The invention discloses a quick assembly type building structure. The quick assembly type building structure comprises assembly mechanisms, a fixing mechanism, connecting mechanisms and a plate mechanism. The assembly mechanisms are located at the top of the fixing mechanism and can move on the surface of the fixing mechanism, the connecting mechanisms are located in the assembly mechanisms, and the assembly mechanisms can be fixedly connected through the connecting mechanisms. The plate mechanism is located between the assembly mechanisms and the fixing mechanism, the plate mechanism can achieve sealed connection of the assembly mechanisms and the fixing mechanism. According to the quick assembly type building structure, the structure built by the quick assembly type building structure is stable, the situations such as loosening cannot occur, and the quick assembly type building structure can be rapidly built for use in emergency; and the situations of deformation, bending and the like of the structure under the condition of long-time acting force can be prevented, so that the service life is long, and the safety performance is high.

Gas electromagnetic valve
ActiveCN113464708AReduce in quantityQuick installationOperating means/releasing devices for valvesValve housingsPhysicsRotary valve
The invention discloses a gas electromagnetic valve. The gas electromagnetic valve comprises a valve seat, a coil assembly, an iron core assembly and a valve cover, the iron core assembly is installed in an installation groove in the front end of the valve seat, the coil assembly is connected to the iron core assembly in a sleeving mode and matched with the iron core assembly in a limiting mode, the valve cover is matched with a plurality of limiting grooves formed in the side wall of the front end of the valve seat through a plurality of clamping hooks arranged at the rear end, the valve cover is connected with the valve seat, meanwhile, the valve cover extrudes the iron core assembly through a pressing block, when the valve cover needs to be separated from the valve seat, the valve seat or the valve cover is rotated, and separation of the clamping hooks and the limiting grooves can be achieved. The gas electromagnetic valve has the beneficial effects that the coil assembly in double-framework flexible connection can reduce the number of wiring terminals and is convenient to install at the same time; the clamping hooks are matched with inclined faces on the two sides of the limiting grooves, so that the valve cover and the valve seat are detached by rotating the valve seat or the valve cover; and the iron core assembly of a double-mounting-seat combined structure facilitates the follow-up disassembly of the coil assembly while facilitating the limiting of the coil assembly.
