The invention discloses a containing box for containing daily necessities. The containing box comprises a first box body and a second box body. The second box body is movably arranged on the bottom side of the first box body. The first box body and the second box body are arranged in an opened manner. Installing blocks are fixedly arranged on the two sides of the second box body. The sides, away from each other, of the two installing blocks are rotationally provided with first U-shaped rods. First clamping grooves are formed in the two sides of the first box body. The ends, close to each other, of the two first U-shaped rods extend into the first clamping grooves correspondingly. Two cover plates are movably arranged on the top side of the first box body, and the two sides of the first boxbody are rotationally provided with two connecting rods. According to the containing box, the first box body can be conveniently installed on the top side of the second box body, accordingly more convenience is achieved during storage of the containing box; after the cover plate is opened, the cover plate can be stored on one side of the first box body, the space occupied by the cover plate is reduced, and the space of the first box body can be flexibly divided according to needs.

The invention relates to a footrest extension mechanism and a seat telescopic device. The footrest extension mechanism comprises a first connecting rod, a second connecting rod, a third connecting rod, a fourth connecting rod, a first footrest piece, a linkage rod, a second footrest piece and a footrest connecting piece, one end of the second connecting rod is hinged to the first footrest piece, the other end of the second connecting rod is hinged to the first connecting rod, the first connecting rod is used for being hinged to a linkage support of a seat, one end of the fourth connecting rod is hinged to the second footrest piece, the other end of the fourth connecting rod is hinged to the third connecting rod, the first footrest piece is hinged to one end of the linkage rod, and the other end of the linkage rod is hinged to the middle of the fourth connecting rod; one end of a first connecting piece of the footrest connecting piece is hinged to the middle of the second footrest piece, the other end of the first connecting piece is hinged to one end of a second connecting piece, the other end of the second connecting piece is hinged to the middle of a second connecting rod, and the middle of the second connecting piece is hinged to the middle of a fourth connecting rod. The footrest extension mechanism is advantaged in that adjusting flexibility of the footrest extension mechanism can be improved, and the extension length of the footrest extension mechanism can be increased.

A separation or reaction unit (1; 1′; 81; 81′; 101) and a method for aseptically connecting such units. The separation or reaction unit (1; 1′; 81; 81′; 101) comprises at last one fluid inlet (3a, 3b, 5a, 5b; 3a′, 3b′, 5a′, 5b′; 85a, 85b; 103a, 103b) and at least one fluid outlet (3a, 3b, 5a, 5b; 3a′, 3b′, 5a′, 5b′; 85a, 85b; 103a, 103b). At least one of the inlet or outlet is sealed by at least one film (7, 9; 11; 87a, 87b; 107a, 107b) and the contact surface between the film and the separation or reaction unit is aseptic. The films are adapted to be mated with a corresponding film on another separation or reaction unit or on a fluid distribution unit (20; 57; 61) which the separation or reaction unit possibly should be connected with and said mated films are adapted to be pulled out together two and two after mating such that corresponding fluid inlets / outlets on the two connected units are mated aseptically.

The invention relates to a civil air defense basement structure, which includes an underground passage, a basement adjacent to the underground passage, an explosion-proof wall arranged between the underground passage and the basement, and an explosion-proof wall connected to the underground passage and the first door opening of the basement; a closing system for closing the first door opening is installed in the first door opening and the basement, and a camouflage system is installed on the first door opening on one side of the underground passage; the closing The system includes an explosion-proof door that can be opened or closed from the first door opening, and the camouflage system includes a billboard installed on the first door opening on one side of the underground passage. The present invention increases the concealment of the first doorway by arranging a billboard on the side of the first doorway located in the underground passage, and improves the time for the enemy to find the basement entrance, thereby gaining more time for the people to escape.

The invention discloses a two-direction pre-stressed prefabricated hollow concrete slab and a manufacturing method thereof. The two-direction pre-stressed prefabricated hollow concrete slab comprises a transverse-hole pre-stressed prefabricated hollow concrete slab and a longitudinal-hole pre-stressed prefabricated hollow concrete slab; the two-direction pre-stressed prefabricated hollow concrete slab is characterized in that the transverse-hole pre-stressed prefabricated hollow concrete slab comprises upper panels, lower panels, longitudinal ribs, transverse ribs and end ribs, which are integrally cast to form a transverse-hole hollow slab body, holes are horizontally formed in the transverse-hole hollow slab body, corrugated pipes are arranged on the transverse-hole hollow slab body, the longitudinal-hole pre-stressed prefabricated hollow concrete slab comprises upper panels, lower panels, longitudinal ribs, side ribs, end ribs and transverse ribs, which are integrally cast to form a longitudinal-hole hollow slab body, and holes are formed in the longitudinal-hole hollow slab body and parallel to the longitudinal ribs. The invention also provides a production line and a manufacturing method. The two-direction pre-stressed prefabricated hollow concrete slab has reasonable structure robustness; the pre-stressed ribs in the longitudinal and transverse directions are combined to form a reliable tie bar system, a clear load force transfer path is provided, and the continuity, the ductility and the overall stability of the structure are improved.

The invention relates to a method for creating a post engineering information model for a railway and urban railway traffic station. Rail traffic engineering construction involves a plurality of fields and has complex links and a large amount of information, the entire process is perfected continuously with the addition and optimization of all engineering information, and the requirement on total planning of the entire process is high. The method comprises the following steps: making a single functional department create an information model of the department and establish a working set of the department; gathering the working sets of all departments onto the same working platform by sharing elevation and a shaft screen to integrate into a project working set; embedding plant feature information, design information and construction information into a system to form completion data for an operator; gradually separating the information, and constructing task flow in real time according operation for loading and outputting; and releasing cache after finishing output, and recording a log file. According to the method, various types of relevant information in a project are integrated reasonably through a parameter information model, and the created information model is shared and transmitted in a full life cycle process, so that the engineering progress is effectively optimized.
