The setting of the auxiliary assembly 400 facilitates the lifting and overall movement of the protective fence.

[0040] Please refer to the accompanying drawings: Figures 1 to 4 show the protective fence according to the present application. Figure 2 , Figures 5 to 8 show the protective fence according to the present application. Figure 3 Preferably, the supporting piece 200 comprises a supporting arm 201, one end of the supporting arm 201 is movably inserted into the limiting sleeve 101, a threaded hole 203 is formed on the end face of one end of the supporting arm 201, threaded sections are formed on both sides of the bidirectional screw rod 300, and the threaded sections are matched and screwed with the threaded hole 203 after penetrating through the limiting sleeve 101.

[0041] Preferably, the supporting arm 201 and the limiting sleeve 101 are made of square steel pipes, the specification of the supporting arm 201 is one size smaller than that of the limiting sleeve 101, so as to satisfy the telescopic sliding of the supporting arm 201 relative to the limiting sleeve 101, and the relative torsion is avoided.

[0042] The length of the threaded section of the bidirectional screw rod 300 can be determined according to the telescopic range of the supporting arm 201, the threaded hole 203 is arranged at one end of the supporting arm 201, the supporting arm 201 cannot rotate in the limiting sleeve 101 due to its structure, so that the rotation of the bidirectional screw rod 300 is converted into the linear motion of the supporting arm 201 along the axis of the bidirectional screw rod 300 by screw transmission, so that the supporting arm 201 is extended out of or retracted into the limiting sleeve 101.

[0043] The thread directions of the two thread sections of the bidirectional screw 300 can be reversely arranged, so that the bidirectional screw 300 can drive a pair of support arms 201 to move synchronously, the pair of support arms 201 move synchronously to approach or move away from each other, and then the pair of support arms 201 can adapt to door and window openings with different widths.

[0047] Because the convex grooves on both sides of the bottom of the limiting sleeve 101 protrude from the bottom surface of the limiting sleeve 101, the contact area between the bottom surface of the limiting sleeve 101 at the bottom of the limiting assembly 100 and the bottom surface of the door and window opening is reduced, which affects the stability of the installation. Through the arrangement of the convex block 110, the contact area between the limiting sleeve 101 at the bottom of the limiting assembly 100 and the bottom surface of the door and window opening is ensured, so that the protection effect is ensured.

[0048] Please refer to the accompanying drawings Figure 1 to the accompanying drawings Figure 4 The use method and working principle of the utility model are as follows:

[0049] The construction personnel hold the protective fence of the utility model by the handle 401 and move it to the door and window opening, and the convex block 110 is attached to the bottom surface of the door and window opening. According to the width of the door and window opening, the bidirectional screw 300 is rotated, the rotation of the bidirectional screw 300 is converted into the linear motion of the support arm 201 along the thread section of the bidirectional screw 300 under the transmission of the thread, a pair of support arms 201 respectively extend a pair of limiting sleeves 101 and are tightly pressed against the two side walls of the door and window opening, and the clamping plate 202 is attached to the wall surface on the indoor side of the door and window opening. According to the requirement of the protection height, the telescopic rod 105 is telescoped relative to the support rod 104, the height of the limiting assembly 400 is adjusted, the adjusting bolt 106 is screwed into the telescopic rod 105 after the adjustment is completed, and the installation and adjustment of the protective fence are completed.

[0050] The abutting between the supporting arm 201 and the side wall of the door and window hole and the fitting between the clamping plate 202 and the indoor side wall of the door and window hole provide two-way limiting for the protective fence, which greatly improves the protection effect of the protective fence without bolt reinforcement, and takes into account the finished product protection of the wall surface and the protection effect of the door and window hole.

[0051] When the construction personnel hits the protective fence, the clamping plate 202 transmits the impact force to the wall surface on the indoor side of the door and window hole, greatly sharing the stress at the connecting part of the supporting arm 201 and the side wall of the door and window hole, avoiding the relative sliding of the supporting arm 201 and the side wall of the door and window hole to cause protection failure, and ensuring the protection effect of the door and window hole.

[0052] The above is only a preferred embodiment of the present application, and is not used to limit the protection scope of the present application, therefore, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
