[0023] Refer to Figure 1 - Figure 2 , an embodiment of the present utility model provides a temporary staircase protection structure, including a plurality of column units 10 and a plurality of guardrail units 20. One or more of the guardrail units 20 are provided between two adjacent column units 10. The column unit 10 includes a column main body 101 and a hinge assembly. There is one or more hinge assemblies, which are installed at any position on the column main body 101 and are hinged to the guardrail unit 20;

[0024] The articulated assembly includes a first rotating connecting member and a second rotating connecting member. The first rotating connecting member and the second rotating connecting member are snap-fitted and stacked, and both can rotate around the column body 101. The first rotating connecting member and the second rotating connecting member both include a connecting seat 103. The first rotating connecting member further includes two first rotating rings 102, which are respectively connected to the same side of the connecting seat 103 at upper and lower intervals. The second rotating connecting member further includes a second rotating ring 108, which is centrally connected to one side of the connecting seat 103 and is snap-fitted between the two first rotating rings 102.

[0025] In the present utility model, the first rotating ring and the second rotating ring are snap-fitted and stacked, and are rotatable relative to each other, so that the first rotating connecting member and the second rotating connecting member can be relatively rotated and adjusted, meeting the multi-angle installation requirements of the articulated assembly for two adjacent guard rail units, and also meeting the construction protection requirements of stairs with different bending angles. It is more flexible and convenient to use, avoiding the problem in the prior art that different columns need to be customized for temporary protection for stairs with different bending angles.

[0026] See Figure 1 , in this embodiment, a plurality of the articulated assemblies are respectively distributed at intervals along the height direction of the column body 101. A plurality of the guard rail units 20 are respectively distributed at intervals along the height direction of the column body 101 between two adjacent column units 10, and the articulated assembly is rotatably connected to the end of the guard rail unit 20. With such a design, two adjacent column bodies 101 are connected to form a section of guard rail structure under the articulation of the guard rail unit 20 for the safety protection of the temporary stairs. The number of the guard rail units 20 specifically installed between two adjacent column units 10 can be determined according to actual construction requirements.

[0027] See Figure 2 , in this embodiment, the first rotating ring 102 or the second rotating ring 108 can be rotatably sleeved on the column body 101, and the inner diameter sizes are both matched with the outer diameter size of the column body 101. With such a design, the first rotating ring 102 or the second rotating ring 108 can drive the connecting seat 103 to rotate around the column body 101, facilitating the adjustment of the angle between the first rotating connecting member and the first rotating connecting member. In this way, the installation requirements of stairs with different bending angles can be met, and it is more convenient to use, avoiding the problem in the prior art that different column units 10 need to be customized for temporary protection for stairs with different bending angles.

[0028] See Figure 3, in this embodiment, the guard bar unit 20 includes a guard bar main body 201 and connecting heads 202. The guard bar main body 201 is selected as a telescopic rod structure with an adjustable rod length. There are two connecting heads 202, which are respectively ball-jointed at both ends of the guard bar main body 201 and can rotate around the circumference of the guard bar main body 201. With such a design, the guard bar main body 201 is designed as a telescopic rod structure, which can meet the installation requirements at different distances. The connecting heads 202 are located at the ends of the guard bar main body 201. They can not only rotate around the circumference of the guard bar main body 201 but also swing back and forth around the ball-joint point, meeting the flexibility of multi-angle installation. Among them, the telescopic rod structure and the ball-joint are both prior arts, so no more details will be elaborated here.

[0029] See Figure 2 , in this embodiment, the connecting seat 103 has a U-shaped structure and includes a first tooth 104 and a second tooth 105 that are spaced apart. The connecting head 202 can be inserted into the space between the first tooth 104 and the second tooth 105 and is threadedly connected to the connecting seat 103 via a bolt 106. With such a design, according to the installation positions of the current adjacent two column units 10, adjust the rotation angles and ball-joint angles of the respective connecting heads 202 at both ends of the guard bar main body 201 until the connecting heads 202 are smoothly inserted between the first tooth 104 and the second tooth 105 and are locked and fixed under the threaded locking of the bolt 106, so that the guard bar main body 201 is adjustably connected between the adjacent two guard bar main bodies 201.

[0030] See Figure 2 - Figure 3 , in this embodiment, an installation hole 203 is provided on the connecting head 202, a threaded hole is provided on the first tooth 104, and a through hole is provided on the second tooth 105. The installation hole 203, the threaded hole, and the through hole are concentrically arranged. The bolt 106 passes through the through hole and the installation hole 203 in sequence and is locked with the threaded hole. With such a design, after the connecting head 202 is inserted between the first tooth 104 and the second tooth 105, adjust the position of the installation hole 203 until the bolt 106 can smoothly penetrate the through hole, the installation hole 203, and the threaded hole, and then smoothly fix the connecting head 202 to be hinged on the connecting seat 103.

[0031] See Figure 2, in this embodiment, a ring 107 is rotatably mounted on the bolt member 106, an elastic member 109 is connected to the outer side of the second engaging tooth 105, and the elastic member 109 is connected to the ring 107. With such a design, under the connection action of the elastic member 109 and the ring 107, the bolt member 106 is rotatably connected to the outer side of the second engaging tooth 105. During installation, the bolt member 106 can be directly inserted into the second engaging tooth 105 to complete the locking of the connection head 202. One person can complete the installation, which is more convenient in operation, improves work efficiency, and avoids the dangerous construction phenomenon of the elastic member 109, the ring 107 or the bolt member 106 falling from a height.

[0032] See Figure 2 , in this embodiment, the column unit 10 further includes a base 110, and the base 110 is fixed to the bottom of the column main body 101 and is used for supporting and installing the column unit 10. With such a design, during actual operation, a plurality of fixing holes can be provided on the base 110 to facilitate the fixed installation of the column unit 10 at a specified position on the staircase. It should be noted that the column main body 101 is preferably selected to have a cylindrical structure to facilitate the installation of the hinge assembly, and other structures can also be selected as long as it does not prevent the normal installation and use of the hinge assembly.

[0033] In summary, in the present utility model, the first rotating ring and the second rotating ring are engaged and stacked, and are rotatable relative to each other, so that the first rotating connecting member and the second rotating connecting member can be relatively rotated and adjusted, meeting the multi-angle installation requirements of the hinge assembly for two adjacent guardrail units, and also meeting the construction protection requirements of staircases with different bending angles. It is more flexible and convenient to use, and avoids the problem in the prior art that different columns need to be customized for temporary protection for staircases with different bending angles;

[0034] At the same time, under the connection action of the elastic member and the ring, the bolt member is rotatably connected to the outer side of the second engaging tooth. During installation, the bolt member 106 can be directly inserted into the second engaging tooth until it penetrates through the connection head and is threadedly connected to the first engaging tooth to complete the locking of the connection head. One person can complete the installation, which is more convenient in operation, improves work efficiency, and avoids the dangerous construction phenomenon of the elastic member, the ring or the bolt member falling from a height.
