[0014] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0015] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0016] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0017] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0018] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0019] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0020] Example This embodiment provides a sleeper at the bottom of a hanging basket with adjustable bridge deck cross slope, such as... Figures 1 to 3 As shown, it includes a wedge block 1000 and a connector 2000. The cross-section of the wedge block 1000 is a right trapezoid with an included angle of 45° between its two sides. A through hole 2000 is provided between the lower base and the longer side. A pair of wedge blocks 1000 are arranged symmetrically and connected to each other by a connector 3000 passing through the through hole 2000.

[0021] By changing the distance between the two ends of the connector 3000, the height of a pair of wedge blocks 1000 can be adjusted to adapt to different cross slopes. The wedge block 1000 decomposes the vertical force into a horizontal force through the inclined surface of its longer waist, and then the connector 3000 constrains the horizontal force to achieve a fixed height.

[0022] In this embodiment, a pair of wedge blocks 1000 can slide along the length of the inclined surface formed by the longer waist, and the height can be adjusted by the relative sliding between the two.

[0023] In this embodiment, the wedge block 1000 is made of metal to facilitate bearing the weight of the hanging basket.

[0024] In this embodiment, the ends of the through hole 2000 extend along the length of the lower bottom and the longer waist, respectively, and their ends are elongated to allow for adjustment by the connector 3000. In this embodiment, multiple through holes 2000 are provided to enhance the overall structural stability.

[0025] In this embodiment, the connector 3000 is a screw assembly, which includes a pull rod and nuts at both ends. After the pull rod passes through the through holes 2000 of a pair of wedge blocks 1000, its end is connected to the nut. A washer is provided between the nut and the wedge block 1000.

[0026] The gasket has holes for the screw to pass through. The number of holes is the same as the number of through holes 2000. Multiple connectors 3000 use the same gasket, which helps to enhance the overall structural stability.

[0027] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0028] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
