[0032] Reference Figure 1 and Figure 6The utility model provides a tiltable guardrail, including a crossbeam 1, a vertical tube 2, an angle adjustment unit of a column 3 and a connecting unit 4. A plurality of vertical tubes 2 are connected to a plurality of crossbeams 1 through the angle adjustment unit. The vertical tubes 2 and the crossbeam 1 can adjust the angle between the two through the angle adjustment unit so that when the crossbeam 1 is tilted relative to the horizontal plane, the vertical tube 2 can be vertically set relative to the horizontal plane. The end of the crossbeam 1 is detachably connected to the column 3 through the connecting unit 4. The column 3 is pre-buried by digging a pit in the ground to form a fixation with the ground, and the column 3 always remains in a vertical state.

[0033] Different from the welded crossbeam and vertical tube of ordinary guardrail, the tiltable guardrail, with the assistance of the angle adjustment unit, can flexibly adjust the angle between the vertical tube 2 and the crossbeam 1, so that the crossbeam 1 can be tilted left and right, and the vertical tube 2 always remains vertical, so that the guardrail can be tilted at a certain angle, and the angle between the crossbeam 1 and the column 3 can be adjusted as the slope rises and falls, thus solving the problem of installing the guardrail on a slope. The overall structure is simpler and easy to disassemble and assemble.

[0034] As an optional implementation, each crossbeam 1 is provided with a plurality of long holes 12 on the plumb plane, each crossbeam 1 is provided with a first circular hole 11 penetrating through the horizontal plane at the corresponding position of each long hole 12, each vertical tube 2 is provided with a second circular hole 21 at the corresponding position connected to each crossbeam 1, and the angle adjustment unit includes a cylindrical pin, which can pass through the first circular hole 11 and the corresponding second circular hole 21 to movably connect the vertical tube 2 to the crossbeam 1, and the cylindrical pin can enable the vertical tube 2 to move left and right in the long hole 12 of the crossbeam 1 while limiting the movement in the front and rear directions.

[0035] As an optional implementation, it also includes a shielding strip 5, which is detachably connected to the crossbeam 1. The shielding strip 5 can shield the first circular hole 11, the second circular hole 21 and the cylindrical pin to make the structure more beautiful, and at the same time can limit the cylindrical pin to avoid separation.

[0036] As an optional embodiment, a connection groove 13 is respectively opened on the front side and the rear side of the cross beam 1. After the connection groove 13 is opened, the cross beam 1 can present a "concave" structure on one side;

[0037] Both ends of each first circular hole 11 pass through two connecting grooves 13 respectively, and the shielding strip 5 is detachably connected to the connecting groove 13. The connecting groove 13 can provide an installation space for the shielding strip 5, making the structural layout more reasonable.

[0038] As an optional implementation, a first clip is provided on the shielding strip 5, and a second clip is provided on the connecting groove 13. The first clip and the second clip form a snap connection, which has good connection strength and is easy to disassemble and assemble, and is convenient for inspection and maintenance.

[0039] As an optional embodiment, the cross-sectional area of ​​the long hole 12 is larger than the cross-sectional area of ​​the vertical tube 2 . Such a configuration can provide a tilting space for the vertical tube 2 to tilt inside the long hole 12 .

[0041] When applied to the connection between an ordinary column and a beam 1, the connection unit 4 only needs to use an ordinary buckle. In this embodiment, a straight buckle is preferably used. Two straight buckles need to be symmetrically arranged at the connection between each beam 1 and the column. The two straight buckles are screwed to the two ends of the beam 1 through the buckle by using a carriage screw, and screwed to the column 3 by using a self-drilling screw through the buckle;

[0042] When applied to the connection between special columns and beams 1, such as corner columns or terminal columns, the connection unit 4 needs to adopt a terminal clip. In this embodiment, a U-shaped clip is preferably used. A U-shaped clip needs to be set at the connection between each beam 1 and the column. The U-shaped clip is screwed to the two ends of the beam 1 through the clip using a carriage screw, and is screwed to the column 3 through the clip using a drill screw.

[0043] As an optional implementation, when the beam 1 is tilted, there is a gap between the beam 1 and the column 3. Such a setting can provide space for the beam 1 to tilt left and right, thereby preventing the beam 1 from scratching the column 3 when tilting. In this embodiment, the value of the gap is preferably 5 mm.

[0044] As an optional implementation, the inclination angle of the beam 1 is 0° to 35°, which can meet the inclination angle of most ground surfaces in daily life and industrial production.

Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
