It should be understood that these descriptions are only exemplary, and are not intended to limit the scope of the technical solution.

Example 1

As shown in Figures 1-12, this embodiment proposes a sunshade device for gardens that can be adjusted at multiple angles, including a sunshade device A and a sunshade device base B, and the sunshade device base B includes a bottom plate 10, a top plate 20, and a tappet assembly 30. The hinged bracket assembly 40, the height adjustment assembly 50 and the equipment support rod assembly assembly 60, wherein the tappet assembly 30, the hinged bracket assembly 40 and the height adjustment assembly 50 are installed between the bottom plate 10 and the top plate 20, the bottom plate 10 and the top plate 20 The middle part is hinged by a hinged bracket assembly 40. There are at least two sets of lifter assemblies 30. The lifter assemblies 30 are installed on the front part of the bottom plate 10 and the top plate 20, and the main body of the lifter assembly 30 is an air pressure lifter 33. The two ends are respectively hinged with the base plate 10 and the top plate 20, and the height adjustment assembly 50 is installed at the rear of the base plate 10 and the top plate 20. 40 to adjust the inclination angle of the top plate 20; the equipment support bar assembly assembly 60 is installed on the top surface of the top plate 20, and is used to connect the lower end of the equipment support bar of the sunshade device.

In other embodiments, the third ball joint 42 can be replaced by a one-way hinge or a universal joint.

Specifically, the main bodies of the base plate 10 and the top plate 20 are rectangular plate-shaped bodies. In a normal state, the base plate 10 is parallel to the top. Orientation settings. The main body of the lifter assembly 30 is an air pressure lifter 33, and the two ends of the air pressure lifter 33 are respectively hinged with the bottom plate 10 and the top plate 20. The end of the outlet end is hinged with the base plate 10 through the first ball hinge 31 , the top of the air pressure lifter 33 is a cylinder body, and the upper end of the air pressure lifter 33 is hinged with the top plate 20 through the second ball hinge 32 .

In addition, because the air pressure tappet 33 is used for a long time, it is easy to cause asynchronous expansion and contraction.

After the angle of the sunshade device A is adjusted, the pressure on the front of the top plate 20 changes linearly after it is tilted forward, and the support force provided by the air pressure lifter 33 changes linearly with the degree of compression. Therefore, the air pressure lifter 33 has two functions. The effect is that when the sunshade device base B is connected to the sunshade device A, after the top plate 20 adjusts the inclination angle, because the center of the sunshade device A leans forward, the air pressure lifter 33 is compressed, so that the force on the top plate 20 is generally balanced; the second function is, The air pressure lifter 33 has a upward tendency. When the top plate 20 is reset to a horizontal angle from an inclination angle, the air pressure lifter 33 can provide a support force for lifting the top plate 20 up, so that the operation of resetting the top plate 20 to level the process uses less power.

In this embodiment, the two tappet assemblies 30 and the hinged bracket assemblies 40 form a triangular arrangement. And the hinged bracket assembly 40 is arranged at the rear position between the base plate 10 and the top, so when adjusting the inclination angle of the top plate 20, it is easy to move the center of gravity of the sunshade device A forward so that the air pressure lifter 33 in the lifter assembly 30 is compressed .
