The invention discloses a staggered interlocking prefabricated concrete floor system, which comprises a plurality of prefabricated floor slabs with interlocking and interlocking front and back interlocking interlocking interlocking installation and use of a plurality of concave-convex grid-like tooth grooves, and the upper and lower prefabricated floor slabs pass through the interlaced concave-convex The grid-shaped tooth grooves are tightly occluded and connected, and the joints between the slabs are staggered. The slab seams between two adjacent prefabricated slabs are pasted with FRP fiber cloth and epoxy resin. The strips are connected into a whole. The present invention provides a brand-new prefabricated assembled floor plan, which is novel and reasonable in design, adopts the basic idea of ​​"one-way prefabrication, positive and negative interlocking, staggered joints, joint reinforcement", and combines "large slab prefabrication, split use "The prefabrication process uses the characteristics of the floor slab to complete the assembly construction. The cast-in-place strips at the end of the slab and the reinforcement of FRP fiber cloth at the seam of the slab can effectively improve the overall performance of the assembly floor structure and the efficiency of prefabricated construction, saving human resource costs and economic benefits. Significantly, it is beneficial to popularize and use.

The invention relates to washing machine technology, in particular to a wall-mounted washing machine bracket and a washing machine. The wall-mounted washing machine bracket includes a sliding rail, a sliding seat and a fixing seat; the sliding rail extends in the first direction, and the sliding seat is slidably fixed to the sliding rail; the sliding seat includes a ferromagnetic part and a limiting part , the limiting piece is slidably limited to the slide rail; the fixing base includes a connecting base for connecting to the washing machine and an active magnetic attraction piece, the active magnetic attraction piece magnetically attracts and fixes the ferromagnetic piece. By energizing the magnets to increase the magnetism, this allows the washing machine to attach to the wall.

The invention relates to a supercapacitor which comprises a metal housing, a core and a cover board, wherein the core is accommodated in the metal housing, the metal housing comprises an open end and a closed end at the other opposite end, and the closed end extends outwards to form a pole; a polar plate which is in electrical contact with the metal housing is arranged at one end, near to the closed end of the metal, of the core; a threaded through hole is formed on the pole along the axial line of the pole in a vertical downward manner; and a stud bolt matched with the threaded through hole is arranged on the polar plate. The core and metal housing of the supercapacitor are convenient and stable and firm to assemble, the operation is simple, and the defect that the polar plate is separated from the pole at the closed end of the metal housing due to the shaking of the core is overcome.

The invention discloses a touch display device. The touch display device includes: a face frame, an infrared touch panel, an infrared component and a backplane; the face frame includes a component mounting part, a panel mounting part and a connecting part, and the connecting part is along the touch display The thickness direction of the device extends toward the side facing away from the mounting surface of the panel mounting portion; the infrared touch panel is mounted on the mounting surface of the panel mounting portion; the infrared component is mounted on the component mounting portion the backplane includes a bottom plate and a side edge extending from the edge of the bottom plate toward the infrared touch panel; the connecting portion of the face frame is correspondingly connected with the side edge of the backplane.
