The invention discloses a tooling-free blind plate. The tooling-free blind plate includes a blind plate body; an arc-shaped groove is formed at two ends of the blind plate body respectively; a plurality of guide components and fixing components are fixed at one side of each arc-shaped groove, wherein the guide components are corresponding to the fixing components; the tooling-free blind plate is made of a plastic material, and the appearance of the tooling-free blind plate is novel and beautiful, and the weight of the tooling-free blind plate is small; and the blind plate can be effectively fixed on a communication cabinet through the guide components and the fixing components at the two ends of the blind plate. Thus, the tooling-free blind plate is advantageous in firm and reliable connection, convenient installation and disassembly, flexible and convenient adjustment and greatly reduced production cost.

The invention relates to a method for making paper containers and discloses a crossed semi-closed carton which is formed by combining a part 1 with a part 2. A piece of rectangular paper which is transversely long and longitudinally wide is used to make the U-shaped part 1, a piece of rectangular paper which is longitudinally long and transversely wide is used to make the U-shaped part 2 between two rectangular boxes, two erect portions of the U shape in the middle of the part 1 are inserted into an interlayer of the part 2 from bottom to top respectively to form an L shape, the L shape is folded to form a semi-box initial shape, and the crossed semi-closed carton can be formed by folding the right half of the rectangular paper which is transversely long and longitudinally wide in that way. The crossed semi-closed carton is unique in concept and novel in design, the parts are simple to make, easy to combine and firm in combining fit, and the crossed semi-closed carton is novel and attractive in appearance.

The invention discloses a space special-shaped arch bridge and a construction method thereof. The space special-shaped arch bridge comprises two supporting structures, a main beam arranged on the twosupporting structures and an arch rib structure arranged on the main beam, the arch rib structure comprises a main arch rib and two auxiliary arch ribs arranged on the two sides of the main arch rib correspondingly, arch feet arranged at the two ends of the auxiliary arch ribs and the main arch ribs are arranged on the upper parts of the middles of the two supporting structures correspondingly, the rise span ratio of the main arch rib is 1 / 5.0-1 / 5.5, and the rise span ratio of the auxiliary arch ribs is 1 / 4.0-1 / 4.5; the main arch rib and the two auxiliary arch ribs are connected through inclined struts correspondingly, and cross struts are arranged on the positions, corresponding to all the inclined struts, between the two auxiliary arch ribs; the main arch rib is connected with the main beam through vertical suspenders, and the two auxiliary arch ribs are connected with the outer sides of the corresponding side of the main beam through inclined suspenders. The space special-shaped arch bridge and the construction method thereof have the characteristics that the structure is light and attractive, the span is large, the bridge is wide, stress is reasonable, and construction is convenient and fast, and the problems that in the existing city view, the bridge pose is single, the cost is high, and construction is difficult are solved.

The invention discloses a bladeless fan.
