the inverted U-shaped frame and the inverted L-shaped frame.

[0021] The first folding rod and the second folding rod are connected to both sides of the shaft rod in a relatively rotatable manner, and the ends of the first folding rod and the second folding rod facing away from the shaft rod serve as two ends of the folding column respectively.

[0022] By adopting this technical solution, the folding fence itself has a two-part structure of a first folding rod and a second folding rod with the axis rod as the center, that is, the folding fence itself can be folded along the middle part, which can not only adapt to the situation where the guardrail needs to turn, but also reduce the space occupied by the transportation and storage of the folding fence, and can facilitate transportation and storage before and after use.

[0025] The first folding rod and the second folding rod are both rotatably connected to the shaft rod through the cooperation of a collar and a groove.

[0026] By adopting this technical solution, the first folding rod and the second folding rod are stably rotated and connected to the shaft rod respectively through the cooperation of the collar and the groove.

[0027] Furthermore, a limiting sliding groove is provided on one side of the end portion of the first folding rod connected to the shaft, and a sleeve is provided on the end portion of the second folding rod connected to the shaft and on the same side as the limiting sliding groove;

[0028] The folding fence also includes a movable plate, on which a limiting slider slidably engaged with the limiting slide groove and an inserting rod plugged with the inserting sleeve are provided;

[0029] The movable plate is slidably connected to the first folding rod through the cooperation of the limiting slider and the limiting sliding groove, and the sliding of the movable plate can enable the insertion rod to be inserted into the insertion sleeve of the second folding rod, thereby keeping the first folding rod and the second folding rod in a side-by-side unfolded state.

[0030] By adopting this technical solution, after the first folding rod and the second folding rod are rotated to be parallel, the movable plate on the first folding rod can, under the cooperation of the limiting slider and the limiting groove, enable the plug rod connected thereto to move toward the plug sleeve on the second folding rod, and can finally be inserted into the interior of the plug sleeve. At this time, the movable plate itself can serve as a support to limit the relative rotation of the first folding rod and the second folding rod, thereby achieving the purpose of stabilizing the folding bar and ensuring the stability of the folding bar itself.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. The two ends of the folding fence can be directly connected to the columns at both ends by plugging.
