The fresh air top air supply and top air return design structure comprises a ceiling structure composed of a keel structure layer, a gypsum board, a capillary network, a gypsum mortar layer and a putty emulsion paint layer. The height of the suspended ceiling structure is not greater than 100mm; a capillary main pipe is laid in the keel structure layer between the gypsum board and the floor, and capillary tubes in the capillary network penetrate through the gypsum board to be communicated with the capillary main pipe; fresh air pipelines are laid in the keel structure layer between the gypsum board and the floor slab and comprise an air supply pipeline and an air return pipeline, the air supply pipeline and the air return pipeline are provided with an air supply opening and an air return opening respectively, and holes used for installing the air supply opening and the air return opening are formed in the gypsum board; on the premise of ensuring the indoor clear height of 2.60 m, the floor height of the residence can be designed to be 2.95 m, for a residence building with the limited height of 80 m, one more floor can be built compared with a floor air supply design, the plot ratio of the building is increased, and large economic benefits are brought.

The utility model relates to a honeycomb oil smoke and particulate matter purification and dust removal device which comprises electrode stands and a corona cavity mechanism, the peripheries of the inner sides of the two electrode stands are respectively connected with two frames through porcelain insulators, the electrode stands are connected with the frames through a plurality of tension springs, and the corona cavity mechanism is installed between the two frames; a tenon-and-mortise structure is reserved on an extruded regular hexagonal honeycomb profile through die design, the profile is overlapped at the tenon-and-mortise structure to form a corona cavity after being cut, meanwhile, overlapped cavities are connected through a connecting buckle, the regular hexagonal profile and the connecting buckle are combined through the tenon-and-mortise structure, and therefore the corona cavity is formed. The whole structure is mainly composed of the electrode stand, the corona wire, the corona cavity and the porcelain insulator, the overall stability of the structure is high, the volume ratio is large, the purification efficiency is high, the material utilization rate is high, the size is small, the purification efficiency is improved, the structure is firmer and more reasonable, and raw materials are reduced.

The utility model belongs to the technical field of sound boxes, and particularly relates to a sound box structure, which comprises a sound box main body and an integrated control unit arranged on the surface of the sound box main body, and the surface of the sound box main body is also provided with an audio interface female seat independent of the integrated control unit. According to the utility model, the long audio interface female seat is installed on the surface of the sound box main body and is independent of the integrated control unit, so that the overall thickness of the integrated control unit is reduced, and when the integrated control unit is installed with the sound box main body, the integrated control unit occupies a small space inside the sound box main body, thereby effectively improving the volume ratio inside the sound box main body, and improving the volume ratio of the sound box main body. Therefore, the bass effect of the loudspeaker box is improved.

This invention relates to the field of refrigeration equipment and provides a refrigerator. The refrigerator includes a cabinet; a pair of doors hinged to the cabinet, without a flip beam on the doors, and door sealing components on the mating edges of the doors. When the doors are closed, the door sealing components on one door press against each other, and the door sealing components on both doors are adapted to fit snugly against the cabinet. This refrigerator replaces the traditional flip beam with a coordinated sealing effect of the door sealing components, freeing up storage space in the doors and cabinet, resulting in a more regular internal cavity layout and a significantly improved overall volume ratio, meeting more storage needs of users. The flip beam-free design eliminates the operating noise of the flip mechanism, and combined with the elastic deformation characteristics of the door sealing components, the door opens and closes more quietly and smoothly, enhancing the high-end user experience of the refrigerator; the door sealing components are compatible with ordinary single and double axis hinges, eliminating the need to modify the cabinet structure or replace with special hinges, simplifying the refrigerator structure and reducing production and modification costs.

The application discloses a conveying line carrier with stress structure on the lower side, which comprises a coupling frame, and further comprises: a front walking part arranged on the front side of the coupling frame and provided with a front stress rod, the stress end of the front stress rod extending to the lower side to receive the pushing force of a pushing piece on the conveying line; a rear walking part arranged on the rear side of the coupling frame and provided with a movable rear stress rod, a first elastic force acting on the rear stress rod to make the stress end of the rear stress rod deviate from the running track of the pushing piece; and a middle stress rod movably arranged on the lower side of the coupling frame and located in the interval between the front walking part and the rear walking part, a second elastic force acting on the middle stress rod to make the stress end of the middle stress rod deviate from the running track of the pushing piece. The stress end of the middle stress rod and the stress end of the rear stress rod are both provided with pressure receiving structures for receiving the pressure of a pressure piece arranged on the conveying line to make the stress end of the middle stress rod and the stress end of the rear stress rod extend into the running track of the pushing piece.

This application belongs to the field of fiber drawing machine technology and discloses a reciprocating multi-station multi-variety glass fiber ply yarn drawing machine, including a frame and a base plate. The base plate has two mounting holes, one above the other, each containing a turntable. Two sets of main shaft impeller mechanisms are slidably mounted on the turntables along the length of the frame. A tilting mechanism and a reciprocating mechanism are respectively installed inside the frame corresponding to the two turntables. The tilting mechanism drives the two sets of main shaft impeller mechanisms on the turntables to switch between working and standby positions. The reciprocating mechanism drives the main shaft impeller mechanism in the working position to slide along the length of the frame. A forced yarn splitting mechanism, a yarn blocking mechanism, a yarn arrangement mechanism, a water pipe mechanism, and an automatic yarn unloading mechanism are respectively installed on the frame corresponding to the two turntables. An automatic yarn feeding mechanism is slidably installed at the bottom of the frame. This application forms a dual-drawing station, which can independently carry out drawing operations without interference. It can be adapted to high-flow spindles or multiple spindles to increase yarn production and reduce the floor space of the production line.
