The invention relates to an axial piston machine in a swash-plate construction with an actuating device. The actuating device comprises a actuating piston (3) and a mating piston (4). The actuating piston (3) and the mating piston (4) are connected to the swash plate (2) each with the first end thereof and can be applied with the second end thereof with a force acting in the direction of the first end. For resetting the swash plate (2) in the direction of a resting position, an elastic element (10, 11) is provided on the actuating piston (3) and on the mating piston (4), which is supported on a spring bearing (12, 17) arranged on the first side facing the swash plate (2) of the actuating piston (3) or of the mating piston (4). In the other direction, the elastic element (10, 11) is supported on a second spring bearing (13, 18), arranged on the end facing away from the swash plate (2) of the actuating piston (3) or of the mating piston (4). When the swash plate (2) is deflected from the resting position, the second spring bearing (13, 18) of the actuating piston (3) or of the mating piston (4) is supported on a counter bearing on the housing side. The second spring bearing (13, 18) of the respective other actuating bearing (3) or mating bearing (4) is supported on a counter bearing on the piston side.

The invention discloses a mounting component of a decorative sheet. The mounting component comprises fasteners and connecting pieces connected with a flush large-area wall. Convergent type clamping grooves are formed in the connecting pieces, groove openings of the clamping grooves point to the direction far away from the wall, the decorative sheet is clamped and fixed by the fasteners, and clamping joints with the shape of sections meshed with groove cavities of the clamping grooves are arranged on the fasteners. Through the adoption of the technical scheme, the fasteners are in clamping cooperation with the connecting pieces, and therefore when the connecting pieces are connected with the flush large-area wall, it is naturally guaranteed that the fasteners are reliably fixed. Therefore, the fasteners can clamp and fix the decorative sheet laid on the wall stably and reliably, and the mounting component of the decorative sheet is simple in structure, convenient to use and high in decorative sheet fixing strength.

The invention discloses a writing blackboard for English teaching, which is characterized in that a fixing seat is provided with fixing blocks matched with four corners of a mounting seat, the left side and the right side of a main panel are respectively provided with a plurality of left sliding grooves and right sliding grooves, the plurality of left sliding grooves are internally and correspondingly provided with a left side panel in a sliding manner, and the plurality of right sliding grooves are internally and correspondingly provided with a right side panel in a sliding manner. The rotating rod can play a role in supporting the main panel, when the transverse use space of the blackboard is small, the main panel can be turned over by rotating the main panel, the transverse narrower face of the main panel is vertically arranged, the main panel can be fixed by fixing the fixing block and the mounting base, and use is flexible. Meanwhile, the left side panels and the right side panels can be pulled out for use, the left side panels are multiple, used knowledge points can be pushed into the main panel every time, the writing space of the blackboard is greatly increased, and when previous knowledge points need to be reviewed or explained again, the corresponding left side panels or right side panels can be pulled out; and the teaching efficiency is improved.

The invention discloses a cargo packaging device. The cargo packaging device comprises flexible bands and first elastic bands, wherein each flexible band comprises a ring-shaped flexible band main body and a first fracture arranged on the flexible band main body, the two sides of each first fracture are respectively a first open end and a second open end at the two ends of the flexible band main body, the length of the side of each first open end is equal to the length of the side of the corresponding second open end, each first elastic band is provided with a first connecting end and a second connecting end at the two ends, each first connecting end and the corresponding first open end are fixedly connected to form a first fixed connecting point, each second connecting end and the corresponding second open end are fixedly connected to form a second fixed connecting point, and the position, on the side of the corresponding first open end, of each first fixed connecting point is the same as the position, on the side of the corresponding second open end, of the corresponding second fixed connecting point. The invention additionally discloses a packaging method using the cargo packaging device. The cargo packaging device and the method have the advantages that cargoes can be conveniently and efficiently packaged, the effects of environmental friendliness and repetitive use are realized, the cleaning is facilitated, and the packaging cost is low.

The invention discloses an amphibious aircraft buoy detection device and a detection method thereof, and relates to the technical field of aircraft buoy detection devices; in order to facilitate the detection of the buoyancy of the aircraft buoy at the corresponding draft; the device includes a water tank and a press-down mechanism. A hydraulic cylinder is installed on one side of the water tank through a supporting frame, and the pressing mechanism includes a first fixing frame and an arc-shaped pressing plate; the method includes the following steps: pouring water into the water tank, and placing the aircraft buoy to be tested in the water tank. The present invention can drive the adjustment frame to move downwards while the arc-shaped pressing plate is pressed down by arranging structures such as an air bag, a conductive ring, and a conductive sheet, while the air bag maintains the original position based on the buoyancy support slide bar. When the arc-shaped pressing plate is pressed down to a certain Distance, the conductive ring contacts and conducts the circuit between the two conductive sheets, the control component receives the electrical signal, and then locks the display on the display screen. This method can effectively obtain the buoyancy of the aircraft buoy at the corresponding draft.
