A computer container comprises a side plate, a front plate and a locking device, and the locking device is equipped on the front plate. The locking device includes a driver element and a sliding vane. The said driver element is rotary equipped on the front plate, and drives the sliding vane to slide on the front plate. At the same time, when the sliding vane withstands the side plate, the driver element limits the sliding movement of the side plate relative to the front plate.

The invention discloses a prefabricated bridge panel expansion joint connecting member, and belongs to the technical field of expansion joint connecting members. The prefabricated bridge panel expansion joint connecting member comprises a plurality of sub-members arrangedin the length direction of expansion joints, vertical supporting blocks are arranged in acontaining cavity formed by oppositelyarranging the opening ends of a first U-shaped fastener and a second U-shaped fastener of the sub-members, buffer mechanismsare symmetrically arranged on the left sidesand the right sides of the vertical supporting blocks,elastic filler layersarearranged between two vertically adjacent profiled steel sheet assemblies as well asbetween the profiled steel sheet assemblies and the first U-shaped fastener as well as betweenthe profiled steel sheet assemblies and the second U-shaped fastener,L-shaped through grooves are formed in the overlapping portion of the first U-shaped fastener and the secondU-shaped fastener, fastening bolts are arranged in the L-shaped through grooves, vertical through holes are formed in the vertical supporting blocks, screwed pipes are pre-embedded at the bottoms ofthe expansion joints, and the lower ends of the fastening bolts penetrate through the L-shaped through grooves and the vertical through holes to be connected with the screwed pipes. The prefabricatedbridge panel expansion joint connecting member has the characteristics of being high in toughness, high incapacity forresistingexpansion joint deformation, and capable of realizingtimesaving and laborsaving in installation and maintenance.

The invention provides a winding type dust removal screen window. The winding type dust removal screen window comprises a main frame and a roll dust removal net. An upper scroll and a lower scroll are correspondingly arranged on the upper and lower sides of the frame. The shaft ends of the upper scroll and the lower scroll are correspondingly arranged in an upper bracket and a lower bracket in a penetrating manner to form rotational connection. The extending ends, going out of the lower bracket, of the lower scroll are each sleeved with a rotating wheel. The front side face of the main frame is a screen window face, and the rear side face is an installation face which is fixed to a window frame. A pressing frame is arranged on the screen window face, the pressing frame and the upper bracket are connected through a hanging assembly, and the pressing frame and the lower bracket are fixedly connected by a lower connecting rod. The main frame is equipped with a dust removal net channel. The periphery of the main frame and the periphery of the pressing frame are closely sealed together, and the periphery of the main frame and the periphery of the window frame are closely sealed together. The roll dust removal net includes a piece of rectangular mesh fabric. The two ends of the mesh fabric are each wound to form a roll. The middle of the mesh fabric is arranged in the dust removal net channel in a penetrating manner, so that the roll at one end sleeves the upper scroll, and the roll at the other end sleeves the lower scroll.
